Description
Technical field
It the utility model is related to lubrication pump part, more particularly to a kind of pump core component for electronic lubricating pump.
Background technology
Electronic lubricating pump, which is concentrated, to be used in lubricating system, to equipment feed lubricant grease, generally meets metallurgy, mine, electricity
Abrasion in the various equipment of the industries such as power etc. needs.Existing electronic lubricating pump generally comprises the pump housing, motor and pump core, pump core bag
Pump core body, plunger and back-moving spring are included, plunger moves back and forth under motor driving and action of reset spring, holds seal operation
The volume of chamber changes to realize oil suction, force feed.However, back-moving spring is there is the risk of fatigue damage, and easily produce
Raw noise is simultaneously stuck, makes pump core can not normal work.
It is therefore desirable to a kind of pump core component for electronic lubricating pump, reduce by spring band Lai easily stuck wind
Danger, it is more stable efficient in reset function, extend the service life of pump core.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of pump core component for electronic lubricating pump, reduces
By spring band Lai easily stuck risk, in reset function it is more stable efficiently, extend the service life of pump core.
Pump core component of the present utility model for electronic lubricating pump, for the pump core component of electronic lubricating pump, including pump
Core body and the plunger being axially movable in pump core body is located at, in addition to for being fixed on the eccentric shaft of motor output end, institute
Eccentric shaft is stated by an axle sleeve with plunger to be connected；The axle sleeve with the rotation of eccentric shaft and along the radial reciprocating-oscillation of eccentric shaft,
So that axial reciprocating of the plunger along pump core body moves.
Further, the axle sleeve is set in outside eccentric shaft in a manner of gap coordinates.
Further, the bottom of the axle sleeve radially extends to form transverse slat, and outer end of the transverse slat away from axle sleeve is vertically
Extension forms stringer board, and linkage groove is formed between the stringer board and axle sleeve；Outer end of the plunger away from pump core body is caught in linkage
The linkage of plunger and axle sleeve is realized in groove.
Further, the outer end of the plunger is provided with a plush copper radially extended.
Further, the bottom of the axle sleeve radially extends the loading plate to be formed for carrying axle sleeve.
The beneficial effects of the utility model：
Pump core component of the present utility model for electronic lubricating pump, when in use, electrical power drive eccentric shaft rotation,
Axle sleeve is with the rotation of eccentric shaft and along the radial reciprocating-oscillation of eccentric shaft so that and axial reciprocating of the plunger along pump core body moves,
Therefore without using spring i.e. can reach reset effect, reduce by spring band Lai easily stuck risk, in reset function
It is more stable efficient, extend the service life of pump core.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model.
Embodiment
Fig. 1 is structural representation of the present utility model, and Fig. 2 is use state figure of the present utility model, as shown in the figure：This reality
The pump core component for electronic lubricating pump of example is applied, for the pump core component of electronic lubricating pump, including pump core body 4 and is located at pump
The plunger 3 being axially movable in core body 4, in addition to for being fixed on the eccentric shaft 1 of the output end of motor 5, the eccentric shaft 1 leads to
An axle sleeve 2 is crossed with plunger 3 to be connected；The axle sleeve 2 is with the rotation of eccentric shaft 1 and along the radial reciprocating-oscillation of eccentric shaft 1 so that post
Plug 3 moves along the axial reciprocating of pump core body 4；When in use, electrical power drives eccentric shaft 1 to rotate, and axle sleeve 2 is with eccentric shaft 1
Rotation and along the radial reciprocating-oscillation of eccentric shaft 1 so that axial reciprocating of the plunger 3 along pump core body 4 moves, therefore without making
Reset effect is can reach with spring, reduces the easily stuck risk come by spring band, it is more stable efficient in reset function,
Extend the service life of pump core.
In the present embodiment, the axle sleeve 2 is set in outside eccentric shaft 1 in a manner of gap coordinates；Gap can be 0.5mm-
2mm so that axle sleeve 2 is relatively isolated with eccentric shaft 1, and axle sleeve 2 will not be rotated and rotated with eccentric shaft 1, but the bias of eccentric shaft 1
Rotation can promote the reciprocally swinging of axle sleeve 2 (being to swing in figure).
In the present embodiment, the bottom of the axle sleeve 2 radially extends to form transverse slat, outer end of the transverse slat away from axle sleeve 2
Axially extend to form stringer board, linkage groove is formed between the stringer board and axle sleeve 2；The outer end of the plunger 3 away from pump core body 4
It is caught in linkage groove and realizes the linkage of plunger 3 and axle sleeve 2；The structure is easy to implement the linkage of plunger 3 and axle sleeve 2；In use,
Axle sleeve 2 forms thrust to plunger 3, and linkage groove forms pulling force effect to plunger 3, is achieved in moving back and forth for plunger 3；Together
When, the outer end of the plunger 3 is provided with a plush copper radially extended, and plush copper is preferably curved.
In the present embodiment, the bottom of the axle sleeve 2 radially extends the loading plate to be formed for carrying axle sleeve 2, to prevent
Axle sleeve 2 moves down.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
