Description

Alarming lock

Technical field

The utility model relates to a kind of burglar alarm, particularly relates to a kind of alarming lock.

Background technology

Existing general lock commonly used adopts key to insert the interior key of keyhole substantially and unblanks, and in order to improve theftproof performance, has done many improvement on the frame for movement of lock.Meanwhile, to locking face, there is application of electronic technology various anti-theft alarm lock to occur again, the theftproof performance of lock is greatly improved.But the alarming lock complex structure that has, difficulty of processing increases, and manufacturing cost improves, and the theftproof lock theftproof performance that also has is unsatisfactory.Therefore, lock is needed constantly improvement and perfect.

The utility model content

The purpose of this utility model be exactly on the technical foundation of existing lock at the deficiency of above-mentioned existence, further improve and perfect, provide a kind of simple in structure, the alarming lock of low cost of manufacture, warning dependable performance.

The scheme that the utility model technical problem solves is: a kind of alarming lock, comprise that lock body, lock core, rotating disk, handle, warning system, key constitute, described lock core is made of motion block and limited block, have several lock bullet grooves on the motion block, spring and lock bullet in playing groove, lock are installed, be provided with in the upper end of motion block and push away post, this pushes away the top Elastic Contact of the top end face and the latch of post; Limited block is provided with slideway, an end Elastic Contact of the upper surface of limited block and spring leaf; The other end of spring leaf is fixed on and triggers on the glomeration, on the triggering glomeration contact is housed; Rotating disk is provided with the shotpin hole, in this shotpin hole spring and latch is installed; A fixed handle of rotating disk, the another side of rotating disk is plectrum fixedly.

Working condition is such, when normally unblanking, key inserts in the keyhole from gathering sill, breach on the lock bullet on the motion block in each bar lock bullet groove point-blank, and form a chute, this moment, the slideway of limited block was aimed at chute, the horizontal sliding key, the chute of motion block moves forward along the slideway of limited block, and the post that pushes away of motion block front end moves forward thereupon, and latch is moved back in rotating disk, after withdrawing from the stop mouth, swing handle, rotating disk rotates thereupon, the fixing plectrum of rotating disk another side is pushed dead bolt aside, finishes the key horizontal sliding and opens the door.

When improper unblanking, the key of any unreserved seating or other unlocking tools insert in the keyhole, all can not make the dislocation breach of respectively locking on the bullet line up a line, can not form chute, motion block can not move forward along the slideway of limited block, as attempt the improper key unlocking of horizontal sliding, motion block can not move forward separately, can only move forward together with limited block, before latch did not fall back on the position as yet, limited block front end face contact spring leaf contacted with the contact, warning circuit is switched on, begin to report to the police, the indicator lamp that is serially connected in the loop is bright, realizes sound and light alarm simultaneously.

On motion block, have 4 locks and play groove, on the every lock bullet opening is arranged all, resetting means is installed on turntable shaft, handle is resetted.

The beneficial effects of the utility model are: lock simple in structure, the key horizontal sliding is unblanked, low cost of manufacture, warning dependable performance.Can realize the lock of sound and light alarm.Be particularly suitable for installing on security door and the safety cabinet.
