Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A buffering and shock-absorbing automobile pipeline clamp structure comprises a base 1 and a clamping block 2. The two clamping blocks 2 are symmetrically arranged and are respectively slidably connected to the upper end surface of the base 1.

[0024] A buffer mechanism is provided on the base 1, and the buffer mechanism includes a sealing chamber 3, a piston plate 4, a fixed block 5, a connecting rod 6, an airbag 7, and a T-shaped block 8. The sealing chamber 3 is fixedly connected to the upper end surface of the base 1, and the piston plate 4 is sealingly and slidably connected to the inner side wall of the sealing chamber 3. The fixed block 5 is fixedly connected to the side wall of the clamping block 2, and the connecting rod 6 is fixedly connected between the fixed block 5 and the piston plate 4. The connecting rod 6 is slidably connected to the sealing chamber 3. An arc groove is provided on the side wall of the clamping block 2, and the airbag 7 is fixedly connected in the arc groove. An air guide tube 20 is fixedly connected between the airbag 7 and the sealing chamber 3, and the air guide tube 20 passes through the side wall of the clamping block 2. The air guide tube 20 is fixedly connected to the clamping block 2, and the air guide tube 20 is relatively long and will not break when stretched. The T-shaped block 8 is fixedly connected to the lower end surface of the clamping block 2, and a slide groove is provided on the upper end surface of the base 1. The T-shaped block 8 is slidably connected in the slide groove, and a shock-absorbing spring 19 is fixedly connected between the T-shaped block 8 and the base 1.

[0025] Two hollow rods 9 are symmetrically fixedly connected to the side wall of the base 1, one end of the hollow rod 9 is fixedly connected to a suction cup 10, the end of the hollow rod 9 away from the suction cup 10 is fixedly connected to a circular plate 11, the outer surface of the circular plate 11 is slidably connected to an air cylinder 12, the hollow rod 9 and the air cylinder 12 are slidably connected, the hollow rod 9 and the air cylinder 12 are not sealed, the circular plate 11 and the air cylinder 12 are also rotatably connected, a desorption port is provided on the air cylinder 12, a sealing plate 13 is fixedly connected to the side wall of the circular plate 11, the sealing plate 13 is slidably connected to the air cylinder 12, a reset spring 14 is fixedly connected between the air cylinder 12 and the base 1, and a torsion spring 15 is fixedly connected between the circular plate 11 and the air cylinder 12.

[0026] A pull ear 16 is fixedly connected to the side wall of the clamping block 2, a shifting block 17 is fixedly connected to the side wall of the pull ear 16, a shifting plate 18 is fixedly connected to the upper end surface of the air cylinder 12, and the shifting block 17 is slidably connected to the shifting plate 18. When the air cylinder 12 is pressed down, the shifting plate 18 and the shifting block 17 are on the same horizontal line.

[0027] In the utility model, when in use, first insert two fingers into the two pull ears 16 respectively, and use force outward to separate the two clamping blocks 2. The clamping blocks 2 drive the fixing block 5 and the T-shaped block 8 to move away from each other, and compress the shock-absorbing spring 19. The fixing block 5 drives the connecting rod 6 and the piston plate 4 to move away from the sealing chamber 3. Because the connecting rod 6 and the sealing chamber 3 are not sealed, as the piston plate 4 moves away from the sealing chamber 3 and the space between the piston plate 4 increases, the internal negative pressure is present, and the gas in the airbag 7 enters the sealing chamber 3 along the air guide pipe 20 under the action of pressure, and the automobile pipelines that need to be limited are put into the two The pull ear 16 is released between the arc grooves of the clamping block 2. Under the elastic force of the shock-absorbing spring 19, the clamping block 2 and the T-shaped block 8 are reset. The clamping block 2 drives the fixing block 5 and the connecting rod 6 to reset. The piston plate 4 moves toward the sealing chamber 3. The space between the piston plate 4 and the sealing chamber 3 becomes smaller and presents a positive pressure. Under the action of pressure, the gas returns to the airbag 7 along the air guide tube 20. The pipeline is bound in the arc groove and is tightly wrapped by the airbag 7. Tube bundles of different numbers and diameters can be fixed, and the airbag 7 can fit the gaps between the tube bundles to make the connection tighter and provide a certain buffer.

[0028] After the pipeline is fixed, the base 1 is attached to the car, and the two air cylinders 12 are pressed. The air cylinder 12 slides toward the base 1, and the gas between the air cylinder 12 and the annular plate 11 slips out from the contact part between the suction cup 10 and the car along the hollow rod 9. The air cylinder 12 is under negative pressure, and the suction cup 10 firmly sucks the car, thereby firmly fixing the pipeline to prevent it from swinging back and forth when it is vibrated. It is simple and quick to fix. When it needs to be disassembled, just pull the pull ear 16 outward to the bottom, and the pull ear 16 drives the shift block 17 to move toward the shift plate 18. The shift block 17 drives the shift plate 18 to rotate, and the rotation of the shift plate 18 drives the air cylinder 12 to rotate, so that the sealing plate 13 is misaligned with the desorption port, and the outside air enters the air cylinder 12 from the desorption port. The suction cup 10 no longer has adsorption force, and under the elastic force of the reset spring 14, the air cylinder 12 moves up, and at the same time, the two clamping blocks 2 are separated from each other, and the clamping block 2 can be taken out of the pipeline. After releasing the hand, the shift block 17 is reset and no longer squeezes the shift plate 18. Under the action of the torsion spring 15, the air cylinder 12 is reset, and the sealing plate 13 covers the desorption port again. The disassembly is very simple and quick.

[0029] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
