In this embodiment, six hole sites are provided on the bottom plate 11, wherein three hole sites are located in the middle area, the other three hole sites are located in two end areas respectively, the hole sites in the middle area are used for riveting with the corresponding mounting holes of the first connecting rod 12, however, all three hole sites in the middle area are not required to be used in riveting, only one of the three hole sites in the middle area is required, so when one of the three hole sites in the middle area is used for riveting with the first connecting rod 12, the hole sites in the other two middle areas can be used for realizing fixation with the window frame 21, and the other two hole sites pass through the bottom plate 11 and the gasket 18 in sequence through the riveting piece 113 to be fixed with the window frame 21; if one of the end regions has two hole sites and the other end region has only one hole site, then one of the hole sites of the one end region is riveted with the mounting hole corresponding to the other end of the third connecting rod 14, the other hole site can also be used for fixing with the window frame 21 in the same manner as the other two hole sites in the middle, and the hole site of the other end region can also be used for fixing with the window frame, as will be described in more detail in the following embodiments.

In one embodiment, as shown in fig. 1, the fourth connecting rod 15 is rotatably connected to the pallet 16 near the middle.

In this embodiment, the supporting plate 16 is mounted on the window sash 22, specifically, by inserting the supporting plate 16 into the notch of the window sash 22 and fixing with screws, a length can be reserved at the position where the supporting plate 16 is connected to the fourth connecting rod 15 for facilitating the insertion of the supporting plate 16 into the notch, so that the other end of the fourth connecting rod 15 is preferably connected to the position near the middle of the supporting plate 16 in a rotating manner.

In one embodiment, the maximum angle of counterclockwise rotation of the first connecting rod 12 is flush with the bottom plate 11.

In this embodiment, during the operation of the hinge, the first connecting rod 12 rotates anticlockwise, drives the second connecting rod 13 to rotate clockwise, thereby driving the third connecting rod 14 to rotate anticlockwise, and drives the supporting plate 16 to rotate clockwise, and finally drives the fourth connecting rod 15 to rotate clockwise, so as to realize the opening and closing actions of the hinge. When the first connecting rod 12 rotates anticlockwise, the maximum rotating angle is flush with the bottom plate 11.

It should be noted that, when the hinge works, as shown by the rotating arrow in fig. 1, fig. 1 is a schematic structural diagram of the multi-link hinge with the window sash 22 in an open state, and if the first link 12 rotates counterclockwise around the first rotation point 131, the second link 13 is driven to rotate clockwise around the first rotation point 131, the third link 14 rotates counterclockwise around the third rotation point 141, the fourth link 15 rotates clockwise around the fourth rotation point 142 and the supporting plate 16 rotates clockwise around the second rotation point 132, so as to complete the closing action of the window sash 22; in the closed state, when the first connecting rod 12 rotates clockwise around the first rotation point 131, the second connecting rod 13 is driven to rotate anticlockwise around the first rotation point 131, the third connecting rod 14 rotates clockwise around the third rotation point 141, the fourth connecting rod 15 rotates anticlockwise around the fourth rotation point 142 and the supporting plate 16 rotates anticlockwise around the second rotation point 132, so that the opening action of the window sash 22 is completed, and the window sash 22 returns to the state of fig. 1. The hinge is provided with a full rotation point structure, each connecting rod is in a rotation connection mode, the hinge is simple in structure and stable in mechanical performance, and the connecting rods can be additionally arranged on the rotation points of the six connecting rods (comprising the bottom plate 11, the supporting plate 16 and the four connecting rods), so that stress of each connecting rod of the hinge is enhanced, the wind pressure resistance can be improved, the service life can be prolonged, particularly when the hinge is under the condition of resisting side wind pressure, the increased connecting rods assist the six connecting rods to bear stress, and the destructive power of the hinge is dispersed, so that the safety protection effect of the hinge is enhanced.

In an embodiment, the length of the first connecting rod 12 is smaller than the length of the second connecting rod 13, and the length of the second connecting rod 13 is smaller than the length of the third connecting rod 14.

In this embodiment, the lengths of the third connecting rod 14, the second connecting rod 13 and the first connecting rod 12 are sequentially reduced, through the lengths, the whole hinge design can accommodate 6 connecting rods, the rotation of the first connecting rod 12 can drive other connecting rods to rotate along the designed direction, the supporting plate 16 can finally move in the opposite direction to the first connecting rod 12, and the stress of the hinge can be enhanced to a greater extent through the structural design.

In one embodiment, the length of the third connecting rod 14 is greater than the length of the fourth connecting rod 15.

In this embodiment, by setting the length of the fourth connecting rod 15 shorter than the length of the third connecting rod 14, when the pallet 16 rotates clockwise, a transition effect is achieved by driving the fourth connecting rod 15 to rotate clockwise, so that the rotation force of the pallet 16 acts on the third connecting rod 14 rapidly, and the third connecting rod 14 is driven to rotate anticlockwise. If the length of the fourth connecting rod 15 is too long, the opening and closing actions of the whole hinge are not facilitated, and meanwhile, the acting force generated when the supporting plate 16 rotates cannot be rapidly acted on other connecting rods.

In one embodiment, the third link 14 rotates counterclockwise as the tray 16 rotates clockwise closed.

In this embodiment, when the supporting plate 16 is turned clockwise to be closed, the other connecting rods are also closed along a certain rotation direction, wherein the third connecting rod 14 rotates towards the inner side (i.e. anticlockwise), so that the whole hinge occupies smaller space when being opened and closed, and more profile requirements can be met.

As shown in fig. 2, the embodiment of the present invention also provides a window 2 including a window frame 21 and a window sash 22, the window frame 21 and the window sash 22 being connected by the multi-link hinge 1 of the previous embodiment.

In this embodiment, the multi-link hinge 1 is mounted between the window frame 21 and the window sash 22, in particular via the base plate 11 mounted on the window frame 21 and the carrier plate mounted on the window sash 22. The bottom plate 11 is fixed to the mounting groove of the window frame 21 by the locking plate 112, the supporting plate 16 is inserted into the notch of the window sash, and the supporting plate 16 is fixed by self-tapping screws. The window sash 22 is opened or closed along a certain trajectory by the action of a hinge for supporting the window sash 22 in the opened state of the window sash 22.

In an embodiment, as shown in fig. 3, the multi-link hinge 1 further includes a wrap angle 111, a locking plate 112, and a riveting member 113, where the wrap angle 111 is disposed at an end of the bottom plate 11, and the riveting member 113 sequentially passes through the wrap angle 111, the bottom plate 11, and is riveted to the window frame 21 with the locking plate 112.

In this embodiment, a positioning hole is provided on an end of the bottom plate 11, the wrap angle 111 is mounted on the bottom plate 11 through the positioning hole, the bottom plate 11, the lock plate 112 and the wrap angle 111 are riveted together through the rivet 113, and the lock plate 112 is rotated by rotating the rivet 113, so as to fix the multi-link hinge 1 on the window frame 21. The rivet 113 may be a hexagonal rivet, and the locking plate 112 may be a circular locking plate.

While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
