Description

Technical Field

[0001] The utility model relates to a stainless steel manhole cover for municipal roads, belonging to the technical field of road manhole covers. Background Art

[0002] Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has stainless properties is called stainless steel. Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc.

[0003] The utility model with patent number 202120241101.3 provides a stainless steel manhole cover for municipal roads. The stainless steel manhole cover for municipal roads activates its anti-vibration device through the pressure of the car passing by. The springs on both sides of the anti-vibration device are forced to drive the elastic rod to move downward. At the same time, under the influence of the pressure of the fixed sleeve, the spring in the middle drives the elastic rod to move upward, thereby improving the balance of the manhole cover when under pressure, improving the shock resistance of the manhole cover, reducing the noise and shaking caused by the pressure caused by people coming and going, and having a certain degree of safety; however, the existing road manhole covers serve as drainage, and the random manhole cover positions will often be soaked in rainwater, and some complex fixed structures in the manhole cover are easily eroded after encountering rainwater, which has a certain impact on subsequent use and reduces the service life of the manhole cover. In addition, garbage and debris on the road will also enter the sewer with rainwater, which can easily cause blockage of the manhole cover or the sewer. The manhole cover needs to be opened frequently for cleaning, which is inconvenient to operate. Utility Model Content
