Compact furniture buffer hinge

Abstract

The invention provides a compact furniture buffer hinge, which comprises a hinge cup, a hinge arm and a buffer cylinder, wherein the buffer cylinder is arranged in the arm body cavity of the hinge arm, the hinge cup is connected with the hinge arm by a link mechanism; one end of a hinge tongue is connected with the hinge cup by a third rotating shaft, the other is connected with the hinge arm by afourth rotating shaft; a guide sleeve is sleeved on the surface of the buffer cylinder, the guide sleeve is fixedly installed in the hinge arm, the two sides of the guide sleeve are provided with clamping grooves, n-shaped clips are slidingly installed in the clamping grooves onwards and backwards, the front ends of the clips are connected with the buffer rod of the buffer cylinder, and the leftand right sides of the rear ends of the clips are provided with guide posts. According to the invention, the compact furniture buffer hinge has the following beneficial effects: the guide sleeve is sleeved outside the small cylinder, the guide sleeve is stressed on the hinge tongue by the clips made of metal materials, the guide sleeve achieves the effect of increasing the force receiving area between the guide sleeve and the buffer cylinder, so that the power can be uniformly transmitted to the buffer cylinder, and the service life of the buffer cylinder is ensured.

Description

technical field [0001] The invention belongs to the field of hinges, and in particular relates to a compact furniture buffer hinge, which is suitable for environmental occasions such as wardrobes and cabinets. Background technique [0002] The mainstream furniture hinges in the market generally include hinge cups, hinge arms, linkage mechanisms and buffer cylinders. The hinge cups and hinge arms are connected through linkage mechanisms. The rod mechanism drives the piston rod of the buffer cylinder to expand and contract, thereby increasing the opening and closing resistance of the hinge and playing a buffering role. However, at present, the installation structure of the connecting rod mechanism and the buffer cylinder of the furniture hinge is relatively complicated, which not only affects the assembly efficiency and manufacturing cost, but also in the opening and closing process of the hinge, in addition to the telescopic movement of the piston rod of the buffer cylinder, ...

AI Technical Summary

Problems solved by technology

However, at present, the installation structure of the connecting rod mechanism and the buffer cylinder of the furniture hinge is relatively complicated, which not only affects the assembly efficiency and manufacturing cost, but also in the opening and closing process of the hinge, in addition to the telescopic movement of the piston rod of the buffer cylinder, the buffer cylinder as a whole also exists. A small swing causes the sealing ring of the buffer cylinder to work in an abnormal state for a long time, which is prone to wear and tear, thereby shortening the service life of the buffer cylinder
