Description
Technical field
The present invention relates to hydraulic cylinder technical field, specifically a kind of low voltage starting oil cylinder.
Background technology
Existing hydraulic cylinder includes cylinder barrel, by the guide sleeve in cylinder barrel, piston rod and cylinder barrel with piston
The cylinder head connected firmly, cylinder barrel is interior to be equipped with rod chamber hydraulic fluid port and rodless cavity hydraulic fluid port.
In order to reduce impact when piston rod is fallen after rise to cylinder barrel bottom, buffering is equipped between piston rod end and cylinder barrel bottom
Chamber.But this buffer structure the problem is that：In low pressure, piston rod end stress surface is smaller, and startup speed is slower, influences
Working efficiency.
Invention content
In order to solve the above technical problems, the present invention provides a kind of low voltage starting oil cylinder.
The invention is realized by the following technical scheme：A kind of low voltage starting oil cylinder, including the cylinder barrel of open at one end and installation
Piston rod in cylinder barrel；Cylinder barrel front end is connected with end cap；Centre bore is provided on the end cap, piston rod slides through end cap；
Piston rod inner end is connected with piston；The piston is slidably mounted in cylinder barrel；The cylinder barrel bottom is provided with cushion chamber, the piston rod
Inner end is equipped with the buffering protrusion coordinated with cushion chamber；The cylinder barrel bottom end is provided with the oil inlet being connected to cushion chamber bottom, cylinder barrel
Front end is provided with oil return opening；The cylinder barrel bottom starts oilhole there are one also opening；The startup oilhole inner end is opposite with piston inner face,
Start oilhole outer end and is connected through a screw thread check valve；The check valve and oil inlet are connected with oil inlet pipe jointly.
Preferably：Guide sleeve is equipped on the inside of the end cap；The guide sleeve outer wall is inlaid in cylinder barrel, guide sleeve sliding sleeve
Dress on the piston rod, sealing ring is equipped between guide sleeve inner wall and piston rod.
Preferably：Dustband is installed between the end cap inner wall and piston rod.
Preferably：Sealing ring is installed between the piston outer wall and cylinder barrel.
When piston rod is fallen after rise, check valve ends outward, and buffering protrusion, cushion chamber, which cooperate, completes buffering；Piston rod returns
Falling behind, when stretching out again, check valve is inwardly connected, and high pressure oil enters piston end surface by starting oilhole, expands the face of accepting,
Namely improve Pneumatic pressure.
Compared with prior art, the beneficial effects of the invention are as follows：Also easily start in low pressure, improves and start speed, in turn
Improve working efficiency.
Description of the drawings
Fig. 1 is structural schematic diagram of the invention.
In figure：1, cylinder barrel；1-1, cushion chamber；2, piston；3, end cap；4, piston rod；4-1, buffering protrusion；5, oil inlet；
6, oil return opening；7, start oilhole；8, check valve；9, oil inlet pipe；10, guide sleeve.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of low voltage starting oil cylinder, including the cylinder barrel 1 of open at one end and the piston rod in cylinder barrel 1
4；1 front end of cylinder barrel is connected with end cap 3；Centre bore is provided on the end cap 3, piston rod 4 slides through end cap 3；4 inner end of piston rod
It is connected with piston 2；The piston 2 is slidably mounted in cylinder barrel 1；3 inside of end cap is equipped with guide sleeve 10；10 outer wall of the guide sleeve
It is inlaid in cylinder barrel 1,10 sliding sleeve of guide sleeve is equipped with sealing on piston rod 4 between 10 inner wall of guide sleeve and piston rod 4
Circle.Dustband is installed between 3 inner wall of end cap and piston rod 4.Sealing ring is installed between 2 outer wall of the piston and cylinder barrel 1.
1 bottom of cylinder barrel is provided with cushion chamber 1-1, and 4 inner end of piston rod is equipped with the buffering protrusion 4-1 with cushion chamber 1-1 cooperations；Cylinder barrel
1 bottom end is provided with the oil inlet 5 being connected to the bottoms cushion chamber 1-1, and 1 front end of cylinder barrel is provided with oil return opening 6.
1 bottom of cylinder barrel starts oilhole 7 there are one also opening；It is opposite with 2 inner face of piston to start 7 inner end of oilhole, starts outside oilhole 7
End has been connected through a screw thread check valve 8；Check valve 8 and oil inlet 5 are connected with oil inlet pipe 9 jointly.
When piston rod is fallen after rise, check valve ends outward, and buffering protrusion, cushion chamber, which cooperate, completes buffering；Piston rod returns
Falling behind, when stretching out again, check valve is inwardly connected, and high pressure oil enters piston end surface by starting oilhole, expands the face of accepting,
Namely improve Pneumatic pressure.
