Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a quick-insert joint angle adjustment and rotation mechanism. Background Technique

[0002] Pipe joints are widely used in the connection between pipelines for transporting oil, water, gas, etc. Generally, they can be divided into straight-through joints, L-shaped joints, and T-shaped joints. Among them, the L-shaped joint includes an L-shaped joint body, and threads are provided at both ends of the L-shaped joint body. During docking, as long as the nut provided on the hose is screwed onto the thread of the L-shaped joint body, the purpose of pipeline connection can be achieved.

[0003] However, during the connection process, generally a tool wrench needs to be used to achieve the tightening purpose. In this way, the docking is time-consuming and laborious, and the docking speed is slow. Moreover, the L-shaped joint also has such a problem: when one end of the L-shaped joint is connected to the hose and tightened, the other end must be fixed in one direction, and the joint end in this direction cannot guarantee that it can just be connected to another pipeline, especially in a narrow space, thus reducing the installation convenience. Therefore, a quick-insert joint angle adjustment and rotation mechanism is proposed to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a quick-insert joint angle adjustment and rotation mechanism, which has the advantages of improving installation convenience and solves the problem of poor installation convenience.

[0005] To achieve the above object, the utility model provides the following technical solution: A quick-insert joint angle adjustment and rotation mechanism includes two plugs. A flexible connecting pipe is fixedly connected between the two plugs, and an adjusting member is arranged on the plugs;

[0006] The adjusting member includes a support block whose one end is rotatably connected to the top plug. A sleeve rod is rotatably connected to the inner side of the support block. A threaded rod is threadedly connected to the inner side of the sleeve rod. The outer side of the bottom plug is rotatably connected to a connecting ring. The outer side of the connecting ring is fixedly connected to one end of the threaded rod located outside the sleeve rod. One end of the sleeve rod located inside the support block is fixedly connected to a limit ring extending into the interior of the support block;

[0007] A connecting member is arranged at the end of the plug.

[0008] Further, a connecting groove located outside the sleeve rod is opened at one end of the support block close to the sleeve rod, and an annular groove whose one end communicates with the connecting groove and is located outside the limit ring is opened inside the support block.

[0009] Further, a first internal thread located outside the threaded rod is opened on the inner peripheral wall of the sleeve rod, and the first internal thread cooperates with the thread on the outer side of the threaded rod.

[0010] Further, the connecting member includes a joint whose one end is inserted into the inner side of the plug. A supporting block is fixedly connected to the inner side wall of the plug. One end of the joint located inside the plug is fixedly connected with a clamping block whose one end extends into the inside of the supporting block. A rotating ring is threadedly connected to the outer side of the plug. A stop block is fixedly connected to the outer side of the supporting block.

[0011] Further, a groove is formed in the inner side wall of the plug, and the supporting block is fixedly connected to the inner side of the groove. The supporting block is an elastic plastic block.

[0012] Further, an external thread is formed on the outer side of the plug, and a second internal thread is formed on the inner peripheral wall of the rotating ring. The second internal thread is matched with the external thread. One side of the stop block close to the rotating ring is inclined. The upper end part of the rotating ring is concave-shaped.

[0013] Further, a clamping groove located outside the clamping block is formed on one side of the supporting block close to the clamping block. One end of the clamping block located inside the clamping groove is inclined. A sealing ring is embedded on the outer side of the joint.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] 1. For this quick-connect joint angle adjustment and rotation mechanism, since the two plugs are connected by a flexible connecting pipe, when the bottom plug is pushed by rotating the sleeve rod to expand the threaded rod, the distance between the two plugs can be adjusted, so as to adjust the angle of the plugs, improving the adaptability of the entire joint structure.

[0016] 2. For this quick-connect joint angle adjustment and rotation mechanism, when the joint is inserted into the inner side of the plug, the clamping block can be driven to be squeezed into the retaining groove of the support block to pre-fix the plug and the joint. And after rotating the rotating ring to abut against the stop block, the joint and the plug can be firmly fixed, without the need to use tools for installation and fixation, improving the installation convenience.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-2 , a quick-insert connector angle adjustment and rotation mechanism in this embodiment includes two plugs 2. A flexible connecting pipe 1 is fixedly connected between the two plugs 2, and an adjusting member 3 is arranged on the plug 2;

[0023] The adjusting member 3 includes a support block 31 whose one end is rotatably connected to the top plug 2. A sleeve rod 32 is rotatably connected to the inner side of the support block 31. A threaded rod 33 is threadedly connected to the inner side of the sleeve rod 32. A connecting ring 34 is rotatably connected to the outer side of the bottom plug 2. The outer side of the connecting ring 34 is fixedly connected to one end of the threaded rod 33 located outside the sleeve rod 32. One end of the sleeve rod 32 located inside the support block 31 is fixedly connected to a limiting ring 35 extending into the interior of the support block 31;

[0024] In this embodiment, since the two plugs 2 are connected by the flexible connecting pipe 1, when the sleeve rod 32 is rotated to spread the threaded rod 33 and push the bottom plug 2, the distance between the two plugs 2 can be adjusted to adjust the angle of the plug 2, thereby improving the adaptability of the entire joint structure.

[0025] Among them, a connecting groove located outside the sleeve rod 32 is opened at one end of the support block 31 close to the sleeve rod 32. An annular groove is opened inside the support block 31, one end of which communicates with the connecting groove and is located outside the limiting ring 35. One end of the sleeve rod 32 can stably rotate inside the support block 31.

[0026] In addition, a first internal thread is provided on the inner peripheral wall of the sleeve rod 32 and is located outside the threaded rod 33. The first internal thread cooperates with the thread on the outer side of the threaded rod 33, so that the rotating sleeve rod 32 can drive the threaded rod 33 to move and adjust inside it.

[0027] Please refer to Figure 1 or 3. In this embodiment, the connecting member 4 includes a joint 45 whose one end is inserted into the inner side of the plug 2. A support block 43 is fixedly connected to the inner side wall of the plug 2. One end of the joint 45 located inside the plug 2 is fixedly connected to a clamping block 46 extending into the interior of the support block 43. A rotating ring 41 is threadedly connected to the outer side of the plug 2. A stop block 42 is fixedly connected to the outer side of the support block 43.

[0028] In this embodiment, when the plug connector 45 is inserted into the inner side of the plug 2, the clamping block 46 can be driven to be squeezed into the retaining groove of the retaining block 43, so as to pre-fix the plug 2 and the connector 45. After the rotating ring 41 rotates and abuts against the stop block 42, the connector 45 and the plug 2 can be firmly fixed without using tools for installation and fixation, improving the installation convenience.

[0029] Wherein, a groove is formed on the inner side wall of the plug 2, and the retaining block 43 is fixedly connected to the inner side of the groove. The retaining block 43 is an elastic plastic block, so that the retaining block 43 can deform and rotate when being squeezed.

[0030] In addition, external threads are formed on the outer side of the plug 2, and second internal threads are formed on the inner peripheral wall of the rotating ring 41. The second internal threads are matched with the external threads. One side of the stop block 42 close to the rotating ring 41 is inclined, and the upper end of the rotating ring 41 is concave-shaped, so that after the rotating rotating ring 41 abuts against the stop block 42, the stop block 42 and the retaining block 43 can be squeezed and blocked.

[0031] Secondly, a card slot located outside the clamping block 46 is formed on one side of the retaining block 43 close to the clamping block 46. One end of the clamping block 46 located inside the card slot is inclined, and a sealing ring 44 is embedded on the outer side of the connector 45, increasing the sealing performance after the connector 45 and the plug 2 are inserted and abutted.

[0032] The working principle of the above embodiment is as follows:

[0033] Since the two plugs 2 are connected by the flexible connecting pipe 1, when the bottom plug 2 is pushed by rotating the sleeve rod 32 to spread the threaded rod 33, the distance between the two plugs 2 can be adjusted to adjust the angle of the plug 2, improving the adaptability of the entire connector structure. When the plug connector 45 is inserted into the inner side of the plug 2, the clamping block 46 can be driven to be squeezed into the retaining groove of the retaining block 43, so as to pre-fix the plug 2 and the connector 45. After the rotating ring 41 rotates and abuts against the stop block 42, the connector 45 and the plug 2 can be firmly fixed without using tools for installation and fixation, improving the installation convenience.
