Embodiment 1

[0033] A friction hinge for a large outward-opening window, comprising a base plate 1 fixedly connected to the frame, a slider 3 slidably connected to the base plate 1, and a multi-link cantilever 2 rotatably connected to one end of the base plate 1. The connecting rod cantilever 2 slides on the bottom plate 1 by being rotationally connected with the slider 3 to realize opening and closing of the window sash.

[0034] The base plate 1 includes a first straight portion 101 fixed to the frame, a second straight portion 102 parallel to the first straight portion 101 and above the first straight portion 101, and a third flat portion 101. The straight portion 103, the first vertical portion 104 connecting the second straight portion 102 and the third straight portion 103 with the first straight portion 101 and parallel to the first vertical portion 104 and passing through The second vertical portion 105 connected to the second straight portion 102; the second straight portion 102 e...

Embodiment 2

[0040] A large outward-opening window friction hinge, which can be used for large or heavy outward-opening windows of high-rise buildings, includes a bottom plate 1 fixedly connected to the frame, a slider 3 slidingly connected in the bottom plate 1, and a rotatable joint connected to the bottom plate 1 is a multi-link cantilever 2 at one end, and the multi-link cantilever 2 slides on the bottom plate 1 by being rotationally connected with the slider 3 to realize the opening and closing of the window sash. The connection between the multi-link cantilever 2 and the slider 3 and the bottom plate 1 is not the same connection.

[0041] The bottom plate 1 is generally L-shaped, including a first straight portion 101 fixed to the frame, a second straight portion 101 parallel to the first straight portion 101 and above the first straight portion 101. part 102 and the third straight part 103, the first vertical part 104 connecting the second straight part 102 and the third straight pa...

Embodiment 3

[0047] A large outward-opening window friction hinge, which can be used for large or heavy outward-opening windows of high-rise buildings, includes a bottom plate 1 fixedly connected to the frame, a slider 3 slidingly connected in the bottom plate 1, and a rotatable joint connected to the bottom plate 1 is a multi-link cantilever 2 at one end, and the multi-link cantilever 2 slides on the bottom plate 1 by being rotationally connected with the slider 3 to realize the opening and closing of the window sash. The connection between the multi-link cantilever 2 and the slider 3 and the bottom plate 1 is not the same connection.

[0048] The bottom plate 1 has been designed to be widened and utilizes the principle of leverage to increase the length of the moment arm near the indoor side, so that in the case of a long moment arm and high load-bearing on the outdoor side, the stress at the short arm 201 will not be very large. extreme and lead to failure of the fastener or the short a...

Abstract

The present invention provides a friction hinge for a large outward opening window, comprising a bottom plate fixedly connected to a frame, a sliding block slidably connected in the bottom plate, and a multi-link cantilever rotatably connected to one end of the bottom plate. The rod cantilever is rotatably connected with the sliding block and slides on the bottom plate to realize the opening and closing of the window sash. By improving the structure of the bottom plate and the limiting gasket, the invention increases the vertical strength of the bottom plate, and also greatly enhances the lateral limiting ability of the multi-link cantilever under the limit angle. The concave-convex dual guide mechanism enhances the stability of the overall operation of the friction hinge under the action of repeated opening and closing for a long time. The sliding mechanism of the sliding rail and the sliding block arranged in the opposite direction on the bottom plate has long-term dustproof ability. At the same time, the sliding block adopts the combination of plastic-clad steel material structure to improve the wear resistance, and the force is more reasonable when the load is large.

Description

technical field [0001] The invention relates to the field of building doors and windows, in particular to a friction hinge for large outward opening windows. Background technique [0002] With the development of the door and window industry and people's demand for improving living standards, the size of the window sash is getting larger and larger. At the same time, the thickness of the glass is also increasing. Coupled with the application of three-layer glass and four-layer glass, the window sash is getting heavier and heavier. , which in turn brings higher and higher requirements for the load-bearing performance of the friction hinge, the load-bearing accessory of the window sash. [0003] The friction hinge is a connection device for building doors and windows with its own stress buffer. The upper and lower frames are stressed at the same time, the force type is good, and the torque is small; the friction hinge opens with a parabolic trajectory, which is convenient for w...
