Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to an improved decorative manhole cover. Background Art

[0002] At present, in paved square areas with high landscape requirements such as plazas outside commercial complexes and newly built communities, a decorative manhole cover is generally installed on the cast iron or polymer resin manhole cover of the water and electricity inspection well to enhance the landscape effect of the entire pavement. There is a lifting hole on the decorative manhole cover, and the maintenance personnel extend the lifting rod with a bent end into the lifting hole to open the decorative manhole cover. However, after a long time, the lifting hole is easily filled with various dust and debris. Before the push-pull rod is put into the lifting hole, the lifting hole needs to be cleaned, which is very inconvenient. At the same time, since most decorative manhole covers are square in shape, they can be freely placed on the base of the decorative manhole cover, which easily makes the decorative plate on the manhole cover inconsistent with the paved ground.

[0007] An elastic baffle is provided at the lower end of the pulling hole.

[0008] Through the above technical scheme, the decorative panel is placed or fixed in the manhole cover body, and the manhole cover body can be pulled upward by extending the pull rod with a bent end into the tie hole; an elastic baffle is arranged under the tie hole to effectively prevent dust, garbage, etc. from entering the corresponding triangular cavity. When it is necessary to extend the pull rod into the tie hole, there is no need to clean the tie hole, which can facilitate later maintenance personnel to open the decorative manhole cover.

[0009] The utility model is further configured as follows: three straight sides of the elastic baffle are arranged parallel to the three inner walls of the triangular cavity and maintain a spacing of 2 to 5 mm;

[0010] The elastic baffle is fixed on a plurality of springs arranged vertically therewith, and the lower ends of the springs are fixed on the bottom surface of the square short box.

[0011] Through the above technical solution, the elastic baffle can move up or down along the inner wall of the triangular cavity. The spring can make the elastic baffle move down when under pressure, and automatically move up and reset to be close to the lifting hole when not under pressure.

[0012] The utility model is further configured as follows: the manhole cover base includes a square frame, a supporting bottom plate is provided at the bottom of the square frame, and a clearance hole is formed in the middle of the supporting bottom plate;

[0013] The square short box is inserted into the square frame.

[0014] The upper end surface of the square short box is flush with the upper end of the square frame, so that there is no height difference between the manhole cover body and the manhole cover base, thereby preventing stumbling.

[0015] A 4-7 mm gap is left between the outer wall of the square short box and the inner wall of the square frame, so that the square short box can be easily removed from the square frame.

[0016] The utility model is further configured as follows: positioning holes are formed on the bottom surfaces of the triangular cavities corresponding to the other two lifting plates, and short positioning pins are sleeved in the positioning holes, and the short positioning pins are fixed on the supporting bottom plate.

[0017] Through the above technical solution, the manhole cover body can be placed in the manhole cover base with position requirements, which can effectively prevent the manhole cover body from being misplaced and affecting the overall coordination of the ground surface.

[0018] The utility model is further configured as follows: a guide cone is formed on the upper end of the positioning short pin.

[0019] Through the above technical solution, the positioning hole can be conveniently inserted into the positioning short pin through the guide cone.

[0020] The outstanding effects of the utility model are:

[0021] Compared with the existing technology, the elastic baffle can effectively prevent sand, dust and other debris from entering the tie hole, which can facilitate the later removal and placement of the manhole cover body; the positioning short pin can limit the position of the manhole cover body into the manhole cover base, which can effectively prevent the occurrence of misplacement.
