Description

Passive padlock

Technical Field

The utility model relates to a tool to lock especially relates to a passive padlock.

Background

1. Background of the related art

At present, particularly in the telecommunication industry, in order to prevent outdoor power distribution base stations from being damaged manually, each base station is provided with a padlock for protection, but the existing padlocks in the market generally only have a lock opening and closing function and do not have a lock management function; in other words, who locks the base station open, when it is open, and when it is closed, are difficult to manage; even if some workers leave the duty and lose or take away the key, the potential safety hazard exists between the workers and a base station managed by the workers, and if the follow-up base station is artificially damaged or articles in the base station are lost, the responsibilities are difficult to be clarified, so that unnecessary economic loss is caused, and therefore, the development of a padlock with a management function is very necessary;

2. description of the prior art related to the present invention

A. Most of the existing passive padlocks in the current market can authorize a user to unlock the padlock and can record the unlocking and locking records of the user, but sometimes subordinates can make the subordinates conveniently enter and exit a base station managed by the subordinates at any time, and then can make a fake to a passive key and send a fake signal to a headquarter manager; after the manager authorizes the lock on a certain day to be successfully unlocked, the lock is not actually locked when the manager finishes the lock closing, but the manager sends a signal that the lock is closed to the headquarter manager, and the manager at the headquarter has no way to monitor whether the padlock is really locked or not in real time, so that the manager does not need to authorize the lock through the headquarter when entering the base station next time and can enter the base station at any time, and obviously, the illegal practice of the manager is not wanted by a higher management layer, so that the management is very unfavorable, and the significance of a passive padlock is lost;

B. most of the existing passive padlocks in the current market have no mechanical emergency unlocking function, and some passive padlocks are not disposable even if some passive padlocks are available, so that the mode has a lot of problems;

(1) if the mechanical emergency unlocking is not available, once the electronic key fails to unlock, the padlock can be destroyed to unlock, so that economic loss is caused;

(2) if the mechanical emergency unlocking is not disposable; when a superior manager allocates a mechanical emergency key to subordinate personnel, the subordinate personnel can more conveniently and quickly facilitate subsequent work, and directly copy one mechanical emergency key, so that the subordinate personnel does not need to unlock the base station through the authorization of the manager when entering and exiting the base station for work, and can open and close the lock at any time, thereby losing the management of the manager on the subordinate personnel and the significance of the existence of a padlock;

C. most of traditional passive locks are driven by electromagnets, the electromagnets are easily attracted and opened by strong magnets as drives, and the safety is poor;

D. most of traditional passive padlocks are unlocked by rotating the passive key by 90-180 degrees after the passive key is inserted into a lock body chip and is successfully identified;

E. most of the traditional passive padlocks are waterproof, so that the lock body is easy to lose effectiveness after water drops or outdoor rainforest lock bodies are suffered;

F. when traditional passive padlock adopts the motor as clutch drive electronic lock, its structure of ubiquitous is complicated, leads to the power consumptive height of motor because of structural problem, poor stability, and the life-span is short, the scheduling problem.

As shown in fig. 1-3, the working principle of the present invention is as follows:

1. and (3) locking principle:

the lock beam 12 is pressed down into the lock body 11, then the electronic key 2 is inserted downwards to match signals, once the signals are successfully matched, the motor 18 rotates 90 degrees anticlockwise, at the moment, the fixture block spring 16 pushes the left fixture block 14 and the right fixture block 15 outwards to clamp the lock beam 12, and the electrode spring 16 is separated from the right fixture block 15; (remark: the electrode spring 16 and the right clamping block 15 of the padlock are separated only in the locked state) the circuit board of the lock body 11 transmits a signal to the electronic key 2 after detecting that the lock is closed, at the moment, the LED display screen 23 of the electronic key 2 displays that the lock is successfully closed, the lock closing signal transmits the signal to the mobile phone APP through the Bluetooth module 26, and then the mobile phone APP transmits the signal to the cloud background for storage and management; the transmitted signals comprise signals (who closes the lock, when to close the lock, and the like) so as to achieve the function of background management;

2. explanation of unlocking principle:

the electronic key 2 is inserted for signal matching, after the matching is successful, the motor 18 rotates clockwise to drive the motor cam 19 to rotate, the motor cam 19 rotates 90 degrees, the left fixture block 14 and the right fixture block 15 retract inwards under the action of the motor cam 19, the left fixture block 14 and the right fixture block 15 are separated from the lock beam 12, the lock beam 12 is ejected out under the elastic force of the spring 2, the electrode spring 16 is contacted with the right fixture block 15, (remark: the contact of the electrode spring 16 and the right fixture block 15 represents unlocking), the circuit board of the lock body 11 transmits an unlocking signal to the electronic key 2, and at the moment, the key LED display screen 23 displays that the unlocking is successful; the unlocking signal is transmitted to the mobile phone APP through the Bluetooth module 26, and then transmitted to the cloud background for storage and management; the transmitted signals comprise signals (who unlocks, when to unlock and the like) so as to achieve the function of background management;

3. description of mechanical unlocking:

as shown in fig. 7-11, when the electronic key 2 fails to unlock the lock, the mechanical emergency key 3 can be used to unlock the lock, but the mechanical emergency lock 3 can be unlocked only once, and the padlock fails after being unlocked once, and the administrator of the unit in which the lock core of the padlock is required to be reset to use the lock core again; after an emergency key 3 of an ordinary worker is inserted into the lock cylinder 140, the 1# -8# sheet arranging and separating sheet arranging groove 1 can only be driven, once the lock cylinder 140 is rotated by 90 degrees clockwise, the 9# -10# sheet arranging groove is clamped by the sheet arranging groove 2, the lock cylinder 140 of the worker cannot be reset at the moment, the padlock is always in an unlocking state and cannot be closed, the left clamping block 14 and the right clamping block 15 are clamped by the lock cylinder cam 130, the padlock fails, and the worker needs to take back to reset the lock cylinder 140 to use;

4. explanation of the principle of padlock repair and reset;

description of the principle of lock cylinder reset: the difference between the reset key 4 and the emergency key 3 is: the reset key 4 has two teeth 9# and 10# more than the emergency key 3, and the tooth profiles of 1# to 8# are completely the same; when returning to the factory for resetting, inserting the corresponding reset key 4 into the lock cylinder, wherein the reset key 4 can drive all the pieces arranged in the number 1# -10#, after rotating anticlockwise for 90 degrees, the number 1# -8# pieces are re-inserted into the piece arranging groove 1601 of the piece arranging block 160, pulling out the reset key 4, and at the moment, the left clamping block 14 and the right clamping block 15 are not clamped by the lock core cam 130, so that the left clamping block 14 and the right clamping block 15 are ejected by the clamping block spring 16 again, and the lock closing function of the padlock is restored again;

the above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
