Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
As shown in fig. 1, the utility model relates to a quick reset hydraulic buffer, including casing 2, piston 5 pole, spring and steel ball 1, be equipped with piston 5 in the casing 2, and piston 5 still cup joints in piston 5 pole, 2 settings of casing are stretched out to piston 5 pole one end, and the other end is contradicted with the compression spring 3 of locating in the casing 2 and is linked to each other, and wherein 5 pole surfaces of piston are equipped with director 8 along the axial, the hole has been seted up to casing 2 bottom, and on the hole terminal surface was located to the compression spring 3 other end, be equipped with steel ball 1 in the hole. And flexible seals are arranged between the guide body 8 and the shell 2 and between the guide body 8 and the piston 5 rod. In this embodiment, as shown in fig. 1 or fig. 2, the bottom of the piston 5 is provided with a shoulder, and the medium flows in one direction along the second clearance channel under the guiding action of the guiding body 8. A first clearance channel 12 is arranged between the piston 5 and the inner ring of the shell 2, and the piston 5 can axially move in the first clearance channel 12; a second clearance channel 13 is arranged between the piston 5 and the piston 5. The cross-sectional area of the second clearance channel 13 is smaller than the cross-sectional area of the first clearance channel 12. The piston is characterized by further comprising a split retainer ring 4, wherein the piston 5 rod is sleeved with the split retainer ring 4, and the piston 5 rod is connected with the piston 5 through the split retainer ring 4. The split collar 4 is arranged such that the piston 5 does not fall off when the piston 5 is rod-connected.
At least one O-shaped sealing ring 7 is arranged between the guide body 8 and the shell 2. The O-ring 7 is provided to seal against leakage of the medium from between the housing 2 and the guide body 8.
At least one Y-shaped sealing ring 9 is arranged between the guide body 8 and the piston 5 rod. The Y-shaped sealing ring 9 can play a sealing role and prevent the medium from leaking between the guide body 8 and the piston 5 rod.
