本发明涉及户外用具技术领域, 更具体地说, 涉及一种搁杆叉, 还涉 及一种搁杆叉头基座。 背景技术
搁杆叉是一种钓鱼用具, 主要用于固定钓鱼竿。 搁杆叉上安装有配套 的搁杆叉头, 以防止钓鱼竿在搁杆叉上滑动。 如图 1所示, 现有的搁杆叉 包括搁杆叉头 01、 定向环 02、 搁杆叉头基座 03和支架(图中未示出)。 其 中, 搁杆叉头 01的一端具有 U型叉头 011 , 另一端设置有螺纹段 012; 定 向环 02上设置有与螺纹段 012相匹配的定向螺纹孔 021 ;搁杆叉头基座 03 上设置有与支架配合的安装孔 032和与螺纹段 012匹配的内螺纹孔 031。
在使用搁杆叉时, 通过安装孔 032将搁杆叉头基座 03安装到支架上, 在将定向环 02套设在螺纹段 012上后, 再将搁杆叉头 01旋入搁杆叉头基 座 03中。 将支架固定到地面上后, 可以通过旋转搁杆叉头 01和定向环 02 调节搁杆叉头 01的方向, 其方法为: 旋转定向环 02, 使定向环 02与搁杆 叉头基座 03脱离接触; 再旋转搁杆叉头 01 , 使搁杆叉头 01的方向与所需 要的方向一致;最后旋转定向环 02,使定向环 02与搁杆叉头基座 03贴紧, 利用定向环 02与搁杆叉头基座 03之间的预紧力使搁杆叉头 01不能旋转。
由以上所述可知, 现有的搁杆叉通过搁杆叉头 01、 定向环 02和搁杆 叉头基座 03之间的螺纹配合调节方向,其使用过程中需要繁瑣的旋开、旋 紧螺纹, 操作繁瑣, 不能快速定位方向。 其次, 通过预紧力和螺纹配合的 定向方式稳定性差, 在搁杆叉头发生意外旋转时, 现有的定位方式容易失 效。 因此, 如何提供一种操作筒便的搁杆叉, 能够实现搁杆叉头的快速定 向, 成为本领域技术人员亟需解决的技术问题。 发明内容
有鉴于此, 本发明提供一种搁杆叉, 其操作筒便, 能够实现搁杆叉头 的快速定向。
为实现上述目的, 本发明提供如下技术方案:

为使本发明的上述目的、 特征和优点能够更加明显易懂, 下面结合附 图对本发明的具体实施方式做详细的说明。
在下面的描述中阐述了很多具体细节以便于充分理解本发明, 但是本 发明还可以采用其他不同于在此描述的其它方式来实施, 本领域技术人员 可以在不违背本发明内涵的情况下做类似推广, 因此本发明不受下面公开 的具体实施例的限制。
本发明实施例公开了一种搁杆叉, 其操作筒便, 能够实现搁杆叉头的 快速定向。
如图 1所示, 本发明实施例所提供的搁杆叉包括搁杆叉头 1和搁杆叉 头基座 2。
搁杆叉头 1的一端为类似于现有搁杆叉头的 U型叉头, 而另一端为横 截面为轴对称多边形的连接柱 11 , 同时, 连接柱 11上设置有定位槽 12, 优选地,该定位槽 12为设置在连接柱中部的环形定位槽。搁杆叉头 1通过 连接杆 11与搁杆叉头基座相连。
搁杆叉头基座 2又包括基座本体 21、 定位板 22和弹性复位件 23。 其 中, 基座本体 21上设置有连接孔 211和定位板安装槽 212, 连接孔 211的 横截面与连接柱 11的横截面相同,因此连接柱 11能够插入连接孔 211中; 定位板安装槽 212与连接孔 211相连通, 优选地, 定位板安装槽 212垂直 于连接孔 211的轴线。 定位板 22设置在定位板安装槽 212中, 定位板 22 上设置有与连接柱 11相匹配的定位孔 221 ,本领域技术人员可以理解的是, 需要首先将定位板 22插入定位板安装槽 212之后, 再将连接柱 11插入连 接孔 211中, 这样, 在连接柱 11的阻挡下, 定位板不会滑出。 弹性复位件 23设置在基座本体 21与定位板 22之间, 本领域技术人员可以理解的是, 在弹性复位件 23的作用下, 定位板 22会卡在定位槽 12中, 因此, 搁杆叉 头 1不能从搁杆叉头基座 2中拔出。
作为公知, 搁杆叉还包括支架等其它零部件, 由于其与本发明的发明 点关系不大, 此处不再赘述。
在首次使用本发明所提供的搁杆叉时, 只需向内按下定位板 22, 将搁 杆叉头 1插入搁杆叉头基座 2后, 再松开定位板 22, 即可完成搁杆叉头 1 的定向; 而在使用本发明所提供搁杆叉时,如果需要改变搁杆叉头的方向, 只需按下定位板 22, 将搁杆叉头 1从搁杆叉头基座 2中拔出, 再次选择合 适的角度将搁杆叉头 1插入搁杆叉头基座 2, 最后松开定位板 22, 即可完 成对搁杆叉头 1方向的调整。
由以上可知, 与现有的采用螺纹连接搁杆叉头与搁杆叉头基座的搁杆 叉相比, 本发明所提供的搁杆叉操作筒便, 搁杆叉头定位迅速。
具体的,在上述实施例所提供的搁杆叉中,连接柱 11的横截面为正六 边形, 而连接孔 211为具有相同正六边形孔的连接孔, 如图 3所示。
通过实验发现, 当连接杆采用正六边形横截面时, 搁杆叉头能够 3个 彼此呈 60° 夹角定位方向, 基本满足了搁杆叉的使用需求, 同时, 此时的 连接杆 11能够具有良好的强度和韧性。
本领域技术人员可以想到的是, 连接杆的横截面还可以为正五边形、 正七边形或正八边形等具有轴对称性质的形状; 连接杆在上述实施例中为 横截面面积不变正多边棱柱, 而在实际情况中, 连接杆还可以为横截面为 轴对称截面的棱锥。
进一步的, 在上述实施例所提供的搁杆叉的基础上, 本发明另一实施 例所提供的搁杆叉还包括限位销 24。基座本体 21上设置有限位孔 213 , 限 位销 24设置在限位孔 213中。 同时, 定位板 22上设置有限位槽 222。 将 定位板 22插入定位板安装槽 212中, 在将限位销 24插入限位孔 213中, 在弹性复位件 23的作用下, 定位板 22通过限位槽 222卡在限位销 24上, 不能向外弹出。
与上述实施例所提供的搁杆叉相比, 本实施例所提供的搁杆叉通过设 置限位销 24、 限位孔 213和限位槽 222, 使得在不插入搁杆叉头时定位板 22也不会从其安装位置弹出, 避免了在拆、 装搁杆叉头时定位板 22意外 遗失的情况。
在上述实施例所提供的搁杆叉中, 使用者在操作过程中需要直接用手 指按压定位板 22, 由于定位板 22厚度较薄, 作用在使用者手指上的压强 较大, 容易对手指造成伤害。 因此, 在上述实施例的基础上, 本发明另一 实施例所提供的搁杆叉还包括按键 25。
如图 5所示, 按键 25 的一端为按键面, 另一端设置有用于与定位板 22相连的连接槽 251。 同时, 基座本体 21上设置有与定位板安装槽 212 相连通的按键孔 214, 定位板 22通过连接槽 251与按键 25可拆卸地固定 相连, 二者共同设置在按键孔 214中; 弹性复位件 23的一端与按键 25接 触, 另一端与基座本体 21相抵定位。
有上述可知, 通过设置按键 25 , 增大了使用者按压定位板 22时的受 力面积, 减小了作用于手指上的压强, 避免了手指受到伤害的可能。
本领域技术人员可以理解的是,在本实施例的附图中,按键 25按键面 为外凸的弧形表面, 按键面的轮廓为带有圆角的三角形, 但是, 在生产中, 可以根据实际的需求, 将按键面设计为不同的形状, 如按键面为中心内凹 的弧形表面, 其轮廓为具有圆角的矩形等。
优选地, 在上述实施例中, 按键 25与定位板 22为一体式结构, 即二 者为同时具有较大按键面和定位板结构的定位按键 26, 如图 6所示。
具体的,在上述实施例所提供的搁杆叉中,弹性复位件 23为压缩弹簧。 压缩弹簧为常见的弹性元件, 其结构筒单、 可靠, 同时具有完善的制造标 准, 容易采购, 成本低廉。
本发明实施例还提供了一种搁杆叉头基座, 具体的, 该搁杆叉头基座 即为上述实施例中的搁杆叉头基座 2, 其结构与前文所述完全相同, 在此 不再赘述。
为了使现有的搁杆叉头也能应用到本发明实施例所提供的搁杆叉头基 座中, 本实施例所提供的搁杆叉头基座还包括种转换杆 3。
如图 7所示, 转换杆 3的一端为与连接孔 211相匹配的转换杆连接柱 31 , 其另一端为能够与现有的搁杆叉头螺纹段相匹配的内螺纹孔 32。
在使用本发明实施例所提供的搁杆叉头基座时, 将现有搁杆叉头 011 的螺纹段旋入转换杆 3的内螺纹孔 32中,在将二者的组合体嵌入搁杆叉头 基座 2中, 如图 8和图 9所示, 图 8为现有搁杆叉头 011、 转换杆 3和搁 杆叉头基座 2的连接关系示意图, 图 9为三者完成连接后的结构示意图。 可知, 当现有的搁杆叉头 011与转换杆 3组合后, 其具有前文所述的搁杆 叉头的结构特点, 因此二者的组合体能够与搁杆叉头基座 2配合使用。
本说明书中各个实施例采用递进的方式描述, 每个实施例重点说明的 都是与其他实施例的不同之处, 各个实施例之间相同相似部分互相参见即 可。
虽然本发明已以较佳实施例披露如上, 然而并非用以限定本发明。 任 何熟悉本领域的技术人员, 在不脱离本发明技术方案范围情况下, 都可利 用上述揭示的方法和技术内容对本发明技术方案作出许多可能的变动和修 饰, 或修改为等同变化的等效实施例。 因此, 凡是未脱离本发明技术方案 变化及修饰, 均仍属于本发明技术方案保护的范围内。
