Description

Technical Field

[0001] The utility model relates to the technical field of bellows connectors, in particular to a PVC bellows clip connector. Background Art

[0002] The purpose of connecting PVC corrugated pipes with fittings is to ensure the integrity and sealing of the piping system, preventing liquid or gas leakage, while also providing flexibility and adaptability to suit different installation environments and conditions. Fittings also enhance the pressure resistance and durability of the pipes, enabling them to withstand various external pressures and environmental influences.

[0003] After extensive searching, the publication number CN201462289U disclosed a polyethylene bellows sealing connector, which utilizes a rubber flange to fit onto the outer wall of the bellows, which not only seals the pipe but also secures it by buckling and pulling the connected pipe.

[0004] However, the connectors in the existing technology have a relatively simple structure when in use, and in order to achieve a perfect fit, there is basically no gap between the connector and the corrugated pipe, which results in greater resistance when being fitted onto the corrugated pipe, making it difficult to fit quickly, resulting in a long time spent on docking the corrugated pipe. Therefore, a PVC corrugated pipe snap-on connector is needed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a PVC corrugated pipe clip connector, which has the advantages of increasing installation speed and reducing the time spent on pipe docking, and solves the problem in the prior art that connectors are time-consuming to install and inconvenient to assemble.

[0007] The snap-fit ​​buckle includes an inner tube and an outer tube. The inner side of the inner tube is provided with anti-slip grooves. The outer side of the inner tube is fixedly installed with limiting strips in a circular array. The side of the limiting strips facing away from the inner tube contacts the inner wall of the outer tube but is not fixedly connected.

[0008] Preferably, the sleeve is designed with a soft rubber material, and the top of the sleeve is provided with a ring-shaped array of limit grooves that extend vertically through the sleeve. The sleeve height matches the height of the plug-in tube. The sleeve is designed with a soft rubber material to ensure that it maintains good flexibility and sealing under various temperature conditions. The top of the sleeve is designed with a ring-shaped array of limit grooves that extend vertically through the sleeve, providing additional stability and fixing points for the installation of other components.

[0012] Preferably, the outer tube is designed with a soft rubber material, and a mounting groove is provided on the outer wall of the outer tube. The clamp is movably mounted on the outer side of the outer tube through the mounting groove. A positioning groove for limiting the clamp is provided in the mounting groove, and the inner wall of the outer tube does not contact the outer wall of the sleeve. In the design, the outer tube is designed with a soft rubber material to ensure that it can maintain good flexibility and sealing under various temperature conditions. A mounting groove is designed on the outer wall of the outer tube, and the clamp is movably mounted on the outer side of the outer tube through the mounting groove, providing additional fastening force for the connector. A positioning groove for limiting the clamp is also specially designed in the mounting groove to ensure accurate positioning of the clamp. In addition, the inner wall of the outer tube does not contact the outer wall of the sleeve. This design reduces friction and increases the service life of the connector.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The snap-on clip in this utility model can be flexibly inserted into the top of the pipe. This design allows for quick assembly and disassembly, eliminating the need for complex fixing or disassembly procedures. Because the snap-on clip is flexibly installed, it can be quickly positioned when docking the pipes. The anti-slip grooves on the inside of the inner pipe provide additional friction, ensuring that the pipes do not slip or shift during installation. This facilitates quick and accurate pipe alignment, reducing adjustment and repositioning time. The limit bar is fixedly mounted on the outside of the inner pipe and contacts the inner wall of the outer pipe but is not fixedly connected. This design allows for flexibility during installation while providing the necessary fixation and support to ensure stability during the docking process. The outer diameter of the plug-in tube is smaller than the inner diameter of the sleeve. This size combination allows for easy insertion of the plug-in tube into the sleeve, reducing the resistance and force required during installation. The clamp allows for quick locking. The clamp flexes onto the outside of the outer pipe through a mounting groove on the outer wall of the outer pipe and is fixed in place by a positioning groove. This design allows the user to quickly tighten the clamp to quickly fix the two pipes. The design that the inner wall of the outer pipe does not contact the outer wall of the sleeve reduces friction, which helps to reduce resistance during installation and makes the pipe docking smoother, thus saving time. The entire connector adopts a modular design and the various components can be quickly assembled and disassembled, which means that when replacement or maintenance is needed, it can be carried out quickly without dismantling the entire piping system. Through these design features, the PVC corrugated pipe clamp connector can achieve fast and easy installation, reducing time consumption and labor intensity during installation, improving work efficiency, and also ensuring the firmness and sealing of the connection.
