Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a beam lamp with a locking function. Background Technology

[0002] Stage lighting can effectively enhance the stage effect. Stage lights are commonly used stage lighting equipment, which are placed around the stage, with beams of light shining onto the stage in multiple directions to create stage lighting effects.

[0003] As shown in patent documents such as CN205859898U, existing stage moving head lights mainly consist of three parts: the lamp body, the bracket, and the base. The lamp body is rotatably mounted on the bracket, and the bracket is rotatably mounted on the base. The bracket has a drive and transmission structure inside, which can drive the lamp body to swing relative to the bracket. In order to prevent damage to its components or malfunction during transportation and handling, a locking part is usually provided. The locking part limits the rotation axis between the lamp body and the bracket to lock the position of the lamp body and the bracket. However, the existing locking parts generally use a flexible pin structure, such as a ball screw, which has a complex structure, short service life, and also produces a lot of noise during operation.
