[0001] The utility model relates to the technical field of musical instrument placement racks, in particular to a multifunctional musical instrument placement rack. Background Art

[0002] Plucked musical instruments have basically the same external structure, all having a relatively long neck and several strings. Plucked instruments cannot be placed randomly. If placed randomly, they are prone to being bumped and damaged, resulting in problems with intonation. Therefore, plucked instruments require special placement racks. In the Chinese utility model CN214410758U, a portable multifunctional guitar placement rack is disclosed. Through the mutual cooperation between the placement board, the placement plate, the first clamping component and the driving component, during practice, an operator can place the music score through the driving component and the first clamping component, so that during practice, the training personnel can better view the music score. The structure is designed simply and reasonably, the operation is convenient, and it is more practical. However, the portable multifunctional guitar placement rack still has the following problems in use:

[0003] The bottom floor plate of the portable multifunctional guitar placement rack abuts against the tail of the guitar, but it cannot be positioned. It can only be stabilized by clamping the neck of the guitar with the clamping component at the top. The tail of the guitar is prone to swaying left and right. At this time, the stress generated is concentrated at the relatively thin neck of the guitar, which is prone to damage the neck. Moreover, the position of the clamping component is fixed and cannot accommodate guitar-like instruments with different neck lengths. Summary of the Utility Model

Specific embodiments

[0025] The following further describes the present utility model in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0026] Embodiment 1: As Figures 1 to 4 shown, a multifunctional musical instrument placement rack includes a base 1. A rotatable plate 2 with adjustable angle is rotatably connected to the edge of one side of the top of the base 1. A protective panel 3 is fixedly connected to the top of the rotatable plate 2. A neck protection plate 4 is fixedly connected to the center of the top of the protective panel 3. A strip-shaped guiding through hole 5 is opened at the center of one side of the neck protection plate 4. An adjusting lead screw 15 is rotatably connected to the center of the inner wall of the strip-shaped guiding through hole 5. A neck clamping assembly 6 is slidably connected to the inner wall of the strip-shaped guiding through hole 5. The neck clamping assembly 6 is threadedly connected to the adjusting lead screw 15. An adjusting knob 7 is fixedly connected to the top of the adjusting lead screw 15. Connecting shafts 11 are fixedly connected to both sides of the bottom of the back of the protective panel 3. Driving worm gears 12 are rotatably connected to the outer walls of the two connecting shafts 11. Connecting arms 8 are fixedly connected to the bottoms of the two driving worm gears 12. Tail brackets 9 are fixedly connected to one side of the bottoms of the two connecting arms 8. A bidirectional driving worm 13 is rotatably connected to a position near the tops of the two driving worm gears 12 on the back of the protective panel 3. The positive and negative scroll pages on the surface of the bidirectional driving worm 13 are respectively meshed and connected with the two driving worm gears 12.

[0027] As an alternative technical solution of the present utility model, the neck clamping assembly 6 includes a sliding seat 61. Guiding ejector rods 62 are slidably connected to the middle parts of both sides of the sliding seat 61. Clamping plates 63 are fixedly connected to the opposite ends of the two guiding ejector rods 62. Guiding plates 64 are fixedly connected to the tops of the two clamping plates 63. Pressing springs 65 are arranged between one side surface of each of the two clamping plates 63 and the two side surfaces of the inner wall of the sliding seat 61. The pressing springs 65 are sleeved on the outer walls of the guiding ejector rods 62. The length of the pressing springs 65 after reset is greater than the length of the guiding ejector rods 62, so that the two pressing springs 65 can push the two clamping plates 63 to clamp the neck from both sides, facilitating the fixation of the neck.

[0028] As an alternative technical solution of the present utility model, the sum of the lengths of the two guiding ejector rods 62 is less than the left - right length of the sliding seat 61. At the ends of the two guiding ejector rods 62 away from the clamping plate 63, limit baffles 66 are fixedly connected. The diameter of the limit baffle 66 is greater than the diameter of the guiding ejector rod 62. The limit baffle 66 can prevent the guiding ejector rod 62 from detaching from the sliding seat 61.

[0029] As an alternative technical solution of the present utility model, the two guiding plates 64 are arranged to open outwards in an inverted V - shape. The bottoms of the two guiding plates 64 are both at the top of the sliding seat 61. On the opposite sides of the clamping plate 63 facing each other, flexible pads are fixedly connected. The flexible pads can prevent the guitar neck from being bruised. The inverted V - shaped guiding plates 64 facilitate the automatic opening of the clamping plate 63 when the guitar is pushed in, which is convenient for clamping and fixing.

[0030] As an alternative technical solution of the present utility model, the distribution lengths of the positive and negative scroll pages on the surface of the bidirectional transmission worm 13 are equal. The center between the two transmission worm wheels 12 corresponds to the boundary position of the positive and negative scroll pages on the surface of the bidirectional transmission worm 13. Rotating heads are fixedly connected to both ends of the bidirectional transmission worm 13. Thus, when the bidirectional transmission worm 13 rotates, it can drive the two transmission worm wheels 12 to rotate synchronously relatively or in opposite directions, so as to drive the two connecting arms 8 to adjust the angle of opening relative to each other to adapt to guitars and other musical instruments with different widths of the tailpiece.

[0031] As an alternative technical solution of the present utility model, on the top surface of the base 1, on the side away from the side surface of the rotating plate 2, and on the side of the rotating plate 2 away from the base 1, connecting hinges 14 are fixedly connected. On one side of the two connecting hinges 14, a telescopic rod 10 is fixedly connected. The two ends of the telescopic rod 10 are respectively rotationally connected to the base 1 and the rotating plate 2 through the two connecting hinges 14. The telescopic rod 10 includes a threaded sleeve and threaded rods thread - connected to both sides of the inner wall of the threaded sleeve. The ends of the two threaded rods away from the threaded sleeve are respectively rotationally connected to the base 1 and the rotating plate 2. Thus, by rotating the threaded sleeve, the two threaded rods can be driven to expand or contract synchronously outwards or inwards, and then the rotating plate 2 is pushed to adjust the angle, achieving the purpose of facilitating the adjustment of the support angle.

[0032] A multifunctional musical instrument rack has the following working principle:

[0033] 1) The tailpiece brackets 9 at the bottoms of the two connecting arms 8 can support the tailpiece from both sides at the bottom of the tailpiece. By separating the two clamping plates 63, the guitar neck can be clamped.

[0034] 2) By rotating the bidirectional transmission worm 13, the two transmission worm wheels 12 can be driven to rotate simultaneously, and then the two connecting arms 8 are driven to adjust the angle of opening relative to each other to adapt to guitars and other musical instruments with different widths of the tailpiece.

[0035] 3) By rotating the adjusting lead screw 15 to adjust the height of the neck clamping assembly 6, the necks of different lengths can be accommodated.

[0036] In summary, for this multi-functional musical instrument rack, the tailpiece brackets 9 at the bottoms of the two connecting arms 8 can hold the tailpiece from both sides at the bottom of the tailpiece, restricting the degrees of freedom of the tailpiece in the left-right and downward directions, thereby improving stability, making the tailpiece not prone to shaking, reducing damage to the neck. By rotating the bidirectional drive worm 13, the two drive worm wheels 12 can be driven to rotate simultaneously, and then the two connecting arms 8 can be driven to adjust the angle of mutual opening to accommodate musical instruments such as guitars with different tailpiece widths. At the same time, by rotating the adjusting lead screw 15 to adjust the height of the neck clamping assembly 6, necks of different lengths can be accommodated, so as to adapt to various plucked string instruments of different sizes, such as pipa, guitar, ukulele, etc.
