[0033] The audio rack is used to support audio equipment, such as CD players, power amplifiers, and phono players. It can accurately adjust the height and level of the audio equipment to reduce the interference caused by the unstable level of the audio equipment and the vibration reflection of the ground or the environment. At the same time, it can reduce the vibration of the audio equipment itself and make the sound quality purer. The audio rack generally includes two panels, upper and lower. When installing the height and positioning of the audio equipment, the height of the two panels needs to be adjusted separately, which is inconvenient to adjust.

[0034] In order to solve the above technical problems, the present invention proposes an audio rack bracket, wherein the support assembly 30 is located between the first panel 10 and the second panel 20, and the rotating drive member 33 drives the transmission assembly 34 to rotate, and the transmission assembly 34 is threadedly connected to the base structure 40, so that the transmission assembly 34, the first support structure 31, the second support structure 32, the first panel 10, and the second panel 20 are lifted and lowered synchronously, and there is no need to adjust the heights of the first panel 10 and the second panel 20 separately, so that the adjustment of the audio rack bracket is more convenient.

[0035] The audio rack support provided by the embodiment of the present invention is now described.

[0036] Please also read Figure 1 and Figure 2 The audio rack bracket includes a first panel 10, a second panel 20 arranged below the first panel 10, a supporting assembly 30 supporting the first panel 10 and the second panel 20, and a base structure 40 arranged below the second panel 20. The supporting assembly 30 includes a rotating driving member 33, a transmission assembly 34 driven by the rotating driving member 33, a first supporting structure 31 and a second supporting structure 32. The motion input end of the transmission assembly 34 is fixedly connected to the rotating driving member 33, and the motion output end of the transmission assembly 34 is threadedly connected to the base structure 40. One end of the first supporting structure 31 is fixedly connected to the first panel 10, and one end of the second supporting structure 32 is fixedly connected to the second panel 20.

[0037] The base structure 40 is a structure at the bottom end of the sound rack support, and is generally placed on the ground so that there is a certain distance between the second panel 20 and the ground.

[0038] The first panel 10 and the second panel 20 are both arranged horizontally, and the second panel 20 is located below the first panel 10. When the sound rack bracket is placed on the ground, the second panel 20 is arranged closer to the ground, and the first panel 10 is used to place the speaker to increase the placement height of the speaker.

[0039] The support assembly 30 is located between the first panel 10 and the second panel 20, and the support assembly 30 can be arranged vertically. The support assembly 30 includes a rotary drive member 33, a transmission assembly 34, a first support structure 31 and a second support structure 32. One end (upper end) of the first support structure 31 is fixedly connected to the first panel 10, and one end (lower end) of the second support structure 32 is fixedly connected to the second panel 20. The first support structure 31 is located above the second support structure 32, and the lower end of the first support structure 31 and the upper end of the second support structure 32 are close to each other. The rotary drive member 33 is a power input structure, and the rotary drive member 33 can be rotated by manual or electric driving. The rotary drive member 33 drives the transmission assembly 34 to move, and the motion output end of the transmission assembly 34 also outputs a rotary motion. Since the motion output end of the transmission assembly 34 is threadedly connected to the base structure 40, when the motion output end rotates, it moves up and down at the same time, driving the entire support assembly 30, the first panel 10 and the second panel 20 to move up and down. The first panel 10 and the second panel 20 move synchronously, and there is no need to adjust the height of the first panel 10 and the second panel 20 respectively.

[0040] The audio rack bracket in the above embodiment includes a first panel 10, a second panel 20, a support assembly 30 and a base structure 40. The support assembly 30 is located between the first panel 10 and the second panel 20. In the support assembly 30, the rotation of the rotating drive member 33 drives the transmission assembly 34 to rotate, and the motion output end of the transmission assembly 34 is threadedly connected to the base structure 40, so that the transmission assembly 34 drives the first panel 10, the second panel 20, the first support structure 31 and the second support structure 32 to move up and down as a whole. There is no need to adjust the height of the first panel 10 and the second panel 20 separately, and there is no need to bend down to adjust the height, so the height adjustment is more convenient.

[0041] In some embodiments of the present invention, see Figure 2 , the first support structure 31 is fixedly connected at one end away from the first panel 10, and the second support structure 32 is fixedly connected at one end away from the second panel 20. The end of the first support structure 31 away from the first panel 10 is the lower end of the first support structure 31, and the end of the second support structure 32 away from the second panel 20 is the upper end of the second support structure 32, that is, the lower end of the first support structure 31 and the upper end of the second support structure 32 are fixedly connected.

[0042] When the speaker is placed on the first panel 10, the gravity of the speaker is transmitted to the base structure 40 through the first panel 10, the first supporting structure 31, the second supporting structure 32 and the second panel 20 in sequence. Therefore, the rotating drive member 33 and the transmission assembly 34 (except the motion output end) are not subjected to the gravity of the speaker, the first panel 10, the first supporting structure 31 and the second supporting structure 32. Therefore, it is very easy to drive. When the rotating drive member 33 is manually rotated, it is very labor-saving and the rotation is smooth and not easy to get stuck.

[0043] In some embodiments, see Figures 7 to 9 The motion output end of the transmission assembly 34 is the second rotating rod 345, which is threadedly connected to the base structure 40 and the second support structure 32. The second rotating rod 345 is fixedly connected to other parts of the transmission assembly 34 (which can be called the transmission body) in the circumferential direction and is movably arranged in the axial direction. The axial direction is the central axis direction of the second rotating rod 345, and the circumferential direction is the direction around the axial direction.

[0044] When the speaker is placed on the first panel 10, the gravity of the speaker is transmitted to the base structure 40 through the first panel 10, the first support structure 31, the second support structure 32, the second rotation rod 345 and the second panel 20 in sequence. Therefore, the rotating drive member 33 and the transmission assembly 34 (except the second rotation rod 345) do not bear the gravity of the speaker, the first panel 10, the first support structure 31 and the second support structure 32. Therefore, it is easy to drive. When manually rotating the rotating drive member 33, it is very labor-saving, and the rotation is smooth and not easy to get stuck. Figure 2 The load-bearing structure is Figure 2 The medium grey parts (shaded parts), the transmission assembly 34 (except the second rotating rod 345 ) does not bear gravity, and the driving force required to rotate the driving member 33 is relatively large, and only needs to overcome the internal resistance of the transmission assembly 34 .

[0045] Optionally, one of the transmission body and the second rotating rod 345 has a transmission hole 3451, and the other has a transmission part 3441, and the transmission part 3441 is inserted into the transmission hole 3451 along the axial direction, so that the transmission body and the second rotating rod 345 are fixedly connected in the circumferential direction and movably arranged in the axial direction. The cross-section of the transmission hole 3451 and the transmission part 3441 is a non-rotating structure, which can be a square, D-shaped, hexagonal, etc.

[0046] In some embodiments, see Figure 2 , Figure 6 and Figure 8 The first supporting structure 31 includes a first supporting column 311 and a first connecting frame 312 fixedly connected to each other, and one end of the first supporting column 311 is fixedly connected to the first panel 10; the second supporting structure 32 includes a second supporting column 321 and a second connecting frame 322 fixedly connected to each other, and one end of the second supporting column 321 is fixedly connected to the second panel 20; the first supporting column 311, the rotating driving member 33 and the second supporting column 321 form a accommodating space, the transmission assembly 34, the first connecting frame 312 and the second connecting frame 322 are both located in the accommodating space, and the first connecting frame 312 and the second connecting frame 322 are fixedly connected.

[0047] In the first support structure 31, the first support column 311 is at least partially exposed, the upper end of the exposed part of the first support column 311 is connected to the first panel 10, the lower end of the exposed part of the first support column 311 extends to the upper end of the rotary drive member 33, and the first connecting frame 312 is at least partially located in the accommodation space. In the second support structure 32, the second support column 321 is at least partially exposed, the upper end of the exposed part of the second support column 321 extends to the lower end of the rotary drive member 33, the lower end of the exposed part of the second support column 321 is connected to the second panel 20, and the second connecting frame 322 is at least partially located in the accommodation space. The connection between the first connecting frame 312 and the second connecting frame 322 is located in the accommodation space. Among them, the exposed part of the first support column 311, the exposed part of the rotary drive member 33 and the exposed part of the second support column 321 form the outer shell structure of the support assembly 30, and the internal space surrounded by the outer shell structure is the accommodation space.

[0048] By setting the first support structure 31 as the first support column 311 and the first connecting frame 312, and setting the second support structure 32 as the second support column 321 and the second connecting frame 322, the first support structure 31 and the second support structure 32 can not only become the outer shell structure of the support component 30, but also be connected to each other inside the accommodating space to form a complete gravity support chain. Secondly, it is convenient to process the first support structure 31 and the second support structure 32 and install the transmission component 34, etc.

[0049] In some embodiments of the present invention, see Figures 3 to 5 The transmission assembly 34 includes a first bevel gear 341, two second bevel gears 342 that are meshed with the first bevel gear 341, a third bevel gear 343 that is meshed with the two second bevel gears 342, a first rotating rod 344 and a second rotating rod 345. The rotating drive member 33 extends to be fixedly connected to the first bevel gear 341, the third bevel gear 343 is fixedly connected to the first rotating rod 344, the first rotating rod 344 and the second rotating rod 345 are circumferentially fixedly arranged, the second rotating rod 345 is threadedly connected to the base structure 40, and the second rotating rod 345 is threadedly connected to the second support structure 32.

[0050] When the rotary drive member 33 rotates, the first bevel gear 341 rotates, and the rotation of the first bevel gear 341 drives the two second bevel gears 342 to rotate, and the rotation of the two second bevel gears 342 drives the first rotating rod 344 to rotate, and the rotation of the first rotating rod 344 drives the second rotating rod 345 to rotate, and the rotation of the second rotating rod 345 drives the second supporting structure 32 to move up and down, thereby driving the entire supporting assembly 30 and the first panel 10 and the second panel 20 to move up and down. Since the first rotating rod 344 and the second rotating rod 345 are fixedly arranged in the circumferential direction, and the first rotating rod 344 and the second rotating rod 345 are axially movable, when the speaker is placed on the first panel 10, the gravity of the speaker and each component can be transmitted to the second rotating rod 345 through the second supporting structure 32, but will not be transmitted to the first rotating rod 344, so that the driving force required for the rotary drive member 33 when rotating is small, and the rotation is smoother. Among them, the motion input end of the transmission assembly 34 is the first bevel gear 341, and the motion output end of the transmission assembly 34 is the second rotating rod 345.

[0051] The position of the rotating shaft 346 at the motion output end of the transmission assembly 34 can be changed by setting the bevel gear, so that the transmission assembly 34 can be set inside the accommodating space. Moreover, the second rotating rod 345 is threadedly connected to the base structure 40 and the second supporting structure 32 at the same time. When the second rotating rod 345 rotates, the second rotating rod 345 rotates and moves up and down at the same time. The second supporting structure 32 can only move up and down under the restriction of the second panel 20. The second rotating rod 345 transmits the gravity of each component (sound box, first supporting structure 31, second supporting structure 32, first panel 10, second panel 20, etc.) to the base structure 40, and also promotes the second supporting structure 32 to move up and down, so as to realize the lifting and lowering movement of the first panel 10 and the second panel 20.

[0052] In some embodiments, the central axis of the first bevel gear 341 and the central axis of the third bevel gear 343 are both arranged vertically, and the central axes of the two second bevel gears 342 are both arranged horizontally, and the first bevel gear 341 rotates synchronously with the rotary drive member 33, and the two second bevel gears 342 rotate synchronously. The first bevel gear 341, the second bevel gear 342, and the third bevel gear 343 are all arranged in the accommodation space. Through the arrangement of each bevel gear, the rotational motion of the rotary drive member 33 is transmitted to the rotation of the first rotating rod 344 located in the accommodation space, and the transmission assembly 34 can be transferred to the interior of the support assembly 30, so that the appearance of the support assembly 30 is more complete and the product texture is better.

[0053] In some embodiments, the rotary drive member 33 is fixedly connected to the first bevel gear 341 via a sixth locking member, and the rotary drive member 33 can be connected to the back of the first bevel gear 341 , where the back of the first bevel gear 341 is the side without teeth.

[0054] In some embodiments, the third bevel gear 343 and the first rotating rod 344 are fixedly connected by a fastener, and the fastener can pass through the center of the third bevel gear 343 and be connected to the upper end of the first rotating rod 344 to fix the third bevel gear 343 and the first rotating rod 344.

[0055] In some embodiments, see Figure 3 and Figure 4 , the first rotating rod 344 and the second rotating rod 345 are circumferentially fixedly connected by means of the transmission hole 3451. Specifically, one of the first rotating rod 344 and the second rotating rod 345 has a transmission hole 3451, and the other has a transmission part 3441, and the transmission part 3441 is inserted into the transmission hole 3451, so that the rotation of the first rotating rod 344 can drive the rotation of the second rotating rod 345, and no axial force is generated on the second rotating rod 345. The cross-sections of the transmission hole 3451 and the transmission part 3441 can be rectangular, D-shaped, hexagonal, etc.

[0056] Optionally, at least one end of the first rotating rod 344 close to the second rotating rod 345 has a transmission part 3441, and at least one end of the second rotating rod 345 close to the first rotating rod 344 has a transmission hole 3451. For example, the bottom end of the first rotating rod 344 is a square rod, and the top end of the second rotating rod 345 has a square hole.

[0057] Optionally, at least one end of the first rotating rod 344 close to the second rotating rod 345 has a transmission hole 3451, and at least one end of the second rotating rod 345 close to the first rotating rod 344 has a transmission part 3441. For example, the bottom end of the first rotating rod 344 has a square hole, and the top end of the second rotating rod 345 has a square shaft.

[0058] In some embodiments of the present invention, see Figures 5 to 9 The first supporting structure 31 includes a first supporting column 311 and a first connecting frame 312, one end of the first supporting column 311 is fixedly connected to the first panel 10, the other end of the first supporting column 311 is close to the rotating driving member 33, one end of the first connecting frame 312 is connected to the first supporting column 311, and the other end of the first connecting frame 312 extends to the second bevel gear 342;

[0059] The second support structure 32 includes a second support column 321 and a second connecting frame 322, one end of the second support column 321 is fixedly connected to the second panel 20, one end of the second support column 321 extends to the rotation driving member 33, one end of the second connecting frame 322 is connected to the second support column 321, and the other end of the second connecting frame 322 extends to the second bevel gear 342 and is fixedly connected to the first connecting frame 312;

[0060] The first support column 311, the rotary drive member 33 and the second support column 321 are arranged in sequence from top to bottom and surround a receiving space, and the transmission assembly 34, the first connecting frame 312 and the second connecting frame 322 are all located in the receiving space.

[0061] In the first support structure 31, at least part of the first support column 311 is exposed, and the first connecting frame 312 is located inside the accommodation space. In the second support structure 32, at least part of the second support column 321 is exposed, and the second connecting frame 322 is located inside the accommodation space. The first connecting frame 312 and the second connecting frame 322 are fixedly connected at the bevel gear. The exposed part of the first support column 311, the exposed part of the rotary drive member 33, and the exposed part of the second support column 321 constitute the outer shell structure of the support assembly 30, and the inner space of the outer shell structure is the accommodation space of the support assembly 30.

[0062] By setting the first support structure 31 as the first support column 311 and the first connecting frame 312, and setting the second support structure 32 as the second support column 321 and the second connecting frame 322, firstly, the first support structure 31 and the second support structure 32 can become the outer shell structure of the support assembly 30, and can be connected to each other inside the accommodating space to form a complete gravity support chain, and secondly, it is convenient to process the first support structure 31 and the second support structure 32 and install the transmission assembly 34, etc. In addition, there are many structures at the first bevel gear 341, the second bevel gear 342 and the third bevel gear 343, and setting the connection between the first connecting frame 312 and the second connecting frame 322 at the bevel gear makes it more convenient to install each bevel gear.

[0063] In some embodiments, see Figure 2 The first support column 311 and the second support column 321 are both hollow structures, so that the internal spaces of the first support column 311 and the second support column 321 can be utilized.

[0064] In some embodiments, see Figure 2 The upper end of the first support column 311 is fixedly connected to the first panel 10 through the first locking member 51, and the first locking member 51 passes through the second panel 20 and is threadedly connected to the upper end of the first support column 311. For example, the upper end of the first support column 311 has an internal thread, and the first locking member 51 can be a rivet, a screw, etc.

[0065] In some embodiments, see Figure 2 and Figure 6 The lower end of the first support column 311 is locked with the first connecting frame 312 through the second locking piece 52. The lower end of the first support column 311 has a supporting end wall 3111. The first connecting frame 312 is arranged through the supporting end wall 3111. The second locking piece 52 is locked with one end of the first connecting frame 312 passing through the supporting end wall 3111, thereby pressing and fixing the first support column 311 and the first connecting frame 312.

[0066] Optionally, the first connecting frame 312 is threadedly connected to the supporting end wall 3111 .

[0067] Optionally, the first connecting frame 312 is threadedly connected to the second locking member 52, and the second locking member 52 may be a nut.

[0068] In some embodiments of the present invention, see Figure 5 and Figure 6The first connecting frame 312 includes a connecting shaft 3122 and a first fixed portion 3123 radially extending outward from the connecting shaft 3122, and the connecting shaft 3122 is arranged through the center of the first bevel gear 341; the second connecting frame 322 includes a wrapping portion 3221 located at the outer periphery of the third bevel gear 343, a second fixed portion 3223 fixedly connected to the second support column 321, and a connecting neck 3222 connecting the wrapping portion 3221 and the second fixed portion 3223, and a rotating bearing 347 is arranged between the connecting neck 3222 and the first rotating rod 344; the first fixing portion 3123 is fixedly connected to the wrapping portion 3221.

[0069] The connecting shaft 3122 is located above the first fixed portion 3123, and the connecting shaft 3122 is arranged through the center of the first bevel gear 341. It can be understood that the first bevel gear 341 is rotatably arranged on the connecting shaft 3122, and the connecting shaft 3122 is fixed. A bearing can be arranged between the connecting shaft 3122 and the first bevel gear 341. The radial direction of the connecting shaft 3122 is the direction perpendicular to the length direction of the connecting shaft 3122. The outer profile size of the first fixed portion 3123 is larger than the outer diameter of the connecting shaft 3122, which facilitates the connection and fixation of the first fixed portion 3123 and the wrapping portion 3221. In the second connecting frame 322, the wrapping portion 3221 is wrapped around the outer periphery of the third bevel gear 343, which means that the wrapping portion 3221 is wrapped around the back of the third bevel gear 343, and does not affect the tooth meshing of the front of the third bevel gear 343. The outer diameter of the connecting neck 3222 may be smaller than the outer diameters of the wrapping portion 3221 and the second fixing portion 3223 , so as to facilitate the arrangement of the rotating bearing 347 between the connecting neck 3222 and the first rotating rod 344 .

[0070] By arranging the connecting shaft 3122 on the first connecting frame 312, it is convenient to install the first bevel gear 341, and by arranging the connecting neck 3222 on the second connecting frame 322, it is convenient to position the first rotating rod 344 in the circumferential direction to prevent the first rotating rod 344 from shaking.

[0071] In some embodiments, see Figure 6 The first connecting frame 312 further includes a connecting threaded column 3121, which is used for threaded connection with the supporting end wall 3111 and for threaded connection with the second locking member 52. The threaded column 3121, the connecting shaft 3122 and the first fixing portion 3123 are arranged in sequence from top to bottom.

[0072] In some embodiments, the first fixing portion 3123 and the wrapping portion 3221 are connected and fixed by a third locking member. The third locking member may be a threaded member that passes through the first fixing portion 3123 and is threadedly connected and fixed to the wrapping portion 3221.

[0073] In some embodiments of the present invention, see Figures 6 to 8The second support column 321 includes an outer support portion 3211 and an inner support portion 3212 that are interconnected. The outer support portion 3211 is fixedly connected to the second panel 20 at one end away from the inner support portion 3212, and the inner support portion 3212 is fixedly connected to the second fixed portion 3223 at one end away from the outer support portion 3211. The inner support portion 3212 is located between the rotating drive member 33 and the second rotating rod 345. A step structure is formed at the connection between the outer support portion 3211 and the inner support portion 3212, and one end of the rotating drive member 33 is located at the step structure.

[0074] The outer support part 3211 is exposed, the inner support part 3212 is located in the accommodation space, and the first support column 311, the rotation drive member 33 and the outer support part 3211 are all exposed. A step structure is formed between the outer support part 3211 and the inner support part 3212, and the outer diameter of the outer support part 3211 is larger than the outer diameter of the inner support part 3212. In this way, the rotation drive member 33 and the outer support part 3211 can be flush, so that the appearance of the support assembly 30 is relatively flat. It should be noted that, since the support assembly 30 is supported as a whole by the first support structure 31 and the second support structure 32, there is no abutment force between the outer support portion 3211 and the lower end of the rotating drive member 33, the outer support portion 3211 and the lower end of the rotating drive member 33 only contact each other or are spaced apart, there is no abutment force between the first support column 311 and the upper end of the rotating drive member 33, the first support column 311 and the upper end of the rotating drive member 33 only contact each other or are spaced apart, and the first support column 311 and the upper end of the rotating drive member 33 only contact each other or are spaced apart.

[0075] By configuring the second support column 321 to include an outer support portion 3211 and an inner support portion 3212 , the second support column 321 is more easily fixedly connected to the second connecting frame 322 .

[0076] In some embodiments, the second fixing portion 3223 of the second rotating frame and the upper ends of the inner support portion 3212 both have L-shaped steps, and the two L-shaped steps cooperate with each other to achieve radial positioning and axial positioning of the second fixing portion 3223 and the inner support portion 3212, and enable the outer sides of the second fixing portion 3223 and the inner support portion 3212 to be flush with each other.

[0077] In some embodiments of the present invention, see Figures 7 to 9The support assembly 30 also includes a bottom sleeve 348 that passes through the second panel 20, and a rotating screw 41 is threadedly connected to the base structure 40. The bottom sleeve 348, the second panel 20 and the second support structure 32 are fixedly connected, and part of the second support structure 32, the bottom sleeve 348, the second rotating rod 345, and the rotating screw 41 are arranged in sequence from the outside to the inside; the bottom sleeve 348 has a first internal thread, the second rotating rod 345 has a first external thread that matches the first internal thread, the second rotating rod 345 also has a second internal thread, and the rotating screw 41 has a second external thread that matches the second internal thread; the pitch of the first internal thread and the first external thread is a first value, the pitch of the second internal thread and the second external thread is a second value, and the first value and the second value are not equal.

[0078] The second support structure 32 includes a second support column 321, the bottom end of which is in contact with the second panel 20, and a bottom sleeve 348 is arranged through the second panel 20, that is, the bottom sleeve 348 is located inside the second support column 321. The bottom sleeve 348, the second panel 20 and the second support column 321 are fixedly connected to form a whole, and move up and down synchronously. The second rotating rod 345 is a hollow structure, and the second rotating rod 345 has both internal threads and external threads, which are threadedly connected with the rotating screw 41 and the bottom sleeve 348 respectively, and the bottom sleeve 348 and the second panel 20 are driven to move up and down together by the rotation of the second rotating rod 345. At the same time, the pitch of the first internal thread and the pitch of the second internal thread are not equal, so that when the second rotating rod 345 rotates one circle, the distance of the bottom sleeve 348 rising or falling is the absolute value A of the difference between the second value and the first value. By designing A, the fineness of the height or level adjustment of the first panel 10 and the second panel 20 can be changed.

[0079] By setting the bottom sleeve 348, the second support column 321 is fixedly connected to the second panel 20, and an internal thread that cooperates with the second rotating rod 345 can be formed on the inner wall of the bottom sleeve 348; by respectively setting the first external thread and the second internal thread on the outer wall and the inner wall of the second rotating rod 345, the pitch of the first external thread and the second internal thread are different, thereby changing the adjustment accuracy of the height or level of the first panel 10 and the second panel 20.

[0080] In some embodiments, when the first value is less than the second value, when the rotary drive member 33 is rotated in the first direction, the second panel 20 rises, and when the rotary drive member 33 is rotated in the second direction, the second panel 20 falls. When the first value is greater than the second value, when the rotary drive member 33 is rotated in the first direction, the second panel 20 falls, and when the rotary drive member 33 is rotated in the second direction, the second panel 20 rises. The first direction is clockwise, and the second direction is counterclockwise; or, the first direction is counterclockwise, and the second direction is clockwise.

[0081] In some embodiments, the absolute value of the difference between the second value and the first value is smaller than the first value and the second value, so that the height or level of the first panel 10 and the second panel 20 can be fine-tuned to make the adjustment more precise. For example, the first value is 2.5 mm, the second value is 3 mm, and the second rotating rod 345 rotates one circle, and the height of the first panel 10 and the second panel 20 at the support assembly 30 increases or decreases by 0.5 mm.

[0082] In some embodiments, the outer side of the bottom sleeve 348 extends radially outward to form a connecting ear 3481, which abuts against the bottom end of the second support column 321. A fourth locking member passes through the connecting ear 3481 and is connected to the second support column 321, thereby fixing the bottom sleeve 348 and the second support column 321 in connection.

[0083] In some embodiments, the second support column 321 and the second panel 20 may be fixedly connected via a locking member, or the second support column 321 may be placed in a corresponding groove of the second panel 20 .

[0084] In some embodiments of the present invention, see Figure 3 and Figure 4 The rotary driving member 33 includes a rotating cylinder 331 that is exposed and an extending portion 332 that is formed by radially extending inward from the upper end of the rotating cylinder 331 , and the extending portion 332 covers and fixes the back of the first bevel gear 341 .

[0085] The rotating cylinder 331 is exposed and is a part of the outer shell of the support assembly 30. The outer surface of the first support column 311, the outer surface of the rotating cylinder 331 and the outer surface of the outer support portion 3211 constitute the outer surface of the support assembly 30. The extension portion 332 is located inside the accommodating space and is fixedly connected to the first bevel gear 341. The back of the first bevel gear 341 is the side of the first bevel gear 341 without meshing teeth.

[0086] The extended portion 332 is provided to achieve a fixed connection between the rotary drive member 33 and the first bevel gear 341. Moreover, the extended portion 332 covers and is fixed to the back of the first bevel gear 341, and does not affect the meshing of the first bevel gear 341.

[0087] In some embodiments, the extension portion 332 is configured to conform to the back of the first bevel gear 341 , so that the positioning and matching between the extension portion 332 and the first bevel gear 341 is better, and the shaking between the extension portion 332 and the first bevel gear 341 is reduced.

[0088] In some embodiments, an anti-slip portion 3311 is fixed to the outer periphery of the rotating cylinder 331 to increase the friction between the rotating drive member 33 and the hand, making the rotation more labor-saving.

[0089] Optionally, the anti-slip portion 3311 may be a pattern structure, a convex and concave structure, etc.

[0090] Optionally, the anti-slip portion 3311 may be adhered and fixed to the outer circumference of the rotating cylinder 331 , or the anti-slip portion 3311 and the rotating cylinder 331 may be integrally formed.

[0091] In some embodiments, a bearing is disposed between the outer circumferential wall of the extension portion 332 and the inner circumferential wall of the first support column 311 , so that the rotation of the rotary drive member 33 is smoother and the required driving force is smaller.

[0092] In some embodiments, see Figure 4 The extension part 332 and the first bevel gear 341 are locked and fixed by a sixth locking member, and the sixth locking member passes through the extension part 332 and is connected to the back of the first bevel gear 341. The sixth locking member can be a screw or the like.

[0093] In some embodiments of the present invention, see Figure 5 and Figure 6 The transmission assembly 34 also includes a rotating shaft 346 , and the two second bevel gears 342 are symmetrically rotatably arranged on the rotating shaft 346 . The first connecting frame 312 is provided with an axial hole for the rotating shaft 346 to pass through, and the rotating shaft 346 is fixedly connected to the first connecting frame 312 .

[0094] The two second bevel gears 342 rotate synchronously and are supported by the rotating shaft 346 . The rotating shaft 346 is fixedly connected to the first connecting frame 312 . Therefore, the second bevel gears 342 are supported by the first supporting structure 31 .

[0095] In some embodiments, the rotating shaft 346 and the first connecting frame 312 are fixedly connected by a fifth locking member 55. The fifth locking member 55 passes through the bottom of the first connecting frame 312, the rotating shaft 346, and is locked and fixed with another part of the first connecting frame 312.

[0096] In some embodiments, the first connecting frame 312 has a first fixing portion 3123 , an axial hole is disposed in the first fixing portion 3123 , and the rotating shaft 346 is disposed through the first fixing portion 3123 , and the rotating shaft 346 does not interfere with the first connecting frame 312 .

[0097] In some embodiments of the present invention, see Figure 1 , the number of the supporting assemblies 30 is multiple, and the multiple supporting assemblies 30 are arranged between the first panel 10 and the second panel 20. The arrangement of multiple supporting assemblies 30 can make the overall structure of the audio rack bracket more stable, and at the same time, the horizontality of the first panel 10 and the second panel 20 can be adjusted by adjusting each supporting assembly 30 respectively. For example, the number of supporting assemblies 30 is four, and they are respectively arranged at the four corners of the first panel 10.

[0098] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
