Description

Technical Field

[0001] This utility model relates to the field of rubber connector technology, specifically a small quick-connect self-sealing rubber connector. Background Technology

[0002] The sealing principle of self-sealing rubber connectors mainly relies on the elastic deformation of rubber materials. When the connector is subjected to pressure, the rubber will deform and fill the tiny gaps between the joint and the pipe or equipment, forming an effective sealing surface. This elastic deformation allows the connector to adapt to different installation conditions and external pressure changes, thereby ensuring the sealing effect.

[0003] In existing technology, connectors are plugged into each other and sealed by rubber and slots. Then, pins are inserted into the corresponding slots and deformed by compression to make the connector connection stable. However, the deformation of the pins in the slots makes them difficult to remove due to the high resistance. If the connector is damaged and needs to be replaced, a lot of time is required for disassembly, which wastes a lot of time and reduces work efficiency.

[0004] Therefore, this utility model provides a small quick-connect self-sealing rubber connector to solve the above problems. Utility Model Content

A fixing ring is fixedly connected to the outer wall of the end of the second connecting head away from the fixing sleeve, and the fixing ring abuts against the movable sleeve.

[0007] As a preferred technical solution of this application, the inner annular array of the movable sleeve and the sliding end of the second connector is provided with a limiting groove, the middle annular array of the outer wall of the second connector is fixedly connected with a second limiting block, the second limiting block is slidably connected with the storage groove, the annular array of the second connector located on the side of the second limiting block away from the fixed sleeve is slidably engaged with a positioning ball, and the middle of the second connector is provided with a connecting groove.

[0008] As a preferred technical solution of this application, a spring is provided on the outer wall of the second connector inside the storage groove, and the spring is fixedly connected to the movable sleeve and the storage groove respectively.

[0009] As a preferred technical solution of this application, the fixed ring has a first slot in an annular array on the side away from the fixed sleeve, and the first sealing ring is fixedly connected to one end of the first connecting tube located inside the second connecting head.

[0010] As a preferred technical solution of this application, a connector is provided at the end of the second connector away from the first connecting tube. The connector includes the first connector. A positioning slot is formed on the outer wall of the first connector near the end of the first connecting tube. A positioning groove is formed in a circular array on the outer side of the positioning slot. The positioning slot and the positioning groove are engaged with the positioning ball.

[0012] (III) Beneficial Effects By setting up a connecting component, the movable sleeve is pushed, and the movable sleeve slides along the trajectory of the second limiting block through the limiting groove. The movable sleeve gradually compresses the spring, at which point the movable sleeve separates from the positioning ball, and the positioning ball loses its compression. The first connector is then inserted into the connecting groove, the positioning slot aligns with the positioning ball, and the positioning groove and positioning slot engage and limit the positioning ball. Subsequently, the movable sleeve is released, and the spring pushes the movable sleeve to compress the positioning ball, causing the positioning ball to engage and fix the first connector. Therefore, quick insertion can be achieved, improving work efficiency. When the first connector enters the connecting groove, the first limiting block engages with the first slot, thereby limiting the first connector and preventing the first connector from rotating and causing a decrease in sealing.

[0015] 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.

[0016] This utility model provides a small quick-connect self-sealing rubber connector, such as Figures 1-5 As shown, the device includes a first connecting pipe 1, one end of which is provided with a connecting assembly. The connecting assembly includes a second connecting head 34, which is fixed to one end of the first connecting pipe 1. A fixing sleeve 31 is fixedly connected to the outer wall of the second connecting head 34 near the end of the first connecting pipe 1. A receiving groove 311 is provided on one side of the fixing sleeve 31. A movable sleeve 32 is slidably connected to the middle of the outer wall of the second connecting head 34, which is slidably connected inside the fixing sleeve 31. A fixing ring 33 is fixedly connected to the outer wall of the end of the second connecting head 34 away from the fixing sleeve 31, and the fixing ring 33 abuts against the movable sleeve 32. Limiting grooves 321 are formed in the inner annular array of the movable sleeve 32 and the sliding end of the second connecting head 34. The second connector 34 has a second limiting block 343 fixedly connected in a ring array in the middle of its outer wall. The second limiting block 343 is slidably connected to the storage groove 311. The second connector 34 has a positioning ball 342 slidably engaged in a ring array on the side of the second limiting block 343 away from the fixed sleeve 31. The second connector 34 has a connecting groove 341 in the middle. The second connector 34 has a spring 344 inside the storage groove 311 on its outer wall. The spring 344 is fixedly connected to the movable sleeve 32 and the storage groove 311 respectively. The fixed ring 33 has a first slot 331 in a ring array on the side away from the fixed sleeve 31. The first sealing ring 11 is fixedly connected to one end of the first connecting tube 1 inside the second connector 34.

[0017] Specifically, the movable sleeve 32 is pushed, and it slides along the trajectory of the second limiting block 343 through the limiting groove 321. The movable sleeve 32 gradually compresses the spring 344. At this time, the movable sleeve 32 separates from the positioning ball 342, and the positioning ball 342 loses its compression. The first connector 21 is inserted into the connecting groove 341, the positioning slot 23 is aligned with the positioning ball 342, and the positioning groove 24 and the positioning slot 23 engage and limit the positioning ball 342. Then the movable sleeve 32 is released, and the spring 344 pushes the movable sleeve 32 to compress the positioning ball 342, so that the positioning ball 342 is pushed by the movable sleeve 32 into the positioning slot 23 and the positioning groove 24. The positioning ball 342 is locked and fixed in position to the first connector 21. Therefore, quick insertion can be achieved, improving work efficiency.

[0018] like Figures 1-3 As shown, a connector is provided at the end of the second connector 34 away from the first connecting pipe 1. The connector includes a first connector 21. A positioning groove 23 is provided on the outer wall of the first connector 21 near the end of the first connecting pipe 1. A positioning groove 24 is provided in an annular array on the outer side of the positioning groove 23. Both the positioning groove 23 and the positioning groove 24 are engaged with the positioning ball 342. A first limiting block 22 is fixedly connected to the first connector 21 in an annular array on the side of the positioning groove 23 away from the first connecting pipe 1. The first limiting block 22 is engaged with the first groove 331. A connecting block 25 is fixedly connected to the middle part of the first connector 21 near the end of the first connecting pipe 1. A second sealing ring 26 is engaged on the outer wall of the first connector 21 on the side of the connecting block 25 away from the first connecting pipe 1. The second sealing ring 26 abuts against the first connector 21.

[0019] Specifically, when the first connector 21 enters the connecting groove 341, the first limiting block 22 engages with the first slot 331, thereby limiting the first connector 21 and preventing the first connector 21 from rotating and causing a decrease in sealing. When the first connector 21 is inserted into the second connector 34, the second sealing ring 26 is tightly attached to the first sealing ring 11 to achieve a seal. The connecting block 25 is inserted into the interior of the first sealing ring 11, and the outer wall of the connecting block 25 is tightly attached to the inner wall of the first connecting pipe 1, thereby further achieving a seal.

[0020] In summary, when the movable sleeve 32 is pushed, it slides along the trajectory of the second limiting block 343 through the limiting groove 321, and the movable sleeve 32 gradually compresses the spring 344. At this time, the movable sleeve 32 separates from the positioning ball 342, and the positioning ball 342 loses its compression. The first connector 21 is inserted into the connecting groove 341, the positioning slot 23 aligns with the positioning ball 342, and the positioning groove 24 and the positioning slot 23 engage and limit the positioning ball 342. Then, the movable sleeve 32 is released, and the spring 344 pushes the movable sleeve 32 to compress the positioning ball 342, so that the positioning ball 342 is pushed by the movable sleeve 32 into the positioning slot 23 and the positioning block 342. The first connector 21 is fixed in the groove 24 and the positioning ball 342 engages with it, thus enabling quick insertion and improving work efficiency. When the first connector 21 enters the connecting groove 341, the first limiting block 22 engages with the first slot 331, thereby limiting the first connector 21 and preventing the first connector 21 from rotating and reducing the sealing performance. When the first connector 21 is inserted into the second connector 34, the second sealing ring 26 is tightly attached to the first sealing ring 11 to achieve a seal. The connecting block 25 is inserted into the inside of the first sealing ring 11, and the outer wall of the connecting block 25 is tightly attached to the inner wall of the first connecting pipe 1, thereby further achieving a seal.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
