Description

Technical Field

[0001] This utility model relates to the field of gas meter testing, specifically a push-top structure for gas meter testing. Background Technology

[0002] The gas meter only has a small glass window showing a digital dial with seven digits: the first four digits are black, and the last three are red. People's daily cooking fuels have shifted from conventional energy sources like firewood and coal, which are wasteful and polluting, to clean energy sources like natural gas, coal gas, and even electricity. This is where the gas meter comes in. Its automatic accumulation function allows households using natural gas or piped gas to easily know how much gas they have used, so they can pay according to the monthly gas consumption in cubic meters. After the gas meter is manufactured, its airtightness and accuracy need to be tested. During the testing process, a pusher is used to push the gas meter's interface onto the testing port for fixation before testing. Currently, the existing pusher consists of a push plate, a cylinder, and a limit rod. When using it, the worker aligns the gas meter interface with the testing equipment's interface, and then the pusher moves to hold the gas meter in place. However, the worker needs to hold the pusher with their hand until it touches the gas meter. During this process, there is a high risk of the pusher's push plate getting caught in the gap between the pusher and the gas meter, posing a certain safety hazard.

[0003] For example, the utility model disclosed in publication (announcement) number CN219736525U is a pusher for detecting gas meters to prevent hand pinching. It includes a base box, with fixed seats fixedly connected to the lower ends of both sides of the fixed base. An inner box is slidably connected inside the base box, and a lifting component for driving the inner box to move downwards is provided inside the base box. Limiting rods are slidably connected to the four corners of the inner box. An electric cylinder for driving a push plate to move up and down is provided in the middle of the lower end face of the inner box. Limiting grooves are provided in the middle of the upper end face of the push plate near the four sides, and limiting components for limiting the gas meter are provided in each limiting groove. This utility model, through its U-shaped frame, can limit the gas meter during use, eliminating the need for staff to hold the gas meter while pushing it, effectively preventing hand pinching.

[0004] The structure of the above-mentioned utility model uses four U-shaped frames to clamp and fix the gas meter, which facilitates the gas meter testing process. However, the four U-shaped frames operate independently, so it cannot be guaranteed that the gas meter will always be in the center of the workbench after being fixed, which makes the gas meter testing process inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a push-top structure for gas meter detection, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a push-top structure for gas meter detection, comprising a base box, a movable plate slidably connected inside the base box, and several electric cylinders fixedly installed at the bottom of the inner wall of the base box, the movable end of each electric cylinder being fixedly connected to the bottom of the movable plate, and a bottom block being fixedly connected to the top of the movable plate by several uprights, a first clamping component being fixedly installed on the bottom block along the centerline direction, and second clamping components being symmetrically arranged on both sides of the bottom block on the first clamping component.

[0007] Preferably, the top of the bottom block has a strip-shaped groove in the centerline direction, and the first clamping assembly includes support blocks symmetrically fixed inside the strip-shaped groove.

[0008] Preferably, the two supporting blocks are rotatably connected to a rotating shaft at their center positions, and the rotating shaft has symmetrically arranged threaded structures with opposite helical directions on both sides. Each threaded structure of the rotating shaft has a movable block threadedly fitted on its outer side, and the outer side of each movable block is in smooth contact with the inner wall of the strip groove.

[0009] Preferably, the two second clamping assemblies include mounting base plates symmetrically mounted on the top ends of the other two sides of the base block, and a hydraulic cylinder is fixedly mounted on the top end of each mounting base plate.

[0010] Preferably, each of the movable blocks and the movable end of the hydraulic cylinder are respectively fixedly connected to a clamping plate, and the four clamping plates are distributed in a rectangular shape.

[0011] Preferably, the four clamping plates are fixedly provided with rubber pads on one side close to each other, and the two hydraulic cylinders are externally connected to the same controller.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention connects multiple electric cylinders to the same control circuit, synchronously controlling the cylinders to move the movable plates vertically. The gas meter to be tested is placed on top of the base block. Rotating the shaft causes the threaded structure to move the threaded movable blocks closer together or further apart. The clamping plates and rubber pads at the top of each movable block clamp and fix both sides of the gas meter. Simultaneously, two movable blocks move synchronously, pushing the gas meter to the center position. Then, two hydraulic cylinders are synchronously controlled, their movable ends driving two more clamping plates and rubber pads to clamp and fix the other two sides of the gas meter. This clamping and positioning of the other two sides of the gas meter, through the synchronous adjustment of the four clamping plates, ensures that the gas meter is always centered on the top of the base block, facilitating the testing process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figures 1-2 The diagram shows a push-top structure for gas meter detection, including a base box 1. A movable plate 2 is slidably connected inside the base box 1, and several electric cylinders 3 are fixedly installed on the bottom of the inner wall of the base box 1. The movable end of each electric cylinder 3 is fixedly connected to the bottom of the movable plate 2, and a bottom block 5 is fixedly connected to the top of the movable plate 2 through several uprights 4. A first clamping component 6 is fixedly installed on the bottom block 5 along the center line, and second clamping components 7 are symmetrically arranged on both sides of the bottom block 5 on the first clamping component 6.

[0020] In this embodiment, the top of the bottom block 5 has a strip-shaped groove 501 in the center line direction, and the first clamping assembly 6 includes a support block 61 symmetrically fixed inside the strip-shaped groove 501. The center of the two support blocks 61 is rotatably connected to a rotating shaft 62, and the two sides of the rotating shaft 62 have symmetrically opened threaded structures with opposite spiral directions. Each threaded structure of the rotating shaft 62 is threadedly fitted with a movable block on the outside, and the outside of each movable block is in smooth contact with the inner wall of the strip-shaped groove 501. The two second clamping assemblies 7 include mounting base plates 71 symmetrically installed on the top of the other two sides of the bottom block 5, and each mounting base plate 71 is fixedly mounted with a hydraulic cylinder 72 at its top. Each movable block and the movable end of the hydraulic cylinder 72 are fixedly connected with a clamping plate 73, and the four clamping plates 73 are distributed in a rectangular shape. Rubber pads 74 are fixedly provided on one side of the four clamping plates 73 that are close to each other. The two hydraulic cylinders 72 are externally connected to the same controller.

[0021] Furthermore, multiple electric cylinders 3 are externally connected to one end of the same control circuit, and the multiple electric cylinders 3 are synchronously controlled to drive the movable plate 2 to move vertically. The gas meter to be tested is placed on the top of the base block 5. By rotating the rotating shaft 62, the threaded structure of the rotating shaft 62 drives the movable blocks that are threaded with it to move closer or further apart. Thus, the clamping plates 73 and rubber pads 74 at the top of each movable block clamp and fix the two sides of the gas meter. At the same time, the two movable blocks move synchronously to push the gas meter to the center position. Then, the two hydraulic cylinders 72 are synchronously controlled so that their moving ends drive the other two clamping plates 73 and rubber pads 74 to clamp and fix the other two sides of the gas meter. The other two sides of the gas meter are clamped and positioned. Through the synchronous adjustment process of the four clamping plates 73, the gas meter is always located in the center position at the top of the base block 5, which facilitates the testing process.

[0022] The working principle of this utility model is as follows: Multiple electric cylinders 3 are externally connected to one end of the same control circuit. The multiple electric cylinders 3 are synchronously controlled to drive the movable plate 2 to move vertically. The gas meter to be tested is placed on the top of the base block 5. By rotating the rotating shaft 62, the threaded structure of the rotating shaft 62 drives the movable blocks that are threaded with it to move closer or further apart. Thus, the clamping plates 73 and rubber pads 74 at the top of each movable block clamp and fix the two sides of the gas meter. At the same time, the two movable blocks move synchronously to push the gas meter to the center position. Then, the two hydraulic cylinders 72 are synchronously controlled to drive the other two clamping plates 73 and rubber pads 74 to clamp and fix the other two sides of the gas meter. The other two sides of the gas meter are clamped and positioned. Through the synchronous adjustment process of the four clamping plates 73, the gas meter is always located in the center position at the top of the base block 5, which facilitates the testing process.
