Description

Technical Field

[0001] This utility model relates to the field of safe manufacturing technology, specifically a three-sided locking system for an electromechanical integrated safe. Background Technology

[0002] Safes are generally used to store valuables such as cash, gold, and jewelry. Traditional safes mostly use mechanical locks, but with the development of electronic locks (fingerprint locks, combination locks, etc.), some safes on the market now use electronic locks for unlocking.

[0003] These safes with electronic locks are mainly divided into two categories. One type combines electromagnetic locks and mechanical locks. The electromagnetic lock restricts the movement of the locking rod assembly, and the electromagnetic lock is unlocked by fingerprint or password, thereby eliminating the restriction on the movement of the locking rod assembly. The handle then drives the locking rod assembly to achieve the purpose of unlocking. In essence, the other type also uses a mechanical lock to lock the safe. Another type uses an electronic lock to control a motor, which in turn drives the movement of a locking rod assembly to unlock the safe. For example, patent application CN201920717333.4, entitled "A Fingerprint Unlocking Safe," discloses a safe structure including a door and a cabinet body rotatably connected to one side of the door. Behind the door are a battery compartment, a control circuit board, a locking rod mounting plate, a locking rod, and a motor. The battery compartment is electrically connected to the control circuit board. The locking rod mounting plate is movably positioned on the other side of the door-cabinet connection. The locking rod is horizontally mounted on the mounting plate. The motor is electrically connected to the control circuit board and movably connected to the mounting plate via its output end. A fingerprint reader electrically connected to the control circuit board is located on the upper surface of the cabinet body. However, this design only has a locking rod on the side of the door, resulting in poor anti-theft performance; therefore, its structure needs further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a three-sided locking system for an electromechanical integrated safe that is structurally reasonable, has strong anti-theft capabilities, and is stable in operation.

[0005] The technical solution of this utility model is implemented as follows: A three-sided locking system for an electromechanical integrated safe includes a motor signal-connected to an unlocking device. A screw is connected to the motor and is drively connected to a main locking rod mounting plate. A main locking rod is mounted on the main locking rod mounting plate, which is horizontally movable and mounted on the safe door. The main locking rod mounting plate is linked with upper and lower auxiliary locking rod mounting plates, each with an auxiliary locking rod, and is vertically movable and mounted on the safe door. The unlocking device controls the motor to start, and the motor drives the linked main locking rod mounting plate and the upper and lower auxiliary locking rod mounting plates to move synchronously.

[0006] Further optimization measures for this technical solution are as follows: As an improvement, the specific structure for the linkage between the main locking rod mounting plate and the upper and lower auxiliary locking rod mounting plates is as follows: a connecting plate and a linkage turntable are respectively provided between the main locking rod mounting plate and the auxiliary locking rod mounting plates. The linkage turntable is rotatably connected to the cabinet door. A first linkage rod and a second linkage rod are correspondingly provided on both sides of the linkage turntable. One end of the connecting plate is fixed to the main locking rod mounting plate, and the other end has a first linkage groove vertically formed to match the first linkage rod. The auxiliary locking rod mounting plate has a second linkage groove horizontally formed to match the second linkage rod. The main locking rod mounting plate drives the linkage turntable to rotate through the cooperation of the first linkage groove and the first linkage rod, and then drives the auxiliary locking rod mounting plate to move through the cooperation of the second linkage rod and the second linkage groove, thereby realizing the linkage between the main locking rod mounting plate and the upper and lower auxiliary locking rod mounting plates; the transmission is reliable, stable, and has low resistance.

[0007] As an improvement, a guide groove is provided horizontally on the main lock rod mounting plate, and a guide post is provided on the cabinet door, with the guide post placed in the corresponding guide groove.

[0008] As an improvement, a limit sensor is installed on the cabinet door, and a protrusion that cooperates with the limit sensor is provided on the main locking rod mounting plate. The cooperation between the limit sensor and the protrusion limits the travel of the main locking rod mounting plate.

[0009] As an improvement, both the main locking rod mounting plate and the connecting plate are equipped with outer covers. These covers protect the internal components and also block some dust, thus extending their service life.

[0010] As an improvement, the main locking rod mounting plate is provided with a screw seat, and the screw rod is screwed to the screw seat.

[0011] As an improvement, the unlocking device can be a fingerprint device or a password device.

[0012] As an improvement, the motor is a stepper motor.

[0013] The advantages of this utility model compared with the prior art are: This utility model discloses a three-sided locking system for an electromechanical integrated safe. It has a reasonable structure and uses a motor connected to the unlocking device as a power source. Through the design of the main locking rod mounting plate and the auxiliary locking rod mounting plates on the upper and lower sides, the motor synchronously drives the extension and retraction of the three locking rods to achieve three-sided locking of the safe, which greatly improves the anti-theft performance of the safe.

[0019] like Figures 1 to 7 As shown, a three-sided locking system for an electromechanical integrated safe includes a motor 1 connected to an unlocking device 9 via a signal. A screw 2 is connected to the motor 1, and the screw 2 is driven by a main locking rod mounting plate 3. A main locking rod 31 is mounted on the main locking rod mounting plate 3. The main locking rod mounting plate 3 is horizontally movable and mounted on the door 4. The main locking rod mounting plate 3 is linked with upper and lower auxiliary locking rod mounting plates 5. Auxiliary locking rods 51 are mounted on the auxiliary locking rod mounting plates 5, which are vertically movable and mounted on the door 4. The unlocking device controls the motor 1 to start, and the motor 1 drives the linked main locking rod mounting plate 3 and the upper and lower auxiliary locking rod mounting plates 5 to move synchronously.

[0020] The specific structure of the main locking rod mounting plate 3 and the auxiliary locking rod mounting plates 5 on the upper and lower sides is as follows: a connecting plate 6 and a linkage turntable 7 are respectively provided between the main locking rod mounting plate 3 and the auxiliary locking rod mounting plate 5. The linkage turntable 7 is rotatably connected to the cabinet door 4. A first linkage rod 71 and a second linkage rod 72 are respectively provided on both sides of the linkage turntable 7. One end of the connecting plate 6 is fixed to the main locking rod mounting plate 3, and the other end is vertically provided with a first linkage groove 6a that matches the first linkage rod 71. The auxiliary locking rod mounting plate 5 is horizontally provided with a second linkage groove 5a that matches the second linkage rod 72.

[0021] The main locking rod mounting plate 3 is provided with a guide groove 3a in the horizontal direction, and the cabinet door 4 is provided with a guide post 41, which is placed in the corresponding guide groove 3a. The cooperation between the guide groove 3a and the guide post 41 allows the main locking rod mounting plate 3 to move in a set horizontal direction.

[0022] A limit sensor 42 is provided on the cabinet door 4, and a protrusion 32 that cooperates with the limit sensor 42 is provided on the main locking rod mounting plate 3. In this embodiment, the limit sensor 42 is a limit switch; the limit sensor 42 is located on both sides of the protrusion 32 to limit the stroke of the main locking rod mounting plate 3. When the protrusion 32 contacts the limit sensor 42, the motor 1 stops rotating.

[0023] Both the main locking rod mounting plate 3 and the connecting plate 6 are equipped with outer covers 8. The outer covers 8 can protect the internal parts and also block some dust, which helps to extend their service life.

[0024] The main locking rod mounting plate 3 is provided with a screw seat 33, and the screw rod 2 is screwed to the screw seat 33.

[0025] In this embodiment, the unlocking device 9 is a fingerprint device, but it can also be a password device. As an extension, Internet of Things (IoT) technology can be used, employing a mobile app as the unlocking device 9.

[0026] The motor 1 mentioned is a stepper motor. Using a stepper motor results in more stable operation and more precise control.

[0027] The three-sided locking system of this utility model includes a main locking rod mounting plate 3 and auxiliary locking rod mounting plates 5 on the upper and lower sides. The main locking rod mounting plate 3 is provided with main locking rods 31 at intervals, and the auxiliary locking rod mounting plates 5 are provided with auxiliary locking rods 51 at intervals. The auxiliary locking rod mounting plates 5 on the upper and lower sides are symmetrically arranged.

[0028] Working Principle: This three-sided locking system uses a motor 1 fixed to the cabinet door 4 as its power source. The unlocking device 9 (fingerprint unlocking) sends a control signal to start the motor 1, which drives the screw 2 to rotate. Since the main locking rod mounting plate 3 is restricted to horizontal movement, when the screw 2 rotates, it acts on the screw seat 33, causing the main locking rod mounting plate 3 to move to the left, and the main locking rod 31 on the main locking rod mounting plate 3 retracts inward. Simultaneously, as the main locking rod mounting plate 3 moves, it drives the connecting plate 6 to move. The first linkage groove 6a on the connecting plate 6 acts on the first linkage rod 71, thereby driving the linkage turntable 7 to rotate. The second linkage rod 72 on the linkage turntable 7 rotates accordingly. The second linkage rod 72 acts on the second linkage groove 5a on the auxiliary locking rod mounting plate 5, thereby causing the upper auxiliary locking rod mounting plate 5 to move downward (and the lower auxiliary locking rod mounting plate 5 to move upward), causing the auxiliary locking rod 51 on the auxiliary locking rod mounting plate 5 to retract inward. This achieves synchronous retraction of the locking rods on all three sides, completing the unlocking process, and the cabinet door 4 can then be opened.

[0029] When locking the cabinet door, the action steps are the opposite of the unlocking action. That is, the motor 1 reverses and drives the main locking rod mounting plate 3 to move to the right. This, through the connecting plate 6 and the linkage turntable 7, drives the upper auxiliary locking rod mounting plate 5 to move upward (the lower auxiliary locking rod mounting plate 5 moves downward), thereby realizing the synchronous extension of the locking rods on all three sides and completing the locking.

[0030] The locking system of this invention features locking rods on three sides of the cabinet door 4, greatly improving the anti-theft capability of the safe. Furthermore, the motor 1 uses screw 2 for drive, providing a degree of self-locking and preventing forced unlocking in the event of a power outage.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
