Description
Technical field
The utility model relates to a kind of lockset, and a kind of anti-blade spring lock of dialling of offset that can prevent to dial sled specifically is provided.
Background technology
At present, on the market and daily cylinder lock, mainly form by lock body, lock core, pellet shot from a slingshot and pellet shot from a slingshot spring, each is equipped with a cylinder-shaped marble to 3-6 pellet shot from a slingshot hole and every hole should be arranged in other lock bodies and the lock core, under locking state, pellet shot from a slingshot is under spring action in the pellet shot from a slingshot hole in the lock body, and pellet shot from a slingshot is understood some pellet shot from a slingshot hole that falls into the lock core correspondence voluntarily, makes lock core to rotate in lock body.When the key of correspondence stretched into lock core, each pellet shot from a slingshot in the lock core all top all withdrawed from the interior pellet shot from a slingshot of lock body to the upper end from lock core, at this moment reverse key, and lock core is rotated in lock body by executing agency, the cylinder lock of locking can be opened.Just because of this structure of cylinder lock itself, make this cylinder lock not use corresponding key also can open this cylinder lock, as so-called MASTERKRY, a kind of antitheft sylinder " CN90212726.8 " that later stage announces, though can avoid the unlatching of MASTERKRY, can't avoid some technical means to open lock core.
Summary of the invention
The utility model is at above deficiency, setting by the biasing lock core, make pellet shot from a slingshot length identical with the length of the acting surface that arrives key, except that original key, reach and do not give Space, and carry out function synchronously by what be installed on blade on the lock core and pellet shot from a slingshot and axis, open to prevent that dialling in the technological means from prying open, thereby remedy the deficiencies in the prior art, provide a kind of and can only just can open, the anti-blade spring lock of dialling of offset of high safety performance with the key that former lock is worn.
The technical scheme that its technical problem that solves the utility model adopts is:
The anti-blade spring lock of dialling of a kind of offset, comprise guide pillar, lock core, lock tube, key, spring, pellet shot from a slingshot and blade, described lock tube outer wall top is provided with several vertical spring eyes, in spring eye, be provided with spring, the centre position, below of lock core is provided with keyhole, described keyhole top is provided with and corresponding pellet shot from a slingshot hole, lock tube upper spring hole, is provided with pellet shot from a slingshot in the pellet shot from a slingshot hole;
Described lock tube inwall both sides are provided with the deep-slotted chip breaker that parallels with the lock tube center, described lock gall is provided with blade groove, described lock core is provided with corresponding grooves with the corresponding position of deep-slotted chip breaker, lock tube both sides, described groove both sides are provided with cross through hole entad, in the described cross through hole return spring is set, be provided with a pair of blade in the described blade groove, described every pair of blade end joint is provided with small pressure spring, described return spring two ends are pressed on respectively on the lock side, behind the plug-in mounting key, the tartar of both sides, key below promotes blade, axis being fallen in the described horizontal groove of blade extreme lower position, pellet shot from a slingshot is fallen in the shell hole that falls of face correspondence on the key synchronously in addition the principle in space. lock core can rotate; When transfering to key, the blade biasing, axis is stuck in the deep-slotted chip breaker of lock tube under the effect of return spring, makes lock core stuck, and lock core can not rotate.
Described key and keyhole match, described key is the open circles column type, and both sides are provided with the tartar of outside protrusion below hollow cylinder, are provided with shell hole with the pairing position of pellet shot from a slingshot above the hollow cylinder of key, and the described axis of guide is arranged in the keyhole, described hollow cylinder on the key is sleeved on the guide pillar, when key inserted keyhole, the pellet shot from a slingshot that withstands the axis of guide was supportted height, and the pellet shot from a slingshot other end produces upwards active force, the compression spring snaps in spring eye; When key is inserted into correspondence position, pellet shot from a slingshot falls into the shell hole that falls on the key under the active force of spring, realizes the rotation of lock core.
The length of described pellet shot from a slingshot is the distance of pellet shot from a slingshot hole upper surface to guide pillar, makes the lock core part of unblanking not have unnecessary a utilized space.
Described lock tube top is provided with locating hole, and described lock core top is provided with locating slot, makes the lock core turned position be positioned at preset distance.
The anti-beneficial effect of dialling blade spring lock of a kind of offset of the present utility model is:
1, by the design of pellet shot from a slingshot length, make lock core unblank partly do not have unnecessary utilized space, have only by the novel key of this realization and could open;
2, the setting by pellet shot from a slingshot, blade and axis reaches the effect of double locking lock core, thereby can effectively stop dialling to pry open and open in the technological means;
