Axial movement is generated between 404 and guide sleeve 405, so that guide sleeve 405 is travelled forward, guide sleeve 405 is with movable slider 4051, to realize push rod
The pushing action of 406 pairs of chamber doors 2 opens chamber door 2；
After chamber door 2 opens certain angle, when the fixed shifting block 4052 in 405 weeks sides of guide sleeve and limit switch 41 contact；
Control module controls motor 403 and inverts, while controlling longitudinal motor and intermittent gear 201 is driven to rotate, and makes intermittent gear 201 and hinge
Arc-shaped rack 301 on chain 3 engages, and is further opened chamber door 2 by the rotation of intermittent gear 201；
Motor 403 inverts, and makes guide sleeve 405 start to retreat by screw rod 404, when shifting block 4052 touches reset switch 42
When, control module controls motor 403 and stalls, and completes the homing action of telescopic device 4, retracts push rod 406 in telescopic device 4；
It is opened as preferably also the maximum of chamber door 2 can be controlled by the way that travel switch is arranged on arc-shaped rack 301
Position, or the rotation time of longitudinal motor is controlled to control the open position of chamber door 2 by the setting time relay；
After pressing door closing switch, longitudinal motor reversal passes through the arc-shaped rack 301 on intermittent gear 201 and hinge 3
Engagement, so that chamber door 2 be made to begin to shut off；Control module can the longitudinal motor stalling of delays time to control, guarantee intermittent gear 201 and hinge
Arc-shaped rack 301 on 3 completely disengages engagement；
As preferably can also be arranged on cabinet 1 travel switch further determine chamber door 2 closed state, guarantee chamber door
2 completely close.
When being not required to automatic opening and closing door, chamber door 2 can be directly pulled open manually, at this time the circle on intermittent gear 201 and hinge 3
Arc-shaped rack 301 is in the state for completely disengaging engagement；Opening the door additionally to cause between cog to wear, while also ensuring enabling
Smoothness.
Control module can also be equipped with current detection module, after the operation of chamber door 2 is restricted, motor 403 or longitudinal motor
It cannot continue to run, then generate locked rotor current, electric current increases, and reaches given threshold, then motor 403 or longitudinal motor stop turning
Dynamic, device generates failure when having prevented article from causing to stop to chamber door 2；It may also set up scram button, opened or closed in chamber door 2
When Shi Fasheng emergency case, convenient for stopping opening or closing for chamber door 2 in time.
