[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a foldable cardboard box, such as Figures 1-6 As shown, the foldable carton includes a base plate 1, a folding groove 101 is provided in the middle of the bottom end of the base plate 1, and a folding component 2 is provided at the top of the base plate 1.

[0029] The folding assembly 2 includes multiple corner strips 201 fixedly connected to the four corners of the top of the base plate 1. A first vertical plate 202 is rotatably connected to the outer wall of one of the corner strips 201. Multiple rubber rods 203 are fixedly connected to the end of the first vertical plate 202. Ball heads 204 are fixedly connected to the end of the rubber rods 203. A second vertical plate 205 is rotatably connected to the outer wall of one of the corner strips 201. Multiple snap-fit ​​holes 206 are opened on the outer wall of the second vertical plate 205 at the ball head 204. Horizontal bending assemblies 3 for auxiliary folding are provided on both sides of the top of the base plate 1.

[0030] The transverse bending assembly 3 includes a horizontal plate 301 symmetrically fixedly connected to the top of the base plate 1. The outer wall of the horizontal plate 301 is provided with a transverse folding groove 302, and the side wall of the horizontal plate 301 near the base plate 1 is provided with a rectangular folding groove 303 for folding the horizontal plate 301 to the outer wall of the base plate 1.

[0031] The outer wall of the second vertical plate 205 is provided with a groove 102 at the ball head 204. The inner wall of the groove 102 is provided with a slider 103 for sliding limit. The slider 103 is fixedly connected with a locking rod 104. The ball head 204 is provided with a locking hole 105 corresponding to the locking rod 104.

[0032] Specifically, the folding groove 101 at the bottom of the base plate 1 facilitates folding the base plate 1 when folding the carton. The folding groove 101 prevents excessive creases on the cardboard wall. The folding assembly 2 allows for quick folding of the carton's side walls. Using the corner strip 201 at the top of the base plate 1, the first vertical plate 202 and the second vertical plate 205 on its outer wall are rotated, causing them to separate. The rubber rod 203 and the ball head 204 at the end of the first vertical plate 202 disengage from the snap-fit ​​hole 206. Since the ball head 204 is made of soft material, it deforms when passing through the snap-fit ​​hole 206, thus engaging and disengaging. The corner strip 201 provides longitudinal support to the opened carton, preventing damage to the side walls when loading and unloading items, and also facilitates folding the carton. To prevent damage to lower cartons from the weight of upper cartons during stacking, a horizontal bending component 3 is installed. When the vertical plates are folded, the horizontal plate 301 can be easily folded to the side of the bottom plate 1 through the horizontal folding groove 303 on the outer wall and the rectangular folding groove 302. This improves folding efficiency and reduces the floor space after folding. When the cartons are needed, the first vertical plate 202 and the second vertical plate 205 are engaged, and then the slider 103 inside the slide groove 102 drives the locking rod 104 inside the slider 103 to engage with the locking hole 105 inside the ball head 204, further improving the tightness of the vertical plate connection. Through the cooperation of the above components, the material of the cartons themselves can be used for folding, avoiding unnecessary creases during folding and improving folding efficiency.

[0033] A first L-shaped retaining strip 106 is fixedly connected to the bottom end of the base plate 1. A stop strip 107 is fixedly connected to the top end of the first L-shaped retaining strip 106. A second L-shaped retaining strip 108 is fixedly connected to the bottom end of the base plate 1 on the side away from the first L-shaped retaining strip 106. A stop groove 109 is fixedly connected to the top end of the second L-shaped retaining strip 108.

[0034] A top plate 110 is provided at the top of the base plate 1, and a triangular groove 111 is fixedly connected to the inner side wall of the top plate 110. A triangular clip 112 is fixedly connected to the outer wall of the horizontal plate 301 at the triangular groove 111.

[0035] The outer wall of the horizontal plate 301 is provided with a handle hole 113 for easy handling of the carton, and a number of protruding balls 114 for easy handling are fixedly connected to the top of the handle hole 113.

[0036] Specifically, when the base plate 1 is folded, the first L-shaped locking strip 106 and the second L-shaped locking strip 108 at the bottom of the base plate 1 are engaged, and the stop strip 107 and the stop groove 109 are further engaged. This can speed up the folding efficiency of the base plate 1 and prevent the folded base plate 1 from becoming loose during handling, making it easier for operators to handle and improving the service life of the carton. The triangular groove 111 on the inner side wall of the top plate 110 and the triangular locking strip 112 on the outer wall of the horizontal plate 301 are quickly engaged. After the carton is loaded with goods, when the top plate 110 is closed, the engagement ensures a tight connection between the top plate 110 and the carton body. The handle hole 113 on the outer wall of the horizontal plate 301 facilitates handling by operators. The protruding ball 114 at the top of the handle hole 113 cushions the operator's hands during handling, preventing fatigue after long-term handling.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
