Warning board for electric power construction

Abstract

This utility model discloses a warning sign for power construction, comprising a construction sign, a rotating frame, a fixed frame, and a support rod. The construction sign can be fixed to the rotating frame by hand-tightening screws and nuts. The rotating frame is provided with a convex shaft, and the fixed frame is provided with a bearing. The outer wall of the convex shaft is fixed to the inner wall of the bearing. The support rod is fixed to a fixed block, which can be fixed to the fixed frame by hand-tightening screws and nuts. The support rod is provided with a threaded fastening point, which cooperates with the fastening sleeve to fix the support feet.

The rotating frame has convex shafts fixedly connected to its two outer side walls. A groove is formed in the inner wall of the rotating frame, and the inner wall of the groove is slidably connected to the outer wall of the construction sign. A handle is fixedly connected to the upper surface of the construction sign. A through hole one is formed in the lower center of the construction sign. A through hole two is formed in the lower center of the rotating frame. Through holes three are formed in the two side walls of the fixing frame. Bearings are fixedly connected to the inner walls of the through holes three. Through holes four are formed near both ends of the lower part of the fixing frame. The outer wall of the convex shaft is fixedly connected to the inner wall of the bearing.

[0006] The support rod is fixedly connected to a fixing block at one end near the construction sign. The fixing block has a through hole five on its side wall. The support rod has a threaded fastening part at its end. The support foot is slidably connected to the inner wall of the support rod. The fastening sleeve is threadedly connected to the outer wall of the threaded fastening part. A conical cylinder is fixedly connected to the end of the fastening sleeve away from the through hole five. The inner wall of the conical cylinder is slidably connected to the end surface of the threaded fastening part. The outer wall of the support foot is slidably connected to the inner wall of the threaded fastening part.

[0007] According to the aforementioned warning sign for power construction, a hand-tightening screw is slidably connected to the inner wall of the first through hole, and a hand-tightening nut is threadedly connected to the outer wall of the hand-tightening screw. The first through hole and the second through hole are fixedly connected by the hand-tightening screw and the hand-tightening nut.

[0008] According to the aforementioned warning sign for power construction, the through hole four and through hole five are fixedly connected by a hand-tightened screw and a hand-tightened nut.

[0009] According to the aforementioned warning sign for power construction, a first screwing block is fixedly connected to the unthreaded end of the hand-tightening screw, and a second screwing block is fixedly connected to the outer wall of the hand-tightening nut.

[0010] According to the aforementioned warning sign for power construction, the number of the two screw blocks is two and they are symmetrically distributed on the outer wall of the hand-tightening nut.

[0011] According to the aforementioned warning sign for power construction, the threaded fastening part is divided into four evenly spaced sections to facilitate engagement with the fastening sleeve for fastening the support foot. The outer wall of the fastening sleeve has a frosted surface to increase friction and facilitate the application of force.

[0012] According to the aforementioned warning sign for power construction, the end of the support leg furthest from the support rod is spherical to adapt to different terrains.

[0013] According to the aforementioned warning sign for power construction, there are two fixing blocks and four support rods, with two support rods symmetrically distributed on both sides of each fixing block.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. The rotating frame works in conjunction with the fixed frame, so that it will sway with the wind in extreme weather such as strong winds, rather than causing the entire frame to shake. This can effectively prevent the power construction warning sign from being blown down by the wind to a certain extent.

[0016] 2. Tighten the fastening sleeve to manually adjust the height of the support feet. After adjustment, tighten the fastening sleeve. This allows the sign to be placed on various uneven ground surfaces, making the power construction warning sign more stable.
