Dual-air tap inflating joint capable of improving air leakage

Abstract

The invention provides a dual-air tap inflating joint capable of improving air leakage, comprising a dual opening cylinder, a centering piece and a toggle piece, wherein the centering piece is accommodated in an accommodation hole of the dual opening cylinder and can move relative to the accommodation hole of the dual opening cylinder; a first O-shaped ring is sleeved at the first end of the centering piece; a second O-shaped ring is sleeved at the second end of the centering piece; a penetrating hole is arranged between the first end and the second end of the centering piece; the toggle piece is provided with an eccentric block which can push the centering piece to slide left and right; O-shaped rings are sleeved at two ends of the eccentric block; when the toggle piece is not spanned, afirst inflating space and a second inflating space of the centering piece are not communicated; and the second inflating space of the centering piece is communicated with a channel of the dual opening cylinder. With the technical scheme provided by the invention, the air leakage phenomenon that a pumping head is connected with the air tap can be improved; the air leakage situation that the togglepiece is spanned after the charging is finished to release the air tap of a bicycle type can be avoided; and the dual air tap inflating joint is convenient to process, can effectively save the cost and has the convenience and the practicability.

Description

technical field [0001] The invention mainly relates to an inflatable joint, in particular to an inflatable joint with double air nozzles which can improve air leakage. Background technique [0002] In the Patent Application No. 200420087899 of the People's Republic of China, which is applicable to the pump patent of various valves, the toggle handle has a long handle, and an eccentric block is formed at one end, and a threaded part is provided at one end of the eccentric block. A fixed body can be used to pass through the through round hole of the double-open cylinder and the through square hole of the transmission cylinder, so that the threaded part of the eccentric block of the toggle handle is screwed into the screw hole of the fixed hole, so after dialing The toggling of the moving handle can make the air pressure pass through the inflator body and be filled to the tuyere mouth of the set specification. [0003] The double-opening pump air nozzle of the prior art utiliz...

Problems solved by technology

[0004] Moreover, after the bicycle tire air nozzle is inflated, the toggle handle is pulled to connect the two ends of the double-opening cylinder, and then there will be an air leakage when the inflation nozzle is removed after the inflation is completed. In view of the above-mentioned prior art Shortcomings, the present invention proposes a dual-air nozzle inflatable joint that can improve air leakage, which can overcome all the above-mentioned shortcomings
