The plurality of first mounting holes correspond to the plurality of second mounting holes. A bolt assembly is penetrated through the first mounting holes and the second mounting holes. The bolt assembly includes a screw rod. The screw rod sequentially passes through the second mounting hole and the first mounting hole from the outside of the box board. A limiting cap is welded to one end of the screw rod, and one side of the limiting cap is in contact with one side of the corner protector board. A fastening nut is threadedly connected to the outer surface of the screw rod, and a pressing cap is welded to one end of the fastening nut. One side of the pressing cap is in contact with the inner side of the box board.

[0006] Further, a crease groove is provided on the inner side of the box board.

[0007] Further, the corner protector board is of an L-shaped structure, and the pressing cap is of a frustum structure.

[0008] Further, a plurality of first anti-slip ridges are provided on one side of the limiting cap, and a plurality of second anti-slip ridges are provided on one side of the pressing cap.

[0009] Further, a bottom cover is provided at the bottom of the box board.

[0010] Further, a top cover is provided at the top of the box board.

[0011] The beneficial effects of the utility model are:

[0012] By setting the first mounting holes at the interfaces of the box boards, only one corner guard and bolt assembly are used in combination, and the formed packaging box can be bolted together, replacing the original slot connection where eight corner guards were glued around the box. On the premise of ensuring good strength, it can reduce the use of materials and save labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1 - 5, an assembling carton connection structure for an electrical device, comprising a box board 1 and a corner guard board 2. An indentation groove 102 is provided on the inner side of the box board 1. A plurality of first mounting holes 101 are respectively formed on both sides of the box board 1. A plurality of second mounting holes 201 are respectively formed on both sides of the corner guard board 2. The plurality of first mounting holes 101 correspond to the plurality of second mounting holes 201. A bolt assembly 3 is penetrated through the first mounting holes 101 and the second mounting holes 201. The bolt assembly 3 includes a screw rod 301. The screw rod 301 sequentially passes through the second mounting hole 201 and the first mounting hole 101 from the outside of the box board 1. A limit cap 302 is welded to one end of the screw rod 301, and one side of the limit cap 302 is in contact with one side of the corner guard board 2. A fastening nut 305 is threadedly connected to the outer surface of the screw rod 301, and a pressing cap 304 is welded to one end of the fastening nut 305. One side of the pressing cap 304 is in contact with the inner side of the box board 1.

[0021] Wherein, the corner guard board 2 is an L-shaped structure, the pressing cap 304 is a frustum structure. A plurality of first anti-slip ridges 303 are provided on one side of the limit cap 302. A plurality of second anti-slip ridges 306 are provided on one side of the pressing cap 304. The first anti-slip ridges 303 and the second anti-slip ridges 306 can prevent the bolt assembly 3 from loosening, improving the stability of the assembled box board. A bottom cover 4 is provided at the bottom of the box board 1, and a top cover 5 is provided at the top of the box board 1.

[0022] The working principle of this embodiment: When in use, first fold the box board 1 into a box body along the indentation groove 102, then align the plurality of second mounting holes 201 on the corner guard board 2 with the plurality of first mounting holes 101 on the box board 1, and then pass the screw rod 301 on the bolt assembly 3 through the second mounting hole 201 and the first mounting hole 101. The limit cap 302 at one end of the screw rod 301 will closely adhere to one side of the corner guard board 2, and then rotate the fastening nut 305 on the screw rod 301, so as to drive the limit cap 302 to be in contact with the inner side of the box board 1, thereby connecting the interface between the corner guard board 2 and the box board 11 together. Wrap the corner guard board 2 at the interface and connect it with the bolt assembly 3, then snap the bottom cover 4 to the bottom of the box board 1, snap the top cover 5 to the top of the box board 1, and finally pack it with a packing belt or stretch film.
