Description

Technical Field

[0001] This utility model relates to the field of jazz drum technology, specifically to a fixing device for jazz drum cymbal hangers. Background Technology

[0002] A drum kit, also known as a jazz drum kit, is a very important percussion instrument in a jazz band. It typically consists of a bass drum with a foot pedal, a snare drum, two or more tom-toms, one or two crash cymbals, a rhythm cymbal, and a hi-hat with a pedal. The crash cymbals are fixedly connected via a turntable. During use, the height of the crash cymbals needs to be constantly adjusted to adapt to different playing needs. However, existing turntables use a serrated engagement method. When adjusting the height of the crash cymbal, the serrated engagement must be completely disengaged to adjust the position. The adjustment process is complicated and cannot achieve millimeter-level fine adjustments of the crash cymbal simultaneously during performance, resulting in insufficient cymbal positioning accuracy. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a fixing device for the cymbal hanger of a jazz drum, so as to achieve better adjustment of the cymbal hanger.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a fixing device for a jazz drum cymbal hanger, comprising: a turntable body, a fixing component, a tightening nut, a universal wrench, and a cymbal hanger; The fixing member and the turntable body are fixedly connected by complementary conical meshing surfaces. The tightening nut is disposed on the turntable body and located between the turntable body and the fixing member. The tightening nut has a first locking hole for accommodating the cymbal rod. The fixing member has a second locking hole for accommodating the cymbal rod. The universal wrench is disposed on the turntable body and is used to drive the tightening nut to reciprocate horizontally. When the cymbal rod passes through the second locking hole and the first locking hole in sequence, the universal wrench drives the tightening nut to move horizontally so that the first locking hole and the second locking hole are misaligned and lock the cymbal rod.

[0005] In some embodiments, an arc-shaped gasket is also included, disposed between the turntable body part and the universal wrench.

[0006] In some embodiments, the tightening nut is threadedly connected to the turntable body part, with the first locking hole at one end and a mating end that mates with the universal wrench at the other end.

[0007] In some embodiments, the universal wrench is threadedly engaged with the mating end to drive the tightening nut to move axially.

[0008] In some embodiments, the diameter of the first locking hole is larger than the diameter of the cymbal rod, and the diameter of the second locking hole is larger than the diameter of the cymbal rod.

[0009] In some embodiments, the turntable body part is provided with a first conical mating surface, and the fixing member is provided with a second conical mating surface, the second conical mating surface engaging and locking with the first conical mating surface.

[0010] In some embodiments, the contact surfaces between the first tapered mating surface and the second tapered mating surface are provided with toothed structures.

[0011] In some embodiments, the first tapered mating surface and the second tapered mating surface have the same cone angle, which ranges from 30° to 60°.

[0012] Furthermore, the beneficial effects of this utility model are as follows: This invention features a first and second conical mating surface that cooperate with each other, with complementary conical meshing surfaces providing a basic rigid locking mechanism. Furthermore, the horizontal displacement of the tightening nut causes a misalignment between the first and second locking holes, allowing the cymbal boom to be abutted against the side walls of both holes. This slight misalignment locks the boom into the fixing component. When adjustment is needed, a universal wrench is manually rotated to drive the tightening nut horizontally, aligning the first and second locking holes. This allows the boom to be pulled out of these holes, thus adjusting its height. Overall, this invention enables precise single-handed adjustment of the boom and synchronous adjustment during performance, effectively improving stability. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. In addition, in the description of the embodiments of the present utility model, "multiple" means two or more. Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this utility model, unless otherwise stated, "multiple" means two or more.

[0016] like Figures 1-5 As shown, this utility model embodiment provides a fixing device for a jazz drum cymbal hanger, including: a turntable body part 3, a fixing part 1, a tightening nut 2, a universal wrench 5, and a cymbal hanger 6; The fixing component 1 is fixedly connected to the turntable body part 3 through complementary conical meshing surfaces. The tightening nut 2 is set on the turntable body part 3 and located between the turntable body part 3 and the fixing component 1. The tightening nut 2 has a first locking hole 21 for accommodating the cymbal rod 6. The fixing component 1 has a second locking hole 11 for accommodating the cymbal rod 6. The universal wrench 5 is set on the turntable body part 3 and is used to drive the tightening nut 2 to reciprocate horizontally. When the cymbal rod 6 passes through the second locking hole 11 and the first locking hole 21 in sequence, the universal wrench 5 drives the tightening nut 2 to move horizontally, so that the first locking hole 21 and the second locking hole 11 are misaligned to lock the cymbal. The specific process for rod 6 is as follows: the tightening nut 2 is screwed into the threaded hole of the turntable body part 3. At this time, the first locking hole 21 and the second locking hole 11 are coaxial. After the cymbal rod 6 passes through the first locking hole 21 and the second locking hole 11 in sequence, it is in a non-locked state. At this time, the first locking hole 21 and the second locking hole 11 are coaxially aligned, allowing the rod to slide freely. When the universal wrench 5 is manually tightened, its threaded end drives the tightening nut 2 to move horizontally. The first locking hole 21 is opened and moves towards the turntable body part 3, causing the first locking hole 21 and the second locking hole 11 to be radially misaligned. The staggered steps formed by the misalignment apply multi-point friction locking to the surface of the cymbal rod 6.

[0017] This invention provides a basic rigid locking mechanism by providing a first conical mating surface and a second conical mating surface that cooperate with each other, where the two mating surfaces have complementary conical meshing surfaces. Furthermore, the horizontal displacement of the tightening nut 2 causes a misalignment between the first locking hole 21 and the second locking hole 11, resulting in the cymbal rod 6 being abutted against the side walls of both the first locking hole 21 and the second locking hole 11. This slight misalignment of the first locking hole 21 and the second locking hole 11 effectively locks the cymbal rod 6 into the interior of the fixing member 1. (See reference [link to specific details]). Figure 4 , Figure 5 , Figure 4 This is a schematic diagram of the non-extended cymbal suspension rod 6 in the fixing device for the jazz drum suspension rod provided by this utility model. Figure 5 This is a schematic diagram of the extended structure of the cymbal boom 6 in the fixing device for the jazz drum boom provided by this utility model. When adjustment is required, the universal wrench 5 is manually rotated to drive the tightening nut 2 to move horizontally, thereby making the first locking hole 21 and the second locking hole 11 aligned, so that the cymbal boom 6 can be pulled out from inside the first locking hole 21 and the second locking hole 11, thus completing the height adjustment process of the cymbal boom 6. This utility model as a whole realizes precise adjustment of the cymbal boom by one hand and synchronous adjustment during performance, effectively improving stability.

[0018] One possible implementation also includes an arc-shaped washer 4, which is disposed between the turntable body part 3 and the universal wrench 5. The arc-shaped washer 4 is disposed between the universal wrench 5 and the turntable body part 3, and the load is evenly distributed through spherical deformation during the locking process.

[0019] In one possible implementation, the tightening nut 2 is threadedly connected to the turntable body part 3, with a first locking hole 21 at one end and a mating end that engages with the universal wrench 5 at the other end. The universal wrench 5 engages with the mating end threadedly, driving the tightening nut 2 to move axially, thereby completing the process of locking or unlocking the cymbal rod 6.

[0020] In one possible implementation, the diameter of the first locking hole 21 is larger than the diameter of the cymbal rod 6, and the diameter of the second locking hole 11 is larger than the diameter of the cymbal rod 6. In the above structure, the diameter of the first locking hole 21 is larger than the diameter of the cymbal rod 6, and the diameter of the second locking hole 11 is larger than the diameter of the cymbal rod 6, to ensure that there is no obstruction when the cymbal rod 6 slides.

[0021] In one possible implementation, the turntable body part 3 has a first conical mating surface, and the fixing member 1 has a second conical mating surface. The second conical mating surface engages and locks with the first conical mating surface. Both the first and second conical mating surfaces have toothed structures on their contact surfaces. During assembly, the conical mating surface of the turntable body part 3 is first engaged with the corresponding conical surface of the toothed fixing member 1. The contact surfaces are machined with toothed structures to enhance torsional resistance. In this structure, the turntable body part 3 is equipped with a first conical mating surface, while the fixing member 1 has a second conical mating surface. These two conical mating surfaces engage with each other to achieve a locking function. During assembly, the conical mating surface of the turntable body part 3 is first engaged with the corresponding conical surface of the toothed fixing member 1. Furthermore, the contact surfaces are specially machined to form toothed structures that enhance torsional resistance.

[0022] In one possible implementation, the first conical mating surface and the second conical mating surface have the same cone angle, ranging from 30° to 60°. In this invention, 45° is preferred. With the above design, the 45° first conical mating surface and the second conical mating surface can fit together better, effectively improving stability. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
