Description

Adopt the tapered end and the key of adopting vane spring idle rotation lock master structure

Technical field

The utility model belongs to mechanical lock, relates to a kind of tapered end and key that adopts adopting vane spring idle rotation lock master structure.

Background technology

Chinese patent ZL200710034226.3 document discloses the lock core clutch structure that a kind of cylinder of spring lock can dally, as shown in Figure 1, it comprises lock body 2 ', preceding lock core 6 ' and rear lock core 12 ' in the lock body 2 ', be provided with in the preceding lock core 6 ' and can go up the locking side column 3 ' that v-depression 15 ' matches with blade marble 4 ', go up the slide block chute 13 ' that setting communicates with the locking side column groove at preceding lock core 6 ', rear lock core 12 ' is gone up lock pin chute 9 ' the interior placement lock pin 14 ' corresponding with slide block chute 13 ', in slide block chute 13 ', place sliding shoe 1 ', contact for inclined-plane 11 ' between sliding shoe 1 ' and the locking side column 3 ', the other end contacts with lock pin 14 '.This lock core clutch structure is found to come with some shortcomings in actual applications, subject matter is: have only a contact site between sliding shoe 1 ' and the locking side column 3 ', during with the key lock set, coincide as part tartar and pellet shot from a slingshot, front end tartar and pellet shot from a slingshot identical (although other tartar is misfitted) as key, the respective end of locking side column 3 ' will radially inwardly be moved along lock core, under the effect of lock pin back-moving spring, lock pin 14 ' and sliding shoe 1 ' together will be along lock core shaft to a bit of distances of inwardly moving, at this moment before lock pin 14 ' has sub-fraction and extend in the lock core 6 ', with front and back lock core 6 ', 12 ' fuses, realization is unblanked, make the mutual opening rate of lock strengthen, theftproof performance is affected.

In the existing lock, also has a kind of key that adopts the two sides all to be milled with identical tartar, the thickness of this key is bigger, so the lockhole on the tapered end is corresponding bigger, and this just can utilize the instrument that size is thicker and strength ratio is higher to insert the chance that the realization violence is unblanked in the lockhole for the lawless person provides.

The utility model content

The purpose of this utility model is at above-mentioned situation, provides a kind of and can prevent the non-matching key lock set, reduces mutual opening rate, improves the tapered end and the key of the employing adopting vane spring idle rotation lock master structure of safety.

The tapered end of employing adopting vane spring idle rotation lock master structure of the present utility model, comprise preceding lock core and rear lock core in the lock body, preceding lock core upper edge axis is provided with some blade marbles, be provided with the locking side column that can match in the locking side column groove with V-shaped groove on the blade marble, the slide block chute that communicates with the locking side column groove is set on preceding lock core, be provided with lock pin in the lock pin chute corresponding on the rear lock core 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, one end of sliding shoe is positioned at the slide block chute and contacts with lock pin on the rear lock core, and a middle side part of described blade marble is provided with the protuberance that can match with bullet groove on the key.

Described contact site 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.

With the supporting key of the utility model tapered end, comprise a spoon sheet, on a face of spoon sheet, be provided with bullet groove, two cell walls of bullet groove are provided with tartar.

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 protuberance on the blade marble by the tartar on the bullet groove cell wall on the locking plate, and the orderly arrangement of control blade marble realizes unblanking.

The utility model 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 reduces greatly, even almost nil, greatly reduce the mutual opening rate of lock thus, improved safety.Again because the key that adopted has only one side to be provided with bullet groove, and its thickness can reduce, make corresponding the reducing of lockhole of tapered end, can prevent to utilize size is thicker and strength ratio is higher instrument to insert the lockhole violence and unblank, the safety of lock is improved.

Further specify technical solutions of the utility model below in conjunction with accompanying drawing.
