Examples

As shown in fig. 1 to 3, a rattle drum capable of adjusting sound comprises a drum handle 1, a drum rack 7 is fixed to the upper end of the drum handle 1, drum surfaces 2 are arranged at the open ends of the two sides of the drum rack 7, two drum surfaces 2 are fixedly connected to the center of the opposite side through a rotating shaft 9, a convex ring 8 is fixed to the side face of the opposite side of the drum surface 2, the convex ring 8 is fixedly connected to the inside of the drum rack 7 in a rotating mode in a fixed shaft mode, a plurality of music modules 6 are fixed to the outer side face of the drum surface 2, guide sleeves 3 are fixed to the side walls of the two sides of the drum rack 7, a pull rod 18 is slidably connected to the inside of the guide sleeves 3, one end, pointing to the outside of the drum rack 7, of the pull rod 18 is connected with a drumstick 5 through a pull rope 4, and.

In this embodiment, the music modules 6 are arranged at equal intervals along the circumferential direction of the drumhead, the drumstick 5 can be in abutting contact with the music modules 6, and each music module 6 can issue different music sounds.

In this embodiment, a guide plate 11 is disposed inside the drum rack 7, and two ends of the guide plate 11 are fixedly connected to the inner wall of the drum rack 7 through a bracket 12.

In this embodiment, a sliding rod 13 penetrates through the guide plate 11, the sliding rod 13 can slide on the guide plate 11, the upper end of the sliding rod 13 is connected with the inner wall of the drum rack 7 through a spring 14, and a pressing plate 15 is fixed at the lower end of the sliding rod 13.

In this embodiment, two ends of the pressing plate 15 are hinged to corresponding pull rods 18 through connecting rods 17, a rack 16 is fixed on the bottom surface of the pressing plate 15, the rack 16 is meshed with an outer ring of the ratchet 10 fixed on the rotating shaft 9, the outer ring of the ratchet 10 rotates counterclockwise to drive the inner ring to rotate through a pawl, and the outer ring of the ratchet 10 rotates clockwise to drive the inner ring to rotate through the pawl.

In this embodiment, the sliding rod 13 and the drum handle 1 share a central axis, the pull rod 18 is perpendicular to the sliding rod 13, and the rack 16 and the sliding rod 13 are parallel to each other.

The utility model discloses a principle and advantage: when the sound-adjustable rattle drum is used, the drum handle 1 is rotated to enable the drum handle 1 to drive the drum frame 7 to synchronously rotate, the drum frame 7 drives the corresponding drumstick 5 to rotate through the pull rope 4, the drumstick 5 is thrown up and strikes the music module 6 at the corresponding position on the drum surface 2, the music module 6 gives out music, the drumstick 5 is under the action of centrifugal force in the throwing process and exerts a pulling force pointing to the outer side of the drum frame 7 on the pull rod 18 through the centrifugal force, the pull rod 18 moves outwards under the guiding action of the guide sleeve 3, the pull rod 18 moves outwards to exert a downward pulling force on the pressure plate 15 through the connecting rod 17, the pressure plate 15 synchronously moves the rack 16 and the slide rod 13 downwards, the downwards moving rack 16 drives the outer ring of the ratchet 10 to clockwise rotate, the outer ring of the ratchet 10 cannot drive the inner ring to rotate through the pawl in the clockwise rotating process, so as to be incapable of driving the rotating shaft 9 to rotate, and further keep the drumstick 5 to keep the drumhead 2 immovable when hitting the drumhead 2, the downward movement of the slide rod 13 stretches the spring 14 to obtain an upward restoring force, when the drumstick 5 stops after hitting the drumhead 2, the drumstick 5 is not subjected to centrifugal force, so that the slide rod 13 moves upward under the upward restoring force of the spring 14 and synchronously drives the press plate 15 to move upward, the upward moving synchronous belt of the press plate 15 moves the rack 16 upward, so that the rack 16 drives the outer ring of the ratchet 10 to rotate counterclockwise, the outer ring of the ratchet 10 can drive the inner ring to rotate counterclockwise through the pawl in the counterclockwise rotating process, so that the rotating shaft 9 is driven to rotate counterclockwise through the inner ring of the ratchet 10, and further drive the drumhead 2 to rotate counterclockwise, so that the position of the music module 6 on the drumhead 2 is changed to emit different music sounds at the next hitting, the corresponding pull rod 18 is driven to move, so that the drumstick 5 is used for driving the drumhead 2 when throwing next time, the whole process realizes that the drumhead can emit different music sounds when the drumstick 1 is rotated, the drumhead 2 is automatically rotated, and the interestingness of the rattling drum is improved.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
