技术领域technical field
本实用新型涉及灯具的技术领域，具体地是一种工作灯。The utility model relates to the technical field of lamps, in particular to a work lamp.
背景技术Background technique
工作灯一般在紧急情况下进行照明使用，例如室内断电，此时用户需要在使用应急灯照明的情况下进行相应的电路维修、更换灯泡或者拆装变压器等操作。而这一系列需要用户运用双手的操作都会使用户无法正常的拿握应急灯，因此，在生活中，往往需要由另外的人员进行辅助使用应急灯，或者由操作人员使用嘴咬、歪脖子夹持等不方便的动作使用应急灯。Work lights are generally used for lighting in emergency situations, such as indoor power outages. At this time, users need to perform corresponding circuit repairs, replace light bulbs, or disassemble transformers under the condition of using emergency lights for lighting. And this series of operations that require the user to use both hands will make the user unable to hold the emergency light normally. Therefore, in daily life, it is often necessary for another person to assist in using the emergency light, or the operator uses the mouth to bite, crooked neck clamp Hold and wait for inconvenient actions to use emergency lights.
现有技术中为了解决用户单独使用应急灯作业不方便的问题，往往是在现有的应急灯上设置磁块安装件的方式解决，即通过磁块的吸力将应急灯吸附于铁件上，从而便于操作人员使用。但是磁铁吸附过程中，在吸合的一瞬间冲击力很大，容易造成磁块碎裂，而设置弹性缓冲层又会减弱磁块的吸附力。In the prior art, in order to solve the problem that the user is inconvenient to use the emergency light alone, it is often solved by installing a magnetic block mounting part on the existing emergency light, that is, the emergency light is adsorbed to the iron by the suction force of the magnetic block. So that it is convenient for the operator to use. However, during the adsorption process of the magnet, the impact force is very large at the moment of attraction, which may easily cause the magnetic block to be broken, and the installation of an elastic buffer layer will weaken the adsorption force of the magnetic block.
发明内容Contents of the invention
本实用新型所要解决的技术问题是：提供一种在不减弱磁块的吸附力的基础上使磁块在吸合的瞬间撞击力小从而防止磁块碎裂的一种工作灯。The technical problem to be solved by the utility model is: to provide a work lamp which makes the impact force of the magnetic block small at the moment of attraction without weakening the adsorption force of the magnetic block so as to prevent the magnetic block from breaking.
本实用新型所采取的技术方案是：提供一种工作灯，它包括灯体，其特征在于：所述灯体上设有壳体，壳体内设有磁块，所述壳体内位于磁块所对应的侧壁上设有沿竖直方向设置的盲孔，盲孔内设有滑块，滑块与沉孔的内壁滑动配合，所述滑块的下端面和沉孔的内表面合围形成一气压随滑块的滑动变化的气腔，所述气腔内设有驱使滑块的上端面延伸至壳体上端面上方的复位弹簧，复位弹簧的两端分别与盲孔底部和滑块的下端面相抵靠，壳体上设有一端与气腔相连通，另一端贯穿壳体的外表面且与外部环境相连通的气孔，所述滑块的上端面上固定有一弹性缓冲气囊，滑块上设有贯穿滑块的上下端面用于连通弹性缓冲气囊和气腔的气管。The technical solution adopted by the utility model is to provide a work lamp, which includes a lamp body, and is characterized in that: the lamp body is provided with a housing, and a magnetic block is arranged inside the housing, and the housing is located inside the magnetic block. The corresponding side wall is provided with a blind hole along the vertical direction, and a slider is arranged in the blind hole, and the slider is slidably matched with the inner wall of the counterbore, and the lower end surface of the slider and the inner surface of the counterbore are enclosed to form a The air pressure changes with the sliding of the slider. The air cavity is equipped with a return spring that drives the upper end surface of the slider to extend above the upper end surface of the housing. The two ends of the return spring are respectively connected to the bottom of the blind hole and the bottom of the slider. The end faces are against each other, and the housing is provided with an air hole with one end communicating with the air cavity and the other end penetrating the outer surface of the housing and communicating with the external environment. An elastic cushioning airbag is fixed on the upper end of the slider. The upper and lower end faces of the sliding block are provided to communicate with the elastic buffer air bag and the air pipe of the air cavity.
采用以上结构后，本实用新型的一种工作灯与现有技术相比具有以下优点：第一、当磁块与铁件吸合时，所述磁块与铁件之间无缓冲层阻隔，二者的吸合效果好，第二、当磁块与铁件吸合撞击的瞬间，通过滑块将冲击力转换为气腔内空气的内能，达到保护磁块的目的，第三，当铁件完全与磁块吸合时，通过气孔将气腔内的高压空气排出，由此减小了磁吸力的抵消，第四、通过弹性缓冲气囊可以减少滑块上端面与铁件的撞击力，防止滑块上端面损坏。上述技术方案最终实现在不减弱磁块的吸附力的基础上使磁块在吸合的瞬间撞击力小从而防止磁块碎裂的目的。After adopting the above structure, a work lamp of the present invention has the following advantages compared with the prior art: first, when the magnetic block and the iron piece are attracted, there is no buffer layer between the magnetic block and the iron piece, The suction effect of the two is good. Second, when the magnetic block and the iron piece are attracted and collided, the impact force is converted into the internal energy of the air in the air cavity through the slider to achieve the purpose of protecting the magnetic block. Third, when When the iron piece is completely attracted to the magnetic block, the high-pressure air in the air cavity is discharged through the air hole, thereby reducing the offset of the magnetic attraction force. Fourth, the impact force between the upper end surface of the slider and the iron piece can be reduced through the elastic buffer airbag , to prevent damage to the upper end surface of the slider. The above technical solution ultimately achieves the purpose of reducing the impact force of the magnetic block at the moment of attraction without weakening the adsorption force of the magnetic block, so as to prevent the magnetic block from breaking.
