Abstract

一种用于机动车和非机动车的手动线型制动闸, 能够克服线型制动闸闸线容易在铅封根部折断,造成 制动失灵,给人身带来危险的缺陷。该闸线(3)绕在 一段以固定转动轴(4)轴心为圆心所做的同心圆弧面 上,当闸柄牵引闸线运动时,受力方向不变,从而保证 闸线不致折断。

Description

本实用新型属机动和非机动车辆的手动线型制动闸装置。
手动线型制动闸的工作原理是由闸柄牵引闸线未端的铅封,绕固定转动轴转动,通过闸线的伸缩来完成制动目的。但由于存在着铅封与固定转动轴的相对位置的问题,使得铅封在绕固定转动轴转动时,其转动半径在不断变化,致使闸线在铅封根部反复受折,最终被折断,给人身带来危险和伤害。
本实用新型的目的是提供一种改进的手动线型制动闸,它能有效地防止闸线被折断。
本实用新型的原理为,使闸线绕在一段可转动的同心园弧上,闸线始终受一固定半径牵引,受力方向在同一直线上,从而保证闸线不受折,不断裂。
本实用新型的具体结构由以下实施例及附图给出。
附图为本实用新型提出的耐久性线型制动闸的平面图。
该闸主要包括闸柄②、固定转动轴④、闸线③、铅封①组成。图中⑤为闸线与园弧相切的切点。
以固定转动轴④的轴心为园心,以大于园心至切点⑤之间2mm的距离为半径做一段园心角大于90°的园弧面,并在此园弧面上开一段深宽各2mm的槽来容纳闸线③,闸线③沿此槽绕在一段以固定转动轴④轴心为园心所做的同心园弧面上,当闸柄②牵引闸线③运动时,闸线③受一固定半径牵引,闸线③越过切点⑤之后,穿过闸柄②、铅封①被固定于闸柄②背部,这样闸线受力方向始终在同一直线上,不会被折断。

Claims (1)

1、一种耐久性线型制动闸,该闸有一个闸柄②,与其相连的闸线③被铅封①牵引,穿过闸柄②被固定在闸柄背部,闸柄②被固定转动轴④固定住,其特征在于闸线③绕在一段以固定转动轴④轴心为园心所做的同心园弧面上,当闸柄②牵引闸线③运动时,闸线③受一固定半径牵引。
