Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, specifically to a repairable leak-proof pipe fitting. Background Technology

[0002] Pipelines are typically made of metal, plastic, or composite materials. Their main function is to transport and distribute various fluids or substances. They are widely used in many fields such as industry, construction, transportation, and energy. However, due to factors such as long-term use, changes in the external environment, and pressure fluctuations, pipelines may leak, leading to fluid loss and safety hazards. Therefore, leak-proof pipe fittings are required.

[0003] There are many different types of leak-proof pipe fittings on the market, but these devices are usually fixed to the pipes and difficult to disassemble. Once a leak or malfunction occurs, operators need to perform complicated manual operations. The entire maintenance process is cumbersome and time-consuming, increasing maintenance costs and downtime losses. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a repairable leak-proof pipe fitting to solve the problem mentioned in the background art that some devices on the market are usually fixed to the pipeline and difficult to disassemble. Once a leak or malfunction occurs, the operator needs to perform complicated manual operations, the whole maintenance process is cumbersome and time-consuming, and the maintenance cost and downtime loss are increased.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A repairable leak-proof pipe fitting includes a limiting mechanism, an auxiliary mechanism, and a protective mechanism. The limiting mechanism is located on the surface of the protective mechanism, and the auxiliary mechanism is located inside the limiting mechanism. The limiting mechanism includes a limiting ring, with a limiting post slidably connected inside the limiting ring. A circular plate is rotatably connected to the front end of the limiting post, and a fixing post is fixedly connected to the front end of the circular plate. A spring is sleeved on the surface of the fixing post, and a limiting block is fixedly connected to the surface of the limiting post. A groove is formed on the inner wall of the limiting ring, and a limiting groove is formed at the rear end of the limiting ring. A pull ring is fixedly connected to the rear end of the limiting post, and a rotating ring is rotatably connected to the front end of the limiting ring. A sliding groove is formed inside the rotating ring, and a limiting plate is slidably connected inside the sliding groove.

[0009] Through the above technical solution, the extension and retraction of the spring ensures that the limiting block can slide correctly into the limiting groove during operation, thus ensuring the overall stability of the device during disassembly.

[0010] As a further improvement to the above solution, the number of limiting blocks is set to two, and the two limiting blocks are symmetrically distributed vertically around the limiting post. The limiting blocks are slidably connected inside the groove. The number of limiting slots is set to two, and the two limiting slots are symmetrically distributed horizontally around the limiting post.

[0011] The above technical solution, with its symmetrically arranged limiting blocks and grooves, can further improve the stability of the disassembly process, thereby enhancing its practical effect.

[0012] As a further improvement to the above solution, the auxiliary mechanism includes a circular groove one, the inside of which is threaded with a bolt, and the inside of the limiting plate is provided with a circular groove two, through which the bolt passes.

[0013] Through the above technical solution, the bolts can limit the position of the limiting plate, thereby further ensuring the overall stability of the connecting pipe inside the slide groove and avoiding unnecessary loosening.

[0014] As a further improvement to the above solution, the protective mechanism includes a main tube, a connecting tube installed at the front end of the main tube, a sealing ring fixedly connected to the surface of the rear end of the connecting tube, a limiting plate fixedly connected to the surface of the connecting tube, and a rotating ring rotatably connected to the surface of the main tube.

[0015] Through the above technical solution, the sealing ring ensures the overall airtightness of the device and prevents gas or liquid leakage.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By setting a limiting mechanism, the operator can move the limiting post by pulling the pull ring, causing the limiting post and the circular plate to move together. The fixed post is also moved, thus removing the limiting effect of the fixed post on the rotating ring. The operator can then rotate the pull ring to rotate the limiting block to the limiting groove position. At this point, the pull ring is released, and the limiting block is pushed into the limiting groove by the restoring force of the spring, completing the fixation of the limiting post. Afterward, the operator can rotate the rotating ring to disengage the limiting plate from the limiting groove, thereby allowing the main tube and the connecting tube to be separated. This allows the operator to easily disassemble and inspect the tube while ensuring stability during installation.

[0018] 2. Through the cooperation of the auxiliary mechanism and the protective mechanism, the bolt is loosened and removed from the circular groove, so that the limiting plate loses its original fixation. After the limiting plate is released, the main tube and the connecting tube can be separated by rotating the rotating ring. The sealing ring ensures the airtightness of the whole device during installation, preventing gas or liquid leakage and further improving the actual effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0027] A repairable leak-proof pipe fitting includes a limiting mechanism 1, an auxiliary mechanism 2, and a protective mechanism 3. The limiting mechanism 1 is located on the surface of the protective mechanism 3, and the auxiliary mechanism 2 is located inside the limiting mechanism 1. The limiting mechanism 1 includes a limiting ring 101, with a limiting post 102 slidably connected inside the limiting ring 101. A circular plate 112 is rotatably connected to the front end of the limiting post 102, and a fixing post 103 is fixedly connected to the front end of the circular plate 112. A spring 104 is sleeved on the surface of the fixing post 103, and a limiting block 10 is fixedly connected to the surface of the limiting post 102. 5. The inner wall of the limiting ring 101 is provided with a groove 106, and the rear end of the limiting ring 101 is provided with a limiting groove 107. The rear end of the limiting post 102 is fixedly connected with a pull ring 108, and the front end of the limiting ring 101 is rotatably connected with a rotating ring 109. The interior of the rotating ring 109 is provided with a sliding groove 110, and the interior of the sliding groove 110 is slidably connected with a limiting plate 111. The extension and retraction of the spring 104 ensures that the limiting block 105 can correctly slide into the interior of the limiting groove 107 during operation, thus ensuring the overall stability of the device during disassembly.

[0028] The number of limiting blocks 105 is set to two, and the two limiting blocks 105 are symmetrically distributed vertically around the limiting post 102. The limiting blocks 105 are slidably connected inside the groove 106. The number of limiting grooves 107 is set to two, and the two limiting grooves 107 are symmetrically distributed horizontally around the limiting post 102.

[0029] The auxiliary mechanism 2 includes a circular groove 201, with a bolt 202 threaded inside the circular groove 201. A circular groove 203 is opened inside the limiting plate 111, and the bolt 202 passes through the circular groove 203. The bolt 202 can limit the limiting plate 111, thereby further ensuring the overall stability of the connecting pipe 302 inside the slide groove 110 and avoiding unnecessary loosening.

[0030] The protective mechanism 3 includes a main tube 301, a connecting tube 302 installed at the front end of the main tube 301, a sealing ring 303 fixedly connected to the surface of the rear end of the connecting tube 302, a limiting plate 111 fixedly connected to the surface of the connecting tube 302, and a rotating ring 109 rotatably connected to the surface of the main tube 301. The sealing ring 303 ensures the overall airtightness of the device and prevents gas or liquid leakage.

[0031] Working principle: When the device needs maintenance, the operator first loosens bolt 202 to remove it from the circular groove 201. At this point, the limiting plate 111 loses the constraint of bolt 202. Then, the operator pulls the pull ring 108 outwards to move the limiting post 102. The limiting post 102 then moves the circular plate 112, which in turn moves the fixing post 103. Simultaneously, spring 1... 04 will elongate under tensile force. When the limiting block 105 slides out of the groove 106, the operator rotates the limiting post 102 90° using the pull ring 108. At this time, the limiting block 105 will rotate to the position of the limiting groove 107. Then, the operator releases the pull ring 108, and the spring 104 will cause the limiting post 102 to retract, thereby allowing the limiting block 105 to slide into the limiting groove 107, thus limiting the limiting post 102. At this time, the fixing post 103 does not interfere with the rotation. Ring 109 provides a limiting position. The operator can rotate ring 109 to disengage the limiting plate 111 from the sliding groove 110, thereby separating the main tube 301 and the sealing ring 303. The sealing ring 303 ensures the overall airtightness of the device during installation. After the operator completes the maintenance, the main tube 301 and the connecting tube 302 are reassembled. Then, the operator rotates ring 109 in the opposite direction to limit the connecting tube 302. Finally, the operator pulls ring 108 again to release the limiting block 10. 5. After disengaging from the limiting groove 107, rotate in the opposite direction to allow the limiting block 105 to slide again inside the groove 106. The spring 104 can drive the limiting post 102 to retract, so that the fixed post 103 can limit the rotating ring 109 again, further ensuring the stability of the device. Finally, the operator will tighten the bolt 202 into the rotating ring 109 to limit the limiting plate 111 and prevent the limiting plate 111 from shaking inside the slide groove 110.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
