Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1-2, a flat push type quick connector, including: shell 1, big tiger mouth 2, small tiger mouth assembly 3 and big tiger mouth anti-detachment hook 4, wherein: shell 1 is welded left and right by steel plates on both sides symmetrically Composition; the big tiger mouth 2 is set under the front side of the shell 1; the small tiger mouth assembly 3 is set between the shells 1, and is slidingly connected with the inner side of the shell 1; the big tiger mouth anti-detachment hook 4 is set between the shells 1, through The rotating shaft 5 is connected with the housing 1 , and the large tiger's mouth anti-detachment hook 4 is rotated around the rotating shaft 5 during the sliding process of the small tiger's mouth assembly 3 .

The small tiger's mouth component 3 of the utility model is stressed by means of the shell to reduce the damage of the small tiger's mouth, and the opening and closing structure of the large tiger's mouth anti-detachment hook 4 is controlled by the sliding of the small tiger's mouth component 3. The structure is ingenious, simple and easy to operate.

As a further solution of this embodiment, the inner side of the housing 1 is provided with a sliding track 6 , the small tiger mouth assembly 3 slides under the action of the mechanical cylinder 7 , and the mechanical cylinder 7 is arranged between the housings 1 .
