[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0018] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0019] like Figures 1 to 4 As shown, a stable supporting display screen tray provided by an embodiment of the utility model comprises a placing plate 1 and a U-shaped supporting block 2, the top of the placing plate 1 is fixedly connected to the bottom of the U-shaped supporting block 2, a plurality of heat dissipation openings 3 are provided on the top of the placing plate 1, and the heat dissipation openings 3 are evenly distributed on the top of the placing plate 1, a rotating column 4 is movably connected to the front side of the left side of the U-shaped supporting block 2, a bidirectional screw 5 is fixedly installed on the right side of the rotating column 4, two moving blocks 6 are threadedly connected to the surface of the bidirectional screw 5, and the two moving blocks 6 are located at both ends of the bidirectional screw 5, a connecting rod 7 is fixedly connected to the top of the moving block 6, and a moving clamping plate 8 is fixedly connected to the top of the connecting rod 7, a plurality of auxiliary grooves 9 are provided on the top of the placing plate 1, and the auxiliary grooves 9 are evenly distributed on the top of the placing plate 1, four limiting columns 10 are threadedly connected to the bottom of the placing plate 1, the top of the limiting column 10 passes through the top of the placing plate 1, and the top of the limiting column 10 is fixedly connected to the connecting plate 11.

[0020] refer to Figure 4 The inner wall of the U-shaped support block 2 is provided with a notch 12 , which is used in conjunction with the bidirectional screw 5 , the moving block 6 and the connecting rod 7 .

[0021] By adopting the above scheme: by setting the notch 12, the bidirectional screw 5, the moving block 6 and the connecting rod 7 can have space for movement, reducing the contact area between the bidirectional screw 5, the moving block 6 and the connecting rod 7 and the U-shaped support block 2, reducing the wear of the bidirectional screw 5, the moving block 6 and the connecting rod 7, and extending the service life of the bidirectional screw 5, the moving block 6 and the connecting rod 7.

[0022] refer to Figure 4 The bottom of the moving block 6 is fixedly connected to a limit slider 13, and the internal sleeve of the limit slider 13 is connected to a limit slide rod 14. Both ends of the limit slide rod 14 penetrate the limit slider 13 and are fixedly connected to the inside of the U-shaped support block 2. The inner wall of the U-shaped support block 2 is provided with a limit slide groove 15 used in conjunction with the limit slider 13. The limit slide rod 14 is located in the limit slide groove 15, and the limit slide groove 15 is connected to the notch 12.

[0023] The above scheme is adopted: by setting the limit slider 13, the limit slide rod 14 and the limit slide groove 15, the moving block 6 can be moved more easily as the bidirectional screw 5 rotates, reducing the contact area between the moving block 6 and the U-shaped support block 2, avoiding the moving block 6 from getting stuck when moving, and also performing horizontal limit on the moving block 6, reducing the wear of the moving block 6, extending the service life of the moving block 6, and avoiding affecting the movement of the moving block 6.

[0024] refer to Figure 2 and Figure 4 Both ends of the bidirectional screw 5 are sleeved and connected with limit bearings 16, and the outer surface of the limit bearing 16 is fixedly connected to the inner wall of the U-shaped support block 2.

[0025] By adopting the above scheme: by setting the limit bearing 16, the two ends of the bidirectional screw 5 can be limited, which effectively avoids the shaking of the bidirectional screw 5 during rotation, and also reduces the contact area between the bidirectional screw 5 and the U-shaped support block 2, reduces the wear of the bidirectional screw 5, extends the service life of the bidirectional screw 5, and avoids affecting the rotation of the bidirectional screw 5.

[0026] refer to Figure 4 The inner wall of the U-shaped support block 2 is provided with an opening 17 , which cooperates with the connecting rod 7 , and is communicated with the notch 12 .

[0027] By adopting the above solution: by setting the opening 17, the connecting rod 7 can move with the moving block 6, reducing the contact area between the connecting rod 7 and the U-shaped support block 2, reducing the wear of the connecting rod 7, extending the service life of the connecting rod 7, and avoiding affecting the movement of the connecting rod 7.

[0028] refer to Figure 4One side of the rotating column 4 is fixedly connected to a limiting plate 18 , and the left side of the limiting plate 18 is threadedly connected to a threaded column 19 , and the threaded column 19 is threadedly connected to the left side of the U-shaped supporting block 2 .

[0029] By adopting the above solution, the limiting plate 18 and the threaded column 19 are provided to limit the rotation column 4, thereby preventing the rotation column 4 from rotating after the rotation, and avoiding the influence on the support clamping of the display screen.

[0030] The working principle of the utility model is as follows: when in use, the user places the display screen on the U-shaped support block 2, the user rotates the threaded column 19 to make the threaded column 19 disengage from the U-shaped support block 2, and then the user rotates the rotating column 4, the rotating column 4 rotates with the bidirectional screw 5, the bidirectional screw 5 drives the two moving blocks 6 on the bidirectional screw 5 to move relative to each other, the moving blocks 6 drive the connecting rod 7 to move, the connecting rod 7 drives the moving card plate 8 to move, so that the moving card plate 8 clamps the two sides of the display screen, and then the user rotates the threaded column 19 to fix the rotating column 4, rotates the limiting column 10, the limiting column 10 drives the connecting plate 11 to move, and the connecting plate 11 clamps the display screen, so that the tray supports the display screen stably.

[0031] To sum up: the display screen tray with stable support solves the problem that after the existing display screen is installed on the tray, the display screen has a certain shaking during the movement, making the tray unstable in supporting the display screen by setting a placement plate 1, a U-shaped support block 2, a heat dissipation port 3, a rotating column 4, a bidirectional screw 5, a moving block 6, a connecting rod 7, a moving card plate 8, an auxiliary groove 9, a limit column 10, a connecting plate 11, a notch 12, a limit slider 13, a limit slide rod 14, a limit slide groove 15, a limit bearing 16, an opening 17, a limit plate 18 and a threaded column 19.
