Description

Technical Field

[0001] This utility model relates to the technical field of music education, and in particular to the technical field of a music score display device. Background Technology

[0002] Musical notation is a method of recording music using symbols, either printed or handwritten. Different cultures and regions have developed different notation methods. Notation can be divided into two main categories: notation of pitch and notation of fingering. Staff notation, numbered musical notation, and braille all belong to musical notation for notation of pitch, while tablature for guitar and tablature for guqin belong to musical notation for notation of fingering. When conducting music teaching, display devices are needed to place the musical scores to facilitate teaching and learning.

[0003] A folding music stand with application (patent) number CN201820332160.X includes a support and a music stand. The music stand is detachably mounted on the support, which is an adjustable and telescopic support. The music stand is a folding music stand, which is composed of several support plates. Each pair of support plates is connected by hinges, and the support plates are connected in pairs to form the music stand. Since the music stand is composed of several support plates connected in pairs by hinges, when more support plates are used, although the width of the support plates decreases, the overall thickness after folding increases, and more hinges are used, increasing costs. When fewer support plates are used, although the overall thickness after folding decreases, the width of the support plates increases. It can be seen that the volume of the music stand after folding is affected by the support plates. Therefore, the music stand of this folding music stand still has a large volume after folding. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a music score display device that can be folded into a small size and is easy to carry.

[0005] To achieve the above objectives, this utility model proposes a music score display device, comprising a lower support, an upper support, a flexible sheet, and two support components. The flexible sheet and the two support components are disposed between the lower support and the upper support. The support components are located on the back of the flexible sheet. The upper support pulls the flexible sheet taut under the action of the support components. The support components include a lower arm and an upper arm. The lower end of the lower arm is elastically hinged to the lower support, and the upper end of the lower arm is hinged to the lower end of the upper arm. The upper end of the upper arm is hinged to the upper support.

[0006] Preferably, the flexible sheet is made of mesh fabric.

[0007] Preferably, the flexible sheet is provided with a number of spaced-apart support ribs arranged sequentially from top to bottom.

[0008] Preferably, the lower end of the lower support arm is provided with a connecting shaft, and a connecting lug fixed on the lower support is rotatably provided on the connecting shaft. A torsion spring is sleeved on the connecting shaft between the connecting lug and the lower support arm, and the two ends of the torsion spring are respectively connected to the connecting lug and the lower support arm.

[0009] Preferably, the lower support arm is provided with a hook in the middle, and the upper support is provided with a hanging head for the hook to be hung.

[0010] Preferably, the lower support is mounted on the telescopic adjustment rod via a universal adjustment assembly, and the lower end of the telescopic adjustment rod is provided with a tripod.

[0011] Preferably, the universal adjustment assembly includes a ball head and an annular ball seat. The ball head is provided with an annular ball seat that mates with it. The annular ball seat has an opening, and a screw is provided at the opening of the annular ball seat for adjusting the distance between the two ends of the opening.

[0012] Preferably, the front end of the ball head is provided with a connecting seat, the connecting seat is provided with a plug hole, and the lower end of the lower support is provided with a plug body that passes through the plug hole.

[0013] Preferably, the telescopic adjusting rod includes a sleeve and a telescopic rod inserted inside the sleeve. The sleeve is provided with a threaded hand-tightening bolt, which is tightened against the telescopic rod to fix it in place.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a flexible sheet and two support components at the front and back between the lower support and the upper support. The support components are located on the back of the flexible sheet. By extending the support components, the upper support moves away from the lower support. The lower support pulls the flexible sheet flatten and tightens it. The flexible sheet can be folded at will, which basically does not affect the volume of the spectrum stage after folding. Compared with the prior art, it can be folded into a small volume, which is easy to carry and reduces weight.

[0015] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0020] See Figure 1 , Figure 2 , Figure 3 This utility model discloses a music score display device, comprising a music stand consisting of a lower support 1, an upper support 2, a flexible sheet 3, and two support components 4. The flexible sheet 3 and the two support components 4 are disposed between the lower support 1 and the upper support 2. The support components 4 are located on the back of the flexible sheet 3. The upper support 2 pulls the flexible sheet 3 to tighten under the action of the support components 4. The support components 4 include a lower support arm 41 and an upper support arm 42. The lower end of the lower support arm 41 is elastically hinged to the lower support 1, and the upper end of the lower support arm 41 is hinged to the lower end of the upper support arm 42. The upper end of the upper support arm 42 is hinged to the upper support 2.

[0021] The flexible sheet 3 is made of mesh fabric.
