DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 8 As shown, the technical solution adopted by the present invention is as follows: a combined audio structure includes a fixing frame, a side panel 2 and a flat panel 9.

[0030] The fixing frame comprises a bottom plate 1, a supporting column 4 and a cover plate 5. The supporting columns 4 are vertically fixedly installed at the four corners of the bottom plate 1, and the cover plate 5 is fixedly installed at the top of the supporting column 4.

[0031] In this embodiment, four flat plates 9 are arranged horizontally and movably in the fixed frame, and the four flat plates 9 are arranged at intervals in the upper and lower parts, and the sound components are installed on the flat plates 9. Specifically, a guide frame 10 is fixedly installed in the fixed frame, and the flat plates 9 are limitedly slidably arranged in the guide frame 10. The guide frame 10 is fixedly connected to the limit rod 7, and the limit rod 7 limits the guide frame 10 to prevent the flat plates 9 from being separated from the guide frame 10. The flat plates 9 slide outward along the guide frame 10, so that the flat plates 9 are moved outside the fixed frame, which is convenient for repairing the sound components on the guide frame 10.

[0032] The fixing frame is provided with side panels 2 on all sides. The four side panels 2, the bottom panel 1 and the cover panel 5 enclose a closed space. The four side panels 2 correspond to the four flat panels 9 one by one, and the side panels 2 are connected to the corresponding flat panels 9. Specifically, a first slide groove 19 is provided on the upper part of the side panel 2, and a first slider 20 is slidably provided in the first slide groove 19. Each flat panel 9 is fixedly connected to a first connecting block 21, and the first slider 20 and the corresponding first connecting block 21 are hinged through a first hinge shaft.

[0033] A second slide groove 12 is provided at the lower part of the side panel 2, and a second slider 11 is provided in the second slide groove 12 for limited sliding movement. The second slider 11 is hingedly connected to a second connecting block 27 via a second hinge shaft. A telescopic member is provided on the bottom plate 1, and the second connecting block 27 is fixedly connected to the telescopic end of the telescopic member. When the telescopic member is extended, the side panel 2 and the flat plate 9 move outward from the fixed frame. When the flat plate 9 contacts the limiting rod 7, the flat plate 9 cannot continue to move under the limiting action of the limiting rod 7, thereby causing the lower end of the side panel 2 to open outward.

[0034] In this embodiment, the telescopic member is a multi-section spring rod 18. Four mounting seats are fixedly installed on the base plate 1. Specifically, the mounting seat includes a second mounting seat 13 and a first mounting seat 17. There are two first mounting seats 17, and the two first mounting seats 17 are fixed on the base plate 1, and the two first mounting seats 17 are arranged in parallel. There are two second mounting seats 13, and the second mounting seats 13 are fixed on the first mounting seat 17. The second mounting seat 13 and the first mounting seat 17 are both cylindrical, and the axis of the second mounting seat 13 is perpendicular to the axis of the first mounting seat 17. The multi-section spring rod 18 is fixedly installed in the second mounting seat 13 and the first mounting seat 17. The telescopic ends of the four multi-section spring rods 18 correspond one by one to the four side plates 2. The telescopic ends of the multi-section spring rods 18 are fixedly connected to the corresponding second connecting blocks 27.

[0035] A sliding plate 24 is provided in the fixed frame for vertical movement. Specifically, the four support columns 4 are provided with third slide grooves 14, and the four corner limit sliding positions of the sliding plate 24 are provided in the corresponding third slide grooves 14. A threaded rod 16 is vertically rotatably installed in the fixed frame, and the threaded rod 16 is threadedly connected to the sliding plate 24. The upper end of the threaded rod 16 passes through the cover plate 5 upward and is fixedly connected to the handle 6. The threaded rod 16 is at a corner of the cover plate 5. When the handle 6 is turned, the threaded rod 16 rotates, and then the sliding plate 24 moves up and down along the third slide groove 14.

[0036] The sliding plate 24 is slidably connected to four sliding rods 23, and the four sliding rods 23 correspond to the four multi-section spring rods 18 one by one. The lower end of each sliding rod 23 slides through the corresponding mounting seat and is fixedly connected to the clamping block 15. The telescopic end of the multi-section spring rod 18 is provided with a positioning groove 26, and the clamping block 15 is plugged into the corresponding positioning groove 26. The upper end of the sliding rod 23 slides through the sliding plate 24 and is fixedly connected to the first limit block 8. A second limit block is fixed on the sliding rod 23, and the second limit block is located between the sliding plate 24 and the corresponding mounting seat. A first spring 25 is sleeved on the sliding rod 23, and the upper end of the first spring 25 is fixedly connected to the sliding plate 24, and the lower end of the first spring 25 is fixedly connected to the second limit block.

[0037] The bottom of the block 15 is provided with rounded corners, and the end of each telescopic joint of the multi-section spring rod 18 is provided with a chamfered surface 22. When the multi-section spring rod 18 is extended like this, the block 15 is prevented from interfering with the extension of the multi-section spring rod 18.

[0038] A roller 3 is provided at the lower end of the side plate 2 .

[0039] Working principle: Initially, the block 15 is inserted into the positioning groove 26, the multi-section spring rod 18 is in a shortened state, the flat plate 9 is in the fixed frame, and the bottom plate 1, the side plate 2 and the cover plate 5 enclose a closed space.

[0040] When maintenance is required, the handle 6 is turned, the threaded rod 16 rotates, the sliding plate 24 moves up along the third sliding groove 14, the block 15 moves up, and the block 15 moves out of the positioning groove 26. After the block 15 loses its limit, the multi-section spring rod 18 extends, and the multi-section spring rod 18 pushes the side plate 2 through the second connecting block 27, so that the side plate 2 moves outward. The side plate 2 drives the flat plate 9 to move outward along the guide frame 10. The four flat plates 9 move outward to the four sides of the fixing frame, respectively, so as to facilitate the maintenance of the audio components on the flat plate 9.

[0041] It should be noted that there is a certain rotation damping between the first hinge shaft and the first slider 20 and between the second hinge shaft and the second slider 11, so that in the initial stage of the extension of the multi-section spring rod 18, the multi-section spring rod 18 pushes the side plate 2 and the flat plate 9 to move outward at the same time.

[0042] As the plate 9 moves outward, when the plate 9 contacts the limit rod 7, the plate 9 stops moving under the limit of the limit rod 7. Then, as the multi-section spring rod 18 continues to extend, the second slider 11 slides in the second slide groove 12 and rotates around the first hinge axis, the first slider 20 slides in the first slide groove 19 and rotates around the second hinge axis, the lower end of the side plate 2 gradually opens outward, and the roller 3 rolls along the ground. The lower ends of the four side plates 2 are all opened outward, which increases the support area of ​​the bottom of the speaker, making the speaker more stable and preventing the speaker from accidentally tipping over during maintenance.

[0043] After the inspection is completed, when the side panel 2 and the flat plate 9 need to be reset, first turn the handle 6, the threaded rod 16 rotates, the sliding plate 24 moves down, the first spring 25 is compressed, and the lower end of the block 15 contacts the multi-section spring rod 18. After that, push the side panel 2 by hand to make the side panel 2 move toward the fixed frame, the multi-section spring rod 18 gradually shrinks, and the lower end of the block 15 slides along the multi-section spring rod 18. Until the side panel 2 returns to the initial state, that is, the side panel 2 is attached to the fixed frame, and the flat plate 9 returns to the fixed frame. At this time, when the block 15 is opposite to the positioning groove 26, under the action of the first spring 25, the sliding rod 23 moves down, and the block 15 is stuck in the positioning groove 26. Similarly, the remaining side panels 2 are returned to the initial state. Under the limit of the block 15, the multi-section spring rod 18 cannot move, so that the side panel 2 is stably fixed on the fixed frame.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
