In accompanying drawing, the list of parts representated by each label is as follows:
1, buffer head, 2, snap ring, 3, star sealing ring, 4, end cap, 5, lubricating cup, 6, piston rod, 7, stage clip, 8, hydraulic oil,
9, cam, 10, momentum adjusting screw rod, 11, sealing baffle, 12, sealing ring.
Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
As it is shown in figure 1, a kind of oil buffer for primary cut-out, including buffer head 1, lubricating cup 5, end cap 4, piston
Bar 6, hydraulic oil 8 and stage clip 7, lubricating cup 5 is vertically arranged, and end cap 4 seals the top open part being fixedly installed on lubricating cup 5, piston rod 6
Being vertically positioned in lubricating cup 5, its upper end is through end cap 4 and stretches out lubricating cup 5, and buffer head 1 is socketed in upper end and the piston of piston rod 6
The upper end of bar 6 is rotationally connected, and stage clip 7 is crimped between the lower end of piston rod 6 and lubricating cup 5, also includes momentum adjusting screw rod 10 He
Sealing baffle 11, sealing baffle 11 level slides in arranging lubricating cup 5 and is positioned at below stage clip 7, and hydraulic oil 8 is filled in lubricating cup 5
And it is positioned at the top of sealing baffle 11, in momentum adjusting screw rod 10 inserts lubricating cup 5 from lubricating cup 5 and be positioned at sealing baffle 11 times
Side, its one end inserted in lubricating cup 5 is fixedly connected with cam 9, and cam 9 offsets with sealing baffle 11, rotation impulse adjusting screw rod
