Abstract

The utility model relates to a rotating shaver screen, wherein the central portion of the rotating shaver screen is provided with several through-holes, and both faces of the central portion are provided with plastic discs shaped by injection moulding, the plastic discs are connected to be integration through the through-holes and are closely combined with the central portion, the center of the inboard of the plastic disc is provided with a positioning protruding shaft movably engaged with a central positioning hole of the rotating shaver, an annular vertical wall is embedded on an annular plastic support to form integration. Due to the consolidation and the support of the plastic discs and the plastic support are both provided, the metal elements can be fabricated with very thin sheets and manufactured by adopting the electro moulding art, the rotating shaver with these structures greatly simplifies the productive technology, reduces the cost and has no need for high-grade precision and sophisticated equipment.

Description

The rotary shaver guard

The utility model relates to a kind of rotary shaver guard.

Known rotary shaver guard all is through repeatedly punching stretch shaping with thicker sheet metal as the outer part that shaves (being the shaver guard) that is disclosed among the US-A-4675998, and through repeatedly grinding, enter the palpus hole with accurate equipment making then, therefore promptly expend metal material, processing technology is complicated again, equipment requires high again, and production cost is high.

The purpose of this utility model is to provide a kind of consumptive material few, and processing technology simply, does not need the rotary shaver guard of the low production cost of advanced equipments of high grade and precision.

The purpose of this utility model is to realize by such scheme: the rotary shaver guard still comprise a annular of making by metal material a little more than central part advance must orifice ring and advance must the orifice ring outer rim annular wall, advance to be evenly equipped with on must orifice ring roughly with advancing of radial parallel must the hole, the blade rotational trajectory that advances medial surface and rotary shaver that must orifice ring is the close neighbour mutually, central part at the rotary shaver guard is provided with several through holes, this central part two sides is provided with the plastic disc of injection molded, the plastic disc via through holes links into an integrated entity and combines closely with central part, the center of inboard plastic disc also is provided with and the protruding axle in razor center positioning hole location movingly, and annular wall is embedded on the annular plastics support and constitutes one

Adopt the razor of said structure, because the reinforcing and the supporting of plastic disc and plastic stent have been arranged, its metal parts can be used very thin board making, only need 0.05～0.1mm thick, and the thick metal guard of 0.05～0.1mm can adopt the electroforming process manufacturing, and can make into palpus hole simultaneously, therefore simplified production technology widely, reduced cost and do not needed high-grade, precision and advanced equipment.

The utility model is described in further detail and provide embodiment simultaneously below in conjunction with accompanying drawing.

Fig. 1 is the utility model example structure schematic diagram;

Fig. 2 is the utility model embodiment generalized section.

As shown in Figure 1, advance palpus orifice ring 1, advance palpus hole 9 and the 7 employing electroforming process manufacturings of annular wall, thickness be 0.05～0.1mm this, and in the central part center of circle and concentric five equilibrium ground, contiguous place be provided with four through holes 4 altogether, the lower edge of annular wall 7 turns up and constitutes outer rotating edge (8), adopt the mode of injection molded at its both sides shaping plastic disc 5 and 6 at central part, and combine closely with it, the height of disk 5 enters the plane of palpus orifice ring 1 a little less than annular, center at plastic disc 6 goes out and the protruding axle 3 in razor center positioning hole location movingly with plastics forming simultaneously, in order to location to razor, injection molded has plastic stent 2 on annular wall 7 and outer rotating edge 8, annular wall 7 is embedded constitutes one therein, the upper surface of plastic stent 2 a little less than annular advance must orifice ring 1 the plane, the exterior contour of plastic stent 2 can design as required.

Claims

1, a kind of rotary shaver guard, comprise a annular of making by metal material a little more than central part advance must orifice ring and advance must the orifice ring outer rim annular wall, advance to be evenly equipped with on must orifice ring roughly with advancing of radial parallel must the hole, the blade rotational trajectory that advances medial surface and rotary shaver that must orifice ring is the close neighbour mutually, it is characterized in that: the central part of described rotary shaver guard is provided with several through holes (4), this central part two sides is provided with the plastic disc (5 of injection molded, 6), plastic disc (5,6) via through holes (4) links into an integrated entity and combines closely with central part, the center of inboard plastic disc (6) also is provided with and the protruding axle in razor center positioning hole location movingly (3), and annular wall (7) is embedded at annular plastics support (2) and goes up the formation one.

2, rotary shaver guard according to claim 1 is characterized in that: annular wall (7) is provided with outer rotating edge (8).

3, rotary shaver guard according to claim 1 and 2 is characterized in that: the thickness that annular is advanced palpus orifice ring (1), annular wall (7) and central part is between 0.05～0.1mm.
