Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

As shown in fig. 1 to 5, a novel hinge for opening window comprises a bottom plate 1 for mounting on a window frame, a short rod 2 and a long rod 3 hinged with the bottom plate 1, and a support arm 4 hinged with the short rod 2 and the long rod 3, wherein after the hinge is completely opened, an outer side included angle a between the short rod 2 and the bottom plate 1 is an obtuse angle. Namely: after the hinge is completely opened, the hinge point of the short rod 2 and the support arm 4 is arranged between the hinge point of the short rod 2 and the base plate 1 and the hinge point of the long rod 3 and the base plate 1, the outer side included angle B of the short rod 2 and the support arm 4 is also an obtuse angle, and the hinge point of the short rod 2 and the base plate 1 is shortest from the window sash mounting end of the base plate 1. This further shortens the length of the short bar 2 and increases the load bearing of the hinge.

The preferred included angle A is 110-150 degrees, which ensures the window sash is tightly closed and the short rod 2 is shortest.

In the utility model, the hinge point of the short rod 2 and the bottom plate 1 does not slide, and the short rod 2 is provided with an adjusting piece 5 for adjusting the distance between the short rod 2 and the bottom plate 1. Preferably, the adjusting element 5 is an adjusting screw. The smooth degree of the rotation of the short rod 2 can be adjusted by rotating the adjusting piece 5. And, adjusting part 5 is located quarter butt 2 itself, adjusts its articulated elasticity more easily to, only have the screw on the bottom plate 1, do not have the spout mouth, even the live time is long, or in the big area of sand blown by the wind, also can not the laying dust too much, and influence quarter butt 2's rotation smooth degree.

Preferably, the short rod 2, the long rod 3 and the support arm 4 form a link mechanism of the hinge, so that the hinge structure is simplified, the short rod 2 can be made shorter, and the hinge can bear better load.

In a preferred embodiment of the present invention, a boss 6 is provided on the base plate 1, and a bent portion 31 matching with the boss 6 is provided at one end of the long rod 3 connected to the bracket arm 4. When the hinge is closed, the bending part 31 of the long rod 3 is arranged on the boss 6, so that the hinged end of the long rod 3 and the support arm 4 is supported, and the window sash is prevented from sagging. Preferably, a convex part 11 is arranged between the bottom plate 1 and the long rod 3 to strengthen the supporting force of the other end of the long rod 3 and further prevent the window sash from drooping; the bottom of the bending part 31 can be provided with a guide cambered surface 311, so that the bending part 31 can prevent the boss 6 from being damaged when the long rod 3 is closed. More preferably, the boss 6 has a limiting portion 61 matched with the side edge of the short rod 2, so as to prevent the window sash from being damaged by being opened excessively due to the fact that the short rod 2 is rotated excessively when being opened.

Further preferably, a connecting plate 7 is arranged between the short rod 2 and the bottom plate 1, and the connecting plate 7 covers the boss 6 and is matched with the bottom plate 1 and the boss 6, so that abrasion to the bottom plate 1 and the boss 6 is avoided.

In another embodiment, a limit piece 8 is arranged at the end of the bottom plate 1 close to the short rod, a guide piece 9 matched with the limit piece 8 is arranged at one end of the support arm 4 connected with the short rod, when the window sash is closed, the guide hinge is closed and returned, the excessive returning of the support arm 4 and the short rod 2 is limited, and the window sash is prevented from being opened reversely. Preferably, the limiting member 8 has a guiding inclined plane 81, the guiding member 9 is matched with the guiding inclined plane 81, and after the window sash closing hinge is folded, the guiding member 9 abuts against the guiding inclined plane 81 to prevent the hinge from being excessively restored. More preferably, the guiding inclined surface 81 is a cambered surface, and the guiding element 9 has a matching surface, so that the hinge can be folded or unfolded more smoothly in a homing way.
