[0007] In a preferred embodiment of the utility model, it also includes a sliding block, a spiral spring and a pull rod. The sliding block is installed at the end of the waterproof curtain, the spiral springs are symmetrically arranged on both sides of the winding roller, and the pull rod is installed on the side of the sliding block.

[0008] In a preferred embodiment of the utility model, a clamping frame is also included. The clamping frame is installed on the side of the box body, and the clamping frame is movably clamped with the pull rod.

[0009] In a preferred embodiment of the utility model, it also includes a support frame and a placement frame. A plurality of support frames are installed in the box body, and the placement frames are arranged in the support frames.

[0010] In a preferred embodiment of the utility model, it also includes corner protection pads, and the corner protection pads are installed around the bottom of the box.

[0011] In a preferred embodiment of the utility model, a protective sleeve is also included, and the outer side of the pull rod is wrapped with the protective sleeve.

[0012] Compared with the prior art, the utility model has the following advantages: after the goods are placed in the box, the cover seals the top of the box, the waterproof shell prevents water from entering from the bottom and sides, and the waterproof curtain moves along the guide frame from the side to cover the top of the box to prevent moisture from entering the box from the top, thereby achieving a waterproof effect.
