[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 3, the utility model provides an embodiment: a waterproof connector, including a shell 1, a connecting pipe 2 is fixedly connected to one side of the shell 1, a connecting frame 3 is slidably connected to the inside of the shell 1, the top of the connecting frame 3 is fixedly connected to a docking plate 4, one side of the docking plate 4 is fixedly connected to a fixing column 5, the fixing column 5 is slidably connected to the inside of the shell 1, the outer wall of the fixing column 5 is sleeved with a spring 6, the inside of the shell 1 is rotatably connected to a rotating column 7, the top of the outer wall of the rotating column 7 is fixedly connected to a turntable 8, pulleys 9 are provided on both sides of the turntable 8, and the pulleys 9 are connected to the docking The plates 4 touch each other, and a sealing frame 10 is fixedly connected to one side of the connecting frame 3. A docking assembly is provided between the sealing frames 10. One end of a spring 16 is fixedly connected to one side of the docking plate 4, and the other end of a spring 16 is fixedly connected to the inside of the housing 1. The docking assembly includes a docking column 11, which is fixedly connected to the outer wall of the sealing frame 10 on one side, and the docking column 11 is slidably connected to the inside of the sealing frame 10 on the other side. A magnet 12 is provided inside the docking column 11, and a magnet 2 13 is provided inside the sealing frame 10 on the other side. Magnet 12 and magnet 2 13 are magnetically attracted to each other;

[0031] Specifically, when inserting a new connector, in order to effectively reduce the wear of the sealing ring due to multiple reciprocating plug-ins, especially to avoid accelerated aging of the sealing ring due to friction, a delicate operation process can be used to ensure the sealing and durability. First, the operator can rotate the turntable 8 around the rotating column 7. At this time, the rotation of the turntable 8 will drive the pulley 9 to apply an extrusion force to the docking plates 4 on both sides. This extrusion force causes the docking plates 4 to start sliding under the constraint of the fixed column 5. At the same time, the spring 6 is gradually compressed due to the extrusion force. In this process, the sealing frame 10 will be pulled by the connecting frame 3 driven by the docking plate 4, and then the sealing frames 10 on both sides are separated. At this time, the insertion operation of the connector becomes convenient and smooth. The operator can easily insert the connector into the corresponding socket without resistance. When the connector is successfully inserted and is in the predetermined position, the operator can release the turntable 8 and no longer apply external force to it. At this time, the compressed spring 6 will quickly release its own accumulated elastic potential energy. Reset, this potential energy release causes the docking plate 4 to return to its original working position together with the connecting frame 3. As the docking plate 4 is reset, the turntable 8 is also driven to rotate by the rotating column 7 and the pulley 9 to ensure that the entire device returns to its original state. During this reset process, the sealing frames 10 on both sides are closed again, and the docking column 11 carried by the sealing frame 10 will be accurately inserted into the sealing frame 10 on the other side to achieve preliminary docking and locking. In addition, the magnetic attraction between magnet 12 and magnet 2 13 in the sealing frame 10 further enhances the joining strength between the sealing frames 10 on both sides. This magnetic attraction not only ensures the tight docking between the sealing frames 10, but also greatly improves the stability and reliability of the sealing device. Through the precise operation of the above steps, not only the wear of the sealing ring is effectively reduced and the service life of the device is extended, but also the operational convenience and final sealing effect during the joint insertion process are ensured. This design fully takes into account the reliability and durability of the structure, and ensures the long-term sealing performance of the system under high-intensity use environments.

[0032] Reference Figure 4 , the inside of the shell 1 is fixedly connected with a connector 15, the outer wall of the connector 15 is slidably connected with a sealing plate 14, the outer wall of the sealing plate 14 fits with the shell 1, and one side of the sealing plate 14 is fixedly connected with a fixing column 2 16, the fixing column 2 16 is slidably connected to the inside of the shell 1, and the outer wall of the fixing column 2 16 is sleeved with a spring 2 17, one end of the spring 2 17 is fixedly connected to one side of the sealing plate 14, and the other end of the spring 2 17 is fixedly connected to the inside of the shell 1, a sponge ring 18 is provided on one side of the sealing plate 14, and the sponge ring 18 is sleeved on the outer wall of the connector 15, one end of the spring 16 is fixedly connected to one side of the docking plate 4, and the other end of the spring 16 is fixedly connected to the inside of the shell 1;

[0033] Specifically, when the connector is inserted into the shell 1, the entire system will undergo a delicate movement process to ensure the reliability of the connection and the integrity of the seal. First, as the connector gradually enters the shell 1, it will first apply pressure to the sealing plate 14. The sealing plate 14 begins to move under the push of the connector, driving the fixed column 2 16 to slide along the guide groove inside the shell 1. At this stage, the spring 2 17 is subjected to the extrusion force from the connector and is gradually compressed. The compression of the spring not only stores elastic potential energy, but also provides a driving force for the subsequent reset action. At the same time, the displacement of the sealing plate 14 will also cause the sponge ring 18 to move along the fixed column 2 16. During this process, the sponge ring 18 gently wipes the surface of the connector. This design not only ensures the cleanliness of the connector surface, but also lays the foundation for the subsequent sealing action. At this time, the connector 15 can smoothly complete the docking operation with the connector. , ensuring the stability and accuracy of the mechanical connection. During the insertion of the connector, the wiping action of the sponge ring 18 can effectively remove tiny particles or dirt that may exist on the surface of the connector, thereby improving the contact quality between the connector 15 and the connector. This design with self-cleaning function greatly improves the reliability of the system and ensures that the connector can remain in good condition during each plugging and unplugging process. When the connector is pulled out from the housing 1, the spring 2 17 will gradually release its own elastic potential energy, pushing the sealing plate 14 back to its initial position. As the sealing plate 14 is reset, the sponge ring 18 also returns to its original position, and at the same time cleans up the dirt or liquid that may remain after the connector is pulled out, further ensuring the cleanliness of the connector and the sealing of the interface. Finally, the returning action of the sealing plate 14 enables the connection to be resealed, thereby preventing dust or liquid in the external environment from entering the connector, ensuring the long-term stability and sealing effect of the entire system.

[0034] Working principle: When a new joint needs to be inserted, in order to avoid repeated reciprocating plug-in and causing the sealing ring to age due to friction, we can rotate the turntable 8 to make it rotate with the rotating column 7 as the axis, and then let the pulley 9 squeeze the docking plates 4 on both sides, so that it can slide under the restriction of the fixed column 5, and at the same time make the spring 16 be squeezed. At this time, the sealing frames 10 on both sides will be pulled by the connecting frame 3 driven by the docking plate 4 and then separated. At this time, we can insert the joint normally. After insertion, release the position of the turntable 8. At this time, the squeezed spring 16 will release its own elastic potential energy, so that the docking plate 4 and the connecting frame 3 return to their original position. At this time, the rotating column 7 is driven by the turntable 8 that is rotated by the pulley 9 pushed by the docking plate 4, and the sealing frames on both sides are The sealing frame 10 is re-docked. At this time, the docking column 11 carried by the sealing frame 10 on one side is inserted into the sealing frame 10 on the other side, and magnetic attraction is generated between magnet 1 12 and magnet 2 13, further stabilizing the docking between the sealing frames 10, thereby achieving sealing. At the same time, when the joint is inserted into the outer shell 1, it will first squeeze the sealing plate 14, so that the fixing column 2 16 slides along the inside of the outer shell 1, and at the same time squeezes the spring 2 17. At this time, the sealing plate 14 and the sponge ring 18 are displaced along the fixing column 2 16, and the connecting head 15 is successfully docked with the joint. The sponge ring 18 also successfully wipes the connecting head 15. After the joint is pulled out, the spring 2 17 will release its own elastic potential energy, so that the sealing plate 14 is pushed back to its original position, thereby sealing the connection.
