Fast-inserting connecting device and assembling method thereof

Abstract

The invention provides a fast-inserting connecting device and an assembling method thereof. The fast-inserting connecting device realizes a longitudinal and axial fast connecting function through a fast-inserting body, an elastic member, straight pins, a button and a connector. The connector is provided with a limiting groove, an axial groove is formed in the fast-inserting body, a pair of elastic arms passing through the elastic member are placed in a chute and are elastically attached to the straight pins placed in the chute, so that the straight pins are clamped into the limiting groove to limit and fix the connector, and therefore, the connector is quickly fixed in the fast-inserting body; when the button is pushed, an inclined block pushes the straight pins, so that the second distance between the straight pins is greater than the dimension of the inserting end, and the connector is easily pulled out. The device is elastic and comfortable in operation, and after repeated use, the device still maintains good elasticity, and further has the characteristics of simple structure, safety and reliability, low cost and the like.

Description

technical field [0001] The invention relates to a plug connector, in particular to a quick-plug connection device and an assembly method thereof. Background technique [0002] A releasable plug-in connector arrangement with a plug-in coupling part and a plug-in part for connecting, for example, lines or hose lines on liquid or compressed air lines. By inserting the plug connector into the receptacle of the coupling part, a fluid-tight connection can be produced between the plug connector and the coupling part, while the locking element is used to secure the plug connector in the receptacle. [0003] Invention application CN101356397B discloses a connector of a plug connector device. The basic principle can be summarized as follows: the elastic element and the locking element are designed as one part, wherein the U-shaped part in the middle is an elastic element for elastic function, and The bent parts at both ends are locking parts, which are used for locking. This design ...

Problems solved by technology

[0004] However, if the fluid pressure is high, the diameter of the locking part must be larger due to the need for strength. In view of the integrated design of the elastic element and the locking part, the diameter of the U-shaped part is also larger, and the larger diameter is in the U-shaped part. In the case of limited length, the elasticity is very poor, that is to say, the elastic element loses its elasticity, which leads to the need to use a lot of force to push it in actual operation

Such operation reduces the comfort. In addition, the poor elasticity of the elastic element will cause permanent deformation of the elastic element after multiple operations, that is to say, after permanent deformation, the distance between the two locking parts in the natural state will be close to or equal to or even greater than the loose The distance from the off state makes it lose the locking function in the natural state
