The positioning plate 6 can be better reset after sliding under the rebounding action of the elastic pulling member 41, and it is more convenient to use.

[0062] Preferably, the elastic pulling member 41 is a spring.

[0063] Referring to Figures 1-11 After the door plate 1 is closed on the opening of the box body 3, the knob 40 is rotated to drive the driving shaft 10 to rotate, the first eccentric column 12 is downward relative to the vertical segment 311 of the second driving hole 31, and at the same time the first eccentric column 12 drives the mounting frame 4 to slide outward, the limiting plate 5 slides outward together with the mounting frame 4, the second eccentric column 13 rotates downward in the first circular segment 172 of the first driving hole 17, at this time the position of the positioning plate 6 remains unchanged, the rotating bolt 8 does not rotate relative to the bolt block 7, and the rotating bolt 8 and the bolt block 7 extend into the avoiding hole 9 in turn.

[0064] When the first eccentric column 12 moves into the second circular segment 312, the bolt 8 and the block 7 are completely extended out of the avoiding port 9, the knob 40 is continuously rotated, the first eccentric column 12 rotates in the second circular segment 312, at this time, the mounting frame 4 keeps the whole position unchanged; when the second eccentric column 13 rotates into the horizontal segment 171, the second eccentric column 13 is downward relative to the horizontal segment 171 of the first driving hole 17, at the same time, the second eccentric column 13 drives the positioning plate 6 to slide left, at this time, the positioning plate 6 slides left, at the same time, the positioning plate 6 slides downward relative to the mounting frame 4 as a whole, then the limiting plate 5 slides downward together with the positioning plate 6, the driving side rod 16 rotates downward, so that the bolt 8 rotates relative to the block 7, when the side rod 16 abuts against the bottom end of the strip-shaped positioning hole 24, the profile shape of the block 7 and the bolt 8 is staggered with each other.

[0065] The utility model can combine and utilize the mechanical lock or the electronic lock to control the rotation of the driving shaft 10, so that the mechanical lock or the electronic lock connected with the driving shaft 10 keeps the state that the part of the bolt 8 exceeding the profile range of the block 7 clamps the part of the box body 3 or the part of the door frame 2 when being locked, and the security of the safe is greatly increased.

[0066] The mounting frame 4 is designed together with the mechanical lock or the electronic lock, when the side rod 16 abuts against the bottom end of the strip-shaped positioning hole 24, only after unlocking the above-mentioned mechanical lock or the electronic lock, the driving shaft 10 can be twisted to realize the unlocking of the transverse displacement of the mounting frame 4, and the safety of use is further increased.

[0067] The above-mentioned is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and the equivalent structural transformation made according to the utility model specification and the drawing contents, or direct / indirect application in other related technical fields under the utility model concept of the utility model are included in the patent protection range of the utility model.
