DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figures 1 to 7 A stainless steel pipe that is easy to connect includes a pipe body 1 and a protruding tube 3. The pipe body 1 and the protruding tube 3 can be an integrally formed structure, and the outer diameter of the protruding tube 3 is smaller than the outer diameter of the pipe body 1.

[0032] An adjustment assembly 2 is provided on the tube body 1, and an ejection block 4 is slidably mounted on the extension tube 3. A limiting groove 16 adapted to the ejection block 4 is provided at a corresponding position of the tube body 1;

[0033] When the extension tube 3 moves toward the inside of the tube body 1 , after moving to the corresponding position, the ejection block 4 will be located inside the limiting groove 16 , thereby realizing the rapid splicing of adjacent tube bodies 1 .

[0034] The adjustment assembly 2 includes a fixed cylinder 7 and a connecting rod 14, and a slide groove 8 is provided on the fixed cylinder 7;

[0035] A pressing plate 15 is fixedly installed at the bottom of the connecting rod 14. By moving the connecting rod 14 up and down, the height of the pressing plate 15 can be changed. By moving the pressing plate 15, the ejection block 4 can be disengaged from the limiting groove 16, thereby facilitating disassembly activities.

[0036] The upper end of the connecting rod 14 is fixedly mounted with a mounting plate 9, a rotating ring 10 is rotatably mounted on the mounting plate 9, a connecting block 11 is fixedly mounted on the rotating ring 10, and an operating rod 12 is fixedly mounted on the connecting block 11;

[0037] The operating rod 12 facilitates movement and rotation operations.

[0038] A spring 13 is provided on the mounting plate 9 .

[0039] The bottom of the mounting plate 9 is fixedly connected to the spring 13, and the other end of the spring 13 is fixedly mounted on the surface of the tube body 1. The spring 13 is used to provide a vertical upward force for the mounting plate 9, so as to keep the overall device stable when not in use.

[0040] The pressing plate 15 is located inside the limiting groove 16 and can slide inside the limiting groove 16 .

[0041] The slide slot 8 is composed of a rotating slot 17 and a lifting slot 18 . The lifting slot 18 allows the connecting block 11 to move up and down, and the rotating slot 17 allows the connecting block 11 to rotate.

[0042] When the connecting block 11 moves on the lifting slot 18, the connecting rod 14 and the pressing plate 15 can be moved in the vertical direction, so that the ejecting block 4 can be disengaged.

[0043] When the connecting block 11 is at the end of the lifting groove 18, the connecting block 11 is rotated. At this time, the connecting block 11 will move on the rotating groove 17. When the connecting block 11 moves to the end of the rotating groove 17, the force is cancelled. Under the action of the spring 13, the connecting block 11 will be pushed to the narrower part of the L-shaped structure of the rotating groove 17, so that the connecting block 11 cannot move, thereby ensuring the stability of the connecting block 11 when it is not subjected to force.

[0044] The number of the rotation grooves 17 is two, and the rotation groove 17 is L-shaped in a front view.

[0045] An accommodating cavity 6 for accommodating the extending tube 3 is provided on one end of the tube body 1 away from the adjusting assembly 2, and the accommodating cavity 6 can also perform positioning activities synchronously.

[0046] A sealing ring 5 is embedded and installed on the end of the extension tube 3 facing away from the tube body 1. The sealing ring 5 can be against the inner wall of the tube body 1. When the extension tube 3 is inside the tube body 1, the sealing ring 5 fits tightly with the inner wall of the tube body 1, thereby ensuring that no fluid leakage occurs.

[0047] The working process of the utility model is to make the extension tube 3 move toward the inside of the tube body 1. When it moves to the corresponding position, the ejection block 4 will be inside the limiting groove 16, thereby realizing the rapid splicing activity of the adjacent tube bodies 1. At this time, the sealing ring 5 fits tightly with the inner wall of the tube body 1, thereby ensuring that no fluid leakage occurs.

[0048] At this time, the connecting block 11 is in the concave groove at the end of the upper rotating groove 17. At this time, the spring 13 makes the connecting block 11 stably in this position, the connecting rod 14 cannot move, and the pressure plate 15 cannot move, thereby ensuring that the ejection block 4 is stably in the limiting groove 16, so that the adjacent tube bodies 1 remain stably connected.

[0049] When disassembly is required, the connecting block 11 is moved out of the upper rotating groove 17, and then the connecting block 11 makes the lifting groove 18 move upward. When the connecting block 11 is at the end of the lifting groove 18, the connecting block 11 is rotated. At this time, the connecting block 11 will move on the rotating groove 17. When the connecting block 11 moves to the end of the rotating groove 17, under the action of the spring 13, the connecting block 11 will be pushed to the narrower part of the L-shaped structure of the rotating groove 17. When the connecting rod 14 moves up and down, the height of the pressing plate 15 can be changed. Through the movement of the pressing plate 15, the ejection block 4 can be disengaged from the limiting groove 16, thereby facilitating disassembly.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
