Description

Technical Field

[0001] This utility model belongs to the field of tire clamp technology, and in particular relates to a clamp for vehicle tire inspection. Background Technology

[0002] The background technology of vehicle tire inspection fixtures mainly involves tire inspection and maintenance, especially in places such as automobile repair, tire factories and vehicle inspection stations. As one of the important components of a vehicle, tires are directly related to driving safety. Therefore, regular tire inspection is crucial. In order to more effectively conduct a comprehensive inspection of tires, fixtures, as a special tool, play an important role.

[0003] However, existing vehicle tire inspection clamps are not easy to ensure that the clamp remains clamped after the tire is held in place. As the inspection proceeds, the tire may shake or fall off due to the loosening of the clamp, which in turn affects the accuracy of the inspection data. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp for vehicle tire testing. By setting a retraction mechanism, it solves the problem that existing vehicle tire testing clamps are not easy to ensure that the clamp remains clamped after the tire is clamped. As the test is carried out, the tire may shake or fall off due to the loosening of the clamp, which will affect the accuracy of the test data.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A vehicle tire inspection fixture includes a support frame with a rotating shaft rotatably connected to it. The rotating shaft is equipped with a locking mechanism and a clamping mechanism. The locking mechanism includes a threaded rod fixedly connected to the front side of the rotating shaft. A limit plate is fixedly connected to the end of the threaded rod. A movable block is provided on the side of the threaded rod away from the limit plate. A limit plate is provided on one side of the movable block. The threaded rod passes through the limit plate. A plurality of limit grooves are formed on the side of the limit plate near the movable block. A plurality of limit blocks adapted to the limit grooves are fixed on the side of the movable block near the limit plate. The clamping mechanism includes a plurality of fixing rings fixed to the outer wall of the rotating shaft.

[0007] Furthermore, each of the fixed rings is hinged to a connecting rod 1 on its outer wall. A support plate is hinged to the side of the connecting rod 1 away from the fixed ring. The sides of the support plates that are away from each other are in contact with the inner wall of the tire. A ring is rotatably connected to the outer wall of the movable block. Several connecting rods 2 are fixed to the outer wall of the ring. The sides of the several connecting rods 2 that are away from the ring are respectively hinged to several support plates.

[0008] Furthermore, a spring is fitted on the outer wall of the threaded rod, with one side of the spring fixedly connected to the limiting plate and the other side of the spring fixedly connected to the limiting plate.

[0009] Furthermore, a handle is fixedly connected to the outer side of the rotating shaft.

[0010] Furthermore, an electric telescopic rod is fixedly connected to the first support frame, and a second support frame is fixedly connected to the output shaft of the electric telescopic rod. Several support rollers are rotatably connected inside the second support frame, and the outer walls of the several support rollers are in contact with the tire.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting a locking mechanism, before the moving block is turned to clamp the tire, the limiting plate must be pulled to move it forward until the limiting block is disengaged from the limiting groove. During this process, the spring is compressed, undergoes elastic deformation, and generates elastic force. After clamping, the limiting plate is released. At this time, the spring releases its elastic force and pushes the limiting plate closer to the moving block until the limiting block is inserted into the limiting groove. This prevents the moving block from reversing and ensures that the clamp remains stable when clamping the tire. It is not easy to loosen and ensures that the clamp is always in a proper clamping state. This effectively prevents the tire from shaking or falling off during the inspection process due to the clamp loosening. It also ensures that the locking force does not decrease during long-term inspection and ensures the accuracy of the inspection data.

[0013] 2. By setting up a clamping mechanism, when it is necessary to clamp the tire, the moving block can be turned. At this time, the ring will move backward, thereby forcing the connecting rod two and the connecting rod one on the fixed ring to cooperate with each other, opening up several support plates until the tire is stably clamped. It can adapt to tires with different inner diameters, increase the adaptability of the device, ensure that the tire will not slip or become unstable during operation, and provide better control.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5 As shown, this utility model is a vehicle tire inspection clamp, including an L-shaped support frame 1. The support frame 1 has a rotating shaft 101, which is rotatably connected to the support frame 1. A handle 103 is fixedly connected to the outside of the rotating shaft 101. The rotating shaft 101 is provided with a locking mechanism 2 and a clamping mechanism 3. An electric telescopic rod 104 is fixedly connected to the support frame 1, and the electric telescopic rod 104 is located below the rotating shaft 101. A second support frame 105 is fixedly connected to the output shaft of the electric telescopic rod 104. Several support rollers 106 are rotatably connected inside the second support frame 105. A tire 102 is installed on the clamping mechanism 3. At this time, the outer walls of the several support rollers 106 are in contact with the tire 102.

[0024] The locking mechanism 2 includes a threaded rod 211 fixedly connected to the front side of the rotating shaft 101. A limiting plate 212 is fixedly connected to the end of the threaded rod 211. A moving block 213 is threadedly connected to the side of the threaded rod 211 away from the limiting plate 212. A limiting disk 214 is provided on the front side of the moving block 213. The threaded rod 211 passes through the limiting disk 214. Several limiting grooves 215 are provided on the side of the limiting disk 214 near the moving block 213. Several limiting blocks 216 are fixedly connected to the side of the moving block 213 near the limiting disk 214. The 6 is adapted to several limiting grooves 215 respectively. A spring 217 is sleeved on the outer wall of the threaded rod 211. One side of the spring 217 is fixedly connected to the limiting plate 214, and the other side of the spring 217 is fixedly connected to the limiting plate 212. By setting the locking mechanism 2, it can be ensured that the clamp remains stable when clamping the tire and is not easy to loosen. It ensures that the clamp is always in a proper clamping state, thereby effectively preventing the tire from shaking or falling off due to the loosening of the clamp during the inspection process, ensuring that the locking force does not decrease during long-term inspection, and ensuring the accuracy of the inspection data.

[0025] The clamping mechanism 3 includes two fixed rings 311 fixedly connected to the outer wall of the rotating shaft 101. Several connecting rods 312 are hinged to the outer walls of the two fixed rings 311. Several support plates 313 are hinged to the side of the connecting rods 312 away from the two fixed rings 311. The side of the support plates 313 away from each other is in contact with the inner wall of the tire 102. A ring 314 is rotatably connected to the outer wall of the moving block 213. Several connecting rods 315 are fixedly connected to the outer wall of the ring 314. The side of the connecting rods 315 away from the ring 314 is hinged to the support plates 313 respectively. By setting the clamping mechanism 3, it can adapt to tires 102 with different inner diameters, increase the adaptability of the device, ensure that the tire 102 will not slip or become unstable during operation, and provide better control.

[0026] A specific application of this embodiment is as follows: In use, the tire 102 to be tested is first inserted onto several support plates 313. When the tire 102 needs to be clamped, the moving block 213 can be turned. At this time, the ring 314 will move backward, thereby forcing the connecting rod 215 to cooperate with the connecting rod 312 on the fixed ring 311, opening the support plates 313 until the tire 102 is stably clamped. Before turning the moving block 213 to clamp the tire 102, the limiting plate 214 must be pulled forward until the limiting block 216 disengages from the limiting groove 215. During the process, the spring 217 is compressed, undergoes elastic deformation, and generates elastic force. After clamping is completed, the limiting plate 214 is released. At this time, the spring 217 releases its elastic force, pushing the limiting plate 214 closer to the moving block 213 until the limiting block 216 is inserted into the limiting groove 215 to prevent the moving block 213 from reversing. Then, the electric telescopic rod 104 is activated to extend it until the support roller 106 in the support frame 105 contacts the tire, providing additional support for the tire. After completing the above operations, the tire can be inspected. During inspection, the handle 103 can be turned as needed to adjust the angle of the tire 102.
