DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] refer to Figures 1 to 5 :

[0023] Embodiment 1: The utility model discloses an aviation box with a hinged cover structure, comprising a box body 100, wherein the upper end of one side of the box body 100 is rotatably mounted with a box cover 200 through a hinged structure 300, and the other end of the box cover 200 is locked and unfolded with the other side of the box body 100 through a locking structure 400. Specifically, the box body 100 is a hexahedral structure, having four side panels, a bottom panel at the bottom, and a box cover 200 (cover panel) at the top, wherein the side panels are further divided into long side panels and short side panels. Normally, the box cover 200 is hinged to the long side panels on one side, and a locking structure 400 is installed with the long side panels on the other side. Specifically, the hinge structure 300 includes an upper hinge 1, a lower hinge 2 and a hinge shaft 3, wherein the upper end of the upper hinge 1 is fixedly connected to the box cover 200, the lower end of the upper hinge 1 extends downward and forms an upper hinge hole 121 at the end, the lower end of the lower hinge 2 is fixedly connected to one side of the box body 100, the upper end of the lower hinge 2 extends upward and is fixedly connected to the end of the box body 100. The lower hinge hole 221 is formed in the upper hinge hole 121, and the hinge shaft 3 passes through the upper hinge hole 121 and the lower hinge hole 221 at the same time and is interference fit on one side. The box cover 200 and the box body 100 are also provided with a pulling member 500 for controlling the expansion angle of the box cover 200 on the side close to the hinge structure 300. One end of the pulling member 500 is connected to the box cover 200 and the other end is connected to the box body 100. Specifically, the upper hinge 1 is located on both sides of the lower hinge 2, and the hinge shaft 3 is connected to the upper hinge holes 121 on both sides. 1 Interference fit, the interference fit here means that there is a difference between the diameters of the two hinge holes and the diameter of the hinge shaft 3. In this embodiment, the diameter of the upper hinge hole 121 is smaller than the diameter of the hinge shaft 3, and the diameter of the hinge shaft 3 is smaller than the diameter of the lower hinge hole 221, that is, the lower hinge hole 221 is located in the middle, and can better rotate relative to the middle section of the hinge shaft 3. Since the diameter of the upper hinge hole 121 is smaller than the diameters of both ends of the hinge shaft 3, it needs to be installed in the form of thermal expansion and contraction or direct injection molding.

[0024] Embodiment 2: The lower hinge 2 is located on both sides of the upper hinge 1 and both sides of the hinge shaft 3 and is interference fit with the lower hinge hole 221. The difference between this embodiment and embodiment 1 is that the interference fit portion becomes the lower hinge hole 221, and the upper hinge hole 121 is located in the middle, and ultimately rotation is performed through the upper hinge hole 121 as a rotating hole.

[0025] Specifically, unlike the installation method of traditional hinge-type metal parts, here, there is no need to install by screwing, because drilling screw holes on the fireproof board will easily loosen after subsequent installation. Here, the upper hinge 1 includes an upper embedded part 11 and an upper hinge part 12, wherein the upper hinge hole 121 is located at the upper hinge part 12, and the upper embedded part 11 is embedded in one side of the box cover 200. The lower hinge 2 includes a lower embedded part 21 and a lower hinge part 22, wherein the lower hinge hole 221 is located at the lower hinge part 22, and the lower embedded part 21 is embedded in one side of the box body 100. Here, the embedded installation can be pre-embedded in the mold and then injection molding of the long side panel of the box cover 200 or the box body 100 is performed, or an embedded groove is set at the corresponding position of the long side panel of the box cover 200 or the box body 100, and the corresponding embedded part is placed in the embedded groove, and then installed by thermal bonding or chemical bonding.

[0026] Specifically, the upper embedded part 11 includes a top embedded groove 111 and a first side anti-slipping piece 112, and a top card groove 201 and a first side anti-slipping groove 202 are respectively provided on one side of the box cover 200 corresponding to the positions of the top embedded groove 111 and the first side anti-slipping piece 112. The top embedded groove 111 and the top card groove 201 cooperate with each other for embedded or bonded, and the first side anti-slipping piece 112 and the first side anti-slipping groove 202 cooperate with each other for embedded or bonded, and the lower embedded part 21 includes a second side anti-slipping piece 211, and a second side anti-slipping groove 101 is provided on one side of the box body 100 corresponding to the position of the second side anti-slipping piece 211, and the second side anti-slipping piece and the second side anti-slipping groove cooperate with each other for embedded or bonded.

[0027] Specifically, the first side anti-slip component 112 and the second side anti-slip component 211 are both T-shaped clips. With this arrangement, there are both lateral supporting force and longitudinal supporting force in each direction, and one side of the first side anti-slip component 112 and the second side anti-slip component 211 is provided with an anti-slip edge 1a, which can enhance the fixing ability of the box body 100 or the box cover 200 and the corresponding embedded part.

[0028] Specifically, the pulling member 500 includes a first rotating piece 51 and a second rotating piece 52, a lower pulling groove 102 is provided on one side of the box body 100, and an upper pulling groove 203 is provided on one side of the box cover 200, one end of the first rotating piece 51 is hinged to the side wall of the lower pulling groove 102, and the other end is hinged to the second rotating piece 52, and the other end of the second rotating piece 52 is hinged to the side wall of the upper pulling groove 203.

[0029] Specifically, the first rotating plate 51 and the second rotating plate 52 are both L-shaped rotating plates.

[0030] Specifically, the locking structure 400 is a butterfly padlock (existing technology), one end of which is installed on one side of the box cover 200 and the other end is installed on the other side of the box body 100.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
