Abstract
The invention discloses a curved spring key comprising a key handle. The curved spring key is formed by connecting the key handle with a spring-type key bar, wherein the spring-type key bar is formed by connecting a key piece and a spring, and the key piece is provided with an unlocking marble concave hole; and the key handle is welded with a connector provided with a countersink, a joint sleeve is connected in the countersink and is fixedly connected with the spring, the key piece is provided with a through hole, and the spring penetrates through the through holes of a plurality of key pieces to be connected with the key pieces. Because the middle of the key piece is connected by the spring to form the key, the curved spring key can curve along a curved keyhole. The curved spring key is matched with a curved keyhole anti-theft lock so as to increase the difficulty for robbers to unlock the anti-theft lock with a master key and improve the anti-theft performance of the anti-theft lock.
Description
Affiliated technical field
The present invention relates to a kind of key, particularly a kind of flexural spring 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 flexural spring 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: the flexural spring key, include the key handle, and the flexural spring key is connected and composed by key handle and spring key bar, and spring key bar is connected and composed by key spare and spring, and key spare is provided with the pellet shot from a slingshot shrinkage pool of unblanking.Key is being welded with connector, and connector is provided with counterbore, is connected with adapter sleeve in the counterbore, and adapter sleeve is fixedlyed connected with spring, and key spare is provided with through hole, and the through hole that spring passes a plurality of key spares is connected with key spare.Because the flexural spring key is to be connected and composed with spring by a plurality of key spares, so the flexural spring key can be along the keyhole bending of bending.
During use, the flexural spring key is inserted keyhole, the flexural spring key can enter along the keyhole of bending in the lock core, after the flexural spring 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 the flexural spring key lock core is rotated, the part of unblanking of internal cylinder drives unlocking mechanism and rotates and can open theftproof lock.
The invention has the beneficial effects as follows: flexural spring 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.
