US and French gas nozzle universal joint

This creation is related to the gas nozzle joint, and more specifically refers to a US-style gas nozzle universal joint.

According to the bicycle tires, there are many types of air nozzles, which are mainly divided into American air nozzles and French air nozzles.
For the different types of nozzles, the conventional inflation joints cannot be used universally, so they need to be replaced, and the replacement is inconvenient. Therefore, many manufacturers have developed inflatable joints that can be used with American air nozzles and French air nozzles. The main purpose is to design a movable ejector inside, and the movable pin can clamp the ejector pin to facilitate the thimble. The French air nozzle can be inflated when being pushed in, and the American air nozzle can be inflated when the ejector pin is pushed out, and the thimble is fixed by the clamp.
However, the types of clips designed by the various manufacturers are different. For example, as disclosed in Chinese Patent No. M251030, the main purpose is to design a movable pivoting clamp (or automatic claw) to clamp the thimble, which not only clamps the force. Slightly insufficient, and more components are required, resulting in higher manufacturing costs and difficulties in assembly.

In view of this, in order to improve the prior art, the conventionally used inflation joints for the American air nozzle and the French air nozzle have problems such as insufficient clamping force, required components, high manufacturing cost, and difficulty in assembly; The present invention provides a universal mouthpiece universal joint, which mainly comprises: a casing having a chamber and a perforation connecting the chamber to the outside; a handle pivotally connected to one end of the casing, Reciprocating pivoting between the pressing position and a loose position; a pressure injection member is disposed in the housing of the outer casing, and the pressure injection member has a receiving hole extending inwardly at one end thereof, and the two sides of the pressure injection member respectively have a connection The two clamping block units respectively have a clamping block, and the clamping block is placed in the working hole of the pressing member, and can be externally applied to an inner clamping position to an external releasing position. Reciprocating displacement, the clamp has a clip slope;
An compression ring, which is elastic, is placed in the housing of the outer casing; a linkage member is disposed between the pressure injection member and the compression ring, and has a linkage inclined surface; a thimble unit is placed on the pressure injection member In the hole, the external force acts on the reciprocating displacement between an American position and a French position; when an American air nozzle extends into the perforation of the outer casing to inflate, the handle pivoted from the loose position to the pressing position will be displaced. The pressure injection member is connected to the linkage member by the pressure injection member to press the compression ring to be deformed and tightened on the American air nozzle, and the clamp slope of the clamp block is in contact with the interlocking inclined surface of the linkage member, so that the clamp block is The external release position moves to the inner clamp position and is clamped on the ejector unit; thereby achieving the effects of stable clamping force, less components, low manufacturing cost, and easy assembly.
