Multifunctional miniaturized test box

The utility model relates to a multifunctional miniaturized test box, which is provided with a first test chamber and a second test chamber which are communicated in parallel, and a connecting frame arranged between the first test chamber and the second test chamber, a rotating door is assembled in the connecting frame, and a carrying bracket is arranged on the rotating door; the object carrying bracket rotates along with the rotating door to realize conversion of the test chamber on a plane; the rotary door is simple in structure and convenient to implement and maintain, tests without environments are achieved by rotating the rotary door between the first test chamber and the second test chamber in a reciprocating mode, and the first test chamber and the second test chamber independentlyprovide different test environments, so that the environment alternating time of the same test chamber is reduced, and losses are reduced; and the product instantaneous change environment test can berealized, and the test eff
