Abstract

Disclosed is a razor blade set which comprises a lower blade integrally formed by ceramic and an upper blade made by metal. The lower blade comprises a cutting edge body with cross section of the front portion to be triangular and two outwards-protruding positioning blocks with the rear portions arranged obliquely, rack grooves which are uniformly distributed are formed in a lower bottom plane of the cutting edge body, a front end side of the cutting edge body is provided with a tooth edge side communicated with the rack grooves, and a concave groove is transversely formed at a position position on the cutting edge face and on the inner side of the tooth edge side; an upper plane of the cutting edge body and upper planes of the outwards-protruding positioning blocks are on a same oblique plane contacting with the upper blade and being in mutual shearing with the same, a shovel-shaped included angle is formed between the oblique plane and the lower plane of the cutting edge body, and the outwards-protruding positioning blocks are integrally connected with the cutting edge body through a strip-shaped connecting block. The razor blade set has the advantages of reasonable structure, convenience in mounting and using, high durability, good heat-radiating effect, simple manufacturing process, low cost and the like.

Description

A kind of razor blade group

Technical field

What the present invention relates to is a kind of razor blade group, belongs to razor technical field.

Background technology

The existing set of blades of having one's hair cut, mainly comprise that cutter and bottom knife combine, the set of blades of having one's hair cut described in inciting somebody to action is arranged on shaves on frame, and wherein bottom knife is fixed, and is mainly adjacent at shaved head, by one group of transmission mechanism, drive cutter wherein to move left and right, form the mutual cutting between cutter and bottom knife, because the edge of cutter and bottom knife is respectively arranged with crown, therefore, the result of cutting is mutually, by the hair quick shearing being plugged on crown.The upper bottom knife of the existing set of blades of having one's hair cut processes by metal substantially, often shear the cognate that wearing and tearing or blade easily occur, and heating conduction is too fast between upper bottom knife, causes the heating of full wafer bottom knife, the effect that impact is had one's hair cut to people.

Summary of the invention

The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of, with pottery, make, especially zirconia raw material is made, rational in infrastructure, easy to install, durability is good, good heat dissipation effect, manufacture craft is simple, the ceramic razor blade that cost is low.

The object of the invention is to complete by following technical solution, described razor blade group, it comprises a bottom knife being made of one piece with pottery and uses metal cutter, described bottom knife comprises two evagination locating pieces of the oblique setting of blade bodies and rear portion that front cross section is triangular in shape, on the lower baseplane of wherein said blade bodies, offer uniform rach slot, and in the front end edge of blade bodies, be to offer the land limit that is communicated with described rach slot, be positioned at blade bodies above, inner side, land limit is horizontally arranged with a concave groove; On two evagination locating pieces of the upper plane of described blade bodies and oblique setting, plane is in the same oblique plane that contacts with cutter and mutually shear, and between this oblique plane and the lower plane of blade bodies, is formed with a spade angle.

Two described evagination locating pieces are connected with blade bodies by a connection bar blocks, on described two evagination locating pieces, be respectively arranged with locating hole, and on the evagination locating piece at two locating hole places, be respectively arranged with parallelly with described Baltimore groove mutually in collinear horizontal grooving, and on the upper and lower surface of described connection bar blocks, offer respectively at least one inner groove faces.

Described connection bar blocks is connected on the upper end of described blade bodies mutually, and on it, the upper plane of plane and blade bodies, after same plane, is formed with a concane gap in the blade bodies lower surface of joint; Described connection bar blocks above in the middle of be provided with inner groove faces on, and below connecting bar blocks, be positioned at described on the both sides of inner groove faces be respectively provided with inner groove faces.

The invention belongs to a kind of improvement to prior art, its adopts pottery, especially adopts zirconia ceramics material to be made into integration, and not only intensity, fastness are large, and anti-wear performance is good, in actual use, and with metal cutter, be combined rear mutual shearing, played good roll flute effect; Due to the bottom knife human body surface of directly conflicting, the heat-conductive characteristic of pottery is poor, service time one is long, virgin metal blade contact human body skin surface has blanching sensation, and adopt ceramic tip to contact human body surface, can be because being transmitted on ceramic tip, thus the result of use of razor improved.

The present invention has rational in infrastructure, easy to install, and durability is good, good heat dissipation effect, the feature such as manufacture craft is simple, and cost is low.

Accompanying drawing explanation

Fig. 1 is the structural representation above of bottom knife of the present invention.

Fig. 2 is the structural representation below of bottom knife of the present invention.

Fig. 3 is that Figure 1A is to side-looking structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1-3, razor blade group of the present invention, it comprises a bottom knife being made of one piece with pottery 1 and with metal cutter (not shown), described bottom knife 1 comprises two evagination locating pieces 3 of front cross section blade bodies triangular in shape 2 and the oblique setting in rear portion, on the lower baseplane of wherein said blade bodies 2, offer uniform rach slot 4, and the front end edge in blade bodies 2 is to offer the land limit 5 that is communicated with described rach slot 4, be positioned at blade bodies 2 above, 5 inner sides, land limit are horizontally arranged with a concave groove 6, this Baltimore groove 6 can reduce the contact area between cutter and bottom knife, the heat that reduction produces because of friction, on two evagination locating pieces 3 of the upper plane 7 of described blade bodies 2 and oblique setting, plane 8 is in the same oblique plane that contacts with cutter and can mutually shear, and between this oblique plane and the lower plane of blade bodies 2, being formed with a spade angle, is also a leg-of-mutton obtuse angle.

Shown in figure, two evagination locating pieces 3 of the present invention are connected with blade bodies 2 by a connection bar blocks 9, on described two evagination locating pieces 3, be respectively arranged with locating hole 10, and on the evagination locating piece 3 at two locating hole 10 places, be respectively arranged with parallel with described Baltimore groove 6, mutually in collinear horizontal grooving 11, and on the upper and lower surface of described connection bar blocks 9, offer respectively at least one inner groove faces 12, arranging of described inner groove faces 12 can reduce ceramic raw material, reduce costs, and in the situation that not reducing connection bar blocks 9 intensity, weight reduction, increase fastness, increase heat-delivery surface.

Connection bar blocks 9 of the present invention is connected on the upper end of described blade bodies 2 mutually, on it, the upper plane of plane and blade bodies 2 is after same plane, blade bodies 2 lower surfaces in joint are formed with a concane gap 13, described connection bar blocks 9 above in the middle of be provided with inner groove faces 12 on, and below connecting bar blocks 9, be positioned at described on the both sides of inner groove faces 12 be respectively provided with inner groove faces 12.
