[0022] A safe is a security device typically located in a vault, bank, or post office. Safes store items including, but not limited to, valuable gems, precious metals, currency, or important documents (such as wills or property deeds). Currently, safes are generally installed in fixed locations on the ground, making it inconvenient to relocate them according to changes in the room layout. Furthermore, users often need to squat down to retrieve items, which is inconvenient.

[0023] To address the aforementioned technical problems, this invention proposes a wall-mounted safe.

[0024] Please see Figures 1 to 10 In one embodiment of the present invention, the wall-mounted safe includes: Safe body 1; The movable plate 2 is located on the side of the safe body 1 facing the wall 3; the wall 3 is provided with a horizontally arranged guide rail 4, and the movable plate 2 is provided with a guide 5. The guide 5 is slidably connected to the guide rail 4 through a first limiting component 6. The movable plate 2 is provided with a vertically arranged slide groove 7, and the safe body 1 is provided with a slider 8. The slider 8 can be locked and slidably connected to the slide groove 7 through the height adjustment component 9. The slider 8 is provided with a plug groove 10, and the safe body 1 is provided with a plug block 11. The plug groove 10 and the plug block 11 are fitted together and connected, and the plug block 11 is fixedly connected to the plug groove 10 through the second limiting component 12.

[0025] The technical solution of this invention, on the one hand, combines a horizontally set guide rail 4 with a guide component 5 to form a horizontal adjustment component, and on the other hand, combines a vertically set slide groove 7 with a slider 8 to form a height adjustment component 9. This allows users to adjust the position of the safe body 1 according to their own height or usage scenario, moving and suspending it at a comfortable retrieval height, eliminating the need to squat down to retrieve or place items, and effectively improving user comfort. Furthermore, the dual limiting settings (first limiting component 6 and second limiting component 12) ensure that the safe body 1 remains stable when fixed or moved, preventing accidental sliding or tipping. Simultaneously, the safe body 1 and the slider 8 are connected by a "plug-in slot 10 + plug-in block 11" and fixed by the second limiting component 12, forming a quick-release structure. When it is necessary to replace the safe with one of different volumes later, there is no need to demolish the wall or re-drill holes; simply unlocking the second limiting component 12 allows the old safe to be separated and the new safe to be inserted, significantly reducing upgrade costs.

[0026] Specifically, at least two guide rails 4 are provided, and these two guide rails 4 are arranged parallel to each other. This arrangement distributes the weight of the safe body 1 to multiple guide rails 4 and corresponding wall anchoring points 3, forming at least two continuous load-bearing and anti-overturning moment paths. When the safe body 1 is subjected to longitudinal prying force or lateral impact, each guide rail 4 can work together to resist, significantly reducing the risk of single-rail twisting, bolt loosening, or local cracking of the wall 3. The parallel arrangement also ensures that the guide components 5 maintain the same horizontal reference during sliding, preventing the safe body 1 from getting stuck or tilted due to misalignment of the guide rails 4, thereby improving the stability and safety of the wall-mounted safe under static load and dynamic adjustment.

[0027] Specifically, the cross-section of the guide rail 4 is T-shaped; this design ensures that the guide component 5 can only move left and right along the rail direction and cannot disengage perpendicular to the rail direction. This geometry with a built-in "self-locking tongue" ensures that even if the safe body 1 encounters lateral thrust or accidental impact during horizontal adjustment, the guide component 5 will not be pried off the guide rail 4, thus ensuring that the connection between the movable plate 2 and the wall 3 is always reliable.

[0028] Specifically, expansion bolts 401 are installed at both ends of the guide rail 4, and the guide rail 4 is fixedly connected to the wall 3 through the expansion bolts 401. This arrangement means that each guide rail 4 is only anchored to the wall 3 at its two ends with a set of expansion bolts 401, while the middle section remains suspended without nails or glue. The advantage of this arrangement is that the stress points are concentrated at both ends, the bolt spacing is maximized, and hidden objects such as steel bars and wires inside the wall can be avoided, reducing drilling difficulty. At the same time, the anchoring at both ends forms a simply supported beam stress model, so that the bending moment generated by the weight of the safe body 1 is fully resisted at both ends, and the elastic deformation in the middle section is uniform, avoiding the over-constraint internal stress that may be caused by multiple fixation points. The expansion bolts 401 themselves have high pull-out and shear resistance, and can provide a safety margin of several times the self-weight of the safe body 1 even on concrete or solid brick walls, ensuring that the wall-mounted safe remains firm and does not loosen even after long-term use or when subjected to prying or impact.

[0029] Specifically, the cross-section of the slide 7 is T-shaped; this design ensures that the slider 8 can only move up and down along the slide and cannot come off perpendicular to the slide opening. This geometry with a built-in "self-locking tongue" ensures that even if the safe body 1 encounters lateral thrust or accidental impact during height adjustment, the slider 8 will not be pried off the slide 7, thus ensuring that the connection between the safe body 1 and the movable plate 2 is always reliable.

[0030] As a preferred embodiment of the above, the first limiting component 6 includes a first square groove 601 disposed on the movable plate 2 and the guide member 5, and a first square rod 602 is slidably connected inside the first square groove 601; the guide rail 4 has a plurality of first limiting grooves 402 opened along its track direction and on the side facing the movable plate 2, and the first end of the first square rod 602 can slide along the first square groove 601 to the inside of the first limiting groove 402; the first limiting component 6 also includes a first threaded rod 603, the second end of the first square rod 602 is provided with a first threaded groove 604, the first end of the first threaded rod 603 is threadedly connected to the first threaded groove 604, the middle part of the first threaded rod 603 is rotatably connected to the movable plate 2, the second end of the first threaded rod 603 extends to the outside of the movable plate 2, and a first rotating block 605 is fixedly provided at the second end of the first threaded rod 603. With this configuration, a first square groove 601 is first coaxially set on the movable plate 2 and the guide member 5, and a first square rod 602 that can only slide and cannot rotate is placed in the groove 601. The first threaded rod 603, which is coaxially arranged with the rod, is radially positioned in place by the movable plate 2 through the central shoulder and can only rotate. When the user turns the exposed first rotating block 605, the first threaded rod 603 converts the rotational motion into the linear motion of the first square rod 602, causing the first end of the first square rod 602 to extend and insert into any of the first limiting grooves 402 on the side of the guide rail 4, thus completing the instant positioning; the reverse rotation will disengage it from the first limiting groove 402, and the safe body 1 will return to the sliding state; thereby realizing the horizontal locking or unlocking of the safe body 1, avoiding accidental sliding during use, and effectively improving security.

[0031] As a preferred embodiment of the above, the height adjustment component 9 includes a vertically arranged second threaded rod 901, which is disposed in the slide groove 7. Both ends of the second threaded rod 901 are rotatably connected to the movable plate 2, and the middle portion of the second threaded rod 901 passes through the slider 8 and is threadedly connected to the slider 8. The movable plate 2 is provided with a first drive component 13, which is drively connected to one end of the second threaded rod 901. The first drive component 13 is used to drive the second threaded rod 901 to rotate. With this configuration, the height adjustment component 9 utilizes the screw drive principle. First, the upper and lower ends of the vertically arranged second threaded rod 901 are rotatably connected to the movable plate 2 through bearings or bushings. The middle portion of the rod is screwed into the internal threaded hole of the slider 8, forming a rotary-linear conversion pair. When the first drive component 13 drives the second threaded rod 901 to rotate, the slider 8 is circumferentially limited by the slide groove 7 of the T-shaped structure and cannot rotate with it, but can only move up and down along the rod axis, thereby smoothly raising and lowering the entire safe body 1. The threaded pair itself is both a transmission component and a load-bearing component. Its helix angle is less than the self-locking angle. After power is cut off or the operation is stopped, the cabinet will immediately maintain the set height without the need for additional pins or brakes. The entire mechanism is hidden in the slide groove 7, without taking up additional side space, making the overall appearance of the wall-mounted safe simple.

[0032] Specifically, the first drive assembly 13 includes a first motor 1301, with a first rotating rod 1302 fixedly mounted at the output end of the first motor 1301; a first bevel gear 1303 is fixedly mounted at the end of the first rotating rod 1302, and a second bevel gear 1304 is fixedly mounted at the end of the second threaded rod 901, with the second bevel gear 1304 meshing with the first bevel gear 1303. With this configuration, when the first motor 1301 is energized, the first rotating rod 1302 drives the first bevel gear 1303 to rotate, immediately driving the second bevel gear 1304 and the second threaded rod 901 to rotate synchronously, causing the slider 8 and the safe body 1 to rise and fall smoothly in the vertical direction, ensuring the smooth implementation of the technical solution of this application.

[0033] As a preferred embodiment, a connecting movable groove 701 is provided through the side of the slide groove 7, and the groove direction of the connecting movable groove is vertical; a connecting movable rod 801 is fixedly provided on the side of the slider 8, and the connecting movable rod 801 is slidably connected to the connecting movable groove 701. With this configuration, since the connecting movable rod 801 is exposed on the side of the movable plate 2, it serves as a visible "connecting bridge" between the safe body 1 and the slider 8, and also provides a bearing surface and assembly space for the subsequent installation of the second limiting component 12, etc.

[0034] As a preferred embodiment of the above, the second limiting component 12 includes a second square groove 1201 disposed in the connecting movable rod 801 and the slider 8, and a second square rod 1202 slidably connected inside the second square groove 1201; the side of the plug block 11 is provided with a second limiting groove 1101, and the first end of the second square rod 1202 can slide along the second square groove 1201 to the inside of the second limiting groove 1101; the second limiting component 12 also includes a third threaded rod 1203, the second end of the second square rod 1202 is provided with a second threaded groove 1204, the first end of the third threaded rod 1203 is threadedly connected to the second threaded groove 1204, the middle part of the third threaded rod 1203 is rotatably connected to the connecting movable rod 801, the second end of the third threaded rod 1203 extends to the outside of the connecting movable rod 801, and a second rotating block 1205 is fixedly disposed at the second end of the third threaded rod 1203. With this configuration, a second square groove 1201 is first coaxially arranged between the connecting movable rod 801 and the slider 8, and a second square rod 1202 that can only slide and cannot rotate is placed in the groove. The third threaded rod 1203, arranged coaxially with the rod, is radially positioned in place by the connecting movable rod 801 through the central shoulder and can only rotate. When the user turns the exposed second rotating block 1205, the third threaded rod 1203 converts the rotational motion into the linear motion of the second square rod 1202, causing the first end of the second square rod 1202 to extend and insert into the second limiting groove 1101, thus completing the insertion and locking. Reverse rotation will disengage it from the second limiting groove 1101, at which point the safe body 1 can be separated from the slider 8. This achieves the locking or unlocking of the safe body 1, ensuring a stable connection between the safe body 1 and the movable plate 2 and preventing loosening or detachment.

[0035] As a preferred embodiment of the above, the bottom of the safe body 1 is provided with an auxiliary displacement component 14. The auxiliary displacement component 14 includes a frame body 1401, and an I-shaped plate 1402 is slidably connected to the inside of the frame body 1401. A universal wheel 1403 is fixed at the corner of the I-shaped plate 1402. The auxiliary displacement component 14 also includes a lifting component 15, which is connected to the I-shaped plate 1402. The lifting component 15 is used to drive the I-shaped plate 1402 to move relative to the frame body 1401 to a first position and a second position. When the I-shaped plate 1402 moves to the first position, the universal wheel 1403 is stored inside the frame body 1401. When the I-shaped plate 1402 moves to the second position, the universal wheel 1403 extends out from the bottom end of the frame body 1401. With this configuration, the frame 1401 is fixed to the bottom of the safe body 1. Inside the frame 1401 is a sliding I-beam 1402, and each of its four corners is equipped with a caster wheel 1403. The lifting assembly 15 drives the I-beam 1402 to rise and fall, thereby causing the casters to switch between a first position and a second position. When the I-beam 1402 is in the first position, the casters wheel 1403 are fully retracted into the frame 1401, resulting in a clean and simple overall appearance for the wall-mounted safe. When movement is required, the lifting assembly 15 pushes the I-beam 1402 down to the second position, and the casters wheel 1403 extend from the bottom of the frame. At this point, the casters wheel 1403 can be used to easily push the safe to the target location, facilitating user movement of the safe body 1.

[0036] Specifically, the lifting assembly 15 includes a vertically arranged fourth threaded rod 1501, with both ends of the fourth threaded rod 1501 rotatably connected to the frame body 1401; the middle of the fourth threaded rod 1501 passes through the I-shaped plate 1402, and the fourth threaded rod 1501 is threadedly connected to the I-shaped plate 1402; the lifting assembly 15 also includes a second drive assembly 16, which drives the fourth threaded rod 1501 to rotate; with this configuration, the lifting assembly 15 utilizes the screw drive principle to achieve universal joint movement. The wheel 1403 switches between the first and second positions. Specifically, the vertically arranged fourth threaded rod 1501 is rotatably connected to the frame body 1401 at both ends via bearings, and the middle part of the rod body is screwed into the internal threaded hole of the I-beam plate 1402 to form a rotary-linear conversion pair. When the second drive assembly 16 drives the fourth threaded rod 1501 to rotate, the I-beam plate 1402 cannot rotate along with it because it is circumferentially limited by the frame body 1401, and can only move up and down along the rod axis, thereby driving the four corner casters 1403 to rise and fall synchronously. The thread helix angle is less than the self-locking angle, and the operation stops immediately upon power failure, thus ensuring the smooth implementation of the technical solution of this application.

[0037] More specifically, the frame body 1401 has limiting guide grooves 1404 on both sides of its interior, and the I-beam plate 1402 has limiting guide blocks 1405 fixed on both sides of its interior. The limiting guide blocks 1405 are slidably connected to the limiting guide grooves 1404. With this configuration, limiting guide grooves 1404 are respectively opened on the left and right inner sidewalls of the frame body 1401; correspondingly, the I-beam plate 1402 has protruding limiting guide blocks 1405 on both sides of its interior. The limiting guide blocks 1405 are embedded in the limiting guide grooves 1404 and can only slide along the groove direction. In this way, when the fourth threaded rod 1501 rotates, the I-plate 1402 is completely restricted in its rotational freedom due to the "block-groove" fit on both sides, retaining only vertical movement, thus converting the rotational motion of the threaded pair into 100% linear lifting and lowering; at the same time, the limiting guide groove 1404 bears the lateral force and overturning moment, preventing the I-plate 1402 from deflecting or getting stuck when the wheel set is in contact with the ground, ensuring that the caster wheel 1403 remains horizontal, synchronous, and stable throughout the extension and retraction process.

[0038] Specifically, the second drive assembly 16 includes a second motor 1601. A second rotating rod 1602 is fixed to the output end of the second motor 1601. The end of the second rotating rod 1602 is rotatably connected to the frame 1401. A first synchronous pulley 1603 is fixed to the middle of the second rotating rod 1602, and a second synchronous pulley 1604 is fixed to the middle of the fourth threaded rod 1501. The first synchronous pulley 1603 and the second synchronous pulley 1604 are connected by a synchronous belt 1605. With this configuration, the second drive assembly 16 uses the second motor 1601 as its power source. Its output shaft is fixed to the second rotating rod 1602, and the distal end of the second rotating rod 1602 is rotatably connected to the frame 1401 via a bearing, forming a vertically arranged rotating shaft. The first synchronous pulley 1603 is fixed to the middle of this shaft, while the second synchronous pulley 1604 is correspondingly fixed to the middle of the fourth threaded rod 1501. A toothed synchronous belt 1605 is fitted between the two pulleys. After the second motor 1601 starts, the second rotating rod 1602 drives the first synchronous pulley 1603 to rotate, and transmits the torque to the second synchronous pulley 1604 via the synchronous belt 1605, thereby driving the fourth threaded rod 1501 to rotate synchronously, so as to realize the smooth and reliable extension or retraction of the universal wheel 1403.
