Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to an externally hinged, sealed, adjustable hinge. Background Technology

[0002] Casement windows use sealing strips to seal the sash and frame. The sash and frame are connected by hinges to open and close the window. The two ends of the hinge are fixed to the frame and the sash respectively. The opening and closing path is achieved through the hinge linkage. Turning the handle moves the transmission mechanism inside the sash, which moves the lock seat. The lock seat engages with the locking points on the frame to open and close the sash.

[0003] However, the limiting mechanism between the window sash and the window frame of a casement window results in a low degree of tightness, which can lead to poor fit of the sealing strip, resulting in poor window sealing or severe pressure on the sealing strip. Utility Model Content

[0004] The purpose of this invention is to provide an externally hinged, sealed, and adjustable hinge to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides an outward-opening, sealed, adjustable hinge, comprising a window frame connector, a window sash connector, a first connecting arm, a second connecting arm, and a third connecting arm. The window frame connector is movably connected to the window sash connector via the first, second, and third connecting arms. The window frame connector has a slidable sliding member. The two ends of the first connecting arm are rotatably connected to the window sash connector and the sliding member, respectively. The two ends of the second connecting arm are rotatably connected to the window sash connector and the window frame connector, respectively. One end of the third connecting arm is rotatably connected to the window sash connector, and the other end is rotatably connected to the middle of the first connecting arm. The window frame connector is rotatably connected to a corner bracket with a guide position. The window sash connector has a guide protrusion for extending into the guide position. A corner bracket base plate is vertically connected to the bottom of the corner bracket. The corner bracket base plate is fixed to one end of the window frame connector by a first screw. Two limiting grooves are symmetrically opened on both sides of the corner bracket base plate. The window frame connector is provided with a first limiting block corresponding to the limiting grooves and used to limit the rotation of the corner bracket.

[0006] Optionally, the window frame connector is provided with a guide groove, and the sliding member includes a first slider, a guide part and a second slider connected in sequence. The first slider and the second slider are respectively slidably engaged on opposite sides of the window frame connector, and the guide part is guided and engaged in the guide groove.

[0007] Optionally, one end of the first connecting arm is rotatably connected to the sliding member by a first rivet, and the other end is rotatably connected to the window sash connector by a second rivet. The side of the first connecting arm near the window frame connector slides in contact with the side of the sliding member.

[0008] Optionally, one end of the second connecting arm is rotatably connected to the window frame connector using a third rivet, and the other end is rotatably connected to the window sash connector using a fourth rivet.

[0009] Optionally, one end of the third connecting arm is rotatably connected to the window frame connector by a fifth rivet, and the other end is rotatably connected to the first connecting arm by a sixth rivet, wherein the fifth rivet is located between the first rivet and the third rivet.

[0010] Optionally, the window frame connector is provided with a connecting plate that is rotatably connected to the second connecting arm and the third connecting arm respectively, and the connecting plate is installed on the window frame connector with a second screw. A second limiting block for limiting the rotation of the second connecting arm and the third connecting arm is provided on the connecting plate between the second connecting arm and the third connecting arm.

[0011] Optionally, the corner protector and the corner protector base plate are integrated. The corner protector includes a straight edge, a beveled edge, and an arc edge between the beveled edge and the straight edge, wherein the beveled edge is located on the side of the window sash connector that moves outward.

[0012] Optionally, the window sash connector is provided with a mounting block perpendicular to the window sash connector at one end near the second connecting arm. The mounting block has a through hole extending along the length of the window sash connector, and a clamping member is rotatably inserted into the through hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The corner base plate of this utility model is fixed to one end of the window frame connector by the first screw, so that the corner connected to the corner base plate is adjustable. The corner can rotate around the first screw at a certain angle, so that its guide position is adjusted so that the guide convex angle can be inserted. Moreover, a translation gap is reserved between the guide convex angle and the guide position, so that after the guide convex angle enters the guide position of the corner, the guide convex angle is no longer restricted by the corner. Thus, when the window sash connector and the window frame connector are parallel or basically parallel, the window sash can be translated into the window frame, improving the tightness between the window sash and the window frame. The end of the window sash near the hinge will not prematurely squeeze the sealing strip near the hinge with the window frame, thereby reducing the speed at which the sealing strip near the hinge is squeezed and aged, and extending the service life of the sealing strip.

[0023] like Figures 1-3As shown, this utility model embodiment provides an outward-opening, sealed, adjustable hinge, including a window frame connector 1, a window sash connector 2, a first connecting arm 3, a second connecting arm 4, and a third connecting arm 5. The window frame connector 1 is movably connected to the window sash connector 2 via the first connecting arm 3, the second connecting arm 4, and the third connecting arm 5. The window frame connector 1 is provided with a slidable sliding member 6. The two ends of the first connecting arm 3 are rotatably connected to the window sash connector 2 and the sliding member 6, respectively. The two ends of the second connecting arm 4 are rotatably connected to the window sash connector 2 and the window frame connector 1, respectively. The third connecting arm... One end of the hinge 5 is rotatably connected to the window sash connector 2, and the other end is rotatably connected to the middle of the first connecting arm 3. Specifically, this hinge is used to connect the window frame and the window sash of a casement window. The window frame connector 1 is installed in the window frame, and the window sash connector 2 is installed in the window sash. Through the coordinated operation of the window frame connector 1, the window sash connector 2, the first connecting arm 3, the second connecting arm 4, and the third connecting arm 5, the window sash can be opened or closed relative to the window frame. The window sash connector 2 is provided with a guide protrusion 8 for extending into a guide position. Specifically, the guide protrusion 8 is provided with a guide connection part. The guide connection is bolted or riveted to the window sash connector 2 to install the guide protrusion 8, or it can be stamped onto the window sash connector 2 to integrally form the guide protrusion 8 onto the window sash connector 4. The window frame connector 1 is rotatably connected to the corner 7 with a guide position. The guide position is larger than the guide protrusion 8. When the guide protrusion 8 extends into the guide position and the window sash connector 2 is parallel or basically flush with the window frame connector 1, the side of the guide protrusion 8 is completely separated from the working surface of the guide position, allowing the window sash to slide in and out of the window frame. The corner 7 has a reserved translation gap; the bottom of the corner 7 is vertically connected to the corner base plate 9, the corner base plate 9 is fixed to one end of the window frame connector 1 by the first screw 10, the corner base plate 9 has two symmetrical limiting grooves 11 on both sides, the window frame connector 1 is provided with a first limiting block 12 corresponding to the limiting groove 11 and used to limit the rotation of the corner 7, the corner 7 and the corner base plate 9 are integrated, the corner 7 includes a straight edge 701, a bevel 702 and an arc edge 703 between the bevel 702 and the straight edge 701, wherein the bevel 702 is provided on the side of the window sash connector 2 in the outward movement direction;Specifically, when the guide position of the corner bracket 7 does not match the guide convex angle 8, rotating the screw 10 causes the corner bracket base plate 9 to no longer be fixed to the window frame connector 1. At this time, the corner bracket base plate 9 can rotate around the screw 10. Under the limiting action of the first limiting block 12 on the limiting groove 11, the corner bracket 7 rotates around the screw 10 by a certain angle, following the rotation of the corner bracket base plate 9, so that its guide position matches the guide convex angle 8. That is, the guide convex angle 8 can extend into the guide position. A translation gap is reserved between the guide convex angle 8 and the guide position, so that after the guide convex angle 8 enters the guide position of the corner bracket 7, the guide convex angle 8 is no longer restricted by the corner bracket 7. In this way, when the window sash connector 2 and the window frame connector 1 are parallel or basically parallel, the window sash can be translated into the window frame, and the end of the window sash near the hinge will not prematurely press against the sealing strip near the hinge with the window frame.

[0024] In this embodiment, as Figure 1 As shown, the window frame connector 1 is provided with a guide groove 13, and the sliding member 6 includes a first slider 601, a guide part 602 and a second slider 603 connected in sequence. The first slider 601 and the second slider 603 are respectively slidably engaged on opposite sides of the window frame connector 1, and the guide part 602 is guided and engaged in the guide groove 13.

[0025] Specifically, through the guiding cooperation of the guide part 602 and the guide groove 13, the sliding member can extend along the length direction of the guide groove.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, one end of the first connecting arm 3 is rotatably connected to the sliding member 6 by the first rivet 14, and the other end is rotatably connected to the window sash connector 2 by the second rivet 15. The side of the first connecting arm 3 near the window frame connector 1 is in sliding contact with the side of the sliding member 6.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, one end of the second connecting arm 4 is rotatably connected to the window frame connector 1 by the third rivet 16, and the other end is rotatably connected to the window sash connector 2 by the fourth rivet 17.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, one end of the third connecting arm 5 is rotatably connected to the window frame connector 1 by the fifth rivet 18, and the other end is rotatably connected to the first connecting arm 3 by the sixth rivet 19. The fifth rivet 18 is located between the first rivet 14 and the third rivet 16.

[0029] In this embodiment, as Figure 1 and Figure 2As shown, the window frame connector 1 is provided with a connecting plate 20 that is rotatably connected to the second connecting arm 4 and the third connecting arm 5 respectively, and the connecting plate 20 is installed on the window frame connector 1 with a second screw 22. A second limiting block 21 for limiting the rotation of the second connecting arm 4 and the third connecting arm 5 is provided on the connecting plate 20 between the second connecting arm 4 and the third connecting arm 5.

[0030] Specifically, the second limiting block 21 on the connecting plate 20 is used to limit the maximum opening angle between the second connecting arm 4 and the third connecting arm 5, thereby improving the wind pressure resistance of the hinge, preventing the window sash from falling off, and reducing safety hazards.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, a mounting block 23 perpendicular to the window sash connector 2 is provided at one end near the second connecting arm 4. A through hole is provided on the mounting block 23, which extends along the length of the window sash connector 2. A clamping member 24 is inserted into the through hole. After the clamping member 24 is rotated to a preset angle, it can be clamped at the window sash groove.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
