The specific embodiment
Be described in further detail below in conjunction with the utility model of embodiment, but embodiment of the present utility model is not limited thereto.
Embodiment:
Fig. 1 is the structural representation of inspection shaft lid in the prior art, as shown in Figure 1, the well seat contacts for rigidity with well lid, between no any padded coaming, the combination between well seat and the well lid is defective tightness also, therefore, being subjected to that the pedestrian tramples or vehicle when rolling, usually can send sound of movement, cause unnecessary noise to pollute, especially for the inspection shaft Gai Eryan of metal species, its noise pollution is bigger; And owing to arranging of difference in height between present many well seats and the well lid is generally lack of standardization, its numerical value often greater than the regulation error range, therefore, in actual application, tend to cause jolting of driving, to such an extent as to have a strong impact on comfort level and the traffic safety of driving.For addressing the above problem, the utility model proposes a kind of embedded noise reduction inspection shaft lid, its structure as shown in Figure 2, also mainly formed by well seat 1 and the well lid 2 that is positioned on the well seat 1, well seat 1 is the fixture that circumferentially arranges along the manhole well head, be provided with crib at well seat 1,2 of well lids are positioned in the crib.And in said structure, the utility model has also proposed the design of buffering rim strip 3, be arranged on the bottom and side of well lid 2, can be used for alleviating the rigidity contact between well lid 2, the well seat 1, improve the driving comfort level of vehicle, reduced more that vehicle rolls when well lid 2 contacts with well seat 1 in the process and the sound of movement of sending, overall structure is very simple.
As shown in Figure 3, when buffering rim strip 3 is arranged at the bottom of well lid 2, well lid 2 is positioned in the crib by buffering rim strip 3, can not only effectively avoid direct contact of well seat 1 and well lid 2 bottoms, improve the shockproof properties of well lid 2, also can be used for reducing the difference in height of well seat 1 and well lid 2, improve the planeness on road surface, to reach purposes such as improving comfort level that vehicle travels and traffic safety, its structure is as follows: the groove 4 that is provided with fixing buffering rim strip 3 in the bottom of well lid 2, in the utility model, well seat 1 is for being provided with the circulus of emptying aperture, crib then is arranged at the inboard of well seat 1 and structure in the form of a ring along emptying aperture, and buffering rim strip 3,4 of grooves all arrange along crib and are identical shaped with crib, and hence one can see that, buffering rim strip 3, the structure of groove 4 also is circulus, the top end face of buffering rim strip 3 is connected in the groove 4, and its bottom then extends to outside the groove 4 and with the placement of well lid 2 and contacts with the crib base.In this structure, buffering rim strip 3 extends to the difference in height that groove 4 outer parts then can remedy well lid 2 and well seat 1 just, and the top end face of well lid 2, well seat 1 all is positioned on the same horizontal plane, improves the planeness on road surface.When vehicle rolls the inspection shaft lid, the bottom of well lid 2 and well seat 1 also cushion by buffering rim strip 3, improved the shockproof properties of well lid 2, further improved the comfort level that vehicle travels, in the time of also can eliminating vehicle and roll, well lid 2 bottoms contact with well seat 1 and the sound of movement sent, have fabulous erasure effect.
For better fixing buffering rim strip 3, improve the stability of using, groove 4 can be designed to oat tail groove structure, that is: its cross section is that the bottom land width is greater than the swallowtail-shaped structure of width of rebate, can make the clamping of buffering rim strip 3 more firm by the design of dwindling notch, as shown in Figure 4, whole groove 4 is structure in the form of a ring, and part is the bottom land of groove 4 shown in the dotted line.
Except the buffering rim strip 3 of being located at well lid 2 bottoms, the utility model still is provided with buffering rim strip 3 at well lid 2 sides, can be used for cushioning well lid 2 sides contacts with the rigidity of well seat 1, shockproof to realize, functions such as noise reduction, its structure as shown in Figure 3, well lid 2 structures in the form of annular discs, this buffering rim strip 3 is arranged on the circumference side of well lid 2, in actual application, the space is not had in combination between well lid 2 and the well seat 1 again, well lid 2 can closely be connected in crib by the buffering rim strip 3 that is arranged on the side on the contrary, as shown in Figure 3, the circulus of this buffering rim strip 3 for arranging along well lid 2 circumferential edge also is provided with the groove 4 of this buffering rim strip 3 of clamping on the circumferential edge of well lid 2.When making, the inner ring of buffering rim strip 3 can be connected in the groove 4, the outer ring then extend to groove 4 outer and with the placement of well lid 2 with the side phase clamping of crib.By said structure as can be known, shockproof function of the present utility model has further been strengthened in the design that is provided with the buffering rim strip 3 of side, since between existing well seat 1 and the well lid 2 in conjunction with defective tightness, after even the buffering rim strip 3 of shockproof, noise reduction is installed in well lid 2 bottoms, the vibrations of well lid 2 also may appear when vehicle rolls, its side then contacts and makes a noise with well seat 1, therefore, also only be provided with under the situation of buffering rim strip 3 antidetonation, the erasure effect of the utility model competence exertion maximum simultaneously at well lid 2 bottoms, side.In the utility model, be located at the groove 4 of well lid 2 sides, its structure also can be arranged to cross section be the bottom land width greater than the swallowtail-shaped structure of width of rebate, make the clamping of being located at the buffering rim strip 3 on well lid 2 sides more firm.
The utility model is simple in structure, can process the structure of two grooves 4 on existing well lid 2, and is simple, convenient, more avoided the waste of existing resource, the more effective management cost that reduces urban road maintenance.In actual mechanical process, can leave the dovetail groove of different specification size by machine tools, the buffering rim strip 3 that 2 size production and processings go out plurality of specifications according to well lid satisfies combining closely of well lid 2 and crib side respectively; According to the buffering rim strip 3 of well lid 2 with the difference in height production and processing plurality of specifications of crib, to satisfy the planeness on road surface.During use, also can have advantages such as easy to use, quick for installation according to the supporting use of field condition.
In the utility model, buffering rim strip 3 can adopt rubber to be made, as: the high-performance rubber rim strip.The utility model can not only reduce the difference in height of well seat 1 and well lid 2, improves the driving comfort level on road surface, also can avoid the vehicle to roll the noise that occurs in the process, have reasonable in design, manufacture craft is simple, advantage such as quick for installation, with low cost.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all falls within the protection domain of the present utility model any simple modification, equivalent variations that above embodiment does.
