[0039] Below, in conjunction with the accompanying drawings, a possible embodiment of the broadcast speaker bracket 10 in the present application is exemplarily described.

[0040] Figure 1 It is a three-dimensional structural schematic diagram of the broadcast speaker bracket 10 in this application; Figure 2 for Figure 1 One of the three-dimensional structural schematic diagrams of the broadcast speaker bracket 10 after the triangular bracket 110 is removed; Figure 3 for Figure 1 The second schematic diagram of the stereoscopic structure of the broadcast speaker bracket 10 after the triangular bracket 110 is removed. Figure 1-Figure 3As shown, the broadcast speaker bracket 10 in the present application includes: a base 120, a rotating base 210, a support frame 310 and a mounting arm 410. Among them, the rotating base 210 is installed on the base 120 and rotates around the first axis L1. The support frame 310 is installed on the rotating base 210, hinged with the rotating base 210, and rotates around the second axis L2. The mounting arm 410 is installed on the support frame 310, hinged with the support frame 310, and rotates around the third axis L3. The mounting arm 410 is provided with a mounting portion 411, and the mounting portion 411 is detachably connected to the broadcast speaker. The first axis L1, the second axis L2 and the third axis L3 intersect with each other. From the above, by making the first axis L1, the second axis L2 and the third axis L3 intersect with each other, the rotating base 210, the support frame 310 and the mounting arm 410 can be rotated in different directions respectively. Therefore, after the broadcast speaker is installed on the mounting portion 411 on the mounting arm 410, the broadcast speaker can be directed to different directions by rotating the rotating seat 210, the support frame 310 and the mounting arm 410, so that the angle of the broadcast speaker can be easily adjusted to improve the user experience.

[0041] In some embodiments, the first axis L1, the second axis L2 and the third axis L3 are perpendicular to each other. Thus, by making the first axis L1, the second axis L2 and the third axis L3 perpendicular to each other, the area distribution of the rotating seat 210, the support frame 310 and the mounting arm 410 can be made more uniform and reasonable. Thus, the angle adjustment range of the broadcast speaker can be expanded, and the user experience can be improved.

[0042] In some embodiments, Figure 2 , Figure 3 As shown, one end of the mounting arm 410 is hinged to the support frame 310, and the other end is provided with a mounting portion 411. Thus, by providing the mounting portion 411 at the other end of the support frame 310, the range of motion of the broadcast speaker can be increased after the broadcast speaker is connected to the mounting portion 411, so that the user can adjust the broadcast speaker as needed, thereby improving the user experience.

[0043] In some embodiments, Figure 2 , Figure 3 As shown, two mounting arms 410 are provided, and the two third axes L3 corresponding to the two mounting arms 410 are parallel. Thus, by providing two mounting arms 410, two broadcast speakers can be installed. By making the two third axes L3 corresponding to the two mounting arms 410 parallel, the rotation range of the two mounting arms 410 can be more reasonably allocated.

[0044] Figure 4 for Figure 2 Schematic diagram of the three-dimensional structure after the installation arm 410 is removed. In some embodiments, Figure 4 As shown, a telescopic hole 420 is provided on the support frame 310, and the telescopic hole 420 is located between the two third axes L3; a telescopic rod 430 is provided in the telescopic hole 420, and the telescopic rod 430 is slidably connected with the telescopic hole 420 along the direction of the telescopic hole 420; one end of the telescopic rod 430 extends out of the telescopic hole 420 and is hinged to one end of two connecting rods 440, and the other ends of the two connecting rods 440 are respectively hinged to the mounting arms 410 at the middle position of the two mounting arms 410. Thus, the mounting arms 410 are connected to the telescopic rod 430 through the connecting rod 440, and when one mounting arm 410 rotates to drive the telescopic rod 430 to slide in the telescopic hole 420, the other mounting arm 410 can be driven to rotate through the other connecting rod 440. Thus, not only can the linkage of the two mounting arms 410 be achieved, but also the two mounting arms 410 can be made more stable when rotating.

[0045] In some embodiments, a spring is disposed in the telescopic hole 420, and the spring drives the telescopic rod 430 to extend from the telescopic hole 420. Thus, the spring drives the telescopic rod 430 to extend from the telescopic hole 420, so that the two mounting arms 410 can be driven to rotate in a direction parallel to the direction of the telescopic hole 420, so that the mounting arms 410 can be easily stored. In addition, when the two mounting arms 410 are driven to separate, the spring can also provide resistance to make the rotation of the mounting arms 410 more stable.

[0046] In some embodiments, Figure 4 As shown, the telescopic hole 420 is oriented perpendicular to the plane where the two third axes L3 are located. Thus, the structure formed by the mounting arm 410, the connecting rod 440 and the telescopic rod 430 can be made more stable.

[0047] Figure 5 for Figure 4 Schematic diagram of the three-dimensional structure of the middle support frame 310 and the rotating base 210 separated. In some embodiments, Figure 4 , Figure 5 As shown, a limiting groove 212 is provided on the rotating seat 210, and the limiting groove 212 extends with the second axis L2 as the axis center; the support frame 310 is provided with a connector 313 at a position corresponding to the limiting groove 212, and the connector 313 extends into the limiting groove 212 and is slidably connected with the limiting groove 212; wherein, the length of the limiting groove 212 is set so that when the support frame 310 rotates to a position corresponding to a limited angle, the connector 313 abuts against the end of the limiting groove 212. Thus, by setting the limiting groove 212, the rotation angle of the support frame 310 can be limited, thereby improving the stability of the broadcast speaker bracket 10 when in use.

[0048] Figure 6 for Figure 5 Schematic diagram of the three-dimensional structure of the middle base 120 and the rotating base 210 separated. In some embodiments, as Figure 2 , Figure 3 , Figure 6 As shown, the base 120 is also provided with a first fastening bolt 220, the axis of which coincides with the first axis L1, and passes through the base 120 to be threadedly connected to the rotating base 210; the rotating base 210 is also provided with a second fastening bolt 320, the axis of which coincides with the second axis L2, and passes through the rotating base 210 to be threadedly connected to the mounting arm 410. Thus, the magnitude of the fastening force between the base 120 and the rotating base 210 can be adjusted by the first fastening bolt 220. When the angle needs to be adjusted by rotating the rotating base, the first fastening bolt 220 can be loosened to rotate the rotating base. When the adjustment is completed and the rotating base needs to be fixed, the first fastening bolt 220 can be tightened to fix the rotating base on the base 120. The second fastening bolt 320 can increase the fastening force between the rotating seat and the support frame 310. When the support frame 310 needs to be rotated to adjust the angle, the second fastening bolt 320 can be loosened to rotate the support frame 310. When the adjustment is completed and the support frame 310 needs to be fixed, the second fastening bolt 320 can be tightened to fix the support frame 310 on the rotating seat.

[0049] In some embodiments, Figure 1 As shown, the broadcast speaker bracket 10 also includes a triangular bracket 110, which is detachably connected to the base 120 and is arranged at a side away from the rotating base 210. Therefore, by setting the triangular bracket 110, the broadcast speaker bracket 10 can be conveniently placed on the ground, thereby improving the stability of the broadcast speaker bracket 10 and further improving the stability of the broadcast speaker.

[0050] The above content is an exemplary description of a possible embodiment of the broadcast speaker bracket 10 in the present application. Next, in conjunction with the accompanying drawings, the specific structure of the broadcast speaker bracket 10 in the present application is described in detail in a specific embodiment.

[0051] like Figure 1As shown, the broadcast speaker bracket 10 in the present application is used to install the broadcast speaker, including a support mechanism 100, a first adjustment mechanism 200, a second adjustment mechanism 300 and a third adjustment mechanism 400. Among them, the support mechanism 100 is used to provide support when placing the broadcast speaker bracket 10 to improve the stability of the broadcast speaker bracket 10. The first adjustment mechanism 200 is installed on the support mechanism 100, so that the broadcast speaker can rotate around the first axis L1 as the axis. The second adjustment mechanism 300 is installed on the first adjustment mechanism 200, so that the broadcast speaker can rotate around the second axis L2 as the axis. The third adjustment mechanism 400 is installed on the second adjustment mechanism 300, so that the broadcast speaker can rotate around the third axis L3 as the axis. Among them, the first axis L1 is vertically arranged, and the first axis L1, the second axis L2 and the third axis L3 are perpendicular to each other.

[0052] like Figure 1 As shown, the support mechanism 100 includes a triangular bracket 110 and a base 120. The triangular bracket 110 has three rod-shaped legs, and the three legs of the triangular bracket 110 have two states: a storage state and an open state. In the storage state, the three legs are close together to reduce the space occupied and facilitate storage. In the open state, the three legs are connected at one end and separated at the other end, so that the triangular bracket 110 forms a triangular cone, so that the stability of the triangular bracket 110 can be improved when the triangular bracket 110 is placed on the ground. The base 120 is disc-shaped, and the base 120 is detachably connected to the top of the triangular bracket 110 on the lower surface.

[0053] like Figure 1-Figure 6 As shown, the first adjustment mechanism 200 includes a rotating seat 210 and a first fastening bolt 220. The rotating seat 210 is disc-shaped at the lower end facing the base 120 to facilitate connection with the base 120 and rotate around the first axis L1. The axis of the first fastening bolt 220 coincides with the first axis L1. The first fastening bolt 220 passes through the base 120 from the bottom of the base 120 and is threadedly connected to the rotating seat 210. The rotating seat 210 can be locked by tightening the first fastening bolt 220 to prevent the rotating seat 210 from rotating. The upper end of the rotating seat 210 is cylindrical, and a connecting hole 211 is provided at the axis position of the upper end of the rotating seat 210. The axis of the connecting hole 211 coincides with the second axis L2, and is used to be hinged with the following connecting shaft 312 at the lower end of the support frame 310. A limiting groove 212 is also provided on the outer circumferential surface of the upper end of the rotating seat 210. The limiting groove 212 extends along the circumferential direction of the upper end of the rotating seat 210, and the axis of the limiting groove 212 coincides with the second axis L2. Two limiting grooves 212 are provided, which are respectively used to slide with the following connector 313 at the lower end of the support frame 310.

[0054] like Figure 2-Figure 5As shown, the second adjustment mechanism 300 includes a support frame 310 and a second fastening bolt 320. Among them, the upper end of the support frame 310 is U-shaped when viewed along the extension direction of the second axis L2, that is, openings are formed at both sides, so that after the mounting arm 410 is installed inside the U-shaped portion of the upper end of the support frame 310, it can rotate at the notch position. A connecting plate 311 is provided at the middle position of the lower end of the support frame 310, and a connecting shaft 312 is provided at the end of the connecting plate 311, and the axis of the connecting shaft 312 is perpendicular to the extension direction of the connecting plate 311. The axis of the connecting shaft 312 coincides with the second axis L2, is provided in the connecting hole 211 at the upper end of the rotating seat 210, and is hinged to the connecting hole 211. Two connecting heads 313 are also provided at the lower end of the support frame 310, and the other connecting heads 313 are respectively provided at the two sides of the connecting plate 311, and are respectively slidably connected to the two limiting grooves 212. When the support frame 310 rotates to a predetermined angle, the connector 313 abuts against the end of the limiting groove 212, thereby limiting the rotation angle of the support frame 310. The axis of the second fastening bolt 320 coincides with the second axis L2, and passes through the upper end of the rotating seat 210 from one side of the axis of the upper end of the rotating seat 210 and is threadedly connected to the connecting shaft 312. By tightening the second fastening bolt 320, the connecting shaft 312 can be locked in the connecting hole 211, so that the support frame 310 cannot rotate on the rotating seat 210 with the second axis L2 as the axis.

[0055] like Figure 2-Figure 5As shown, the third adjustment mechanism 400 includes a mounting arm 410, a telescopic hole 420, a telescopic rod 430 and a connecting rod 440. The mounting arm 410 is a rectangular component as a whole, and one end of the mounting arm 410 is hinged to the support frame 310 in the U-shaped interior of the upper end of the support frame 310, so that the mounting arm 410 can rotate around the third axis L3, and the third axis L3 is perpendicular to the second axis L2 and the extension direction of the connecting plate 311. The other end of the mounting arm 410 is provided with a mounting portion 411, and the mounting portion 411 is used for detachable connection with the broadcasting speaker. There are two mounting arms 410, and the two mounting arms 410 are parallel to the two third axes L3 at the hinged position of the support frame 310, and the same plane where the two third axes L3 are located is perpendicular to the extension direction of the connecting plate 311. The telescopic hole 420 is provided on the support frame 310, located in the middle of the two mounting arms 410, and the direction of the telescopic hole 420 is opposite to the extension direction of the connecting plate 311. The telescopic rod 430 is inserted into the telescopic hole 420 and is slidably connected to the telescopic hole 420. A spring is also provided in the telescopic hole 420 to push the telescopic rod 430 to extend outward. Two connecting rods 440 are provided, one end of the two connecting rods 440 is hinged to the end of the telescopic rod 430 extending outward, and the other end is respectively hinged to the two mounting arms 410. The hinge position of the connecting rod 440 and the mounting arm 410 is located near the hinge position of the mounting arm 410 and the support frame 310, so that when the mounting arm 410 rotates toward the telescopic hole 420, the telescopic rod 430 can be driven to extend outward, and when the mounting arm 410 rotates away from the telescopic hole 420, the telescopic rod 430 can be driven to retract toward the telescopic hole 420.

[0056] like Figure 2 , Figure 3 As shown, the distance between the two mounting arms 410 and the hinged position of the support frame 310 is set such that when the two mounting arms 410 rotate to a position parallel to the direction of the telescopic hole 420, the two mounting arms 410 fit together. An accommodating space is provided at one side of the two mounting arms 410 facing each other, and the size of the accommodating space is adapted to the size of the telescopic hole 420 and the telescopic rod 430. When the two mounting arms 410 are attached together, the telescopic hole 420 and the telescopic rod 430 can be accommodated in the accommodating space.
