The piston and the cylinder are metal pieces, the piston and the cylinder are in hard sealing and in direct contact with each other, the sealing is realized through the tiny clearance fit between the cylinder and the piston, and the sliding between the cylinder and the piston is also in hard friction, so that the piston and the cylinder are in high-speed and high-frequency reciprocating friction, the fit clearance is slightly increased, the sealing performance is lost, and the piston and the cylinder cannot work. Because the fit clearance between the piston and the cylinder is very small, a little impurity enters or water vapor enters to generate corrosion, the shell is clamped and the cylinder is pulled under high friction, and the scrapping is caused. So that the service lives of all the pneumatic vibrators at present are generally low, the use cost is high, and the pneumatic vibrators are difficult to popularize.

In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 1, are merely for convenience in describing the present utility model, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

For the purposes and advantages of the present utility model to become more apparent, the following detailed description of the utility model will be taken in conjunction with the examples, it being understood that the following text is provided to illustrate one or more specific embodiments of the utility model and is not to be construed as limiting the scope of the utility model in any way, but rather as including the strict geometric definition of the terms up and down and left and right as used herein, but including the tolerance for machining or human error, and the specific features of the universal-start anti-seize long life vibrating cylinder as described in detail below:

referring to fig. 1-6, a vibration cylinder with a universal starting anti-seizing shell and a long service life according to an embodiment of the utility model comprises a cylinder barrel 10, wherein a piston cavity 18 is arranged in the cylinder barrel 10, an exhaust cavity 13 is arranged on the right side of the piston cavity 18, a first sealing ring 14 is arranged between the piston cavity 18 and the exhaust cavity 13, the exhaust cavity 13 is communicated with the piston cavity 18, a piston 16 is slidably matched in the piston cavity 18, a second sealing ring 15 is fixed in the periphery of the piston 16, a first sealing ring 14 is fixed in a boss 20, and the second sealing ring 15 and the first sealing ring 14 are made of rubber materials and have larger elasticity.

The longitudinal cross-section of the piston 16 is "T" shaped, with the diameter of the left end of the piston 16 being greater than the diameter of the right portion thereof.

The piston 16 is internally provided with a large through cavity 17 with a left opening, the upper side and the lower side of the large through cavity 17 are communicated with small through cavities 19 which are bilaterally symmetrical, and one ends of the outer sides of the four small through cavities 19 are all provided with openings.

The small diameter portion of the piston 16 is a sliding fit with the boss 20.

The first seal ring 14 is provided annularly around the piston 16, and the first seal ring 14 abuts against the outer periphery of the portion of the piston 16 having a small diameter.

The second sealing ring 15 is annularly arranged with the piston 16 as a center, and the second sealing ring 15 is abutted against the inner wall of the piston cavity 18.

The upper side of the piston cavity 18 is communicated with an air inlet 11 with an upward opening, and the left end of the piston 16 is positioned at the left side of the air inlet 11.

The upper side of the exhaust cavity 13 is communicated with an upward opening exhaust port 12.

The specific working process of the utility model comprises the following steps:

gas enters the space on the right of the left end of the piston 16 through the gas inlet 11, and then enters the space on the left of the piston 16 through the small through cavity 19 and the large through cavity 17 on the left, so that the space pressure on the left of the piston 16 is increased, and the piston 16 is pushed to move rightward.

When the small through chamber 19 on the right side enters the exhaust chamber 13, air in the piston chamber 18 is discharged through the large through chamber 17, the small through chamber 19 on the right side, the exhaust chamber 13, and the exhaust port 12, so that the pressure in the piston chamber 18 is reduced.

At this time, the left small through cavity 19 is located at the first sealing ring 14, at this time, the space on the left end and the right side of the piston 16 is in a closed state, and gas enters the space through the gas inlet 11, so that the pressure in the space is increased, and the piston 16 is pushed to move leftwards, so that the left-right reciprocating motion is realized.

During the left-right reciprocation of the piston 16, since the piston 16 is isolated from direct contact with the inner wall of the piston chamber 18 by the second seal ring 15, the piston 16 is isolated from direct contact with the boss 20 by the first seal ring 14, thereby minimizing wear between the piston 16 and the inner wall of the piston chamber 18, and between the piston 16 and the boss 20.

Meanwhile, when water vapor is rusted, the second seal ring 15 and the first seal ring 14 are compressed flexibly to compensate for the bulge or the dent caused by the rusting, thereby ensuring the tightness of the utility model.
