Description

Technical Field

[0001] The utility model relates to the technical field of electronic drum racks, and in particular to a supporting rod structure of an electronic drum rack. Background Art

[0002] At present, in the electronic musical instrument industry, the existing electronic drum sets on the market need to reassemble the drum frame and install the sound source, drum plate, cymbals, etc. every time they are performed outside. After the performance, the assembled drum frame and the installed sound source, drum plate, cymbals, etc. must be disassembled. However, the existing electronic drum frames are assembled through several vertical pipes, horizontal pipes and pipe buckles. The assembly is cumbersome, the volume is large, and it is not easy to carry, which brings certain troubles to the performers. In particular, the storage problem of the bottom support rod part has not been effectively solved.

[0003] In the prior art, for example, patent CN220367739U discloses a foldable drum stand, in which the support structure at the bottom includes a first support rod and a second support rod, wherein the first support rod, the second support rod and the column form a "human" shaped structure, wherein the first support rod and the column cannot rotate, and the electronic drum stand can be folded and stored only by rotating the second support rod toward the side close to the first support rod so that the second support rod is parallel to and abuts against the side of the first support rod. Although this storage structure realizes storage in the horizontal direction and reduces the area, the length dimension in the vertical direction is still not significantly improved; especially in the structure of the support rod of the electronic drum stand, since a suitcase structure needs to be specially designed as an outer packaging, the outer packaging is too large in size, which will increase the cost both in terms of cost and transportation, so the smaller the size of the overall drum stand in the final storage state is, the better. In addition to realizing storage and size reduction in the horizontal direction, it is also necessary to further reduce the length dimension in the vertical direction to better save packaging costs. Utility Model Content

[0004] In order to overcome at least one defect in the above prior art, the utility model provides an electronic drum stand support rod structure, which has a simple structure, can realize bidirectional rotation, is easy to store, and has a small volume after storage, which is convenient for packaging and transportation.

[0005] The utility model provides an electronic drum rack support rod structure: comprising a first support rod and a second support rod connected to the lower end of a column of the electronic drum rack, the upper ends of the first support rod and the second support rod are rotatably connected to the two sides of the lower end of the column respectively; the first support rod and the second support rod can be opened to a supporting position along a direction of separation from each other in a YZ plane and can be rotated to a storage position along a direction of approaching each other, and a limiting part for limiting the supporting position and the storage position is provided between the first support rod and the column and between the second support rod and the column.

[0011] The second joint also includes an annular second plug plate, the second connecting column is located in the second plug plate, and a second limit block is provided on the outer wall of the second connecting column, the fourth joint includes an annular second slot and a second abutment block, the second plug plate can be rotatably fitted in the second slot, and when the second support rod is rotated in the clockwise direction to the first extreme position, the third abutment surface of the second abutment block abuts against the third limit surface of the second limit block, and when the second support rod is rotated in the counterclockwise direction to the second extreme position, the fourth abutment surface of the second abutment block abuts against the fourth limit surface of the second limit block.

[0012] Furthermore, the third joint also includes a first plug inserted into the first support rod, the first plug is provided with a first countersunk through hole for passing the first bolt, and the upper end of the first support rod is provided with a first connecting hole corresponding to the first countersunk through hole; the fourth joint also includes a second plug inserted into the second support rod, the second plug is provided with a second countersunk through hole for passing the second bolt, and the upper end of the second support rod is provided with a second connecting hole corresponding to the second countersunk through hole.

[0025] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0026] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "fixed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figure 1 to Figure 7 As shown, an embodiment of the present application discloses an electronic drum stand support rod structure, comprising a first support rod 3 and a second support rod 4 connected to the lower end of a column 2 of the electronic drum stand 1, the upper ends of the first support rod 3 and the second support rod 4 are respectively rotated on both sides of the lower end of the column 2; the first support rod 3 and the second support rod 4 can be opened to a supporting position along a direction of separation from each other in a YZ plane and rotated to a storage position along a direction of approaching each other, and a limiting portion for limiting the supporting position and the storage position is provided between the first support rod 3 and the column 2 and between the second support rod 4 and the column 2.

[0030] For more details, please refer to the attached Figure 1 The lower end of the column 2 is provided with a connecting pipe 5, and the outer wall of the connecting pipe 5 is provided with a symmetrically distributed first joint 6 and a second joint 7, and the upper ends of the first support rod 3 and the second support rod 4 are respectively provided with a third joint 8 rotatably connected to the first joint 6, and a fourth joint 9 rotatably connected to the second joint 7; and the limiting part is provided between the first joint 6 and the third joint, and between the second joint 7 and the fourth joint 9. In the above structure, a fastening bolt and a fastening nut are penetrated on the side wall of the connecting pipe 5, and a connecting through hole for the fastening bolt to pass through is provided at the lower end of the column 2, and the connection and fixation of the column 2 and the connecting pipe 5 are realized by the fastening bolt.

[0031] In this embodiment, see the attached Figure 2The first joint 6 includes a first connecting column 10, a first threaded hole is provided on the first connecting column 10, a first bolt 11 is movably passed through the third joint 8, and the first bolt 11 is connected to the first threaded hole; the second joint 7 includes a second connecting column 12, a second threaded hole is provided on the second connecting column 12, a second bolt 13 is movably passed through the fourth joint 9, and the second bolt 13 is connected to the second threaded hole. In this structure, in order to ensure the stability of the two bolt connection structures, metal nuts are embedded in the first connecting column 10 and the second connecting column 12, that is, the two bolt thread matching parts are essentially two metal nuts, and the metal nuts are pre-embedded injection molded in the corresponding connecting column structure, which fully ensures the strength of the connection structure. In addition, after the first joint 6 and the third joint 8, and the second joint 7 and the fourth joint 9 are fixed by bolt connection, the third joint 8 can still rotate relative to the first joint 6 and the fourth joint 9 can still rotate relative to the second joint 7, so that the two support rods can rotate and realize the switching between opening and storage.

[0032] For more details, please refer to the attached Figures 2 to 6 In this embodiment, the first joint 6 also includes an annular first plug plate 14, the first connecting column 10 is located in the first plug plate 14, and a first limit block 15 is provided on the outer wall of the first connecting column 10, and the third joint 8 includes an annular first slot 16 and a first abutment block 19, the first plug plate 14 can be rotatably fitted in the first slot 16, and when the first support rod 3 is rotated to the first limit position in the clockwise direction, the first abutment surface 20 of the first abutment block 19 abuts against the first limit surface 17 of the first limit block 15, and when the first support rod 3 is rotated to the second limit position in the counterclockwise direction, the second abutment surface 21 of the first abutment block 19 abuts against the second limit surface 18 of the first limit block 15, that is, the first support rod 3 is limited in the supporting position and the storage position.

[0033] Similarly, the second joint 7 also includes an annular second plug plate 22, the second connecting column 12 is located in the second plug plate 22, and a second limit block 23 is provided on the outer wall of the second connecting column 12, the fourth joint 9 includes an annular second slot 24 and a second abutment block 27, the second plug plate 22 can be rotatably fitted in the second slot 24, and when the second support rod 4 is rotated to the first extreme position in the clockwise direction, the third abutment surface 28 of the second abutment block 27 abuts against the third limit surface 25 of the second limit block 23, and when the second support rod 4 is rotated to the second extreme position in the counterclockwise direction, the fourth abutment surface 29 of the second abutment block 27 abuts against the fourth limit surface 26 of the second limit block 23, thereby realizing the limitation of the second support rod 4 in the supporting position and the storage position.

[0034] In the above structure, when in the supporting position, the first support rod 3 and the second support rod 4 are respectively located at the first limit position, and the first support rod 3 and the second support rod 4 form an angle of about 80°. Figure 1 When in the storage position, the first support rod 3 and the second support rod 4 are respectively located at the second extreme position, and the first support rod 3 and the second support rod 4 form an angle of approximately 60°, as shown in the attached Figure 7 shown.

[0035] In addition, see Appendix Figure 5 , 6 It can be seen that in this embodiment, the first limit block 15 and the second limit block 23 are respectively integrally formed on the outer walls of the first connecting column 10 and the second connecting column 12, and the planes where the first limit surface 17 and the second limit surface 18 are located pass through the center of the first connecting column 10; the planes where the third limit surface 25 and the fourth limit surface 26 are located pass through the center of the second connecting column 12, and the angle α between the first limit surface 17 and the second limit surface 18, and between the third limit surface 25 and the fourth limit surface 26 is about 70°.

[0036] Similarly, the first abutment block 19 and the second abutment block 27 are integrally formed and processed at corresponding positions on the third joint 8 and the fourth joint 9, respectively, and see the attached Figure 2 , 3 It can be seen that the first abutment block 19 and the second abutment block 27 are respectively outside the outer end surfaces of the first slot 16 and the second slot 24, so as to facilitate the abutment and cooperation with the limiting surfaces of the corresponding limiting blocks during assembly. The planes where the first abutment surface 20 and the second abutment surface 21 are located, and the planes where the third abutment surface 28 and the fourth abutment surface 29 are located respectively pass through the circles of the first slot 16 and the second slot 24, and the clamping between the first abutment surface 20 and the second abutment surface 21, and the angle β between the third abutment surface 28 and the fourth abutment surface 29 are about 100°. This structural design can not only ensure the structural strength of each limiting block and the abutment block itself, but also ensure the contact area when each limiting block abuts against the abutment block, thereby increasing the limiting stability.

[0037] In the above structure, see the attached Figure 1 and 4, the third joint 8 also includes a first insert tube 30 inserted into the first support rod 3, the first insert tube 30 is provided with a first countersunk through hole for passing the first bolt 11, and the upper end of the first support rod 3 is provided with a first connecting hole corresponding to the first countersunk through hole; similarly, the fourth joint 9 also includes a second insert tube 31 inserted into the second support rod 4, the second insert tube 31 is provided with a second countersunk through hole for passing the second bolt 13, and the upper end of the second support rod 4 is provided with a second connecting hole corresponding to the second countersunk through hole. In this structure, the first bolt 11 not only realizes the connection between the first support rod 3 and the first insert tube 30, but also realizes the rotational connection between the first insert tube 30 and the connecting tube 5; similarly, the second bolt 13 realizes the connection between the second support rod 4 and the second insert tube 31, and also realizes the rotational connection between the second insert tube 31 and the connecting tube 5. This connection method has a simple structure, convenient operation, fewer parts and components, and low cost.

[0038] See the attached Figure 4 The outer walls of the first plug plate 14 and the second plug plate 22 are both conical surfaces, and the inner hole walls of the first slot 16 and the second slot 24 are matched with the conical surfaces. This structure can increase the locking force of the plug-in structure between the first plug tube 30 and the connecting tube 5, and between the second plug tube 31 and the connecting tube 5 when the first bolt 11 and the second bolt 13 are tightened, thereby ensuring that when the first support rod 3 and the second support rod 4 are in the storage position, the first support rod 3 and the second support rod 4 will not rotate and fall down due to the small friction resistance at the rotation connection, thereby affecting the corresponding mobile packaging after the drum rack is stored.

[0039] In some embodiments, a transverse connecting rod 32 is detachably connected to the lower end of the first supporting rod 3, and support pads 33 are arranged at both ends of the transverse connecting rod 32; a support pad 33 is connected to the lower end of the second supporting rod 4, and the support pads 33 at both ends of the transverse connecting rod 32 and the support pad 33 at the lower end of the second supporting rod 4 are basically distributed in a triangular shape, thereby further improving the stability of the supporting structure. For details, see the attached Figure 1 .

[0040] In the description of the present application, the description with reference to the terms "present embodiment", "some embodiments", etc. means that the specific features, mechanisms, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, mechanisms, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradicting each other.
