Elastic limiting mechanism for furniture sliding door

Abstract

The invention discloses an elastic limiting mechanism for a furniture sliding door. The elastic limiting mechanism comprises an elastic limiting device. The elastic limiting device comprises a fixed component and a swinging component. The swinging component is arranged on the fixed component. Rollers are correspondingly arranged on the fixed component left and right. A torsional spring is arranged between the swinging component and the fixed component. The swinging component is arranged on the fixed component in an elastic swinging mode through the torsional spring and is provided with a rotating wheel. The rotating wheel elastically swings on the fixed component within a certain range through the matching of the swinging component and the torsional spring. The stress direction of the rotating wheel points to one of the rollers all the time, and two elastic terminals of the rotating wheel are located on the outer side of one of the rollers and at the position within the radial distance of the two rollers. By means of the structural improvement, the elastic limiting mechanism has the characteristics of being simple and reasonable in structure, reliable in performance, convenient to operate, compact in connection between all the components, accurate in positioning, smooth and steady in opening and closing process, free of noise, small in applied force and the like, thereby being high in practicability.

Description

technical field [0001] The invention relates to an elastic limit mechanism for a furniture sliding door. Background technique [0002] The Chinese patent document number is CN201546563U, which disclosed a top suspension rail sliding door automatic closing system on August 11, 2010. It includes a suspension rail, a pulley block with damping, a pulley block, a bumper, and a damping connector. An I-shaped chute, the anti-collision device is placed at both ends of the suspension rail, the pulley block with damping and the pulley block are placed in the suspension rail, the damping connector is installed in the I-shaped chute, and the pulley block with damping is composed of a pulley block and a universal pulley Connector, damping, guide pulley connector and guide pulley, the damper is in the middle, one end is connected to the guide pulley connector, the guide pulley connector is connected to the guide pulley, the other end is connected to the universal pulley connector, and the...

Problems solved by technology

It is said that this structure can achieve a smooth and quiet closing effect by using damping under the condition of large impact force, and effectively protects the moving parts, reduces wear and prolongs the service life; however, since the pulley block is a positioning assembly If there is an error in the production and assembly process or it cannot interact with the chute after long-term use, the sliding door cannot be opened and closed directly, which cannot meet the needs of users.
