DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to be able to more clearly understand the above objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0018] Example 1, as Figure 1 、 Figure 2 shown, a split quick-connect fitting of the present application includes a female fitting end 1 and a male fitting end 2. The female fitting end 1 is a straight section, and the male fitting end 2 is an L-shaped end. A connecting ring 3 is built into the female fitting end 1, and the connecting ring 3 divides the inner cavity of the female fitting end 1 into two parts. The left end of the connecting ring 3 is a first cavity 4, and the right end of the connecting ring 3 is a second cavity 5;

[0019] A first sealing rubber ring 6 is fixedly connected to the left-side outlet of the male fitting end 2; the first sealing rubber ring 6 is annular, and a first collision ring 7 is fixedly installed on the left side surface of the first sealing rubber ring 6; the first collision ring 7 is fixedly connected to a second collision ring 9 through an elastic member 8; the elastic member 8 is a cylindrical shape with left and right through-holes, and its side surface is circularly arrayed with up and down through-holes; after collision, the side surface of the elastic member 8 has a tendency to expand outwards. The middle part of it is a fan-shaped ring formed by being separated by the concave holes. Utilizing the characteristics of the fan-shaped ring and the elasticity of the elastic member 8 itself, the middle part of the elastic member 8 has a tendency to recover to an arc shape, so that there are an expanded state and a contracted state in the middle part of the elastic member 8; during use, by inserting the male fitting end 2 into the female fitting end 1 from the right side of the female fitting end 1, the left side surface of the second collision ring 9 impacts the right side surface. Subsequently, due to the collision of the second collision ring 9, the first collision ring 7 and the second collision ring 9 are squeezed towards the center of the two, causing the side surface of the elastic member 8 to expand and increase its central diameter, making the maximum diameter of the elastic member 8 larger than the inner diameter at the second cavity 5 of the female fitting end 1. The elastic member 8 firmly abuts against the inner wall of the second cavity 5 of the female fitting end 1, realizing the stable connection between the female fitting end 1 and the male fitting end 2;

[0020] A second sealing rubber ring 10 is fixedly connected to the inner wall of the second cavity 5. The second sealing rubber ring 10 is arranged to be in contact with the outer side surfaces of the first collision ring 7, the elastic member 8, and the second collision ring 9, and the right side surface of the second sealing rubber ring 10 is arranged to be in contact with the left side surface of the first sealing rubber ring 6; specifically, when the male fitting end 2 is connected to the female fitting end 1, the second sealing rubber ring 10 is wound around the outer side surfaces of the first collision ring 7, the elastic member 8, and the second collision ring 9, and cooperates with the outer contour of the expanded elastic member 8. While strengthening the stability between the female fitting end 1 and the male fitting end 2, the second sealing rubber ring 10 and the first sealing rubber ring 6 cooperate to maintain the airtightness inside the female fitting end 1 and the male fitting end 2;

[0021] Holes are respectively provided on the top surface and the bottom surface of the second cavity 5 of the female end 1 of the connector. A button 11 and a spring 12 are arranged in the holes. The cross-section of the button 11 is T-shaped. The button 11 includes a vertical section and a horizontal section. Two ends of the spring 12 are respectively fixedly connected with the inner side surface of the horizontal section of the button 11 and the outer side surface of the second sealing rubber ring 10. The vertical section of the button 11 is aligned with the middle part of the elastic member 8. The horizontal section of the button 11 is in contact with the inner side surface of the hole. During use, by pressing the button 11 to squeeze the middle part of the elastic member 8, the elastic member 8 is restored to a contracted state. At this time, the diameter of the elastic member 8 is smaller than the inner diameter of the second cavity 5 of the female end 1 of the connector, so as to realize the separation of the male end 2 of the connector from the female end 1 of the connector.
