The prefabricated components and parts are used in the factory and then assembled and installed on site. Among them, prefabricated building pipes are important components. They exist in gas, hot water supply projects and building fire water supply. During installation, a type of connector is required.

[0003] After searching, the Chinese patent announcement number is: CN216692561U, which discloses a connector for prefabricated building pipes based on BIM technology, including a connecting pipe, one side of the inner wall of the connecting pipe is slidably connected to a pipe 1, the inner wall of the connecting pipe is slidably connected to a spring plate, the outer end of the spring plate is fixedly installed with a spring rod, one end of the spring rod is fixedly installed with a clamping block, the outer end of the pipe 1 is provided with a fixing groove for the clamping block, the outer end of the spring rod is slidably connected to a fixing spring, one end of the fixing spring is fixed to the outer end of the spring plate The fixing spring is fixedly installed, and the other end of the fixing spring is fixedly installed with the inner wall of the connecting pipe. The application connects the pipe 1 to the inside of the sliding connection pipe and squeezes it inward, so that the pipe 1 squeezes the clamping block into the inside of the connecting pipe. The force generated by the stretched fixing spring causes the clamping block to be clamped with the fixing groove at the outer end of the pipe 1, so that the pipe 1 and the connecting pipe are fixed. However, in actual use, the connector is clamped by multiple clamping blocks, so that the pipe cannot be well sealed when connected, resulting in fluid or gas leakage, thereby reducing the connection effect of the connector. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a connector for prefabricated building pipes, aiming to improve the problem in the prior art that the pipes cannot be well sealed when connected and fluid or gas leakage may occur, thereby reducing the connection effect of the connector.

[0014] A rubber plate is fixedly mounted on the top wall of the shell, and the top wall of the rubber plate is smooth.

[0015] Through the above technical solution, the top shell can be protected, thereby reducing the possibility of damage.

[0016] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The locking mechanism further comprises a plurality of rubber pads, the inner walls of which are respectively fixedly connected to the middle portions of the corresponding threaded knobs.

[0021] The above technical solution reduces the rotation damage of the threaded knob to the locking plate.

[0027] Through the above technical solution, the static friction of the paddle is increased, thereby improving the anti-slip effect of the paddle.

[0028] The utility model has the following beneficial effects:

[0029] In the utility model, through the access of the right water pipe, the push rod pushes the driving rod to move, thereby driving the gear seat driving gear to rotate, and then the threaded rod drives the sealing top plate to move downward under the restricted rotation of the sliding column, so that the sealing bottom plate and the sealing top plate clamp and seal the pipeline, thereby improving the sealing effect of the connection between the two pipelines, thereby reducing the possibility of fluid or gas leakage when the pipeline is in use, and thus improving the connection effect of the connecting piece.
