[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example: Reference Figures 1 to 4A connector with good locking effect includes a first buffer groove on the front of the connector, a first sealing ring movably connected to the inner wall of the first buffer groove, a first threaded groove on the inner wall of the connector, a second buffer groove on the inner wall of the first threaded groove, a second sealing ring movably connected to the inner wall of the second buffer groove, an adapter tube movably connected to the front of the connector, one end of the adapter tube having a threaded tube, the surface of the threaded tube having a first threaded groove threaded to it, a limit groove on the surface of the connector, a first limit plate movably connected to the inner wall of the limit groove, a third buffer groove on the front of the first limit plate, and a third sealing ring movably connected to the inner wall of the third buffer groove. In this device, the front of the connector 1 has a first buffer groove, and a first sealing ring 2, made of rubber, is fitted inside the first buffer groove. Inside the connector 1 is a second buffer groove, and a second sealing ring 7, also made of rubber, is fitted inside the second buffer groove. Screw the threaded tube 5 clockwise into the internal thread of the connector 1, causing one end of the threaded tube 5 to compress the first sealing ring 2, deforming the first sealing ring 2 and filling the first buffer groove. Then, bring the adapter tube 4 close to the front of the connector 1 through the threaded tube 5, causing the adapter tube 5 to compress the second sealing ring 3, deforming the second sealing ring 3 and filling the second buffer groove. There is a first limiting plate 6 on the inner wall of the threaded sleeve 8, and a third buffer groove on the front of the first limiting plate 6. A third sealing ring 7, made of rubber, is fitted inside the third buffer groove. The adapter tube 5 has threads on its surface. Screw the threaded sleeve 8 counterclockwise into the surface threads of the adapter tube 5 and tighten it. There is a limiting groove on the surface of the connector 1. Bring the first limiting plate 6 close to the inner wall of the limiting groove, causing the inner wall of the limiting groove to compress the third sealing ring 7, filling the third buffer groove. This increases the sealing performance of the adapter tube 5 when connected to the connector 1, preventing gas and dust from entering. The inner wall of the threaded collar is threaded with an adapter tube. The inner wall of the adapter tube has a groove, and a pipe is movably connected to the inner wall of the groove. A retaining ring is inserted into the surface of the pipe. There is a groove inside the adapter tube 4, and a pipe 9 is inside the groove. A retaining ring 10 is fitted on the surface of the pipe 9. The retaining ring 10 is conical in shape, so that the surface of the retaining ring 10 is embedded in the groove. There are threads on the surface of the adapter tube 4. A nut 12 is screwed clockwise into the threads on the surface of the adapter tube 4 and tightened. There is a second limiting plate 11 on the inner wall of the nut 12. The nut 12 causes the second limiting plate 11 to abut against one end of the retaining ring 10 and push the retaining ring 10 so that the tip of the retaining ring 10 is inserted into the pipe 9, which facilitates fixing the pipe 9 inside the adapter tube 4 and prevents the pipe 9 from shifting.One end of the adapter tube is provided with a threaded tube, and the surface of the threaded tube is threaded with a first threaded groove. The inner wall of the threaded collar is threaded with the adapter tube, and the inner wall of the nut is threaded with the adapter tube. The threaded tube 5 is screwed clockwise into the internal thread of the connector 1. The surface of the adapter tube 5 is threaded. The threaded collar 8 is screwed counterclockwise into the surface thread of the adapter tube 5 and tightened. The surface of the adapter tube 4 is threaded. The nut 12 is screwed clockwise into the surface thread of the adapter tube 4 and tightened. There is a limit groove on the surface of the connector 1. The first limit plate 6 restricts the movement of the threaded collar 8 in the limit groove, so that the rotation direction of the threaded collar 8 and the threaded tube 5 are opposite, which facilitates a more stable connection during threaded connection and prevents vibration.
[0019] The working principle of this device is as follows: The front of connector 1 has a first buffer groove. A first sealing ring 2, made of rubber, is fitted inside the first buffer groove. Inside connector 1 is a second buffer groove, and a second sealing ring 7, also made of rubber, is fitted inside the second buffer groove. The threaded tube 5 is screwed clockwise into the internal threads of connector 1, causing one end of the threaded tube 5 to compress the first sealing ring 2, deforming it and filling the first buffer groove. The adapter tube 4 is then brought close to the front of connector 1 through the threaded tube 5, causing the adapter tube 5 to compress the second sealing ring 3, deforming it and filling the second buffer groove. A first limiting plate 6 is located on the inner wall of the threaded sleeve 8. A third buffer groove is located on the front of the first limiting plate 6, and a third sealing ring 7, made of rubber, is fitted inside the third buffer groove. The surface of the adapter tube 5 has threads. The threaded sleeve 8 is screwed counterclockwise into the surface threads of the adapter tube 5 and tightened. A limiting groove is located on the surface of connector 1, allowing the first limiting plate 6 to approach the inner edge of the limiting groove. The inner wall of the limiting groove is pressed against the third sealing ring 7, causing the third sealing ring 7 to fill the third buffer groove. Inside the adapter tube 4, there is a groove, and inside the groove, there is a pipe 9. A retaining ring 10 is fitted onto the surface of the pipe 9. The retaining ring 10 has a cone-shaped structure, allowing its surface to embed into the groove. The adapter tube 4 has threads, and a nut 12 is screwed clockwise into these threads and tightened. Inside the nut 12, there is a second limiting plate 11. The nut 12 causes the second limiting plate 11 to abut against one side of the retaining ring 10. Push the retaining ring 10 to insert the tip of the retaining ring 10 into the pipe 9. Screw the threaded pipe 5 clockwise into the internal thread of the connector 1. The surface of the adapter pipe 5 has threads. Screw the threaded collar 8 counterclockwise into the surface thread of the adapter pipe 5 and tighten it. The surface of the adapter pipe 4 has threads. Screw the nut 12 clockwise into the surface thread of the adapter pipe 4 and tighten it. There is a limit groove on the surface of the connector 1. The first limit plate 6 restricts the movement of the threaded collar 8 in the limit groove, so that the rotation directions of the threaded collar 8 and the threaded pipe 5 are opposite.
[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
