Abstract
The present invention relates to an automatic door lock device. According to the technical scheme, when a main control board gives a locking signal, an electromagnetic coil is electrified with forward direct current to push a permanent magnet to move so as to drive the adjusting frame to move, the adjusting guide rail moves to a low potential position, and the locking block moves downwards under the elastic action of a movable contact switch reed to limit the spring bolt and realize the limitation of the spring bolt and the limitation of a door hook of the spring bolt so as to realize locking; when the master control board gives an unlocking signal, the electromagnetic coil is electrified with reverse direct current, the magnetic pole of the electromagnet is reversed, and the adjusting frame is pushed to move in the reverse direction, so that unlocking is realized.
Description
Technical field
The present invention relates to a kind of automatic door lock device.
Background technology
At present, on market, existing washing machine is all carry out by master control borad the automatic washing machine that controls, and it needs to arrange suitable cover door lock in running, to ensure machine safe handling.On the one hand prevent in washing process, cover is opened and causes the water in washing machine and clothing to throw away from inner core, and preventing on the other hand runs up during dehydration throws away clothing and the danger that causes.The cover door lock mainly automatic door lock device of washing machine, it is primarily of formations such as electromagnet or bimetal leaf, slide block, bolts.But because the volume of electromagnet type door lock is comparatively large, action is more complicated, and reliability is not enough; And the enabling of double-metal sheet type door lock has retardance, can not realize quick closure or openness, and belong to power consumption type, namely double-metal sheet type door lock will continue power consumption in the course of the work, then automatically terminates locking after abnormal power-down.The complex structure of these two kinds of automatic door lock devices, the problem that destabilizing factor is more, also exists deficiency in safety and reliability.
Summary of the invention
The object of the present invention is to provide a kind of automatic door lock device, this door lock assembly structure is simple, reliability and security high.
For achieving the above object, present invention employs following technical scheme: comprise lock core parts and spring bolt parts, described spring bolt parts comprises the upper cover and lower cover that cooperatively interact, dead bolt is provided with between upper cover and lower cover, one end of dead bolt is provided with first hole of matching with gate stop, the other end of dead bolt is provided with second hole of matching with lock core parts, and this end is provided with the Lock cylinder cover matched with lock core parts, described lock core parts comprise the lock core upper cover and lock core lower cover that match, adjustment rack is provided with in the space formed between described lock core upper cover and lock core lower cover, described adjustment rack be arranged on lock core under the rail plate that covers form and be slidably matched, described adjustment rack entirety is U-shaped, comprise parallel first, second plate and connection first, 3rd plate of the second plate, described first, plate face is in opposite directions respectively equipped with opposite polarity permanent magnet to second plate, solenoid is provided with between two permanent magnets, the outer plate surface of the 3rd described plate is provided with adjustment guide rail, the side of adjustment guide rail is provided with clamping block, clamping block is provided with the mutually close one side of adjustment guide rail the fixed part being fastened on and adjusting in guide rail, described clamping block adjusts it highly drive it to move up and down to realize and the unblock of dead bolt or locking by adjusting guide rail, perpendicular with it first is also provided with in described lock core lower cover, second column, the first described column is provided with dynamic tactile switch spring, and this dynamic switch spring that touches outwards overhangs and is arranged on clamping block, the second described column is provided with dynamic tactile switch, the first described column is also provided with dynamic tactile switch plug receptacle.
Described solenoid, dynamic tactile switch, the dynamic switch plug receptacle that touches all are electrically connected with master control borad.
The installing hole being provided with and being connected with body is covered under described.
Described adjustment guide rail comprises the first rail and second rail of above-below direction setting, the second described rail comprises the first straight rail paralleling and be shorter in length than the first rail with the first rail, the end of the described first straight rail left below is extended with oblique rail, and the end horizontal of oblique rail is extended with the second straight rail that rail straight with first parallels.
Described dead bolt is arranged in lower cover, and by spring supporting.
As shown from the above technical solution, door lock assembly of the present invention is when master control borad is to locking signal, solenoid leads to forward dc electricity, promote permanent magnet motion thus drive adjustment rack motion, adjustment guide rail runs to low gesture position, and clamping block moves down under the elastic reaction of dynamic tactile switch spring, and dead bolt is spacing, realize the spacing gate stop of dead bolt, to realize locking; When master control borad is to unlocking signal, solenoid leads to reverse direct current, and electromagnet pole is reverse, promotion adjustment rack runs back, now clamping block upwards fortune under the effect of adjustment guide rail, cancels its position-limiting action to dead bolt, namely dead bolt is cancelled to the position-limiting action of gate stop, to realize unlocking.
