Description

Technical Field

[0001] This utility model relates to the field of flexible connector technology, and in particular to a reusable all-copper flexible connector. Background Technology

[0002] In the field of pipeline connections, especially in situations requiring frequent disassembly, length adjustment, or a certain degree of mobility compensation (such as plumbing systems, pneumatic / hydraulic pipelines, laboratory equipment, industrial machinery, etc.), unions play a crucial role, such as the non-destructive union proposed in publication number CN201561226U.

[0003] However, in actual installation, there are often unavoidable errors in the actual installation positions of the pipe fittings. The existing union pipes have fixed lengths and extremely strict requirements on the spacing between the pipe fitting ports. When the spacing is greater than or less than the joint length, the joint or pipe fitting needs to be replaced. The installation process is time-consuming and labor-intensive, often requiring repeated adjustments, pipe cutting, or rework, which increases costs.

[0004] To address this issue, this utility model proposes a reusable all-copper connector. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose an all-copper reusable live pipe joint to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, one embodiment of the present invention provides a reusable all-copper connector, comprising: a main body having a first connecting end thereon; a telescopic tube slidably disposed within the main body having a second connecting end thereon; and a locking mechanism for locking the telescopic tube to the main body.

[0008] Preferably, in any of the above embodiments, a limiting plate is fixedly provided inside the main tube, a limiting block is fixedly provided on the limiting plate, and a first annular groove is formed inside the main tube.

[0009] Preferably, as described in any of the above schemes, the main tube body has a plurality of hemispherical grooves.

[0010] Preferably, in any of the above embodiments, a collar is fixedly provided on the telescopic tube, a guide groove is provided on the collar, the guide groove is in sliding fit with the limiting block, and a slot hole corresponding to the hemispherical groove is provided on the collar.

[0011] Preferably, as described in any of the above schemes, the telescopic tube has a second annular groove.

[0012] Preferably, any of the above solutions also includes a sealing ring, one end of which is embedded in the second annular groove, and the other end of which remains in contact with the inner wall of the first annular groove.

[0013] Preferably, in any of the above embodiments, the locking mechanism includes: a steel ball disposed in the slot for engaging with the hemispherical groove; and a return spring disposed in the slot, one end of which is fixedly connected to the inner wall of the slot, and the other end of which is fixedly connected to the steel ball.

[0014] Preferably, both the main tube and the telescopic tube are made of copper, according to any of the above embodiments.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0016] The telescopic tube can slide freely along the axial direction within the main pipe. The sliding range is determined by the effective stroke defined by the limiting plate and the collar. When there is an installation error (too long or too short) in the length direction between two pipe fittings to be connected (connected to the first and second connection ends respectively), the installer does not need to cut the pipe, add a short section or forcibly bend the pipe. They can simply pull or push the telescopic tube to steplessly adjust the overall length of the joint and accurately match the actual distance between the pipe fittings.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] like Figures 1 to 6 As shown, a reusable all-copper connector includes a main body 1, a telescopic tube 2, a locking mechanism 3, and a sealing ring 4.

[0027] Furthermore, the main body 1 is provided with a first connecting end 11, which is an internal thread interface;

[0028] A limiting plate 12 is fixedly provided inside the main body 1, and a limiting block 13 is fixed on the limiting plate 12. A first annular groove is opened inside the main body 1.

[0029] The main body 1 has several hemispherical grooves inside;

[0030] The main body 1 is made of copper.

[0031] Furthermore, the telescopic tube 2 is slidably disposed inside the main tube body 1, and the telescopic tube 2 is provided with a second connecting end 21, which is an external threaded interface.

[0032] A collar 22 is fixedly provided on the telescopic tube 2. A guide groove is provided on the collar 22. The guide groove is in sliding fit with the limiting block 13. A slot hole corresponding to the hemispherical groove is provided on the collar 22. There are at least two slot holes, which are symmetrically distributed about the axis of the telescopic tube 2.

[0033] The telescopic tube 2 is provided with a second annular groove;

[0034] The telescopic tube 2 is made of copper.

[0035] The sliding fit between the guide groove and the limiting block 13 is used to limit the sliding of the telescopic tube 2;

[0036] At least two limiting plates 12 are provided inside the main body 1 to cooperate with the collar 22 to limit the extreme extension and retraction positions of the telescopic tube 2 in two directions.

[0037] Furthermore, one end of the sealing ring 4 is embedded in the second annular groove, while the other end remains in contact with the inner wall of the first annular groove;

[0038] The longitudinal dimension of the first annular groove is larger than that of the second annular groove, so that the sealing ring 4 is kept in the first annular groove during the movement of the telescopic tube 2, thereby ensuring its sealing effect.

[0039] Furthermore, the locking mechanism 3 is used to lock the telescopic tube 2 to the main body 1, including:

[0040] A steel ball 31 is disposed in the slot to fit into the hemispherical groove, and the steel ball 31 can slide within the slot.

[0041] A return spring 32 is provided in the slot, with one end fixedly connected to the inner wall of the slot and the other end fixedly connected to the steel ball 31. The return spring 32 is used to provide force to the steel ball 31.

[0042] The locking mechanism 3 has at least two sets, corresponding to the number of slots.

[0043] Without external force control, the telescopic tube 2 is locked to the main body 1 by the locking mechanism 3. When telescopic movement is required, simply pull the telescopic tube 2. When the applied force exceeds the locking force of the return spring 32, the telescopic tube 2 can move outward (inward), causing the steel ball 31 to move into the slot and compressing the return spring 32. When the slot on the telescopic tube 2 moves to the next hemispherical slot position, the return spring 32 is no longer under force, driving the steel ball 31 to move into the hemispherical slot and creating a "click" sound.

[0044] Its scalable and adjustable design makes it applicable to a wider range of scenarios, and it is reusable with a higher reuse rate.
