Sunken mechanical stretching device bracket for functional sofa

Abstract

The invention relates to the technical field of furniture industry and discloses a sunken mechanical stretching device bracket for a functional sofa. The bracket comprises a chassis, the top of the chassis is movably connected with two transverse rods, the two transverse rods are located on the two sides of the circle center of the cross section of the bottom of each transverse rod respectively, the distances between the two transverse rods and the circle center are equal, and the left sides of the upper surfaces of the transverse rods are movably connected with oblique plates. According to the invention, the backrest assembly, the fixing pin, the telescopic assembly, the transverse rod and the supporting frame are matched; when the telescopic assembly and the backrest assembly extend; themoving positions are always positioned on the circumference of the same circle; the telescopic assembly and the backrest assembly are arranged on the left side and the right side of the circumferencerespectively, the balance of the functional sofa is guaranteed, the probability that the sofa touches objects around the sofa in the stretching process is reduced, the heavy object is installed in the chassis, the fourth gravity center is located in the middle of the chassis, and the stability of the functional sofa is improved.

Description

technical field [0001] The invention relates to the technical field of the furniture industry, in particular to a support for a functional sofa sinking type mechanical stretching device. Background technique [0002] Functional sofa refers to a sofa with multiple functions. The most common one is that there are two types of functional sofas, one is manual function stretching, manual can also be equipped with shaking and rotating function sofas, and the other is electric function stretching. The electric one can also have the two functions of shaking and rotating. Using the built-in lithium battery power supply can solve the problem that the alloy frame is pulled on the power cord when shaking or rotating. [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 b...

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
