[0051] According to some embodiments of the present application, as shown in Figure 4 The first bracket 21 is formed with a first opening 30, the second bracket 22 is formed with a second opening 31, the first opening 30 and the second opening 31 are opposite along the first direction A, and the explosion venting plate 10 is opposite to the first opening 30.

[0052] The first opening 30 penetrates the third side wall 26 along the first direction A, the second opening 31 penetrates the bottom wall 25 along the first direction A, the first opening 30 and the second opening 31 are opposite along the first direction A, and the cross-sectional area of the second opening 31 is greater than that of the first opening 30, that is, the projection of the first opening 30 along the first direction A is located within the projection area of the second opening 31. The explosion venting plate 10 is arranged on the side surface of the third side wall 26 away from the second bracket 22 along the first direction A, and the explosion venting plate 10 covers the first opening 30. The first opening 30 and the second opening 31 facilitate the pressure relief function of the explosion venting plate 10. Optionally, the first opening 30 and the second opening 31 have the same area.

[0053] Therefore, by arranging the first opening 30 and the second opening 31 opposite along the first direction A and the explosion venting plate 10 opposite to the first opening 30, the explosion venting plate 10 can be smoothly vented. At the same time, due to the design of the first opening 30 and the second opening 31, the weight of the first bracket 21 and the second bracket 22 can be reduced, and the cost of the mounting bracket 20 can be reduced.

[0054] According to some embodiments of the present application, as shown in Figure 1 At least one first drainage hole 32 is formed on the first side wall 23, and the first drainage hole 32 is in communication with the groove 27.

[0055] In this embodiment, a plurality of first drainage holes 32 are arranged on at least one side of the first side wall 23 along the second direction B, and the plurality of first drainage holes 32 respectively penetrate the first side wall 23 along the second direction B. The first drainage hole 32 is adapted to communicate the groove 27 with the outside, and the cross-sectional shape of the first drainage hole 32 includes but is not limited to a circular shape. The shape and number of the first drainage hole 32 can be specifically set according to actual needs.

[0056] Therefore, by forming at least one first drainage hole 32 on the first side wall 23, and the first drainage hole 32 is in communication with the groove 27, the groove 27 can be communicated with the outside, so that the liquid in the groove 27 flows to the outside of the mounting bracket 20 through the first drainage hole 32, effectively draining the water in the groove 27, avoiding the water accumulated on the mounting bracket 20 for a long time and penetrating from the edge of the mounting bracket 20 to the inside of the cabinet 100, prolonging the service life of the cabinet 100, and improving the reliability of the mounting bracket 20.

[0057] According to some embodiments of the present application, as shown in Figure 3 The distance between the side surface of the third side wall 26 away from the second side wall 24 and the bottom wall 25 along the first direction A is greater than or equal to the distance between the end of the first side wall 23 away from the bottom wall 25 and the bottom wall 25.

[0058] Optionally, the distance between the side surface of the third side wall 26 away from the second side wall 24 and the bottom wall 25 along the first direction A is H1, and the distance between the end of the first side wall 23 away from the bottom wall 25 and the bottom wall 25 is H2, H1 and H2 satisfy H1≥H2. If the side surface of the third side wall 26 away from the second side wall 24 is on the side surface of the first side wall 23 away from the bottom wall 25, the height of the groove 27 is higher than the height where the explosion venting plate 10 is located.

In this embodiment, the sealing member can be a waterproof sealant. In this way, by arranging the sealing member in the groove 27 and at the connection between the first bracket 21 and the second bracket 22, it can be avoided that the accumulated water in the groove 27 enters the second opening 31 and the inside of the cabinet 100 through the connection between the first bracket 21 and the second bracket 22, the waterproof performance of the mounting bracket 20 to the cabinet 100 is improved, and the waterproof performance and the sealing performance of the mounting bracket 20 are improved, thereby improving the reliability of the mounting bracket 20 and the waterproof performance of the mounting bracket 20 to the cabinet 100.

[0063] The cabinet body 40 is formed with a mounting hole penetrating through the top of the cabinet body 40 along the height direction of the cabinet 100, and the mounting bracket 20 and the explosion vent 10 are mounted at the mounting hole; the second drainage hole 41 penetrates through the side wall of the cabinet body 40, and the two ends of the connecting pipe 42 are connected with the first drainage hole 32 and the second drainage hole 41 respectively, and the accumulated water in the groove 27 flows to the outside of the cabinet 100 through the first drainage hole 32, the connecting pipe 42 and the second drainage hole 41 in sequence.

[0064] Optionally, the top of the cabinet 100 is formed with a plurality of mounting holes and a plurality of second drainage holes 41, and the plurality of mounting holes and the plurality of second drainage holes 41 are arranged at intervals along the length direction of the cabinet 100, and the number of the first drainage holes 32 corresponds to the number of the second drainage holes 41 on the cabinet body 40.

[0065] Therefore, by arranging the mounting bracket 20 at the mounting hole, and arranging the connecting pipe 42 between the second drainage hole 41 and the first drainage hole 32 of the mounting bracket 20, a flow path can be provided for the accumulated water in the groove 27, so that the accumulated water in the groove 27 can be discharged in time, and the accumulated water is prevented from penetrating into the box body 100 from the connection between the first bracket 21 and the second bracket 22 to cause rust in the box body 100, so that the sealing performance of the mounting bracket 20 on the box body 100 is effectively improved, and the service life of the box body 100 is prolonged; at the same time, since the first bracket 21 is designed in a sinking mode, the height of the mounting bracket 20 can be reduced, so that the whole explosion venting plate 10 is arranged in the box body 100, and the risk of overheight after installation of the explosion venting plate 10 is avoided.
