Problems solved by technology

Due to the large resistance in the process of moving the handle, if you do not use force or do not use enough force to fix the joint body first, and directly lift the handle with one hand, the mouth body may be damaged or even broken.
In the repair shop, this kind of damage to the valve caused by the handle is not uncommon
Obviously, such an operation is cumbersome and laborious, and the valve is not safe enough, and it is completely impossible to install or remove such a joint with one hand

Abstract

A handle screwing type American valve joint comprises a joint pipe and an upper joint cover. The bottom of the joint pipe is provided with a joint pipe bottom hole matched with an inflating valve body on a tire. An elastic ring, a movable body and an adjusting bolt are sequentially arranged in an inner cavity of the joint pipe from bottom to top. A bottom pressure plate of the adjusting bolt evenly applies action force to the end face of the elastic ring through the movable body. The diameter of an inner hole in the elastic ring is equal to or slightly larger than the outer diameter of the inflating valve body. The outer wall of the joint pipe and the movable body are respectively provided with a notch for containing an escape pipe of an inflating device. The lower end face of the movable body is provided with a central concave hole communicated with the notch in the movable body. A central pressure tongue used for ejecting a valve core rod in the inflating valve body is arranged in the central concave hole. The joint is easy to operate and hold, and operation can be completed even with one hand. In addition, in the process of detaching the joint, tire air will not leak obviously even if the joint is detached slowly.

Description

technical field [0001] The invention relates to a joint of an inflating device, in particular to a rotary handle type beautiful mouth joint. Background technique [0002] In the tires of automobiles, bicycles, mountain bikes, etc., the application of American valves accounts for the vast majority. There are two common inflation joints for American valves: one is the helmet type. The disadvantage of this method is that when the tire is inflated and rotated in the opposite direction to pick up the conversion cap, there will be more air leakage, which is extremely unsatisfactory. The second is the handle-type joint, which is quick to remove and has less air leakage. However, when installing the joint, it is necessary to fix the joint body with one hand to keep the relative direction of the pipe body and the valve in the same direction. When taking the conversion head, do the opposite operation with both hands. Due to the large resistance in the process of moving the handle, ...
