Abstract

The invention relates to a movable automatic sofa leg withdrawing device which comprises a mechanical stretching device and a switching device. The switching device consists of an oversize stay rope switch, a stay cord, a stay rope support, automatic returning rotary shaft rotation parts, a square rotating pipe and springs, the automatic returning rotary shaft rotation parts and the springs are arranged on the two sides of the mechanical stretching device, the square rotating pipe is in rotary connection with a sitting frame installing plate, the automatic returning rotary shaft rotation parts are fixed to the square rotating pipe, and the springs are respectively connected with the sitting frame installing plate and the automatic returning rotary shaft rotation parts. The oversize stay rope switch consists of a stay rope switch housing, a stay rope switch tongue, a stay rope switch central shaft and a stay rope switch torsion spring, wherein the stay rope switch tongue is rotatably installed on the stay rope switch housing through the stay rope switch central shaft and the stay rope switch torsion spring, the stay cord is connected with the stay rope switch tongue and the stay rope support respectively, and the stay rope support is in rotary connection with the sitting frame installing plate through the stay rope switch torsion spring. The movable automatic sofa leg withdrawing device decreases the force required by leg withdrawing and prevents the risk of automatic leg opening.

Description

technical field [0001] The invention relates to an automatic recovery device for the legs of a movable sofa, in particular to a multifunctional automatic recovery device for the legs of a movable sofa, which can automatically fold the legs at a certain angle and adjust the backrest angle to a certain extent. Background technique [0002] At present, the existing movable sofa mechanical stretching device (manual) has three major deficiencies: 1. The power arm of the cable switch is relatively short, and it takes a lot of effort to open it; The use experience for the elderly and children is poor; 3. The sofa is easy to open automatically when it is impacted, and it is easy to cause danger in the process of handling and logistics. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a mechanical stretching device for a movable sofa with a simple structure, s...
