Detailed Description

The utility model will be further described with reference to the accompanying drawings and specific embodiments so as to more clearly understand the technical idea of the utility model claimed.

The slide brace hinge shown in fig. 2-4 comprises a base 1, a short cantilever 2, an inclined cantilever 3, a long cantilever 4, a supporting arm 5, a positioning rapier head 6 and a positioning piece 7, wherein one end of the short cantilever 2, one end of the inclined cantilever 3 and one end of the long cantilever 4 are respectively hinged to the base 1, the other end of the short cantilever 2 is hinged to the long cantilever 4, the other end of the inclined cantilever 3 and the other end of the long cantilever 4 are respectively hinged to the supporting arm 5, the positioning rapier head 6 is installed at the bottom of the supporting arm 5, and the positioning piece 7 is installed at one end part of the base 1 and is connected with the positioning rapier head 6 in a positioning matching manner when the supporting arm 5 is folded and folded, namely, a window sash is closed.

Correspond short cantilever 2 in the bottom of base 1, oblique cantilever 3 is provided with cardboard 8 with base 1's articulated position, the middle part of cardboard 8 is provided with riveting hole 82, be located short cantilever 2 on the base 1, install between the cantilever 3 to one side and adjust rivet 10, it installs cardboard 8 rotatable regulation in base 1's bottom to adjust rivet 10 riveting in this riveting hole 82, it is equipped with elastic component 11 to lie in the cover between base 1 and cardboard 8 on the regulation rivet 10, if the sheet rubber, spring or elastic steel sheet etc., elastic component 11 both can make the draw-in groove space that forms the notch card wall with the window frame section bar between cardboard 8 and the base 1 and clamp, simultaneously can make cardboard 8 can compress elastic component 11 upwards promotes. The clamping plate 8 is a rectangular plate, the two ends of the clamping plate are symmetrically cut about the center of the riveting hole 82 to form inclined edges 80, and the two ends of the clamping plate 8 are respectively provided with a screw hole 81. The base 1 is provided with a screw through hole 90, and the screw hole 81 corresponds to the screw through hole 90 when the clamping plate 8 is rotatably adjusted to be parallel to the inclined edge 80 and the side edge of the base 1.

Before the clamping groove of the window frame section is installed, the adjusting rivet 10 is screwed to enable the straight edges 83 on the two sides of the clamping plate 8 to be parallel to the side edge of the base 1, the width between the straight edges 83 on the two sides of the clamping plate 8 is smaller than the width of a notch of the clamping groove of the window frame section, the clamping plate 8 can be installed into the clamping groove of the window frame section, then the adjusting rivet 10 is used for adjusting and rotating the clamping plate 8 to enable the inclined edge 80 to be parallel to the side edge of the base 1, at the moment, the inclined edge 80 rotates to the position below a notch clamping wall of the clamping groove of the window frame section, the lifting screw 9 penetrates through the screw through hole 90 to be connected with the screw hole 81, and the lifting screw 9 is screwed to enable the clamping plate 8 to be lifted upwards until the inclined edge 80 is tightly abutted to the bottom surface of the notch clamping wall of the clamping groove of the window frame section to complete the fastening and installation of the sliding support hinge on the window frame section. This kind of fastening mounting means, the contact surface of hypotenuse 80 and the notch chuckwall of window frame section bar draw-in groove is bigger, and the pulling and locking through lifting and pulling screw 9 are simultaneously firmly pressed from both sides the notch chuckwall of window frame section bar draw-in groove between hypotenuse 80 and the side of base 1, and it is more convenient and more firm relatively in the installation.

In addition, the arrangement position of the clamping plate 8 at the bottom of the base 1 corresponds to the hinged position of the short cantilever 2, the inclined cantilever 3 and the base 1, and the arrangement mode is favorable for improving the bearing capacity of the position of the short cantilever 2 and the inclined cantilever 3, so that the problem that the position is locally deformed due to weak structural strength of a hinge or locally deformed of the position of a window frame profile is avoided; of course, the card board 8 may be disposed at other positions on the bottom of the base 1 as required.
