Description

Technical Field

[0001] The utility model relates to the technical field of electronic drum accessories, and particularly relates to an adjustable fixing chuck for an electronic drum head. Background Art

[0002] At present, for electronic drum products on the market, the connection method between the drum head and the drum rack usually adopts a fixing chuck. The existing similar electronic drum racks have the following defects: Due to the limitation of the drum tube chuck, the drum head can only be adjusted in height up and down and in position horizontally left and right, but the drum head cannot be adjusted in tilt angle up and down or left and right, which cannot meet the position adjustment and placement requirements of all players for the drum head. And it cannot meet the usage habits and gestures of all players for position adjustment, affecting the usage experience.

[0003] For example, the patent with publication number CN215118285U discloses a drum head connecting piece and a drum kit, including a base, a first movable block, a second movable block, and an adjusting piece. The first side of the first movable block is rotatably connected to the base, the second side of the first movable block is threadedly connected to the base through a first thread, and a hollow part is formed between the middle part of the first movable block and the base; the first side of the second movable block is rotatably connected to the base, the second side of the second movable block is threadedly connected to the base through a second thread, and a spherical accommodating cavity part is formed between the middle part of the second movable block and the base. The accommodating cavity part has a through hole communicating with the outside; the adjusting piece includes an adjusting rod and a sphere fixedly arranged at one end of the adjusting rod. The sphere is placed in the accommodating cavity part, and the adjusting rod passes through the through hole.

[0004] The above-mentioned drum head connecting piece includes a base, a first movable block, a second movable block and an adjusting piece. The first side of the first movable block is rotatably connected to the base, the second side of the first movable block is threadedly connected to the base through a first thread, the first side of the second movable block is rotatably connected to the base, and the second side of the second movable block is threadedly connected to the base through a second thread. Based on the above structure, there are problems of complex structure and cumbersome installation;

[0005] Based on the above structure in actual application, after fixing the drum head to the adjusting rod, the angle of the drum head can be adjusted by rotating the sphere;

[0006] However, since the adjusting rod and the sphere are of an integral structure, the distance between the adjusting rod and the sphere cannot be changed, and thus the distance between the drum head and the drum tube cannot be adjusted. There is a problem of low applicability. When it is necessary to adjust the distance between the drum head and the drum tube, it is only possible to disassemble the connection between the drum head and the adjusting rod, then move the drum head along the adjusting rod to adjust the distance between the drum head and the drum tube, and finally reconnect the drum head and the adjusting rod, resulting in cumbersome operation.

[0007] Therefore, it can be seen that providing a drum disc fixing chuck with high applicability and simple structure is an urgent problem to be solved in this field. Summary of the Utility Model

The base body and the cover plate are connected to form a receiving cavity portion adapted to the deformable sphere. The deformable sphere is provided with a through hole and is placed in the receiving cavity portion. The adjusting rod is movably inserted through the through hole. Through the connection between the cover plate and the base body, the deformable sphere located in the receiving cavity portion can be squeezed, so that the deformable sphere is deformed by squeezing and clamps and fixes the adjusting rod.

[0027] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific illustrations.

[0028] In view of the technical problems of the existing drum disc chucks with low applicability and complex structures, based on these technical problems, the present utility model provides an adjustable electronic drum disc fixing chuck. By adopting a split-type adjusting member, the distance between the adjusting rod and the deformable sphere can be freely adjusted, so as to adjust the angle of the drum disc and the distance between the drum disc and the drum tube at the same time, and the structure is simple and the operation is simple, greatly improving the applicability of the drum disc chuck.

[0029] See Figure 1 , which shows a three-dimensional exploded structural schematic diagram of the adjustable electronic drum disc fixing chuck provided by the present utility model.

[0030] It can be seen from the figure that the adjustable electronic drum disc fixing chuck provided by the present utility model includes four components: a base 100, a cover plate 200, a deformable sphere 300, and an adjusting rod 400.

[0031] The base 100 and the cover plate 200 are the structural main bodies of this solution, and the two are connected in cooperation to form the housing of this chuck to carry other components.

[0032] Among them, the base 100 includes a base body 110 and a drum tube connecting portion 120 extending outward from the base body 110, and the drum tube connecting portion 120 is used for connecting with the drum tube.

[0033] Furthermore, one side of the base body 110 and the cover plate 200 is rotatably connected, and the other side is detachably connected. The base body 110 and the cover plate 200 form an accommodating cavity portion 220 through cooperation connection;

[0034] The deformable sphere 300 is arranged in the accommodating cavity portion 220, and a through hole 310 is provided on the deformable sphere 300. The adjusting rod 400 is integrally movably inserted into the through hole 310, and one end of the adjusting rod 400 is used for cooperating with the electronic drum disc.

[0035] Through the connection between the cover plate 200 and the base body 110, the deformable sphere 300 located in the accommodating cavity portion 220 can be squeezed. The deformable sphere 300 is configured as a deformable structure so that the deformable sphere 300 is deformed by the extrusion and clamps and fixes the adjusting rod 400.

[0036] Based on the above structure, since one side of the base body 100 and the cover plate 200 is detachably connected, and in this embodiment, threaded connection is adopted, so the base body 100 and the cover plate 200 can respectively form an adjustment state and a fixed state through disassembly and connection.

[0037] By disassembling the connection between the base body 100 and the cover plate 200 to form an adjustment state, at this time, the deformable sphere 300 can rotate relative to the accommodation cavity portion 220, and the adjusting rod 400 can move relative to the through hole 310. At this time, by moving the adjusting rod 400 in the through hole 310 and simultaneously driving the deformable sphere 300 to rotate in the accommodation cavity portion 220, the angle and position adjustment of the electronic drum disc connected to the adjusting rod 400 can be realized;

[0038] By fastening the connection between the base body 100 and the cover plate 200 to form a fixed state, after connection, the deformable sphere 300 in the accommodation cavity portion 220 can be extruded, so that the deformable sphere 300 is fixed in the accommodation cavity portion 220, and the deformable sphere 300 is deformed by extrusion and can clamp and fix the adjusting rod 400, thereby realizing the fixation of the electronic drum disc after angle adjustment and position adjustment.

[0039] Compared with the prior art in which the first movable block and the base are cooperatively connected to form a hollow part for connecting with the drum tube, the first movable block and the base adopt a split structure, which has problems such as complex structure and cumbersome assembly; in the adjustable electronic drum disc fixing chuck provided by this solution, the drum tube connecting portion 120 is used to connect with the drum tube, and the drum tube connecting portion 120 is an integral structure, which has the beneficial effects of simple structure and convenient installation;

[0040] And only by disassembling the connection between the base body 100 and the cover plate 200, moving the adjusting rod 400 in the through hole 310 and simultaneously driving the deformable sphere 300 to rotate in the accommodation cavity portion 220, the angle and position adjustment of the electronic drum disc connected to the adjusting rod 400 can be realized, which can well solve the problem that only the angle of the electronic drum disc can be adjusted during adjustment in the prior art.

[0041] The following describes the specific composition of the adjustable electronic drum disc fixing chuck provided by the present invention in conjunction with the accompanying drawings.

[0042] Specifically, the base 100 includes a base body 110 and a drum tube connecting portion 120 extending outward from the base body 110.

[0043] The base body 110 is integrally block-shaped, and a first groove 130 is provided at one end thereof. The first groove 130 cooperates with the cover plate 200, and the deformable sphere 300 can be placed therein.

[0044] The drum tube connecting part 120 includes a non-closed C-shaped clamping groove 121 which cooperates with the drum tube and can accommodate the drum tube to pass through it. At the same time, two clamping arms 122 are formed outwardly opposite to each other at both ends of the C-shaped clamping groove 121. A first through hole 123 and a second through hole 124 are respectively provided on the two opposite clamping arms 122, and the first through hole 123 and the second through hole 124 can be penetrated by a fastener and threadedly connected.

[0045] Specifically, the first bolt 1 is passed through the first through hole 123 and the second through hole 124 in sequence and the first metal gasket 2 is sleeved. Then, the first nut 3 is embedded in the first plastic ingot part 4, and by rotating the first plastic ingot part 4, the first nut 3 embedded in it is matched with the first bolt 1 to realize the clamping between the two clamping arms 122, and then drive the C-shaped clamping groove 121 to clamp the drum tube passing through it.

[0046] In the actual application process, only by rotating the first plastic ingot part 4 to adjust the tightness of the first nut 3 and the first bolt 1 embedded in it, the tightness of the two clamping arms 122 clamping the drum tube can be adjusted, and the operation is convenient.

[0047] The base body 110 and the cover plate 200 with such a structure are connected to realize clamping the deformable sphere 300 therein. A second groove 210 is provided on the cover plate 200, and the second groove 210 and the first groove 130 on the base body 110 cooperate to form a receiving cavity part 220, and the receiving cavity part 220 is adapted to the deformable sphere 300 and can accommodate the deformable sphere 300 to be placed therein and rotate freely.

[0048] In some embodiments of the present invention, a plurality of limiting grooves 221 are provided on the side wall of the receiving cavity part 220 for limiting the deformable sphere 300 placed in the receiving cavity part 220, so that the deformable sphere 300 is more stably and reliably fixed in the receiving cavity part 220.

[0049] As an example, the following specifically describes the preferred implementation manner in which one side of the base body 110 and the cover plate 200 in this example is rotatably connected and the other side is detachably fixedly connected.

[0050] On this basis, two opposite through holes are provided on one side of the base body 110, and corresponding through holes are provided on the cover plate 200. The base body 100 and the cover plate 200 are connected by a fixing pin 5 and a retaining ring 6. The fixing pin 5 is passed through the through holes on the base body 110 and the cover plate 200, and the retaining ring 6 is sleeved on the fixing pin 5 to clamp it, realizing the rotatable connection between the cover plate 200 and the base body 100.

[0051] In this embodiment, the other side preferably adopts a threaded connection method. Specifically, a third through hole 111 is provided on the other side of the base body 110, and a fourth through hole 201 corresponding to the third through hole 110 is provided on the cover plate 200. The second bolt 7 is sequentially passed through the third through hole 111 and the fourth through hole 201 and sleeved with a second metal gasket 8. Then, the second nut 9 is embedded in the second plastic ingot part 10. By rotating the second plastic ingot part 10, the second nut 9 embedded therein is matched with the second bolt 7 to realize the detachable fixed connection between the base body 110 and the cover plate 200, and then the deformable sphere 300 placed in the accommodation cavity part 220 is clamped.

[0052] When the drum disc angle needs to be adjusted, only need to rotate the second plastic ingot part 10 to make the connection between the second nut 9 in the second plastic ingot part 10 and the second bolt 7 loose. The base body 110 and the cover plate 200 are driven by the fixed pin 5 to rotate, so that the base body 110 and the cover plate 200 move relatively away from each other. Furthermore, the deformable sphere 300 can rotate freely in the accommodation cavity part 220. When the required angle is adjusted, only need to rotate the second plastic ingot part 10 again to fix the base body 110 and the cover plate 200. At this time, the base body 110 and the cover plate 200 move relatively closer to each other, and then the deformable sphere 300 is clamped in the accommodation cavity part 220.

[0053] A through hole 310 adapted to the adjusting rod 400 is provided on the deformable sphere 300. The through hole 310 is matched with the adjusting rod 400 and can accommodate the adjusting rod 400 to pass through it.

[0054] In order to improve the reliability of the connection between the adjusting rod 400 and the deformable sphere 300, the through hole 310 on the deformable sphere 300 is a polygonal hole, and the adjusting rod 400 adopts a polygonal structure adapted to the polygonal hole. Since the polygonal structure is more stable and reliable than the circular structure and can limit the relative rotation between the two, therefore, the reliability of the connection between the adjusting rod 400 and the deformable sphere 300 can be effectively improved.

[0055] The deformable sphere 300 preferably adopts a deformable sphere with elasticity. When the deformable sphere 300 is squeezed, it can deform so that the space of the through hole 310 becomes smaller, thereby clamping the adjusting rod 400 in the through hole 310. When the extrusion force on the deformable sphere 300 disappears, the deformable sphere 300 can recover as before due to the elastic restoring force.

[0056] On this basis, a number of notch groups 310 are provided on the deformable sphere 300. The number of notch groups 310 is arranged at equal intervals along the circumferential direction on the side wall of the deformable sphere 300. The notch group 310 communicates with the through hole 310. The number of notch groups 310 can form a deformation groove, so that the deformation amount of the deformable sphere 300 increases when an external force is applied, and the stress of the deformable sphere 300 is increased.

[0057] The adjusting rod 400 is inserted into the through hole 310. By rotating the second plastic ingot 10, the base body 110 and the cover plate 200 are relatively close to each other. At this time, the deformable sphere 300 is deformed by the extrusion force, and thus the adjusting rod 400 arranged in the through hole 310 of the deformable sphere 300 is clamped and fixed. When the distance between the drum disc and the drum tube needs to be adjusted, only by rotating the second plastic ingot 10, the base body 110 and the cover plate 200 are relatively far away from each other. The deformable sphere 300 is deformed due to the elastic restoring force. At this time, the adjusting rod 400 can axially move in the through hole 310. After adjusting to the corresponding position, rotating the second plastic ingot 10 again can fix the adjusting rod 400 in the deformable sphere 300.

[0058] The notch group 310 includes a first notch 311 and a second notch 312, and the first notch 311 and the second notch 312 communicate with the through hole 310.

[0059] Furthermore, the first notch 311 extends downward along the orifice at one end of the through hole 310 of the deformable sphere 300, and the second notch 312 extends upward along the orifice at the other end of the through hole 310 of the deformable sphere 300. The first notch 311 and the second notch 312 are arranged in an interleaved manner. Such an arrangement can make the stress distribution formed by the extrusion of the deformable sphere 300 uniform, improve the service life of the deformable sphere 300, and improve the connection reliability with the adjusting rod 400.

[0060] In some embodiments of the present invention, a number of protrusions 313 and a number of grooves 314 are further provided on the deformable sphere 300, which further improves the friction of the deformable sphere 300, making the connection between the deformable sphere 300 and the base 110 and the cover plate 200 more stable and reliable.

[0061] Such as Figure 3 , the adjusting rod 400 is integrally L-shaped, the outer surface is a polygonal structure, one end is inserted into the through hole 310 of the deformable sphere 300. By moving the position of the adjusting rod 400 in the through hole 310, the distance between the drum disc and the drum tube can be changed, and it is fixed in the through hole 310 by rotating the second plastic ingot 10. The other end is fixedly connected to the drum disc. In the actual application process, only by moving the drum disc up, down, left, and right can the angle be adjusted.

[0062] The working process of the present utility model in specific applications is illustrated by the following examples. It should be noted here that the content described is only a specific application example of this solution and does not limit this solution.

[0063] First, insert the drum tube into the C-shaped clamping groove 121, and fix the drum tube in the C-shaped clamping groove 121 by rotating the first plastic ingot 4. Then, place the deformable sphere 300 in the accommodating cavity part 220. Immediately afterwards, insert one end of the adjusting rod 400 into the through hole 310 of the deformable sphere 300. According to actual usage requirements, move the adjusting rod 400 so that the adjusting rod 400 axially moves in the through hole 310. By rotating the second plastic ingot part 10, the deformable sphere 300 is squeezed and fixed in the accommodating cavity part 220. Since the deformable sphere 300 deforms under external force extrusion, the adjusting rod 400 is fixed in the through hole 310. Finally, fixedly connect the other end of the adjusting rod 400 to the drum disc, thereby fixing the drum disc and the drum tube.

[0064] When the angle of the drum disc needs to be adjusted, just rotate the second plastic ingot part 10 to loosen the connection between the cover plate 200 and the base 100. The cover plate 200 and the base 100 move relatively away from each other, so that the deformable sphere 300 can freely rotate in the accommodating cavity part 220. By moving the drum disc fixed to the adjusting rod 400, and the adjusting rod 400 is also connected to the deformable sphere 300, due to the transmission of motion, the drum disc can be adjusted at different angles. It is also possible to move the adjusting rod 400 simultaneously so that it moves in the through hole 310 of the deformable sphere 300, thereby adjusting the distance between the drum disc and the drum tube. Finally, rotation of the second plastic ingot part 10 can complete the fixation.

[0065] Furthermore, in order to improve the reliability of the connection between the fixed chuck and the drum tube as well as the drum disc, an anti-slip layer is coated on the inner surfaces of the C-shaped clamping groove 121 and the accommodating cavity part 220. The anti-slip layer can increase the friction between the drum tube and the C-shaped clamping groove 121, as well as increase the friction between the deformable sphere 300 and the accommodating cavity part 220, thereby improving the connection reliability between the drum disc connected to the deformable sphere 300 through the adjusting rod 400 and the connection reliability between the drum tube and the C-shaped clamping groove 121.

[0066] The specific composition of the anti-slip layer in this solution is not limited and can be determined according to actual requirements. As an example, a polyurethane coating or a polymer coating can be used.

[0067] For the adjustable electronic drum disc fixed chuck provided by the present utility model, due to the split design of the deformable sphere 300 and the adjusting rod 400, the angle of the drum disc can be adjusted while the distance between the drum disc and the drum tube can be adjusted by moving the adjusting rod 400, greatly improving the applicability. Moreover, the structure is simple and the operation is convenient, which can meet the usage requirements of different users.

[0068] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
