Description

Technical Field

[0001] This application belongs to the field of lock technology, specifically relating to an external lock for a safe. Background Technology

[0002] With the development of society and the economy and the significant improvement of people's living standards, both organizations and individuals are owning an increasing number of valuable items. These valuable items, such as important documents, jewelry, and rare collectibles, not only have economic value for their owners but also embody profound emotional and historical significance. To properly preserve these valuable items, safes have become a widely used and important device.

[0003] Currently, most safes on the market are equipped with locks, and these locks generally have multiple security features. For example, they may combine mechanical anti-theft locks with electronic locks, or employ multi-source composite intelligent password locks. Taking some high-security intelligent composite password safes as an example, their electronic locks include multi-source composite intelligent password locks and corresponding terminals. They generate a smart, transforming user ID by combining specific and random code segments, and then use an encryption algorithm to obtain the unlocking password, thus ensuring the safety of the safe to a certain extent. However, for safes storing particularly valuable items, the security of the existing locks is still insufficient to meet the needs of users. For example, in some high-end jewelry stores, the jewelry stored is priceless, and its theft would cause incalculable losses; in financial institutions, important contracts and confidential documents require extremely high security. Even if the safe's locks have multiple security features, users still expect to have an additional set of external locks to add a layer of security on top of the existing safe's locks, further reducing the risk of valuable items being stolen or subjected to other security threats.

[0018] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0019] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. Unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.

[0020] Furthermore, in the description of the embodiments of this application, various components on the drawings have been enlarged or reduced for ease of understanding, but this is not intended to limit the scope of protection of this application.

[0021] This application provides an external lock for a safe (hereinafter referred to as: lock). Figures 1-2 These are overall structural diagrams of the lock in this application from different angles, such as... Figures 1-2As shown, the lock includes a connecting rod 1, a movable rod 2, a first clamping part 3, a second clamping part 4, a first mounting plate 5, a second mounting plate 6, and a lock. The axial ends of the connecting rod 1 are connected to the first clamping part 3 and the first mounting plate 5, respectively. One end of the movable rod 2 passes through the first mounting plate 5 and is connected to the second clamping part 4. The first clamping part 3 and the second clamping part 4 are arranged opposite to each other. The second mounting plate 6 is sleeved on the outer periphery of both the movable rod 2 and the connecting rod 1 and can move axially along the outer periphery of the movable rod 2 and the connecting rod 1. Both the first mounting plate 5 and the second mounting plate 6 are provided with mounting ears for mounting the lock. In actual use, the relative positions of the first clamping part 3, the first mounting plate 5, and the connecting rod 1 remain fixed. The second clamping part 4 can drive the movable rod 2 to move relative to the first clamping part 3. After the first clamping part 3 and the second clamping part 4 clamp the outside of the safe, the second mounting plate 6 is pushed towards the first mounting plate 5. Once the mounting ears of both are aligned, the mounting ears of the first mounting plate 5 and the second mounting plate 6 can be locked and fixed by the lock. Through this structural design, the lock can be stably installed on the safe, forming a double protection with the safe's main lock, effectively improving the safety level of the safe and providing more reliable protection for the valuables inside. In some specific embodiments of this application, the first clamping part 3 and the second clamping part 4 are L-shaped structures, and their inner right-angled surfaces can precisely fit with the corners of the safe. This L-shaped structure design allows the first clamping part 3 and the second clamping part 4 to not only stably clamp the side of the safe through their horizontal edges, but also effectively limit the end face of the safe through their vertical edges when clamping the outside of the safe, greatly enhancing the stability of the clamping and preventing the lock from loosening or shifting due to external forces during use. At the same time, the regular shape of the L-shaped structure also makes the connection between the first clamping part 3 and the second clamping part 4 and the connecting rod 1 and the movable rod 2 more convenient and the force is more even, further improving the structural stability and service life of the entire lock.

[0022] In some preferred embodiments of this application, anti-slip pads are attached to the inner contact surfaces of the first clamping part 3 and the second clamping part 4. These anti-slip pads are made of elastic materials with a high coefficient of friction, such as rubber or silicone, and their surfaces may be provided with fine textures or raised structures. When the first clamping part 3 and the second clamping part 4 clamp the outside of the safe, the anti-slip pads can make close contact with the surface of the safe, effectively preventing relative sliding between the lock and the safe by increasing friction, and further improving the stability of clamping. At the same time, the elastic material anti-slip pads can also play a buffering role during the clamping process, avoiding direct contact between the rigid surfaces of the first clamping part 3 and the second clamping part 4 and the safe, thus preventing scratches or damage and providing good protection for the surface of the safe.

[0023] Furthermore, the extension direction of the mounting ear is the opposite extension direction of the vertical side of the first clamping part 3, which can avoid spatial interference between the mounting ear and the first clamping part 3, and at the same time provide a more reasonable operating space for the installation of the lock, making the assembly of the lock and the mounting ear more convenient.

[0024] In some preferred embodiments of this application, the connecting rod 1 includes multiple rods arranged side by side, and the movable rod 2 is located between the multiple rods and arranged side by side with the rods, so that the movable rod 2 is subjected to more balanced force during movement, and at the same time enhances the deformation resistance of the overall structure.

[0025] In some preferred embodiments of this application, the lock further includes a third mounting plate 7, which is connected to the other end of the movable rod 2 relative to the second clamping part 4, and the connecting rod 1 passes through the third mounting plate 7. The third mounting plate 7 can effectively limit and support the ends of the movable rod 2 and the connecting rod 1 away from the first clamping part 3, preventing them from tilting under force, and further improving the stability of the overall structure of the lock.

[0026] In some preferred embodiments of this application, the lock further includes a fixing part 8, which is connected to the outer periphery of the movable rod 2 and abuts against the end of the first mounting plate 5 facing the second mounting plate 6. The fixing part 8 can effectively limit the movement range of the movable rod 2, preventing the movable rod 2 from detaching from the first mounting plate 5 due to excessive movement. At the same time, it can provide a stable force support point for the first mounting plate 5, ensuring the accuracy of the cooperation of each component of the lock.

[0027] In some specific embodiments of this application, the outer periphery of the movable rod 2 is provided with external threads, and the fixing part 8 is sleeved on the outer periphery of the movable rod 2 and threadedly connected to the movable rod 2. The fixing part 8 is located between the first mounting plate 5 and the second mounting plate 6, and the end of the fixing part 8 facing the second mounting plate 6 can abut against the first mounting plate 5. Through the threaded connection, the fixing part 8 can flexibly adjust its position on the movable rod 2, thereby precisely controlling the movement stroke of the movable rod 2. At the same time, by means of the abutment relationship with the first mounting plate 5, it provides reliable positioning support for the lock in the clamped state, enhancing structural stability.

[0028] In some specific embodiments of this application, the movable rod 2 is stably connected to the third mounting plate 7 by means of a threaded connection and a nut. This connection method not only ensures the connection strength between the movable rod 2 and the third mounting plate 7, but also facilitates flexible adjustment of their relative positions according to actual assembly requirements. At the same time, the locking effect of the nut can effectively prevent the movable rod 2 from loosening from the third mounting plate 7 during the force process, further ensuring the stability of the overall structure of the lock.

[0029] Furthermore, an extension plate 9 is provided on the second mounting plate 6. The extension plate 9 is located at the end of the second mounting plate 6 facing the first mounting plate 5. It can not only abut against the second mounting plate 6 to enhance the tightness of the structural connection, but also reserve sufficient space for the installation of the fixing part 8, so as to avoid installation interference between the fixing part 8 and the second mounting plate 6.

[0030] In some preferred embodiments of this application, the lock is equipped with a positioning module, a photography module, a vibration detection module, and a communication module. The positioning module can track the location of the lock in real time to prevent loss and can push the location to the user terminal in time in case of abnormality. The photography module can automatically take pictures of the scene when the lock is abnormally unlocked. The vibration detection module can detect abnormal vibrations such as external prying and trigger an alarm. The communication module can push various abnormal information to the user terminal in time, thereby comprehensively improving the intelligent security performance of the lock.

[0031] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
