Detailed Description

The invention is further explained below with reference to the drawings:

referring to fig. 1 and 2, a sliding support hinge includes a sliding rail 1, a sliding block 2, a supporting rod 3 and a sash fixing piece 4, a first hinge point 100 is disposed between one end of the supporting rod 3 and the sliding rail 1, a second hinge point 200 is disposed between the other end of the supporting rod 3 and the sash fixing piece 4, a third hinge point 300 is disposed between the other end of the sash fixing piece 4 and the sliding block 2, a length between the first hinge point 100 and the second hinge point 200 is L1, and a length between the second hinge point 200 and the third hinge point 300 is L2; when the sliding support hinge is vertically arranged at the top of the side edge of the window sash, the length of the L1 and the corresponding length of the L2 ensure that the vertical offset amplitude of the gravity center of the window sash is not more than 20mm in the opening process of the window sash from 0-30 degrees. It should be noted that the third hinge point 300 is an intersection point of the sash fixing piece 4 and the center line of the slider 2 when the opening angle of the sash is within 30 °; in practical application, the window sash fixing piece 4 and the sliding block 2 can be directly hinged or indirectly hinged. According to different window sash heights, the optimal corresponding values of L1 and L2 can be calculated in a drawing software simulation mode, multiple groups of corresponding values meeting conditions exist between L1 and L2, but due to the influences of factors such as the matching error of a sliding support hinge, the installation size error of the sliding support hinge and the window sash, L1 and L2 of an actual product may have a certain degree of error with a theoretical value simulated by software, and under the condition that the same technical effect can be achieved, the invention concept is the same as the invention concept.
