Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a ceiling lamp with an easily adjustable lamp head. Background Art

[0002] Ceiling lamps are often used for lighting in indoor home decoration and commercial places. As a kind of embedded lamp, ceiling lamps are usually embedded in the ceiling of the building during installation, and the downlight body is hidden. Since ceiling lamps have a small beam angle and use a high degree of focusing, the light has a strong expressiveness. It can play a leading role in overall lighting and can also provide local lighting. It has been widely used in the lighting market.

[0003] However, in order to ensure stability when adjusting the angle of the existing ceiling lamp, the stability is ensured by clamping and squeezing the rotating shaft. On the one hand, the angle adjustment accuracy is low by directly rotating the rotating shaft; on the other hand, the driving shaft directly bears the weight of the lamp body, resulting in a large torque when the lamp body is flipped to a certain angle. Although the clamping design is adopted, it is still easy to loosen after long-term use; therefore, there are limitations. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a ceiling lamp with an easy-to-adjust lamp head. Rotating the rotating motor drives the first gear to rotate, drives the belt assembly to transmit, drives the second gear to rotate, drives the two threaded rods to rotate at the same time, and the two moving blocks are restricted by the connecting blocks and are driven by the threaded rods to move in the horizontal direction, driving the two connecting blocks to move, driving the top of the rotating plate to change position with the connecting block, driving the rotating plate to rotate around the axis body, and driving the main body of the ceiling lamp to rotate, thereby changing the angle of the lamp head. The whole process is simple, fast and stable.

[0005] The technical solution to achieve the purpose of the utility model is: a ceiling lamp with an easily adjustable lamp head, comprising a mounting tube, the cylindrical outer side wall of the mounting tube is fixedly connected to a box body, and further comprising;

[0006] A rotating mechanism, wherein the rotating mechanism is located in the mounting cylinder;

[0008] In some embodiments, a support plate is fixedly connected inside the installation cylinder, and the two threaded rods are rotatably connected to one side of the support plate.

[0009] In some embodiments, a rotating motor is fixedly connected to one side of the box body, a rotating rod is fixedly connected to the output end of the rotating motor, and one end of the rotating rod passes through one side of the box body and is keyed to one side of the first gear.

[0010] In some embodiments, the bottom of the rotating plate is fixedly connected to a ceiling lamp body, the cylindrical outer side wall of the ceiling lamp body is fixedly connected to two first support blocks, and one side of the two first support blocks is rotatably connected to a connecting rod.
