Description

Technical Field

[0001] This utility model relates to the field of combined folding boxes, specifically a combined folding box. Background Technology

[0002] A collapsible container is a container whose main components can be easily folded or disassembled and reassembled for reuse.

[0003] For example, a combination folding box with announcement number "CN220683070U" has a bottom plate, an extension bottom plate, and an extension upright plate. When the storage box needs to store more items, the extension bottom plate is first pulled out from the grooves on both sides of the bottom plate, and then the extension upright plate is pulled to move outward from the inside of the upright plate body, thereby increasing the storage space inside the storage box and improving the practicality of the device. However, in the use of the combination folding box, the extension parts are controlled by elastic components. When there are stones at the bottom of the combination folding box, they can easily enter the grooves, causing the locking block to move upward and disengage from the corresponding groove, resulting in the extension plate moving, reducing the stability of the combination folding box and affecting its normal use. Utility Model Content

[0004] The purpose of this invention is to address the issue of reduced stability in combined folding boxes, which affects their normal use, and to propose a combined folding box solution.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a combined folding box, including horizontal plates and insert plates. The inner walls of the two horizontal plates are slidably connected to the outer walls of the insert plates on the left and right sides respectively. A curved plate is fixed to the outer end of the insert plate. A screw is threaded to the inner wall of the curved plate. A vertical plate is rotatably connected to the bottom slots of the two horizontal plates. A folding structure is connected to the bottom of the vertical plate. A closing structure is connected to the top of the horizontal plates.

[0007] Preferably, the stacked structure includes a base plate and a straight plate. The top of the base plate is fixedly connected to the bottom of the upright plate. The inner wall of the base plate is slidably connected to the outer wall of the straight plate. A first bolt is threaded to the bottom of the straight plate. A vertical plate is fixedly connected to the end of the outer wall of the straight plate. A square plate is rotatably connected to the upper inner side of the vertical plate.

[0008] Preferably, the outer wall of the first bolt is threaded to the bottom of the base plate, and the bottom of the base plate is fixedly connected to a base at both the front and rear ends.

[0009] Preferably, a handle is fixed to the outside of the screw.

[0010] Preferably, the closed structure includes a first top cover and a second top cover, the inner wall of the first top cover is inserted into the upper part of the outer wall of the horizontal plate, the inner wall of the first top cover is slidably connected to the outer wall of the second top cover, and a second bolt is threadedly connected to the top right side of the first top cover.

[0011] Preferably, the bottom of the outer wall of the second bolt is threaded to the top round opening of the second top cover.

[0012] The present invention proposes a combined folding box with the following advantages: by rotating the first bolt downward through the base plate in the folding structure, the upper part of the outer wall of the first bolt is disengaged from the bottom round opening of the straight plate. Then, the straight plate moves outward on the inner wall of the base plate, increasing the distance between the two straight plates. Subsequently, the first bolt is rotated upward through the base plate, so that the top of the outer wall of the first bolt is inserted into the corresponding round opening at the bottom of the straight plate. This changes the original elastic control form, improves the stability of the combined folding box, and ensures the normal use of the combined folding box. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0019] Please see Figure 1-4In this embodiment, a combined folding box includes horizontal plates 1 and insert plates 4. The inner walls of the two horizontal plates 1 are slidably connected to the outer walls of the insert plates 4 on their left and right sides respectively. The insert plates 4 slide left and right through the inner walls of the horizontal plates 1 under force. A curved plate 5 is fixedly connected to the outer end of the insert plates 4. A screw 6 is threadedly connected to the inner wall of the curved plate 5. A vertical plate 8 is rotatably connected to the bottom slots of the two horizontal plates 1. The horizontal plates 1 rotate through the pins on the outer walls of the vertical plates 8 under force. A folding structure 2 is connected to the bottom of the vertical plates 8, and a closing structure 3 is connected to the top of the horizontal plates 1.

[0020] The expanded structure 2 includes a base plate 201 and a straight plate 202. The top of the base plate 201 is fixedly connected to the bottom of the vertical plate 8. The inner wall of the base plate 201 is slidably connected to the outer wall of the straight plate 202. The straight plate 202 slides left and right through the inner wall of the base plate 1 when subjected to force. The bottom of the straight plate 202 is threadedly connected to a first bolt 203. The outer end of the straight plate 202 is fixedly connected to a vertical plate 204. The upper inner side of the vertical plate 204 is rotatably connected to a square plate 205. The square plate 205 rotates through a pin on the upper inner side of the vertical plate 204 when subjected to force. The outer wall of the first bolt 203 is threadedly connected to the bottom of the base plate 201. The bottom front and rear ends of the base plate 201 are respectively fixedly connected to a base 9.

[0021] By rotating the first bolt 203 downward through the base plate 201 in the expansion structure 2, the upper part of the outer wall of the first bolt 203 is disengaged from the bottom round opening of the straight plate 202. Then, the straight plate 202 moves outward on the inner wall of the base plate 201, increasing the distance between the two straight plates 202. Subsequently, the first bolt 203 is rotated upward through the base plate 201, so that the top of the outer wall of the first bolt 203 is inserted into the corresponding round opening at the bottom of the straight plate 202. This changes the original elastic control form, improves the stability of the combined expansion folding box, and ensures the normal use of the combined expansion folding box.

[0022] A handle 7 is fixed to the outside of the screw 6, which facilitates the rotation of the screw 6. The closed structure 3 includes a first top cover 301 and a second top cover 302. The inner wall of the first top cover 301 is inserted into the upper part of the outer wall of the horizontal plate 1. The inner wall of the first top cover 301 is slidably connected to the outer wall of the second top cover 302. The second top cover 302 slides left and right through the inner wall of the first top cover 301 under force. A second bolt 303 is threadedly connected to the top right side of the first top cover 301. The bottom of the outer wall of the second bolt 303 is threadedly connected to the top round opening of the second top cover 302.

[0023] Working principle:

[0024] Combined stacking and folding box assembly installation:

[0025] The first bolt 203 is rotated downward through the base plate 201, causing the upper part of the outer wall of the first bolt 203 to disengage from the bottom round opening of the straight plate 202. Then, the straight plate 202 moves outward through the inner wall of the base plate 201, increasing the distance between the two straight plates 202. Next, the first bolt 203 is rotated upward through the base plate 201, causing the top of the outer wall of the first bolt 203 to engage with the corresponding round opening at the bottom of the straight plate 202, so that the bottom of the base 9 is in contact with the ground. Then, the square plate 205 is rotated outward through the pin shaft on the upper inner side of the vertical plate 204. Then, the insert plate 4 is pulled outward through the inner wall of the horizontal plate 1. Then, the handle 7, carrying the screw 6, rotates inward through the curved plate 5, so that the inner side of the outer wall of the screw 6 is threadedly connected to the round opening of the outer wall of the square plate 205, completing the fixing of the square plate 205 and the insert plate 4, and completing the assembly and installation of the combined folding box.

[0026] Combined stackable folding boxes for use:

[0027] The object is placed in contact with the top of the base plate 201. Then, the second bolt 303 is rotated upward through the first top cover 301, causing the bottom of the outer wall of the second bolt 303 to disengage from the top of the second top cover 302. Then, the second top cover 302 is pulled to the right along the inner wall of the first top cover 301, so that the space between the inner walls of the second top cover 302 and the inner wall of the second top cover 301 is sufficient for use. Then, the second bolt 303 is rotated downward through the first top cover 301 and connected to the corresponding round thread at the top of the second top cover 302, thus fixing the two top covers. Then, the inner walls of the first top cover 301 and the second top cover 302 are inserted into the upper part of the outer walls of the horizontal plate 1 and the square plate 205. Example 2

[0028] Please see Figure 1-4 In this embodiment, a combined folding box also includes handles 10, with the inner sides of the two handles 10 being fixedly connected to the front and rear sides of the first top cover 301, respectively.

[0029] Working principle:

[0030] By grasping the handle 10 and pulling it upwards, the first top cover 301 can be moved upwards. The handle 10 facilitates the movement of the first top cover 301.
