Description
Technical field
The utility model belongs to multi-functional pump core accessory field of mechanical technique, and in particular to a kind of multifunctional combination pump core.
Background technology
Pump core is the core component of pump, determines this pump performance and service life, is typically mounted in the pump housing, passes through leaf on axle
Wheel or blade drive water flowing, the axle that the less pump housing of some calibers is typically obliquely installed blade using band are corresponded to, for some
The pump of special occasions the pump housing is very long sometimes and caliber is often very narrow, can not now use impeller and with tiltedly setting blade
Often again not enough, therefore, it is necessary to multiple axles are assembled to complete work, and existing connection is generally by outside pump shaft for shaft length
To be fixed with screw rod, at work, failure of oscillation does not move pump shaft, rigidity assembling easily abrasion, and because pump shaft caliber is relatively thin in itself, it is corresponding
It is also smaller for fixed screw rod specification, cause disassembly and installation space small, it is not easy to operate, therefore, should be to its combination
It is further improved, avoids the problem of existing.
Utility model content
The purpose of this utility model is to be directed to existing issue, there is provided a kind of multifunctional combination pump core.
The utility model is achieved through the following technical solutions：A kind of multifunctional combination pump core, including at least two master
Axle, main shaft are provided with the blade slot being obliquely installed, blade are removably installed in blade slot, and connection is provided with main shaft both ends
Portion, connecting portion be connected end or coupling piece；
Wherein, the connecting portion includes cylinder groove and flower pattern groove；
The coupling piece both ends are provided with the flower pattern boss to match with flower pattern groove, and flower pattern boss includes arc convex, adjacent
Corresponding coupling piece is provided with groove between arc convex；The groove bottom is rectangular configuration, top be with rectangular configuration and
The arcuate structure that coupling piece periphery smoothly connects, groove bottom are fixed with elastomer, and elastomer is provided with and groove length phase
Same cylinder, the diameter of the cylinder are more than groove upper opening width；
Cylindrical magnetite is fixed with the coupling piece center.
As further improvement of these options, the side that the fixing end is connected with main shaft is provided with flower pattern boss, interior
Portion is provided with cylindrical magnetite.
As further improvement of these options, the connecting portion of the wherein side is conventional structure, corresponding fixed
Hold as conventional matched structure.
As further improvement of these options, the elastomer is that the groups of springs that is radially arranged or resilience are preferable
Cushion.
As further improvement of these options, the agent structure of the shaft coupling and the cylinder groove phase of connecting portion
Match somebody with somebody.
The utility model has advantages below compared with prior art：The multiple main shaft can be connected by coupling piece, due to
Cylindrical magnetic masonry inside coupling piece is used, and can ensure that coupling piece is fixedly connected with main shaft；Flower pattern boss can make the master of connection
Axle synchronous axial system；The mating reaction of cylinder and elastomer, the connecting portion cylinder groove that can aid in coupling piece and main shaft are further
It is fixed, while it also avoid due to the generation of mismatch case after vibration abrasion；Overall structure advantages of simple, can effectively will be more
Individual main shaft connection, coupling piece have the compactness that certain abrasion also can guarantee that its shaft coupling and connecting portion in vibration processes.

Fig. 2 is main axle structure schematic diagram.
Fig. 3 is connecting-piece structure schematic diagram.
Fig. 4 is connector side view.
Fig. 5 is fixing end structural representation.
Fig. 6 is the main axle structure schematic diagram for including conventional connecting portion.
Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in fig. 1, a kind of multifunctional combination pump core, including at least two main shaft 1, main shaft 1 are provided with what is be obliquely installed
Blade slot 11, dismountable installation blade 12, is provided with connecting portion 2, connecting portion 2 connects at the both ends of main shaft 1 in blade slot 11
Fixing end 3 or coupling piece 4；
Wherein, the connecting portion 2 includes cylinder groove 21 and flower pattern groove 22；
The both ends of coupling piece 4 are provided with the flower pattern boss 42 to match with flower pattern groove 22, and it is convex that flower pattern boss 42 includes arc
43 are played, corresponding coupling piece 4 is provided with groove between adjacent arc convex 43；The groove bottom is rectangular configuration 44, top
For the arcuate structure 45 smoothly to connect with rectangular configuration 44 and the periphery of coupling piece 4, groove bottom is fixed with elastomer 46, elasticity
Body 46 is provided with is more than groove upper opening width with groove length identical cylinder 41, the diameter of the cylinder 41；
Cylindrical magnetite 47 is fixed with the center of coupling piece 4.
As further improvement of these options, the side that the fixing end 3 is connected with main shaft 1 is provided with flower pattern boss
42, inside is provided with cylindrical magnetite 47.
As further improvement of these options, the connecting portion 2 ' of the wherein side is conventional structure, corresponding solid
Fixed end 3 is conventional matched structure.
As further improvement of these options, the elastomer 46 is preferable for the groups of springs or resilience being radially arranged
Cushion.
As further improvement of these options, the agent structure of the shaft coupling 4 and the phase of cylinder groove 21 of connecting portion 2
Matching.
The multiple main shaft 1 can be connected by coupling piece 4, can because the cylindrical magnetite 47 inside coupling piece 4 acts on
Ensure that coupling piece 4 is fixedly connected with main shaft 1；Flower pattern boss 42 can make the synchronous axial system of main shaft 1 of connection；Cylinder 41 and elastomer 46
Mating reaction, the connecting portion cylinder groove 21 that can aid in coupling piece 4 and main shaft 1 further fixes, at the same it also avoid by
The generation of mismatch case after vibration abrasion；Overall structure advantages of simple, effectively multiple main shafts 1 can be connected, coupling piece 4
There is the compactness that certain abrasion also can guarantee that its shaft coupling 4 and connecting portion 2 in vibration processes.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
