[0003] The existing drainage pipes generally connect two drainage pipes by means of the threaded connection of the drainage pipes themselves. This method requires one of the pipes to be rotated, which makes the connection between the pipes more laborious. When a pipe is damaged, it is also more laborious to disassemble it. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] See also Figure 1-3, a pipe connecting device for water supply and drainage, comprising a connecting pipe 1, a rubber ring 2 is fixedly arranged in the middle of the pipe body of the connecting pipe 1, and limiting rings 3 are symmetrically fixedly arranged on both sides of the rubber ring 2 in the connecting pipe 1, and a plurality of elastic pressing pieces 4 are fixedly arranged on the side of the limiting ring 3 close to the port of the connecting pipe 1, and the plurality of elastic pressing pieces 4 are arranged in a ring array, and a driving component for driving the plurality of elastic pressing pieces 4 to be synchronously pressed toward the center of the connecting pipe 1 is also provided on the connecting pipe 1. By arranging the rubber ring 2, the limiting ring 3, the elastic pressing piece 4 and the driving component, when connecting two pipes, it is only necessary to insert the two pipes into the two ports of the connecting pipe 1, and then by controlling the driving component, the plurality of elastic pressing pieces 4 on the side of the limiting ring 3 are synchronously moved toward the pipe, so that the fixed connection of the two pipes can be quickly realized without rotating the pipe, which has the advantages of convenient connection, time saving and labor saving, and at the same time, it is also convenient for rapid disassembly of the two pipes and convenient for replacement of the pipes.

[0019] Among them, the driving assembly includes a movable sleeve 5, a connecting piece 6, a movable ring 7 and a power unit. The movable ring 7 is movably sleeved on the connecting pipe 1 through the power unit, and the inner wall of the movable ring 7 is installed with the movable sleeve 5 through multiple connecting pieces 6. The cross-section of the elastic pressing piece 4 is wedge-shaped. The movable sleeve 5 is slidably arranged in the connecting pipe 1, and the end of the movable sleeve 5 is movably inserted between the elastic pressing piece 4 and the inner wall of the connecting pipe 1. The side wall of the connecting pipe 1 is also arranged with a plurality of strip holes 8 for the sliding of the connecting piece 6.

[0020] Preferably, the power unit includes a driving ring 9 fixedly mounted on one side of the movable ring 7, the driving ring 9 is threadedly sleeved on the connecting pipe 1, and anti-slip grooves 10 are provided on the outer wall of the driving ring 9. The setting of the power unit utilizes threaded propulsion to promote the horizontal movement of the movable ring 7, and has the advantages of simple structure and low cost.

[0021] Specifically, after the two pipes are inserted into the two ends of the connecting pipe 1, the two driving rings 9 on the connecting pipe 1 are rotated. During the process, the two driving rings 9 drive the two movable rings 7 to be relatively close to each other, and the movable sleeve 5 connected to the driving ring 9 is gradually inserted between the elastic pressing piece 4 and the inner wall of the connecting pipe 1. Since the cross-section of the elastic pressing piece 4 is wedge-shaped, multiple elastic pressing pieces 4 will gradually move closer to the pipes and press them tightly, thereby fixing the two pipes. Conversely, when the two pipes need to be disassembled, it is only necessary to rotate the driving ring 9 in the opposite direction.

[0022] In addition, the two ends of the rubber ring 2 are symmetrically provided with inclined bevels 11. With such a configuration, when the ports of the two pipes are against the two sides of the rubber ring 2, the two sides of the rubber ring 2 will be stuck in the ports of the pipes, thereby improving the sealing of the connection between the two pipes.

[0023] Furthermore, positioning bolts 12 are symmetrically threadedly installed on the pipe body of the connecting pipe 1 near the two end ports. Two single-side positioning bolts 12 are provided, and the two positioning bolts 12 are symmetrically installed at both ends of the connecting pipe 1 in the diameter direction. The setting of the positioning bolts 12 can perform preliminary positioning of the pipe after the pipe is inserted into the connecting pipe 1. During the process of rotating the driving ring 9, the phenomenon of the pipe being pulled out of the connecting pipe 1 and causing the connection end to be loose is avoided, which further facilitates the connection of the two pipes.

[0024] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
