air valve connector

Abstract

This invention provides a valve connector, including a body, a connector rotatably inserted through the body, and a connector assembly disposed at the end of the connector. The connector assembly includes a cover, a first anti-leak ring, and a spacer disposed therebetween, wherein the spacer separates the first anti-leak ring from the cover. Therefore, when the connector rotates relative to the body, the first anti-leak ring is prevented from being driven by the cover, thereby preventing the first anti-leak ring from rubbing against the valve core, preventing the valve core from unintentionally loosening relative to the valve body, and improving the sealing reliability and operational stability after inflation.

Description

air valve connector Technical Field

[0001] This invention relates to a valve connector, particularly a valve connector that reduces or avoids frictional action of the first anti-leak ring on the valve core, thereby preventing the valve core from unexpectedly loosening after inflation. Prior Technology

[0002] Presta valves used in tubeless bicycle systems typically employ a detachable valve core structure, allowing users to remove the valve core and fill it with sealant. These valve cores are usually externally threaded into a threaded hole in the valve body to create an airtight seal.

[0003] However, in actual use, when the user detaches the French valve from the valve connector after inflation, the first anti-leak ring inside the valve connector will contact the outer surface of the valve core. The friction generated by this contact will cause friction to drive the valve core. When the torque generated by this friction is greater than the locking force between the valve core and the valve body, the valve core may unexpectedly twist out or loosen relative to the valve body, resulting in air leakage immediately after inflation.

[0004] Therefore, the existing technology still has a defect: in French valve systems with detachable valve cores, there is a lack of an effective structure to prevent the valve connector from rubbing against the valve core during disassembly, causing the valve core to loosen and affecting the sealing reliability after inflation. Summary of the Invention

[0005] This invention provides an air valve connector, the main purpose of which is to prevent the air valve core from being driven by the cover when the air valve connector rotates by setting an isolation member between the air valve and the cover, thereby preventing the air valve core from being unexpectedly loosened relative to the air valve body, and improving the sealing reliability and usage stability after inflation.

[0006] To achieve the above objectives, the novel air nozzle connector includes: a body, a connector rotatably disposed within the body, and a first connecting assembly disposed at a first end of the connector. The connector has a through hole and a threaded hole for screwing into the air nozzle body of a French-type air nozzle. The first connecting assembly includes a first cover, a first leak-proof ring, and a spacer disposed therebetween, wherein the spacer is configured to separate the first leak-proof ring from the first cover, so as to prevent the first leak-proof ring from being driven by the first cover when the connector rotates relative to the body.

[0007] In one embodiment, the separator is annular, with a limiting portion and a receiving portion formed on its inner circumferential surface. The leak-proof ring is disposed within the receiving portion and is simultaneously subject to axial and radial positioning constraints to ensure that the leak-proof ring is stably positioned during use and does not rotate with the cover. Furthermore, the first cover and the connecting member can be detachably connected through corresponding threaded portions, facilitating assembly and maintenance.

[0008] In one embodiment, the valve connector further includes a stop member and a second connecting assembly disposed at the second end of the connector. The stop member is movably disposed within the through hole of the connector and has a stop top for abutting the valve screw of the French valve; the second connecting assembly includes a second cover and a second anti-leak ring, so that the valve connector can maintain a good airtight effect during inflation operation and improve the overall ease of use.

[0009] In summary, the novel air nozzle connector, through the inclusion of an isolating element, effectively blocks the driving relationship between the leak-proof ring and the cover, preventing the air nozzle core from loosening and leaking due to connector rotation after inflation. This not only improves upon the shortcomings of existing technologies but also offers advantages such as simple structure, easy assembly, and high practicality. To make the above features and effects clearer, specific embodiments will be further described below with reference to the accompanying drawings. Simple Explanation of the Diagram

[0010] Figure 1 is a three-dimensional appearance schematic diagram of an air nozzle connector according to an embodiment of the present invention. Figure 2 is a three-dimensional exploded view of the air nozzle connector shown in Figure 1. Figure 3 is a cross-sectional schematic diagram of the valve connector shown in Figure 1, showing the connection of the valve connector to the French valve. Implementation

[0011] Please refer to Figures 1 to 3. This invention provides an air nozzle connector, the main structure of which includes a body 10, a connector 20, and a first connector group 30, and may optionally include a stop member 40 and a second connector group 50.

[0012] The body 10 has a through hole 11 and an air passage 12 communicating with the through hole 11. Understandably, the body 10 can be connected to an inflation device or air hose, communicating with the air passage 12 so that compressed air supplied by an external air source can be introduced into the nozzle connector via the air passage 12. A connector 20 is rotatably inserted into the through hole 11 and has a first end 21 and a second end 22 exposed outside the through hole 11. A through hole 23 is formed inside the connector 20, communicating with the through hole 11, and a threaded hole 24 is formed at the first end 21, allowing compressed air to enter the through hole 23 via the air passage 12 and the through hole 11. The threaded hole 24 is configured to be detachably screwed onto the outer circumferential thread ET of the nozzle body VB of the French nozzle FV, allowing a reliable connection between the nozzle connector and the French nozzle FV.

[0013] The first connecting assembly 30 is disposed at the first end 21 of the connecting member 20, including a first cover 31 connected to the first end 21, a first leak-proof ring 32 disposed between the first end 21 and the first cover 31, and a separator 33 disposed between the first cover 31 and the first leak-proof ring 32. The separator 33 is configured to separate the first leak-proof ring 32 from the first cover 31, so that when the connecting member 20 rotates relative to the body 10, the first leak-proof ring 32 will not be driven by the rotation of the first cover 31, thereby preventing the first leak-proof ring 32 from frictionally driving the nozzle core VC and preventing the nozzle core VC from detaching from the nozzle body VB and leaking air.

[0014] In this embodiment, the isolator 33 is annular. Further, the isolator 33 has a limiting portion 331 and a receiving portion 332 formed on its inner circumferential surface. The limiting portion 331 extends inward from the inner circumferential surface of the isolator 33, while the receiving portion 332 is adjacent to the limiting portion 331. The first leak-proof ring 32 is disposed within the receiving portion 332, with its axial ends abutting against the limiting portion 331 and the first end 21 of the connector 20, respectively. Simultaneously, the radially outer side of the first leak-proof ring 32 abuts against the receiving portion 332, while its radially inner side abuts against the junction of the nozzle body VB and the nozzle core VC of the French nozzle FV. Thus, the first leak-proof ring 32 is positioned and restricted both axially and radially, allowing it to be stably disposed in a predetermined position. Furthermore, when the connector 20 rotates relative to the body 10, the first leak-proof ring 32 will not be moved by the rotation of the first cover 31.

[0015] In one specific embodiment, the connector 20 has a first external thread 211 on the outer peripheral surface of the first end 21, while the first cover 31 has a first internal thread 311 on the inner peripheral surface. The first internal thread 311 can be detachably screwed to the first external thread 211, so that the first cover 31 can be stably installed on the connector 20, and at the same time, it is convenient to disassemble and maintain.

[0016] Furthermore, the valve connector also includes a stop member 40 and a second connecting assembly 50. The stop member 40 is movably disposed within the through hole 23 and has a stop top 41 adapted to abut against the valve screw VN of the French valve FV, so that the valve core VC can be opened during inflation operation.

[0017] The second connecting assembly 50 is disposed at the second end 22 of the connecting member 20, including a second cover 51 connected to the second end 22, and a second anti-leak ring 52 disposed within the through hole 23 and adjacent to the second end 22. The second anti-leak ring 52 is configured to abut against the abutment member 40 to maintain a good airtight effect on the air nozzle connector during inflation. It is understood that both the first anti-leak ring 32 and the second anti-leak ring 52 in this embodiment can be made of an elastic deformable material.

[0018] In one specific embodiment, the connector 20 has a second external thread 221 on the outer peripheral surface of the second end 22, and the second cover 51 has a second internal thread 511 on the inner peripheral surface. The second internal thread 511 can be detachably screwed to the second external thread 221, so that the second cover 51 can be installed on the second end 22 of the connector 20.

[0019] In summary, the novel air nozzle connector, by providing an isolation member 33 between the first anti-leak ring 32 and the first cover 31, can effectively block the driving relationship between the first anti-leak ring 32 and the first cover 31, and avoid the problem of air leakage due to the rotation of the connector 20 after the air nozzle core VC is inflated, thereby improving the overall reliability and practical value.
