Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy wheel hubs, in particular to an aluminum alloy wheel hub which is anti-deflation. Background Art

[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile and is mounted on an axle. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material.

[0003] After extensive searching, a wheel hub with application number CN201921603890.X was found, including a wheel center, a rim, and multiple spokes spaced between the wheel center and the rim. The thickness of the spokes gradually decreases from the wheel center to the rim. A window that penetrates the thickness of the spoke is provided at the center of the spoke near one end of the rim. A strip groove connecting the window and the wheel center is provided on the front of the spoke. The portion of the spoke corresponding to the bottom of the strip groove forms a reinforcement rib of the corresponding spoke. Most wheel hubs lack a structure to protect the valve core, causing the valve core cap to fall off during vehicle driving, and then some small mud and sand enter the valve core, causing the tire to slowly deflate during driving, affecting safe driving. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0007] By adopting the above technical solution, the movable plate is pulled toward the outside of the plate body until the plug on the movable plate can be connected to the reinforcement frame. At this time, the plate body and the baffle are just located on the outside of the valve core. Then, the baffle is pressed against the inner wall of the wheel hub body by the spring, and the baffle is tightly against the valve core cap, which effectively prevents the valve core cap from loosening, protects the valve core, and improves the driving safety of the car.

[0008] In a preferred example, the present invention can be further configured as follows: the reinforcement frame is integrally formed with the hub body, and the reinforcement frame is located outside the insertion hole.

[0010] In a preferred example, the utility model can be further configured as follows: two springs are vertically symmetrical about a vertical center plane of the baffle, and the springs are arranged inside the plate body.

[0011] In a preferred example, the utility model can be further configured as follows: a plurality of positioning rods are arranged in groups of two, and are arranged in two groups, and the two groups of positioning rods are respectively located on both sides of the baffle.

[0012] In a preferred example, the utility model can be further configured as follows: the movable plates are provided in two numbers, and the two movable plates are respectively located at two sides of the plate body.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] In the utility model, the movable plate is pulled toward the outside of the plate body until the plug on the movable plate can be connected with the reinforcing frame. At this time, the plate body and the baffle are just located outside the valve core, and then the baffle is pressed against the inner wall of the wheel hub body under the pressure of the spring, and the baffle is tightly against the valve core cap, which effectively prevents the valve core cap from loosening, protects the valve core, and improves the driving safety of the car.
