Description
【Technical field】
It the utility model is related to piston manufacturing techniques field, more particularly to a kind of elastic piston structure for the pump housing.
【Background technology】
The piston of pump is that one kind enables valve to open and close against up and down motion, and in the motion process time control of piston
The switch of valve processed, opens content and then the discharge of the inside cavity made, sucks the content of containment portion during closing, by
Require high in air-tightness, but must have activity again, thus be exactly on this part requirements it is higher, typically using material
For rubber/silica gel or be plastic cement PE/PP, rubber and silica gel elastic splendid but production cost is too high, and PE/PP elasticity
Bad, injection machine production cost is relatively low, but size requires very strict again, so production efficiency is not high, but current city
Piston on face can not be accepted or rejected reasonably between, be that this technically has one to manufacture a kind of excellent piston
Fixed limitation.
【Utility model content】
Main purpose of the present utility model is to provide a kind of elastic piston structure for the pump housing, can effectively solve to carry on the back
The problem of in scape technology.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of elastic piston structure for the pump housing, including the pump housing and hydraulic cylinder, the bottom of the pump housing are provided with expects pipe mouth,
The intraoral interlocking of expects pipe has valve, and the inside of the pump housing is provided with plunger shaft, and the bottom of the hydraulic cylinder is provided with upperpush rod,
The piston cavity inner sleeve is connected to piston, and piston rod is connected with the middle part of the piston, and the center bottom of the hydraulic cylinder is provided with
Projection, formed with hydraulic cavities between the upperpush rod and piston.
Further, the projection is rectangular configuration, and the projection is right against piston rod.
Further, the material of the piston is PE plastic cement.
Further, the material of the piston is rubber.
Further, it is symmetrical relative to piston rod between the piston.
Further, the top of the plunger shaft is column structure, and the bottom of the plunger shaft is cone structure, the work
The top of plug chamber is provided with via and coordinates upperpush rod.
Further, the hydraulic cavities are sealing structure.
Compared with prior art, the utility model has the advantages that：This kind of utility model is reasonable in design, user
Just, by it is reasonable while use piston made of PE plastic cement and rubber so that piston is more flexible, to reach product in group
The requirement mixed, can compare the requirement loosened to size, and piston becomes more resistant against the type that is not easy in by temperature test, possessed
The characteristic of elastic material, also making to be not easy to allow product to be damaged in production so that the piston of manufacture has improving production efficiency, into
This decline, coordinate specification the advantages of relaxing, the competitiveness of product is improved in certain degree, practicality is higher, just
In popularization.
【Brief description of the drawings】
