Abstract
The present invention relates to a movable cutter head of a rotary shaver, which is simple to process; na inner cutter body has high strength and low cost. The movable cutter head of a rotary shaver comprises an inner supporting ring (1) and an outer supporting ring (2), wherein an annular supporting surface (5) is arranged between the inner supporting ring (1) and the outer supporting ring (2). A plurality of beard discharging holes (6) and a plurality of inner cutter bodies (4) are arranged on the annular supporting surface (5). The bottom end of each of the inner cutter bodies (4) is connected with the edge of one longitudinal side of each of the beard discharging holes. A cutting surface (3) is arranged at the top end of each of the inner cutter bodies (4). The cutting surface (3) of each of the inner cutter bodies (4) and the front side surface of each of the inner cutter bodies (4) are formed into a cutting edge (7).
Description
Technical field
The present invention relates to a kind of dynamic cutter head of rotary razor.
Background technology
Razor cutter head in the market generally comprises dynamic cutter head and outer cutter head, outer cutter head is general to keep motionless, dynamic cutter head can rotate with respect to outer cutter head, dynamic cutter head is located at the inside of outer cutter head, so dynamic cutter head also is called interior cutter head, the dynamic cutter head of rotary razor of prior art mainly comprises a ring-shaped bearing piece and a plurality of direct bearing post that erects from the neighboring of ring-shaped bearing piece and is formed on interior cutter hub on the direct bearing post end.The dynamic cutter head of rotary razor of this structure, because interior cutter hub is located on the end of direct bearing post, interior cutter hub intensity is relatively poor, the processing technology complexity, cost is higher, and the interior cutter hub annular precision that is processed to form is relatively poor, is unfavorable for and being rotatably assorted of outer cutter head.
Summary of the invention
The purpose of this invention is to provide a kind of dynamic cutter head of rotary razor that simple, interior cutter hub intensity is higher, cost is low of processing.
For achieving the above object, the present invention is by the following technical solutions: a kind of dynamic cutter head of rotary razor, comprise internal support ring and external support ring, be provided with annular bearing surface between internal support ring and the external support ring, annular bearing surface is provided with a plurality of rows' palpuses hole, and annular bearing surface is provided with a plurality of interior cutter hubs, and the bottom of interior cutter hub is connected with vertical lateral edges in row's palpus hole, the top of interior cutter hub is provided with the cutting face, and the cutting face of cutter hub and its leading flank form cutting edge in each.
In the technique scheme, because cutter hub is arranged on the annular bearing surface in each, and annular bearing surface is connected support jointly by internal support ring and external support ring, and the intensity of therefore interior cutter hub can improve; Dynamic cutter head of rotary razor of the present invention in addition can and be bent into by the punching press of planar rings body, and not only process is simple, has saved cost, and the interior cutter hub that is processed to form annular precision is higher, helps and being rotatably assorted of outer cutter head.
The invention 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 dynamic cutter head of rotary razor of the present invention.
Fig. 2 is the vertical view of dynamic cutter head of rotary razor among Fig. 1.
Fig. 3 is the side view of dynamic cutter head of rotary razor among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, dynamic cutter head of rotary razor of the present invention a kind of embodiment, comprise internal support ring 1 and external support ring 2, be provided with annular bearing surface 5 between internal support ring 1 and the external support ring 2, annular bearing surface 5 is provided with a plurality of rows' palpuses hole 6, annular bearing surface 5 is provided with a plurality of interior cutter hubs 4, the bottom of interior cutter hub 4 is connected with vertical lateral edges in row's palpus hole 6, the top of interior cutter hub 4 is provided with cutting face 3, in each match with outer cutter head in the cutting face 3 of cutter hub 4, mating surface shape according to outer cutter head, the horizontal cutting face can be processed in the cutting face 3 of cutter hub 4 in each, also can be processed into the circular arc cutting face, the cutting face 3 of cutter hub 4 forms cutting edge 7 with the leading flank of interior cutter hub 4 in each.For the cutting edge that forms on the cutting face 3 of cutter hub 4 in making sharper keen, cutter hub 4 can be obliquely installed on annular bearing surface 5 in described, interior cutter hub 4 must hole 6 directions tilt to adjacent row, can help processing, also help row's palpus, described interior cutter hub 4 is 40～60 degree with the preferred range of the inclination angle a on horizontal supporting ring 5 planes of living in.
Claims (1)
