[0029] Reference Figure 1 and Figure 2As shown, the utility model provides a technical solution: a transparent liquid crystal display screen without backlight, comprising a display screen body 1, a lifting device 2 is provided on the surface of the display screen body 1, and the lifting device 2 is provided to achieve the effect of folding and protecting the display screen body 1, thereby preventing the display screen body 1 from being hit by foreign objects when the display screen body 1 is idle, thereby improving the protection of the device, and a supporting device 3 is provided on one side of the lifting warehouse 21, and the supporting device 3 is provided to achieve the effect of preventing the display screen body 1 from being knocked over, thereby preventing the display screen body 1 from being tilted after being hit by external force, thereby improving the safety of the device.

[0030] The specific configuration and functions of the lifting device 2 and the supporting device 3 are described in detail below.

[0031] Reference Figure 2 , Figure 3 and Figure 5As shown, in this embodiment: the lifting device 2 includes a lifting warehouse 21, the lifting warehouse 21 is slidably connected to the surface of the display screen body 1, and sliding holes are opened on both sides of the lifting warehouse 21. The inner surfaces of the sliding holes of the two lifting warehouses 21 are slidably connected with sliding plates 22. The sides of the two sliding plates 22 close to each other are fixedly connected to the display screen body 1. The surfaces of the sliding plates 22 are fixedly connected with fixing rods 23. The arc surface of the fixing rod 23 is slidably connected with an operating plate 24. The side of the operating plate 24 close to the sliding plate 22 is fixedly connected with an insertion rod 25. Two lifting warehouses 21 are opened on both sides. The end of the fixed rod 23 away from the sliding plate 22 is fixedly connected to the limit plate 27. The size of the plug rod 25 is adapted to the size of the slot of the lifting warehouse 21. When the staff pulls the operating plate 24, the operating plate 24 slides on the arc surface of the fixed rod 23. At this time, the limit plate 27 achieves the effect of limiting the maximum sliding distance of the operating plate 24 on the arc surface of the fixed rod 23, thereby avoiding the situation that the operating plate 24 is separated from the arc surface of the fixed rod 23 due to excessive pulling force when the staff pulls the operating plate 24. The arc surface of the fixed rod 23 is sleeved with a first spring 26, the two ends of the first spring 26 are fixedly connected to the operating plate 24 and the sliding plate 22 respectively. When the staff releases the operating plate 24, the resilience of the first spring 26 drives the operating plate 24 to slide on the arc surface of the fixing rod 23, and at the same time, the operating plate 24 drives the insertion rod 25 to move until the insertion rod 25 is inserted into the slot of the lifting warehouse 21. At this time, the first spring 26 improves the stability of the insertion rod 25 when limiting the sliding plate 22, thereby improving the stability of the insertion rod 25 when limiting the display screen body 1. The side of the sliding plate 22 close to the fixing rod 23 is fixedly connected with a screw 28, and the screw The arc surface of the rod 28 is threadedly connected with a strip plate 29. When the staff releases the limit of the sliding plate 22 by the insertion rod 25, they continue to pull the operating plate 24 until the operating plate 24 moves to the highest point of the fixed rod 23. At this time, the strip plate 29 is rotated to make the strip plate 29 threaded on the arc surface of the screw rod 28 until the strip plate 29 moves to the bottom of the operating plate 24. At this time, the strip plate 29 has the effect of limiting the movement of the operating plate 24, avoiding the situation where the insertion rod 25 is damaged due to friction with the surface of the lifting warehouse 21 when the staff moves the sliding plate 22.

[0032] Reference Figure 2 , Figure 4 and Figure 5The support device 3 comprises two fixing blocks 31, and the two fixing blocks 31 are fixedly connected to one side of the lifting warehouse 21. The two fixing blocks 31 are fixedly connected to a round rod 32 on one side close to each other. The arc surface of the round rod 32 is rotatably connected to a support plate 33. The arc surface of the round rod 32 is sleeved with two torsion springs 34. The two ends of the torsion spring 34 are fixedly connected to the fixing block 31 and the support plate 33 respectively. The lifting warehouse 21 is fixedly connected to one side close to the fixing block 31 with two connecting plates 35. The connecting plate 35 is internally threaded with a driving rod 36. One end of the driving rod 36 is rotatably connected to a connecting block 37. The surface of the supporting plate 33 is fixedly connected to two connecting plates 38. The surface of the connecting block 37 is slidably connected to the connecting plate 38. When the staff needs to transfer the display screen body 1, the supporting plate 33 can be retracted in advance, and the supporting plate 33 can be pressed to rotate on the arc surface of the round rod 32 until the supporting plate 33 is retracted. At this time, the driving rod 36 is rotated. The driving rod 36 is made to move in the internal thread of the connecting plate 35, and the driving rod 36 drives the connecting block 37 to move until the connecting block 37 is inserted into the connecting plate 38. At this time, the effect of limiting and fixing the support plate 33 is achieved, so that when the staff moves the display screen body 1, the support plate 33 occupies a large space, which makes it inconvenient for the staff to transfer the display screen body 1. The connecting block 37 is fixedly connected to a positioning rod 39 on the side close to the driving rod 36, and the arc surface of the positioning rod 39 is slidably connected to the connecting plate 35. When the staff rotates the driving rod 36, the driving rod 36 is made to move in the internal thread of the connecting plate 35, and the driving rod 36 drives the connecting block 37 to move, and the connecting block 37 drives the positioning rod 39 to slide in the connecting plate 35. At this time, the positioning rod 39 achieves the effect of limiting the connection block 37 to follow the rotation of the driving rod 36, so that the staff can quickly insert the connection block 37 into the connection plate 38, thereby improving the work efficiency of the staff.

[0033] Working principle: when the staff needs to retract the display screen body 1 for protection, they pull the operating panel 24 to make the operating panel 24 slide on the arc surface of the fixed rod 23, the first spring 26 is stretched, and the operating panel 24 drives the insertion rod 25 to move until the insertion rod 25 is disengaged from the slot of the lifting bin 21. At this time, the operating panel 24 is continued to be pulled until the operating panel 24 moves to the highest point of the fixed rod 23. At this time, the strip plate 29 is rotated to make the strip plate 29 threaded on the arc surface of the screw rod 28 until the strip plate 29 moves to the bottom of the operating panel 24. At this time, the sliding plate 22 is pulled to make the sliding plate 22 slide in the sliding hole of the lifting bin 21, and the sliding plate 22 drives the display screen The main body 1 slides in the lifting bin 21 until the display screen body 1 completely enters the lifting bin 21. At this time, the strip plate 29 is rotated to make the strip plate 29 threaded on the arc surface of the screw rod 28 until the strip plate 29 is disengaged from the bottom of the operating plate 24. At this time, the resilience of the first spring 26 drives the operating plate 24 to slide on the arc surface of the fixing rod 23. At the same time, the operating plate 24 drives the insertion rod 25 to move until the insertion rod 25 is inserted into the slot of the lifting bin 21. At this time, the display screen body 1 is folded and protected, avoiding the display screen body 1 from being hit by foreign objects when the display screen body 1 is idle, causing damage to the display screen body 1, thereby improving the protection of the device.

[0034] When the staff needs to support the display screen body 1 to prevent it from falling over, the staff rotates the driving rod 36 to make the driving rod 36 move in the inner thread of the connecting plate 35. At the same time, the driving rod 36 drives the connecting block 37 to move, and the connecting block 37 drives the positioning rod 39 to slide in the connecting plate 35 until the connecting block 37 is disengaged from the connecting plate 38. At this time, the torsion force of the torsion spring 34 drives the support plate 33 to rotate on the arc surface of the round rod 32 until the support plate 33 is unfolded. At this time, the effect of preventing the display screen body 1 from being knocked over is achieved, and the display screen body 1 is prevented from being tilted after being hit by external force, resulting in the display screen body 1 tipping over. The safety of the device is improved.
