Furniture tilt-up door opening-closing force adjusting mechanism

Abstract

Disclosed is a furniture tilt-up door opening-closing force adjusting mechanism. The furniture tilt-up door opening-closing force adjusting mechanism comprises a locking and unlocking device arranged on a furniture tilt-up door and a tilt-up device disposed on a furniture cabinet body. The furniture tilt-up door is turned over and opened or closed on the tilt-up device of the furniture cabinet body through the locking and unlocking device. The tilt-up device comprises a positioning element, a spring and a connecting arm assembly. One end of the connecting arm assembly is connected with the locking and unlocking device, and the other end of the connecting arm assembly is connected with the positioning element. A support is disposed on the positioning element. An adjusting screw rod is mounted on the support. A pushing element is arranged between the positioning element and the support. The pushing element is in threaded connection with the adjusting screw rod. One end of the spring is connected with the pushing element, and the other end of the spring is connected with the connecting arm assembly. A tool acts on an acting part of the adjusting screw rod, the adjusting screw rod is positioned and rotated on the support, and one end of the spring and the pushing element are driven to perform displacement relative to the support, so that the elastic force, exerted on the connecting arm assembly, of the other end of the spring is increased or decreased, accordingly the opening and closing force adjustment of the tilt-up device is achieved finally, and the practicability is high.

Description

technical field [0001] The invention relates to a mechanism for adjusting the opening and closing strength of an upward flap door of furniture. Background technique [0002] The Chinese patent document number is CN202039710U, which discloses a hinge on November 16, 2011. The curved end of the first rotating arm of this structure is rotatably connected to the base plate, and the curved end of the second rotating arm is rotatably connected to the base plate. The two ends of the above-mentioned connecting arms that can overlap with the respective straight ends of the first rotating arm and the second rotating arm at the same time are rotatably connected with the respective straight ends of the first rotating arm and the second rotating arm respectively, and the connecting arms are located at the first Between the rotating arm and the second rotating arm, the bent end of the first rotating arm is hinged with the free end of the movable rod of the gas rod, and the fixed rod of th...

Problems solved by technology

It is said that this structure can reduce noise, and the closing or opening movement of the cabinet door is more flexible. During the movement of the cabinet door, the overall translational movement can avoid the situation that ordinary cabinet doors may hit the head; however, the upper The flap hinges only use the elastic device to achieve buffering and damping, and the force during the closing movement or opening movement cannot achieve a uniform effect, and the elastic device has a large friction force and high noise when the upper flap is hinged to open and close, which cannot meet the needs of users.
