[0032] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0034] Combine Figure 1-3 As shown, an embodiment of the present invention provides a high load-bearing hinge, which is connected to a first target installation object 1 and a second target installation object 2 of a door or window, and includes a lower hinge assembly 3 and a load-bearing assembly 4. The lower hinge assembly 3 is connected below between the first target installation object 1 and the second target installation object 2, and one end of the load-bearing assembly 4 is arranged on the first target installation object 1, and the other end is arranged on the lower hinge assembly 3.

[0035] In an embodiment of the present invention, the lower hinge assembly 3 is connected below the first target installation object 1 and the second target installation object 2. When the door and window are opened, the lower hinge assembly 3 opens, and the lower hinge assembly 3 located below the second target installation object 2 bears the load. By setting the load-bearing assembly 4, the load-bearing capacity of the hidden hinge structure of the door and window when the door and window are opened is increased. At the same time, the load-bearing assembly 4 and the lower hinge assembly 3 are integrated into one, which reduces costs, simplifies the installation process, and improves production efficiency.

[0036] Furthermore, the load-bearing assembly 4 includes a mounting member (not shown), a first connecting member 42, and a rotating member 43. The mounting member is disposed on the first target installation object 1, and the rotating member 43 is disposed on the lower hinge assembly 3. One end of the first connecting member 42 is connected to the mounting member, and the other end is connected to the rotating member 43. Specifically, the mounting member is an adjustment member 41, which can adjust the tension of the first connecting member 42.

[0037] In this embodiment, a first connecting member 42 is used to connect the rotating member 43 and the adjusting component 41. The adjusting component 41 is set on the first target installation object 1 and does not move as the second target installation object 2 moves away. The adjusting component 41 is used to adjust the tension of the first connecting member 42. That is, when load-bearing is required, the first connecting member 42 can be adjusted to be tight, thereby replacing the lower hinge component 3 to share part of the weight from the second target installation object 2, thereby increasing the load-bearing capacity of the high-load-bearing hinge when the doors and windows are opened horizontally, which can effectively prevent the doors and windows from falling off.

[0038] Combine Figure 3-5 As shown, the adjustment component 41 includes a first fixing member 411, an adjusting member 412 and a sliding member 413. The first fixing member 411 is arranged on the first target installation object 1. The first fixing member 411 is provided with a first adjustment hole 4111 and a second adjustment hole 4112 that are in communication with each other. The adjusting member 412 is connected below the first adjustment hole 4111. The sliding member 413 includes a first sliding portion 4131 and a second sliding portion 4132 that can be slidably arranged in the first adjustment hole 4111 and the second adjustment hole 4112 respectively, and the first sliding portion 4131 is abutted against the adjusting member 412, and the second sliding portion 4132 is connected to the first connecting member 42.

[0039] In this embodiment, controlling the movement of the adjusting member 412 can control the movement of the first sliding portion 4131 that is against the adjusting member 412. The second sliding portion 4132 and the first sliding portion 4131 are connected side by side. The second sliding portion 4132 can drive the first connecting member 42 connected to the second sliding portion 4132 to move, thereby adjusting the tension of the first connecting member 42.

[0040] Specifically, as the adjusting member 412 moves upward, the first connecting member 42 becomes tighter, and as the adjusting member 412 moves downward, the first connecting member 42 becomes looser, so that the first connecting member 42 can bear a certain weight for the lower hinge assembly 3, effectively preventing the door and window from detaching.

[0041] More specifically, a limit member 421 is provided at one end of the first connecting member 42 connected to the second sliding portion 4132 to prevent the first connecting member 42 from being separated from the adjusting member 412 , so that the first connecting member 42 can bear more weight.

[0042] Furthermore, the lower hinge assembly 3 includes a base plate 31, a connecting rod assembly, and a hinge assembly 35. The base plate 31 is provided on the first target installation object 1, and the hinge assembly 35 is provided on the second target installation object 2. One end of the connecting rod assembly is hinged to the base plate 31, and the other end is hinged to the hinge assembly 35. The connecting rod assembly can be unfolded or folded, and the rotating member 43 can be rotatably connected to the hinge assembly 35. More specifically, the connecting rod assembly includes a first connecting rod 32, a second connecting rod 33, and a third connecting rod 34. One end of the first connecting rod 32 and the second connecting rod 33 are respectively hinged at different positions on the base plate 31, and the middle portion of the first connecting rod 32 is hinged to the middle portion of the second connecting rod 33. The other end of the first connecting rod 32 is hinged to one end of the hinge assembly 35, the other end of the second connecting rod 33 is hinged to one end of the third connecting rod 34, the third connecting rod 34 is hinged to one end of the hinge assembly 35, and the other end of the hinge assembly 35 is connected to the first connecting member 42.

[0043] In this embodiment, the base plate 31 is set on the first target installation object 1. During the opening process of the door and window, the multiple connecting rods hinged on the base plate 31 are in a gradually opening state, and the hinge assembly 35 is connected to the first connecting member 42, so that the entire lower hinge assembly 3 can bear more weight.

[0044] Specifically, the hinge assembly 35 includes a second fixing member 351 and a first hinge shaft 352. The second fixing member 351 is clamped on the second target installation object 2. A hinge hole 353 is provided on the second fixing member 351. The other end of the first connecting rod 32 is hinged below the hinge hole 353. The rotating member 43 is rotatably set in the hinge hole 353 through the first hinge shaft 352, and the first connecting member is connected to the rotating member 43. The second fixing member 351 is hinged to one end of the first connecting rod 32 and a protrusion 354 is radially provided. The protrusion 354 is connected to the second target installation object 2, and the third connecting rod 34 is hinged on the protrusion 354.

[0045] In this embodiment, the first connecting member 42 is connected to the rotating member 43, and the rotating member 43 can be rotatably set on the second fixing member 351. The second fixing member 351 is hinged to the first connecting rod 32, that is, the second fixing member 351 moves with the movement of the first connecting rod 32, and the rotating member 43 rotates during the movement of the second fixing member 351, which does not affect the opening and closing of the door and window, and the first connecting member 42 is connected to the rotating member 43 to replace the hinge assembly 3 to bear more weight. The second fixing member 351 is clamped on the second target installation object 2, and one end of the second fixing member 351 is radially provided with a protrusion 354, which can more firmly fix the second fixing member 351. The second fixing member 351 is connected to the second target installation object 2. Specifically, the protrusion 354 is provided with at least one threaded hole (not shown), which can be connected to the second target installation object 2 through a second connecting member (not shown). The protrusion 354 is connected to the second target installation object 2, and the third connecting rod 34 is hinged on the protrusion 354. On the basis of the hinge connection between the second fixing member 351 and the first connecting rod 32, the stability of the connection between the lower hinge assembly 3 and the second target installation object 2 can be effectively improved to prevent the doors and windows from falling off. Specifically, the second connecting member is a screw, which is economical, practical and easy to produce.

[0046] Combine Figure 6-7 As shown, the hinge assembly 35 includes a second fixing member 351, a first hinge shaft 352 and a connecting plate 355. The second fixing member 351 is connected to the second target installation object 2 through a second connecting member. A hinge hole 353 is provided on the second fixing member 351. The other end of the first connecting rod 32 is hinged below the hinge hole 353. The rotating member 43 is rotatably set in the hinge hole 353 through the first hinge shaft 352, and the first connecting member is connected to the rotating member 43. One end of the connecting plate 355 is detachably connected to the second fixing member 351, and the other end is connected to the second target installation object 2. The third connecting rod 34 is hinged to the connecting plate 355.

[0047] In this embodiment, the second fixing member 351 is connected to the second target installation object 2 through the second connecting member. Compared with the clamping device on the second target installation object 2 in the above embodiment, the connection between the second fixing member 351 and the second target installation object 2 is tighter and more stable, and the connection between the hinge assembly 35 and the second target installation object 2 is strengthened by connecting the connecting plate 355 to the second target installation object 2. The connecting plate 355 and the second fixing member 351 are detachably connected for easy replacement.

[0048] Combine Figure 8-9 As shown, the hinge hole 353 includes a first hinge hole 3531 and a second hinge hole 3532 , the other end of the first connecting rod 32 is hinged below the first hinge hole 3531 , and the rotating member 43 is rotatably disposed in the second hinge hole 3532 through the first hinge shaft 352 .

[0049] In this embodiment, the first connecting rod 32 and the rotating member 43 are hinged in different hinge holes from the second fixing member 351, which can prevent interference between the two and facilitate component replacement. Specifically, the other end of the first connecting rod 32 is hinged in the second hinge hole 3532 via the second hinge shaft 356, facilitating the flexible opening and closing of the lower hinge assembly 3.

[0050] Furthermore, a plurality of intermediate connecting rods (not shown) are provided between the two connecting rods connected by hinge in the lower hinge assembly 3 according to their height, thereby ensuring the smooth rotation of the hinged connecting rods.
