When the buffer slide plate is subjected to external impact force, the buffer slide plate drives the sliding card block to slide synchronously, thereby achieving buffering of the impact force in this process. When the buffer sleeve When the column moves driven by the buffer slide, the buffer sleeve column synchronously drives the movement of the sliding card column. At the same time, the buffer sleeve column squeezes the buffer spring, and then the buffer spring is squeezed and deformed to buffer the pressure. When the secondary buffer column moves under the action of impact force, the secondary buffer column squeezes the buffer spring during the movement, and then the buffer spring is squeezed and deformed to further buffer the pressure.

[0024] Specifically, the interior of the energy dissipation cylinder 10 includes a compartment 1001, a stabilizing rod 1002, a spring c1003, and an injection chamber 1004. The interior of the energy dissipation cylinder 10 is provided with a compartment 1001, the stabilizing rod 1002 is fixedly installed inside the compartment 1001, the outer wall of the stabilizing rod 1002 is movably sleeved with the spring c1003, the interior of the stabilizing rod 1002 is provided with an injection chamber 1004, the interior of the injection chamber 1004 and the interior of the bottom tube 17 are interconnected, the interior of the injection chamber 1004 is movably sleeved with a piston c1005, and a lubricating member is provided inside the movable rod 3; the lubricating member includes an air storage chamber b301, an movable chamber 302, a mounting plate 303, an extension rod 304, a spring b305, and a piston b306. , sponge head 307, limiting ring plate 308, an air storage chamber b301 is opened inside the movable rod 3, and movable chambers 302 are opened on both sides of the air storage chamber b301. The middle part of the movable chamber 302 is fixedly connected to the mounting plate 303, and the interior of the mounting plate 303 is movably sleeved with the extension rod 304, and one side of the extension rod 304 is movably sleeved with the spring b305, and the outer wall of the spring b305 is fitted and connected with the piston b306, and the other side of the extension rod 304 is fixedly connected to the sponge head 307, and the bottom of the movable rod 3 is fixedly connected to the limiting ring plate 308, and the outer wall of the limiting ring plate 308 and the outer wall of the compartment 1001 are sleeved with each other, and the interior of the air storage chamber b301 is filled with air, and the side of the movable chamber 302 and the side port 5 are connected with each other.

[0025] In this embodiment, when the gas is discharged, it will enter the interior of the movable cylinder 2, and the piston c1005 can squeeze the top gas, so that the gas will enter the interior of the movable rod 3, so that the piston b306 is pushed out by the gas, allowing the sponge head 307 and the spring a4 on the outer wall to rub, and during the friction, the lubricant can be applied to the outer wall of the spring a4, which facilitates lubrication and extrusion.

[0026] Working principle:

[0027] Preparation step 1: inject lubricating liquid into the movable cavity 302, and the sponge head 307 will contact with the lubricating liquid and absorb it.

[0028] Lubrication step two, during the operation of the side port 5, the movable rod 3 fixedly connected to the bottom of the push rod 6 will extend toward the inside of the movable cylinder 2, and during the extension process, the connecting rod 7 will move downward, and at this time the fixed rod 9 will move toward the inside of the energy dissipation cylinder 10. Because the bottom of the fixed rod 9 is fixedly connected to the piston a13, the fixed rod 9 will discharge the air inside the energy dissipation cylinder 10 into the air distribution box 18 during the downward movement. At this time, more air will be stored in the air distribution box 18, and then it will be injected into the injection chamber 1004 through the air vent pipe 16 and the bottom pipe 17. When it enters the injection chamber 1004, it will push the piston c1005 to move upward. At this moment, the piston c1 The air at the top of 005 will move upward and move to the inside of the installation cavity 103. As the gas continues to accumulate inside the installation cavity 103, the pressure increases. The gas pressure will push the piston b306 to extend outward, allowing the piston b306 to push the extension rod 304 to extend outward. At the same time, the sponge head 307 fixedly connected to the outer wall of the extension rod 304 will contact the outer wall of the spring a4. The spring a4 will rub against the sponge head 307 during the deformation process, allowing the lubricating fluid stored in the sponge head 307 to overflow during the friction and be smeared on the surface of the spring a4, which can lubricate the spring a4, reduce friction loss, and increase the practical life of the spring a4.

[0029] Energy dissipation step three, when a rebound force is formed during the squeezing process of spring a4 and spring c1003, the fixed rod 9 will be pulled out from the inside of the energy dissipation cylinder 10, and the piston a13 will draw the exhausted gas back into the inside of the energy dissipation cylinder 10 during the extraction process, and the rebound force generated when the spring is in contact can be offset during the extraction process, and the piston c1005 can also be pulled back to its original position during the extraction process. At the same time, the squeezing of the gas by the piston c1005 will disappear, which leads to the cancellation of the force pushing the piston b306 outward. At that time, the spring b305 will generate a rebound force, which can pull the sponge head 307 back into the active chamber 302 to avoid its continuous friction, thereby saving lubricating fluid, facilitating subsequent lubrication, and improving the use efficiency.
