Description

Technical Field

[0001] This utility model relates to the field of home appliance storage cabinet technology, and in particular to a disinfection cabinet with a synchronous linkage child lock structure. Background Technology

[0002] In modern kitchen designs that prioritize space efficiency, built-in disinfection cabinets have become a mainstream choice. These cabinets typically feature a pull-out door design, with internal shelves that can be smoothly pulled out or pushed in using guide rails. To achieve this, the guide rails are fixedly installed within the inner liner of the cabinet and extend outwards, working in conjunction with the shelves (drawers).

[0003] To ensure safety, especially the "child lock" function to prevent children from opening the cabinet, disinfection cabinets typically have independent locking devices on the back of the cabinet, corresponding to the guide rails on both sides of each door. However, this traditional locking method has significant drawbacks: firstly, each door's locking device is an independent unit, lacking a linkage control mechanism between them; secondly, multi-door designs mean that the number of locking devices needs to be increased in pairs or even exponentially. This directly results in an exceptionally complex overall locking structure with numerous parts, significantly increasing manufacturing costs and assembly time, as well as the probability of malfunctions and the difficulty of maintenance.

[0004] To address the aforementioned issues, solutions have emerged in the market that achieve synchronized locking by modifying the guide rails, such as the "Disinfection Cabinet with Guide Rail Linkage Child Lock Structure" disclosed in Chinese Patent CN220747938U. This technology enables the guide rails on both sides of the cabinet door to move in tandem through a linkage mechanism, simplifying the control logic to some extent. However, this solution still essentially requires a locking actuator on each of the left and right sides of the inner liner, i.e., two locking points, resulting in a relatively large number of components. More importantly, it usually requires specific structural modifications to the guide rail module itself to achieve the linkage function, increasing the complexity of design and manufacturing. Therefore, the existing guide rail linkage locking structure still has significant room for optimization in terms of the number of components, overall structural simplicity, and versatility. There is an urgent need for a linkage locking solution with fewer components, a simpler structure, and no need for complex guide rail modifications. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a disinfection cabinet with a synchronously linked child lock structure.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a disinfection cabinet with a synchronous linkage child lock structure, including a frame-shaped cabinet body, one side of the cabinet body is open and a cabinet door is provided, and an inner liner is provided inside the cabinet body; a plurality of cabinet doors are provided, each cabinet door is connected to a loading component, and is slidably installed on the inner liner or the cabinet body through a guide rail module; a linkage child lock module is installed on the back of the inner liner;

[0007] The linked child lock module includes a linked lock base, a linked lock drive assembly, and a linked synchronization component; the linked synchronization component is provided with several locking hooks along the vertical direction, and the carrying component is provided with a locking groove; the linked lock base is located on the back of the inner liner; the linked lock drive assembly can move the linked synchronization component and cause the several locking hooks to lock the locking grooves of different carrying components respectively.

[0008] Optionally, the linkage lock seat is a vertically extending long guide rail structure, fixed inside the inner liner; the linkage lock drive assembly is installed on the back side of the linkage lock seat; a vertical slide rail is provided on the front side of the linkage lock seat; the linkage synchronizing element or lock hook can slide within the vertical slide rail.

[0009] Optionally, the linkage synchronization component is a vertically colored long strip plate; a connecting plate is provided at the bottom of the locking hook; the connecting plate is installed on the linkage synchronization component.

[0010] Optionally, the locking hook and the connecting plate are integrally formed sheet metal parts.

[0011] Optionally, the linkage synchronization component is divided into several segments along the vertical direction; the connecting plate is hung between two vertical linkage synchronization components, or below the lowest linkage synchronization component; when the linkage lock drive assembly moves one of the linkage synchronization components up and down, multiple linkage synchronization components and the connecting plate can slide synchronously in the vertical slide rail.

[0012] Optionally, the connecting plate is slidably disposed on the vertical slide rail.

[0013] Optionally, the connecting plate is provided with connecting lugs, which can be snapped into and slidably disposed on the vertical slide rail.

[0014] Optionally, the loading assembly is provided with a locking piece on the side near the inner liner, and the locking piece has the locking groove.

[0015] Optionally, the inner liner has a clearance groove through which the locking hook passes and can move.

[0016] Optionally, the linkage lock drive assembly includes a solenoid valve and a return spring; the valve stem of the solenoid valve can drive the linkage synchronization element to slide, and the return spring can reset the valve stem.

[0017] The beneficial effects of this utility model are as follows: Significantly simplified structure and reduced number of parts: This solution only requires a single linked child lock module on the back of the inner liner. This module, through a linkage synchronization component and multiple vertical locking hooks, can simultaneously act on the locking grooves of all cabinet door loading components. The number of parts is reduced exponentially, greatly simplifying the overall structure. No need for guide rail modification, strong versatility and reduced costs: The locking actuation point (locking hook and locking groove) acts directly on the loading component itself, rather than relying on specific structural modifications to the guide rail module to achieve linkage or locking. This reduces the design dependence on the guide rail structure, allowing the child lock structure to adapt to more standard or existing guide rail modules, improving versatility, and avoiding the additional costs and process complexity caused by guide rail modification. Simplified assembly and maintenance, improved production efficiency: The single modular design on the back makes the assembly process more centralized and convenient, significantly reducing assembly time and difficulty. At the same time, the sharp reduction in the number of parts also means fewer potential failure points, making later maintenance or replacement more convenient and efficient, reducing production and maintenance costs.

[0030] Example

[0031] Reference Figures 1 to 4 The present invention proposes a disinfection cabinet with a synchronous linkage child lock structure, comprising a frame-shaped cabinet body 10, one side of which is open and has a cabinet door 20, and an inner liner 30 is provided inside the cabinet body 10; a plurality of cabinet doors 20 are provided, each cabinet door 20 is connected to a loading component 40 and is slidably installed on the inner liner 30 or the cabinet body 10 via a guide rail module 50; a linkage child lock module 60 is installed on the back of the inner liner 30;

[0032] The child lock module 60 includes a lock base 61, a lock drive assembly 62, and a synchronization component 63. The synchronization component 63 has several locking hooks 64 arranged vertically, and the carrying component 40 has a locking groove 41. The lock base 61 is located on the back of the inner liner 30. The lock drive assembly 62 can move the synchronization component 63 and cause the several locking hooks 64 to lock the locking grooves 41 of different carrying components 40 respectively.

[0033] This invention significantly simplifies the structure and reduces the number of components: Only one child lock module 60 needs to be installed on the back of the inner liner 30. This module, through a linkage synchronization component 63 and multiple vertical locking hooks 64, can simultaneously act on the locking grooves 41 of all cabinet door 20 carrying components 40. The number of components is reduced exponentially, greatly simplifying the overall structure. It eliminates the need for guide rail modifications, offering strong versatility and reduced costs: The locking actuation points (locking hooks 64 and locking grooves 41) act directly on the carrying component 40 itself, rather than relying on specific structural modifications to the guide rail module 50 to achieve linkage or locking. This reduces the design dependence on the guide rail structure, allowing the child lock structure to adapt to more standard or existing guide rail modules 50, improving versatility, and avoiding the additional costs and process complexity caused by guide rail modifications. It simplifies assembly and maintenance, improving production efficiency: The single back-mounted modular design makes the assembly process more centralized and convenient, significantly reducing assembly time and difficulty. At the same time, the sharp reduction in the number of parts also means fewer potential points of failure, making later maintenance or replacement more convenient and efficient, and reducing production and maintenance costs.

[0034] In this embodiment, the linkage lock seat 61 is a vertically extending elongated guide rail structure, fixed inside the inner liner 30; the linkage lock drive assembly 62 is installed on the back side of the linkage lock seat 61; a vertical slide rail 611 is provided on the front side of the linkage lock seat 61; the linkage synchronization component 63 or the lock hook 64 can slide within the vertical slide rail 611. The elongated guide rail structure simultaneously performs the triple functions of locking seat fixation, motion guidance, and drive assembly installation, reducing independent guide parts. The vertical slide rail 611 constrains the path of the lock hook 64, preventing skewing and jamming, making the locking action smoother and more reliable. The drive assembly is hidden on the back side, without adding extra space in the thickness direction, adapting to the design of a thin inner liner 30.

[0035] In this embodiment, the linkage synchronization component 63 is a vertically colored strip plate; a connecting plate 641 is provided at the bottom of the locking hook 64; the connecting plate 641 is installed on the linkage synchronization component 63. The vertical plate serves as a universal carrier, and the spacing of the locking hooks 64 can be freely adjusted to easily match cabinet doors 20 of different heights, such as double-door or triple-door structures. The connecting plate 641 is connected to the vertical plate by hooking / bolting, eliminating the need for welding or precise positioning, significantly reducing assembly difficulty.

[0036] In this embodiment, the locking hook 64 and the connecting plate 641 are integrally formed sheet metal parts. The stamping process forms them in one piece, eliminating welding / assembly processes, and the hook dimensions are more consistent, resulting in more precise locking.

[0037] In this embodiment, the linkage synchronization component 63 is divided into several segments along the vertical direction; the connecting plate 641 is hung between two vertical linkage synchronization components 63, or below the lowest linkage synchronization component 63; when the linkage lock drive assembly 62 moves one of the linkage synchronization components 63 up and down, multiple linkage synchronization components 63 and the connecting plate 641 can slide synchronously within the vertical slide rail 611. The segmented design solves the problem of easy deformation of a single long vertical plate. The connecting plate 641 simultaneously hangs on adjacent segments to form a rigid linkage chain. Driving a single segment can drive the entire system. A micro gap is maintained between the segments to prevent the inner liner 30 from jamming due to thermal expansion.

[0038] In this embodiment, in order to accurately position the vertical movement of the hook, the connecting plate 641 is slidably disposed on the vertical slide rail 611.

[0039] Preferably, the connecting plate 641 is provided with a connecting lug 642, which can be snapped into and slidably mounted on the vertical slide rail 611. The lug directly snaps into the slide rail, similar to the installation of drawer slides, which is convenient for installation and reduces labor time; the lug makes a firm and stable contact with the slide rail surface.

[0040] In this embodiment, the locking hook 64 is arranged in an "L" shape, including a locking bar 643 and a hook 644, which can be hooked into the locking groove 41.

[0041] In this embodiment, a locking piece 42 is provided on the side of the carrying component 40 near the inner liner 30, and the locking piece 42 has a locking groove 41. For thicker carrying components 40 such as drawers, or in cases where the depth is insufficient, it is not convenient to directly open the locking groove 41. Therefore, the locking piece 42 is locked on the rear side of the original carrying component 40, and the locking groove 41 is opened on the locking piece 42, so as to facilitate matching different carrying components 40 for locking.

[0042] In this embodiment, the inner liner 30 has a clearance groove 31 through which the locking hook 64 passes and moves. The clearance groove 31 provides a contactless movement channel for the locking hook 64, eliminating abnormal noise from metal friction.

[0043] In this embodiment, the linkage lock drive assembly 62 includes a solenoid valve 621 and a return spring 622. The valve stem of the solenoid valve 621 can drive the linkage synchronization component 63 to slide, and the return spring 622 can reset the valve stem. The solenoid valve 621 is connected to the electrical control center and can control the movement of the valve stem, thereby pushing the linkage lock rail to move. The return spring 622 can reset the valve stem when the limit lock is released. The return spring 622 defaults to tightening the lock hook 64, and automatically locks the cabinet door 20 when the power is off, which meets the mandatory standards for child locks.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
