[0032] To address the issue of poor sealing performance in existing roof boxes during practical use, which affects their long-term durability, please refer to [link / reference needed]. Figures 1-4 This embodiment provides the following technical solution:

[0033] In this embodiment, a plastic sealing strip 202 is provided at the upper end of each of the two lid connecting strips 201. The plastic sealing strip 202 includes a sealing opening 206 and an elastic plastic strip 205. The two lid connecting strips 201 are sealed together by the elastic plastic strip 205 embedded in the sealing opening 206. The roof box cover cardboard 2 at the upper end of the roof box half shell 1 is inserted into the sealing opening 206 by the elastic plastic strip 205. The plastic sealing strip 202 will undergo slight elastic deformation. This deformation makes a tight and continuous contact between the elastic plastic strip 205 and the sealing opening 206, which can effectively block air flow, prevent liquid penetration, and block dust and pollutants, providing a relatively clean internal environment.

[0034] Furthermore, two folded cardboard pieces 301 are provided on both sides of the triangular cover 3. A fold line is provided between the folded cardboard pieces 301 and the triangular cover 3, and an inner recess 302 is formed between the two folded cardboard pieces 301 and the triangular cover 3. Fold lines are provided between the triangular cover 3 and the inner sealing cardboard 101 and the outer sealing cardboard 102. An elastic sealing strip 307 is provided on the outer edge of each of the two folded cardboard pieces 301. The folded cardboard pieces 301 are sealed to the roof cover cardboard 2 by embedding the elastic sealing strip 307 between the two cover connecting strips 201. A sealing pressure strip 306 is installed at the lower end of the elastic support plate 305. The folded cardboard pieces 301 are sealed to the roof cover cardboard 2 by the sealing pressure strip 306. The roof cover cardboard 2 is sealed by the elastic sealing strip 307 at the upper end of the folded cardboard pieces 301 and the sealing pressure strip 306 on the outer side, maintaining the sealing effect, achieving a good sealing connection effect, improving the use effect, and having a simple structure that is easy to operate.

[0035] Specifically, the roof box cover cardboard 2 at the upper end of the roof box half shell 1 is inserted into the plastic seal 206 through the elastic plastic strip 205. The plastic seal 202 will undergo slight elastic deformation. This deformation makes a tight and continuous contact between the elastic plastic strip 205 and the plastic seal 206, which can effectively block air flow, prevent liquid penetration, and block dust and contaminants, providing a relatively clean internal environment. Furthermore, the roof box cover cardboard 2 is sealed by the elastic sealing strip 307 at the upper end of the folded cardboard 301 and the sealing pressure strip 306 on the outside, maintaining the sealing effect, achieving a good sealing connection effect, improving the use effect, and having a simple structure that is easy to operate.

[0036] Working principle: During use, the roof box cover cardboard 2 at the upper end of the roof box half-shell 1 is inserted into the plastic seal 206 through the elastic plastic strip 205. The plastic seal 202 undergoes slight elastic deformation. This deformation creates a tight and continuous contact between the elastic plastic strip 205 and the plastic seal 206, effectively blocking airflow, liquid penetration, dust, and contaminants, providing a relatively clean internal environment. Furthermore, the elastic sealing strip 307 at the upper end of the folded cardboard 301 and the outer sealing pressure strip 306 compress the sealed roof box cover cardboard 2, maintaining the sealing effect and achieving a good sealing connection, improving the performance. The structure is simple. For ease of operation, when opening is required, the two roof box cover cardboards 2 are separated by peeling off the plastic seal strip 202. The folded cardboard 301 is then detached from the inner wall of the roof box cover cardboard 2 by pulling out the plastic sheet insert 303, and unfolded along the fold line to open the roof box. The combination of the plastic seal strip 202 and the plastic sheet insert 203 allows the two roof box cover cardboards 2 to be opened and sealed, and the folded cardboard 301 on both sides of the triangular cover 3 can also be opened and sealed. The structure of the plastic seal strip 202 and the plastic sheet insert 203 allows for repeated use, enabling the roof box to be opened and sealed repeatedly, effectively improving the usage effect, facilitating long-term use, and increasing usability.
