Abstract

The invention discloses a bent key. The bent key is formed by moveably matching and connecting a key handle and a crawler-type key strip, wherein the crawler-type key strip is formed by moveably matching and connecting a plurality of key sheets; an unlocking marble concave hole is reserved on each key sheet; a first unlocking marble concave hole is reserved on the key handle; the key handle is movably matched and hinged with the key sheets through a first hinge shaft; and each key sheet is movably matched and hinged through a second hinge shaft. The bent key can be used together with a bent keyhole anti-theft lock, so that the difficulty of a stealer unlocking the lock with a universal key is increased and the anti-theft property of the anti-theft lock is improved.

Description

Crooked key

Affiliated technical field

The present invention relates to a kind of key, particularly a kind of crooked key.

Background technology

At present, the keyhole of theftproof lock all is straight on the market, and key also is straight, and the robber is easier to open with master key, designs a kind of crooked keyhole theftproof lock, improves the theftproof lock performance, and needing to use can crooked key unlocking.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of crooked key is provided, be used to open crooked keyhole theftproof lock, improve the theftproof lock performance.

The technical scheme of taking of the present invention is: crooked key, include the key handle, crooked key is connected and composed movingly by key handle and crawler type key bar, crawler type key bar is connected and composed movingly by the multi-disc key piece, key piece is provided with the pellet shot from a slingshot shrinkage pool of unblanking, and key is being provided with the first pellet shot from a slingshot shrinkage pool 11 of unblanking.The key handle is hinged movingly by first jointed shaft and key piece, and first jointed shaft is fixedlyed connected with the key handle, and first jointed shaft and key piece are hinged movingly; Perhaps first jointed shaft and key are hinged movingly, and first jointed shaft is fixedlyed connected with key piece; Each key piece is hinged movingly mutually by second jointed shaft.

During use, crooked key is inserted keyhole, because crooked key is provided with crawler type key bar, crawler type key bar is connected and composed movingly by the multi-disc key piece, therefore crooked key can enter along the keyhole of bending in the lock core, after crooked key enters crooked keyhole, the pellet shot from a slingshot of anti-theft lock core just in time inserts in the pellet shot from a slingshot shrinkage pool of unblanking of crooked each correspondence of key, make the contact position of lock core marble and lock spring just in time be positioned at the contact surface position of lock body and lock core, rotate crooked key lock core is rotated, the part of unblanking of internal cylinder drives the unlocking mechanism rotation can open theftproof lock.

The invention has the beneficial effects as follows: crooked key engage flex keyhole theftproof lock uses, and has increased the robber and has used master key to open the difficulty of theftproof lock, has improved the theftproof performance of theftproof lock.
