Description
Technical Field
[0001] The utility model belongs to the technical field of music arranging tables, in particular to a music arranging table for composing music. Background Art
[0002] An arranger desk is a professional device used for music creation and production, usually including a console with a sequencer, effects, etc., as well as one or more monitor speakers and headphones. An arranger desk allows music producers to conveniently control the music production process and provide high-quality sound monitoring.
[0003] Generally, a music arrangement table is provided with a shelf for placing music scores, but most of the music score shelves are fixed. When a person places the music scores on the music score shelf, the person cannot adjust the direction of the music score shelf according to the observation angle, making it inconvenient for the person to observe the music scores on the music score shelf. In addition, when the music arrangement table is in use, the height of the music arrangement table is fixed, which causes the phenomenon of inappropriate height when people of different heights use the music arrangement table. In view of this, we propose a music arrangement table for composing music. Utility Model Content

Under the action of meshing, the bevel gear 2 drives the bevel gear 1 to rotate, and the rotation of the bevel gear 1 drives the threaded rod to rotate. Under the action of the thread, the threaded rod drives the sliding block to move in the sliding groove, and at the same time, the sliding block drives the power rod to rotate. The rotation of the power rod on the U-shaped leg will drive the table top to move upward, and at the same time, the table top will drive the four sliding legs to move upward in the corresponding moving grooves. Under the action of the four sliding legs and the two U-shaped legs, it can ensure that the table top will not tip over, and ensure that the person can adjust the height of the table top according to their height, so as to facilitate the use of the person.
