Description

Technical Field

[0001] This utility model relates to the field of hardware technology, specifically to an anti-tipping interlocking device for a drawer cabinet. Background Technology

[0002] A chest of drawers is a cabinet composed of multiple drawers used for storing and organizing items. Chests of drawers are widely used in homes, offices, warehouses, and other places, maximizing storage space through their design. The drawers typically open or close using a sliding mechanism, making it convenient for users to access and store items. Chests of drawers are made from various materials, including metal and wood, and different materials vary in appearance, durability, and price.

[0003] When multiple drawers of a chest of drawers are opened simultaneously, the overall center of gravity of the chest of drawers shifts. The center of gravity of the chest of drawers may have been designed to be relatively stable, but after the drawers are opened, especially when there are items inside, the weight at the front of the chest of drawers increases significantly, causing the center of gravity to shift forward. This shift in the center of gravity reduces the stability of the chest of drawers, making it more prone to tipping over. In daily life, there are often incidents of chest of drawers tipping over and injuring people due to multiple drawers being opened at the same time, which poses a significant safety hazard and causes serious trouble for users.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 This utility model discloses a drawer cabinet anti-tipping interlocking device, including a C-shaped groove 1, a locking block 2, a connecting rod 3, and a mounting plate 4. Several sets of locking blocks 2 are provided on one side of the C-shaped groove 1, and one end of the locking block 2 extends into the interior of the C-shaped groove 1. The interior of the C-shaped groove 1 is provided with connecting rods 3 located at the top and bottom of the locking blocks 2. The locking block 2 includes a sliding locking block main component 21 and a sliding secondary locking block 22. A swing hook 23 is rotatably provided on one side of the sliding locking block main component 21. The mounting plate 4 is located on one side of the locking block 2, and a driving pin 41 for driving the swing hook 23 is provided on one side of the mounting plate 4.

[0025] Specifically, a fixed pressure plate 11 is provided at one end of the C-shaped groove 1, and the connecting rod 3 at the other end is fixed by self-tapping screws.

[0026] In this embodiment, the fixed pressure plate 11 is located at the top of the C-shaped groove 1. After the connecting rod 3 inside the bottom of the C-shaped groove 1 is fixed, when the lock block 2 is opened, the connecting rod 3 above the lock block 2 will be pushed in sequence, so that the uppermost connecting rod 3 abuts against the sliding stop block 12 and compresses the spring 13. The space for the connecting rod 3 to move upward can only be used to open one set of lock blocks 2. When it is necessary to open other lock blocks 2, the currently opened lock block 2 must be closed before other lock blocks 2 can be opened.

[0027] Specifically, a sliding stop 12 is slidably provided on one side of the C-shaped groove 1, and the sliding stop 12 is connected to the fixed pressure plate 11 by a spring 13.

[0028] In this implementation scheme, the sliding block 12 is compressed by the connecting rod 3, causing the locking block 2 to open. A drawer lock can be added later. After the drawer lock is installed and locked, the sliding block 12 is locked and cannot move, so the connecting rod 3 cannot move and all the locking blocks 2 cannot be opened. After the drawer lock is unlocked, only one set of locking blocks 2 can be opened at the same time. When opening another set of locking blocks 2, the currently opened locking blocks 2 must be closed again. In actual application, multiple drawers can only be opened one at a time, which effectively prevents the danger of the cabinet tipping over due to the simultaneous opening of multiple load-bearing drawers, making it safer to use.

[0029] Specifically, an unlocking channel is provided between the main sliding lock block 21 and the secondary sliding lock block 22.

[0030] In this embodiment, when the mounting piece 4 is pulled by the drawer, the drive pin 41 at one end of the mounting piece 4 abuts against the unlocking channel between the sliding lock block main piece 21 and the sliding secondary lock block 22, opening the channel. The sliding lock block main piece 21 moves upward, causing the connecting rod 3 and the latch above it to move upward, so that the uppermost connecting rod 3 pushes up the sliding stop block 12 to compress the spring 13, thus opening the unlocking channel.

[0031] Specifically, the inside of the swing hook 23 is provided with a drive groove 24 that is movably engaged with the drive pin 41.

[0032] In this embodiment, when the mounting piece 4 is pulled along with the drawer, the drive pin 41 moves the swing hook 23 through the drive groove 24, causing the swing hook 23 to swing.

[0033] Specifically, a positioning pin 25 is provided on one side of the swing hook 23, and an arc-shaped notch 26 is provided on the positioning pin 25 to be movably engaged with the surface of the drive pin 41.

[0034] In this embodiment, the arc-shaped notch 26 ensures the connection stability between the positioning pin 25 and the drive pin 41. When the sliding lock block main component 21 moves upward, the swing hook 23 is affected by its own center of gravity, causing the positioning pin 25 to swing downward, so that the arc-shaped notch 26 is in close contact with the drive pin 41.

[0035] Specifically, the positioning pin 25 is also provided with a straight edge notch 27 located on one side of the arc-shaped notch 26.

[0036] In this embodiment, when the mounting piece 4 is pulled along with the drawer, the drive pin 41 moves the swing hook 23 through the drive groove 24, causing the swing hook 23 to drive the positioning pin 25 into the unlocking channel. As the swing hook 23 swings, the straight edge notch 27 rotates ninety degrees, fitting perfectly with the sliding secondary lock block 22, so that the positioning pin 25 is firmly locked inside the unlocking channel, keeping the unlocking channel open, thus preventing the other lock blocks 2 from opening. When the drawer is closed, the mounting piece 4 resets, causing the drive pin 41 to pass through the unlocking channel and fit perfectly into the drive groove 24. The drive groove 24 moves the swing hook 23 upward, causing the positioning pin 25 to disengage from the unlocking channel, thus closing the unlocking channel. At this time, other drawers can be opened.

[0037] Specifically, both ends of the sliding lock block main component 21 and the sliding secondary lock block 22 are provided with guide bevels 28 located at both ends of the unlocking channel.

[0038] In this implementation scheme, the guide bevel 28 increases the entrance at both ends of the unlocking channel, which facilitates the entry of the positioning pin 25 and makes the sliding more flexible.

[0039] When in use, a set of two C-shaped grooves 1 are installed on both sides of the inner wall of the cabinet. The number of locking blocks 2 and mounting pieces 4 is the same as the number of drawers. The distance between two adjacent locking blocks 2 is related to the depth of the drawer. Mounting pieces 4 are fixed on both sides of the drawer. The mounting pieces 4 are located corresponding to the locking blocks 2. When the drawer is closed, the drive pin 41 fits together with the arc-shaped notch 26 on the positioning pin 25.

[0040] In summary, this drawer cabinet anti-tipping interlock device, when the sliding stop 12 is locked, prevents all drawers from being opened. After unlocking, only one drawer in the interlock can be opened at a time. When another drawer needs to be opened, the previously opened drawer must be closed first. This design effectively prevents the danger of the cabinet tipping over caused by opening multiple load-bearing drawers at the same time, making it safer to use. It is widely used in steel cabinets, wooden cabinets, and filing cabinets and has broad application prospects.
