Abstract

本实用新型涉及一种牙科轻便椅,其构造特征 是:由坐位架体铰接靠背架体及调节装置组成;可调 节靠背所需高度,靠背架铰接折架板,可折合坐位面 相平,缩小体积,折架板下方连接支撑升降体装置,由 升降体装置带动坐位及靠背同时所需高度,支撑柱装 置由可向上折、收拢与支撑柱周围的支撑腿。
该产品便于折叠收拢、缩小体积、结构简单、搬动 携带轻便,易于存放,使用方便。

Description

本实用新型涉及一种牙科轻便椅,目前国内外牙科轻便椅,通常有可折叠和不可折叠牙科轻便椅。
但现有的牙科轻便椅,其结构是:由坐位下方联接支撑架、或圆体盆,其固定不变,即不能折上收拢。特别是坐位和靠背位置不变,其不能靠背折合,这样不被使用时,需要卸下备部件、折叠体积大,结构复杂。
本实用新型改进上述不足,本实用新型坐位架下方支撑装置的支撑架,采用活动的支撑腿,由固定装置定位,只要调节装置,支撑腿可折上收拢坐位下方。特别是坐位和靠背位置可调,由调节装置改变高度,靠背可折合坐位面相平,缩小占用面积。结构简单,使用方便。下面结合附图及实施例对本实用新型予以详细说明:
图1是本实用新型原理结构示意图。
图2是剖视状态工作原理示意图。
图3是支撑腿折合收拢坐椅架下方示意图。
图4是靠背体折合坐位面相平示意图。
参照附图1至图4所示,由坐椅架1,装置坐位面,坐椅架体1中央下方垂接与固定架2,固定架2设有插栓销3,由插栓销3和支撑柱4相铰接,支撑柱4与固定架体可前后活动,为了使固定架体和支撑柱的前后活动不发生摆动稳定升降,靠背架体的折架板23下方铰接支撑体组件,由支撑套29和可在支撑套内滑行的升降杆27及调节器28组成,支撑套下端与支撑腿12相铰接,支撑升降杆27设有定位凹部,由调节器可调节升降杆可带动支撑柱上端的坐椅架体及靠背架体同时升降高度。支撑柱4下端连接角架板15,角架板可设(三角架或多角架),角架板与6支撑腿相铰接,活动支撑腿带有固定物装置定位,固定物如图1所示,由圆套5,圆平板31,调节器11组成,圆套平板设有缺口32,故支撑腿被使用时只要调节定位器,再把圆套平板转向缺口32后对准支撑腿上部凹口13,圆套平板卡入支撑腿凹部内予以定位,为了稳定圆套平板,则在圆套的定位装置,定位销7同时卡入支撑柱的凹部固定。定位器组件由,卡入凹部定位销7和连接细杆9、细杆压簧8和销套螺盖11组成,定位销穿出螺盖的后端设有拉环10。本实用新型设置4个调节器11、19、22、28机构相同。坐椅架前下方联接踩脚架33,由螺栓固定坐椅架螺孔定位。坐椅架两边固定连接手扶位30。坐椅架后端经铰链16,长插栓销18,铰接靠背架体17,靠背架体设有靠背调节器19,坐椅架连接调节定位板20,由调节定位器19与定位板可调节靠背所需高度。
靠背架上端铰接折架板23,由21螺栓铰接,为了使活动的折架板23定位,靠背架上端,设有折架板调节定位器22,它的作用是调节固定折架板和折合折架板,折架板上端设有螺孔24,装置靠背面,如图1的23所示。折架板的23下方设有支撑体装置,和头部位的定位套26,如图4的26所示,由26的定位套螺栓,可调节头部25的插杆升降固定。本实用新型折叠步骤首先卸下踩脚架33,再由折架板23下方的支撑体的调节器28拉出定位销,脱离升降杆凹部,拉出升降杆27,依次由靠背架体调节器19,拉出定位销,脱离定位板凹部,靠背架体往前压到最高位置,依次由折架板的调节器22,拉出定位销,折架板可向前压,折合与坐位面相平,如图4所示。此后由坐椅架下方的支撑柱圆套5的调节器11,拉出定位销,脱离定位支撑柱凹部后再转动圆套平板,转到缺口32,支撑腿可向上折收拢与支撑柱周围,再往前压,支撑柱4,可折合坐椅架下方,如图3所示。
本实用新型折合体积小,搬运携带轻便,易于存放,使用方便。
