Abstract
The utility model discloses an assembled piston frame, include piston frame base of making by the metal and the piston head of making by plastics. The utility model discloses a piston frame base of being made by the metal and the piston head of being made by plastics, its advantage lie in that the piston frame base of metal material can improve the intensity of piston frame, and the deformations problems that moulds plastics, and the piston head of plastics material can reduce thermal transmission, reduces high -speed fricative damage to improve the diaphragm life -span, simple structure.
Description
Technical field
This utility model belongs to barrier film pump technical field, is particularly used for the diaphragm pump piston frame structure on water purifier.
Background technology
The piston shelf being used on membrane pump in the market is broadly divided into two kinds, and a kind of is entirely plastic material molding, this
Kind piston shelf is not high due to the intensity of plastics, and therefore piston shelf is easy to deform upon in use, and working of plastics is originally
Will deform in during injection；Another kind is all by metal material molding, this piston shelf have the shortcomings that one larger,
, because permanent load high speed operation can produce substantial amounts of heat, heat once passes to piston for motor below piston shelf and bearing
On frame, piston shelf will be with diaphragm high-speed friction at high temperature, and the service life of such diaphragm will substantially reduce.
Content of the invention
For deficiency of the prior art, this utility model provides a kind of piston shelf.
This utility model is achieved through the following technical solutions.A kind of assembled piston shelf, including the piston being made of metal
Frame pedestal and the piston head being made of plastics.
As the optimization further of technique scheme, described piston shelf pedestal is provided with mounting seat, in described mounting seat
It is provided with stopper slot, described piston head is provided with the limited block with stopper slot cooperation.
As the optimization further of technique scheme, the inner hollow of described limited block.
Compared with prior art, this utility model includes the piston shelf pedestal being made of metal and the piston being made of plastics
Head, it is advantageous that the piston shelf pedestal of metal material can improve the intensity of piston shelf, and injection molding deformation problem, plastic material
Piston head can reduce the transmission of heat, reduce the damage of high-speed friction, to improve the diaphragm life-span, structure is simple.
Brief description
Fig. 1 is the structural representation that this utility model lacks a piston head.
Fig. 2 is the structural representation of this utility model piston head.
Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, this utility model is further described.As depicted in figs. 1 and 2, one
Plant assembling piston shelf, including the piston shelf pedestal 1 being made of metal and the piston head 2 being made of plastics, described piston shelf pedestal 1
It is provided with three mounting seats 3, described piston head 2 is contained in described mounting seat 3, and described mounting seat 3 is provided with stopper slot 4, described
Piston head 2 is provided with the limited block 5 with stopper slot 4 cooperation, and when piston head 2 is attached in mounting seat 3, limited block 5 embeds spacing
In groove 4, prevent piston head 2 from deflecting in the course of the work.
In technique scheme, the inner hollow of described limited block 5, save manufacture material in the case of not affecting to use
Material.
This utility model for the piston shelf that all-metal is made, due to mould processing technology relation, plastic surface
Can process relatively smooth so that the piston head that plastics are made can reduce the abrasion to the diaphragm setting above it, extend
The service life of diaphragm, the heat conductivity of plastics is poor simultaneously, it is possible to reduce the heat that the motor below piston shelf sends at work
Amount is delivered on the diaphragm above piston shelf, extends the service life of diaphragm further；The piston shelf made with respect to all-plastic
For, the piston shelf pedestal that metal is made：On the one hand improve the bulk strength of piston shelf so that it is to be not susceptible in work
Deformation, extends the service life of piston shelf, the deformation in molding is less with respect to working of plastics for another aspect metalwork, more and be beneficial to
The concordance of product.
