DETAILED DESCRIPTION

[0028] Embodiment 1

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1-Figure 4 As shown, the utility model provides a quick connection structure for repairing water supply and drainage pipes, comprising:

[0032] Connect bracket 1;

[0033] A connecting pipe 3 is arranged on the connecting bracket 1;

[0034] A housing 4 is arranged on the connecting pipe 3;

[0035] A rotating member 5 is rotatably disposed on the housing 4 and is used for rotation limit locking of the housing 4;

[0036] Butt pipe 11;

[0037] A limiting rod 13 is arranged on the butt-jointed pipe 11;

[0038] The limiting member 12 is arranged on the butt-jointed pipe 11 .

[0039] The connecting bracket 1 is provided with a plurality of mounting holes 2 , and internal threads are provided inside the plurality of mounting holes 2 .

[0040] The housing 4 is provided with a circular groove, a spring is provided inside the circular groove, an elastic limiting member 16 is provided on the other end of the spring, and the side surface of the elastic limiting member 16 is in contact with the limiting hook 8 .

[0041] The rotating member 5 is rotatably provided with a rotating shaft 6 , the rotating member 5 is provided with a limit hook 8 , the housing 4 is provided with a limit groove 10 , the housing 4 is provided with a docking groove 9 , and the rotating member 5 is provided with a handle 7 .

[0042] The housing 4 is provided with a sealing ring 15 , which is in contact and extruded with the butt joint pipe 11 . The butt joint pipe 11 is provided with a limiting rod 13 , which is slidably connected with the butt joint groove 9 , and the limiting member 12 is in contact with the limiting groove 10 .

[0043] The butt joint pipe 11 is provided with a mounting bracket 14 , and the structure of the mounting bracket 14 is the same as that of the connecting bracket 1 .

[0044] The butt joint pipe 11 is provided with a waterproof layer, and the waterproof layer is in contact with the sealing ring 15 .

[0045] In this embodiment, the combination of the outer shell 4 and the docking tube 11 can achieve the effect of rapid docking and fixing of the device. Compared with the traditional device, the device can effectively avoid the long-term rotation of the bolt fixing method through the rotation limit method. At the same time, since the device does not use the locking bolt, there is no problem of bolt loosening, thereby improving the docking stability.

[0046] When the device is in working state, the combination of the connecting bracket 1 and the mounting hole 2 can facilitate the installation and fixation of the device on one end of the water pipe, and the mounting bracket 14 is installed on the water pipe to be docked at the other end. At this time, the docking effect is achieved by moving the docking tube 11 toward the direction of the outer shell 4.

[0047] When the docking tube 11 enters the shell 4, the limiting rod 13 enters the docking groove 9 to slide, and the limiting member 12 approaches the inner wall of the limiting groove 10. At this time, the handle 7 rotates toward the connecting bracket 1, so that the limiting hook 8 rotates clockwise.

[0048] When the butt joint tube 11 slides to the point where the limit member 12 and the limit groove 10 are in contact with each other, the butt joint tube 11 is in contact and squeezed with the sealing ring 15, and the butt joint tube 11 cannot continue to extend and slide. The structure of the limit member 12 can prevent the butt joint tube 11 from excessively squeezing the sealing ring 15, thereby ensuring the sealing stability of the sealing ring 15. At this time, the limit rod 13 is located deep in the butt joint groove 9.

[0049] When the connecting tube 11 cannot slide, the elastic limit member 16 is pressed inward in advance, and the handle 7 is rotated at the same time, so that the limit hook 8 rotates counterclockwise, and the limit rod 13 is limited by the groove of the limit hook 8, thereby achieving the locking effect of the connecting tube 11 and the shell 4. When the limit hook 8 passes through the elastic limit member 16, the elastic limit member 16 pops outward, thereby preventing the limit hook 8 from accidentally rotating clockwise, thereby achieving the locking effect of the limit hook 8, which can effectively prevent the device from being accidentally unlocked.

[0050] Embodiment 2

[0051] like Figure 1-Figure 4 As shown, the quick connection structure for repairing water supply and drainage pipes proposed by the utility model is compared with the first embodiment. In this embodiment, the limiting hook 8 is U-shaped, and the internal width of the limiting hook 8 is greater than the diameter of the limiting rod 13.

[0052] The U-shaped limiting hook 8 structure can achieve a limiting locking effect on the limiting rod 13 by rotation, and the structure of the limiting rod 13 can achieve a locking effect on the docking of the butt pipe 11 .

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
