Detailed Description
The utility model is described in more detail below with reference to the accompanying drawings. The hardware hinge with the door opening buffering function comprises an upper connecting rod 3 and a lower connecting rod 4, wherein one ends of the upper connecting rod 3 and the lower connecting rod 4 are hinged with a hinge cup 1 through an upper hinge shaft 5 and a lower hinge shaft 6, and the other ends of the upper connecting rod 3 and the lower connecting rod 4 are hinged with a hinge arm 2 through the upper hinge shaft 5 and the lower hinge shaft 6; the hinge cup 1, the hinge arm 2, the upper connecting rod 3 and the lower connecting rod 4 form a four-bar mechanism, which is characterized in that: a bracket 7 is arranged between the upper connecting rod 3 and the lower connecting rod 4, one side of the bracket 7 is concaved inwards to form a positioning hole 71, and the upper hinge shaft 5 passes through the positioning hole 71 to coaxially hinge the upper connecting rod 3 and the bracket 7; the other side of the bracket 7 is outwards bent and provided with a bending part 72, a buffer area 73 is formed between the bending part 72 and the bracket 7 body, the inner end of the bending part 72 is attached to the lower connecting rod 4, after the hinge is opened, the bending part 72 is padded between the upper connecting rod 3 and the lower connecting rod 4, the buffer area 73 is compressed by the relative movement of the upper connecting rod 3 and the lower connecting rod 4, and the impact force generated when the hinge is opened at the maximum angle is buffered.
A limiting table 74 protrudes from the body of the bracket 7 above the positioning hole 71, and the limiting table 74 is clamped on the inner wall of the upper connecting rod 3; the junction of the limit table 74 and the end of the bracket 7 body is in arc transition.
The positioning hole 71 is in an open semicircular shape, and the positioning hole 71 is elastically and snap-fitted outside the upper hinge shaft 5.
The bracket 7, the bending part 72 and the limiting table 74 are integrally made of elastic plastic materials.
The bending part 72 is in a bent hook shape, a guiding curved surface 75 is concavely formed between the bending part 72 and the bracket 7 body, and the lower connecting rod 4 is attached and connected to the guiding curved surface 75.
The middle part of the bracket 7 is hollowed out to form a deformation area 76.
Working principle: in the hinge, a bracket is arranged between an upper connecting rod and a lower connecting rod, one side of the bracket is utilized to form a positioning hole by inwards recessing a body of the bracket, and an upper hinge shaft penetrates through the positioning hole to coaxially hinge the upper connecting rod and the bracket, namely the bracket can swing along the upper hinge shaft.
In order to achieve the purpose of buffering the hinge door, a bending part is arranged at the outer part of the other side of the bracket in a bending way, a buffer zone with a certain space is formed between the bending part and the bracket body, meanwhile, the inner end part of the bending part is connected with the lower connecting rod in a fitting way, when the hinge is opened to a maximum angle, the bending part is lined between the upper connecting rod and the lower connecting rod, and the outer end of the bending part is propped against and clamped on the inner wall of the upper connecting rod. At this moment, the impact force continuously exists, the impact force forces the upper connecting rod and the lower connecting rod to perform relative motion, so that the buffer area is compressed, the impact force is elastically absorbed, the speed of the hinge when the hinge is opened to the maximum angle is slowed down, the impact force of the connecting rod striking the limiting part is reduced, the vibration or rebound when the door is opened to the maximum angle is reduced or even avoided, the loosening risk of the fixing screw for installing the hinge is solved, and the service life of the hinge is effectively prolonged.
