Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

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

[0030] The fixing bracket includes a bottom plate 1, support columns 4 and a cover plate 5. Support columns 4 are vertically and fixedly installed at the four corners of the bottom plate 1, and the cover plate 5 is fixedly installed at the top of the support columns 4.

[0031] In this embodiment, four flat plates 9 are horizontally movably arranged inside the fixing frame. The four flat plates 9 are arranged at intervals up and down, and sound components are installed on the flat plates 9. Specifically, a guiding frame 10 is fixedly installed inside the fixing frame, and the flat plates 9 are slidably arranged inside the guiding frame 10 in a limited manner. The guiding frame 10 is fixedly connected to a limiting rod 7, and the limiting rod 7 limits the guiding frame 10 to prevent the flat plates 9 from separating from the guiding frame 10. The flat plates 9 slide outwards along the guiding frame 10, so that the flat plates 9 move outside the fixing frame, facilitating the maintenance of the sound components on the guiding frame 10.

[0032] Side plates 2 are arranged on the four sides of the fixing frame. The four side plates 2, the bottom plate 1, and the cover plate 5 enclose a closed space. The four side plates 2 correspond to the four flat plates 9 one by one, and the side plates 2 are connected to the corresponding flat plates 9. Specifically, a first sliding groove 19 is formed in the upper part of the side plate 2, and a first sliding block 20 is slidably arranged inside the first sliding groove 19. Each flat plate 9 is fixedly connected to a first connecting block 21, and the first sliding block 20 and the corresponding first connecting block 21 are hinged through a first hinge shaft.

[0033] A second sliding groove 12 is formed in the lower part of the side plate 2, and a second sliding block 11 is slidably arranged inside the second sliding groove 12 in a limited manner. The second sliding block 11 is hinged to a second connecting block 27 through a second hinge shaft. A telescopic member is arranged 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 extends, the side plate 2 and the flat plate 9 move towards the outside of the fixing frame. When the flat plate 9 contacts the limiting rod 7, under the limiting action of the limiting rod 7, the flat plate 9 cannot move further, and thus the lower end of the side plate 2 opens outwards.

[0034] In this embodiment, the telescopic member is a multi-section spring rod 18. Four mounting seats are fixedly installed on the bottom 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 both of the two first mounting seats 17 are fixed on the bottom plate 1 and are arranged in parallel. There are two second mounting seats 13, and the second mounting seats 13 are fixed on the first mounting seats 17. Both the second mounting seat 13 and the first mounting seat 17 are cylindrical, and the axis of the second mounting seat 13 is perpendicular to the axis of the first mounting seat 17. Multi-section spring rods 18 are fixedly installed inside both the second mounting seat 13 and the first mounting seat 17. The telescopic ends of the four multi-section spring rods 18 correspond to the four side plates 2 one by one. 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 arranged to move up and down inside the fixing frame. Specifically, third sliding grooves 14 are formed on all four support columns 4, and the four corners of the sliding plate 24 are limited and slidably arranged in the corresponding third sliding grooves 14. A threaded rod 16 is vertically rotatably installed inside the fixing frame, and the threaded rod 16 is threadedly connected to the sliding plate 24. The upper end of the threaded rod 16 penetrates upward through the cover plate 5 and is fixedly connected to a handle 6. The threaded rod 16 is located at a corner of the cover plate 5. By turning the handle 6, the threaded rod 16 rotates, and then the sliding plate 24 moves up and down along the third sliding groove 14.

[0036] Four sliding rods 23 are slidably connected to the sliding plate 24 up and down, 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 slidably passes through the corresponding mounting seat and is fixedly connected to a clamping block 15. A positioning groove 26 is formed at the telescopic end of the multi-section spring rod 18, and the clamping block 15 is inserted and matched with the corresponding positioning groove 26. The upper end of the sliding rod 23 slidably passes through the sliding plate 24 and is fixedly connected to a first limiting block 8. A second limiting block is fixed on the sliding rod 23, and the second limiting block is located between the sliding plate 24 and the corresponding mounting seat. A first spring 25 is sleeved on the sliding rod 23, 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 limiting block.

[0037] The lower part of the clamping block 15 is provided with a rounded corner, and a chamfered surface 22 is arranged at the end of each telescopic section of the multi-section spring rod 18. In this way, when the multi-section spring rod 18 extends, it is avoided that the clamping block 15 interferes with the extension of the multi-section spring rod 18.

[0038] Rollers 3 are arranged at the lower end of the side plate 2.

[0039] Working principle: Initially, the clamping 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 inside the fixing frame, and the bottom plate 1, the side plate 2 and the cover plate 5 enclose a closed space.

[0040] When maintenance is required, turn the handle 6, the threaded rod 16 rotates, the sliding plate 24 moves upward along the third sliding groove 14, the clamping block 15 moves upward, and the clamping block 15 moves out of the positioning groove 26. After losing the limit of the clamping block 15, 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 the flat plate 9 outward along the guiding frame 10. The four flat plates 9 move outward to the four sides of the fixing frame respectively, facilitating the maintenance of the audio components on the flat plate 9.

[0041] It should be noted that there is a certain rotational 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 simultaneously.

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

[0043] After the maintenance is completed and it is necessary to reset the side plate 2 and the flat plate 9, first turn the handle 6, the threaded rod 16 rotates, the sliding plate 24 moves downwards, the first spring 25 is compressed, and the lower end of the clamping block 15 abuts against the multi-section spring rod 18. Then, push the side plate 2 by hand to make the side plate 2 move towards the direction close to the fixing frame, and the multi-section spring rod 18 gradually contracts, and the lower end of the clamping block 15 slides along the multi-section spring rod 18. Until the side plate 2 returns to the initial state, that is, the side plate 2 fits onto the fixing frame, and the flat plate 9 returns into the fixing frame. At this time, when the clamping block 15 is opposite to the positioning groove 26, under the action of the first spring 25, the sliding rod 23 moves downwards, and the clamping block 15 is snapped into the positioning groove 26. Similarly, make the remaining side plates 2 all return to the initial state. Under the limitation of the clamping block 15, the multi-section spring rod 18 cannot move, and thus the side plate 2 is stably fixed on the fixing frame.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
