Description

一种激光投线仪 技术领域
本实用新型涉及一种激光投线仪，尤其是涉及一种具有可以方便对摆动 杆进行固定的中心锁的激光投线仪。 坟不¾
激光投线仪是一种能在墙面、 地面和天顶投射可视的激光十字水平线 (或激光点）和垂直线（或激光点）的精密仪器， 被广泛地应用于室内装饰 行业。 自动按平激光投线仪能够在一定的倾斜范围内确保投射出来的激光线 保持水平线和垂直线的精度以及水平垂直线相交 90度夹角的精度，。激光投 线仪一般具有一个重力摆垂体， 在该重力摆垂体的重力作用下， 使得安装在 重力摆垂体上的激光器发出激光光线保持处于水平和垂直状态，从而保证了 施工的准确度，然而建筑领域的工作环境都会比较恶劣，且难免会产生振动。 另外， 在运输的过程中， 需要将垂体进行固定， 以防止在运输过程中因垂体 的晃动而损坏投线仪。 从仪器的另外一个使用的角度看， 由于有锁紧机构， 使得自动按平激光投线仪在重力摆被锁紧后，利用其它辅助的设备使得仪器 程倾斜状态， 从而实现坡度的施工要求。
为了解决上述的问题， 现有技术中的激光投线仪采用一种夹紧装置， 该 夹紧装置通过一个夹紧片， 将重力摆垂体推至激光投线仪的一侧， 使其靠在 内壁上， 从而提供夹紧。
然而， 这样的夹紧装置也会产生问题， 首先， 靠于一侧的夹紧会使悬挂 重力摆垂体的轴承受到侧向的力， 从而损坏轴承或使得精度失效。 且， 重力 摆垂体如果侧靠于一侧， 则在夹紧时使用受到限制， 仅在该重力摆垂体处于 摆动灵活或者自然状态时才能够保证激光器发出激光的标线精度质量，而使 得重力摆垂体保持灵活和精度的承载轴承的受力均匀性显得非常重要，但是 现有的夹紧设备不具备这项功能， 而且， 也不方便操作。 发明概要
本实用新型解决的技术问题是针对现有技术的不足，提供一种可以方便 对摆动杆进行固定的激光投线仪。
为解决上述问题， 本实用新型提供一种激光投线仪， 包括机体、悬挂在 机体上的摆动杆， 一中心锁设置于机体的下部， 该中心锁包括锁紧联动片、 滑块、锁紧导向片及锁紧夹紧片， 上述锁紧联动片、 锁紧导向片上均具有中 心孔， 上述摆动杆自中心孔穿过， 上述锁紧联动片与上述机体固接， 在锁紧 联动片上沿径向开设有两个联动槽，且于上述锁紧联动片上向下方延伸形成 两个滑动柱， 上述滑块上开设有可以收容上述滑动柱的滑动槽， 一拨动柱自 上述滑块上向外延伸出上述机体，上述滑块朝向中心孔的一侧向内形成收容 槽， 上述锁紧导向片设置于上述锁紧联动片上， 且其向下延伸有导向柱， 该 导向柱收容于上述收容槽内， 在上述锁紧导向片上还开设有两导向槽， 该两 导向槽平行设置且平行于上述中心孔的切线方向， 锁紧夹紧片共有两片， 其 朝向上述中心孔方向具有弧形凹进，且在上述两个锁紧夹紧片均具有一夹紧 柱， 上述夹紧柱收容于上述导向槽内。
本实用新型还具有以下特征：所述锁紧联动片上对应于所述导向柱位置 向内形成凹槽， 所述导向柱即自凹槽位置凸伸而出， 所述两个滑动柱的连线 与上述联动槽不平行， 所述机体外进一歩设置有壳体， 所述壳体上设置有旋 转手柄， 该旋转手柄具有拨片， 该拨片上具有拨槽， 用以收容上 ¾拨动柱， 所述旋转手柄与所述拨片之间具有定位片， 所述定位片的顶端具有定位凸 起。
通过本实用新型，该激光投线仪能够提供方便准确的摆动杆的定位及夹 紧， 保护激光投线仪免受损害。 附图说明
下面结合附图及具体实施方式对本实用新型作进一步描述。

图 2是本实用新型一种激光投线仪去除外壳体的立体组装图。
图 3是本实用新型一种激光投线仪有关摆动杆及中心锁的分解示意图。 图 4是本实用新型一种激光投线仪有关摆动杆及中心锁的组装示意图， 其中显示中心锁在开启状态。
图 5是本实用新型一种激光投线仪有关摆动杆及中心锁的组装示意图， 其中显示中心锁在闭合状态。 发明内容
请参阅图 1及图 2所示，本实用新型的激光投线仪 100包括机体 1及设 置于机体 1外的壳体 2， 在机体 1的下部具有摆动杆 4， 摆动杆 4具有激光 器 3， 用于产生激光线 （点）进行投线作业， 在摆动杆 4的顶端设置有摆动 锤 41。 壳体 2上设置有旋转手柄 5， 该旋转手柄 5上具有拨片 51， 在拨片 N2007/003020
51的顶端具有拨槽 511。 在机体 1的下部设置有中心锁 6， 中心锁 6的中央 位置具有中心孔 61， 该中心孔 61可以收容上述摆动杆 4， 使其自中心孔 61 穿过。中心锁 6由锁紧联动片 62，设置于锁紧联动片 62上的锁紧导向片 63， 设置于锁紧导向片 63上的锁紧夹紧片 64及设置于锁紧联动片 62下方的滑 块 65组成， 在滑块 65的向外一侧， 延伸出拨动柱 651， 该拨动柱 651收容 于上述拨槽 511。
请参阅图 2及图 3所示， 锁紧联动片 62通过螺钉 （未标号） 固定于机 体 1上， 且其上沿径向开设有两个不相连的联动槽 621， 两个联动槽 621处 于同一直线上。 在锁紧联动片 62上向下方延伸形成两个滑动柱 622， 滑块 65上开设有可以收容上述滑动柱 622的滑动槽 652， 上述滑块 65朝向中心 孔 61的一侧向内凹陷形成收容槽 653。 上述两滑动柱 622的连线与联动槽 621非平行设置，而在上述滑块 65上的收容槽 653为两个，平行设置，这样 可以增大整个滑块 65产生翻转的转矩。上述锁紧导向片 63设置于上述锁紧 联动片 62上，且其向下延伸有导向柱 631，该导向柱 631收容于上述收容槽 653内， 锁紧联动片 62上对应于上述收容槽 653的位置开设有凹槽 623。在 上述锁紧导向片 63上还开设有两导向槽 633，该两导向槽 633平行设置且平 行于上述中心孔 61的切线方向。在锁紧导向片 63的外侧具有向内形成的阻 挡凹陷 632， 该阻挡凹陷 632可以与机体 1进行配合， 防止锁紧导向片 63 过分旋转。锁紧夹紧片 64共有两片， 其朝向上述中心孔 61方向具有弧形凹 进 641， 且在上述两个锁紧夹紧片 64均具有一夹紧柱 642， 上述夹紧柱 642 收容于上述导向槽 633内。
请配合参阅图 3、图 4及图 5所示，旋转手柄 5与拨片 51之间设置有定 位片 52， 在定位片 52的顶端具有定位凸起 521， 该定位凸起 521与壳体 2 (请参阅图 1所示）的内壁进行定位， 加强旋转手柄 5与壳体 2之间的摩擦 力， 防止其自由转动。在中心锁 6处于开启状态时，摆动杆菌 4自中心孔 61 之内穿过， 从而在摆动锤 41 的重力作用下， 处于竖直位置。 此时， 导向柱 631处于上述凹槽 623的一端， 而两滑动柱 622处于两滑动槽 652的一端， 夹紧柱 642处于导向槽 633的最外侧，且透过上述导向槽 633处于上述联动 槽 621的最外侧。 拨动上述旋转手柄 5， 则拨片 51的拨槽 511带动拨动柱 651横.向运动，则上述导向柱 631在滑块 5的 65的带动下沿圆周运动，因此 整个锁紧导向片 63进行旋转运动， 进而推动夹紧柱 642沿着导向槽 633的 方向向内侧移动。 因为夹紧柱 642与锁紧夹紧片 64固定连接， 所以锁紧夹 紧片 64也在夹紧柱 642的带动下向内侧夹紧， 从而两弧形凹进 641可以摆 动杆 4进行定位， 且摆动杆 4可以在两弧形的引导下， 处于中心孔 61的中 心位置。在需要将已经锁紧的中心锁 6打开时， 只需要将上洚旋转手柄 5拨 回即可。
综合上述， 本实用新型完成了设计人的设计目的， 使用本实用新型的激 光投线仪， 如果锁紧上述中心锁 6， 在水平放置时， 可以保证摆动杆 4由于 重力的重用自动地垂直定位， 从而使激光器 3发出的激光光线（点）仍能处 于水平及垂直的状态。在锁紧后， 激光线（点） 同样仍然能够保持原有的激 光线（点） 的位置， 并且， 通过一个外部的倾斜调整机构， 可以使得激光仪 器投射的水平垂直交叉线实现稳定的带倾斜角度的坡度线， 便于施工等作 业。 另外， 在运输及保管时， 锁紧后可以方便运输， 不至于因为摆垂体过度 晃动受到撞击而损坏， 更加保护的是， 避免了由于仪器的摆垂体长期处于锁 紧状态下， 由于支撑重力摆体产生自动按平的 4个微型轴承受到侧向受力而 产生精度失效或损坏， 导致激光投线仪的精度失效。 本实用新型的中心锁 6 的操作也很方便， 且弧形的凹进也可以进行自动定心的锁定。
