Description

Technical Field

[0001] This invention relates to the technical field of bicycle valves, and more particularly to a valve assembly that is mounted on the rim of a tire and has an adjustable height. Background Technology

[0002] In recent years, bicycles have become an increasingly popular recreational and transportation tool, and cycling has become a very popular competitive sport for both amateur enthusiasts and professionals. Currently, the bicycle tire industry designs rims with different functions to meet various needs. For example, rims are designed with a longer radial length and a narrower axial width to reduce wind resistance on the tires when the bicycle is traveling at high speeds, thus maintaining tire rotation speed. Summary of the Invention

[0003] The present invention is an adjustable height valve assembly, the main purpose of which is to adjust the height of the valve assembly on the valve according to different tires.

[0004] To achieve the above objectives and effects, the present invention provides an adjustable height air nozzle assembly, comprising: a base body, internally for locking the air nozzle valve stem, an externally connected air nozzle connector, the air nozzle connector being connected to the air nozzle, and the inner surface of the air nozzle connector and the outer surface of the air nozzle valve stem respectively having a first locking section and a second locking section; an adapter, locked inside the air nozzle connector, the outer surface of the adapter having a third locking section that locks with the first locking section, and the inner surface having a fourth locking section that locks with the second locking section; the adapter allows the base body and the air nozzle valve stem to be locked together, and the height of the base body on the air nozzle is adjusted by the relative locking stroke of the base body, the adapter, and the air nozzle valve stem.

[0005] The valve stem has a first air intake space, the valve connector has a second air intake space, and the adapter has a third air intake space. The first air intake space, the second air intake space, and the third air intake space are interconnected.

[0006] The gas generated by the valve stem enters the tire through the second air intake space of the valve stem connector, the third air intake space of the adapter, and the first air intake space of the valve stem.

[0007] The base consists of a first base and a second base. The first base has a through hole for the valve stem to pass through into the base.

[0008] The first base has a locking device at the through hole. When the valve stem is inserted into the base, the locking device locks the valve stem, so that the valve stem is firmly attached to the base. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0016] Please see Figures 1 to 5 As shown, the present invention is an adjustable height air nozzle assembly, comprising: The valve stem 1 is located on the tire 2 of the bicycle. The outer surface of the valve stem 1 has a second locking section 10, and the interior has a first air intake space 11.

[0017] The base 3 is composed of a first base 30 and a second base 31. The first base 30 is provided with a through hole 300 for the air valve stem 1 to pass through into the interior of the base 3. A locking member 32 is provided at the through hole 300 of the first base 30. When the air valve stem 1 passes through the interior of the base 3, the air valve stem 1 is locked by the locking member 32, so that the air valve stem 1 is firmly locked on the base 3. The second base 31 has a connecting part 310 and connects to the air valve connector 33 through the connecting part 310. The air valve connector 33 is equipped with an air valve 5. The inner surface and interior of the air valve connector 33 are respectively provided with a first locking section 330 and a second air intake space 331.

[0018] The adapter 4 has a third air intake space 42 inside and is locked inside the air nozzle connector 33. The outer surface of the adapter 4 has a third locking section 40 corresponding to the first locking section 330, and the inner surface has a fourth locking section 41 corresponding to the second locking section 10. In this embodiment, the first air intake space 11, the second air intake space 331, and the third air intake space 42 are interconnected. In terms of assembly, the adapter 4 is placed inside the valve connector 33 of the seat body 3 and is locked to the first locking section 330 of the valve connector 33 by the third locking section 40. The valve stem 1 passes through the through hole 300 of the first base 30 into the seat body 3 and is locked to the fourth locking section 41 of the adapter 4 by the second locking section 10, so that the seat body 3 is locked on the wheel rim 20 of the tire 2. The gas generated by the valve 5 can enter the bicycle tire 2 through the second air intake space 331 of the valve connector 33, the third air intake space 42 of the adapter 4 and the first air intake space 11 of the valve stem 1, so as to achieve the effect of inflating the tire 2.

[0019] In implementation, the present invention, by tightening the air nozzle connector 33, makes the third locking section 40 and the fourth locking section 41 of the adapter 4 completely lock with the first locking section 330 of the air nozzle connector 33 and the second locking section 10 of the air nozzle valve stem 1, respectively, so that the seat 3 and the air nozzle valve stem 1 are in a locked state (e.g., Figure 3 As shown), at this time, the seat 3 is adjusted to a lower position on the air nozzle 5, and the distance between the seat 3 and the wheel rim 20 is relatively close. Conversely, by loosening the air nozzle connector 33, the third locking section 40 and the fourth locking section 41 of the adapter 4 are partially locked with the first locking section 330 of the air nozzle connector 33 and the second locking section 10 of the air nozzle valve stem 1, respectively, so that the seat 3 and the air nozzle valve stem 1 are in a loose-locked state (as shown). Figure 4 As shown in the diagram, the seat 3 is adjusted to a higher position on the valve stem 5, and the distance between the seat 3 and the wheel rim 20 is greater. Accordingly, the valve assembly 6 of the present invention uses the adapter 4 to lock the seat 3 and the valve stem 1 together. By adjusting the relative locking stroke of the seat 3, the adapter 4, and the valve stem 1, the height of the seat 3 on the valve stem 5 can be adjusted to accommodate the installation of different tires 2 and increase practicality.

[0020] The embodiments described above are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention, or reasonable combinations of features and solutions from various embodiments, are all within the scope of protection of the present invention.
