Description

Technical Field

[0001] The present invention relates to a stable assembly structure for a furniture drawer, specifically a structure that can achieve stable assembly when the front panel of the furniture drawer is assembled from multiple panel members. Background Art

[0002] Chinese Patent Document No. CN111955963A discloses an improved furniture drawer assembly structure on November 20, 2020. It includes side panels, a front panel, and a rear panel. The front and rear ends of the side panels are integrally bent with front bending parts and rear bending parts respectively, and a supporting part is integrally formed or separately arranged at the lower part. The supporting part is integrally formed or separately arranged downward with a relying part. An assembly plate member and a notch part are also provided on the side panel. The assembly plate member is located inside the notch part and is fixedly arranged on the side panel. When the above-mentioned front panel is assembled, it can be fixedly arranged on the front bending part or the front side wall of the side panel by means of clamping, or fixing parts, or pasting parts, or magnetic attracting parts. In actual use, in order to improve the assembly stability of the front panel and at the same time reduce production and assembly costs, the front panel usually uses fixing parts for assembly. That is, when the fixing parts are assembled, one end will act fixedly on the front bending part, and the other end will act fixedly on the front panel. When the fixing parts act fixedly on the front panel, it will cause openings on the front panel; for medium and large-sized front panels assembled from multiple panel members, when the fixing parts are assembled, it is very easy to act on the assembly position of the front panel, resulting in cracking of the front panel. In the lightest case, it affects the appearance of the front panel, and in the worst case, it causes the front panel to be unable to be used normally or fall off from the side panel during use, seriously affecting the assembly stability of the front panel and the use safety of users. Therefore, it is necessary to further improve. Summary of the Invention

[0024] Through the improvement of the above structure, the present invention has the following advantages compared with the prior art:

[0025] 1. The front bending parts are integrally bent on the inner sides of the front ends of the left and right side plates, and connecting parts are separately arranged through the front bending parts. Then, fastening parts for assembling the front plate are arranged on the connecting parts. The fastening parts are located on the outer sides of the left and right side plates, are independently arranged from the front bending parts, and form a distance therebetween. Therefore, even when the front plate is assembled by multiple plate parts, the front plate can be stably assembled by arranging fixing parts on the fastening parts. At the same time, the fixing parts can be far away from the assembling position of the front plate during the fixing process, effectively avoiding the assembling position of the front plate, and further avoiding the disadvantages caused by the situation in the prior art that the front plate is only assembled with the front bending part directly through the fixing parts, and the fixing parts easily act on the assembling position of the front plate during assembly, resulting in cracking of the front plate, so as to improve the assembling stability of the front plate.

[0026] 2. Left and right supporting parts are respectively arranged at the lower parts of the left and right side plates, a left and right base is arranged between the left and right supporting parts, and a positioning part is arranged on the left and right base. Then, side positioning parts are respectively arranged at both ends of the front and rear crossbar telescopic components of the placing device, and a positioning matching part is arranged on the side positioning parts, so that the placing device can be longitudinally positioned and disassembled and assembled on the positioning part through the positioning matching part; because there is a longitudinal positioning and guiding effect between the positioning matching part and the positioning part, there is a certain pre-assembly effect during the assembly of the placing device. Therefore, the placing device can be disassembled and assembled conveniently, quickly, efficiently and flexibly, avoiding the problems of difficult assembly and inconvenient operation caused by the situation in the prior art that the placing device can only be accurately assembled by manually adjusting the position multiple times or having to remove the front plate without any auxiliary components, so as to facilitate the disassembly, assembly and daily maintenance of the placing device.

[0027] 3. The device is placed on the placing area of the placing device in a supported manner, so that the gravity of the device can act well on the left and right side plates and the left and right slide rail components through the placing device, which can not only improve the load-bearing capacity of the device, but also avoid the problems of fracture damage or falling during its operation, so as to ensure the placing stability of the device. Moreover, users can also disassemble and assemble the placing device at will according to actual use requirements to improve the user experience.

[0028] 4. The longitudinal and transverse dimensions of the placing area can be adjusted through the cooperation of the front, middle and rear crossbar telescopic components, the front, middle and rear movable parts, and the upper and lower connecting rods. Furthermore, devices of different sizes and / or the same size can be randomly positioned and placed on the placing areas of different sizes and / or the same size and / or different positions, so as to meet the various placing requirements of various devices, effectively avoiding the problems in the prior art that the drawer size is fixed and only devices of a single size can be placed or the placing position is fixed, so as to improve the placing flexibility of the device and provide great convenience for users to place the device.

[0029] 5. The two ends of the front and rear crossbar telescopic components are respectively assembled in a fixed manner, and the middle position can achieve lateral sliding. Therefore, the lateral dimension of the entire placing device can be adjusted, so that the placing device can be applied to drawers with different inner widths, thereby improving the flexibility and application range of the placing device.

[0030] 6. The middle crossbar telescopic component can slide longitudinally between the front and rear crossbar telescopic components. This not only enables the placing device to accommodate devices with different depths, but also allows the middle crossbar telescopic component to slide longitudinally when disassembling and assembling multiple devices, so as to adjust the position for the disassembly and assembly of the remaining devices, facilitating the use of users.

[0031] Generally speaking, it has the characteristics of simple and reasonable structure, fast, convenient and stable assembly, low manufacturing cost, good concealment and stability of device placement, wide use range, high flexibility, etc., and has strong practicability.
