Abstract
Description
Technical Field
[0001] This utility model relates to the field of jazz drum technology, specifically to a jazz drum universal turntable device. Background Technology
[0002] The drum kit, also known as a jazz drum set, 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. However, when in use, the drum kit's turntable mechanism generally uses a serrated interlocking fixing structure, which can only achieve angle adjustment in one direction and cannot meet the needs of multi-directional positioning, thus failing to meet the diverse performance requirements. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a universal turntable device for jazz drums, so as to better adjust the turntable angle.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] This utility model provides a jazz drum universal turntable device, including a turntable body, a spherical knurled part, a cymbal boom rod, and a locking assembly;
[0006] The locking assembly is used to lock the turntable body and the knurled spherical part, and the cymbal rod is installed on the knurled spherical part;
[0007] The turntable body has a spherical concave portion at one end facing the spherical knurled part, and the spherical knurled part has a spherical convex portion that mates with the spherical concave portion;
[0008] The locking assembly includes an adjusting shaft that passes through the turntable body and is threadedly connected to a spherical knurled part. A certain gap is formed between the adjusting shaft and the turntable body. The adjusting shaft locks or releases the relative position of the spherical protrusion and the spherical concave part, so that the angle between the turntable body and the spherical knurled part in the horizontal direction is adjustable.
[0009] In some embodiments, the locking assembly further includes a rotary handle disposed at the end of the adjusting shaft away from the knurled part.
[0010] In some embodiments, a spherical metal washer is further included, which is disposed between the turntable body and the rotating handle. The spherical metal washer has a clearance hole to avoid the adjusting shaft and has an arc that conforms to the turntable body.
[0011] In some embodiments, the bottom of the turntable body is provided with an inner diameter connecting pipe and an outer diameter connecting pipe arranged coaxially. The inner diameter connecting pipe is used to insert the cymbal bracket connecting rod, and the outer diameter connecting pipe is used to sleeve the snare drum bracket connecting pipe.
[0012] In some embodiments, the inner diameter connecting pipe has a diameter of 10-14 mm, and the outer diameter connecting pipe has a diameter of 20-24 mm.
[0013] In some embodiments, the spherical protrusions of the knurled part are provided with anti-slip textures.
[0014] In some embodiments, the spherical metal gasket is a hard metal machined part.
[0015] In some embodiments, the cymbal rod is threadedly connected to the spherical knurled part.
[0016] Furthermore, the beneficial effects of this utility model are as follows:
[0017] This invention achieves omnidirectional adjustment at any angle in the horizontal direction through a mating structure of a spherical concave part and a spherical convex part. At the same time, the locking component is used to lock or release the relative position of the spherical convex part and the spherical concave part. When the gap between the spherical convex part and the spherical concave part is released, since there is a certain gap between the adjusting shaft and the turntable body, the angle between the turntable body and the spherical knurled part in the horizontal direction is adjustable. This overcomes the limitation of traditional sawtooth meshing turntables that can only be adjusted on a single axis, and greatly improves the practicality of this invention.
[0018] Meanwhile, by coaxially setting the inner diameter connecting pipe and the outer diameter connecting pipe, a single turntable can be adapted to both the cymbal bracket connecting rod and the drum bracket connecting pipe for universal installation, which significantly reduces the number of special parts and the cost of mold development.

[0024] like Figures 1-3 As shown, this utility model embodiment provides a jazz drum universal turntable device, including a turntable body 2, a spherical knurled part 1, a cymbal boom 7, and a locking assembly;
[0025] The locking assembly is used to lock the turntable body 2 and the spherical knurled part 1, and the cymbal rod 7 is installed on the spherical knurled part 1;
[0026] The turntable body 2 has a spherical concave part at one end facing the spherical knurled part 1, and the spherical knurled part 1 has a spherical convex part 8 that mates with the spherical concave part.
[0027] The locking assembly includes an adjusting shaft 5, which passes through the turntable body 2 and is threadedly connected to the knurled part 1. A certain gap is formed between the adjusting shaft 5 and the turntable body 2. The adjusting shaft 5 locks or releases the relative position of the spherical protrusion 8 and the spherical concave part, allowing the angle between the turntable body 2 and the knurled part 1 in the horizontal direction to be adjustable. The locking assembly also includes a rotating handle 4, located at the end of the adjusting shaft 5 away from the knurled part 1, and a spherical metal washer 3, located between the turntable body 2 and the rotating handle 4. The spherical metal washer 3 has a clearance hole to avoid the adjusting shaft 5 and has an arc that conforms to the turntable body 2. In this structure, when it is necessary to adjust the angle between the knurled part 1 and the turntable body 2, the rotating handle 4 is manually loosened. The adjusting shaft 5 releases the pressure on the spherical metal washer 3, thereby creating a certain gap between the turntable body 2 and the spherical knurled part 1. That is, the spherical protrusion 8 and the spherical concave part are no longer locked together. At this time, the spherical knurled part 1 can be manually deflected to the target angle to achieve axial universal adjustment, or the cymbal lever 7 can be bent horizontally. Since there is a certain gap between the turntable body 2 and the adjusting shaft 5, the cymbal lever 7 can be driven to change the angle in the horizontal direction as a whole. In addition, after positioning, tighten the rotating handle 4 to drive the adjusting shaft 5 to push inward. At the same time, the rotating handle 4 abuts against the spherical metal washer 3, causing the spherical metal washer 3 to move closer to the turntable body 2, forcing the spherical metal washer 3 to press the turntable body 2 against the spherical knurled part 1, completing the angle locking, and thus improving stability.
[0028] In the above embodiments, by adding a matching structure between the spherical concave part and the spherical convex part 8, the omnidirectional adjustment function at any angle in the horizontal direction is realized. At the same time, the locking component is also used to lock or release the relative position of the spherical convex part 8 and the spherical concave part. When the gap between the spherical convex part 8 and the spherical concave part is released, since there is a certain gap between the adjusting shaft 5 and the turntable body 2, the angle between the turntable body 2 and the spherical knurled part 1 in the horizontal direction is adjustable, which overcomes the limitation of the traditional sawtooth meshing turntable that can only be adjusted on a single axis, and greatly improves the practicality of this utility model.
[0029] In one possible implementation, the bottom of the turntable body 2 is provided with an inner diameter connecting pipe 9 and an outer diameter connecting pipe 6 arranged coaxially. The inner diameter connecting pipe 9 is used to insert the cymbal bracket connecting rod, and the outer diameter connecting pipe 6 is used to fit the snare drum bracket connecting pipe. By coaxially arranging the inner diameter connecting pipe 9 and the outer diameter connecting pipe 6, a universal installation that allows a single turntable to simultaneously adapt to both the cymbal bracket connecting rod and the snare drum bracket connecting pipe is achieved, significantly reducing the number of special parts and mold development costs.
[0030] In one possible implementation, the inner diameter connecting pipe 9 has a diameter of 10-14mm, and the outer diameter connecting pipe 6 has a diameter of 20-24mm. In this invention, the inner diameter connecting pipe 9 has a diameter of 12mm, and the outer diameter connecting pipe 6 has a diameter of 22mm. When installing the bracket, the 12mm knurled rod of the cymbal bracket is vertically inserted into the inner diameter connecting pipe 9 at the bottom of the turntable body 2 until the bottom of the pipe, or the 22mm iron pipe of the general drum bracket is sleeved onto the outer wall of the outer diameter connecting pipe 6 from top to bottom, thus completing tool-free quick assembly.
[0031] In one possible implementation, the spherical protrusion 8 of the spherical knurled part 1 has anti-slip textures on its surface. The anti-slip textures of the spherical protrusion 8 and the metal pad between the spherical concave part generate interlocking friction, thereby achieving rigid angle locking and effectively improving stability.
[0032] In one possible implementation, the spherical metal gasket 3 is a machined part of hard metal.
[0033] In one possible implementation, the cymbal rod 7 is threadedly connected to the spherical knurled part 1, wherein the spherical knurled part 1 has a threaded hole for installing the cymbal rod 7, and the threaded connection between the cymbal rod 7 and the spherical knurled part 1 effectively improves the stability of the connection.
[0034] 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.
