A hydraulic hinge with adjustable one-way opening and closing door positioning angle and buffer speed

Abstract

The invention provides a hydraulic hinge with adjustable one-way door opening and closing positioning angle and buffering speed, comprising: a movable seat and a fixed seat; It is used to hinge the movable seat and the fixed seat. The spring buffer assembly and the buffer cylinder are respectively installed in the movable seat and are in contact with the concave surfaces on the buffer shaft respectively. The gear shaft is installed in the movable seat and is in contact with the spring buffer assembly. The copper sleeve assemblies are respectively installed on the left and right ends of the buffer rotating shaft, one of the two pointed ingots is in contact with the angle adjusting member, and the other is in contact with the copper sleeve assembly. The invention can realize the adjustable angle of door closing positioning, adjustable return buffer speed, and adopts the structure in which the buffer spring and the buffer oil cylinder cooperate, which can improve the service life and safety of the glass door. It moves at a uniform speed to avoid potential safety hazards caused by impact during the reset process.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a hydraulic hinge with adjustable positioning angle and buffering speed of one-way opening and closing doors. Background technique [0002] Hydraulic buffer hinge is a kind of hinge, also known as damping hinge, which means to provide a kind of sound-absorbing buffer hinge that uses high-density oil to flow directionally in a closed container to achieve an ideal buffer effect. The technology is used to adapt to the closing speed of the door, reduce the impact force, and form a comfortable effect when closing. [0003] The existing hydraulic buffer hinges generally have the following defects: [0004] 1) The angle of opening and closing the door cannot be adjusted, and the adaptability is poor, especially in some special occasions where the opening and closing angle of the door is deviated; [0005] 2) The buffer speed cannot be adjusted, and the closing speed of the door page wh...

AI Technical Summary

Problems solved by technology

[0004] 1) The angle of opening and closing the door cannot be adjusted, and the adaptability is poor, especially in some special occasions where the angle of opening and closing the door deviates;

[0005] 2) The buffer speed cannot be adjusted, and the closing speed when the door leaf is automatically closed cannot be adjusted according to actual requirements;

[0006] 3) A single spring buffer structure is generally used. When the external force is uneven or after a long time of use, the buffer function is easily damaged and the service life is short. The speed cannot be buffered at a constant speed
