Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a fuse box with a sealing structure. Background Art

[0002] In automobiles, fuse boxes are usually used to install and protect automobile fuses to ensure the safety of vehicle circuits. Fuse boxes need to have excellent electrical properties, mechanical strength and high temperature resistance. In addition, in order to ensure the effective operation of the fuse box, the sealing structure is also one of the key elements. The sealing structure can prevent impurities such as moisture and dust from entering the fuse box, thereby improving the reliability and durability of the fuse box. With the continuous development of automobile technology, the requirements for the sealing performance and safety performance of fuse boxes are also getting higher and higher. Therefore, the technology of fuse boxes with sealing structures is also constantly improving and improving. For example, the use of high-performance plastic materials and high-precision manufacturing processes can improve the sealing performance and mechanical strength of the fuse box; the use of high-temperature resistant materials and fire prevention measures can improve the safety performance of the fuse box.

[0003] In the process of realizing the utility model, the inventor found that the prior art had the following problems: 1. The existing fuse box has a female buckle on the box cover, and the bottom box is connected to the male buckle. The buckle is directly buckled to close the fuse box. The buckle is easy to break after a long period of opening and closing, and there is no other closed structure inside, which makes the sealing of the fuse box poor; 2. The existing fuse box does not have a concave bottom box inner layer in the shape of a mouth. When the lid is closed, the inner layer of the bottom box cannot be inserted into the box cover, resulting in a gap between the bottom box and the box cover, affecting the sealing. In addition, the bottom box of the existing fuse box does not have a telescopic structure, which makes installation and removal very inconvenient. Utility Model Content
