Description

Technical Field

[0001] This utility model relates to the field of music teaching devices, and in particular to a music stand device for music teaching. Background Technology

[0002] Musical sheet music is a method of recording music using symbols, either printed or handwritten. It is widely used in music education. When teaching strummed or wind instruments, a music stand is usually used to support the sheet music so that the teacher can view and play or play it. Most existing music stands are retractable, which are flexible to open and close, but the structure supporting the sheet music at the top is relatively large and cannot be completely closed. In music teaching, it is necessary to carry music stands, sheet music, instruments, and other teaching aids, which involves a lot of items. A retractable music stand would be better for carrying and storing these items. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1-3 As shown, a music stand device for music teaching includes a telescopic support cylinder 1, a swing arm 3, and a music support column 5;

[0018] The top of the telescopic support cylinder 1 is inserted with an inner core 21. An angle adjustment tightening clamp 11 is installed on the top of the inner core 21. The angle adjustment tightening clamp 11 is equipped with a V-shaped frame tightening clamp 2, which facilitates the adjustment of the overhead angle of the music score. Two swing arms 3 distributed in a V-shape are installed on the V-shaped frame tightening clamp 2. The angle of the V-shaped structure can be adjusted by the V-shaped frame tightening clamp 2, mainly by tightening the bolts 12. This is a general bolt clamping structure, which will not be described further here.

[0019] The end of the swing arm 3 is fitted with a music score support column 5 via a support column bottom clamping clamp 4, and the music score is mainly placed on the music score support column 5;

[0020] The music score support column 5 is provided with a pad groove 7, and a pad rod 6 is rotatably installed on the bottom inner side of the pad groove 7. The pad rod 6 is provided with a stop groove 8, and a retaining strip 9 is rotatably installed on the inner side of the stop groove 8.

[0021] like Figures 1-3 As shown, this utility model also discloses the following more optimized specific structures:

[0022] A fixed ring 17 is fixedly installed at the bottom of the telescopic support cylinder 1. A collar 13 is sleeved on the telescopic support cylinder 1. Several foot rods 15 are hinged to the outer ring surface of the collar 13. Bottom support rods 16 are hinged to the body of the foot rods 15. The end of the bottom support rods 16 is hinged to the fixed ring 17.

[0023] The collar 13 is provided with several ring-shaped threaded holes, and collar bolts 14 are threadedly connected to the ring-shaped threaded holes. The end of the collar bolts 14 presses against the rod of the telescopic support cylinder 1. The collar 13 can be moved up and down and fixed by tightening and loosening the collar bolts 14.

[0024] The telescopic support cylinder 1 is composed of several single cylinders 18 inserted together. Each single cylinder 18 has several cylinder thread holes 19. The telescopic support cylinder 1 can be telescopically stabilized by the cylinder fixing bolts 20 inside the cylinder thread holes 19.

[0025] The outer side of the retaining strip 9 is provided with a limiting protrusion 10, which is used to limit the retaining strip 9 when it is flipped outward to prevent it from flipping too much. The inner side of the retaining strip 9 is provided with an anti-slip pad.

[0026] like Figures 1-3 When the music teaching music stand device shown is being retracted, the telescopic support cylinder 1 is in a retracted state, the music support column 5 and the swing arm 3 are inserted into the inner cavity of the telescopic support cylinder 1, and the bottom foot 15 is in a retracted state, so that the whole device is in a short rod state for storage or retrieval.

[0027] When in use, press down the collar 13 to open the foot rod 15 to the specified angle, and fix the collar bolt 14. After fixing, it can be supported on the ground. Then, extend the telescopic support cylinder 1 appropriately according to the height of the instrument and the music teacher and fix it. Then, pull out the music score support column 5 and the swing arm 3, and fix the two swing arms 3 after unfolding. The pad rod 6 on the music score support column 5 flips out to support the music score, and the locking strip 9 flips out to lock the side of the music score.
