A hydraulic hinge with adjustable buffer speed for double opening

Abstract

The invention provides a hydraulic hinge with double-opening and adjustable buffer speed, which includes: a fixed seat and a movable seat, the central rotating shaft runs through the rotating shaft installation hole provided on the rotating shaft mounting seat and is hinged with the movable seat, and the speed adjustment gear shaft is installed on the rotating shaft. In the gear shaft installation hole on the seat, the buffer spring is installed in the spring installation groove provided on the fixed seat. The spring rear end is in contact with the special-shaped stepped slope of the gear shaft body; the buffer oil cylinder is installed on the movable seat, the buffer wheel is installed at one end of the buffer oil cylinder, and the buffer wheel is in contact with the buffer shell sleeved on the outside of the fixed seat. The invention is ingenious in design, can realize the adjustable return buffer speed, improves the service life and buffer effect of the hinge, ensures that the door body can move at a uniform speed during the automatic reset process, and can realize the inner and outer double hinges under the premise of ensuring that the waterproof strip is uninterrupted. Door opening function.

Description

technical field [0001] The invention relates to the technical field of hinges, in particular to a double-opening hydraulic hinge with adjustable buffer speed. Background technique [0002] Hydraulic buffer hinge is a kind of hinge, also known as damping hinge, which refers to providing a kind of noise-absorbing buffer hinge that uses high-density oil body to flow directionally in a closed container to achieve ideal buffering effect. It relies on a brand new The technology adapts to the closing speed of the door, reduces the impact force, and forms a comfortable effect when closing. Even if the door is closed with force, it will be closed gently, ensuring perfect and soft movement. The existing hydraulic buffer hinges generally have the following defects: (1) Generally, a single spring buffer structure is 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. With the spring buffer structure, ...

AI Technical Summary

Problems solved by technology

The existing hydraulic buffer hinges generally have the following defects: (1) Generally, a single spring buffer structure is 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. With the spring buffer structure, the speed of the door body during the automatic reset process cannot be buffered at a constant speed; (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

(3) The buffer hinge of the glass door is too large, which affects the appearance

(4) It is impossible to make the waterproof strip uninterrupted, which affects the waterproof and airtightness of the room
