Hold piston rod tightly, to arrive the purpose of locking；But existing tapered sleeve is not in axially location, easy squeezed briquetting drives and is axially moving
Dynamic, when causing unlocking, crushing block is not completely separated with tapered sleeve, the susceptiveness that impact unlocks, and impact is normal to be used.
Summary of the invention
It is an object of the invention to for deficiencies of the prior art, it is provided that a kind of locking cylinder, it has unblock
The advantage that susceptiveness is good, be easily installed, it is ensured that the normal use of oil cylinder.
For reaching above-mentioned purpose, a kind of locking cylinder of the present invention, including cylinder barrel, end cap, piston rod, piston, fairlead,
Rod chamber hydraulic fluid port and rodless cavity hydraulic fluid port；It is characterized in that the front end of fairlead is positioned at outside cylinder barrel, the front end of fairlead is associated with locking
Cylinder cylinder barrel, the locking cylinder cylinder barrel other end is associated with cylinder bottom, piston rod slide through cylinder bottom, before the fairlead in locking cylinder cylinder barrel
End is associated with plural cone block, and cone block is equipped with pre-small post-large male cone (strobilus masculinus) and inner arc surface, and all cone blocks are placed on piston rod
Outward, tapered sleeve is formed；Being sequentially provided with latching ram and reseting elastic element in the locking cylinder cylinder barrel in cone block front, latching ram sets
There is the inner conical surface matched with cone block male cone (strobilus masculinus), the locking cylinder cylinder barrel on rear side of latching ram is provided with unblock hydraulic fluid port；
During use, reseting elastic element promotes latching ram, latching ram inwardly to extrude each cone block to hold piston rod tightly, to arrive
The purpose of locking；During unblock, it is passed through hydraulic oil by unlocking hydraulic fluid port, promotes latching ram to move forward, latching ram and each cone block
Separate, it is achieved unlock；Due to the fact that each cone block is coupled to fairlead front end, the adhesive force of the piston that will not be locked etc. drives and does axle
To movement, have and unlock the advantage that susceptiveness is good, it is ensured that the normal use of oil cylinder.
As a further improvement on the present invention, described cone block is provided with T-slot radially, and fairlead front end is associated with two or more
Locating piece, the cross section of locating piece is T-shaped, cone block be placed on respective locating piece by its T-slot；It is fixed that this structure cone block is stuck in
On the block of position, it is simple to install；
As a further improvement on the present invention, described reseting elastic element is butterfly spring；Can apply axially, bigger elasticity
Power；
As a further improvement on the present invention, on the inner arc surface of cone block, all heaps are welded with layers of copper；Friction can be increased, apply bigger
Coupling mechanism force.
In sum, the present invention has and unlocks that susceptiveness is good, the advantage that is easily installed, it is ensured that the normal use of oil cylinder.

Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, a kind of locking cylinder of the embodiment of the present invention, including cylinder barrel 1, end cap 2, piston rod 3, live
Plug 4, fairlead 5, rod chamber hydraulic fluid port 6 and rodless cavity hydraulic fluid port 7；The front end of fairlead 5 is positioned at outside cylinder barrel 1, and the front end of fairlead leads to
Crossing screw thread and be associated with locking cylinder cylinder barrel 8, locking cylinder cylinder barrel 8 other end is associated with cylinder bottom 9, piston rod 3 slide through cylinder bottom 9, at lock
Fairlead front end in tight cylinder cylinder barrel 8 is associated with three locating pieces 10 by screw, and the cross section of three locating pieces 10 is T-shaped and is justifying
On week uniform, three cone blocks 11 are placed on respective locating piece 10 by its T-slot 12, cone block 11 be equipped with pre-small post-large outside
The conical surface and inner arc surface, on the inner arc surface of cone block 11, all heaps are welded with layers of copper 13, and all cone blocks 11 are placed on outside piston rod 3, shape
Become tapered sleeve；Being sequentially provided with latching ram 14 and butterfly spring 15 in the locking cylinder cylinder barrel 8 in cone block 11 front, latching ram 14 sets
