Description

Technical field:

[0001] The utility model relates to the technical field of drawer assembly, in particular to a drawer back plate mounting structure. Background technology:

[0002] In the furniture industry, significant differences exist between domestic and international production dimensions. A prime example is the thickness of drawer backs. Domestic drawer backs are typically 16mm, while overseas drawer backs tend to be 18mm. This seemingly minor difference significantly impacts manufacturers during design, processing, and assembly. Especially in the context of globalized production, where manufacturers must simultaneously accommodate production of two specifications, this thickness discrepancy significantly increases the design and production complexity of multiple components.

[0003] Due to the different thicknesses of the back panels, the first thing affected is the design of the side panels and connectors connected to them. The back panels of drawers are usually fixed to the side panels by grooves or screws. The thickness of the 16mm back panel determines the location and depth of the grooves or holes in the side panels, while the 18mm back panel requires deeper or wider grooves to accommodate the increased thickness. At the same time, the precise position of the fixing holes on the side panels also needs to be readjusted according to the thickness of the back panel to ensure tightness during assembly. This means that the manufacturer needs to design and process two sets of completely different specification molds for the side panels, which not only increases the mold cost, but also places higher demands on the flexibility of the production line.

[0004] Secondly, due to the size differences of the connectors, the reserved holes for connecting the rails to the side panels need to be adjusted to account for the thickness changes. For example, the rail holes for a 16mm back panel are closer together, while the holes for an 18mm back panel are farther apart. This subtle difference forces manufacturers to produce two different sizes of connectors to accommodate both thicknesses. For efficient assembly line production, managing such a variety of parts significantly increases inventory pressure and significantly increases production costs.

[0005] This dimensional variation caused by varying back panel thickness not only poses challenges to the design and processing of individual components but also creates a chain reaction that impacts the entire drawer production process. Manufacturers must invest additional resources to design, manufacture, and manage two independent component systems, while also frequently adjusting equipment during assembly to accommodate varying production specifications. These additional steps and equipment adjustments increase production costs and reduce efficiency, issues that are particularly acute in global production, as manufacturers must meet the specifications of both domestic and international markets.

[0006] Therefore, although the difference in back panel thickness is only a detail in drawer production, it comprehensively affects all aspects of production, from the connector to the slot design of the side panels, to the matching of key components such as the slide rails. This size difference adds additional production costs to the manufacturer. Currently, most of the adjustments for drawer panels on the market are adjustments to the height and front-to-back angle of the panel. For example, the Chinese patent publication number CN218304056U describes a drawer structure that is easy to install and adjust. Currently, this type of panel adjustment solution is to adaptively adjust the height deviation of the panel, and the different back panels are often produced in two specifications at the same time, which significantly increases the manufacturer's production cost.

[0027] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0028] See Figures 1 to 7 As shown, a drawer back panel mounting structure includes a tail sealing block 1 and a back panel fixing member 3 that cooperates with the tail sealing block 1 to fix the back panel 2, wherein the tail sealing block 1 is installed at the rear end of the side panel 4, the back panel fixing member 3 is installed on the tail sealing block 1 and is formed with a mounting groove 5 for positioning the back panel 2, and the tail sealing block 1 is provided with a first positioning groove 11 and a second positioning groove 12 for positioning the back panel fixing member 3 in front and behind to adjust the width of the mounting groove 5, and the tail sealing block 1 is also provided with a first buckling hole 13 for buckling with the back panel fixing member 3 and capable of sliding back and forth; the back panel fixing member 3 is bent and provided with a first folding plate portion 31 that can be clamped in the first positioning groove 11 or the second positioning groove 12 and a second folding plate portion 32 for matching and buckling with the first buckling hole 13. By setting a first positioning groove 11 and a second positioning groove 12 distributed at intervals on the tail sealing block 1, the size of the installation slot 5 is changed by respectively snapping the back panel fixing part 3 into the first positioning groove 11 and the second positioning groove 12, so as to fix the back panels 2 of different thicknesses, so that the tail sealing block 1 and the back panel 2 and the connecting screws used for installing the back panels 2 of different thicknesses can be shared, which can reduce the production line of parts and components, reduce inventory pressure, and thus greatly reduce the production cost of the manufacturer.

[0029] The upper and lower ends of the tail seal block 1 are both provided with a first positioning groove 11 and a second positioning groove 12, and the first positioning groove 11 and the second positioning groove 12 are both in the shape of a strip and can allow the first folding plate portion 31 to slide up and down; the upper and lower ends of the back panel fixing member 3 are both provided with a first folding plate portion 31. There are two first buckle holes 13 and they are respectively located next to the two second positioning grooves 12. There are two corresponding second folding plate portions 32, and the width of the first buckle hole 13 is greater than the second folding plate portion 32, so that the back panel fixing member 3 can be adjusted forward and backward. By setting the first and second positioning grooves 11 and 12 in the shape of vertical strips and setting the width of the first buckle hole 13 greater than the second folding plate portion 32, the back panel fixing member 3 can be quickly matched and buckled onto the tail seal block 1, and the installation slots 5 of two widths can be quickly adjusted forward and backward.

[0030] The back panel fixing member 3 is L-shaped, wherein the first positioning groove 11, the second positioning groove 12 and the first buckle hole 13 are all located on one surface, and at least two first mounting holes 33 for mounting the back panel 2 are provided on the other surface of the back panel fixing member 3.

[0031] The back panel fixing member 3 is also stamped with a plurality of spaced protrusions 34, which are coplanar with the first and second positioning slots 11, 12, and first fastening holes 13. A raised area 35 is also stamped on another surface of the back panel fixing member 3, opposite the area where the first mounting hole 33 is located. Stamping the plurality of protrusions 34 and raised areas 35 on the back panel fixing member 3 not only strengthens the back panel fixing member 3 but also provides a certain degree of elasticity, ensuring a more stable connection between the back panel fixing member 3 and the back panel 2.

[0032] The back panel fixing member 3 is also provided with a third folding plate portion 36 for locking and fixing with the tail seal block 1. The third folding plate portion 36 is bent in a direction opposite to the second folding plate portion 32, and the tail seal block 1 is provided with an elastic locking arm 14 that mates with and engages with the third folding plate portion 36. The tail seal block 1 is provided with an unlocking space 15 for the elastic locking arm 14 to swing away from the third folding plate portion 36. The elastic locking arm 14 is formed with a pressing protrusion 16 that protrudes outward and is used to bend and unlock the third folding plate portion 36. By providing the elastic locking arm 14 and the third folding plate portion 36 on the tail seal block 1 and the back panel fixing member 3, respectively, the back panel fixing member 3 is locked to the tail seal block 1 through the matching and engaging of the third folding plate portion 36 and the elastic locking arm 36. After the pressing protrusion 16 pushes the elastic locking arm 14 to swing away from the third folding plate portion 36, the back panel fixing member 3 can be removed from the tail seal block 1.

[0033] The tail seal block 1 is inserted and installed at the tail of the side panel 4, and the upper end of the tail seal block 1 is fixed to the side panel 4 by a tail seal pin 6, and the lower end of the tail seal block 1 is fixed to the side panel 4 by a screw. The interval between the first positioning groove 11 and the second positioning groove 12 is 1mm-5mm. The interval between the first positioning groove 11 and the second positioning groove 12 is 2mm. In the embodiment, the widths of the installation slots 5 are 16mm and 18mm respectively. Of course, according to actual needs, the selectivity of the installation slots 5 can be increased by increasing the number of positioning grooves or changing the spacing between the positioning grooves.

[0034] In summary, in the present invention, the first positioning slot 11 and the second positioning slot 12 are provided on the tail seal 1 to adjust the fixed position of the back panel fixing member 3, thereby varying the width of the mounting slot 5 to accommodate back panels 2 of varying thicknesses. Of course, a drawer has two side panels 4, so two sets of tail seals 1 and back panel fixing members 3 are required.

[0035] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
