Technical Field

[0001] The utility model relates to the technical field of pipe connectors, and particularly relates to a pipe connector for water supply and drainage. Background Technique

[0002] A pipeline is a device formed by connecting pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. A pipe connector is a commonly used fitting in pipelines for connecting different pipes so that the liquid in the pipeline can flow into other pipelines through the pipe connector.

[0003] In the existing water supply and drainage pipelines, the connection between pipelines is usually achieved by bolts and flanges, which requires frequent screwing of bolts, is time-consuming and laborious, and has low efficiency. When there is a problem with the pipeline, it is necessary to screw each bolt one by one, which is inconvenient for disassembly or replacement and is relatively inconvenient to use.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model is a pipe connector for water supply and drainage, including a connecting pipe 1, both ends of the connecting pipe 1 are fixedly installed with connecting tubes 2, the two connecting tubes 2 are symmetrically arranged and are connected to the connecting pipe 1, the two connecting tubes 2 are rotatably installed with a driving disk 3, a plurality of clamping rods 4 are rotatably installed on the driving disk 3, and a clamping wheel 5 is fixedly installed on one end of the plurality of clamping rods 4 close to each other, a paddle 6 is fixedly installed on the driving disk 3, a rotating groove 13 for the paddle 6 to rotate is provided on the connecting tube 2, each clamping rod 4 is provided with a slide groove 7, a connecting rod 8 is slidingly arranged in the slide groove 7, and the connecting rod 8 is fixed to the driving disk 3. The connection is fixed, and a locking assembly 9 for fixing the position of the paddle 6 is provided on the connecting tube 2. A channel for the pipe to pass through is opened in the connecting tube 2. The paddle 6 is turned to drive the driving disk 3 to rotate. The driving disk 3 rotates and drives the clamping rod 4 to rotate under the cooperation of the connecting rod 8 and the slide groove 7. The rotation of the clamping rod 4 drives the clamping wheel 5 to follow the rotation, so that the plurality of clamping wheels 5 are close to each other, so that the pipe inserted into the connecting tube 1 can be clamped and fixed. When it is necessary to release the fixation of the pipe, the paddle 6 is reversely turned to make the plurality of clamping wheels 5 move away from each other, that is, the fixation of the pipe can be released. The operation is simple, the use is convenient, and it is easy to install and disassemble.

[0025] Among them, a plurality of clamping rods 4 are evenly distributed in an array along the circumference, and the number of the clamping rods 4 is not less than three, which can further improve the clamping and fixing effect of the clamping wheel 5 on the pipe.

[0026] Among them, the locking assembly 9 includes a positioning screw 91 threadedly installed on the paddle 6 and a connecting ring 92 fixedly installed on the outer surface of the connecting tube 2. The connecting ring 92 is provided with a plurality of threaded holes 93 used to cooperate with the positioning screw 91. After the clamping and fixing is completed, the positioning screw 91 on the paddle 6 is screwed into the corresponding threaded hole 93 to lock the position of the paddle 6 to ensure the stability of the position of the paddle 6 after clamping and fixing, thereby ensuring that the clamping wheel 5 can stably clamp and fix the pipe, and the clamping stability is good.

[0027] Among them, the outer surface of the clamping wheel 5 is fixedly installed with an anti-skid pad 10. By providing the anti-skid pad 10, the friction between the clamping wheel 5 and the pipe 1 to be connected can be increased, and the stability of clamping and fixing the pipe can be further improved.

[0028] Wherein, sealing gaskets 11 are fixedly installed at both ends of the connecting pipe 1, and the sealing gaskets 11 can improve the sealing effect when the connecting pipe 1 is connected with the pipe 1 to be connected.

[0029] Among them, the ends of several connecting rods 8 are fixedly installed with the same limit plate 12. By setting the limit plate 12, the stability of the connection between the connecting rod 8 and the clamping rod 4 can be ensured, and the connection rod 8 and the clamping rod 4 can be prevented from being separated.

[0030] When working, the pipe to be connected is inserted into the connecting tube 2 and the connecting tube 1 and connected with the connecting tube 1, and the paddle 6 is toggled to drive the driving disk 3 to rotate. The driving disk 3 rotates and drives the clamping rod 4 to rotate under the cooperation of the connecting rod 8 and the slide groove 7. The rotation of the clamping rod 4 drives the clamping wheel 5 to rotate accordingly, so that the plurality of clamping wheels 5 are close to each other, so that the pipe inserted into the connecting tube 1 can be clamped and fixed. After the fixing is completed, the positioning screw 91 on the paddle 6 is screwed into the corresponding threaded hole 93 to lock the position of the paddle 6 to ensure the stability of the position of the paddle 6 after clamping and fixing, thereby ensuring the stable clamping and fixing of the pipe by the clamping wheel 5, and the clamping stability is good. When it is necessary to release the fixation of the pipe, the positioning screw 91 is screwed out from the threaded hole 93 on the same side, and then the paddle 6 is toggled in the opposite direction to make the plurality of clamping wheels 5 move away from each other, that is, the fixation of the pipe can be released. The operation is simple, the use is convenient, and the connection and disassembly of the pipe are convenient.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
