Description

Technical Field

[0001] This utility model relates to the field of piano pedal technology, specifically an adjustable piano pedal device. Background Technology

[0002] The piano pedals are a component of the piano. Upright pianos generally have three pedals: the middle pedal, the left pedal, and the right pedal. The middle pedal is called the soft pedal, which weakens the sound. It is often used when practicing at home to avoid disturbing the neighbors. The left pedal is called the soft pedal, which can change the tone. The right pedal is called the sustain pedal, which can prolong the musical tone and enhance the sound effect.

[0003] In the traditional piano design, the pedals are usually fixed. This design has obvious drawbacks when children are learning piano. Because children are still growing and their legs are not long enough, they often have difficulty reaching the pedals. This adds many obstacles to their piano learning and makes it difficult for them to complete some playing operations that require pedal coordination, thus causing delays and difficulties in their learning process. Therefore, we provide an adjustable piano pedal device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an adjustable piano pedal device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable piano pedal device, comprising a piano body, a lifting housing at the bottom of the piano body, and an adjustment component on the outside of the lifting housing. The adjustment component includes a rotating rod, a rack, a sliding groove, and a support rod. The rotating rod is located inside the piano body and is rotatably connected to the inner wall of the piano body. The rack is fixedly connected to the outer surface of the lifting housing. The sliding groove is opened on the outer surface of the piano body. The support rod is located inside the piano body and is fixedly connected to the inner wall of the piano body.

[0006] Preferably, a knob is fixedly connected to the other end of the rotating rod, and a gear is fixedly connected to the outer surface of the rotating rod, the gear meshing with a rack.

[0007] Preferably, a sliding block is slidably connected to the inner wall of the sliding groove, and the side of the sliding block near the lifting box is fixedly connected to the outer surface of the lifting box.

[0008] Preferably, a ratchet is fixedly connected to the outer surface of the rotating rod, and a locking plate is rotatably connected to the outer surface of the support rod, the locking plate engaging with the ratchet.

[0009] Preferably, a spring is fixedly connected to the bottom surface of the card plate, and the other end of the spring is fixedly connected to the inner wall of the piano body. An L-shaped plate is slidably connected to the inner wall of the piano body.

[0010] Preferably, the interior of the lifting box is provided with a pedal body, and the bottom surface of the piano body is fixedly connected to two support legs.

[0011] Beneficial effects:

[0012] Compared with existing technologies, this adjustable piano pedal device has the following advantages:

[0013] I. This utility model, through the cooperation between the piano body, the lifting box, and the adjustment components, allows the rotation of the knob to drive the gears, and the meshing between the gears and the rack can achieve the effect of adjusting the height of the pedal body. This is convenient and quick, making it easy for children of different heights to use the pedal body, enabling children to complete their piano learning smoothly.

[0014] Second, this utility model utilizes the cooperation between the ratchet and the locking plate. After the pedal body is adjusted to a suitable height, the locking plate will engage with the tooth groove of the ratchet, thereby limiting the rotation rod and preventing it from reversing when the pedal body is stepped on, thus affecting the normal use of the device.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] See Figures 1-4An adjustable piano pedal device includes a piano body 1, a lifting housing 2 at the bottom of the piano body 1, and an adjustment component 3 on the outside of the lifting housing 2. The adjustment component 3 includes a rotating rod 301, a rack 303, a sliding groove 305, and a support rod 309. The rotating rod 301 is located inside the piano body 1 and is rotatably connected to the inner wall of the piano body 1. The rotating rod 301 can rotate on the inner wall of the piano body 1 to facilitate subsequent adjustment of the height of the lifting housing 2.

[0022] The rack 303 is fixedly connected to the outer surface of the lifting box 2. A knob 304 is fixedly connected to the other end of the rotating rod 301. A gear 302 is fixedly connected to the outer surface of the rotating rod 301. The gear 302 meshes with the rack 303. Through the meshing between the gear 302 and the rack 303, the rack 303 can be driven to move upward when the gear 302 rotates, thereby realizing the function of adjusting the height of the lifting box 2.

[0023] The sliding groove 305 is formed on the outer surface of the piano body 1. The inner wall of the sliding groove 305 is slidably connected to a sliding block 306. The sliding block 306 enables the lifting box 2 to rise more smoothly and prevents the lifting box 2 from shaking.

[0024] The sliding block 306 is fixedly connected to the outer surface of the lifting box 2 on one side. The support rod 309 is located inside the piano body 1 and fixedly connected to the inner wall of the piano body 1. A ratchet 307 is fixedly connected to the outer surface of the rotating rod 301. A locking plate 308 is rotatably connected to the outer surface of the support rod 309. The locking plate 308 is engaged with the ratchet 307. When the ratchet 307 rotates in the forward direction, the locking plate 308 will move downward to compress the spring 310 so that the ratchet 307 can rotate normally. When the ratchet 307 stops rotating, the locking plate 308 will be locked in the tooth groove of the ratchet 307, thereby preventing the ratchet 307 from reversing.

[0025] A spring 310 is fixedly connected to the bottom surface of the plate 308. The other end of the spring 310 is fixedly connected to the inner wall of the piano body 1. An L-shaped plate 311 is slidably connected to the inner wall of the piano body 1. By pulling the L-shaped plate 311, the plate 308 can be moved downward, thereby releasing the limit on the ratchet 307 and facilitating the downward movement of the lifting box 2.

[0026] The lifting box 2 is equipped with a pedal body 4 inside. The bottom surface of the piano body 1 is fixedly connected to two support legs 5. The support legs 5 can support the piano body 1, so that the piano body 1 can be used stably.

[0027] Working principle: When adjusting the height of the pedal body 4, first turn the knob 304 to drive the rotating rod 301 to rotate. When the rotating rod 301 rotates, it will drive the gear 302 to rotate. By utilizing the meshing between the gear 302 and the rack 303, the rack 303 moves upward, thereby achieving the effect of adjusting the height of the pedal body 4. After the height adjustment is completed, the locking plate 308 will engage in the tooth groove of the ratchet 307 to limit the gear 302, thereby preventing the gear 302 from reversing when the pedal body 4 is stepped on, which would affect the normal use of the device. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
