Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamp testing fixtures, and in particular to a fixture for testing the locking status of clamps. Background Technology
[0002] A clamp tightening checker is a tool used to check whether a clamp is properly tightened. Clamps are commonly used in pipelines, machinery, and other fields to secure pipes, components, or other items. The tightening condition of the clamp directly affects its function and safety.
[0003] Existing technologies, such as the utility model patent with publication number CN203100644U, disclose a clamp testing tool. This patent uses a standard clamp and a self-made sleeve that are fixed to each other. The outer ring shape of the self-made sleeve matches the inner ring shape of the standard clamp, and the open end plane of the standard clamp overlaps with the center line of the self-made sleeve. The beneficial effect of this utility model is that it can greatly improve the speed and accuracy of clamp testing and significantly reduce the operating costs of enterprises.
[0004] The inventors discovered during use that existing gauges are not adjustable and can only adapt to the locking state of clamps of a specific specification. For clamps of different specifications or with slight dimensional variations, the gauges cannot effectively detect them, making it impossible to accurately determine whether all types of clamps have reached the correct locking state. Furthermore, when the standards or requirements for clamp locking states change, the gauges cannot be adjusted to adapt to the new standards, resulting in the inability to perform effective re-verification and testing. This limits the long-term use and scalability of the gauges. Utility Model Content

The screw is fixedly connected to the sliding plate. A threaded ring is threadedly connected to the arc surface of the screw. The threaded ring is rotatably connected to the right clamp.
[0007] The effect achieved by the above components is as follows: when it is necessary to adjust the distance between the left and right gauges, the threaded ring is rotated to move, the threaded ring drives the screw to move, the threaded ring slides on the right gauge, the screw slides on the inner wall of the auxiliary groove, the screw drives the slide plate to slide on the inner wall of the connecting groove, and the slide plate drives the slide rod to slide on the inner wall of the slide groove, thereby facilitating the adjustment of the distance between the left and right gauges.
[0008] Preferably, the arc surface of the threaded ring is provided with a plurality of slots, and the plurality of slots are evenly distributed on the threaded ring.
[0009] The effect achieved by the above components is that the groove can increase the friction between the hand and the threaded ring, preventing slippage when rotating the threaded ring.
[0010] Preferably, the slide bar has a circular cross-section, and the two slide bars are distributed on both sides of the screw.
[0011] The effect achieved by the above components is that the slide bar can limit the skateboard, prevent the skateboard from deviating during adjustment, and improve the stability of the skateboard.
[0012] Preferably, the upper surface of the skateboard has a plurality of scale grooves, which are divided into two groups, and the two groups of scale grooves are evenly distributed on both sides of the skateboard.
[0013] The effect achieved by the above components is that the scale groove can easily control the length of the adjustment, and it is convenient to control the distance between the left and right gauges when adjusting.
[0014] Preferably, the cross-section of the skateboard is rectangular, and the skateboard is made of stainless steel.
[0015] The effect achieved by the above components is that the stainless steel material can increase the lifespan of the skateboard and prevent it from rusting during use.
[0016] Compared with related technologies, the clamp locking status detection tool provided by this utility model has the following beneficial effects:
[0017] This invention provides a gauge for detecting the locking status of clamps. By incorporating an adjustment structure, it addresses the limitations of existing gauges which are not adjustable and can only accommodate clamps of a specific specification. Existing gauges are unable to effectively detect clamps of different specifications or with slight dimensional variations, making it impossible to accurately determine whether all types of clamps have achieved the correct locking status. Furthermore, when the standards or requirements for clamp locking status change, the gauge cannot be adjusted to adapt to the new standards, hindering effective re-verification and testing. This limits the long-term use and scalability of the gauge. This device allows for convenient and rapid adjustment of the gauge, and after adjustment, the gauge's testing specifications can be easily confirmed using the graduated grooves.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0025] Please see Figures 1 to 4 The present invention provides a clamp locking state detection tool, comprising: a right tool 2 and an adjustment structure 3. A left tool 1 is provided on one side of the right tool 2. The left tool 1 is connected to the right tool 2 by means of the adjustment structure 3. The adjustment structure 3 is provided on the side of the right tool 2 near the left tool 1.
[0026] In the embodiments of this utility model, please refer to Figures 1 to 4 The adjusting structure 3 includes a connecting block 303, which is fixedly connected to the right gauge 2. The inner wall of the connecting block 303 has a connecting groove 309, and a sliding plate 301 is slidably connected to the inner wall of the connecting groove 309. The inner wall of the right gauge 2 and the connecting block 303 has an auxiliary groove 310. The inner wall of the right gauge 2 and the connecting block 303 has two sliding grooves 308, and a sliding rod 305 is slidably connected to the inner wall of the sliding groove 308. The sliding rod 305 is fixedly connected to the sliding plate 301. The auxiliary groove 310 has a screw 304 slidably connected inside, and the screw 304 is fixedly connected to the sliding plate 301. The arc surface of the screw 304 is threadedly connected to a threaded ring 306, and the threaded ring 306 is rotatably connected to the right gauge 2. When it is necessary to adjust the distance between the left gauge 1 and the right gauge 2, the threaded ring 306 is rotated to move it. The threaded ring 306 drives the screw 304 to move, and the threaded ring 306 slides on the right gauge 2. The screw 304 slides on the inner wall of the auxiliary groove 310, and the screw 304 drives the slide plate 301 to slide on the inner wall of the connecting groove 309. The slide plate 301 drives the slide rod 305 to slide on the inner wall of the sliding groove 308, thus facilitating the adjustment of the distance between the left gauge 1 and the right gauge 2. The arc surface of the threaded ring 306 has several slots 307, which are evenly distributed on the threaded ring 306. The slots 307 can increase the friction between the hand and the threaded ring 306, preventing slippage when rotating the threaded ring 306. The slide rod 305 has a circular cross-section, and two slide rods 305 are distributed on both sides of the screw 304. The slide bar 305 can limit the sliding plate 301, preventing it from shifting during adjustment and improving its sliding stability. The upper surface of the sliding plate 301 has several graduated grooves 302, divided into two groups, evenly distributed on both sides of the sliding plate 301. The graduated grooves 302 facilitate control of the adjustment length, making it convenient to adjust the distance between the left and right gauges 1 and 2. The sliding plate 301 has a rectangular cross-section and is made of stainless steel. The stainless steel material increases the service life of the sliding plate 301 and prevents corrosion during use.
[0027] The working principle of the clamp locking status detection gauge provided by this utility model is as follows: When it is necessary to adjust the distance between the left gauge 1 and the right gauge 2, the threaded ring 306 is rotated to move, the threaded ring 306 drives the screw 304 to move, the threaded ring 306 slides on the right gauge 2, the screw 304 slides on the inner wall of the auxiliary groove 310, the screw 304 drives the slide plate 301 to slide on the inner wall of the connecting groove 309, and the slide plate 301 drives the slide rod 305 to slide on the inner wall of the sliding groove 308, thereby facilitating the adjustment of the distance between the left gauge 1 and the right gauge 2. The distance between the two gauges is adjustable. The groove 307 increases the friction between the hand and the threaded ring 306, preventing slippage when rotating the threaded ring 306. The slide bar 305 limits the slide plate 301, preventing it from shifting during adjustment and improving the stability of the slide plate 301. The scale groove 302 allows for easy control of the adjustment length, facilitating the adjustment of the distance between the left gauge 1 and the right gauge 2. The stainless steel material increases the service life of the slide plate 301 and prevents it from rusting during use.
