[0026] As shown in Figures 1 to 3 The folding packaging box comprises a rectangular bottom tray 1, a support side bar 7 is fixedly arranged at the top of the short side of the bottom tray 1, a short side plate 2 is hingedly arranged at the top of the support side bar 7, a long side plate 3 is hingedly arranged at the top of the long side of the bottom tray 1, a connecting frame 4 is arranged at the top end of the short side plate 2, the connecting frame 4 has a turnover frame 41 hingedly arranged at the top of the short side plate 2, a connecting arm 43 is fixedly arranged on the turnover frame 41, a clamping groove 44 matched with the top of the long side plate 3 is arranged at both ends of the connecting arm 43, and the clamping groove 44 is detachably fixedly connected with the top of the long side plate 3. An angle blocking piece 8 matched with the short side plate 2 and the long side plate 3 is fixedly arranged outside the four corners of the bottom tray 1. In this embodiment, the bottom of the long side plate 3 is hingedly arranged with the bottom tray 1, and the short side plate 2 is hingedly arranged with the bottom tray 1, which has higher connection strength than insertion and will not be separated during transportation when subjected to vibration and bumping, thereby ensuring transportation safety. The angle blocking piece 8 provides support for the long side plate 3 and the short side plate 2 outside, the clamping grooves 44 at both ends of the connecting arm 43 in the connecting frame 4 are connected with the top of the two long side plates 3, respectively, thereby providing support between the top ends of the long side plate 3 and the short side plate 2, and ensuring the stability of the long side plate 3 and the short side plate 2. When idle, the clamping groove 44 and the long side plate 3 can be separated, and the long side plate 3 and the short side plate 2 are folded on the bottom tray 1 in sequence, thereby reducing the space occupation when idle. The support side bar 7 provides support for the short side plate 2 at the bottom thereof, and a certain height of space is reserved for the support side bar 7 when it is bent.

[0027] In some embodiments, the outer side of the clamping groove 44 is vertically screwed with a hand nut 45, and the top of the long side plate 3 is provided with a through hole matched with the hand nut 45. By rotating the hand nut 45, the hand nut 45 is inserted into the through hole, so that the clamping groove 44 and the long side plate 3 are fixedly connected. By pulling out the hand nut 45 from the through hole, the clamping groove 44 and the long side plate 3 can be separated.

[0028] In some embodiments, the top of the short side plate 2 is provided with a clearance notch 21 matched with the turnover frame 41, and the two ends of the clearance notch 21 are fixedly provided with a hinge seat 42. One end of the turnover frame 41 is rotatably connected with the hinge seat 42. When the packaging box is used, the turnover frame 41 is turned and embedded into the inside of the clearance notch 21, so as to connect the clamping groove 44 and the top of the long side plate 3. When the packaging box is empty, the short side plate 2 is folded towards the bottom tray 1, and the turnover frame 41 is also turned outwards and abuts against the outer side of the short side plate 2.

[0029] In some embodiments, the long side plate 3 has a lower plate body 31 hingedly connected with the bottom tray 1, and an upper plate body 32 is hingedly connected with the top of the lower plate body 31. A support is arranged between the upper plate body 32 and the lower plate body 31. When the height of the long side plate 31 is large, the long side plates 31 on both sides of the bottom tray 1 will intersect when folded, which affects the flatness after folding. Therefore, the long side plate 3 is arranged as the hingedly connected upper plate body 32 and lower plate body 31. When the packaging box is used, the support 6 supports between the upper plate body 32 and the lower plate body 31, so that it remains in an upright state. When the packaging box is empty and folded, the support 6 no longer provides support, and the upper plate body 32 can be folded on the outside of the lower plate body 31.

[0030] In some embodiments, as shown in Figure 1 and 3 , the support 6 has a sliding groove 61 fixedly arranged on one side of the upper plate body, and an insertion slot 62 corresponding to the sliding groove 61 is fixedly arranged on the lower plate body 31. An insertion plate 63 is slidably arranged in the inside of the sliding groove 61 and the insertion slot 62. The outer side of the insertion slot 62 is provided with a fixing bolt 65 for locking or releasing between the insertion slot 62 and the insertion plate 63. When the packaging box is used, the insertion plate 63 is inserted into the inside of the insertion slot 62, and the insertion plate 63 supports between the insertion slot 62 and the sliding groove 61, so that the upper plate body 32 and the lower plate body 31 are prevented from being bent. The insertion slot 62 and the insertion plate 63 are locked by the fixing bolt 65, so that the stability of the support is not affected by the movement of the insertion plate 63 during use. When the packaging box is empty and folded, the insertion plate 63 is pulled out of the insertion slot 62, so that the support between the upper plate body 32 and the lower plate body 31 is no longer provided.

[0031] In some embodiments, the top of the insertion plate 63 is fixedly provided with a limiting strip 64, which facilitates the upward pulling of the insertion plate 63.

[0032] In some embodiments, the top of the short side plate 2 and the long side plate 3 are provided with a pad 31, the thickness of the pad 31 is the same as the thickness of the connecting arm 43, when the present packaging box is stacked in up-down, the pad 31 on the lower packaging box cooperates with the connecting arm 43 to support the upper packaging box.

[0033] In some embodiments, the top of the short side plate 2 and the long side plate 3 are provided with a pad 31, the thickness of the pad 31 is the same as the thickness of the connecting arm 43, when the present packaging box is stacked in up-down, the pad 31 on the lower packaging box cooperates with the connecting arm 43 to support the upper packaging box.

[0034] In some embodiments, the corner blocking piece 8 is a corner joint plate fixedly arranged outside the corner of the bottom tray 1.

[0035] In some embodiments, the side of the long side plate 3 and the short side plate 2 are detachably fixedly connected through the connecting bolt 9; when the packaging box is used, the long side plate 3 and the short side plate 2 are assembled and fixed through the connecting bolt 9, further improving the stability of the long side plate 3 and the short side plate 2.

[0036] So far, the embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.

[0037] The above-described embodiments only express some implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
