Structure for manually adjusting direction of lamp head, and lamp

Abstract

The invention provides a structure for manually adjusting direction of a lamp head. The structure comprises the lamp head, a support hinged to the lamp head, a rotating disc and a fixed disc, the support is mounted on the rotating disc which is rotatably arranged on the fixed disc, a positioning component is arranged on the outer side of the rotating disc and comprises a supporting seat and inserting pins penetratingly arranged on the supporting seat, positioning holes used for arranging the inserting pins in an inserted manner are uniformly arranged on the circumference of the fixed disc, an arc-shaped guide hole is arranged in the support, and a fastening member is arranged at a position, opposite to the guide hole, on the lamp head, penetrates the guide hole and locks a butterfly-shaped nut. The structure is simple, stable and reliable, and horizontal lighting direction and pitching angle of the lamp head can be adjusted manually without the help of any tools. The invention further provides a lamp which comprises a base box. The lamp is provided with the structure, and the fixed disc is mounted on the base box. The horizontal lighting direction and the pitching angle of the lamp head of the lamp can be conveniently adjusted without the help of any tools.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a structure for manually adjusting the orientation of a lamp head of a lamp and a lamp using the structure. Background technique [0002] Many lamps for special occasions are designed with structures for adjusting the horizontal orientation and pitch angle of the lamp head, such as lamps used in playgrounds, night road construction, night police duty, concert venues, etc. In the existing structure, it is generally necessary to use tools such as screwdrivers or wrenches to adjust the horizontal rotation, azimuth, and pitch angles of the lamp head. The operator needs to carry adjustment tools with him. This adjustment method is inconvenient and time-consuming. Moreover, when adjusting high-altitude lamps, Tools are easy to slip and cause safety hazards. Although some existing structures do not require the use of tools to adjust the horizontal orientation and pitch angle of the lamp head, thes...

AI Technical Summary

Problems solved by technology

In the existing structure, it is generally necessary to use tools such as a screwdriver or a wrench to adjust the horizontal rotation, azimuth, and pitch angle of the lamp head. The operator needs to carry the adjustment tool with him. This adjustment method is inconvenient and time-consuming. Tools are easy to slip, causing safety hazards

Although some existing structures do not require tools to adjust the horizontal orientation and pitch angle of the lamp head, these structures are relatively complicated, have many parts, are inconvenient to operate, and have high manufacturing costs.
