In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-3, the present invention provides a technical solution: a novel fast-assembling structure applied to a box cover comprises a box body 6, a cross beam 4 and an upper cover 1; mounting hole sites are arranged at the four peripheral corners of the box body 6, the cross beam 4 and the upper cover 1, when the mounting hole sites on the cross beam 4 are communicated with the mounting hole sites on the upper cover 1, the two mutually communicated mounting hole sites are connected through screws 3, sealing rings 2 are mounted on the screws 3, and the cross beam 4 is fixed on one surface of the upper cover 1 close to the box body 6 through the screws 3 with the sealing rings 2; the rear side wall of the cross beam 4 is provided with a sealing strip 5 matched with the outer side wall structure of the cross beam, and the upper cover 1 with the cross beam 4 is fixed on the box body 6 through a screw 3 and locked by a welding nut 7; the position of the cross beam 4 corresponding to the welding nut 7 is provided with a blind hole, the welding nut 7 is riveted on the blind hole, and the position of the box body 6 corresponding to the welding nut 7 is also provided with a blind hole for installing the welding nut 7.

Further, the upper cover 1 is provided with four, including the first upper cover, the second upper cover, the third upper cover and the fourth upper cover adjacent to each other from left to right, and each upper cover 1 is provided with a crossbeam 4.

Furthermore, the first upper cover is fixed on the box body 6 through screws 3, the second upper cover is fixed on a cross beam 4 of the first upper cover through screws 3, the third upper cover is fixed on the cross beam 4 of the second upper cover through screws 3, and the fourth upper cover is fixed on the cross beam 4 of the third upper cover through screws 3.

Furthermore, the second upper cover is used for a blind hole which is connected with the first upper cover and has the hole site inner diameter larger than the outer diameter of the screw 3.

Furthermore, the third upper cover is used for a blind hole which is connected with the second upper cover and has an inner diameter of a hole site larger than the outer diameter of the screw 3.

Furthermore, the third upper cover is used for a blind hole which is connected with the third upper cover and has an inner diameter of a hole site larger than the outer diameter of the screw 3.

The working principle is as follows: because there are 4 upper covers 1 in present box 6, need 3 crossbeams 4, these 3 crossbeams 4 have disturbed the installation of relevant spare part, and the customer need dismantle upper cover 1 in addition will dismantle crossbeam 4, just can put into other parts, and the human cost who causes is bigger.

The cross beam 4 and the box body 6 are further improved in structure, the cross beam 4 and the upper cover 1 are preassembled together, a user only needs to disassemble 2 screws 3 on the uppermost portion of the horizontal direction in the drawing 1 (the other 2 screws 3 preassembled on the box body 6 do not need to be disassembled), the original mode of disassembling 6 screws 3 can be replaced, the cover and the cross beam 4 can be disassembled at the same time, and a series of operations are conveniently carried out on products in the box body 6.

When the upper cover 1 needs to be disassembled without disassembling the cross beam 4, an operator only needs to disassemble the four screws 3 (the 2 screws 3 and the 2 pre-installed screws 3) corresponding to the four corners of the upper cover 1.

When the upper cover 1 and the cross beam 4 need to be disassembled, an operator firstly disassembles the upper cover 1 at the lower part of the cross beam 4 needing to be disassembled, and then disassembles the upper cover 1 at the upper part of the disassembled upper cover 1 together with the cross beam 4.

When a plurality of crossbeams 4 are dismantled to needs, then the installation from up the order of following is dismantled by one and can.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
