[0034] The quick connection mechanism 3 includes a female connector 301, a sub-connector 302, an insert ring 303, a slot 304, a fixing ring 1 305, a fixing ring 2 306, a T-shaped block 307, a perforation 308, a slide groove 309, a mounting ring 310 and a locking bolt 311.

The insert ring 303 is fixedly connected to the side wall of the female connector 301, the slot 304 is provided on the side wall of the sub-connector 302, the insert ring 303 is adapted to the slot 304, and the fixing ring 1 305 is fixedly connected to the female connector 30 1, a second fixing ring 306 is fixedly connected to the side wall of the sub-joint 302, four T-shaped blocks 307 are fixedly connected to the side wall of the first fixing ring 305, four through holes 308 are provided on the side wall of the second fixing ring 306, the T-shaped blocks 307 are movably connected to the through holes 308, four slide grooves 309 are provided on the side wall of the second fixing ring 306 and are through-matched with the through holes 308, two mounting rings 310 are respectively fixedly connected to the side walls of the female joint 301 and the sub-joint 302, and four sets of locking bolts 311 are respectively arranged on the mounting ring 310 and the middle of the flange 2.

[0035] Specifically, Figure 7 As shown, six positioning strips 5 are arranged on the side wall of the sub-connector 302 , and six positioning grooves 6 are opened on the side wall of the pipe 1 to be connected, and the positioning strips 5 are movably connected to the positioning grooves 6 .

[0036] Specifically, Figure 7 As shown, a plug 7 is fixedly connected to the inner wall of the female connector 301 and the sub-connector 302. The plug 7 is movably connected to the pipe 1 to be connected, and one end of the plug 7 is inclined.

[0039] Specifically, Figure 7 As shown, two protective covers 13 are bolted to the side wall of the second fixing ring 306 , and the protective covers 13 are located outside the two sliding grooves 309 .

[0040] First, the female connector 301 and the sub-connector 302 are respectively sleeved on the ports of the two sections of the pipe 1 to be connected. At this time, the positioning strip 5 on the side wall of the sub-connector 302 is movably connected with the positioning groove 6 on the side wall of the pipe 1 to be connected to ensure the correct alignment of the sub-connector 302 and the pipe 1 to be connected. The plug ring 303 on the side wall of the female connector 301 and the slot 304 on the side wall of the sub-connector 302 are adapted to each other to achieve the preliminary connection between the two sections of the pipe 1 to be connected. The rubber ring 12 bonded to the inner wall of the slot 304 can enhance the sealing and friction between the plug ring 303 and the slot 304 to ensure a tight connection. The T-shaped block 307 on the fixing ring 1 305 is movably connected with the through hole 308 and the slide groove 309 on the fixing ring 2 306. The female connector 301 is rotated to make the T-shaped block 307 slide, so that the female connector 301 and the sub-connector 302 are connected. The female connector 301 and the sub-connector 302 are tightly fitted together, and the inner walls of the female connector 301 and the sub-connector 302 are fixedly connected with a cannula 7. One end of the cannula 7 is tilted to facilitate the insertion of the cannula 7. The sealing gasket 8 embedded on the side wall of the cannula 7 can enhance the sealing between the cannula 7 and the sub-connector 302 to prevent leakage. The mounting ring 310 is fixed with the locking bolt 311. The two mounting rings 310 are respectively fixedly connected to the side walls of the female connector 301 and the sub-connector 302. The locking bolt 311 is rotated to pass through the mounting ring 310 and the middle part of the flange 2, so that the female connector 301 and the sub-connector 302 are respectively locked and connected to the pipe 1 to be connected, so that the female connector 301, the sub-connector 302 and the pipe 1 to be connected can be quickly connected and installed, thereby realizing a quick connection between the pipes 1 to be connected, and greatly improving the installation efficiency.

[0041] Specifically, Figure 5 As shown, the reinforcement connection mechanism 4 includes a mounting hole 401, a reinforcement screw 402 and a reinforcement nut 403. The multiple mounting holes 401 are respectively opened on the side wall of the flange 2. The reinforcement screw 402 is movably arranged between the two flanges 2 and movably connected to the mounting hole 401. The two reinforcement nuts 403 are respectively threadedly connected to the two ends of the reinforcement screw 402, and the side wall of the reinforcement nut 403 is in contact with the flange 2.

Clamping grooves 11 are opened on the side walls at both ends of the reinforcing screw 402, and the limit screw 10 is in contact with the clamping groove 11.

[0043] First, place the limit ring 9 on one side of the mounting hole 401, so that the reinforcement screw 402 passes through the two limit rings 9 while passing through the mounting hole 401. The limit ring 9 can be limited by the limit screw 10. The setting of the limit ring 9 can adjust the position of the reinforcement screw 402 between the two flanges 2. Then, the reinforcement screw 402 is installed by the reinforcement nut 403. At this time, the reinforcement nut 403 firmly clamps the two flanges 2 together, thereby enhancing the stability and reliability of the connection between the pipes 1 to be connected and reducing the risk of leakage.

[0044] By adopting the above technical solution, the problem that the existing water supply and drainage pipe connecting joints cannot achieve quick connection and installation between two pipes 1 to be connected is solved. The existing drainage pipe connecting joints do not connect the female joint 301 and the sub-joint 302 with the drainage pipe, and there is a problem of falling off and poor sealing between the drainage pipe and the female joint 301 or the sub-joint 302.

[0045] Working principle: When the present application is in use, firstly, the female connector 301 and the sub-connector 302 are respectively sleeved on the ports of the two sections of the pipe 1 to be connected. At this time, the positioning strip 5 on the side wall of the sub-connector 302 is movably connected with the positioning groove 6 on the side wall of the pipe 1 to be connected, ensuring the correct alignment of the sub-connector 302 and the pipe 1 to be connected. The plug ring 303 on the side wall of the female connector 301 and the slot 304 on the side wall of the sub-connector 302 are adapted to each other to achieve the preliminary connection between the two sections of the pipe 1 to be connected. The T-shaped block 307 on the fixing ring 1 305 is movably connected with the through hole 308 and the slide groove 309 on the fixing ring 2 306. By rotating the female connector 301 to slide the T-shaped block 307, the female connector 301 and the sub-connector 302 are tightly fitted and installed. The mounting ring 310 is fixed with the locking bolt 311, and the two mounting rings 310 are respectively fixedly connected to the side walls of the female connector 301 and the sub-connector 302. By rotating the locking bolt 311 to pass through the mounting ring 310 and the middle of the flange 2, the female connector 301 and the sub-connector 302 are respectively locked and connected to the pipe 1 to be connected, thereby enabling the female connector 301, the sub-connector 302 and the pipe 1 to be connected to be quickly connected and installed, thereby achieving a quick connection between the pipes 1 to be connected and greatly improving the installation efficiency. Then, the flanges 2 can be firmly clamped together by the reinforcing screw 402 and the reinforcing nut 403, thereby enhancing the stability and reliability of the connection between the pipes 1 to be connected and reducing the risk of leakage.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
