Description

Air nozzle cover

The present invention relates to a technical field of a gas nozzle cover structure applied to a French air nozzle, and more particularly to a gas nozzle cover which has a function of a sealing nozzle and a disassembly air core group.

Referring to Figures 1 and 2, it is pointed out that the French air nozzle 10 of the general bicycle tire is mainly configured such that a gas core group 12 is screwed into the upper end opening of a gas nozzle head 11, and the gas core group 12 is exposed. A peripheral portion of the outer portion of the nozzle head 11 is provided with an externally threaded portion 13 on which two opposite flat faces 14 are formed. It is further noted in FIG. 1 that the conventional air nozzle cover 15 has a screw hole 16 on the lower side thereof for screwing on the outer thread segment 13 of the air core group 12. Therefore, the conventional air nozzle cover 15 is only It has the function of covering the French air nozzle 10. To disassemble the gas core group 12, a conventional gas core assembly and disassembly tool 17 is additionally prepared, as shown in Fig. 2. The conventional air core assembly and disassembly tool 17 mainly has a through hole 18 for being sleeved on the externally threaded section 13 of the air core group 12, and two opposite side wall walls of the insertion hole 18 form two clamping portions. The flat surface 19 is adapted to be engaged with the two latching planes 14. By the relative clamping action of the two clamping planes 19 and the two latching planes 14, the air core assembly dismounting tool 17 can be easily rotated. The air core group 12 is detached or screwed from the air nozzle head 11. However, due to the disassembly and assembly of the gas core group The size of the tool 17 is very small, and when it is usually carried, it is easy to have problems such as dropping or losing a lot of time.

The main purpose of this creation is to solve the function of the conventional gas nozzle cover which only has the sealing nozzle, so that it is necessary to carry a very small volume of the gas core assembly and disassembly tool, so that the gas core assembly and disassembly often occurs. Tools are easy to drop or lose a lot of time to look for and other problems when you want to use them.

The present invention provides a gas nozzle cover, which is mainly used for screwing on a French air nozzle, the French air nozzle includes a gas nozzle head and a gas core group which is screwed in the opening of the upper end of the gas nozzle head, the gas An outer threaded portion is formed on a peripheral surface of the core group protruding from the outer portion of the air nozzle. Two opposite sides of the outer threaded portion are formed with two latching planes. The air nozzle cover includes a main body and an extending portion. Wherein, one end of the main system has a screw hole for screwing on the external thread segment of the air core group to cover the French air nozzle. The extending portion extends from the other end of the main body, and a through hole is formed in the extending portion for being sleeved on the external thread segment of the air core group, and two opposite side hole walls of the insertion hole are formed with two clips The holding plane can be respectively matched with the two latching planes.

The nozzle cover provided by the present invention can be screwed onto the air core group by a screw hole at one end of the main body to cover the French air nozzle, and in particular, the extension of the other end of the main body The holes on the part are used to remove or lock the air core set. Therefore, the nozzle cover of the present invention can simultaneously have the functions of closing the air nozzle and disassembling the air core group, so that it does not need to carry the air core assembly disassembly tool as the conventional air nozzle cover, and the opposite is relatively easy. There will be no gas core assembly and disassembly tools that are easy to drop or lose. Time rummaging and many other issues.

Referring to Figures 3-6, it is shown that the air nozzle cover 30 of the present invention is mainly for locking on a French air nozzle 20, wherein the French air nozzle 20 includes a gas nozzle head 21 and a core group 22 disposed in the opening of the upper end of the air nozzle head 21, the peripheral portion of the air core group 22 protruding from the air nozzle head 21 is provided with an external thread section 23, the external thread section 23 Two latching faces 24 are formed on opposite sides of the body.

The air nozzle cover 30 includes a main body 31 and an extension portion 32. One end of the main body 31 has a screw hole 33 for screwing on the external thread segment 23 of the air core group 22 of the French air nozzle 20 to cover the French air nozzle 20. The extending portion 32 extends integrally from the other end of the main body 31. The extending portion 32 is provided with a through hole 34 for being sleeved on the externally threaded portion 23 of the air core group 22, and the two opposite sides of the through hole 34 The side wall system is formed with two clamping planes 35 for being opposite to the two latching planes 24, by the two clamping The flat surface 35 and the two latching planes 24 function as opposite latches, and the air core pack 22 can be easily removed or screwed from the air nozzle head 21 by simply rotating the air nozzle cover 30. In addition, the outer peripheral surface of the main body 31 is further provided with a plurality of anti-slip lines 36 for increasing the friction force, so that the air nozzle cover 30 can be unscrewed or screwed from the French air nozzle 20 by a convenient force.

The air nozzle cover provided by the present invention can be screwed to the air core group 22 by the screw hole 33 at one end of the main body 31 to cover the French air nozzle 20. Moreover, the air core group 22 can be detached or locked by the insertion holes 34 in the extension portion 32 at the other end of the main body 31. Therefore, the nozzle cover 30 of the present invention can simultaneously have the function of covering the French air nozzle 20 and disassembling the air core group 22, so that it is not necessary to carry the air core assembly disassembly tool as in the conventional air nozzle cover. In contrast, there is no problem that the air core assembly and disassembly tool is easy to drop or lose, or it takes a lot of time to look for it when using it.
