Description
Technical Field
[0001] The utility model relates to the field of pipeline connectors, in particular to a pipeline connector which is easy to adjust. Background Art
[0002] A pipe connector is a device specially designed to connect pipes. It is usually made of materials such as stainless steel and rubber, and can ensure the sealing and pressure-bearing performance between pipes.
[0003] In the existing pipe connection method, if two pipe ends need to be connected, the staff usually use a pipe connector. First, the staff put the pipe connector on the two pipe ends that need to be connected, and then fix the pipe connector between the two pipes by tightening the bolts on the side of the pipe connector. During the pipe installation process, the staff often encounter the situation where the pipe is not in flat contact with the ground, which may cause the connection to be subjected to additional stress, affecting the stability and sealing of its connection. Especially when the pipe connectors are mostly fixed in size, it is difficult to flexibly adapt to various terrain conditions. In order to make the pipe fit better with the ground, the pipe may need to be cut on site to adjust its length or shape to make it more in line with the installation requirements. The cut pipe ends may need to be welded to restore their structural integrity and connection capabilities. These extra tasks not only extend the time of pipe installation, but also increase labor costs.
[0004] In view of the above problems, it is necessary to design a pipe connector that is easy to adjust. Utility Model Content

[0011] Furthermore, a U-shaped groove is provided on the mounting plate, and the piston rod is slidably engaged with the U-shaped groove.
[0012] The beneficial effects of the present invention are as follows: through the cooperation of the piston cylinder and the piston rod, the gas in the piston cylinder will be compressed during the movement of the piston rod, and the compressed gas will be transported to the annular air cushion through the air supply pipe, causing the annular air cushion to expand. When the annular air cushion is fully expanded, it can tightly block the gap between the pipeline and the second connector, thereby achieving effective sealing and preventing gas or liquid leakage.

DETAILED DESCRIPTION
[0018] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.
[0019] Embodiment: A pipe connector that is easy to adjust, such as Figures 1-4As shown, it includes a first connector 1, a second connector 2, an annular air cushion 4, an air supply pipe 6, a first guide sleeve 7, a second guide sleeve 8, a piston rod 10, a piston rod 11, a mounting plate 12, a wedge block 13 and a spring 14. The second connector 2 is slidably connected in the first connector 1, and a first slide groove 3 is provided on the lower side of the first connector 1. The second connector 2 slides with the first slide groove 3 to ensure that it can move smoothly in the first connector 1. A mounting groove 5 is provided on the second connector 2, in which the annular air cushion 4 can be placed. An annular air cushion 4 is placed inside the mounting groove 5. The annular air cushion 4 is made of a polymer material to ensure its durability and sealing performance. A second slide groove 9 is symmetrically provided on the first connector 1, and a first guide sleeve 7 is slidably connected to the second slide groove 9. The first guide sleeve 7 passes through the second connector 2, and the air supply pipe 6 is connected between the two first guide sleeves 7. The air supply pipe 6 is connected to the annular air cushion 4 so as to inflate the inside of the annular air cushion 4. The front side of the first connector 1 is connected to the second guide sleeve 8. The air supply pipe 6 is located inside the second guide sleeve 8 to protect the air supply pipe 6 and guide the direction of the gas. A piston rod 10 is installed on the first connector 1. The annular air cushion 4 is connected to the front side of the piston rod 10. The lower end of the piston rod 10 is connected to the piston rod 11. The up and down movement of the piston rod 11 can compress or release the gas, thereby controlling the expansion or contraction of the annular air cushion 4. The rear side of the first connector 1 is symmetrically connected to a mounting plate 12. The mounting plate 12 is arc-shaped. A U-shaped groove is provided on the mounting plate 12. The piston rod 11 slides in cooperation with the U-shaped groove to ensure the linear movement of the piston rod 11. A wedge block 13 is slidably connected to the mounting plate 12. The number of wedge blocks 13 is not less than two. A spring 14 is connected between the wedge block 13 and the mounting plate 12.
[0020] When it is necessary to use this device, during the pipeline installation process, if it is found that the pipeline is not in contact with the ground and the pipeline connector needs to be adjusted, the staff pulls the second connector 2 to move to the left along the first connector 1 and the first slide 3. The movement of the second connector 2 drives the annular air cushion 4, the first guide sleeve 7 and the air supply pipe 6 to move to the left along the second slide 9. The air supply pipe 6 maintains its smooth movement under the guidance of the second guide sleeve 8. When the second connector 2 moves to a suitable position, the second connector 2 is released to stabilize the second connector 2 in this position. The first connector 1 is then put on the two ends of the pipelines to be connected, and the pipeline is gently pushed to move inward along the first connector 1 until the pipeline enters the second connector 2. The above operation is repeated to ensure that the other pipeline can also enter the second connector smoothly. 2, since there may be a gap between the pipeline and the second connector 2, when the gap needs to be blocked, the staff pulls the wedge block 13 to move upward, the spring 14 is compressed, and then the piston rod 10 is started. The piston rod 11 moves upward along the U-shaped groove on the mounting plate 12. The movement of the piston rod 11 can compress the gas in the piston rod 10, forcing the gas to enter the annular air cushion 4 through the air supply pipe 6, causing the annular air cushion 4 to expand. When the annular air cushion 4 expands to a large enough size to tightly fill the gap between the pipeline and the second connector 2, the piston rod 10 is immediately closed, and the wedge block 13 is released. Under the reset action of the spring 14, the wedge block 13 moves downward along the mounting plate 12, and the wedge block 13 moves to contact and fix the piston rod 11, thereby maintaining the expansion state of the annular air cushion 4 and ensuring its good sealing effect.
