[0002] A toolbox is a device used for storing, organizing, and carrying tools, widely used in various fields such as industry, home, and automotive repair. Toolboxes come in a variety of designs and materials, commonly including plastic, metal, and composite materials. Plastic toolboxes have become the mainstream choice in the market due to their advantages such as being lightweight, waterproof, moisture-proof, and reasonably priced. Existing toolboxes typically employ a modular, layered design; for example, the upper layer holds small tools such as wrenches and screwdrivers, while the lower layer holds heavier or larger items such as hammers and drills. This structure facilitates categorized storage, but in situations where multiple tools are needed in complex environments, the separate upper and lower layers prevent simultaneous access to tools, causing inconvenience. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the background technology mentioned above, and to provide a foldable storage toolbox that connects multiple storage spaces into one unit by rotation, and then connects the storage space to the box body by connecting parts. It can be unfolded horizontally for easy access to tools, or stacked vertically for storage inside the box. The structure is simple and easy to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a foldable storage toolbox, comprising a box body and a set of drawers. The front side of the box body has a pull-out opening. The outer side of the drawers and the inner wall of the box body are provided with cam grooves. A sliding component is connected between two adjacent drawers. The sliding component moves along the cam groove and is connected to the inner wall of the box body. A guide rail is connected between the box body and the drawers. The cam groove on the drawer is straight, and the cam groove inside the box body is an upwardly curved line. When the drawer moves relative to the box body along the guide rail, it always moves along the cam groove.

[0005] Furthermore, the sliding assembly includes a front cam, a connecting rod, and a rear pin connected in sequence. One end of two adjacent drawers is slidably connected to the cam groove via the front cam, and the other end is rotatably connected to the drawer via the rear pin. The two sides are symmetrically arranged so that the two adjacent drawers can be rotatably and slidably connected.

[0006] Furthermore, the adjacent surfaces of the drawers are inclined surfaces, the rear end of the front drawer is inclined downwards, the front surface is also provided with a handle, and the front end of the rear drawer is correspondingly inclined downwards.

[0007] Furthermore, the guide rail includes an outer rail, a sliding rail, and an inner rail connected in sequence. The outer rail is set on the two side walls of the cabinet and aligned with the pull-out opening. The inner rail is set on both sides of the frontmost drawer. The sliding rail is slidably connected between the outer rail and the inner rail.

[0008] Furthermore, the top surface of the box is also provided with a top cover, which is detachably connected to the box.

[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0016] Example: Figure 1-3As shown, the foldable storage toolbox of this utility model includes a box body 1 and a set of drawers 2. A pull-out opening 3 is provided on the front side of the box body 1. Cam grooves 4 are provided on the outer side of the drawers 2 and the inner wall of the box body 1. A sliding component 5 connects adjacent drawers 2, and the sliding component 5 moves along the cam groove 4 and is connected to the inner wall of the box body 1. A guide rail 6 connects the box body 1 and the drawers 2. The cam groove 4 on the drawers 2 is straight, while the cam groove 4 inside the box body 1 is an upwardly curved line. When the drawers 2 move relative to the box body 1 along the guide rail 6, they always move along the cam groove 4. The sliding assembly 5 includes a front cam 7, a connecting rod 8, and a rear pin 9 connected in sequence. One end of two adjacent drawers 2 is slidably connected to the cam groove 4 through the front cam 7, and the other end is rotatably connected to the drawer 2 through the rear pin 9. The two sides are symmetrically arranged so that the two adjacent drawers 2 can be rotatably and slidably connected.

[0017] The adjacent surfaces of drawer 2 are inclined surfaces. The rear end of the front drawer 2 is inclined downwards. The front surface is also provided with a handle 10. The front surface of the rear drawer 2 is inclined downwards accordingly.

[0018] The guide rail 6 includes an outer rail 11, a sliding rail 12, and an inner rail 13 connected in sequence. The outer rail 11 is set on the two side walls of the box 1 and aligned with the pull-out opening 3. The inner rail 13 is set on both sides of the frontmost drawer 2. The sliding rail 12 is slidably connected between the outer rail 11 and the inner rail 13.

[0019] The top surface of the box 1 is also provided with a top cover 14, which is detachably connected to the box 1. The top surface of the top cover 14 is also provided with a plug groove 15, and the bottom surface of the box 1 is also provided with a plug foot 16. Two adjacent boxes 1 are connected to the top cover 14 by the plug foot 16 for limiting.

[0020] The cam groove 4 on the inner wall of the box 1 is composed of horizontal line segments and arc-shaped line segments. The horizontal line segments and arc-shaped line segments are arranged alternately. The height difference between two adjacent horizontal line segments is greater than the height of drawer 2 but less than twice the height of drawer 2.

[0021] In practical use, taking three drawers 2 as an example, the pull-out opening 3 on the front side of the box body 1 corresponds to the size of the drawer 2. The front drawer 2 is equipped with a handle 10, a straight cam groove 4 in the middle of the side, and an inner rail 13 in the lower part of the side. The middle drawer 2 does not need to be equipped with a cam groove 4 on the side. The rear drawer 2 is equipped with a cam groove 4 in the middle of the side. The adjacent surfaces of the three drawers 2 are all downward sloping surfaces. The two adjacent drawers 2 are rotatably connected by a sliding component 5, which allows the front cam 7 to slide along the cam groove 4 to switch between the horizontal unfolded state and the vertical stacked state. The inner rail 13 is connected to the outer rail 11 through the sliding rail 12 to limit the connection between the front drawer 2 and the box body 1. The rear drawer 2 is not adjacent to the drawer 2 and does not have a sliding component 5. In order to facilitate the quick connection of the rear drawer 2 with the cam groove 4 in the box body 1, a front cam 7 is added to the middle of the side of the rear drawer 2 near the rear end, which can increase the stability when unfolding and storing.

[0022] When the toolbox is in the expanded state, refer to Figure 2 The three drawers 2 unfold in a row, and the guide rail 6 extends, limiting the maximum unfolded length of the guide rail 6 to keep the three drawers 2 closely adjacent, supported by the guide rail 6 and the cabinet 1. When storage is needed, push the drawer 2 to the right by holding the handle 10. The squeezing will cause the rear drawer 2 to move inward into the cabinet 1, and the guide rail 6 will retract inward into the cabinet 1. During the movement, the front cam 7 slides and is limited by the cam groove 4, which will guide the front cam 7 to move to the upper right curved track. There are no other changes in the straight section, but the curved section will cause the rear end of the drawer 2 to tilt upward first. The inclined structure of the drawer 2 allows the middle drawer 2 to support the front end of the rear drawer 2 to prevent the rear drawer 2 from being misaligned. As the rear end of the drawer 2 gradually moves upward, the resistance when it tilts upward will force the rear drawer 2 to move to the left, that is, squeeze the middle drawer 2, until the sliding component 5 moves. At this time, the connecting rod 8 starts to rotate with the rear pin 9 as the center and the connecting rod 8 as the radius, so that the rear drawer 2 gradually overlaps with the middle drawer 2, making the rear drawer... 2. The rear drawer 2 is kept in a near-horizontal state when climbing up the curved section by relying on the sliding component 5 at the front end and the cam groove 4 at the rear end, preventing the toolbox from falling out. Similarly, the middle drawer 2 moves into the box body 1 and remains horizontal and upward. The cam groove 4 on the side of the rear drawer 2 and the front drawer 2 allows the sliding component 5 to slide along it. The height misalignment between the drawers 2 is achieved by the rotation of the rear pin 9. Horizontal storage is achieved by the front cam 7 sliding along the cam groove 4 on the drawer 2, completing the storage of the three drawers 2. At this time, the rear drawer 2 is supported by the cam groove 4 of the box body 1 at the rear end and by the sliding component 5 in the middle. The middle drawer 2 is supported by the cam groove 4 of the box body 1 at the rear end and by the sliding component 5 at the front end. The front drawer 2 is always located on the guide rail 6 and is supported by the guide rail 6.

[0023] When the toolbox is in its stored state, refer to Figure 3The three drawers 2 are stacked, and the guide rails 6 retract, so that the three drawers 2 are horizontally positioned inside the box 1, supported by the guide rails 6 and the box 1. When it is necessary to unfold, refer to the operation and principle of storage; unfolding is the reverse process, which will not be repeated here.

[0024] This utility model uses a sliding component to connect the drawer to the box in a retractable manner. The drawer can be extended or retracted by the guide rail, so that multiple drawers can be simultaneously stored in the box or unfolded outward. When unfolded, tools are easy to access and all tools are clearly visible and easy to find and store. When stored, the drawers are stacked one on top of the other to save space and the structure is simple and easy to use.

[0025] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
