Description

可调节重心的台球杆
技术领域
本发明涉及一种台球用具， 特别是一种可调节重心的台球杆。 背景技术 .
台球杆是台球运动中非常重要的用具之一， 台球杆的长短、粗细 以及重量、重心对击球的精确度有极大的影响， 因此， 对标准的台球 杆的材质及生产工艺要求非常高。其中， 为了使同样长短、粗细的台 球杆具有不同的重量， 以适应不同使用者的需要， 同时也为了解决木 材的重量不够的问题， 通常的做法是在台球杆的末端部插设一铁芯， 通过该铁芯的重量来决定台球杆的重量。这种台球杆在生产完成后其 重心的位置是固定的， 不可调节。且其重量一般也不可调节， 除非更 换台球杆末端的铁芯才可实现。
可见， 虽然现有的台球杆具有多种多样， 但其重量、重心均为固 定不变、 不可调节的， 因而不能适应使用者的需要。
发明内容
本发明提供一种可调节重心的台球杆，其主要目的在于克服现有 的台球杆的重心位置不可调， 因而不能适于使用者的不同需求的缺 陷。
本发明的另一目的在于克服现有台球杆的重量固定而不可调的 缺陷。
本发明采用如下技术方案：包括杆体，杆体手握端沿杆体长度方 向设有柱形空腔， 该柱形空腔内设有可沿其长度方向移动的加重块， 确 认 本 加重块上设有螺纹孔，螺紋孔中配合有调节螺杆，该调节螺杆靠杆体 末端处设有调节装置。
所述的加重块上设有沿杆体长度方向的滑槽，所述的柱形空腔侧 壁上设有与滑槽配合的滑块。
所述的加重块上设有沿杆体长度方向的滑块，所述的柱形空腔侧 壁上设有与滑块配合的滑槽。
所述调节装置包括套设于杆体末端部的环状体，该环状体内圆周 设有内齿圈，所述调节螺杆末端外圆周设有外齿圈，在该环状体内齿 圈和调节螺杆末端外齿圈之间啮合有若干小齿轮，杆体末端部相应位 置设有可容纳小齿轮的凹槽， 杆体末端面固设有端盖。
所述的杆体包括通过螺杆和螺孔配合连接的前半部分和后半部 分， 所述的柱形空腔设于杆体后半部分的末端。
由上述对本发明结构的描述可知，和现有台球杆相比，本发明具 有如下优点： 首先，本发明可于该台球杆的外部通过旋转调节螺杆外 伸的调节端， 而使调节螺杆上的加重块在螺杆上沿其长度方向移动， 从而可改变台球杆整体的重心位置；其次，本发明可通过在调节螺杆 上增减加重块的数量来调节台球杆整体的重量。
附图说明
图 1为本发明的纵剖面结构示意图；
图 2为图 1中 A-A向剖面结构示意图；
图 3为图 1中 B-B向剖面结构示意图；
图 4为图 1中 C处局部放大图。 具体实施例
本发明的一个具体实施例， 参照图 1至图 4， 该可调节重心的台 球杆包括杆体 100， 杆体 100由前半部分 2和后半部分 1组成， 前半 部分 2的前端设有杆头 6，后端设有一凸出的螺杆 21，后半部分 1的 前端设有一螺紋孔 11， 前半部分 2和后半部分 1通过螺杆 21和螺纹 孔 11的配合组成可拆卸的整根杆体 100。 杆体 100的外形呈角度较 小的锥形。 '
杆体 100的后半部分 1的手握端沿杆体 100的长度方向设有柱形 空腔 10， 该柱形空腔 10通过杆体 100后半部分 1的后端面与外界相 连通， 在柱形空腔 10中设有若干加重块 4， 该加重块 4的数量可根 据需要而定， 该加重块 4的外形与柱形空腔 10的形状相配合， 加重 块 4可在柱形空腔 10内沿长度方向滑动。
加重块 4上设有沿杆体 100长度方向的滑块 41， 柱形空腔 10侧 壁上设有与滑块 41配合的滑槽 13。 也可将滑块 41设于柱形空腔 10 侧壁上， 而将滑槽 13设置于加重块 4上。 其目的在于限制加重块 4 的转动。 '
在加重块 4的中心设有螺纹孔 40， 螺纹孔 40中配合有一调节螺 杆 3， 该调节螺杆 3的中心线与杆体 100的中心线相同， 且其末端部 外圆周设有外齿圈 30， 在杆体 100后半部分 1的末端部外套设有一 环状体 6， 该环状体 6的外圆周与杆体 100后半部分 1的外圆周形成 一个整体式结构，其内圆周设有内齿圈，在该环状体 6内齿圈和调节 螺杆 3末端外齿圈之间啮合有若干小齿轮 7， 杆体 100后半部分 1末 端部相应位置设有可容纳小齿轮 7的凹槽 12， 小齿轮 7通过转轴 71 固定于凹槽 12中， 杆体 100后半部分 1末端面固设有端盖 5。 前述 环状体 6、 小齿轮 7以及调节螺杆 3末端部外齿圈 30构成露于杆体 100外又与之形成整体式结构的调节装置 31。
当使用者需要调节杆体 100的重心时， 只要旋转环状体 6， 即可 通过小齿轮 7带动调节螺杆 3转动，但是调节螺杆 3本身并不相对于 杆体 100发生其长度方向的位移， 当调节螺杆 3.转动时，加重块 4的 滑块 41与柱形通孔 10的滑槽 13配合， 不会发生转动， 因而加重块 4在调节螺杆 3的作用下， 发生杆体 100长度方向上的位移， 从而使 杆体 100的重心发生改变， 以达到调节台球杆重心的目的。
当使用者需要调节杆体 100的重量时，可通过增加或减少调节螺 杆 3上面旋合的加重块 4的数量， 即可改变杆体 100的重量。
上述为本发明的一个具体实施例，但本发明的设计构思并不局限 于此， 本发明的设计构思在于在杆体 100中设置一调节螺杆 3， 在调 节螺杆 3上通过螺纹配合加重块 4， 通过旋转调节螺杆 3使加重块 4 前后移动，从而调节其重心，若通过该构思对本发明进行非实质性的 改动， 如改动加重块 4的形状及柱形空腔 10的形状， 或改动端盖 5 的固接方式， 均应属于本发明的保护范围。
工业实用性
本发明可调节重心的台球杆设计巧妙，各部件生产加工简单、整体 安装方便， 具有良好的工业实用性。
