Description

Technical Field

[0001] This invention relates to the technical field of speaker support devices, and more specifically to a speaker bracket assembly. Background Technology

[0002] A speaker support tripod is a triangular structure used to fix and support speaker equipment. These tripods are typically made of metal or plastic and have sufficient stability and load-bearing capacity to ensure that the speaker equipment will not wobble or tilt during prolonged use.

[0003] Existing speaker stands have gaps between their support rods and the speaker trays. Conventional speaker stand support rods are straight tubes with an outer diameter of 35mm. To ensure proper installation, the matching speaker trays have an inner diameter greater than 35mm. This results in gaps when the speaker support rods and trays fit together. These gaps can easily cause the speaker to wobble and become unstable. Furthermore, when the speaker is playing music, its low frequencies can cause resonance between the speaker and the speaker stand, affecting sound quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where there is a gap when the speaker support rod and the tray are fitted together, which causes the speaker to wobble and become unstable.

[0005] To address the aforementioned problems, this invention provides an audio speaker bracket assembly, comprising a support rod, a base, and multiple tensioning blocks. The support rod has an axially oriented inner hole, and its outer peripheral wall has multiple circumferentially distributed tensioning holes, all extending into the inner hole. Each tensioning block is located within the inner hole and corresponds to one of the tensioning holes. A limiting structure within the inner hole guides the tensioning blocks to move radially along the support rod. The base is slidably inserted into the inner hole from one end of the support rod. The base has multiple circumferentially distributed and obliquely arranged guide blocks. Each tensioning block has an obliquely arranged guide rail on its side facing the base. The guide blocks and guide rails correspond to each other and are slidably connected. When the base slides axially, the guide blocks, guided by the guide rails, cause the tensioning blocks to extend / retract from the outer peripheral wall of the support rod along the tensioning holes.

[0006] Compared with existing technologies, the above solution controls the tension block to extend / retract from the outer peripheral wall of the support rod by moving the base, thereby achieving adjustment of the overall outer diameter of the support rod. In other words, the tension block compensates for the assembly gap between the support rod and the speaker tray, effectively improving the support rod's stability for the speaker and ensuring that the speaker's sound quality is not affected. At the same time, the tension block and the base achieve a sliding fit through guide rails and guide blocks. By adjusting the movement direction of the base, the extension or retraction of the tension block from the outer peripheral wall of the support rod can be controlled. The adjustment is simple and convenient, with good operability. Furthermore, the tension block's movement direction is restricted by a limiting mechanism, making it less prone to skewing and ensuring structural reliability.

[0007] Preferably, the limiting structure includes a limiting plate fixedly installed in the inner hole. The limiting plate has a plurality of first sliding joints distributed circumferentially, and the first sliding joints are arranged radially along the inner hole. The tensioning block has a second sliding joint, and the second sliding joints are slidably fitted to the corresponding first sliding joints one by one, so that the tensioning block moves only radially along the support rod.

[0008] Preferably, the first sliding joint is a through groove extending along the thickness direction of the limiting plate. The through grooves are distributed circumferentially along the limiting plate and are arranged radially along the inner hole. The tensioning block is slidably engaged in the corresponding through groove. A second sliding joint is provided on each of the opposite sides of the tensioning block. The second sliding joint is a clamping groove parallel to the direction of the through groove. The two clamping grooves of the tensioning block are slidably engaged with the two groove walls of the corresponding through groove. This allows the tensioning block to slide along the through groove and move radially relative to the support rod. On the other hand, since the clamping grooves on both sides of the tensioning block are slidably engaged with the groove walls of the corresponding through groove, the tensioning block is prevented from axially displacing relative to the support rod, ensuring stable operation.

[0009] Preferably, the guide rail is a dovetail groove, and the cross-sectional shape of the guide block is the same as that of the guide rail, thereby achieving a stable sliding connection between the guide rail and the guide block.

[0010] Preferably, the tensioning holes are three in number and evenly distributed along the circumference of the support rod, thereby forming a stable three-point support structure for the speaker tray, resulting in better stability.

[0011] Preferably, the above solution also includes a control structure. The support rod is provided with an external thread. The control structure includes a threaded sleeve that is threaded to the external thread of the support rod, several guide holes located on the outer peripheral wall of the support rod and extending into the inner hole, and a connecting pin located in the guide holes and movable along the axial direction of the support rod. The inner peripheral wall of the threaded sleeve is provided with an annular groove. The connecting pin includes a first end connected to the base and a second end that passes through the guide hole and is slidably inserted into the annular groove. When the threaded sleeve rotates, the annular groove drives the connecting pin and the base to move along the axial direction of the support rod, so that the user can control the axial movement distance of the base by rotating the threaded sleeve. This is not only simple and convenient to adjust, but also has good accuracy.

[0012] Preferably, the guide hole is an elongated hole with its long side parallel to the axial direction of the support rod. The connecting pin slides against the wall of the long side of the guide hole, thereby enabling the wall of the long side of the guide hole to support the connecting pin and allowing the connecting pin to move more stably along the axial direction of the support rod.

[0013] Preferably, there are two guide holes that are symmetrically distributed relative to the axis of the support rod, and the connecting pins are set one by one with the guide holes, so that the annular groove of the threaded sleeve can drive the base to move more smoothly through the two connecting pins.

[0014] Preferably, the base has a tube hole inside, and an elastic element is provided inside the tube hole. The outer peripheral wall of the base has two assembly holes that extend to the tube hole. The assembly holes and guide holes are arranged one by one. The first end of the connecting pin is slidably inserted into the corresponding assembly hole. The two ends of the elastic element are respectively connected to the first ends of the two connecting pins and apply an outward thrust to the two connecting pins, thereby ensuring the sliding insertion of the second end of the connecting pin into the annular groove while making the assembly more convenient.

[0015] Preferably, the support rod is fitted with a threaded sleeve on its outer side, the thread of which is used for screwing into the sleeve. The sleeve and the support rod are detachably connected, which facilitates replacement and maintenance.

[0016] Preferably, the above solution also includes a cap and mounting bolts. The limiting plate is disposed at the end of the inner hole away from the base. The limiting plate is provided with mounting screw holes. One end of the mounting bolt is connected to the mounting screw holes and the other end is connected to the cap, so as to achieve the sealing of the end of the inner hole away from the base by the cap. The cap helps to protect the inner hole and prevent impurities from entering the inner hole. Attached Figure Description

[0026] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should also be noted that all directional indications (such as up, down, left, right, front, back, inside, outside) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] Please see Figures 1-7 An embodiment of the present invention provides an audio bracket assembly, including a support rod 1, a base 3, and a plurality of tensioning blocks 2. The support rod 1 has an axially oriented inner hole 11, and the outer peripheral wall of the support rod 1 has a plurality of circumferentially distributed tensioning holes 12 that all extend into the inner hole 11. The tensioning blocks 2 are located in the inner hole 11 and are arranged correspondingly to the tensioning holes 12. The inner hole 11 has a limiting structure for guiding the tensioning blocks 2 to move radially along the support rod 1. The base 3 is slidably inserted into the inner hole 11 from one end of the support rod 1. The base 3 has a plurality of circumferentially distributed and obliquely arranged guide blocks 31. The side of the tensioning block 2 facing the base 3 has an obliquely arranged guide rail 21. The guide blocks 31 and the guide rails 21 correspond to each other and are slidably connected. When the base 3 slides back and forth axially, the guide blocks 31, guided by the guide rails, drive the tensioning blocks 2 to extend / retract from the outer peripheral wall of the support rod 1 along the tensioning holes 12.

[0028] The above solution controls the tension block 2 to extend / retract from the outer peripheral wall of the support rod 1 by moving the base 3, thereby adjusting the overall outer diameter of the support rod 1. In other words, the tension block 2 compensates for the assembly gap between the support rod 1 and the speaker tray 10, thus effectively improving the support stability of the support rod 1 for the speaker and ensuring that the sound quality of the speaker is not affected. At the same time, the tension block 2 and the base 3 are slidably engaged by the guide rail 21 and the guide block 31. By adjusting the moving direction of the base 3, the tension block 2 can be controlled to extend or retract from the outer peripheral wall of the support rod 1. The adjustment is simple and convenient, and the operation is good. In addition, the tension block 2 is restricted in the moving direction by the limiting mechanism, which makes it less prone to deflection and the structure is reliable.

[0029] For better illustration, in this embodiment, the axis of the support rod 1 is arranged vertically, and the upper end of the support rod 1 is used for mounting the speaker tray 10. The base 3 slides upward from the lower end of the support rod 1 and is inserted into the inner hole 11. The tensioning holes 12 are distributed circumferentially on the outer peripheral wall of the upper part of the support rod 1. In this embodiment, the cross-section of the guide rail 21 is dovetail-shaped, and the cross-sectional shape of the guide block 31 is consistent with that of the guide rail 21, thereby ensuring a stable sliding fit between the two. Of course, the guide rail 21 can also be other structures in the prior art, such as the guide rail 21 being a circular optical axis, and the guide block 31 having a sliding hole that is slidably connected to the circular optical axis. The specific connection form of the guide rail 21 and the guide block 31 is not limited in this design. The guide block 31 on the base 3 gradually tilts outward from top to bottom, and the guide rail 21 on the tension block 2 gradually tilts outward from top to bottom. Thus, when the base 3 moves upward, the guide rail 21 will be pushed outward by the guide block 31; when the base 3 moves downward, the guide rail 21 will be pulled inward by the guide block 31.

[0030] In this embodiment, the limiting structure includes a limiting plate 4 fixedly installed in the inner hole 11. The limiting plate 4 has multiple first sliding parts 41 distributed circumferentially, and the first sliding parts 41 are arranged radially along the inner hole 11. The tensioning block 2 has second sliding parts 22, and the second sliding parts 22 are slidably engaged with the corresponding first sliding parts 41 so that the tensioning block 2 moves only radially along the support rod 1. More specifically, the limiting plate 4 is fixed laterally at the upper end of the inner hole 11. The first sliding part 41 is a through groove that penetrates along the thickness direction of the limiting plate 4, that is, the through groove penetrates the limiting plate 4 vertically. The through grooves are distributed circumferentially along the limiting plate 4 and are arranged radially along the inner hole 11, and the long side of the through groove is parallel to the radial direction of the inner hole 11. The upper end of the tensioning block 2 is slidably engaged in the corresponding through groove. The upper end of the tensioning block 2 has second sliding parts 22 on both opposite sides. The second sliding parts 22 are clamping grooves parallel to the direction of the through groove. The two clamping slots of the tensioning block 2 are respectively slidably engaged with the two groove walls of the corresponding through grooves. This allows the tensioning block 2 to slide along the through grooves and move radially relative to the support rod 1. On the other hand, since the clamping slots on both sides of the tensioning block 2 are respectively slidably engaged with the groove walls of the corresponding through grooves, the tensioning block 2 is prevented from axially displacing relative to the support rod 1, thus ensuring stable operation.

[0031] In this embodiment, there are three tension holes 12, which are evenly distributed along the circumference of the support rod 1, thereby forming a stable three-point support structure for the speaker tray 10, resulting in better stability.

[0032] As a further improvement to the above solution, a control structure is also included. The support rod 1 is provided with an external thread. The control structure includes a threaded sleeve 6 that is threaded to the external thread of the support rod 1, several guide holes 13 located on the outer peripheral wall of the support rod 1 and extending through to the inner hole 11, and a connecting pin 7 located in the guide holes 13 and movable along the axial direction of the support rod 1. The inner peripheral wall of the threaded sleeve 6 is provided with an annular groove 61. The connecting pin 7 includes a first end connected to the base 3 and a second end that passes through the guide holes 13 and is slidably inserted into the annular groove 61. When the threaded sleeve 6 rotates, the annular groove 61 drives the connecting pin 7 and the base 3 to move along the axial direction of the support rod 1, so that the user can control the axial movement distance of the base 3 by rotating the threaded sleeve 6. This not only makes adjustment simple and convenient, but also provides good accuracy.

[0033] The specific shape of the guide hole 13 is not limited in this design. It is sufficient that the dimension of the guide hole 13 along the axial direction of the support rod 1 is greater than the dimension of the connecting pin 7 along the axial direction of the support rod 1, so that the connecting pin 7 is located within the guide hole 13 and can move along the axial direction of the support rod 1. In this embodiment, the guide hole 13 is an elongated hole with its long side parallel to the axial direction of the support rod 1. The connecting pin 7 slides against the wall of the long side of the guide hole 13, thereby allowing the wall of the long side of the guide hole 13 to support the connecting pin 7, enabling the connecting pin 7 to move more stably along the axial direction of the support rod 1.

[0034] In this embodiment, there are two guide holes 13, symmetrically distributed relative to the axis of the support rod 1. Connecting pins 7 are correspondingly arranged with each guide hole 13, allowing the annular groove 61 of the threaded sleeve 6 to more smoothly drive the base 3 to move via the two connecting pins 7. Furthermore, the base 3 has a pipe hole 32 inside, with an elastic element 8 inside. The outer peripheral wall of the base 3 has two assembly holes 33 extending through the pipe hole 32. The assembly holes 33 correspond to the guide holes 13. The first end of the connecting pin 7 is slidably inserted into the corresponding assembly hole 33. The two ends of the elastic element 8 are respectively connected to the first ends of the two connecting pins 7 and apply an outward pushing force to the two connecting pins 7, thereby ensuring the sliding insertion of the second end of the connecting pin 7 into the annular groove 61 while making assembly more convenient. In this embodiment, the elastic element 8 is a U-shaped spring sheet, with both ends connected to the first ends of the two connecting pins 7, thereby applying an outward pushing force to the two connecting pins 7; of course, the elastic element 8 can also be a spring or other parts with similar functions.

[0035] In this embodiment, a threaded sleeve 9 is fitted onto the outer side of the support rod 1. The thread of the sleeve 9 is used for screwing the threaded sleeve 6. The sleeve 9 and the support rod 1 are detachably connected, which facilitates replacement and maintenance. The detachable connection between the sleeve 9 and the support rod 1 can mean that threaded holes are provided on the outer peripheral wall of the sleeve 9 and the outer peripheral wall of the support rod 1, and the two are detachably connected by bolts. Alternatively, it can be a sleeve or snap-fit ​​connection in the form of an interference fit.

[0036] As an improvement to the above solution, it also includes a cover 5 and a mounting bolt 51. The cover 5 is located at the upper end of the support rod 1. The limiting plate 4 is connected to the upper end of the inner hole 11. The limiting plate 4 has a vertically opened mounting screw hole 42 in the middle. The cover 5 has a vertically opened through hole in the middle. The nut end of the mounting bolt 51 abuts against the upper side of the cover 5. The screw end of the mounting bolt 51 passes through the through hole and is screwed to the mounting screw hole 42 to achieve the sealing of the upper end of the inner hole 11 by the cover 5. The cover 5 helps to protect the inner hole 11 and prevent impurities from entering the inner hole 11.

[0037] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art will be able to make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of the invention.
