[0027] 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.

[0028] Implementation, for example Figure 1-8 As shown, this embodiment provides a rotatable video audio display screen device, including a main unit housing 1. A buckle 22 is provided on one side of the main unit housing 1, and a microphone 2 is detachably fixed to the main unit housing 1 via the buckle 22. A handle 3 is provided on the top of the main unit housing 1, and a display screen 4 is rotatably connected to the other side of the main unit housing 1. A rotating mechanism is provided between the main unit housing 1 and the display screen 4, and the rotating mechanism consists of a display screen section and a main unit housing section. The display screen section includes a detachably fixed, centrally symmetrically arranged locking plate 5 on the back center of the display screen 4. The locking plate 5 has several openings, and elastic locking feet 6 extend from each opening. Each opening and the elastic locking feet 6 are centrally symmetrically arranged around the center of the locking plate 5. Each elastic locking foot 6 has a hemispherical locking protrusion 7 facing the main unit housing 1 at its end. The locking plate 5 is centered... The main unit includes a prism insertion hole 10; the main unit housing includes a slot plate 8 fixed to the side wall of the main unit housing 1, the slot plate 8 has hemispherical slots 9 that match each hemispherical protrusion 7, the slot plate 8 has a circular hollow, and a circular turntable 9 is placed coaxially in the circular hollow. On the side of the turntable 9 facing the display screen 4, a prism 11 that matches the prism insertion hole 10 is coaxially fixed. The prism 11 is a quadrangular prism shaft. On the side of the turntable 9 facing the main unit housing 1, a rotating shaft is coaxially fixed and rotatably connected to the turntable 9. The turntable 9, the locking plate 5 and the display screen 4 are connected to each other by bolts. In this embodiment, a rotating mechanism is provided between the main unit housing 1 and the display screen 4. Through the hemispherical slots 9 and protrusions 7 in the rotating mechanism, the display screen 4 can be rotated and fixed at multiple angles relative to the main unit housing 1, so that the display screen 4 can be flexibly switched according to the software mode, improving the user experience.

[0029] The main housing of the rotating mechanism also includes a rotating buffer assembly. This assembly includes a radially opening groove 12 on the turntable 9, within which a slider 13 is slidably connected. The top of the slider 13 has a toothed head 14, and the bottom of the slider 13 has an elastic support assembly. The circular opening on the slot plate 8 is a toothed ring 15. Initially, the toothed head 14 engages with the toothed ring 15 under the action of the elastic support assembly. In use, the toothed head 14, along with the slider 13, is retracted into the groove 12 under the protection of the toothed ring 15. The elastic support assembly includes a support rod 16, one end of which is fixed to the bottom of the groove 12, and the other end of which is fixed to a spring 17. The slider 13 has an inner cavity with a bottom opening, and the other end of the spring 17 is fixed to the top of the inner cavity. The slider 13 is simultaneously slidably connected to the top of the support rod 16 through the inner cavity. In this embodiment, a rotating mechanism with a rotating buffer component is provided between the main unit housing 1 and the display screen 4. The rotating buffer component causes the display screen 4 to be subjected to a certain resistance during rotation, so as to avoid excessive rotation speed and inertia that would make it difficult to control.

[0030] The main unit housing 1 is equipped with a horizontal rotation mechanism at its bottom. This mechanism includes a slot 18 located at the center of the bottom of the main unit housing 1. Several vertical engaging protrusions are evenly distributed on the side wall of the slot 18. A matching vertical rotating column 19 is inserted into the slot 18. A base 20 is horizontally rotatably connected to the bottom of the rotating column 19, and a flexible rubber layer 21 covers the bottom surface of the base 20. In this embodiment, the horizontal rotation mechanism at the bottom of the main unit housing 1 allows for horizontal rotation. This means that when the main unit housing 1 needs to be turned, it is not necessary to completely lift it with the handle 3; simply rotating the main unit housing 1 is sufficient, which is quick and convenient. Furthermore, the flexible rubber layer 21 covering the bottom surface of the base 20 of the horizontal rotation mechanism increases the friction of the base 20 and allows it to flexibly adapt to surfaces with small protrusions.

[0031] In use, the display screen 4 is rotated relative to the main unit housing 1. During rotation, the latching protrusion 7 on the locking disc 5 will disengage from the slot 23 on the locking disc 8 under the action of the elastic locking foot 6, until the latching protrusion 7 re-enters the next slot 23 and engages. The turntable 9 rotates together with the prism 11. Under the action of the spring 17, the tooth 14 moves up and down on the toothed ring 15, and the slider 13 also moves back and forth in the slide groove 12, so that the rotation of the display screen 4 has resistance, preventing the display screen 4 from rotating too fast and causing the device to flip or be damaged. The main unit housing 1 can also rotate horizontally on the base 20. The flexible rubber layer 21 at the bottom of the base 20 can increase the friction of the base 20 and increase the adaptability of the base 20 to uneven surfaces.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
