Description

Technical Field

[0001] This utility model relates to the field of percussion instrument technology, specifically a musical rhythm percussion instrument. Background Technology

[0002] Percussion instruments, also known as percussion instruments, are an important category of musical instruments. They are usually made to produce sound by striking, shaking, scraping, or rubbing. The performer uses tools such as hands, drumsticks, or mallets to contact the instrument and stimulate it to vibrate, thereby producing sounds with specific timbre, pitch, and rhythm.

[0003] The existing utility model patent with authorization announcement number CN220913890U discloses a musical rhythm percussion instrument. Through the arrangement of a mounting block, a first rotating shaft, a limiting block, a rotating plate, a insert plate, and a support plate, it achieves the following: when playing is required, the fixing pin is pulled out, then the rotating plate is rotated to lower the insert plate downwards, the fixing pin is then inserted to fix the insert plate, and then the insert plate is inserted into the support plate. Anti-detachment pins are used to fix the bass drum. This solves the problem of the inconvenience of disassembling the bass drum and the support, which leads to excessive manpower when moving it and the bass drum being unable to be disassembled during performance. The lack of a fixed structure causes the bass drum to shift, causing great inconvenience to the drummer during performance. The design of the insert rod, limiting spring, second pivot, extension rod, and storage rod solves this problem. After the performance, the bass drum can be disassembled, the limiting pin can be pulled out, the extension rod can be stored in the storage rod, and then the support plate can be rotated while the insert rod compresses the limiting spring. Subsequently, when the support plate is in the upward direction, the limiting spring will pop out the insert rod to limit the support plate. This solves the problem of the large size of the general bass drum support, which takes up a lot of space when not in use.

[0004] While the above technical solution allows for the separation of the bass drum and the stand, and the stand can be folded and extended for easy storage, the drum volume is usually very loud when it is struck, making it inconvenient to adjust. The lack of a volume adjustment mechanism for the drum structure makes it unsuitable for practice in environments requiring high levels of quiet, thus limiting the application scenarios of the drum structure.

[0005] Therefore, those skilled in the art have provided a musical rhythm percussion instrument to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a musical rhythm percussion instrument to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A musical rhythm percussion instrument includes a stand, a bracket fixedly connected to the top of the stand, a drum body disposed inside the bracket, a drumhead fixedly connected to the inner wall of the drum body, and a volume adjustment mechanism disposed inside the drum body.

[0009] The volume adjustment mechanism includes two fixed shells and two support plates. Each fixed shell has a support block slidably connected inside. Each fixed shell has a hand-tightening screw threaded to its inner wall. Each hand-tightening screw has an auxiliary bearing fixedly connected to its outer surface. Each auxiliary bearing has a top plate fixedly connected to its outer surface. Each top plate has an anti-slip pad fixedly connected to its upper surface. Each support plate has two fixed cylinders fixedly connected to its upper surface. Each support plate has a soft-bristled plate above it. Each fixed cylinder has a sliding rod slidably connected inside. Each fixed cylinder has a damper fixedly connected to its inner bottom wall. Each damper has a return spring sleeved on its outer surface.

[0010] As a further embodiment of this utility model: the outer surface of the drum body is in contact with the inner wall of the bracket; the outer surface of each fixed shell is fixedly connected to the inner wall of the drum body; the upper surface of each support block is fixedly connected to the bottom surface of the support plate; the upper surface of each anti-slip pad is in contact with the bottom surface of the support block; the top end of each slide rod is fixedly connected to the bottom surface of the soft board; the telescopic end of each damper is fixedly connected to the bottom end of the slide rod; the two ends of each return spring are respectively in contact with the bottom end of the slide rod and the inner bottom wall of the fixed cylinder; two handle supports are fixedly connected to the outer surface of the bracket; and a pull rod is fixedly connected to the inner wall of each handle support.

[0011] As a further improvement of this utility model: each of the handle supports is provided with a grip inside, and the inner wall of each grip is rotatably connected to the outer surface of the pull rod.

[0012] As a further improvement of this utility model: a first limiting slider is fixedly connected to the front and back of both support blocks, and the outer surface of each first limiting slider is slidably connected to the inside of the fixed shell.

[0013] As a further improvement of this utility model: each of the hand-tightening screws has an anti-slip sleeve fixedly connected to its outer surface, and each of the anti-slip sleeves has several identical anti-slip protrusions fixedly connected to its outer surface.

[0014] As a further improvement of this utility model: two second limiting sliders are fixedly connected to the outer surface of each slider, and the outer surface of each second limiting slider is slidably connected to the inside of the fixed cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the coordinated components of a bracket, support, drum body, drumhead, fixed shell, support block, hand-tightening screw, top plate, auxiliary bearing, anti-slip pad, support plate, fixed cylinder, slide rod, soft burr plate, damper, and return spring. The bracket and support lift the drum body with the drumhead, facilitating the tightening of the hand-tightening screw. With the assistance of the auxiliary bearing, the top plate and anti-slip pad gradually lift the support block within the fixed shell, causing the soft burr plate to gradually approach and press against the bottom surface of the drumhead. The soft burr plate itself has a good cushioning effect, which is further enhanced by the damper and return spring. As the force of the soft burr plate pressing against the bottom surface of the drumhead increases, more vibration energy is absorbed when striking the upper surface of the drumhead, thus significantly reducing the volume produced when striking the drumhead. This effectively adjusts the volume of the drum body and drumhead, expanding the overall application scenarios of the instrument. It avoids the problem of the drum structure being unsuitable for practice in environments requiring high quietness due to the lack of a volume adjustment mechanism, thus limiting its application scenarios.

The outer surface of each fixed shell 501 is fixedly connected to the inner wall of the drum body 3. The upper surface of each support block 502 is fixedly connected to the bottom surface of the support plate 507. Two handle supports 6 are fixedly connected to the outer surface of the bracket 2. A pull rod 7 is fixedly connected to the inner wall of each handle support 6. By setting the pull rod 7, a rotation base surface can be provided for the hand grip structure inside the handle support 6, thereby increasing the flexibility of the hand grip structure. By setting the handle support 6 and the pull rod 7, the entire instrument can be lifted and moved together with the aforementioned hand grip structure.

[0025] Each hand-tightening screw 503 has an auxiliary bearing 505 fixedly connected to its outer surface, and a top plate 504 fixedly connected to the outer surface of each auxiliary bearing 505. Each handle support 6 has a grip 8 inside, and the inner wall of each grip 8 is rotatably connected to the outer surface of the pull rod 7. By setting the grip 8, it is possible to rotate around the outer surface of the pull rod 7 inside the handle support 6, so that the entire instrument can be easily lifted and moved after the grip 8 is held by hand.

[0026] Each top plate 504 has an anti-slip pad 506 fixedly connected to its upper surface. The upper surface of each anti-slip pad 506 is in contact with the bottom surface of the support block 502. Each support plate 507 has two fixed cylinders 508 fixedly connected to its upper surface. The front and back of each support block 502 are fixedly connected to a first limiting slider 9. The outer surface of each first limiting slider 9 is slidably connected to the inside of the fixed shell 501. By setting the first limiting slider 9, it can slide vertically and directionally inside the fixed shell 501, thereby increasing the directional and stable vertical sliding of the support block 502 inside the fixed shell 501.

[0027] Each support plate 507 is provided with a soft board 510 above it. Each fixed cylinder 508 is slidably connected with a slide rod 509 inside. The top of each slide rod 509 is fixedly connected to the bottom surface of the soft board 510. Each hand-tightening screw 503 is fixedly connected with an anti-slip sleeve 11 on its outer surface. Each anti-slip sleeve 11 is fixedly connected with several identical anti-slip protrusions 12 on its outer surface. By setting the anti-slip protrusions 12, the anti-slip properties of the outer surface of the anti-slip sleeve 11 can be increased. By setting the anti-slip sleeve 11 and the anti-slip protrusions 12, the anti-slip properties of the outer surface of the hand-tightening screw 503 can be increased together.

[0028] Each fixed cylinder 508 has a damper 511 fixedly connected to its inner bottom wall. The telescopic end of each damper 511 is fixedly connected to the bottom end of the slide rod 509. Each damper 511 has a return spring 512 sleeved on its outer surface. The two ends of each return spring 512 are in contact with the bottom end of the slide rod 509 and the inner bottom wall of the fixed cylinder 508, respectively. Each slide rod 509 has two second limiting sliders 10 fixedly connected to its outer surface. The outer surface of each second limiting slider 10 is slidably connected to the inside of the fixed cylinder 508. By setting the second limiting sliders 10, the slide rod 509 can slide vertically and directionally inside the fixed cylinder 508, thereby increasing the directionality and stability of the slide rod 509 sliding vertically and directionally relative to the fixed cylinder 508.

[0029] The working principle of this utility model is as follows: In use, the drum body 3 with the drumhead 4 is placed on the bracket 2, and the hand-tightening screw 503 should pass through the reserved opening at the bottom of the bracket 2. When practicing the instrument in a quiet environment, it is necessary to reduce the volume of the drumhead 4. At this time, the two hand-tightening screws 503 are turned respectively. With the assistance of the auxiliary bearing 505, the top plate 504 and the anti-slip pad 506 gradually lift the support block 502 in the fixed shell 501, and make the soft board 510 gradually approach the drumhead 4 until it gradually presses against the bottom surface of the drumhead 4. The soft board 510 itself has a good cushioning effect. With the cooperation of the damper 511 and the return spring 512, the soft board is further enhanced. The cushioning effect of the 510 increases as the soft board 510 presses against the bottom of the drumhead 4, resulting in more vibration energy being absorbed when striking the upper surface of the drumhead 4. This significantly reduces the volume produced when striking the drumhead 4, thus adjusting the volume of the drum body 3 and the drumhead 4 and expanding the overall application scenarios of the instrument. In actual use, the pressing effect of the soft board 510 against the bottom of the drumhead 4 can be adjusted according to the required volume. The design of this musical rhythm percussion instrument effectively solves the problem that the lack of a drum structure volume adjustment mechanism makes it inconvenient to practice in environments requiring high quietness, thus limiting the application scenarios of the drum structure.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
