[0016] Figure 2 is Figure 1 a rear view schematic diagram of

[0017] Figure 3 is Figure 2 an enlarged view of part A of

[0018] In the figure: 1 sound body, 2 moving wheels, 3 connecting rods, 4 grip rods, 5 support plates, 6 cross bars, 7 vertical bars, 8 chutes, 9 threaded rods, 10 sliding bars, 11 abutting rods, 12 rubber pads, 13 cylindrical grooves, 14 cylindrical rods, 15 springs. Specific embodiments

[0019] 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.

[0020] Refer to Figures 1 - 3 , a portable and adjustable sound, including a sound body 1. A plurality of moving wheels 2 are installed at the lower end of the sound body 1. The plurality of moving wheels 2 are all universal wheels. Here, according to specific requirements, the moving wheels 2 can be set to be larger to ensure that when moving, even when tilted, the right side of the support plate 5 will not touch the ground;

[0021] Among them, an adjustable handle mechanism is further included. The adjustable handle mechanism includes a cross bar 6 fixedly connected to the rear side of the sound body 1. Two vertical bars 7 are symmetrically and fixedly connected to the upper end of the cross bar 6. Chutes 8 are opened on the opposite sides of the two vertical bars 7. A sliding bar 10 is arranged above the cross bar 6. The two ends of the sliding bar 10 respectively extend into the corresponding chutes 8 and are slidably connected. A threaded rod 9 is rotatably connected to the upper end of the cross bar 6. The threaded rod 9 penetrates through the sliding bar 10 and is threadedly connected. Two connecting rods 3 are symmetrically and fixedly connected to the upper end of the sliding bar 10. The upper ends of the two connecting rods 3 are commonly fixedly connected with a grip rod 4;

[0022] Among them, a support mechanism is further included. The support mechanism is installed below the sound body 1. The support mechanism includes a support plate 5 arranged below the sound body 1. A rubber pad 12 is arranged at the lower end of the support plate 5. The upper end of the support plate 5 is elastically connected to the lower end of the sound body 1 through a plurality of springs 15. Two abutting rods 11 are fixedly connected to the upper part of the right side of the support plate 5. The two abutting rods 11 penetrate through the cross bar 6 and contact the lower end of the sliding bar

[0023] Among them, a plurality of cylindrical grooves 13 are opened at the lower end of the sound body 1. A plurality of cylindrical rods 14 are fixedly connected to the upper end of the support plate 5. The plurality of cylindrical rods 14 all extend into the cylindrical grooves 13 and are slidably connected. With this structure, the support plate 5 can move up and down more stably.

[0024] In the present invention, when in use, the sound is in Figure 1 position. At this time, the spring 15 is in a stretched state, the grip rod 4 moves down to the lowest position, the rubber pad 12 of the support plate 5 contacts the ground, the entire sound body 1 is in a relatively stable state, will not slide easily under external forces, and the overall occupied vertical space is less;

[0025] When it is necessary to move the sound box, turn the threaded rod 9 to drive the slider 10 to move upward. After the slider 10 moves upward, it will drive the grip rod 4 to move upward through the connecting rod 3, realizing the upward movement of the holding part. Moreover, by adjusting the threaded rod 9, any height adjustment within the adjustable range can be achieved, enabling people of any height to lift the luggage in the most suitable posture for themselves, reducing the pressure on the hands, shoulders and back;

[0026] In the above process, after the slider 10 moves upward, it no longer presses against the rod 11. Therefore, under the elastic action of the spring 15, the support plate 5 will move upward without hindering the movement of the moving wheel 2.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
