Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, an example during each feature is a series of equivalence or similar characteristics.
nullAs shown in Figure 1，A kind of municipal administration noise reduction anti-stealing manhole cover of the present utility model，Including inspection shaft 8 and inspection well cover 4，It is provided with a mounting groove 5 in the middle of described inspection well cover 4，Described inspection well cover 4 upper end is provided with an opening 3，This opening 3 communicates with mounting groove 5，An air bag 1 it is provided with in described mounting groove 5，An air valve 2 is fixedly mounted on this air bag 1，Described air valve 2 is arranged in opening 3，Both sides, described mounting groove 5 lower end are equipped with an arcuate groove 12，This arcuate groove 12 is inclined to set，Described arcuate groove 12 lower end is equipped with one first angling hole 15，This first angling hole 15 all communicates with arcuate groove 12，Described first angling hole 15 lower end communicates with the external world，A ball 13 it is equipped with in described arcuate groove 12，Described ball 13 lower end is fixedly connected with one and fixes bar 16，Arcuate groove 12 all worn by this fixing bar 16 and the first angling hole 15 extends to the external world，Described fixing bar 16 is positioned at ball 13 junction and is equipped with a spring 14，This spring 14 upper surface is all mutually low with the lower surface of ball 13，This spring 14 lower surface all offsets with arcuate groove 12 bottom surface.
In the present embodiment, lower end, described inspection well cover 4 outer ring forms a groove structure, fixedly mounts more than one relief spring 7, all fixedly mount a hydraulic bar 9 in this relief spring 7 in groove structure.
In the present embodiment, around inspection shaft 8 one circle fixed installation one fixed block 11 in described inspection shaft 8, this fixed block 11 upper surface is provided with a relief groove 10 around fixed block 11 1 circle, described fixed block 11 inner ring both sides all fixedly mount a fixture block 18, this L-shaped setting of fixture block 18, being equipped with one second angling hole 17 on described fixture block 18, these the second angling hole 17 two ends all communicate, and arrange in straight line between described second angling hole 17 and the first angling hole 15；The relief spring 7 of described inspection well cover 4 lower end is mutually low with fixed block 11 upper surface, and described hydraulic bar 9 lower end offsets with relief groove 10 bottom surface.
Operation principle: during installing inspection well cover, first the hydraulic bar of inspection well cover lower end is alignd in the relief groove being placed into inspection shaft, the relief spring making its inspection well cover lower end is mutually low with fixed block, the friction between inspection well cover and inspection shaft can be effectively reduced by relief spring and hydraulic bar so that it is the sound that the service life of inspection well cover increases and inspection well cover sends reduces during vehicle leaves.
Wherein, after placing inspection well cover, inflated in the air bag in inspection well cover by special pump-up device, along with the gas in air bag is the most, ball can be gone by air bag toward arcuate groove is intrinsic pressure, make the fixing bar that its arcuate groove lower end connects to bottom offset, until fixing bar inserts in the angling hole on fixture block, at this moment, inspection well cover is fixed on inspection shaft the most completely, otherwise, as long as the gas in air bag is released, just fixing bar can be ejected in angling hole by the spring of ball lower end, thus inspection well cover can be picked up.
The beneficial effects of the utility model are: this utility model simple in construction, and easy for installation, Financial cost is low, applied widely, can effectively prevent inspection well cover from making too much noise and can effectively prevent inspection well cover stolen.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
