驅動齒輪(lun)在(zai)不同(tong)的(de)工作平面工作時存在(zai)的(de)四種模式：

第一，常態下(xia)的(de)驅動(dong)(dong)齒(chi)輪(lun)處(chu)于高(gao)(gao)位(wei)工(gong)作(zuo)(zuo)(zuo)面(mian)，撥(bo)桿上端與聯動(dong)(dong)盤上的(de)聯動(dong)(dong)梢傳(chuan)動(dong)(dong)連接，母線(xian)(xian)(xian)輪(lun)通(tong)過單(dan)向(xiang)鎖定裝(zhuang)置實現反轉鎖定；驅動(dong)(dong)齒(chi)輪(lun)帶動(dong)(dong)子線(xian)(xian)(xian)輪(lun)正(zheng)轉使(shi)蚊(wen)帳(zhang)的(de)帳(zhang)身(shen)(shen)升起；帳(zhang)身(shen)(shen)上升到所需高(gao)(gao)度后，驅動(dong)(dong)齒(chi)輪(lun)上的(de)外力(li)撤銷(xiao)，子線(xian)(xian)(xian)輪(lun)受帳(zhang)身(shen)(shen)重力(li)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)產生的(de)反轉作(zuo)(zuo)(zuo)用(yong)(yong)(yong)力(li)經由(you)撥(bo)桿、驅動(dong)(dong)齒(chi)輪(lun)和第一單(dan)向(xiang)軸(zhou)承傳(chuan)導(dao)(dao)給中心軸(zhou)、換(huan)擋橫桿和導(dao)(dao)向(xiang)齒(chi)環；由(you)于定位(wei)壓簧的(de)作(zuo)(zuo)(zuo)用(yong)(yong)(yong)使(shi)換(huan)擋橫桿與導(dao)(dao)向(xiang)齒(chi)環的(de)高(gao)(gao)位(wei)軌道面(mian)之間具(ju)有水(shui)平方向(xiang)的(de)摩(mo)擦阻力(li)，反轉作(zuo)(zuo)(zuo)用(yong)(yong)(yong)力(li)與摩(mo)擦阻力(li)達到平衡狀態從而實現子線(xian)(xian)(xian)輪(lun)的(de)自鎖。

第二，驅(qu)動齒(chi)輪(lun)(lun)反(fan)轉帶動中心軸上的(de)換(huan)擋(dang)橫桿進入高位(wei)工作(zuo)(zuo)(zuo)(zuo)面(mian)(mian)向低位(wei)工作(zuo)(zuo)(zuo)(zuo)面(mian)(mian)過渡面(mian)(mian)時，驅(qu)動齒(chi)輪(lun)(lun)和(he)撥桿隨之(zhi)下降(jiang)，撥桿上端與子線輪(lun)(lun)上的(de)聯動梢分離，子線輪(lun)(lun)可在帳身重(zhong)力(li)的(de)作(zuo)(zuo)(zuo)(zuo)用下反(fan)轉從而(er)使(shi)帳身下降(jiang)；而(er)后撤銷(xiao)驅(qu)動齒(chi)輪(lun)(lun)上的(de)反(fan)轉拉(la)力(li)，換(huan)擋(dang)橫桿在定(ding)位(wei)壓簧作(zuo)(zuo)(zuo)(zuo)用下自(zi)動上行回到高位(wei)工作(zuo)(zuo)(zuo)(zuo)面(mian)(mian)，驅(qu)動齒(chi)輪(lun)(lun)及其上的(de)撥桿與聯動盤重(zhong)新建(jian)立傳(chuan)動連接，從而(er)使(shi)子線輪(lun)(lun)被(bei)重(zhong)新鎖定(ding)。

第三，驅動齒輪切換到低(di)位(wei)工作(zuo)面時，中心軸上的行程簧片推動圓筒母(mu)(mu)軸下(xia)降(jiang)，使下(xia)托盤隨離(li)(li)合(he)盤沿立桿下(xia)降(jiang)，上壓(ya)盤，母(mu)(mu)線(xian)輪、下(xia)托盤之間分離(li)(li)從(cong)而單向(xiang)鎖定裝置釋放(fang)母(mu)(mu)線(xian)輪使其(qi)可在(zai)圓筒母(mu)(mu)軸上自由轉動,重力作(zuo)用下(xia)使帳幔、支架及蚊(wen)帳整體降(jiang)下(xia)；

所(suo)述中(zhong)(zhong)心軸(zhou)(zhou)22以(yi)(yi)及(ji)其上的(de)驅動(dong)(dong)(dong)(dong)齒(chi)輪(lun)(lun)(lun)55、主軸(zhou)(zhou)齒(chi)輪(lun)(lun)(lun)聯動(dong)(dong)(dong)(dong)盆52、撥(bo)桿71、第一單向軸(zhou)(zhou)承(cheng)51和第二(er)固(gu)定軸(zhou)(zhou)承(cheng)53構(gou)成本(ben)發明(ming)的(de)中(zhong)(zhong)軸(zhou)(zhou)系統，驅動(dong)(dong)(dong)(dong)齒(chi)輪(lun)(lun)(lun)5反轉時(shi)換(huan)擋橫桿23與導向齒(chi)環22配合實現中(zhong)(zhong)軸(zhou)(zhou)系統的(de)上下(xia)動(dong)(dong)(dong)(dong)作，從而切(qie)換(huan)驅動(dong)(dong)(dong)(dong)齒(chi)輪(lun)(lun)(lun)5和撥(bo)桿71的(de)工(gong)(gong)作面；換(huan)擋橫桿23在強(qiang)制升降軌(gui)道25的(de)低位(wei)工(gong)(gong)作面、高位(wei)工(gong)(gong)作面、中(zhong)(zhong)位(wei)工(gong)(gong)作面以(yi)(yi)及(ji)過渡平面上駐(zhu)停時(shi)，驅動(dong)(dong)(dong)(dong)齒(chi)輪(lun)(lun)(lun)5在中(zhong)(zhong)心軸(zhou)(zhou)2上具有(you)四種正轉模式：

第一(yi)，常(chang)態下的驅動(dong)齒(chi)輪(lun)(lun)5處于(yu)高位工作面，撥桿71上端(duan)與聯(lian)動(dong)盤(pan)44的聯(lian)動(dong)梢(shao)45傳動(dong)連(lian)接，驅動(dong)齒(chi)輪(lun)(lun)5依次(ci)帶動(dong)撥桿71、聯(lian)動(dong)梢(shao)45、聯(lian)動(dong)盤(pan)44、圓筒子軸42以及若干子線(xian)輪(lun)(lun)43正(zheng)轉，使(shi)蚊帳81的各個連(lian)接點同時上升到所需高度。

第二，換(huan)擋橫桿(gan)(gan)23從高位工作(zuo)面向(xiang)低(di)位工作(zuo)面過渡時，驅(qu)動齒(chi)輪5和撥(bo)桿(gan)(gan)71下降(jiang)，此(ci)過程(cheng)中(zhong)撥(bo)桿(gan)(gan)71與(yu)聯(lian)動梢45分離，子線輪43失去約束力(li)，在重(zhong)力(li)拉(la)動下旋轉，蚊帳帳身隨(sui)牽引繩下降(jiang)；當(dang)作(zuo)用力(li)轍(che)消時，換(huan)擋橫桿(gan)(gan)23在過渡斜面上受定位壓簧24的壓力(li)自動滑落(luo)回到高位工作(zuo)面，子線輪43重(zhong)新被鎖(suo)定。

第三，驅動(dong)齒輪5切換(huan)到低位工作面(mian)時，中心軸2上(shang)的行程簧片(pian)29推(tui)動(dong)圓筒母(mu)軸32下(xia)降，使下(xia)托盤(pan)64隨(sui)離合盤(pan)62沿立桿13下(xia)滑脫離上(shang)壓盤(pan)33，母(mu)線輪31可(ke)自(zi)由轉動(dong)從而在重力作用(yong)下(xia)使帳幔支架82降下(xia)。

第(di)四，換擋橫桿23處于中位工作(zuo)面時(shi)，行程簧片29釋放圓(yuan)筒(tong)母(mu)軸(zhou)(zhou)32使離合(he)盤62及其上(shang)的(de)(de)(de)下托盤64與上(shang)壓盤33配合(he)夾持母(mu)線輪31，撥(bo)桿71下端與通過(guo)活(huo)動(dong)(dong)(dong)(dong)(dong)擋臂72與上(shang)壓盤33上(shang)的(de)(de)(de)母(mu)盆傳動(dong)(dong)(dong)(dong)(dong)梢35傳動(dong)(dong)(dong)(dong)(dong)連(lian)接，驅動(dong)(dong)(dong)(dong)(dong)齒(chi)輪5正轉帶動(dong)(dong)(dong)(dong)(dong)母(mu)線輪31進而提(ti)升帳幔支架82到所需(xu)高(gao)度；撤銷對(dui)驅動(dong)(dong)(dong)(dong)(dong)齒(chi)輪5的(de)(de)(de)拉(la)力(li)后，圓(yuan)筒(tong)母(mu)軸(zhou)(zhou)32通過(guo)第(di)二(er)單(dan)向軸(zhou)(zhou)承61的(de)(de)(de)單(dan)向轉動(dong)(dong)(dong)(dong)(dong)性，使母(mu)輪組件3回到自鎖狀態(tai)。

本發明通過上(shang)述結構的有機結合(he)，實現(xian)蚊帳(zhang)81與帳(zhang)幔支架82的升降調節和任意高度駐(zhu)停，方便(bian)用戶對蚊帳(zhang)81的靈活使用，提(ti)高拆卸(xie)清洗便(bian)利性和使用安全性，整體結構簡潔(jie)穩定、應用范圍廣。
