Example Embodiment

[0017] Example 1

[0018] As attached figure 1 , Attached figure 2 The illustrated manhole cover with warning function includes a ring seat 1, a stepped annular bearing surface 2 provided on the inner wall of the ring seat 1, and a manhole cover 8 covered on the ring seat 1 and supported by the ring bearing surface 2. The inner wall of the ring seat 1 is provided with a warning device, the warning device includes a fixing seat 3, the fixing seat 3 includes a back plate 3-1, ear plates 3-2 arranged on both sides of the back plate 3-1, and fixing The fixed shaft 4 between the two lug plates 3-2 is sleeved with a support rod 6 and a return spring 5 that can reset 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 A warning sign 7 is provided on the upper end of the warning sign 7, and the war...

Example Embodiment

[0021] Example 2

[0022] The manhole cover with warning function described in this embodiment differs from embodiment 1 only in the return spring 5, as 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 fixedly connected to the support rod 6. When the manhole cover 8 is covered on the ring seat 1, the manhole 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 manhole cover 8. At this time, the tension spring is stressed. When the manhole cover 8 is removed , Under the action of the tension spring, the support rod 6 springs up and returns to a vertical state, so that the warning sign 7 extends 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.

Description

technical field [0001] The invention relates to a well cover with warning function. Background technique [0002] Traditional manhole covers have through holes and no anti-theft measures, so they are easily stolen by thieves with simple tools.
