The utility model relates to a kind of deodorization sealing manhole cover of all kinds of cell body special uses such as various pipes such as indoor piping, sewer pipe and hopper, sump.

Why manhole cover is adopted widely, mainly is can be applicable to hopper, sump, rhone, rainwater lid, heat storage tank and be embedded in the electrical cable of underground pipeline or sewer or the like because of it.Manhole cover is generally all cylinder iron made, but there are following many shortcomings in it: (1) cable adopts manhole cover, immerses water easily, influences result of use, disturbs as producing; (2) water purification in the hopper if there is sewage to immerse through manhole cover, then must treatedly can be drunk; (3) manhole cover is as the sewage lid, and as the septic tank lid, easily because of fermentation, oxidation produce biogas and leak, especially the various medicines of general chemical plant more need have the deodorization sewage lid of complete seal and have the sealing usefulness that prevents that export-oriented sewage from flowing into; (4) if cause the energy to run off, then more to note at industrial used heat storage tank because of leaking; (5) general cover-lifting type manhole cover is easily stolen by the people.

At existing manhole cover above shortcomings, the purpose of this utility model is a kind of energy deodorization, sealing to be provided and can to prevent stolen manhole cover.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 adopts the generalized section of the present utility model of Hua Bingxing (Y type) for packing ring;

Fig. 2 adopts banana type (f type → extend out) generalized section of the present utility model for packing ring;

Generalized section when Fig. 3 adopts the utility model manhole cover of flower and type to take out for packing ring;

Fig. 4 is the floor map of precession of the utility model manhole cover or back-out.

Referring to accompanying drawing, solution of the present utility model is as follows. It still has manhole cover body 3, base 2 and rubber washer 4, and its feature part is, base 2 is for ring-type and have staged concavity groove, the central authorities of the interior ring 21 of base 2 are scrobicular ring hole 22, the rubber washer 4 of scrobicular ring hole 22 interior insertion retainer ring shapes, rubber washer 4 can be Hua Bingxing (Y type), also can be Banana Type (f type), and the outer shroud of base 2 has stepped circular groove 23, annular groove 24 formed space segments between interior ring 21 and the circular groove 23 are then as hopper, and the outer shroud of manhole cover body 3 bottoms is processed into two jiaos of hook 31(referring to Fig. 1 to Fig. 3); At the periphery of base 2, namely opening slightly is provided with short slot 32(that two jiaos of hooks 31 of tolerated towards others port lid body 3 bottoms of equidistant annular arrangement insert referring to Fig. 4 in the lower end); Both sides, manhole cover body 3 top has circular hole 33, is connected with round bar 34 in the circular hole 33, also has simultaneously can stretch in the circular hole 33 fastener and live in the hook bar 35(of round bar 34 referring to Fig. 3 and Fig. 4).

Referring to Fig. 1 and Fig. 2, have the utility model of said structure when installing and using, with jag spike 25 base 2 is connected on the pedestal 1 that needs installing manhole cover place. As previously mentioned, because manhole cover body 3 is the cast iron manufacturing, weight own is big, so the rubber washer 4 that its bottom weight becomes the Y type or becomes the f type extends out packing ring 4, produces sealing function, thereby can prevent effectively that sewage from can not enter or foul smell is unlikely and leaks.

Referring to Fig. 3, behind the round bar 34 in the hook bar 35 fastener manhole cover bodies 3 top circular holes 33, manhole cover body 3 is hooked, two jiaos of hooks 31 of the body of manhole cover shown in Fig. 1 to Fig. 33 bottoms are aimed at the short slot 32 of base 2, manhole cover body 3 is fallen in the base 2, and pin adds rotation then, makes two jiaos of hooks 31 by circular groove 23 clinchings, can prevent that manhole cover body 3 is stolen, because common people's port lid system is with the direct pull-up of the hand draw ring on top.Obviously, desire to open the Access Opening and cover body 3, the short slot 32 that then it must be threaded to two jiaos of hooks, 31 aligning bases 2 can be pulled upwardly.The time spent should not taken out the receipts pipe to hook bar 35 from circular hole 33.

In sum, the utility model is a kind of structure that opens and closes alone as can be known, can prevent that sewage from being immersed in the manhole cover by the outside, or prevent to release foul smell or liquid by inside, and prevent stolen, its novel structure, reasonable in design, can extensively replace the manhole cover that has various occasions now.
