Abstract

The utility model relates to a shaver head which comprises a blade base. A blade and a guidance roller are positioned between the two side walls of the blade base; the blade is positioned in a clamping groove of the two side walls; the blade base is fixed in an outer frame body formed by an upper cover and a lower cover; positioning grooves are formed on the two side walls of the blade base, and form positioning fit with the positioning clamping edges on two side walls of the upper and the lower covers; an opening for exposing the blade and the guidance roller is formed on the upper cover; andlubricating strips are arranged on the two sides of the openings. The utility model overcomes the defects that the intensity of the positioning aluminum buttons of a common shaver head is not high, so that the positioning aluminum buttons can deform and loosen easily and the blade can slip out; and the blade lacks guidance in the sliding cutting. By adopting the design provided by the utility model, the upper and the lower covers fixed with each other surround the two ends of the blade on the whole, so that the positioning reliability of the blade is improved. Besides, the shaver head can basically keep cutting in in the right angle direction to shave completely in the shaving process, and has the advantages of simple and compact structure, flexible direction control and safe and reliableuse.

Description

Razor tool tip

Technical field

The utility model relates to a kind of razor tool tip.

Background technology

Traditional razor tool tip all comprises a framework, is provided with draw-in groove on the relative two side of framework, installs blade in the draw-in groove.For blade being positioned in the draw-in groove the outer aluminium button that positioning blade must be set of draw-in groove.The intensity of aluminium button is not high, just may be out of shape inadvertently to get loose, and blade is skidded off cause unexpected injury.Above-mentioned razor tool tip is in the process of cutting beard of sliding, and its motion incision direction generally all needs to meet at right angles with the bearing of trend of blade cutting edge, and only in right angle orientation motion incision, it is best that the effect that shaves just can reach.Yet in actual use, the motion incision direction of the razor tool tip that the user controls is quite random, frictional resistance increase between cutter head and the human body skin has not only reduced the effect that shaves, and goes back incised wound skin easily in the process that motion incision direction constantly changes.

Summary of the invention

For the location aluminium button intensity that overcomes common razor tool tip in the prior art is not high, easy deformation gets loose and causes blade to skid off; In the slip working angles, lack the guiding design, not only reduced the effect that shaves, but also the problem that hurts skin easily, the utility model provides a kind of razor tool tip, and the location simple in structure, blade of this razor tool tip is reliable, direction to control is flexible, safe and convenient to use.

The technical scheme that its technical problem that solves the utility model adopts is: comprise blade bearing, positioning blade and guide roller between the two side of blade bearing, blade is positioned in the draw-in groove of two side, blade bearing is fixed in the outer framework that is made of loam cake and lower cover, on the two side of blade bearing, be provided with locating slot, locating slot is located with the location edge formation on loam cake, the lower cover two side and is cooperated, on cover and be provided with the opening that exposes blade and guide roller, lubricious strip and back lubricious strip before the opening both sides are respectively equipped with.

The spindle nose of guide roller is arranged on the open axial trough in blade bearing two side, the top of axial trough by on cover the pressing plate gland that forms.

The two side of draw-in groove is forward and backward preceding retainer, the back retainer of being respectively equipped with on the length direction of draw-in groove, and preceding retainer is relative across the draw-in groove dislocation with the back retainer.

Draw-in groove is arranged by the locating piece space that links to each other with the two side and is formed, anchor point on the adjacent positioned piece is that axis is symmetrical arranged with the length of draw-in groove, anchor point on the locating piece is in the arc-shaped, draw-in groove near the width of two side end greater than the width between the adjacent positioned point.Loam cake that interfixes and lower cover have surrounded the two ends of blade on the whole, improved the reliability of blade location greatly, blade in use can keep cutter head substantially along the right angle orientation incision of moving, it is thoroughly clean more to shave, and has advantage simple in structure, that direction to control is flexible, safe and reliable.

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Fig. 1 is a decomposition texture schematic diagram of the present utility model;

Fig. 2 is an assembly structure schematic diagram of the present utility model;

Fig. 3 is a kind of structural representation of draw-in groove in the utility model;

Fig. 4 is the another kind of structural representation of draw-in groove in the utility model.

The specific embodiment

As shown in the figure, the utility model comprises blade bearing 1, positioning blade 3 and guide roller 4 between the two side 2 of blade bearing 1, blade 3 is positioned in the draw-in groove 5 of two side 2, draw-in groove 5 can have multiple structural design, a kind of is the two side 2 of draw-in groove 5 retainer 18, back retainer 19 before forward and backward being respectively equipped with on the length direction of draw-in groove 5, and preceding retainer 18 and back retainer 19 misplace relative across draw-in groove 5; Another kind is that draw-in groove 5 is formed by the locating piece 16 spaces arrangement that links to each other with two side 2, anchor point 17 on the adjacent positioned piece 16 is that axis is symmetrical arranged with the length of draw-in groove 5, anchor point 17 on the locating piece 16 is in the arc-shaped, draw-in groove 5 near the width of two side 2 ends greater than the width between the adjacent positioned point 17.Certainly can also be by other design.Blade bearing 1 is fixed in the outer framework that is made of loam cake 6 and lower cover 7, and the said fixing structure can be on the two side 2 of blade bearing 1 locating slot 8 to be set, and locating slot 8 is located with location edge 9 formation on loam cake 6, lower cover 7 two sides and cooperated.Loam cake 4 and lower cover 5 can be by the plastic pressure injection moulding, between the two can ultrasonic bonding or the mode that is clasped be fixedly linked, loam cake 6 is provided with the opening 10 that exposes blade 3 and guide roller 4, lubricious strip 11 and back lubricious strip 12 before opening 10 both sides are respectively equipped with.Loam cake 6 that interfixes and lower cover 7 have surrounded the two ends of blade 3 on the whole, have improved the reliability of blade 3 location greatly.The spindle nose 13 of guide roller 4 is arranged on the open axial trough 14 in blade bearing 1 two side, and the top of axial trough 14 is by pressing plate 15 glands that form on the loam cake 6.The design of guide roller 4, what make blade 3 in use can keep cutter head substantially along the right angle orientation incision of moving, and it is thoroughly clean more to shave.
