Description
Technical field
The utility model is related to a kind of cylinder, is specifically a kind of cut-out air cylinder structure.
Background technology
Cylinder is the cylindrical metal parts for guiding piston to carry out straight reciprocating motion in cylinder.Air is in cylinder
In by expansion convert heat into mechanical energy；Gas receiving piston in compresser cylinder compresses and improves pressure.Turbine,
The housing of rotary engine etc. is generally also referred to as " cylinder ".The application field of cylinder：Printing（Tension force）, semiconductor
（Mash welder, chip grinding）, Automated condtrol, robot etc..
The situation for cutting off cylinder operationally stress is very complicated, except the pressure differential by gas inside and outside cylinder and is installed therein
The dead load such as the weight of each parts outside, to the reaction force of stationary part when still suffering from steam outflow stator blade, and respectively
Plant the active force to cylinder under connecting pipe cold-hot condition.The feelings that existing cut-out cylinder is revealed in conventional piston packing
Under condition, it is impossible to pressurize, so as to cause the limitation of power output.
Utility model content
The purpose of this utility model is to provide a kind of cut-out air cylinder structure, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：
One kind cut-out air cylinder structure, including cylinder body, the cylinder interior are provided with piston, and piston centre position offers logical
Hole, piston-rod lower end is through the through hole and is fixedly connected with the piston；Protecgulum is provided with above cylinder body, protecgulum is fixed with cylinder body to be connected
Connect；Protecgulum centre position offers through hole, and the through hole is stretched out in piston rod upper end；Set between piston outer wall lower end and inboard wall of cylinder block
There is piston packing, supporting part is provided between piston outer wall upper end and cylinder body；Piston upper surface is provided with end-face seal ring.
It is used as further program of the utility model：The material of the end-face seal ring is NBR rubber or fluorubber.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, reasonable in design,
On the basis of conventional cut-out cylinder, end-face seal ring is additionally arranged, one layer of sealing protection is added, compensate for conventional piston packing
Leakage can not pressurize situation, so as to solve the limitation of power output.It need to only be improved on the original basis, not shadow
Ring and install, can completely be replaced with existing structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- cylinder bodies, 2- piston packings, 3- supporting parts, 4- pistons, 5- end-face seal rings, 6- protecgulums, 7- pistons
Bar.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, a kind of cut-out air cylinder structure, including cylinder body 1, the inside of cylinder body 1 is provided with the middle of piston 4, piston 4
Position offers through hole, and the lower end of piston rod 7 is fixedly connected through the through hole and with piston 4；The top of cylinder body 1 is provided with protecgulum 6, preceding
Lid 6 is fixedly connected with cylinder body 1；The centre position of protecgulum 6 offers through hole, and the through hole is stretched out in the upper end of piston rod 7；The outer wall of piston 4
Piston packing 2 is provided between lower end and the inwall of cylinder body 1, supporting part 3 is provided between the outer wall upper end of piston 4 and cylinder body 1；Piston 4
Upper surface is provided with end-face seal ring 5.
Further, the material of end-face seal ring 5 described in the utility model is NBR rubber or fluorubber, with excellent
Heat resistance, inoxidizability, oil resistivity, corrosion resistance and resistance to weathering, with good sealing effectiveness, property is stable, makes
Use long lifespan.
The utility model compensate for the leakage of conventional piston packing can not pressurize situation, so as to solve the office of power output
It is sex-limited.It only need on the original basis be improved, not influence to install, can completely be replaced with existing structure.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
