Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to a rectangular buffer glass hinge. Background Art

[0002] Glass door clamps are hardware accessories used to clamp glass doors and ensure the normal operation of the doors. They are widely used in glass doors and windows, bathroom doors, and shower rooms.

[0003] The glass door clamp in the prior art is equipped with a buffer device, which can make the glass door open and rotate flexibly and automatically return to its original position to keep the glass door in a closed state. The reset mainly relies on the spring force. Since the glass door is heavy and large in size, the spring is easily affected by inertia when resetting, resulting in an unstable reset speed of the glass door and a very fast speed. Therefore, when the glass door is closed, due to the high speed, the glass door needs to be opened and closed back and forth many times before it gradually stops in the closed position, causing unnecessary wear and waste on the glass door clamp.

[0004] As authorized by the applicant on July 28, 2023, a two-way buffered glass door hinge with announcement number CN219431631U is disclosed, which includes a fixed seat 1, a movable seat 2 and a hinge seat 3. The fixed seat 1 is fixedly connected to the hinge seat 3, and the movable seat 2 is rotatably mounted on the hinge seat 3 through a rotating shaft 4. The fixed seat 1 and the movable seat 2 adopt a 180-degree double-plywood structure, wherein the hinge seat 3 is provided with an installation cavity 31 for accommodating a damper 5 and a first spring 6. The damper 5 provides a buffering effect when the rotating shaft 4 rotates back to its original position, and a second spring 7 is provided on the outer side of the damper 5. The first spring 6 and the second spring 7 provide a return effect for the rotating shaft 4 during the rotation process. By arranging a damper 5 in the hinge seat 3, a buffering effect is provided for the rotating shaft 4 when it rotates back to its original position, so as to avoid unnecessary wear and impact caused by the glass door closing too quickly. In addition to arranging a first spring 6 to provide rebound force on one side of the damper 5, a second spring 7 is also arranged on the outside of the damper, which does not take up too much installation space and also has the performance of double spring rebound force; in this structure, the hinge seat 3 is directly fixed to the side of the fixed seat 1 by bolts, and the connection strength is poor, and it cannot be used for extra-large glass doors. After long-term use on extra-large glass doors, the connection strength may be insufficient, resulting in the position of the buffer structure being offset, affecting the normal operation of the hinge; therefore, optimization and improvement are needed.
