Description

Technical Field

[0001] This utility model relates to the field of kahund drum manufacturing and processing technology, specifically an octagonal kahund drum. Background Technology

[0002] The cajon, also known as a box drum or wooden box drum, is a box-shaped wooden percussion instrument. The cajon has multiple sides, each with a different sound. It is usually filled with steel wire to create resonance and produce a sound similar to that of a jazz drum.

[0003] The existing cajon drums have their internal sound strings fixed by bolts, which cannot be quickly adjusted. The fixed tension of the sound strings means that the tone of the cajon drum is relatively fixed, which makes the tone too monotonous and limits its application in various musical scenarios. If the sound strings are in an unsuitable tension for a long time, it will affect the lifespan and performance of the cajon drum, thus limiting its capabilities.

[0004] The reason for this problem is that in the current performance environment, performers need to adjust the timbre according to the needs of the music. The existing cajon drum cannot quickly adjust the tension of the snare, which limits the flexibility and diversity of the performance. The inability to quickly adjust the tension of the snare limits the performer's ability to express certain musical details and techniques, and prevents them from fully demonstrating their performance capabilities. If the snare is in an unsuitable tension for a long time, it will cause additional wear or damage to the drumhead, tuning pegs and other components, thus affecting the lifespan of the cajon drum. Therefore, we propose the octagonal cajon drum to solve the above problems. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides an octagonal cajon, which solves the problem that the internal sound strings of existing cajons are fixed by bolts, making quick adjustment impossible. The fixed tension of the sound strings means that the cajon's tone is relatively fixed, which makes the cajon's tone too monotonous and limits its application in various musical scenarios. The sound strings being in an unsuitable tension state for a long time will affect the cajon's service life and performance, thus presenting limitations.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model embodiment discloses an octagonal card drum.

[0029] According to the appendix Figure 1-6 As shown, it includes a drum body 1, and a rattle belt 2 is provided inside the drum body 1. A tension adjustment mechanism 3 is provided on one side of the rattle belt 2. The tension adjustment mechanism 3 includes a worm gear 31, a worm 32, a rotating shaft 33 and a pull rope 34.

[0030] When installing the snare 22, insert the second fixing strip 23 through the hole at the bottom of the drum body 1 into the inside of the drum body 1, tighten the fixing bolt 24, grasp the first fixing strip 21, and pull it to one side so that the fixing ring 45 is engaged in the inside of the hook 42. At this time, the installation of the snare 22 is completed. When it is necessary to adjust the tension of the snare 22, rotate the worm gear 32 clockwise. The worm gear 32 drives the worm wheel 31 to rotate, so that the rotating shaft 33 also rotates synchronously, tightening the pull rope 34 to achieve the required tension. Release the worm gear 32 to complete the adjustment. This device can complete the installation and adjustment of the snare belt 2 with one hand, which is very convenient and meets the needs of users.

[0031] The worm 32 is located on one side of the worm wheel 31, and the worm wheel 31 meshes with the worm 32. The rotating shaft 33 passes through the worm wheel 31, and the worm wheel 31 is fixedly connected to the rotating shaft 33. The pull rope 34 is wound around the outer surface of the rotating shaft 33.

[0032] The end of the pull rope 34 is fixedly connected to a clip 4, which is movable with the rattle belt 2.

[0033] The snare belt 2 includes a first fixing strip 21, a snare 22, a second fixing strip 23, and a fixing bolt 24; one end of the snare 22 is fixedly connected to the first fixing strip 21, and one end of the snare 22 is fixedly connected to the second fixing strip 23; the end of the first fixing strip 21 abuts against the drum body 1; the fixing bolt 24 is movably inserted into the inside of the second fixing strip 23; and the fixing bolt 24 is threadedly connected to the drum body 1.

[0034] A positioning block 35 is fixedly connected to one side of the drum body 1. A worm gear 32 is rotatably connected inside the positioning block 35. A baffle 36 is fixedly connected to the outer surface of the rotating shaft 33. The locking component 4 includes a fixing block 41, a hook 42, a limiting strip 43, and a fixing ring 45. The fixing block 41 is fixedly connected to the pull rope 34. The hook 42 is rotatably connected to one side of the fixing block 41. The limiting strip 43 is rotatably connected inside the hook 42. The fixing ring 45 is fixedly connected to one side of the first fixing strip 21. The hook 42 is movably locked inside the fixing ring 45. The locking component 4 also includes a torsion spring 44. The torsion spring 44 is rotatably connected inside the hook 42. One end of the torsion spring 44 is fixedly connected to the hook 42, and the other end of the torsion spring 44 is fixed to the limiting strip 43. The baffle 36 is fixedly connected to the outer surface of the rotating shaft 33. Its function is to prevent the pull rope 34 from piling up next to the worm gear 31 when the rotating shaft 33 winds the pull rope 34, thus affecting the meshing of the worm gear 31 and the worm 32 and ensuring the normal use of the device. The torsion spring 44 is used to lock the limit strip 43 inside the hook 42 during normal use, so that the hook 42 cannot fall off from the inside of the fixing ring 45. When disassembly is required, the worm 32 is rotated to loosen the pull rope 34 and the limit strip 43 is pressed inward. At this time, the torsion spring 44 is tightened. After the hook 42 is removed, the limit strip 43 is released. Under the reaction force of the torsion spring 44, the limit strip 43 automatically resets, ready for the next use, thus meeting the user's needs.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
