[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-5 A spiral telescopic connecting pipe that is easy to assemble and disassemble includes a connecting pipe 1 and a fixing pipe 3. A rubber ring 2 is provided on the upper part of the connecting pipe 1 to prevent leakage. The rubber ring 2 is wrapped around the outer wall of the connecting pipe 1. The connecting pipe 1 is also provided with a driving mechanism to drive the rubber ring 2 to retract, which is used to wrap and seal the connection to prevent leakage due to poor sealing at the connection, which could lead to mechanical failure.

[0027] The driving mechanism includes a first slide groove 9 and a first slider 8. The first slide groove 9 is formed on the outer wall of the connecting pipe 1. The first slider 8 slides on the first slide groove 9 and is fixed to the end of the rubber ring 2 by a clamping sleeve. The first slide groove 9 is also provided with a plurality of first grooves. This configuration provides traction force to the rubber ring 2. The rubber ring 2 is contracted and fixed by sliding the first slider 8 on the first slide groove 9, thereby improving the sealing effect at the connection.

[0028] The driving mechanism also includes a limiting rod 7. A first movable hole is provided on the first slider 8, and the limiting rod 7 is set in the first movable hole. The limiting rod 7 abuts against the bottom of the first groove through the first movable hole. This arrangement can limit the first slider 8 and improve the fixing effect of the connecting pipe 1.

[0029] The fixed tube 3 is provided with multiple clamping rods 11 for clamping the connecting tube 1. The fixed tube 3 is also provided with a rotating mechanism for driving the clamping rods 11 to move vertically, which is used to facilitate the operator to install and disassemble the connecting tube 1. The operator drives the clamping rods 11 to move vertically through the rotating mechanism, so that the clamping rods 11 clamp the connecting tube 1, reducing the operator's installation and disassembly time.

[0030] The rotating mechanism includes a fixed ring 4 and a sliding ring 5. The fixed ring 4 is coaxially fixed to the outer wall of the fixed tube 3 by a clamping sleeve, and the sliding ring 5 is coaxially arranged on the fixed ring 4. This arrangement provides support for the clamping rod 11.

[0031] The rotating mechanism also includes a second slide groove 17 and multiple second sliders 16. The second slide groove 17 is formed on the fixed ring 4 and is circular. The second sliders 16 are symmetrically fixed on the outer wall of the sliding ring 5 by bolt assemblies, and the second sliders 16 rotate and slide within the second slide groove 17. The sliding ring 5 rotates within the second slide groove 17 through the multiple second sliders 16. This configuration provides power transmission to the clamping rod 11, which slides on the fixed ring 4 through the sliding ring 5, reducing the time required for operators to install and disassemble the connecting pipe 1 and preventing the overall installation efficiency from being affected by excessive installation time.

[0032] The fixed tube 3 is also provided with a support mechanism to support the vertical movement of the clamping rod 11. This mechanism supports the vertical movement of the clamping rod 11, prevents the clamping rod 11 from resetting after vertical movement, which would lead to unstable clamping effect, mechanical failure, and ensure the fixing effect of the clamping rod 11.

[0033] The support mechanism has multiple protrusions 10 and a support ring 14. The protrusions 10 are fixedly connected to the inner wall of the sliding ring 5 by bolt assembly, and the support ring 14 is coaxially fixed to the outer wall of the fixed tube 3 by clamping sleeve. This configuration provides support force for the clamping rod 11.

[0034] The support mechanism also includes a connecting ring 15 and multiple support blocks 13. The connecting ring 15 is coaxially fixed to the outer wall of the fixed tube 3 by a clamping sleeve. The multiple support blocks 13 are circumferentially fixed to the inner wall of the support ring 14 by a bolt assembly, and the multiple support blocks 13 are fixedly connected to the connecting ring 15 by the bolt assembly. This arrangement allows the support ring 14 to be fixedly connected to the connecting ring 15 through the support blocks 13. This cooperation prevents the clamping rod 11 from shifting its position when it moves vertically in the third and fourth movable holes, which would cause the clamping effect to be unstable.

[0035] The support mechanism also includes multiple springs 12 and limiting plates 6. The clamping rod 11 is provided with hooks. One end of the spring 12 is set on the side wall of the clamping rod 11 through the hook. The inner side wall of the support ring 14 is provided with hooks. The other end of the spring 12 is connected to the support ring 14 through the hooks. The springs 12 and clamping rods 11 are arranged in a one-to-one correspondence. Multiple second movable holes are opened on the fixed ring 4. The limiting plate 6 is set in the second movable holes. Multiple second grooves are opened on the support ring 14. The limiting plate 6 abuts against the bottom of the second groove through the second movable holes. The limiting plate 6 limits the sliding ring 5 to prevent the sliding ring 5 from rotating excessively, which would cause the clamping rod 11 to be unable to clamp the connecting pipe 1 and prevent mechanical failure.

[0036] The end of the protrusion 10 is provided with an inclined surface, and the end of the clamping rod 11 is provided with an inclined surface that matches the protrusion 10. The connecting ring 15 is provided with a fourth movable hole. The sliding ring 5 drives the protrusion 10 to rotate. The protrusion 10 is connected to the clamping rod 11. The protrusion 10 drives the clamping rod 11 to move vertically. The clamping rod 11 clamps the connecting tube 1 by moving vertically through the third movable hole and the fourth movable hole. This arrangement allows the clamping rod 11 to move vertically along the inclined surface of the protrusion 10.

[0037] The support ring 14 has multiple third movable holes in a circular shape, and the clamping rod 11 is set in the third movable hole. The clamping rod 11 is L-shaped.

[0038] The bolt assembly described above is prior art. The bolt assembly includes a bolt and a threaded hole for threading two components together.

[0039] The functional principle of this utility model can be explained through the following operation methods:

[0040] During use, the operator places the connecting pipe 1 into the fixing pipe 3. The first slider 8 drives the rubber ring 2 to slide on the first groove 9. The limiting rod 7 abuts against the bottom of the first groove through the first movable hole. The limiting rod 7 limits the first slider 8. The rubber ring 2 is wrapped around the outer wall of the connecting pipe 1.

[0041] The operator rotates the sliding ring 5, which rotates on the second slide groove 17 via the second slider 16. The sliding ring 5 drives the protrusion 10 to rotate, and the inclined surface of the protrusion 10 is in contact with the inclined surface of the end of the clamping rod 11. The clamping rod 11 moves vertically within the third and fourth movable holes. The clamping rod 11 abuts against the connecting pipe 1 through the third and fourth movable holes. The limiting plate 6 abuts against the bottom of the second groove through the second movable hole to prevent the sliding ring 5 from continuing to slide. The limiting plate 6 limits the sliding ring 5.

[0042] When disassembly is required, the limiting plate 6 is pulled out, the sliding ring 5 is released from its limit, the spring 12 stretches the clamping rod 11, the clamping rod 11 moves vertically between the third and fourth movable holes, and the operator pulls out the connecting pipe 1.

[0043] 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.
