Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a bedside table with a concealed lock structure. Background Technology

[0002] A bedside table is a cabinet placed beside or attached to the head of the bed. Bedside tables are divided into side cabinets and main cabinets. Side cabinets are small side cabinets placed on the left and right sides of the head of the bed. Main cabinets are generally much taller than the side cabinets and are usually four to six doors, made of metal or wood, for storing and retrieving items for daily life and study, and help with the organization and placement of items.

[0003] Existing bedside tables typically do not have a lock mechanism for easy access to items. The lack of a lock means that private and valuable items can be easily seen by others, which can have negative consequences. However, adding a lock mechanism increases the need for safekeeping the mechanical key, which is small and easily lost, further affecting the user's ability to retrieve items.

[0004] Therefore, neither of the two existing technical structures mentioned above is conducive to users' flexible use of the bedside table.

[0005] To address the aforementioned issues, a bedside table with a concealed lock mechanism is proposed. Utility Model Content

[0006] The main purpose of this utility model is to provide a bedside table with a concealed lock structure, which solves the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A bedside table with a concealed lock mechanism includes a cabinet shell, which is composed of two identical cabinets, upper and lower, wherein the bottom of the lower cabinet is provided with a concealed lock mechanism.

[0009] The concealed locking mechanism includes a handwheel rotatably mounted to the bottom of the lower cabinet. A belt drive assembly is sleeved on the central shaft of the handwheel. A drive shaft is fixed inside the end of the belt drive assembly away from the handwheel. The drive shaft is rotatably mounted to the inner bottom plate of the cabinet shell through a bearing. Two sets of L-shaped locking rods are fixedly mounted on the outer wall of the drive shaft. A locking pin is abutted at one end of each set of L-shaped locking rods.

[0010] Furthermore, drawer slides are fixedly installed on both sides of the inner wall of the cabinet shell, and a drawer box is slidably arranged inside the drawer slides. A drawer baffle, which is limited by the cabinet shell, is screwed onto the outer side wall of the drawer box.

[0011] Furthermore, sliders are fixed on both sides of the bottom of the drawer box, and U-shaped groove reinforcing plates are symmetrically fixed on both sides of the bottom inside the cabinet shell, with the sliders slidingly connected to the reinforcing plates inside.

[0012] Furthermore, a sliding rod is welded between the sliders, and the top end of the locking pin is threadedly connected to the bottom end of the sliding rod.

[0013] Furthermore, a shell baffle is embedded in the back of the cabinet shell, and a spring is fixed to the inner wall of the reinforcing plate on the shell baffle. The spring extends into the interior of the reinforcing plate and makes movable contact with the outer wall of the slider.

[0014] Furthermore, a limiting post is also provided on one side of the drive shaft, which is welded to the bottom of the cabinet shell.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This invention features a concealed lock mechanism at the bottom of a traditional bedside table. A handwheel drives a belt drive assembly, which in turn rotates the drive shaft, causing two sets of L-shaped locking rods to make a quarter-circular motion. This locks the locking pins and locks the drawer. This concealed lock not only prevents unauthorized access to the bedside table, thus protecting privacy, but also eliminates the need for a mechanical key, reducing the need for key storage and preventing lost keys from hindering the user's ability to open the bedside table.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-5 As shown, this embodiment provides a bedside table with a concealed lock structure, including a cabinet shell 1, which is composed of two identical cabinets, upper and lower. The bottom of the lower cabinet is provided with a concealed lock mechanism 3. The concealed lock mechanism 3 includes a handwheel 301 rotatably mounted to the bottom of the lower cabinet. A belt drive assembly 302 is sleeved on the central shaft of the handwheel 301. A drive shaft 303 is fixed inside the end of the belt drive assembly 302 away from the handwheel 301. The drive shaft 303 is rotatably mounted to the inner bottom plate of the cabinet shell 1 through a bearing limit. Two sets of L-shaped locking rods 304 are fixedly mounted on the outer wall of the drive shaft 303. One end of the two sets of L-shaped locking rods 304 abuts against a locking pin 305.

[0026] In the above structure, the handwheel 301 is located 10cm away from the outside on the bottom surface of the lower cabinet, which is not easily seen by outsiders and is in a position that can be reached out and operated. The inner wall of the short rods of the two sets of L-shaped locking rods 304 is an arc structure, which can be easily locked onto the outer wall of the locking rod 305 when it is in contact with the locking rod 305.

[0027] Drawer slides 6 are fixedly installed on both sides of the inner wall of the cabinet shell 1. Drawer boxes 5 are slidably installed inside the drawer slides 6. Drawer baffles 2, which are limited by the cabinet shell 1, are screwed on one side wall of the outer side of the drawer box 5. When the drawer slides 6 support the drawer box 5 to slide, a 0.5cm reserved space is provided at the end to facilitate the L-shaped locking rod 304 to continue moving the drawer box 5 when it presses the locking post 305.

[0028] The drawer box 5 has sliders 9 fixed on both sides of the bottom. The cabinet shell 1 has U-shaped groove reinforcing plates 7 symmetrically fixed on both sides of the bottom. The sliders 9 and the reinforcing plates 7 are internally slidably connected. When the locking pin 305 is locked, the sliding rod 10 and sliders 9 move synchronously. The inner side wall of the reinforcing plate 7 has a groove for supporting the sliding of the sliding rod 10.

[0029] A slide rod 10 is welded between the sliders 9, and the top of the locking pin 305 is threaded to the bottom of the slide rod 10.

[0030] The back of the cabinet shell 1 is fitted with a shell baffle 4. The shell baffle 4 is aligned with the inner wall of the reinforcing plate 7 and a spring 8 is fixed thereon. The spring 8 extends into the interior of the reinforcing plate 7 and makes contact with the outer wall of the slider 9. After the slider 9 moves inside the reinforcing plate 7, it presses against the spring 8, so that the resistance between the locking pin 305 and the L-shaped locking rod 304 is maintained under the reaction force of the spring 8. At the same time, it also keeps the drawer box 5 stable in the drawer slide 6.

[0031] A limiting post 306 is also provided on one side of the drive shaft 303 and welded to the bottom of the cabinet shell 1.

[0032] The working principle of this device is as follows: When using this device, the handwheel 301 is turned from the bottom of the cabinet shell 1 with one hand. The handwheel 301 drives the transmission shaft 303 to rotate forward or backward through the belt transmission assembly 302. When rotating forward, the L-shaped locking rod 304 is locked on one side of the outer wall of the locking pin 305 by pressing against it. At this time, the slider 9 connected to the sliding rod 10 of the locking pin 305 undergoes a slight displacement in the groove of the reinforcing plate 7, while the spring 8 is compressed. Under the reaction force of the spring 8, the locking pin 305 presses against the L-shaped locking rod 304, keeping the drawer box 5 tightly in the drawer slide rail 6. At this time, both the upper and lower drawer boxes 5 are in a state where they cannot slide out of the drawer shell. Similarly, when rotating backward, the L-shaped locking rod 304 is released from the contact of the outer wall of the locking pin 305 and rotates to be aligned with the limit post 306. At this time, the drawer box 5 can be pulled out freely.

[0033] The above structure allows users to flexibly choose to lock or keep the bedside table open. The concealed lock structure also serves to prevent others from easily rummaging through the items in the bedside table. Furthermore, the concealed lock structure eliminates the need for a mechanical key, reducing the inconvenience of losing the key and being unable to open the bedside table.

[0034] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
