Effect prevents dust or rainwater from entering into well, damage is caused to the equipment in well, while can play cushioning effect to prevent from making an uproar
The waterproof and dustproof of sound, noiseproof manhole cover.
To reach above-mentioned purpose, the utility model uses following technical scheme, a kind of waterproof and dustproof, noiseproof manhole cover, bag
Include base and upper well lid；Described upper well lid is embedded on base, and the upper surface of upper well lid is located at together with the upper surface of base
In one plane, flexible steel ring and the sealing ring concentric with upper well lid, described elasticity are provided between described base and upper well lid
Steel ring is fixed and is located on base, and described sealing ring is fixedly connected on flexible steel ring, and the base is contacted with upper well lid bottom
Face be provided with the circle cushion seal circle concentric with upper well lid.
Described cushion seal circle is section for the rubber parts of v-shaped structure, and the V-arrangement rubber parts are embedded in base and are provided with
Annular groove in.
Described cushion seal circle is the rubber parts that section is I-shape construction, and the I-shaped rubber parts is embedded in base
In the annular groove being provided with.
The section of described cushion seal circle is trapezium structure, and the trapezoidal rubber parts is embedded in the annular that base is provided with
In groove.
A circle steel ring is also arranged with described upper well lid.
The beneficial effects of the utility model are：Simple structure, the flexible steel ring being provided between base and upper well lid and close
Seal can effectively prevent rainwater or dust from entering within the border, close particularly when upper well lid is not put on base
External diameter of the internal diameter of seal less than upper well lid, it is ensured that when well lid is put on base, in steel rim of spring and the work of sealing ring
Under, upper well lid can seal basis with sealing ring, and sealing is good, and the equipment in well can be protected, and what is be provided with is slow
Rushing sealing ring has certain elasticity, it can be ensured that car is buffered when by well lid between well lid and base, relatively low to make an uproar
Sound, while extending the service life of well lid, reduces the maintenance cost of well lid.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment 1
Such as a kind of waterproof and dustproof in Fig. 1,2,3, noiseproof manhole cover, including base 1 and upper well lid 2；Described upper well lid 2 is inlayed
It is embedded on base 1, and the upper surface of upper well lid 2 is in the same plane with the upper surface of base 1, described base 1 and upper well
The flexible steel ring 3 and sealing ring 4 concentric with upper well lid 2 is provided between lid 2, described flexible steel ring 3 is fixed and is located on base 1,
Described sealing ring 4 is fixedly connected on flexible steel ring 3, the face that the base 1 is contacted with the bottom of upper well lid 2 be provided with a circle with
The concentric cushion seal circle 5 of upper well lid 2.
Sealing ring 4 as shown in Figure 3 is contacted with the perimetral tight of upper well lid 2, and well lid 2 connects with the sealing of base 1 in realization
Connect and avoid rainwater or dust from entering into well, cause to damage, particularly, flexible steel ring 3 and base 1 to the equipment in well
Inner ring (placing the space of upper well lid) is fixedly connected, and with certain elasticity, sealing ring 4 is fixed on flexible steel ring 3, is not being had
Before installing well lid, the internal diameter of the internal diameter less than upper well lid 2 of sealing ring 4, when upper well lid 2 is placed, the compression of upper well lid 2
Flexible steel ring 3 compresses it, and then upper well lid 2 is pressed onto on base 1, and flexible steel ring 3 has certain tension force, by sealing ring 4
Push out, form sealing ring 4 and be in close contact with the surrounding of upper well lid 2, realize sealing, effectively avoid rainwater or dust is logical
