Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a multifunctional butterfly twister. Background Art

[0002] An acoustic drum set, also known as a wood-chamber drum set, consists of a kick-operated bass drum, toms, snare drum, cymbals, and hi-hats. Its advantages are rich, realistic sound, and volume control, which is entirely controlled by the drummer and reflects the player's skill and rhythm. Electronic drums are signal processors that require a sound source and output device.

[0003] Currently, the bolts used to lock the drumheads of acoustic and electronic drums are the industry-standard square-head bolts. Manufacturers generally provide a wrench specifically for locking these square-head bolts, allowing customers to adjust the tension of the drumheads. At the same time, the drum plate is usually locked to the stand. To facilitate disassembly, manufacturers generally design the nuts that lock the stand into butterfly knobs. This allows users to tighten and remove the drumheads by hand without the need for special tools. However, the butterfly knob only has the ability to lock the nut and cannot adjust the square-head bolt as needed to achieve a dual-purpose effect. To this end, we propose a multifunctional butterfly knob. Utility Model Content

[0004] The purpose of the utility model is to provide a multifunctional butterfly twist with the advantage of dual use, which solves the problem that the butterfly twist only has the ability to lock the nut and cannot adjust the square head bolt as needed to achieve the dual use effect.

[0006] Preferably, the diameter of the internal threaded hole is smaller than the inner size of the square positioning hole.

[0007] Preferably, a hanging ring is provided on the right side of the butterfly twist body, and a carrying strap is provided on the inner side of the hanging ring.

[0008] Preferably, a movable groove is provided at the top and bottom of the right end of the butterfly twist body, a magnet is embedded in the inner cavity of the movable groove on the side close to the internal threaded hole, an extension plate is provided on the inner side of the movable groove, an iron sheet is fixedly connected to the side of the extension plate close to the magnet, and a connecting block is fixedly connected to the side of the extension plate away from the iron sheet.

[0009] Preferably, the movable slot is provided with limiting sliding grooves on both sides, and the extension plate is fixedly connected to limiting sliding blocks sliding in the limiting sliding grooves on both sides near one end of the iron sheet.

[0010] Preferably, the outer side of the butterfly twist body is coated with a first protective layer, and the outer side of the first protective layer is coated with a second protective layer.

[0011] Preferably, the material of the first protective layer is a fluorocarbon anti-corrosion coating layer, and the material of the second protective layer is an ultra-high molecular weight polyethylene coating.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model can cooperate with the square positioning head of the square head bolt body through the setting of the square positioning hole. When the butterfly twist body is rotated, the square head bolt body can be driven to rotate, thereby realizing the ability to adjust the drum surface tension. The setting of the internal threaded hole can enable the connecting screw on the lock frame to pass through the square positioning hole and be threadedly connected with the butterfly twist body, so that the butterfly twist has the ability to lock the nut, achieving a dual-purpose effect.

[0014] 2. When the butterfly twist body needs to be rotated to drive the square head bolt body for rotation adjustment, the utility model drives the expansion plate to move outward in the movable groove through the connecting block, and breaks the adsorption force of the magnet on the iron sheet, and with the assistance of the limiting slider and the limiting slide groove, the stability of the outward movement of the expansion plate is guaranteed. After the expansion plate is unfolded, the length of the right end of the butterfly twist body is expanded. When the user rotates the butterfly twist body, it can effectively reduce the power consumption of the hand, and is conducive to the tightening operation of the butterfly twist body and the connecting screw, which is convenient for the user to use.
