Description
Technical field
The present invention relates to the sliding block avoiding mechanism for electronic lock, and using the electronic gate of the sliding block avoiding mechanism
Lock, specifically a kind of sliding block avoiding mechanism and its limited unlocking electronic lock.
Background technology
Door lock is a kind of equipment for door lock is lived, and is generally divided into mechanical, electronic, coded lock etc., some of door locks
For metal cabinet door or control device screen, such cabinet lock is mainly used in opening for the metal cabinet doors such as power distribution cabinet, file cabinet, locker
Close；And the electronic lock for being used for above-mentioned cabinet door generally requires forceful electric power or light current provides unlocking power；According to the mode of its electronic induction
Difference, is divided into electronic password lock, electronic induction lock etc..Existing some intelligent electronic locks used in the industry use dual-coil electromagnetic valve knot
Structure, its operation principle usually breaks movable slider by a magnetic valve, completes work of locking, and another is the electric magnetic valve of normal open.Work as door
After locking is closed, normal open electricity magnetic valve pins mechanical latch always, and in the case where there is electricity, mechanical key is limited, it is desirable to Wu Fakai
Open, only in the event of a loss of power, after normal open electricity magnetic valve is automatically springed open, mechanical key can be opened.But such smart electronicses
The maximum application problem of lock is：After magnetic valve normal open electricity, easily generate heat perishable, when normal open electric magnetic valve bad after, mechanical key is with regard to energy
Open, so as to not reach the limited purpose of mechanical key.
The content of the invention
To overcome above-mentioned deficiency, the purpose of the present invention is to provide a kind of sliding block avoiding mechanism and its limited unlatching to this area
Electronic lock, makes its existing like product structure design of solution not good enough, causes stability not good enough, the technology being further improved is asked
Topic.The purpose is to what is be achieved through the following technical solutions.
A kind of sliding block avoiding mechanism, sliding block one end of the sliding block avoiding mechanism, which is stretched out, avoids pedestal, its structure design main points
It is that motor, screw rod, screw drive block, optoelectronic switch, sliding block, spring are provided with the avoidance pedestal, one end of the sliding block leads to
Cross spring effect and stretch out avoidance pedestal, the other end of sliding block is inserted in one end of spring by spring stack, and the other end of spring is with keeping away
Allow the inwall of pedestal to offset, avoid and sealing ring is provided with the sliding block stretching of pedestal；Motor, screw rod, screw drive block are arranged at cunning
In avoidance pedestal below block and spring, one end of screw rod and the rotary shaft of motor are connected, and screw rod is provided with screw drive block, spiral shell
The slide block slot of sliding block is inserted at the top of bar drive block, and the bottom of screw rod is provided with optoelectronic switch, the bottom correspondence institute of screw drive block
One of optoelectronic switch is stated, optoelectronic switch is connected by circuit with circuit board, indicator lamp respectively.So as to drive spiral shell by motor
Bar is rotated, and then is subjected to displacement the screw drive block on screw rod, so that the displacement stroke of control slide block, or moved with movable slider
It is dynamic；Optoelectronic switch is used to show sliding block avoiding mechanism state in which, or starts corresponding light by the screw drive block of displacement
Electric switch.
The bottom of the screw drive block provided with three optoelectronic switches, three optoelectronic switches be respectively it is limited, mechanical unlock,
Electronics three state instructions of unlocking, the bottom of screw drive block, which offsets, presses one of optoelectronic switch, and the slide block slot of sliding block is set
There are two displacement spaces of screw drive block.When screw drive block is located at the optoelectronic switch of sliding block protruding side, sliding block is due to spiral shell
Bar drive block it is spacing, it is impossible to be moved, now the screw drive block started by press optoelectronic switch；When screw drive block passes through
When screw rod is moved to the optoelectronic switch of centre, sliding block is that contraction can be achieved by external force, and now screw drive block pressing is opened
Optoelectronic switch in the middle of moving；When screw drive block is moved to the optoelectronic switch of opposite side by screw rod, screw drive block drives
Sliding block is inwardly avoided in pedestal and moved, now the corresponding optoelectronic switch of screw drive block started by press.
Sliding block one end in the avoidance pedestal is in T shape, and top sets the chamber of sliding block and spring to be also in T words in pedestal
Shape, i.e., the side of described chamber is spring cavity, and opposite side is sliding block movable chamber, and spring retainer is stuck in the spring cavity of the chamber.
