Description
Technical field
The utility model relates to a kind of lockset, relates in particular to the lock head structure in the lockset.
Background technology
The lock structure that uses generally includes lock head structure at present, form by housing and lock core, lock core is cylindric, pellet shot from a slingshot, card key mechanism are set between the fitting face of lock core and housing, pellet shot from a slingshot, card key are cylindric and arrange along axis in couples, because pellet shot from a slingshot, card bond distance weak point differ, stop the rotation of lock core with respect to housing, only under the state that inserts key, each tie point to pellet shot from a slingshot, card key all overlaps with the fitting face of housing with lock core, lock core can rotate with respect to housing, and blocking mechanism is opened.This structure lockset has been continued to use for many years, and the version of its key is comparatively dull, and its pellet shot from a slingshot, card bond structure misplace easily.
Summary of the invention
The complicated and diversified anti-theft lock end of version that the purpose of this utility model is to provide a kind of sound construction, uses stable and key.
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-theft lock end, comprise housing, be arranged at the cylindric lock core in the housing rotationally, and place between the fitting face of housing and lock core, be used to the pellet shot from a slingshot that stops housing and lock core to rotate mutually, card key mechanism, wherein lock core comprises cylindric internal cylinder and is sleeved on the outer cylindrical shape outer lock core of internal cylinder, the external surface of internal cylinder some the belt grooves with axis normal that be arranged in parallel, be symmetrical arranged a pair of arc slide and a slide stage clip in every belt groove, the two ends of slide stage clip are connected with the tail end of a pair of arc slide respectively, two front end opposite position keeps certain interval, and the symmetric position of the outer rim of every pair of arc slide is provided with a keyway respectively; Described pellet shot from a slingshot, card key mechanism comprise two bar shaped card keys and some to pellet shot from a slingshot, two bar shaped card keys and axis are set in parallel in the chute of outer lock core both sides, inner walls and chute relevant position are provided with card key groove, pellet shot from a slingshot is arranged at the card key groove in the housing, and the movable end of pellet shot from a slingshot is crimped on the card key.
Adopt said structure, changed the structure that pellet shot from a slingshot, card key are provided with in pairs in the prior art, two bar shaped card keys and axis are set in parallel between the fitting face of outer lock core and housing, structure is more firm, the card key is difficult for dislocation, cooperating the key cross section of this structure lock is that tooth is established on arc and both sides, and version is more various.
