[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0018] like Figure 1 As shown, a waterproof and sealed protective box includes: a box body 1 and a box cover 2, with an opening at the top of the box body 1. The box cover 2 fits into the opening and is detachably connected to the box body 1 by buckles 3. Preferably, there are at least four buckles 3, distributed on opposite sides of the box cover 2, with two buckles 3 on each side, and the two buckles 3 are symmetrically distributed about the center line of the box body 1.

[0019] like Figure 2 and Figure 3 As shown, the top of the housing 1 extends outward to form a top edge, and a sealing protrusion 4 is provided on the top edge. The sealing protrusion 4 is located in the middle of the top edge and extends along the top edge in a ring shape in the length direction. Preferably, the sealing protrusion 4 has a rectangular cross-section, and a groove for installing a sealing strip is provided on the top of the sealing protrusion 4.

[0020] like Figure 4 and Figure 5 As shown, a first sealing strip 5 is provided in the groove at the top of the sealing protrusion 4. The first sealing strip 5 has a circular cross-sectional shape and is elastic. The first sealing strip 5 is fixed to the top of the sealing protrusion 4 by adhesive.

[0021] A second sealing strip 15 is provided on the top edge inside the sealing protrusion 4. A groove for accommodating the sealing strip is formed in the portion of the top edge located inside the sealing protrusion 4. The second sealing strip 15 has a circular cross-section and is elastic. The second sealing strip 15 is fixed to the groove on the top edge by adhesive.

[0022] A stepped mounting platform 6 is provided on the inner wall of the housing 1. An abutment plate 7 is provided above the stepped mounting platform 6. The abutment plate 7 is connected to the stepped mounting platform 6 by elastic elements 8. The function of the elastic elements 8 is to maintain the abutment plate 7 with an upward tendency. The elastic elements 8 are springs, and there are several of them, evenly distributed along the abutment plate 7. The stepped mounting platform 6 has a mounting groove, and the elastic elements 8 are installed in the mounting groove and can be completely retracted into the mounting groove.

[0023] like Figure 3 and Figure 6As shown, an inner storage box 9 is provided above the abutment plate 7. The inner storage box 9 is located inside the box 1, and its outer wall is attached to the inner wall of the box 1.

[0024] The bottom of the inner storage box 9 abuts against the abutment plate 7, and the top extends outward to form a top eave 10. The top eave 10 can overlap with the top edge of the box body 1, and the overlap is located inside the sealing protrusion 4.

[0025] The top edge 10 has a first groove at its bottom that matches the second sealing strip 15, and a groove at its top for accommodating the sealing strip, within which a third sealing strip 11 is disposed. The third sealing strip 11 has a circular cross-section and is elastic. The third sealing strip 11 is connected to the top edge 10 by adhesive.

[0026] When no external force is applied, the top edge 10 is raised above the top of the sealing protrusion 4 by the elastic member 8. The elastic member 8 raises the abutment plate 7 and the inner storage box 9 located above the abutment plate 7, so that the top of the inner storage box 9 is higher than the top of the sealing protrusion 4, so that the inner storage box 9 can be removed.

[0027] The bottom of the lid 2 extends inward to form a bottom edge 12. A sealing groove 13 is formed on the bottom edge 12 to match the sealing protrusion 4. A second groove is formed at the bottom of the sealing groove 13 to match the first sealing strip 5. A third groove is formed on the bottom edge 12 inside the sealing groove 13 to match the third sealing strip 11.

[0028] When the lid 2 is closed with the body 1, the sealing groove 13 engages with the sealing protrusion 4, the second groove engages with the first sealing strip 5, the first groove engages with the second sealing strip 15, and the third groove engages with the third sealing strip 11, giving the protective box excellent waterproof performance.

[0029] When the lid 2 is closed with the box body, the lid 2 will press down on the inner storage box 9, causing it to descend to the top edge 10 and fit against the top edge.

[0030] A handle 14 is provided on the outer wall of the box 1 for lifting the protective box.

[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
