This design can improve the stability of the rack 1 and facilitate the dustproof cabinet 100 to be divided into multiple layers of space to store multiple groups of different electrical components.

[0039] Specifically, the heat dissipation holes 11 are arranged on the top plate 13, the wire inlet 12 is arranged on the bottom plate 14, each door body 2 is hinged to a fixing rod 15, and each sealing strip is fixed to two adjacent fixing rods 15 and the corresponding edge areas of the top plate 13 and the bottom plate 14.

[0040] In order to further improve the stability of the frame 1 , a reinforcing rod may be provided between two adjacent fixing rods 15 .

[0041] In this embodiment, the door body 2 is hinged to the opening side through a plurality of hinges 21 spaced apart from each other, specifically, the door body 2 is hinged to the opening side through three hinges 21 spaced apart from each other. This design can stably hinge the door body 2 to the opening side of the frame 1. According to actual needs, a lock can also be designed between the door body 2 and the frame 1 to facilitate locking of the door body 2.

[0042] In this embodiment, the elastic shrinkable component is any one of elastic rubber, elastic plastic and sponge. Of course, according to actual needs, the elastic shrinkable component can also be designed as other shrinkable components.

[0043] In this embodiment, universal wheels 4 are respectively fixed to the four corner areas at the bottom of the frame 1, and specifically, the universal wheels 4 are fixed to the bottom plate 14 of the frame 1. This design can facilitate the transportation of the dustproof cabinet 100.

[0044] In this embodiment, the dustproof cabinet 100 further includes a refrigerator 3 fixed to one side of the rack 1 and located in the rack 1, specifically, the refrigerator 3 is fixed to the door 2 on one side of the rack 1. This design can release cold air into the dustproof cabinet 100 through the refrigerator 3 to improve the heat dissipation effect of the dustproof cabinet 100.

[0045] In this embodiment, a side of the rack 1 corresponding to the refrigerator 3 is provided with an air inlet 22 therethrough, and the air inlet 22 is aligned with the air inlet of the refrigerator 3, and specifically, the air inlet 22 is provided on the door body 2 on one side of the rack 1. This design facilitates air to enter the refrigerator 3.

[0046] Compared with the prior art, the dustproof cabinet 100 in this embodiment is designed with a sealing strip on the open side of the frame 1, and the door body 2 is designed on the open side of the frame 1, so that when the door body 2 is covered on the frame 1, it will be pressed against the sealing strip to improve the sealing performance between the door body 2 and the frame 1, and prevent dust from entering the dustproof cabinet 100. In addition, an elastic shrinkage piece is designed at the line inlet 12 for the line to pass through, and after the line passes through, the line is wrapped by the shrinkage performance of the elastic shrinkage piece to avoid dust from entering the dustproof cabinet 100 through the line inlet gap of the elastic shrinkage piece, thereby improving its sealing effect. At the same time, such a design does not need to design an external connection jack, and the line is directly inserted into the dustproof cabinet 100 and directly connected to the electrical components in the dustproof cabinet 100, so as to avoid the connection jack being designed outside the dustproof cabinet 100 and being contaminated by dust, resulting in unstable connection.
