Abstract
The utility model belongs to a noise-proof and anti-pressure well cover. The noise-proof and anti-pressure well cover is mainly composed of a well cover body and a pipe wall, wherein the upper end of the outer side of the pipe wall is provided with an outward-flanging supporting edge which extends outwards, the outward-flanging supporting edge is provided with a groove, the edge portion of the well cover body covers the upper end dace of the outward-flanging supporting edge, and a gasket is installed between the well cover body and the groove. According to the noise-proof and anti-pressure well cover, noise produced when the well cover suffers pressure can be effectively avoided, and anti-pressure performance of the well cover is enhanced. Meanwhile, the noise-proof and anti-pressure well cover has the advantages of being simple in structure, strong in anti-pressure performance, easy to install and disassemble, long in service life and good in using effect.
Description
Technical field
The utility model belongs to a kind of anti-noise resistance to compression well lid.
Background technology
Traditional well lid underground structure (as shown in Figure 1) all is to adopt to be provided with convex edge 2 in the tube wall inner top side, and the upper end, convex edge is provided with well lid.This traditional project organization is because well lid both ends of the surface discontinuity, cause in use rocking easily when automobile rolls out-of-date well lid from the well lid surface, and the bigger noise of generation, living environment around not only having influenced, simultaneously well lid is owing to stressedly for a long time also easily cause damage, need change repeatedly, increase the expenditure cost that communal facility is safeguarded again.
Summary of the invention
The purpose of this utility model is a kind of anti-noise resistance to compression well lid of design, the noise that can effectively avoid well lid to produce when pressurized has strengthened the crushing resistance of well lid, also have simple in structure, crushing resistance is strong, easy installing/dismounting, the advantage of the advantage that long service life and result of use are good.
For this reason, the utility model mainly is made up of well lid and tube wall, and the tube wall outer upper end is provided with outward extending turning up and supports the edge, turns up to support along being provided with groove, and well lid limit portion covers to turn up and supports along on the upper surface, is provided with packing ring between well lid and the groove.Described packing ring adopts asbestos, or elastomeric material is made.The said structure design has realized the purpose of this utility model.
The noise that the utility model can effectively avoid well lid to produce when pressurized has strengthened the crushing resistance of well lid, also have simple in structure, crushing resistance is strong, easy installing/dismounting, the advantage that long service life and result of use are good.
Description of drawings
Fig. 1 is traditional well lid structural representation.
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of anti-noise resistance to compression well lid mainly is made up of well lid 1 and tube wall 3.The tube wall outer upper end is provided with outward extending turning up and supports along 6, turns up to support along being provided with groove 5, and well lid limit portion covers to turn up and supports along on the upper surface, is provided with packing ring 4 between well lid and the groove.Obviously the contact area that supports along with well lid limit portion of turning up of the present utility model increases considerably, and can effectively increase the load-bearing of well lid, has strengthened the crushing resistance of well lid, also can effectively reduce owing to the noise that produces is rocked in the little generation of both contacts area.
Described packing ring adopts asbestos, or elastomeric material is made.The noise that packing ring can effectively avoid well lid to produce when pressurized makes well lid stressed evenly, has strengthened the crushing resistance of well lid, has prolonged the application life of well lid.
During use, when the well lid surface is under pressure, packing ring between well lid and the groove can be eliminated the noise that well lid rocks generation, and can alleviate well lid and be stressed, strengthened the crushing resistance of well lid, the noise that the utility model in use can effectively avoid well lid to produce when pressurized makes well lid stressed evenly, strengthen the crushing resistance of well lid, prolonged the application life of well lid.
In a word, the noise that the utility model can effectively avoid well lid to produce when pressurized has strengthened the crushing resistance of well lid, also have simple in structure, crushing resistance is strong, easy installing/dismounting, the advantage that long service life and result of use are good.
Claims (2)
