Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1-8.

A hidden hinge hinge for casement windows of hidden frame curtain walls, which consists of a lower set 1 and an upper shaft 2, as shown in Figure 1. The lower set 1 is formed by connecting the lower fixing plate 101 and the lower bushing 102. As shown in FIG. The distance of the axis line of 102 is equal to the radius of the lower bushing 102, as shown in FIG. 3 . The lower fixing plate 101 is connected with the window sash material through a connecting piece, and the lower bushing 102 is used to insert the pivot 201 in the upper shaft member 2. In order to improve the wear resistance, it is better to install one in the lower bushing 102 as shown in Figure 4 In order to prevent the bushing 103 from rotating in the lower bushing 102, an anti-rotation raised strip 104 can be set on the bushing 103, and an anti-rotation raised strip 104 can be set in the lower bushing 102 accordingly groove, the upper end of the upper shaft sleeve can also be equipped with a cover, and the cover can be connected to the internal thread of the lower shaft sleeve 102 by external threads. The upper shaft member 2 is mainly composed of an upper fixed plate 202, an upper shaft sleeve 203 and a pivot 201. As shown in FIG. 5, the upper fixed plate 202 and the upper shaft sleeve 203 are eccentric structures, namely the upper fixed plate The distance between the positioning surface of 202 and the axis line of the upper sleeve 203 is equal to the radius of the upper sleeve 203 , as shown in FIG. 6 . The upper fixing plate 202 is integrally connected with the upper bushing 203, the pivot 201 is provided with a bearing plate 204, the upper end of the pivot 203 is inserted into the upper bushing 203, and the lower end of the pivot 201 is inserted into the lower kit 1, The pivot 201 is located on a section of the upper shaft sleeve 203 with a positioning groove 205 (as shown in Figure 7), and the upper shaft sleeve 203 is provided with a screw hole 206 for installing a positioning screw, and the positioning screw passes through The screw hole 206 is inserted into the positioning groove 205 to realize the axial positioning of the pivot 201 .
