实施例1
高层逃生背包100与传统的安全带相比，更加舒适、安全，并且使用的时候简单，直接将高层逃生背包100通过背包本体200背在背上，即可进行逃生。图1为本实施例提供的高层逃生背包100第一结构示意图；图2为本实施例提供的高层逃生背包100第二结构示意图。请一并参阅图1和图2，本实施例中，高层逃生背包100包括背包本体200和高层逃生缓降器300，背包本体200内设置高层逃生缓降器300。背包本体200背在用户身上，背包本体200的设置使用户身上没有勒缚感，使高层逃生背包100的使用更加舒适。
背包本体200包括背包主体220和背包安全带210，背包安全带210连接于背包主体220，背包主体220内设置高层逃生缓降器300。用户将背包安全带210绑缚在用户身上，背包安全带210的设置使用户身上没有勒缚感，使高层逃生背包100的使用更加舒适。
详细地，请参阅图2，背包安全带210包括连接带211，两根肩部绑带212、两根腰部绑带213和两根裆部绑带214，连接带211具有第一端215和第二端216，每根肩部绑带212的一端与背包主体220连接，另一端设置于第一端215，每根腰部绑带213的一端与背包主体220连接，另一端设置于第一端215，每根裆部绑带214的一端与背包主体220连接，另一端设置于第二端216，且肩部绑带212、腰部绑带213和裆部绑带214从上到下依次设置。
即肩部绑带212用于固定用户肩部，裆部绑带214用于固定用户裆部，腰部绑带213用于固定用户的腰部。用户在高层逃生的时候，由于重力作用拉动背包主体220， 背包主体220会朝上运动到用户的上方，会对用户造成束缚感，并且，造成高层逃生背包100不能安全稳定的下降，所以，背包安全带210具有裆部绑带214，裆部绑带214的设置，可以对用户的裆部进行捆绑，避免高层逃生背包100在使用的过程中朝上运动，用户的使用更加舒适，使高层逃生背包100能够安全稳定的下降。
第一端215设置有卡扣217，第二端216设置有绑扣。即为了使背包主体220均匀承受用户的重力，肩部绑带212与腰部绑带213通过卡扣217与第一端215连接，裆部绑带214通过绑扣与第二端216连接。同时，卡扣217和绑扣的设置还可以调节连接带211的长度，不同身高、体重的用户都能够进行使用。
图3为本实施例提供的高层逃生缓降器300的第一剖视图；图4为本实施例提供的高层逃生缓降器300的第二剖视图；图5为本实施例提供的高层逃生缓降器300的结构示意图。请一并参阅图3-图5，本实施例中，高层逃生缓降器300设置在背包主体220内，包括绳索320、绕绳机构340和变速机构360，绳索320设置于绕绳机构340，通过变速机构360的作用，达到制动的作用。
绕绳机构340包括架体350以及转动设置于架体350的绕绳盘，架体350是高层逃生缓降器300的其他部件安装的基础。请参阅图3，架体350包括相对设置的第一安装板351和第二安装板352以及端盖353，绕绳盘转动设置于第一安装板351和第二安装板352之间，即绕绳盘可以相对于第一安装板351和第二安装板352发生转动，端盖353设置于第二安装板352的远离第一安装板351的一侧，即第一安装板351、第二安装板352以及端盖353依次设置。
第一安装板351可以是背板，第二安装板352可以是面板，端盖353设置在面板的远离背板的一侧，即当用户使用高层逃生缓降器300的时候，靠近背部的第一安装板351为背板，远离背部的第二安装板352为面板，端盖353设置在面板的远离背板的一侧，不会对用户造成挤压，用户能够舒适、安全平稳的下降。
第一安装板351和第二安装板352之间设置多根连接杆，连接杆的两端分别与第一安装板351和第二安装板352连接，增加高层逃生缓降器300的强度，方便对其进行安装。
在第一安装板351和第二安装板352之间进行绕绳盘的设置，绳索320绕设于绕绳盘且一端固定于绕绳盘，另一端与固定件310连接。使用高层逃生缓降器300的时候，将固定件310挂在事先安装的挂钩上进行逃生。
请参阅图3和图4，绕绳盘包括第一挡板342、第二挡板343、中空的绕绳环341和转动轴344，第一挡板342、绕绳环341和第二挡板343均设置在第一安装板351和第二安装板352之间，第一挡板342和第二挡板343分别设置于绕绳环341的两侧， 且第一挡板342与第一安装板351接触，第二挡板343与第二安装板352接触，当绳索320缠绕在绕绳环341上的时候，第一挡板342和第二挡板343阻隔绳索320与第一安装板351和第二安装板352接触，避免绳索320与第一安装板351和第二安装板352之间产生摩擦力。
本实施例中，转动轴344穿过第一挡板342和第二挡板343转动设置于第一安装板351和第二安装板352，且转动轴344设置于绕绳盘内，用户从高层跳下的时候，绳索320不断拉伸出来，使饶设绳索320的绕绳盘不断转动，绕绳盘内的转动轴344发生转动。
第一安装板351和第二安装板352均设置有轴槽，轴槽内设置轴套，两个轴套与转动轴344同轴设置，转动轴344设置在两个轴套内。方便转动轴344的设置，使转动轴344更加容易转动。
变速机构360设置于端盖353内，使整个高层逃生缓降器300的结构更加紧凑、合理，且不会影响高层逃生缓降器300的外观，使高层逃生缓降器300能够安全稳定的下降。
图6为本实施例提供的变速机构360的结构示意图；图7为本实施例提供的端盖353的结构示意图。请参阅图6和图7，本实施例中，变速机构360包括与绕绳盘同步运动的主动轮361和至少一个减速机构370，即主动轮361设置于转动轴344的远离绕绳环341的一端，绕绳环341转动的时候，与绕绳环341连接的第一挡板342和第二挡板343发生转动，则与第一挡板342和第二挡板343连接的转动轴344发生转动，从而使传动轴上的主动轮361转动。
每个减速机构370均包括与主动轮361啮合的从动轮371、设置于从动轮371的连接轴372、摩擦轮373和用于与架体350产生摩擦力的摩擦部374，主动轮361的直径大于从动轮371的直径，摩擦轮373套设于连接轴372的远离从动轮371的一侧，摩擦部374位于摩擦轮373与架体350之间，即摩擦部374位于摩擦轮373与端盖353之间，即从内到外依次设置连接轴372、摩擦轮373、摩擦部374和端盖353。
将固定件310挂在事先安装的挂钩上，用户从高层跳下的时候，绳索320不断拉伸出来，使饶设绳索320的绕绳盘不断转动，从而带动与绕绳盘同步运动的主动轮361转动，由于主动轮361的直径大于从动轮371的直径，与主动轮361啮合的从动轮371就会更加快速的转动，从而使连接轴372快速转动，套设在连接轴372上的摩擦轮373也快速转动，由于离心力的作用，摩擦部374高速转动时，摩擦部374会朝向远离摩擦轮373的径向方向即朝向远离摩擦轮373的方向运动，从而使摩擦部374与端盖353接触，使摩擦部374与端盖353之间产生摩擦力，从而达到减缓下降速度的目的。通 过摩擦部374与端盖353之间的摩擦，用户能够安全稳定地下降，达到高层逃生的目的。
优选地，主动轮361的直径是从动轮371直径的5-8倍，在能够有效安装的基础上，尽可能成倍提高从动轮371的转动速度，以便能够达到制动，使用户能够安全稳定的降落。
请参阅图4和图5，本实施例中，端盖353包括盖板354以及围设在盖板354外周的侧壁板355，侧壁板355的远离盖板354的一侧设置于第二安装板352，摩擦部374沿摩擦轮373的径向方向运动的时候与侧壁板355的内壁摩擦，使摩擦部374与侧壁板355之间产生摩擦力，从而对高层逃生缓降器300进行制动。
本实施例中，侧壁板355上与摩擦部374接触的内壁设置有多条圆环形的槽壁381，即侧壁板355上与摩擦部374接触的内壁不光滑，可以增大摩擦部374与侧壁板355之间的摩擦力；同时，如果不设置圆环形的槽壁381，则摩擦部374长时间与侧壁板355摩擦的时候，则会使摩擦部374表面上由于摩擦而产生的粉末粘在侧壁板355的内壁，使其打滑，所以，在侧壁板355的内壁设置圆环形的槽壁381，由于摩擦而产生的粉末掉入圆环形的槽壁381，不会影响摩擦部374与侧壁板355内壁之间的摩擦，达到匀速下降的目的。
优选地，减速机构370设置有两个，两个减速机构370分别设置于主动轮361的两侧。即从动轮371、摩擦轮373和摩擦部374均设置两个，每个减速机构370的从动轮371、摩擦轮373以及摩擦部374的连接方式相同，两个从动轮371的轴线通过主动轮361的轴线对称设置，进一步提高高层逃生缓降器300的使用安全性，用户在使用高层逃生缓降器300的时候，能够更加安全稳定的下降，避免用户在使用的时候造成恐慌。
与减速机构370配合的是：侧壁板355为两个环形的侧板，一个减速机构370的摩擦部374沿相应的摩擦轮373的径向方向运动的时候与一个侧板的内壁摩擦。则在制动的时候，两个减速机构370的摩擦部374都能够与侧板进行摩擦，进一步提高高层逃生缓降器300制动的效果，进一步提高高层逃生缓降器300的使用安全性，达到更加平稳的下降的效果。
优选地，每个减速机构370的摩擦部374设置有两个，两个摩擦部374间隔设置并通过弹簧378连接。在摩擦轮373高速转动的时候，两个摩擦部374都朝向远离摩擦轮373的方向运动，如果摩擦轮373的转动速度过快，则摩擦部374的离心力则会过大，那么摩擦部374就会与侧壁板355紧密接触，从而容易发生抱死现象，而不能使摩擦部374与侧壁板355之间产生摩擦力，所以，在两个摩擦部374之间设置弹簧 378，即两个摩擦部374之间设置两个弹簧378，每个弹簧378的两端分别连接一个摩擦部374，当摩擦部374与侧壁板355之间的接触过于紧密的时候，由于弹簧378的作用，会对摩擦部374产生拉力，将摩擦部374往回拉，保持摩擦部374与侧壁板355之间位于合适的位置，使其能够相互摩擦，达到制动的目的。
优选地，摩擦轮373的外轮面设置有两个安装槽377，一个摩擦块375分别设置于一个安装槽377内，通过安装槽377的设置，可以限制摩擦部374朝向主动轮361或盖板354的方向运动，使摩擦部374由于离心力的作用下，只能朝向远离摩擦轮373的径向方向运动，与端盖353的侧壁板355的摩擦力更大，缓降效果更好，从而达到安全稳定的下降的目的。
更佳地，摩擦部374包括摩擦块375和摩擦片376，摩擦块375设置于安装槽377内并位于摩擦轮373外，摩擦片376设置于摩擦块375外并位于侧壁板355内。摩擦块375是金属摩擦块，摩擦片376为石棉摩擦片。金属摩擦块的重力较大，在摩擦轮373高速转动的情况下，摩擦块375的离心力更大，摩擦块375朝向远离摩擦轮373的方向运动的效果更好；而石棉摩擦片的设置，可以增大摩擦片376与侧壁板355之间的摩擦力，进一步提高高层逃生缓降器300的下降平稳性，同时，石棉摩擦片有很好的耐高温效果，能够承受由于摩擦力产生的高温，增加摩擦片376的使用寿命。
优选地，在每个摩擦部374的摩擦块375的两端均设置固定环379，弹簧378的两端分别安装在两个摩擦块375的固定环379内，对弹簧378进行安装，也使两个摩擦块375之间的弹力分布更加均匀。本实施例中，摩擦片376和摩擦块375之间通过螺钉连接，也可以通过粘接的方式进行连接，能够将其结合在一起，并且方便拆卸和更换。
图8为本实施例提供的绳索限位装置400的第一结构示意图；图9为本实施例提供的绳索限位装置400的第二结构示意图。请一并参阅图8和图9，本实施例中，绕绳机构340还包括绳索限位装置400，绳索限位装置400的两端均固定于第一安装板351和第二安装板352，绳索限位装置400上设置有限位孔410，绳索320穿过限位孔410与固定件310连接。通过绳索限位装置400的设置来改变绳索320的方向，保证绳索320位于高层逃生缓降器300的中心。
优选地，绳索限位装置400包括滑动辊组件420和绳索挡板430，滑动辊组件420和绳索挡板430的两端均固定于第一安装板351和第二安装板352，绳索挡板430位于滑动辊组件420的上方，绳索挡板430上设置有限位孔410，绳索320依次穿过滑动辊和限位孔410与固定件310连接。通过滑动辊组件420和绳索挡板430的设置来改变绳索320的方向，保证绳索320处于高层逃生缓降器300的中心，同时，滑动辊组件 420的设置，可以减小绳索320与绳索挡板430的摩擦力，避免绳索320磨损，延长高层逃生缓降器300的使用寿命。
更佳地，滑动辊组件420包括两个第一滑动辊421和两个第二滑动辊422，第一滑动辊421设置相对于第二滑动辊422更加靠近行星减速机构370，即在使用高层逃生背包100的时候，第二滑动辊422、第一滑动辊421和行星减速机构370从上到下依次设置，两个第二滑动辊422的两端均设置于绳索挡板430，两个第一滑动辊421的两端分别设置于第一安装板351和第二安装板352，两个第一滑动辊421的轴线与两个第二滑动辊422的轴线相交，绳索320的一端安装在绕绳盘上，另一端先穿过两个第一滑动辊421的中间，再穿过两个第二滑动辊422的中间，从限位孔410穿出，穿过背包主体220与固定件310连接。
通过两个第一滑动辊421和两个第二滑动辊422的设置，优选两个第一滑动辊421的轴线与两个第二滑动辊422的轴线垂直，可以使绳索320在两个第一滑动辊421和两个第二滑动辊422之间穿梭，对绳索320的运动方向具有一定的限制作用，在使用单减速高楼逃生背包的时候，避免绳索320卡死，滑动顺畅，避免绳索320大幅度摆动，减小绳索320受到的摩擦力，增加绳索320的使用寿命，提高高层逃生背包100的使用安全性。
优选地，两个第一滑动辊421中，其分别为一大一小，绳索320从较大的第一滑动辊421上绕设，穿过两个第二滑动辊422之间，进一步避免绳索320的晃动，提高高层逃生背包100的使用安全性与舒适性。
本实施例中，绳索320为钢丝绳，其不会被烧坏，而且强度高，使用寿命长。或其他能够进行高层缓降的绳索320也属于本申请保护的范围。

本申请的高层逃生背包，将背包本体背在用户身上，背包本体的设置使用户身上没有勒缚感，使高层逃生背包的使用更加舒适。架体的设置，可以实现高层逃生缓降器与背包本体的安装，用户从高层跳下的时候，绳索不断从背包本体内拉伸出来，使饶设绳索的绕绳盘不断转动，从而带动与绕绳盘同步运动的主动轮转动，由于主动轮 的直径大于从动轮的直径，与主动轮啮合的从动轮就会更加快速的转动，从而使连接轴快速转动，套设在连接轴上的摩擦轮也快速转动，由于离心力的作用，摩擦部高速转动时，摩擦部会朝向远离摩擦轮的径向方向即朝向远离摩擦轮的方向运动，从而使摩擦部与架体接触，使摩擦部与架体之间产生摩擦力，从而达到减缓下降速度的目的。通过摩擦部与架体之间的摩擦，用户能够安全稳定地下降，达到高层逃生的目的，通过背包本体的设置，高层逃生背包的使用更加舒适。
