Each component of the hinge works together according to different functions to achieve various movements of bearing, connecting, rotating, and supporting combined doors and windows.

[0003] For example, the Chinese utility model patent with the patent number 202320714283.0 provides a hinge structure that can achieve a resistance-type opening, including a movable hinge cup, a rocker arm assembly, and a connecting arm. By setting a resistance structure on the rocker arm assembly and between the rocker arm assembly and the connecting arm, when a user rotates and opens the door body to a certain angle, resistance can be generated, thereby realizing the resistance-type opening of the door body, preventing the door body from shaking, and at the same time, it can also play a role in buffering and shock absorption.

[0004] However, after the existing hinge is installed, there is no limiting structure to limit the door body after the door body is opened, resulting in the door body being prone to shaking and affecting the normal use of the door body. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides an anti-shake structure of a hinge and a hinge to solve the technical problem that after the existing hinge is installed, there is no limiting structure to limit the door body after the door body is opened, resulting in the door body being prone to shaking and affecting the normal use of the door body as mentioned in the above background art.

[0013] In a preferred embodiment, a reset assembly connected to the rocker arm is further provided in the housing to drive the rotated rocker arm to reset through the reset assembly.

[0014] In a preferred embodiment, the reset assembly includes:

[0015] A mounting rod, provided at the hinge joint of the housing and the connecting frame;

[0016] A contact rod, provided on the rocker arm; and

[0017] A torsion spring, sleeved on the mounting rod, with one end abutted against the housing and the other end abutted against the contact rod.

[0018] In a preferred embodiment, a buffer mechanism connected to the rocker arm is further provided in the housing to buffer the movement of the rocker arm through the buffer mechanism.

[0042] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0043] Embodiment:

[0044] As Figure 1 、 4 shown, the present utility model provides an anti-shake structure for a hinge, which includes a housing 101. One end of the housing 101 is hinged with a connecting frame 401, and one end of the connecting frame 401 is hinged with a hinge cup 501. A first mounting fin 106 is provided on the housing 101, and a second mounting fin 502 is provided on the hinge cup 501. When in use, the housing 101 is mounted in the mounting area through the first mounting fin 106, and the hinge cup 501 is mounted on the door body through the second mounting fin 502. The mounting methods of the first mounting fin 106 and the second mounting fin 502 can be bolt fixing or welding fixing. After installation, when the door body rotates, it drives the hinge cup 501 to move accordingly. Both ends of the connecting frame 401 can move along their hinge points to adapt to the movement of the hinge cup 501.

[0045] As Figure 2 、 3 shown, in this embodiment, a card slot 402 is provided on the connecting frame 401, and a limiting protrusion 403 is provided on the card slot 402. A rocker arm 301 is hinged on the housing 101. One end of the rocker arm 301 is hinged with the hinge cup 501, and a limiting component is provided at the end of the rocker arm 301. The limiting component can be clamped in the card slot 402 and abuts against the limiting protrusion 403. The limiting component includes a limiting frame 304, and a rod body that can be engaged with the card slot 402 is provided on the limiting frame 304. It can be understood that in some preferred embodiments, the limiting frame 304 is U-shaped. The connecting frame 401 and the hinge cup 501 are hinged through one end of the limiting frame 304, and the rocker arm 301 and the hinge cup 501 are hinged through the other end of the limiting frame 304.

[0046] The U-shaped limiting frame 304 can hinge both the connecting frame 401 and the rocker arm 301 on the hinge cup 501. When the door body opens and closes to drive the connecting frame 401 to move, the connecting frame 401 and the rocker arm 301 swing relatively, so that the limiting frame 304 rotates on the connecting frame 401. When the door body is opened to the limit state, one end of the limiting frame 304 can be clamped in the card slot 402 after passing through the limiting protrusion 403, and the movement of the limiting frame 304 is limited by the limiting protrusion 403, preventing the limiting frame 304 from disengaging from the card slot 402, thereby limiting the opened door body and preventing the door body from shaking or even closing automatically under slight external force.

[0047] AsFigures 2 to 4 As shown, in this embodiment, a reset assembly connected to the rocker arm 301 is further provided in the housing 101, and the rocker arm 301 is reset after being rotated by driving the reset assembly. The reset assembly includes a mounting rod 104 provided at the hinge of the housing 101 and the connecting frame 401, an abutting rod 302 is provided on the rocker arm 301, and a torsion spring 105 is sleeved on the mounting rod 104, one end of the torsion spring 105 abuts against the housing 101, and the other end abuts against the abutting rod 302.

[0048] During the process of opening the door body, the movement of the rocker arm 301 drives the abutment rod 302 to move. During the movement, the abutment rod 302 drives the torsion spring 105 to deform by abutting against the torsion spring 105. During the process of closing the door body, it is only necessary to slightly move the door body to make the limit frame 304 disengage from the slot 402 and the limit protrusion 403, so that the rocker arm 301 can be reset under the reset ability of the torsion spring 105, thereby achieving complete closure of the door body, thereby eliminating the need for manual large-scale movement of the door body to make it completely closed.

[0049] like Figure 2 , 3 As shown in Figures 5 and 6, in this embodiment, a buffer mechanism connected to the rocker arm 301 is further provided in the housing 101, and the movement of the rocker arm 301 is buffered by the buffer mechanism. The buffer mechanism includes a transmission disc 201 hinged on the housing 101, a driving rod 202 is provided on the transmission disc 201, a slide groove 303 is provided on the rocker arm 301, and the driving rod 202 is slidably clamped in the slide groove 303. A damping assembly connected to the transmission disc 201 is provided on the housing 101, and the rotation of the transmission disc 201 is buffered by the damping assembly. The damping assembly includes a mounting cylinder 102 and a piston rod 103, the end of the mounting cylinder 102 is hinged to the housing 101, the piston head at one end of the piston rod 103 is slidably clamped in the mounting cylinder 102, and the other end is hinged to the transmission disc 201.

[0050] During the process of closing the door body, the rocker arm 301 is driven to rotate along the hinge point between it and the shell 101. During the movement, the rocker arm 301 drives the transmission plate 201 to rotate along the hinge point between it and the shell 101 through the cooperation of the slide groove 303 and the drive rod 202. During the rotation of the transmission plate 201, the piston head at the end of the piston rod 103 can slide in the mounting cylinder 102, and the movement of the transmission plate 201 is buffered by the resistance generated by the air pressure, thereby buffering the movement of the door body, making the movement of the rocker arm 301 and the door body smoother, avoiding the door body from moving too fast during closing and causing collision, thereby improving the safety and reliability of the door body when in use.

[0051] like Figure 2 , 3As shown, in this embodiment, a hinge includes the anti-shake structure of the above-mentioned hinge, which can prevent the door body from shaking after being opened and improve the stability of the door body installation.

[0052] Specific usage method and beneficial effects of the present utility model:

[0053] When the anti-shake structure of the hinge and the hinge are in use, the housing 101 and the hinge cup 501 are respectively fixed on the installation area and the door body. During the opening and closing process of the door body, the hinge cup 501 is driven to move, and the connecting frame 401 moves to adapt to the position change of the door body. During the movement of the hinge cup 501, the rocker arm 301 is driven to move, and a relative movement occurs between the rocker arm 301 and the connecting frame 401. In the initial state, the limiting component on the rocker arm 301 is not clamped in the card slot 402. When the door body is opened to the limit position, the limiting component passes through the limiting protrusion 403 and is clamped in the card slot 402. The position of the limiting component is simply limited by the limiting protrusion 403 to effectively prevent the door body from shaking and improve the stability of the door body after being opened.

[0054] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments.
