The purpose of the present invention is for user be easier to forget locker door and tradition machinery formula lockset lockhole it is exposed easily stolen Problem, a kind of automatic switch door lock provided and its automatic switch method.

（2）Technical solution

In order to solve deficiency in the prior art, the present invention provides such a automatic switch door lock and its automatic switch sides Method, the technical solution adopted by the present invention are：

A kind of automatic switch door lock, including pedestal, setting power plant on the base, locking system, switching device, institute Power plant is stated to include motor, the lead screw that is connected on the motor output shaft, the sliding block being connected on the lead screw, be connected to Stroke on the sliding block stops push jack, enabling travel switch, shutdown travel switch, and the enabling travel switch is equipped with first Tabletting, the shutdown travel switch are equipped with the second tabletting, and the stroke stops push jack and first tabletting, second pressure Piece movable contact, the locking system include fixed A axis pins and B axis pins, pin joint on the base on the A axis pins The unhook on the B axis pins of unhook torsion bar, pin joint, the unhook reduction torsion spring being connected on the B axis pins, the unhook reset First end hook connects on torsional spring are in the unhook front, and the unhook torsion bar includes head, bar tail, and the unhook includes hook Head, hook tail, the hook tail be flexibly connected with the head, and the switching device includes fixation C axis pins on the base, company Under door pull hook on the C axis pins of the enabling torsional spring on the C axis pins, pin joint, cabinet door, setting are connected on the inside of the cabinet door The lock in portion, be arranged the cabinet door inside upper part cabinet door reduction torsion spring, setting lock buckling groove on the base, be fixed on Shutdown sensing chip, the door-closing in-place of D axis pins, pin joint on the D axis pins on the pedestal indicates to switch, before the door pull hook Portion is equipped with left hook arm and right hook arm, groove is formed between the left hook arm and the right hook arm, after the door pull hook rear portion is equipped with Lever arm, the second end hook connects on the enabling torsional spring on the outside of the right hook arm, the shutdown sensing chip be equipped with upper piece and under Piece, the door-closing in-place instruction switch are equipped with third tabletting, and the upper piece downside is equipped with push rod.

Preferably, the push rod is set between the unhook and the third tabletting, and the push rod can not contact simultaneously To the unhook and the third tabletting, the sliding block be set to the bar tail and it is described after between lever arm, the gib head is towards institute It states right hook arm one end and is equipped with rounded corner.

Preferably, it is described break off relations be set to the unhook torsion bar below, it is described upper piece be set to the unhook above, the bottom sheet Below the unhook, the door pull hook is set to described break off relations in same level.

Preferably, after the cabinet door is opened, the lock buckling groove notch overlaps in the vertical direction with the groove notch, institute It states bottom sheet rear end and is located at the lock buckling groove rear upper, bar tail described in end in contact after the sliding block, the stroke stops push jack and connects Touch first tabletting front.

Preferably, after the cabinet door is closed, the left hook arm contacts on the inside of the lock, described in the gib head interior side contacts Right hook arm leading inside, bottom sheet rear end described in end in contact before the lock, the bottom sheet rear end is located on the lock buckling groove rear end Side, the push rod contact third tabletting front, lever arm rear end after the slip front contact is described, and the stroke stopping pushes away Piece contacts second tabletting front.

A kind of automatic switch method playing the role of automatic switch to cabinet door using above-mentioned automatic switch door lock, it is described automatic Method of switching includes the following steps：

1）Auto-unlocking：The motor drives the lead screw rotation, the lead screw that the sliding block is driven to slide backward, the sliding block Rear end pushes the bar tail, the unhook torsion bar to be rotated counterclockwise around the A axis pins, and the head pushes the hook tail, institute It states unhook to rotate clockwise around the B axis pins, the gib head is resetted far from the right hook arm, then the enabling torsional spring, institute Left hook arm is stated far from the lock, the right hook arm pushes the lock pop-up, while the stroke stops described in push jack contact First tabletting makes the motor automatic stop operate；

2）Automatically it shuts：The cabinet door is acted on by the cabinet door reduction torsion spring and being closed, and the lock falls on the lock buckling groove and institute In the notch for stating groove, the motor drives the lead screw rotation, the lead screw to drive the sliding block forward slip, the sliding block Front end push it is described after lever arm, the door pull hook is rotated clockwise around the C axis pins, while the unhook reduction torsion spring makes The spinning reduction counterclockwise that breaks off relations, the left hook arm push the lock to enter in the lock buckling groove, the right hook arm contact Gib head front end rounded corner pushes the unhook open, and the right hook arm front end is got into the gib head, and the gib head locks institute It states right hook arm, while the lock pushes the bottom sheet to rotate counterclockwise, makes upper piece rotation counterclockwise, the push rod contact The third tabletting, while the stroke stops push jack and contacts second tabletting, the motor automatic stop operating.

（3）Advantageous effect

The lead screw is driven to rotate by the way that the motor is arranged in a kind of automatic switch door lock of the present invention and its automatic switch method The sliding block is driven to slide back and forth, the sliding block rear end pushes the bar tail, the unhook torsion bar counterclockwise around the A axis pins Rotation, the head push the hook tail to rotate clockwise, and the unhook front end is equipped with the gib head, described in the gib head is detached from Right hook arm, because the door pull hook is connected with enabling torsional spring, the enabling torsional spring resets, and the left hook arm decontrols the lock, The right hook arm pushes the lock pop-up, realizes automatic door opening action, and by the way that the enabling travel switch is arranged, described The stroke on sliding block stops push jack and contacts first tabletting, motor automatic stop operating is realized, in the cabinet door by institute When stating the reset of cabinet door reduction torsion spring, by connecting the unhook reduction torsion spring in the unhook, described in motor drive Lead screw drive the front end of the sliding block push it is described after lever arm when, unhooks resets, the left hook arm promotion is described latch into Enter in the lock buckling groove, the gib head front end is equipped with rounded corner, and the right hook arm front end is got into the gib head, the gib head lock Right hook arm is stated in residence, and the lock pushes the bottom sheet to rotate counterclockwise, makes upper piece rotation counterclockwise, the push rod contact The third tabletting, while the stroke stops push jack and contacts second tabletting, the motor shuts down, and realizes automatic close Door lock stop is made, and by respective outer side edges as design, realizes the purpose of automatic switch locker door, has reached and avoided user Forget locker door and property be stolen lose and improve agency security can effect.
