Description

The electronic warning and anti-theft lock

Technical field

The utility model relates to a kind of electronic warning and anti-theft lock.

Background technology

Known lockset generally is made up of the lock body of band pellet shot from a slingshot and the lock core in the lock body, and key is gone up the top pellet shot from a slingshot after inserting lock core, key, and lock core rotates thereupon, makes the lock core locating slot not locked by pellet shot from a slingshot, and lock is opened.Because this lock does not almost have sound when opening, minority lawless person utilizes these characteristics to make a kind of so-called MASTERKRY, to reach the purpose of burglary under the situation that Nobody Knows, that have even peddle this key to reap staggering profits, greatly endanger the people's interests, seriously upset social peacefulness.

The utility model content

The purpose of this utility model is to provide a kind of electronic warning and anti-theft lock, can be overlapped the defective of opening arbitrarily by the lawless person to solve present lock.

This alarm anti-theft lock that the utility model provides, comprise above pellet shot from a slingshot hole and the pellet shot from a slingshot of a circle that lock body and this lock body have, also comprise a gauge tap, one alarm, gauge tap control alarm, gauge tap has a ring bodies, the contact that at least one pair of can make alarm circuit be communicated with, wherein a contact is flexible contact, be contained in the ring bodies inner ring, another contact is a spring contact, be contained on the lock body, ring bodies is enclosed within outside the tail circle pellet shot from a slingshot hole of lock body, and described two contacts are facing to the pellet shot from a slingshot hole, spring contact links to each other the connection alarm when making wherein the last top of the super distance of pellet shot from a slingshot with flexible contact.

Operating principle of the present utility model is: when non-private key inserts, if nipper is lower than private key then is inoperative, when being higher than private key, last top pellet shot from a slingshot causes two contacts of gauge tap to be communicated with, and alarm is powered alarm, send the back row robber person that reports to the police and to proceed lock set, interrupt follow-up operation thus, effectively play antitheft effect, therefore the utlity model has good theftproof performance.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Specific embodiments

Fig. 1 has reflected concrete structure of the present utility model, and as can be seen from the figure the utility model still has a few pellet shot from a slingshot holes 11 and the pellet shot from a slingshot 12 on lock body 1 and the lock body 1, also has a gauge tap 2 and an alarm 3, and gauge tap 2 is used to control alarm 3.Alarm 3 can adopt common alarm on sale on the market, as the CK-A rob-resistant alarm of Zhongnan Radio Factory's production.Gauge tap 2 has a ring bodies 21, and has a pair of contact (22,23) that can make alarm 3 get electric alarm at least, one of them contact is flexible contact 22, radially be installed in ring bodies 21 inner rings, another contact is a spring contact 23, is contained on the lock body 1, and ring bodies 21 is enclosed within on the lock body 1 and encloses outside the pellet shot from a slingshot hole 11 by one of tail end, flexible contact 22 is facing to pellet shot from a slingshot hole 11, and spring contact 23 is between flexible contact 22 and pellet shot from a slingshot hole 11.The utility model has adopted three pairs of contacts that are connected with alarm, is mainly used in cross key, to improve reliability.When key inserts lock core, last top pellet shot from a slingshot, if private key, its tooth depth (nipper) makes pellet shot from a slingshot rise in normal range (NR), pellet shot from a slingshot pushes up less than spring contact, the seat of rotational lock core, lock is normally opened.If not private key, its tooth (nipper) can be more high or low than private key, when being higher than private key, the top can surpass scope spring contact is communicated with flexible contact on the pellet shot from a slingshot, thereby make alarm get electric alarm, the thief dare not continue lock set, and cuts off operation.If be lower than private key, then lock core can not rotate, and lock can't be opened, and plays the alarming anti-theft effect thus effectively.
