The angle adjusting device 12 is located between the display screen units 11 and used for adjusting the angle between the display screen units 11 to enable the adjustable display screen to have radian.
In the present embodiment, referring to fig. 4 and fig. 7, the angle adjusting device 12 includes a fixing mechanism 121 and a connecting mechanism 122, the fixing mechanism 121 includes a first connecting block 1211 and a second connecting block 1212 which are longitudinally arranged side by side, and the first connecting block 1211 and the second connecting block 1212 respectively extend into the receiving grooves 111 of two adjacent display screen units 11 and are fixedly connected with the display screen units 11. First link block 1211 and second link block 1212 each have first hinge point 1213 and second hinge point 1214.
Specifically, the first connecting block 1211 is further provided with an indicating rod 1215, and the indicating rod 1215 is provided with an indicating arrow 1216. An angle rod 1217 is further arranged on the second connecting rod 1212, and an angle ruler 1218 is arranged on the angle rod 1217. Indicator stem 1215 cooperates with angle stem 1217 to indicate that arrow 1216 is aligned with angle 1218, and that arrow 1216 is directed to a different position on angle 1218 as the angle between first attachment block 1221 and second attachment block 1222 changes.
The indication arrow 1216 and the angle scale 1218 used in this embodiment can display the angle between the first connection block 1221 and the second connection block 1222 in real time. Of course, in other embodiments, other angle indicating devices may be used.
The connecting mechanism 122, which is used to movably connect the first connecting block 1211 and the second connecting block 1212, includes two first connecting rods 1221 and two second connecting rods 1222. And a first connecting rod 1221 and a second connecting rod 1222 are respectively arranged on the first connecting block 1211 and the second connecting block 1212, the first connecting rod 1221 is provided with a first end hinge point 1223 and a tail end hinge point 1224, and the second connecting rod 1222 is provided with a first end hinge point 1225, a middle end hinge point 1226 and a tail end hinge point 1227 which are not in the same straight line. On each link block, the first link rod head end hinge point 1223 coincides with the link block first hinge point 1213, and the second link rod head end hinge point 1225 coincides with the first link rod tail end hinge point 1224. The end hinge point 1227 of the second connecting rod coincides with the second hinge point 1214 on the other fixing seat, and the middle end hinge points 1226 of the two second connecting rods coincide.

This allows the connecting mechanism 122 to form a double parallelogram structure, which allows the first connecting block 1211 and the second connecting block 1212 to rotate with a small force during operation. And this structure is equivalent to moving up articulated position, has both realized the seamless concatenation of display screen unit 11 (theoretically, can realize seamless concatenation with the contact point of two display screen units 11 as the pin joint, actually can't set up because of the contact point position is too little), has avoided two LED display screen units 11 collision when rotatory again effectively.
Specifically, the angle adjusting device 12 further includes a pin 123, the first hinge point 1213 of the connecting block is rotatably connected to the first hinge point 1223 of the first connecting rod through the pin 123, the first hinge point 1225 of the second connecting rod is rotatably connected to the second hinge point 1224 of the first connecting rod through the pin 123, the second hinge point 1227 of the second connecting rod is rotatably connected to the second hinge point 1214 of the other fixing base through the pin 123, and the middle hinge points 1226 of the two second connecting rods are rotatably connected through the pin. The connecting rod has the advantages of simple structure, low processing cost and firm connection.
The angle adjusting means 12 described in the present embodiment is only one of alternatives, and any means that can achieve an angular change of the display screen unit 11 around a position may be substituted.
As shown in fig. 5 and 7, when the angle between the first connection block 1221 and the second connection block 1222 is 180 °, the two display screen units 11 are located on the same horizontal plane; as shown in fig. 6 and 8, when the angle between the first connection block 1221 and the second connection block 1222 is less than 180 °, the two display screen units 11 have an outer arc shape; as shown in fig. 1 and 4, when the angle between the first connection block 1221 and the second connection block 1222 is greater than 180 °, the two display screen units 11 have an inner arc shape.
