At the same time, the setting of the first protective sleeve and the second protective sleeve can provide side sealing protection for the side protective pipe".

[0004] However, in actual use, this technical solution requires several threaded rods and matching fastening sealing plates to connect the pipes. It also requires the use of auxiliary tools to achieve the connection between the pipes. In addition, there are many accessories and parts, which leads to many operation steps and makes the pipe connection installation more complicated, thus reducing the efficiency of pipe connection installation.

[0005] Therefore, in order to solve the above problems, this utility model proposes a high-efficiency docking pipe fitting. Utility Model Content

[0006] The main objective of this invention is to provide a high-efficiency docking pipe fitting that can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A high-efficiency docking pipe fitting includes two pipe bodies for docking. The two pipe bodies are fixedly connected together by a docking installation mechanism, which includes a connecting pipe, a sealing ring, an outer rotating ring, a movable block, an L-shaped pull plate, and a clamping plate. The outer walls of the socket pipes at both ends of the connecting pipe are fitted with sealing rings, and the two outer rotating rings are movably connected to the outer walls of the connecting pipe through internal threads on their inner walls. A set of symmetrical movable blocks are also movably connected to the outer walls of the connecting pipes at both ends through sliding blocks, and the outer rotating rings are movably connected to the movable blocks through T-shaped rings on their outer walls. The L-shaped pull plate is movably connected to the movable blocks through rotating rods at both ends of the connecting blocks on the inner walls, and the clamping plate is fixedly connected to the inner wall of the vertical part of the L-shaped pull plate.

[0009] Preferably, a fixing ring is fixedly installed on the outer wall of the connecting end of the pipe body, and a set of symmetrical positioning notches are opened on the outer wall of the fixing ring. A retaining notch is also opened on the side wall of the fixing ring below the positioning notch.

[0010] Preferably, socket tubes are fixedly installed at both ends of the connecting tube, and a sealing ring is fitted on the outer wall of the socket tube. A set of symmetrical external threads is provided on the outer wall of the connecting tube, and a set of symmetrical sliding grooves are provided on both sides of the outer wall of the connecting tube.

[0011] Preferably, the inner wall of the outer spiral ring is provided with an internal thread for external thread connection, and a T-shaped ring is fixedly installed on the outer wall of the outer spiral ring.

[0012] Preferably, a T-shaped groove is provided on the inner side wall of the movable block, and a T-shaped ring is movably installed in the T-shaped groove. A sliding block is fixedly installed on the bottom surface of the movable block, and the sliding block is movably installed in the sliding groove. A set of symmetrical fixing blocks is fixedly installed on the outer side wall of the movable block, and a rotation hole is provided on the front end wall of the fixing block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the docking installation mechanism involves fitting sealing rings onto the outer walls of the socket pipes at both ends of the connecting pipe during the docking installation. After inserting the socket pipes into the pipes on both sides, the L-shaped pull plate is flipped so that its lateral part engages with the positioning notch. The outer rotating ring on the outer wall of the connecting pipe is then rotated, causing the T-shaped ring to drive the movable block to slide on the outer wall of the connecting pipe as it rotates along the outer thread. This continues until the locking plate enters the locking slot and the outer rotating ring can no longer rotate, thus achieving the purpose of quickly docking and fixing the two pipe bodies together. The sealing rings, in conjunction with the connection, ensure the sealing of the pipe bodies after docking, preventing leakage at the connection point between the pipe bodies and the connecting pipe. This makes the installation steps and operations simple and convenient, and improves the efficiency of docking installation. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 - Figure 5As shown, a high-efficiency docking pipe fitting includes two pipe bodies 1 for docking. The two pipe bodies 1 are fixedly connected together by a docking installation mechanism 2. The docking installation mechanism 2 includes a docking pipe 6, a sealing ring 8, an outer rotating ring 11, a movable block 14, an L-shaped pull plate 19, and a clamping plate 20. The outer walls of the socket pipes 7 at both ends of the docking pipe 6 are fitted with sealing rings 8. The two outer rotating rings 11 are movably connected to the outer walls of the docking pipe 6 through internal threads 12 on their inner walls. At both ends of the outer walls of the docking pipe 6, a set of symmetrical movable blocks 14 are movably connected through sliding blocks 16. The outer rotating rings 11 are movably connected to the movable blocks 14 through T-shaped rings 13 on their outer walls. The L-shaped pull plate 19 is movably connected to the movable blocks 14 through rotating rods 22 at both ends of the inner wall connecting block 21. The clamping plate 20 is fixedly connected to the inner wall of the vertical part of the L-shaped pull plate 19.

[0024] like Figure 2 As shown, a fixing ring 3 is fixedly installed on the outer wall of the connecting end of the pipe body 1. The fixing ring 3 set at the connecting end of the pipe body 1 is used to cooperate with the docking installation mechanism 2 for docking installation. A set of symmetrical positioning notches 4 are opened on the outer wall of the fixing ring 3. The positioning notches 4 are used to cooperate with the L-shaped pull plate 19 to position the connecting pipe 6 between the pipe bodies 1. The side wall of the fixing ring 3 and below the positioning notches 4 are also provided with a bayonet 5. The bayonet 5 is used to cooperate with the clamping plate 20 to connect and fix the pipe body 1.

[0025] like Figure 3 As shown, socket tubes 7 are fixedly installed at both ends of the connector 6. By inserting the socket tubes 7 into the pipe body 1, the pipe body 1 can be connected together through the connector 6. A sealing ring 8 is fitted on the outer wall of the socket tube 7. The sealing ring 8 can ensure the sealing line of the pipe body 1 after the connection is installed. A set of symmetrical external threads 9 are opened on the outer wall of the connector 6. The external threads 9 are used to cooperate with the internal threads 12. A set of symmetrical sliding grooves 10 are also opened on both sides of the outer wall of the connector 6. The sliding grooves 10 are used to cooperate with the sliding block 16 to achieve sliding operation.

[0026] like Figure 4 and Figure 5 As shown, the inner wall of the outer rotating ring 11 is provided with an internal thread 12 connected by an external thread 9. When the outer rotating ring 11 is rotated, the outer rotating ring 11 can rotate and move along the external thread 9 through the internal thread 12 on the outer wall of the connecting pipe 6 to provide tension to the movable block 14. A T-shaped ring 13 is fixedly installed on the outer wall of the outer rotating ring 11. The outer rotating ring 11 can drive the movable block 14 to move through the T-shaped ring 13.

[0027] like Figure 4 and Figure 5As shown, a T-shaped groove 15 is provided on the inner side wall of the movable block 14, and a T-shaped ring 13 is movably installed in the T-shaped groove 15. A sliding block 16 is fixedly installed on the bottom surface of the movable block 14, and the sliding block 16 is movably installed in the slide groove 10. A set of symmetrical fixed blocks 17 is fixedly installed on the outer side wall of the movable block 14, and a rotating hole 18 is provided on the front end wall of the fixed block 17. The rotating hole 18 on the fixed block 17 is used to cooperate with the rotating rod 22 to realize the rotation operation. Since the T-shaped ring 13 is located in the T-shaped groove 15, the movable block 14 will move inward under the drive of the outer rotating ring 11, and the sliding block 16 slides in the slide groove 10 to guide the movement of the movable block 14.

[0028] like Figure 4 and Figure 5 As shown, a connecting block 21 is fixedly installed on the inner wall of the L-shaped pull plate 19, and a rotating rod 22 is fixedly installed at the front and rear ends of the connecting block 21 respectively. The rotating rod 22 is movably installed in the rotating hole 18. A clamping plate 20 corresponding to the bayonet 5 is fixedly installed on the inner wall of the vertical part of the L-shaped pull plate 19. After the rotating rods 22 at both ends of the connecting block 21 rotate in the fixed block 17, the horizontal part of the L-shaped pull plate 19 can be driven to rotate and then be locked into the positioning notch 4. After the L-shaped pull plate 19 moves inward under the action of the movable block 14, the vertical part of the L-shaped pull plate 19 will move along the positioning notch 4 until the clamping plate 20 enters the bayonet 5, and the end wall of the pipe body 1 is squeezed to seal the sealing ring 8 to ensure the sealing after connection. After the outer rotating ring 11 can no longer rotate, the two pipe bodies 1 can be quickly connected and fixed together.

[0029] The specific operation for connecting and installing the two rods using the docking installation mechanism 2 is as follows:

[0030] Sealing rings 8 are fitted onto the outer walls of the socket pipes 7 at both ends of the connector 6. Then, the socket pipes 7 at both ends of the connector 6 are inserted into the corresponding connecting ends of the two pipe bodies 1. After ensuring that the positioning notch 4 on the outer wall of the fixing ring 3 is at the same horizontal position as the L-shaped pull plate 19 on the outside of the connector 6, the L-shaped pull plate 19 is flipped inward. The rotating rods 22 at both ends of the connecting block 21 on the inner wall of the L-shaped pull plate 19 will be opened on the front wall of the symmetrical fixing block 17 installed on the outer wall of the movable block 14. The L-shaped pull plate 19 is rotated within the rotating hole 18 until it is engaged in the positioning notch 4. Then, the outer rotating ring 11 located on the outer wall of the connecting pipe 6 is rotated, causing the outer rotating ring 11 to rotate along the thread 9 on the outer wall of the connecting pipe 6 via the internal thread 12 on the inner wall and move inward. At this time, the outer rotating ring 11 will drive the T-shaped ring 13 installed on the outer wall to rotate within the T-shaped groove 15 opened on the inner wall of the movable block 14, thereby driving the movable block 14 to move inward on the outer wall of the connecting pipe 6. When the sliding block 16 installed on the bottom surface of the movable block 14 slides in the corresponding groove 10 opened on the outer wall of the connecting pipe 6, the movable block 14 will drive the L-shaped pull plate 19 to move inward in sync. The horizontal part of the L-shaped pull plate 19 will move along the positioning notch 4 until the clamping plate 20 installed on the inner wall of the vertical part of the L-shaped pull plate 19 enters the clamping slot 5 opened on the side wall of the fixing ring 3. By continuously pulling the fixing ring 3 inward through the clamping plate 20 and the L-shaped pull plate 19, the pipe body 1 and the connecting pipe 6 can be tightened and fixed together. The sealing ring 8 between the pipe body 1 and the connecting pipe 6 is squeezed to ensure the sealing of the connection between the pipe body 1 and the connecting pipe 6. After the internal thread 12 can no longer be rotated, the two pipe bodies 1 can be connected and fixed together. The connecting pipe 6 can make the medium flow through the pipe body 1 during transportation. Thus, the installation steps and operations are simple and convenient when connecting the pipe bodies 1, and the efficiency of the connection installation is improved.

[0031] The above description is merely 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, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
