For ease of understanding, a safe in this embodiment is described in detail below in conjunction with the accompanying drawings:

Fig. 1 is the overall front view of the safe, and its viewing direction is viewed from front to back. As shown in FIG. 1 , a safe of the present invention includes a cabinet door 1 , a cabinet body 2 , a door pivot shaft 3 , and a handle 4 . The cabinet door 1 is connected with the cabinet body 2 through a door pivot shaft 3 .

Fig. 2 is a schematic diagram of the assembly of the safe door, and its viewing direction is from the back to the front, and the specific coordinate direction is shown in the coordinate system in Fig. 2 . Fig. 3 is a rear view after the safe door is assembled, and its specific coordinate direction is shown in the coordinate system in Fig. 3 . As shown in FIGS. 2 and 3 , the cabinet door 1 has a handle 4 , and the handle 4 has a transmission shaft 41 and a dial 42 . Connect the deadbolt mechanism 5 through the dial shaft 421 on the handle shifting block 42, and drive the deadbolt mechanism 5 to realize opening and closing the door.

Fig. 4 is a schematic diagram of the structure of the lock tongue mechanism, and its viewing direction is viewed from front to back, and the specific coordinate direction is shown in the coordinate system in Fig. 4 . The dead bolt mechanism 5 comprises a large dead bolt 51, a small dead bolt 52, and a connecting rod 53. The big deadbolt 51 has five first long waist holes 511, and the big dead bolt is inserted into the corresponding five first cylinders 21 on the cabinet door 1 through the five first long waist holes 511. Since the first cylinder 21 and the first cylinder Between the long waist holes 511 is clearance fit, so that the big dead bolt 51 cannot move up and down in the up and down direction. The first cylinder 21 has a threaded hole, and the screw 6 is locked with the washer 7 to limit the front and rear direction of the large lock tongue 51 . The big bolt 51 can only move left and right on the first cylinder 21, but cannot strung out the first cylinder 21 during the movement (see Figures 5 and 6). The big bolt 51 also has a second long waist hole 512 near the dial 42 of the handle 4 , the dial 42 has a dial shaft 421 , and the dial shaft 421 is inserted into the second long waist hole 512 of the big bolt 51 .

The small dead bolt 52 is fixed to the connecting rod 53 by two nuts 8 . The connecting rod 53 has a third long waist hole 532 in the vertical direction. The third long waist hole 532 is inserted into the second cylinder 22 on the cabinet door 1 and locked with the washer 7 by the screw 6 . The connecting rod 53 can move up and down on the second cylinder 22 through the third oblong hole 532 , and the second cylinder 22 will not be strung out during the movement.
