Description

伸缩警棍 技术领域
本发明涉及警用装备技术领域，具体而言，涉及一种伸缩警棍。
背景技术
伸缩警棍的棍体由多节管体组成，现有的一些伸缩警棍的管体并分别与2根弹簧相连，手柄后端有一块磁铁，用以固定棍体。使用时，按压手柄钮释放弹簧，棍体即在弹簧的作用下伸出；不用时，将棍体头部向下，在硬物上轻轻一磕，棍体即可收回。该警棍使用灵活方便，便于携带。
然而，现有的伸缩警棍伸出后受阻力即缩回，稳定性差，且伸缩过程中操作不流畅，解锁不方便。
发明内容
本发明的主要目的在于提供一种伸缩警棍，以解决现有技术中的伸缩警棍稳定性差，解锁不方便的问题。
为了实现上述目的，本发明提供了一种伸缩警棍，包括：多根管体，多根管体依次嵌套设置，在相邻两根管体之中，位于内侧的管体可沿位于外侧的管体的轴线方向伸缩，位于外侧的管体的第一端的内壁上设置有锁定凹槽；叶片凸轮锁定组件，叶片凸轮锁定组件包括座套、叶片凸轮块、扭簧以及固定机构，其中，座套固定连接在位于内侧的管体的第一端；多块叶片凸轮块沿同一周向布置在座套上，扭簧的两个伸出端分别抵顶在座套和叶片凸轮块上以使多块叶片凸轮块向远离座套的中心轴线的方向扩张，当位于内侧的管体的第一端伸出至位于外侧的管体的第一端时，叶片凸轮块受扭簧施加的作用力自动卡设在锁定凹槽内；解锁结构，解锁结构固定安装在多根管体的最外侧的管体内，解锁结构受外力作用驱动多块叶片凸轮块向靠近座套的中心轴线的方向收缩以对叶片凸轮锁定组件解锁。
进一步地，固定机构包括：定位板，定位板安装在叶片凸轮块的远离座套的一侧；螺丝轴，螺丝轴穿过定位板和叶片凸轮块连接在座套上。
进一步地，叶片凸轮锁定组件还包括润滑片，润滑片安装在叶片凸轮块和定位板之间。
进一步地，，锁定凹槽内设置有环形铁圈。
进一步地，座套上设置有第一定位孔，叶片凸轮块上设置有与第一定位孔对应的第二定位孔，扭簧套设在螺丝轴上，扭簧的两端分别位于第一定位孔和第二定位孔内。
进一步地，座套上设置螺柱段，位于内侧的管体的第一端设置有螺纹孔。
进一步地，叶片凸轮块为三块，三块叶片凸轮块的凸轮部位于座套的中部，解锁结构拨动凸轮部以使三块叶片凸轮块向靠近座套的中心轴线的方向收缩而对叶片凸轮锁定组件解锁。
进一步地，解锁结构为顶针，叶片凸轮锁定组件上设置有让位孔，顶针穿过让位孔以驱动三块叶片凸轮块向靠近座套的中心轴线的方向收缩。
进一步地，位于最外侧的管体的端部设置有用于驱动解锁结构运动的开关按钮。
应用本发明的技术方案，本发明中通过设置叶片凸轮锁定组件以及解锁结构，便于将伸缩警棍的位于内侧的管体锁定在位于外侧的管体的第一端，保持伸缩警棍的伸出状态，当需要将伸缩警棍收缩时，只要通过解锁结构对叶片凸轮锁定组件进行解锁，便能够使得位于内侧的管体缩回至位于外侧的管体内，操作简单快捷，稳定性好，便于警务人员使用。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施方式例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
参见图1至8所示，根据本发明的实施例，提供了一种伸缩警棍，该伸缩警棍包括多根管体10、叶片凸轮锁定组件20以及解锁结构30。
其中，多根管体10依次嵌套设置，在相邻两根管体10之中，位于内侧的管体10可沿位于外侧的管体10的轴线方向伸缩，位于外侧的管体10的第一端的内壁上设置有锁定凹槽11；叶片凸轮锁定组件20固定安装在相邻两根管体10之中位于内侧的管体10的第一端，当位于内侧的管体10的第一端伸出至位于外侧的管体10的第一端时，叶片凸轮锁定组件20自动卡设在锁定凹槽11内，进而将位于内侧的的管体10锁定在位于外侧的管体10的第一端；解锁结构30固定安装在多根管体10的最外侧的管体10内，解锁结构30受外力作用驱动多块叶片凸轮块22向靠近座套21的中心轴线的方向收缩以对叶片凸轮锁定组件20解锁，通过解锁结构30对叶片凸轮锁定组件20解锁后，位于内侧的管体10可以沿位于外侧的管体10的轴线方向***，此时，只需要对位于内侧的管体10施加力的作用，便可以使得位于内侧的管体10缩回至位于外侧的管体10内。
根据上述的结构可以知道，本实施例中通过设置叶片凸轮锁定组件20以及解锁结构30，便于将伸缩警棍的位于内侧的管体10锁定在位于外侧的管体10的第一端，保持伸缩警棍的伸出状态，当需要将伸缩警棍收缩时，只要通过解锁结构30对叶片凸轮锁定组件20进行解锁，便能够使得位于内侧的管体10缩回至位于外侧的管体10内，操作简单快捷，稳定性好，便于警务人员使用。
结合图3和图4所示，本实施例中的叶片凸轮锁定组件20包括座套21、叶片凸轮块22、扭簧26以及固定机构23。
其中，座套21固定连接在位于内侧的管体10的第一端；多块叶片凸轮块22沿同一周向布置在座套21上；扭簧26安装在座套21和叶片凸轮块22之间以使多块叶片凸轮块22向远离座套21的中心轴线的方向扩张，当位于内侧的管体10的第一端伸出至位于外侧的管体10的第一端时，叶片凸轮块22受扭簧26施加的作用力自动卡设在锁定凹槽11内；固定机构23用于将叶片凸轮块22固定在座套21上。
当将位于内侧的管体10拉伸至位于外侧的管体10的第一端时，叶片凸轮锁定组件20的扭簧26会使得多块叶片凸轮块22向远离座套21的中心轴线的方向扩张，进而将叶片凸轮块22卡设在锁定凹槽11内，使得位于内侧的管体10无法相对位于外侧的管体10运动，进而实现对伸缩警棍的锁定。
优选地，本实施例中的固定机构23包括定位板231和螺丝轴232，定位板231安装在叶片凸轮块22的远离座套21的一侧；螺丝轴232穿过定位板231和叶片凸轮块22并连接在座套21上，进而将叶片凸轮块22固定在座套21上，结构简单，稳定性好。
当然，在本发明的其他实施例中，还可以不设置定位板231，而直接采用螺丝轴232将叶片凸轮块22固定在座套21上，只要是在本发明的构思下的其他变形方式，均在本发明的保护范围之内。
本实施例中通过设置定位板231，能够将多块叶片凸轮块22限定在定位板231和座套21之间，防止叶片凸轮块22发生偏移。
为了保证叶片凸轮块22的运动顺畅性，本实施例中的叶片凸轮锁定组件20还包括润滑片24，该润滑片24安装在叶片凸轮块22和定位板231之间，保证叶片凸轮块22能够在座套21和定位板231之间***。优选地，本实施例中的润滑片24为铜片，当然，在本发明的其他实施例中，还可以将润滑片24设置为其他表面光滑的垫片结构，只要是在本发明的构思下的其他变形方式，均在本发明的保护范围之内。
优选地，本实施例中的管体10为铝管，锁定凹槽11内设置有环形铁圈(图中未示出)，通过环形铁圈的作用，能够避免锁定凹槽11的内端面由于叶片凸轮块22高压力下冲击造成的磨损或毛刺，保护警棍的伸缩功能。
本实施例中的座套21上设置有第一定位孔211，叶片凸轮块22上设置有与第一定位孔211对应的第二定位孔221，扭簧26套设在螺丝轴232上，且扭簧26的两端分别位于第一定位孔211和第二定位孔221内，扭簧26的两个伸出端分别抵顶在座套21设叶片凸轮块22上，便于对叶片凸轮块22施加一个向外的扭力的作用而使多块叶片凸轮块22向远离座套21的中心轴线的方向扩张而锁定在锁定凹槽11内。
再次结合图1至图8所示，本实施例中的叶片凸轮块22为三块，三块叶片凸轮块22的凸轮部位于座套21的中部，解锁结构30拨动凸轮部以使三块叶片凸轮块22向靠近座套21 的中心轴线的方向收缩而对叶片凸轮锁定组件20解锁，当叶片凸轮块22向靠近座套21的中心轴线的方向收缩时，只需要对位于内侧的管体10施加力的作用，便可以使得位于内侧的管体10缩回至位于外侧的管体10内。
本实施例中的解锁结构30为顶针，叶片凸轮锁定组件20上设置有让位孔25，顶针穿过让位孔25以驱动三块叶片凸轮块22向内收缩，结构简单，便于实现。
为了便于对解锁结构30进行控制，本实施例中的位于最外侧的管体10的端部设置有用于驱动解锁结构30运动的开关按钮40。该开关按钮40包括设置在位于外侧的管体10的端部的复位弹簧和与顶针固定在一起的按钮，按压按钮可以驱动顶针穿过让位孔25以驱动块叶片凸轮块22向内收缩，在复位弹簧的作用下，便于使得顶针复位，结构简单，便于控制。
本实施例中的座套21上设置螺柱段212，位于内侧的管体10的第一端设置有螺纹孔，通过螺柱段212和螺纹孔的配合作用，便于将座套21固定在管体10上。当然，在本发明的其他实施例中，还可以采用其他紧固件，例如螺钉、铆钉等结构将座套21固定在管体10上，只要是在本发明的构思下的其他变形方式，均在本发明的保护范围之内。
优选地，本实施例中的管体10为三根，当伸缩警棍包括三根管体10时，其包括第一管体，套设于第一管体内的第二管体以及套设于第二管体内的第三管体。其中，第一管体以及第二管体的内壁均设置有一锁定凹槽11；第一管体头部设有开关按钮40，该开关按钮40上连接有一顶针；在第二管体以及第三管体的末端设有一组能旋转伸缩的叶片凸轮锁定组件20，叶片凸轮块22伸出时能收容于锁定凹槽11内。叶片凸轮锁定组件20内设有扭簧26，使叶片凸轮块22始终有一个向外的扭力，使警棍伸出时在锁定凹槽11内。锁定凹槽11内设有一个环形铁圈，避免锁定凹槽11内端面由于叶片凸轮块22高压力下冲击造成的磨损或毛刺，保护警棍的伸缩功能。
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：本发明中的伸缩警棍采用叶片凸轮锁定组件，伸缩警棍伸出锁定后受阻力不易缩进，且伸缩过程中操作流畅，解锁方便。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
