Embodiment Construction

[0014] Attached below Figure 1-2 Embodiments of the present invention are described.

[0015] Anti-fall sewer manhole covers, such as figure 1 and 2 As shown, it includes a ring frame 1 adapted to the edge of the road circular well hole and a circular cover plate 2 snapped into the ring frame 1. The outer step 101 in the ring frame 1 is formed with an inner step 102 for supporting the circular cover plate 2 on the upper edge of the inner surface of the ring frame 1 . The upper end surface of the circular cover plate 2 is provided with a pull ring 5 .

[0016] Between the lower part of the inner surface of the ring frame 1 and the lower end surface of the circular cover plate 2, the circular cover plate 2 can be straightly supported on the upper part of the ring frame 1 and can be elastically bent so that the circular cover plate 2 can be inserted into the ring. The elastic bending support plate 3 in the frame 1 is connected, and a plurality of water holes 301 are evenly f...

Abstract

The invention provides an anti-drop type sewer manhole cover, the anti-drop type sewer manhole cover comprises an annular frame adapted to the edge of the circular well hole of the road and a circularcover plate embedded in the annular frame, the lower part of the inner surface of the annular frame and the lower end surface of the circular cover are connected through an elastically bent support plate capable of directly supporting the circular cover plate on the annular frame and embedding the circular cover plate into the annular frame by elastic bending, and multiple drain holes are uniformly arranged on the elastically bent support plate. The anti-drop type sewer manhole cover not only can effectively drain water in the rainy day, but also can prevent safety an accident caused by pedestrians falling into the sewer and has the advantages of simple structure and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of manhole covers, in particular to an anti-drop type sewer manhole cover. Background technique [0002] Manhole covers can be seen everywhere in urban construction. They are used to cover roads and prevent people or animals from falling. According to the material, manhole covers are divided into metal manhole covers and high-strength limit cement concrete manhole covers. Manhole covers are mostly round and set on sidewalks, motorways, alleys and other places. The existing well cover has such a problem in the use process; when the staff opens the well cover to release water in rainy days, when the water is deep and the water surface will cover the well mouth, pedestrians cannot see the ground, and the problem of falling into the well will occur, causing personal injury. security incident. Therefore it is necessary to propose improvements. Contents of the invention [0003] The technical problem solved b...
