Description

Tire Inflator Core Remover Tool

The present invention relates to a disassembly tool, in particular to a tire inflation nozzle core removal tool.

When the valve core of the tire inflator is damaged and needs to be replaced or for routine maintenance, the valve core needs to be disassembled. Long-term use or external damage may cause the valve core to fail, resulting in unstable air pressure or air leakage. Therefore, regular inspection and replacement of the valve core helps ensure that the tire is properly inflated and ensures safe driving.

In the prior art, there is a core removal tool for removing the valve core inside the tire inflation nozzle. When the core removal tool is combined with the valve core, the inflation nozzle and the valve core are connected by a thread, and the front end of the valve core is equipped with a block and a push pin. The valve removal tool includes a rod, a head and a ball assembly. The rear end of the rod is for the operator to hold, and the head is arranged at the front end of the rod. The head has a slot, and the ball assembly is arranged inside. When actually using it, the operator extends the front end of the rod of the core removal tool into the inflation nozzle, so that the head contacts the valve core, the slot of the head and the block of the valve core are engaged with each other, and the ball assembly clamps and fixes the push pin. The valve core can be removed by rotating the core removal tool. However, the core removal tool with a ball assembly is complicated to manufacture and costly, and difficult to assemble; in addition, the ball assembly and the valve core ejector pin are both made of rigid materials, which are easily worn out over a long period of use, thereby reducing their service life.

In order to solve the above problems, it is necessary to develop more practical innovative structures to meet consumer needs. This is also the goal and direction that relevant industries should strive to develop. Therefore, the inventor of the present invention came up with the idea of creation. After many discussions and trial samples, as well as many revisions and improvements, the present invention was launched.

The present invention provides a tire inflation nozzle core removal tool, which is a tool for removing the valve core of a tire inflation nozzle. The tire inflation nozzle core removal tool comprises: a main body, which is a long rod, and the long rod has a first end and a second end; the end surface of the first end is provided with a first through hole, and the outer periphery of the proximal end surface of the first end is provided with at least one first through hole connected to the first through hole, and the first through hole has a depth; a first clamping ring, which is plastic, and the outside is provided with a first connecting ring, and the first connecting ring extends toward the inner edge with at least one first elastic column, and the length of the first elastic column extending toward the inner edge is greater than the depth of the first through hole, so that the first elastic column extends out of the first through hole for a section.

The main purpose of the tire inflation nozzle core removal tool of the present invention is that its overall structure is simple, with few components and easy to assemble, which can save assembly process. At the same time, it has excellent stability and reduces production costs, thereby extending the service life. In addition, there is no risk of the valve core falling off during operation. The operation is simple and convenient, and the practicality is improved.

The second through hole 217A is provided at the second annular groove 217. The circumference of the second through hole 217A is smaller than the circumference of the second annular groove 217. The second through hole 218 is a shape that allows the Presta valve 11B to penetrate, but it is not limited to this shape. It can also be set to a shape that allows the Schrader valve 11A to penetrate.

The first clamping ring 22 is plastic, and has a first connecting ring 221 disposed on the outside. The first connecting ring 221 is disposed in the first annular groove 215. The first connecting ring 221 has at least one first elastic column 222 extending inwardly from the first connecting ring 221. The at least one first elastic column 222 is coupled to the at least one first through hole 215A.

The depth of the hole 215A is such that the first elastic column 222 extends out of the first through hole 216. In this embodiment, the number of the at least one first elastic column 222 is two, which are arranged in a relative state. There is at least one first pre-measured space 222A in the first through hole 216 where the first elastic column 222 extends out. A first arc groove 222B is provided at the end where the first elastic column 222 extends out.

The second clamping ring 23 is plastic, and has a second connecting ring 231 on the outside. The second connecting ring 231 is disposed in the second annular groove 217. The second connecting ring 231 extends inwardly with at least one second elastic column 232. The at least one second elastic column 232 is coupled to the at least one second through hole 217A. The length of the second elastic column 232 extending inwardly is greater than the length of the second through hole 217A. The depth of the hole 217A allows the second elastic column 232 to extend a section of the second through hole 218. In this embodiment, the number of the at least one second elastic column 232 is two, which are arranged in a relative state. There is at least one second pre-measured space 232A in the second through hole 218 where the second elastic column 232 extends. A second arc groove 232B is provided at the end of the second elastic column 232 extending out.

When the Schrader gas nozzle 11A is to be disassembled, as shown in FIGS. 9 to 11, the first end 212 of the main body 21 is fitted onto the Schrader gas nozzle 11A, and the slot 212A of the main body 21 is engaged with the two driving surfaces 122A of the Schrader valve core 12A. The Schrader valve core 12A extends into the first through hole 216 of the main body 21, and the first pre-measured space 222A of the first clamping ring 22 allows the first elastic column 222 to form better elasticity, and the first arc groove 222B is used to clamp the Schrader valve core 12A. The ejector pin 123A of the Schrader valve core 12A allows the Schrader valve core 12A to be firmly coupled to the first end 212 of the main body 21. The grip 214 of the main body 21 then drives the first end 212 to rotate, and the first end 212 drives the Schrader valve core 12A to rotate, thereby driving the Schrader valve core 12A to rotate back relative to the Schrader air nozzle 11A until the connection between the Schrader valve core 12A and the Schrader air nozzle 11A is released, completing the removal of the Schrader air nozzle 11A.

When the Presta valve 11B is to be disassembled, as shown in Figures 12 to 14, the second end 213 of the main body 21 is fitted onto the Presta valve 11B, and the Presta valve core 12B extends into the second through hole 218 of the main body 21. The second through hole 218 of the main body 21 engages with the two driving surfaces 122B of the Presta valve core 12B, and the second pre-measured space 232A of the second clamping ring 23 allows the second elastic column 232 to form better elasticity, and the second arc groove 232B clamps The positioning portion 121B of the Presta valve core 12B is held, so that the Presta valve core 12B can be firmly connected to the second end portion 213 of the main body 21. Then, the second end portion 213 is driven to rotate by the holding portion 214 of the main body 21, and the Presta valve core 12B is driven to rotate by the second end portion 213, thereby driving the Presta valve core 12B to rotate back relative to the Presta valve 11B until the connection between the Presta valve core 12B and the Presta valve 11B is released, and the Presta valve 11B is disassembled.

The structure of the above-mentioned specific embodiment can obtain the following benefits: The tire inflation nozzle core removal tool of the present invention has a simple overall structure, few components and is easy to assemble, which can save assembly steps. At the same time, it has excellent stability and reduces production costs, thereby extending the service life. In addition, the valve core 12 does not fall off during operation, and the operation is simple and convenient, and the practicality is improved.
