具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案,下面结合附图对本公开提供的固定装置进行详细描述。
本公开实施例提供的固定装置,可用于将诸如摄像头、投影仪、显示器等的设备固定在基础物体上。基础物体包括墙壁或者天花板等等。
在一个实施例中,如图1所示,提供一种固定装置,该固定装置包括安装座1和与之转动连接的支架2,摄像头等设备安装在该支架2上。当支架2的角度调节完成之后,通过螺母3来锁定安装座1与支架2的相对位置,从而将支架2固定在调整后的角度。
上述固定装置需要反复松脱和锁紧螺母3,来实现支架2的角度调节。这种调节方式不仅耗时耗力,有时还需要借助扳手等工具,给操作带来不便,而且反复松脱和锁紧螺母3会导致螺母3的使用寿命缩短,容易失效。
请参阅图2A,本公开实施例提供的固定装置,包括固定件4、活动件5和角度调节组件6。其中,固定件4被构造成与基础物体(图中未示出)固定连接。固定件4与基础物体的连接方式可以有很多种。例如,如图3所示,固定件4包括下盖体42和设置在该下盖体42中的螺钉孔421,用以使下盖体42能够通过螺钉安装在墙壁或者天花板 等的基础物体上。在实际应用中,固定件4的尺寸和形状以及螺钉孔421的数量和排布方式可以根据具体需要自由设定。
活动件5被构造成与诸如摄像头、投影仪、显示器等设备固定连接。活动件5的形状和尺寸可以根据不同形状的设备而进行专门的设计。例如,如图4A和图4B所示,活动件5包括上盖体52,该上盖体52的安装面上设置有卡扣53,用以采用卡接的方式与设备连接。当然,在实际应用中,还可以采用其他任意方式实现上盖体52与设备之间的连接,例如螺钉连接或者其他可拆卸的连接方式。
在一个示例性实施例中,上盖体52中设置有螺钉安装孔54,用以使上盖体52能够通过螺钉安装在基础物体上。螺钉安装孔54的设置,可以将上盖体52直接安装在基础物体上,从而可以增加安装方式,提高安装灵活性,兼容不同设备的安装需求。
在本实施例中,如图2B所示,固定件4还包括第一支架41,活动件5还包括第二支架51。在本实施例中,第一支架41与下盖体42连接,且具有相对设置的两个第一支撑部;第二支架51与上盖体52连接,且具有第二支撑部,该第二支撑部设置在两个第一支撑部之间。
角度调节组件6将活动件5与固定件4转动连接,并且,角度调节组件6被设置为能够活动,以在处于第一位置时能够使活动件5相对于固定件4转动至任意角度。在处于第二位置时,角度调节组件6能够使活动件5固定在该任意角度。只要使角度调节组件6在第一位置和第二位置之间移动,即可实现活动件5在位置可调与位置固定两个状态之间的切换。这样,根据本实施例的固定装置不仅操作方便、定位可靠,而且使用寿命较长,不易损坏。
下面对角度调节组件6的具体实施方式进行详细描述。具体地,如图2B所示,角度调节组件6包括转轴61、设置在该转轴61上的第一限位结构和设置在活动件5上的第二限位结构,其中,转轴61与活动件5转动连接,转轴61与固定件4可移动的连接。在一个示例性实施例中,转轴61贯穿上述两个第一支撑部和第二支撑部,以将固定件 4和活动件5连接在一起。
如图4B所示,第二支架51的第二支撑部中设置有第一转轴孔511;如图3所示,第一支架41的两个第一支撑部分别设置有第二转轴孔411和第三转轴孔412。如图6A和图6B所示,第一转轴孔511、第二转轴孔411和第三转轴孔412均同轴设置,且第一转轴孔511位于第二转轴孔411和第三转轴孔412之间;转轴61穿设于第一转轴孔511、第二转轴孔411和第三转轴孔412中。
进一步地,转轴61能够沿其轴向在第二位置与第一位置之间移动。也就是说,转轴61能够在第一转轴孔511、第二转轴孔411和第三转轴孔412中移动。上述第一限位结构与第二限位结构在转轴61移动至第一位置时相分离,以使活动件5能够围绕转轴61转动至任意角度。第一限位结构与第二限位结构在转轴61移动至第二位置时相配合,以使活动件5能够固定在该任意角度。
在本实施例中,第一限位结构设置在转轴61的外周壁上,第二限位结构设置在第一转轴孔511的孔壁上。第一限位结构和第二限位结构的配合方式可以有多种。例如,如图5所示,第一限位结构包括设置在转轴61的外周壁上的第一凸台611。如图4B所示,第二限位结构包括设置在第一转轴孔511的孔壁上的第二凸台,且在该第一凸台和第二凸台611彼此相对的两个端面上分别设置有第一齿部512和第二齿部612。第一齿部512和第二齿部612在转轴61移动至如图6A所示的第一位置时相分离,在转轴61移动至如图6B所示的第二位置时相啮合。
如图6A所示,当第一齿部512和第二齿部612相分离时,第二支架51能够围绕转轴61转动任意角度;如图6B所示,当第一齿部512和第二齿部612相啮合时,第二支架51的转动自由度被限定,从而相对于转轴61固定不动。容易理解,第二支架51在转轴61的圆周方向上的角度的精确度取决于第一齿部512和第二齿部612的齿数,齿数越多,角度精度越高。
在本实施例中,如图2B所示,角度调节组件6还包括弹性件62,该弹性件62在转轴61受到外力作用时产生弹性变形,且在外力作用解除时向转轴61施加使之复位至如图6B所示的第二位置的弹力。借助弹性件62,可以实现转轴61的自动复位,从而在需要调节活动件5的角度时,向转轴61施加外力即可对活动件5的角度进行调节;在调节完成之后,只需接触外力即可将活动件5固定在调节后的角度,进一步提高了调节便捷性。
弹性件62的结构可以有多种,例如为压缩弹簧。进一步地,如图6A和图6B所示,角度调节装置6还包括端盖63,该端盖63设置在固定件4上,且与转轴61位于第二转轴孔411中的第一端面(图6A和图6B中示出的转轴61的左侧端面)相对设置;此外,压缩弹簧设置在第二转轴孔411中,且位于端盖63与上述第一端面之间,用以在转轴61受到外力作用时产生压缩变形,且在外力作用解除时向转轴61施加使之复位至第二位置的弹力。
如图6B所示,转轴61远离上述第一端面的部分(图6B中示出的转轴61的右侧一端)自第三转轴孔412伸出,用以承受外力作用。具体地,在转轴61未受到外力作用时,转轴61处于如图6B所示的第二位置;当按压转轴61的伸出部分时,转轴61自第二位置移动至如图6A所示的第一位置;当松手时,转轴61在压缩弹簧的作用下自动复位至第二位置。
另外,为了限定端盖63的位置,在第二转轴孔411中还设置有台阶结构414。
在实际应用中,端盖63与固定件4的固定方式有多种,例如为粘贴、螺钉、超声焊接、卡扣等等。
如图5所示,角度调节组件6还包括设置在转轴61上的第一定位结构613和设置在第二转轴孔411中的第二定位结构413,第一定位结构613和第二定位结构413相配合,以限定转轴61的旋转自由度,实现转轴61与固定件4的相对固定。第一定位结构613和第二定位结构 413的配合方式有多种。例如,第一定位结构613和第二定位结构413分别为设置在转轴61的外周壁上的凸部和设置在第二转轴孔411中的凹部,所示凸部与所述凹部相配合。当然,在实际应用中,第二定位结构413也可以设置在第三转轴孔412中,或者在第二转轴孔411和第三转轴孔412中均设置有第二定位结构413。
如图7A和图7B所示,角度调节组件6还包括转动把手7,该转动把手7与转轴61背离第一端面的部分(即,伸出部分)转动连接。转动把手7具有呈夹角的第一表面和第二表面,且被设置为在转动把手7转动至如图7A所示的第一角度时,上述第一表面与第三转轴孔412的端面相抵,以带动转轴61移动至如图6A所示的第一位置;在转动把手7转动至如图7B所示的第二角度时,上述第二表面与第三转轴孔412的端面相抵,以带动转轴61移动至如图6B所示的第二位置。转动把手7可以给操作带来方便。当然,在实际应用中,转动把手7的结构还可以采用其他任意结构,只要能够移动转轴61即可。
综上所述,本公开实施例提供的固定装置,可以借助角度调节组件将活动件与固定件转动连接。该角度调节组件被构造为能够活动,以在处于第一位置时能够使活动件相对于固定件转动至任意角度,在处于第二位置时能够使活动件固定在任意角度。只要使角度调节组件在第一位置和第二位置之间移动,即可实现活动件在位置可调与位置固定两个状态之间的切换。因此,本公开实施例提供的固定装置不仅操作方便、定位可靠,而且使用寿命较长,不易损坏。
可以理解的是,以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式,然而本公开并不局限于此。对于本领域内的普通技术人员而言,在不脱离本公开的精神和实质的情况下,可以做出各种变型和改进,这些变型和改进也视为本公开的保护范围。
