Description

Technical Field

[0001] The utility model belongs to the technical field of household articles and relates to a foldable storage box, in particular to a bottom plate positioning structure of the foldable storage box. Background Art

[0002] Storage boxes are widely used in daily life and business activities. Traditional storage boxes are fixed structures that take up a large amount of storage space when not in use. With the increasing demand for space efficiency and living space constraints, the drawbacks of traditional storage boxes are becoming increasingly apparent. Furthermore, traditional storage boxes take up a large amount of space during transportation, increasing transportation costs.

[0003] For this purpose, people have proposed folding storage boxes with various structures, such as the folding storage box recorded in Chinese patent literature (application number 202120941975.X). The side walls of this storage box are flipped relative to the bottom plate to achieve folding or unfolding.

[0004] Another example is the foldable storage container and foldable box-type push-pull cart described in Chinese patent literature (Application No. 202321081116.3). The bottom panel of this storage box flips relative to the front and rear side walls, and the front and rear side walls move closer or further apart when the left and right side walls are folded or unfolded. When the storage box is folded, the bottom panel is located between the folded left and right side walls and the front or rear side wall. During transportation, the bottom panel can still swing, colliding with other components and generating noise. During the folding and unfolding process, the bottom panel can also swing arbitrarily, affecting the smoothness of the folding and unfolding operation. Summary of the Invention

[0005] The utility model proposes a bottom plate positioning structure for a foldable storage box. The technical problem to be solved by the utility model is how to improve the smoothness of the folding and unfolding operations of the foldable storage box and avoid noise generated during transportation of the foldable storage box.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions: a foldable storage box bottom plate positioning structure, the foldable storage box includes a rigid side wall, a bottom plate and a foldable side wall that can be folded and unfolded, an edge of the bottom plate is rotatably connected to a rigid side wall by an axis, the bottom plate is horizontally arranged when the foldable storage box is in the unfolded state, and the bottom plate is vertically arranged when the foldable storage box is in the folded state; it is characterized in that the foldable storage box bottom plate positioning structure includes an elastic hook and an abutment seat installed on the rigid side wall, when the bottom plate is set vertically, one plate surface of the bottom plate contacts the abutment seat, and the hook surface of the elastic hook contacts the other plate surface of the bottom plate.

[0007] Compared with the existing technology, this foldable storage box forms a bottom plate positioning structure for positioning the bottom plate in a vertical state by installing elastic hooks and abutment seats on the rigid side walls, which significantly reduces the possibility of the bottom plate swinging randomly and making noise during transportation of the foldable storage box; and significantly reduces the possibility of the bottom plate swinging randomly and affecting the folding and unfolding operations during folding and unfolding.

[0008] The bottom plate positioning structure of this foldable storage box boasts a simple structure and low manufacturing costs. When the bottom plate is flipped from a horizontal to a vertical position, the elastic hook is forced to deform, and the bottom plate is inserted between the hook surface and the seat. When the bottom plate is flipped from a vertical to a horizontal position, the bottom plate and the elastic hook can be separated by gently pressing the hook surface to separate it from the bottom plate, or by simply flipping the bottom plate to force the hook to deform. This provides the advantage of convenient operation.

[0009] In the above-mentioned foldable storage box bottom plate positioning structure, the rigid side wall includes two oppositely arranged side wing connecting parts and an end plate part; elastic hooks are installed on the two side wing connecting parts, and the two elastic hooks are oppositely arranged.

[0010] In the above-mentioned bottom plate positioning structure of the foldable storage box, the abutment seats are installed on the end plate portion, there are two abutment seats, and the abutment seats are arranged in a one-to-one correspondence with the elastic hooks.

[0011] In the above-mentioned bottom plate positioning structure of the foldable storage box, the abutment seat is in the shape of an elongated strip and is arranged in the vertical direction.

[0012] In the above-mentioned bottom plate positioning structure of the foldable storage box, the rigid side wall, the abutment seat and the elastic hook are connected as a whole and are made of plastic.

[0013] In the above-mentioned folding storage box bottom plate positioning structure, the folding storage box also includes a group of intermediate connecting frames, and the intermediate connecting frames are connected to the two rigid side walls through a group of folding side walls. There are two bottom plates, and one edge of one bottom plate is connected to a rigid side wall through an axis rotation, and one edge of the other bottom plate is connected to the intermediate connecting frame through an axis rotation; the bottom plate and the intermediate connecting frame can also be connected through a second bottom plate positioning structure; the second bottom plate positioning structure includes an elastic hook and an abutment seat installed on the vertical frame part. When the bottom plate is set vertically, one plate surface of the bottom plate contacts the abutment seat, and the hook surface of the elastic hook contacts the other plate surface of the bottom plate.

[0014] In the above-mentioned folding storage box bottom plate positioning structure, the middle connecting frame includes two oppositely arranged vertical frame parts, both of which are equipped with elastic hooks and abutment seats. The vertical frame parts, abutment seats and elastic hooks are connected as a whole and are made of plastic. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the present invention, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; they may refer to direct connection or indirect connection through an intermediate medium; they may refer to internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0029] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0030] like Figure 1 As shown, the foldable storage box includes two rigid side walls 1, two bottom plates 2, two sets of foldable and unfoldable foldable side walls 3 and a set of intermediate connecting frames 4; the intermediate connecting frames 4 are connected to the two rigid side walls 1 through a set of foldable side walls 3. Figures 1 to 9As shown, one edge of one bottom plate 2 is rotatably connected to a rigid side wall 1 via an axis, and one edge of another bottom plate 2 is rotatably connected to an intermediate connecting frame 4 via an axis; when the foldable storage box is in the unfolded state, the bottom plate 2 is horizontally arranged, and when the foldable storage box is in the folded state, the bottom plate 2 is vertically arranged.

[0031] The rigid side wall 1 includes two oppositely arranged side wing connecting parts 1a and an end plate part 1b. The bottom plate positioning structure of the folding storage box includes an elastic hook 5 installed on the side wing connecting part 1a of the rigid side wall 1 and an abutment seat 6 installed on the end plate part 1b. The rigid side wall 1, the abutment seat 6 and the elastic hook 5 are connected as a whole and made of plastic. This structure can simplify the structure and reduce manufacturing costs. Elastic hooks 5 are installed on both side wing connecting parts 1a, and the two elastic hooks 5 are arranged opposite each other. Figure 4 As shown, when the base plate 2, connected to the rigid side wall 1, is vertically positioned, one surface of the base plate 2 contacts the abutment seat 6, while the hook surface of the elastic hook 5 contacts the other surface of the base plate 2. The elastic hook 5 and the abutment seat 6 maintain the base plate 2 in its vertical position. The elastic hook 5 has a guide bevel. When the base plate 2 rotates from a horizontal position to a vertical position, the base plate 2 automatically passes over the hook portion of the elastic hook 5 via the guide bevel. When the base plate 2 switches from a vertical position to a horizontal position, the base plate 2 can be directly moved to force the base plate 2 to separate from the elastic hook 5. The abutment seat 6 is elongated and arranged vertically. There are two abutment seats 6, one for each elastic hook 5. This structure ensures that both the left and right edges of the base plate 2 are positioned, improving the bottom surface's positioning stability and reducing the possibility of deformation of the base plate 2, which may prevent it from fitting easily into the elastic hook 5.

[0032] The bottom plate 2 and the intermediate connecting frame 4 can also be connected through a second bottom plate positioning structure; the structure and principle of the second bottom plate positioning structure are the same as those of the above bottom plate positioning structure, and only the different parts are described here. The intermediate connecting frame 4 includes two oppositely arranged vertical frame parts 4a, and both vertical frame parts 4a are equipped with elastic hooks 5 and abutment seats 6. The vertical frame parts 4a, abutment seats 6 and elastic hooks 5 are connected as a whole and are made of plastic. Figure 9 As shown, when the base plate 2 connected to the middle connecting frame 4 is set vertically, one surface of the base plate 2 contacts the abutment seat 6, and the hook surface of the elastic hook 5 contacts the other surface of the base plate 2; the elastic hook 5 and the abutment seat 6 keep the base plate 2 in a vertical setting state.
