Abstract

The utility model discloses a manhole cover, and the matching position of the lower end of the manhole cover and a manhole port is fixedly provided with an anti-vibration rubber ring, wherein, for conveniently fixing the rubber ring, the matching position of the lower end of the manhole cover and the manhole port can be provided with an annular groove, and the rubber ring is arranged in the annular groove, and is exposed outside the annular groove. The manhole cover can prevent large noise sent out by the mutual crash of the manhole cover and the manhole port when pedestrians or vehicles pass through the manhole cover, and noise pollution is reduced.

Description

A kind of inspection shaft lid

The utility model relates to a kind of inspection shaft lid.

In the prior art, the inspection shaft lid that uses on the inspection shaft all is that directly lid is put at well head, because cooperating between inspection shaft lid itself and the well head has certain interval, when pedestrian or vehicle during through the inspection shaft lid, inspection shaft covers can be in the activity of well head place, cause collision mutually between inspection shaft lid and the well head, send the stronger sound, particularly at night, several especially pleasant, very clear, become the another noise pollution of modern metropolitan cities.

The purpose of this utility model is to provide a kind of inspection shaft lid, when avoiding pedestrian or vehicle through the inspection shaft lid, and the collision stronger sound that sends mutually between inspection shaft lid and the well head, minimizing noise pollution.

For reaching above-mentioned purpose, the utility model inspection shaft lid is to fixedly install a Shockproof rubber circle in the cooperation place of its lower end and well head, wherein, for this rubber ring convenient fixing, can offer a ring groove in the cooperation place that inspection shaft covers lower end and well head, rubber ring is arranged in this ring groove, and is exposed at outside the ring groove.

After adopting said structure, the utility model is compared with inspection shaft lid of the prior art, because of the cooperation place at inspection shaft lid lower end and well head has fixedly installed a Shockproof rubber circle, so when pedestrian or vehicle process inspection shaft lid, though inspection shaft lid can be in the activity of well head place, because the antihunt action of Shockproof rubber circle, cause that collision is weakened mutually between inspection shaft lid and the well head, avoided sending the stronger sound, reduced noise pollution.

Below in conjunction with drawings and Examples, the utility model done describing in further detail.

Fig. 1 is embodiment one a structure cut-away view of the present utility model;

Fig. 2 is embodiment two structure cut-away views of the present utility model.

See also shown in Fig. 1,2, cover the state cut-away view of putting at the well head place of inspection shaft for the utility model.

Earlier as shown in Figure 1, inspection shaft lid 1 is pasted by glue in the cooperation place of its lower end and well head 2, fixedly install a Shockproof rubber circle 3, like this, when pedestrian or vehicle cover 1 through inspection shaft, though inspection shaft lid 1 can be in well head 2 places activity, but because the antihunt action of Shockproof rubber circle 3, cause and collide weakenedly between inspection shaft lid 1 and the well head 2 mutually, avoided sending the stronger sound, reduced noise pollution.

Again as shown in Figure 2, for rubber ring 3 convenient fixings, also can offer a ring groove 11 in the cooperation place that inspection shaft covers 1 lower end and well

head

2,3 of rubber rings are set directly in this ring groove 11, and be exposed at outside the ring groove 11, fasten with glue and needn't make, greatly facilitate the fixing of rubber ring 3, make that assembling processing is more easy, and rubber ring 3 replacement after aging is also more convenient.

In addition, the utility model also can adopt the reinforced concrete moulding by casting, by adding the additive of different colours, can form decorative pattern miscellaneous on the surface, to have aesthetic property; And the inspection shaft lid cost of the existing cast iron of the inspection shaft of reinforced concrete moulding by casting lid is low, has antitheft effect again.

Claims

1, a kind of inspection shaft lid, it is characterized in that: the cooperation place of its lower end and well head fixedly installs a Shockproof rubber circle.

2, a kind of inspection shaft lid as claimed in claim 1, it is characterized in that: a ring groove is offered in the cooperation place of inspection shaft lid lower end and well head, and rubber ring is arranged in this ring groove, and is exposed at outside the ring groove.
