附图说明
[0014] 图 1为本实用新型结构示意图。
[0015] 图 2为本实用新型另一实施例结构示意图。
[0016] 图 3为本实用新型另一实施例结构示意图。
[0017] 图 4为本实用新型另一实施例结构示意图。
[0018] 其中图中 1.杆体、 2.漂浮部件、 3.环孔。
具体实施方式
[0019] 参考图 1一图 4， 完整的该助泳器由两支完全相同的哑铃形中空塑料制品构成， 既可 两支联用， 也可一支单用。 不管是单用还是联用， 本文中都称之为助泳器。 所谓 *铃形是指 两头粗中间细的一种长条形结构； 中间细的部分方便用手握住， 两头粗的部分有利于产生足 够浮力； 该结构具有很好的稳定性。 每支助泳器中间都带有保护绳 （图中未画出）， 可套在 手上或身上， 以防漂走。 该轻便哑铃形助泳器， 包括中间杆体 1和两端膨大的漂浮部件 2; 漂浮部件 2可以特殊设计与杆体一体成型， 也可由各种形状的密封中空膨大物体 （如塑料饮 料瓶或油瓶等） 构成， 再与杆体可靠连接。
[0020] 该助泳器可粗分为两种类型：
1、 批量生产型： 以无毒轻质塑料吹制而成， 中空， 两头大， 中间细 （图 1 )。 两头大的部分 为漂浮部件， 总容积 4-6升， 每头 2-3升。 容积大小可根据需要增减， 从而产生不同型号的 助泳器， 适合不同人群。 只要助泳器产生的浮力能保证游泳者在水中静止不动时可使脑袋露 出水面呼吸即可。 中间细的部分直径为 2-4cm， 一般为 3cm， 确保游泳者单手即可轻松握 住。 为增加助泳器的强度， 可在助泳器的内腔中增加一些横向和纵向隔板。 考虑到水的浮力 作用， 助泳器的上下部分可以不对称， 一般上大下小， 有利于增强使用的稳定感 （图 3和图 4)。 可设计成开放式的助泳器： 如留有广口瓶螺口并配密封盖， 从而可利用其内腔空间装随 身贵重物品如车钥匙、 手机、 手表等； 可在朝上一侧加设一些固定环孔， 这样可方便装上保 护绳， 也可方便自己升级助泳器 （通过环孔加装适当的矿泉水瓶即可使小号助泳器升级为中 号或大号助泳器）。 另外， 助泳器两端的头部形状可按需要设计， 如可为火箭头形、 梭形、 纺缍形、 鱼形等等， 而助泳器的颜色和图案也可以按需要设计。 按以上描述， 本专利所述助 泳器可粗分为如下类型：
I型为 "上下左右对称型"： 即助泳器的上下部分相对于中轴线对称， 左右部分相对于中线对 称； 这是本专利所述助泳器的基本型。 （图 1 )
II 型为 "上下对称左右不对称型"： 即助泳器的上下部分相对于中轴线对称， 左右部分虽不 说明书
对称但基本形状相同， 这样有利于减小水的阻力。 （图 2)
III型为 "上下不对称左右对称型"： 朝上部分较大， 有利于增加稳定性。 （图 3 )
IV型为 "上下左右不对称型"： 综合 II型和 III型的特点， 既有利于增加稳定性， 又有利于 减小水的阻力。 （图 4)
以上各型均可加设广口瓶螺口并配密封盖， 以使助泳器具有小型贵重物品储存器的功能； 加 设固定环孔使其具有自我升级功能； 两头设计成不同形状并配以不同颜色和图案， 可使其既 具实用功能又具有装饰功能。
[0021] 2、 简易自制型： 将 8-16个空矿泉水瓶 （总容积约 8-16升） 平均分成四组， 每组 2-4 个； 再准备两段约 60cm长的塑料线管 （电工师傅用它来保护电线用的）， 两端钻孔； 用自 制的结实的尼龙绳将矿泉水瓶通过线管上的孔对称地绑在线管的两端， 每端一组瓶子； 线管 中间再系上一保护绳 （使用时套在手腕上， 以防随水漂走）。 这样， 一套简易的游泳辅助器 就制成了。 使用时， 一手拿一个， 游泳者就可以放心大胆地走向深水池或海边泳场了。 作为 加强型， 可在线管的一端加装一可拆卸的密封广口瓶 （可以登山扣实现可拆卸功能） 作为临 时贵重物品储存器。
[0022] 综上所述， 本实用新型助泳器具有如下突出特点：
1、 安全可靠： B亚铃形状， 稳定性好； 中间部分细， 便于抓握； 设有保护绳， 不易滑脱， 防 止漂走； 内腔以纵横交叉隔板支撑， 可增大其受力强度， 从而使本助泳器结实耐用； 本助泳 器可提供足够大的浮力 （如不够时可方便地用空矿泉水瓶自我升级）， 让泳者放心下水。
[0023] 2、 轻巧环保： 本助泳器基本结构采用无毒轻质塑料制成， 可方便地用空矿泉水瓶自 我升级， 价格低廉， 轻巧环保。
[0024] 3、 功能多样： 本助泳器或握于手中， 或夹于腋下， 或踩于脚底， 或漂在身旁， 或夹 在腿间， 使用方式多种多样。 握于手中可辅助自由泳 （一手握一个， 双手轮流划水） 或辅助 练习各种泳姿的腿部动作； 夹于腋下可悬停于水中休息， 随波逐流， 悠哉游哉； 漂在身旁可 作救生备用； 踩于脚底或夹于腿间可增加戏水乐趣。 如加设贵重物品储存格， 还可让泳者省 却物品寄存的麻烦。 设计成不同形状并配以不同颜色和图案既可强化助泳器的功能， 还可让 助泳器在闲置时成为可挂于墙上的装饰品。
