Abstract
The utility model discloses an inner razor bit for rotary razor, has the advantages of simple processing, high intensity of an inner razor body, and low cost, and mainly comprises an internal support ring (1) and an external support ring (2). A plurality of internal support pillars (4), which are distributed along the circumferential direction, are arranged on the internal support ring (1), and a plurality of external support pillars (5), which are distributed along the circumferential direction, are arranged on the external support ring (2) corresponding to the internal support ring (1). The inner razor body (3) is arranged between one end of an internal support pillar (4) and one end of a corresponding external support pillar (5). A cutting edge (6) is formed by the top side of each inner razor body (3) and the front side wall of the inner razor body (3).
Description
Technical field
The utility model relates to cutter head in a kind of razor.
Background technology
Cutter head and outer cutter head in razor cutter head in the market generally comprises, outer cutter head is general to keep motionless, interior cutter head can rotate with respect to outer cutter head, so interior cutter head also is called dynamic cutter head, cutter head mainly comprises a plane annular supporting member and a plurality of direct bearing post that erects from the neighboring of plane annular supporting member and is formed on interior cutter hub on the direct bearing post end in the razor of prior art.Cutter head in the razor of this structure, cutter hub has only a direct bearing post in each, and interior cutter hub intensity is lower, to the material requirements height, processed complex, cost is higher, and the interior cutter hub that is processed to form annular precision is relatively poor, is unfavorable for and being rotatably assorted of outer cutter head.
Summary of the invention
The purpose of this utility model provides a kind of cutter head in the razor that simple, interior cutter hub intensity is higher, cost is low of processing.
For achieving the above object, the utility model is by the following technical solutions: cutter head in a kind of razor, mainly comprise internal support ring and external support ring, internal support is equipped with a plurality of internal support columns that along the circumferential direction distribute, external support ring correspondence is provided with a plurality of external support posts that along the circumferential direction distribute, be provided with interior cutter hub between the end of a terminal and corresponding external support post of an internal support column, the end face of cutter hub and its front side wall form cutting edge in each.
In the technique scheme, because cutter hub is formed on the end of an internal support column and a corresponding external support post in each, cutter hub has two strong points in each, and the intensity of interior cutter hub improves greatly, therefore can reduce the requirement to material, thereby reduce cost; Cutter head can be made by the annular solid cutting of band internal support ring and external support ring in the utility model razor, so the process simplification, has saved cost; Because the internal support column of cutter hub and external support post along the circumferential direction distribute on internal support ring and external support ring respectively in each, the interior cutter hub annular precision height that therefore forms helps and being rotatably assorted of outer cutter head.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the general structure schematic diagram of a kind of embodiment of cutter head in the utility model razor.
Fig. 2 is the vertical view of the interior cutter head of razor among Fig. 1.
Fig. 3 is the partial side view of the interior cutter head of razor among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of embodiment of cutter head in the utility model razor, mainly comprise internal support ring 1 and external support ring 2, internal support ring 1 is provided with a plurality of internal support columns 4 that along the circumferential direction distribute, external support ring 2 correspondences are provided with a plurality of external support posts 5 that along the circumferential direction distribute, cutter hub 3 in being provided with between the end of a terminal and corresponding external support post 5 of an internal support column 4, the end face of cutter hub 3 forms the cutting face of matching with outer cutter head in each, mating surface shape according to outer cutter head, the end face of cutter hub 3 can be processed into the horizontal cutting face in each, also can be processed into the circular arc cutting face, the end face of cutter hub 3 and its front side wall form cutting edge 6 in each.In order more to help forming cutting edge, described internal support column 4 along the circumferential direction is obliquely installed on internal support ring 1, correspondingly external support post 5 also along the circumferential direction is obliquely installed outside on the support ring 2, internal support column 4 is identical with the incline direction of external support post 5, the cutting edge 6 of cutter hub 3 is positioned at the edge (be the edge of front side wall) of inclination angle less than 90 degree sidewalls in each as shown in Figure 3, and the angle of inclination a of described internal support column 4 and internal support ring 1 and external support post 5 are 40～60 degree with the preferred range of the angle of inclination a of external support ring 2.In order to reach the purpose of this utility model better, described internal support column 4 along the circumferential direction width can help processing, the intensity of cutter hub in also can increasing on the other hand on the one hand less than external support post 5 width along the circumferential direction.
Claims (4)
1, cutter head in a kind of razor, it is characterized in that: mainly comprise internal support ring (1) and external support ring (2), internal support ring (1) is provided with a plurality of internal support columns (4) that along the circumferential direction distribute, external support ring (2) correspondence is provided with a plurality of external support posts (5) that along the circumferential direction distribute, be provided with interior cutter hub (3) between the end of the end of an internal support column (4) and a corresponding external support post (5), the end face of cutter hub (3) and its front side wall form cutting edge (6) in each.
2, cutter head in the razor according to claim 1, it is characterized in that: described internal support column (4) along the circumferential direction is obliquely installed on internal support ring (1), correspondingly external support post (5) also along the circumferential direction is obliquely installed outside on the support ring (2), and internal support column (4) is identical with the incline direction of external support post (5).
3, cutter head in the razor according to claim 2 is characterized in that: described internal support column (4) all is 45 degree with the angle of inclination of internal support ring (1) and the angle of inclination of external support post (5) and external support ring (2).
4, according to cutter head in claim 1 or the 2 or 3 described razors, it is characterized in that: described internal support column (4) along the circumferential direction width less than external support post (5) width along the circumferential direction.
