Description

Technical Field

[0001] The utility model relates to the technical field of drum kits, and specifically relates to a drumstick for a drum kit with adjustable length. Background Art

[0002] A drum kit, that is, a drum set, is a very important percussion instrument in a jazz band. It usually consists of a bass drum played by foot, a snare drum, two or more drums, one or two cymbals, a hi-hat cymbal with a pedal, etc. Of course, sometimes some additional instruments such as cowbells, woodblocks, maracas, triangles, and chimes will be added according to the performance needs. No matter how many additional devices are added, they are all played by one person. The drummer uses drumsticks to strike each component to make it sound. Among them, the drumstick is a tool for hitting the instrument drums and cymbals. There are hundreds of different types and models of drumsticks. Among so many varieties, there are four basic models that each brand will offer: the light and thin 7A type, the general 5A type and 5B type, and the heavier 2B type.

[0003] In modern life, many parents start to pay attention to cultivating their children's extracurricular interests and hobbies from an early age. Among them, music is quite popular among contemporary parents. The drum kit among musical instruments has attracted the attention of parents. It can not only cultivate sentiment but also stimulate children's enthusiasm for progress. Currently, there are a wide variety of drumsticks on the market with different models, which are dazzling. When children are young, they will choose some shorter drumsticks to use. However, as children grow physically, the previous drumsticks will seem too short to use, which affects the performance of the user. At this time, longer drumsticks need to be replaced. And as the child grows, drumsticks need to be replaced successively, which causes economic pressure on the user. At this time, a drumstick for a drum kit with adjustable length is needed.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] In view of the deficiencies and defects in the prior art in the above-mentioned background art that the length of the drumstick cannot be adjusted according to the needs of the user.

[0006] A drumstick for a drum kit with adjustable length disclosed by the utility model includes a fixed cylinder. Two first limiting grooves are provided on the inner wall of the fixed cylinder. A first rack is fixedly connected to the inner wall of each first limiting groove. A connecting cylinder is slidably connected to the inner wall of the fixed cylinder. Two positioning grooves are provided inside the connecting cylinder. A gear is rotatably connected to the inner wall of each positioning groove. The outer surface of each gear meshes with the outer surface of the corresponding first rack. A drumstick is slidably connected to the inner wall of the connecting cylinder. A fixing plate is fixedly connected to the bottom surface of the drumstick. Second racks are fixedly connected to the left side surface and the right side surface of the fixing plate. The outer surface of each second rack meshes with the outer surface of the corresponding gear.

[0007] Furthermore, two second limiting grooves are formed in the outer surface of the drumstick, and the inner walls of each of the second limiting grooves are fixedly connected to the mutually remote side surfaces of the corresponding second racks.

[0008] Furthermore, a first fixing ring is fixedly connected to the top end of the fixed cylinder, and a first fastening ring is fixedly connected to the upper surface of the first fixing ring.

[0009] Furthermore, the inner wall of the first fastening ring is in sliding contact with the outer surface of the connecting cylinder, and a first locking collar is threadedly connected to the outer surface of the first fastening ring.

[0010] Furthermore, a second fixing ring is fixedly connected to the top end of the connecting cylinder, and a second fastening ring is fixedly connected to the upper surface of the second fixing ring.

[0011] Furthermore, the inner wall of the second fastening ring is in sliding contact with the outer surface of the drumstick, and a second locking collar is threadedly connected to the outer surface of the second fastening ring.

[0012] Furthermore, anti-slip abrasive patterns arranged at equal intervals are fixedly connected to the outer surface of the fixed cylinder, and a mallet head is fixedly connected to the top end of the drumstick.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing components such as a first rack, a gear, and a second rack, the present utility model drives the fixing plate to move upward by pulling the drumstick. The fixing plate drives the second rack to engage with the corresponding gear and drives the gear to rotate. At the same time, the gear engages with the corresponding first rack, causing the connecting cylinder to move upward, thereby achieving the effect that the length of the drumstick of the device can be accurately adjusted.

[0015] 2. By providing components such as a first fastening ring, a first locking collar, a second fastening ring, and a second locking collar, when the drumstick and the connecting cylinder rise to an appropriate position, the second locking collar is rotated to compress the second fastening ring, so that the second fastening ring clamps the drumstick and locks the position of the drumstick. At the same time, the first locking collar is rotated to compress the first fastening ring, so that the first fastening ring clamps the connecting cylinder and locks the position of the connecting cylinder, thereby achieving the effect that the device can lock the positions of the connecting cylinder and the drumstick to prevent accidental elongation during drumming.
