Description

Technical Field

[0001] The invention particularly relates to a piano pedal with a height adjustment function. Background Art

[0002] An upright piano generally has three piano pedals, namely: the middle piano pedal, the left piano pedal and the right piano pedal. The middle pedal is called the soft piano pedal, which has the function of weakening the sound, the left piano pedal is called the soft piano pedal, which can change the timbre, and the right piano pedal is called the sustain piano pedal, which can prolong the sound and enhance the sound effect.

[0003] Existing patents such as patent number CN114120936A disclose a piano pedal, wherein a foot piano pedal is arranged parallel to the top of the base plate, and a limiting mechanism is movably connected to the support column. The limiting mechanism is inserted into limiting grooves at different positions to adjust the height of the foot piano pedal. After the foot piano pedal is adjusted to a position that makes the foot comfortable to step on, the limiting mechanism limits the foot piano pedal, and the height of the piano pedal can be conveniently adjusted according to the height and leg length of the child.

[0004] The above patent can adjust the height of the piano pedals, but in actual use, it is necessary to add an additional mechanism to the position of the piano pedals, which affects the normal use of the piano pedals by people of normal height. In addition, when adjusting the height of the piano pedals, additional auxiliary equipment needs to be installed for adjustment, and the adjustment equipment needs to be carried with you all the time. The height of the piano pedals cannot be adjusted anytime and anywhere, which has great limitations. For this reason, we propose a piano pedal with a height adjustment function. Summary of the invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-8 , the present invention provides a technical solution: a piano pedal with a height adjustment function, including:

[0035] A box body 1, on one side of which a piano pedal 2 is rotatably installed, and an installation groove is provided on the piano pedal 2;

[0036] A fixed cylinder 204 is arranged inside the installation groove, and one end of the fixed cylinder 204 is provided with a connecting shaft 203 that is rotationally matched with the installation groove, and one end of the connecting shaft 203 penetrates through one side wall of the piano pedal 2 and is fixedly connected to a first worm gear 205;

[0037] A first worm 202 is rotatably arranged on one side wall of the piano pedal 2 and is matched with the first worm gear 205;

[0038] A telescopic rod 207 is arranged at one end of the fixed cylinder 204, and one end of the telescopic rod 207 is connected to an adjusting plate 208 through a rotational adjustment assembly;

[0039] A wind power assembly is arranged inside the box body 1 corresponding to the piano pedal 2 to clean the surface of the piano pedal 2;

[0040] When in use, when it is necessary to adjust the height of the piano pedal 2, the cover plate 201 can be pulled out from the rectangular groove of the piano pedal 2, so that the fixed cylinder 204 is exposed. Then, by rotating the first worm 202, the first worm gear 205 can be driven to rotate, and the connecting shaft 203 and the fixed cylinder 204 can be synchronously driven to rotate upward from the inner side of the rectangular groove of the piano pedal 2, thereby synchronously driving the adjusting plate 208 to rise from the rectangular groove of the piano pedal 2. After adjusting the rising angle of the fixed cylinder 204, then by rotating the control ring 206, through the threaded cooperation between the control ring 206 and the telescopic rod 207, the telescopic rod 207 can be driven to slide outward along the inside of the fixed cylinder 204, thereby driving the adjusting plate 208 to rise, achieving the purpose of adjusting the height of the adjusting plate 208.

[0041] A control ring 206 is rotatably sleeved at one end of the outer surface of the fixed cylinder 204, and the control ring 206 is matched with the telescopic rod 207 through a threaded portion;

[0042] Anti-slip lines are axially arranged on the outer surface of the control ring 206;

[0043] The rotation adjustment assembly includes a second worm 209 and a second worm gear 210. An adjustment shaft matched with the adjustment plate 208 is arranged inside one end of the telescopic rod 207. A second worm gear 210 is fixed at one end of the adjustment shaft. The second worm 209 is rotatably installed on the side plate at one end of the telescopic rod 207, and the second worm 209 is engaged with the second worm gear 210;

[0044] The adjustment plate 208 is rectangular.

[0045] After adjusting to a suitable height, the second worm 209 can be rotated to drive the second worm gear 210 to rotate, thereby driving the adjustment plate 208 to rotate at the front end of the telescopic rod 207, adjusting the orientation angle of the adjustment plate 208, so that the adjustment plate 208 can fit more closely with the bottom of the user's foot, thereby being beneficial to improving the comfort and experience during use; by adjusting the adjustment plate 208 to a suitable height, when the user needs to step on the piano pedal 2, the piano pedal 2 can be directly stepped on the adjustment plate 208, and the fixed cylinder 204 and the connecting shaft 203 can be driven to move downward through the telescopic rod 207, so that the piano pedal 2 can complete the stepping action, meeting the use needs of people with different heights.

[0046] The wind power assembly includes a fan blade 101, a transmission gear 102, a slide rod 103, a push rod 104, a transmission rack 105 and a connecting rod 106. A support plate is fixed to the side wall of the box body 1. The slide rod 103 is slidably installed inside the support plate, and a return spring is sleeved on the outer surface of the slide rod 103. The push rod 104 is fixed to the top end of the slide rod 103. The transmission rack 105 is provided on the lower surface of the push rod 104. A rotating shaft is provided inside the box body 1. One end of the rotating shaft is fixed with the fan blade 101. A transmission gear 102 that cooperates with the transmission rack 105 is provided on the outer surface of the rotating shaft. The connecting rod 106 is fixed to one side wall of the slide rod 103, and one end of the connecting rod 106 corresponds to the piano pedal 2;

[0047] The connecting rod 106 is in a "door" shape;

[0048] A plurality of transmission racks 105 are arranged along the long side of the push rod 104.

[0049] During the process of stepping on the piano pedal 2, the piano pedal 2 moves downward, so that it can synchronously press the bottom connecting rod 106 to move downward, and synchronously drive the two groups of slide rods 103 on both sides to move downward through the connecting rod 106. During this process, the push rod 104 and the transmission rack 105 are synchronously driven to move downward, so as to drive the transmission gear 102 and the fan blade 101 to rotate to generate suction or blowing force through the transmission rack 105, and the impurities such as garbage carried by the bottom of the shoe and the dust that may stay on the piano pedal 2 are cleaned through the rectangular through groove structure opened on the front side of the box body 1, maintaining the cleanliness and beauty of the piano pedal 2, and being beneficial to reducing the burden of manual cleaning.

[0050] Preferably, a cover plate 201 is provided at the upper end inside the installation groove.

[0051] Preferably, the number of the first worm gears 202 is the same as the number of the piano pedals 2.

[0052] When not in use, the adjusting plate 208 and the fixing cylinder 204 are retracted into the rectangular groove on the top of the piano pedal 2, and the cover plate 201 is slid into the T-shaped sliding grooves on both sides of the rectangular groove of the piano pedal 2 to close the rectangular groove on the top of the piano pedal 2, facilitating the normal use of the piano pedal 2.
