[0037] Working principle: when working, after the rotation plate 102 is released from the restriction, the two groups of first springs 19 will generate elastic force to the rotation plate 102, driving the lower end of the rotation plate 102 to pop up outward, and through the rotation connection of the limiting block 101 and the fixed rod 18, the upper end of the rotation plate 102 will slide along the fan-shaped protrusions of the slot rotating block 16, at this time, the upper end of the rotation plate 102 has enough space to rotate in the middle part of the shell 1, then manually rotate the rotation plate 102, drive the slot rotating block 16 to rotate through the fixed rod 18, drive the square slot block 15 to rotate through the rotation of the slot rotating block 16, when the square slot block 15 rotates, drive the closing plate 104 to rotate, when one end of the closing plate 104 rotates upward, it is in the open state, and then the door can be opened, when the rotation plate 102 rotates, it will drive the torsional spring 103 to rotate, so that the torsional spring 103 rotates and compresses, when the door is closed, the rotation plate 102 is released, the pressure on the torsional spring 103 is released, and then the rotation plate 102 returns to the initial state, at this time, the closing plate 104 slides to the horizontal direction and returns to the closed state, thereby achieving the effect of automatic closing, in the process of controlling the opening of the closing plate, a torsional spring is arranged, through the rotation and rebound action of the torsional spring, when it is needed to be closed, the rotation plate is released through the rebound action of the torsional spring, drives the rotating plate to return to the initial state, and then drives the closing plate to also return to the initial state, thereby achieving automatic closing, reducing the situation that the user forgets to close, thereby reducing the situation that the door is not locked and the articles are lost, improving the safety and convenience, when it is needed to open the door, the adjusting plate 23 is slid downward in the adjusting slot 21, which can drive the sliding block 28 to slide downward, at this time, the fourth spring 211 can be compressed, when the sliding block 28 slides downward, the trapezoidal block 29 drives the limiting plate 27 to rotate, so that it is separated from the card point slot 212, and the third spring 210 fixed at both ends of the limiting plate 27 adjusts the acting force when the limiting plate 27 separates from the card point slot 212, so that the limiting plate 27 is in a stable state when it is separated, after the separation, the rotation plate 102 is elastically connected through the upper end to make the lower end pop up outward, thereby providing conditions for the rotation of the rotation plate 102, then the downward pressure on the adjusting plate 23 is released, at this time, through the elastic force of the fourth spring 211, the sliding block 28 and the adjusting plate 23 are driven to slide upward to return to the initial state, when it is needed to be closed, the limiting plate 27 is pressed to be re-clamped in the card point slot 212, thereby limiting and fixing the rotation plate 102, then the limiting plate 102 is limited to keep the closed state, when the adjusting plate 23 slides, the recessed strip 24 can increase the friction force, improving the stability when the adjusting plate 23 slides, this step fixes the rotation plate 102 through a group of sliding limiting structures, improves the position fixing of the rotation plate 102, reduces the situation that the rotation plate 102 pops up when it is closed, thereby improving the safety, when it is needed to open the rotation plate 102,The locking plug is inserted into the inner wall of the fitting block 32, and the core barrel 31 is rotated to drive the fitting block 32 to rotate. When the fitting block 32 rotates, it drives the insertion slot block 33 to rotate, which can make the insertion slot block 33 disengage from the insertion slot 35, thereby releasing the limitation of the insertion slide plate 34. Then, by releasing the clamping slot effect of the rotating plate 102, the rotating plate 102 can be released and rotated. When closing again, the insertion slot block 33 is connected with the insertion slot 35, and the rotating plate 102 is limited and cannot be moved. This step fixes the rotating plate 102 by limiting the insertion slide plate 34 when closing, thereby improving the fixing effect of the rotating plate 102 when closing, reducing the accidental opening of the rotating plate 102, and improving the safety when closing. When working, when the insertion slot block 33 is disengaged from the insertion slot 35, the end of the insertion slot block 33 is inserted into the connecting slot 42 for fixation by sliding upward, which can drive the insertion slide plate 34 to slide upward, so that when the lower end of the rotating plate 102 is ejected, the insertion slide plate 34 will not contact the positioning plate 2, thereby hindering the opening of the rotating plate 102. When closing, manually slide the connecting slot 43 to disengage it from the connecting slot 42. At this time, the fifth spring 44 generates elastic force to drive the insertion slide plate 34 to slide downward, which is convenient for clamping and fixing the insertion slide plate 34, thereby fixing the rotating plate 102. This step provides flexibility for the rotating plate 102 when opening and closing by sliding and fixing the insertion slide plate 34, and controls the insertion slide plate 34 to further fix the rotating plate 102. When working, when the lower end of the rotating plate 102 is forced to open the door lock, the insertion slide plate 34 will move, thereby generating pressure to the stressed gasket 52. When the stressed gasket 52 is pressed, it will be transmitted to the pressure alarm 51. When the pressure alarm 51 receives the signal, it will alarm. When the insertion slot block 33 is disengaged from the insertion slot 35 by rotating the lock core, the alarm can be contacted. This step can alarm when the door lock is forced to open, which can remind and improve the safety. When working, the dust cover 62 is used to close the lock core port, which can reduce the phenomenon that external dust enters the lock core and causes the lock core to age. This step improves the service life of the lock core by protecting the lock core from dust. When working, the gasket 7 can increase the friction area between the gasket 7 and the outside. This step improves the friction area between the gasket 7 and the outside, and improves the stability of the closing plate 104 when closing.
