In view of the deficiencies in the prior art, the present invention is to provide a water meter detection device. By pressing the drive rod, the splint is in contact with or separated from the slide plate, and the purpose of facilitating the movement of the clamp block is achieved.
The figure is a schematic diagram of the external structure of the present invention
To achieve the above objectives, the present invention provides the following technical solutions: A water meter detection device includes a water storage tank and a support frame, a slide plate is connected along the length direction of the support frame, and a water inlet for connecting with the water storage tank is connected to the support frame. And the water outlet seat, the sliding block is connected with a clamp block between the water inlet seat and the water outlet seat, and the clamp block comprises a connection part and a sealing part for connecting with the water meter, the connection part is connected with a clamping plate, and the connection part is provided with a drive The rod is connected to the splint through a transmission assembly, and the transmission assembly is connected to the connection portion. The drive rod moves along its own length through the transmission assembly to drive the splint to interfere with the slide plate or separate from the slide plate. The splint and the connection portion are respectively disposed on both sides of the slide plate. .
When it is required to move the clamping block, the clamping plate is driven to move through the driving assembly by pressing the driving rod, so that the clamping plate is separated from the sliding plate. At this time, the clamping block is supported by the connecting portion, so that the clamping block can be easily moved and the sealing portion and the water meter are After connecting, press the driving rod again, so that the driving rod drives the clamping plate to move toward the sliding plate through the transmission component, and the connecting part placed on both sides of the sliding plate and the clamping plate simultaneously collide with the sliding plate to position the clamping block; When the slide is positioned, it is not easy to produce a large height difference on the slide, so that the water can flow more smoothly through the water meter, making the reading more accurate.
The present invention further provides that the transmission assembly includes a positioning seat, a first slider, a second slider, a guide block, and an elastic member. The positioning base is fixed on the connecting portion. The first slider is connected with the driving rod and is slidingly connected to the positioning base. In the middle, the second slider is slidably connected to the positioning seat and is connected with the clamp plate. The first slider has a first inclined surface opposite to an end of the driving rod, and the second slider is provided with an end facing towards the first slider. The inclined second surface is fitted with a second inclined surface. The positioning base is provided with a third inclined surface and a sliding groove along the length direction of the positioning base, and the guiding block is embedded on the third inclined surface or is disposed in the sliding groove.
When the driving rod is moved along the length direction of the driving rod, the second sliding block is moved away from the positioning seat through the guiding action of the first inclined surface and the second inclined surface, and is rotated by a certain angle to make the guiding block and the third inclined surface Correspondingly, the drive rod is loosened, and the guide block is embedded on the third slant surface through the elastic force of the elastic member, and then the splint is positioned. At this time, the splint is separated from the slide plate to facilitate the movement of the clamp block and the drive lever is pressed again. The second slider rotates at a certain angle, after loosening the driving rod, the guiding block is placed in the chute and moves in a direction close to the first slider through the elastic force of the elastic member, and the friction between the splint and the slide plate is generated. Force the clamp to position.
The splint is connected with the second slider through the limit assembly. The arrangement of the limiting component can make the second sliding block not easily rotate the splint when it is rotated, which reduces the mutual abrasion between the splint and the sliding plate and prolongs the service life. The limiting component comprises a rotating wheel and a limiting rod, the limiting rod is fixed on the connecting part, the clamping plate is slidably connected with the limiting rod along a length direction of the limiting rod, and the clamping plate is rotated relative to the second slider through the rotating wheel. During the rotation of the second slider, the rotation wheel is driven to rotate, and at the same time, the limitation effect of the limiting rod on the clamping plate is generated, so that relative rotation between the second slider and the clamping plate is generated, so that the clamping plate can be along the limiting rod. While moving in the length direction, it is not easy for the slide plate to move relative to one another, reducing wear of the splint and the slide plate. The rotating wheel includes an inner ring, an outer ring and a ball. The inner ring is connected to the outer ring through ball rotation. The inner ring is fixedly connected to the second sliding block, and the outer ring is fixedly connected to the clamping plate. When the second slider is rotated by the guiding action of the first inclined surface and the second inclined surface, the inner ring is driven to rotate, and the rolling of the ball causes the relative movement between the inner ring and the outer ring to realize the splint and the second slider. Relative movement.
A seal ring is fixed to the inner wall of the seal portion. The setting of the sealing ring can increase the sealing between the sealing portion and the water meter. When the water flows into the water meter, water does not easily leak out from the gap between the sealing portion and the water meter, reducing the error. A plurality of water outlet holes are opened on the support frame, and a water storage tank is placed below the support frame. After the water meter is tested, because there is a part of water in the water meter, when the water meter is removed from the clamp, the water falls on the support frame and enters the water storage tank through the water outlet hole to facilitate the collection of water. The storage tank communicates with the storage tank through the unloading pipe. Importing the water in the storage tank into the storage tank can realize water circulation, save water resources and protect the environment. The slide plate is connected with the support frame through the support bar, and the support bar is connected with the support frame through the lock piece. The support bar can raise the level of the slide plate so that the worker can easily install and remove it, thereby improving the production efficiency. The water inlet seat includes a water inlet pipe and a support base, and the water inlet pipe is slidably connected to the support base through a hydraulic cylinder, and an end of the water inlet pipe that is far from the hydraulic cylinder is in communication with the water storage tank. The hydraulic cylinder pushes the inlet pipe to communicate with the water meter. At the same time, through the pressure of the hydraulic cylinder, the connection between the water meter and the sealing part, and the connection between the water meter and the water inlet pipe can be made closer, further reducing the error.
The beneficial effect of the present invention is that when the clamp needs to be moved, the drive rod is pressed so that the drive rod pushes the first slider and the second slider to move away from the drive rod, and the guiding effect of the first inclined surface and the second inclined surface is achieved. After the second slider is separated from the positioning seat, rotation occurs, the guide block is corresponding to the third inclined surface, and the guide block is embedded on the third inclined surface through the elastic force of the elastic member to achieve the separation of the splint and the slide plate; When the clamp block needs to be positioned, the drive lever is pressed again. Similarly, the second slide block is rotated, the guide block is corresponding to the slide groove, and the guide block is moved along the length of the slide groove by the elastic force of the elastic element. The clamping block interacts with the slide plate through the elastic force of the elastic member, and the generated frictional force locates the clamping block, which is easy to operate.
