Description

Adopt the blade marble lockset of milling teeth groove key
Technical field
The utility model belongs to mechanical lock, relates to a kind of blade marble lockset that adopts milling teeth groove key.
Background technology
In the existing lockset, teeth groove on the key has only a kind of form, or teeth groove is located at the side (outer mill teeth groove) of key spoon sheet, or be located at the middle part (interior mill teeth groove) of spoon sheet, make the size of key of lock be restricted, mutual opening rate strengthens, and theftproof performance is affected.
The utility model content
The purpose of this utility model is at above-mentioned situation, and a kind of blade marble lockset that can improve size of key and reduce the employing milling teeth groove key of mutual opening rate is provided.
The blade marble lockset of employing milling teeth groove key of the present utility model comprises tapered end and supporting key thereof:
Described tapered end comprises preceding lock core and the rear lock core in lock body, the lock body, before lock core upper edge axis to be provided with some be one group blade marble group by two blade marbles, be arranged in the middle part of blade marble group one blade marble of homonymy and the end of another blade marble and be respectively equipped with the projection that extend into keyhole, the opposite side of each blade marble is provided with v-depression, and corresponding each blade marble is provided with the blade marble back-moving spring respectively on the preceding lock core; Before be provided with the locking side column that can match with v-depression on the blade marble, the slide block chute that communicates with the locking side column groove in the locking side column groove on the lock core; Be provided with lock pin in the lock pin chute corresponding on the rear lock core, between lock pin and lock pin chute, be provided with the lock pin back-moving spring with preceding lock core slide block chute; In the locking side column groove, be provided with the sliding shoe that radially matches with locking side column, between sliding shoe and the locking side column along lock core shaft to the contact site that two places adopt the inclined-plane is set at least, an end of sliding shoe is positioned at the slide block chute and contacts with lock pin on the rear lock core; The corresponding breach that has with the lock pin chute on the lock body afterbody is used for the step of rear lock core stop bit can match the lock pin in the lock pin chute with this breach.
Described and the supporting key case spatula sheet of tapered end, mill teeth groove and interior mill teeth groove outside the sidepiece of the one side of spoon sheet and middle part are respectively equipped with are provided with tartar on the sidewall of the sidewall of mill teeth groove and interior mill teeth groove outside one.
Further technical scheme is:
Contact site in the described tapered end is all to adopt the inclined-plane contact between sliding shoe and the locking side column, and perhaps one of them adopts the inclined-plane to contact with another.
In this tapered end, set inclined-plane contact site between sliding shoe and the locking side column, be actually on locking side column, be provided with a plurality of limiting sections with the limit slippage piece along the moving of lock core axial direction, have only when all limiting section simultaneous displacement and could remove restriction the sliding shoe axially-movable.When with the non-matching key lock set, even if having part key tooth flower and blade marble to coincide, the locking side column appropriate section is radially inwardly moved along lock core, place's limiting section on the locking side column is removed the restriction to the sliding shoe axially-movable, but because of being subjected to the restriction of another place's limiting section, sliding shoe still can not can not be unblanked along the lock core axially-movable.Have only with matched key locking side column integral body is radially inwardly moved along lock core, all limiting sections are removed the restriction to the sliding shoe axially-movable simultaneously on the locking side column, realize normally unblanking.In the contact site between sliding shoe and locking side column,, can control sliding shoe moving along the lock core radial motion by the control locking side column along the lock core axial direction owing to have at least one to adopt the inclined-plane to contact with another.
The utility model key is to match with projection on the blade marble respectively by the outer mill teeth groove on the spoon sheet and the tartar on the interior mill teeth groove, and the orderly arrangement of control blade marble realizes unblanking.
The utility model tapered end is owing to be provided with a plurality of contact sites between sliding shoe and locking side column, when making with the non-matching key lock set, the possibility that can control the whole displacement of locking side column (causing unblanking easily) reduces greatly, even it is almost nil, greatly reduce the mutual opening rate of lock thus, improved safety.Because the key that is adopted is provided with outer mill teeth groove and interior mill teeth groove simultaneously, has further improved the size of key of lock and reduced mutual opening rate again, made lockset that better theftproof performance be arranged.
Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
