Abstract

The utility model relates to a portable drum, comprising drum leather, a drum ring, and a metal pressing ring, and the drum leather is wound on the metal pressing ring and press-mounted on the drum ring. The innovative points are that firstly, a drum leather supporting ring is mounted in the drum leather which is arranged above the metal pressing ring, a top-loading axle sleeve is fixedly mounted at an axial center portion of the drum leather supporting ring, secondly, a supporting ring holder is mounted in parallel below the drum ring through adjusting bolts which are evenly distributed and mounted on the periphery of the drum ring, a screw axle sleeve is fixedly mounted at the axial center portion of the supporting ring holder, thirdly, the screw axle sleeve of the supporting ring holder and the top-loading axle sleeve of the drum leather supporting ring are arranged on the same axle and meshed, a screw rod is mounted at the screw axle sleeve and the top-loading axle sleeve, and the lower end of the screw rod is mounted on a mounting rack. The utility model is novel and simple in structure, scientific and rational in design, compact and delicate in appearance, and rich in aesthetics. The structure mode that the drum leather supporting ring and the supporting ring holder are used to replace the traditional drum barrel is adopted, which is convenient for carrying, mounting, and adjusting, and the playing effect is better. The utility model is quite applicable for matched playing of a plurality of portable drums in the Latin music.

Description

Portable drum

Technical field

The utility model relates to the bulging class in musical instrument field, particularly a kind of portable drum.

Background technology

Drum is a kind of widely used percussion instrument, particularly in Latin style music, adopt a plurality of drums to cooperate to hit can build show unique characteristics, play in strongly accented rhythms, overflowing with enthusiasm, rough bold and unconstrained music style.The profile and the unitized construction form of drum are single at present, are mostly to adopt drum head is enclosed the structure that is fitted on the drum barrel end face by drum, and there are many shortcomings in the drum of this structure: 1. the overall volume of single drum is bigger, and weight is heavier, and inconvenience is carried; 2. it is bigger to take up room when drum is combined and installed together use with the drum frame, especially cooperates comparatively difficulty of performance simultaneously at a plurality of drums; 3. drum head is installed on the end of drum barrel, and the size of drum barrel is non-adjustable, thereby can not regulate the rate of tension of drum head.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of drum head to press-fit portable drum on a bracing frame by drum circle, thereby makes that this drum has that volume is little, in light weight, good portability, be easy to advantage such as installation adjustment.

The utility model solves its technical matters and takes following technical scheme to realize:

This portable drum is made of drum head, drum circle, metal trim ring, and drum head twines to be contained on the metal trim ring and to be fitted in drum and encloses, and it is characterized in that:

(1). a drum head support ring is installed in the drum head above the metal trim ring, and the axis part of this drum head support ring is fixed with a top dress axle sleeve;

(2). drum circle is by the thereunder parallel support ring stand that is equipped with of the adjusting bolt of its uniform installation of periphery institute, and the axis part of this support ring stand is fixed with a screw rod axle sleeve;

(3). the screw rod axle sleeve that supports ring stand is coaxial with the top dress axle sleeve of drum head support ring and meshes a screw rod is installed that the lower end of this screw rod is installed on the erecting frame.

And described drum head support ring and support ring stand are respectively by entad strut and top dress axle sleeve and screw rod axle sleeve are solidly installed.

And screw rod is by being inlaid at the made guide pillar in its lower end in the made horizontal guide groove of erecting frame, on the screw rod also engagement one lock handle that can locate this screw rod on erecting frame is installed.

Advantage of the present utility model and good effect are:

1. this portable drum adopts drum head support ring, support ring stand to substitute the heavy drum barrel of traditional clumsiness as bracing frame, and this structure has reduced the overall volume and the weight of drum, has improved the portability of drum.

2. this portable bulging compact conformation is especially simple and convenient with the aggregate erection of drum frame, and the rate of tension that can regulate drum head by the mode of barrel tumbler body, reaches effect of saving time and labor.

3. the utility model novel structure is simple, and design science is reasonable, the small and exquisite exquisiteness of profile, create an aesthetic feeling; Employing with the drum head support ring, support the frame mode that ring stand substitutes traditional drum barrel, is easy to carry, installs and adjust, and playing effect is better, be very suitable for the cooperation performance of a plurality of portable drums in the Latin music.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

This portable drum is made of drum head 13, drum circle 1, metal trim ring 15, and drum head twines to be contained on the metal trim ring and to be fitted in drum and encloses, and this portable drum can be installed on one and have on the bulging frame 12 of erecting frame 11.Innovative point of the present utility model is:

(1). a drum head support ring 14 is installed in the drum head above the metal trim ring, the axis part of this drum head support ring is fixed with a top dress axle sleeve 2, the drum head support ring is solidly installed by uniform entad strut 4 and top dress axle sleeve, the horizontal level of this axle sleeve is lower than the horizontal level of drum head support ring, strut contacts with drum head entad to avoid, promptly each entad strut be the inclination divergent shape.

(2). drum circle is by the thereunder parallel support ring stand 6 that is equipped with of the adjusting bolt 5 of its uniform installation of periphery institute, the axis part of this support ring stand is fixed with a screw rod axle sleeve 9, support ring stand and be solidly installed with the screw rod axle sleeve by strut 7 entad, shape is same as the drum head support ring and the shape of strut entad thereof.

(3). the screw rod axle sleeve that supports ring stand is coaxial with the top dress axle sleeve of drum head support ring and meshes a screw rod 3 is installed, this screw rod is threaded onto in the screw rod axle sleeve that supports ring stand and push up in the top dress axle sleeve of the drum head support ring of packing at its top, the lower end of this screw rod is installed on the erecting frame, concrete mounting means is: screw rod is by in the made guide pillar 10 in its lower end is inlaid in the made horizontal guide groove of erecting frame, on the screw rod also engagement one lock handle 8 that can locate this screw rod on erecting frame is installed.In the time need regulating to the rate of tension of drum head, only need the integral body of barrel tumbler to make the support ring stand produce downward axial displacement along screw rod, because drum head support ring top is contained in screw tip and does not produce axial displacement, therefore support ring stand and can will rouse circle tension downwards, simultaneously drum head further is pressed on the drum head support ring downwards by regulating bolt.

Drum head support ring in the present embodiment and support ring stand and inside entad strut for adopting the moulding of kirsite integrally casting, have in light weight, portable advantage; And drum head support ring and support ring stand and the inner entad cross section of strut thereof are ellipse, and smooth surface has beautiful advantage attractive in appearance under the prerequisite that guarantees support strength.When reality is played, a plurality of portable drums with the utility model structure can be installed on the same bulging frame so that cooperate performance.
