[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a construction connection device for water supply and drainage pipes, including a pipe body 1. The pipe body 1 includes an insertion part 2 and a plug-in part 3. The inner ring of the insertion part 2 is provided with a conical groove 4. The plug-in part 3 is provided with an external thread 5. The inner ring of the conical groove 4 is provided with an internal thread 6 that matches the external thread 5. The pipe body 1 is provided with an arc plate 7 for increasing the connection strength, a movable ring 8 for driving the arc plate 7, and a limiting ring 9 for locking the movable ring 8 from left to right. The arc plate 7 is provided with a flexible material for absorbing and reducing vibration energy. By setting the arc plate 7, the movable ring 8 and the limiting ring 9, it is convenient to strengthen the connection strength of two adjacent water supply and drainage pipes, and the installation and disassembly are relatively quick and convenient.

[0022] The number of the arc plates 7 is four, and the four arc plates 7 are arranged at equal intervals around their circumferences on the joint between adjacent pipe bodies 1.

[0023] An annular block 10 is fixedly connected to the main body of the pipe 1, and a transmission block 11 is arranged around the circumference of the main body of the pipe 1. A first transmission rod 12 and a second transmission rod 13 are arranged on the transmission block 11.

[0024] The two ends of the first transmission rod 12 are hinged to the annular block 10 and the transmission block 11, respectively, and the two ends of the second transmission rod 13 are hinged to the transmission block 11 and the movable ring 8, respectively.

[0025] A connecting rod 14 is provided on the transmission block 11. The end of the connecting rod 14 away from the transmission block 11 is fixedly connected to the arc plate 7. By setting the first transmission rod 12, the second transmission rod 13 and the connecting rod 14, it is convenient to drive multiple arc plates 7 to move towards the pipe joint at the same time.

[0026] The movable ring 8 is provided with an elastic block 15, the limiting ring 9 is provided with a circular groove, and the limiting ring 9 is provided with a positioning hole that matches the elastic block 15.

[0027] The movable ring 8 is provided with a relief groove 16 that is adapted to the elastic block 15. A spring 17 is provided in the relief groove 16. The two ends of the spring 17 are fixed to the inner wall of the relief groove 16 and the elastic block 15, respectively. By setting the elastic block 15, the spring 17 and the relief groove 16, it is easy to lock the movable ring 8 with the limit ring 9, so that the arc plate 7 maintains a continuous and stable connection with the water supply and drainage pipe. Thus, the construction connection device for water supply and drainage pipes can enhance the connection strength of the threaded connection of water supply and drainage pipes.

[0028] Working principle: The installer first inserts the insertion part 3 of one pipe body 1 into the insertion part 2 of the adjacent pipe body 1. Then, one of the pipe bodies 1 is rotated to connect the two pipe bodies 1 by threads. Then, the movable ring 8 is manually pushed and inserted into the circular groove on the limiting ring 9. During this process, the first transmission rod 12 and the second transmission rod 13 move, driving the transmission block 11 to move towards the center of the cross-section of the pipe body 1. This causes the connecting rod 14 to drive the arc plate 7 to move towards the surface of the water supply and drainage pipe. When the arc plate 7 reaches the joint of the two pipe bodies 1, the elastic material on the arc plate 7 is in close contact with the joint. At the same time, the elastic block 15 always tends to face outward. The elastic block 15 extends out and penetrates the positioning hole on the limiting ring 9. Thus, the installation of the water supply and drainage pipe is completed. When disassembling, the elastic block 15 is held down and the movable ring 8 is moved in the opposite direction to release the pressure of the arc plate 7 on the pipe body 1. Then, the two pipe bodies 1 can be disassembled by rotating in the opposite direction. Thus, this water supply and drainage pipe construction connection device can enhance the connection strength of the threaded connection of the water supply and drainage pipe.

[0029] The mechanisms, components, and parts in this utility model that are not specifically described are all existing structures that already exist in the prior art and can be purchased directly from the market.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
