A functional sofa sinking mechanical stretching device bracket

Abstract

The invention relates to the technical field of the furniture industry, and discloses a support for a functional sofa sinking mechanical stretching device, including a chassis. The top of the chassis is movably connected with a transverse bar. The number of the transverse bars is two, and two transverse bars are The rods are respectively located on both sides of the center of the cross-section of the bottom of the transverse rod and are equally spaced from the center of the circle, and the left side of the upper surface of the transverse rod is movably connected with a diagonal plate. This functional sofa sinking mechanical stretching device bracket, through the cooperation between the backrest assembly, fixed pin, telescopic assembly, transverse rod and support frame, when the telescopic assembly and the backrest assembly are stretched, their movement positions are always located in the same circle. On the circumference, and located on the left and right sides of the circumference, the balance of the functional sofa is guaranteed, and at the same time, the probability of touching the objects around the sofa during the stretching process of the sofa is reduced, and heavy objects are installed through the inside of the chassis, and its center of gravity is four Located in the middle of the chassis, it improves the stability of this functional sofa.

Description

technical field [0001] The invention relates to the technical field of the furniture industry, in particular to a submerged mechanical extension device support for a functional sofa. Background technique [0002] Functional sofa refers to a sofa with multiple functions. The most common functional sofa is divided into two types, one is manual function extension, manual can also be equipped with shaking and rotating function sofa, and the other is electric function extension, The electric one can also have two functions of shaking and rotating. Using the built-in lithium battery power supply can solve the problem of pulling the power cord when the alloy frame is shaken or rotated. [0003] The telescopic parts at the front and rear ends of the bracket of the existing sofa sinking mechanical stretching device and the rotation of the backrest parts are not located on the same circle, and the center of gravity of the sofa is a certain distance from the bottom plate, the stability...

AI Technical Summary

Problems solved by technology

[0003] The rotation of the telescopic parts at the front and rear ends of the support of the existing sofa sinking mechanical stretching device and the backrest part are not located on the same circle, and the center of gravity of the sofa is a certain distance from the bottom plate, the stability of the sofa is poor, and the existing There is no suitable splicing device installed on the sofa sinking mechanical stretching device bracket, and users cannot adjust the comfort and softness of the sofa according to their own comfort. Therefore, we propose a functional sofa sinking mechanical stretching device bracket
