Description
Technical field
It the utility model is related to gas spring technology field, more particularly to a kind of gas spring supporting rod.
Background technology
Gas spring supporting rod has been used widely in all trades and professions at present, its basic structure and design principle are：Gas
Spring is mainly by the piston in cylinder barrel, cylinder barrel, supporting rod, the guide sleeve for being connected on rod chamber cylinder barrel and being sleeved on supporting rod
Formed with sealing ring etc., high pressure nitrogen is filled with cylinder barrel, gas pressure intensity acts on the different side face of piston ring of sectional area, produces
A lateral pressure small to sectional area, as supports pressure.During work in supporting rod press-in cylinder barrel, but piston rod after long-term motion
There is abrasion with cylinder barrel surface, the chronic leakage be easy to causeing, and it is cumbersome lubricating grease is added after piston rod and cylinder barrel separation.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of gas spring supporting rod.
The utility model adopts the following technical solution：
A kind of gas spring supporting rod, including piston rod and cylinder barrel, the piston rod are equipped with guide sleeve, are set in the cylinder barrel
There is oil pocket, the cylinder barrel is equipped with sealing bolt, and the sealing bolt is connected through the guide sleeve and with the oil pocket, described
Oil filler point is offered on sealing bolt, the oil filler point is connected with the oil pocket, is equipped with shrapnel in the oil pocket, the shrapnel and
The piston rod offsets, and the shrapnel is equipped with through hole.
Preferably, the end of the cylinder barrel is equipped with damping cavity, and the other end of the damping cavity is equipped with end cap, on the end cap
Equipped with damping hole.
Preferably, the oil filler point is equipped with sealing-plug, and the sealing-plug is removably connected with the oil filler point.
Preferably, it is additionally provided with sealing shroud between the piston rod and the guide sleeve.
Preferably, the sealing shroud is made of polytetrafluoroethylene material.
The utility model has the advantages that:The utility model on gas spring supporting rod by setting oiling to fill
Put, may not need and dismantled piston rod and oil cylinder, add lubricating grease immediately, reduce the abrasion of piston rod and cylinder barrel.

Embodiment
As shown in Figure 1 to Figure 2, it is a kind of gas spring supporting rod of the utility model, including piston rod 1 and cylinder barrel 2, piston
Bar 1 is equipped with guide sleeve 3, and oil pocket 4 is equipped with cylinder barrel 2, and cylinder barrel 2 is equipped with sealing bolt 5, and sealing bolt 5 passes through guide sleeve 3 simultaneously
It is connected with oil pocket 4, oil filler point 6 is offered on sealing bolt 5, oil filler point 6 is connected with oil pocket 4, and shrapnel 7, shrapnel are equipped with oil pocket 4
7 offset with piston rod 1, and shrapnel 7 is equipped with through hole 8.Oil filler point 6 is equipped with sealing-plug 9, sealing-plug 9 removably with oil filler point 6
Connection.
The end of cylinder barrel 2 is equipped with damping cavity 10, and the other end of damping cavity 10 is equipped with end cap 11, and end cap 11 is equipped with damping hole
12, play the role of it is slow open, Slow Close, protection is overall without damage.
Sealing shroud 13 is additionally provided between piston rod 1 and guide sleeve 3, sealing shroud 13 is made of polytetrafluoroethylene material.
The operation principle of the utility model:
Sealing-plug 9 to be opened, lubricating grease is injected into oil pocket 4 from the oil filler point 6 on sealing bolt 5, rotates piston rod 1,
Since piston rod 1 and the shrapnel 7 in oil pocket 4 offset, when 1 extrusion elastic 7 of piston rod, shrapnel 7 squeezes lubricating grease by through hole 8
Enter onto piston rod 1, lubricating action can be played to piston rod 1, without piston rod 1 and cylinder barrel 2 are dismantled, reduce piston rod 1
With the abrasion of cylinder barrel 2.
The above are only specific embodiments of the present invention, but the technical characteristics of the utility model is not limited thereto.Appoint
How based on the utility model, to solve essentially identical technical problem, essentially identical technique effect is realized, it is made
Simple change, equivalent substitution or modification etc., are all covered by among the scope of protection of the utility model.
