Embodiment
The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described
Embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, a kind of steel ball locking type hydraulic cylinder, including cylinder barrel 1, the piston 2 in cylinder barrel 1 and lead
It is arranged on the piston 2 simultaneously to set 3, the limit switch 4 on cylinder barrel 1 and the slide bar 5 slided up and down on cylinder barrel 1, guide sleeve 3
And be mutually slidably connected between the two, the one end of slide bar 5 stretches out in cylinder barrel 1 and is in contact with limit switch 4, and the other end stretches into cylinder barrel 1
Inside is in contact with guide sleeve 3, and piston 2 is provided with steel ball 6 and ball groove 7, and the movement of piston 2 contacts with guide sleeve 3 promotes guide sleeve 3
Moving, which moves up its band moving slide-bar 5, connects limit switch 4, and ball groove 7 is forced into by guide sleeve 3 after the contact guide sleeve 3 of steel ball 6
Interior, the return of guide sleeve 3 departs from slide bar 5 makes the downslide of slide bar 5 disconnect limit switch 4.
In addition, the end of guide sleeve 3 is provided with back-moving spring 8, the other end of back-moving spring 8 is connected on cylinder barrel 1, back-moving spring
8 promotion guide sleeves 3, which reset, makes guide sleeve 3 that steel ball 6 is pushed into ball groove 7.
In addition, the both ends of slide bar 5 are spherical, the contact surface of guide sleeve 3 and slide bar 5 is inclined-plane.
In addition, being provided with compression spring 9 between slide bar 5 and cylinder barrel 1, compression spring 9 is sheathed on slide bar 5, and one end is connected to
The other end is connected on cylinder barrel 1 on slide bar 5.
Promote piston 2 to move for rod chamber 10 and rodless cavity 11, the oil-feed of rodless cavity 11 in addition, piston 2 divides cylinder barrel 1, have
