[0001] The present invention relates to the technical field of safe lock body structures, and in particular to a high-reliability safe locking assembly and a safe with outstanding application effects. [Background Technology]
[0002] A safe is a special container used to store important documents and valuables. It can be divided into mechanical safes and electronic safes based on their working principles. Mechanical safes use a mechanical compass to control the opening and closing of the door, while electronic safes use a combination lock to control the opening and closing of the door through a circuit board.
[0003] The main focus of existing mechanical or electronic safes is generally on the security of the box. Most innovations are centered around strengthening the strength of the structural components themselves to avoid or reduce the possibility of prying. However, there are fewer innovations in terms of the operating stability and user experience of internal functional components. For example, power-off protection for the internal motor, the amount of force required to unlock the box with a key, etc., also affect the user's actual usage experience to a certain extent.
[0004] For example, the invention patent with application number CN202323329276.8 and patent name "A door lock structure of a safe and a safe" specifically discloses a door lock structure of a safe and a safe. The door lock structure of the safe includes a lock body fixing plate, on which a first lock movable mechanism, a second lock movable mechanism and a first driving member are provided. An elastic reset member is provided between the first lock movable mechanism and the lock body fixing plate. The first lock movable mechanism and the second lock movable mechanism are transmission-connected. The first lock movable mechanism includes a first lock, and the second lock movable mechanism includes a second lock; the first driving member is used to drive the second lock movable mechanism to move so that the second lock moves to an unlocked position; when the second lock movable mechanism is driven by the first driving member, it can instantly transmit to the first lock movable mechanism, so that the first lock moves to an unlocked position, and causes the elastic reset member to undergo elastic deformation; the elastic reset member rebounds and can drive the first lock movable mechanism to move so that the first lock and the second lock are reset to a locked position.
[0005] The above-mentioned prior art documents have the aforementioned series of problems. Based on this, it is necessary to improve and enhance the specific structure of the lock body assembly inside the device. [Summary of the invention]

[0045] When the emergency lock body 1271 and the door bolt assembly are locked, the second transmission rod 1276 and the third transmission rod 1277 are in a horizontally connected state.
[0046] The present application simultaneously provides a drive motor 124 and a bolt assembly driven by the drive motor 124 to move horizontally left and right; the bolt assembly includes a bolt frame 121 and at least one bolt 122 arranged on the bolt frame 121, and also includes a mechanical lock assembly for providing an emergency unlocking function; the mechanical lock assembly includes an emergency lock body 1271, a transmission rod assembly movably connected to the emergency lock body 1271, and a motor mounting plate 1279 for installing the drive motor 124, the transmission rod assembly is connected to the motor mounting plate 1279 relative to the other end of the emergency lock body 1271, and when the emergency lock body 1271 is running, it transmits power to the motor mounting plate 1279, driving the motor mounting plate 1279 to move horizontally, and the transmission rod assembly includes an emergency lock body 1271, a transmission rod assembly movably connected to the emergency lock body 1271, and a motor mounting plate 1279 for installing the drive motor 124 71 rotatably connected to the first transmission rod 1275, the second transmission rod 1276 movably connected to the safe cabinet panel 13 and the third transmission rod 1277 movably connected to the motor mounting plate 1279; one end of the first transmission rod 1275 is movably connected to the second transmission rod 1276 and one end of the third transmission rod 1277 through the same central rotating shaft or is connected to an intermediate transmission rod 1275 and then movably connected to one end of the second transmission rod 1276 and one end of the third transmission rod 1276 through the same central rotating shaft.

[0048] The function of the torsion spring 1272: Since the transmission assembly is relatively heavy, the force required to twist the mechanical key to close it is relatively large. The torsion spring 1272 can play an auxiliary role, making the actual operation easier.
[0049] The second transmission rod 1276 or the fixed block 1278 is also provided with a positioning bead screw for auxiliary positioning; the positioning bead screw includes a gasket 12761 and a screw column 12762 passing through the gasket 12761; the end of the screw column 12762 is a spherical protrusion structure; it also includes a limiting hole 12781 opened on the second transmission rod 1276 or the fixed block 1278; the spherical protrusion structure at the end of the screw column 12762 is embedded in the limiting hole 12781, which plays an auxiliary reinforcing role in maintaining the horizontal state of the second transmission rod 1276 and the third transmission rod 1277.

[0055] The travel switch assembly 123 can cut off the power supply in time to prevent overload operation and protect the motor.
[0056] The specific operation process is:
[0057] Open the door: Press the switch to power on, the motor rotates, driving the door bolt assembly to the left, hitting the first switch unit 1231, power off, the motor stops working, and the door opens;
[0058] Closing the door: The induction switch 129 is turned on, the motor rotates, and drives the door bolt assembly to move to the right, hitting the second switch unit 1232, cutting off the power, the motor stops working, and the door closes.
[0059] The function of the travel switch is to cut off the power in time, prevent overload operation, and protect the motor.
