Specifically, the first elastic clamping assembly The component includes a first swing arm 24, one end of which is hinged on the first connecting arm 17, a bending portion 22 is extended on the lower connecting plate 16, the other end of the first swing arm 24 passes through a through slot 23 on the bending portion 22, a first step 25 is provided on the first swing arm 24, a first spring 32 is tightly provided between the first step 25 and the bending portion 22, and the lower connecting plate 16 is provided with a first limiting column 28 that can be abutted against the first connecting arm 17, so as to limit the swing position of the first connecting arm 17. The upper hinge body includes a second connecting arm 5, one end of which is hinged on the upper slide rail 7, and the other end of the second connecting arm 5 is hinged to the upper connecting plate 4. The upper connecting plate 4 is connected to the top of the window sash 2, and a second elastic clamping component is arranged corresponding to the second connecting arm 5. Specifically, the second elastic clamping component includes a second swing arm 12, one end of the second swing arm 12 is hinged on the second connecting arm 5, and a rotating block 8 is arranged on the upper connecting plate 4. The rotating block 8 is inserted into the second slot 10 on the second swing arm 12, and a second spring 11 is tightly arranged between the second swing arm 12 and the rotating block 8. A second limiting column 3 that can be abutted against the upper connecting plate 4 is arranged on the second connecting arm 5, so as to limit the swing angle of the second connecting arm 5, and a third limiting column 29 that can be inserted into the third slot 30 on the limiting plate 6 is arranged on the second connecting arm 5 to limit its left and right movement. A limit block 13 is provided on the second connecting arm 5, a limit plate 6 is provided on the window frame 1, a limit member 14 is movably provided on the limit plate 6, and a third elastic clamping assembly is provided in cooperation with the limit member 14. When the second connecting arm 5 swings to the window closing angle and moves, the limit member 14 and the limit block 13 are staggered and do not contact each other. When the second connecting arm 5 swings to the inverted angle, the limit member 14 can abut against the limit block 13. Further, a mounting groove is provided on the first connecting arm 17, and a roller seat 26 is embedded in the mounting groove. The roller seat 26 is provided with a roller 27 in contact with the lower connecting plate 16, so that the assembly method is simpler, and the gravity of the window sash 2 is pressed on the lower connecting plate 16 through the roller 27, so that the swing of the first connecting arm 17 is smoother. Furthermore, one end of the limit member 14 is rotatably set on the limit plate 6, and a limit groove 15 is set on the limit plate 6 for the limit member 14 to move. The third elastic clamping assembly includes a third spring 31, one end of the third spring is connected to the limit member 14, and the other end is connected to the limit plate 6, so that the limit member 14 is elastically pressed on one side of the limit groove 15, thereby realizing the elastic positioning of the limit member 14.In addition, in order to improve the stability and smoothness of the movement of the first and second connecting arms, plane bearings are provided at their hinges.
[0022] The working principle of the utility model is as follows: when the window sash needs to be controlled to open, the window sash 2 is pulled out in the direction away from the window frame 1, at which time the first connecting arm 17 of the first hinge body swings outward, and the positioning column 19 is separated from the first slot 20, and during the swinging process of the first connecting arm 17, the first swing arm 24 is driven to swing, and during the swinging process, the first spring 32 is compressed to the shortest state and then extends a certain length, so that the first spring 32 provides an elastic blocking force for the inward swinging of the first swing arm 24, thereby realizing the elastic positioning of the position of the first swing arm 24, and then realizing the elastic compression positioning of the position of the first connecting arm 17, and the first connecting arm 17 of the second hinge body is locked. The second connecting arm 5 will also swing outward, and drive the second swing arm 12 to swing. During the swinging process, the second spring 11 is compressed to the shortest state and then stretched to a certain length, so that the second spring 11 will provide an elastic blocking force for the inward swing of the second swing arm 12, thereby realizing the elastic positioning of the position of the second swing arm 12, and then realizing the positioning of the window sash 2 after opening; when it is necessary to control the window sash 2 to be closed, the window sash 2 is squeezed close to the window frame 1, the first connecting arm 17 of the first hinge body is retracted, and the positioning column 19 is just stuck in the first slot 20 of the first connecting arm 17, and the principle is the same as above, the first spring 32 provides the first swing arm 12 with an elastic blocking force. The arm 24 swings outward to provide an elastic blocking force, thereby realizing the elastic compression positioning of the first connecting arm 17, and the second connecting arm 5 of the second hinge body is also retracted. The principle is the same as above. The second spring 11 provides an elastic blocking force for the second swing arm 12 to swing outward, thereby realizing the elastic compression positioning of the second connecting arm 5, thereby realizing the positioning of the window sash 2 when it is retracted. When the window sash 2 is located at the side of the window frame 1, and it is necessary to control the top of the window sash 2 to tilt inward and open, so as to realize ventilation of a small area with the outside world, the window sash 2 is pulled to make the second connecting arm 5 of the second hinge body swing outward, thereby driving the top of the window sash 2 to tilt inward. At this time, the second connecting arm 5 The limit block 13 on the upper part is swung to a suitable angle, so that when the window sash 2 slides, the limit block 13 will abut against the limit member 14, thereby realizing the positioning of the window sash at the left and right positions. If the window sash 2 needs to be controlled to slide and open, a greater force is applied to make the limit block 13 squeeze the arc surface of the limit member 14 so that the limit member 14 swings, and the limit member 14 gives way. Then the limit block 13 is separated from the limit member 14, and the window sash 2 can slide without hindrance. The limit member 14 is reset by the torsion spring. At the same time, after the window sash is retracted and closed, the position of the limit block 13 is staggered with the limit member 14, and the sliding of the window sash 2 will not be hindered by the limit member 14.When the window sash 2 needs to be controlled to close, the window sash 2 slides to one side of the window frame 1, and the limit block 13 on the second connecting arm 5 first abuts against the limit member 14 to limit the movement of the window sash 2. Then, as the window sash 2 approaches the window frame 1, the second connecting arm 5 swings, so that the angle of the limit block 13 changes and is staggered and separated from the limit member 14. As the second connecting arm 5 swings to a fully retracted state, its first slot 20 is locked with the positioning column 19, thereby achieving that the window sash will not shake left and right when it is closed. ;
[0023] The structure of the utility model can realize elastic positioning when the window sash is tilted inward by improving the structure of the upper hinge body, thereby ensuring that the window sash will not move. By innovatively designing multiple groups of elastic clamping components, the hinge can realize elastic positioning when the sliding window is in an open or closed state, thereby ensuring the stability of the window sash position.
