Abstract
The utility model discloses a damping anti-theft launching cover, which is characterized in that annular ports for passing water are arranged at the central position of the roof board, a buffer layer is painted on the junction platform of the chassis, an 'A' type die-pin is provided between the junction platforms, the roof board is fixed with the chassis via the special anti-theft thread with a irregular circular shape top, the utility model can only be opened by a special tool. The utility model has the advantages of anti-theft, drainage, damping, reducing noise, rust-proofing and good fixing effect, thereby the utility model is widely used in the urban public facility construction.
Description
The utility model belongs to a kind of communal facility (Sewage well cover), the antitheft water cover down of particularly a kind of damping.
Existing Sewage well cover mainly is made up of top cover and base, and air-vent is set on the top cover.Do not have fixation means between top cover and the base, easily stolen, easily upset causes the injures and deaths or the infringement of personnel and vehicle.No damping facility between top cover and the base, vehicle crosses on well lid, and vibrations are big, and noise is big, influences surrounding environment, easily gets rusty between top cover and the base simultaneously, is difficult to open.Air-vent is less on the top cover, and normally draining in rainy season if raise the well lid draining, was both required great effort, and security incident takes place again easily.
In view of the foregoing, the purpose of this utility model is to provide a kind of damping, noise reduction, antirust, draining, the antitheft water cover down of damping antitheft, good fixing effect.
The purpose of this utility model is achieved in that it is made up of top cover, base, special-purpose anti-theft screw, the position that is isosceles triangle on the top cover is provided with screw hole A, the center is provided with the annular row water hole, and the back side is " Y " shape fin is set, and the fin infall is a circular hole; The position that is isosceles triangle on the base is provided with the connection platform, connects the platform surface and scribbles buffer layer, and screw hole A place of corresponding top cover is provided with screw hole B on it, and top cover and base relevant position are provided with marker line, connects " A " type pressure pin is set between the platform; Fix by special-purpose anti-theft screw between top cover and the base, the top of special-purpose anti-theft screw is an irregular cycle, is used with special tool.
The utility model is compared with existing Sewage well cover, and the annular row water hole is set on the top cover, and drainage effect is good; Scribble buffer layer on the connection platform of base, when vehicle crosses, alleviate concussion, reduce noise, prevent to get rusty between top cover and the base well lid; Connect setting " A " type pressure pin between the platform, prevent the top cover upset and crash into the shaft bottom; Fix with special-purpose anti-theft screw between top cover and the base, must use special tool to open, prevent that top cover is stolen.
Further specify the utility model and embodiment below in conjunction with accompanying drawing.
Figure one is the utility model structural representation;
