Description

Technical Field

[0001] This utility model belongs to the field of mechanical metronomes, specifically a beat adjustment mechanism on a mechanical metronome. Background Technology

[0002] Existing mechanical metronomes are typically available in two, four, or six beats, which may not meet the requirements of complex beat variations. Furthermore, the number of teeth in the bell control gear set is relatively limited, failing to provide a sufficiently wide adjustment range, thus affecting the overall performance and applicability of the metronome. Utility Model Content

[0003] The purpose of this invention is to address the above problems by providing a beat adjustment mechanism for a mechanical metronome, which can increase the number of selectable beats and improve applicability.

[0004] To achieve the above objectives, the present invention employs a beat adjustment mechanism for a mechanical metronome. This mechanism includes a driven gear shaft with a concentric driven gear. A ringing control gear set and a ratchet set are spaced apart along the axial direction of the driven gear shaft. The ratchet set includes two ratchets arranged axially along the driven gear shaft, each ratchet having twelve teeth. The ringing control gear set includes five adjusting gears arranged axially along the driven gear shaft, with the adjusting gears having three, four, six, eight, and twelve teeth respectively. The adjusting gear with three teeth is located on one side of the ratchet set. By increasing and adjusting the number and teeth of the adjusting gears, the number of beats can be increased.

[0005] Furthermore, the ratchet is a straight-tooth ratchet to simplify the structure and reduce equipment costs while ensuring cycle stability and accuracy.

[0006] The beneficial effects of this utility model are as follows: Compared with the traditional mechanical metronome, this utility model increases the number of adjusting gears used in the mechanical metronome, and at the same time adjusts the number of teeth on different adjusting gears, the number of teeth on the ratchet, and the arrangement relationship of the adjusting gears, so that the number of beats that can be selected by the metronome increases and its applicability is significantly improved.

[0009] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0010] Example 1, such as Figure 1 As shown, the specific structure of this embodiment is as follows: It includes a driven gear shaft 1, on which a driven gear 2 is arranged concentrically. The driven gear 2 meshes with the driving gear in the mechanical metronome, which is driven by a spring or similar mechanism used in existing mechanical metronomes. A ringing control gear set and a ratchet set are spaced apart along the axial direction of the driven gear shaft 1. The ratchet set includes two ratchet wheels 3, which are spur-tooth ratchets. The two ratchet wheels 3 are arranged along the axial direction of the driven gear shaft 1, and the number of teeth on each ratchet wheel 3 is set to twelve. The ratchet wheels 3 are adapted to the stop ring in existing mechanical metronomes. The ringing control gear set includes five adjusting gears 4, which are arranged along the axial direction of the driven gear shaft 1. The number of teeth on each adjusting gear 4 is set sequentially to three, four, six, eight, and twelve, with the adjusting gear 4 with three teeth located on one side of the ratchet set. The adjusting gears 4 and ratchet wheels 3 are preferably made of metal.

[0011] When using it, the beat can be adjusted as needed via the lever on the mechanical beater, such as two, four, six, or eight beats. This helps the user better control the rhythm.

[0012] The present invention has been described in detail above with reference to the embodiments. However, the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of implementation of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the protection scope of the present invention.
