Description

Drum structure

This creation is about a drum structure.

In a pedal module for a partial percussion instrument, at least one drum structure and one or more tapping portions are usually included, so at least one set of drum pedal structures is required to drive the tapping portion to perform a tapping action.

For example, US Pat. No. 6,110, 146, 475 and US Pat. No. No. 20070044 637 disclose a similar structure in which a spring is disposed between the coupling portion of the rotating shaft and the fixed link to strike the pedal to cause the drumstick to strike and release the pedal. The pedal and the drumstick can be automatically returned to their original positions.

However, the position of the spring of the above-mentioned patent is not appropriate, and the drumstick is subjected to a knocking action and is returned to the original position, and the problem of swinging back and forth due to the swinging inertia of the structure is caused by the swinging inertia for a long time, so the operation of the drumstick is unstable and comfortable. Accurately, there is a lack of improvement in the above-mentioned conventional drum pedal structure.

The main purpose of this creation is to provide a drum pedal structure, which can avoid the problem of swinging back and forth for a long time after the structure is actuated, and the movement is more stable, comfortable, accurate, and convenient to disassemble, replace, and store.

In order to achieve the above object, the present invention provides a drum structure including a base, a rotating shaft, a link assembly and a pedal. The base comprises a bottom plate and a first column standing on the bottom plate, and the first column is radially provided with a joint portion. The rotating shaft is disposed on the first column and rotatable about an axis of the rotating shaft. The connecting rod assembly has a first end and a second end, a rod connected between the first and second ends, and an elastic member, the first end being pivotally connected to one end of the rotating shaft, the rod The elastic member is sleeved on the rod and located between the second end and the joint portion. The pedal is swingably disposed at one end of the bottom plate, and the other end thereof is coupled to the rotating shaft. The pedal swings to rotate the rotating shaft about the axis and interlock the swinging of the connecting rod assembly.

In order to achieve the above object, the present invention further provides a drum structure including a base, a rotating shaft, a link assembly and a pedal. The base comprises a bottom plate and a first column standing on the bottom plate, and the first column is radially provided with a joint portion.
