The specific embodiment
A kind of lockset is stolen the dead technology that undoes the lock, and is extremely shown in Figure 5 as Fig. 1.Form by lock core 1, lock core cover 2, special-shaped pellet shot from a slingshot hole 3, retaining borehole jack 4, suicide pellet shot from a slingshot 5 and inclined to one side power spring 6.Lock core is located in the lock core cover, and key groove hole 7 is located at the lock core front end.As depicted in figs. 1 and 2, lock core (the radially rotation in lock core cover or axial in push away and outside draw etc.) action is connected or touches dead bolt, and influence dead bolt move preceding design one section at The backlash of lock core---neutral gear 8.Lock core action is during through neutral gear, at lock core cover inwall, during the lock core action its one deck pellet shot from a slingshot must on route, set up one group of special-shaped marble hole, in fill out (hiding) T type suicide pellet shot from a slingshot.This setting only allows lock core that key therefrom the cooperates pellet shot from a slingshot group of committing suiside to weather, otherwise, suicide pellet shot from a slingshot group can be pushed one deck pellet shot from a slingshot 10 and enter lock core marble hole 11 before the lock core action influence the dead bolt action by force, implements suicide coak at lock core and lock core inner room.Only advance not move back in the design of suicide pellet shot from a slingshot, this locking function key also can't be removed.
As shown in Figure 3, described lock body is normally opened, it must be the lock core that has key therefrom the to cooperate pellet shot from a slingshot group of committing suiside to weather, because the gap of two layers of pellet shot from a slingshot 12 of lock core one deck pellet shot from a slingshot and lock core cover this moment is on the adjacent interfaces of lock core and lock core cover just, promptly all pellet shot from a slingshot holes of lock core are in by one deck pellet shot from a slingshot and fill up state.Suicide pellet shot from a slingshot group key tooth the holding of can't contending with to one deck pellet shot from a slingshot.Locked can't the enforcement of committing suiside.Described special-shaped pellet shot from a slingshot hole is up big and down small type, and the aperture, bottom must prevent lock core through out-of-date less than the diameter of lock core one deck pellet shot from a slingshot, exercise on one deck pellet shot from a slingshot the key mistake pull out cause locked.Abnormity pellet shot from a slingshot hole top adds a retaining borehole jack, finally make special-shaped pellet shot from a slingshot hole be two broad in the middle little " in " font.
In a single day lockset meets with unnormal unlocking, promptly during technical unlocking.Need stir pellet shot from a slingshot one by one and seek " cooperation ", " cooperation " is in case finish, drive external force onset at any time, the rotation of drive lock core, as shown in Figure 4, this moment, lock core marble did not hold owing to there being key therefrom to support, and the suicide pellet shot from a slingshot group that inclined to one side power spring holds can be before the lock core action influences the dead bolt action, push one deck pellet shot from a slingshot by force and enter lock core marble hole, implement suicide coak at lock core and lock core inner room.
Described suicide coak is meant in the design of suicide pellet shot from a slingshot can only advance and can not move back.
Described suicide pellet shot from a slingshot is up big and down small T stage scalariform.Constantly hide and overlap in the special-shaped pellet shot from a slingshot hole, and retrodeviate under the effect that holds of power spring, be in the first-degree combat readiness state constantly at it at lock core.All be engaged in the lower end of retaining borehole jack on its major part, the cooperation degree of depth should be differential less than the length of lock core one deck pellet shot from a slingshot.As shown in Figure 6, even when lock core one deck pellet shot from a slingshot is designed to maximum size, suicide pellet shot from a slingshot major part still can be descending be deviate from the retaining borehole jack, and lock core is implemented coak.Microcephaly's design of T type pellet shot from a slingshot bottom is for bringing into play its amount of swinging to greatest extent.In a single day T type pellet shot from a slingshot major part deviates from the retaining borehole jack, and that fearness of its microcephaly has slight wallowing motion, and T type pellet shot from a slingshot major part does not think to return the retaining borehole jack yet again.
As shown in Figure 5, described inclined to one side power spring must run-off the straight when guaranteeing that T type pellet shot from a slingshot is deviate from the retaining borehole jack, and it is drawn out an angle of inclination with the terminal coil that contacts of T type pellet shot from a slingshot.Bearing force is that deflection is released.
In a word, the present invention is applicable to various senior theftproof locks, is that the performance of senior theftproof lock the best is promised to undertake bottom line.Realized antitheft upgrading with comparatively simple design and lower cost of manufacture.The theftproof performance of lockset can be performed to the limit.And fundamentally restrain technical unlocking.Any robber person all can't be rethought resemble to steal and open this lock.
