Abstract
The invention provides a blade idling lock. The blade idling lock comprises a lock case, a lock core, a lock cylinder, blade grooves, blades, a spring and a side column, wherein, the lock core is divided into a front lock core and a rear lock core; a pin tumbler hole is arranged on the lock passing through the front lock core and is equipped with a ball and a pin tumbler; two corresponding convex blocks are arranged in each blade groove in the lock cylinder; each blade groove is equipped with a blade group which respectively comprises key blades interacting with a key and a side column blade interacting with the side column; corresponding sides of each two blades are equipped with the grooves and the convex blocks which are matched with each other so that the two blades can move at the same time; the key blades can not press the side column blade along the direction vertical to the side column; and when two blade groups are positioned in the same blade groove, the grooves and the convex blocks matched with each other are arranged between the key blades. The blade idling lock has the beneficial effects that pressure on the side column blade from the side column can not be changed so that the blade idling lock can not be opened by a technique method, therefore, the blade idling lock has good anti-technical opened performance and stability.
Description
Technical field
The present invention relates to a kind of mechanical lock, particularly relate to lamina idle-run lock.
Background technology
The present lamina idle-run lock that uses, one side blade and the contacted unlatching mouth that cooperates with side column that is provided with of side column, after all side columns and blade unlatching mouthful all cooperated, lamina idle-run lock was in opening, otherwise is in locking states.And technical unlocking adopts non-supporting unlocking tool, fixedly lock gall and lock core, and then each sheet blade compressed on the direction perpendicular to side column, thereby other blade of pressure ratio that this sheet blade is born wants big, stir simultaneously this sheet blade again and survey its unlatching mouth, find the open position of blade, thereby open lamina idle-run lock.And this lamina idle-run lock is to prevent that the space between blade and the blade groove is excessive, when producing, makes the space of blade and blade groove compact, has dust or greasy dirt to enter lamina idle-run lock so slightly, just can not open lamina idle-run lock smoothly.Because of existing appeal not enough, the performance of anti-technical unlocking of this lamina idle-run lock and stability is bad.
Summary of the invention
Can not prevent that in order to overcome existing lamina idle-run lock the deficiency of technical unlocking is bad with stability, a kind of lamina idle-run lock that can prevent technical unlocking and good stability is provided.
The technical solution adopted for the present invention to solve the technical problems is: it comprises lock housing, lock gall, lock core, blade groove, blade, spring and side column, if lock gall is divided into anterior lock core and post lock core two parts, be provided with the pellet shot from a slingshot hole by locking of anterior lock core, be provided with hoodle and lock pellet shot from a slingshot in the hole, the projection of two correspondences is set in the lock core blade groove, place respectively in the blade groove with the key blade of key interaction and with the side column blade of side column interaction be one group vane group, two corresponding limits of blade are provided with the groove and the projection of cooperation, thereby two blades can be moved simultaneously, and key blade can not compress the side column blade on the direction perpendicular to side column.When two groups of vane group are in same blade groove, be provided with the groove and the projection of cooperation between the key blade.
The invention has the beneficial effects as follows, with non-supporting unlocking tool, must make the side column blade bear the pressure of the side column bigger during technical unlocking, stir the unlatching mouth on the key blade detection side column blade simultaneously again than other side column blade.But the corresponding projection that is provided with in the blade groove makes the technical unlocking can't be by key blade toward perpendicular to compressing the side column blade on the side column direction, the pressure of the side column that change side column blade bears, thus can't open lamina idle-run lock by the method for technical unlocking.And corresponding projection is arranged in the blade groove, and making has enough spaces between blade groove and the blade, can not influence blade and move in blade groove.Therefore, this lamina idle-run lock has well anti-technical opening performance and stability.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the positive view of first embodiment.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the positive view of second embodiment.
Fig. 4 is the sectional view of Fig. 3.
1. lock housings among the figure, 2. lock core, 3. side column, 4. spring is 5. opened mouth, 6. groove between vane group and projection, 7. keyhole, 8. blade groove, 9. key blade, 10. side column blade, 11. blade groove projections, 12. anterior lock cores, 13. post lock core, 14. lock pellets shot from a slingshot, 15. pellet shot from a slingshot holes, 16. hoodle, groove between 17. key blade and projection.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, rotating anterior lock core (12), post lock core (13) and lock core (2) are arranged in the lock housing (1), blade groove (8) on the lock core (2) be provided with blade groove projection (11), with the key blade (9) of key interaction and the side column blade (10) interactive with side column (3), and groove and the projection (6) that cooperates between vane group arranged, the unlatching mouth (5) that cooperation is arranged on the side column blade (10) of side column (3) correspondence, spring (4) is compressing side column (3) and side column blade (10) simultaneously, and key can touch key blade (9) by keyhole (7).There are two groups of vane group blade groove among the embodiment of Fig. 3, Fig. 4 (8) lining, is provided with the groove and the projection (17) that cooperate between key blade.
Idle-run lamina lock among the figure is locking states, when using with supporting key operated of this idle-run lamina lock, teeth on the key will compress the key blade of correspondence (9) and move to suitable position, interlock by groove between vane group and projection (6), also can move to corresponding distance to side column blade (10), unlatching mouth (5) and side column (3) on the side column blade (10) are cooperated, thereby open lamina idle-run lock.
Claims (2)
1. lamina idle-run lock, comprise lock housing, lock gall, lock core, blade groove, blade, spring and side column, it is characterized in that: establish lock gall is divided into anterior lock core and post lock core two parts, be provided with the pellet shot from a slingshot hole by locking of anterior lock core, be provided with hoodle and lock pellet shot from a slingshot in the hole, the projection of two correspondences is set in the lock core blade groove, place respectively in the blade groove with the key blade of key interaction and with the side column blade of side column interaction be one group vane group, two corresponding limits of blade are provided with the groove and the projection of cooperation, and key blade can not compress the side column blade on the direction perpendicular to side column.
2. a kind of lamina idle-run lock according to claim 1 is characterized in that: when two groups of vane group are in same blade groove, be provided with the groove and the projection of cooperation between the key blade.
