When closing the door, the barb 61 will enter the matching groove 11 and hit the collision piece 211, and the limiting rod 21 is turned clockwise. At this time, the second pressure spring 31 on the lower end of the lock cylinder slider 32 is in a compressed state. When the circular protrusion 212 leaves the first rectangular groove 322, rebounding of the second pressure spring 31 will push the lock cylinder slider 32 to move upward. In the first aspect, the toothed rack 213 on the upper end of the lock cylinder slider 32 drives the large teeth 41 on the double-layer gear 4 to rotate clockwise, and the small teeth 42 coaxially arranged with the large teeth 41 also rotate clockwise to drive the driving rod 53 to swing counterclockwise, so the T-shaped hook head 251 is clamped against the barb 61 on the buckling plate 6; in the second aspect, when the lock cylinder slider 32 moves upward, as the multipoint hook installing hole 321 is fixedly connected with the connecting rod protrusion 711 on the connecting rods 71; the connecting rod 71 connected with the lock cylinder sliding block 32 can move upward, and the multipoint hook lock bolt 73 connected with the connecting rod 71 will also pop out; and in the third aspect, the circular protrusion 212 may slip off to the included angle of the second rectangular groove 324; therefore, the door locking action is completed.
It is to be further explained that the rotating shaft 51 is also provided with a square-shaft hole 12 for connection with a square shaft (not shown in figures) ; the square shaft is fixedly connected with the external door handle; the door can be opened by only turning the square shaft clockwise, and the T-shaped hook head 521 of the rotating shaft 51 is rotated clockwise so as to be separated from the barb 61; at the same time, the driving rod 53 drives the small teeth 42 to rotate counterclockwise and the large teeth 41 rotates counterclockwise at the same time; in the first aspect, the large teeth 41 drives the lock cylinder slider 32 to move downwards while compressing the second pressure spring 31 downwards while the circular protrusion 212 slides upwards against a triangular area between the first rectangular groove 322 and the second rectangular groove 324, and the circular protrusion 212 is gradually compressed during ascending relative to the lock cylinder slider 32 until reaching a bottom end surface of the first rectangular groove 322; the first pressure spring 22 rebounds to abut the circular protrusion 212 against the included angle of the first rectangular groove 322, and at the moment, the lock cylinder slider 32 is in a compressed state; and in the second aspect, when the lock cylinder slider 32 moves downwards, as the multipoint hook installing hole 321 is fixedly connected with the connecting rod protrusion 711 on the connecting rod 71, the connecting rod 71 connected with the lock cylinder slider 32 moves downwards too, and the multipoint hook lock bolt 73 connected with the connecting rod 71 is retracted; so the unlocking action is completed through the two actions.
