Description

工作灯
技术领域
本发明涉及照明技术领域，尤其涉及一种工作灯。
背景技术
在照明技术领域，手电筒是一种常见的便携式照明工具，其包括基部和照明部，为照明部供电的部分通常设置在基部内。使用者需手持手电筒，这大大束缚了使用者，不利于使用者同时进行其他操作。为了实际使用的便利，本领域的技术人员在手电筒的基础上进行改进，提出了一种工作灯的结构，这种工作灯使用可弯曲的蛇形管连接基部和照明部，使用者按照不同的情况将蛇形管弯曲，并将弯曲的蛇形管悬挂在周围的某一物体上以固定。
然而这种工作灯，使用时需悬挂在周围的某一物体上固定，这给实际操作带来了很大的限制；一旦固定好工作灯，照明部的照明角度也会固定，调整照明角度时需要调整蛇形管，操作比较麻烦；蛇形管与基部、照明部之间采用卡扣和相应的卡槽连接，一方面这样的连接方式密封性不良，容易导致水或尘土进入基部、照明部或蛇形管的内部；一方面，分开蛇形管与基部或蛇形管与照明部时，容易导致卡扣的损坏，影响整个工作灯的使用寿命。并且，在光线不良或紧急作业的时候，使用者经常错误的组装工作灯，比如将基部和照明部直接连接，连接后却发现无法工作。
因此，本领域的技术人员致力于开发一种新型的工作灯。
发明内容
有鉴于现有技术的上述缺陷，本发明所要解决的技术问题是提供一种新型的工作灯。
为实现上述目的，本发明提供了 一种蛇形管，包括可变形的外管以及设置在所述外管内的可变形的支撑结构和导电部件，其特征在于，所述蛇形管两端具有相同的连接结构。
进一步地，所述蛇形管两端分别具有用于连接外部结构的内螺纹。
进一步地，所述外管为波纹管。
进一步地，所述支撑结构包括配合所述波纹管的星型管。
进一步地， 所述星型管的外缘位于所述波纹管的内径最大处，所述星型管相邻的星型结构之间的间距对应于所述波纹管相邻的内径最大处之间的间距。
进一步地， 所述支撑结构还包括柔性金属丝，所述金属丝设置于所述支撑结构内并贯穿所述支撑结构。
同时，本发明提供了 一种工作灯，包括基部、照明部和开关控件，所述基部内设置有为所述照明部供电的电池，所述基部和所述照明部通过连接部连接，其特征在于，所述基部和所述照明部通过相同的连接结构分别与所述连接部连接 。通过这样的设置，所述基部和所述照明部无法直接连接，使用者使用时不可能出现安装错误。
进一步地，所述连接部包括蛇形管。
进一步地，所述基部和所述蛇形管的第一端螺纹连接；所述照明部和所述蛇形管的第二端螺纹连接。
进一步地 ，所述蛇形管的第一端和第二端的螺纹均为内螺纹。
通过这种连接方式，蛇形管和基部之间、蛇形管和照明部件之间的连接更为紧密，密封性好，可以防止液体或灰尘进入基部或者照明部的内部，有效延长照明灯的使用寿命。此外，分开蛇形管、基部和照明部时，对照螺纹的方向旋开即可，螺纹连接方式相比卡扣和卡槽的配合不易损坏。
进一步地，所述蛇形管包括可变形的外管以及设置在所述外管内的可变形的支撑结构和导电部件。
进一步地，所述外管为波纹管。
进一步地，所述支撑结构包括配合所述波纹管的星型管。

进一步地， 所述支撑结构还包括柔性金属丝，所述金属丝设置于所述支撑结构内。
进一步地， 所述金属丝贯穿所述支撑结构。
通过这种设置方式，星型管和波纹管之间配合紧密，可以有效增加蛇形管的硬度；引入柔性金属丝，进一步加强蛇形管的支撑效果，使用者根据实际需要，对蛇形管施力，使蛇形管变形弯曲，变形后的蛇形管在内部星型管和金属丝的支撑下可以保持目前的形状，这样，即使使用者的周围没有合适的物体支撑蛇形管，蛇形管自身也可以保持目前的弯曲状态，以满足使用者的需求，适用于多种场合。
进一步地，所述蛇形管的一端具有槽，所述蛇形管的另一端具有和所述槽对应的凸条，所述凸条设置为可插入所述槽中。
在蛇形管的两端设置彼此配合的槽和凸条，从而可以通过将凸条插入槽中实现蛇形管的两端相连，减小蛇形管的占据空间，更便于携带和放置。
进一步地，所述工作灯还包括连接套，所述基部和所述照明部通过 连接套连接， 所述基部和所述照明部具有相同的用于连接所述连接套的连接结构。

技术效果
本发明中照明灯的基部和照明部具有相同的连接结构，基部和照明部无法直接连接，使用者使用时不可能出现安装错误。
特别是当照明部分使用有极性要求的LED作为光源时，避免了使用者在连接电源和照明部分时，安装错误的发生。
本发明中照明灯的基部和照明部分别与蛇形管螺纹连接，密封性好，可以防止液体或灰尘进入基部或者照明部的内部，且螺纹连接不易损坏，可有效延长照明灯的使用寿命。
使用绝缘连接套连接基部和照明的照明灯，结构更为紧凑，携带方便；使用可变形的蛇形管连接基部和照明的照明灯，可以根据操作需要， 将蛇形管弯曲以将照明灯固定在某处，使用者无需手持照明灯，便于使用者进行工作。
本发明照明灯的蛇形管包括波纹管、星型管和金属丝，星型管和波纹管之间配合紧密，可以有效增加蛇形管的硬度；引入金属丝，进一步加强蛇形管的支撑效果，使用者根据实际需要，对蛇形管施力，使蛇形管变形弯曲，变形后的蛇形管在内部星型管和金属丝的支撑下可以保持目前的形状，这样，即使使用者的周围没有合适的物体支撑蛇形管，蛇形管自身也可以保持目前的弯曲状态，以满足使用者的需求，适用于多种场合。
在蛇形管的两端设置彼此配合的槽和凸条，从而可以通过将凸条插入槽中实现蛇形管的两端相连，减小蛇形管的占据空间，更便于携带和放置。
本发明中照明部的 灯头设置为可枢转地连接灯头固定部的一端。在外力的作用下，灯头可相对灯头固定部转动以调整灯头的照明角度，应用更加灵活。
