[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this utility model.

[0019] Example

[0020] See also Figure 1-Figure 4 The figure shows a pipe connector for a PVC pipe that is easy to install, including a connector 1, a connecting pipe 2 is provided on one side of the connector 1, fixed brackets 3 are provided at both ends of the connector 1, sliding blocks 4 are provided on the inner side of the fixed bracket 3, the sliding block 4 is slidably connected to the limit rod 5, a locking block 6 is provided on one side of the limit rod 5, a clamp 7 is provided under the locking block 6, a density ring 8 is provided inside the connector 1, and a sealing gasket 9 is provided at the central axis of the connector 1. The utility model provides fixed brackets at both ends of the connector, a slidable sliding block is provided on the inner side of the fixed bracket, the sliding block is slidably connected to the limit rod, and a density ring is provided inside the connector, so as to effectively prevent the fluid from leaking through the connection, enhance the sealing performance, and prevent displacement or loosening due to external force.

[0021] Furthermore, the density ring 8 is fixedly connected to the inner wall of the connector 1, and density rings 8 are provided on both sides of the density ring 8. The double density ring design greatly enhances the sealing effect of the pipeline connection. When the fluid in the pipeline passes through the connection, the density rings on both sides can form two barriers to effectively prevent fluid leakage. At the same time, this design can also reduce the risk of sealing failure caused by pipeline vibration or temperature changes, ensuring the long-term stable operation of the pipeline system.

[0022] Furthermore, both ends of the connector 1 are provided with a central axis symmetrical fixed bracket 3, the inner side of the fixed bracket 3 is provided with a sliding groove, and the sliding groove is slidably connected to the sliding block 4. The central axis symmetrical fixed bracket design ensures that the connector can maintain balance when subjected to the fluid pressure inside the pipeline.

[0023] Furthermore, a connecting shaft 401 is provided inside the sliding block 4, and the connecting shaft 401 is rotatably connected to the limit rod 5. A connecting block 402 is provided on the bottom surface of the sliding block 4, and the connecting block 402 is fixedly connected to the clamp 7. The connecting shaft provided inside the sliding block allows the limit rod to be connected to it in a rotatable manner, and can freely adjust the angle within a certain range, thereby reducing friction and resistance during the installation process, making the installation process smoother.

[0024] Furthermore, the middle part of the limit rod 5 is rotatably connected to the fixed bracket 3, one end of the limit rod 5 is rotatably connected to the connecting shaft 401, and the other end of the limit rod 5 is tightly pressed into the locking block 6. The middle part of the limit rod is rotatably connected to the fixed bracket. The design of the rotatable connection allows the limit rod to rotate freely within a certain range, thereby being able to adapt to the pipeline connection requirements of different angles and positions.

[0025] Furthermore, the locking block 6 includes a base 601 and a buckle 602. The base 601 is fixedly connected to the top of the sliding block 4, and the buckle 602 is snap-fitted to one end of the limiting rod 5. The locking block is tightly combined with the base and the sliding block to ensure that when the limiting rod moves to a predetermined position, the buckle can be quickly and accurately snapped into place, and the limiting rod is firmly locked on the connecting head, which can effectively prevent the pipeline from loosening or falling off due to vibration or impact during operation.

[0026] In this solution, the working process is: first, fix the sealing gasket on the inner wall of the connector, then fix the sealing ring on both sides of the sealing gasket, then fix the connecting pipe with a clamp, then rotate the limit rod to make its sliding block move back and forth horizontally along the internal slide groove of the fixed bracket, and make the other end of the limit rod release the limit block to complete the socket insertion.
