When connecting, it is necessary to use bolts step by step and repeatedly to firmly fix the two flanges, which is troublesome, time-consuming and labor-intensive. Secondly, the existing pipe joint device cannot be directly inserted and connected during use, which is more troublesome and requires the cooperation of other parts to complete the connection operation.

[0010] As a preferred technical solution of the utility model: the diameter of the butt-joint pipe is smaller than the diameter of the outer pipe, and the diameters of the first and second circular rings are matched.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The plug-in pipe joint, through the coordinated use of the clamping block 2 and the clamping slot, utilizes the handle to drive the clamping plate to squeeze and contract the spring 2. At this time, the clamping block 2 is inserted into the inner wall of the clamping slot, and then the handle is released, and the elastic potential energy of the spring 2 is utilized to drive the clamping plate to return to its original position, so that the friction plate fits with the clamping slot and clamps the clamping slot, thereby making the fit between the circular ring 1 and the circular ring 2 more firm and stable, without the need to use bolts for fixing, reducing the steps of repeatedly turning the bolts for loosening and tightening, and reducing the work intensity of the staff.

[0013] 2. The plug-in pipe joint is used by cooperating with the clamping block 1 and the square groove. The butt-joint pipe is inserted into the circular groove opened at the outer end of the outer pipe. At this time, the inner side of the circular groove squeezes the clamping block 1, so that the clamping block 1 squeezes the spring 1, causing the clamping block 1 to shrink in the square groove inside the butt-joint pipe. Then, when the butt-joint pipe is inserted into the bottom of the inner wall of the circular groove, the butt-joint pipe is rotated at this time, so that the clamping block 1 and the square groove inside the outer pipe are docked, causing the clamping block 1 to be clamped in the square groove inside the outer pipe for preliminary plugging. Then, by using the principle of opposites attracting each other, the N pole and the S pole can be attracted and fitted to each other through the action of magnetic force, causing the circular ring 1 and the circular ring 2 to fit together.

[0022] In the above structure, the friction plate 14 is arranged in combination with the spring 2 11 , so that the connection between the circular ring 1 3 and the circular ring 2 4 can be made tighter and more secure.

[0023] In a preferred embodiment: the clamping block 7 is slidably connected to the inner wall of the square groove 5 , and the clamping block 7 is slidably connected to the inner wall of the circular groove 15 .

[0024] In the above structure, through the sliding connection between the clamping block 7 and the square groove 5, when the butt joint pipe 2 is rotated, the clamping block 7 is separated from the square groove 5 on the inner side of the outer tube 1, and then the outer tube 1 and the butt joint pipe 2 can be smoothly separated by utilizing the sliding connection between the clamping block 7 and the inner wall of the circular groove 15.

[0025] In a preferred embodiment: round holes are formed at both ends of the outer side of the second clamping block 10, and the handle 13 is slidably connected to the inner wall of the round hole.

[0026] In the above structure, through the setting of the circular hole, the handle 13 can be used to pull the clamping plate 12 smoothly, so that the clamping plate 12 squeezes the spring 2 11 to deform and shrink. At this time, the friction plate 14 and the inner wall of the slot 8 are separated, and the clamping block 2 10 can be taken out of the inner wall of the slot 8, so that the outer tube 1 and the docking tube 2 can be separated smoothly.

[0029] In a preferred embodiment, the clamping plate 12 is slidably connected to the inner side of the second clamping block 10 .

[0030] In the above structure, through the sliding connection between the clamping plate 12 and the inner side of the second clamping block 10, the second clamping block 10 can be smoothly driven by the handle 13 to slide outward on the inner wall of the clamping plate 12, thereby squeezing the second spring 11 to deform and contract.

[0032] In the above structure, by setting the diameter of the butt joint pipe 2 smaller than the diameter of the outer pipe 1, the butt joint pipe 2 can be smoothly inserted into the inner wall of the circular groove 15 opened at the outer end of the outer pipe 1, so as to be smoothly plugged.

[0033] Working principle: When the device is needed, first, the butt joint tube 2 can be inserted into the circular groove 15 opened at the outer end of the outer tube 1. At this time, the inner side of the circular groove 15 squeezes the card block 7, so that the card block 7 squeezes the spring 6, causing the card block 7 to shrink in the square groove 5 inside the butt joint tube 2. Then, when the butt joint tube 2 is inserted into the bottom of the inner wall of the circular groove 15, the butt joint tube 2 is rotated at this time, so that the card block 7 and the square groove 5 inside the outer tube 1 are docked, causing the card block 7 to be clamped in the square groove 5 inside the outer tube 1 for preliminary plugging. Then, by using the principle of opposites attracting each other, the N pole and the S pole can be mutually attracted by the action of magnetic force. Attraction and fitting cause the circular ring 1 3 and the circular ring 2 4 to fit together, and then the handle 13 is pulled outward, and the handle 13 is used to drive the clamping plate 12 to squeeze and contract the spring 2 11. At this time, the clamping block 2 10 is inserted into the inner wall of the clamping groove 8, and then the handle 13 is released, and the elastic potential energy of the spring 2 11 is used to drive the clamping plate 12 to return to its original position, so that the friction plate 14 fits with the clamping groove 8 and clamps the clamping groove 8, thereby making the fitting between the circular ring 1 3 and the circular ring 2 4 more firm and stable, without the need to use bolts for fixing, reducing the steps of repeatedly turning the bolts for loosening and tightening, and reducing the work intensity of the staff.

[0034] 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.
