Description
Technical field
The utility model relates to piston technical field, refers to that a kind of air compressor is without oily piston especially.
Background technique
Existing part air compressor adopts oily piston, and during piston rod movement, friction temperature is high; Prolonged exercise, the lubricant oil in piston is burned condensation, does not have lubrication, thus the wearing and tearing of aggravation piston rod; Increase the gap between piston rod and each component, poor sealing performance, shorten the working life of piston.In order to solve this technical barrier, prior art proposes without oily piston, and piston face is provided with a polytetrafluoroethylene floor; But prior art sliding capability is relatively poor, after a long time use, there will be wearing and tearing, sealing is poor.The quality of piston performance depends on sealing.
Model utility content
The utility model proposes a kind of air compressor without oily piston, solving occurs wearing and tearing after piston in prior art uses for a long time causes the problem of sealing difference.
The technical solution of the utility model is achieved in that a kind of air compressor is without oily piston, comprises piston rod, piston sleeve and piston ring; Described piston sleeve overlaps on the piston rod and its end face is provided with draw-in groove, and described piston ring is stuck in draw-in groove; Described piston sleeve is provided with polytetrafluoroethylene floor on the surface; Described piston ring comprises be tightly connected end and the right side, a left side and to be tightly connected end;
The described left side end that is tightly connected comprises left front sealed department and left back sealed department, and described left front sealed department is provided with left front sealing block, and described left front sealing block is crossing with left back sealed department and be provided with left front seal groove above left front sealing block;
The described right side end that is tightly connected comprises right front sealed department and right back seal groove, and described right front sealed department is provided with and can seals with left front seal groove the right front sealing block suited; The below of described right front sealing block is provided with the right front seal groove sealing with left front sealing block and suit; Described right back seal groove is connected with left back sealed department is salable.
Left front sealing block and right front seal groove are tightly connected as the first sealing layer; Right front sealing block and left front seal groove are tightly connected as the second sealing layer; Right back seal groove is connected with left back both seals as the 3rd sealing layer; Wherein, the 3rd sealing layer staggers with the first sealing layer and the second sealing layer respectively and arranges, and not easily allows air go out from connecting sewing; The utility model designs three-layer sealed structure, makes piston reach better sealing effect; The performance of further raising air compressor.
Further preferably, the termination of described left front sealing block and the termination of described right front sealing block are all arced terminus.
Further preferably, described left front seal groove is respectively equipped with on described right front seal groove the curve bath suited mutually with described arced terminus.
Further preferably, described piston sleeve is provided with pin-and-hole.
Further preferably, described piston sleeve is connected with described piston rod pin.
Compared with prior art, the beneficial effect that possesses of the utility model is as follows:
The utility model adopts without oil type piston, and structure is simple, and easy to use, practical, processing cost is low, lightweight, good sealing effect; Enhance the wear-resisting property of piston rod, extend the working life of piston, be easy to apply.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
