Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and more specifically, to a non-detachable pipe connector. Background Technology

[0002] In existing technologies, the use of pipe connectors generally relies on bolt fastening. Specifically, such connectors typically consist of two mating pipe interfaces, which are fastened together by bolts and nuts. During operation, workers need to use tools such as wrenches to tighten the bolts to ensure the sealing and stability between the pipe interfaces. This connection method can indeed provide reliable connection results in the initial use and is suitable for various working conditions.

[0003] However, over time, bolted pipe connectors will gradually reveal some problems. First, due to environmental factors such as temperature changes, vibration, and corrosion, the bolts may loosen, thus affecting their tightening effect. The combined effect of these factors makes bolted pipe connectors risk falling off after a period of use. Once the connector falls off, it will not only cause leakage in the pipeline system, but may also cause more serious safety accidents, such as equipment damage, media leakage, or even personal injury.

[0005] In view of the problems existing in the prior art, this utility model provides an anti-detachment pipe connector to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment pipe connector, comprising a jacket, which is installed on an external pipeline. A fixing mechanism is provided on the jacket, comprising a threaded rod, a threaded sleeve, an inner sleeve, an insertion rod, an inner rod, a handle, a release mechanism, and a sealing mechanism. The sealing mechanism is installed inside the jacket. The threaded rod and the threaded sleeve respectively abut against both sides of the jacket. The threaded rod is threadedly connected to the threaded sleeve. The inner sleeve is fixedly installed inside the threaded sleeve. The insertion rod is slidably connected to the inner sleeve. An insertion hole is provided inside the threaded rod, and the insertion rod is engaged in the insertion hole. The handle is coaxially mounted on the inner rod, which is connected to the insertion rod. The inner rod is slidably connected to the inner sleeve. The release mechanism is installed inside the inner sleeve.

[0008] The present invention is further configured such that a plurality of elastic pieces are equidistantly arranged on the inner wall of the inner sleeve, and a snap-fit ​​groove is opened on the side wall of the inner rod, with the elastic pieces abutting against the snap-fit ​​groove. The design of the elastic pieces ensures the stability of the snap-fit.

[0009] The present invention is further configured such that a return spring is provided inside the inner sleeve, and the two ends of the plurality of return springs respectively abut against the inner sleeve and the inner rod. The design of the return spring ensures the continuity of disassembly.

[0010] The present invention is further configured such that the unlocking mechanism includes an unlocking sleeve, which is slidably connected to the inner rod and fits against the plurality of elastic sheets. The design of the unlocking mechanism ensures the convenience of unlocking.

[0011] The present invention is further configured such that a plurality of side grooves are provided on the side wall of the internal rod, and a push plate is slidably connected in each side groove. The plurality of push plates are respectively connected to the release sleeve. The design of the side grooves ensures the sliding of the push plates.

[0012] The present invention is further configured such that the upper end of the plurality of push plates is provided with a push sleeve, the push sleeve is slidably connected to the inner rod, and the handle abuts against the push sleeve.

[0013] The present invention is further configured such that the sealing mechanism includes a rubber sleeve and a shrink sleeve, the rubber sleeve is installed inside the jacket, and the external pipeline is clamped inside the rubber sleeve and the shrink sleeve.

[0014] The present invention is further configured such that two shrink sleeves are symmetrically arranged, and the two shrink sleeves are respectively installed on both sides of the jacket.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an anti-detachment pipe connector, which has the following advantages:

[0017] 1. The fixing mechanism achieves a stable installation of the clamp on the external pipeline through the cooperation of the threaded rod and the threaded sleeve. The threaded connection between the threaded rod and the threaded sleeve allows the two sides of the clamp to come close together by rotating the threaded rod, thereby effectively clamping the pipeline. The inner sleeve is fixed inside the threaded sleeve, and the insertion rod slides inside the inner sleeve and engages with the threaded rod through the insertion hole, further enhancing the stability of the connection. The handle is coaxially installed on the inner rod, which is connected to the insertion rod, ensuring simple operation and direct force transmission. This multi-fixing design not only improves the reliability of the connection but also greatly reduces the risk of loosening caused by vibration or external force.

[0018] 2. The unlocking mechanism achieves rapid unlocking of the connection through the interaction of the elastic plate on the inner wall of the inner sleeve and the snap-fit ​​groove on the side wall of the inner rod. The unlocking sleeve slides onto the inner rod and fits against the elastic plate. Through the linkage of the push plate and the push sleeve, when the handle is pressed, the unlocking sleeve pushes the elastic plate downward, releasing the engagement between the elastic plate and the snap-fit ​​groove. This design makes the unlocking process simple and effortless, avoiding the tedious operation of repeated rotation required by traditional bolt connections. In addition, the return spring ensures that the inner rod can automatically reset after unlocking, further improving the convenience and safety of operation.

[0019] 3. The sealing mechanism, through a dual-seal design of rubber sleeve and shrink sleeve, ensures highly efficient sealing of the pipeline connection. The rubber sleeve is installed inside the jacket, and the external pipeline is clamped between the rubber sleeve and the shrink sleeve. The shrink sleeve is symmetrically installed on both sides of the jacket, providing a second layer of sealing protection. This dual-seal structure not only effectively prevents media leakage but also enhances the pressure resistance of the connection. The fit of the rubber sleeve and the tightening effect of the shrink sleeve ensure that the sealing effect remains stable under various operating conditions. In summary, the sealing mechanism, through its multi-layer sealing design, significantly improves the sealing performance and reliability of the pipeline connection. Attached Figure Description

[0029] Please see Figure 1-5 A type of anti-detachment pipe connector includes a jacket 1, which is installed on an external pipe. A fixing mechanism is provided on the jacket 1, comprising a threaded rod 2, a threaded sleeve 3, an inner sleeve 4, an insertion rod 5, an inner rod 6, a handle 7, a release mechanism, and a sealing mechanism. The sealing mechanism is installed inside the jacket 1. The threaded rod 2 and the threaded sleeve 3 respectively abut against both sides of the jacket 1. The threaded rod 2 is threadedly connected to the threaded sleeve 3. The inner sleeve 4 is fixedly installed inside the threaded sleeve 3. The insertion rod 5 is slidably connected to the inner sleeve 4. An insertion hole 8 is provided inside the threaded rod 2, and the insertion rod 5 is engaged in the insertion hole 8. The handle 7 is coaxially mounted on the inner rod 6, which is connected to the insertion rod 5 and slidably connected to the inner sleeve 4. The release mechanism is installed inside the inner sleeve 4. Multiple elastic pieces 9 are equidistantly arranged on the inner wall of the inner sleeve 4. A snap-fit ​​groove 10 is provided on the side wall of the inner rod 6. The elastic plate 9 abuts against the snap-fit ​​groove 10. The inner sleeve 4 is provided with a return spring 11. The two ends of the multiple return springs 11 abut against the inner sleeve 4 and the inner rod 6 respectively. The release mechanism includes a release sleeve 12, which is slidably connected to the inner rod 6 and fits against multiple elastic plates 9. Multiple side grooves 13 are provided on the side wall of the inner rod 6. Each side groove 13 is slidably connected to a push plate 101. Multiple push plates 101 are connected to the release sleeve 12 respectively. The upper end of the multiple push plates 101 is provided with a push sleeve 14, which is slidably connected to the inner rod 6. The handle 7 abuts against the push sleeve 14. The sealing mechanism includes a rubber sleeve 15 and a shrink sleeve 16. The rubber sleeve 15 is installed in the jacket 1, and the external pipeline is clamped in the rubber sleeve 15 and the shrink sleeve 16. Two shrink sleeves 16 are symmetrically arranged, and the two shrink sleeves 16 are respectively installed on both sides of the jacket 1.

[0030] In this embodiment, when fixing the external pipeline, the clamp 1 is first inserted into the external pipeline at both ends. Then, the threaded rod 2 and the threaded sleeve 3 are respectively pressed against the two ends of the clamp 1. By rotating the threaded rod 2, the clamps 1 on both sides can be brought closer together, thus sealing the pipeline on both sides. Then, the rubber sleeve 15 is attached to the pipeline on both sides, and the shrink sleeve 16 provides a second layer of sealing, thus ensuring the sealing effect.

[0031] More specifically, after the threaded rod 2 and threaded sleeve 3 are fixed, pressing the handle 7 can drive the insertion rod 5 to slide towards the insertion hole 8, thus locking the insertion rod 5 inside the insertion hole 8, and the inner sleeve 4 and threaded sleeve 3 are in a fixed state, thus ensuring the double fixation of the threaded rod 2 and threaded sleeve 3. When it is necessary to untie, continue to push the handle 7, so that the handle 7 presses against the push plate 101, which drives the release sleeve 12 to slide downward. At the same time, the release sleeve 12 presses against the elastic piece 9, thus untying the connection between the elastic piece 9 and the locking groove 10. At this time, the insertion rod 5 can be pulled out, thereby untying the connection.

[0032] In summary, when using or operating the overall equipment: First, insert the clamp 1 into the external pipelines at both ends. Then, the threaded rod 2 and threaded sleeve 3 press against the ends of the clamp 1. Rotating the threaded rod 2 moves the clamps 1 closer together, thus sealing the pipelines on both sides. The rubber sleeve 15 then fits against the pipelines on both sides, and the shrink sleeve 16 provides a second layer of sealing, ensuring a good seal. After fixing the threaded rod 2 and threaded sleeve 3, pressing the handle 7 moves the insertion rod 5 towards the insertion hole 8, causing it to lock into the hole. The inner sleeve 4 and threaded sleeve 3 remain fixed, ensuring double fixing of the threaded rod 2 and threaded sleeve 3. When disengaging, continue pushing the handle 7, causing it to press against the push plate 101, which in turn moves the release sleeve 12 downwards. Simultaneously, the release sleeve 12 presses against the elastic plate 9, thus disengaging the connection between the elastic plate 9 and the locking groove 10. At this point, the insertion rod 5 can be pulled out, thus disengaging the connection.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
