Description

Music stand

Technical Field

The utility model belongs to the technical field of music stand design, and particularly relates to a music stand.

Background

The score is usually placed on a score holder for viewing by a player when in use. The height of the music score bracket can be adjusted to change the height of the music score placing table so as to adapt to the heights of different users; the existing music score bracket generally comprises a base and a supporting rod supporting plate, wherein the supporting rod is connected with the base and the supporting plate; the existing common music score bracket has the following defects: the rotation angle of the music score placing table is inconvenient to adjust, and the music score placing table can be rotated under the action of self gravity and music score gravity after long-time use, so that the use of a user is affected. In other occasions, more music scores or other articles need to be carried, the traditional music score placing rack does not have a large number of positions for placing the music scores, and only the music scores or other articles can be placed on the ground, so that dirt is easily caused, and the music scores are very inconvenient to take and place; and the front-back distance of the music score placing table cannot be adjusted, so that the bottom support frame is easy to interfere with the standing position of a player, and the performance of the player is influenced.

For example, the prior art describes: the patent number 202120569625.5 discloses a multifunctional music stand, which comprises a support frame 1 and a music stand 2 which is arranged on the support frame 1 in an inclined manner, wherein a tripod support 15 is arranged at the bottom end of the support frame 1. The tripod support below the music stand can limit the walking or performance of a user when in use, and the support is easy to pedal when the performer walks due to the fact that the music stand is arranged right above the triangular support. It is therefore desirable to provide a music stand that can be extended and retracted forward to avoid stepping on the support during performance. Meanwhile, the technical proposal does not record the technical characteristics of the unused music score rack, so that a structure for temporarily placing redundant music scores is also required to be correspondingly arranged.

Meanwhile, a vocal music training music stand with a patent number of 202120738925.1 is described in the prior art, and a vocal music training music stand is described. The vocal music training music stand includes: mesa, receiver, anti-drop mechanism, supporting mechanism and light, the mesa with the receiver is connected, the size of mesa is less than the size of receiver, the receiver is used for accomodating the mesa, the mesa upside is provided with anti-drop mechanism and light, supporting mechanism with the receiver is connected. The music stand for vocal training can be used for accommodating a table top, providing a light source and fixing music scores. The music stand is provided with the storage box in the prior art, but the opening direction of the storage box is positioned at the rear side of the table top, so that the music is required to be taken and placed around the rear side during performance, the music stand is inconvenient, and the storage box is of a middle concave structure, so that the music stand is not beneficial to temporarily taking and placing the music; meanwhile, the prior art does not describe a music stand capable of moving back and forth, and interference is easy to occur between a user and the supporting legs, so that the user can tread the supporting legs easily, and a collision phenomenon is caused.

To solve the above problems, we provide a music stand which can adjust the angle of placing a music score and adjust the front and rear positions of the music score placing stand, and can place some unnecessary music score or other articles.
