Description
Technical field
The utility model relates to latch mechanism technical fields, and in particular to a kind of cabinet lock locked from latch tongue.
Background technique
Occur a variety of electronics bins using safety cabinet as representative, the crucial skill of these electronics bin products currently on the market
Art is mainly reflected on bin latch mechanism.And electronics bin latch mechanism in the market has two classes: using one is electronics bin
Electromechanical integration bin latch mechanism, another kind are the purely mechanic bin latch mechanisms that traditional insurance cabinet uses.Electronics bin latch mechanism
Usually by the flexible of an electromagnet or motor control locking bar, to achieve the purpose that switch cabinet door.Traditional insurance cabinet leans on machine
Tool key adds manual cipher switch bin latch mechanism.There are two common ground for above two safe cabinet latch mechanism: first is that must turn
Dynamic handle could lock；Second is that emergent unlocking mode is all to be unlocked with mechanical key.Both the above safe cabinet latch mechanism exists
Two big hidden danger: first is that all existing at closing time, it is possible to a possibility that forgetting swing handle locking；Second is that can by external force or
Illegal open is realized by technological means such as skeleton keys.It can be seen that both the above safe cabinet lock mechanism design does not conform to very much
Reason, there are very big security risks.
Utility model content
The purpose of this utility model is that in view of the above deficiencies, proposing one kind can be realized Multiple locking point interlocking lock, is improved
The cabinet lock of security level.
The utility model specifically adopts the following technical scheme that
A kind of cabinet lock locked from latch tongue, including electronic control unit, mechanical linkage which controls and electromechanical transformation mechanism, machine
Tool linkage mechanism is set in the cabinet door of bin, and the mechanical linkage which controls include door handle, upper locking bolt, lower locking bolt and side chain bolt
Group, door handle are flexibly connected locking bolt upper connecting rod, locking bolt lower link and locking bolt tranverse connecting rod, locking bolt upper connecting rod, locking bolt lower link and lock
Bolt tranverse connecting rod respectively drives the flexible of locking bolt, lower locking bolt and side chain bolt group, and one section of ear mount, cabinet are stretched out in the side of locking bolt lower link
The bottom plate of door is equipped with the limit hole of perforation bottom plate, is equipped with limit film mandril in limit hole, the top of limit film mandril is connected with limit
Bit slice, limit film and ear mount, which are engaged by clamping, drives the linkage of locking bolt upper connecting rod, locking bolt lower link and locking bolt tranverse connecting rod.
Preferably, the cabinet lock locked from latch tongue further includes preventing universal key unlocking mechanism, which includes lock
Head is equipped at tapered end and limits its second electromagnet freely rotated, is connected with swing arm on tapered end, swing arm is L-shaped, and the end of swing arm is set
There is the first magnet.
Preferably, the electronic control unit includes emergency power supply, the anti-unlocking control panel of outer power-up wake-up and indicates user's body
The TM card of part, after the reading of TM card is verified, the second electromagnetic actuation can use mechanical key rotational lock head at this time, make swing arm
The first electromagnet is stirred, its actuation is made, then swing handle can normal door.
Preferably, the side chain bolt group includes three locking bolts, and three locking bolts are fixed on same vertical-shaped steel plate, the horizontal company of locking bolt
Bar controls moving synchronously for three locking bolts by controlling the movement of vertical-shaped steel plate.
The utility model has the following beneficial effects:
When at closing time, after cabinet door is aligned with doorframe, limit film mandril opens limit film, separate its limit film with ear mount,
Position-limiting action disappears, and locking bolt lower link, locking bolt upper connecting rod, locking bolt tranverse connecting rod and door handle are completed locking, resetted, and cabinet door is lockked；
Avoid that there is a situation where forget locker door；
When the openable panel of cabinet lock breaks down, connection emergency power supply wakes up emergent unlocking control panel, needs to meet an urgent need and open
When lock, TM is stuck in be verified on TM card read head after, the second electromagnetic actuation, at this time can use mechanical key rotational lock head, make
The first electromagnet is stirred in swing arm makes its actuation, and then swing handle can normal door；TM card only passes through anti-master key first
The electronically validating of spoon unlocking control panel, can open cabinet door with the use of mechanical key at this time；Otherwise, in other any situations
Under, all it cannot achieve the purpose that illegally to open the door by changing lock core or mechanical skeleton key.
Detailed description of the invention
Fig. 1 is the perspective view of cabinet lock；
Fig. 2 is the electronic control unit control structure block diagram of cabinet lock.
Wherein, 1 is limit film, and 2 be locking bolt lower link, and 3 be limit film mandril, and 4 be locking bolt upper connecting rod, and 5 be the horizontal company of locking bolt
Bar, 6 be door handle, and 7 be the first electromagnet, and 8 be swing arm, and 9 be the second electromagnet, and 10 be tapered end.
Specific embodiment
Specific embodiments of the utility model will be further explained in the following with reference to the drawings and specific embodiments:
As depicted in figs. 1 and 2, a kind of cabinet lock locked from latch tongue, the bin can be safety cabinet etc. to safety level
