Description

Technical Field

[0001] This invention relates to the technical field of anti-theft safes, specifically a type of financial anti-theft safe. Background Technology

[0002] Based on different password working principles, safes can be divided into two types: mechanical safes and electronic safes. Early safes were mostly mechanical. Electronic safes incorporate electronic locks using intelligent control methods such as electronic passwords and IC cards. Their advantages include ease of use; currently, electronic safes are the most widely used and simple to operate. An electronic safe consists of a cabinet and a door. The cabinet contains storage slots for valuables, and the door is equipped with an electronic lock. The electronic lock controls the bolt's insertion or extension into a groove in the cabinet, allowing the safe to be opened and closed. However, in actual use, the storage slots in commercially available electronic safes have no other obstructions besides the door. If a thief directly breaks the door, they can easily take the valuables, resulting in poor security. Therefore, we provide a safe for valuables to address the shortcomings of existing technology.

The GPS positioning module is connected to the intranet and transmits and records signals using a dot matrix pattern.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes a self-locking mechanism, a contact sensor, and a PLC controller. The contact sensor determines whether the outer cabinet door has been forcibly pried open. When the user correctly enters the password for the electronic lock to open the outer cabinet door, the PLC controller receives the password and compares it. If the password is correct, the electronic lock is released. At this time, the PLC controller cuts off power to the contact sensor, preventing the sensor from disconnecting after the outer cabinet door is opened, thus preventing the inner cabinet from self-locking. However, when the outer cabinet door is forcibly opened, the contact sensor loses its contact signal and transmits it to the PLC controller. Upon receiving the signal, the PLC controller immediately starts the drive motor and rotates the threaded rod. This causes the threaded rod to move the internal threaded slider forward, inserting the insert rod into the slot on the lock tongue, thus achieving self-locking of the inner cabinet door and preventing it from being opened. This improves the anti-theft effect of the safe, preventing thieves from directly damaging the door to take valuables.

[0015] 2. This invention, through its installation mechanism, secures the inner cabinet by fixing its bottom to the connecting rod and link, preventing movement. Simultaneously, when the user correctly enters the password to open both the outer and inner cabinet doors, the PLC controller immediately activates the drive motor to rotate the adjusting screw, which in turn moves the internal threaded slider forward, pushing the inner cabinet out of the outer cabinet. This facilitates the user's retrieval of items from the inner cabinet, enhancing convenience and improving the practicality and ceremonial feel of the anti-theft safe.

A slot 207 is fixedly opened on the lock tongue 206. A self-locking mechanism 3 is provided at the rear end of the locking plate 204.

[0021] The installation mechanism 4 includes an installation plate 401 fixedly connected to the bottom of the inner side of the outer cabinet 1. Slide rails 402 are fixedly connected to both sides of the top of the installation plate 401. A movable collar 403 is sleeved on the outer side of the slide rails 402. A connecting rod 404 is fixedly connected to the top of the movable collar 403. An operation box 405 is fixedly connected to the center of the top of the installation plate 401. A drive motor 406 is fixedly connected to the front end of the operation box 405. A slot 412 is fixedly opened on the top of the operation box 405, and transverse sliding grooves 412 are fixedly opened on both sides of the interior of the operation box 405. 07. An adjusting screw 408 is provided inside the control box 405. An internally threaded slider 409 is sleeved on the outside of the adjusting screw 408.

A movable collar 403 is slidably connected to the outside of the slide rail 402, and the top of the movable collar 403 is fixedly connected to the bottom of the inner cabinet 2 through a connecting rod 404. The rear end of the adjusting screw 408 is rotatably connected to the rear end inside the control box 405 through a bearing. The front end of the 8th drive motor 406 is fixedly connected to the output end of the second drive motor 406, and the adjusting screw 408 is threadedly connected to the internal thread slider 409. The second drive motor 406 is electrically connected to the PLC controller 203. The internal thread slider 409 is slidably connected to the transverse sliding grooves 407 opened on both sides of the operation box 405 through the guide sliders 410 set on both sides. The connecting rod 411 passes through the slot 412 and is fixedly connected to the bottom of the inner cabinet 2, and the connecting rod 411 is slidably connected to the slot 412. By connecting the bottom of the inner cabinet 2 to the connecting rod 404 and the connecting rod 41, the connection is completed. The fixed connection prevents the inner cabinet 2 from moving and secures it. Simultaneously, when the user correctly enters the password to open both the outer cabinet door 102 and the inner cabinet door 201, the PLC controller 203 immediately starts the drive motor 406, which rotates the adjusting screw 408. This causes the adjusting screw 408 to move the internal threaded slider 409 forward, pushing the inner cabinet 2 out of the outer cabinet 1. This facilitates the user's access to items inside the inner cabinet 2, providing convenience and enhancing the practicality and sense of ceremony of using the anti-theft safe.

[0022] The self-locking mechanism 3 includes a drive box 301 fixedly connected to the rear end of the locking plate 204. A motor cover 302 is fixedly connected to the center of the rear end of the drive box 301. A drive motor 303 is fixedly connected inside the motor cover 302. Limiting grooves 304 are fixedly provided on both the upper and lower sides inside the drive box 301. A threaded rod 305 is provided at the center inside the drive box 301. An internally threaded slider 306 is sleeved on the outside of the threaded rod 305. Push rods 307 are fixedly connected to both the upper and lower sides of the internally threaded slider 306. A limiting slider 3 is fixedly connected to the side of the push rod 307 away from the internally threaded slider 306. 08. A push rod 307 has a fixedly connected insert rod 309 at its front end. The front end of the threaded rod 305 is rotatably connected to the front end of the drive box 301 via a bearing. The rear end of the threaded rod 305 is fixedly connected to the output end of the drive motor 303. An internal threaded slider 306 is threadedly connected to the threaded rod 305. The push rod 307 is slidably connected to the limiting slide groove 304 via a limiting slider 308. The insert rod 309 passes through the drive box 301 and the locking plate 204 and is engaged and fixed in the slot 207 on the locking tongue 206. The insert rod 309 is slidably connected to the drive box 301 and the locking plate 204 at the point where they pass through. The drive motor... Electronic lock 103 is electrically connected to PLC controller 203. It uses contact sensor 106 to determine if the outer cabinet door 102 has been forcibly pried open. When the user correctly enters the password for electronic lock 103 to open the outer cabinet door 102, PLC controller 203 receives the password and compares it. If the password is correct, electronic lock 103 is unlocked. At this time, PLC controller 203 de-energizes contact sensor 106, preventing the signal from being triggered when contact sensor 106 disconnects after the outer cabinet door 102 is opened, thus preventing the inner cabinet 2 from self-locking. When cabinet door 102 is forcibly opened, contact sensor 106 loses its contact signal and transmits the signal to PLC controller 203. Upon receiving the signal, PLC controller 203 immediately controls drive motor 303 to start and rotate threaded rod 305. This causes threaded rod 305 to move internal threaded slider 306 forward, inserting insert rod 309 into slot 207 on latch 206. This achieves self-locking of inner cabinet door 201, preventing it from being opened and preventing thieves from directly damaging the cabinet door to take valuables, thus improving the anti-theft effect.

[0023] The outer cabinet door 102 is fixedly connected to the top front end of an electronic lock 103. A rotary lock 104 and a keyhole 105 are sequentially located at the front end of the outer cabinet door 102 and below the electronic lock 103. A base 101 is fixedly connected to the bottom of the outer cabinet 1. A battery is installed inside the base 101. The rear end of the outer cabinet door 102 is in contact with a contact sensor 106. Electronic lock 103, electronic lock 202, and contact sensor 106 are all electrically connected to a PLC controller 203. The PLC controller 203 has a data analysis module and a GPS positioning module. The GPS positioning module is connected to the intranet and transmits and records the location using a dot matrix signal. By setting a GPS positioning module on the PLC controller 203, the location can be transmitted and recorded using a dot matrix signal, making it easier for the owner to find the safe if it is lost.

[0024] The specific operation method of this invention is as follows: First, when using this financial security safe, the contact sensor 106 determines whether the outer cabinet door 102 has been forcibly pried open. When the user normally enters the password of the electronic lock 103 to open the outer cabinet door 102, the PLC controller 203 receives the password entered by the electronic lock 103 and compares it. If the password is correct, the electronic lock 103 is unlocked. At this time, the PLC controller 203 cuts off the power to the contact sensor 106, so that the signal of the contact sensor 106 disconnecting is not triggered after the outer cabinet door 102 is opened, thus preventing the inner cabinet 2 from locking itself. However, when the outer cabinet door 102 is forcibly opened, the contact sensor 106 loses the contact signal and transmits the signal to the PLC controller 203. After receiving the signal, the PLC controller 203 immediately controls the drive motor 303 to start and drive the threaded rod 305 to rotate. The threaded rod 305 drives the internal threaded slider 306 forward, inserting the insertion rod 309 into the slot 207 on the lock tongue 206. The inner cabinet door 201 is self-locking, preventing it from being opened. This ensures the safe is secure and prevents thieves from directly breaking the door to retrieve valuables, improving its anti-theft effect. Furthermore, by fixing the bottom of the inner cabinet 2 to the connecting rod 404 and connecting rod 411, movement of the inner cabinet 2 is prevented, thus securing it. When the user correctly enters the password to open both the outer cabinet door 102 and the inner cabinet door 201, the PLC controller 203 immediately starts the drive motor 406, which rotates the adjusting screw 408. This causes the adjusting screw 408 to move the internal threaded slider 409 forward, pushing the inner cabinet 2 out of the outer cabinet 1. This facilitates the user's access to the contents of the inner cabinet 2, enhancing its convenience and practicality. Moreover, by installing a GPS positioning module on the PLC controller 203, the location can be transmitted and recorded via a dot matrix signal, making it easier for the owner to locate the safe if it is lost.

[0025] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
