Description

易于折叠中棒的自动开收多折伞 技术领域
本实用新型涉及一种曰常使用的伞具， 特别是涉及一种自动开收的多折伞。 背景技术
现有的自动开收多折伞通常是通过在中棒内腔设置开伞弹簧提供伸展中棒 的动力， 在伞骨上设置拉簧等结构提供伞骨收折的动力， 一个可被固定在伞头 内或被释放的子弹头以及两端分别与该子弹头和下巢连接的拉线可以拉动下巢 上滑开伞或者释放下巢收伞。 如公告号为 CN2827075 的中国实用新型专利就公 开了一种多折伞的自动开、 收装置， 通过按压伞头上的按钮就能实现开伞或收 折伞骨的目的。 但是现有的这种自动开收伞的中棒内通常只设置一条开伞弹簧 来开伞， 为了能使雨伞能完全打开到位， 需要加强开伞弹簧的强度和圈数， 这 样一来， 在收伞折叠中棒时就非常费力， 因为开伞弹簧圈数越多， 强度越强， 收折中棒所需要的力量就越大， 另外， 开伞弹簧在开伞状态时是从上巢底部一 直伸展至伞头处的， 要将其压缩至收伞状态时一节管体的长度往往需要较大的 力气才能完成， 通常要 6-8 公斤的力， 所以年老体弱者使用起来就会感觉非常 吃力。 实用新型内容
本实用新型针对现有技术的缺陷， 提供一种收伞压缩中棒时只需要较小力 量的自动开收多折伞。
本实用新型的技术方案如下： 一种易于折叠中棒的自动开收多折伞， 包括: 中棒、 伞头、 固定在所述中棒顶部的上巢、 滑动套接于所述中棒的下巢以及安 装在中棒内的开伞弹簧， 所述中棒包括从内至外依次滑动套接的一节内管、 一 节或以上中管和一节外管， 所述内管底部与所述伞头固接， 所述外管顶部与所 述上巢固接。
所述开伞弹簧包括各自独立的第一弹簧和第二弹簧， 所述第二弹簧安装于 所述外管的内腔中， 所述第一弹簧安装于该第二弹簧下方的中棒内腔中。 在中棒的完全折叠状态， 所述外管的顶部高于最外层中管的顶部， 所述第 二弹簧被夹置于最外层中管顶部与所述外管顶部之间的空腔内。
所述外管底部设有一底塞， 所述第二弹簧的底部与该底塞顶部相抵， 所述 第一弹簧顶部与该底塞底部相抵。
所述底塞活动安装于外管内腔。
所述底塞上开设有竖向通孔， 所述上巢底部固定有一条插接于中棒内腔的 胶管， 该胶管穿过所述通孔插入中管内腔， 所述第一弹簧顶部套在该胶管下部 外。
与现有技术相比较， 本实用新型的自动开收伞具有以下有益效果： 中棒内 的开伞弹簧由一段分成上、 下两段， 分别安装在上、 下段管体内， 由此每段开 伞弹簧折叠时的压缩行程大大短于现有的一段式开伞弹簧， 因此收伞时压缩中 棒所需的的力量也大大减少， 由此使用者， 尤其是老人、 小孩等年老体弱者在 曰常使用时更加得心应手。 附图说明
图 1为本实用新型自动开收多折伞在开伞状态时的剖面结构示意图； 图 2为本实用新型自动开收多折伞在收伞状态时的剖面结构示意图； 图 3为本实用新型自动开收多折伞的分解图。 具体实施方式
下面结合附图对本实用新型的实施例作进一步的详细说明。
如图 1 所示， 本实用新型易于折叠中棒的自动开收多折伞包括： 设有收伞 骨弹簧 81的伞骨总成 82、 中棒 1、 伞头 2、 固定在所述中棒 1顶部的上巢 31、 滑动套接于所述中棒 1的下巢 32以及自动开收装置。 所述中棒 1包括从内至外 依次滑动套接的一节内管 11、 一节或以上中管 12和一节外管 1 3 , 所述内管 11 底部与所述伞头 2固接， 所述外管 1 3顶部与所述上巢 31固接。 在本实施例中， 所述自动开收装置包括： 安装在中棒 1内的开伞弹簧、 安装在上巢 31处的上巢 滑轮 83、 设在下巢 32处的下巢滑轮 84、 拉线 85、 固定于上巢 31底部并插入中 棒 1内腔的胶管 86、子弹头 87、安装在伞头 2上的控制按钮 88以及控管 89等。 所述拉线 85 —端连接子弹头 87， 另一端穿过所述胶管 86内腔后绕过上巢滑轮 8 3 , 再绕经下巢滑轮 84， 最后固定在上巢 31上。 收伞压缩中棒 1时， 所述胶管 86将子弹头 87向下推进控管 89内使得子弹头 87被锁定 （如图 2 )。 当按压控 制按钮 88时， 或者被压缩的中棒 1将会被释放并在开伞弹簧的作用下开伞（如 图 1；)， 或者被锁定于控管 89内的子弹头 87将会被释放至中棒 1 内腔中从而伞 骨得以收折起来。 以上结构均为现有技术， 此处不再赘述。
本实用新型的改进之处在于其中的开伞弹簧部件， 下面以三折伞为例加以 详细说明。 如图 1和图 3所示， 所述开伞弹簧由分别独立的第一弹簧 51和第二 弹簧 52组成， 所述第二弹簧 52安装在外管 1 3内腔中， 而第一弹簧 51则安装 于第二弹簧 52下方的中棒 1内腔中。
如图 1所示， 在所述外管 1 3内腔设有一个底塞 6将第一弹簧 51和第二弹 簧 52隔开， 所述第二弹簧 52的底部与该底塞 6顶部相抵， 所述第一弹簧 5 1顶 部与该底塞 6底部相抵。 另外， 该底塞 6是可活动的， 由此， 在开收伞的过程 中， 底塞 6会在上、 下弹簧的作用下沿外管 1 3内腔上下移动， 能更好平衡上、 下两弹簧之间的弹力， 但所述底塞 6的横向宽度大于最外层中管 1 3内壁之间的 宽度， 因此该底塞 6不能向下越过中管 1 3顶部。
如图 2所示， 所述外管 1 3的长度要大于中管 12和内管 1 1的长度， 由此在 中棒 1完全折叠时， 该外管 1 3的顶部高于中管 12的顶部， 所述第二弹簧 52被 夹置于中管 12顶部与外管 1 3顶部之间的空腔内。
所述底塞 6上开设有通孔，所述胶管 86穿过该底塞 6上的通孔插入中管 12 内腔。 所述第一弹簧 5 1顶部套在该胶管 86穿过底塞 6 以下的部分外， 由此对 该第一弹簧 51具有较好的导正作用。
本实用新型的自动开收多折伞还可应用于三折以上的多折伞， 此时， 所述 第二弹簧 52和底塞 6安装在外管 1 3内腔中， 所述第一弹簧 51安装在该底塞 6 以下的管体内腔中。
本实用新型的自动开收多折伞其开伞弹簧分成独立的上下两段， 每段弹簧 所需要的弹力小于现有的一段式开伞弹簧， 而且收伞时每一段弹簧所需压缩的 长度比例大大小于现有的釆用一段式开伞弹簧的压缩长度比例， 由此收伞时压 缩中棒所需的的力量也大大减少， 感觉非常轻巧， 即使是老人小孩也能方便使 用。 以上所述仅为本实用新型的优选实施例而已， 并不用于限制本实用新型， 对于本领域的技术人员来说， 本实用新型可以有各种更改和变化。 凡在本实用 新型的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本 实用新型的保护范围之内。
