Problems solved by technology

[0002] Traditional manhole covers have through holes and no anti-theft measures, so they are easily stolen by thieves with simple tools. After the manhole cover is stolen, the exposed wellhead becomes a trap on the road, which seriously threatens the safety of pedestrians and vehicles.
After the manhole cover is lost, there are no measures to remind, and there are no measures to prevent accidents, especially at night, it is not easy to be found, often causing accidents of car crashes

Embodiment 1

[0018] as attached figure 1 , attached figure 2 A manhole cover with a warning function is shown, including a circle seat 1, a stepped annular bearing surface 2 arranged on the inner wall of the circle seat 1, and a manhole cover 8 covered on the circle seat 1 and supported by the annular bearing surface 2. The inner wall of the ring seat 1 is provided with a warning device, and the warning device includes a fixed seat 3, and the fixed seat 3 includes a back plate 3-1, ear plates 3-2 arranged on both sides of the back plate 3-1 and fixed The fixed shaft 4 between the two ear plates 3-2, the fixed shaft 4 is sleeved with a support rod 6 and a return spring 5 capable of resetting the support rod 6, as attached figure 2 As shown, the return spring 5 is a torsion spring sleeved on the fixed shaft 4, the support rod 6 is hinged with the fixed shaft 4, the support rod 6 can rotate on the fixed shaft 4, and the support rod The upper end of 6 is provided with a warning sign 7, whi...

Embodiment 2

[0022] A manhole cover with a warning function described in this embodiment differs from Embodiment 1 only in that the return spring 5, as shown in the attached image 3 As shown, the return spring 5 is a tension spring arranged between the back plate 3 - 1 and the support rod 6 , and the tension spring is fixedly connected to the back plate 3 - 1 and to the support rod 6 . When the well cover 8 is covered on the ring seat 1, the well cover 8 presses the warning sign 7 and the support rod 6, so that the support rod 6 and the warning sign 7 are located under the well cover 8. At this time, the tension spring is stressed. When the well cover 8 is removed , under the action of the extension spring, the support rod 6 springs up and resets, and is in a vertical state, so that the warning sign 7 stretches out of the ring seat 1.

Abstract

The invention relates to a manhole cover with a warning function. The manhole cover comprises a seat ring, a circular bearing face, and a cover body; the circular bearing face in a step form is arranged on the inner wall of the seat ring; the cover body covering the seat ring is supported through the circular bearing face. The inner wall of the seat ring is provided with a warning device which can pop up and be pressed down. After the cover body is lost, the manhole cover can remind vehicles and passengers for avoiding the danger, and traffic accidents caused by loss of manhole covers can be greatly decreased. The manhole cover is highly practicable.
