Description

一种激光水平仪
本申请要求于2019年08月02日提交的、申请号为201921244080.X的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及一种激光水平仪，更具体地，涉及一种具有吸附装置及水平珠组件的激光水平仪，其通过吸附装置吸附于安装表面上，通过水平珠组件校验水平仪的水平度。
背景技术
激光水平仪是一种常见的激光对准产品，因其校准精确度高、操作简单、方便携带等优势，在建筑行业及大型机器设备的建造或安装工程中被广泛使用。目前的激光水平仪多是通过紧固件固定在安装表面上，但这种固定方式不便于移动水平仪，安装灵活性差，为了使激光水平仪能够更容易、灵活地固定于安装表面上，现有技术中有通过在水平仪中设置抽吸装置来进行水平仪的安装定位，具体的，该抽吸装置具有电机和泵，工作时，通过电机带动泵抽吸底壳安装区中的空气，以将底壳安装区中的空气排出，形成负压，从而将激光水平仪固定于安装表面上。
然而，上述现有技术中上述由电机和泵所组成的抽吸装置，还需要其他多个辅助部件才能将水平仪吸附于安装表面上，如需要在底壳上用TPE(如TPE350A2)等软胶进行密封，还需要在泵与底壳安装区之间设置用于抽吸空气的软管等，现有技术中的这种类型的激光水平仪整体结构相对复杂，而且，具有上述抽吸装置的激光水平仪适于用于光滑的安装表面，对于较复杂的安装表面(粗燥不平的安装表面)，则难以实现可靠的吸附。
现有技术中的激光水平仪一般会设置一个或多个水平珠用于校准水平仪的水平度，比如设置两个水平珠，其中一个用于X轴校准,另一个用于Y轴校准，但是，在装配每个水平珠时，都需要装配调节和复测，这不仅导致装配时间较长，还会影响水平仪的精度。

可选地，所述壳体上还安装有用于保护所述激光组件的防护罩，所述防护罩上开设有供所述激光组件的激光束射出的标准孔。
采用上述方案后，本公开具有以下有益效果：
本公开中的激光水平仪在使用时通过吸附装置可靠地固定在待测基准的安装表面上，通过吸附装置中电机带动风扇产生吸力的方式，能够快速产生足够的吸力将水平仪定位于复杂的不光滑安装表面上，因此，本公开中的激光水平仪能够在复杂的安装环境中使用，增加了实用性，而且，相比现有技术中由电机和泵所组成的抽吸装置而言，电机和风扇的结构更简单、轻巧，而且与现有技术相比，还省去密封软胶及软管等部件，简化了结构。本公开中校准水平仪水平度的为水平 珠组件，通过将两个水平珠整合为一体，可确保两个水平珠彼此正确定向，这样，在生产装配和使用者使用时，只需在一个轴向上调整水平仪即可校准水平仪的水平度，而且，一体成型在保证精度的同时还降低了加工成本及装配成本，提高生产效率。

具体实施方式
下面根据附图所示实施方式阐述本公开。此次公开的实施方式可以认为在所有方面均为例示，不具限制性。本公开的范围不受以下实施方式的说明所限，仅由权利要求书的范围所示，而且包括与权利要求范围具有同样意思及权利要求 范围内的所有变形。
本公开的一些实施例提供一种激光水平仪，如图1和2所示，该激光水平仪包括壳体1，壳体1内部设置有将壳体1分隔为上、下两部分的隔板11，其中，壳体1的上部分安装有电源装置2和与电源装置2连接的激光组件3，激光组件3通过壳体1上的孔射出对准激光束，指示沿安装表面的基准面。壳体1的下部分安装有将激光水平仪固定于安装表面的吸附装置4，该吸附装置4包括风扇41和驱动风扇41转动的电机42。在部分实施例中，该风扇41为离心风扇、轴流风扇或其他任何合适类型的风扇。在部分实施例中，电机42也与电源装置2连接，与激光组件3共用电源装置2。壳体1的上端部还安装有顶盖12，通过该顶盖12将安装于壳体1上部分的激光组件3等部件收纳于壳体1内部，壳体1的下端部还设置有端盖13。在部分实施例中，顶盖12和/或端盖13与壳体1一体成型。在部分实施例中，端盖13向壳体1内侧凹陷形成腔体131，腔体131上开设有一个或多个吸气口132(见图3)。本公开的一些实施例中激光水平仪上还安装有用于校验水平仪在安装表面上是否处于水平状态的水平珠组件5。
图2和图3显示了本公开的一些实施例中激光水平仪的详细结构，如图2和图3所示，吸附装置4通过电机座43固定于隔板11上，电机42的输出轴421穿过风扇41的轮毂411上的中心孔与风扇41固定连接，当启动电机42后，电机42驱动风扇41持续转动，通过吸气口132抽吸端盖13上腔体131与安装表面之间的空气，以此使端盖13与安装表面之间的空间处于负压状态，从而利用大气压将水平仪吸附于安装表面上。在本公开的部分实施例中，电机42穿过所述隔板11设置，在该穿过处预留有供气体排出的排气口111，吸附装置4所抽吸的空气即从此处排出，然后经由后述标准孔141排出到水平仪外部，另外，也可以从后述观察孔121处排出，或设置其他间隙用于排出气体。
如图3所示，在本公开的部分实施例中，端盖13上的腔体131在与风扇41相对的位置形成，优选腔体131正对风扇41形成。腔体131为向壳体1的内侧凹陷形成，优选腔体131在端盖13一侧的开口大，向壳体1内部凹陷侧的开口小，这样的结构更有助于抽吸空气，腔体131的侧面可选择为平面，也可选择为具有一定弧度的弧形面，优选截面呈等腰梯形状的腔体131，但是，本公开的实施例中腔体131不限于上述形状，只要是能够实现空气抽吸的通道即可。腔体 131的底部133为平面状或近似平面状，其尺寸略大于或等于风扇41的直径，其上开设有一个或多个吸气口132，吸气口132优选开设于风扇41的扇叶412下方附近。在本公开的部分实施例中，具体开设有两个吸气口132，两个吸气口132在底部133上沿扇叶412的分布位置相对应地开设，两个吸气口132整体呈梯形状，对称开设在底部133上。本实施例中吸气口132的形状不限于此，也可以设置为矩形、圆形等。
在本公开的部分实施例中，水平珠组件5是将两个水平珠整合成一体而成的，该水平珠组件5包括一个用于X轴定向的水平珠51和一个用于Y轴定向的水平珠52，在制作该水平珠组件5时，通过调整使两个水平珠处于相互垂直状态安装于承载件53上，然后，再如图5所示，将该水平珠组件5作为整体通过连接件安装于壳体1的上部分，具体的，该水平珠组件5通过由从隔板11向顶盖12一侧延伸的筋板支撑安装。顶盖12上在与水平珠组件5中的水平珠51、52相对应的位置开设有观察孔121，使用者通过该观察孔121来观察水平珠。在本公开的部分实施例中，通过将两个水平珠整合为一体，可确保两个水平珠彼此正确定向，能够进一步保证安装精度及测量精度，这样也能够进一步降低加工成本及装配成本。
如图4所示，在本公开的部分实施例中，上述承载件53上还可形成有用于安装激光组件3的安装位置54，即，在生产制造时，将激光组件3也一体地安装在该水平珠组件5上，将其作为一个整体来使用。具体的，激光组件3包括激光发射器31，以及用于对激光发射器31发出的激光进行聚焦的透镜32，将激光发射器31安装于安装位置54处的安装孔中，再将透镜32设置于激光发射器31的前方，透镜32通过透镜支架33承载并定位于激光发射器31的前方，透镜支架33可以通过卡扣结构或者螺钉连接等方式固定在承载件53上。通过这种方式，即在生产制造时便调整好激光组件与水平珠的位置关系，能够进一步保证安装精度及测量精度，这样也能够进一步降低加工成本及装配成本，整合为一体也能更好的保证其上各部件的相对位置关系。另外，也可仅将激光组件3中的激光发射器31安装在承载件53上，将激光发射器31与水平珠组件作5整合为一体，作为一个整体使用。当然，也可仅将水平珠组件5作为一个整体，将激光组件3单独安装于壳体1上部。
在本公开的部分实施例中，在激光组件3激光束射出的位置，在壳体1和顶盖12上相应开设有供激光束射出的孔，另外，还可设置用于进一步保护激光组件3的防护罩14，防护罩14与顶盖12和壳体1连接，其上也开设有供激光束射出的标准孔141。
在本公开的部分实施例中，激光组件3和吸附装置4共用电源装置2，如图5所示，电源装置2为电池组，电池组可选用可充电电池组，例如锂离子电池或镍镉电池，另外也可选用可拆卸的碱性电池，在壳体1的侧壁上还相应设置有电源装置2的电源开关21，电源开关21可以采用如图所示的滑动开关，也可采用其他形式的开关。在本公开的部分实施例中，电池组安装于隔板11上，并分布于激光组件3的两侧，通过这种布置能充分利用壳体1上部分的空间，使水平仪的整体体积更小。本实施例中激光组件3和电机42共用电源装置2，当然，也可分别设置电源及各自对应的电源开关。
在本公开的部分实施例中，电机42部分穿过隔板11安装，即，电机42部分位于壳体1上部，部分位于壳体1下部，如此设置能够使水平仪的结构更紧凑，当然，也可将电机42安装于壳体1的下部分。
在本公开的部分实施例中，端盖13采用硬胶(ABS 121H)等材料，通过电机带动风扇快速转动，通过风扇抽吸空气形成负压以将水平仪吸附于墙面等安装平面上，无需像现有技术中那样在端盖上设置软胶进行密封。
在本公开的部分实施例中，激光组件3中的激光发射器31选用常见的激光发射部件如半导体激光器等，具体可选用如发光二极管。
在本公开的部分实施例中，用风扇结构代替现有技术中泵，不仅简化吸附装置的结构，使水平仪整体更轻巧，而且以电机带动风扇转动的方式，能够快速抽吸腔体与安装表面之间的空气，也就能够尽快将水平仪固定到安装表面上，通过电机带动风扇的方式能够快速产生足够的吸力，能够将水平仪吸附到不光滑的安装面上，增加了水平仪的实用性；其次，吸附装置的结构简化同时也降低了拆装难度，便于维修和维护保养，降低了使用成本。
