Description

Technical Field

[0001] This utility model relates to the field of hardware profile technology, and in particular to a high load-bearing, pad-free, quick-installation hinge. Background Technology

[0002] Casement hinges, as a type of opening and closing connector with good stability, high adjustability, and wide applicability, are widely used in operable doors and windows. Currently, when installing casement hinges with door and window frame profiles, it is necessary to install spacers on the frame profiles before connecting them to improve the stability of the connection. Furthermore, tightening bolts during installation makes the process relatively complicated, and subsequent fine-tuning is also cumbersome, affecting installation efficiency. This also impacts the stability of the connection between the door / window frame and the casement hinge. Utility Model Content

[0003] The purpose of this utility model is to provide a swing hinge, specifically a high-load-bearing swing hinge that can be quickly installed without a pad.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a high-load-bearing, pad-free, quick-installation swing hinge, comprising a fixed slide rail, a mounting main rod, a swing support rod, a first support connecting rod, and a second support connecting rod. One end of the mounting main rod is rotatably connected to one end of the first support connecting rod. One end of the swing support rod is rotatably connected to the fixed slide rail, and the other end of the swing support rod is rotatably connected to the mounting main rod. One end of the second support connecting rod is rotatably connected to the middle of the swing support rod. The other ends of the first and second support connecting rods are rotatably connected to a slider slidably mounted on the fixed slide rail. The mounting main rod is provided with quick-release connectors and pads for connecting with the profile body.

[0005] Specifically, a reinforced anti-collision bar is provided at one end of the main mounting rod that connects to the first support link. The reinforced anti-collision bar is installed between the main mounting rod and the first support link. An anti-collision buffer block extends outward from the end of the main mounting rod.

[0006] Specifically, the pads are fixedly connected to the mounting main rod and the reinforced anti-collision rod by rivets.

[0007] Specifically, the first support link and the slider, as well as the swing support link and the fixed slide rail, are all connected by large-headed rivets.

[0008] Specifically, a stabilizing pad is provided between the first support link and the slider.

[0009] Specifically, the quick-release connector includes a rotating snap-fit ​​part and a rotating drive pin. The rotating drive pin passes through the mounting main rod from the bottom upwards and is driven to connect with the rotating snap-fit ​​part. The rotating drive pin is rotatably connected to the mounting main rod.

[0010] The beneficial effects of this utility model are as follows: by setting quick-release connectors and pads on the main mounting rod to connect with the profile body of the door and window frame, quick installation can be achieved and stability can be improved; at the same time, a reinforced anti-collision bar is set between the main mounting rod and the first support connecting rod, which not only plays an anti-collision role but also improves the stability of the swing hinge; and by using large-headed rivets at the rotating connection point that plays a major supporting role, the stability and load-bearing capacity of the swing hinge can be further improved.

[0014] Example 1, referring to Figure 1-3 A high-load-bearing, pad-free, quick-installation swing hinge includes a fixed slide rail 1, a mounting main rod 2, a swing support rod 3, a first support connecting rod 41, and a second support connecting rod 42. One end of the mounting main rod 2 is rotatably connected to one end of the first support connecting rod 41. One end of the swing support rod 3 is rotatably connected to the fixed slide rail 1, and the other end of the swing support rod 3 is rotatably connected to the mounting main rod 2. One end of the second support connecting rod 42 is rotatably connected to the middle of the swing support rod 3. The other ends of the first support connecting rod 41 and the second support connecting rod 42 are rotatably connected to a slider 5 slidably mounted on the fixed slide rail 1. The mounting main rod 2 is equipped with a quick-release connector 6 and a pad 7 for connecting to the profile body.

[0015] In this embodiment, the main mounting rod 2 is used to fix and connect to the profile body of the door and window frame. After installation, the main mounting rod 2 can be pushed outward or folded inward by pushing and pulling the door and window, thereby realizing the opening and closing of the door and window. Among them, the casement support rod 3 plays a major supporting role for the main mounting rod 2 when it is extended outward. The first support connecting rod 41 plays an auxiliary supporting role and limits the rotation of the end of the main mounting rod 2. The second support connecting rod 42 is connected to the casement support rod 3 and plays an auxiliary supporting role for the casement support rod 3, thereby making the overall stability of the casement hinge better. The first support connecting rod 41 and the second support connecting rod 42 are both slidably connected to the fixed slide rail 1 through the slider 5. When the main mounting rod 2 is extended outward or folded inward, the first support connecting rod 41 and the second support connecting rod 42 can slide along the fixed slide rail with the slider. The pad 7 on the main mounting rod 2 can be engaged with the profile body of the door and window frame, improving the stability of the connection between the profile body and the main mounting rod 2. At the same time, the quick-release connector 6 on the main mounting rod 2 can be quickly fixed to the profile body. Specifically, the quick-release connector 6 includes a rotating locking part 61 and a rotating drive pin 62. The rotating drive pin 62 passes through the main mounting rod 2 from the bottom and drives the rotating locking part 61. The rotating drive pin 62 is rotatably connected to the main mounting rod 2. By simply turning the rotating drive pin 62 to rotate the rotating locking part 61 by 90 degrees, the rotating locking part 61 locks into the mounting slot at the bottom of the profile body, thus completing the fixed connection between the main mounting rod 2 and the profile body of the door and window frame.

[0016] Specifically, a reinforcing anti-collision bar 8 is provided at one end of the mounting main rod 2 that connects to the first support connecting rod 41. The reinforcing anti-collision bar 8 is installed between the mounting main rod 2 and the first support connecting rod 41. An anti-collision buffer block 81 extends outward from the end of the mounting main rod 2 along the reinforcing anti-collision bar 8. The reinforcing anti-collision bar 8, located between the mounting main rod 2 and the first support connecting rod 41, can further improve the load-bearing capacity and stability of the swing hinge. At the same time, the anti-collision buffer block 81 extending outward from the reinforcing anti-collision bar 8 can cooperate with the slot on the fixed slide rail 2, playing a role in limiting and buffering when the swing hinge is folded.

[0017] Specifically, the pad 7 on the mounting main rod 2 is set at least at the end where the mounting main rod 2 is connected to the first support connecting rod 41, and can also be set at the other end of the mounting main rod 2 as needed. The pad 7 set at the end of the mounting main rod 2 connected to the first support connecting rod 41 is fixedly connected to the mounting main rod 2 and the reinforced anti-collision rod 8 by rivets. In this way, while fixing the pad 7, it can work with the rivets connecting the mounting main rod 2 and the first support connecting rod 41 to improve the stability of the connection between the mounting main rod 2 and the reinforced anti-collision rod 8, thereby improving the load-bearing capacity and stability of the swing hinge.

[0018] Preferably, the main stress points are between the first support link 41 and the slider 5, and between the swing support rod 3 and the fixed slide rail 1. The two connections are connected by large-head rivets, which can effectively improve the stability of the swing hinge.

[0019] In addition, the stability of the swing hinge can be further improved by setting a stabilizing shim 9 between the first support link 41 and the slider 5.

[0020] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
