DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of those skilled in the art, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0026] As Figure 1 , 2As shown, a mobile sound box with a rotatable lifting display comprises a box body 1, a display screen 2 is arranged on the top of the box body 1, a lifting air pressure rod 100 is arranged in the box body 1, the lifting air pressure rod 100 comprises a fixed rod 110 and a movable rod 120 which are connected with each other, the fixed rod 110 is connected with the box body 1, and the movable rod 120 is used for driving the display screen 2 to lift. A sleeve 121 is arranged on the movable rod 120, a sliding ring 122 is arranged at the bottom end of the sleeve 121, the sliding ring 122 is sleeved on the fixed rod 110, wire holes 123 are arranged on the top end of the sleeve 121 and the sliding ring 122, a spring wire tube 125 is arranged in the sleeve 121, the spring wire tube 125 is penetrated through the wire holes 123 on the top end of the sleeve 121 and the sliding ring 122, and cables (signal transmission lines, power lines, etc.) between the sound box and the display screen 2 are covered in the spring wire tube 125. The spring wire tube 125 plays a role of collecting the wire harness, can effectively prevent the wire harness from being scattered, and cooperates with the sleeve 121 to hide the cables in the sleeve 121, so that the cables are not exposed after the display screen 2 is lifted, and the appearance of the equipment is greatly improved. When the lifting air pressure rod 100 drives the display screen 2 to lift, the movable rod 120 drives the sleeve 121 to lift, and the spring wire tube 125 can also avoid that the cables directly rub against the wire holes 123 when the sleeve 121 and the sliding ring 122 lift, so as to reduce the abrasion of the cables.

[0027] As shown in Figure 3 , 7 , the top end of the box body 1 is also provided with a containing groove 11, when the display screen 2 is not used, the display screen 2 is fixed on the box body 1 in a horizontal state, and the containing groove 11 can hide and store various components on the back of the display screen 2, so as to provide protection and improve the appearance. A U-shaped support 12 for supporting the display screen 2 is arranged in the containing groove 11, the two side top ends of the U-shaped support 12 can prevent the display screen 2 from tilting in the horizontal state, and the two side top ends of the U-shaped support 12 are curved outward to avoid damaging the display screen 2.

[0028] As shown in Figure 2 , 6As shown, the lifting air pressure rod 100 and the box body 1 are further provided with a rotation limiting mechanism 150. Because the fixed rod member 110 and the movable rod member 120 have the relative rotation property, the display screen 2 can be rotated left and right by the lifting air pressure rod 100. However, if the movable rod member 120 is excessively rotated, the cable in the sleeve shell 121 will be wound and pulled. The rotation angle of the movable rod member 120 is limited by the rotation limiting mechanism 150. The rotation limiting mechanism 150 comprises a U-shaped rod 152 fixed in the box body 1. The outer wall of the sliding ring 122 is provided with a limiting column 151. The end of the limiting column 151 extends into the groove of the U-shaped rod 152. The U-shaped rod 152 cooperates with the limiting column 151 to limit the rotation of the sliding ring 122. Meanwhile, the limiting column 151 can still move up and down in the groove of the U-shaped rod 152, without affecting the lifting movement of the sliding ring 122. The sleeve shell 121 is provided with a strip-shaped opening 153 for the limiting column 151 to pass through. Because of the limitation of the U-shaped rod 152, the limiting column 151 cannot rotate. When the sleeve shell 121 is rotated by the movable rod member 120, the limiting column 151 will slide relative to the strip-shaped opening 153. When the sleeve shell 121 is continuously rotated in one direction, one end of the strip-shaped opening 153 will continuously approach the limiting column 151, until the limiting column 151 contacts one end of the strip-shaped opening 153 and cannot continue to rotate, achieving the purpose of limiting rotation.

[0029] As shown in Figure 3 , 4 , the top end of the movable rod member 120 is connected with a connecting frame 130. The connecting frame 130 is hinged with a turnover frame 140. The turnover frame 140 cooperates with the connecting frame 130 to support the display screen 2 to tilt and turn over at a certain angle. The connecting frame 130 comprises a bottom plate 131. Both ends of the bottom plate 131 are provided with first side plates 132. The turnover frame 140 comprises a turnover plate 141. Both ends of the turnover plate 141 are provided with second side plates 142. The two first side plates 132 are hinged with the two second side plates 142, respectively. The hinge of the first side plate 132 and the second side plate 142 realizes the turnover function of the turnover frame 140. The top end of the movable rod member 120 is connected with the bottom plate 131 by bolts and nuts. The valve 124 of the lifting air pressure rod 100 penetrates the bottom plate 131. The bottom plate 131 is hinged with an L-shaped pressing plate 133. The L-shaped pressing plate 133 is used to press the valve 124, realizing the lifting movement of the lifting air pressure rod 100. It should be noted that the lifting air pressure rod 100 is a common lifting mechanism. The bolt is a connecting component at the end of the bolt itself. Meanwhile, the position of the valve 124 is also existing and common. The bottom plate 131 is further provided with a cover plate 135 between the two first side plates 132. The cover plate 135 can avoid the exposure of the components on the bottom plate 131, protecting the components and providing certain aesthetics.
