Description

Technical Field

[0001] This utility model relates to the field of piano key press technology, and in particular to a piano key press with a stable structure. Background Technology

[0002] The key stop is a structure in pianos that presses down on the keys to prevent them from rising excessively during playing. It also helps adjust the sound of the piano and is an indispensable part of the piano.

[0003] Because the keystop is relatively long, made of wood, and fixed only at both ends, it is prone to deformation. Furthermore, the player's key-pressing habits greatly influence the keystop. If the player applies excessive or uneven pressure while playing, certain keys will be subjected to excessive pressure, causing the keystop to experience pressure exceeding its tolerance and leading to deformation. Given the problem of deformation in existing keystops due to their length and the way they are fixed at both ends, this invention aims to provide a stable structure that provides auxiliary support in the middle of the keystop's span or in areas requiring reinforcement. This structural design fully considers the interior of the piano, especially the space below the keys and between the keystop and the piano stand. Its installation position is located below the parallel keys, without interfering with the normal movement of the keys. Therefore, we propose a structurally stable piano keystop.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a structurally stable piano key stop, including a piano base 1 and a key stop 2. The key stop 2 is located on the upper surface of the piano base 1. A horizontal plate 3 for structural connection is provided on the upper surface of the piano base 1. Two mirror-shaped fixing plates 4 for fixing the key stop 2 are fixedly connected to the upper surface of the horizontal plate 3. The left fixing plate 4 contacts the right surface of the key stop 2. When fixing the key stop 2, the key stop 2 is first placed in a suitable position, and then the horizontal plate 3 and the two fixing plates 4 are placed on the right side of the key stop 2. On the side surface, a pressure plate 5 for pressing the key block 2 is fixedly connected to the left side surface of the left fixed plate 4. A triangular cavity 6 is formed between the horizontal plate 3 and the two fixed plates 4. A groove 7 for subsequent structural installation is opened on the left side surface of the left fixed plate 4. A push plate 8 is set inside the groove 7. A stabilizing plate 9 for reducing the deformation of the key block 2 is set inside the groove 7. A telescopic groove 10 is opened on the right side surface of the horizontal plate 3. An adjustment component is set inside the telescopic groove 10, which can effectively share the force borne by the key block 2, prevent it from moving, and increase stability.

[0025] The adjustment assembly includes a displacement rod 11 for structural installation. The displacement rod 11 is slidably connected inside the telescopic groove 10. The right side surface of the displacement rod 11 extends out of the telescopic groove 10. A first fixing bolt 12 for fixing the displacement rod 11 is provided on the upper side surface. The displacement rod 11 is fixedly connected to the instrument stand 1 by means of the first fixing bolt 12. A through groove 13 extending from the rear side surface of the displacement rod 11 for structural passage is formed on the front side surface. A threaded hole 14 extending from the rear side surface of the telescopic groove 10 is formed on the rear inner wall of the telescopic groove 10. A sliding groove 15 extending into the telescopic groove 10 is formed on the front side surface of the horizontal plate 3. A second fixing bolt 16 is provided on the front side for fixing the horizontal plate 3 and the displacement rod 11. The rear end of the second fixing bolt 16 extends out of the rear surface of the horizontal plate 3. The second fixing bolt 16 is threadedly connected to the threaded hole 14. By rotating the second fixing bolt 16, the second fixing bolt 16 will be displaced when rotating. After the second fixing bolt 16 is displaced, it will disengage from the threaded hole 14, thus unlocking the displacement rod 11 from the horizontal plate 3. At this time, move the key stop 2, the horizontal plate 3 and the fixing plate 4. After adjusting the position, rotate the second fixing bolt 16 again so that the second fixing bolt 16 re-enters the interior of the threaded hole 14 to complete the fixing of the horizontal plate 3 and the displacement rod 11.

[0026] The second fixing bolt 16 is movably connected to the through groove 13. A third fixing bolt 17 is provided on the pressure plate 5 to fix the pressure plate 5 and the key stop 2. Then, the horizontal plate 3 is fixed by the first fixing bolt 12. After fixing, the pressure plate 5 and the key stop 2 are fixed by the third fixing bolt 17. The pressure plate 5 is fixedly connected to the key stop 2 by the third fixing bolt 17. A fourth fixing bolt 18 is provided on the right side surface of the stabilizing plate 9 to fix the stabilizing plate 9 and the key stop 2. The stabilizing plate 9 is fixedly connected to the key stop 2 by the fourth fixing bolt 18. The triangular cavity 6 is provided with a mechanism for adjusting the position of the push plate 8. Adjusting bolt 19, with its left end threaded through the left surface of the left fixing plate 4, is rotatably connected to push plate 8. Stable plate 9 is inserted into the groove 7, and the stable plate 9 is fixed to key stop 2 by means of fourth fixing bolt 18. At this time, adjusting bolt 19 is rotated, and it will move when it rotates. Push plate 8 is pushed to move by means of the movement of adjusting bolt 19. After the push plate 8 moves, it is in close contact with stable plate 9. Push plate 8 is slidably connected to the upper and lower inner walls of groove 7. With the help of the displacement rod 11 and the cross plate 3 separate design, it is more convenient to adjust key stop 2.

[0027] Working principle: When fixing the key stop 2, first place the key stop 2 in a suitable position, then place the horizontal plate 3 and two fixing plates 4 on the right side surface of the key stop 2, ensuring that the left fixing plate 4 is in close contact with the key stop 2. Then, fix the horizontal plate 3 with the first fixing bolt 12. After fixing, use the third fixing bolt 17 to fix the pressure plate 5 to the key stop 2. Then, insert the stabilizing plate 9 into the groove 7 and fix the stabilizing plate 9 to the key stop 2 with the fourth fixing bolt 18. At this time, rotate the adjusting bolt 19. When the adjusting bolt 19 rotates, it will move... The push plate 8 is moved by the movement of the adjusting bolt 19. After the push plate 8 moves, it is in close contact with the stabilizing plate 9. When it is necessary to adjust the left and right position of the key stop 2, the second fixing bolt 16 can be rotated. When the second fixing bolt 16 rotates, it will be displaced. After the second fixing bolt 16 is displaced, it will disengage from the threaded hole 14, thus unlocking the displacement rod 11 from the horizontal plate 3. At this time, the key stop 2, the horizontal plate 3 and the fixing plate 4 are moved. After the position is adjusted, the second fixing bolt 16 is rotated again, so that the second fixing bolt 16 re-enters the interior of the threaded hole 14 to complete the fixation of the horizontal plate 3 and the displacement rod 11.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
