Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 In this embodiment of the present invention, a home theater stereo system that is easy to assemble and disassemble includes a main speaker 1 and side speakers 2. A base plate 3 is provided below the main speaker 1. A connecting pipe 4 is symmetrically and fixedly connected to the bottom surface of the side speakers 2. An outer sleeve 5 is fixedly connected to the bottom surface of the base plate 3 at the corresponding location of the connecting pipe 4. An inner sleeve 6 that is adapted to the inner side of one end of the outer sleeve 5 is slidably connected to it. A guide sleeve 7 is fixedly connected to the inner side of the other end of the outer sleeve 5. An extension sleeve 8 that is adapted to the inner sleeve 6 is slidably connected to the guide sleeve 7. Both ends of the outer sleeve 5 are screwed together. The inner sleeve 6 is connected by a first locking bolt 9. One end of the first locking bolt 9 passes through the outer sleeve 5 and abuts against the outer wall of the inner sleeve 6. The other end of the first locking bolt 9 passes through both the outer sleeve 5 and the guide sleeve 7 and abuts against the extension sleeve 8. Both ends of the outer sleeve 5 are provided with threaded holes for the threaded connection of the first locking bolt 9. The guide sleeve 7 is provided with a round hole for the first locking bolt 9 to pass through. The inner sleeve 6 and the extension sleeve 8 are fixedly connected to the ends of the two sleeves that are far apart from each other. The plug 10 is inserted into the connecting tube 4 and is adapted to the connecting tube 4.

[0027] The outer sleeve 5, inner sleeve 6, and extension sleeve 8 are nested together and stored. The extension sleeve 8 is slidably guided by the guide sleeve 7 and further locked by the first locking bolt 9. This allows the distance between the connector 10 and the base plate 3 to be adjusted. The connector 10 is fixed by the connection of the connector 4 to the connecting pipe, thereby achieving the connection with the side speaker 2 and the main speaker 1. The spacing of the side speakers 2 can be adjusted by controlling the extension length of the inner sleeve 6 and the extension sleeve 8, so as to avoid the side speakers 2 from obstructing the display screen when the spacing is too small.

[0028] The connector 10 has a sliding cavity 11. The diameter of the middle part of the sliding cavity 11 is larger than the diameter of both ends, forming a shape that is larger inside and smaller outside. The sliding cavity 11 has symmetrically sliding protrusions 12. The tail end of the protrusion 12 is adapted to the inner cavity of the sliding cavity 11, and the head of the protrusion 12 is adapted to the end opening of the sliding cavity 11, thereby forming a sliding limiting effect to prevent the protrusions 12 from sliding out of the sliding cavity 11. The protrusions 12 are provided with a spring 13 that is adapted to the sliding cavity 11.

[0029] The connecting pipe 4 has a corresponding insertion hole 20 that matches the protrusion 12, and the protrusion 12 is inserted into the insertion hole 20.

[0030] The protrusion 12 is slidably connected in the sliding cavity 11 and forms elastic support through the spring 13. When the plug 10 is inserted into the connecting tube 4, the protrusion 12 is inserted into the plug hole 20, thereby forming a plug-in limit and thus forming an assembly, which facilitates the disassembly and assembly of the side speaker 2.

[0031] Both the connecting pipe 4 and the outer sleeve 5 are fixedly mounted with bullseye rollers 14.

[0032] Both the connecting tube 4 and the outer tube 5 are fixedly connected to the sides with extension ears 15. Threaded pads 16 are threadedly connected to the extension ears 15, and threaded holes for threaded connection of the threaded pads 16 are opened on the extension ears 15.

[0033] The stereo system is supported on the ground by bullseye casters 14, allowing it to be moved easily. It can also be supported on the ground by threaded feet 16, thus creating a stable parking effect.

[0034] Support tubes 17 are symmetrically fixedly connected to the four corners of the top surface of the base plate 3. Support rods 18 that are adapted to it are slidably connected inside the support tubes 17. Support rods 18 are fixedly connected to the bottom surface of the main speaker 1.

[0035] The top side wall of the support tube 17 is threaded with a second locking bolt 19, which is inserted into the support tube 17 and abuts against the outer wall of the support rod 18.

[0036] The support rod 18 can slide inside the support tube 17 and be locked in place by the second locking bolt 19, thereby allowing for easy adjustment of the support height of the main speaker 1.

[0037] The working principle of this utility model is as follows:

[0038] In use, the connector 10 is inserted into the connecting tube 4. During insertion, the protrusion 12 is pressed into the sliding cavity 11. When the protrusion 12 aligns with the socket 20, the spring 13 causes the protrusion 12 to pop out and insert into the socket 20, thus creating a limiting effect. At this point, the first locking bolt 9 is loosened, allowing the inner sleeve 6 to be pulled outward from the outer sleeve 5, and the extension sleeve 8 to be pulled outward along the guide sleeve 7. The side speaker 2 can then be moved outward via the bullseye roller 14 to adjust the spacing, thereby preventing obstruction of the display screen. After adjustment, the first locking bolt 9 is tightened to achieve a secure lock. The threaded foot 16 can then be rotated to rest against the ground, providing support. The support rod 18 can then be used to lift the support tube 17 upward, adjusting the height of the main speaker 1. The second locking bolt 19 can then be used to lock and secure the main speaker 1, achieving height adjustment.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
