Description

Alarming lock

The utility model relates to the lock that a kind of people use always, particularly theftproof lock.

Lock is for the user, avoid theft nothing but, its method is that locking bar is fixed, its two ends that link to each other can not be moved mutually, thereby reach the effect of " pinning ", as long as and the thief manages to break locking bar, perhaps locking bar is pried open, soon at least one end of fixing locking bar is removed just can reach and is made lock lose antitheft effect.Since the present of being locked to has been arranged, the function of lock has only one---and reinforce the object of being locked, it is not opened easily, the history of whole lock is exactly the history of reinforcing, and the firm degree of lock has determined the stolen possibility of locked object spare.In case the greatest weakness of existing lock be the burglar destroyed lock firmly, the locked object spare robber person that can only leave steals, and makes the owner painful.

The purpose of this utility model is exactly in order to address the above problem, and a kind of alarming lock with warning function is provided.

Technical solution of the present utility model:

A kind of alarming lock is characterized in that in lock body the position is provided with the lock core gauge tap near the corresponding lock core, and corresponding dead bolt shift position is provided with the dead bolt gauge tap in the lock body, and lock core gauge tap and dead bolt gauge tap are serially connected on the warning circuit.

Characteristics of the present utility model are that having added a function to lock is warning function; it can tell relevant people that the burglar is arranged here; the increase of this function dare not be committed theft the burglar; escape on hearing the news; the utility model unites two into one electronic warning and lock; the function that makes lock both have reinforcing also has warning function; the protection of these two kinds of functions is arranged; most stealers are beaten a retreat in the face of difficulties; the utility model is contained in simple warning device in the lock body; do not need complicated apparatus, also do not increase what cost, its effect then is very large.

As Fig. 1-5, the utility model in lock body near the corresponding lock core 1 position be provided with lock core gauge tap 2, corresponding dead bolt 3 shift positions are provided with dead bolt gauge tap 4 in the lock body, and lock core gauge tap 2 and dead bolt gauge tap 4 are serially connected on the warning circuit.Lock core gauge tap 2 is as Fig. 1～3, it can be in lock body a side of lock core 1 breech face semicircle protuberance 5 be provided with lock core gauge tap 2, promptly by being connected with its fixed contact 7, and a side of movable contact 6 is connected with spring 8 and is against on the corresponding fulcrum in the lock housing body movable contact 6 of this switch 2 from lock core 1 breech face.Like this, when if lock core 1 rotates, the semicircle protuberance 5 of lock core 1 breech face rotates thereupon, it puts up with elastic force and fixed contact 7 disengagements that the movable contact 6 that promotes lock core gauge tap 2 overcomes spring 8, lock core gauge tap 2 is disconnected, fixed contact 6 is connected with fixed contact 7 under spring 8 restoring force effects again when lock core 1 rotates return, makes lock core switch 2 closures.

In like manner, also lock core gauge tap 2 can be arranged on the sidepiece of lock body internal cylinder 1, only need be provided with control lock core gauge tap 2 protuberances moving, fixed contact at the sidewall correspondence position of lock core 1 and get final product.

Dead bolt gauge tap 4 of the present utility model is arranged in the lock housing body, it can be arranged on the tail end of dead bolt 3, and (dead bolt of such lock all is positioned at the lock housing body, as door lock, drawer-lock etc.), also can be arranged on the entrance point (it is external that the dead bolt of such lock is positioned at lock housing, as padlock, inserted-link type lock etc.) in the lock housing body.Former structure such as Fig. 4, its dead bolt gauge tap 4 is made up of fixed contact 9, movable contact 10, connecting rod 11 and spring 12, movable contact 10 middle parts and connecting rod 11 1 ends are hinged, the baffle plate 13 of connecting rod 11 other ends be positioned at lock body dead bolt 3 tail ends near, the middle part of connecting rod 11 and spring 12 1 ends are hinged, and spring 12 other ends are hinged on the interior corresponding fulcrum of lock housing body.Like this, when dead bolt 3 was open, it just promoted baffle plate 13 and connecting rod 11 1 thereof in the same way in the lock body, moved in the connecting rod 11 just to drive that movable contact 10 moves and fixed contact 9 is connected.Simultaneously, spring 12 makes movable contact 10 and fixed contact 9 keep on-states also with moving in the connecting rod 11 and be partial to another side.

The original state of above-mentioned dead bolt gauge tap 4 is by Artificial Control, as be connected to baffle plate 13 rear portions of connecting rod 11 by pull bar on lock housing body internal cylinder, so just can make dead bolt gauge tap 4 returns by key rotation lock core.

Be positioned at the external lock body of lock housing for dead bolt 3, its dead bolt gauge tap 4 is as Fig. 5, it is by fixed contact 14, movable contact 15 and spring 16 are formed, movable contact 15 and fixed contact 14 are positioned at the import department of the corresponding dead bolt 3 insertion mouths of lock housing body, the middle part of movable contact 15 and spring 16 1 ends are hinged, and spring 16 other ends are connected with the interior corresponding fulcrum of lock housing body.When lock body is pinned in the import of dead bolt 3 insertion lock housing bodies, the front end of dead bolt 3 just promotes elastic force and fixed contact 14 disconnections that movable contact 15 overcomes spring 16 simultaneously, when in case dead bolt 3 leaves the lockhole of lock housing body, movable contact 15 is just connected at the restoring force effect and the fixed contact 14 of spring 16, makes 4 work of dead bolt gauge tap.

For the ordinary bicycle lock, its dead bolt gauge tap 4 as shown in Figure 6, it is made up of fixed contact 17, movable contact 18, spring 19, shank 20 and alignment pin 21, because the dead bolt 3 of ordinary bicycle lock is a bow, the Ying Zaiqi tail end is provided with alignment pin 21, dead bolt gauge tap 4 is positioned at the lock housing body, its shank 20 1 ends link to each other with the middle part of movable contact 18, its other end crook is hooked the alignment pin 21 of dead bolt 3 tail ends when dead bolt 3 lockings, the middle part of movable contact 18 also is connected with spring 19 1 ends simultaneously, and spring 19 other ends are connected with the interior corresponding fulcrum of lock housing body.Like this, when pulling arc dead bolt 3 was in locking-in state, the alignment pin 21 of dead bolt 3 tail ends just spurred shank 20 and together moves forward, and moving of shank 20 just spurs elastic pulling force and fixed contact 17 disconnections that movable contact 18 overcomes spring 19.In case dead bolt 3 leaves lockhole when making lock body be in open mode, the alignment pin 21 of dead bolt 3 tail ends is inoperative, and movable contact 18 and shank 20 thereof move under the restoring force effect of spring 19 backward, movable contact 18 and fixed contact 17 are connected, 4 work of dead bolt gauge tap.

Warning circuit of the present utility model can adopt the simplest existing structure, and it is made up of battery E and buzzer Y, and this circuit also is placed in the lock housing body, and is connected in series with lock core gauge tap 2 and dead bolt gauge tap 4.When lock body normally was in locking-in state, lock core gauge tap 2 was in closure state, and dead bolt gauge tap 4 is in off-state.In case when having the burglar to destroy lock body dead bolt 3 is opened, then dead bolt gauge tap 4 is just by aforementioned course of work closure, thereby makes warning circuit connection work, buzzer Y sends chimes of doom, makes the burglar on hearing the news and escape, and reaches the antitheft purpose of lock body.
