Description

Technical Field

[0001] The present application relates to the technical field of furniture, and more specifically, to a side panel structure and a drawer. Background Art

[0002] A drawer is usually composed of a bottom panel and side panels, which are mainly fixed by screws. The side panels are usually fixed on both sides of the bottom panel or on both sides of the upper part of the bottom panel. If the side panels are fixed on both sides of the bottom panel, the overall width of the drawer is increased; if the side panels are fixed on both sides of the upper part of the bottom panel, the capacity of the drawer is reduced. Therefore, the setting of the thickness of the side panels is crucial.

[0003] In order to coordinate the overall width and capacity of the drawer, the thickness of the side panels is theoretically as thin as possible. During use, when the drawer is overloaded or frequently opened and closed, the side panels will be deformed. The common solution on the market is to increase the thickness of the side panel material and add ribs on the upper edge of the product. Increasing the thickness and adding ribs can improve the rigidity and strength of the side panels and prevent the side panels from deforming when subjected to force, but it increases the material cost and causes defects such as excessive weight of the side panels.

[0037] For ease of understanding, the drawer in the embodiment of the present application is described below. Figure 1, an embodiment of the drawer in the embodiment of the present application includes: a bottom plate, a front plate, a rear plate and a side plate 1, two side plates 1 are provided and are parallel to each other; the front plate, the rear plate and the two side plates 1 are respectively arranged around the bottom plate and enclosed with the bottom plate to form a receiving chamber, the receiving chamber is used to receive objects, and the drawer is installed on the cabinet body through the guide rail. In this embodiment, the side plate 1 is made of metal material, the front plate and the rear plate are parallel to each other, and the left and right ends of the front plate and the rear plate are respectively fixedly connected to the side plates 1, the left and right side edges of the bottom plate are respectively installed on the two side plates 1, and the side plates 1 are installed on the slide rails through the guide rail fasteners 163 to drive the drawer to slide and cooperate with the cabinet body to facilitate the opening and closing of the drawer.

[0038] See also Figure 2 and Figure 3 In an embodiment of the present application, a side panel 1 structure includes: a side panel body 11 and a mounting plate 16. The length direction of the side panel body 11 is consistent with the length direction of the mounting plate 16, and the length of the mounting plate 16 is the same as the length of the side panel body 11. The side panel body 11 and the mounting plate 16 are fixedly connected. In order to reduce the possibility of deformation of the side panel 1 due to excessive load or frequent opening and closing of the drawer, and to enhance the strength of the side panel body 11, the side panel body 11 is provided with a first bending portion 12, a second bending portion 13 and a third bending portion 14. The first bending portion 12 and the second bending portion 13 are located at the two side edges of the side panel body 11 along the length direction, that is, at the upper and lower edges of the side panel body 11.

The first connecting plate 111 and the second connecting plate 113 are parallel to each other, and the first connecting plate 111 and the second connecting plate 113 are parallel to the front panel and the back panel. Further, the first connecting plate 111 is provided with a first through hole 1112 for screws to pass through. The screws pass through the first through hole 1112 and are fixedly connected to the front panel to realize the assembly of the side panel 1 and the front panel; similarly, the second connecting plate 113 is provided with a second through hole 1131 for screws to pass through. The screws pass through the second through hole 1131 and are fixedly connected to the back panel to realize the assembly of the side panel 1 and the back panel.

[0041] See also Figure 4 and Figure 5 The first connecting plate 111 is provided with a convex bump 1111, and the side plate body 11 is provided with a surface cover 112. In this embodiment, the first connecting hole 1611 is provided at the convex bump 1111, and the surface cover 112 is engaged with the convex bump 1111 to cover the first through hole 1112 and the screw, thereby enhancing the aesthetic effect of the drawer. Specifically, the convex hump 1111 is provided with a card slot 1113, and the side wall of the card slot 1113 is provided with a positioning groove 1114; the surface cover 112 is provided with a first undercut 1121 and a second undercut 1122, the first undercut 1121 is located in the card slot 1113 and is engaged with the card slot 1113, and the second undercut 1122 is located in the positioning groove 1114 and is engaged with the positioning groove 1114. By utilizing the height difference formed by the convex hump 1111, the first undercut 1121 and the second undercut 1122 provided on the surface cover 112 are respectively placed in the card slot 1113 and the positioning groove 1114 of the first connecting plate 111, thereby realizing the quick installation of the surface cover 112.

[0042] See also Figure 3 and Figure 4The mounting plate 16 is provided with a bearing portion 161 and a covering portion 162. The bearing portion 161 is provided at one side edge of the mounting plate 16 close to the ground plane along the length direction, and the covering portion 162 is provided at one side edge of the mounting plate 16 far from the ground plane along the length direction. The covering portion 162 and the bearing portion 161 are integrally formed with the mounting plate 16. In this embodiment, the bearing portion 161 is located at the lower edge of the mounting plate 16, and the bearing portion 161 is formed by bending the lower edge of the mounting plate 16 toward the middle axis of the drawer in an L-shape, and the bearing portion 161 is used to connect with the bottom plate to install the bottom plate; the covering portion 162 is located at the upper edge of the mounting plate 16, and the covering portion 162 is formed by bending the upper edge of the mounting plate 16 toward the middle axis of the drawer in an L-shape, and the edge of the covering portion 162 extends toward the inside of the drawer to cover the edge of the bottom plate at the connection with the mounting plate 16. When the wood board is not cut straight, the cracked surface is large, or the bending angle of the side panel 1 is large, looking down from the front of the drawer, there is an obvious gap between the side panel 1 and the bottom panel, and the L-shaped bend of the covering portion 162 can cover the cutting defects on the edge of the bottom panel.

[0043] See also Figure 4 In order to achieve the sliding fit between the drawer and the cabinet, the bearing part 161 is provided with a connection hole 1611 for connecting with the guide rail fastener 163, and a screw is passed through the connection hole 1611 to connect with the guide rail fastener 163. Further, the edge of the connection hole 1611 is provided with a countersunk head 1612 that is easy to bend, such as Figure 6a As shown, Figure 6a 1611 is a cross-sectional view of the connection hole 1611 without a screw installed. When the screw passes through the connection hole 1611, the screw presses against the countersunk head 1612. After the screw is fixedly connected to the guide rail fixture 163, the top surface of the screw is lower than the end surface of the bearing portion 161 connected to the bottom plate. Figure 6b As shown, Figure 6b It is a cross-sectional schematic diagram of a connection hole 1611 with a screw installed, and the screw and the countersunk head 1612 are used to quickly achieve the effect of screw countersunk hole.

[0044] See also Figure 7 In this embodiment, the countersunk head 1612 is formed by setting an easy-folding line on the edge of the connecting hole 1611. The top of the screw applies a force to the connecting hole 1611, so that the countersunk head 1612 is bent under the action of the easy-folding line, so that the connecting hole 1611 becomes a countersunk hole. The setting of the countersunk head 1612 can save the process of producing countersunk holes. On the other hand, the setting of the countersunk head 1612 makes the bottom plate fit with the bearing part 161 when the bottom plate is located on the bearing part 161, thereby avoiding the bottom plate and the bearing part 161 from being unable to fit together due to the protrusion of the screw, thereby affecting the appearance of the bottom plate.

[0045] See also Figure 4In this embodiment, two connection holes 1611 form a group, and two groups of connection holes 1611 are provided, and the two groups of connection holes 1611 are provided along the length direction of the mounting plate 16 to adapt to the connection of different types of guide rails. Users can selectively install according to different usage requirements. For example, when the user uses a 2-section slide rail with an adjustment screw, such as Figure 8a As shown, the guide rail fixture 163 moves to a group of connection holes 1611 far from the end of the side panel 1, and the screws penetrate the connection holes 1611 and connect with the fixtures, thereby installing the side panel 1 to the guide rail; when the user uses a 3-section slide rail with an adjustment screw, as shown in FIG. Figure 8b As shown, the guide rail fixture 163 moves to a group of connection holes 1611 close to the end of the side panel 1, and screws pass through the connection holes 1611 to connect with the fixture, thereby installing the side panel 1 to the guide rail.

[0046] See also Fig. 9 Furthermore, the second connecting plate 113 is provided with a socket 1132, which is used to be plugged into the guide rail hook so that the side panel body 11 can be installed on the guide rail, thereby enhancing the installation stability of the side panel 1 and the guide rail and reducing the possibility of the drawer being detached from the guide rail during opening and closing.
