shaver having exchange structure of changeable razor blade cartridges

摘要

A razor having a blade exchange structure is disclosed. A razor having a blade cartridge replacement structure according to the present invention comprises a handle having a coupling hole formed at one end thereof and having an operation hole communicated with the coupling hole on an upper surface thereof, And a blade cartridge which is selectively coupled to the coupling means and integrated with the handle, wherein on both sides of the back surface of the blade cartridge, openings are provided, which are open in mutually opposing directions, A pair of arcuate adjustment grooves are respectively formed in the guide rails and the engaging means is formed with a guide protrusion having a guide hole at the center of one end face of the blade facing the back face of the blade cartridge, Grooves are formed, and on both sides of the spring guide grooves, Respectively; And the other end is formed into a rotation support protrusion for supporting the rotation by being inserted into the support groove, and each of the side surfaces is provided with the fitting protrusion side A rotation support member formed on each of the inner sides of the lower housing so as to be positioned on both sides of the guide protrusion; A rotation support spring installed between the spring guide groove and the guide projection and having both ends thereof coupled to both of the rotation support members to elastically support both rotation support members; A pressing member which is engaged with a guide hole of the guide projection at one end and is engaged with a pressing spring provided at the spring guide groove at the other end to press the back surface of the blade cartridge at a predetermined pressure; An inclined surface operating protrusion coupled to the other end of the pressing spring for pushing each of the inclined surfaces provided on both the rotation supporting members to separate the fitting protrusions from the respective weir adjustment grooves on both sides, An actuating member coupled to the lower housing to reciprocate linearly in an operating direction of the pressing member; An upper housing coupled to an upper portion of the lower housing to form an operation space between the upper housing and the lower housing, the upper housing having a through hole for exposing a portion of the operation member on an upper surface thereof; And an operation knob coupled to the operation member via the operation hole in a state where the lower housing and the upper housing are coupled to each other and inserted into the engagement hole to advance the operation member to separate the blade cartridge . According to the present invention, the blade cartridge can be separated from the handle only by advancing the operation knob, and each fitting protrusion of the rotation support members of both sides are fitted into the arched adjustment groove formed in an arc shape on both sides of the blade cartridge, Not only the swing angle can be adjusted smoothly within the allowable angle of the cartridge adjusting groove in the cartridge but also the pressing member presses the back surface of the blade cartridge at an appropriate pressure so that the multiple blades provided on the front surface of the blade cartridge come into close contact with the skin, It is possible to provide an effect that the cutting can be performed stably.;
