Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hardware products, and more specifically to a high-load-bearing hinge. Background Art
[0002] At present, the hinges for curtain wall windows on the market all include a window frame mounting strip, a window sash mounting strip and a connecting rod assembly. The connecting rod assembly includes at least an upper connecting rod and a lower connecting rod. During use, when the window sash is opened to the maximum, the central axis of the upper connecting rod forms an angle with the central axis of the window frame mounting strip. The angle is formed by the cooperation of a positioning column provided on the upper connecting rod and an arc-shaped hole provided on the window frame mounting strip. Such a structure is relatively complicated and requires a structure in which an arc-shaped hole is punched out on the window frame mounting strip, resulting in a high production cost.
[0003] As the market demand for products continues to increase, existing products are unable to adapt to today's tall and heavy windows. Tests have found that the hinges circulating on the market do not have high load-bearing properties and cannot be used on heavy windows for a long time.
[0004] Therefore, how to solve the problem that the hinge does not have high load-bearing capacity is an urgent problem to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of the utility model is to provide a high load-bearing hinge with a higher load-bearing capacity, which can significantly improve the load-bearing effect of the existing hinges compared to the existing hinges.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A high load-bearing hinge, comprising:
[0008] A window frame mounting member, wherein two ends of the window frame mounting member are respectively provided with a first hinge point and a second hinge point, and the first hinge point and the second hinge point are staggered with respect to a center line;
[0009] A window sash mounting member, wherein the window sash mounting member is provided with a third hinge point and a fourth hinge point;
[0010] A pull rod, one end of which is hinged to the first hinge point, and the other end of which is hinged to the third hinge point;
[0011] A connecting member, one end of the connecting member is hinged to the second hinge point, and the other end of the connecting member is hinged to the fourth hinge point;
[0012] When the window sash mounting member is unfolded, the third hinge point and the fourth hinge point are both located on the same side of the first hinge point and the second hinge point.
[0013] Preferably, a limiting rivet is provided on the window sash mounting member, and the limiting rivet is located between the third hinge point and the fourth hinge point.
[0014] Preferably, the limiting rivet is staggered with the third hinge point and the fourth hinge point about the midline, and the limiting rivet is arranged close to the window frame mounting piece.
[0015] Preferably, the first hinge point is arranged close to the window sash mounting member, and the second hinge point is arranged away from the window sash mounting member.
[0016] Preferably, the ratio of the distance between the third hinge point and the fourth hinge point to the distance between the fourth hinge point and the second hinge point is 1.1-1.2.
[0017] Preferably, the unfolding angle of the window sash mounting member is 60°-70°.
[0018] The high load-bearing hinge provided by the utility model includes a window frame mounting part, a window sash mounting part, a pull rod and a connecting part. Specifically, the two ends of the window frame mounting part are respectively provided with a first hinge point and a second hinge point, and the first hinge point and the second hinge point are staggered about the center line, so that when the hinge is in the folded state, the pull rod can overlap with the window frame mounting part as much as possible, thereby improving the space utilization rate.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.
[0031] The core of the utility model is to provide a high-load-bearing hinge. When the window sash mounting member 2 is unfolded, the third hinge point 21 and the fourth hinge point 22 are both located between the first hinge point 11 and the second hinge point 12. By increasing the length from the third hinge point 21 to the second hinge point 12 on the window sash mounting member 2, the overall load-bearing capacity of the hinge is improved.
[0032] Please refer to Figure 1 , Figure 2 and Figure 3 A high load-bearing hinge includes a window frame mounting component 1, a window sash mounting component 2, a pull rod 3 and a connecting component 4.
[0033] Specifically, a first hinge point 11 and a second hinge point 12 are correspondingly provided at both ends of the window frame mounting member 1. The first hinge point 11 and the second hinge point 12 are staggered about the center line so that when the hinge is in the folded state, the pull rod 3 can overlap with the window frame mounting member 1 as much as possible, thereby improving space utilization. A third hinge point 21 and a fourth hinge point 22 are provided on the window sash mounting part 2, one end of the pull rod 3 is hinged to the first hinge point 11, the other end of the pull rod 3 is hinged to the third hinge point 21, one end of the connecting member 4 is hinged to the second hinge point 12, and the other end of the connecting member 4 is hinged to the fourth hinge point 22. When the window sash mounting part 2 is unfolded, the window sash mounting part 2 and the connecting member 4 are distributed in a straight line. At this time, the corresponding vertical points of the third hinge point 21 and the fourth hinge point 22 on the window frame mounting part 1 are both located between the first hinge point 11 and the second hinge point 12, and the window frame mounting part 1, the pull rod 3, the window sash mounting part 2 and the connecting member 4 are distributed in a triangular shape to increase the bearing capacity of the hinge.
[0034] With the high load-bearing hinge arranged in the above manner, when the hinge is in the folded state, the second hinge point 12 is located between the third hinge point 21 and the fourth hinge point 22, and the bearing capacity of the hinge as a whole is improved by increasing the length from the third hinge point 21 to the fourth hinge point 22 on the window sash mounting member 2. When the window sash mounting member 2 is unfolded, the third hinge point 21 and the fourth hinge point 22 are both located on the same side of the first hinge point 11 and the second hinge point 12, and when the hinge is in the fully unfolded state, the window sash mounting member 2 and the connecting member 4 are in the same straight line, and the hinge as a whole is in a triangular shape to form a stable support structure, thereby being able to meet the long-term use requirements of heavy windows.
[0035] In the above embodiment, the window sash mounting member 2 is provided with a limiting rivet 5 , and the limiting rivet 5 is located between the third hinge point 21 and the fourth hinge point 22 .
[0036] It should be noted that the window sash mounting member 2 is also provided with a limiting rivet 5 for contacting with the pull rod 3 and the connecting member 4 to limit the window opening angle and the retraction angle.
[0037] In the above situation, the limiting rivet 5 is staggered with the third hinge point 21 and the fourth hinge point 22 about the center line, and the limiting rivet 5 is arranged close to the window frame mounting member 1 .
[0038] It can be understood that, when the hinge is in the open state, the limit rivet 5 contacts the pull rod 3, limiting the pull rod 3 from further rotation, thus forming a stable structure; in the folded state, the limit rivet 5 contacts the connecting piece 4, limiting the pull rod 3 from continuing to rotate clockwise.
[0039] Furthermore, the first hinge point 11 is arranged close to the window sash mounting member 2 , and the second hinge point 12 is arranged away from the window sash mounting member 2 .
[0040] It should be noted that the second hinge point 12 is arranged on the left side of the first hinge point 11, so that when the hinge is overlapped, the pull rod 3 can overlap with the window frame mounting component 1 as much as possible. At this time, the window sash opening is 0 degrees, and the window sash mounting component 2 and the window frame mounting component 1 reach the maximum overlap to improve space utilization.
[0041] On the basis of the above embodiment, the first hinge point 11 and the second hinge point 12 are used to install long rivets, and the third hinge point 21 and the fourth hinge point 22 are used to install short rivets. The upper end of the window frame mounting member 1 is hinged to the pull rod 3 through a long rivet to form the first hinge point 11, the lower end of the window frame mounting member 1 is hinged to the connecting member 4 through a long rivet to form the second hinge point 12, one end of the window sash mounting member 2 is hinged to the pull rod 3 through a short rivet to form the third hinge point 21, and the other end is hinged to the connecting member 4 through a short rivet to form the fourth hinge point 22.
[0042] Among them, in this embodiment, the first hinge point 11 and the second hinge point 12 are used to install long rivets, and the third hinge point 21 and the fourth hinge point 22 are used to install short rivets, but in actual life, there is no limitation to this as long as the above technical effects can be achieved.
[0043] On the basis of the above embodiment, the ratio of the distance between the third hinge point 21 and the fourth hinge point 22 to the distance between the fourth hinge point 22 and the second hinge point 12 is 1.1-1.2.
[0044] It can be understood that by increasing the length from the third hinge point 21 to the fourth hinge point 22 on the window sash mounting member 2, the bearing capacity of the entire hinge is improved.
[0045] As a preferred embodiment, the unfolding angle of the window sash mounting member 2 is 60°-70°.
[0046] It should be noted that, in the open state, the connecting member 4 and the window sash mounting member 2 are in a straight line, and the connecting member 4 and the window sash mounting member 2, the pull rod 3 and the window frame mounting member 1 are in a triangle. At this time, the unfolding angle of the window sash mounting member 2 is 70° (or about 70°).
[0047] In this embodiment, the unfolding angle of the window sash mounting member 2 is 60°-70°, but in actual life, there is no limitation to this as long as the above-mentioned technical effect can be achieved.
[0048] In summary, the high load-bearing hinge provided by the utility model has a second hinge point 12 between the third hinge point 21 and the fourth hinge point 22 when the hinge is in the folded state, and the length from the third hinge point 21 to the fourth hinge point 22 on the window sash mounting member 2 is increased to improve the overall load-bearing capacity of the hinge; when the hinge is unfolded to 70°, the limit rivet 5 reaches the limit, and the window sash mounting member 2 and the connecting member 4 are in the same straight line. At this time, the pull rod 3 and the window sash mounting member 2, the connecting member 4 and the window frame mounting member 1 are overall in a triangle, thereby forming a stable supporting structure in the unfolded state.
[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0050] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
