Description

Technical Field

[0001] The utility model relates to the field of musical instrument storage, in particular to a brass instrument storage device. Background Art

[0002] Brass instruments include trumpets, cornets, flugelhorns, French horns, marching horns, euphoniums, baritone horns, tubas, sun horns, and trombones. Currently, the existing storage methods for brass instruments generally include separate storage and centralized storage:

[0003] Separate storage means placing brass instruments directly in a storage box; for example, the utility model with publication number CN212516525U and publication date February 9, 2021 discloses a wind instrument storage box, which can effectively protect the wind instruments installed inside through the internal cushion and shock-absorbing foam. However, for schools, many brass instruments need to be used at the same time in music classes to meet the needs of students. It is difficult to manage brass instruments in a unified manner using storage boxes. Schools generally stack storage boxes containing brass instruments in storage cabinets or place them on storage racks, which is inconvenient for students to take instruments and takes up a lot of space.

[0004] Centralized storage means that many brass instruments are directly stored in an orderly manner in a large storage device; for example: a brass instrument storage rack with a publication number of CN217822065U and a publication date of November 15, 2022, which clamps the bell of the brass instrument through a clamping component and extends into the bell of the brass instrument through a fixing part, so that the brass instrument will not shake left and right, thereby achieving fixed storage of the brass instrument. However, the storage rack is a single-layer storage form, and the number of brass instruments that can be stored at the same time is limited, and the brass instruments are exposed to the outside and are easily contaminated by dust in the air.

[0005] In summary, the existing brass instrument storage devices have the problems of limited storage quantity, large occupied space, and inconvenient access. Utility Model Content
