Description

Technical Field

[0001] The utility model relates to the field of razor mechanical structures, in particular to a multi-groove stable razor head structure. Background Art

[0002] There are three existing methods for fixing the razor blade head. The first is to fix it by riveting, that is, there is a column on the upper cover, and the column is cold-riveted or hot-riveted with a tool to deform it to fix the blade. The second is to fix it by riveting and bending aluminum sheets / stainless steel. It is necessary to make the aluminum sheet / stainless steel into the initial shape and put it into the corresponding card slot, and then bend the aluminum sheet / stainless steel to clamp and fix the blade. These two methods will make the blade non-detachable, and the blade head can only be used once, which increases the cost of use.

[0003] The third method is to fix the blade by ultrasonic wave, which means that an ultrasonic line is set on the blade holder, and the upper cover is put in and the two are fixed by an ultrasonic machine. This method has a high scrap rate and unstable process.

[0031] Specifically, in order to provide a detachable razor blade 3 and improve the fixing strength of the blade 3, a blade cover 2 is provided, such as Figure 1 and 2 As shown, the blade end of the blade 3 is upward, and the edges on both sides of the blade end are blunt surfaces, which are movably connected to the protrusion 22. The blade 3 can be selected from one or more of the following specifications and shapes: spot welding blade, bending blade, flat blade; further, the description of the blade 3 is only for the convenience of understanding of those skilled in the art, and those skilled in the art can use any alternative available on the market or any alternative that can be thought of based on the content of the specification of the utility model; the back end of the blade 3 is downward, and both ends are fixed in the blade groove 12. The blade 3 is squeezed and fixed by the blade cover 2 and the blade holder 1 at the top and bottom, so the blade 3 The fixation is transferred to the fixation of the blade cover 2 and the blade holder 1. Ensuring that the blade cover 2 and the blade holder 1 are firmly fixed can ensure that the blade 3 is firmly fixed and not loose; further, the blade cover 2 is annular and buckled on the blade holder 1. The top of the blade holder 1 is hollowed out in an annular shape, and the shape is matched with the setting of the blade cover 2, so that the blade 3 can be separated, disassembled and replaced; when the blade cover 2 is buckled on the blade holder 1, the buckle 21 is stretched outward to the height of the buckle groove 11 and rebounds inward to buckle. The buckle 21 is set to a structure with a buckling complexity lower than the separation complexity, and preferably can be used as Figure 4 , 5 The structure shown or any replacement thereof is intended to make the removal and installation difficulty of the buckle 21 asymmetrical, thereby facilitating installation while ensuring the fixing strength of the blade 3 .

[0032] Among them, the up and down refer to the directions in the preferred process of installation with the tool holder 1 as the base, and the inside refers to the direction from the blade cover 2 to the blade 3. The purpose of describing the direction is to facilitate understanding by technicians in this field, and it does not constitute an improper limitation.

[0033] As a preferred implementation of this embodiment, the middle portion of the blade slot 12 is a recessed structure, and both sides of the blade slot 12 are arranged to match the shape of the blade back end. When the multi-slot stable razor head structure is in an installed state, the blade 3 is clamped on both sides of the blade slot 12.

[0034] Specifically, for the blade 3, in the solution of clamping and fixing the blade 3 from top to bottom, preferably, the two sides of the blade groove 12 are configured to match the shape of the blade back. In short, the blade 3 is clamped on both sides of the blade groove 12 to prevent it from tilting due to lateral force, thereby further fixing the blade 3.

[0035] As a preferred implementation of this embodiment, the tool holder 1 further includes a crotch rib, and the position of the crotch rib 13 is arranged in coordination with the position of the buckle slot 11. Preferably, the height of the crotch rib 13 is not lower than the highest point of the buckle slot 11. Preferably, the inner side surface of the crotch rib 13 is inclined outward from low to high, with an inclination angle of α.

[0036] Specifically, the crotch rib 13 of the blade holder 1 is wrapped around the outer side of the blade cover 2, preferably, as Figure 4 As shown, the crotch rib 13 arranged at the outer part of the buckle groove 11 is higher. Since the buckle 21 needs to be stretched outward and separated from the buckle groove 11, the crotch rib 13 wraps the buckle 21 to prevent it from falling off in the event of accidental falling or collision. The blade groove 12, the groove 31 and the buckle groove 11 mutually restrict the blade cover 2, the blade 3 and the blade holder 1 to improve the fixing effect. As a preferred embodiment, Figure 4 As shown, the inner side of the crotch rib 13 is inclined outward. When the blade cover 2 is buckled downward, the inclination guides the buckle 21 downward until it is buckled in the buckle groove 11, which facilitates the positioning of the buckle groove 11.

[0037] As a preferred implementation of this embodiment, the blade holder 1 further includes a rubber surface 14, which is arranged on the side of the blade slot 12. The rubber surface 14 is integrated with the blade holder 1 to increase the surface friction coefficient and prevent the blade 3 from moving too fast and scratching the user.

[0038] As a preferred implementation of this embodiment, one or more of the rubber surfaces 14 further include a lubricating strip 15, the purpose of which is to reduce irritation to the skin and play a lubricating role.

[0039] As a preferred implementation manner of this embodiment, the number of the rubber surfaces 14 is 2, the number of the lubricating strips 15 is 1, the number of the buckle grooves 11 is 6; the number of the blades 3 is 3, and the number of the blade grooves 12 is 6.

[0040] Preferably, the cross-section of the main body of the multi-slot stable razor head structure is a rounded rectangle, and the buckle slots 11 are arranged in two pairs on the longer opposite sides of the rounded rectangle and in one pair on the shorter opposite sides.

[0041] As a preferred implementation of this embodiment, the tool holder 1 further includes a positioning groove 16, and the blade cover 2 further includes a positioning head 23, the positioning head 23 is configured to match the positioning groove 16 in shape, and the positioning head 23 is movably connected in the positioning groove 16. Specifically, the positioning head 23 is cylindrical, and the positioning groove 16 is a matching cylindrical groove 31, the purpose of which is to locate the buckling position of the blade cover 2 to prevent damage caused by incorrect buckling position.

[0042] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes. The scope of the utility model is intended to be defined by the claims and their equivalents.
