[0043] In this embodiment 2,

[0044] As Figs. 1-3 The working principle of the utility model is as follows:

[0045] When the door body starts to close, the damping rod 5 moves in the barrel body 1. Under normal circumstances, the movement of the damping rod 5 will be affected by the damping force generated by the damping assembly 2, and the closing speed of the door body will be slowed down;

[0046] However, because the inner wall of the barrel body 1 is provided with the acceleration unit 3, that is, a plurality of interval distributed oil passing grooves 4. When the damping rod 5 moves, the oil can flow more smoothly through the oil passing groove 4, thereby reducing the damping effect;

[0047] The depth design (uniform or from shallow to deep) of the oil passing groove 4 will affect the flow speed and flow of the oil, and then adjust the degree of damping reduction;

[0048] When the door body is closed to a certain extent, the reset elastic piece 14 will play a role, helping the damping rod 5 to return to the initial position, and preparing for the next door closing action.

[0049] The front barrel head piece 8 and the rear barrel head piece 9 in the barrel head assembly 7 respectively play the role of sealing and fixing, ensuring that the oil does not leak and maintaining the stable operation of the device. The oil storage groove 13 in the rear barrel head piece 9 provides sufficient oil reserve for the device, ensuring its long-term stable work.

[0050] In this embodiment,

[0051] As Figs. 1-3 As shown in the utility model, when opening and closing the door body, the damping effect can be effectively reduced in the process of opening and closing the door, realizing the rapid opening and closing of the door body, greatly improving the operation efficiency, especially suitable for scenes with high requirements for opening and closing the door body. The careful design of the oil passing groove 4, whether the depth is consistent or from shallow to deep, can accurately control the degree of damping reduction according to the actual demand, so that the opening and closing speed of the door body is just right, which not only meets the demand of rapid closing, but also avoids the impact and safety hidden danger caused by rapid closing.

[0052] The damping assembly 2 and the barrel head assembly 7 cooperate with each other to provide stable damping effect when opening and closing the door, ensuring the smoothness of the opening and closing process of the door body; and can cooperate with the acceleration unit 3 to realize efficient opening and closing action. The excellent sealing design and firm fixing way of the front barrel head piece 8 effectively prevent oil leakage, ensuring the stable and reliable performance of the damping device in long-term frequent opening and closing operation. And the oil storage groove 13 in the rear barrel head piece 9 provides sufficient oil reserve for the device, ensuring the persistence and stability of the damping effect.

[0053] In addition, the reset elastic member 14 on the damping rod 5 quickly resets the device after the door body is closed, and prepares for the next door opening and closing, further improving the fluency and continuity of the entire door opening and closing process.

[0054] In this embodiment 4,

[0055] As Figs. 1-3 shown, in the utility model, the damping rod 5 acts in the cylinder body 1, the floating piston unit 6 acts along with the action of the damping rod 5, the oil slowly flows to the rear end of the damping rod 5 sleeve through the floating piston unit 6, and damping force is generated, when the damping rod 5 moves to the acceleration unit 3 arranged on the inner wall of the cylinder body 1, the acceleration unit 3 includes a plurality of oil passing grooves 4 (the depths of the oil passing grooves 4 are designed to be consistent or from shallow to deep) distributed at intervals along the inner wall of the cylinder body 1, and the oil passing grooves 4 accelerate the oil flow to reduce the damping effect, so that when the door body is opened, the damping rod 5 is accelerated to open in the first half of the cylinder body 1, and the damping rod 5 slows down to open in the second half of the cylinder body 1, when the door body is closed, the damping rod 5 slows down to close in the first half of the cylinder body 1, and the damping rod 5 accelerates to close in the second half of the cylinder body 1 (at the same time, the damping rod 5 is prevented from being unable to close tightly due to the damping effect caused by the force applied by the reset elastic member 14 in the first half of the cylinder body 1).
