Problems solved by technology

[0002] Existing hinges generally include: a movable part connected to the door and a fixed part connected to the door frame. The movable part rotates in the fixed part, but it is not suitable for some glass doors or large and heavy doors, and the door is opened or closed. Due to its own weight and excessive speed, it may cause damage to the glass door or a strong impact on the frame, which will affect the service life. Therefore, it is necessary to provide a buffer hinge to solve the above problems

Embodiment

[0022] Such as Figure 1 to Figure 7 As shown, a buffer hinge includes a detachably connected upper shell 1, a lower shell 2, and a positioning block 3 installed between the two. The positioning block 3 is provided with a cavity 7, and the cavity A buffer mechanism 4 and a driven rotating mechanism 5 connected to the door are installed inside the buffer mechanism 4. The buffer mechanism 4 is used to reduce the rotation speed of the driven rotating mechanism 5. A liquid circuit 6 is also provided in the buffer mechanism 4. The liquid The circuit 6 is used to improve the rotation stability of the driven rotating mechanism 5 .

[0023] In this embodiment, the buffer mechanism 4 includes a slider 8 sliding in the chamber 7, the slider 8 is provided with a blind hole 9, and the blind hole 9 is inserted with the insertion rod 10 and the end cap is installed. 11. The other end of the insertion rod 10 passes through the end cover 11 and is installed on the inner wall of the chamber 7...

Abstract

The invention discloses a buffer hinge, which relates to the field of hinges, and comprises a detachably connected upper shell, a lower shell and a positioning block installed between the two. A cavity is arranged in the positioning block, and a Install a buffer mechanism and a driven rotation mechanism connected with the door, the buffer mechanism is used to reduce the rotation speed of the driven rotation mechanism, and a liquid circuit is also provided in the buffer mechanism, and the liquid circuit is used to improve the speed of the driven rotation mechanism Rotational stability, the invention needs to overcome the resistance of the buffer block, slider, and spring when the door rotates, thereby reducing the speed and reducing the impact on the door and the door frame. By setting a liquid circuit in the buffer mechanism, no matter whether the door is opened or closed, The door still needs to overcome the resistance of the liquid during the rotation process, and at the same time of further deceleration, it helps to reduce the resonance amplitude of the mechanical components in the device, reduces the damage of the mechanical components, and prolongs the service life of the device. The device is easy to install and disassemble. Wide range of applications.

Description

technical field [0001] The invention relates to the field of hinges, in particular to a buffer hinge. Background technique [0002] Existing hinges generally include: a movable part connected to the door and a fixed part connected to the door frame. The movable part rotates in the fixed part, but it is not suitable for some glass doors or large and heavy doors, and the door is opened or closed. Sometimes, due to reasons such as self-weight and too fast speed, the glass door may be damaged or the frame may be strongly impacted, which will affect the service life. Therefore, it is necessary to provide a buffer hinge to solve the above problems. Contents of the invention [0003] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0004] A buffer hinge, comprising a detachably connected upper shell, a lower shell, and a positioning block installed between them, a cavity is provided in the pos...
