[0002] A connecting elbow is a component used to change the direction of fluid in a piping system. It typically consists of a curved section of pipe. Conduit is a type of piping system used to protect wires and cables. Typically made of metal or plastic, it safely conceals wires and cables within walls, ceilings, or floors. To facilitate later inspection and replacement of wires and cables, some buildings lay conduit along the bottom of building walls.

Moreover, when installing the connecting elbows, it is difficult to match the connecting elbows due to the carrying of connecting elbows with various bending angles, thereby reducing the installation efficiency.

DETAILED DESCRIPTION

[0034] The present invention provides Figures 1 to 6 The multi-directional adaptive pipe connection elbow shown includes a first tube body 1, a second tube body 2, and a hose 3. The hose 3 is connected between the first tube body 1 and the second tube body 2. The first tube body 1 and the second tube body 2 can be made of, but are not limited to, hard plastic, while the hose 3 is made of a soft material such as rubber. The first tube body 1 and the second tube body 2 are connected to the external pipeline. The hose 3 is connected between the first tube body 1 and the second tube body 2, so that the angle between the first tube body 1 and the second tube body 2 can be adjusted, achieving multi-directional adaptive adjustment.

[0035] A square frame 10 is provided between the first tube body 1 and the second tube body 2, and the square frame 10 surrounds the outside of the hose 3; a first fixing sleeve 5 is fixedly connected to the first tube body 1, and a second fixing sleeve 6 is fixedly connected to the second tube body 2. Both sides of the square frame 10 are rotatably connected to a rotating shaft 9, and a first rotating plate 7 and a second rotating plate 8 are rotatably provided on the rotating shaft 9. The end of the first rotating plate 7 away from the rotating shaft 9 is fixedly connected to the first fixing sleeve 5, and the end of the second rotating plate 8 away from the rotating shaft 9 is fixedly connected to the second fixing sleeve 6.

[0036] The first fixing sleeve 5 and the second fixing sleeve 6 can rotate about the rotating shaft 9 , that is, the angle between the first fixing sleeve 5 and the second fixing sleeve 6 is adjustable, thereby making the angle between the first tube body 1 and the second tube body 2 adjustable.

[0037] A control component is arranged between the first tube body 1 and the second tube body 2, and the control component includes an arc rod 11, an arc cylinder 12, a piston block 13 and an air cavity 14. The arc rod 11 is fixedly connected to the second fixed sleeve 6, and the arc cylinder 12 is fixedly connected to the first fixed sleeve 5. The piston block 13 is slidably arranged inside the arc cylinder 12, and the end of the arc rod 11 away from the second fixed sleeve 6 is slidably arranged inside the arc cylinder 12. The piston block 13 is fixedly connected to the arc rod 11, and an air cavity 14 is formed between the piston block 13 and the inner wall of the arc cylinder 12, and the air cavity 14 is located on the side of the piston block 13 close to the arc rod 11.

[0038] The outer diameter of the arc rod 11 is smaller than the inner diameter of the arc tube 12 , so that the air cavity 14 has a certain volume.

[0039] When the angle between the first tube body 1 and the second tube body 2 on the side close to the control component becomes smaller, the arc rod 11 is retracted into the interior of the arc cylinder 12, the piston block 13 moves inside the arc cylinder 12 toward the first tube body 1, and the air cavity 14 becomes larger; when the angle between the first tube body 1 and the second tube body 2 on the side close to the control component becomes larger, the arc rod 11 extends from the interior of the arc cylinder 12, the piston block 13 moves inside the arc cylinder 12 toward the second tube body 2, and the air cavity 14 becomes smaller.

[0040] The control assembly, the first fixing sleeve 5 and the second fixing sleeve 6 form a triangular support and reinforcement structure, thereby improving the stability of the pipe connection elbow during use.

[0041] To secure the arc rod 11 and arc tube 12, a locking assembly is provided on the arc tube 12 to cooperate with the arc rod 11. The locking assembly includes a threaded hole 15 and a bolt 16. The threaded hole 15 is provided on the arc tube 12 at the end away from the first fixing sleeve 5. The bolt 16 is threadedly connected to the interior of the threaded hole 15 and is pressed into the arc rod 11. In actual use, a sealing gasket is provided at the threaded hole 15 to ensure the sealing of the air cavity 14, which can be adjusted according to specific usage conditions.

[0042] The operator rotates the bolt 16 to release the extrusion limit on the arc rod 11. At this time, the arc rod 11 can be controlled to slide inside the arc tube 12, and the angle between the first tube body 1 and the second tube body 2 can be adjusted; after adjustment, the bolt 16 is rotated in the opposite direction to extrude the arc rod 11, and the angle between the first tube body 1 and the second tube body 2 is fixed.

[0043] Taking into account that the hose 3 is prone to deformation after the first tube body 1 and the second tube body 2 are bent, especially at the inner corners and the outer corners, in order to ensure the use efficiency of the pipe connection elbow, a first pulling component is provided at one end of the square frame 10 close to the outer corner of the hose 3. The first pulling component includes a first through hole 17, a first air cylinder 18, a first slide bar 19 and a first fixing plate 20. The first through hole 17 is opened on the square frame 10, and the first air cylinder 18 is fixedly connected to the inside of the first through hole 17. The first slide bar 19 is slidably arranged in the inside of the first air cylinder 18, and the first slide bar 19 passes through the end of the first air cylinder 18 close to the outer corner of the hose 3. The first fixing plate 20 is fixedly connected to the outer corner of the hose 3, and the end of the first slide bar 19 located outside the first air cylinder 18 is fixedly connected to the first fixing plate 20.

[0044] A second pulling assembly is provided at one end of the square frame 10 near the inner corner of the hose 3. The second pulling assembly includes a second through hole 21, a second air cylinder 22, a second slide rod 23 and a second fixing plate 24. The second through hole 21 is opened on the square frame 10, and the second air cylinder 22 is fixedly connected to the inside of the second through hole 21. The second slide rod 23 is slidably arranged inside the second air cylinder 22, and the second slide rod 23 passes through one end of the second air cylinder 22 near the inner corner of the hose 3. The second fixing plate 24 is fixedly connected to the inner corner of the hose 3, and the end of the second slide rod 23 located outside the second air cylinder 22 is fixedly connected to the second fixing plate 24.

[0045] A connecting component is provided between the air cavity 14 and the first tube body 1 and the second tube body 2. The connecting component includes a pipe fitting group 4, which connects the air cavity 14 with the first air cylinder 18 and the second air cylinder 22. The pipe fitting group 4 includes two telescopic tubes, which are respectively connected between the air cavity 14 and the first air cylinder 18 and between the air cavity 14 and the second air cylinder 22.

[0046] Specifically, when the angle between the first tube body 1 and the second tube body 2 becomes smaller, the arc rod 11 is retracted into the interior of the arc cylinder 12, the piston block 13 moves inside the arc cylinder 12 toward the first tube body 1, the air cavity 14 becomes larger, and the pipe group 4 sucks the gas inside the first air cylinder 18 and the second air cylinder 22, the first slide rod 19 is retracted into the interior of the first air cylinder 18, and the outer corner of the hose 3 is pulled, the second slide rod 23 is retracted into the interior of the second air cylinder 22, and the inner corner of the hose 3 is pulled to reduce the deformation of the hose 3, prevent the outer corner from fitting close to the inner corner, and ensure usage efficiency.

[0047] Furthermore, the smaller the angle between the first tube body 1 and the second tube body 2 is, and the greater the deformation is, the more obvious the pulling is.

[0048] The present invention provides a hose 3, a control component, a first pulling component, a second pulling component and other structures. When the first tube body 1 and the second tube body 2 are multi-directionally adaptively adjusted, the inner corners and outer corners of the hose 3 are pulled, thereby reducing the deformation of the hose 3, preventing the outer corner from being close to the inner corner, and improving the utilization efficiency of the pipeline connection elbow.

[0049] In addition, the frame 10 surrounds the outside of the hose 3 to limit the other two sides of the hose 3 other than the inner corner and the outer corner, and cooperates with the pulling of the outer corner and the inner corner of the hose 3 to improve the stability of the hose 3 in use.
