Description

Technical Field

[0001] This application relates to the field of furniture connector technology, and in particular to a quick-release locking structure and method for a modular wardrobe. Background Technology

[0002] Modular wardrobes have become a mainstream home furnishing category due to their advantages of free combination, easy assembly, disassembly, and transportation. The connecting latches between modules directly determine assembly efficiency and cabinet stability. Currently, on-site assembly of modular wardrobes requires tools such as screwdrivers and nuts, making assembly time-consuming for a single person and resulting in poor splicing and positioning accuracy, thus limiting the installation efficiency, lifespan, and aesthetic appearance of modular wardrobes. The following problems currently exist:

[0003] 1. Existing modular wardrobes and latches generally use screws and screwdrivers for installation and disassembly, which results in low assembly efficiency. During assembly, each fastener must be aligned and tightened one by one, which does not meet the development needs of rapid assembly of modular furniture. The disassembly and assembly operations are cumbersome, and the core advantage of modular wardrobes being able to be flexibly reconfigured is lost.

[0004] 2. The existing latches lack a self-locking limit mechanism. After the panels are spliced, they simply rely on the latches to hold together, resulting in large gaps and loose fits. Over time, the cabinet is subjected to the weight of the clothes and vibrations from opening and closing the doors. Without a self-locking limit mechanism, the latches are prone to slipping and disengaging, causing the gaps between the panels to widen continuously. This leads to the entire cabinet swaying and tilting. Frequent loading and unloading of clothes brings continuous external force, which further exacerbates the loosening of the latches. Repeated re-locking and tightening is necessary, making maintenance cumbersome. Furthermore, excessive gaps between the panels affect the overall appearance and disrupt the neat visual effect of the wardrobe. In addition, when the cabinet is subjected to external forces such as ground shaking, pressure from heavy objects, vibrations from frequent opening and closing, and bumps during handling, the latches are prone to disengagement and the panels may loosen. Without an alarm, users will not be able to notice in time, and the cabinet is prone to tilting and collapsing, injuring people and damaging the stored items. Summary of the Invention

[0005] To overcome the shortcomings of the common screw-and-screw connection structure used for modular wardrobes and latches, which results in low assembly efficiency and requires meticulous alignment and tightening of fasteners during assembly—a situation that does not meet the rapid assembly needs of modular furniture—and to address the cumbersome disassembly and reassembly process that negates the core advantage of modular wardrobes' flexible reconfiguration, the latches lack self-locking and limiting mechanisms. Instead, the panels rely solely on simple snap-fit ​​mechanisms after splicing, leading to large gaps and loose fits. Over time, the cabinet bears the weight of clothing and the vibrations from opening and closing the doors. Without self-locking and limiting mechanisms, the snap-fits are prone to slippage and disengagement, causing the gaps between panels to widen and the entire cabinet to wobble and tilt. Frequent handling of clothing brings continuous external force, which further exacerbates the loosening of the latches, requiring repeated re-locking and tightening, making maintenance cumbersome. In addition, excessive gaps between cabinet panels can affect the overall appearance and ruin the neat visual effect of the wardrobe. Furthermore, when the cabinet is affected by external forces such as ground shaking, heavy object pressure, frequent opening and closing vibrations, and bumps during handling, the latches are prone to come loose on their own and the panels may loosen. Without an alarm, users cannot notice in time, and the cabinet is prone to tilting and collapsing, injuring people and damaging the stored items. The purpose of this invention is to provide a quick-installation latch structure and method for modular wardrobes to solve the above-mentioned shortcomings.

The positioning rod slides in the inner cavity of the positioning block, so that the positioning rod presses the first button.

[0015] A quick-assembly method for a modular wardrobe, using the quick-assembly locking structure of the aforementioned modular wardrobe, includes the following steps:

[0016] S1. Install the two quick-release components into the inner cavities of the first cabinet panel and the second cabinet panel respectively, so that the quick-release components are fixed in the inner cavities of the first cabinet panel and the second cabinet panel.

[0017] S2. The latching assembly is installed separately on two quick-release assemblies. When the first cabinet panel and the second cabinet panel need to be spliced ​​together, the separate latching assembly is inserted to allow the first cabinet panel and the second cabinet panel to be spliced ​​together. Under the action of the latching assembly, the first cabinet panel and the second cabinet panel are tightly connected.

[0018] S3. The first and second cabinet panels can be separated by the locking assembly, and the quick-release assembly can be quickly removed from the inner cavity of the first and second cabinet panels without the need for screws and screwdrivers to achieve quick assembly.

[0019] The technical solution provided in this application has at least the following technical effects or advantages:

[0020] 1. By adopting quick-release components, this invention effectively solves the problem of the low assembly efficiency caused by the common use of screws and screwdrivers for installation and disassembly in existing modular wardrobes and latches. Assembly requires each fastener to be aligned and tightened individually, which does not meet the development needs of rapid assembly of modular furniture. The cumbersome disassembly and assembly operations negate the core advantage of modular wardrobes' flexible reconfiguration. This invention, through quick-release components, eliminates the need for screws and screwdrivers, significantly improving cabinet assembly efficiency. It allows for rapid disassembly and assembly without the need for each fastener to be aligned and tightened individually, enabling precise positioning during assembly and ensuring a stable connection between the quick-release mechanism and the cabinet panel.

[0021] 2. By adopting a locking assembly, this design effectively solves the problem of existing locks lacking self-locking limiting mechanisms. These locks rely solely on simple snap-fits after panel splicing, resulting in large gaps and loose fits. Over time, the cabinet is subjected to the weight of clothing and vibrations from opening and closing the doors. Without self-locking limiting mechanisms, snaps are prone to slipping and disengaging, causing the gaps between panels to widen continuously. This leads to the entire cabinet swaying and tilting. Frequent loading and unloading of clothing generates continuous external force, further exacerbating the loosening of snaps. Repeated re-locking and tightening is necessary, making maintenance cumbersome. Furthermore, excessively large gaps between panels affect the overall appearance, disrupting the wardrobe's neat visual effect. Additionally, the cabinet is susceptible to damage from ground vibrations, heavy object pressure, and frequent opening and closing vibrations. When subjected to external forces such as bumps and knocks during handling, the latches can easily come loose and the panels can loosen. Without an alarm, users cannot notice this immediately, and the cabinet is prone to tilting and collapsing, injuring people and damaging stored items. The latch assembly of this invention can precisely limit the splicing position of the panels, reduce the connection gap, and ensure that the cabinet panels fit tightly. At the same time, it prevents the latches from slipping and coming loose, avoids the gaps from widening, ensures the stability of the cabinet, and eliminates shaking and tilting problems. In addition, when the latches come loose due to external forces such as ground shaking, heavy object pressure, vibration, and bumps, the alarm mechanism can detect the connection failure in time, conduct early inspections, and effectively avoid the risks of cabinet collapse, personal injury, and property damage.

[0035] For modular wardrobes and latches that commonly use screws and screwdrivers for installation and disassembly, this invention uses quick-release components to eliminate the need for screws and screwdrivers, significantly improving cabinet assembly efficiency. For latches without self-locking limiting mechanisms, where panels are simply snapped together after splicing, resulting in large gaps and loose fits, this invention precisely limits the splicing position of panels, reducing gaps and ensuring a tight fit. It also prevents latches from slipping or disengaging, avoiding widening gaps, ensuring cabinet stability, and eliminating wobbling and tilting issues.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1:

[0037] Please see Figure 1 and Figure 2As shown, a quick-release locking structure for a modular wardrobe includes a first cabinet panel 1 and a second cabinet panel 2. Both the first cabinet panel 1 and the second cabinet panel 2 have connecting grooves in their inner cavities, with slots on both sides of the connecting grooves. The positions of the connecting grooves and slots can be customized according to actual needs. Each connecting groove of the first cabinet panel 1 and the second cabinet panel 2 is equipped with a quick-release component 3. A locking component 4 is provided on the outer surface of the quick-release component 3. When the first cabinet panel 1 and the second cabinet panel 2 need to be joined, the quick-release component 3 is installed in the connecting groove within the inner cavity of the first cabinet panel 1 and the second cabinet panel 2. The quick-release component 3 is then fixedly installed within the inner cavity of the first cabinet panel 1 and the second cabinet panel 2 by interlocking with the slots. At this point, the locking components 4, which are separate on the two quick-release components 3, are connected to achieve the locking of the first cabinet panel 1 and the second cabinet panel 2.

[0038] Please see Figure 3 and Figure 4 As shown, the quick-release assembly 3 includes a connecting ring 31. An adjusting disc 32 is rotatably connected to the inner cavity of the connecting ring 31. Two sliding grooves 33 are formed on the outer surface of the adjusting disc 32, and the two sliding grooves 33 are symmetrical about the center of the adjusting disc 32. An insert block 34 is slidably connected to the inner cavity of the connecting ring 31. A drive rod 35 is fixedly installed on the outer surface of the insert block 34. A slot 36 is formed on the outer surface of the insert block 34, and each insert block 34 has two slots 36. A positioning mechanism 37 is provided on the inner wall of the connecting ring 31. The positioning mechanism 37 engages with the slots 36. The drive rod 35 is slidably connected to the sliding grooves 33. The insert blocks 34 on the first cabinet plate 1 and the second cabinet plate 2 are respectively inserted into the slots of the first cabinet plate 1 and the second cabinet plate 2. There are two connecting rings 31; one connecting ring 31 is fixedly connected to the first locking plate 41, and the other connecting ring 31 is fixedly connected to the first locking plate 41. The two locking plates 44 are fixedly connected. When splicing the first cabinet panel 1 and the second cabinet panel 2, the driving rod 35 slides in the inner cavity of the slide groove 33 by rotating the adjusting plate 32 in the inner cavity of the connecting ring 31. At this time, the insert block 34 is stored in the inner cavity of the connecting ring 31. The separate connecting ring 31 is placed in the connecting groove of the first cabinet panel 1 and the second cabinet panel 2. Then, the adjusting plate 32 is rotated again to make the insert block 34 and the slot engage, so that the connecting ring 31 is fixed in the inner cavity of the first cabinet panel 1 and the second cabinet panel 2 respectively. Then, the separate locking assembly 4 is engaged and connected, so that the first cabinet panel 1 and the second cabinet panel 2 are connected. By rotating the adjusting plate 32, the quick-release assembly 3 can be disassembled as a whole, so that the first cabinet panel 1 and the second cabinet panel 2 can be separated, thereby realizing the quick assembly and disassembly of the wardrobe panels.

[0039] Please see Figure 4 and Figure 5As shown, the positioning mechanism 37 includes a positioning block 371. A positioning rod 372 is slidably connected to the inner cavity of the positioning block 371. A retaining ball 373 is movably connected to one end of the positioning rod 372. A first alarm 374 is fixedly installed on the outer surface of the positioning block 371. A slip ring 375 is fixedly installed on the outer surface of the positioning rod 372. A first spring 376 is sleeved on the outer surface of the positioning rod 372. A first button 377 is provided on the inner wall of the positioning block 371. The first spring 376 is located between the slip ring 375 and the inner wall of the positioning block 371. The first button 377 and the first alarm 374 are electrically connected, and the pressing of the first button 377 controls the operation of the positioning mechanism. The first alarm 374 sounds, the slip ring 375 and the positioning block 371 slide together, the retaining ball 373 engages with the retaining groove 36, and when the insert block 34 moves, the retaining ball 373 and the retaining groove 36 disengage. At this time, the retaining ball 373 contacts the outer surface of the insert block 34 and squeezes the retaining ball 373. The positioning rod 372 slides in the inner cavity of the positioning block 371, so that the positioning rod 372 presses the first button 377. When the adjusting plate 32 rotates for adjustment, the engagement of the positioning mechanism 37 and the retaining groove 36 is used to position the insert block 34, so that the insert block 34 can be stored and exposed in place during disassembly and assembly, thereby ensuring that the connecting ring 31 can be disassembled. The inner cavities of the first cabinet panel 1 and the second cabinet panel 2 are removed, and the connecting ring 31 can be stably installed in the inner cavities of the first cabinet panel 1 and the second cabinet panel 2. During the rotation of the adjusting disc 32, the insert block 34 slides in the inner cavity of the connecting ring 31. At this time, the ball 373 and one of the slots 36 disengage, causing the insert block 34 to press against the outer surface of the ball 373. At this time, the positioning rod 372 slides in the inner cavity of the positioning block 371. The sliding of the positioning rod 372 causes the slip ring 375 to slide in the inner cavity of the positioning block 371 and press against the first spring 376. At the same time, the movement of the positioning rod 372 presses against the first button 377, causing the first spring 376 to be pressed against the first button 376. An alarm 374 sounds an alarm. When the locking ball 373 engages with another locking slot 36, the positioning rod 372 disengages and contacts the first button 377, thus stopping the alarm 374. By controlling the positioning and engagement of the locking ball 373 and the two locking slots 36, the insertion block 34 is stably inserted into the inner cavity of the first cabinet panel 1 and the second cabinet panel 2. Therefore, when disassembling and assembling the quick-release component 3, no screws and screwdrivers are required, which greatly improves the cabinet assembly efficiency. During assembly, there is no need to tighten the fasteners one by one to achieve quick disassembly and assembly. Precise positioning can be performed during the assembly process, so that the quick-release mechanism is stably connected to the cabinet panel. Example 2:

[0040] Please see Figure 2 and Figure 6As shown, the latch assembly 4 includes a first locking plate 41, a connecting plate 42 fixedly installed in the inner cavity of the first locking plate 41, and a tight connection mechanism 43 provided at one end of the connecting plate 42. There are two tight connection mechanisms 43. The first locking plate 41 is located on the outer surface of the second cabinet panel 2, and a second locking plate 44 is provided on the outer surface of the first cabinet panel 1. A latching mechanism 45 is provided in the inner cavity of the second locking plate 44, and a limit mechanism 46 is provided on the outer surface of the second locking plate 44. An alarm mechanism 47 is provided on both sides of the second locking plate 44. When connecting the first cabinet panel 1 and the second cabinet panel 2, the first locking plate 41 and the second locking plate 44 are brought close together, so that the connecting plate 42 is inserted into the inner cavity of the tight connection mechanism 43. During this process, the tight connection mechanism 43 and the alarm mechanism 47 are squeezed together, which is used to lock the first cabinet panel 1 and the second cabinet panel 2. When the first cabinet panel 1 and the second cabinet panel 2 are connected, a buffer is provided to prevent excessive force from causing collisions between the first locking plate 41 and the second locking plate 44, as well as between the first cabinet panel 1 and the second cabinet panel 2. Finally, the tight connection mechanism 43 and the latching mechanism 45 engage to self-lock the tight connection mechanism 43. The limiting mechanism 46 is used to prevent the alarm mechanism 47 from sounding when the first locking plate 41 and the second locking plate 44 are manually separated. However, when the first locking plate 41 and the second locking plate 44 are unplanned to be inserted or removed, that is, when the latching mechanism 45 and the tight connection mechanism 43 fall off under the influence of external force, the tight connection mechanism 43 will squeeze the alarm mechanism 47 and sound an alarm, reminding the staff that the first cabinet panel 1 and the second cabinet panel 2 have separated and need to be maintained in time.

[0041] Please see Figure 6 and Figure 8 As shown, the tight connection mechanism 43 includes a storage rod 431, with a second spring 432 installed inside the storage rod 431. A spring rod 433 is slidably connected to the inner cavity of the storage rod 431, and a pressure wheel 434 is rotatably connected to the end of the spring rod 433 away from the storage rod 431. The second spring 432 is located between the storage rod 431 and the spring rod 433. The storage rod 431 is fixedly connected to the connecting plate 42. When connecting the first cabinet panel 1 and the second cabinet panel 2, the connecting plate 42 is inserted into the inner cavity of the second locking plate 44. At this time, both ends of the pressure wheel 434 will trigger an alarm. When mechanism 47 contacts, the elastic rod 433 slides in the inner cavity of the storage rod 431 and compresses the second spring 432, so that the tight connection mechanism 43 has a buffering effect when entering the inner cavity of the second locking plate 44, thereby preventing the first locking plate 41 and the second locking plate 44, as well as the sides of the first cabinet plate 1 and the second cabinet plate 2 from being damaged by a strong collision when the external force is inserted. At the same time, after the connection is completed, the alarm mechanism 47 compresses the pressure wheel 434, so that the first locking plate 41 and the second locking plate 44, as well as the first cabinet plate 1 and the second cabinet plate 2, are in tight contact without any connection gaps.

[0042] Please see Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the locking mechanism 45 includes a hand lever block 451, a connecting rod 452 fixedly mounted on the outer surface of the hand lever block 451, a protrusion 453 fixedly mounted on the outer surface of the connecting rod 452 with rounded ends, a limit ring 454 fixedly mounted on the outer surface of the connecting rod 452, a third spring 455 sleeved on the bottom end of the connecting rod 452, a connecting strip 456 fixedly mounted on the bottom end of the connecting rod 452, and first inclined blocks 457 fixedly mounted on both ends of the connecting strip 456.

The width is such that when the connecting plate 42 and the second locking plate 44 are engaged, the connecting plate 42 can be inserted between the first inclined blocks 457. The limiting mechanism 46 includes a limiting frame 461, the inner cavity of which is slidably connected to the second inclined block 462. A push rod 463 is fixedly installed on the outer surface of the second inclined block 462. Third inclined blocks 464 are provided at both ends of the limiting frame 461. A limiting rod 465 is fixedly installed at the bottom end of the third inclined block 464. A fourth spring 466 is sleeved on the outer surface of the limiting rod 465.

A second button 475 is provided on the inner wall of the second locking plate 44. Both ends of the second button 475 are chamfered. A second alarm 476 is fixedly installed on the inner wall of the second locking plate 44. The second button 475 and the second alarm 476 are electrically connected, and pressing the second button 475 controls the second alarm 476 to sound an alarm. The second alarm 476 and the first alarm 374 have different timbre and loudness settings to facilitate problem differentiation and maintenance. The connecting block 472 and the fixing rod 473 are slidably connected. The fifth spring 474 is located between the connecting block 472 and the inner wall of the second locking plate 44. One end of the connecting block 472 is rounded.When the connecting block 472 moves, the rounded corner of the connecting block 472 presses against the second button 475. A limiting groove 477 is formed on the outer surface of the buffer block 471. The limiting groove 477 and the limiting rod 465 fit together, and the diameter of the limiting groove 477 is larger than the diameter of the limiting rod 465. When the connecting plate 42 is inserted into the inner cavity of the second locking plate 44, there is a gap between the pressure roller 434 and the inner wall of the second locking plate 44, and the inclined surface of the pressure roller 434 and the buffer block 471 are in close contact. When the first locking plate 41 and the second locking plate 44 are connected, the receiving rod 431 will squeeze the inclined surface of the first inclined block 457, causing the connecting strip 456 to move upward and squeeze the third spring 455. At this time, the connecting rod 452 slides in the inner cavity of the second locking plate 44, allowing the receiving rod 431 to pass through. The connecting strip 456, under the elastic force of the third spring 455, returns to its original position, causing the first inclined block 457 to block the storage rod 431, thereby achieving self-locking of the connection between the first locking plate 41 and the second locking plate 44. Since some space is usually reserved during assembly of the buckle, otherwise the buckle might not be able to be installed properly, there is some play in the installed buckle, resulting in some looseness in the middle of the parts. Therefore, when the pressure roller 434 passes through the buffer block 471, the inclined surface of the buffer block 471 presses against the pressure roller 434. Under the elastic force of the second spring 432, the pressure roller 434 moves closer to the innermost side of the second locking plate 44, thus ensuring a seamless connection between the first locking plate 41 and the second locking plate 44, achieving self-locking of the first locking plate 41 and the second locking plate 44. The cabinet panel 1 and the second cabinet panel 2 are tightly connected. When it is necessary to separate the first cabinet panel 1 and the second cabinet panel 2, that is, to separate the first locking plate 41 and the second locking plate 44, the connecting rod 452 is slid in the inner cavity of the second locking plate 44 by pulling the lever block 451. The upward movement of the connecting rod 452 causes the protrusion 453 and the first inclined block 457 to move upward. The upward movement of the first inclined block 457 causes the first inclined block 457 to disengage from the limiting position of the storage rod 431. Thus, under the action of external force, the connecting plate 42 and the tight connection mechanism 43 can be pulled out from the inner cavity of the second locking plate 44. At the same time, the upward movement of the protrusion 453 squeezes the inclined surface of the second inclined block 462. At this time, the push rod 463 slides in the inner cavity of the limiting frame 461. The sliding of the push rod 463 will... The inclined surface of the third inclined block 464 exerts pressure, causing the limiting rod 465 to move downward within the cavity of the limiting frame 461 and exert pressure on the fourth spring 466. The downward movement of the limiting rod 465 causes it to engage with the limiting groove 477, thus keeping the buffer block 471 fixed. Therefore, when the storage rod 431 moves outward, the connecting block 472 will not exert pressure on the second button 475. Consequently, the second alarm 476 will not sound an alarm during planned disassembly. However, when the cabinet is affected by external forces such as ground shaking, heavy object pressure, frequent opening and closing vibrations, or bumps during handling, the first cabinet panel 1 and the second cabinet panel 2 may undergo unplanned disassembly. In this case, the storage rod 431 exerts pressure on the first inclined block 457, causing deformation or damage to the first inclined block 457.This causes the storage rod 431 to disengage at the first inclined block 457. The movement of the storage rod 431 causes the pressure roller 434 and the buffer block 471 to be squeezed. Due to the unplanned external force at this time, the elastic force of the third spring 455 keeps the limiting ring 454 in contact with the outer surface of the second locking plate 44, and the elastic force of the fourth spring 466 keeps the third inclined block 464 in close contact with the top arm of the limiting frame 461. Therefore, the bottom end of the limiting rod 465 will not be inserted into the limiting groove 477. Thus, when the pressure roller 434 moves, it will squeeze the buffer block 471, causing the buffer block 471 to slide on the fixed rod 473 and squeeze the fifth spring 474. Simultaneously, the movement of the buffer block 471 causes the connecting block 472 to press against the second button 475, triggering the second alarm 476 to sound an alarm. This alerts staff to prevent the tight connecting mechanism 43 from unplannedly detaching from the inner cavity of the second locking plate 44. This allows for precise control of the panel splicing position, reducing connection gaps and ensuring a tight fit between the cabinet panels. It also prevents the buckles from slipping or disengaging, avoiding gap widening and ensuring cabinet stability, eliminating shaking and tilting. Furthermore, when external forces such as ground shaking, heavy object pressure, vibration, or impact cause the buckles to detach on their own, the alarm mechanism can promptly detect connection faults, allowing for early repairs and effectively mitigating the risks of cabinet collapse, personal injury, and property damage.

[0043] In summary, when it is necessary to splice the first cabinet panel 1 and the second cabinet panel 2, the quick-release assembly 3 is installed in the connecting groove of the inner cavity of the first cabinet panel 1 and the second cabinet panel 2. The quick-release assembly 3 is fixedly installed in the inner cavity of the first cabinet panel 1 and the second cabinet panel 2 by interlocking with the slot. At this time, the locking assembly 4, which is separate from the two quick-release assemblies 3, is connected to achieve locking of the first cabinet panel 1 and the second cabinet panel 2. When splicing the first cabinet panel 1 and the second cabinet panel 2, the driving mechanism is activated by rotating the adjusting disc 32 within the inner cavity of the connecting ring 31. The rod 35 slides within the inner cavity of the slide groove 33. At this time, the insert block 34 is housed within the inner cavity of the connecting ring 31, allowing the insert block 34 to be housed within the inner cavity of the connecting ring 31. The separate connecting ring 31 is placed in the connecting slot of the first cabinet panel 1 and the second cabinet panel 2. Then, the adjusting disc 32 is rotated again to engage the insert block 34 with the slot, fixing the connecting ring 31 within the inner cavities of the first cabinet panel 1 and the second cabinet panel 2 respectively. The separate locking assembly 4 is then engaged, connecting the first cabinet panel 1 and the second cabinet panel 2. The quick-release mechanism can be adjusted by rotating the adjusting disc 32. Component 3 is disassembled as a whole, separating the first cabinet panel 1 and the second cabinet panel 2, thus enabling quick assembly and disassembly of the wardrobe panels. The first locking plate 41 and the second locking plate 44 are brought close together, allowing the connecting plate 42 to be inserted into the inner cavity of the tight connection mechanism 43. During this process, the tight connection mechanism 43 and the alarm mechanism 47 exert pressure, serving as a buffer when connecting the first cabinet panel 1 and the second cabinet panel 2, preventing excessive force from causing collisions between the first locking plate 41 and the second locking plate 44, as well as between the first cabinet panel 1 and the second cabinet panel 2. Finally, the tight connection mechanism 43 and the lock... The latching mechanism 45 engages with the tight connection mechanism 43 to self-lock. The limiting mechanism 46 is used to prevent the alarm mechanism 47 from sounding when the first locking plate 41 and the second locking plate 44 are manually separated. However, when the first locking plate 41 and the second locking plate 44 are unplanned to be inserted or removed, that is, when the latching mechanism 45 and the tight connection mechanism 43 fall off under the influence of external force, the tight connection mechanism 43 will squeeze the alarm mechanism 47 to sound an alarm, reminding the staff that the first cabinet plate 1 and the second cabinet plate 2 have separated and need to be maintained in time.
