Description
Technical field
The present invention relates to the outer locked cylinder of one.
Background technology
Currently used oil cylinder, when terminating use, being in recovery state, owing to not locking piston rod, lives
Stopper rod has the improper possibility stretched out, and easily causes accident, and safety is poor.
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 outer locked cylinder, it is at piston
It can be locked after reclaiming by bar, prevents it from improper stretching out, it is to avoid the generation of accident, improves safety.
For reaching above-mentioned purpose, a kind of outer locked cylinder of the present invention, including cylinder barrel, end cap, piston rod, piston, guiding
Set, rod chamber hydraulic fluid port and rodless cavity hydraulic fluid port；It is characterized in that being fixedly connected with hold-down support outside the cylinder barrel of fairlead side, fixing
Bearing front is arranged at intervals with parallel bearing, and several bolts are connected through parallel bearing with hold-down support, and parallel bearing is provided with confession
The centre bore that piston rod passes through, piston rod is provided with two shaft shoulders；One mounting seat is fixed on parallel bearing and hold-down support, mounting seat
The other end couples with ring flange, and the cylinder barrel of a locked cylinder is fixed on ring flange, and mounting seat and ring flange are equipped with through hole, lock
The piston rod of stand oil cylinder through mounting seat and ring flange and parallel bearing and hold-down support, the piston rod of locked cylinder
On be associated with plate, plate is provided with draw-in groove；
After piston rod reclaims, two shaft shoulders of piston rod, between parallel bearing and hold-down support, control the piston of locked cylinder
Bar is descending so that the draw-in groove of plate is stuck between two shaft shoulders, can lock piston rod, prevents it from improper stretching out, keeps away
Exempt from the generation of accident, improve safety.
As a further improvement on the present invention, it is equipped with positioning sleeve outside the bolt between parallel bearing and hold-down support；
Parallel bearing can axially be positioned by positioning sleeve, it is simple to realization be arranged in parallel with hold-down support；
As a further improvement on the present invention, described several bolt is positioned at piston rod both sides；The support to parallel bearing can be increased
Intensity, does not the most affect the stroke of plate.
In sum, it can be locked after piston rod reclaims by the present invention, prevents it from improper stretching out, it is to avoid thing
Therefore generation, improve safety.
