DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Example

[0029] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0030] Reference Figure 1-Figure 5A high-strength paper box includes a paper box body 1 and a top cover 2. The top cover 2 is located directly above the paper box body 1 and is used to seal the top of the paper box body 1. The paper box body 1 includes side panels 11, a front panel 12, a stable bracket 13, a stabilizer 14, a rotating shaft 15, and a handle 16. The stable bracket 13 includes a bottom plate 131. A plurality of side panels 11 are located on both sides of the stable bracket 13, and a plurality of front panels 12 are located on the other two sides of the stable bracket 13. The plurality of side panels 11 surround the stable bracket 13 on all sides, and the bottom plate 131 is away from the ground. A plurality of vertical bars 133 are fixedly installed on one surface, and a built-in groove 135 is opened at the lower middle end of the plurality of vertical bars 133 away from the stabilizing member 14. The vertical bars 133 are provided with rotating grooves 134 on both sides inside the built-in groove 135. The rotating shaft 15 is fixed in the rotating groove 134, and the end of the handle 16 close to the rotating shaft 15 is rotatably connected to the rotating shaft 15. The positive plate 12 includes a positive paper board 122. The positive paper board 122 is provided with a connecting groove 124 at the lower middle end of the side away from the stabilizing member 14, and the connecting groove 124 is connected to the built-in groove 135.

[0031] The size of the entire handle 16 is slightly smaller than the size of the entire built-in groove 135 , so that the entire handle 16 can be more easily and freely swung in the built-in groove 135 .

[0032] The rotating shaft 15 is fixed in the rotating groove 134 and the handle 16 is nested on the rotating shaft 15, so that the operator can insert a finger into the top of the handle 16 to rotate the handle 16 outward around the rotating shaft 15, thereby making it more convenient to take out the handle 16.

[0033] Reference Figure 4-Figure 7 Limiting plates 123 are fixedly installed on both sides of the front paperboard 122. The side of the limiting plate 123 close to the connecting groove 124 is attached to the side of the vertical bar 133 away from the built-in groove 135. The sides of the multiple vertical bars 133 away from the built-in groove 135 are provided with inner grooves 132. The inner grooves 132 are used for the installation of the side panels 11. The side panels 11 include side paperboards 113. Inserts 112 are installed on both sides of the side paperboards 113. The inserts 112 are inserted into the built-in grooves 135.

[0034] The size of the notch next to the inner groove 132 is consistent with the size of the limiting plate 123 , so that when assembling the positive paperboard 122 , the limiting plate 123 can be directly attached to the notch next to the inner groove 132 to complete the assembly of the positive paperboard 122 .

[0035] The size of the inner groove 132 is consistent with that of the insert 112 , so that when assembling the side paperboard 113 , only the insert 112 needs to be inserted into the inner groove 132 to complete the assembly of the side paperboard 113 .

[0036] Reference Figure 2 、 Figure 7 A plurality of positive oblique grooves 121 for installing the stabilizing member 14 are provided on both sides of the upper end of the side of the positive paperboard 122 away from the connecting groove 124, and a plurality of side oblique grooves 111 are provided on the upper end of the side paperboard 113 close to the positive oblique groove 121. The stabilizing member 14 is installed in the positive oblique groove 121 and the side oblique groove 111. The stabilizing member 14 includes a rib 141, a plurality of insertion blocks 142, and a plurality of connecting blocks 144. The upper end of the side facing the plurality of connecting blocks 144 is provided with an insertion groove 143. The rib 141 connects the plurality of insertion blocks 142 together, and the insertion blocks 142 are inserted into the insertion groove 143.

[0037] The size of the insert block 142 is consistent with the size of the insert slot 143 , so that when the entire stabilizer 14 is installed, the operator can simply insert the insert block 142 into the insert slot 143 to complete the installation of the entire stabilizer 14 .

[0038] The front oblique grooves 121 and the side oblique grooves 111 in the installed front paperboard 122 and the side paperboard 113 are on the same straight line, so as to facilitate the subsequent installation of the stabilizing member 14 .

[0039] The working principle of the present invention is explained below: the various mechanical structures inside the high-strength paper box are all fixed by threads unless otherwise specified. In order to observe the professional and technical features more intuitively in the figure, the bolt connections are appropriately hidden. When installing the high-strength paper box, it is necessary to first fit the limiting plates 123 in the two positive paper boards 122 into the grooves next to the corresponding inner grooves 132, and make the front end of the entire positive paper board 122 protrude, so that the communicating groove 124 is aligned with the lower end of the built-in groove 135, and then the operator directly inserts the inserts 112 of the two side paper boards 113 into the corresponding inner grooves 132 to complete the installation of the bottom and surrounding areas of the entire paper box, and then the operator inserts the insertion block 142 and the rib 141 into the two insertion grooves 143 respectively to complete the installation of the stabilizer 14, and finally the operator inserts the four installed stabilizers 14 into the four side oblique grooves 111 and the positive oblique grooves 132 respectively. The entire paper box can be installed in the slot 121. After the paper box is installed, the operator puts the items that need to be protected into the bottom plate 131, and then covers the top cover 2 to safely put the entire item into the paper box. When the operator needs to move the high-strength paper box, he only needs to insert his fingers into the upper end of the handle 16. At this time, due to the rotation shaft 15, the handle 16 will swing outward along the rotation shaft 15. Then the operator can pick up the handle 16 to move the high-strength paper box. Since the handle 16 is hidden in the built-in slot 135, the volume of the high-strength paper box will not increase. When the high-strength paper box is impacted in the middle part, the horizontal handle 16 can resist the impact, and the entire paper box is in a stable triangular shape. In this way, the entire high-strength paper box can effectively resist impacts from all directions, greatly improving the impact resistance of the high-strength paper box.

[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
