Abstract
The invention relates to a prying prevention folding lock which comprises a cylinder and a folding chain formed by sequentially connecting strip-shaped folding pieces made of rigid materials end to end in a hinged mode. The cylinder is arranged at one end of the folding chain, and a plug matched with a lock hole in the cylinder is arranged at the other end of the folding chain. Due to the fact that only an inserting hole needs to be formed in the cylindrical face of the cylinder and seams do not exist on the periphery, no gap is left for a thief, strength is increased, the lock prying difficulty of the thief is increased, and the overall anti-theft performance of a lock body is improved.
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 is owing to having advantage that is removable, collapsible, that be convenient for carrying, therefore welcomed by the people.Fold latch structure generally includes the tapered end be made up of lock core, stop and lock housing, the strip folded piece be made up of some sections of rigid materials, described folded piece head and the tail are articulated and connected successively and form folding 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, the other end of described folding chain is provided with the plug matched with lockhole on tapered end, completes the function of unlatching and locking after plug inserts lockhole by controlling stop.Existing fold latch is inserted from tapered end side, and gap is left in the side of lock housing, makes stealer hold easy-to-use tool and carries out picking lock from this position, unreliable.
Summary of the invention
The object of the invention is to provide one fold latch more reliably to overcome the deficiencies in the prior art.
To achieve these goals, the technical solution used in the present invention is: a kind of pick-proof fold latch, comprise by lock core, the tapered end of stop and lock housing composition, the strip folded piece be made up of some sections of rigid materials, described lock core is arranged in lock housing rotationally, described folded piece head and the tail are articulated and connected successively and form folding 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, the other end of described folding chain is provided with the plug matched with lockhole on tapered end, it is characterized in that: described lockhole is arranged in tapered end reservoir body with on the end face of lock core axis perpendicular, lock core tail end is relative with described lockhole, key hole is arranged on the other end, stop is arranged on the part in lock housing inner chamber between lock core tail end and lockhole, described stop and lock core link and radially slide, plug ends is provided with the less neck of diameter, the position that described stop is relative with lockhole has a latch aperture matched with plug, described latch aperture side is provided with and is connected and the breach matched with plug neck, drive stop to change described latch aperture and breach by rotational lock core to form with the relative position of lockhole and unblank to coordinate with locking.
Adopt such scheme, because lock housing and tapered end reservoir body only need arrange jack at 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 theftproof performance of lock body entirety.
Below in conjunction with the drawings and specific embodiments, invention is further described.
