[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-4 As shown, a maintenance warning device for power maintenance and operation includes multiple support legs 1, which are arranged in pairs. Two support legs 1 in the same group are hinged at one end by a pin. One side of one of the support legs 1 in any group is provided with a sliding groove 9. The sliding grooves 9 on the two adjacent groups of support legs 1 are arranged opposite to each other. A slide block 11 is slidably connected in the sliding groove 9. A connecting plate 5 is provided between the two opposite sliding grooves 9. One end of the connecting plate 5 is hinged to the top of one slide block 11 and the other end is hinged to the bottom of the other slide block 11. A threaded pin 13 is threadedly connected to the bottom of the sliding groove 9. A push block 12 is rotatably connected to one end of the threaded pin 13. The push block 12 is slidably installed with the sliding groove 9. There are four support legs 1 in two groups. The two opposite sliding grooves 9 are used to install maintenance warning signs.

[0025] In this technical solution, support legs 1 are set up and placed on the ground to serve as a frame for installing maintenance warning signs. Slide grooves 9 are set up and the maintenance warning signs are placed between two slide grooves 9. The side walls of the slide grooves 9 limit the front and back of the maintenance warning signs. Slide bases 11 are set up and after the maintenance warning signs are placed between the two slide grooves 9, their tops contact and limit the movement with the slide bases 11. Connecting plates 5 connect the two sets of support legs 1 together and also protect the top of the maintenance warning signs to prevent objects from falling and damaging them. Push blocks 12 are set up and moved by turning the threaded pins 13, so that the push blocks 12 abut against the bottom of the maintenance warning signs, thereby fixing the maintenance warning signs on the device.

[0026] In addition, when the device is stored, the sliding of the sliding seat 11 drives the inclination of the connecting plate 5, and the distance between the two groups of supporting legs 1 is increased, until one sliding seat 11 moves to the bottom of the sliding groove 9 and the other sliding seat 11 moves to the top of the sliding groove 9, the connecting plate 5 is accommodated in the sliding groove 9, and the two groups of supporting legs 1 are close to each other, which is convenient for storage.

[0027] As shown in Figure 6 , the opposite sides of the two supporting legs 1 in the same group are concave to form a concave surface 14, and the concave surface 14 extends outward at one end to form a protrusion 10, and the two protrusions 10 in the same group of supporting legs 1 are arranged away from each other.

[0028] In the technical solution, by arranging the concave surface 14 and the protrusion 10, when the two supporting legs 1 rotate and coincide, the protrusion 10 moves into the concave surface 14.

[0029] As shown in Figure 6 , the supporting leg 1 is threadedly connected with a lead screw 2 through the protrusion 10, one end of the lead screw 2 is fixedly connected with a connecting rod 7, the connecting rod 7 is fixedly connected with a universal joint 8 through the concave surface 14, and the two connecting rods 7 in the same group of supporting legs 1 are fixedly connected with the two ends of one universal joint 8.

[0030] In the technical solution, by arranging the lead screw 2, the lead screw 2 is twisted to drive the connecting rod 7 to move, and then drives the universal joint 8 to rotate, so that the other lead screw 2 is also driven to rotate, and the lead screw 2 slides relative to the supporting leg 1 while rotating, so that the angle between the two supporting legs 1 is increased or decreased, so that the stability of the device and the height of the maintenance warning sign can be adjusted.

[0031] As shown in Figure 6 , the connecting plate 5 is divided into two parts from the middle, and the telescopic rod 6 is sleeved and fixed between the two parts of the connecting plate 5 by bolts.

[0032] In the technical solution, the connecting plate 5 is hollow, the telescopic rod 6 is sleeved in the connecting plate 5, the amplitude of the telescopic rod 6 is adjusted, and the distance between the two groups of supporting legs 1 is adjusted to adapt to maintenance warning signs of different sizes.

[0033] As shown in Figure 3 , the bottom of the supporting leg 1 extends outward to form an extension plate 4, and a hand screw 3 for adjusting the height is threadedly connected on the extension plate 4.

[0034] In the technical solution, by arranging the hand screw 3, when encountering uneven road surface, the hand screw 3 is twisted to adjust the rod part of the hand screw 3 to be in contact with the concave surface of the ground, so as to improve the applicability of the device.

[0035] Working principle: when the device is stored, the telescopic rod 6 is pulled out from the inside of the connecting plate 5 by loosening the bolt, the distance between the two supporting legs 1 is increased, the maintenance warning sign is removed, the two sliding seats 11 are respectively slid to the two ends of the sliding groove 9, the connecting plate 5 is tilted and moved into the sliding groove 9, at this time, the two groups of supporting legs 1 are pasted, then the screw rod 2 is screwed out of the supporting leg 1, the other opposite supporting leg 1 is opposite, at this time, the supporting leg 1 is sleeved on the connecting rod 7, because the diameter of the connecting rod 7 is small, the two mutually articulated supporting legs 1 can rotate freely, the two supporting legs 1 are rotated to coincide, at this time, the universal joint 8 is located in the concave surface 14.

[0036] The above is only a preferred embodiment of the present application, and does not limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the protection scope of the technical scheme of the present application.
