[0018] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0019] As shown in Figure 1 The cabinet body 1 is hingedly provided with a pair of cabinet doors 2, and fan seats 3 are arranged on both sides of the cabinet body 1, and the fan seats 3 are provided with fans, which can draw out or send in the gas in the cabinet body 1, so as to accelerate the air flow, and the heat generated by the heating elements in the cabinet body 1 can be carried away by the air, so as to achieve the purpose of cooling and heat dissipation.

[0020] A dust cover 4 is arranged on the fan seat 3, and a dustproof frame 5 is connected in the dust cover 4, and a filter screen 51 is arranged on the dustproof frame 5, which can protect the fan seat 3 and filter the external air entering the cabinet body 1 to prevent dust from entering. The dustproof frame 5 can be detached from the dust cover 4, so that the filter screen 51 can be thoroughly cleaned and the whole can be replaced.

[0021] Please refer to Figures 2 to 4 , the L-shaped clamping groove 31 is arranged on the side of the fan seat 3, and the clamping groove 31 is composed of a clamping groove 32 and a limiting groove 33 connected end to end; the clamping pin 41 in the dust cover 4 is clamped into the gap of the clamping groove 32 and gradually slides into the limiting groove 33 along the contour of the clamping groove 32. A counterweight 6 is arranged on the side of the dust cover 4, and due to the gravity of the counterweight 6, the dust cover 4 is in the most stable state only when the counterweight 6 is at the lowest end of the dust cover 4; in other cases, the dust cover 4 will be deflected under the influence of the gravity of the counterweight 6. When the counterweight 6 is at the lowest end, the clamping pin 41 and one end of the clamping groove 31 are clamped with each other, and this clamping state needs external force to change due to the existence of the counterweight 6, so the clamping state is stable in normal use, which ensures the stable use of the dust cover 4.

[0022] The clamping groove 32 is parallel to the axial direction of the fan seat 3, and this vertical clamping method is more convenient for taking and placing the clamping pin 41; the limiting groove 33 is arranged inclinedly along the peripheral surface of the fan seat 3, and the included angle between the limiting groove 33 and the clamping groove 32 is 95°-105°, and this obtuse angle setting makes the dust cover 4 gradually close to the fan seat 3 when the clamping pin 41 moves in the limiting groove 33, so that the dustproof frame 5 is closer to the fan seat 3.

[0023] The connecting part of the clamping groove 32 and the limiting groove 33 is connected through a rounded corner structure, facilitating the smooth sliding of the clamping pin 41 along the clamping groove 31; and the widths of the clamping groove 32 and the limiting groove 33 are the same, ensuring the normal clamping of the clamping pin 41; the length of the limiting groove 33 is 1.5-1.8 times the length of the clamping groove 32, and the length of the limiting groove 33 is greater than the length of the clamping groove 32, having a longer limiting length; the setting angle of the limiting groove 33 on the circumferential surface of the fan base 3 is 7°-12°, and the limiting groove 33 of this size can facilitate the simultaneous setting of multiple groups on the circumferential surface of the fan base 3, which cooperate with each other to ensure the clamping state with the clamping pin 41 and ensure the stability of the use of the dust cover 4.

[0024] The fan base 3 is internally provided with a ventilation fan, and protective nets 34 are arranged on both sides of the fan base 3, the purpose of the protective nets 34 is mainly to protect the ventilation fan in the fan base 3, avoiding bumping the internal ventilation fan during operation, affecting its normal use.

[0025] The counterweight 6 is connected with the mounting seat 42 on the side of the dust cover 4 through the connecting head 61 at the end, and different weights of the counterweight 6 can be replaced according to the use requirements, ensuring the use effect.
