BEST MODE FOR CARRYING OUT THE INVENTION

The technical solutions of the present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can understand the technical content of the present application.

Example 1

Referring to FIG. 1 and FIG. 2 , the sectional structure state of the plug 100 installed on the valve 104 is shown. The plug 100 is installed inside the valve 104 . The valve 104 is a conventional valve 104 structure, the valve 104 includes a valve core 103, the valve core 103 and the valve wall constitute a valve valve, and the valve core 103 of the valve 104 is only used when the tire is inflated. After the inflation is completed, the internal air pressure of the tire acts on the valve 104 to keep it in a closed state. A part of the plug 100 is disposed inside the valve 104 , a cavity 114 for accommodating the valve thimble 105 is disposed inside the plug 100 , and another part of the plug 100 is disposed outside the valve 104 . The valve 104 can be used for common vehicle tires such as bicycles, electric vehicles, automobiles, motorcycles, and tricycles.

2 and 3 , the plug 100 includes a sealing portion 112 and a dismounting portion 102 . The sealing portion 112 is integrally disposed inside the valve 104 , and the outer peripheral side of the sealing portion 112 is provided with a threaded structure 113 , which can strengthen and fix when connecting with the inner wall of the valve 104 . In a preferred solution, an inner thread structure may be provided on the inner wall of the valve 104 at a position corresponding to the sealing portion, and the inner thread structure engages with the thread 113 on the sealing portion when the sealing portion 112 is installed in the valve. The combination makes the plug fixing 100 more firmly. The detachable part 102 of the valve plug 100 is provided at the outermost part of the valve to facilitate external detachment.

The plug 100 includes a dismounting portion 102 for the plug 100 to be installed into or removed from the opening 110 of the valve 104 . The dismounting portion 102 is a conical protruding structure protruding from the outside of the valve 104 . The conical projection is higher than the valve opening 110 , and three conical structures are provided on the conical structure for dismounting and assembling. The groove 108 is used to accommodate the disassembly and assembly part of the wrench 128 during disassembly and assembly. The wrench 28 can rotate the plug 100 through the groove 108 , so that the plug 100 is removed from the valve 104 or the valve 104 is installed.

The grooves 108 on the disassembly part 102 are evenly distributed with the center of the cone of the disassembly part as the center, the center of the groove 108 is arc-shaped, and the opening of the groove 108 gradually expands from the outer periphery of the center to the edge of the groove. It communicates with the edge of the tapered protrusion 102 . In this way, it is convenient for the detachable part on the detachable wrench 128 to enter the groove 108 , so that the user can use it more easily and more conveniently.

The above-mentioned plug 100 is completely accommodated inside the air nozzle 104, and the disassembly and assembly portion 102 is a conical structure, which cannot be disassembled by hand without a disassembly and assembly tool, thus preventing malicious deflation of the tire. At the same time, the air nozzle plug 100 is protected by the air nozzle 104. Compared with the existing external cap-type air nozzle plug, it will be under tension for a long time when it is screwed on the air nozzle 104 through the thread. In addition, the thin-walled plastic part structure causes it to age. Easy to crack. On the other hand, the valve plug 100 of the present application is subjected to the compression force of the valve inside the air nozzle, and because the wall thickness of the built-in plug is large, it is not easy to crack even if the material is aged.

Referring to FIGS. 4 and 5 , the plug 100 is disassembled and assembled 128 using a wrench. The wrench includes a rod portion 129. In the figure, the rod portion 129 is a straight rod. In addition to the straight rod, the wrench 128 may also be a bent rod 128 such as an L-shaped rod. The body of the wrench 128 is provided with a pattern 127 for increasing muscle friction. The head end 118 of the rod portion 128 includes a disassembly column 116 protruding from the head end. The grooves 108 on the detachable part 102 can be engaged. When using the wrench 128 to disassemble or tighten the plug 100, turn the handle of the wrench 128 to drive the plug 100 to rotate through the disassembly column 116, so that the thread 1113 of the plug 100 is fastened or tightened to the inner wall of the valve 104. freed. In FIG. 5 , the dismounting column 116 is arranged on one head end of the wrench 128 . Those skilled in the art can imagine that the dismounting column 116 can also be arranged on both ends of the dismounting spanner 128 , so that any One end can be disassembled and used more convenient.

本发明的实施方式Embodiments of the present invention

Referring to FIG. 6 , the difference between this embodiment and the first embodiment is the structure of the disassembly and assembly portion of the plug 100 . The plug disassembly and assembly part includes at least one disassembly and assembly column 120 protruding from the air nozzle. When a dismounting post 120 is provided, the dismounting post 120 is installed at one side of the center of the plug, and the head end 118 of the dismounting wrench is provided with a groove 122 capable of accommodating the dismounting post. When two dismounting posts 120 are provided, the dismounting posts 120 are installed at positions symmetrical with respect to the center of the plug 100 , and the dismounting lever 118 is provided with corresponding grooves 122 to enable the dismounting posts 120 Insert into groove 122 to rotate the plug. Similarly, the grooves 122 on the wrench 128 for dismounting and assembling the plug 100 can be provided at both ends of the wrench at the same time. As shown in FIG. 6 , three dismounting columns 120 and three grooves 122 corresponding thereto are preferably provided.

本发明的实施方式Embodiments of the present invention

The difference between this embodiment and the first embodiment is the structure of the disassembly and assembly portion of the plug 100 . The plug disassembly and assembly part includes a rib 124 extending upward from the plug. The height of the rib 124 is too small and cannot be directly disassembled by hand. The corresponding wrench head end 118 for dismounting the plug includes a dismounting groove 126 for receiving the rib. The groove 126 on the head end 118 of the wrench runs through the whole head end 118 of the wrench, and the groove 126 can be provided with a plurality of grooves such as two crisscross grooves on the head end.
