Description

A kind of fixation bracket for frame drum four-point suspension

Technical field

The utility model relates to musical instrument equipment technology field, specially a kind of fixed branch for frame drum four-point suspension Frame.

Background technique

Frame drum is essential percussion instrument in jazz, usually by a foot-operated pucking, army's drum, two with Upper eardrum, one or two hangs small cymbals and a part such as small cymbals of stepping on pedal forms.Currently, frame drum is often filled by trifilar suspension It sets and is fixed in drum, but the suspension arrangement is during installation usually using bolt fastening in the drum head pressing ring and drum chamber for compressing drum head On, in this way, thus inevitably needing to produce multiple mounting holes on drum chamber wall, therefore the necessarily tone color to drum itself, sound Matter impacts.Secondly the upper drum surface of frame drum needs repeatedly to replace, previous fixation support Design due to regular percussion It is relatively complicated, replacement trouble.

For example, application No. is 201520312779.0, a kind of utility model of frame drum four-point linkage of patent name Patent:

It is mutually fixed with wall card respectively by remaining four end that upper triangle hangs piece and lower triangle suspension piece, and wall card Eardrum is fixed in the drum chamber wall edge for being articulated in frame drum, is on the one hand to be fixed by wall card to eardrum, wall card quantity It is more, and wall card will also hang piece with upper and lower triangle and be attached, it is relatively complicated if being replaced to eardrum；On the other hand it is Wall card device is relatively fine, is operated for a long time, in fact it could happen that the hidden danger to fall off.

But the fixed bracket of existing frame drum has the following deficiencies:

(1) current frame drum suspension arrangement during installation usually using bolt fastening compress drum head drum head pressing ring and It in drum chamber, needs to produce multiple mounting holes on drum chamber wall, therefore necessarily tone color, the sound quality of drum itself is impacted；

(2) due to frame drum itself the characteristics of, often periodically will be adjusted fastening to drum surface, or carry out to upper eardrum Replacement, and structure is complicated for hang fixed support itself, the mode of replacement and fastening is relatively complicated, brings inconvenience.

Summary of the invention

In order to overcome the shortcomings of prior art, the utility model provides a kind of fixation for frame drum four-point suspension Bracket can effectively solve the problem of background technique proposes.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of fixation bracket for frame drum four-point suspension, including drum chamber and drum chamber wall, on the outer wall of the drum chamber wall Equipped with two groups of inner circle annular rings, it is provided with drum head above the drum chamber, lower drum head is provided with below the drum chamber, it is described Upper drum head and lower drum head are covered inner circle annular ring, and the upper equal outer circle annular ring and arc of the upper drum head and lower drum head rise Coil support is fixed, and the outer circle annular ring and arc piston ring bracket are on the fixed bracket of one side of something, the half of fixed branch Frame includes arc piston ring bracket, bolt, anti-billiards and outer circle annular ring, is fixedly welded with spiral shell below the arc piston ring bracket Bolt, the top of the arc piston ring bracket are equipped with outer circle annular ring and anti-billiards, the bolt on the fixed bracket of described two groups of one side of something It is threaded with U-shaped Double-ended nut, the fixed bracket of described two groups of one side of something and U-shaped Double-ended nut constitute fixed bracket.

Further, the fixed bracket of described two groups of one side of something is about U-shaped Double-ended nut central symmetry.

Further, internal screw thread built in the both ends of the U-shaped Double-ended nut.

Further, the anti-billiards is hemispherical, and material is soft environment-friendly rubber.

Further, the bolt thread on the fixed bracket of described two groups of one side of something is contrary.

Further, the fixed bracket is equipped with four groups altogether on drum chamber wall, and about frame drum central symmetry.

Further, the inner circle annular ring is total to be distributed with two groups about drum chamber central symmetry.

Compared with prior art, the utility model has the beneficial effects that

(1) the support bracket fastened fixed form of the utility model does not need to rouse wall fabrication and installation hole again, can guarantee frame drum Tone color and sound quality；

(2) design structure of the utility model is simple, and fixed form operation is easy, convenient for it is regular to frame drum into The operation of the fastening of row eardrum and eardrum replacement, when design, increase anti-billiards design, prevent frame drum from inadvertently falling off to frame drum The damage of itself and tone color, sound quality.
