Abstract

The utility model relates to high-speed hair clippers. The reciprocating motion of a handle is changed to a high-speed rotating motion through a rack and a multi-stage speed changing system and then is changed into the reciprocating oscillation of an oscillating arm through an eccentric wheel mechanism, and therefore, a movable clipping sheet is driven to do high-speed oscillation opposite to a fixed clipping sheet. The hand-operating high-speed hair clippers achieves the function of high-speed hair clipping without using other power, particularly being suitable for villages and mobile hair clipping.

Description

Hand-operating high-speed hair clippers

The utility model belongs to hair dressing tools, particularly relates to a kind of manual hair scissors.

Existing hair scissors generally has electronic cutting with hand push to cut two kinds, and it is the grip of utilizing hand that hand push is cut, and each time grip is converted into moving back and forth of active cutter plate, cooperates and decide snip, makes to produce slip relatively between moving plate and the stator, finishes the hair-cutting function.Manually hair clipper are simple and reliable for structure, but because of power is used manually fully, hold once, only move back and forth once between the moving plate stator, thereby wanting to make manual hair clipper to produce the speed of getting a haircut faster, the user just must ceaselessly receive fast to hold and loosen the hair clipper handle, like this hand fatiguability, and influence the stable of hair clipper, unfavorable to the haircut quality.Also be difficult to the haircut speed that reaches desirable.

Electronic hair clipper have overcome above-mentioned shortcoming, but cost is higher, and are subjected to the restriction of power supply, in vast rural area because of the supply of electric power deficiency makes electronic hair clipper can't operate as normal, particularly, can not be extensive use of because of obtaining the power supply supply for the haircut of flowing out of doors.The purpose of this utility model provides a kind of simple structure, can use the manual high speed hair scissors of manual generation THE ADIABATIC SHEAR IN action.This hair scissors does not need any external power, thereby can be widely used in the place that is not subjected to the Power Supplies Condition restriction.

The purpose of this utility model is to adopt following scheme to realize: increase the step-by-step variable gear group between the manual pressure handle of hair scissors and active cutter plate, the back and forth movement of pressure handle is passed through tooth bar, gear train becomes high speed rotary motion, make swing arm do bidirectional swinging by eccentric cam again, drive the swing of active cutter plate high-speed bidirectional, reach the purpose of quick hair-cutting, like this as long as suitably design gearratio, hold hair clipper once, the wobbling action of active cutter plate can reach tens times.

Below in conjunction with accompanying drawing the utility model is elaborated;

Accompanying drawing 1 is the vertical view of the manual high speed hair scissors of the utility model

Accompanying drawing 2 is side views of the manual high speed hair scissors of the utility model

As can be seen from Figure 1, the utility model high speed hair scissors mainly is made up of following several parts: the hair clipper body, the hair clipper handle, variable transmission mechanism and snip, the hair clipper handle comprises that a pressure is (10), pressure is connected with pressure driving rack (11) to (10) front end, and middle by energy-storaging spring (12) support, the rear end is fixed on the hair clipper body by steady pin (19).Pressure serves as (10) that axle rotates with steady pin (19).Variable transmission mechanism is made up of transfer motion speed changing gear several, the pinion of pressure driving rack (11) and first order travelling gear (5), then by the level Four travelling gear, the reciprocating motion of tooth bar (11) becomes high speed rotary motion the most at last, as can be seen from the figure, the gear wheel of previous stage and back one-level pinion make gearratio increasing.

The snip group is by active cutter plate (2) and decide snip (1) and form, and active cutter plate (2) embeds the front end of swing arm (17), decides snip (1) and is fixed on the hair clipper body (3), and screw (7) is the hold-down screw of energy-storaging spring (12).Tooth bar locating wheel (4) is the directive wheel of pressure tooth bar (11), makes tooth bar (11) and first order change-speed gearing (5) be in engagement all the time.

Fig. 2 is the hair scissors side view, as can be seen from the figure, travelling gears at different levels all have small one and large one coaxial two gears, the pinion of the gear wheel of upper level travelling gear and next stage travelling gear reaches the purpose of accelerating rotation, for example: the pinion of the gear wheel of first order travelling gear (5) and second level travelling gear (6) reaches the one-level speed change.Eccentric cam (15) rotates in elliptical aperture (18), swing arm (17) is produced swing back and forth, and active cutter plate (2) is embedded in the front end of swing arm (17), decides the snip reciprocally swinging relatively thereupon.

The action principle of high speed hair scissors is as follows: when user's grip pressure power handle (10), pressure draws the elastic force that overcomes energy-storaging spring (12) in, tooth bar (11) linear reciprocating motion, and by driving whole change-speed gearing group rotation with first order gear (5), the change-speed gearing group is by step-by-step variable gear (5), (6), (8), (9), after speed change, make gear (9) high speed rotating, because of there is an eccentric cam (15) gear (9) below, and eccentric cam (15) is in the elliptical aperture of swing arm (17) rear end, therefore swing the rear end of the rotating band movable pendulum swing arm (17) of eccentric cam (15), thereby the swing arm front end is also swung, hair clipper moving plate (2) is to be embedded in the swing arm front end, also swing thereupon,, the swing speed of hair clipper moving plate (2) is accelerated because of the effect of the multi-change speed transmission of change-speed gearing group, stator (1) is made the high speed reciprocating swing relatively, reaches the purpose of hair-cutting.

When the user loosens pressure (10), pressure is pulled back (10) under the effect of energy-storaging spring (12), tooth bar (11) is toward the rightabout motion, driving whole change-speed gearing group rotates, make active cutter plate (2) high speed swinging equally, therefore, the user need only press pressure with relatively slow action just can high speed swinging (10) and active cutter plate (2), reaches good haircut effect.

The effect of range line steel wire (13) is restricted the open angle of energy-storaging spring (12), and unlikely hair clipper body and the gear of skidding off of tooth bar (11) broken away from.

Claims (3)

1, a kind of manual high speed hair scissors is by the hair clipper body, the hair clipper handle, variable transmission mechanism and snip mechanism form, it is characterized in that: the front end of hair clipper handle is connected with pressure driving rack (11), and middle partly with energy-storaging spring (12) support, the rear end is fixed on the hair clipper body (3) with bearing pin; Variable transmission mechanism is made up of the level Four travelling gear, and the engagement of pressure driving rack (11) and first order gear (5) has an eccentric wheel (15) below the fourth stage travelling gear (14), and eccentric wheel (15) is in the rear end elliptical aperture of swing arm (17); Snip mechanism is by swing arm (17), be embedded in the active cutter plate (1) (2) of swing arm (17) front end and fixedly the snip (1) of deciding on the hair clipper body (3) form.

2, manual high speed hair clipper according to claim 1 is characterized in that: be equipped with spacing steel wire (13) on the energy-storaging spring (12), energy-storaging spring (12) rear end is fixing by spring hold-down screw (7).
