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 durable hinge to solve the above problems

Embodiment

[0025] Such as Figure 1 to Figure 7 As shown, a durable 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 , and the adjusting element 29 is set in the liquid circuit 6 to control the liquid flow and adjust the damping effect.

[0026] 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. Th...

Abstract

The invention discloses a durable hinge, and relates to the field of hinges. The durable hinge comprises an upper shell, a lower shell and a positioning block, wherein the upper shell and the lower shell are detachably connected, and the positioning block is arranged between the upper shell and the lower shell; a cavity is formed in the positioning block, a buffer mechanism and a driven rotating mechanism connected with a door are arranged in the cavity, the buffer mechanism is used for reducing the rotating speed of the driven rotating mechanism, a liquid loop is further arranged in the buffer mechanism, and the liquid loop is used for improving the rotating stability of the driven rotating mechanism. According to the durable hinge, the driven rotating mechanism is arranged to drive the buffer mechanism to move, so that the resistance of a buffer block, a sliding block and a spring needs to be overcome when the door rotates, then the speed is reduced, and the impact on the door and a door frame is reduced; and the liquid loop is arranged in the buffer mechanism, so that the resonance amplitude of each mechanical element in the device is reduced while the speed is further reduced, the rotating stability of the driven rotating mechanism is improved, the damage of the mechanical elements is reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the field of hinges, in particular to a durable 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 self-weight and excessive 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 durable 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 durable hinge, comprising a detachably connected upper shell, a lower shell, and a positioning block installed between them, a cavity is provided in the positioning blo...
