Description

A kind of shaver cutter head rotational structure

Technical field

The utility model is related to shaver fields, and in particular to a kind of shaver cutter head rotational structure.

Background technology

Existing multi-knife-head rotation shaver such as publication number CN201179660 patent, U disclosed on 01 14th, 2009 Shape rotation stop holder is mutually buckled with the tongue below middle ring hemisphere, and U-shaped rotation stop holder is fixed on down by annular elastic tape On semi-ring sphere, entire razor group annular rotation is limited, this is complicated, and installs inconvenience.

Utility model content

In order to overcome the shortcomings of that background technology, the utility model provide a kind of shaver knife simple in structure, easy for installation Head rotational structure.

Technical solution used by the utility model：A kind of shaver cutter head rotational structure comprising connection cutter head and machine The connector of body, the connector carry swing mechanism, the swing mechanism be equipped with for limit cutter head circumferentially rotate it is several A salient point.

The swing mechanism includes the matched upper half ring sphere of three, middle semi-ring sphere and the global body of lower half, institute It states upper half ring sphere and the global body of lower half is socketed on middle semi-ring sphere or more centered on middle semi-ring sphere, upper half ring sphere is under Semi-ring sphere is fixedly connected, and comprehensive swing is done around middle semi-ring sphere.

The salient point is symmetricly set on the outer surface of the middle semi-ring sphere circumferential direction, the upper half ring sphere be equipped with it is described The groove of salient point adaptation.

The salient point is integrally formed with the middle semi-ring sphere.

The salient point is hemispherical.

The inner surface of the middle semi-ring sphere and the global body of lower half is designed with the raised cambered surface being uniformly arranged.

The floating shelf for each cutter head of support is also clamped between the upper half ring sphere and the global body of lower half, it is described floating Moving frame is equipped with several outwardly extending flexible feets.

Each pair of U-shaped bifurcated of the flexible feet.

The utility model has the beneficial effects that：Rotary shaver using the above structure, by the way that symmetrical salient point is arranged Make cutter head that can only do pendulum motion around salient point, limit circumferentially rotating for it, entire cutter head can do 360 degree of sides entirely relative to fuselage Position veneer flexible motion has simple in structure in addition, salient point and middle semi-ring sphere are integrally formed, and production cost is low, easy for installation The advantages of.

Specific implementation mode

The utility model embodiment is described further below in conjunction with the accompanying drawings：

As shown, a kind of shaver cutter head rotational structure comprising the connector 1 of connection cutter head and fuselage, the company Fitting 1 carries swing mechanism 2, and the swing mechanism 2 is equipped with several salient points 3 circumferentially rotated for limiting cutter head, the pendulum Motivation structure 2 includes the matched upper half ring sphere 21 of three, middle semi-ring sphere 22 and the global body 23 of lower half, the upper half ring Sphere 21 and the global body of lower half 23 are socketed on about 22 middle semi-ring sphere, 21 He of upper half ring sphere centered on middle semi-ring sphere 22 The global body of lower half 23 is fixedly connected, and the comprehensive rotary shaver swung using the above structure is done around middle semi-ring sphere 22, Make cutter head that can only do pendulum motion around salient point by the way that symmetrical salient point is arranged, limits circumferentially rotating for it, in addition entire cutter head 360 degrees omnidirection veneer flexible motion can be done relative to fuselage, in addition, salient point is integrally formed with middle semi-ring sphere, there is structure Simply, production cost is low, advantage easy for installation.

The salient point quantity of the present embodiment is two, the ranging from 360 degrees omnidirection that cutter head is swung, if setting four or more Multi-convex point can generate limitation to the swing angle of cutter head.

The salient point 3 is symmetricly set on the circumferential outer surface of the middle semi-ring sphere 22, and the upper half ring sphere 21 is equipped with The groove 4 being adapted to the salient point 3, salient point are embedded in installation groove, limit circumferentially rotating for cutter head, only carry out pendulum motion.

The salient point 3 is integrally formed with the middle semi-ring sphere 22, with low, the easy for installation advantage of production cost.

The salient point 3 is hemispherical, reduces resistance when cutter head is swung, improves job stability.

The inner surface of the middle semi-ring sphere 22 and the global body of lower half 23 is designed with the raised cambered surface 5 being uniformly arranged, and subtracts The frictional resistance of upper half ring sphere 21 in few cutter head swing process, middle semi-ring sphere 22 and the global body of lower half 23, face is contacted and is become For point contact, have resistance small, the advantages of reliable operation.

The floating shelf 6 for each cutter head of support is also clamped between the upper half ring sphere 21 and the global body of lower half 23, The floating shelf 6 be equipped with several outwardly extending flexible feets 7,7 U-shaped bifurcated of each pair of flexible feet, the present embodiment Four of five cutter-head rotary shavers, can be under the resilient support effect of the flexible feet of floating shelf 6 in the cutter head of periphery As skin sparing frame such as does 20 degree or so floatings up and down.

Embodiment is not construed as the limitation to utility model, but any spiritual improvements introduced based on the utility model, It should all be within the protection scope of the utility model.
