Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0025] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0026] An LED display screen adaptable to any angle, as Figures 1 to 6 shown, includes a bottom frame 100, a vertical arm 120 is movably assembled inside the bottom frame 100, a connecting arm 130 is rotatably connected inside the top end of the vertical arm 120, and a display screen 140 is movably arranged at the end of the connecting arm 130;

[0027] On both sides of the vertical arm 120 near the bottom end, there are auxiliary strips 121 rotatably connected and fitting with the inner wall of the bottom frame 100. A frame 110 is fixed to the inner wall of the bottom frame 100, and the bottom end of the frame 110 contacts the top end of the auxiliary strip 121. Multiple groups of suction cups 150 are installed at the bottom end of the bottom frame 100. Two piston chambers 160 communicating with the suction cups 150 are horizontally opened in the bottom frame 100. A piston 161 is slidably assembled in each piston chamber 160. A rotating column 170 extending to the bottom end inside the bottom frame 100 is at the central position inside the bottom frame 100. A piston rod 162 extending into the rotating column 170 is provided at the end of the piston 161. An extrusion groove 171 is opened at the contact position between the curved outer wall of the rotating column 170 and the piston rod 162;

[0028] A circular groove is opened at the contact position between the bottom frame 100 and the rotating column 170. An operation groove communicating with the piston chamber 160 is opened on one side of the circular groove. A return spring 163 is assembled on the outer wall of the piston rod 162 in the operation groove. The two ends of the return spring 163 are respectively fixed to the piston rod 162 and the operation groove. One end of the piston rod 162 located in the extrusion groove 171 is spherical.

[0029] When adjusting the angle, manually apply an external force to the two locking nuts 124 to make them no longer tightly connected to the connecting arm 130. Then, an external force can be applied to the display screen 140 to make it rotate upward or downward. Finally, rotate the locking nuts 124 to lock. At the same time, the vertical arm 120 and the auxiliary strips 121 on both sides can also be pulled to move inside the bottom frame 100, so as to change the position of the display screen 140 and achieve better adjustment of the angle and distance;

[0030] At the same time, before the bottom frame 100 is placed on the table, an external force is applied to the rotating column 170 to make it rotate. The extrusion groove 171 generates an extrusion force on the two piston rods 162 on both sides, making the piston 161 move inside the piston chamber 160. Then, the bottom frame 100 is placed on the table. At this time, the suction cups 150 are in contact with the table. Then, the rotating column 170 is rotated in the reverse direction, and the piston rod 162 moves horizontally and restores under the action of the return spring 163, making the space formed by the piston 161, the suction cup 150 and the table in a negative pressure state. Furthermore, the bottom frame 100 is firmly placed on the table to deal with the situation of the display screen 140 being warped due to its total weight, and further improve the protection purpose of the display screen 140;

[0031] When carrying it, press the bottom frame 100 and lift the display screen 140 upward to separate it from the connecting arm 130. Rotate the locking nuts 124 to make the connecting arm 130 rotatably enter the U-shaped groove opened in the vertical arm 120. Then, pull down the positioning rod 122 to release the locking effect between the vertical arm 120 and the auxiliary strip 121, and push the vertical arm 120 to rotate to the horizontal state. Invert the display screen 140 inside the bottom frame 100, and the frame 110 plays a supporting role, thereby reducing the overall occupied space of the device and facilitating packaging and carrying.

[0032] Please refer specifically to Figure 1 and Figure 3 , at the contact position between the top end of the vertical arm 120 and the connecting arm 130, a U-shaped groove is provided, and the size of the U-shaped groove is larger than the length dimension of the connecting arm 130. A locking nut 124 that contacts the connecting arm 130 is threadedly connected to the outer wall of the vertical arm 120. A positioning rod 122 extending into the auxiliary strip 121 is provided at a position slightly below the outer wall of the vertical arm 120. A restraint piece 123 fixed to the vertical arm 120 is movably sleeved on the outer wall of the positioning rod 122. A spring is sleeved on the outer wall of the positioning rod 122 at the top end of the restraint piece 123. Both ends of the spring are fixed to the restraint piece 123 and the positioning rod 122 respectively. A matching positioning hole is provided at the contact position between the top end of the auxiliary strip 121 and the positioning rod 122.

[0033] The provision of the U-shaped groove facilitates the rotation of the connecting arm 130 into coincidence with the vertical arm 120, thereby facilitating the folding and rotation with the vertical arm 120 into the bottom frame 100;

[0034] And when an upward external force is applied to the positioning rod 122, the spring is compressed and the bottom end is separated from the positioning hole, releasing the locking effect between the vertical arm 120 and the auxiliary strip 121. Subsequently, an external force can be applied to the vertical arm 120 to rotate it to a horizontal state around the contact point with the auxiliary strip 121, thereby being received into the bottom frame 100.

[0035] Please refer specifically to Figure 1 , a connecting frame is fixedly connected to the back surface of the display screen 140. A dovetail block is fixed to the end of the connecting arm 130. A dovetail groove for the sliding of the dovetail block is provided on the back surface of the connecting frame.

[0036] The cooperation between the dovetail block and the dovetail groove makes the disassembly and assembly of the display screen 140 time-saving and labor-saving.

[0037] Please refer specifically to the figure. At the contact position between the bottom end of the bottom frame 100 and multiple suction cups 150, a shallow groove 101 is provided.

[0038] Ensure that the bottom frame 100 can be in stable contact with the desktop, making the placement of its display screen 140 more stable.

[0039] Please refer specifically to Figure 1 , a rubber pad is pasted on the top end of the frame 110.

[0040] When the display screen 140 is inverted and placed in the bottom frame 100, the rubber pad is used to provide elastic protection for the display screen 140.

[0041] When in use and adjusting the angle, manually apply an external force to the two sets of locking nuts 124 to make them no longer tightly engage with the connecting arm 130. Then, an external force can be applied to the display screen 140 to rotate it upward or downward. Finally, rotate the locking nuts 124 to lock it. At the same time, the vertical arm 120 and the auxiliary strips 121 on both sides can be pulled to move within the bottom frame 100, thereby changing the position of the display screen 140 to achieve better adjustment of the angle and distance.

[0042] At the same time, before placing the bottom frame 100 on the table, apply an external force to the rotating column 170 to make it rotate. The extrusion groove 171 generates an extrusion force on the piston rods 162 on both sides, causing the pistons 161 to move within the piston chambers 160. Then, place the bottom frame 100 on the table. At this time, the suction cups 150 are in contact with the table. Then, rotate the rotating column 170 in the reverse direction, and the piston rods 162 move horizontally and return to their original positions under the action of the return springs 163, making the space formed by the pistons 161, the suction cups 150, and the table in a negative pressure state, thereby firmly fixing the bottom frame 100 on the table to prevent the situation of the display screen 140 tilting due to its total weight and further enhancing the protection of the display screen 140.

[0043] When carrying it, press the bottom frame 100 and lift the display screen 140 upward to separate it from the connecting arm 130. Rotate the locking nuts 124 to make the connecting arm 130 rotatably enter the U-shaped groove opened in the vertical arm 120. Then, pull down the positioning rod 122 to release the locking effect between the vertical arm 120 and the auxiliary strip 121, and push the vertical arm 120 to rotate to a horizontal state. Invert the display screen 140 into the bottom frame 100, and the frame 110 provides a supporting effect, thereby reducing the overall occupied space of the device and facilitating packaging and carrying. The parts not involved in this device are the same as or can be implemented using the prior art.

[0044] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments according to their needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
