Description

Technical Field

[0001] This utility model relates to the field of sound effect reflector angle adjustment technology, and in particular to a mechanical angle adjustment device for stage sound effect reflectors. Background Technology

[0002] Stage acoustic reflectors are key equipment in stage acoustic design. Their core function is to improve the clarity, fullness, and spatiality of sound quality by optimizing the sound wave reflection path.

[0003] Stage sound effect reflectors require angle adjustment during use and storage. Traditionally, this adjustment is mostly manual. For example, when folding two movable reflectors onto a fixed one, each reflector must be manually rotated to fit against the fixed one. For large reflectors, manual angle control is laborious and cannot achieve coordinated adjustment between the two reflectors, resulting in low efficiency. Therefore, this invention proposes a mechanical angle adjustment device for stage sound effect reflectors to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a mechanical angle adjustment device for a stage sound effect reflector. This device utilizes an adjustment rod rotatably mounted inside the adjustment base, with first bevel gears at both ends and a second bevel gear meshing with the first bevel gears at the lower end of a rotating shaft. When the adjustment rod is driven to rotate by a motor, the meshing of the first and second bevel gears drives the two rotating shafts to rotate in opposite directions, thus controlling the movable sound effect reflector to rotate synchronously. This results in a highly interconnected adjustment process, solving the problem of cumbersome operation caused by single-adjustment methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mechanical angle adjustment device for a stage sound effect reflector includes an adjustment base, a fixed sound effect reflector, and a movable sound effect reflector. The fixed sound effect reflector is detachably installed on the top of the adjustment base, and the movable sound effect reflector is disposed on both sides of the fixed sound effect reflector. The movable sound effect reflector is rotatably installed with the adjustment base via a rotating shaft. The device is characterized in that: the adjustment base has symmetrically arranged supports inside, and an adjustment rod is rotatably mounted on each of the two supports. Each end of the adjustment rod is provided with a first bevel gear. The lower end of the rotating shaft extends into the adjustment base and is provided with a second bevel gear, which meshes with the first bevel gear. The adjustment rod is driven to rotate by a motor. The top of the adjustment base is provided with a mounting base, and the mounting base is provided with a limiting and fixing mechanism. The fixed sound effect reflector is pressed and fixed to the top of the adjustment base by the limiting and fixing mechanism.

[0006] A further improvement is that a first gear is installed at the output end of the motor, and a second gear is installed on the adjusting rod, with the second gear meshing with the first gear.

[0007] A further improvement is that the top of the adjustment base is provided with a fixing groove, and the lower end of the fixed sound effect reflector is inserted into the fixing groove.

[0008] A further improvement is that the limiting and fixing mechanism includes a limiting and fixing plate and a screw. The screw is rotatably provided inside the mounting base. The limiting and fixing plate is slidably connected to the inner wall of the mounting base. The bottom of the limiting and fixing plate is provided with a threaded hole, and the upper end of the screw is connected to the threaded hole.

[0009] A further improvement is that the limiting and fixing plate has an L-shaped structure, and the lower outer wall of the mounting base is provided with a mounting groove, which is connected to the interior of the mounting base.

[0010] A further improvement is that a worm gear is installed at the lower end of the screw, a worm is rotatably provided inside the mounting groove, the worm meshes with the worm gear, and one end of the worm extends out of the side wall of the mounting groove and is provided with a knob.

[0011] The beneficial effects of this utility model are as follows: This utility model rotates and installs the movable sound reflector with the adjustment base via a rotating shaft. A first bevel gear is set at both ends of the adjustment rod that is rotatably set inside the adjustment base, and a second bevel gear that meshes with the first bevel gear is set at the lower end of the rotating shaft. When the adjustment rod is driven to rotate by the motor, the first bevel gear and the second bevel gear mesh and drive the two rotating shafts to rotate in opposite directions, thereby controlling the movable sound reflector to rotate synchronously. The adjustment process has high linkage and solves the problem of cumbersome operation caused by single adjustment. Attached Figure Description
