Detailed Embodiments

[0018] Referring to Figures 1-4 , the present utility model relates to an easily maintainable vehicle control room equipment cabinet, including a cabinet body 1, an end cover 2, a maintenance small door 3, a hook rod 4, a hook 5 and a limiting rod 6. Maintenance small doors 3 are opened on the left and right side walls of the cabinet body 1. End covers 2 for embedding access control devices are symmetrically arranged on the front and rear sides of the cabinet body 1. The bottom of the end cover 2 is hinged to the cabinet body 1, and a hook rod 4 is arranged at the top. A hook 5 is arranged in the cabinet body 1 corresponding to the hook rod 4. The hook 5 is hinged to a hook seat 8 through a hook rotating shaft 7. The hook seat 8 is fixed in the cabinet body 1. The hook 5 is fixedly welded to the hook rotating shaft 7. Unlocking dials 9 are symmetrically welded at both ends of the hook rotating shaft 7. The unlocking dials 9 face the maintenance small door 3. The hook 5 is equipped with a return spring 10. One end of the return spring 10 is fixed on the hook 5, and the other end is fixed on the side wall of the cabinet body 1. There is one return spring 10 on each of the left and right sides.

[0019] The end cover 2 is provided with a positioning bracket 11. Corresponding to the positioning bracket 11, the cabinet body 1 is provided with a position switch 12, a positioning rod 13 and a spring ejector rod 14 in parallel. After the hook is unlocked, the end cover 2 is pushed open by the spring ejector rod 14. When the end cover 2 is closed, the positioning rod 13 is inserted into the corresponding hole of the positioning bracket 11 to prevent the end cover from swinging left and right. At the same time, the positioning bracket 11 contacts the position switch 12, and the system indicates that the end cover has been closed in place.

[0020] In order to ensure the fixed position of the end cover 2 during maintenance, the end cover 2 is equipped with a limiting rod 6. One end of the limiting rod 6 is hinged to the end cover 2, and the other end is connected to a limiting support 16 through a limiting shaft 15. The limiting shaft 15 is fixed on the limiting support 16, and the limiting support 16 is fixed on the side wall of the cabinet body 1. The limiting rod 6 is provided with a sliding groove 6.1 corresponding to the limiting shaft 15. One end of the sliding groove 6.1 close to the limiting support 16 is provided with a limiting card slot 6.2, and the limiting card slot 6.2 communicates with the sliding groove 6.1. When the end cover 2 is fully opened, the limiting shaft 15 slides along the sliding groove 6.1 into the limiting card slot 6.2, thereby realizing the locking of the position of the end cover 2. When the end cover 2 is closed, the limiting rod 6 is lifted upward, the limiting shaft 15 slips out of the limiting card slot 6.2 and enters the sliding groove 6.1, the position of the end cover 2 is unlocked, and the end cover 2 is pressed, and the hook 5 hooks the hook rod 4, and the position of the end cover 2 is locked.

[0021] The hook seat 8, the position switch 12, the positioning rod 13 and the spring ejector rod 14 are all fixed on the mounting bracket 17. The hook seat 8 is fixed below the mounting bracket 17, and the position switch 12, the positioning rod 13 and the spring ejector rod 14 are arranged side by side left and right on the side of the mounting bracket 17.

[0022] Working principle:

[0023] Opening method: Open the maintenance small door 3, dial the unlocking dial 9 downward. The unlocking dial 9 drives the hook rotating shaft 7 to rotate, and the hook 5 fixed on the hook rotating shaft 7 also rotates accordingly. When it rotates to a certain angle, the hook 5 disengages from the hook rod 4 on the end cover 2. Under the action of the spring ejector rod 14, the end cover 2 is pushed open a certain distance to unlock the hook rod 4. At this time, the unlocking dial 9 is released, and the hook 5 returns to its original position under the action of the return spring 10. Since the end cover 2 and the hook rod 4 are pushed out a certain distance by the spring ejector rod 14, the hook 5 does not lock the hook rod 4. Continue to open the end cover 2, the limiting shaft 15 slides along the sliding groove 6.1 of the limiting rod 6 to the limiting card slot 6.2, and the limiting rod 6 is locked, so that the end cover 2 is stably fixed in a certain position, which is convenient for installing and maintaining equipment.

[0024] Closing method: Lift the limit rod 6 upwards, the limit shaft 15 returns to the chute 6.1, unlocking the locking of the limit shaft 15 on the limit rod 6. Close the end cover 2 inwards. When the in-place bracket 11 touches the spring ejector rod 14, press down slightly with a little force. The hook rod 4 slides into the hook 5 through the slope on the hook 5, and the hook 5 locks the hook rod 4. At the same time, the positioning rod 13 is inserted into the hole of the positioning bracket 11 to prevent the end cover 2 from swinging left and right. The in-place bracket 11 presses the in-place switch 12, and the system displays that the end cover has been closed in place.

[0025] In addition to the above embodiments, the present utility model also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
