Sheet metal structure capable of being quickly assembled and disassembled

The utility model relates to a sheet metal structure capable of being assembled and disassembled quickly. A fixing structure is arranged on one side of a fixed part. A buckle is fixed on the fixed part; the structure that the buckle is clamped on the fixing structure has the advantages of being convenient to disassemble and install, and solves the problems that metal plate structural parts, needing to be assembled, disassembled and replaced, of an existing environment test box are generally fixed in the modes of hidden buckles, screw locking, gluing and the like, operation is tedious, construction is difficult, certain difficulty exists in production, a mold opening mode is adopted, and the cost is low. The effect that the screw cannot be seen and used is achieved; in the prior art, the technical problems of troublesome maintenance, disassembly and assembly, poor attractiveness, high mold opening cost, single and fixed variety size and inflexible use exist. 本实用新型涉及一种快装卸的钣金结构，采用在被固定件的一侧设置固定结构；在被固定件上固定卡扣；在固定结构上
