[0025] Embodiment

[0026] In the Chinese patent with the authorization announcement number CN211181440U, during actual use, the warning sign vibrates during the carrying process. At this time, since there is no locking and limiting part between the first warning board and the second warning board, when they vibrate, they will separate, which will cause obstacles to the carrier and reduce its portability.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution: a warning sign for power maintenance, including a first warning sign 1 that can be used for power maintenance. A second warning sign 2 is slidably connected to the surface of the first warning sign 1. A retracting and deploying component 3 is arranged on the surface of the second warning sign ②. The retracting and deploying component 3 is connected to the first warning sign 1. A driving structure 4 is arranged on the surface of the retracting and deploying component 3. The driving structure 4 is connected to the first warning sign 1. A linkage mechanism 5 is arranged on the surface of the driving structure 4. The linkage mechanism 5 is connected to the first warning sign 1. A supporting component 6 is arranged on the surface of the linkage mechanism 5. The supporting component 6 is connected to the first warning sign 1. In order to increase the portability of the device and ensure the stability during storage, a retracting and deploying component 3 is provided. The retracting and deploying component 3 includes a sliding plate 301, a handle 302, a screw rod 303, and a knob 304. The sliding plate 301 is fixed to the surface of the second warning sign 2. The handle 302 is fixed to the surface of the sliding plate 301. The screw rod 303 is installed through the inside of the sliding plate 301. The screw rod 303 is connected to the first warning sign 1 by a bearing. The end of the screw rod 303 penetrates into the inside of the first warning sign 1. The knob 304 is fixed to the end of the screw rod 303. The sliding plate 301 is in threaded connection with the screw rod 303. The sliding plate 301 is slidably fitted to the top surface of the first warning sign 1.

[0028] In order to enable the retracting and deploying operations and the supporting operation to be carried out simultaneously and reduce the time required for installation, a driving structure 4 is provided. The driving structure 4 includes a first bevel gear 401, a second bevel gear 402 and a screw rod 403. The first bevel gear 401 is fixed on the surface of the screw rod 303. The surface of the first bevel gear 401 is meshed and connected with the second bevel gear 402. In order to prevent the rotation speed of the support frame 602 from being too fast, the diameter of the first bevel gear 401 is smaller than that of the second bevel gear 402, and the thread density of the screw rod 303 is smaller than that of the screw rod 403. The screw rod 403 is fixed at the center of the bottom of the second bevel gear 402. The screw rod 403 is connected to the first warning sign 1 by a bearing. In order to provide a power source for the supporting operation, a linkage mechanism 5 is provided. The linkage mechanism 5 includes a slider 501 and a rack 502. The slider 501 is sleeved on the surface of the screw rod 403. The rack 502 is fixed on the surface of the slider 501. The slider 501 is threadedly connected to the screw rod 403. The slider 501 is slidably fitted to the side wall of the first warning sign 1. In order to increase the stability of the device during installation, a support component 6 is provided. The support component 6 includes a spur gear 601 and a support frame 602. The surface of the rack 502 is meshed and connected with the spur gear 601. The spur gear 601 is fixed on the side of the support frame 602. The support frame 602 is connected to the first warning sign 1 by a bearing.

[0029] Working principle or structural principle. During daily use, the staff can carry the device by using the handle 302. When it is carried to the maintenance site, the staff can use the knob 304 to drive the screw rod 303 to rotate. During the rotation of the screw rod 303, the threads on the surface will drive the slide plate 301 to move, thereby driving the second warning sign 2 to extend and open. When the screw rod 303 rotates, it will also drive the screw rod 403 to rotate through the first bevel gear 401 and the second bevel gear 402. Since the screw rod 403 is threadedly connected to the slider 501, when the screw rod 403 rotates, it will drive the slider 501 to displace, and then the rack 502 will drive the spur gear 601 to rotate, and finally the support frame 602 will rotate and open. The staff can make the support frame 6 to fit the ground, and make the first warning sign 1 and the second warning sign 2 form a certain angle with the ground.

[0030] In summary, the device has the advantages of good stability and being easy to carry.
