Description
Technical Field
The utility model relates to the technical field of piano accessories, in particular to a pedal lever weight adjusting device of an upright piano.
Background
The weight of the existing pedal lever of the piano is different, and the pedal force of players with different ages is different, so that the weight of the pedal lever cannot be adjusted well during playing, the player can feel uncomfortable, and thus, good physical and psychological enjoyment cannot be obtained.
Disclosure of Invention
Aiming at the technical problems in the background art, the utility model provides a pedal lever weight adjusting device of an upright piano.
In order to achieve the above object, the present utility model provides a pedal lever weight adjusting device of an upright piano, which is installed between a pedal lever bracket and pedals of the upright piano, comprising a base, an adjusting spring, a spring bushing and a spring pre-pressing member;
the base is fixed on the piano bottom plate through screws;
the adjusting spring is vertically fixed on the base;
the spring bushing is fixed at the lower part of the lever and corresponds to the position right above the adjusting spring;
the spring pre-pressing component comprises an adjusting screw, a fastening nut and a pressing plate;
the adjusting screw is in threaded connection with the lever and penetrates through the lever into the spring bushing;
the pressing plate is arranged at the bottom of the adjusting screw, is positioned in the spring bushing and is used for pressing the adjusting spring;
the fastening nut is tightly sleeved on the outer wall of the adjusting screw, and the position of the adjusting screw is fixed after the adjusting spring is pressed to a proper position.
Compared with the prior art, the utility model has the advantages that: the pedal lever weight adjusting device of the vertical piano designed by the utility model is characterized in that the compression amount of an adjusting spring is increased by rotating an adjusting screw downwards, and the corresponding elastic force is increased; otherwise, the adjusting screw is rotated upwards, the compression amount of the adjusting spring is reduced, and the corresponding elastic force is reduced. After the pedal force is properly adjusted, the fastening nut is fixed. The spring force acting on the lever determines the weight of the lever, so that the pedal lever weight is adjusted. The utility model has novel design and ingenious structure, solves the problems that the height of the existing pedal is unchanged and the pedal force can be adjusted at any time, meets the requirements of piano players in different ages, and improves the overall comfort.

Wherein, 1-lever axle bracket, 2-piano bottom plate, 3-adjusting screw, 4-fastening nut, 5-clamp plate, 6-spring bush, 7-adjusting spring, 8-base, 9-pedal lever, 10-pedal, 11-wood ejector pin.
Detailed Description
In the following, in order to facilitate the understanding of the technical solutions of the present utility model by a person skilled in the art, reference will be made to the accompanying drawings for further description. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the utility model. It may be evident, however, that one or more embodiments may be practiced without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
As shown in fig. 1, which is a schematic view of the overall structure of the pedal lever weight adjusting device of the upright piano of the present utility model, the adjusting device is installed between the pedal lever spindle bracket 1 and the pedal 10 of the upright piano, and the wood jack 11 is used for supporting the pedal lever. The adjusting device provided by the embodiment comprises a base 8, an adjusting spring 7, a spring bushing 6 and a spring pre-pressing part. The base 8 is fixed on the piano bottom plate 2 through the screw, adjusting spring 7 is vertical to be fixed on the base 8, spring bush 6 is fixed in pedal lever 9 lower part, correspond directly over adjusting spring 7, spring pre-compaction part includes adjusting screw 3, fastening nut 4 and clamp plate 5, adjusting screw 3 and pedal lever 9 threaded connection, and run through pedal lever 9 to in the spring bush 6, the bottom of adjusting screw 3 is located to clamp plate 5, and be located spring bush 6, be used for supporting pressure adjusting spring 7, fastening nut 4 closely overlaps and establish at adjusting screw 3 outer wall, the position of fixed adjusting screw 3 after adjusting spring 7 is supported and pressed to suitable position.
The working principle of the device is as follows:
the pedal lever weight adjusting device of the upright piano provided by the embodiment is characterized in that the compression amount of the adjusting spring 7 is increased by rotating the adjusting screw 3 downwards, and the corresponding elastic force is increased; conversely, the adjusting screw 3 is rotated upwards, the compression amount of the spring is reduced, and the corresponding elastic force is reduced. After the pedal force is properly adjusted, the fastening nut 4 is fixed. The spring force acting on the lever 9 determines the lever weight, which plays a role in adjusting the pedal lever weight. The utility model has novel design and ingenious structure, solves the problems that the height of the existing pedal is unchanged and the pedal force can be adjusted at any time, meets the requirements of piano players in different ages, and improves the overall comfort.
The above examples are only illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the scope of protection defined by the claims of the present utility model without departing from the spirit of the present utility model.
