Press-plate-type top support for bass drum

Abstract

The invention provides a press-plate-type top support for a bass drum. In the invention, a connecting insertion tube with a top tooth surface is inserted into the top of a steel tube of the support; two sides of the steel tube are respectively equipped with a mechanism for fixing a drumhead ball bar; the mechanism for fixing the drumhead ball bar at one side comprises a fixing seat fixed on the connecting insertion tube, a lower press plate is arranged at the lower part of the fixing seat and is connected with the steel tube through a knurling pin, and the fixing seat and the lower press plate tightly clamp the drumhead ball bar through a bolt and a locking knob; and for the mechanism for fixing the drumhead ball bar at the other side, a tooth surface is arranged on the bottom surface at one side of an upper movable press plate seat and corresponds to the top tooth surface of the connecting insertion tube, the upper movable press plate seat is fixed on the connecting insertion tube through a locking bolt, the middle part of the upper movable press plate seat is equipped with an insertion hole and is connected with the one side of the lower press plate through a knurling pin inserted into the insertion hole, and the other side of the upper movable press plate seat and the other side of the lower press plate tightly clamp the drumhead ball bar through bolts and locking knobs. The press-plate-type top support has the beneficial effects that the clamping mechanisms of the top support for the bass drum can adjust the clamping direction of drumheads and generate large and steady clamping forces, thus reducing the adjustment time during a performance process; and the appearance is unique and beautiful.

Description

technical field [0001] The invention relates to a percussion instrument, in particular to a pressing plate type big drum top support for a drum. Background technique [0002] A drum kit is a very important percussion instrument in a jazz band. It usually consists of a bass drum and multiple ear drums hung on both sides of the bass drum. A single drummer can manipulate multiple percussion instruments at the same time. Among them, the fixation of the ear drum is the key. At present, the pressing methods of the big drum top support abroad include: screw positive top pressing, inclined block pressing, eccentric pressing and other different structures. However, these clamping mechanisms have low pressure and poor stability, and the adjustment direction of both the bass drum and the ear drum is limited, and the clamped steel pipe is easily deformed, which directly affects the clamping, adjustment, and playing effects of the ear drum. Contents of the invention [0003] Aiming a...
