Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a narrow-slot three-bar hinge. Background Technology

[0002] Most hinges on the market currently use a four-bar linkage structure. This structure cannot achieve large-stroke parallel opening. When encountering glass sashes thicker than 90mm, they can only open to 70 to 80 degrees, which is not aesthetically pleasing. Especially when encountering narrow-edged floor-to-ceiling screen windows, there is also the problem of screen sash sagging. Moreover, the hinge stroke is mostly around 50mm, and the C-groove screen sash is wider, requiring more space, increasing costs and affecting the overall effect. Furthermore, narrow-edged four-bar hinges are generally prone to tipping over, have poor stability, and insufficient load-bearing capacity. Utility Model Content

[0003] This utility model discloses a solution to address the shortcomings of the prior art.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A narrow-slot three-bar hinge includes a frame base plate, a connecting rod, and a sash fixing plate. Both the frame base plate and the sash fixing plate are L-shaped structures. The long side of the L-shape of the frame base plate has a first mounting hole and a second mounting hole. The second mounting hole is located between the first mounting hole and the edge of the frame base plate. A support plate is fixedly mounted on the sash fixing plate. The support plate has a first mounting hole and a second mounting hole at each end, with a third mounting hole between them. The connecting rod has a Z-shaped structure, with a first mounting hole at each end. The fan mounting plate has a first mounting hole and a second mounting hole. The first mounting hole of the base plate and the first mounting hole of the connecting rod are connected together by round rivets. The second mounting holes of the support plate, the second mounting holes of the connecting rod and the second mounting holes of the mounting plate are connected together by round rivets. The first mounting hole of the mounting plate and the third mounting hole of the support plate are fixed together by round rivets. The second mounting hole of the base plate and the first mounting hole of the support plate are connected together by round rivets. The base plate, the support plate, the connecting rod and the fan mounting plate form a three-bar linkage structure.

[0006] The second mounting hole on the base plate is a strip-shaped hole. When the first mounting hole of the support plate is located at different positions in the strip-shaped hole of the second mounting hole on the base plate, the included angle between the base plate and the fan fixing plate will be different. Specifically, when the distance between the first mounting hole of the base plate and the first mounting hole of the support plate is the smallest, the included angle between the base plate and the fan fixing plate is 90 degrees. When the distance between the first mounting hole of the base plate and the first mounting hole of the support plate is the largest, the included angle between the base plate and the fan fixing plate is 0 degrees.

[0007] The base plate and the sash fixing plate are provided with at least two screw fixing holes on the long side of the L-shape and one screw fixing hole on the short side of the L-shape. The screw fixing holes are fixed to the rotating clip by hexagonal rivets and washers. The rotating clip is set in the T-shaped groove of the window sash profile.

[0008] The rotating clamp is provided with a hexagonal hole, and the hexagonal head of the hexagonal rivet is located in this hexagonal hole. The rotating clamp can rotate as the hexagonal rivet rotates.

[0009] The mounting location of the screw fixing hole is provided with a protrusion. When the clamping plate rotates, it can contact the protrusion to limit the continued rotation of the clamping plate.

[0010] The beneficial effects of this utility model are: the window sash can be opened from 0 to 90 degrees through the hinge, and it can be opened flexibly and reliably in parallel with the glass sash. The structure is reasonable, the force is balanced, and it solves the problem of the floor-standing screen sash sagging. It is beautiful and practical. Attached Figure Description

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. In order to make the purpose, technical solution and advantages of this utility model clearer, the technical solution of this utility model will be described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of this utility model.

[0016] See appendix Figure 1-3This utility model includes a frame base plate 1, a connecting rod 3, and a fan fixing plate 4. Both the frame base plate 1 and the fan fixing plate 4 are L-shaped structures. The long side of the L-shape of the frame base plate 1 is provided with a first mounting hole 11 and a second mounting hole 12. The second mounting hole 12 is located between the first mounting hole 11 and the frame base plate 1 and its edge 13. A support plate 2 is fixedly installed on the fan fixing plate 4. The two ends of the support plate 2 are respectively provided with a first mounting hole 21 and a second mounting hole 22, and a third mounting hole 23 is provided between them. The connecting rod 3 is a Z-shaped structure, with a first mounting hole 31 and a second mounting hole 32 at each end. The rod has a second mounting hole 32, and the fan fixing plate 4 has a first mounting hole 41 and a second mounting hole 42. The base plate has a first mounting hole 11 and the connecting rod has a first mounting hole 31 connected together by a round rivet 6. The support plate has a second mounting hole 22, the connecting rod has a second mounting hole 32 and the fixing plate has a second mounting hole 42 connected together by a round rivet 6. The fixing plate has a first mounting hole 41 and the support plate has a third mounting hole 23 fixed together by a round rivet 6. The base plate has a second mounting hole 12 and the support plate has a first mounting hole 21 connected together by a round rivet 6. The base plate 1, the support plate 2, the connecting rod 3 and the fan fixing plate 4 form a three-bar linkage structure.

[0017] The second mounting hole 12 of the base plate is a strip-shaped hole. When the first mounting hole 21 of the support plate is located at different positions in the strip-shaped hole of the second mounting hole 12 of the base plate, the included angle between the base plate 1 and the fan fixing plate 4 is different. Specifically, when the distance between the first mounting hole 11 of the base plate and the first mounting hole 21 of the support plate is the smallest, the included angle between the base plate 1 and the fan fixing plate 4 is 90 degrees. When the distance between the first mounting hole 11 of the base plate and the first mounting hole 21 of the support plate is the largest, the included angle between the base plate 1 and the fan fixing plate 4 is 0 degrees.

[0018] The base plate 1 and the sash fixing plate 4 are provided with at least two screw fixing holes 7 on the long side of the L-shape and one screw fixing hole 7 on the short side of the L-shape. The screw fixing holes 7 are fixed to the rotating clip 5 by hexagonal rivets 9 and washers 8. The rotating clip 5 is set in the T-shaped groove of the window sash profile.

[0019] The rotating clamp 5 is provided with a hexagonal hole, and the hexagonal head of the hexagonal rivet 9 is located in this hexagonal hole 91. The rotating clamp 5 can rotate with the rotation of the hexagonal rivet 9.

[0020] The mounting location of the screw fixing hole 7 is provided with a protrusion 71. When the screw clip 5 rotates, it can contact the protrusion 71 to limit the screw clip 5 from continuing to rotate.

[0021] In practical applications, the window sash profile is provided with a T-slot. When installing the hinge, the clip 5 is installed in this T-slot. At this time, the hexagonal rivet 9 is rotated to make the clip 5 lock into the T-slot, thus enabling the hinge to be quickly installed on the window sash profile. The second mounting hole 12 of the base plate is a strip hole. When the first mounting hole 21 of the support plate is located in different positions in the strip hole of the second mounting hole 12 of the base plate, the included angle between the base plate 1 and the sash fixing plate 4 is different. Among them, when the first mounting hole 11 of the base plate and the support plate 21 are located in different positions in the strip hole of the second mounting hole 12 of the base plate, the included angle between the base plate 1 and the sash fixing plate 4 is different. When the distance between the first mounting holes 21 of the support plate is at its minimum, the angle between the base plate 1 and the sash fixing plate 4 is 90 degrees. When the distance between the first mounting holes 11 of the base plate and the first mounting holes 21 of the support plate is at its maximum, the angle between the base plate 1 and the sash fixing plate 4 is 0 degrees, thus realizing the opening and closing of the window sash. Since the hinge is a three-bar structure, the structure is stable and reliable, with very little swaying during movement. It opens flexibly and reliably parallel to the glass sash, with a reasonable structure and balanced force distribution. It solves the problem of sagging of the floor-standing screen sash, making it both beautiful and practical.
