Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the utility model.
The application provides a threaded connection end frame, specifically makes and to form support and interlinkage according to threaded connection, and manufacturing process is simple, a structure that can mass production, structure, design, manufacturing, installation simple process is favorable to promoting in a large number.
Fig. 2 is a schematic view of a threaded connection end frame provided in the present application. Comprises an upper section frame and a lower section frame, wherein the upper section frame is connected with the lower section frame through a screw thread.
Wherein the diameters of the upper frame and the lower frame are the same.
Preferably, the material of the upper section frame and the lower section frame is stainless steel.
Specifically, the upper frame includes an upper frame end face 1, and an upper frame end thread 2. The lower frame comprises a lower frame end face 3 and a lower frame end thread 4.
The upper section frame end thread 2 is positioned at the inner side of the upper section frame, and the lower section frame end face 3 and the lower section frame end thread 4 are poured into a whole to form the lower section frame.
As shown in fig. 3, which is a detailed view of the threads in the threaded connection end frame, the height of the lower frame end thread 4 is the same as the height of the upper frame end thread 2. So that the upper section frame end thread 2 positioned at the inner side of the upper section frame can be just in seamless threaded connection with the lower section frame end thread 4.
