Description

Double cores time-limiting lock

Technical field

The present invention relates to a kind of lockset, especially can limit the double cores time-limiting lock of uncaging time.

Background technology

Current, what general lockset generally adopted is the technology of being unblanked by a lock core control, and uncaging time is unrestricted, and the people with professional unlocking technique is easy to open lockset with the instrument beyond the key, and anti-theft effect is bad.

Summary of the invention

In order to overcome the unrestricted deficiency of monolock core uncaging time, the invention provides a kind of double cores time-limiting lock.This lock adopts twin-core technical limitations unlocking person of prescribing a time limit to open within a certain period of time, has crossed binding hours and has failed to open lockset, then must open again, and freight weight limit is not counted again.This lock can set up the opening time on their own according to different situations by the end user, limits safe class, has complete anti-theft feature.

The technical solution adopted for the present invention to solve the technical problems is: double cores time-limiting lock comprises housing (30), twin-core blocking device, twin-core energising device, timing restraint device (13), timer arrangement (18) and jumping locking device.Power supply (15) is connected with twin-core energising device, timing restraint device (13), timer arrangement (18) by lead (14).Regularly restraint device (13) and timer arrangement (18) are fixed on the motor (12) of prescribing a time limit.

The specific embodiment:

When opening the twin-core blocking device, each lock core is all connected separately and is regularly limited device circuit, and motor is started working in limited time, drives regularly restraint device and timer arrangement and sets and unblank the time limit, set the time limit of unblanking after, motor cuts off the power supply voluntarily and quits work.When unblanking when Zhongdao time limit, timer arrangement is connected and is jumped the locking device circuit once, and jump the lock motor drives and jump locking device and finish and once jump lock, twin-core blocking device homing, must return the lock core original position and unblank again this moment, repeats aforesaid operations, do not limit number of times.

When opening lock core, there is a lock core column to drive the energising contact pilotage in the lock core and stretches out outside the core, connect motor circuit in limited time.

When unblanking, setting prescribes a time limit, regularly restraint device and timer arrangement run-in synchronism under the drive of the motor of prescribing a time limit, and regularly the hot contact of limiter means is connected circuit, and enforcement is regularly.After regularly finishing, outage contact disconnecting circuit also returns under the drive of timer arrangement, implements in limited time.In the process of prescribing a time limit, connect when timer arrangement only finishes in limited time and jump the lock motor circuit once, disconnection then.

On jumping locking device circuit, a gate-controlled switch is arranged, can be made as required and jump lock and do not jump the lock two states.When being made as jumping lock state, under the situation of jumping lock motor energising work, the jumping lock touches the jack-up of dashing forward and jumps the locking device controlling platform, makes the locking turning cylinder break away from the control of lock core cursor, under the effect of spring, automatically replies original position, finishes the jumping lock; Cut off the power supply out-of-work the time jumping the lock motor, jump lock and touch prominent ineffectively, under the control of jumping the lock lifting support, rely on the active force homing of spring.When being made as when not jumping the lock state, jump the lock motor circuit and disconnect all the time, jump locking device and lose the jumping lock function.

Need open successively when opening the twin-core blocking device two lock cores,, when opening first lock core, lock core A cursor drives locking turning cylinder A to external obturator hernia place, afterwards, opens second lock core again, lock core B cursor drives locking turning cylinder B and rotates, locking turning cylinder B promotes the tail end mouth that locking contact B stretches into locking turning cylinder A, promotes locking contact A and stretches into external obturator hernia, and external locking capital in the hole is gone out, connect outside blocking device, rotate outside blocking device and open lockset.Two lock cores are double stem stem, when first lock core is opened, one row lock core column breaks away from the core hole, after rotating to an angle, another row lock core column enters the core hole, and after key was extracted lock core out, it is motionless that first lock core is maintained fixed, and then second lock core of unlatching that use the same method, the twin-core blocking device is in fully opens the back state.

In Fig. 1, when opening lock core, energising contact pilotage 1 is connected motor 12 circuit in limited time, under motor drives, and timing restraint device 13 and timer arrangement 18 synchronization timings, hot contact 16 contacts energising slideways 20 at this moment, regularly restraint device 13 is a "on" position, and timer arrangement 18 is an off-position, after regularly finishing, outage contact 17 is connected energising slideway 20, and regularly limiter is an off-position.Definite time-lag in, connect when timer arrangement 18 finishes in limited time and jump lock motor 2 circuit once, under motor drives, jump 6 liftings of locking device controlling platform once, drive locking turning cylinder A 10 and locking turning cylinder B 4 synchronization liftings once, finish and once jump lock.

In Fig. 2, under lock core A cursor 8 drives, locking turning cylinder 10 forwards external obturator hernia 9 places to, the interior locking contact A 11 of axle this moment aims at external obturator hernia 9, afterwards, and under lock core B cursor 5 drives, locking turning cylinder B 4 promotes locking contact B 7 and enters in locking turning cylinder A 10 end interfaces, promote locking contact A 11 and stretch into external obturator hernia 9, outside the external locking post 22 outstanding holes, be connected in a chain of promotion hole with outside blocking device.

In Fig. 3, when jumping the 2 energising rotations of lock motor, locking device controlling platform 6 is jumped in drive and locking turning cylinder A 10, locking turning cylinder B 4 raise together, realizes jumping and locks.After jumping lock, under the effect of spring, locking turning cylinder A 10 and locking turning cylinder B 4 homings, simultaneously, locking contact A 11 and locking contact B 7 be homing also, and the lock core cursor must be got back to initial position and unblanked again this moment.

In Fig. 4, regularly restraint device is when timing, and hot contact 16 is connected energising slideway 20, is communicated with motor 12 circuit in limited time, implements regularly.Behind hot contact 16 contact timing limiter active card door bolts 24, motor 12 circuit disconnect in limited time, regularly end.Then, contact arms 26 returns under the drive of timer, and the contact 17 contact energising slideways 20 that cut off the power supply this moment return, and motor 12 circuit are off-state in limited time.When outage contact 17 is back to when regularly limiter electrode column 23 contact, connect motor 12 circuit of prescribing a time limit, the repetition above-mentioned steps.Independent mobile active card door bolt 24 also is fixed in regularly limiter electrode column 23 and safe class and limits certain on the energising slideway 20 between the bolt 25, can limit the time limit in limited time, the setting safe class.

In Fig. 5-A-Fig. 5-C, timer arrangement for opening circuit, in the return course that regularly finishes, when slide blocks 28 are switched in sliding pin 27 contacts of energising, is connected and is jumped the lock motor circuit once in timing process.

Utilize the core aufbauprinciple of double cores time-limiting lock, can make different sizes, the difform twin-core structure of prescribing a time limit,, make the lockset of different industries, different purposes in conjunction with the live part of other locksets.
