Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument stands, in particular to a zither stand with adjustable height and tilt angle. Background Art

[0002] Chinese Patent No. 201720277852.4 discloses a guzheng stand with convenient angle adjustment. By controlling the telescopic button with the foot or hand to control the extension and retraction of the electric telescopic legs, the rear side of the guzheng placement stand is controlled to rise or fall, thereby achieving angle adjustment of the guzheng stand. In actual use, there are problems that can be further optimized: only the angle can be adjusted, not the height. People who play the guzheng vary greatly in height, gender, age, etc., and have different requirements for the height of the guzheng. Adjusting the angle alone cannot meet different needs.

[0006] An angle adjustment hole is provided on the rear side of the adjustment frame, and the angle adjustment hole is arranged on an arc track with the center of the height adjustment hole on the front side as the center of the circle. A second bolt hole corresponding to the angle adjustment hole is provided on the support frame, and the angle adjustment hole and the second bolt hole are detachably connected by a second handle bolt.

[0007] Furthermore, multiple groups of angle adjustment holes are provided, and each group of angle adjustment holes corresponds to a height adjustment hole on the upper portion of the front side; when only the height is adjusted, the second handle bolt is not connected between the angle adjustment hole and the second bolt hole, and the height adjustment holes at different heights on both sides are connected to the corresponding first bolt holes through the first handle bolt to achieve height adjustment;

[0008] When adjusting the angle of the support frame, one of the height adjustment holes corresponding to the angle adjustment holes on the front side is connected to the support frame through the first bolt, and the first handle bolt is not connected between the height adjustment hole on the rear side and the support frame. The corresponding group of different angle adjustment holes are connected to the second bolt hole through the second handle bolt to achieve angle adjustment.

[0031] like Figure 1-10 As shown, the utility model includes left and right support frames 1, with reinforced connecting plates 2 connected between the support frames 1, and height and angle adjustable adjustment frames 3 are provided on the outside of the support frames 1. The adjustment frames 3 on both sides are symmetrically arranged, and the upper ends of the adjustment frames 3 on both sides are support surfaces 4 for supporting the guzheng, and protrude from the support frames 1. The support surfaces 4 are provided with upwardly protruding limiting ridges 5 on both sides along the width direction of the support frames 1, and the guzheng in an inclined state is limited by the limiting ridges 5.

[0032] A row of height adjustment holes 6 are respectively provided on both sides of the adjustment frame 3, and the height adjustment holes 6 on both sides are symmetrically arranged. The support frame 1 is provided with first bolt holes 7 corresponding to the height adjustment holes 6 on both sides. The height adjustment holes 6 and the first bolt holes 7 on the corresponding sides are detachably connected through the first handle bolt 8.

[0033] Angle adjustment holes 9 are provided on the rear side of the adjustment frame 3, and there are multiple groups of angle adjustment holes. This embodiment is specifically described by taking three groups of angle adjustment holes as an example, wherein the first group is located on an arc track A with the center of the uppermost height adjustment hole 6 on the front side as the center of the circle, the second group is located on an arc track B with the center of the second uppermost height adjustment hole on the front side as the center of the circle, and the third group is located on an arc track C with the center of the third uppermost height adjustment hole on the front side as the center of the circle.

[0034] The support frame 1 is provided with a second bolt hole 10 corresponding to the angle adjustment hole 9. The angle adjustment hole 9 and the second bolt hole 10 are detachably connected by a second handle bolt 11. Furthermore, each group of angle adjustment holes 9 corresponds to one second bolt hole 10. When the three groups of second bolt holes have the same intersection point during rotation, the three groups of angle adjustment holes 9 can also correspond to one second bolt hole 10.

[0035] When the utility model is actually used, when only the height is adjusted, the second handle bolt 11 is not connected between the angle adjustment hole 9 and the second bolt hole 10, and the height adjustment holes 6 on both sides that do not pass through the height are connected to the first bolt hole 7 through the first handle bolt 8 to achieve height adjustment.

[0036] When adjusting the angle and height at the same time, first remove the first handle bolt 8 between the rear height adjustment hole 6 and the support frame 1, select one of the three height adjustment holes 6 on the uppermost front side and thread it with the corresponding first bolt hole 7 through the first handle bolt 8, rotate the adjustment frame 3, and adjust the angle of the adjustment frame 3. After the adjustment is completed, connect the corresponding group of angle adjustment holes 9 and the second bolt holes 10 through the second handle bolt 11 to achieve angle adjustment.

[0037] In this embodiment, when the angle is adjusted, when the height adjustment hole on the uppermost side of the front side is threadedly connected with the corresponding first bolt hole 7 through the first handle bolt 8, the corresponding group is provided with three-level angle adjustment holes. Figure 11-13 The diagram shows the corresponding tilt angles of the adjustment frame 3 at different gears, with an angle adjustment range of 5-15°. When the second height adjustment hole on the upper front side is threadedly connected to the corresponding first bolt hole 7 through the first handle bolt, the corresponding group is provided with three angle adjustment holes. Figure 14-16It shows the corresponding tilt angles of the adjustment frame at different gears, and the angle adjustment range is 5-15 degrees; when the third height adjustment hole on the upper front side is threadedly connected to the corresponding first bolt hole 7 through the first handle bolt, the corresponding group is provided with five angle adjustment holes, Figure 16-21 The corresponding tilt angles of the adjustment frame at different gear positions are shown, and the angle adjustment range is 5-30°.
