Description

Technical Field

[0001] The utility model belongs to the technical field related to gas springs, and specifically relates to a bidirectional damping gas spring. Background Art

[0002] Gas springs are widely used. The working principle of gas springs is to fill an inert gas or an oil-gas mixture into a closed pressure cylinder to make the pressure in the cavity many times higher than the atmospheric pressure. The pressure difference generated by the cross-sectional area of ​​the piston rod being smaller than the cross-sectional area of ​​the piston is used to achieve the movement of the piston rod. The existing gas spring technology has the following problems: when an accident occurs to the gas spring, it is impossible to prevent it from continuing to work by effective means, which poses certain safety hazards.

[0003] For example, a stiffness-adjustable bidirectional damping gas spring disclosed in the authorization announcement number CN 214036644 U has solved the following problems in the existing gas spring technology: the existing gas spring bears a large load when in use, so if the damping force is small, damage may occur between the piston rod and the pressure tube, thereby reducing the life of the gas spring. However, it does not solve the control problem of the bidirectional damping gas spring mechanism and the problem of accidental manual interruption of the bidirectional damping gas spring mechanism. Utility Model Content

[0004] The utility model aims to provide a bidirectional damping gas spring to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Preferably, a gas spring piston is fixedly provided at the top end of the main piston rod, which has the beneficial effect of transmitting kinetic energy and pressure. When the gas is compressed, the piston pushes downward to increase the pressure. When released, the piston moves upward to release the pressure to produce a rebound effect, thereby controlling the damping performance of the gas spring.

[0009] Preferably, a piston rubber protection plate is fixedly provided on one side of the gas spring piston, which has the beneficial effect of effectively reducing the noise generated by vibration during the operation of the mechanical equipment, absorbing the vibration and dispersing it, thereby reducing the propagation and impact of the vibration, and effectively reducing the damage to the gas spring piston caused by vibration caused by impact or external vibration during the operation of the equipment.

[0010] Preferably, a damping accommodating bin is fixedly provided at the bottom end of the damping storage plate, and a support rod is fixedly provided at the bottom end of the damping accommodating bin. The beneficial effect is that the damping oil required by the bidirectional damping type gas spring mechanism can be accommodated, and the semi-sealed structure is adopted to greatly reduce its leakage during use, thereby extending its service life and stably setting the damping accommodating bin on the bidirectional damping type gas spring mechanism.

[0011] Preferably, a limiting plate is fixedly provided on the other side of the first safety valve. The beneficial effect is that when the bidirectional damping gas spring mechanism fails and cannot be adjusted by the control device, the first safety valve is manually pushed in to drive the limiting plate to stop the operation of the bidirectional damping gas spring mechanism, thereby preventing the occurrence of hidden dangers caused by its continued operation due to the failure.

[0012] Preferably, a top damping adjustment button is fixedly provided on one side of the control device, and a bottom damping adjustment button is fixedly provided on one side of the top damping adjustment button. The beneficial effects are: adjusting the damping level of the top main piston rod and the auxiliary piston rod to meet the damping requirements under different working conditions, and adjusting the damping level of the bottom main piston rod and the auxiliary piston rod to meet the damping requirements under different working conditions.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When operating the equipment, first check to ensure that there is no leakage of damping oil in the damping storage plate and other faults. According to the needs of the mechanical equipment, use the top damping adjustment button and the bottom damping adjustment button to adjust the damping level required by the mechanical equipment. Fix the two-way damping gas spring mechanism in a suitable position, and the two-way damping gas spring mechanism can start working. If a fault occurs during use and the top damping adjustment button and the bottom damping adjustment button cannot be adjusted, manually push the first safety valve and the second safety valve to interrupt the internal limiting plate.

[0015] 2. The benefit of this equipment is that it is equipped with a damping accommodating chamber and a support rod to accommodate the damping oil required by the bidirectional damping gas spring mechanism, and adopts a semi-sealed structure to greatly reduce its leakage during use, extend its service life and firmly set the damping accommodating chamber on the bidirectional damping gas spring mechanism. It is equipped with a limiting plate, and when the bidirectional damping gas spring mechanism fails and cannot be adjusted through the control device, the first safety valve can be manually pushed in to drive the limiting plate to stop the operation of the bidirectional damping gas spring mechanism, thereby preventing the occurrence of hidden dangers caused by its continued operation due to a failure. It is equipped with a control device to adjust the damping level of the top main piston rod and the auxiliary piston rod to meet the damping requirements under different working conditions, and to adjust the damping level of the bottom main piston rod and the auxiliary piston rod to meet the damping requirements under different working conditions.
