Description

Technical Field

[0001] This utility model relates to the field of security lock technology, specifically to a remotely controllable office desk security lock. Background Technology

[0002] A desk lock is a security locking device specifically designed for office desks. It is mainly used to protect items inside the desk, such as documents, electronic devices, and personal belongings, and to prevent unauthorized opening or theft. Its core function is to physically restrict access to desk drawers, cabinet doors, or the desktop.

[0003] Currently, most office desk security locks still rely on traditional physical locks, i.e., keys. However, there are problems such as keys being easily lost, forgetting to bring the key, and lock cylinders rusting. At the same time, if the lock is frequently opened, it is inconvenient to carry, which can easily cause a lot of trouble in people's lives. Therefore, this utility model designs a remotely controllable office desk security lock to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is: a remotely controllable office desk security lock, including a drawer, with a buckle installed on the outer surface of the drawer and an unlocking mechanism installed on the inner surface of the drawer; the drawer is placed inside the office desk and can be slidably connected to the interior of the office desk, and the buckle facilitates the sliding of the drawer by external personnel.

[0005] The unlocking mechanism includes an unlocking plate, a safety component slidably connected to the outer surface of the unlocking plate, a wireless control motor fixedly connected to the side of the safety component away from the unlocking plate, and an unlocking box fixedly connected to the outer surface of the wireless control motor. Disassembly components are provided on both sides of the unlocking box. External personnel drive the safety component through the unlocking plate, thus facilitating the removal of the drawer from the inner wall of the desk.

[0006] Furthermore, a lifting rod is movably connected to the outer surface of the protective component, and a fixed shell is slidably connected to the outer surface of the lifting rod. A spring band is installed on the top of the inner surface of the fixed shell, and a limit plate is fixedly connected to the bottom end of the spring band. The entire unlocking mechanism uses the lifting rod to lock and unlock the drawer. When the lifting rod rises, it slides against the inner wall of the desk, thus hindering the drawer from being pulled out. When the lifting rod descends, the upper surface of the drawer is flush with the inner surface of the desk, allowing the drawer to be easily pulled out from inside the desk. The spring band functions similarly to a spring, possessing elasticity and a restoring function. As the lifting rod slides along the inner surface of the fixed shell, the limit plate restricts the sliding direction of the lifting rod, preventing the lifting rod from rotating during the sliding process.

[0007] Furthermore, the outer surface of the unlocking box is slidably connected to the inner surface of the drawer, the bottom of the fixed shell is installed on the upper surface of the unlocking box, the limiting plate is symmetrically installed on both sides of the lifting rod, and the side of the limiting plate away from the lifting rod is slidably connected to the inner surface of the fixed shell.

[0008] Furthermore, the protective component includes a rotating cylinder, with a pushing block fixedly connected to its outer surface. The inner wall of the rotating cylinder has an unlocking groove and a sliding semi-circular groove. A movable plate is slidably connected to the inner surface of the sliding semi-circular groove, and a rotating rod is installed at the bottom of the movable plate. When the unlocking plate is inserted into the unlocking groove, it can drive the rotating cylinder and the pushing block to rotate counterclockwise. The unlocking groove facilitates the entry of the unlocking plate. The movable plate is embedded inside the rotating cylinder, as shown in Figures 1 and 2. During counterclockwise rotation, it can rotate the cylinder and limit the position of the movable plate through the inner wall of the rotating cylinder.

[0009] Furthermore, the outer surface of the rotating cylinder is rotatably connected to the inner surface of the unlocking box, the inner surface of the unlocking groove is slidably connected to the outer surface of the unlocking plate, and the end of the rotating rod that is far from the lock groove is installed on the output shaft of the wireless control motor.

[0010] Furthermore, the disassembly component includes a placement groove, the inner wall of which is fitted with a fixed shaft. A pressing plate is rotatably connected to the outer surface of the fixed shaft. A rubber rod is fixedly connected to the side of the pressing plate near the rotating rod, and an oblique protrusion is provided on the side of the pressing plate away from the rubber rod. The rubber rod has elasticity and a restoring function. The pressing plate can enter the interior of the placement groove. In the initial state, the rubber rod has a pushing effect on the pressing plate.

[0011] Furthermore, the placement groove is formed on the inner surface of both sides of the unlocking box, and the end of the rubber rod away from the extrusion plate is installed on the inner surface of the unlocking box.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows for remote control of the wireless control motor inside the lock box via external devices. This motor drives the rotation of the rotating rod, movable plate, rotating cylinder, and pushing block. After rotating at a certain angle, it pushes the lifting rod upward, causing the top of the lifting rod to exceed the top height of the drawer and lock inside the desk, thus achieving the locking function without the need for an additional key. Similarly, when the lock is no longer needed, the wireless control motor can be used to drive the rotating rod to reverse, thereby unlocking the lock.

[0014] 2. In the event of remote control failure, this invention can also assist in unlocking via a safety component. Specifically, the operator inserts a specific unlocking plate into the unlocking slot, driving the unlocking plate and rotating cylinder to rotate counter-clockwise. This pushes the rotating block away from the bottom of the lifting rod, causing the lifting rod to reset under gravity, thus enabling assisted unlocking. Simultaneously, reversing the unlocking plate can also lock the device.

[0015] 3. This utility model also includes a disassembly component. The oblique protrusions on the surface of the pressing plate facilitate the worker's pushing of the pressing plate into the placement slot, i.e., the interior of the unlocking box. This further facilitates the worker's installation of the unlocking box into the drawer. After that, the pressing plate is released, and the bent end of the pressing plate will penetrate into the interior of the drawer to achieve a locking action. When the internal parts of the unlocking box are damaged and require repair, the pressing plate is pressed back into the interior of the unlocking box, and the unlocking box is pulled out along the interior of the drawer to complete the disassembly.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0027] Example 1:

[0028] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a remotely controllable office desk security lock, including a drawer 1, a buckle 2 installed on the outer surface of the drawer 1, and an unlocking mechanism 3 installed on the inner surface of the drawer 1; the drawer 1 is placed inside the office desk and can be slidably connected to the interior of the office desk, and the buckle 2 facilitates the sliding of the drawer 1 by external personnel;

[0029] The unlocking mechanism 3 includes an unlocking plate 31. A safety component 32 is slidably connected to the outer surface of the unlocking plate 31. A wireless control motor 33 is fixedly connected to the side of the safety component 32 away from the unlocking plate 31. An unlocking box 34 is fixedly connected to the outer surface of the wireless control motor 33. Disassembly components 35 are provided on both sides of the unlocking box 34. External personnel drive the safety component 32 through the unlocking plate 31, thereby facilitating the removal of the drawer 1 from the inner wall of the desk. The device remotely controls the wireless motor 33 by using an ESP8266 Wi-Fi module connected to an external router. A program is written to allow control devices such as mobile phones and computers to send control commands to the Wi-Fi module via the network. The Wi-Fi module then transmits these commands to the drive circuit of the wireless motor 33, enabling start and stop control. The wireless motor 33 used is a small brushed DC motor, model N20 micro motor, with a rated voltage of 3-6V and a rated current of 0.2-0.5A. It uses a DRV8833 dual H-bridge motor driver chip with built-in overheat protection and current limiting protection. Its advantages include simple structure, high reliability, low cost, and simple control method, making it suitable for applications with light loads. Combined with Wi-Fi control, it achieves a long control distance, allowing control from anywhere with Wi-Fi network coverage, making it suitable for environments such as offices. Finally, in this device, a 3.7V lithium battery is directly integrated inside the wireless control motor 33 for embedded installation, reducing the overall size, and is powered via a USB interface.

[0030] A lifting rod 36 is movably connected to the outer surface of the retaining component 32. A fixed shell 37 is slidably connected to the outer surface of the lifting rod 36. A spring band 38 is installed on the top of the inner surface of the fixed shell 37, and a limit plate 39 is fixedly connected to the bottom end of the spring band 38. The entire unlocking mechanism 3 uses the lifting rod 36 to lock and unlock the drawer 1. When the lifting rod 36 rises, it slides against the inner wall of the desk, thus hindering the drawer 1 from being pulled out. When the lifting rod 36 falls, the upper surface of the drawer 1 is flush with the inner surface of the desk, allowing the drawer 1 to be easily pulled out from the inside of the desk. The spring band 38 has the same function as a spring, having elasticity and a restoring function. During the sliding of the lifting rod 36 along the inner surface of the fixed shell 37, the limit plate 39 restricts the sliding direction of the lifting rod 36, preventing the lifting rod 36 from rotating during the sliding process.

[0031] The outer surface of the unlocking box 34 is slidably connected to the inner surface of the drawer 1. The bottom of the fixed shell 37 is installed on the upper surface of the unlocking box 34. The limiting plate 39 is symmetrically installed on both sides of the lifting rod 36. The side of the limiting plate 39 away from the lifting rod 36 is slidably connected to the inner surface of the fixed shell 37.

[0032] The protective component 32 includes a rotating cylinder 321. A push block 322 is fixedly connected to the outer surface of the rotating cylinder 321. An unlocking groove 323 and a sliding semi-circular groove 324 are formed on the inner wall of the rotating cylinder 321. A movable plate 325 is slidably connected to the inner surface of the sliding semi-circular groove 324. A rotating rod 326 is installed at the bottom of the movable plate 325. The unlocking plate 31 is inserted into the unlocking groove 323, which can drive the rotating cylinder 321 and the push block 322 to rotate counterclockwise. The opening of the unlocking groove 323 facilitates the entry of the unlocking plate 31. The movable plate 325 is embedded inside the rotating cylinder 321. Figure 5 and Figure 6 As shown, the rotation of the cylinder 321 can be achieved during the counterclockwise rotation, and the position of the movable plate 325 can be limited by the inner wall of the rotating cylinder 321.

[0033] The outer surface of the rotating cylinder 321 is rotatably connected to the inner surface of the unlocking box 34, the inner surface of the unlocking groove 323 is slidably connected to the outer surface of the unlocking plate 31, and the end of the rotating rod 326 that is far away from the lock groove 323 is installed on the output shaft of the wireless control motor 33.

[0034] In use, the wireless control motor 33 inside the unlocking box 34 is started by an external device. The wireless control motor 33 drives the rotation of the rotating rod 326 through the output shaft, which in turn drives the rotation of the movable plate 325. This causes the movable plate 325 to drive the rotation of the rotating cylinder 321, which in turn drives the rotation of the push block 322. During the counterclockwise rotation, the push block 322 can touch the lifting rod 36 above and drive the lifting rod 36 to slide upward along the inner surface of the fixed shell 37. During this process, the lifting rod 36 will also drive the movement of the limiting plate 39 and squeeze the spring band 38. When the lifting rod 36 moves upward a certain distance beyond the upper surface of the drawer 1, the drawer 1 is locked inside the desk, thus achieving the locking function.

[0035] When the locking is no longer needed, the rotating rod 326 and the movable plate 325 can be controlled clockwise again via the wireless control motor 33, where the movable plate 325 is made of magnetic material. Figure 6 As shown, magnetic material is also embedded inside the marked rotating cylinder 321. The magnetic material attracts the movable plate 325. Therefore, when the movable plate 325 rotates clockwise, it will also drive the rotating cylinder 321 to rotate clockwise, causing the push block 322 to disengage from the bottom of the lifting rod 36. The lifting rod 36 will then be reset under the action of gravity and the spring belt 38. In other words, the top of the lifting rod 36 will eventually descend below the surface of the drawer 1, without hindering the drawer 1 from being pulled out of the office desk.

[0036] When the intelligent control function fails, i.e., the wireless control motor 33 cannot be started via external devices, the lock can be manually unlocked using the safety component 32. Inserting the unlocking plate 31 into the unlocking slot 323 causes the lifting rod 36 to be pushed up by the upper surface of the push block 322, reaching the upper surface of drawer 1. At this point, drawer 1 is locked inside the desk. The unlocking plate 31 drives the rotating cylinder 321 to rotate counterclockwise, causing the push block 322 to disengage from the bottom of the lifting rod 36. The lifting rod 36 then resets under the influence of gravity and the spring band 38. During the rotation of the rotating cylinder 321, the sliding semi-circular groove 324 slides along the upper surface of the movable plate 325 until the inner wall of the groove on the other side of the sliding semi-circular groove 324 abuts against the side plate of the movable plate 325, preventing the rotating cylinder 321 from rotating further. When the magnetic material on the inner wall of the initial rotating cylinder 321 separates from the movable plate 325, the personnel need to overcome a certain magnetic force. The personnel's strength is greater than the magnetic attraction force, but at the same time, the attraction force of the two magnetic materials can make the movable plate 325 stick to the rotating cylinder 321.

[0037] When it is necessary to lock, the unlocking plate 31 and the unlocking groove 323 cooperate again to make the rotating cylinder 321 rotate counterclockwise until the inner wall of the rotating cylinder 321 is once again attached to the surface of the movable plate 325, so that the movable plate 325 and the rotating cylinder 321 are tightly attracted together by magnetic force.

[0038] Example 2:

[0039] Please see Figure 1 - Figure 9 This utility model provides a technical solution: Based on Embodiment 1, the disassembly component 35 includes a placement groove 351. A fixed shaft 352 is installed on the inner wall of the placement groove 351. A pressing plate 353 is rotatably connected to the outer surface of the fixed shaft 352. A rubber rod 354 is fixedly connected to the side of the pressing plate 353 near the rotating rod 326. An oblique protrusion 355 is provided on the side of the pressing plate 353 away from the rubber rod 354. The rubber rod 354 has elasticity and a restoring function. The pressing plate 353 can enter the interior of the placement groove 351. In the initial state, the rubber rod 354 has a pushing effect on the pressing plate 353.

[0040] The placement groove 351 is formed on the inner surface of both sides of the unlocking box 34, and the end of the rubber rod 354 away from the extrusion plate 353 is installed on the inner surface of the unlocking box 34.

[0041] In use, before inserting the unlocking box 34 along the inner wall of drawer 1, press the oblique protrusions 355 on the outer surface of the pressing plate 353 with both hands on both sides of the unlocking box 34. This causes the pressing plate 353 to rotate around the outer surface of the fixing shaft 352 towards the side close to the rubber rod 354, allowing it to penetrate into the placement groove 351. When the unlocking box 34 is fully inserted into the drawer 1 along the inner surface of the drawer 1, the pressing plate 353 can be released again. As a result, the pressing plate 353 will reset under the elasticity of the rubber rod 354, and the bent part at the other end of the pressing plate 353 will enter the inner groove of the drawer 1, thus fixing it in place. This can fix the entire unlocking mechanism 3. When the device is damaged and needs repair, the repair personnel only need to press the pressing plate 353 into the interior of the unlocking box 34 from both sides, causing the bent part of the pressing plate 353 to disengage from the inner groove of the drawer 1. Then, the unlocking box 34 can be pulled out along the inner wall of the drawer 1.

[0042] Working principle:

[0043] First, an external device can remotely control the wireless control motor 33 inside the lock box 34 to start, and drive the rotation of the rotating rod 326, the movable plate 325, the rotating cylinder 321, and the pushing block 322. After rotating at a certain angle, the lifting rod 36 is pushed to move upward, so that the top of the lifting rod 36 exceeds the top height of the drawer 1 and is locked inside the desk, thus achieving the locking function without the need for an additional key.

[0044] Similarly, when the lock is not needed, the unlocking function can be achieved by controlling the wireless control motor 33 to drive the rotating rod 326 to reverse.

[0045] When remote control fails, auxiliary unlocking can be performed using the safety component 32. This involves inserting a specific unlocking plate 31 into the unlocking slot 323, driving the unlocking plate 31 and rotating cylinder 321 to rotate counter-clockwise. This pushes the rotating block away from the bottom of the lifting rod 36, causing the lifting rod 36 to reset under gravity, thus enabling auxiliary unlocking. Simultaneously, reversing the unlocking plate 31 can also lock the device.

[0046] This device is also designed with a disassembly component 35. The oblique protrusions 355 on the surface of the pressing plate 353 make it easy for the operator to push the pressing plate 353 into the placement slot 351, i.e., the interior of the unlocking box 34. This further facilitates the operator to insert the unlocking box 34 into the interior of the drawer 1. After that, the pressing plate 353 is released, i.e., the bent end of the pressing plate 353 will penetrate into the interior of the drawer 1 to achieve engagement. When the internal parts of the unlocking box 34 are damaged and need repair, the pressing plate 353 is pressed into the interior of the unlocking box 34 again, and the unlocking box 34 is pulled out along the interior of the drawer 1 to complete the disassembly.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
