Generally, the range of an 88-key piano is from 27.5Hz to 4186.01Hz, and that of a 108-key piano is up to 7902.13Hz, which almost covers all the musical sounds in the musical system. It is one of the instruments with the widest range of sounds. The action is an important component of the action mechanical system, and the linkage in the action is an important component connecting the keyboard and the hammer.

[0003] In actual use by personnel in this field, piano action linkages are mostly fixed by glue or other hard methods. After being damaged and disassembled, the original position is damaged, which makes it inconvenient for the staff to disassemble and reinstall after the damage. Therefore, a piano action linkage is proposed to solve the above problem. Utility Model Content

[0012] The utility model is beneficial in that:

[0013] 1. The utility model directly inserts the arc tooth plate into the slot, and then the teeth of the arc tooth plate contact the teeth of the arc tooth limit plate. Since the arc tooth plate is in arc surface contact, when the arc tooth plate moves downward, the arc tooth limit plate cannot block the arc tooth plate, but is pushed by the arc tooth plate to compress the first spring until the arc tooth plate is inserted into the bottom of the slot. When the arc tooth plate moves upward, the teeth are in contact with the plane, so the arc tooth plate can be limited, thus completing the installation of the linkage body, thereby achieving the effect of easy fixation;

When disassembling the linkage body, it is only necessary to pull the movable rod to drive the arc tooth limit plate to separate from the arc tooth plate, so that the arc tooth plate loses its restriction. At the same time, the movable rod drives the connecting rod to move and move it out of the slot, so that the support plate loses its restriction. Then the second spring restores its deformation and pushes the arc tooth plate out of the slot through the support plate. In this way, the arc tooth plate can be directly popped out for easy disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] During operation, the arc tooth plate 2 is directly inserted into the interior of the slot 4, and then the teeth of the arc tooth plate 2 contact with the teeth of the arc tooth limit plate 502. Since it is an arc surface contact, when the arc tooth plate 2 moves downward, the arc tooth limit plate 502 cannot block the arc tooth plate 2, but is pushed by the arc tooth plate 2 to compress the first spring 503 until the arc tooth plate 2 is inserted into the bottom of the slot 4. When the arc tooth plate 2 moves upward, the tooth plane contacts, so the arc tooth plate 2 can be limited, thereby completing the installation of the linkage body 1.

[0026] Further, the easy-to-disassemble component 6 includes a support plate 601, a second spring 602, a slot 603 and a connecting rod 604. The support plate 601 is movably connected to the inside of the slot 4, the second spring 602 is fixedly connected to the bottom of the support plate 601, the slot 603 is opened on one side of the support plate 601, and the connecting rod 604 is movably inserted into the inside of the fixing seat 3, and the connecting rod 604 is matched with the slot 603;

[0027] During operation, when the arc tooth plate 2 is inserted into the slot 4, it will press down the support plate 601, which will compress the second spring 602. When disassembling the linkage body 1, you only need to pull the movable rod 501 to drive the arc tooth limit plate 502 to separate from the arc tooth plate 2, so that the arc tooth plate 2 loses its restriction. At the same time, the movable rod 501 drives the connecting rod 604 to move, so that it moves out of the inside of the card slot 603, so that the support plate 601 loses its limit, and then the second spring 602 restores its deformation, and pushes the arc tooth plate 2 to move out of the inside of the slot 4 through the support plate 601, so that the arc tooth plate 2 can be directly popped out, which is convenient for disassembly.

[0028] Further, the teeth of the arc-tooth plate 2 are bottom arc-shaped, and the teeth of the arc-tooth limit plate 502 are top arc-shaped;

[0029] This makes it easier for the teeth to work together when working.

[0030] Furthermore, a section of the movable rod 501 extends to the outside of the fixed seat 3, and one end of the movable rod 501 located outside the fixed seat 3 is fixedly connected to a handle 7;

[0034] Furthermore, the support plate 601 is made of magnets, and the arc tooth plate 2 is magnetically connected to the support plate 601;

[0035] During operation, the arc tooth plate 2 can be adsorbed in this way, making the installation more secure.

[0036] Working principle: When installing the linkage body 1, the arc tooth plate 2 is directly inserted into the interior of the slot 4, and then the teeth of the arc tooth plate 2 are in contact with the teeth of the arc tooth limit plate 502. Since it is an arc surface contact, when the arc tooth plate 2 moves downward, the arc tooth limit plate 502 cannot block the arc tooth plate 2, but is pushed by the arc tooth plate 2 to compress the first spring 503 until the arc tooth plate 2 is inserted into the bottom of the slot 4. When the arc tooth plate 2 moves upward, the tooth plane is in contact, so the arc tooth plate 2 can be limited, and the installation of the linkage body 1 is completed. When the arc tooth plate 2 is inserted into the slot 4, the support plate 601 will be pressed down, which will compress the second spring 602. When disassembling the linkage body 1, it is only necessary to pull the movable rod 501 to drive the arc tooth limit plate 502 to separate from the arc tooth plate 2, so that the arc tooth plate 2 loses its restriction. At the same time, the movable rod 501 drives the connecting rod 604 to move, so that it moves out of the inside of the card slot 603, so that the support plate 601 loses its restriction. Then the second spring 602 restores its deformation and pushes the arc tooth plate 2 to move out of the inside of the slot 4 through the support plate 601. In this way, the arc tooth plate 2 can be directly popped out for easy disassembly.
