Description
Technical field
The present invention relates to cylinder, be in a kind of actuating cylinder from pressure release piston rod.
Background technology
General actuating cylinder is made up of structures such as cylinder barrel, piston, piston rods, controls inlet and outlet by cylinder barrel two ends, thus
Promoting piston to move back and forth along cylinder barrel is internal, stretching motion is made in the output of piston driving piston rod.In actual applications, due to work
The multiformity of operating mode, occurs the situation that cylinder operation is transshipped unavoidably, and this is accomplished by designing overload protection, and the means of routine are logical
Cross and gas supply part is set up separately meter relief valve, thus prevent cylinder from continuing action in the case of an overload, but this method non-fully may be used
Lean on, main reason is that different cylinder load is different, and relief valve is generally regulated by operator, once neglects or regulates not
When, however it remains the potential safety hazard that overload protection lost efficacy.To this end, need existing cylinder is improved.
Summary of the invention
For overcoming above-mentioned deficiency, the present invention designs a kind of from pressure release piston rod so that it is solve existing cylinder overload prevention
The technical problem that mode is the most single.It adopts the following technical scheme that realization.
Should connect piston from one end of pressure release piston rod, piston rod connects one end of piston and is axially arranged with one section along piston rod
Axially slide opening, axial slide opening open at one end, the other end is closed, and opening end is positioned at this end end face of piston rod；Described piston rod
It is radially provided with the radial direction through hole communicated with described axial slide opening, and this radial direction through hole is near the blind end of described axial slide opening, institute
State the opening end of axial slide opening and described radial direction through hole and lay respectively at the both sides of described piston；Arrange in described axial slide opening axially
The slide block slided, for slipper seal between slide block and axially slide opening, and arranges between slide block and the blind end of axial slide opening and pushes against
Back-moving spring；The threaded limit screw cap with axially extending bore of opening end of described axial slide opening, limit screw cap is by described
Slide block, back-moving spring are limited in described axial slide opening；Under described back-moving spring original state, described slide block be positioned at described axially
In the middle part of slide opening, the axially extending bore of described limit screw cap does not turns on the radial direction through hole of described piston rod；When described slide block is towards described
When axially slide opening blind end slides into positive stop end, the axially extending bore of described limit screw cap is by described axial slide opening and described piston
The radial direction through hole conducting of bar.By said structure, when piston pressure side overload, in promoting axial slide opening by overload pressure
Slide block slide into positive stop end towards the direction of compression reseting spring so that overload pressure by the axially extending bore of limit screw cap,
The axial slide opening of piston rod and radially slide opening pressure release are to the exhaust end of piston opposite side, it is achieved cylinder, from decompression protection, more may be used
By convenient.
Described axial slide opening is cylindrical hole, and described slide block is cylindrical traveller or ball.This structure is easy for installation, and work is relatively
For reliably.
The head cap part of described limit screw cap is positioned at described piston rod end face, and head cap part is elastic rubbery body, plays
Buffering and the effect of damping.
The present invention realizes cylinder from decompression function, coordinate existing supply part from pressure release, cylinder operation is the most reliable, peace
Entirely.

Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described as follows.
As shown in Figure 1 and Figure 2, should connect piston 2 from one end of pressure release piston rod, this end of piston rod 1 is axial along piston rod 1
Being provided with one section of axial slide opening 101, axial slide opening 101 open at one end, the other end is closed, and opening end is positioned at this end end of piston rod 1
Face；Described piston rod 1 be radially provided with the radial direction through hole 102 communicated with described axial slide opening 101, and this radial direction through hole 102 leans on
The blind end of nearly described axial slide opening 101, the opening end of described axial slide opening 101 and described radial direction through hole 102 lay respectively at institute
State the both sides of piston 2.Arranging slide block 3 in axial sliding in described axial slide opening 101, slide block 3 is cylindrical traveller or ball, sliding
For slipper seal between block 3 and axially slide opening 101, and between the blind end of slide block 3 and axial slide opening 101, the reset pushed against is set
Spring 4.The axially threaded limit screw cap 5 with axially extending bore 501 of opening end of slide opening 101, limit screw cap 5 by slide block 3,
Back-moving spring 4 is limited in axial slide opening 101, and the axially extending bore 501 of limit screw cap 5 is by axial slide opening 101 and piston rod 1
Axially slide opening 101 opening end turned on outside.Under back-moving spring 4 original state, slide block 3 is positioned in the middle part of axial slide opening 101, spacing spiral shell
The axially extending bore 501 of cap 5 does not turns on the radial direction through hole 102 of piston rod 1；When slide block 3 slides into towards axial slide opening 101 blind end
During positive stop end, back-moving spring 4 is compressed, and the axially extending bore 501 of limit screw cap 5 passes through axial slide opening 101 and the piston of piston rod 1
The radial direction through hole 102 of bar 1 turns on.
In order to improve, piston rod 1 being crossed the protection slided in position, the head cap part of limit screw cap 5 is elastic rubbery body, and position
In piston rod 1 end face.
The operation principle of the present invention is: when be positioned in cylinder barrel piston 2 press side chamber overload time, transship chamber
Pressure promote slide block 3 compression reseting spring 4 in axial slide opening 101 and slide into positive stop end, now, the axle of limit screw cap 5
Turned on by the radial direction through hole 102 of the axial slide opening 101 of piston rod 1 with piston rod 1 to through hole 501, the pressure pressure release of overload chamber
Exhaust chamber to cylinder barrel, it is achieved from decompression protection.When recovering to normal pressure, slide block 3 is under back-moving spring 4 acts on
Resetting, cylinder recovers normal work.
