Description

Technical Field

[0001] The present technical solution relates to the technical field of folding boxes, and in particular to a folding box with a storage function. Background Art

[0002] Folding boxes are indispensable in people's daily lives. Folding boxes have many functions, such as storage boxes, storage baskets, storage cabinets, etc., all of which are used to accommodate items, classify items and save storage space. Making the folding box have other multi-functions is also a problem that technical personnel in this field need to solve, such as adding rollers, cover plates and other structures.

[0003] Chinese patent CN220843382U discloses a folding box, which has the following disadvantages:

[0004] 1. When the extension board is opened, it is suspended outside the box, and its center of gravity falls outside the box. When the items are placed, there is a risk of breakage at the connection between it and the closing board. After the items are placed, the overall center of gravity deviates from the box, and the stability of the folding box cannot be guaranteed.

[0005] 2. The overall structure of the folding box is relatively complex, with many components, and the production and installation process is relatively complicated. Summary of the invention

[0006] The purpose of this technical solution is to provide a foldable box with a storage function, which solves the problem of complex structure of the original storage box and unstable center of gravity when opened by means of a separately arranged box body and cover plate and a cover plate that can be folded or laid flat.

[0007] The purpose of this technical solution is achieved in this way:

[0008] A folding box with a storage function, comprising: a box body, which has an opening; and a cover plate, which comprises a support plate 1 and a support plate 2 that are hinged to each other and are used to close the opening; wherein, the cover plate has a folded state and a flat state, when the support plate 1 and the support plate 2 are interlocked, the cover plate is in the folded state, and when the support plate 1 and the support plate 2 are opened to be parallel, the cover plate is in the flat state; a plurality of positioning blocks 1 are provided at the four corners on the outer surface of the support plate 1; when the cover plate is placed on the box body in a folded state, the positioning block 1 abuts against the four corners of the opening; positioning blocks 2 are provided on the inner surfaces of the support plate 1 and the support plate 2; when the cover plate is placed on the box body in a flat state, the positioning block 2 abuts against the four corners of the opening, so that the cover plate is located at the center of the opening.

[0009] Preferably, at least one mounting portion is provided on the inner surface of the support plate one, and a fixing block is movably provided in the mounting portion; at least one fixing portion is provided on the inner surface of the support plate two; when the cover plate is in a flat state, the end of the fixing block is pushed to be inserted into the through groove of the fixing portion to maintain the flat state of the support plates one and two.

[0010] Preferably, the inner surfaces of the support plate 1 and the support plate 2 are recessed to form a receiving space; when the cover plate is in a folded state, the positioning block 2 is placed in the receiving space.

[0011] Preferably, a plurality of positioning blocks three are provided on the inner surface of the support plate two; when the cover plate is in a folded state, the positioning blocks three are placed in the accommodating space.

[0012] Preferably, at least one snap-in block 1 is provided on the inner surface edge of the support plate 1, and at least one snap-in block 2 is provided on the inner surface edge of the support plate 2; when the cover plate is in a folded state, the snap-in block 2 is placed in a snap-in groove formed in the snap-in block 1.

[0013] Preferably, a buffer portion 1 is provided on the inner surface of the support plate 1, and a buffer portion 2 is provided on the inner surface of the support plate 2; when the cover plate is in a folded state, the buffer portion 1 abuts against the buffer portion 2.

[0014] Preferably, staggered grids are formed in the accommodating space.

[0015] Preferably, a snap-fitting portion is provided on the outer surface of the support plate 1, and a hook is provided on the side wall of the box body; when the cover plate is in a folded state, the cover plate is fixed to the box body through the snap-fitting portion and the hook.

[0016] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0017] 1. The cover plate and the box body of the technical solution are designed to be separated. The cover plate can be directly removed manually and then items can be placed in the box body. After the items are placed, the opening can be closed by the cover plate. Items can also be placed on the cover plate. When there are many items to be placed, the cover plate can be manually opened to make it flat. At this time, the cover plate has a larger bearing area. Regardless of whether the cover plate is in a folded state or a flat state, the position design of the positioning block 1 and the positioning block 2 can make the cover plate be in the center of the opening, which can increase the stability of the cover plate placed at the opening.

[0018] 2. The fixing block in the installation part designed in the technical solution can enter or exit the through slot of the fixing part. When the fixing block enters the through slot, the flat state of the cover plate can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a folding box with a storage function includes a box body 1 and a cover plate 2. The box body 1 and the cover plate 2 are independently arranged. The top surface of the box body 1 has an opening, and a person can put items into the box body 1 after removing the cover plate 2; the cover plate 2 is arranged at the opening and can close the opening of the box body 1 to prevent the items in the box body 1 from spilling, and the person can also place the items on the cover plate 2.

[0026] Furthermore, in order to increase the functionality of the folding box, we design the cover 2 into a double-layer form, so that the cover 2 has a folded state and a flat state, and the cover 2 is used to carry goods when it is placed on the box body 1 in a flat state or a folded state; the cover 2 includes a support plate 1 3 and a support plate 2 4 that are hinged to each other, and when the support plate 1 3 and the support plate 2 4 are buckled together, the cover 2 is in a folded state, and when the support plate 1 3 and the support plate 2 4 are opened to be parallel, the cover 2 is in a flat state. The cover 2 in the flat state has a larger load-bearing area and can hold more items.

[0027] like Figure 1-4As shown, a plurality of positioning blocks 5 are arranged on the outer surface of the support plate 3. When the number of the positioning blocks 5 is set to four, the four positioning blocks 5 are distributed at the four corners of the support plate 3, and their positions are adapted to the size of the opening of the box body 1. When the cover plate 2 is placed on the box body 1 in a folded state, the positioning blocks 5 abut against the four corners of the opening to fix the cover plate 2. In order to ensure the stability of the cover plate 2 when it is placed on the box body 1 in a flat state, it is necessary to place the center of the cover plate 2 at the center of the box body 1. Therefore, positioning blocks 6 are arranged on the inner surfaces of the support plates 1 and 2. When the cover plate 2 is placed on the box body 1 in a flat state, the positioning blocks 6 abut against the four corners of the opening to fix the cover plate 2. At this time, the cover plate 2 is in the center position of the top surface of the box body 1.

[0028] like Figure 3 As shown, in order to ensure the stability of the cover plate 2 in the flat state, at least one mounting portion 7 is provided on the inner surface of the support plate 3, and a fixing block 8 is movably provided in the mounting portion 7; at least one fixing portion 9 is provided on the inner surface of the support plate 2 4, and both the mounting portion 7 and the fixing portion 9 are arranged close to the hinge of the support plate 1 3 and the support plate 2 4, and a through groove 10 is opened in the fixing portion 9, and the fixing block 8 is movably placed in the through groove 10. When the cover plate 2 is in the flat state, the end portion 8 of the fixing block is pushed into the through groove 10 to maintain the flat state of the support plate 1 3 and the support plate 2 4.

[0029] Furthermore, in order to ensure that the cover plate 2 has a thinner thickness and fits tightly with the support plates 1 3 and 2 4 in the folded state, a receiving space 11 is provided in the inner surface recess of the support plates 1 3 and 2 4; when the cover plate 2 is in the folded state, the positioning block 2 6 is placed in the receiving space 11, and at the same time, a plurality of positioning blocks 3 12 are provided on the inner surface of the support plate 2 4; when the cover plate 2 is in the folded state, the positioning block 3 12 is placed in the receiving space 11, and the positioning block 3 12 is arranged in alignment with the positioning block 1 5.

[0030] Furthermore, staggered grilles 18 are formed in the accommodating space 11, and the grilles 18 can increase the physical strength of the cover plate 2 so that it can carry heavier objects.

[0031] like Figure 3 As shown, in order to ensure the stability of the cover plate 2 in the folded state, at least one clamping block 13 is provided on the edge of the inner surface of the support plate 3, and at least one clamping block 2 14 is provided on the edge of the inner surface of the support plate 2 4; when the cover plate 2 is in the folded state, the clamping block 2 14 is placed in the clamping groove 15 formed in the clamping block 13, which can ensure that the support plate 1 3 and the support plate 2 4 will not be separated due to gravity.

[0032] Furthermore, support plate 1 3 and support plate 2 4 are hinged by at least one hinge, and a buffer portion 16 is provided on the inner surface of support plate 1 3, and a buffer portion 2 17 is provided on the inner surface of support plate 2 4; when the cover plate 2 is in a folded state, buffer portion 16 abuts against buffer portion 2 17, and buffer portion 16 and buffer portion 2 17 can be set as rubber pads.

[0033] like Figure 2 As shown, a clamping portion 19 is provided on the support plate 3, a hook 20 is provided on the side wall of the box body 1, and the cover plate 2 is fixed to the box body 1 through the clamping portion 19 and the hook 20. When it is necessary to place items in the box body 1, the cover plate 2 can be placed on the side wall of the box body 1, which provides convenience for placing items.

[0034] like Figure 4 As shown, the front end face of the box body has a hinged door panel, and a button for controlling the opening of the door panel is provided. When the button is pressed, the upper end of the door panel is separated from the front end face of the box body, and the door panel is flipped open from top to bottom. At the same time, the front end face of the box body has a window for placing objects. When the door panel is opened, objects can be placed into the box body through the window. In addition, the front end face of the box body can also be directly pulled open from the side.
