Problems solved by technology
[0004] When the hinge is installed, the left and right leaf plates of the hinge need to be opened. The above structure is equipped with an energy storage spring, and the elastic force of the energy storage spring makes it difficult to open the leaf plate; in addition, the damping mechanism in the above structure cannot freely adjust the opening and closing The speed cannot meet the consumer requirements well

The invention relates to a buffering hinge. The buffering hinge comprises a first hinge piece and a second hinge piece which can coaxially and relatively rotate, a first sleeve is arranged on one sideof the first hinge piece, a second sleeve is arranged on one side of the second hinge piece, a mandrel is coaxially sleeved with the first sleeve and the second sleeve, and the mandrel comprises a first fixing sleeve and a second fixing sleeve which are coaxially arranged; the second fixing sleeve is fixed on a driving shaft, the upper end of the driving shaft is provided with a driving sleeve, the upper part of the driving shaft extends into the first fixing sleeve from a lower port of the first fixing sleeve, and the driving sleeve is accommodated in the first fixing sleeve; and an engagement-disengagement sleeve and a reset torsional spring are arranged on the position, between the first fixing sleeve and the second fixing sleeve, of the driving shaft in a sleeving mode, an engagement-disengagement mechanism is arranged between the engagement-disengagement sleeve and the driving shaft, one end of the reset torsional spring is clamped into a clamping groove in the lower end of the first fixing sleeve, and the other end of the reset torsional spring is clamped into a clamping groove of the engagement-disengagement sleeve. The buffering, automatic reset and engagement-disengagement functions are achieved, and the buffering hinge has the characteristics of being compact in structure, convenient to adjust and diverse in function.
Description
technical field [0001] The invention relates to a hinge, in particular to a buffer hinge. Background technique [0002] The hinge is mainly used for the movable connection between the door and window and the door frame or window frame. The traditional hinge is formed by the hinge of the door frame hinge and the door leaf hinge on the shaft core. It only has the function of rotating and moving. The traditional hinge has no damping effect. , It cannot prevent wind and at the same time, if it is closed too quickly, it will hit the door frame, and there are also potential safety hazards. [0003] People have designed buffer hinges for this reason, disclose a kind of hydraulic buffer hinges as announcement number CN 06837042B, comprise axle sleeve, the door frame page that is hinged with axle sleeve and be located at the axle core in axle sleeve, axle sleeve outer cover is provided with and The door leaf leaf connected to the shaft core, one end of the shaft core is provided wit...
