2. Door closing action:
as shown in fig. 3, when the door is closed, lock cylinder 105 moves downward in direction a, lock cylinder 105 moves downward against sealing plate 230, when step 231 of sealing plate 230 contacts crank 242 of locking body 240, locking body 240 is driven to rotate in direction B against torsion force of torsion spring 250, distance of torsion spring 250 decreases, when locking body 240 rotates to a certain angle, distance of torsion spring 250 compresses to minimum, after continuing to move, distance of torsion spring 250 begins to increase again, torsion force direction begins to turn over, and lock tongue 241 acts on lock cylinder 105 at this time, so that the door is closed.
3. Locking action:
As shown in fig. 3, in the door-closed state, the middle of the operation panel 300 is provided with a heart-shaped structure 301, the housing 220 is provided with a positioning needle 310, one end of the positioning needle 310 is connected with the housing 220, one end of the positioning needle 310 is connected with the heart-shaped structure 301 of the operation panel 300, and when the operation panel 300 is driven to be attracted by the electromagnet 330, the positioning needle 310 moves from the unlocking position to the locking position along the path of the heart-shaped knot 301. At this time, the boss 302 of the operation plate 300 is inserted in front of the slider 290. When lock head 105 is pulled upward, lock head 105 acts on lock tongue 241, forcing lock body 240 to rotate against torsion of torsion spring, crank 242 of lock body 240 acts on step 231 of seal plate 230, causing seal plate 230 to move upward, and as seal plate 230 and slide block 290 are connected together, slide block 290 is also driven to move upward. When the slider 290 moves upward and contacts the boss 302 of the operation panel 300, the slider 290 is prevented from moving upward, and the sealing plate 230 and the locking body 240 are prevented from continuing to move, so that the door cannot be opened and locked.
4. Unlocking:
As shown in fig. 4, in the locked state, when the operation plate 300 is driven to be attracted by the electromagnet 330, the positioning needle 310 moves from the locked position to the unlocked position along the path of the heart-shaped structure 301, and at this time, the boss 302 of the operation plate 300 moves out of the slider 290. The sliding block 290, together with the locking body 240 and the sealing plate 230, can move up and down freely, and the door cover can be opened at this time, so as to realize the unlocking function.
5. Door opening action:
As shown in fig. 5, when the lock head 105 is pulled upwards, the lock head 105 acts on the lock tongue 241 to force the locking body 240 to rotate against the torsion force of the torsion spring 250, the crank 242 of the locking body 240 acts on the step 231 of the sealing plate 230 to move upwards, the distance between the torsion spring 250 decreases after the locking body 240 rotates, the distance between the torsion spring 250 compresses to the minimum after the locking body 240 rotates to a certain angle, the distance between the torsion spring 250 begins to increase again after the locking body 240 continues to move, the torsion force begins to turn over, and the door is opened under the action of the door opening force and the torsion force of the torsion spring 250; at this time, the sealing plate 230 seals the locking hole 106 again under the action of the spring 350.
The above embodiments are illustrative of the present invention, and not limiting, and any simple modifications of the present invention fall within the scope of the present invention.
