The multiformity of operating mode, the situation for occurring cylinder operation overload unavoidably, this is accomplished by designing overload protection, and the means of routine are logical
Cross and set up meter relief valve to gas supply part separately, so as to prevent cylinder continuation action in the case of an overload, but this method non-fully may be used
Lean on, main reason is that different cylinder load are different, and relief valve is generally adjusted by operator, once carelessness or regulation are not
When, however it remains the potential safety hazard of overload protection failure.For this purpose, needing to be improved existing cylinder.
The content of the invention
For overcoming above-mentioned deficiency, this utility model design one kind is from pressure release piston rod so as to solve existing cylinder overload anti-
The more single technical problem of the mode of shield.Which adopts the following technical scheme that realization.
One section should be axially arranged with from one end of pressure release piston rod connection piston, one end of piston rod connection piston along piston rod
Axial slide opening, axial slide opening open at one end, other end closing, and opening end is positioned at the piston rod end end face；The piston rod
The radial direction through hole communicated with the axial slide opening, and the radial direction through hole are radially provided near the blind end of the axial slide opening, institute
The opening end and the radial direction through hole of stating axial slide opening are located at the both sides of the piston respectively；Arrange axially in the axial slide opening
The slide block of slip, for being slidingly sealed between slide block and axial slide opening, and arranges abutting between the blind end of slide block and axial slide opening
Back-moving spring；The opening end limit screw cap of the threaded connection with axially extending bore of the axial slide opening, limit screw cap will be described
Slide block, back-moving spring are limited in the axial slide opening；Under the back-moving spring original state, the slide block is located at the axial direction
In the middle part of slide opening, the axially extending bore of the limit screw cap is not turned on the radial direction through hole of the piston rod；When the slide block is towards described
When axial slide opening blind end slides into positive stop end, the axially extending bore of the limit screw cap passes through the axial slide opening and the piston
The radial direction through hole conducting of bar.By said structure, when piston pressure side is transshipped, promoted in 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 the exhaust end of radial direction slide opening pressure release to piston opposite side, realize that cylinder, from decompression protection, more may be used
By convenient.
The axial slide opening is cylindrical hole, and the slide block is cylindrical traveller or ball.The structure is easy for installation, work compared with
For reliability.
The head cap part of the limit screw cap is located at the piston rod end face, and head cap part is elastic rubbery body, is played
Buffering and the effect of damping.
This utility model realizes cylinder from decompression function, coordinate existing supply part from pressure release, cylinder operation more may be used
By, safety.

Specific embodiment
In conjunction with accompanying drawing, this utility model is described as follows.
As shown in Figure 1 and Figure 2, should be from one end of pressure release piston rod connection piston 2, the end of piston rod 1 is along 1 axial direction of piston rod
One section of axial slide opening 101,101 open at one end of axial slide opening, other end closing is provided with, and opening end is located at the end end of piston rod 1
Face；The piston rod 1 is radially provided with the radial direction through hole 102 communicated with the axial slide opening 101, and the radial direction through hole 102 leans on
The blind end of the nearly axial slide opening 101, opening end and the radial direction through hole 102 of the axial slide opening 101 are located at institute respectively
State the both sides of piston 2.Slide block 3 in axial sliding are set in the axial slide opening 101, and slide block 3 is cylindrical traveller or ball, sliding
For being slidingly sealed between block 3 and axial slide opening 101, and the reset of abutting is set between the blind end of slide block 3 and axial slide opening 101
Spring 4.Axial slide opening 101 opening end threaded connection with axially extending bore 501 limit screw cap 5, 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
