Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 and Figure 2 An embodiment provided by the present utility model: a control cabinet for an electric brake release of a machine-roomless elevator, including a control cabinet body 1.

A connecting shaft 5 is fixedly connected inside the L-shaped arm 4. A pulley 6 is rotatably connected to the outer wall of the connecting shaft 5. The outer wall of the pulley 6 is slidably connected to a fixed block 7. The outer wall of the fixed block 7 is fixedly connected to a wall 8. A first spring 9 is fixedly connected to the outer wall of the L-shaped arm 4. An electric brake release body 10 is fixedly connected inside the control cabinet body 1. A rotating assembly is provided on the outer wall of the control cabinet body 1, and the rotating assembly is used to open and close the control cabinet body 1.

[0025] Specifically, first move the control cabinet body 1. The control cabinet body 1 drives the fixed shaft 3 to move through the U-shaped shell 2. The fixed shaft 3 drives the L-shaped arm 4 to move. The L-shaped arm 4 drives the pulley 6 to rotate on the fixed block 7 through the connecting shaft 5. Blocked by the fixed block 7, the L-shaped arm 4 will rotate around the fixed shaft 3 and at the same time squeeze the first spring 9. Under the elastic force of the first spring 9, the pulley 6 in the L-shaped arm 4 can be stuck on the fixed block 7, achieving the effect of docking the control cabinet body 1 on the wall 8.

[0026] Refer to Figure 1, the rotating assembly includes a hinge 11, the outer wall of the hinge 11 is fixedly connected to the outer wall of the control cabinet body 1, the outer wall of the hinge 11 is fixedly connected with a cabinet door 12, and the outer wall of the cabinet door 12 is fixedly connected with a handle 13.

[0027] Specifically, by pulling the handle 13, the cabinet door 12 can be opened or closed under the connection of the hinge 11, and the hinge 11 plays a role in connecting the cabinet door 12 and the control cabinet body 1.

[0028] Refer to Figure 1 , Figure 3 and Figure 4 , a fixing plate 14 is fixedly connected inside the control cabinet body 1, a first fixing shell 15 is fixedly connected to the outer wall of the fixing plate 14, and a fixing column 16 is fixedly connected inside the first fixing shell 15; a first clamping rod 17 is rotatably connected to the outer wall of the fixing column 16, a second spring 18 is fixedly connected to the outer wall of the first clamping rod 17, and the outer wall of the second spring 18 is slidably connected inside the first fixing shell 15; a connecting rod 19 is fixedly connected to the outer wall of the first clamping rod 17, and the outer wall of the connecting rod 19 is slidably connected inside the first fixing shell 15; a second clamping rod 20 is slidably connected to the outer wall of the first clamping rod 17, a second fixing shell 21 is fixedly connected to the outer wall of the second clamping rod 20, and the outer wall of the second fixing shell 21 is slidably connected to the outer wall of the fixing plate 14; the outer wall of the second fixing shell 21 is fitted with the outer wall of the first fixing shell 15, and a heat dissipation base 22 is fixedly connected to the outer wall of the fixing plate 14; a heat dissipation fan 23 is fixedly connected to the outer wall of the heat dissipation base 22, and a heat dissipation fin 24 is fixedly connected to the outer wall of the heat dissipation fan 23.

[0029] Specifically, by lifting the connecting rod 19, the first clamping rod 17 is driven to rotate on the fixing column 16, and at the same time, the second spring 18 is compressed, and then the first clamping rod 17 and the second clamping rod 20 can be separated from each other, so that the first fixing shell 15 and the second fixing shell 21 can be docked or separated from each other. Under the combined action of the heat dissipation base 22, the heat dissipation fan 23 and the heat dissipation fins 24, the effect of dissipating heat and cooling the electric brake body 10 is achieved.

[0030] Working principle: When the control cabinet needs to be used, first move the control cabinet body 1. The control cabinet body 1 drives the fixed shaft 3 to move through the U-shaped shell 2, drives the L-shaped arm 4 to move through the fixed shaft 3, and the L-shaped arm 4 drives the pulley 6 to rotate on the fixed block 7 through the connecting shaft 5. Blocked by the fixed block 7, the L-shaped arm 4 will rotate around the fixed shaft 3 and squeeze the first spring 9 at the same time. Thus, the pulley 6 in the L-shaped arm 4 can be stuck on the fixed block 7, and then the control cabinet body 1 can be docked on the wall 8. By pulling the handle 13, the cabinet door 12 can be opened or closed under the connection of the hinge 11. By lifting the connecting rod 19, the first clamping rod 17 rotates on the fixed column 16 and squeezes the second spring 18 at the same time. Thus, the first clamping rod 17 and the second clamping rod 20 can be separated from each other, and then the first fixed shell 15 and the second fixed shell 21 can be docked or separated from each other. Under the combined action of the heat dissipation base 22, the heat dissipation fan 23 and the heat dissipation fins 24, the electric brake release body 10 can be cooled. This control cabinet not only achieves the effect of quickly docking the control cabinet body 1 to the wall 8, thus greatly shortening the installation time and improving the work efficiency, but also achieves the effect of quickly installing or disassembling the heat dissipation fan 23 as needed. Thus, maintenance personnel can flexibly adjust according to the actual situation without having to perform complex disassembly and assembly work during each maintenance, further improving the maintenance efficiency.
