Embodiment Construction

[0025] Such as figure 1 , 2 , shown in 3: a seat frame 1, including a lower base 2, an upper base 3 and a plurality of rotating devices 4 arranged on the upper base or the lower base, the center of the lower base and the center of the upper base Bearings are arranged and connected to each other, so that the upper base can rotate horizontally relative to the lower base without falling off each other, and a plurality of connecting devices 5 are arranged on the upper base. During use, the upper base 3 and the lower base 2 form the main structure of the entire seat frame, and a plurality of rotating devices 4 are passed between the upper base and the lower base, so that the upper base can move relatively on the lower base. As a result, when the lower base is placed on the ground, the rotatable upper base is connected to the sofa seat through the connecting device 5, so that the entire sofa seat can also rotate relative to the lower base. Compared with the base in the prior art, ...

Abstract

The invention relates to a seat frame which comprises a lower base, an upper base and a plurality of rotating devices arranged on the upper base or the lower base, and further comprises at least one rotating device capable of enabling the lower base to horizontally rotate relative to the upper base, and the lower base is connected with the upper base. When the rotating device enables the lower base to horizontally rotate relative to the upper base, the lower base and the upper base do not fall off from each other, and a plurality of connecting devices are arranged on the upper base. Noise generated in the rotating process is eliminated; the size of the seat frame can be adjusted through the telescopic support, installation is easy and convenient, the using effect is good, stability is higher, and popularization is facilitated.

Description

technical field [0001] The invention relates to an accessory used for a sofa and a shifter, specifically a seat frame. Background technique [0002] In the field of functional sofas, the swivel sofa is the most widely used form. The swivel chair seat frame is a common accessory in the office. At present, the swivel sofa generally adopts two connection methods in the market: 1. Connect the sofa body and the base through the rotating shaft, so that Realize the rotation of the sofa; 2. The main body of the sofa is connected through the seat frame, and the steel ball in the seat frame rolls in the disc track to realize the rotation function of the sofa. 3. Detachable seat feet; the rotating sofa can be selected according to the actual style requirements Way. [0003] The existing seat frame has the following defects: [0004] 1. Due to the limited radius of the ball track in the seat frame and the influence of the easy deformation of the balls, the bearing capacity of the seat...
