DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: an air duct structure of a medical cabinet, comprising a first air duct plate 4, a second mounting plate 10, a limit card hole 11, a limit card block 12, a reset spring 13 and a fan 14, an air duct cover plate 1 is fitted on the upper end surface of the first air duct plate 4, a mounting wall 3 is fixed on the upper end surface of the first air duct plate 4, a second air duct plate 6 is connected to the tail end of the first air duct plate 4, mounting studs 5 are fixed on the sides of the first air duct plate 4 and the second air duct plate 6, and a fastening screw 2 is rotatably connected inside the mounting studs 5;

[0021] A limit card hole 11 is provided inside the mounting wall 3, and a first mounting plate 8 is fittedly connected to the mounting wall 3. Sealing plates 7 are fixed to both front and rear end surfaces of the first mounting plate 8. An air suction port 9 is provided on the side of the first mounting plate 8. A second mounting plate 10 is fittedly installed on the inner wall of the first mounting plate 8. A fan 14 is fixed on the side of the second mounting plate 10. A limit card block 12 is movably connected inside the first mounting plate 8, and a return spring 13 is fixed between the limit card block 12 and the first mounting plate 8. In this design, the fan adopts a method of connecting the limit card block 12 with the limit card hole 11, and it does not need to use tools to disassemble the fan, which is convenient for loading and unloading and cleaning, thereby facilitating the staff to clean the air duct of the medical cabinet, preventing impurities from blocking the air duct opening, and improving the refrigeration effect of the medical cabinet.

[0022] As the first embodiment of the utility model: the lower end surface of the air duct cover plate 1 can be fitted and sealed with the side surfaces of the first air duct plate 4 and the second air duct plate 6, the inner diameter of the mounting stud 5 is equal to the outer diameter of the fastening screw 2, and the two can be fitted and rotatably connected, the mounting stud 5 and the fastening screw 2 form a mounting assembly, and the mounting assembly is provided with multiple groups. The design fixes the air duct cover plate 1 by fitting and rotating the fastening screw 2 and the mounting stud 5, so that the air duct cover plate 1 seals the first air duct plate 4 and the second air duct plate 6, so that the cooled air is transported from the second air duct plate 6 to the first air duct plate 4 and then blown out, and the internal gas of the medical cabinet is circulated;

[0023] Two groups of sealing plates 7 are provided, and the two groups of sealing plates 7 are equal in size and are symmetrically fixed on the front and rear end surfaces of the first mounting plate 8. The two groups of sealing plates 7 can be fitted and connected with the side of the mounting wall 3. The limiting block 12 is set as a trapezoidal body mechanism. The specifications of the limiting block 12 match the specifications of the limiting hole 11, and the two can be fitted and connected. A movable hole is opened inside the first mounting plate 8.
