Of the present utility model propose a kind of shield receptions sealing steel bushing, overcome the deficiency of above-mentioned aspect in existing product.
The purpose of this utility model is achieved through the following technical solutions:
A kind of shield receives with sealing steel bushing, the rear end cap being connected is fixed including the steel bushing body corresponding with shield machine and with this steel bushing body, described steel bushing body includes the some sleeve assemblies one being positioned at bottom and being sequentially connected with, before and after described sleeve assembly one, lateral symmetry connects sleeve assembly two, described sleeve assembly two has been fixedly connected with sleeve assembly three, and described sleeve assembly one, sleeve assembly two and sleeve assembly three collectively form a full circle, and described sleeve assembly three is evenly equipped with some injected holes.
Further, described steel bushing body is fixedly connected with transition connection ring away from one end of described rear end cap.
Further, described rear end cap is annular, and the inner ring of this rear end cap is fixedly connected with the end socket with circular arc.
Further, the angle of described sleeve assembly one is 180 degree.
Further, the quantity of described sleeve assembly one is 3.
Further, the angle of described sleeve assembly two and sleeve assembly three is 60 degree.
Further, the quantity of described sleeve assembly two is 2.
Further, described injected hole is positioned at the surface of steel bushing body.
The beneficial effects of the utility model are: be spliced by multiple assemblies, it is simple to manufacturing, production cost is low, removable during transport transports respectively, decreases the manpower and materials in transportation and cost of transportation.
