Description

A kind of oil cylinder
Technical field
The utility model relates to a kind of oil cylinder.
Background technique
Existing operation of oil cylinde is complicated, connects inconvenience, and volume is comparatively large, heavier-weight, once there is situation about stopping in working stroke, will cause the stressed decline of piston rod.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple to operate, easy to connect, reduces mounting point, reduction equipment volume, reduce weight, and stop in the middle of any working stroke, also can not cause the oil cylinder making the stressed decline of piston rod under external force.
For solving the problem, the utility model adopts following technological scheme:
A kind of oil cylinder, comprise earrings, hard tube, cylinder body and hydraulic lock, described earrings rear is connected to fastening screw nut, and described fastening screw nut rear is provided with stuffing box gland, and described hard tube and hydraulic lock are all equipped on cylinder body, described hard tube connects with hydraulic lock, described hard tube is connected with cylinder body by the handing-over bolt arranged with hydraulic lock, is provided with piston rod in described cylinder body, and described piston rod rear is connected to piston, described piston rear is connected to oil cylinder cover, and described earrings, cylinder body are connected successively with oil cylinder cover.
As preferably, described handing-over bolt is provided with two.
Working principle:
The hydraulic cylinder assembly assembled is connected hydraulic lock with hard tube, and utilizes selector valve connection hydraulic lock to make cylinder piston rod make fore and aft motion, make hydraulic lock not pin piston rod under oil condition as auxiliary member at selector valve.
The beneficial effects of the utility model are: simple to operate, easy to connect, and oil cylinder is stopped in the middle of any working stroke, also the stressed decline of piston rod can not be made under external force, and be used in industrial and mineral and mechanically reduce mounting point, reduction equipment volume, reduce weight.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil cylinder of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of oil cylinder, comprise earrings 1, hard tube 4, cylinder body 5 and hydraulic lock 6, described earrings 1 rear is connected to fastening screw nut 2, described fastening screw nut 2 rear is provided with stuffing box gland 3, described hard tube 4 is all equipped on cylinder body 5 with hydraulic lock 6, described hard tube 4 connects with hydraulic lock 6, described hard tube 4 is connected with cylinder body 5 by the handing-over bolt 7 arranged with hydraulic lock 6, piston rod 8 is provided with in described cylinder body 5, described piston rod 8 rear is connected to piston 9, and described piston 9 rear is connected to oil cylinder cover 10, and described earrings 1, cylinder body 5 are connected successively with oil cylinder cover 10.
Described handing-over bolt 7 is provided with two.
The beneficial effects of the utility model are: simple to operate, easy to connect, and oil cylinder is stopped in the middle of any working stroke, also the stressed decline of piston rod can not be made under external force, and be used in industrial and mineral and mechanically reduce mounting point, reduction equipment volume, reduce weight.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
