[0029] Example

[0030] See also Figure 1 , Figure 2 and Figure 3 , the tire valve stem reinforcement rubber member provided in an embodiment of the present invention comprises:

[0031] A hollow threaded tube 1 and a rubber body 4, wherein the hollow threaded tube 1 is mounted and fixed on the alignment protrusion 2, the alignment protrusion 2 is arranged on the rubber body 4, and the alignment protrusion 2 and the rubber body 4 are integrally formed, and a clamping groove 3 is formed between the lower end of the alignment protrusion 2 and the upper end of the rubber body 4;

[0032] A hollow groove 6 is formed inside the hollow threaded tube 1, and a one-way component 5 is installed in the hollow groove 6 at the end portion after the bottom end of the hollow threaded tube 1 passes through the rubber body 4; the one-way component 5 has a one-way valve function; it can ensure that the tire has a one-way ventilation effect when inflating, and at the same time, it can avoid that after the tire is inflated, the inflated tire has good air tightness and is not easy to leak;

[0033] In the embodiment of the present invention, when the tire valve reinforcing rubber part is used, after the rubber part body 4 is installed at the inflation port position of the tire, the alignment protrusion 2 provided on the rubber part body 4 fits with the inner wall position of the inflation port, and the clamping groove 3 formed between the alignment protrusion 2 and the rubber part body 4 can clamp and fix the alignment protrusion 2 and the inner wall of the inflation port on both sides. Therefore, when the tire valve reinforcing rubber part is installed inside the early tire or when the tire moves violently in the later stage, the entire tire valve reinforcing rubber part and the inner wall of the tire inflation port will not shake, thereby enhancing the firmness of the installation between the entire tire valve reinforcing rubber part and the inner wall of the tire inflation port;

[0034] The one-way component 5 installed at the same time has a one-way valve function, so it can ensure that air is inflated into the tire through the position of the hollow threaded tube 1, and at the same time ensure the air tightness of the entire tire to prevent the tire from leaking;

[0035] See also Figure 3 and Figure 4 In one embodiment of the present invention, the one-way component 5 includes a hole plug 7, a one-way plug 11 and a baffle 12. The hole plug 7 is slidably installed inside the hollow groove 6, and an opening 8 is opened on the surface of the hole plug 7; a movable rod 9 is provided at the middle lower end of the hole plug 7, a partition 10 is installed inside the hollow groove 6, and a one-way plug 11 is installed at the end portion after the bottom end of the movable rod 9 passes through the partition 10. The one-way plug 11 is movably installed inside the hollow groove 6, and a baffle 12 is installed at the bottom end of the one-way plug 11;

[0036] In the embodiment of the present invention, when the tire is inflated through the one-way component 5, for example, the gas flows inside the hollow groove 6, first passes through the openings 8 opened on both sides of the opening plug 7, and when the air pressure is too high, it pushes the opening plug 7 to slide and move; at the same time, the high-pressure airflow passes through the partition 10 and enters the one-way plug 11, and finally enters the tire through the one-way plug 11;

[0037] In one embodiment of the present invention, the bottom end of the movable rod 9 is inserted into the part of the one-way plug 11 and fixed by the bracket 13, and a gap is formed between adjacent brackets 13; at the same time, a piston 14 is movable inside the one-way plug 11, and the upper end of the piston 14 is connected to the bracket 13 through a compression spring 15;

[0038] In the embodiment of the present invention, when the introduced gas passes through the partition 10 and enters the inside of the one-way plug 11, it will push the piston 14 installed inside the one-way plug 11 to slide and displace, and finally a gap will be generated between the outer side of the piston 14 and the inner wall of the one-way plug 11 for the passage of air flow; and when the air supply is stopped, the recoil air pressure generated inside the tire and the compression spring 15 that generates elastic force with the deformation will push the piston 14 to return to the initial state, causing the inside of the one-way plug 11 to be blocked again to prevent gas leakage; at the same time, the high-pressure gas generated inside the tire will also rebound to the baffle 12, further pushing the one-way plug 11 to displace inside the hollow groove 6, and causing the baffle 12 to block the hollow groove 6 and the gap inside the tire;

[0039] The above-mentioned method for installing the tire valve reinforcing rubber member comprises the following steps:

[0040] S1. Install the one-way component 5 in the hollow groove 6 opened in the hollow threaded tube 1. When installing the one-way component 5, the upper end of the movable rod 9 is inserted into the hollow groove 6 through the partition 10 and fixed in the middle position with the hole plug 7;

[0041] S2, after the one-way component 5 is installed at the bottom end of the hollow groove 6, the entire rubber body 4 with the one-way component 5 is then aligned and fitted on the inner wall at the tire notch position, and the tire notch position is aligned and pressed and fixed by the clamping groove 3 formed between the alignment protrusion 2 and the rubber body 4;
