【技术实现步骤摘要】
一种椅背架
本技术涉及家具制造领域,特别涉及一种用于转椅椅背架。
技术介绍
现有市场上的转椅,一般是通过底盘结构进行相应的倾仰功能,椅背上方受压,椅背往后过程,腰部会处于悬空状态,无法根据人体曲线贴合承托,同时,人体左右转动时,椅背与人体有相对的分离,椅背不能自始至终紧贴人体背部的生理曲线而跟随转动,造成舒适感较差。
技术实现思路
本技术的目的是提供一种能多角度同步转动的椅背架。本技术是这样实现的,一种椅背架,包括:椅背连接角码(1)、椅背框(2)、所述椅背框(2)中下部设置腰部支承件(3),其中;椅背连接角码(1)上端内设若干内突柱(11),顶部设置上通孔(12),内突柱(11)下方设置上螺孔(14);腰部支承件(3)中部设置内凹的连接部(31),连接部(31)中部设置空槽(311),连接部(31)两侧设置下半圆槽(312),连接部(31)上、下方分别对称设置若干内螺孔(313),背部顶端设置若干后突柱(314);椅背盖板(4)上、下方分别对称设置若干外通孔(41),椅背盖板(4)后部两侧设置倒置上半圆槽(42);旋转轴件(5)为扁平T字形,后部两侧设置转轴(51),轴承(52)套接于转轴(51)上,旋转轴件(5)前部设置内通孔(53);所述旋转轴件(5)穿过空槽(311)向外突出,旋转轴件(5)的左、右及上部外边缘与空槽(311)外边缘均留有空隙,所述轴承(52)置于下半圆槽(312)上,所述椅背盖板(4)盖合于连接部(31)上,外螺栓(43)穿过外通孔(41)与内螺孔(313)螺旋紧固,所述上半圆槽(42)与下半圆槽(312)相盖合,若干弹簧(6)两端分 ...
