DETAILED DESCRIPTION

[0012] Example 1, reference Figure 1-3 A high-load-bearing, pad-free, quick-installation casement hinge comprises a fixed slide rail 1, an installation main rod 2, a casement support rod 3, a first support link 41 and a second support link 42, wherein one end of the installation main rod 2 is rotatably connected to one end of the first support link 41, one end of the casement support rod 3 is rotatably connected to the fixed slide rail 1, the other end of the casement support rod 3 is rotatably connected to the installation main rod 2, one end of the second support link 42 is rotatably connected to the middle part of the casement support rod 3, the other end of the first support link 41 and the other end of the second support link 42 are rotatably connected to a slider 5 slidably arranged on the fixed slide rail 1; the installation main rod 2 is provided with a quick-disassembly connector 6 and a pad 7 for connecting to the profile body.

[0013] In this embodiment, the main rod 2 is used for fixed connection with the profile body of the door and window frame. After the installation is completed, the main rod 2 can be pushed to expand outward or fold inward by pushing and pulling the door and window, so as to realize the opening and closing of the door and window. Among them, the casement support rod 3 plays a major supporting role for the main rod 2 when the main rod 2 is expanded outward, the first support link 41 plays a role of auxiliary support and limited rotation for the end of the main rod 2, and the second support link 42 is connected to the casement support rod 3 to play a role of auxiliary support for the casement support rod 3, so that the overall stability of the casement hinge is better. The first support link 41 and the second support link 42 are both slidably connected to the fixed slide rail 1 through the slider 5. When the main rod 2 is expanded outward or folded inward, the first support link 41 and the second support link 42 can slide along the fixed slide rail with the slider. The pad 7 set on the installation main rod 2 can be engaged with the profile body of the door and window frame to improve the stability of the connection between the profile body of the door and window frame and the installation main rod 2. At the same time, the quick-disassembly connector 6 on the installation main rod 2 can be quickly fixedly connected with the profile body. Specifically, the quick-disassembly connector 6 includes a rotating clamping portion 61 and a rotating driving nail 62. The rotating driving nail 62 passes through the installation main rod 2 from the bottom of the installation main rod 2 upward and is driven and connected to the rotating clamping portion 61. The rotating driving nail 62 is rotationally connected to the installation main rod 2. It only needs to twist the rotating driving nail 62 to rotate the rotating clamping portion 61 ninety degrees. The rotating clamping portion 61 clamps the installation slot at the bottom of the profile body to complete the fixed connection between the installation main rod 2 and the profile body of the door and window frame.

[0014] Specifically, a reinforcement anti-collision rod 8 is provided at one end of the installation main rod 2 connected to the first supporting link 41, and the reinforcement anti-collision rod 8 is installed and connected between the installation main rod 2 and the first supporting link 41; the reinforcement anti-collision rod 8 has an anti-collision buffer block 81 extending outwardly along the end of the installation main rod 2. The reinforcement anti-collision rod 8 is arranged between the installation main rod 2 and the first supporting link 41, which can further improve the load-bearing performance and stability of the casement hinge. At the same time, the anti-collision buffer block 81 extending outwardly from the reinforcement anti-collision rod 8 can be matched with the card slot on the fixed slide rail 2, and plays a role of limiting and buffering when the casement hinge is folded.

[0015] Specifically, the pad block 7 on the main rod 2 is arranged at least on one end where the main rod 2 is connected to the first supporting link 41, and can also be arranged on the other end of the main rod 2 as needed, wherein the pad block 7 arranged on one end of the main rod 2 connected to the first supporting link 41 is fixedly connected to the main rod 2 and the reinforced anti-collision rod 8 by rivets. In this way, while fixing the pad block 7, the rivets connecting the main rod 2 and the first supporting link 41 can be cooperated to improve the stability of the connection between the main rod 2 and the reinforced anti-collision rod 8, thereby improving the load-bearing performance and stability of the casement hinge.

[0016] Preferably, the first supporting link 41 and the slider 5 as well as the casement support rod 3 and the fixed slide rail 1 are the main stress points, and large-head rivets are used for rotational connection at the two connections, which can effectively improve the stability of the casement hinge.

[0017] In addition, the stability of the flat hinge can be further improved by providing a stabilizing gasket 9 between the first supporting link 41 and the slider 5 .

[0018] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
