Description

Technical Field

[0001] This utility model relates to the field of drawers, specifically to an assembled drawer for a tool cabinet. Background Technology

[0002] The existing structural design of tool cabinet drawers has many limitations: traditional drawers mostly use welding or one-piece molding processes, with side panels and bottom panels fixed by welding, and drawer panels and frames forcibly locked with bolts. Some components are even integral structures that cannot be disassembled. This non-fully assembled design requires specialized welding equipment and skilled workers in the production process, increasing manufacturing costs and time; the installation process relies on welding tools or heavy-duty fastening equipment, is complex to operate, and has high requirements for the installation environment, making it difficult for ordinary users to complete on their own. Meanwhile, traditional drawer components, due to their fixed structure (such as side panels and bottom panels being vertically fixed), must maintain their three-dimensional shape during transportation. Individual drawers occupy a large space, resulting in low transport capacity and significantly increased logistics costs. Furthermore, welded joints are prone to fatigue fracture due to vibration and load, requiring complete component replacement for later maintenance, leading to high repair costs.

[0011] The following is a description of the embodiments and appendices. Figures 1-6 The technical solution of this utility model will be further described below.

[0012] Example 1 An assemblable drawer for a tool cabinet includes: a drawer flat panel 1, a back panel 2, a drawer front panel 3, and a top panel 4. The drawer flat panel 1 includes side panels 11 that can be folded inward on both sides. The back panel 2 is inserted into the rear side of the drawer flat panel 1 and fixedly connected by screws. The drawer front panel 3 is installed on the front side of the drawer flat panel 1, and the positioning piece 12 at the bottom of the drawer flat panel 1 is positioned and engaged in the groove 31 at the bottom of the drawer front panel 3. The drawer front panel 3 is then fixedly connected to the drawer flat panel 1 by screws. The top panel 4 is fixedly connected to the front side of the drawer front panel 3 by screws.

[0013] As a further preferred embodiment, the drawer panel 1 includes a bottom panel 13 and a side panel 14. The side panel 14 is symmetrically fixed to both sides of the bottom panel 13 and has bending holes 15 at the connection points. The side panel 14 has a first bending edge 141 on its front and rear sides, and the bottom panel 13 has a second bending edge 131 on its front and rear sides. The connection point between the second bending edge 131 on the rear side and the bottom panel 13 has a slot 132. The insert 21 at the lower end of the back panel 2 is inserted into the slot 132, and the back panel 2 is located inside the first bending edge 141 and the second bending edge 131 on the rear side. The drawer front panel 3 is located inside the first bending edge 141 and the second bending edge 131 on the front side. The positioning piece 12 is located at the lower end of the bottom panel 13. Function of bending holes: The bending holes at the connection between the side panel and the bottom panel are preset stress weak points, allowing the side panel to be folded inward precisely along the hole (90° vertical), replacing the traditional edge-folding process that requires manual calibration.

[0014] Bending edge function: Bending edge one of the side panel and bending edge two of the bottom panel form an "L-shaped" reinforcing structure. Bending edge one enhances the longitudinal resistance to deformation of the side panel, while bending edge two enhances the lateral load-bearing capacity of the bottom panel. Socket positioning: The socket on the back of the bottom panel and the back panel insert are a matching structure. After the insert is inserted, it restricts the left and right and up and down displacement of the back panel, providing a precise reference for screw fixing.

[0015] As a further preferred embodiment, the positioning piece 12 includes a positioning piece 121 and a positioning piece 122. The positioning piece 122 is symmetrically arranged on both sides of the positioning piece 121. The positioning piece 121 is pressed down and engaged in the groove 31 in the middle of the drawer panel 3. The positioning piece 122 is pushed open to the left and right sides and engaged in the grooves 31 on both sides of the drawer panel 3.

[0016] Positioning piece one (middle) and positioning piece two (both sides) are independent movable structures. First, by pressing down positioning piece one, it is inserted into the groove in the middle of the drawer panel to achieve longitudinal positioning; then, positioning piece two is pushed open to the sides to insert into the side grooves to complete the lateral positioning, forming a "cross" pre-fixed structure. The positioning pieces are made of metal with a certain degree of elasticity. When they are engaged, they generate a clamping force through slight deformation, so that the drawer panel and the drawer flat plate are initially attached.

[0017] As a further preferred embodiment, the back panel 2 is fixed to the bent edges 141 located on the rear and both sides by screws, and the drawer panel 3 is fixed to the bent edges 141 located on the front and both sides by screws.

[0018] like Figures 1-6 As shown, the working principle of this utility model is as follows: it adopts a fully assembled structure and achieves the connection of each component through "pre-positioning + mechanical fixing".

[0019] In the basic structure of the drawer flat panel, the side panels can be folded inward along the creases. The initial state is flat, and the folding forms a three-dimensional support on both sides of the drawer. The positioning space is created by using the bent edge on the back of the drawer flat panel. The insert at the bottom of the back panel is inserted into the slot on the bottom panel to achieve initial positioning. Then, it is fixed to the bent edge of the side panel with screws to complete the longitudinal closure. The drawer is pre-fixed laterally by engaging the positioning piece at the bottom of the drawer flat with the groove of the drawer panel, and then the drawer panel and the front bent edge of the side panel are fastened with screws to form a closed front end. The top panel serves as both a front-end decoration and reinforcement, and is directly fixed to the front of the drawer panel with screws to enhance its structural strength.

[0020] No welding equipment is required. Initial assembly can be completed by folding, plugging, and snapping. Screw fixing only requires basic tools (such as screwdrivers), which can be quickly operated by ordinary users, improving installation efficiency. The components are initially flat (drawer flat plate) or thin plate (back panel, drawer panel, etc.), which can be stacked and stored, occupying little transportation space and significantly reducing logistics costs. The fully assembled design allows for the individual replacement of damaged parts (such as replacing only the worn drawer panel), reducing maintenance costs.

[0021] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
