The specific implementation mode is as follows:

as shown in fig. 1 to 3, the following technical solutions are adopted in the present embodiment:

example (b):

a hydraulic cylinder with an energy accumulator for shock absorption comprises a cylinder barrel 1, a piston 2, a piston rod 3, a shell 12, a capsule 13 and a mushroom valve 17, wherein one end of the cylinder barrel 1 is fixedly connected with a cylinder cover 6, the end, far away from the cylinder cover 6, outside the cylinder barrel 1 is fixedly connected with a cylinder bottom 8, the cylinder barrel 1 can be sealed, oil discharging operation is carried out, the piston 2 is connected with the inside of the cylinder barrel 1 in a sliding way, the piston rod 3 is connected with the inside of the piston 2 in a threaded way, the piston 2 can be driven to move back and forth in the cylinder barrel 1, so that work requirements are met, the shell 12 is fixedly connected with the outside of the cylinder bottom 8, the capsule 13 is fixedly connected with one side, far away from the cylinder bottom 8, inside the shell 12, the original shock absorption mode can be replaced, the air pressure inside the capsule 13 can be adjusted, different use requirements can be met, a fixing rod 15 is fixedly connected with one side, far away from the capsule 13, inside the shell 12, a slide bar 16 is fixedly connected inside the fixed rod 15, one end of the slide bar 16, which is close to the capsule 13, is fixedly connected with a bacterial valve 17, a spring 18 is sleeved outside the slide bar 16 and between the bacterial valve 17 and the fixed rod 15, and the bacterial valve 17 can be adjusted according to different pressures, so that the opening and closing of the shell 12 can be controlled.

Further, the one end of piston rod 3 runs through and extends to 6 outsides of cylinder cap and cover and is equipped with gudgeon 4, and the inside sliding connection of gudgeon 4 has pin 5, and the bottom of pin 5 runs through piston rod 3 and extends to gudgeon 4 outsidely, conveniently is connected piston rod 3 and external object, but also can replace original threaded connection mode to protect piston rod 3.

Furthermore, a first oil hole 7 is formed in the cylinder cover 6, and a second oil hole 9 is formed in the cylinder bottom 8, so that oil can be conveniently discharged into the cylinder barrel 1, and different use conditions can be met.

Further, oil return channels 10 are formed in the cylinder cover 6 and the cylinder bottom 8, oil drain valves 11 are arranged in the cylinder cover 6 and the cylinder bottom 8 and located right above the oil return channels 10, pressure relief processing can be performed on oil pressure in the cylinder barrel 1, and therefore the phenomenon that a cylinder row is too large in hydraulic cylinder pressure is avoided.

Further, casing 12 is outside and keep away from one side fixedly connected with inflation valve 14 of jar bottom 8, and inside inflation valve 14's one end extended to capsule 13, can fill the gassing operation to capsule 13 according to the user demand to satisfy different energy storage demands.

Specifically, when the device is used, a worker presses the inside of the capsule 13 through the inflation valve 14 according to a use requirement, so that the inside of the capsule 13 expands inside the housing 12, when one end of the capsule 13 contacts with the mushroom-shaped valve 17, the mushroom-shaped valve 17 pushes the sliding rod 16 to slide inside the fixing rod 15 and extrude the spring 18, at this time, the mushroom-shaped valve 17 seals the housing 12, as shown in fig. 1, at this time, the piston 2 inside the cylinder 1 is located at one side of the cylinder cover 6, when hydraulic oil enters the cylinder cover 6 through the first oil hole 7, the hydraulic oil pushes the piston 2 to drive the piston rod 3 to move inside the cylinder 1 toward the cylinder bottom 8, as shown in fig. 2, when the piston rod 3 moves to the inside of the cylinder bottom 8 and blocks the second oil hole 9, a part of the hydraulic oil enters the inside of the housing 12 through the oil return passage 10 on the cylinder bottom 8, at this time, the hydraulic oil extrudes the mushroom-shaped valve 17 to drive the sliding rod 16 to slide inside the fixing rod 15, at this moment, fungus type valve 17 drives spring 18 and stretches, meanwhile, fungus type valve 17 extrudes capsule 13, because capsule 13 is inside to have certain atmospheric pressure, can produce reaction force this moment, can reduce the speed that piston 2 moved in cylinder 1 is inside, thereby play the absorbing effect to piston 2, can fix gudgeon 4 through pin 5, thereby conveniently be connected the pneumatic cylinder with the outside object, can carry out the pressure release through bleeder valve 11 to the inside oil pressure of cylinder 1 and handle, thereby prevent that the pneumatic cylinder jar from pressing the too big cylinder row phenomenon that appears.
