如图1所示，本发明实施例一提供一种可拆卸船桨。图1为实施例一的整体结构立体图，所述可拆卸船桨包括主桨杆10，第一可拆卸桨杆20，第二可拆卸桨杆30，桨叶部40，桨把部50，主桨杆10和第一可拆卸桨杆20通过第一连接部60连接、主桨杆10和第二可拆卸桨杆30通过第二连接部70连接。
实施例一
请参考图1及图2，主桨杆10为具有水滴状横截面及一定壁厚的中空杆，第一可拆卸桨杆20、第二可拆卸桨杆30为横截面形状与主桨杆10相同，并具有一定壁厚的中空杆，且第一可拆卸桨杆20、第二可拆卸桨杆30的外壁径向周长稍小于主桨杆10的内壁径向周长，第一可拆卸桨杆20、第二可拆卸桨杆30可进入主桨杆10内并贴合主桨杆10的内壁沿主桨杆10轴向移动，主桨杆10的横截面形状示于图2。
请参考图1、图3至图6，第一连接部60包括用于连接主桨杆10的封闭套环61，用于紧固第一可拆卸桨杆20的紧固装置和用于限位第一可拆卸桨杆20的限位装置。
具体的，封闭套环61固定连接于主桨杆10朝向第一可拆卸桨杆20一端的外沿；
具体的，紧固装置包括非封闭套环62，非封闭套环62至少有一部分与封闭套环61连为一体。
具体的，紧固装置包括位于非封闭套环62开缝处的两侧的第一突出部621和第二突出部622，第一突出部621上和第二突出部622上设置有供螺杆穿过的螺孔。
具体的，第一连接部60包括紧固限位片63；
具体的，紧固装置还包括间隔地设置于紧固限位片63一端的第一凸轮状凸起631、第二凸轮状凸起632，第一凸轮状凸起631和第二凸轮状凸起632之间的间隔被设置为可容纳紧固螺丝64的螺丝头，第一凸轮状突起631、第二凸轮状突起632和紧固螺丝64的螺丝头上均有可供转轴66穿过的转轴孔。
优选的，紧固限位片63远离第一凸轮状突起631和第二凸轮状突起632一端的边沿处设置有凹槽634。
具体的，限位装置包括位于紧固限位片63上远离第一凸轮状突起631和第二凸轮状突起632一端的第一限位块633。
具体的，限位装置还包括位于第一可拆卸桨杆20上朝向主桨杆10一端的第一限位孔21、位于非封闭套环62上的第二限位孔623；
具体的，第一限位孔21和第二限位孔623具有相同的开口形状，第一限位块633被设置为和第一限位孔21、第二限位孔623的开口形状相匹配以进入并牢固地卡住第一限位孔21、第二限位孔623。
图3-图5分别展示了封闭套环61、非封闭套环62、紧固限位片63、紧固螺丝64、螺母65、转轴66的详细结构。
下面结合图6，详细地说明第一连接部60对第一可拆卸桨杆20进行紧固限位的过程：封闭套环61通过胶粘等方式固定连接于主桨杆10朝向第一可拆卸桨杆20一端的外沿处，使得非封闭套环62位于突出主桨杆10外沿的位置；第一可拆卸桨杆20进入非封闭套环62内并进一步进入主桨杆10，适当调整第一可拆卸桨杆20进入主桨杆10的长度，使得第一限位孔21对齐第二限位孔623；转轴66依次穿过第一凸轮状突起631、紧固螺丝64的螺丝头和第二凸轮状突起632上的转轴孔，使得紧固限位片63可以绕转轴66相对于紧固螺丝64转动；将紧固螺丝64的螺杆依次穿过第一突出部621、第二突出部622上的螺孔并套上螺母65，拧动螺母65使得非封闭套环62的开缝逐渐收紧从而实现对第一可拆卸桨杆20的预紧固；此时将紧固限位片63设置有第一限位块633的一端朝向第二限位孔623转动，第一凸轮状突起631和第二凸轮状突起632随着转动向下压第一突出部621，同时由于第一凸轮状突起631、紧固螺丝64、第二凸轮状突起632通过转轴66连接，紧固螺丝64带动螺母65进而带动第二突出部622上提，进一步紧固住第一可拆卸桨杆20；随着紧固限位片63的转动，第一限位块633依次进入第二限位孔623、第一限位孔21并卡住，实现了对第一可拆卸桨杆20的限位。
通过设置主桨杆10、第一可拆卸桨杆20的横截面为水滴状，使得第一可拆卸桨杆20进入主桨杆10后无法转动，从而实现了良好的防转效果；通过所述紧固装置中第一突出部621、第二突出部622、紧固螺丝64和螺母65的配合实现对第一可拆卸桨杆20的预紧固，进一步通过旋转紧 固限位片63使第一凸轮状突起631和第二凸轮状突起632下压第一突出部621并通过转轴66带动螺母64、螺丝65，从而上提第二突出部622，使得非封闭套环62的开缝进一步收紧，从而实现了对第一可拆卸桨杆20良好的紧固；通过第一限位块633进入第二限位孔623和第一限位孔21并卡住，实现了对第一可拆卸桨杆20良好的限位。相对于现有技术中可拆卸船桨的连接装置，第一连接部60可在防止第一可拆卸桨杆20与主桨杆10相对转动的基础上实现良好的紧固限位效果；同时水滴状的桨杆截面形状使得桨杆更加贴合手部的握持，可以实现良好的防滑效果。通过设置凹槽634，可以在进行解除第一连接部60对第一可拆卸桨杆20的紧固限位操作时，便于手指伸进紧固限位片63。
具体的，如图7所示，第二可拆卸桨杆30可进入主桨杆10并调节进入长度，第二连接部70一端固定连接于主桨杆10朝向第二可拆卸桨杆30一端的外沿处，另一端对第二可拆卸桨杆30进行紧固，从而实现了调节桨杆整体长度并对第二可拆卸桨杆30进行防转紧固的效果。
具体的，如图8所示，第一可拆卸桨杆20与桨叶部40可拆卸地连接，第一可拆卸桨杆20朝向桨叶部40的一端设置有限位孔第三限位孔22，桨叶部40朝向第一可拆卸桨杆20的一端具有与第一可拆卸桨杆20的横截面形状相同的横截面形状，其外壁的径向周长稍小于第一可拆卸桨杆20的内壁径向周长，桨叶部40朝向第一可拆卸桨杆20的一端设置有形状与第三限位孔22匹配的第一弹性限位片42，通过下压弹性限位片使其进入第一可拆卸桨杆20，在限位孔位置弹起从而对桨叶部40进行限位，再次下压第一弹性限位片42使其脱离第三限位孔22，可拔出桨叶部40；
如图9所示，第二可拆卸桨杆30与桨把部50可拆卸地连接，第二可拆卸桨杆30朝向桨把部50的一端设置有第四限位孔32，桨把部50朝向第二可拆卸桨杆30的一端具有与第二可拆卸桨杆30的横截面形状相同的横截面形状，其外壁径向周长稍小于第二可拆卸桨杆30的内壁径向周长，桨把部50朝向第二可拆卸桨杆30的一端设置有形状与第四限位孔32匹配的第二弹性限位片52，通过下压第二弹性限位片52使其进入第二可拆卸桨杆30，在第四限位孔32位置弹起从而对桨把部50进行限位，再次下压第二弹性限位片52使其脱离第四限位孔32，可拔出桨把部50。
优选的，第三限位孔22对称设置于第一可拆卸桨杆20上径向曲率最小的两侧，且开口形状相同，第一弹性限位片42对称设置于桨叶部40上径向曲率最小的两侧；
优选的，第四限位孔32对称设置于第二可拆卸桨杆30上径向曲率最小的两侧，且开口形状相同，第二弹性限位片52对称设置于桨把部50上径向曲率最小的两侧。
实施例二
图10给出了本发明实施例二的整体结构立体图。
优选的，第一可拆卸桨杆20和第二可拆卸桨杆30的横截面具有相同的内壁径向周长，第三限位孔22和第四限位孔32具有相同的开口形状，从而在本实施例中，可将桨把部50替换为桨叶部40，使本实施例的可拆卸船桨变为双桨叶形式。
以上对本发明的具体实施方式作了详细介绍，对于本技术领域的技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也属于本发明权利要求的保护范围。
