[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides a technical solution: a wheel assembly air inflator. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes: a base 1 and an air pump 2, with the air pump 2 connected to the base 1. The top two sides of the base 1 are evenly provided with slots 12, and the top of the base 1 is equipped with a limit mechanism 3.

[0025] The base 1 can support the wheel, and the air pump 2 is a common inflation device in the prior art, which can inflate the wheel.

[0026] The limiting mechanism 3 includes a turntable assembly 31. Both sides of the bottom of the turntable assembly 31 are connected to round arms 32. A pull rod 33 is sleeved on the outside of the round arms 32, and the other end of the pull rod 33 is connected to a retaining ring 35 through a hinge. The retaining ring 35 is slidably connected to the base 1.

[0027] The turntable assembly 31 can support and limit the wheel, the round arm 32 can support the pull rod 33, the pull rod 33 can pull the retaining ring 35 to move, and the retaining ring 35 can clamp and fix the wheel.

[0028] The retaining ring 35 is internally equipped with a locking mechanism 4, which includes a top cover 41. A locking arm 42 is mounted on the bottom of the top cover 41 and is inserted into the top of the retaining ring 35.

[0029] The top cover 41 can be lifted by the expanding wheel, the locking arm 42 can limit the retaining ring 35, and the spring 43 can drive the top cover 41 to return to its original position after movement.

[0030] The top of the base 1 is evenly provided with guide grooves 11. A guide block 36 is slidably connected inside the guide groove 11. The guide block 36 is connected to the retaining ring 35. The guide groove 11 and the guide block 36 can guide the retaining ring 35 to move linearly.

[0031] The bottom of the turntable assembly 31 is equipped with a seated bearing assembly 34, which is connected to the base 1. The seated bearing assembly 34 can support the top cover 41 to allow the turntable assembly 31 to rotate. The turntable assembly 31 includes a disc, and the top of the disc is evenly distributed with locking arms. The locking arms can be inserted into the bolt fixing holes inside the tire to fix the tire. The seated bearing assembly 34 includes a seated bearing, which is connected to the base 1. The top of the seated bearing is connected to a short shaft, which is connected to the turntable assembly 31.

[0032] A spring 43 is connected to the bottom of the top cover 41. The spring 43 is connected to the retaining ring 35. The spring 43 can drive the top cover 41 to return to its original position after the movement is completed. The retaining groove 12 is a square groove and is adapted to the locking arm 42. The retaining groove 12 can fix the position of the retaining ring 35 through the locking arm 42.

[0033] This scheme first places the wheel assembly on top of the turntable assembly 31, and inserts the top clamping arm of the turntable assembly 31 into the bolt connection hole on the outside of the wheel assembly. The wheel assembly is rotated, which in turn drives the pull rod 33 to drive the two retaining rings 35 to move relative to each other, clamping the outside of the wheel assembly. Then, the wheel assembly is inflated by the air pump 2 to complete the inflation operation of the wheel assembly.

[0034] When the wheel assembly is inflated, it expands. After expanding to the set state, it drives the top cover 41 to rise, which drives the locking arm 42 to disengage from the inside of the slot 12, thereby releasing the control of the retaining ring 35. At this time, the retaining ring 35 returns to its original position through the expanded wheel assembly. The operator can judge whether the wheel assembly has completed the inflation operation based on the state of the limiting mechanism 3.

[0035] When the wheel assembly is being inflated, the added limiting mechanism 3 can quickly fix and protect the wheel assembly, preventing it from bursting due to over-inflation and causing injury to the surrounding construction environment and workers. At the same time, the added locking mechanism 4, in conjunction with the slot 12, prevents the limiting mechanism 3 from retracting during movement and failing to properly fix the wheel assembly. Furthermore, the tension of the wheel assembly after it has fully expanded after inflation drives the locking mechanism 4 to move and release the restriction on the limiting mechanism 3. This allows the limiting mechanism 3 to return to its original position through the expanded wheel assembly, reminding workers that the wheel assembly has been fully inflated and preventing damage to the wheel assembly due to over-inflation.
