DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-12The embodiment of the present invention provides a technical solution: a casement window load-bearing hinge assembly, including a connecting hinge 30, the connecting hinge 30 includes a window frame connecting frame 1 and a window sash connecting frame 4, wherein the window frame connecting frame 1 is used to be fixedly connected to the window frame, and the window sash connecting frame 4 is used to be fixedly connected to the window sash, a slide rail 11 is provided on the window frame connecting frame 1 and a slide seat 2 is slidably installed, the window frame connecting frame 1 is provided with a slide rail 11 along its length direction, and the slide seat 2 is slidably set in the slide rail 11, a first connecting arm 5 is rotatably connected between the window frame connecting frame 1 and the window sash connecting frame 4, one end of the first connecting arm 5 is rotatably connected to the window frame connecting frame 1, and the other end of the first connecting arm 5 is rotatably connected to the window sash connecting frame 4, the slide seat 2 and the window sash connecting frame 4 are rotatably connected with a second connecting arm 3, and the second connecting arm One end of the second connecting arm 3 is rotatably connected to the slide 2, the other end of the second connecting arm 3 is rotatably connected to the window sash connecting frame 4, and the slide 2 is also rotatably connected to the third connecting arm 51, and the other end of the third connecting arm 51 is rotatably connected to the first connecting arm 5, that is, the window frame is opened and closed by sliding the slide 2 on the slide rail 11 and rotating the first connecting arm 5, the second connecting arm 3 and the third connecting arm 51. The slide rail 11 is provided with adjusting teeth 12 at the head and tail ends of the movement stroke of the slide 2; a plurality of friction buffer assemblies 6 are symmetrically and movably provided on both sides of the slide 2. When the slide 2 slides on the slide rail 11 to the head or tail end of its movement stroke, the adjusting teeth 12 drive the plurality of friction buffer assemblies 6 to protrude in sequence to increase the friction between the slide 2 and the slide rail 11 to buffer and decelerate the slide 2. That is, when the window sash is at the end of its opening stroke and the end of its closing stroke, the adjusting teeth 12 on the slide rail 11 drive the multiple friction buffer components 6 to protrude in sequence, and the multiple friction buffer components 6 protrude in sequence to increase the friction resistance between the slide 2 and the slide rail 11, thereby achieving deceleration and buffering of the slide 2, that is, achieving deceleration and buffering of the window sash at the end of its opening stroke and closing stroke.

[0037] This embodiment provides a bearing hinge assembly for a casement window. By providing an adjustment tooth portion 12 on a slide rail 11 and a plurality of friction buffer assemblies 6 on a slide 2, when the window sash is at the end of its opening stroke and the end of its closing stroke, the adjustment tooth portion 12 on the slide rail 11 sequentially drives the plurality of friction buffer assemblies 6 to protrude. The plurality of friction buffer assemblies 6 gradually increase the friction resistance between the slide 2 and the slide rail 11, thereby achieving deceleration and buffering of the slide 2, i.e., achieving deceleration and buffering of the window sash at the end of its opening stroke and the end of its closing stroke, thereby preventing the door sash from colliding with the door frame due to external wind, causing deformation of the door frame or the door sash, and affecting the sealing of the door sash and the door frame after closing. Furthermore, the bearing hinge assembly is prevented from deforming and affecting the opening and closing operation of the door sash. Furthermore, during the buffering and deceleration, the plurality of friction buffer assemblies 6 sequentially protrude to increase the friction resistance between the slide 2 and the slide rail 11, achieving smooth transition and buffering deceleration, preventing a sudden increase in friction resistance and damage to the connecting hinge 30 due to inertia, thereby extending the service life of the connecting hinge 30.

[0038] In another embodiment provided by the present invention, the friction buffer assembly 6 includes a friction portion 61 and an adjustment member 62. The adjustment member 62 is rotatably mounted on the slide 2 and meshes with the adjustment tooth portion 12. The friction portion 61 is movably mounted on the side of the slide 2, and the adjustment member 62 is used to drive the friction portion 61 to slide and adjust. The friction portion 61 includes a notch 611 provided on the side of the slide 2. The notch 611 is slidably connected to an abutment seat 612 via a tension spring 615. A rubber block 614 is fixed to the outside of the abutment seat 612. The adjustment member 62 includes an adjustment gear 621. The adjustment gear 621 rotates on the side of the slide 2 and is connected to an adjustment cam 622 via a connecting shaft. The adjustment cam 622 is rotatably mounted in the notch 611 and corresponds to the abutment seat 612. The adjustment gear 621 meshes with the adjustment tooth portion 12 for transmission, and the adjustment gear 621 is driven by the adjustment tooth portion 12 to rotate 180 degrees. Specifically, when the window sash is being adjusted for opening and closing, the slide 2 slides back and forth on the slide rail 11. When the slide 2 slides on the slide rail 11 to the beginning or end of its movement stroke, that is, when the window sash is at the end of the opening stroke or the closing stroke, the adjusting tooth portion 12 on the slide rail 11 meshes with the adjusting gear 621 on the adjusting member 62 and drives the adjusting gear 621 to rotate 180°. At this time, the adjusting gear 621 drives the adjusting cam 622 to rotate 180° through the connecting shaft. At this time, the convex portion of the adjusting cam 622 abuts against the abutment seat 612, thereby driving the abutment seat 612 and the rubber block 614 thereon to protrude to the outside of the slot 611 and abut against the inner wall of the slide rail 11, thereby increasing the friction force of the slide 2 sliding on the slide rail 11. At the same time, when the slide 2 continues to move, the adjusting tooth portion 12 on the slide rail 11 drives the adjusting gear 621 to rotate 180° in sequence. The rubber blocks 614 in the multiple friction buffer assemblies 6 protrude and abut against the inner wall of the slide rail 11, thereby gradually increasing the friction resistance between the slide seat 2 and the slide rail 11, achieving smooth transition and buffering deceleration, preventing the friction resistance from suddenly increasing, and causing damage to the connecting hinge 30 due to inertia, thereby extending the service life of the connecting hinge 30. When the slide seat 2 moves from the slide rail 11 from the beginning or end of its movement stroke, similarly, the adjustment tooth portion 12 on the slide rail 11 drives the adjustment cams 622 on the multiple adjustment members 62 to rotate and reset, that is, the adjustment cam 622 is separated from the abutment seat 612. At this time, under the action of the tension spring 615, the abutment seat 612 drives the rubber block 614 thereon to slide and retract to the slot 611 to reset, thereby reducing the friction resistance of the slide seat 2 on the slide rail 11, making it easier to adjust the door leaf.

[0039] In another embodiment provided by the present invention, an arcuate notch 613 is formed on the abutment seat 612 to match the adjustment cam 622. By forming the arcuate notch 613 on the abutment seat 612 to match the adjustment cam 622, when the protrusion of the adjustment cam 622 abuts against the abutment seat 612, the adjustment cam 622 abuts in the arcuate notch 613. When the adjustment tooth portion 12 on the slide rail 11 is separated from the adjustment member 62, the rotation of the adjustment cam 622 needs to overcome the resistance of the abutment of the arcuate notch 613, thereby improving the stability of the support provided by the adjustment cam 622.

[0040] In another embodiment provided by the present invention, the window sash connecting frame 4 is an L-shaped structure, and the horizontal end of the window sash connecting frame 4 is spirally connected with a plurality of first connecting studs 42, the vertical end of the window sash connecting frame 4 is spirally connected with a second connecting stud 41, and the first connecting stud 42 is cross-connected with the second connecting stud 41, and the second connecting stud 41 is equidistantly provided with a plurality of first connecting screw holes 411, and the plurality of first connecting studs 42 are spirally connected in each first connecting screw hole 411. By setting the window sash connecting frame 4 as an L-shaped structure, a clamping installation is achieved when installing the window sash connecting frame 4, and the vertical area end of the window sash connecting frame 4 located in the L-shaped structure is connected to the second connecting stud 41 and embedded in the inner side of the window sash profile. At the same time, multiple first connecting studs 42 connected on the horizontal section of the window sash connecting frame 4 located in the L-shaped structure are connected to the first connecting screw holes 411 on the second connecting stud 41, thereby reducing the force on the window sash profile, preventing the window sash profile from being deformed by the force of the second connecting stud 41 when the window sash is opened and closed, affecting the sealing of the window sash profile after closing, and at the same time improving the stability of the connection between the window sash connecting frame 4 and the window sash, preventing it from falling off.

[0041] In another embodiment provided by the present invention, the window sash connecting frame 4 is an L-shaped structure, and the horizontal end of the window sash connecting frame 4 is spirally connected with a plurality of first connecting studs 42, the vertical end of the window sash connecting frame 4 is spirally connected with a second connecting stud 41, and the first connecting stud 42 is cross-connected with the second connecting stud 41, and the plurality of first connecting studs 42 are provided with second connecting screw holes 421, and the second connecting stud 41 is connected to the second connecting screw holes 421 on the plurality of first connecting studs 42.

[0042] By setting the window sash connecting frame 4 as an L-shaped structure, a clamping installation is achieved when installing the window sash connecting frame 4, and the vertical area end of the window sash connecting frame 4 located in the L-shaped structure is connected to the second connecting stud 41 and embedded in the inner side of the window sash profile. At the same time, the horizontal section of the window sash connecting frame 4 located in the L-shaped structure is connected with the first connecting stud 42 and the second connecting stud 41 is connected to the second connecting screw hole 421, thereby reducing the force on the window sash profile, preventing the window sash profile from being deformed by the force of the second connecting stud 41 when the window sash is opened and closed, affecting the sealing of the window sash profile after closing, and at the same time improving the stability of the connection between the window sash connecting frame 4 and the window sash, preventing it from falling off.

[0043] In another embodiment provided by the present invention, preferably, a sheath mechanism 7 is symmetrically provided at both ends of the slide 2, and the sheath mechanism 7 is used to cover the slide rail 11. The slide rail 11 is also provided with a driving tooth portion 13, and the driving tooth portion 13 is transmission-connected to the sheath mechanism 7, and the driving tooth portion 13 is used to retract and adjust the sheath mechanism 7, so that when the slide 2 is slid and adjusted, the sheath mechanism 7 and the opening on the slide rail 11 are adaptively adjusted and covered.

[0044] The driving teeth 13 are symmetrically arranged on both sides of the open bottom of the slide rail 11. The sheath mechanism 7 includes a rotating shaft 71, which is rotatably arranged at the bottom of both ends of the slide 2, and a covering belt 72 is rotatably wound on the rotating shaft 71. One end of the covering belt 72 passes through the top of the slide 2 and is connected to the open end of the slide rail 11. Gear sleeves 73 are fixed at both ends of the rotating shaft 71, and the gear sleeves 73 are engaged with the driving teeth 13.

[0045] When the slide 2 slides on the slide rail 11, the driving tooth portion 13 drives the rotating shaft 71 at one end of the slide 2 to rotate and unwind, and at the same time, the driving tooth portion 13 drives the rotating shaft 71 at the other end of the slide 2 to rotate and rewind, so that the unwinding of the rotating shaft 71 on one side covers the opening of the slide rail 11 through the covering belt 72, thereby preventing dust and impurities from entering the slide rail 11 and affecting the normal sliding of the slide 2, and the rotating shaft 71 on the other side rotates and rewinds to cooperate with the slide 2 to slide and avoid, thereby not affecting the normal sliding adjustment of the slide 2.

[0046] Furthermore, a dust box 74 is detachably embedded on the inner side of the two sheath mechanisms 7 on the slide 2, and a dust collection opening 741 is opened on the side of the dust box 74 relative to the rotating shaft 71, so that when the rotating shaft 71 is reeling in the covering belt 72, the dust particles on the covering belt 72 can automatically fall into the dust box 74 through the dust collection opening 741 and be collected, thereby facilitating cleaning by the staff.

[0047] A casement window includes the aforementioned connecting hinge 30, a window sash 20, and a window frame 10.
