The invention discloses a moisture-proof interchange box, and relates to an outdoor cross connecting cabinet. The moisture-proof interchange box comprises a box body with an air inlet and an air outlet. A shaft sleeve is arranged in the box body and provided with a first check ring and a supporting column. The supporting column is provided with a second check ring. A spring is arranged between the first check ring and the second check ring. The supporting column extends out of the box body, and the top end of the supporting column is provided with a collection groove. The lower end of the supporting column is provided with a left driven rod and a right driven rod. A first slide groove is formed in the air inlet, and a second slide groove is formed in the air outlet. A first baffle is arranged on the first slide groove, and a second baffle is arranged on the second slide groove. A first connecting rod is arranged on the first baffle and connected with the left driven rod. A second connecting rod is arranged on the second baffle and connected with the right driven rod. Compared with the prior art, the moisture-proof interchange box has the advantages that the air inlet and the air outlet can be automatically closed in rainy days, moisture can be prevented from entering the box body, and the problem that in the past, elements inside an existing interchange box are easily corroded and short-circuited in the damp environment is solved.
Description
technical field [0001] The invention relates to an outdoor optical cable transfer box. Background technique [0002] In the field of communication, the optical cable transfer box is a common communication device, which is usually used to accommodate various types of telecommunication equipment, and because the telecommunication transfer box contains a lot of telecommunication equipment, it will generate a lot of heat during operation. In order to transfer the box For heat dissipation, several air inlets and several air outlets are usually set up on the box, and the simple heat convection principle is used to let the air dissipate the heat inside the box. If the switching box is in a humid, hot and rainy environment in the south, the humidity in the air is very high, which is easy to corrode and short-circuit the telecommunication equipment inside the switching box, resulting in a decrease in the service life and transmission quality of the telecommunication equipment. Howe...
