Description

A kind of Assembled lock

Technical field: the utility model relates to a kind of lockset.

Background technology: lock is one of topmost security personnel's apparatus in the household articles, and the theftproof performance, the reduction mutual opening rate that therefore how to improve lockset are the major subjects of lockmaking industry research.Each diverse structure of tapered end form that constitutes the lockset core parts is ever-changing, as vane type and two kinds of form of structure of cylinder type.Vane type tapered end good rigidly long service life, the simple cost of cylinder type lock head structure is low, each have their own strong point, but the tapered end mutual opening rate height of single structure, grope very capacity repeatedly through theft and grasp rule by pirate of the open, reduce the mutual opening rate lock core that must extend and increase blade or pellet shot from a slingshot number, do very uneconomically like this, and effect is also undesirable.

Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art and provides that a kind of theftproof performance is good, mutual opening rate is low, and can prevent effectively that various robber's lock tools from inserting and opening the blade marble Assembled lock of lockset.

For achieving the above object, the technical solution that the utility model adopts is as follows: this Assembled lock comprises lock housing, lock core and the latch members of being made up of pellet shot from a slingshot, pellet shot from a slingshot back-moving spring, spring seat pin, have the keyhole that axially runs through on the lock core, the pellet shot from a slingshot hole of placing pellet shot from a slingshot is no less than two and vertical keyhole and arranges vertically, it is characterized in that: described keyhole shape of cross section is non-straight trough abnormity, roughly be serpentine, a side deep-slotted chip breaker of serpentine keyhole is in the lock core body surface; The lock core body surface also is provided with the arc groove that is arranged in parallel vertically more than two, described arc groove communicates with the end that the serpentine keyhole is in the lock core body surface, in being provided with between lock housing and the lock core with fastening outer and the core retainer plate that lock housing is rotatably assorted of lock core, being mounted with in the arc groove of formation sealing cavity volume can be rotating in arc groove, the outer arc diverse location is provided with the arc shaped blade and the leaf spring of breach, blade one end stretches in the keyhole, the other end and leaf spring join, have the slot mesh groove that is communicated with arc groove on the core retainer plate on the position of corresponding arc groove vertically, be provided with the movable locking side column that cooperates in the slot mesh groove, under locking states, the corresponding slot mesh groove of lock-shell lining has a latch recess on the position vertically, be provided with locking side column in the space that slot mesh groove and latch recess are formed, locking side column can be slided between lock housing and core retainer plate in described space.

With the supporting key of tapered end, comprise the shank of the key, key shoulder and spoon sheet, the spoon sheet cross section of described key is the serpentine that matches with the keyhole cross section, tartar is arranged on spoon sheet both sides of the edge.

The Assembled lock of said structure, comprise blade and cylinder lock pin assemblies simultaneously, when having only the key that will have two groups of correct key tooth flowers to insert keyhole, be that locking side column is alignd in line with all blade breach, locking side column breaks away from lock housing and slides between core retainer plate and the lock core, when the spring seat pin heads into lock housing by tartar by pellet shot from a slingshot simultaneously, lock core and lock housing could relatively rotate displacement under external force, can improve theftproof performance exponentially and reduce mutual opening rate greatly by the combination of different blades and pellet shot from a slingshot number is set; And the matched key of odd-shaped cross section not only makes the intensity increase of key can prevent effectively further that also various robber's lock tools from inserting and opening lockset.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
