[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5The utility model provides a technical solution: a distribution box with a dehumidification function, comprising a distribution box shell 1, a sealing cover plate is installed on the front side of the distribution box shell 1 through a hinge, and a partition plate for installing components is arranged inside the distribution box shell 1; rainproof plates 2 are symmetrically arranged on the left and right sides of the outer surface of the distribution box shell 1, and a dustproof plate 3 is installed on the outer surface of the distribution box shell 1, and a mounting column 4 is installed on the inner surface of the distribution box shell 1, and the mounting column 4 is connected to the fastening screw 5, and the fastening screw 5 is arranged through the dehumidification plate 6, a dehumidification component 7 is installed on the dehumidification plate 6, and a positioning component 8 is provided on the inner surface of the distribution box shell 1; square through ventilation grooves are provided on the left and right sides of the distribution box shell 1, and a cylindrical through ventilation groove is provided on the dustproof plate 3 installed outside the distribution box shell 1; the dehumidification component 7 includes a breathable plate 701 and a heating pipe 704, and the breathable plate 701 is connected to the dehumidification plate 6, and a cylindrical through ventilation groove is provided on the breathable plate 701, and a heating pipe 704 is installed on the dehumidification plate 6.

[0023] When it is necessary to dehumidify the interior of the distribution box casing 1 (the distribution box casing 1, the front side of which is provided with a sealing cover plate by a hinge, and a sealing rubber gasket is arranged between the sealing cover plate and the distribution box casing 1), the motor 702 starts to work, because the output end of the motor 702 is connected to the rotating fan blade 703 by a rotating shaft, and the rotating fan blade 703 starts to rotate at this time. With the rotation of the rotating fan blade 703, the dry gas outside the distribution box casing 1 can be introduced into the interior of the distribution box casing 1. When it is necessary to quickly dehumidify the interior of the distribution box casing 1, the heating tube 704 starts to work (a heating resistor is arranged inside the heating tube 704). At this time, the heating tube 704 starts to heat the passing air. The heated air enters the interior of the distribution box casing 1, so that the interior of the distribution box casing 1 can be quickly dehumidified, and the left and right sides of the distribution box casing 1 can be rainproofed by the rainproof plate 2 and the dustproof plate 3 to prevent rainwater from entering the interior of the distribution box casing 1 and causing the interior of the distribution box casing 1 to be wet.

[0024] The fastening screw 5 is connected to the mounting column 4 through a threaded hole opened on the mounting column 4, and there are four mounting columns 4 in total; the positioning assembly 8 includes a fixed bearing 801, a rotating clamping plate 802 and a counterweight block 803, and the fixed bearing 801 is installed on the distribution box housing 1, and the rotating clamping plate 802 is connected to the fixed bearing 801, and the lower end of the counterweight block 803 is connected to the counterweight block 803; the rotating clamping plate 802 is set as a "7" shape structure, and the rotating clamping plate 802 is fitted with the dehumidification plate 6 through a through limiting groove opened on the dehumidification plate 6.

[0025] When it is necessary to disassemble, replace or clean the dehumidifier assembly 7, rotate the fastening screw 5 so that the fastening screw 5 starts to move away from the dehumidifier plate 6 until the fastening screw 5 is no longer connected to the threaded hole opened on the mounting post 4. At this time, the fastening screw 5 can be removed from the mounting post 4, and then the rotating clamping plate 802 is rotated (the rotating clamping plate 802 starts to rotate under the action of the fixed bearing 801) to rotate the rotating clamping plate 802 180° so that the rotating clamping plate 802 starts to be in the same position as the through-limiting groove opened on the dehumidifier plate 6. The dehumidifier plate 6 can be pulled, and the rotating clamping plate 802 starts to slide in the through-limiting groove opened on the dehumidifier plate 6 until the dehumidifier plate 6 is removed (when the dehumidifier plate 6 is removed, the rotating clamping plate 802 starts to rotate under the action of the counterweight block 803, so that the counterweight block 803 is at the lowest position), and then the dehumidifier assembly 7 installed on the dehumidifier plate 6 can be removed. When the dehumidification component 7 is cleaned or repaired, the dehumidification plate 6 is moved in the direction close to the distribution box housing 1. At the same time, the rotating card plate 802 is moved with a finger, and the rotating card plate 802 begins to rotate 180°. When the rotating card plate 802 and the through-limiting groove opened on the dehumidification plate 6 are in the same position, the dehumidification plate 6 is pushed, and the rotating card plate 802 begins to slide in the through-limiting groove opened on the dehumidification plate 6 until the dehumidification plate 6 and the mounting column 4 are fitted together. At this time, the rotating card plate 802 can be loosened, and under the action of the gravity of the counterweight block 803, the rotating card plate 802 begins to rotate 180°, thereby realizing the fitting and limiting of the dehumidification plate 6, and then the fastening screw 5 is passed through the dehumidification plate 6, and then the fastening screw 5 is rotated to connect with the threaded hole opened on the mounting column 4, thereby realizing the installation and fixing of the dehumidification plate 6. Under the action of the rotating card plate 802, the dehumidification component 7 can be pre-fixed, so that when the dehumidification plate 6 is installed, the dehumidification plate 6 can be pre-fixed first, and then when the fastening screw 5 is rotated, it is no longer necessary to manually press the dehumidification plate 6 to fix it, which is more convenient and quick. Under the action of the rotating card plate 802, the dehumidification plate 6 can be pressed into place, and subsequently, only the fastening screw 5 needs to be directly rotated. There is no need to judge whether the fastening screw 5 is not rotated into place or whether it is over-rotated, thereby ensuring that the dehumidification plate 6 and the dehumidification component 7 are smoothly installed and fixed.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
