Description

Technical Field

[0001] The invention relates to the technical field of cello accessories, in particular to a cello ground supporting device which prevents wear. Background Art

[0002] The cello is an essential alto or bass string instrument in the orchestra, and is a very popular solo instrument. In orchestral music, the cello often plays very melodic phrases, and also shares the bass part of the harmony with the double bass. It has a rich and full timbre, a cheerful character, is good at playing lyrical melodies, and expresses deep and complex emotions. It also shares the bass part of the harmony with the double bass, and is known as the "Lady of Music". When the cello is played, the long nails at the bottom are placed obliquely on the ground, which can easily scratch the ground, and the cello is easy to slip.

[0003] There are two existing methods to solve the above problem: 1. Set a suction cup at the bottom of the anti-skid mat to make the anti-skid mat adsorb on the ground, and insert the long nails at the bottom of the cello into the groove at the top of the anti-skid mat. This kind of anti-skid mat is only suitable for smooth ground, and after long-term use, the anti-skid mat will still move on the smooth ground; 2. Use Figure 3 The anti-skid belt shown in the figure includes a traction belt and traction rings and anti-skid plates respectively fixed at both ends of the traction belt. One end of the anti-skid belt is placed at the bottom of the seat support leg, and the long nails at the bottom of the cello are inserted into the grooves at the top of the anti-skid plate. When the anti-skid belt is used, the anti-skid plate moves on both sides in the horizontal direction. Both of the above devices cannot well limit the long nails at the bottom of the cello, which has a great impact on the performance of the performer.

[0004] Therefore, it is necessary for us to propose a cello ground support device that prevents wear and tear to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the long nails at the bottom of the cello are displaced during playing and affect the performance of the performer, and to propose a cello ground support device that prevents wear.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A cello support device for preventing wear and tear comprises a bottom plate and a movable plate distributed along the length direction, wherein the ends of the bottom plate and the movable plate close to each other are plugged in the vertical direction, a rotating ball is installed on the top of the end of the movable plate away from the bottom plate, a storage channel is provided on the top of the end of the bottom plate away from the movable plate, and clamps with the same structure are provided on both sides directly above the storage channel, grooves are provided on the side walls of the two clamps close to each other, a seat foot is provided between the two grooves, and the bottom of the seat foot is located in the storage channel.

[0008] Preferably, a limiting groove is provided at one end of the bottom plate close to the movable plate, inner teeth are provided on the inner walls on both sides of the limiting groove, a plug-in block is provided at one end of the movable plate close to the bottom plate, outer teeth are provided on the edges of both sides of the plug-in block, the outer teeth are matched with the inner teeth, and the distance between the bottom plate and the movable plate away from the two side walls can be adjusted, thereby realizing the function of adjusting the position of the long nails at the bottom of the cello.

[0009] Preferably, a mounting plate is fixed to the top of the base plate by a screw, an adjustment handle is threadedly connected to the side wall of the mounting plate, and a side wall of the clamping plate away from the groove is rotatably connected to the adjustment handle. By rotating the adjustment handle, the distance between the two clamping plates can be adjusted, thereby further fixing the seat legs by the clamping plates, and fixing the entire device and the seat legs.

[0010] Preferably, the top interface of the groove is one of an arc, a rectangle, and a right-angled trapezoid, which is suitable for fixation between seat legs of different shapes, and the bottom of the bottom plate and the bottom of the movable plate are both glued with anti-slip pads.

[0011] Preferably, the top of the movable plate is pinned with a mounting block, the top of the mounting block is fixed with a spherical limiting plate through a bracket, the bottom of the rotating ball is rotatably connected to the limiting plate, and the top of the rotating ball is provided with a limiting hole for inserting the long nails at the bottom of the cello. The rotating ball is a wearing part, which facilitates the replacement of the rotating ball.

[0012] The beneficial effects of the present invention are:

[0013] 1. The device is firmly fixed to the seat legs by adjusting the splint and turning the handle, and the position of the long nails at the bottom of the cello is adjusted by adjusting the distance between the bottom plate and the movable plate. The fixation is firm, and the bottom plate and the movable plate are not easy to move, which plays a good role in limiting the long nails at the bottom of the cello. The bottom of the long nails will not move with the movable plate during the performance of the cello, and will not affect the performance of the performer;

[0014] 2. The device has a simple structure, reasonable design, and is easy to assemble. The overall structure is detachable, which takes up little space and is easy to disassemble and carry. The device and the seat legs are fixed by a splint. The bottom of the device is equipped with an anti-slip pad, which has good anti-slip performance.

[0015] 3. When a player plays the cello, his body will slightly change with the ups and downs of the music. The design of the rotating head enables it to rotate with the displacement of the cello, making the cello move more smoothly and reducing the wear of the long spikes at the bottom of the cello. The rotating ball is low-cost and is a vulnerable part, so it is easy to replace. BRIEF DESCRIPTION OF THE DRAWINGS
