Detailed Description

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 contents of the present application.

Example one

Referring to fig. 1 and 2, a cross-sectional configuration of a plug 100 mounted to a valve 104 is shown. The plug 100 is mounted inside the valve 104. The air valve 104 is of a conventional air valve 104 structure, the air valve 104 comprises an air valve core 103, the air valve core 103 and an air valve wall form an air valve, the air valve core 103 of the air valve 104 is opened only when the tire is inflated, and air pressure in the tire acts on the air valve 104 after the inflation is finished so as to keep the air valve 104 in a closed state. A part of the plug 100 is disposed inside the valve 104, a cavity 114 for accommodating the valve pin 105 is disposed inside the plug 100, and the other part of the plug 100 is disposed outside the valve 104. The valve 104 may be used as a tire for a bicycle, electric vehicle, automobile, motorcycle, tricycle, or other common vehicle.

Referring to fig. 2 and 3, the plug 100 includes a sealing portion 112 and a detachable portion 102. The whole sealing portion 112 is integrally disposed inside the valve 104, and a screw structure 113 is disposed on the outer peripheral side of the sealing portion 112, and the screw structure 113 can play a role of reinforcing fixation when being connected with the inner wall of the valve 104. In a preferred embodiment, an internal thread structure may be provided on the inner wall of the valve 104 at a position corresponding to the sealing portion, and the internal thread structure engages with the thread 113 on the sealing portion when the sealing portion 112 is installed in the valve, so that the plug 100 is more firmly fixed. The detachable portion 102 of the plug 100 of the valve is provided at the outermost portion of the valve to facilitate the external detachment.

The plug 100 includes a removal portion 102 to allow the plug 100 to be installed into the opening 110 of the valve 104 or removed from the opening 110 of the valve 104. The detachable portion 102 is a conical protrusion protruding from the valve 104, the conical protrusion is higher than the valve opening 110, three grooves 108 are formed on the conical protrusion, and the grooves 108 are used for accommodating the detachable portion of the wrench 128 during detachment. The wrench 28 is able to rotate the plug 100 through the recess 108 to remove the plug 100 from the valve 104 or to attach the valve 104.

The grooves 108 on the dismounting part 102 are uniformly distributed by taking the center of the cone of the dismounting part as the center, the center of the groove 108 is in an arc shape, and the opening of the groove 108 is gradually enlarged from the periphery of the center until the edge of the groove is communicated with the edge of the conical projection 102. This facilitates access to the recess 108 by the removal portion of the removal wrench 128, making it easier and more convenient for the user to use.

The plug 100 is completely accommodated inside the air nozzle 104, and the detachable part 102 is a conical structure, so that the plug cannot be detached by hand without a detaching tool, and the tire can be prevented from being deflated maliciously. Meanwhile, the air nozzle plug 100 is protected by the air nozzle 104, and compared with the existing external cap type air nozzle plug which is screwed on the air nozzle 104 through threads and is subjected to tension for a long time, the air nozzle plug is easy to age and crack due to the thin-wall plastic piece structure. In the air faucet plug 100, the air faucet is subjected to the compressive force of the air faucet inside, and the wall thickness of the built-in plug is large, so that the plug is not easy to crack even if the material is aged.

Referring to fig. 4 and 5, the plug 100 is disassembled 128 using a wrench. The wrench includes a rod portion 129, the rod portion 129 being a straight rod in the figures, and the wrench 128 may be a bent rod 128 such as an L-shaped rod instead of a straight rod. The shank of the wrench 128 is provided with a thread 127 for increasing muscle friction. The head end 118 of the rod 128 includes a post 116 protruding therefrom, and the post 116 is positioned to correspond to the groove 108 of the mounting portion 102 of the plug 100, such that the post 116 engages the groove 108 of the mounting portion 102. When the wrench 128 is used to disassemble or fasten the plug 100, the handle of the wrench 128 is rotated to drive the plug 100 to rotate through the disassembling and assembling column 116, so that the thread 1113 of the plug 100 is fastened or released with the inner wall of the valve 104. In fig. 5, the disassembling and assembling post 116 is disposed on one end of the wrench 128, and those skilled in the art can also think that the disassembling and assembling post 116 can be disposed on both ends of the disassembling and assembling wrench 128, so that either end can be disassembled and assembled for use more conveniently.

Example two

Referring to fig. 6, the present embodiment is different from the first embodiment in the structure of the detachable portion of the plug 100. The plug attaching and detaching portion includes at least one attaching and detaching post 120 protruding from the air tap. When a dismounting column 120 is arranged, the dismounting column 120 is arranged at one side of the center of the plug, and a groove 122 capable of accommodating the dismounting column is arranged on the dismounting wrench head end 118. When two dismounting columns 120 are provided, the dismounting columns 120 are arranged at positions which are symmetrical about the center of the plug 100, and the corresponding grooves 122 are formed in the dismounting plate 118, so that the dismounting columns 120 can be inserted into the grooves 122 to rotate the plug. Similarly, the grooves 122 on the wrench 128 for attaching and detaching the plug 100 can be disposed on both ends of the wrench. Three mounting and removal posts 120 and corresponding three grooves 122 are preferably provided as shown in fig. 6.

EXAMPLE III

The difference between this embodiment and the first embodiment is the structure of the detachable portion of the plug 100. The plug dismounting part comprises a rib 124 extending upwards from the plug, and the rib 124 is small in height and cannot be directly dismounted by hands. The corresponding wrench head end 118 for removing the plug includes a removal groove 126 for receiving the ribs. The recess 126 of the wrench head end 118 extends through the entire wrench head end 118, and the recess 126 may be provided with a plurality of recesses, for example, two criss-crossing recesses provided on the wrench head end.
