[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a metal bellows with a buffer structure, including a pipe 3, a U-shaped block 4 is fixedly connected to the top of the pipe 3, the U-shaped block 4 is used to support a sleeve rod 54, a buffer component 5 for buffering the pipe 3 is arranged on the top of the U-shaped block 4, a round rod 7 is arranged on the top of the buffer component 5, the outer wall of the round rod 7 is rotatably connected to a mounting plate 6, a bolt 8 is arranged in the middle of the mounting plate 6, and the mounting plate 6 can be mounted on the wall by the bolt 8, a sealing component 2 is arranged on the outer wall of the pipe 3, the buffer component 5 includes a sleeve rod 1 54, the outer wall of the sleeve rod 1 54 is slidably connected to a sleeve rod 2 51, and the sleeve rod 2 51 is fixedly connected to the outer wall of the round rod 7.

[0028] Reference Figure 2 A piston block 52 is fixedly connected to the left side of the sleeve rod 1 54, and the piston block 52 is connected to the inner wall of the sleeve rod 2 51. When the sleeve rod 1 54 is moved under pressure, the piston block 52 will be driven to move together and the piston block 52 will squeeze the gas in the sleeve rod 2 51. The buffering effect is increased by the compressible property of gas. The piston block 52 and the sleeve rod 2 51 are elastically connected by a spring 1 53. The spring 1 53 connects the piston block 52 and the sleeve rod 2 51, and the spring 1 53 assists in resetting the piston block 52. One end of the spring 1 53 is fixedly connected to the right side of the piston block 52, and the other end of the spring 1 53 is fixedly connected to the inner wall of the sleeve rod 2 51.

[0029] Reference Figure 2 A squeezing rod 55 is hinged on the left side of the piston block 52, and a squeezing block 56 is fixedly connected to the inner wall of the sleeve rod 51. The squeezing block 56 is made of rubber material. When the squeezing rod 55 squeezes the squeezing block 56, the squeezing block 56 will deform, increasing the friction of movement and thus increasing the stabilizing effect.

[0030] Reference Figure 1 , Figure 3 The sealing assembly 2 includes a disc 21, which is fixedly connected to the outer wall of the pipe 1 3. A sealing block 23 is slidably connected to the right side of the disc 21. The sealing block 23 and the disc 21 are elastically connected by a spring 22. The spring 22 connects the sealing block 23 and the disc 21, and the reverse force of the spring 22 causes the sealing block 23 to squeeze the round block, thereby increasing the sealing between the pipe 1 3 and the pipe 2 1. One end of the spring 22 is fixedly connected to the right side of the disc 21, and the other end of the spring 22 is fixedly connected to the left side of the sealing block 23. The right side of the pipe 1 3 is threadedly connected to the pipe 2 1, and the outer wall of the pipe 2 1 is fixedly connected to the round block.

[0031] Working principle: First check whether the various accessories of the device can be used normally. If they can be used normally, thread the pipe 21 to the right side of the pipe 13. When the pipe 21 rotates and moves to the left, the round block will contact the sealing block 23. When the round block contacts the sealing block 23, the sealing block 23 will receive pressure and move backward to squeeze the spring 22. Through the reverse action force of the spring 22, the sealing block 23 squeezes the round block, thereby increasing the sealing of the pipe 13 and the pipe 21.

[0032] Then the mounting plate 6 is mounted on the wall by means of bolts 8. When the pipe 1 3 is subjected to pressure, the sleeve rod 1 54 transmits the pressure to the sleeve rod 2 51, and when the sleeve rod 1 54 moves, it drives the piston block 52 to move together to squeeze the gas in the sleeve rod 2 51, and when the piston block 52 moves, it stretches the spring 1 53, and when the piston block 52 moves, it drives the squeezing rod 55 to move and squeeze the squeezing block 56. Since the squeezing block 56 is made of rubber and has the property of deformation, the squeezing block 56 generates friction force to the squeezing rod 55, and cooperates with the piston block 52 to squeeze the gas and the reverse force of the spring 1 53 to buffer the pipe 1 3.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
