Abstract

本实用新型的一种救生用齿条链采用4×4板式链的结构,但每片链片上的一边设计有多个齿,多个齿的周节相加,即为该齿条链的节距,链条上的齿高、周节、压力角等参数均和渐开线齿轮模数规定中的技术参数一致,但齿形的齿顶与齿根处齿与齿之间均采用圆弧形状,便于生产及提高齿的强度。

Description

一种救生用齿条链
(一)技术领域
本实用新型是一种救生用齿条链,属于消防救生部件。 
(二)背景技术
目前世界上轻型火灾逃生器材中的人体承载部件均采用非金属材料的绳类和钢丝绳用于承载人体重量,由于绳类部件的表面呈圆柱状,不易固定物体,仅能在绳的端部固定物体,在火灾救生过程中,绳索类救生器材每次只能解决单人逃生问题,使单位时间内的逃生人数一直不能提升。 
本实用新型的目的是设计一种板式链上的齿与渐开线标准齿轮模数的基本参数相同的齿条链,与一种新型减速器配合,解决火灾群体逃生难题。 
(三)发明内容
为达到上述目的,本实用新型一种救生用齿条链采用4×4板式链的结构,但每片链片上的一边设计有多个齿,多个齿的周节相加,即为该齿条链的节距,链条上的齿高、周节、压力角等参数均和渐开线齿轮模数规定中的技术参数一致,但齿形的齿顶与齿根处齿与齿之间均采用圆弧形状,便于生产及提高齿的强度。 
该齿条链采用了链条式结构,其便于缠绕收放,又采用了齿条的形状,则一条链上完成了多点承载的功能。 
(四)附图说明
图1是本实用新型的一种救生的齿条链结构外形图。 
图1所示的一种救生用齿条链由链接头(1)、外链片(2)、内链片(3)、联接轴(4)组成,内外链片一边有齿(5),内外链片中部开有减速轻孔(6),齿(5)的齿高、周节、压力角等参数均和渐开线齿轮模数规定中的技术参数一致,但齿形的齿顶(a1)与齿根(a2)处齿与齿之间均采用圆弧形状,多个齿的周节相加,即为该齿条链的节距(t)。 

Claims (1)
