有将此类公开技术运用在园艺喷洒装置上， 如台湾专利证号 M329134 的 "伸缩管及具有伸缩管之洒水装置"， 台湾公告编号 393884 的 "伸缩浇 水器之伸缩管结构改良"； 或运用在清洁装置上， 如台湾公告编号 347042 的 "伸缩喷水管之水漏结构"、 台湾公告编号 357604 的 "可伸缩之清洁杆 改良结构"、 台湾公告编号 576177的 "改良型伸缩清洁杆"、 台湾公告编号 582269的 "伸缩清洁杆之构造改良"。
上述各公开结构的共同缺点是：
1.无论伸缩管体在进行长度延伸时， 是利用水压驱动伸展还是手动调 整伸长， 其最后在进行收合时， 都必需完全仰赖双手将两管体或多个管体 予以压合收藏， 才能达至收合的目的。
2.部分公开结构的伸缩管体在进行长度调整时， 不具备可任意长度定 位的功能。
3.部分公开结构的伸缩管体在进行长度调整时， 虽然具有可任意长度 定位的功能。 但是， 此功能必需配合加装偏心定位装置才能达到， 只能增 加装置成本， 以及所沿用的定位方式都是通用模式技术， 亳无创新可言。 发明内容
本发明所要解决的技术问题是提供一种完全利用水压方式， 达到自动 控制水管长度伸展或缩短的伸缩式水管的调整方法及其结构。 本发明还提 供一种以水压控制方式， 使伸缩式水管结构具备无段式长度定位功能。
为解决上述技术问题， 本发明提供一种伸缩式水管的调整方法及其结 构， 其为二段式长形管体， 包括： 一相互套合的内管、 外管， 该内管一端 可供接设喷水头， 另端套合于外管的端部固接有内塞管， 该内塞管于外部 套设有一内塞止水环， 该内塞止水环外部可密贴触于外管的管孔内壁， 以 在内管外壁与外管之管孔间形成一第二外水道， 在内管的管孔与外管的管 孔间形成一第二内水道； 该外管一侧形成有等长且独立的第一水道， 该外 管位在内管套合端固接有一可与第一水道相通的上封盖， 且在上封盖与内 管间设置有一内管止水环； 外管另端固接有一下封盖， 该下封盖具有一容 室， 该容室上端分别设有两独立水道， 分别与外管相通的主水道， 以及与 第一水道相通的副水道； 一水道控制开关， 包括一流道封盖， 供组设于下 封盖内部， 其主要区隔有第一流道可与副水道相连通， 第二流道和第三流 道可与主水道相连通； 一旋转开关， 组设于流道封盖下方， 其内部横向设 有一隔板， 该隔板设有一贯通孔， 可贯通上、 下容置室， 另在隔板上端主 要设有一互通渠道， 且套有一止水环可将互通渠道及贯通孔周围予以框绕， 再将止水环和隔板贴抵于流道封盖底面。
据上述伸缩式水管的结构， 其调整方法为：
将调整旋转开关之贯通孔与流道封盖第一流道对合后， 即可引导水流 自副水道， 经第一水道， 最后进入第二外水道， 再借由水压力量推移与内 管固接成一体的内塞管， 由上而下移动， 便能将内管逐次往外管内部收合, 以达到利用水压驱动使伸缩式水管的长度， 具自动收合的功能。 当调整旋转开关的贯通孔与流道封盖的第二流道对合后， 该第一流道 会被完全封闭， 如此， 原停留在第一水道内的水便无法被排出形成一封存 状态， 即可令内、 外管伸缩长度停留在当下现状； 而另一面水流可由第二 流道， 再自主水道进入外管与内管串接而成之第二内水道排出。
当调整旋转开关的贯通孔与流道封盖的第三流道对合后， 该互通渠道 恰可处在第一流道与第二流道之间形成一串连状态， 如此， 原在第一水道 内的水便能利用互通渠道流向第二流道， 再者， 将互通渠道的口径设计成 小于贯通孔， 实现在第二内水道内部能获得较大水流量， 令第二内水道的 水压大于第一水道水压， 以及借由内管连结喷水头可促使出水压力小于进 水压力原理， 即可利用第二内水道的水压将内管缓慢往外推移， 以达到伸 展伸缩式水管长度的功能。
本发明还提供了第二种伸缩式水管结构， 包括： 内管、 外管套合形成 一串连相通的第一水道和第二外水道， 以及一独立的第二内水道； 一旋转 开关连结于外管一端， 其设有调整导引水流进入第一水道或第二水道的贯 通孔。 该内管套于外管的管孔端部固接有一内塞管， 该内塞管外部与外管 的管孔间设置有一内塞止水环， 使内管外部与外管的管孔间构成第二外水 道， 内管内部与外管的管孔形成第二内水道； 而外管于管孔一侧设有第一 水道， 其在内管套合的端部结合有一将第一水道与第二外水道连通上封盖。 该内塞管下段部设有一外环槽， 该外环槽套有一内塞止水环， 该内塞止水 环外周缘可密贴于外管的管孔内壁。 据此结构， 该调整方法为当调整引导 水流由内塞管底部进入， 水流压力会推移内塞管往上移动， 相对的使内管 往上移动使长型管体呈伸长状态； 当引导水流由内塞管上方进入后， 水流 压力会推移内塞管往下移动， 相对的促使内管向下移动使长形管体呈缩短 状态。 本发明所能达到的有益效果是， 本发明伸缩式水管的调整方法及其结 构， 完全利用水压方式， 达到自动控制水管长度伸展或缩短， 彻底克服了 需要借助双手才能实现伸缩的问题， 并可任意定位水管长度， 适合不同场 合需要。 附图说明

以下， 再配合本发明较佳实施例的图式进一步说明如后， 以期能使熟 悉本发明相关技术人员， 能依本说明书的陈述据以实施： 首先， 请配合参阅图 1、 图 9、 图 10以及图 11所示， 为本发明一种伸 缩式水管的调整方法及其结构较佳实施例分解图， 其包括： 利用二段式套 合的内管 10、 外管 20构成一长形管体， 长形管体内部设有第一水道 200、 第二外水道 300及第二内水道 400,前述第一水道 200和第二外水道 300利 用一上封盖 30相连通； 当引导水流进入第一水道 200后， 可经由上封盖 30 转入第二外水道 300推移内管 10呈收合状态； 当水流引道进入第二内水道 400后， 可配合内管 10出水端水压力小于进水压力， 即可促使内管 10向外 推伸呈长度伸展状态。
继续说明， 本发明该伸缩式水管结构的内管 10, 其一端可供实施接设 有园艺喷水头 100、 或清洁刷头装置（图中未示）、 或农业除虫喷洒头 （图 中未示）等多重实施。 内管 10另一端套于一外管 20的管孔 21, 且内管 10 外径小于外管 20内径， 并在内管 10该端部固接有一内塞管 11, 该内塞管 11下段部设有一外环槽 111, 于外环槽 111套设有一内塞止水环 112, 借由 内塞止水环 112外缘可密贴于外管 20的管孔 21内壁， 即可在内管 10外壁 与外管 20的管孔 21 内壁相对套合位置形成一第二外水道 300 (如图 12所 示）， 另在内管 10的管孔与外管 20的管孔 21 间串连成一第二内水道 400 (如图 12所示）。
一外管 20, 在管孔 21侧边设有一同轴向等长度的第一水道 200, 其上 端固接有一开口向下的上封盖 30, 借由上封盖 30的内部空间 31可将外管 20的管孔 21与第一水道 200 串连相通， 即将第一水道 200和第二外水道 300予以连通， 另在上封盖 30上端设有一上孔 32可供内管 10穿套， 且在 上孔 32与内管 10外周缘间设置有一内管止水环 33,以防止内管 10与上封 盖 30之间产生漏水现象（图 11 ); 前述外管 20于下端部固接有一底部为开 放状态的下封盖 40, 该下封盖 40于上端延伸有独立的主水道 41和副水道 42可分别与外管 20的管孔 21和第一水道 200相连通； 此外， 在外管 20外 部套有一可任意滑动位移的活动式握把 23 , 以方便使用者握持操作。
一水道控制开关 50 , 组接于下封盖 40底部， 其可经由转动一旋转开关 53控制水流导入第一水道 200或第二内水道 400。
通过上述技术方案组成一借由导引水流进入不同水道， 而令套合的内管 10、 外管 20完全利用水压推移力量， 产生长度延伸变化或长度缩短的效果。
继续， 配合其他各零件局部分解图、 零件图、 局部组合图和相对位置 动作示意图， 进行详细说明。
如图 2所示， 本发明于外管 20外部套有握把 23 , 该握把 23可任意进 行位移滑动， 外管 20顶端固接的上封盖 30与其连结成一体， 由图 10及图 11可显示，该外管 20的管孔 21与第一水道 200可经由上封盖 30预留的内 部空间 31形成一种相互连通状态。 再者， 该上封盖 30在上孔 32的底部沿 其周围设有一凸环 34 , 而内管止水环 33上端则设有一与凸环 34相对合的 凹环 331 , 如此， 运用凸、 凹环 34、 331嵌合便能令内管止水环 33具有定 位功能； 另外， 为了令内管 10相对于上封盖 30处在进行位移时， 不至于 受到过大间隙而产生倾角或卡挡等滑移不顺现象， 特在上封盖 30内部相对 于上孔 32下方固接有一限位管 35 , 该限位管 35的管孔 351略大于内管 10 外径， 限位管 35外径小于外管 20的管孔 21 内径， 而限位管 35上端面直 接顶靠在内管止水环 33底面，且在限位管 35上段部两侧设有对称窗孔 352 , 据此， 上封盖 30可借由限位管 35的设立令内管 10上下滑移顺畅。
如图 3、 图 7、 图 8、 图 12和图 18所示， 为下封盖 40及水道控制开关 50分解图， 该下封盖 40结构再配合图 4和图 13所示， 其为一开口向下的 盖体， 盖体上端分别延伸有一主水道 41及一副水道 42 , 该副水道 42形成 于副水道管 421 ,而副水道管 421可密套于第一水道 200 ,且在副水道管 421 外部与第一水道 200内壁间设置有止水环一 422 ; 该主水道 41形成于主水 道管 411 , 而主水道管 411可套合于外管 20的管孔 21 , 且在主水道管 411 外部与前述管孔 21内壁间设置有止水环二 412; 另外， 下封盖 40于内部相 对于副水道 42延伸有一凸环 423, 又于内部轴向设有一轴柱 43, 可供水道 控制开关 50连接。
该水道控制开关 50, 包括： 一流道封盖 51、 一连接管 52和一旋转开 关 53 。
该流道封盖 51, 为一开口向上的盖体， 其设有一轴孔 514, 可供下封 盖 40的轴柱 43枢套连接， 其沿着轴孔 514外围主要依序独立区隔有第一 流道 511、 第二流道 512和第三流道 513, 前述第一、 二、 三流道 511、 512、 513各底部皆设有一贯穿孔 5111、 5121、 5131, 如图 5所示， 且在底部延 伸有一限位柱 515可供套接一连接管 52; 当流道封盖 51组套于下封盖 40 内部后可呈密合状态， 且流道封盖 51顶面与下封盖 40 内部顶面尚预留有 适当高度空间，而第一流道 511上端则可供下封盖 40的凸环 423密套串连， 据此， 如图 10、 图 11、 图 13、 图 14、 图 17、 图 20, 可将第一流道 511、 副水道 42、 第一水道 200、 上封盖 30的内部空间 31和第二外水道 300予 以串连成一独立水道； 如图 12、 图 13至图 16、 图 18和图 19, 该第二、 三 流道 512、 513可直接经由下封盖 40内部与主水道 41相连， 再由主水道 41 与第二内水道 400连接。
该连接管 52, 于内部设有一具有圆孔 5211的横板 521, 使其内部形成 一上管孔 522和一下管孔 523,该上管孔 522可供流道封盖 51的限位柱 515 套接， 并且配合一螺丝 54自下管孔 523, 经圆孔 5211螺锁于限位柱 515预 设的中心孔， 令流道封盖 51与连接管 52组合成一体， 并且在流道封盖 51 底部与连接管 52顶面预留一定空间， 供旋转开关 53组设限位在前述预留 空间处， 并且可进行扭转调整； 该下管孔 523除了设有对称侧孔 524夕卜， 其外部下方更套有一止水环三 525, 另外， 该下管孔 523还配合固接一阶状 定位管 55, 将一水管接头 56设置在阶状定位管 55与连接管 52之间， 以供 连结水源。
该旋转开关 53, 于其内部横向设有一隔板 531, 以区隔成一上容置室 532和一下容置室 533, 该上容置室 532可供下封盖 40下段部容套， 且在 下封盖 40下段部外围与上容置室 532内围间更套置有一止水环四 57,另于 隔板 531设有中心圆孔 5311, 可供流道封盖 51 的限位柱 515穿套， 隔板 531—侧设有一贯通孔 5312, 可供贯通上、 下容置室 532、 533, 另在隔板 531上端主要设有一互通渠道 5313,且套有一止水环 58可将互通渠道 5313 及贯通孔 5312周围予以框绕， 该旋转开关 53的下容置室 533可供连接管 52完全容套， 并且使连接管 52 的止水环三 525外周缘可贴触于下容置室 533内壁； 使当旋转开关 53被组装在流道封盖 51与连接管 52之间呈限位 可转动状态时， 该止水环 58顶面及隔板 531 顶面恰可密贴于流道封盖 51 的底面。
综合上述各零件相关详细位置的组装说明后， 继续说明本发明调整方 法的实施操作共分为以下三种不同状态：
第一种状态： 如图 13、 图 14、 图 17、 图 20所示， 当调整旋转开关 53 的贯通孔 5312与流道封盖 51 的第一流道 511对合时， 可引导水流自副水 道 42、 经第一水道 200、 最后进入第二外水道 300 (如图 10、 图 11所示）， 再借由水压力量推移与内管 10固接成一体的内塞管 11 (如图 12上段部所 示）， 由上而下移动， 便能将内管 10逐次往外管 20内部收合， 以达到利用 水压驱动使伸缩式水管的长度具自动收短的功能。
第二种状态： 如图 13、 图 14、 图 16、 图 19所示， 当调整旋转开关 53 的贯通孔 5312与流道封盖 51的第二流道 512对合后， 该第一流道 511会 被完全封闭， 如此， 原停留在第一水道 200 内的水便无法被排出形成一封 存状态， 即可令内、 外管 10、 20伸缩长度停留在当下现状； 而另一面水流 可由第二流道 512, 再自主水道 41进入外管 20与内管 10串接而成的第二 内水道 400排出。
第三种状态： 如图 13、 图 14、 图 15、 图 18所示， 当调整旋转开关 53 的贯通孔 5312与流道封盖 51的第三流道 513对合后， 该互通渠道 5313恰 可处在第一流道 511与第二流道 512之间形成一串连状态， 如此， 原在第 一水道 200内的水便能利用互通渠道 5313流向第二流道 512, 再者， 特别 将互通渠道 5313 口径设计成小于贯通孔 5312, 以实现此刻在第二内水道 400内部能获得较大水流量， 令第二内水道 400内的水压大于第一水道 200 内水压， 据此， 即可借由第二内水道 400的水压将内管 10缓慢往外推移， 以达到伸展伸缩式水管长度的功能。
再者， 如图 1、 图 3、 图 4和图 6所示， 本发明一种伸缩式水管结构， 其为了使旋转开关 53均能准确的被调整其贯通孔 5312分别与流道封盖 51 的第一、 二、 三流道 511、 512、 513对合， 特在下封盖 40上端外部固接有 一外罩 60, 于外罩 60外部预定处设有一基准标线 61, 另在旋转开关 53上 端外部间隔适当距离设有数个指示标志 534, 可供旋转至与前述基准标线 61位置相对合， 如此， 便能借由不同的指示标志 534与基准标线 61的对合 状态， 快捷的分辨出内、 外管所要呈现的是收合形态或是伸展形态。
另者， 由于本发明的第一流道 511和第三流道 513设在流道封盖 51的 轴孔 514的相对外侧， 故旋转开关 51也在贯通孔 5312分别对合于第一、 三流道 511、 513时， 设计出一定位功能， 其在下封盖 40的外底侧形成有 一凸座 44, 于旋转开关 53的上容置室 532内壁形成有一半凸环 535, 以当 调整贯通孔 5312分别对合于第一、 三流道 511、 513时， 该半凸环 535相 对外侧边可与凸座 44对应外侧边相互抵靠限位。
综上所陈， 仅为本发明之一较佳实施例而已， 并非用来限定本发明实 施之范围。 即凡依本发明申请专利范围所做之均等变化与修饰， 皆为本发 明专利范围所涵盖。
