Problems solved by technology

It is said that even if the hinge is subjected to impact, the above-mentioned structure may prevent one end of the torsion spring from detaching from the receiving plate portion of the spring by limiting the lateral deviation of one end of the torsion spring; however, since the diameter of the torsion spring steel wire is small, the torsion The contact part between the supporting foot of the spring and the parts is very small, almost point contact, so the pressure at the contact is strong, resulting in serious wear between the torsion spring and the parts, affecting the life of the torsion spring and even the entire hinge

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] see Figure 1-Figure 4 , the concealed hinge for this furniture, including the movable cup holder 3 arranged on the furniture door body, the connecting arm 1 arranged on the main body of the furniture, the movable cup holder 3 and the connecting arm 1 are connected by a rocker arm, and the connecting arm 1 is set There is a damper 9, and the hinge is also provided with an elastic member 6 that at least generates an opening and closing force on the movable cup holder 3. One end of the damper 9 is arranged in the connecting arm 1, and the other end is at least in cooperation with the pendulum 8 during the closing process of the hinge. Connection; a pin shaft 7 or a roller is arranged between the elastic member 6 and the rocker arm, and the two are connected to each other by sliding or rolling at least during the hinge closing process through the pi...

Abstract

A blind hinge for furniture comprises a movable cup holder arranged on a furniture door body and a connecting arm arranged on a furniture main body, wherein the movable cup holder and the connecting arm are connected through a rocker arm; a damper is arranged in the connecting arm; the blind hinge is also provided with an elastic piece which can at least produce an open-close action force to the movable cup holder. The blind hinge is characterized in that one end of the damper is arranged in the connecting arm, and the other end is connected with a swaying block in the hinge closing process at least; a hinge pin or a rotary drum is arranged between the elastic piece and the rocker arm, which are connected in a mutually sliding or rolling manner through the hinge pin or the rotary drum in the hinge closing process at least. Through the above structural improvement that the hinge pin or the rotary drum is arranged between the elastic piece and the rocker arm, which are connected in a mutually sliding or rolling manner through the hinge pin or the rotary drum in the hinge closing process at least, the pressure intensity at the contact part between the elastic piece and the rocker arm is greatly reduced, rigid friction between the elastic piece and the rocker arm is reduced, abrasion is reduced, and the product service life is prolonged; meanwhile, the purpose that the hinge is smooth and reliable in opening and closing is achieved.

Description

technical field [0001] The invention relates to a hinge, in particular to a concealed hinge for furniture. Background technique [0002] Chinese Patent Document No. CN1873178 disclosed a hinge device on December 6, 2006, which has: an elongated first body installed on the furniture body; a cover-shaped second body installed on the door; the second body The first and second chain links rotatably connected to the first body; and the torsion spring, one end of the torsion spring pushes the spring receiving plate of the first chain link, thereby, the second body faces the first The main body rotates and applies force, one end of the torsion spring is disposed between the side wall of the first main body and the side wall of the second link, the gap between the spring receiving plate and the side wall of the first main body, and the gap between the spring receiving plate and the side wall of the second link. The gaps between the side walls of the second link are all smaller than...
