[0040] It is easy to understand that according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the present application.

[0041] Embodiment one:

[0042] The mechanism frame 11 and the guide post 12 are fixed on the door plate 1, the dead door bolt 13 is fixed on the left side of the mechanism frame 11, and the holes (not shown) matched with the door bolt 7 are opened on the right side and the upper / lower end of the mechanism frame 11, which plays a positioning and guiding role, so that the door bolt 7 can be buckled with the lock catch groove of the fireproof safe.

[0043] The device door plate 1 is the door body of the fireproof safe, which is installed on the fireproof safe through the hinge.

[0044] The lock plate assembly 5 is composed of a lock plate 51, a horizontal slide plate guide post 52, a small lock plate 53, a heavy lock pin holder 54, a heavy lock pin 55, a compression spring 56, a positioning plate 57, a resilient cylindrical pin 58, and an electronic lock lock body 20. The horizontal slide plate guide post 52 and the small lock plate 53 are fixed on the lock plate 51, the heavy lock pin holder 54 is fixed on the small lock plate 53, and the electronic lock lock body 20 is installed on the small lock plate 53. The heavy lock pin holder 54 has two holes (not shown) at the upper and lower ends that match the heavy lock pin 55, and the heavy lock pin 55 can move vertically up and down in the holes. The heavy lock pin 55 and the positioning plate 57 have holes (not shown) that match the resilient cylindrical pin 58, wherein the hole of the heavy lock pin 55 is an interference fit with the resilient cylindrical pin 58, and the hole of the positioning plate 57 is a clearance fit with the resilient cylindrical pin 58. The positioning plate 57 is installed on the electronic lock lock body 20, the heavy lock pin 55 is inserted into the compression spring 56 inside the heavy lock pin holder 54, and the resilient cylindrical pin 58 is pressed into the heavy lock pin 55 through the positioning plate 57. The compression spring 56 is under pressure.

[0045] The heavy lock pin holder 54, the heavy lock pin 55, the compression spring 56, the resilient cylindrical pin 58, and the positioning plate 57 form a heavy lock device. When the positioning plate 57 is detached from the resilient cylindrical pin 58, the compressed compression spring 56 is released, forcing the heavy lock pin 55 to move downward.

[0046] The horizontal slide plate 6 has a first horizontal guide slot 61 that matches the horizontal slide plate guide post 52, a second guide slot 66 that matches the guide post 12, a first inclined slot 67 / second inclined slot 68 that matches the inclined slot guide post 81, and a vertical slot 62 that matches the push block pin 101. The fold edge 63 has a lock bolt opening 64 that matches the lock bolt 201 and a heavy lock pin opening 65 that matches the heavy lock pin 55. The horizontal slide plate 6 has a door bolt 7 installed on the right side.

[0047] The horizontal slide plate 6 is positioned and connected to the horizontal slide plate guide post 52 and the guide post 12, and can move horizontally left and right. When the horizontal slide plate 6 moves to the left end of the first horizontal guide slot 61 and the second guide slot 66, it is blocked by the horizontal slide plate guide post 52 and the guide post 12 respectively, which is the locked door position. When the horizontal slide plate 6 moves to the right end of the first horizontal guide slot 61 and the second guide slot 66, it is blocked by the horizontal slide plate guide post 52 and the guide post 12 respectively, which is the open door position. When the horizontal slide plate 6 is in the locked door position, the lock bolt 201 is in the lock bolt opening 64, and the lock bolt end 202 blocks the right end of the lock bolt opening 64, so the horizontal slide plate 6 cannot move to the left, i.e., to the open door position. When the electronic lock is attacked and damaged, the positioning plate 57 is detached from the resilient cylindrical pin 58, the compressed compression spring 56 is released, forcing the heavy lock pin 55 to move downward, and its lower end enters the heavy lock pin opening 65. The horizontal slide plate 6 cannot move to the left, i.e., to the open door position, and the heavy lock pin 55 locks the door locking mechanism, making it impossible to open the door plate 1.

[0050] When the horizontal sliding plate 6 is in the door locking position, the door bolt up and down fixed frame 8 on the upper side of the mechanism frame 11 is in the uppermost position, and the door bolt up and down fixed frame 8 on the lower side of the mechanism frame 11 is in the lowermost position, when the horizontal sliding plate 6 moves to the left, i.e. the door opening position, the first inclined groove 67 / second inclined groove 68 acts on the inclined groove guide column 81, drives the door bolt up and down fixed frame 8 on the upper side of the mechanism frame 11 to move downward and the door bolt up and down fixed frame 8 on the lower side of the mechanism frame 11 to move upward, until reaching the door opening position.

[0051] The knob pin 101 is fixed on the knob 10.

[0052] One end of the handle shaft 9 is fixedly connected on the handle 4, the other end is fixedly connected in the hole (not shown) matched with the door panel 1, and the knob 10 is installed, the knob pin 101 is placed in the vertical groove 62, when the handle 4 is rotated, i.e. the knob 10 is rotated, the knob pin 101 acts on the vertical groove 62 to drive the horizontal sliding plate 6 to move left / right, so that the horizontal sliding plate 6 can be in the door opening / locking position.

[0053] The locking tongue 201 of the electronic lock cannot be rotated outside the electronic lock body 20, and can be rotated into the electronic lock body 20 under pressure when the password is pressed or the control rod 203 is pressed to open the lock, and the electronic lock circuit board is set for a period of time, and the locking tongue 201 is automatically rotated out under the condition of no obstruction, and then cannot be rotated.

[0054] The mechanical override lock 3 is fixedly connected in the hole (not shown) matched with the door panel 1, and the override knob 21 is installed, and the override knob 21 is rotated when the mechanical override lock 3 is opened / closed.

[0055] Key points Figures 1-2 , close the door panel 1, rotate the handle 4, i.e. the knob 10 is rotated, drive the horizontal sliding plate 6 to move right, and the right movement of the horizontal sliding plate 6 drives the door bolt up and down fixed frame 8 on the upper side of the mechanism frame 11 to move up and the door bolt up and down fixed frame 8 on the lower side of the mechanism frame 11 to move down, the door bolts 7 on the right side and the upper / lower end of the mechanism frame 11 are stretched out to the door locking position, and the locking tongue 201 blocked by the folded edge 63 is released and automatically rotated out of the electronic lock body 20 into the locking tongue opening 64, the locking tongue end 202 blocks the right end of the locking tongue opening 64, so that the horizontal sliding plate 6 cannot be moved left, i.e. to the door opening position, at this time the handle 4 cannot be rotated, and the door panel locking mechanism is in the door locking state.
