[0016] The following is combined with Figure 1-4 This application is described in further detail.

[0017] The embodiment of the present application discloses a hidden wiring device for a display screen for an exhibition, comprising a base 1, an upper surface of the base 1 is provided with an openable cover plate 2, the upper surface of the base 1 is provided with evenly distributed wire grooves 3, the inside of the wire grooves 3 are provided with U-shaped plates 4, and the lower surface of the cover plate 2 is provided with vertical grooves 5 adapted to the two side edges of the U-shaped plate 4, and a lifting mechanism is provided at the bottom of the U-shaped plate 4 so that the U-shaped plate 4 can slide relative to the vertical grooves 5.

[0018] Furthermore, the cover plate 2 moves horizontally relative to the base 1 , and one end of the cover plate 2 is fixedly connected to a guide rod 9 , which is horizontally arranged and inserted into the base 1 .

[0019] Furthermore, the lifting mechanism includes a trough body 6 opened at the bottom of the base 1, a top plate 7 is arranged in the trough body 6, and a connecting rod 11 is fixedly connected to the bottom of the U-shaped plate 4. The connecting rod 11 is vertically arranged, and the connecting rod 11 slides through the base 1 and is fixedly connected to the top plate 7, and a fixing mechanism is arranged on the surface of the top plate 7.

[0020] In actual use, first, open the cover 2, and then place the cables in the U-shaped plates 4 in each cable trough 3 in turn. After placement, close the cover 2, then move up the top plate 7, drive the connecting rod 11 and the U-shaped plate 4 to move up, and the U-shaped plate 4 moves toward the vertical groove 5 on the cover 2, so that the cables can be locked between the U-shaped plate 4 and the cover 2, and the top plate 7, the connecting rod 11 and the U-shaped plate 4 are fixed by setting a fixing mechanism.

[0021] The present application can place the cables one by one inside the cable trough 3 and arrange them neatly, and use the lifting mechanism to move the U-shaped plate 4 to lock the cables between the U-shaped plate 4 and the cover plate 2 to improve the stability of the cables. In actual use, the wiring device is placed behind the display screen to hide the cables.

[0022] Furthermore, springs 12 are sleeved on the surfaces of the connecting rods 11 on both sides, one end of the spring 12 is fixedly connected to the inner surface of the slot body 6 , and the other end of the spring 12 is fixedly connected to the top plate 7 .

[0023] In this embodiment, by setting the spring 12, when the top plate 7 is moved upward, the spring 12 sleeved on the surface of the connecting rod 11 is compressed. When the cable needs to be removed, the bolt 8 is first loosened, and the compressed spring 12 stretches, which can drive the top plate 7, the connecting rod 11 and the U-shaped plate 4 to reset, that is, the U-shaped plate 4 is moved out of the vertical groove 5, making it convenient to open the cover 2.

[0024] Furthermore, the fixing mechanism includes a baffle 10 fixed to one end of the top plate 7 , a bolt 8 is inserted into the surface of the baffle 10 , and the bolt 8 abuts against the surface of the base 1 .

[0025] In this embodiment, when the top plate 7 moves upward, the baffle 10 can abut against the surface of the cover plate 2 to limit the position of the cover plate 2 so that the cover plate 2 can stably cover the surface of the base 1 .
