Detailed Description

The technical solutions of the present invention are further described below, but the scope of the claims is not limited thereto.

As shown in fig. 1, 2, 3, 4 and 5, the waterproof box provided by the utility model comprises a box body 2, a box cover 1 and a waterproof sealing strip 3, wherein a first boss 21 extending outwards is arranged on one side of the box body 2 contacting the box cover 1, a third boss 12 extends outwards from the lower edge of the box cover 1, a fourth boss 13 extends downwards from the outer edge of the third boss 12, the third boss 12 is arranged in parallel with the first boss 21, the fourth boss 13 is arranged in perpendicular to the first boss, and the waterproof sealing strip 3 is arranged at the bottom of the third boss 12.

In this embodiment, the width of the first boss 21 is smaller than the waterproof sealing strip 3, after the instrument is assembled, when the box cover 1 is connected with the box body 2 through threads or hinged, the first boss 21 extrudes the waterproof sealing strip 3, a gap is reserved between the fourth boss 13 and the first boss 21, the sealing ring is deformed after being extruded, and overflows into the gap, and at this time, the waterproof sealing strip 3 is inverted 7-shaped, so that the sealing effect is better. Be provided with sand grip 22 on the first boss 21, sand grip 22 sets up to two, and the design of sand grip 22 makes first boss 21 and the laminating of waterproof sealing strip 3 inseparabler, and preferably, the sand grip sets up to 1 or 2 or 3 or 4.

In this embodiment, the fourth boss 13 covers the first boss 21, that is, the lower edge of the first boss 21 is higher than the lower edge of the fourth boss 13 or the lower edge of the first boss 21 is flush with the lower edge of the fourth boss 13, when the waterproof box is installed in a side-placed manner, rainwater cannot enter the gap between the box body 2 and the box cover 1. The fourth boss 13 is provided with a drain hole 4, the drain hole 4 is arranged below the waterproof sealing strip 3, when the waterproof box is inversely installed according to actual needs, rainwater is gathered between the fourth boss 13 and the first boss 21, and the drain hole 4 can drain rainwater. The lower edge of the first boss 21 is provided with a chamfer, and the slope formed by the chamfer can play a role in draining accumulated water during use.
