In this way, the cabinet 110 is effectively radiated and cooled, which is beneficial to ensure the cabinet 110 Internal components work normally. In the heat dissipation mechanism of the switch cabinet, the heat dissipation box 130 is installed on the cabinet body 110, so that the heat is uniformly discharged from the heat dissipation box 130, so as to avoid the need to open the cabinet door 116 or the top cover of the cabinet body 110 and cause the internal components to be directly exposed.

Further, please refer to FIG. 6 , the buffer assembly 113 includes a telescopic rod 1131 and a spring 1132 , the rain shield 111 is installed on the cabinet body 110 through the telescopic rod 1131 , the spring 1132 is sleeved on the telescopic rod 1131 , and one end of the spring 1132 is The other end of the spring 1132 abuts against the cabinet body 110 . In this way, the position of the rain shield 111 on the cabinet body 110 can be adjusted through the telescopic rod 1131 . At the same time, through the spring 1132, the rain shield 111 is effectively damped and buffered.

In one embodiment, the cabinet body 110 is provided with multiple layers of drawers 118 at intervals, and the drawers 118 are designed to facilitate the placement of components. Meanwhile, the cabinet body 110 is also provided with an openable cabinet door 116 , the cabinet door 116 is provided with a cabinet lock 115 , and the cabinet body 110 is provided with a lock slot 117 matched with the cabinet lock 115 . In addition, the switch cabinet 100 further includes a base 114 on which the cabinet body 110 is installed.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

The above-mentioned embodiments only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
