Bar collided with, degree of impairment, at this time just needs that pull rod is repaired or replaced, the hydraulic oil in oil cylinder can be with pull rod
It splits out and flows out, hydraulic oil flows on machine and ground, will cause environmental pollution；Also it can increase safety to the operator of walking
Hidden danger；And Mode-locking oil cylinder hydraulic oil amount of storage is big, needs to buy hydraulic oil again after flowing away, waste financial resources.
Summary of the invention
It is provided a kind of easy-to-mount the technical problem to be solved by the present invention is to overcome the above-mentioned insufficient of the prior art
Mode-locking oil cylinder enables to prevent the hydraulic oil in Mode-locking oil cylinder from flowing out when its folding pull rod.
The present invention solves the above problems used technical solution are as follows: a kind of easy-to-mount Mode-locking oil cylinder, including front cover,
Pull rod, Mode-locking oil cylinder cylinder, Mode-locking oil cylinder rear cover, piston, locking gland, nut；The piston is placed in the cavity of Mode-locking oil cylinder cylinder
In, the front cover is fixed on Mode-locking oil cylinder cylinder front, and piston front inner ring is sealed and is slidably connected with front cover outer ring, and is formed
Preceding seal oil chamber；It the rear cover outer ring and Mode-locking oil cylinder cylinder rear seal and is slidably connected, piston rear portion outer ring and rear cover inner ring
It seals and is slidably connected, and seal oil chamber after formation；The pull rod passes through front cover, piston, and pull rod middle part is drawn by piston limit
Bar tail portion is connect with piston thread, and is compressed by locking gland, and locking gland is fixed on piston.
Preferably, above-mentioned pull rod is also set up to its internal rounded corner.
Preferably, above-mentioned front cover is fixed on Mode-locking oil cylinder cylinder by step.
Preferably, limited step is arranged in postoperculum after above-mentioned Mode-locking oil cylinder, prevents postoperculum after Mode-locking oil cylinder from entering mode locking
In cylinder tube.
Preferably, it is limited in the middle part of above-mentioned pull rod by step.
Preferably, above-mentioned locking gland is fixed in the threaded securing bores of piston by screw.
Compared with the prior art, the advantages of the present invention are as follows: when Mode-locking oil cylinder maintenance or replacement pull rod, it need to only open end
Lid splits out gland, screws out nut, can extract pull rod out, and front cover, piston, rear cover, Mode-locking oil cylinder cylinder need not tamper at this time,
Therefore convenient for disassembly and assembly, hydraulic fluid leak will not especially occur, it is free from environmental pollution, safety guarantee, and energy are brought to maintenance personal
Saving fund.
Detailed description of the invention
Fig. 1 is the overall structure diagram of existing Mode-locking oil cylinder.
Fig. 2 is a kind of structural schematic diagram of easy-to-mount Mode-locking oil cylinder of the embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawing, the present invention will be further described for embodiment.
As shown in Fig. 2, a kind of easy-to-mount Mode-locking oil cylinder, including front cover 4, pull rod 5, Mode-locking oil cylinder cylinder 1, Mode-locking oil cylinder
Rear cover 8, piston 2, locking gland 7, nut 6, Mode-locking oil cylinder rear cover 3.
Above-mentioned front cover 4 is connected to 1 front of Mode-locking oil cylinder cylinder, and 4 front of front cover is protruded into 1 cylinder of Mode-locking oil cylinder cylinder, after front cover 4
Step 45 is arranged in portion, cooperates with the step 15 of 1 front end of Mode-locking oil cylinder cylinder, and be fixed on end stand before Mode-locking oil cylinder cylinder 1 by screw 9
On rank 15.
Above-mentioned Mode-locking oil cylinder rear cover 3 is fixed on 1 rear end of Mode-locking oil cylinder cylinder, and after being fixed on Mode-locking oil cylinder cylinder 1 with screw 9
On end.
Above-mentioned piston 2 is placed in 1 inner cavity of Mode-locking oil cylinder cylinder, and 2 front inner ring 21 of piston is sealed with 4 outer ring 41 of front cover, and by
Sealing ring 43 seals.
Above-mentioned rear cover 8 is fixed on the piston 2 with screw 10, and 8 inner ring 81 of rear cover is sealed with outer ring 23 after piston 2, outside rear cover 8
Circle 82 is sealed with 1 inner wall of Mode-locking oil cylinder cylinder sealing ring 83.
