Description

Technical Field

[0001] The utility model relates to the technical field of wingspan type folding boxes, in particular to a wingspan type folding box. Background Art

[0002] Folding boxes have the advantages of light weight, small footprint, and easy assembly. They are widely used in closed-loop distribution systems such as major supermarket chains, 24-hour convenience stores, large distribution centers, department stores, and food processing.

[0003] For example, a wingspan-type folding box with the announcement number "CN220997514U" is disclosed. The wingspan-type folding box is provided with components such as limit clamps, threaded support rods, support feet and support rods. After the side panels on both sides of the folding box are unfolded, the support rods can be rotated to form the required length through the adjustment of the support feet and the threaded support rods, and then support the unfolded side panels, making the opening and use of the side panels more stable. When not in use, they can also be conveniently stored and unfolded at any time when needed, which greatly increases the convenience of use. However, when the wingspan-type folding box is in use, the folding part is not supported and relies entirely on the support between the four walls of the wingspan-type folding box. When the outer wall of the wingspan-type folding box is hit, it will deform and bend, causing damage to the objects inside, reducing the protective performance of the wingspan-type folding box, and affecting the normal use of the wingspan-type folding box. Utility Model Content

DETAILED DESCRIPTION

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

[0019] See also Figure 1-5 : In this embodiment, a wingspan-type folding box includes a bottom plate 1 and a first vertical plate 4. The four corners of the outer wall of the bottom plate 1 are respectively fixedly connected to the inner bottom of the first vertical plate 4. The lower part of the outer wall of the first straight plate 5 can be rotated inwardly through the pin shaft on the inner upper side of the first vertical plate 4. The inner upper side of the first vertical plate 4 is rotatably connected to the first straight plate 5. The outer top of the first straight plate 5 is fixedly connected to a hinge 6. The outer wall of the hinge 6 is fixedly connected to a second straight plate 7. The first straight plate 5 and the second straight plate 7 can be rotated inwardly by the hinge 6 for folding. The left and right sides of the bottom plate 1 are respectively connected to the control structure 2, and the front and back sides of the bottom plate 1 are respectively connected to the opening and closing structure 3.

[0020] The control structure 2 includes a square plate 201 and a vertical plate 202. The inner sides of the multiple square plates 201 are respectively fixed to the left and right sides of the bottom plate 1. The outer sides of the tops of the square plates 201 are fixed to the bottoms of the vertical plates 202. The inner walls of the vertical plates 202 are threadedly connected to a first screw 203. The first screw 203 is subjected to force to rotate left and right through the inner walls of the vertical plates 202. The outer side of the first screw 203 is fixed to a first handle 204. The first handle 204 facilitates driving the first screw 203 to rotate left and right. The inner side of the outer wall of the first screw 203 is threadedly connected to the outer circular opening of the first straight plate 5.

[0021] By controlling the first handle 204 in the structure 2 to rotate the first screw 203 inward through the vertical plate 202, the inner side of the outer wall of the first screw 203 is threadedly connected to the circular opening of the outer wall of the first straight plate 5. At this time, the first screw 203 will restrict the pulling of the first straight plate 5, preventing the first straight plate 5 from rotating through the pin shaft on the inner side of the first vertical plate 4, avoiding the inner rotation from pressing the object, thereby improving the protection performance of the wingspan type folding box and ensuring the normal use of the wingspan type folding box.

[0022] The front and rear sides of the second straight plate 7 are respectively rotatably connected to the second vertical plate 8, and the upper outer wall of the second straight plate 7 is subjected to force to rotate through the pin shaft on the inner lower side of the second vertical plate 8, the inner top of the second vertical plate 8 is fixedly connected to the top plate 9, and the front and rear sides of the top plate 9 are respectively fixedly connected to the bracket 10, the opening and closing structure 3 includes a door panel 301 and a second screw 302, the upper outer wall of the door panel 301 is rotatably connected to the inner wall of the bracket 10, and the upper outer wall of the door panel 301 is subjected to force to rotate through the pin shaft on the inner wall of the bracket 10, the lower outer wall of the door panel 301 is threadedly connected to the outer wall of the second screw 302, and the outer side of the second screw 302 is fixedly connected to the second handle 303, the second handle 303 facilitates the second screw 302 to rotate back and forth through the door panel 301, and the inner side of the outer wall of the second screw 302 is threadedly connected to the circular mouth of the outer wall of the bottom plate 1.

[0023] Working principle:

[0024] Wingspan folding box opening and closing:

[0025] The second handle 303 in front is made to rotate forward with the second screw 302 through the front door panel 301, so that the inner side of the outer wall of the second screw 302 is separated from the front side of the base plate 1, and then the front door panel 301 is rotated forward through the front bracket 10. At this time, the door panel 301 realizes the wingspan, and then the object is placed on the top of the base plate 1, so that the front door panel 301 rotates, and at the same time, the second handle 303 rotates the second screw 302 inward, and is connected with the corresponding round-mouth thread on the outer wall of the base plate 1.

[0026] Wingspan foldable box folding storage:

[0027] When the second handle 303 on the front and rear sides is rotated outward, the second screw rod 302 is disengaged from the circular opening of the outer wall of the bottom plate 1, and then the upper outer wall of the door panel 301 is rotated outward through the inner pin of the bracket 10. Then, the first handle 204 drives the first screw 203 to rotate outward through the vertical plate 202, so that the inner side of the outer wall of the first screw 203 is disengaged from the circular opening of the outer side of the first straight plate 5. The disengagement of the first screw 203 causes the first straight plate 5 to lose its positioning, and then the outer wall bottom of the first straight plate 5 is rotated through the inner pin of the first vertical plate 4, so that the second straight plate 7 is rotated through the inner pin of the second vertical plate 8. At the same time, the top of the first straight plate 5 and the bottom of the second straight plate 7 cooperate with the hinge 6 to rotate inward. At this time, the bottom plate 1, the first straight plate 5, the second straight plate 7 and the top plate 9 are folded. Then the folding box is turned over as a whole so that the top plate 9 faces downward, and then the door panel 301 is rotated inward to complete the overall folding of the folding box. Example 2

[0028] See also Figure 1-5 In this embodiment, a wingspan-type folding box further includes round rods 11, and the inner sides of the two round rods 11 are fixedly connected to the outer walls of the two brackets 10 respectively.

[0029] Working principle:

[0030] By holding the round rod 11 and pulling it upward, the top plate 9 can be moved upward, and the round rod 11 is convenient for driving the top plate 9 to perform lifting operations.

[0031] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
