[0020] Embodiment

[0021] Please refer to Figures 1-4 As shown, the present utility model provides a cabinet door locking mechanism for a switch cabinet, including a cabinet body 1. A cabinet door 2 is provided at the front end of the cabinet body 1. Heat dissipation slots 4 are arranged at equal intervals at a position close to the bottom on one side inside the cabinet body 1. A housing 6 is provided at the middle position of the front end on one side inside the cabinet body 1. Connecting seats 12 are provided at both ends inside the housing 6. Locking plugs 11 penetrate through both ends of the housing 6. A return spring 13 is arranged between the connecting seats 12. A locking slot 5 is provided at the middle position of the inner side of the cabinet door 2. The locking slot 5 is nested outside the housing 6. Locking through holes 7 are provided at both ends inside the locking slot 5. One end of the locking plug 11 is fixedly connected to one end of the connecting seat 12. The other end of the locking plug 11 penetrates through the inside of the locking through hole 7. A reserved slot 8 is provided between one side of the housing 6 and the front end on one side inside the cabinet body 1. A lever 3 is provided on one side of the connecting seat 12. One side of the lever 3 penetrates through the inside of the reserved slot 8. The diameter of the lever 3 is smaller than the inner width of the reserved slot 8. The lever 3 can move up and down in the reserved slot 8. By the return spring force of the return spring 13, the locking plug 11 is pushed to penetrate through the locking through hole 7 to lock and close the cabinet door 2. By moving the lever 3 in opposite directions, the connecting seat 12 is driven to compress the return spring 13, so that the locking plug 11 is withdrawn from the locking through hole 7 and retracted into the inside of the housing 6, thereby opening the cabinet door 2, thus achieving the effect of more convenient, faster and stable locking and opening of the switch cabinet, and the operability is stronger;

[0022] When in use, move the lever 3 towards each other, which will drive the connecting seat 12 to compress the return spring 13, thus retracting the locking plug 11 into the interior of the housing 6. Then close the cabinet door 2, nest the locking groove 5 outside the housing 6, align the locking through hole 7 with the locking plug 11, and then release the lever 3. The return spring 13 will push the locking plug 11 through the locking through hole 7 to lock and close the cabinet door 2. When the cabinet door 2 needs to be opened again, move the lever 3 towards each other to withdraw the locking plug 11 from the locking through hole 7, and the cabinet door 2 will be opened;

[0023] As a further implementation of this embodiment, as Figures 1-4 shown, a limiting component is provided between the exteriors of the levers 3. The limiting component includes a connecting sleeve 9, which is sleeved on the outside of the lever 3. A limiting strut 10 is provided between the exteriors of the connecting sleeve 9. Sleeve the connecting sleeve 9 on the outside of the lever 3, and limit the spacing of the lever 3 through the limiting strut 10, which can prevent the lever 3 from moving uncontrollably towards or away from each other under the influence of the opening or closing state of the cabinet door 2, affecting the stability of the locking mechanism. And when the cabinet door 2 needs to be closed or opened, the connecting sleeve 9 can be removed to operate the locking mechanism;

[0024] Specific working principle:

[0025] When using the locking mechanism, first move the lever 3 towards each other, which will drive the connecting seat 12 to compress the return spring 13, thus retracting the locking plug 11 into the interior of the housing 6. Then close the cabinet door 2, nest the locking groove 5 outside the housing 6, align the locking through hole 7 with the locking plug 11, and then release the lever 3. The return spring 13 will push the locking plug 11 through the locking through hole 7 to lock and close the cabinet door 2. After closing the cabinet door 2, sleeve the connecting sleeve 9 on the outside of the lever 3, and limit the spacing of the lever 3 through the limiting strut 10, so as to prevent the lever 3 from moving uncontrollably towards or away from each other under the closed state of the cabinet door 2, affecting the locking stability. When the cabinet door 2 needs to be opened, remove the connecting sleeve 9 and move the lever 3 towards each other again to withdraw the locking plug 11 from the locking through hole 7, and the cabinet door 2 will be opened.
