Abstract

一种拉线拉簧,由拉线和套在拉线上的拉簧构成,拉簧可以滑出拉线之外,而又不会脱离拉线。本实用新型用在自动或半自动晴雨伞上,靠拉簧变形后的恢复力使伞自动收拢,力量均匀轻柔,安全可靠,克服现有中盘弹簧使伞撑开时容易伤人的不足之处。而且本实用新型节省材料,维修更换方便。

Description

拉线拉簧
本实用新型涉及一种拉力弹簧,特别是用于晴雨伞的拉线拉簧。
自动或半自动晴雨伞一般靠弹簧变形后的恢复力将伞自动撑开或收拢。目前普通应用的是一种中盘弹簧,装在伞杆上端,靠其收缩力将伞自动撑开。这种弹簧消耗材料多,伞撑开时力量大,容易伤人,特别是小孩使用,很不安全;而且维修更换比较麻烦。
本实用新型的目的在于克服现有伞用弹簧的不足之处,提供一种节省材料,装在晴雨伞上使用安全,而且维修更换方便的拉线拉簧。
本实用新型的技术方案是:拉线拉簧由拉线和套在拉线上的拉簧构成,拉线的一端有固定圈,另一端有扁头;拉簧朝向拉线扁头的一端有耳钩,拉簧的另一端是直径缩小后的细腰;所述扁头的宽度小于拉簧的内径,而大于细腰的内径。
上述拉线为金属丝,一般采用高碳钢。所述扁头可以是拉线的压扁部位,也可以是拉线的折弯部位。
采用上述技术方案,本实用新型装在伞杆上的滑套和伞面上的撑骨之间,使用时拉簧滑出拉线之外,而又不会脱离;收伞时,拉簧复原,将伞自动收拢,力量均匀轻柔,安全可靠。拉线拉簧可以做得较小,节省材料,维修更换时也很方便。
下面结合附图和实施例进一步说明本实用新型。
附图为本实用新型结构示意图。
本实施例由拉线1和套在拉线上的拉簧2构成,拉线的一端有固定圈3,另一端有扁头6,扁头经冲压后形成。拉簧朝向拉线扁头的一端有耳钩5,另一端是直径缩小后的细腰4。扁头的宽度小于拉簧的内径,而大于细腰的内径,这样拉簧可以滑出拉线之外,而又不会脱离拉线,拉线由70#钢制成,拉簧采用弹簧钢丝,两者均经表面处理,不会生锈,保持光亮。
