Abstract
The present invention relates to a kind of pick-proof fold latch, including tapered end, the strip folded piece be made up of some sections of rigid materials head and the tail are articulated and connected successively to be formed and fold chain, described one end folding chain is provided with tapered end, and the other end of described folding chain is provided with the plug matching with lockhole on tapered end.Because this fold latch only need to arrange jack in tapered end cylinder, periphery does not have gap, and therefore, robber has no exploits, and strengthens intensity, increases the difficulty of robber's picking lock, improves the overall theftproof performance of lock body.
Description
Technical field
The present invention relates to a kind of portable portable lockset, specifically a kind of pick-proof fold latch.
Background technology
Fold latch due to have the advantages that removable, foldable, be convenient for carrying, therefore suffer from the welcome of people.Fold latch
Structure generally includes the tapered end being made up of lock core, stop and lock housing, the strip folded piece being made up of some sections of rigid materials, institute
State folded piece head and the tail successively be articulated and connected formation fold chain, one end of described folding chain is provided with tapered end reservoir body, described
Tapered end is fixedly installed in tapered end reservoir body, and the described other end folding chain is provided with and is matched with lockhole on tapered end
Plug, plug completes to open the function with locking by controlling stop after inserting lockhole.Existing fold latch is from tapered end side
Face insertion, the side of lock housing leaves gap so that stealer holds easy-to-use tool carries out picking lock from this position, unreliable.
Content of the invention
It is an object of the invention in order to overcome the deficiencies in the prior art to provide a kind of relatively reliable fold latch.
To achieve these goals, the technical solution used in the present invention is：A kind of pick-proof fold latch, including by lock core, lock
The tapered end of lock and lock housing composition, the strip folded piece being made up of some sections of rigid materials, described lock core is rotatably arranged in
In lock housing, described folded piece head and the tail are articulated and connected successively to be formed and fold chain, and one end of described folding chain is provided with tapered end and holds
Cavity, described tapered end is fixedly installed in tapered end reservoir body, and the described other end folding chain is provided with is locked with tapered end
The plug that matches in hole it is characterised in that：Described lockhole is arranged on perpendicular with lock core axis end face in tapered end reservoir body,
Lock core tail end is relative with described lockhole, and key hole is arranged on the other end, and stop is arranged on lock core tail end and lock in lock housing inner chamber
Part between hole, described stop is linked with lock core and radially slides, and plug ends are provided with the less cervical region of diameter, described stop
The position relative with lockhole has a latch aperture matching with plug, described latch aperture side be provided with and be connected and with plug cervical region
The breach matching, consists of the relative position rotating the lock core driving stop described latch aperture of change and breach and lockhole and unlocks and close
Lock cooperation.
Using such scheme, because lock housing and tapered end reservoir body only need to arrange jack in cylinder, periphery does not have gap, because
This, robber has no exploits, and strengthens intensity, increases the difficulty of robber's picking lock, improves the overall theftproof performance of lock body.
