[0002] Wind instruments refer to a type of musical instrument that produces sound by the vibration of air in the tube, and can be divided into blow hole wind instruments, single reed wind instruments, double reed wind instruments, and lip reed wind instruments. Currently, common wind instruments often use a bracket with multiple symmetrical inclined grooves or symmetrical hooks to support the two ends of the wind instrument to achieve simple horizontal placement. However, in actual use, the horizontal placement structure is not only unstable and easy to shake, but also the distance between the symmetrical inclined grooves or symmetrical hooks is fixed, which makes it difficult to adapt to wind instruments of different lengths.

A rotation adjustment component 37 is provided inside the square box 34 to control the rotation of the rotation shaft 35; one end of the U-shaped frame 31 is close to the side of the support plate 2, and the other end is away from the side of the support plate 2, and the end of the U-shaped frame 31 away from the side of the support plate 2 is hinged to one end of the flip plate 32, and a support column 312a is fixedly provided at one end of the U-shaped frame 31 close to the side of the support plate 2 to support the other end of the flip plate 32; the square box 34 is located on one side of the U-shaped frame 31 and slides horizontally; the insertion rod 33 and the support rod 36 are perpendicular to each other in the horizontal plane, and the support rod 36 is located below the insertion rod 33 in the vertical direction, and the tip of the insertion rod 33 points to the support rod 36. The surfaces of the insertion rod 33 and the support rod 36 are coated with a rubber protective coating, which can increase the friction between the wind instrument and the insertion rod 33 and the support rod 36, improve the fixing stability of the wind instrument, and effectively prevent the insertion rod 33 and the support rod 36 from wearing the surface of the wind instrument to ensure the appearance of the wind instrument is intact.

[0023] like Figure 2 , Figure 3 As shown, the U-shaped frame 31 includes a U-shaped plate 311, a U-shaped rib 312 fixed to one side of the U-shaped plate 311, one end of the flip plate 32 is hingedly connected to the U-shaped rib 312, and a support column 312a is fixedly connected to the U-shaped rib 312; a hinge shaft 312c is fixedly arranged on the U-shaped rib 312, and a hinge hole 321 for the hinge shaft 312c to rotate through is provided on one side of the flip plate 32; a pair of through holes 311a are provided on one side of the U-shaped plate 311 close to the support plate 2, a bolt 311b passing through the through hole 311a is movably inserted on the support plate 2, and a nut 311c is threadedly connected to the bolt 311b to fix the U-shaped plate 311 on the support plate 2. By adopting the connection structure of the U-shaped plate 311, the support plate 2 and the flip plate 32, the stability of the fixed positioning of the wind instrument by the structure can be effectively guaranteed. Among them, a support column 2 312b is also provided on the U-shaped retaining edge 312. The support column 2 312b and the support column 1 312a are parallel to each other and are located below the hinge shaft 312c, which can not only limit the flipping range of the flip plate 32, but also provide certain support when necessary; the flip plate 32 is located on one side of the insertion rod 33 and is fixedly provided with a handle 322 in parallel, and the handle 322 is away from the rotation center of the flip plate 32, which can facilitate the staff to quickly flip the flip plate 32.

By adopting the above-mentioned limiting groove 361, the insertion rod 33 on the flip plate 32 can be matched to further limit the movement of the positioning wind instrument, so as to improve the stability of the structure in fixing the wind instrument.

[0025] like Figure 4As shown, the rotation adjustment assembly 37 includes a worm wheel 371 fixedly mounted on the rotating shaft 35, a driving shaft 372 whose two ends rotate and penetrate the two side walls of the square box 34, a worm 373 fixedly mounted on the driving shaft 372 and meshing with the worm wheel 371, and a knob 374 fixedly connected to the driving shaft 372 and extending out of one end of the side wall of the square box 34. By adopting the above-mentioned rotation adjustment assembly 37, when the rotating shaft 35 needs to rotate, first manually twist the knob 374 to rotate the driving shaft 372, then the driving shaft 372 drives the worm 373 to rotate, so that the worm 373 meshes with the transmission worm wheel 371, and finally the worm wheel 371 drives the rotating shaft 35 to rotate, so that the rotating shaft 35 drives the support rod 36 to rotate eccentrically. Among them, the transmission structure of the worm wheel 371 and the worm 373 can not only save the internal space of the rotating box, but also use the front and rear self-locking rotating shaft 35 to stably maintain the height distance from the top of the support rod 36 to the axis of the rotating shaft 35.

[0026] like Figure 1 As shown, a top plate 4 and a bottom plate 5 are fixedly installed in the top and bottom frames of the rectangular parallelepiped frame 1, respectively, a glass side plate 6 is fixedly installed in the left and right frames of the rectangular parallelepiped frame 1, respectively, a pair of glass double-opening doors 7 is installed in the front frame of the rectangular parallelepiped frame 1, the sides of the two glass double-opening doors 7 that are away from each other are close to the left and right sides of the rectangular parallelepiped frame 1, respectively, and are hinged to the side walls of the rectangular parallelepiped frame 1 through hinges, and the sides of the two glass double-opening doors 7 that are close to each other are close to the middle of the rectangular parallelepiped frame 1, and handles 71 are fixedly installed. By adopting the above-mentioned glass side plates 6 and glass double-opening doors 7, not only can dust and moisture be effectively prevented, but also it is convenient for exhibition viewing.

[0027] The working principle of this embodiment:

[0028] When it is necessary to place a wind instrument, first manually pull the handle 71 to open the glass double-opening door 7 on the front of the rectangular frame; then hold the grip 322 to flip the flip plate 32 on the U-shaped frame 31 out from between the hinge shaft 312c and the support plate 2; then align one end of the wind instrument with the truncated cone-shaped insertion rod 33 in the middle of the flip plate 32, and make the insertion rod 33 relatively inserted into the hole at one end of the wind instrument, and then hold the grip 322 again to flip the flip plate 32 back between the hinge shaft 312c and the support plate 2, and the wind instrument will also flip with it, and the other end will just rest on the support rod 36; if the top height of the support rod 36 is too high or too low at this time, resulting in the flip plate 32 being unable to be horizontal or the other end of the wind instrument is suspended in the air, the rotation of the rotating shaft 35 can be adjusted and controlled by the rotating adjustment component 37. Due to the eccentric connection between the rotating shaft 35 and the support rod 36, During the rotation of the support rod 36, the top end of the support rod 36 will move vertically closer to or farther away from the axis of the rotation axis 35 of the rotation axis 35, thereby achieving height adjustment of the top end of the support rod 36; if the support rod 36 is too far or too close to the U-shaped frame 31 at this time, and the other end of the wind instrument cannot reach the support rod 36 or exceeds the support rod 36, the square box 34 can be manually controlled to slide relative to the support plate 2 to adjust the distance between the support rod 36 and the U-shaped frame 31, thereby cooperating with the above-mentioned rotation adjustment component 37 for controlling the eccentric rotation of the support rod 36 to adapt to more wind instruments of different lengths and outer diameters; finally, when the end of the flip plate 32 away from the hinge shaft 312c is placed on the support column 1 312a, and the other end of the wind instrument is successfully placed in the limiting groove 361 on the side of the support rod 36, the wind instrument will be completely and stably fixed on the support plate 2 and cannot shake easily.
