Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) lined siphon technology, and in particular to a PTFE lined siphon that can be quickly connected. Background Technology

[0002] Pipe fittings are used to connect pipe ends to extend the pipe. Pipe construction is a crucial part of water conservancy projects, and pipe fittings, as important accessories for connecting pipes, play a role in securing the connection.

[0003] Traditional pipe fittings mostly use flange connections, which use multiple sets of bolts to clamp two flanges together to connect the pipes. The disassembly and installation of multiple sets of bolts leads to low pipe connection efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a PTFE-lined siphon pipe that can be quickly connected, aiming to improve the problem of low pipe connection efficiency caused by traditional bolted and flanged connections.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PTFE-lined siphon tube that can be quickly connected, comprising a tube body, a flange symmetrically fixedly connected to one end of the tube body, a connecting frame fixedly connected to the outside of the tube body, a connecting rod 1 uniformly fixedly connected to one side of the connecting frame, a connecting ring 1 fixedly connected to one side of the connecting rod 1, a connecting block 1 rotatably connected to one side of the connecting ring 1, anti-slip rings symmetrically fixedly connected to the outer wall of the connecting block 1, a screw rod 1 threadedly connected to the inner wall of the connecting block 1, a connecting block 2 fixedly connected to one side of the screw rod 1, the inner walls of both the screw rod 1 and the connecting block 2 being slidably connected to the outer wall of the tube body, a gathering structure fixedly connected to one side of the connecting block 2, and a limiting structure installed on one side of the tube body.

[0006] By adopting the above technical solution, the anti-slip ring is rotated, and the connecting block one rotates in place using the connecting frame, causing the screw one to advance on the pipe body. This pushes the front gathering structure to clamp the flanges on the two pipe sections, achieving a quick connection. When disassembling, the anti-slip ring is rotated in the opposite direction, causing the connecting block two to retract, opening the gathering structure and releasing the clamping of the flanges on the two pipe sections, thus completing the quick disassembly. When a faster pipe replacement is required and the clamping effect is less critical, a limiting structure can be used to clamp the flanges on the two pipe sections, improving the efficiency of flange connection.

[0007] Preferably, the gathering structure includes a limiting ring one, one side of the limiting ring one is fixedly connected to one side of the connecting block two, and the inner wall of the limiting ring one is slidably connected to the outer wall of the tube body.

[0008] Preferably, a limiting block is evenly provided on one side of the limiting ring, and a connecting ring is fixedly connected to one side of the limiting block, with the inner wall of the connecting ring slidingly connected to the outer wall of the tube.

[0009] Preferably, the limiting structure includes a limiting ring two, a limiting rod is symmetrically fixedly connected to the inner wall of the limiting ring two, a limiting block three is fixedly connected to the outer wall of the limiting rod, one side of the limiting block three is installed on one side of the tube body, and a connecting rod two is fixedly connected to the bottom of the limiting block three.

[0010] Preferably, one end of the connecting rod 2 is fixedly connected to the inner wall of the limiting ring 2, the limiting rod is slidably connected to the outside of the limiting block 2, and the top of the limiting block 2 is fixedly connected to the connecting block 4.

[0011] Preferably, a sliding rod is fixedly connected to the top of the connecting block four, the outside of the sliding rod is slidably connected to the inside of the limiting ring two, and a connecting block three is slidably connected to the outer wall of the sliding rod.

[0012] Preferably, one end of the connecting block three is fixedly connected to a connecting rod three, the bottom of the connecting rod three is fixedly connected to the outer wall of the limiting ring two, and the bottom of the connecting block three is fixedly connected to a limiting spring.

[0013] Preferably, one end of the limiting spring is fixedly connected to the outer wall of the limiting ring two, and the internal thread of the connecting block three is connected to the lead screw two, one end of the lead screw two is fixedly connected to the handwheel.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the anti-slip ring, the connecting block one rotates in place using the connecting frame, causing the screw one to advance on the pipe body, pushing the front gathering structure to gather and clamp the flanges on the two pipe sections, thus achieving a quick connection. When disassembling, the anti-slip ring is rotated in the opposite direction, causing the connecting block two to retract, the gathering structure opens, and the clamping of the flanges on the two pipe sections is released, completing the quick disassembly. When a faster pipe replacement is required and the clamping effect is less critical, a limiting structure can be used to clamp the flanges on the two pipe sections, improving the efficiency of flange connection.

[0016] 2. In this utility model, the connecting block 2 pushes the limiting ring 1 forward, causing the limiting block 1 and the connecting ring 2 to slide forward. The flanges on the two pipe sections enter the middle of the limiting block 1 and are blocked by the inclined side of the limiting block 1. The limiting ring 1 continues to move forward, and the limiting block 1 is squeezed by the inner wall of the limiting ring 1. The limiting block 1 retracts inward and enters the interior of the limiting ring 1. The two flanges in the middle of the limiting block 1 are squeezed forward, but are blocked by the protrusion of the limiting block 1, thus completing the clamping of the two flanges. The limiting ring 1 moves backward, the limiting block 1 returns to its original position, the opening formed by the limiting block 1 is restored, and the clamping of the two flanges is released, completing the quick disassembly.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-4An embodiment of this utility model provides: a quick-connectable polytetrafluoroethylene-lined siphon tube, including a tube body 1, a flange 2 symmetrically fixedly connected to one end of the tube body 1, a connecting frame 5 fixedly connected to the outside of the tube body 1, a connecting rod 6 uniformly fixedly connected to one side of the connecting frame 5, a connecting ring 7 fixedly connected to one side of the connecting rod 6, a connecting block 8 rotatably connected to one side of the connecting ring 7, anti-slip rings 9 symmetrically fixedly connected to the outer wall of the connecting block 8, a threaded screw 10 threadedly connected to the inner wall of the connecting block 8, a connecting block 11 fixedly connected to one side of the threaded screw 10, the inner walls of the threaded screw 10 and the connecting block 11 are slidably connected to the outer wall of the tube body 1, a gathering structure is fixedly connected to one side of the connecting block 11, and a limiting structure is installed on one side of the tube body 1.

[0025] Specifically, by rotating the anti-slip ring 9, the connecting bracket 5 is connected to the pipe body 1. The connecting rod 6 and the connecting ring 7 are used to rotate the connecting block 8 in place, causing the threaded rod 10 connected to the internal thread of the connecting block 8 to advance on the pipe body 1. This drives the connecting block 11 to push the front gathering structure to clamp the flanges 2 on the two sections of the pipe body 1, thus achieving a quick connection between the two sections of the PTFE-lined siphon pipe. When disassembling, the anti-slip ring 9 is rotated in the opposite direction, causing the connecting block 8 to drive the threaded rod 10 and the connecting block 11 to retreat. The gathering structure opens, losing its clamping of the flanges 2 on the two sections of the pipe body 1, thus completing the quick disassembly of the two sections of the PTFE-lined siphon pipe. In special cases where a faster replacement of the pipe is required and the clamping effect is less critical, the limiting structure at the other end of the pipe body 1 can be used to clamp the flanges 2 on the two sections of the pipe body 1, improving the problem of low pipe connection efficiency caused by traditional bolted flange connections.

[0026] Reference Figure 2 , Figure 3 The gathering structure includes a limiting ring 3, one side of which is fixedly connected to one side of a connecting block 11, the inner wall of the limiting ring 3 is slidably connected to the outer wall of the tube 1, a limiting block 4 is evenly arranged on one side of the limiting ring 3, a connecting ring 23 is fixedly connected to one side of the limiting block 4, and the inner wall of the connecting ring 23 is slidably connected to the outer wall of the tube 1.

[0027] Specifically, the connecting block 21 pushes the limiting ring 3 forward, contacting the limiting block 4, which in turn causes the limiting block 4 and the connecting ring 23 to slide forward. The flange 2 on the two pipe sections 1 enters the opening formed between the multiple limiting blocks 4, and is blocked by the inclined side of the limiting block 4. The limiting ring 3 continues to move forward, but the limiting block 4 cannot move forward any further and begins to be squeezed by the inner wall of the limiting ring 3. The elastic metal limiting block 4 contracts inward and gradually enters the interior of the limiting ring 3, thus limiting the movement. The two flanges 2 in the middle of block 4 are squeezed and slide forward, but are blocked by the inward protrusion of the limiting block 4. As the limiting ring 3 continues to advance, it gradually clamps the two flanges 2, realizing the rapid installation of the two PTFE-lined siphon pipes. When disassembling, the limiting ring 3 moves backward, and the limiting block 4 is restored by the restoring elastic force. The opening formed by the multiple limiting blocks 4 becomes larger again, and it is released from the clamping of the flanges 2 on the two pipe sections 1, completing the rapid disassembly of the two PTFE-lined siphon pipes.

[0028] Reference Figure 1 , Figure 4 The limiting structure includes a limiting ring 13, with limiting rods 20 symmetrically fixedly connected to the inner wall of the limiting ring 13. A limiting block 24 is fixedly connected to the outer wall of the limiting rods 20. One side of the limiting block 24 is installed on one side of the pipe body 1. A connecting rod 12 is fixedly connected to the bottom of the limiting block 24. One end of the connecting rod 12 is fixedly connected to the inner wall of the limiting ring 13. A limiting block 14 is slidably connected to the outside of the limiting rods 20. A connecting block 22 is fixedly connected to the top of the limiting block 14. The top of the connecting block 22 is fixedly connected to... There is a slide rod 15, which is slidably connected to the inside of the second limiting ring 13. The outer wall of the slide rod 15 is slidably connected to the third connecting block 17. One end of the third connecting block 17 is fixedly connected to the third connecting rod 21. The bottom of the third connecting rod 21 is fixedly connected to the outer wall of the second limiting ring 13. The bottom of the third connecting block 17 is fixedly connected to the limiting spring 16. One end of the limiting spring 16 is fixedly connected to the outer wall of the second limiting ring 13. The inside of the third connecting block 17 is threadedly connected to the second lead screw 18. One end of the second lead screw 18 is fixedly connected to the handwheel 19.

[0029] Specifically, by moving the slide bar 15, the limiting blocks 14 and 24 are moved to the outside of the flanges 2 on the two pipe sections 1. Pressing the slide bar 15 compresses the limiting spring 16, which pushes the limiting block 14 downward through the connecting block 22, squeezing the flanges 2 on the two pipe sections 1. The arc grooves of the limiting blocks 14 and 24 push the flanges 2 downward, while simultaneously causing the two flanges 2 to converge and clamp towards the middle. Turning the handwheel 19 causes the screw 18 to move towards the connecting block. The sliding block 15 is engaged within the three-section 17, enabling the rapid installation of the two PTFE-lined siphon tubes. During disassembly, the handwheel 19 is turned, causing the lead screw 18 to move outward from the connecting block 17, disengaging from the sliding block 15. The restoring force of the limiting spring 16 causes the sliding block 15, connecting block 22, and limiting block 24 to slide upward. The limiting blocks 24 and 34 disengage from the two flanges 2, completing the rapid disassembly of the two PTFE-lined siphon tubes.

[0030] Working principle: During use, rotating the anti-slip ring 9 causes the connecting block 8 to rotate in place using the connecting bracket 5, which in turn causes the screw 10 to advance on the pipe body 1, driving the limiting ring 3 forward, which in turn drives the limiting block 4 and the connecting ring 23 forward. The flanges 2 on the two pipe sections 1 enter the opening formed between the multiple limiting blocks 4 and are blocked by the inclined side of the limiting block 4. The limiting ring 3 continues to move forward, and the limiting block 4 is squeezed inward by the inner wall of the limiting ring 3, entering the interior of the limiting ring 3. The two flanges 2 in the middle of the limiting block 4 are squeezed forward and blocked by the protrusion of the limiting block 4, clamping the two flanges 2. When disassembling, the limiting ring 3 moves backward, and the limiting block 4 is restored by the restoring elastic force to the opening formed by the multiple limiting blocks 4. When the new pipe is larger and no longer clamped to flange 2, and when a faster replacement of the pipe is required and the clamping effect is less critical, the limiting block 2 14 and the limiting block 3 24 can be moved to the outside of flange 2 on the two pipe sections 1. Pressing the sliding rod 15 pushes the limiting block 2 14 downward, squeezing the flange 2 on the two pipe sections 1. The arc grooves of the limiting block 2 14 and the limiting block 3 24 push the flange 2 downward, while also causing the two flanges 2 to converge and clamp towards the middle. Turning the handwheel 19 engages the sliding rod 15. When disassembling, turning the handwheel 19 causes the sliding rod 15 to lose engagement. The limiting spring 16 drives the sliding rod 15, the connecting block 4 22 and the limiting block 2 14 to slide upward, and the limiting block 2 14 and the limiting block 3 24 disengage from the two flanges 2.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
