DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment: A moisture-proof distribution cabinet, such as Figure 1-6 As shown, it includes a cabinet 1, a protective door panel 2, a rainproof ceiling 3, a mounting frame 4, a wire management trough frame 5, a mounting plate 6, an exhaust fan 7, an isolation net 8, a placement net frame 9, an air pump 121 and an air cushion ring tube 122. A wire inlet hole is opened at the front side of the bottom of the cabinet 1, and a wire outlet hole is opened in the middle of the right side wall of the cabinet 1. The front part of the cabinet 1 is connected with the protective door panel 2 through a hinge, and the top of the cabinet 1 is provided with a rainproof ceiling 3 by bolt connection. The middle of the left and right side walls of the cabinet 1 are both provided with mounting frames 4 by screw connection. The wire management trough frame 5 is evenly installed between the two mounting frames 4 from top to bottom. Mounting plates 6 are evenly spaced apart from top to bottom between the mounting frames 4, and there is an interval between the mounting plates 6 and the cable management trough frames 5. A plurality of exhaust fans 7 are installed on the top of the cabinet 1 by screw connection, and an isolation net 8 is installed on the rear side of the bottom of the cabinet 1. An interlayer is provided inside the isolation net 8, and a mesh frame 9 is slidably provided inside the interlayer. The adsorption material placed in the mesh frame 9 is activated carbon. An air pump 121 is fixedly connected to the bottom of the cabinet 1, and an air cushion tube 122 is provided around the protective door panel 2. The material of the air cushion tube 122 is rubber, and the air pump 121 is connected to the air cushion tube 122 through a pipeline.

[0022] like Figure 2 and Figure 6 As shown, it also includes a placement mechanism 11, which includes a placement slot frame 111, a limit rod 112 and a reset spring 113. The placement slot frames 111 are fixedly connected to the middle of the left and right side walls of the cabinet 1 by screws, and a U-shaped limit rod 112 is horizontally slidably arranged on the upper part of the placement slot frame 111. The two support rods of the limit rod 112 and the placement slot frame 111 are connected with a reset spring 113.

[0023] When in use, the staff places the activated carbon bag in the placement mechanism 11, and turns on the air pump 121. The air pump 121 compresses the gas into the air cushion tube 122. The rubber air cushion tube 122 expands to seal the distribution cabinet door tightly, thereby strengthening the sealing effect. When the internal gas needs to be replaced, the staff turns on the exhaust fan 7 again, and the air is extracted from the air in the cabinet 1. At the same time, the new external air enters the cabinet 1 through the isolation net 8. The activated carbon in the placement frame 9 can filter out impurities and absorb water vapor. At the same time, the activated carbon bag in the internal placement mechanism 11 can also absorb water vapor in the cabinet 1 to keep it dry. The device has a simple structure and can play a moisture-proof role.

[0024] like Figure 5 As shown, a protective retaining ring 10 is also included. The protective retaining ring 10 is arranged in the wire inlet hole at the front side of the bottom of the cabinet 1, and the protective retaining ring 10 is arranged in the wire outlet hole in the middle of the right side wall of the cabinet 1. The protective retaining ring 10 is made of rubber material, which can protect the wire inlet hole and the wire outlet hole to prevent the entry of impurities and moisture.
