Description

Transfer pressurizing air nozzle structure for bicycle tire

This creation is about a kind of transfer valve, especially a kind of transfer pressure nozzle structure for bicycle tires.

By the way, the current types of bicycle tires can be divided into two types: "inner tube" and "bicycle tire". Regardless of whether the bicycle system adopts the form of "inner tube" or "tubeless", it needs to be filled with gas through the air nozzle. .

In the structural design of the aforementioned tubeless wheel set, because there is no need to install an inner tube, its air nozzle is directly installed on the double-layer rim. The double-layer rim is provided with corresponding inner and outer assembly holes. The nozzle includes an air nozzle body and an airtight body arranged at the tail end of the air nozzle body. The outer circumference of the air nozzle body is provided with a threaded part. The outer diameter of the airtight body is larger than the aperture of the outer assembly hole. During installation, the air nozzle body passes through the outer assembly hole and the inner assembly hole in sequence, and then a nut and the threaded part of the outer circumference of the air nozzle body are screwed and locked to make the airtight body abut against the The outer side of the outer assembling hole is used to close the outer assembling hole to achieve the sealing effect.

However, the air nozzle of the general tubeless wheel set can withstand limited air pressure. Therefore, when the tubeless tire is a high-pressure tire, it is often impossible to inflate the tire pressure to a predetermined high pressure, that is, it is not suitable for high-pressure tires, causing cycling People’s troubles and affect the safety of bicycle driving.

In view of the above-mentioned shortcomings of general tubeless air nozzles, the creator of this creation is based on the idea of thinking and creation. After many discussions and trial samples, as well as many revisions and improvements, he launched this creation.

This creation provides a transfer pressure air nozzle structure for bicycle tires, including: a valve tube, one end is provided with an internal thread part and an air outlet, the opposite end is provided with a first joint part and an air inlet, the internal thread At least one sealing ring is provided on the part, and a connecting part is provided between the air outlet and the air inlet to communicate; a valve core is provided with a second joint part at one end, a sealing ring sleeve is assembled in the middle section of the outer peripheral surface, and the center passes through A movable valve stem is provided, the valve core is installed in the communicating part of the valve tube, the second joint part of the valve core and the first joint part of the valve tube are combined with each other, and the stop ring of the valve core is forced Abutting against the inner wall of the communicating portion of the valve tube to form a sealing effect; and a cover body provided with a third coupling portion, so that the third coupling portion and the first coupling portion of the valve tube are coupled to each other, and the cover is provided It is closed on the air inlet of the valve tube.

The main purpose of this creation of the transfer pressure air nozzle structure for bicycle tires is that the transfer pressure air nozzle is used to connect to the air nozzle of the bicycle tire wheel assembly to form a double air stop effect so that it can be smoothly transferred. The tire pressure is pumped to a predetermined high pressure, which is suitable for high-pressure tires.

One end of the valve core 20 is provided with a second coupling portion 21, a sealing ring sleeve 22 is assembled in the middle of the outer peripheral surface, and a movable displacement valve stem 23 is penetrated in the center. The second coupling portion 21 is an external thread. The valve core 20 is installed in the communicating portion 16 of the valve tube 10, the second coupling portion 21 of the valve core 20 and the first coupling portion 13 of the valve tube 10 are combined with each other, and the sealing ring sleeve 22 of the valve core 20 is pressed against The bearing portion 161 of the inner wall of the communicating portion 16 of the valve tube 10 forms a sealing effect.

The cover 30 is provided with a third coupling portion 31, which is an external thread, so that the third coupling portion 31 and the first coupling portion 13 of the valve tube 10 are coupled to each other, so that the cover 30 covers The air inlet 14 provided in the valve tube 10 is closed.

When the transfer pressurizing air nozzle 1 is used, as shown in the fourth figure, the transfer pressurizing air nozzle 1 is assembled and connected to the air nozzle 21 of the bicycle tire wheel assembly 2, and the outer peripheral surface of the air nozzle 21 is provided with an outer surface. The threaded portion 211 is used for screwing and combining the internal threaded portion 11 of the valve tube 10 of the transfer pressurizing air nozzle 1, and the sealing ring 15 of the valve seat 10 makes the transfer pressurizing air nozzle 1 and the bicycle The air nozzle 21 of the tire wheel set 2 forms an anti-dense effect.

When inflating, as shown in the fifth figure, the cover 30 is removed, and the transfer pressurizing air nozzle 1 is used for the inflating nozzle (not shown in the figure) to be assembled for inflating, so that the air nozzle of the bicycle tire assembly 2 21 is pressed to open by the valve stem 23 of the valve core 20 of the transfer processing air nozzle 1, or the air nozzle 21 of the bicycle tire set 2 is opened by the air pressure of inflation, so that the valve of the transfer pressurized air nozzle 1 The core 20 and the air nozzle 21 of the bicycle tire set 2 are kept in a vented state, so that the inflation nozzle can perform an inflation action through the transfer pressurizing air nozzle 1 and the air nozzle 21 of the bicycle tire set 2.

When the inflation is completed, the inflator is separated from the transfer pressurized air nozzle 1, and the transfer pressurized air nozzle 1 and the air nozzle 21 of the bicycle tire wheel set 2 are used to form a double-layer air stop function to improve the performance The bicycle tire wheel set 2 can be inflated under high pressure under the pressure that it withstands.

Please also refer to the sixth figure of another embodiment, in which, one end of the valve tube 10 is provided with an external thread portion 18, which is locked and fixed on the air nozzle 21 of the inner tube wheel set 2, by The design of the external thread portion 18 provides that the user can use it on the air nozzle 21 of the inner tube wheel set 2 to achieve a multi-purpose effect.

From the structure of the above specific embodiment, the following benefits can be obtained:

The transfer pressurizing air nozzle structure for bicycle tires of this invention is used to connect the transfer pressurizing air nozzle 1 to the air nozzle 21 of the bicycle tire wheel assembly 2 to form a double air stop effect, so that it can be smoothly transferred The tire pressure is pumped to a predetermined high pressure, which is suitable for high-pressure tires, avoiding troubles for cyclists and improving the safety of bicycle driving.
