Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinet maintenance, and more specifically, particularly relates to a lighting device for power distribution cabinet maintenance. Background Art

[0002] A power distribution cabinet is a cabinet that integrates electrical components for power distribution. Its main function is to distribute power to and control electrical equipment. During operation, the power distribution cabinet often needs to be repaired due to circuit failures. In order to ensure sufficient light during maintenance, staff often hold flashlights or wear headlamps to illuminate the interior of the power distribution cabinet.

[0003] The existing application number is: CN202223331624.0. The utility model discloses a novel low-voltage distribution cabinet including a distribution cabinet body and a lighting device. The distribution cabinet body cooperates with the lighting device, and the lighting device is turned on by a touch device, so that the maintenance staff can immediately perform maintenance after opening the door. The lighting range on the top and both sides covers the overall maintenance angle; in emergency situations, the ceiling light device can also be taken out and used separately, which greatly saves maintenance time. If the maintenance takes a long time, the ceiling light device can also play a basic lighting role without being taken out separately, avoiding the damage to the cervical spine caused by the long-term fixed posture of the helmet-type lighting lamp, and improving efficiency, eliminating the cumbersome and inconvenient hand-held lighting equipment.

[0058] A contact member 601, the contact member 601 is fixedly connected to the front end of the transmission rack 6;

[0059] A fixed slide rail 602, which is fixedly connected to the rear end of the transmission rack 6;

[0060] The clamping lighting component is arranged inside the connecting piece 2 .

[0061] The clamping lighting assembly includes:

[0062] A transmission slider 3, the transmission slider 3 is slidably connected inside the connecting member 2;

[0063] A clamping plate 4, the clamping plate 4 is fixedly connected to the rear of the transmission slider 3;

[0064] A transmission screw 5, which is rotatably connected to the inside of the connecting member 2, and is threadedly connected to the transmission slider 3;

[0065] Knob 501 is coaxially fixedly connected to the right end of the transmission screw 5. The function of the knob 501 is to rotate the threaded transmission mechanism formed by the transmission screw 5 and the transmission slider 3 to drive the clamping plate 4 to move to the left, so that the connecting piece 2 and the clamping plate 4 clamp the right wall of the distribution cabinet body 1, so that the connecting piece 2 and the distribution cabinet body 1 are fixed.

[0066] The clamping lighting assembly also includes:

[0067] A connecting slide block 8, wherein the connecting slide block 8 is slidably connected inside the fixed slide rail 602;

[0068] The lighting lamp 801 is fixedly connected to the rear of the connecting slide block 8. The function brought about is that, through the connecting slide block 8, the lighting lamp 801 can slide left and right in the fixed slide rail 602, so as to illuminate the place that needs maintenance.

[0069] The clamping lighting assembly also includes:

[0070] A connecting shaft 9, the connecting shaft 9 is rotatably connected inside the connecting member 2;

[0071] The transmission gear 901 is coaxially fixedly connected to the outside of the connecting shaft 9, and the transmission gear 901 is meshed with the transmission rack 6, which has the effect of pushing the contact piece 601 backward, and the gear rack transmission mechanism formed by the meshing of the transmission gear 901 and the transmission rack 6 drives the connecting shaft 9 to rotate.

[0072] The clamping lighting assembly also includes:

[0073] A transmission ratchet 902, which is coaxially fixedly connected to the outside of the connecting shaft 9;

[0074] A transmission pawl 10, the transmission pawl 10 is rotatably connected inside the connecting member 2, and the transmission pawl 10 is meshed with the transmission ratchet 902;

Under the action of the resistance spring 603, the transmission rack 6 is brought back to the starting position, and the end of the transmission pawl 10 is released. Under the action of the return spring 1001, the transmission pawl 10 is engaged with the transmission ratchet 902 again.

[0078] The specific usage and function of this embodiment are as follows:

[0079] When the distribution cabinet body 1 needs to be inspected, first open the cabinet door 101 to determine the specific inspection position, then make the left side of the connector 2 contact with the right wall corresponding to the inspection position of the distribution cabinet body 1, then rotate the knob 501, and the threaded transmission mechanism composed of the transmission screw 5 and the transmission slider 3 drives the clamping plate 4 to move to the left, so that the connector 2 and the clamping plate 4 clamp the right wall of the distribution cabinet body 1, so that the connector 2 and the distribution cabinet body 1 are fixed, and the lighting lamp 801 can slide left and right in the fixed slide rail 602 through the connecting slider 8, so as to illuminate the place that needs maintenance; when it is felt that the lighting lamp 801 is far away from the equipment in the distribution cabinet body 1 and the illumination is not clear enough, push the contact member 601 backward to drive the fixed slide rail 602 to move backward, so as to facilitate the illumination and observation of the equipment in the distribution cabinet body 1 at a close distance. In the process of pushing the contact member 601 backward, the transmission The gear-rack transmission mechanism formed by the meshing of the movable gear 901 and the transmission rack 6 drives the connecting shaft 9 to rotate. Under the action of the ratchet-pawl transmission mechanism formed by the meshing of the transmission pawl 10 and the transmission ratchet 902, the transmission rack 6 can only move backward. At the same time, the resistance spring 603 can provide a certain resistance, so that the staff can more accurately control the movement range of the transmission rack 6. After the observation is clear, pressing the end of the transmission pawl 10 downward can disengage the transmission pawl 10 from the transmission ratchet 902. Under the action of the resistance spring 603, the transmission rack 6 and the lighting lamp 801 are brought back to the starting position, so that the lighting lamp 801 is away from the equipment in the distribution cabinet body 1, giving the staff more room for movement of their hands, making it convenient for the staff to perform maintenance and other operations, and loosening the end of the transmission pawl 10. Under the action of the reset spring 1001, the transmission pawl 10 is meshed with the transmission ratchet 902 again, which is convenient for reuse.
