Abstract

The utility model relates to a mechanical count lock. The count value of the count device of the lock is added one by the solicitation of the rotating operations of the lock from closing to opening. People can judge whether the lock is opened or not according to that whether the count value is changed, thereby the mechanical count lock has a specific record and display functions on non-authorized opening.

Description

A kind of mechanical count lock

Technical field

The utility model relates to mechanical count lock technology field, refers in particular to a kind of structure-improved that locking/unlatching number of times count of mechanical counting device to lock that embed in lockset.

Background technology

Mechanical counting device in the mechanical count lock utilizes lock bridge or the rectilinear motion of latch mechanism between unlatching and two state transformations of locking to cause once counting usually.When mechanical lock changes to the process of locking states from opening, comprise when rotatablely moving,, also can be used to cause the once counting of mechanical counting device by the transmission mechanism of suitable design.

Summary of the invention

The utility model, the purpose of a kind of mechanical count lock are to utilize lock core to rotatablely move to cause the transmission mechanism that mechanical counting device is once counted system for the mechanical count lock provides a kind of.This mechanism is simple and practical, and reliable in action to the change of conventional lock cylinders seldom, is convenient to utilize original production equipment of original conventional lock cylinders to produce.

Content of the present utility model is such: a kind of top of mechanical count lock lock body, and the top of lock core embeds a mechanical counting device; The counting driving lever of this mechanical counting device and the lock core shift lever on the lock core are coupled, when lock core is driven by key turns and when turning to opening from the playback state, lock core shift lever drives the motion of counting driving lever, causes the appropriate authority action in the tool counting device to make count value add one.The reading window of mechanical counting device is positioned at is convenient to the surface of lock body that people observe, as shown in Figure 1.The count value of this mechanical counting device can only cause by the rotation of lock core from the playback state to opening, specify as follows:

1) necessary condition of finishing the lock operation of lock is at latch mechanism the lock bridge bolt-lock to be lived a back key to extract out from lock core.And the necessary condition that key is extracted out from lock core is that lock core is in the playback state.When lock core was in the playback state, return spring was responsible for counting driving lever playback (seeing accompanying drawing 2);

When 2) unblanking, after the key with the lock core coupling inserts lock core,, eject lock bridge with the lock core rotation.In this process, lock core shift lever can drive the motion of counting driving lever.After lock core and lock core shift lever drove the rotation of counting driving lever and reach certain angle, latch mechanism was threaded off lock bridge is upspring, and lock is unlocked, and this moment, lock core was in opening (seeing accompanying drawing 3) with the counting driving lever; Count the mechanism kinematic that driving lever can drive mechanical counter inside simultaneously, cause the count value of mechanical counting device to add one.

3) will make the count value of mechanical counting device add one again, must experience above-mentioned 1), 2) two processes, promptly make the lock locking make lock core playback earlier, and then unblank.

By top 1), 2) and 3) as can be known described, the unlatching number of times of count value and lock is one to one.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is the utility model assembling drawing;

Accompanying drawing 2 is wherein counted driving lever 7 and all is in the playback state with lock core shift lever 8 for the utility model lock core playback state diagram;

Accompanying drawing 3 is the utility model lock core opening figure, wherein counts driving lever 7 and all is in opening with lock core shift lever 8.

Among the figure: 1 lock core, 2 cover plates, 3 lock bridges, 4 mechanical counting devices, 5 reading windows, 6 return springs, 7 counting driving levers, 8 lock core shift levers, 9 lock core stop rods, 10 lock cores

Specific embodiments

The utility model is seen shown in accompanying drawing 1, accompanying drawing 2 and the accompanying drawing 3.

A kind of major part of mechanical count lock comprises lock body 1, lock bridge 3, lock core 10 etc., and they constitute the traditional mechanical lock with normal function, locking and unlatching normally; Above lock core 10 positions, the top of lock body 1, a mechanical counting device 4 is installed.The utility model is installed lock core shift lever 8 in lock core upper end, it and counting driving lever 7 couplings of mechanical counting device 4 are responsible for rotation with lock core 10 and are passed to and counts driving lever 7.When lock core 10 turned to opening (seeing accompanying drawing 3) by playback state (seeing accompanying drawing 2), lock core shift lever 8 drove counting driving lever 7 and moves together, causes the count value of mechanical counting device 4 to add one; Meanwhile, the latch mechanism of bolt-lock lock bridge 3 is threaded off, and lock bridge 3 is upspring, and lock is unlocked.Lock core stop rod 9 continues to rotate forward after being responsible for stoping lock core 10 to arrive opening.

Above-mentioned lock core shift lever 8 is lock core to be rotatablely moved pass to counting driving lever 7 and cause mechanical counting device 4 count values and add one of vital part of one, and it can be pressed into of lock core end face by a Metallic rod and constitute with its friction tight hole.This solution can utilize general traditional mechanical lock to be the basis, only needs to process an installing hole at it towards the end face in the lock and gets final product.

There is a cover plate 2 top, counting device chamber of lock body 1, is responsible for protection mechanical counting device 4.Simultaneously, open the fitting operation that cover plate 2 can make things convenient for mechanical counting device 4 again.

The counting device chamber has a reading window 5 (seeing accompanying drawing 1), the count value of observing mechanical counting device 4 for people by this window one of towards two surfaces of lock body 1 maximum.

The utility model, promptly a kind of mechanical count lock, the locking process prescription as follows:

Lock core can be and stays key-type or the non-key-type that stays.When lock core when staying the key-type lock core, depress lock bridge 3 earlier and make the latch mechanism locking, then with key rotation lock core to the playback position, extract key out lock core.When lock core is non-when staying the key-type lock core, depress lock bridge 3 the latch mechanism locking is got final product.As long as lock core is in the playback position, key just can be extracted out from lock core, and whether locking has nothing to do with locking.

When lock core was in the playback position, when promptly lock core 10 was in the playback position with lock core shift lever 8, the return spring 6 in the mechanical counting device 4 can be with 7 playback (seeing accompanying drawing 2) of counting driving lever.At this moment, the count value in the mechanical counting device 4 can remain unchanged.

Count value in the mechanical counting device 4 can be observed by reading window 5, and Shi Suozhe only need write down the count value behind the lock locking, and this count value and the preceding count value of unblanking his next time are compared, if change, then this once was unlocked after being locked in his locking last time.

The embodiment of the above only is a preferable embodiment of the present utility model, is not to limit practical range of the present utility model with this, so all equivalences of doing according to the structure and the principle of the utility model change, all should be covered by in the protection domain of the present utility model.
