Abstract
The utility model discloses a manhole cover, which comprises an upper cover and a lower matched with the same. The upper cover and the lower cover are mounted together so that a chamber is formed, and a heat insulation layer is arranged in the chamber. The manhole cover is in a double-layer structure, the heat insulation layer is formed in the chamber, and thereby affection of external temperature to articles in a tank is prevented effectively, quality of conveying containerized tanks is improved, and loss of the articles in the conveying process is reduced.
Description
Technical field
The utility model relates to a kind of manhole cover.
Background technology
Bulk bin and tank container are similar, but do not belong to collection dress series, but constitute special-purpose series separately, and its collection dress ability surpasses tank container sometimes.This collection dress mode has cement bulk jar and oil, two representative types of fuel oil drum to represent system.
Being provided with manhole on bulk bin is convenient to the people and enters in the jar and clear up.On manhole, be provided with manhole cover, be used at charging rear enclosed manhole.
And existing manhole cover is a single layer structure, and does not possess effect of heat insulation, causes jar interior article temperature influence bigger.
The utility model content
The technical problems to be solved in the utility model is to be single layer structure in order to overcome bulk bin manhole cover of the prior art, and does not possess effect of heat insulation, causes jar interior article to be vulnerable to the defective of temperature effect, and a kind of manhole cover that is used for bulk bin or tank car is provided.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of manhole cover, its characteristics are that it comprises: a loam cake and one and the adaptive lower cover of described loam cake, described loam cake and described lower cover assembling back form a chamber, are provided with a thermal insulation layer in described chamber.
Wherein, described loam cake and described lower cover are clamping.
Wherein, the edge of described loam cake is provided with a flange, the described protuberance that is provided with described flange clamping that covers down.
Wherein, described flange and described protuberance are annular.
Wherein, described thermal insulation layer adopts foamed materials, lamination coating or vacuum material to make.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
Positive progressive effect of the present utility model is: manhole cover of the present utility model adopts double-decker, and in chamber, form a thermal insulation layer, effectively prevent the influence of external temperature, improved the shipping mass of bulk bin, reduce the article loss in the transportation article in the jar.
Description of drawings
Fig. 1 is the cutaway view of manhole cover of the present utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, manhole cover of the present utility model comprises a loam cake 1 and a lower cover 2, and this loam cake 1 is connected with the mode of lower cover 2 by clamping.Particularly, be provided with the flange 11 of downward turnover at the edge of loam cake 1, then be provided with the protuberance 21 adaptive with the flange 11 of loam cake 1 on the lower cover 2, this flange 11 and protuberance 21 are annular.By flange 11 and protuberance 21, loam cake 1 and lower cover 2 are connected together.
After this loam cake 1 and lower cover 2 assemblings, form a chamber 3 between the two.In chamber 3, be equipped with the thermal insulation layer made from foamed plastic.Certain described thermal insulation layer also can adopt vacuum material or lamination coating to make.Described vacuum material and described lamination coating are prior art, do not repeat them here.
Though more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that these only are casehistorys, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
