Description

Technical Field

[0001] This utility model relates to the technical field of hardware door and window profiles, and in particular to a load-bearing curtain wall profile window support hinge. Background Technology

[0002] With the rapid development of modern building technology, load-bearing curtain wall systems are increasingly widely used in high-rise buildings. As an important component of the curtain wall system, the supporting structure of profile windows directly affects the safety and performance of the entire building. Especially in high-rise buildings and extreme weather conditions, the supporting hinges of curtain wall windows not only need to withstand conventional static loads but also need to resist dynamic loads such as wind pressure and earthquakes. Current curtain wall window supporting hinges mainly adopt a cantilever structure design, whose working principle is to achieve the opening and closing of the window sash through single-axis or multi-axis rotation. However, this structure has many technical defects in practical applications:

[0003] First, the structure struggles to effectively distribute horizontal, vertical, and torque forces. Under dynamic loads such as strong winds or earthquakes, localized areas of the hinges are prone to overload, and stress concentration can easily occur at the connection points, leading to connection failure and affecting the overall structural stability.

[0004] Secondly, the adjustment mechanism of this structure mostly uses a simple bolt fastening method, which makes the adjustment process cumbersome and prone to loosening under vibration, resulting in a decrease in the positioning accuracy of the window sash. Utility Model Content

[0005] To overcome the technical problems of stress concentration, poor positioning accuracy, and lack of balanced transmission of multi-directional forces in existing technologies under harsh environments, this utility model provides a load-bearing curtain wall profile window support hinge, comprising: a base plate assembly, which includes a base plate and a first positioning structure, the first positioning structure being mounted on the base plate; a hinge assembly, the hinge assembly having an initial position and a maximum angle position relative to the base plate assembly, the hinge assembly having a movable node, the hinge assembly including a first hinge member and a second hinge member, the movable node connecting the first hinge member and the second hinge member; the first hinge member having a first hinge end, the first hinge... The first hinge member is rotatably connected to the base plate; the second hinge member has a second hinge end, which is rotatably connected to the base plate; the straight line connecting the rotation center of the first hinge end and the rotation center of the second hinge end forms the horizontal axis of the base plate; the movable node deviates from the horizontal axis, and the first positioning structure positions the first hinge member, the second hinge member, and the base plate at the maximum angle position, forming a rigid triangular structure; the first hinge member, the second hinge member, and the movable node are collinearly arranged, and the hinge assembly is located in the initial position.

[0006] Furthermore, the base plate assembly also includes a first rivet and a second rivet, the first rivet and the second rivet are mounted on the base plate, the first hinge end is hinged to the base plate by the first rivet; the second hinge end is hinged to the base plate by the second rivet.

[0007] Furthermore, the first positioning structure is located on the horizontal axis and is close to the second hinge end; the second hinge includes a second hinge rod with a rotating side; when the movable node deviates from the horizontal axis, the rotating side abuts against the first positioning structure.

[0008] Furthermore, the second hinge member also includes a positioning piece, one end of the second hinge rod is the second hinge end, and the end of the second hinge rod away from the second hinge end is rotatably connected to the positioning piece; the first hinge member has a first limiting edge; the positioning piece has a positioning limiting edge; when the movable node deviates from the horizontal axis, the positioning limiting edge abuts against the first limiting edge.

[0009] Furthermore, the second hinge also includes a second connecting rod and a plurality of fourth rivets; the second connecting rod portion covers the positioning plate and is rotatably connected to the positioning plate via the fourth rivets.

[0010] Furthermore, the first hinge member includes a first hinge rod and a first connecting rod; one end of the first hinge rod is the first hinge end, and a fixed point is located near the first hinge end; one end of the first connecting rod is rotatably connected to the fixed point.

[0011] Furthermore, it also includes a slider and a third rivet; the slider has a second rivet hole; the base plate has a sliding groove; the other end of the first connecting rod has a first rivet hole; the third rivet passes through the first rivet hole, the second rivet hole and the sliding groove in sequence to achieve a sliding connection.

[0012] Furthermore, the second connecting rod has a rotating hole A located at the top of its outer edge near the portion covering the positioning piece; the end of the first hinge rod away from the first hinge end has a rotating hole B; the fourth rivet passes through the rotating hole A and the rotating hole B in sequence to form the movable node.

[0013] Furthermore, the rotating side is designed with a rounded transition.

[0014] Furthermore, it also has a positioning shaft, which is fixedly mounted on the base plate. The axis of the positioning shaft is parallel to the horizontal axis, and the axis of the positioning shaft has an eccentric distance in a direction perpendicular to the horizontal axis. The positioning piece also has a groove, and the positioning shaft is located in the concave surface of the groove. Beneficial effects

[0015] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0016] The hinge assembly has an initial position and a maximum angular position relative to the base plate through a movable node. The movable node is movably connected to the first hinge member and the second hinge member. Since the first hinge end of the first hinge member is rotatably connected to the base plate and the second hinge end of the second hinge member is rotatably connected to the base plate, the line connecting the rotation center line of the first hinge end and the rotation center line of the second hinge end almost overlaps with the horizontal axis on the base plate.

[0017] When the hinge assembly is in its initial position, the first hinge rotates towards the side closer to the second hinge, and the second hinge rotates towards the side farther from the first hinge, until the first hinge, the second hinge, and the movable node are collinear. The rotation center lines of the first hinge end, the second hinge end, and the movable node are all on the horizontal axis of the base plate, meaning the hinge assembly covers and is housed on the base plate. When the hinge assembly is in its maximum angle position, the second hinge rotates towards the side closer to the first hinge, and the first hinge rotates towards the side farther from the second hinge. When one side rotates, the first positioning structure connects with the hinge assembly, positioning the first hinge, the second hinge, and the base plate at the maximum angle position. The first hinge, the second hinge, and the base plate form a rigid triangular structure. The first and second hinges can balance the loads on both sides of the base plate, prevent stress concentration on one side, and improve shear or torsional resistance. Especially in harsh environments, stress is evenly distributed on the edges of the rigid triangular structure (referring to the first hinge, the second hinge, and the base plate), avoiding the technical defects of existing technologies, such as stress concentration in the hinge, which easily leads to failure of the connection node and poor positioning accuracy.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 6 A load-bearing curtain wall profile window support hinge includes: a base plate assembly 1, which includes a base plate 13 and a first positioning structure 14, the first positioning structure 14 being mounted on the base plate 13; a hinge assembly 2, the hinge assembly 2 having an initial position and a maximum angle position relative to the base plate assembly 1, the hinge assembly 2 having a movable node 201, the hinge assembly 2 including a first hinge member 21 and a second hinge member 22, the movable node 201 connecting the first hinge member 21 and the second hinge member 22; the first hinge member 21 having a first hinge end 2111, the first hinge end 2111 being rotatably connected to the base plate 13; the second hinge member 22 having a second hinge end 221. 1. The second hinge end 2211 is rotatably connected to the base plate 13; the straight line connecting the rotation center of the first hinge end 2111 and the rotation center of the second hinge end 2211 forms the horizontal axis 130 of the base plate 13; the movable node 201 is offset from the horizontal axis 130, and the first positioning structure 14 positions the first hinge member 21, the second hinge member 22 and the base plate 13 at the maximum angle position, and the first hinge member 21, the second hinge member 22 and the base plate 13 form a rigid triangular structure; the first hinge member 21, the second hinge member 22 and the movable node 201 are arranged collinearly, and the hinge assembly 2 is located in the initial position.

[0029] It should be noted that a “connecting straight line” is defined as a straight line connecting the rotation center of the first hinge end 2111 to the rotation center of the second hinge end 2211, with the two points forming a line.

[0030] In this technical solution, the hinge assembly 2 has an initial position and a maximum angle position relative to the base plate 13 through the movable node 201. The movable node 201 is movably connected to the first hinge member 21 and the second hinge member 22. Since the first hinge end 2111 of the first hinge member 21 is rotatably connected to the base plate 13 and the second hinge end 2211 of the second hinge member 22 is rotatably connected to the base plate 13, the straight line connecting the rotation center of the first hinge end 2111 and the rotation center of the second hinge end 2211 forms the horizontal axis 130 of the base plate 13.

[0031] When the hinge assembly 2 is in its initial position, the first hinge 21 rotates towards the side closer to the second hinge 22, and the second hinge 22 rotates away from the first hinge 21, until the first hinge 21, the second hinge 22, and the movable node 201 are collinearly aligned. The rotation center lines of the first hinge end 2111, the second hinge end 2211, and the movable node 201 are all on the horizontal axis 130 of the base plate 13, meaning the hinge assembly 2 covers and is housed on the base plate 13. When the hinge assembly 2 is in its maximum angle position, the second hinge 22 rotates towards the side closer to the first hinge 21, and the first hinge 22 rotates away from the first hinge 21, until the first hinge 21, the second hinge 22, and the movable node 201 are collinearly aligned. Rotating away from the side of the second hinge 22, the first positioning structure 14 connects with the hinge assembly 2, positioning the first hinge 21, the second hinge 22, and the base plate 13 at the maximum angle position. The first hinge 21, the second hinge 22, and the base plate 13 form a rigid triangular structure. The first hinge 21 and the second hinge 22 can balance the load on both sides of the base plate 13, prevent stress concentration on one side, and improve the shear or torsional resistance. Especially in harsh environments, the stress is evenly distributed on the edge of the rigid triangular structure (referring to the first hinge 21, the second hinge 22, and the base plate 13), avoiding the technical defects of the prior art, such as stress concentration in the hinge, which easily leads to failure of the connection node and poor positioning accuracy.

[0032] Depend on Figure 2 , Figure 5 and Figure 6 As shown, the base plate assembly 1 further includes a first rivet 11 and a second rivet 12, the first rivet 11 and the second rivet 12 are mounted on the base plate 13, the first hinge end 2111 is hinged to the base plate 13 through the first rivet 11; the second hinge end 2211 is hinged to the base plate 13 through the second rivet 12.

[0033] In this technical solution, two mounting holes are pre-set on the base plate 13, and the coaxiality of the two mounting holes is ensured. The first hinge end 2111 is hinged to one of the mounting holes of the base plate 13 through the first rivet 11, and the second hinge end 2211 is hinged to the other mounting hole of the base plate 13 through the second rivet 12. The rotation of the first hinge member 21 and the second hinge member 22 is stable. The first rivet 11 and the second rivet 12 can share the friction between the first hinge member 21, the second hinge member 22 and the base plate 13 during rotation. The first rivet 11 and the second rivet 12 are on the horizontal axis 130 and jointly bear the force of the first hinge end 2111 and the second hinge end 2211, avoiding the concentration of stress at a single point. The first rivet 11 and the second rivet 12 are not easy to misalign, and the first hinge end 2111 and the second hinge end 2211 are not easy to misalign, resulting in a stable structure.

[0034] The specific implementation of the first positioning structure 14 and the second hinge member 22 is as follows: Figures 2 to 4 As shown, the first positioning structure 14 is located on the horizontal axis 130 and is close to the second hinge end 2211; the second hinge member 22 includes a second hinge rod 221, which has a rotating side 2210; when the movable node 201 deviates from the horizontal axis 130, the rotating side 2210 abuts against the first positioning structure 14.

[0035] In this technical solution, the first positioning structure 14 is a mounting post, vertically fixed on the base plate 13 and located on the horizontal axis 130, that is, between the first hinge end 2111 and the second hinge end 2211. The first positioning structure 14 is close to the second hinge end 2211 of the second hinge member 22, and the second hinge rod 221 of the second hinge member 22 has a rotating side 2210. When the second hinge member 22 rotates towards the side closer to the first hinge member 21 until the hinge assembly 2 is at its maximum angle position, the rotating side 2210 abuts against the first positioning structure 14. Preferably, the rotating side 2210 is provided with an arc transition, which solves the problem of the second rivet 12 tilting due to the sudden abutment of the first positioning structure 14, and provides a buffer.

[0036] At this point, the specific implementation methods of the second hinge member 22 and the first hinge member 21 are as follows: Figure 3 and Figure 4 As shown, the second hinge member 22 further includes a positioning piece 222, one end of the second hinge rod 221 is the second hinge end 2211, and the end of the second hinge rod 221 away from the second hinge end 2211 is rotatably connected to the positioning piece 222; the first hinge member 21 has a first limiting edge 2113; the positioning piece 222 has a positioning limiting edge 2221; when the movable node 201 deviates from the horizontal axis 130, the positioning limiting edge 2221 abuts against the first limiting edge 2113.

[0037] In this technical solution, one end of the second hinge rod 221 of the second hinge member 21 is the second hinge end 2211, and the other end of the second hinge rod 2211 is rotatably connected to the positioning piece 222 by a rivet. When the second hinge member 22 rotates toward the side closer to the first hinge member 21 until the hinge assembly 2 is at its maximum angle position, the rotating side 2210 abuts against the first positioning structure 14, and the second hinge rod 221 pushes the positioning piece 222 to rotate. The positioning limiting edge 2221 of the positioning piece 222 abuts against the first limiting edge 2113 of the first hinge member 21. At this time, the angle between the second hinge rod 221 and the side of the positioning piece 222 and the side of the positioning piece 222 and the side of the second hinge rod 221 is approximately 45 degrees. By the positioning limiting edge 2221 abutting against the first limiting edge 2113, the second hinge member 22 is rigidly prevented from continuing to rotate toward the side closer to the first hinge member 21.

[0038] When the hinge assembly 2 is in its initial position, the second hinge 22 rotates away from the first hinge 21. The positioning plate 222 rotates in the opposite direction to the second hinge rod 221. The positioning limiting edge 2221 separates from the first limiting edge 2113, allowing the first hinge 21 to rotate towards the side closer to the second hinge 22. This continues until the first hinge 21, the second hinge 22, and the movable node 201 are collinear. The rotation center lines of the first hinge end 2111, the second hinge end 2211, and the movable node 201 are all on the horizontal axis 130 of the base plate 13. In other words, the hinge assembly 2 covers and is housed on the base plate 13, preventing overload of the first hinge end 2111, the second hinge end 2211, and the movable node 201. This disperses concentrated stress and avoids the technical defects of the prior art, such as stress concentration in the hinge, which can easily lead to connection node failure and poor positioning accuracy.

[0039] Furthermore, a specific embodiment of the second hinge 22 is provided by Figures 2 to 4 As shown, the second hinge 22 also includes a second connecting rod 223 and a plurality of fourth rivets 224; the second connecting rod 223 partially covers the positioning piece 222 and is rotatably connected to the positioning piece 222 through the fourth rivets 224.

[0040] In this embodiment, the second connecting rod 223 forms a rotatable structure with the positioning piece 222 through the fourth rivet 224. When the hinge assembly 2 is in the maximum angle position, the rotating side 2210 abuts against the first positioning structure 14, and the second hinge rod 221 pushes the positioning piece 222 to rotate. Under vibration, the second connecting rod 223 can quickly drive the positioning limiting edge 2221 of the positioning piece 222 to rotate, so that the positioning limiting edge 2221 of the positioning piece 222 can quickly abut against the first limiting edge 2113 of the first hinge member 21. This ensures that when the hinge assembly 2 is in the maximum angle position, it still maintains a rigid triangular structure with the base plate 13, resulting in a stable structure and accurate positioning.

[0041] A specific embodiment of the first hinge member 21 is described below. Figure 2 and Figure 3 As shown, the first hinge member 21 includes a first hinge rod 211 and a first connecting rod 212; one end of the first hinge rod 211 is the first hinge end 2111, and a fixed point 2110 is located near the first hinge end 2111; one end of the first connecting rod 212 is rotatably connected to the fixed point 2110.

[0042] In this technical solution, one end of the first hinge rod 211 is the first hinge end 2111, and a fixed point 2110 is provided near the first hinge end 2111 for connecting the first connecting rod 212. The first connecting rod 212 is used to cooperate with the rotation of the first hinge rod 211, to distribute the force on the first hinge rod 211 and reduce the generation of torque. At the same time, the first connecting rod 212 supports the rotation of the first hinge rod 211.

[0043] Specifically, by Figure 2 As shown, it also includes a slider 3 and a third rivet 4; the slider 3 has a second rivet hole 31; the base plate 13 has a sliding groove 132; the other end of the first connecting rod 212 has a first rivet hole 2121; the third rivet 4 passes through the first rivet hole 2121, the second rivet hole 31 and the sliding groove 132 in sequence to achieve a sliding connection.

[0044] In this technical solution, the connection structure between the sliding groove 132 and the first connecting rod 212 is simple. The slider 3 is simply inserted into the sliding groove 132, the first rivet hole 2121 of the first connecting rod 212 is aligned with the second rivet hole 31 of the slider 3, and then connected sequentially using the third rivet 4. The connection is convenient. When the first hinge 21 rotates, the first connecting rod 212 drives the slider 3 to slide in the sliding groove 132. This, combined with the rigid triangular structure, enables the opening and closing of the support hinge, thereby opening and closing the window sash and helping to distribute the stress of the support hinge. To ensure a better fit between the slider 3 and the sliding groove 132, the slider 3 can be connected to an adjusting screw to adjust the tightness between the slider 3 and the sliding groove 132, allowing the slider 3 to slide smoothly.

[0045] It is worth noting that the specific implementation method of activity node 201 is determined by... Figures 2 to 4 As shown, the second connecting rod 223 has a rotating hole A2231 located at the top of its outer edge near the portion covering the positioning piece 222; the first hinge rod 211 has a rotating hole B2112 at one end away from the first hinge end 2111; the fourth rivet 224 passes through the rotating hole A2231 and the rotating hole B2112 in sequence to form the movable node 201.

[0046] In this technical solution, the second connecting rod 223 is divided into two parts. One part is covered on the positioning piece 222, and the other part has a rotating hole A2231. The rotating hole A2231 is close to the positioning piece 222. The end of the first hinge rod 211 away from the first hinge end 2111 has a rotating hole B2112. The end of the first hinge rod 211 away from the first hinge end 2111 is superimposed on the first connecting rod 223 with the rotating hole A2231. The rotating hole A2231 and the rotating hole B2112 correspond to each other and are connected by rivets. The first hinge rod 211 and the second connecting rod 223 are hinged together to form the movable node 201. The window sash can be closed and opened by the movable node 201 being in the initial position and the maximum angle position.

[0047] Depend on Figure 1 As shown, it also has a positioning shaft 5, which is fixedly installed on the base plate 13. The axis of the positioning shaft 5 is parallel to the horizontal axis 130, and the axis of the positioning shaft 5 has an eccentric distance in the direction perpendicular to the horizontal axis 130. The positioning piece 222 also has a groove 2220, and the positioning shaft 5 is located in the concave surface of the groove 2220.

[0048] In this technical solution, the axis of the positioning shaft 5 is parallel to the horizontal axis 130 and has an eccentric distance in the direction perpendicular to the horizontal axis 130. When the window sash is closed, the supporting hinge is in the initial position and the hinge assembly 2 is stored on the base plate 13. At this time, the positioning piece 222 is also collinear with the horizontal axis 130, and the groove 2220 of the positioning piece 222 can just accommodate the positioning shaft 5. Under the action of strong wind or vibration, it can prevent the hinge assembly 2 from opening again, ensuring the tightness of the supporting hinge when it is in the initial position and improving the sealing of the window.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
