Abstract
The utility model relates to a kind of structure of air compressor piston, and guide ring and piston body cast or glue bond is integrated, and piston ring is compressed on the piston body by pressing plate, very close to each other, can not produce noise; Piston ring, guide ring do not have opening, and can seal completely, not have leakage during work, air displacement is larger than conventional construction, and efficiency improves too; Air is by casing, and through parts such as connecting rod, bearing, cranks, then by piston intake cylinder, form cold air convection, inflow noise reduces, and component rapid heat dissipation in casing and cylinder, improves bearing and piston ring life-span.
Description
Technical field
The utility model relates to a kind of air compressor technology, specifically a kind of structure of air compressor piston.
Background technique
The structure of current air compressor piston as shown in Figure 1, 2, mainly comprise piston body 2, piston body 3 sidepiece is provided with the annular groove 21 coordinated with guide ring 1 and piston ring 3, in order to guide ring 1 and piston ring 3 can facilitate in installing ring connected in star, this structure makes guide ring 1 and there is gap 5 between piston ring 3 and annular groove sidewall, runs and easily produces larger noise; In addition in order to make guide ring 1 and piston ring 3 be installed to smoothly in annular groove, guide ring 1 and piston ring 3 being all provided with opening 4, so just causing sealing not exclusively, having a small amount of gas leakage during work, cause air displacement to reduce; Moreover existing structure adopts cylinder cap air inlet, noise is large, and piston self does not have radiating structure, the heat-conducting property of piston ring and guide ring is very poor, heat cannot be passed to cylinder, can only pass to connecting rod by wrist pin and bearing, cause connecting rod bearing heating value large, the life-span is short.
Model utility content
The purpose of this utility model is the structure providing a kind of air compressor piston, guide ring and piston body cast or glue bond is integrated, piston ring is compressed on the piston body by pressing plate, very close to each other, can not produce noise, piston ring, guide ring do not have opening, can seal completely, do not have leakage during work, air displacement is larger than conventional construction, and efficiency improves too; Air is by casing, and through parts such as connecting rod, bearing, cranks, then by piston intake cylinder, form cold air convection, inflow noise reduces, and component rapid heat dissipation in casing and cylinder, improves bearing and piston ring life-span.
For achieving the above object by the following technical solutions:
A kind of structure of air compressor piston, comprise piston body, piston ring and guide ring is socketed in from top to bottom outside piston body, guide ring and piston body cast or glue bond is integrated, piston ring is compressed on the piston body by pressing plate, has screw at piston body top, has a pressing plate to be fastened on piston body top by plate screw, piston ring from top squeeze piston ring, and is fixed between piston body and pressing plate by pressing plate.
Described piston ring is bowl-shaped piston ring.
Described pressing plate has through hole and inlet hole, and piston body top is also provided with inlet hole, and have a valve block to arrange on pressing plate and closed by the inlet hole at pressing plate and piston body top, valve block screw is connected with pressing plate screw, and valve block is fixed on pressing plate.
The utility model guide ring and piston body cast or glue bond is integrated, and piston ring is compressed on the piston body by pressing plate, very close to each other, can not produce noise, not have leakage during work, efficiency improves, adopt the air inlet of piston body top, air needs by casing, through parts such as connecting rod, bearing, crank and piston bodies, then enters cylinder by piston body, form cold air convection, inflow noise reduces, and in casing and cylinder, the loose pad of component is fast, improves bearing and piston ring life-span.

Embodiment
As shown in Figure 3,4, a kind of structure of air compressor piston, comprise piston body 2, bowl-shaped piston ring 31 and guide ring 1 is socketed in from top to bottom outside piston body 2, guide ring 1 and piston body 2 cast or glue bond is integrated, and have screw 22, have a pressing plate 6 to be fastened on piston body 2 top by plate screw 9 at piston body 2 top, bowl-shaped piston ring 31 from top squeeze bowl-shaped piston ring 31, and is fixed between piston body 2 and pressing plate [S6] 6 by pressing plate 6; Described pressing plate 6 has through hole 61 and inlet hole 62, and piston body 2 top is also provided with inlet hole 62, has a valve block 9 to arrange on pressing plate 6 and by the inlet hole 62 of pressing plate 6 and closes, and valve block screw 8 is connected with pressing plate screw 63 and is fixed on pressing plate 6 by valve block 9.
The utility model guide ring 1 and piston body 2 cast or glue bond is integrated, pressing plate 6 and piston body 2 are spirally connected, bowl-shaped piston ring 31 is fixedly clamped from upper and lower both sides by piston body 2 and pressing plate 6, bowl-shaped piston ring 31, very close to each other between guide ring 1 and piston body 2, noise can not be produced, do not have leakage during work, efficiency improves.
This practical top inlet hole 62 being arranged piston body 2 on the other hand, piston body 2 inside forms one gas-entered passageway, during air inlet, air needs to pass through casing, through parts such as connecting rod, bearing, crank and piston bodies, enter cylinder by piston body again, form cold air convection, inflow noise reduces, component rapid heat dissipation in casing and cylinder, improves bearing and piston ring life-span.
