Abstract

The invention belongs to the technical field of lighting equipment, particularly relates to a bendable lighting device for underground construction. The bendable lighting device is mainly composed ofa lamp body, a lamp cap, front supports, an elastic cushion, back supports, a support base, a power source, a metal flexible conduit and the like; and the front end of the lamp body is in threaded connection with the back end of the lamp cap, the tail of the lamp cap is electrically connected with the power source through the metal flexible conduit, the metal flexible conduit is installed in the lamp body in a coiled manner, the lower end of the lamp body is rotationally connected with the upper end of the support base, and the front supports and the back supports of the support base can be buckled to the shoulders of the human body after being unfolded. The back right support of the device is provided with a shoulder supporting hook, the lamp body buckled to the shoulder of the human bodycan be prevented from falling, the lamp cap and the lamp body can be subject to rotary separation, use is convenient, the lamp cap and the power source are connected through the metal flexible conduit, the lamp cap can do multi-azimuth rotation by 360 degrees, and the device has flexibility, can better adapt to various complex underground operating environments and is particularly suitable for underground pipe network overhauling type small-space operation.

Description

Technical field: [0001] The invention belongs to the technical field of lighting equipment, and relates to a portable lighting device for underground construction, in particular to a bendable lighting device for underground construction, which can be fixed on the shoulder of a human body or placed on an underground construction site , The lighting head is detachable, flexible and convenient to use, suitable for maintenance and construction operations in various underground pipelines or large equipment rooms. Background technique: [0002] With the rapid development of society today, the development and utilization of underground space has become a major trend in urban construction.
