Description

Technical Field

[0001] This utility model relates to the technical field of hinges, and in particular to a wind-resistant hinge for casement windows. Background Technology

[0002] Casement windows are a common type of window, named for their horizontal movement when opened and closed. Hinges, installed on opposite sides of the window sash and connected to the window frame, are key components supporting the window sash and ensuring its flexible opening. Referring to the utility model patent CN211173601U, entitled "A Heavy-Duty Outward-Opening Window Sliding Hinge," conventional window sliding hinges typically consist of a track, a first rod, a second rod, a third rod, and a support arm. The first and second rods are hinged to sliders, which slide along the track. To ensure wind resistance, the third rod is rotatably connected to the track. When the hinge moves, the first and second rods slide along the track, while the third rod rotates within it. Furthermore, the first and second rods are positioned on one side of the track, while the third rod is on the other, providing the main stress point. Therefore, the uneven force distribution on both sides of the track during movement reduces the smoothness of the hinge's movement and reduces its wind resistance. Utility Model Content

[0003] The present invention provides a wind-resistant hinge for casement windows to solve the aforementioned problems and improve the smoothness and wind resistance of the hinge.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant hinge for a casement window, comprising a sliding plate, a first connecting rod, a second connecting rod, and a third connecting rod. The first and second connecting rods are each hinged to a slider a, which is slidably connected to the sliding plate. The third connecting rod is hinged to a slider b, which is slidably connected to the sliding plate. A fourth connecting rod is provided between the slider a and the slider b, with one end hinged to the middle of the sliding plate and the other end hinged to the third connecting rod. Both slider a and slider b abut against the hinge point between the fourth connecting rod and the sliding plate.

[0005] Furthermore, the slide plate includes a flat plate portion and a J-shaped inner groove portion, and a protrusion is provided on one side of the a slider and the b slider, and the protrusion is correspondingly disposed in the inner groove portion.

[0006] Furthermore, one side of the flat plate is provided with a through groove, and the third connecting rod and the b slider are connected by a connecting rod. One end of the connecting rod passes through the through groove and is slidably connected to the through groove.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As shown in the attached diagram, this utility model discloses a wind-resistant hinge for a casement window, comprising a sliding plate 1, a first connecting rod 11, a second connecting rod 12, and a third connecting rod 13. This is an existing structure. The first connecting rod 11, the second connecting rod 12, and the third connecting rod 13 are arranged along the length of the sliding plate 1. The existing hinge structure also includes a support arm 2. One end of the third connecting rod 13 is hinged to the middle of the support arm 2. One end of the first connecting rod 11 is hinged to the side of the third connecting rod 13 near the support arm 2. One end of the second connecting rod 12 is hinged to one end of the support arm 2. Both the first connecting rod 11 and the second connecting rod 12 are hinged to sliders a 101, which are slidably connected to the sliding plate 1. The third connecting rod 13 is hinged to slider b 102. The b slider 102 is slidably connected to the slide plate 1. A fourth connecting rod 14 is provided between the a slider 101 and the b slider 102. One end of the fourth connecting rod 14 is hinged to the middle of the slide plate 1, and the other end is hinged to the third connecting rod 13. When the hinge is unfolded, the a slider 101 and the b slider 102 gradually move closer to the fourth connecting rod 14 until the hinge is unfolded to the maximum angle. At this point, the a slider 101 and the b slider 102 both abut against the hinge of the fourth connecting rod 14 and the slide plate 1. The first connecting rod 11 and the second connecting rod 12 are set on one side of the slide plate 1 through the a slider 101, the third connecting rod 13 is set on the other side of the slide plate 1 through the b slider 102, and the fourth connecting rod 14 is hinged to the middle of the slide plate 1.

[0020] This utility model discloses a wind-resistant hinge for a casement window. A first link 11 and a second link 12 are disposed on one side of a sliding plate 1, and a third link 13 is disposed on the other side of the sliding plate 1. The first link 11, the second link 12, and the third link 13 slide on the sliding plate 1 via slider a 101 and slider b 102, respectively, so as to achieve balanced left and right sliding during hinge movement, thereby improving the smoothness of hinge movement. Furthermore, a fourth link 14 is added in the middle of the sliding plate 1, and the other end of the fourth link 14 is hinged to the third link 13 to provide support for the third link 13. The fourth link 14, which is hinged in the middle of the sliding plate 1, improves the overall support and enhances the overall wind resistance of the hinge.

[0021] Specifically, the slide plate 1 includes a flat plate portion 15 and a J-shaped inner groove portion 16. A protrusion 1011 is provided on one side of the a slider 101 and the b slider 102. The protrusion 1011 is correspondingly disposed in the inner groove portion 16. The slide plate 1 is integrally formed by the flat plate portion 15 and the inner groove portion 16. The protrusion 1011 of the a slider 101 and the b slider 102 are slidably engaged by the inner groove portion 16 to prevent the a slider 101 and the b slider 102 from falling off the slide plate 1. Each connecting rod is extended or retracted from the side of the flat plate portion 15 away from the inner groove portion 16. The flat plate 15 has a through groove 100 on one side. The third connecting rod 13 and the b slider 102 are connected by a connecting rod 1021. One end of the connecting rod 1021 passes through the through groove 100 and is slidably connected to the through groove 100. The through groove 100 passes through the flat plate 15 vertically. The connecting rod 1021 passes through the third connecting rod 13 and the b slider 102 from top to bottom, and extends through the through groove 100 to the lower side of the flat plate 15. It is then fixed by connecting parts such as nuts. The diameter of the connecting rod 1021 corresponds to the width of the through groove 100 to ensure that the b slider 102 slides linearly on the slide plate 1. The connecting rod 1021 can be made of existing parts such as rivets. In addition, the first connecting rod 11, the second connecting rod 12 and the fourth connecting rod 14 are all hinged by the connecting rod 1021.

[0022] Specifically, the fourth connecting rod 14 is provided with an anti-collision member 141 for abutting against slider a 101 and slider b 102. The anti-collision member 141 includes a gasket 1411 and an abutment strip 1412. The gasket 1411 is disposed between the fourth connecting rod 14 and the slide plate 1, and the abutment strip 1412 is disposed within the inner groove 16. The anti-collision member 141 is preferably made of plastic, and the shape of the anti-collision member 141 is as follows: Figure 6 As shown, the anti-collision component 141 mainly prevents slider a 101 and slider b 102 from directly colliding with the hinge of the fourth link 14, thus providing protection. The gasket 1411 has a through hole, and the connecting rod 1021 is sequentially inserted through the fourth link 14, the through hole, and the flat plate 15. The connecting rod 1021 connects the various parts together. The anti-collision component 141 is in the shape of a "flag", that is, the gasket 1411 is set on one side of the abutment strip 1412. When the hinge is extended to the maximum angle, slider a 101 will abut against one side of the gasket 1411 and the abutment strip 1412, and slider b 102 will abut against the other side of the abutment strip 1412.

[0023] Specifically, the bottom of the slide plate 1 is provided with a reinforcing plate 151 with the same width as the groove of the profile. The reinforcing plate 151 is connected to the fourth connecting rod 14. As those familiar with hinge installation know, the hinge needs to be installed on the groove of the profile. The reinforcing plate 151 is set on this basis. The width of the reinforcing plate 151 corresponds to the width of the groove to ensure that the hinge will not sag and further improve the wind resistance and load-bearing capacity of the hinge.

[0024] Specifically, both slider a 101 and slider b 102 include an outer plastic layer and an inner metal plate. The outer plastic layer contacts the slide plate 1 and abuts against the anti-collision member 141 to prevent direct metal-to-metal contact. The inner metal plate is mainly to ensure the strength of slider a 101 and slider b 102. The outer plastic layer can be directly wrapped around the inner metal plate, or a groove can be provided on the upper side of the outer plastic layer and the inner metal plate can be placed in the groove.

[0025] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
