Abstract

The present invention relates to an air valve adjustment structure of a core extension rod, particularly to a bicycle with the adjustable air valve being a French valve core. The structure comprises: an extension rod body disposed thereof with an extension rod flattened part; a sleeve part disposed at a bottom end of the extension rod ; and a reinforcing rod provided therein with a hollow part, female threads disposed on an inside diameter of a bottom part, and a plug provided with knurling on an outside diameter thereof and a recessed slot disposed on the bottom part. The extension rod flattened part, when sleeved into the hollow part of the reinforcing rod, projects outside the reinforcing rod. The portion of the extension rod flattened part that projects outside the reinforcing rod can be cut off to be consistent in length with the reinforcing rod, so that the plug can be plugged into the hollow part of the reinforcing rod and the recessed slot disposed on the bottom of the plug, making the plug engaged with the extension rod flattened part. When a user places the extension rod body into the hollow part of the reinforcing rod with the sleeve part of the extension rod sleeved to a French core of the tire, the female thread disposed on the inside diameter of the bottom part of the reinforcing rod can be threaded with a male thread provided on the French core, so that the user may use the knurling provided on the outside diameter of the plug to rotate the plug for driving the extension rod flattened part, thereby rotating the sleeve part of the extension rod to drive the French core of the tire, so as to adjust a tire pressure of the tire.

Description

Air valve adjustment structure of air core extension rod

The invention relates to a gas valve adjusting structure of a gas core extension rod, in particular to a gas valve adjusting structure capable of adjusting a gas cylinder extension rod of a bicycle tire nozzle as a French air core.

Press, as the riding bicycle has changed from a traditional one to a sports competition, the average person also regards riding a bicycle as a fitness exercise mode. At present, on the bicycle, the common tire valve can be roughly divided into American and French. In particular, the bicycles used in bicycle racing mostly use French air cores, and in order to increase the strength and weight of the rims, carbon fiber is combined with the wheel frame to become a wide carbon fiber spoke. First, because the tire valve is fixed length, the valve can not grow beyond the wide carbon fiber spoke, so that the user can not adjust the tire pressure or timely air, so the inventor research and improvement The invention was finally born.

The air valve adjusting structure of the air core extension rod comprises three components, such as an extension rod body, a plug body and a reinforcing rod, and the three components respectively have independent structures, and the three components can be combined to cost the invention when used. The user is used in a bicycle tire with a French air core; the technical features of the three-element structure are detailed as follows; an extension rod body is provided with a flat portion of the extension rod and the bottom end of the extension rod is provided with a sleeve portion and a reinforcing rod therein a hollow portion is provided and a female thread is arranged on the inner diameter of the bottom portion; a plug body is provided with an embossing at the outer diameter thereof, and a groove is provided at the bottom portion; the extension rod body is placed in the hollow portion of the reinforcing rod and is extended The bottom end of the rod is provided with a sleeve to cover the French air core on the tire. At this time, the female thread on the inner diameter of the bottom of the reinforcing rod can be screwed with the male thread on the French air core, and the user can The embossing provided at the outer diameter of the plug body is used to rotate the plug body to drive the flat portion of the extension rod to rotate the sleeve portion of the extension rod and drive the French gas core of the tire, thereby adjusting the tire pressure of the tire. For details and technical contents of the present invention, please refer to the following illustrations:

Please refer to the drawings: a gas valve adjusting structure of a gas core extension rod, which comprises three elements, such as an extension rod body 10, a plug body 30, and a reinforcing rod 20, and the three elements respectively have independent structures, and the three elements respectively When used, the invention can be combined to facilitate the user to use the bicycle tire 50 having the French air core 40; an extension rod body 10 is provided with a flat portion 12 and the extension rod body 10 is provided with a sleeve portion 14 at the bottom end thereof, A reinforcing rod 20 is provided with a hollow portion 24 therein, and a female thread 22 is disposed on the inner diameter of the bottom portion of the reinforcing rod 20, an embossing 32 is provided at the outer diameter of the plug body 30, and a groove 34 is provided on the bottom portion as the extension rod The flat portion 12 is inserted into the hollow portion 24 of the reinforcing rod 20 and protrudes from the reinforcing rod 20, and the portion of the elongated portion 12 of the elongated rod body 10 that is too long can be sheared to match the length of the reinforcing rod 20, and The plug body 30 is inserted into the hollow portion 24 of the reinforcing rod 20, and the bottom of the plug body 30 is provided with a groove 34 so as to be engaged with the flat portion 12 of the extension rod body 10, and The user places the extension rod body 10 into the hollow portion 24 of the reinforcing rod 20, and sets the sleeve portion 14 of the extension rod body 10 The female air core 40 of the tire 50 is screwed to the female thread 22 on the inner diameter of the bottom of the reinforcing rod 20 at this time, and the user can use the plug body 30. The embossing 32 is provided at the diameter, so that the flat portion 12 of the extension rod body 10 can be rotated to rotate the sleeve portion 14 of the extension rod body 10 and drive the French air core 40 of the tire 50, thereby adjusting the tire 50.
