Description

Technical Field

[0001] This utility model relates to the field of tire locking technology, specifically to an automatic tire locking device. Background Technology

[0002] Tires are circular, elastic rubber rolling products mounted on vehicles or machinery. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures during driving, so they must have high load-bearing capacity, traction performance, and cushioning properties.

[0003] In existing technologies, tire locking mechanisms on the market generally rely on manual adjustment or hydraulic cylinders for thrust. However, these methods lack precision, and tires can shift during operation after being secured, significantly reducing work efficiency. Furthermore, most of these mechanisms are large in size, making them more cumbersome to use, leading to higher maintenance costs and reduced safety during operation. Therefore, we have introduced an automatic tire locking device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tire locking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tire locking device, comprising: a housing, a driven bevel gear, and a balance bracket;

[0006] The motor is installed inside the housing and is connected to the inner top of the housing by screws. The output end of the motor passes through the housing and is provided with a drive bevel gear. When the motor is started, it can drive the drive bevel gear to rotate.

[0007] The driven bevel gear meshes with the surface of the driving bevel gear at equal intervals. When driven, the driving bevel gear can drive the driven bevel gear to rotate. The driven bevel gear has a threaded rod on its side, and the threaded rod is fixedly connected to the driven bevel gear.

[0008] The balance bracket is located on the top of the housing, the driven bevel gears are equally spaced on the top of the housing, and the threaded rod extends into the interior of the balance bracket. The surface of the balance bracket is provided with a moving mechanism. The threaded block of the moving mechanism drives the concave frame, the telescopic fixed bracket and the tire retainer to move, so that the tire retainer moves to the side of the tire to form a fixed position.

[0009] Preferably, the moving mechanism includes bolt A, the threaded block is connected inside the balance bracket, the threaded block slides inside the balance bracket, bolt A is connected to one side of the concave frame, and one end of bolt A passes through the concave frame and the threaded block respectively. Bolt A allows the concave frame to move with the movement of the threaded block, which is convenient for use. The concave frame slides on the surface of the balance bracket, the telescopic fixing bracket is connected to the top of the concave frame, and the telescopic fixing bracket and the concave frame are welded together. The top of the telescopic fixing bracket is connected to a top plate, and the top plate and the telescopic fixing bracket are welded together. The tire holder is connected to the top of the top plate.

[0010] Preferably, a bolt B is connected between the top plate and the tire clamp. Bolt B can fix the tire clamp to the top of the top plate, which also makes it easier to disassemble, replace or repair the tire clamp.

[0011] Preferably, the surface of the concave frame is provided with a limiting groove for sliding bolt A. The limiting groove and the concave frame are integrally formed. The limiting groove allows bolt A to slide, thereby restricting the movement of the concave frame on the top of the balance support.

[0012] Preferably, the surface of the tire retainer is connected to an inclined portion. The inclined portion can better fix the tire, making the tire more secure and easier to use. The inclined portion and the tire retainer are integrally formed.

[0013] Preferably, there are three sets of driven bevel gears and three sets of balance brackets, and the three sets of balance brackets are welded to the outer shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model drives the active bevel gear to rotate through the output end of the motor, which in turn drives the driven bevel gear to rotate, which in turn drives the threaded rod to rotate inside the balance bracket. The threaded rod then drives the threaded block to move inside the balance bracket. Bolt A passes through the concave frame and the threaded block, and the threaded block can drive the concave frame, the telescopic fixed bracket, the top plate, and the tire clamp to move through bolt A. Thus, the three sets of tire clamps clamp the tire, achieving precise locking of the tire without the need for manual clamping, making it convenient to use.

[0015] With its compact size, reliable structure, and higher locking precision, it is suitable for various tire requirements, easy to operate, low in maintenance costs, and improves safety performance during operation. Attached Figure Description

[0024] Driven bevel gear 12, which meshes with the surface of driving bevel gear 4 at equal intervals, and a threaded rod 13 is provided on the side of the driven bevel gear 12;

[0025] The balance bracket 3 is located on the top of the housing 1. The driven bevel gears 12 are evenly spaced on the top of the housing 1, and the threaded rod 13 extends into the interior of the balance bracket 3. The surface of the balance bracket 3 is provided with a moving mechanism. The threaded block 14 of the moving mechanism drives the concave frame 8, the telescopic fixed bracket 5 and the tire retainer 7 to move so that the tire retainer 7 moves to the side of the tire to form a fixation.

[0026] The moving mechanism includes a bolt A10. The threaded block 14 is connected inside the balance bracket 3 and slides inside the balance bracket 3. The bolt A10 is connected to one side of the concave frame 8, and one end of the bolt A10 passes through the concave frame 8 and the threaded block 14 respectively. The bolt A10 allows the concave frame 8 to move with the movement of the threaded block 14, which is convenient for use. The concave frame 8 slides on the surface of the balance bracket 3. The telescopic fixing bracket 5 is connected to the top of the concave frame 8. The telescopic fixing bracket 5 and the concave frame 8 are welded together. The top of the telescopic fixing bracket 5 is connected to a top plate 6. The top plate 6 and the telescopic fixing bracket 5 are welded together. The tire clamp 7 is connected to the top of the top plate 6.

[0027] Bolt B9 connects the top plate 6 and the tire holder 7. Bolt B9 can fix the tire holder 7 to the top of the top plate 6, which also makes it easier to disassemble the tire holder 7 for replacement or maintenance.

[0028] The surface of the concave frame 8 is provided with a limiting groove 11 for sliding bolt A10. The limiting groove 11 and the concave frame 8 are integrally formed. The limiting groove 11 allows the bolt A10 to slide, thereby restricting the movement of the concave frame 8 on the top of the balance support 3.

[0029] The surface of the tire retainer 7 is connected to an inclined portion. The inclined portion can better fix the tire, making the tire more secure and easier to use. The inclined portion and the tire retainer 7 are integrally formed.

[0030] The number of driven bevel gears 12 is three sets, and the number of balance brackets 3 is three sets, and the three sets of balance brackets 3 are welded to the outer shell 1.

[0031] Specifically, during use, the motor 2 is started, and the output end of the motor 2 drives the active bevel gear 4 to rotate on the top of the housing 1. Under the rotation of the active bevel gear 4, the active bevel gear 4 can drive the driven bevel gear 12 to rotate. Under the rotation of the driven bevel gear 12, the threaded rod 13 can rotate inside the balance bracket 3. The external thread on the surface of the threaded rod 13 matches and engages with the internal thread inside the threaded block 14. Thus, the threaded rod 13 can drive the threaded block 14 to move inside the balance bracket 3. The bolt A10 passes through the concave frame 8 and the threaded block 14 respectively. The threaded block 14 can drive the concave frame 8, the telescopic fixed bracket 5, the top plate 6 and the tire clamp 7 to move through the bolt A10. Thus, the three sets of tire clamps 7 clamp the tire, achieving precise locking of the tire without manual operation, which is convenient for use.
