Description

照明灯具 技术领域
本发明涉及照明设备技术领域，尤其涉及一种照明灯具。
背景技术
灯具是指能透光、分配和改变光源光分布的器具，包括除光源外所有用于固定和保护光源所需的全部零部件，以及与电源连接所必需的线路附件，灯具主要包括台灯、壁灯等。
台灯一般用在阅读、书写、设计、批阅等办公或学习照明等场所。对于做桌面工作的人来说，保证工作区的良好的视觉环境，对提高学习和办公的质量，提高工作效率及保护身体健康有很大的好处。灯光亮度及均匀度应当与周围环境的亮暗情况相配合，灯光与环境亮度不宜相差太大。通过旋转调节光源高度及方向来均衡亮度与均匀度的关系，避免眼睛疲劳，打造舒适健康的光环境。
现有的灯具一般由两个可以相对滑动的支杆来分别连接底座与灯头，两个支杆之间具有一个固定结构，需要调节高度时，松开固定结构，即可对灯头的高度进行调节，调节完毕后，重新利用固定结构将连个支杆固定即可。这种灯具在每次进行高度调节时，都需要先后两次改变固定结构的状态，操作麻烦。
发明内容
本发明公开一种照明灯具，以解决现有的灯具在进行高度调节时操作麻烦的问题。
本发明的实施例是这样实现的：
基于上述的目的，本发明的实施例公开了一种照明灯具，包括灯杆、灯头以及自锁装置，所述自锁装置包括壳体、调节按钮、弹性件和钢珠，所述 壳体包括控制槽，所述控制槽的横截面积沿所述壳体的第一端朝向第二端的方向逐渐增大；所述调节按钮与所述壳体的第一端滑动配合，且所述调节按钮的第一端位于所述控制槽内，所述调节按钮包括第二通孔，所述钢珠安装于所述调节按钮的第一端，且所述钢珠能够沿所述调节按钮的径向相对于所述调节按钮移动，所述钢珠的一侧与于所述第二通孔内，所述钢珠的另一侧与所述控制槽的侧壁接触；所述弹性件令所述调节按钮具有朝向所述壳体的第一端移动的趋势，所述灯杆与所述第一通孔间隙配合，所述灯头安装于所述壳体。
本发明采用的技术方案能够达到以下有益效果：
本发明公开的照明灯具的灯头可以是与壳体连接，灯杆可以穿插在第二通孔内，且灯杆与第二通孔可以是间隙配合，调节按钮的第一端在弹性件的作用下具有朝向壳体的第一端移动的趋势，此时钢珠在控制槽的挤压力作用下将灯杆卡紧，在需要使灯头的高度降低时，按动调节按钮，当调节按钮克服弹力朝向壳体的第二端移动时，钢珠对灯杆的挤压力变小，自锁装置能够相对于灯杆滑动，此时在按压力的作用下，自锁装置会带着灯头向下移动，当撤销调节按钮上的压力时，调节按钮在弹性件的作用下，朝向壳体的第一端移动，钢珠在控制槽的挤压作用下将灯杆卡紧，令自锁装置与灯杆锁紧，完成自锁，此时灯头的位置被固定。
当需要使灯头的高度升高时，在壳体的底部提供一个抬升力，而在调节按钮的顶部施加一个较小的压力，令调节按钮朝向壳体的第二端移动一段距离，当钢珠对灯杆的挤压力变小后，自锁装置即可在抬升力的作用下带动灯头上升，当灯头上升至合适的高度后，同时松开抬升力和压力，即可实现自锁。
本发明公开的照明灯具只需按压调节按钮即可实现灯头高度的调整，松开后即可形成自锁，完成固定，操作简单。

请参考图1和图2，本发明实施例公开一种照明灯具，其包括自锁装置10、灯杆20以及灯头30，参阅图3至图5，自锁装置10包括壳体100、调 节按钮200、弹性件300和钢珠400。
壳体100可以是安装在灯杆20上，且壳体100与灯杆20滑动配合，使壳体100能够沿灯杆20的轴线方向相对于灯杆20滑动，壳体100包括控制槽111，控制槽111的横截面积沿壳体的第一端朝向第二端的方向逐渐增大。
调节按钮200安装于壳体100，且调节按钮200与壳体100之间可以相对滑动，调节按钮200的第一端伸入壳体100内，且调节按钮200的第一端位于控制槽111内，调节按钮200的第二端位于壳体100外，并可以在调节按钮200第二端的外壁上设置把手240，以方便着力，把手240与调节按钮200之间可以是螺接或者卡接等方式结合，也可以是采用一体成型工艺制成。
调节按钮200具有第二通孔210，灯杆20可以穿过第二通孔210，且灯杆20与第二通孔210之间可以间隙配合，在壳体100相对于灯杆20滑动时，调节按钮200也能随着壳体100一起相对于灯杆20滑动。
钢珠400位于调节按钮200的第一端，且钢珠400能够沿调节按钮200的径向相对于调节按钮200移动，钢珠400的一侧位于第二通孔210内，钢珠400的另一侧与控制槽111的侧壁抵接，当调节按钮200朝向壳体100的第二端移动时，由于控制槽111的横截面积增大，此时钢珠400位于第二通孔210内的部分会减少，此时钢珠400对灯杆20的挤压力减小，调节按钮200能够带动壳体100相对于灯杆20移动，当调节按钮200朝向壳体100的第一端移动时，由于控制槽111的横截面积减小，此时钢珠400位于第二通孔210内的部分会增多，此时钢珠400对灯杆20的挤压力变大，自锁装置10与灯杆20之间形成固定。
弹性件300安装于壳体100与调节按钮200之间，弹性件300令调节按钮200具有朝向壳体100的第一端移动的趋势，从而使调节按钮200在不受外部挤压力之后，能在弹性件300的作用下朝向壳体100的第一端移动，进而使钢珠400将灯杆20卡紧，形成自锁。
灯头30可以是安装在自锁装置10的壳体100上，灯头30可以随着壳体 100相对于灯杆20移动。
本发明公开的照明灯具的灯头30可以是与壳体100连接，灯杆20可以穿插在第二通孔210内，且灯杆20与第二通孔210可以是间隙配合，调节按钮200的第一端在弹性件300的作用下具有朝朝向壳体100的第一端移动的趋势，此时钢珠400在控制槽111的挤压力作用下将灯杆20卡紧，在需要使灯头30的高度降低时，按动调节按钮200，当调节按钮200克服弹力朝向壳体100的第二端移动时，钢珠400对灯杆20的挤压力变小，自锁装置10能够相对于灯杆20滑动，此时在按压力的作用下，自锁装置10会带着灯头30向下移动，当撤销调节按钮200上的压力时，调节按钮200在弹性件300的作用下，朝向壳体100的第一端移动，钢珠400在控制槽111的挤压作用下将灯杆20卡紧，令自锁装置10与灯杆20锁紧，完成自锁，此时灯头30的位置被固定。
当需要使灯头30的高度升高时，在壳体100的底部提供一个抬升力，而在调节按钮200的顶部施加一个较小的压力，令调节按钮200朝向壳体100的第二端移动一段距离，当钢珠400对灯杆20的挤压力变小后，自锁装置10即可在抬升力的作用下带动灯头30上升，当灯头30上升至合适的高度后，同时松开抬升力和压力，即可实现自锁。
本发明公开的照明灯具只需按压调节按钮200即可实现灯头30高度的调整，松开后即可形成自锁，完成固定，操作简单。自锁装置10安装到灯杆20上时，可以让调节按钮200的把手240朝向灯杆20的上方，也可以让调节按钮200的把手240朝向灯杆20的下方。
其中，弹性件300可以是弹簧或者橡胶等，弹性件300可以是呈压缩状态当弹性件300此时，弹性件300可以是安装在壳体100的底部与调节按钮200的第一端之间，或者将弹性件300的一端安装在壳体100的顶部或者外壁上，然后将弹性件300的另一端安装于调节按钮200的把手240，此时利用弹性件300的弹力，可以让调节按钮200具有朝向壳体100的第一端相对 于壳体100移动的趋势。
在本实施例的一些实施方式中，自锁装置10可以包括至少两个钢珠400，钢珠400与调节按钮200之间活动连接，至少两个钢珠400沿第二通孔210的周向均匀分布。
灯杆20根据不同的应用场景以及不同的客户需求，可以将灯杆20的横截面设计成任意的形状，此时利用自锁装置10都能实现灯头的快速调节以及自动锁死。
在本实施例中，可以将灯杆20设置成圆柱形，在需要使灯头30绕灯杆20的轴线转动时，由于调节按钮200是与壳体抵紧的，钢珠400的两侧是分别与灯杆20和壳体100抵接的，且至少两个钢珠400会在灯杆20和壳体100之间形成较为对称的支撑力，此时拨动灯头30，由壳体100、钢珠400以及灯杆20组成的结构类似轴承的结构，壳体100可以带动灯头30相对于灯杆20转动。
调节按钮200在弹性件300的作用下朝向壳体100的第一端移动时，钢珠400会相对于灯杆20移动一段距离后，钢珠400才能对灯杆20形成足够大的挤压力以形成自锁，呈球状的钢珠400由于其表面较为光滑，因此，其与灯杆20之间的摩擦较小，可以减小对灯杆20的磨损，从而使灯杆20在使用较长的一段时候后仍然能够保持较为完整的外观。
在第二通孔210的侧壁上可以开设用于安装钢珠400的凹槽220，凹槽220的设置可以方便钢珠400与调节按钮200结合，凹槽220的长度小于钢珠400的直径，以使钢珠400的两侧可以分别与灯杆20和壳体100形成抵接，且能够控制钢珠400凸出第二通孔210内壁的大小，从而避免钢珠400将调节按钮200和灯杆20卡死。
在设置凹槽220时，可以让凹槽220的横截面呈圆形，在此所述的横截面是指沿垂直于凹槽220延伸方向上的横截面，此时可以对钢珠400形成限位，避免钢珠400沿调节按钮200的周向发生晃动。
其中，可以让凹槽220与第二通孔210连通的一端的直径小于钢珠400的直径，这样可以让钢珠400始终位于调节按钮200和壳体100之间，避免在将自锁装置10安装到灯杆20上或者当自锁装置10从灯杆20上脱离时钢珠400从自锁装置10内掉落。
凹槽220背离第二通孔210的一端的直径可以是等于或者大于钢珠400的直径，且可以让凹槽220的直径沿调节按钮200的径向向外的方向逐渐增大，即让凹槽220的直径沿凹槽220背离第二通孔210的方向逐渐增大，这样可以保证钢珠400在凹槽220内顺利滑动，且在按动调节按钮200时，钢珠400能够在重力的作用下沿凹槽220的侧壁朝向壳体100滚动，从而使钢珠400脱离与灯杆20的接触，在自锁装置10相对于灯杆20移动时，可以避免钢珠400将灯杆20划伤，从而保证灯杆20的美观。
参阅图7和图8，在本实施例的一些实施方式中，调节按钮200的第一端的外径大于控制槽111的最小直径，以避免当调节按钮200在沿背离壳体100的第一通孔121的方向移动时与壳体100脱离。
可以在调节按钮200的第一端设置斜面230，斜面230位于调节按钮200的外壁，斜面230的设置令调节按钮200的第一端的外径从调节按钮200的第二端至第一端的方向逐渐增大。
利用该斜面230与横截面积逐渐缩小的控制槽111配合，可以让调节按钮200的第一端更好的进行收缩，在钢珠400将灯杆20卡紧的同时，调节按钮200在弹性件的作用下也与壳体100卡紧，从而实现快速锁紧，避免在调节按钮200失去外力后，出现自锁装置10沿灯杆20滑动的情况。
参阅图6，在本实施例的一些实施方式中，壳体100可以包括外壳110和锁盖120，锁盖120与外壳110之间可以是通过卡扣、螺纹或者螺钉锁合结构连接，以方便锁盖120与外壳110之间的拆装。锁盖120上可以设置第一通孔121，第一通孔121与控制槽111连通，且第一通孔121可以是与第二通孔210同轴设置，第一通孔121与灯杆20之间也可以是间隙配合，控制 槽111可以位于外壳110内，为了减小弹性件300受到的侵蚀，可以将弹性件300安装在壳体100内，即将弹性件300安装在锁盖120和调节按钮200的第一端之间，这样便于安装，同样的，也便于更换。
第一通孔121的直径可以略大于灯杆20的直径，而第二通孔210的直径可以是与第一通孔121的直径相等，从而方便灯杆20在第一通孔121和第二通孔210内移动。由于调节按钮200是安装在壳体100的控制槽111内的，因此，第二通孔210的直径应该小于控制槽111的最小直径，以使调节按钮200在安装到壳体100内后能够流畅的相对于壳体100滑动。
外壳110可以是由锁盖120上的凸起而形成，凸起可以是呈环状，也可以是由至少两个单独的凸起，绕第一通孔121的轴线间隔布置而形成，且至少两个凸起应该绕第一通孔121的轴线均匀设置，需要说明的是，当凸起呈环状时，横截面积为凸起围成的圆的面积，而当凸起沿第一通孔121的轴线间隔设置时，横截面积为凸起所围成的图形的面积。
凸起的数量与钢珠400的数量相等，且凸起与钢珠400一一对应设置，此时，当调节按钮200朝向壳体100的第一端相对于壳体100移动时，钢珠400受到凸起的挤压也会对灯杆20形成挤压力，从而将灯杆20卡紧。
在凸起呈环形时，凸起围成的外壳110的第二端与锁盖120结合，而外壳110的第一端的内径小于其第二端的内径。
在本实施例的一些实施方式中，灯头30可以包括连接部31和照明部32，连接部31与壳体100连接，照明部32与连接部31背离壳体100的一端连接，且照明部32与连接部31转动连接，照明部32的转动轴线与灯杆20的轴线垂直，且照明部32的转动轴线与灯杆20的轴线位于同一平面内。
此时灯头30可以实现前后旋转，再利用上述的自锁装置10，还能实现灯头30的上下移动的左右旋转，调节方便，让用户在使用时更加便捷。
参阅图1和图2，在本实施例的一些实施方式中，灯头30可以设置成圆形，也可以设置成方形，由于灯头30是包括连接部31和照明部32的，因此 在设置灯头30整体的形状时，可以根据用户的不同需要，令连接部31和照明部32的形状相同或者不同，当然，圆形和方形只是本实施例的一些实施方式，在其他的实施方式中，将灯头30设置成其他形状也是可以的。
本实施例所述的照明灯具可以是台灯，也可以是落地灯等。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理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权利要求范围之内。
