[0001] This utility model relates to the field of pressure pipe connection technology, specifically a self-locking pressure pipe quick connector. Background Technology

[0002] Pressure pipelines refer to all pipelines that withstand internal or external pressure, regardless of the medium inside. Pressure pipelines are a part of pipelines used to transport, distribute, mix, separate, discharge, meter, control, and stop the flow of fluids. They are assemblies consisting of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports.

[0003] When connecting pressure pipelines, most of the time they are fixed by thread or bolts. However, this method is relatively troublesome when installing or disassembling pressure pipelines, and it causes inconvenience to the staff.

[0004] Therefore, we propose a self-locking quick-connect pressure pipe to solve the problems mentioned above. Utility Model Content

[0007] Furthermore: the pressing assembly includes a drive ring slidably installed inside the adjustment chamber, one side of the drive ring is fixedly connected to one end of the locking rod, and a plurality of elastic support elements are fixedly attached to the other side of the drive ring, with one side of the elastic support elements being fixedly connected to the inner wall of the adjustment chamber.

[0008] Furthermore: a plurality of push plates are fixed on the outer surface of the drive ring along the circumferential direction; a sliding groove for cooperating with the push plates is opened on the outer surface of the locking cylinder along the axial direction; and one side of the push plate extends through the sliding groove to the outside of the locking cylinder.

[0009] Furthermore: at least two guide rods are fixed inside the adjustment chamber along the axial direction, and the drive ring is provided with guide holes; and the drive ring is slidably mounted on the guide rods through the guide holes.

[0010] Furthermore, multiple locking slots and locking blocks are provided respectively; the spacing between adjacent locking slots is the same as the spacing between adjacent locking blocks.

[0012] The beneficial effects of this utility model are: During the assembly of pressure pipelines, this invention applies pressure to the locking rod on the mounting cylinder via a locking block at the end of the pressure pipeline. This allows the locking block to push the locking rod as it moves within the mounting groove. When the pressure pipeline rotates the locking block into the locking groove, the pressing component resets the locking rod and locks the locking block, thus quickly securing the pressure pipeline. This design is convenient and easy for workers to operate, and the pipeline is highly secure and unlikely to detach. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0016] A self-locking pressure pipe quick connector is provided, which is a connector 2 installed between two pressure pipes 1 and serves to connect the pressure pipes 1.

[0017] In detail: the connector 2 includes a mounting cylinder 201, and a locking cylinder 202 is integrally formed on the outer surface of the mounting cylinder 201. Two adjustment chambers 203 are formed between the outer side wall of the mounting cylinder 201 and the inner side wall of the locking cylinder 202. A pressing component is installed inside each adjustment chamber 203. The pressing component is used to reset the locking rod 4. In detail: The pressing assembly includes a drive ring 301, which is slidably installed inside the adjusting chamber 203 along the axial direction. Several locking rods 4 are equidistantly fixed on one side of the drive ring 301 along the circumferential direction, with one end of each locking rod 4 extending to the outside of the locking cylinder 202. Several elastic support elements 302 are equidistantly fixed on the other side of the drive ring 301. It should be noted that the elastic support elements 302 are compression springs, and one end of each elastic support element 302 is fixedly connected to the inner wall of the adjusting chamber 203. The elastic support elements 302, when pressed, serve to reset the drive ring 301. It should also be noted that a push plate 303 is fixed to the outer surface of the drive ring 301, and a groove 304 is formed along the length of the outer surface of the locking cylinder 202. One end of the push plate 303 extends through the groove 304 to the outside of the locking cylinder 202. Through the push plate 303, the operator can move the drive ring 301.

[0018] In detail: Inside the adjusting chamber 203, a guide rod 8 is fixed along the axial direction, and preferably there are two guide rods 8. The drive ring 301 is provided with a guide hole 9 corresponding to the guide rod 8. The drive ring 301 is slidably mounted on the guide rod 8 through the guide hole 9. The cooperation between the guide rod 8 and the guide hole 9 plays a role in limiting the drive ring 301, preventing the drive ring 301 from rotating or shaking during use, and improving the stability of the drive ring 301.

[0019] The outer surface of the mounting cylinder 201 is provided with a plurality of mounting grooves 5 at equal intervals along the circumferential direction, and one end of the locking rod 4 is slidably installed inside the mounting groove 5. It should be noted that a locking groove 6 is provided on one side of the mounting groove 5. It should be noted that the number of locking grooves 6 is preferably multiple. Through the cooperation of several locking grooves 6 and several locking blocks 7, the pressure pipe 1 and the connector 2 are further secured to prevent them from falling off during use. Through the cooperation of the locking rod 4, the mounting groove 5 and the locking groove 6, the locking block 7 at the end of the pressure pipe 1 is locked to prevent the pressure pipe 1 from falling off the connector 2 during use.

[0020] Several rows of locking blocks 7 are fixed at equal intervals along the circumference at the end of the pressure pipe 1. It should be noted that the spacing between adjacent locking blocks 7 is the same as the spacing between adjacent locking grooves 6. When the pressure pipe 1 is connected to the connector 2, each locking block 7 can rotate into the corresponding locking groove 6, thereby reinforcing the pipe and preventing the pressure pipe 1 from falling off the connector 2. It should be noted that a support ring 10 is also fixed to the inner end wall of the pressure pipeline 1, and a sealing gasket (not shown in the figure) is placed on the side of the support ring 10 facing the mounting cylinder 201. The sealing gasket plays a sealing role and reduces the occurrence of air leakage in the pressure pipeline 1.

[0021] When connecting two pressure pipes 1, first place the connector 2 between the two pressure pipes 1, then align the locking block 7 on the pressure pipe 1 with the mounting groove 5 and apply pressure, so that one end of the pressure pipe 1 can move into the mounting cylinder 201; several locking blocks 7 can apply pressure to several locking rods 4 respectively, and several locking rods 4 can push the same drive ring 301, so that the drive ring 301 can move inside the adjusting chamber 203 and squeeze the elastic support element 302. If the pressure pipe 1 is fully inserted into the upper part of the mounting cylinder 201... When the pressure pipe 1 is rotated, it can drive several locking blocks 7 to rotate, and each locking block 7 can rotate into the corresponding locking groove 6. Since the locking blocks 7 and locking rods 4 are currently misaligned, the elastic support element 302 returns from the compressed state to its original state and pushes the drive ring 301 to move, so that the drive ring 301 can push several locking rods 4 to move, so that several locking rods 4 can move inside the mounting groove 5 respectively, so that the side wall of the locking rod 4 abuts against the locking block 7, thereby achieving the locking effect.
