Description

Technical Field

[0001] The utility model relates to the field of gas spring energy absorption devices, and more specifically, to a high-efficiency gas spring energy absorption device. Background Art

[0002] Gas spring is an industrial accessory that can perform functions such as support, buffering, braking, height adjustment and angle adjustment.

[0003] When the gas spring is compressed for buffering, its internal air pressure is the key to the hardness of the vibration reduction. When the internal air pressure is high, the spring is compressed harder, and when the air pressure is low, it is softer. When the air is compressed in the cylinder for buffering, the cylinder space is fixed, and the air will be still after being compressed to a certain degree. When the overall pressure is high, the elastic absorption is poor and the buffering degree is low. Utility Model Content

When the compression cylinder is compressed, the air can compress the two groups of energy absorption blocks at the same time, and buffering is performed by the movement of the energy absorption blocks, thereby improving the buffering performance when the pressure is too large, and the pressure absorption degree is high and the buffering degree is high.

[0020] 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.

[0021] Example 1

[0022] See also Figure 1-3 A high-efficiency gas spring energy absorption device comprises a cylinder 1, a compression rod 2 is slidably disposed on the inner surface of the upper end of the cylinder 1, a compression cylinder 3 is fixed to the lower surface of the compression rod 2, a first energy absorption block 4 is slidably disposed on the inner surface of the compression cylinder 3, a compression spring 5 is fixed to the inner surface of the first energy absorption block 4, support cylinders 6 are arranged on both sides of the lower end of the cylinder 1, and rubber balls 8 and a second energy absorption block 7 are placed in the support cylinders 6;

[0023] The upper surface of the compression spring 5 is fixed to the inner surface of the compression cylinder 3, the outer surface of the compression cylinder 3 is sleeved with a first sealing ring 30, and the outer surface of the first energy absorbing block 4 is sleeved with a second sealing ring 40, so as to facilitate sealing when compressing air;

[0024] The outer surface of the support tube 6 is provided with a convex opening, which is connected to the inner surface of the cylinder 1 through a thread, and is easy to install. The outer end convex opening of the support tube 6 is sleeved with a gasket 10, and is easy to seal during installation;

[0025] A hexagonal groove 9 is provided on the back of the support tube 6, which is convenient for the installation and removal by inserting and twisting a hexagonal wrench, and is easy to use;

[0026] When in use, the compression rod 2 drives the compression cylinder 3 to descend and compress the air inside the cylinder 1 for pneumatic vibration reduction. When the pressure is relatively high, the air becomes static after being compressed to a certain degree. At this time, the overall vibration reduction is relatively hard. At this time, the air pressure can push open the first energy absorbing block 4 and the second energy absorbing block 7, which are buffered by the compression spring 5 and the rubber ball 8 respectively, and further buffer support is performed to improve the buffer support force and the buffer elastic energy absorption efficiency, which is easy to use.

[0027] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
