Description

Technical Field

[0001] This utility model belongs to the field of storage box technology, specifically relating to a panel lock structure for a storage box. Background Technology

[0002] In existing drawer locking mechanisms for storage boxes, the use of panel-integrated handle locks is quite common. This type of structure typically locks the drawer by engaging a latch with the box body via the handle. However, in multi-drawer stacking layouts, especially in vertically distributed drawer structures, there are significant design flaws:

[0003] 1. Appearance compatibility defects

[0004] When the upper and lower drawers use independent panel lock structures, the handle structure is forced to be designed differently because the movement direction of the lock tongue of each drawer needs to correspond to the locking part of the top and bottom surfaces of the cabinet respectively.

[0005] For example, the upper drawer needs to be equipped with an upward-pulling handle, while the lower drawer needs to be equipped with a downward-pressing operating part. This makes it impossible to unify the appearance elements such as the shape and tilt angle of the handles of adjacent drawer panels, thus destroying the overall symmetrical aesthetics.

[0006] 2. Incoherent operational logic

[0007] In traditional designs, upper and lower drawers often use opposite operating directions to achieve different locking tongue movements (the upper locking tongue needs to move upward to lock the top surface, and the lower locking tongue needs to move downward to lock the bottom surface).

[0008] For example, the upper drawer requires pulling the handle upwards to unlock, while the lower drawer requires pressing downwards. This reverse operation mode goes against ergonomic intuition and increases the user's memory burden. Utility Model Content

[0009] This utility model addresses the aforementioned problems in the existing technology by proposing a panel lock structure for a storage box that achieves a unified appearance and unidirectional control of the double drawer handles.

[0010] This utility model can be achieved through the following technical solutions:

[0011] A panel lock structure for a storage box includes:

[0012] The outer casing has an inner cavity, and the top and bottom surfaces of the inner cavity are respectively provided with a first locking part and a second locking part;

[0013] An upper drawer and a lower drawer are arranged vertically and can be pulled out into the inner cavity of the outer casing. The upper drawer and the lower drawer are respectively equipped with a first panel lock and a second panel lock. The first panel lock includes a first handle, a first transmission mechanism, and a first locking bolt. The second panel lock includes a second handle, a second transmission mechanism, and a second locking bolt.

[0014] The first handle and the second handle are disposed at the same tilt angle on the outer end face of the upper drawer and the lower drawer, and the unlocking force direction of the first handle and the second handle is consistent.

[0015] The first transmission mechanism is configured to convert the operation of the first handle into a vertically upward locking action of the first locking tongue, so that the first locking tongue and the first locking part form a vertical lock engagement;

[0016] The second transmission mechanism is configured to convert the operation of the second handle into a vertical downward locking action of the second latch, so that the second latch and the second locking part form a vertical lock.

[0017] As a further improvement of this utility model, the first locking part and the second locking part are respectively provided with a first socket and a second socket, wherein,

[0018] When the first latch and the second latch are inserted into the first socket and the second socket respectively, the upper drawer and the lower drawer are locked and constrained.

[0019] When the first latch and the second latch disengage from the first socket and the second socket respectively, the upper drawer and the lower drawer are unlocked.

[0020] As a further improvement of this utility model, the first handle and the second handle have the same structure, both of which include a connected pull rod and a handle bracket. A first rotating shaft is installed between the handle bracket and the upper drawer or the lower drawer, and the handle bracket is connected to the first transmission mechanism or the second transmission mechanism. The pull rod drives the handle bracket to rotate, thereby driving the first transmission mechanism or the second transmission mechanism to operate.

[0021] As a further improvement of this utility model, the handle bracket is provided with a lifting part that protrudes outward and extends to the inner side of the panel of the upper drawer and the lower drawer. The lifting part is separated from the first locking tongue and is inserted into the clearance groove opened by the second locking tongue.

[0022] As a further improvement of this utility model, the first transmission mechanism includes:

[0023] The first locking tongue pressure plate is disposed inside the front panel of the drawer, and the first locking tongue is disposed within the space enclosed by the first locking tongue pressure plate that can move up and down.

[0024] The first spring has its two ends connected to the first latch plate and the first latch, respectively, and the first spring always provides the first latch with elastic force toward the first locking part.

[0025] As a further improvement of this utility model, the first transmission mechanism further includes:

[0026] A guide wheel bracket, which is connected to the first locking tongue pressure plate;

[0027] A fixed pulley is mounted on the guide wheel frame via a second rotating shaft;

[0028] The linkage rope has one end connected to the first locking tongue and the other end connected to the lifting part, and the linkage rope is embedded in the fixed pulley.

[0029] As a further improvement of this utility model, the second transmission mechanism includes:

[0030] The second latch plate is located inside the panel of the lower drawer, and the second latch is movable up and down within the space formed by the second latch plate.

[0031] The second spring has its two ends connected to the second latch plate and the second latch respectively, and the second spring always provides the second latch with elastic force toward the second locking part.

[0032] As a further improvement of this utility model, when the second handle is activated, the lifting part raises the second locking tongue upward and disengages it from the second socket.

[0033] As a further improvement of this utility model, a gap is left between the adjacent surfaces of the upper drawer and the lower drawer to serve as clearance space.

[0034] As a further improvement of this utility model, the first locking tongue and the second locking tongue have the same structure, and both of them have an arc-shaped guide surface at their locking ends.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. Enhanced Appearance Consistency: By unifying the design of the tilt angle and operating direction of the upper and lower drawer handles, the overall appearance of the storage box is more harmonious and aesthetically pleasing, enhancing the product's visual consistency and industrial design sense.

[0037] 2. Simplified operation logic: All drawers are unlocked using the same operation method (such as uniformly pulling up or pressing down), which avoids user confusion and memory burden caused by different directional operations in traditional designs, and improves user experience;

[0038] 3. Improve assembly and maintenance efficiency: Modular design allows for standardized production of components such as handles and latches, simplifying the assembly process and reducing maintenance difficulty, which helps to reduce manufacturing and after-sales service costs.

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0045] like Figures 1-2 As shown, this utility model provides a panel lock structure for a storage box, comprising:

[0046] The outer casing has an inner cavity, and the top and bottom surfaces of the inner cavity are respectively provided with a first locking part 110 and a second locking part 120;

[0047] The upper drawer 200 and the lower drawer 300 are vertically distributed and pull-out arranged within the inner cavity of the outer casing. The upper drawer 200 and the lower drawer 300 are respectively equipped with a first panel lock and a second panel lock. The first panel lock includes a first handle 210, a first transmission mechanism, and a first locking bolt 220. The second panel lock includes a second handle 310, a second transmission mechanism, and a second locking bolt 320.

[0048] The first handle 210 and the second handle 310 have the same structure. They are set at the same angle on the outer end face of the upper drawer 200 and the lower drawer 300, and the unlocking force direction of the first handle 210 and the second handle 310 is consistent.

[0049] The first transmission mechanism is configured to convert the operation of the first handle 210 into a vertically upward locking action of the first locking tongue 220, so that the first locking tongue 220 and the first locking part 110 form a vertical lock engagement;

[0050] The second transmission mechanism is configured to convert the operation of the second handle 310 into a vertical downward locking action of the second latch 320, so that the second latch 320 and the second locking part 120 form a vertical lock.

[0051] It should be noted that this type of storage box structure, which uses an operating handle to unlock the drawer, has the following two main problems:

[0052] 1. The inconsistent shape and tilt angle of the handles disrupt the overall symmetrical aesthetics.

[0053] 2. Different drawers require opposite operations (such as lifting up and pressing down) to unlock, which increases the user's memory burden and does not conform to ergonomic principles.

[0054] The structure provided in this embodiment, based on the identical structure of the first handle 210 and the second handle 310, enables the first handle 210 and the second handle 310 to operate in the same direction through corresponding design of the first transmission mechanism and the second transmission mechanism. Compared with the prior art, it has at least the following advantages:

[0055] 1. Enhanced Appearance Consistency: By unifying the design of the handle tilt angle and operating direction of the upper and lower drawers by 300 degrees, the overall appearance of the storage box is more harmonious and beautiful, enhancing the visual consistency and industrial design sense of the product.

[0056] 2. Simplified operation logic: All drawers are unlocked using the same operation method (such as uniformly pulling up or pressing down), which avoids user confusion and memory burden caused by different directional operations in traditional designs, and improves user experience;

[0057] 3. Improve assembly and maintenance efficiency: Modular design allows for standardized production of components such as handles and latches, simplifying the assembly process and reducing maintenance difficulty, which helps to reduce manufacturing and after-sales service costs.

[0058] Preferably, the first locking part 110 and the second locking part 120 are respectively provided with a first socket and a second socket, wherein,

[0059] When the first locking tongue 220 and the second locking tongue 320 are inserted into the first socket and the second socket respectively, the upper drawer 200 and the lower drawer 300 are locked and constrained.

[0060] When the first latch 220 and the second latch 320 disengage from the first and second sockets respectively, the upper drawer 200 and the lower drawer 300 are unlocked.

[0061] The combination of the latch and the locking tongue ensures a secure connection between the drawer and the outer casing, preventing accidental opening of the drawer due to vibration or accidental contact. Furthermore, the locking tongue can be quickly disengaged from the latch via the handle linkage mechanism, enabling rapid unlocking and improving user efficiency.

[0062] In addition, compared with traditional buckle or magnetic structures, the slot-type locking method has higher anti-pry and resistance to external damage, making it suitable for storage scenarios with high security requirements.

[0063] Furthermore, the first locking tongue 220 and the second locking tongue 320 have the same structure. Both of them have an arc-shaped guide surface at the locking end. The shape of the insertion port matches the end of the locking tongue. With the arc-shaped guide surface design, it helps the locking tongue to automatically align and be smoothly inserted, thereby improving locking efficiency and stability.

[0064] Preferably, both the first handle 210 and the second handle 310 include a handle rod 211 and a handle bracket 212 connected together. A first rotating shaft 213 is installed between the handle bracket 212 and the upper drawer 200 or the lower drawer 300. The handle bracket 212 is connected to a first transmission mechanism or a second transmission mechanism. The handle bracket 212 is rotated by the handle rod 211, which in turn drives the first transmission mechanism or the second transmission mechanism to operate.

[0065] When the user operates the handle 211, it drives the handle bracket 212 to rotate around the first rotating shaft 213, thereby driving the corresponding transmission mechanism to achieve the locking or unlocking function of the latch.

[0066] The handle bracket 212 has a lifting part 2121 that protrudes outward and extends to the inner side of the panel of the upper drawer 200 and the lower drawer 300. The lifting part 2121 is separated from the first locking tongue 220 and is inserted into the clearance groove of the second locking tongue 320. The purpose of the lifting part 2121 is to cooperate with the transmission mechanism to realize the unlocking operation of the locking tongue.

[0067] Specifically, the following is a detailed description of the first transmission mechanism:

[0068] Preferably, the first transmission mechanism includes:

[0069] The first locking tongue pressure plate 230 is located inside the drawer panel, and the first locking tongue 220 is movable up and down within the space enclosed by the first locking tongue pressure plate 230.

[0070] The first spring 240 has its two ends connected to the first locking tongue pressure plate 230 and the first locking tongue 220 respectively. The first spring 240 always provides the first locking tongue 220 with elastic force toward the first locking part 110.

[0071] Guide wheel bracket 250, which is connected to first locking tongue pressure plate 230;

[0072] A fixed pulley 260 is mounted on a guide wheel frame 250 via a second rotating shaft 261;

[0073] The linkage rope 270 has one end connected to the first locking tongue 220 and the other end connected to the lifting part 2121. The linkage rope 270 is embedded in the groove of the fixed pulley 260.

[0074] The operation process is as follows: when the user operates the first handle 210, the handle bracket 212 rotates, causing the lifting part 2121 to move upward and pull the linkage rope 270. At this time, the linkage rope 270 causes the first locking tongue 220 to move downward and disengage from the first socket, completing the unlocking action of the upper drawer 200.

[0075] When the user releases the hand, the first spring 240 automatically resets and pushes the first locking tongue 220 upward, so that the first locking tongue 220 automatically inserts into the first socket, thereby automatically locking the upper drawer 200.

[0076] The linkage rope 270, in conjunction with the pulley system, enables the handle operation to be quickly transmitted to the locking tongue, improving the response speed of unlocking and locking. Meanwhile, the elasticity of the first spring 240 can achieve the automatic locking and reset of the first locking tongue 220, making the operation simple and convenient.

[0077] Specifically, the following is a detailed description of the second transmission mechanism:

[0078] The second transmission mechanism is similar to the first transmission mechanism in principle, but operates in the opposite direction.

[0079] Preferably, the second transmission mechanism includes:

[0080] The second locking tongue pressure plate 330 is located inside the panel of the lower drawer 300, and the second locking tongue 320 is movable up and down within the space formed by the second locking tongue pressure plate 330.

[0081] The second spring 340 is connected at both ends to the second locking tongue pressure plate 330 and the second locking tongue 320 respectively. The second spring 340 always provides the second locking tongue 320 with elastic force toward the second locking part 120, so that it automatically inserts into the second socket when not in operation, thereby achieving locking.

[0082] The operation process is as follows: when the user operates the second handle 310, the handle bracket 212 rotates and drives the lifting part 2121 to move upward. At this time, the lifting part 2121 can push the second locking tongue 320 upward, so that it is disengaged from the second socket, and the unlocking action of the lower drawer 300 is completed.

[0083] When the user releases the hand, the second spring 340 automatically resets and presses down on the second locking tongue 320, causing the second locking tongue 320 to automatically insert into the second slot, thereby automatically locking the lower drawer 300.

[0084] Overall, it is through the specific design of the first transmission mechanism and the second transmission mechanism that the upper drawer 200 and the lower drawer 300 can maintain the same appearance as the first handle 210 and the second handle 310, and also ensure that the two operate in the same direction.

[0085] Preferably, a gap is left between the adjacent surfaces of the upper drawer 200 and the lower drawer 300 as a clearance space, which effectively avoids mutual interference between the components during operation and ensures the stability and smoothness of the panel lock structure operation.
