[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 The present invention provides an embodiment of a flip fixture for producing an LED display screen, comprising a base 1, a support plate 2 being mounted on the top of the base 1, a reduction motor 3 being disposed on the top of one side of the support plate 2, a rotating shaft 4 being connected to the output end of the reduction motor 3, and one end of the rotating shaft 4 passing through the other side of the support plate 2 and being provided with a clamping mechanism 5;

[0023] There are two sets of clamping mechanisms 5, and the two sets of clamping mechanisms 5 are slidably connected by the cooperation of two connecting slide rods 6;

[0024] The clamping mechanism 5 includes a main plate 501 with side fixing blocks 503 installed at both ends of the main plate 501. The clamping side of the main plate 501 is installed with two upper and lower limit clamps 502, and the two limit clamps 502 form a V-shaped distribution.

[0025] One end of the connecting slide rod 6 is fixedly connected to one side of the side fixing block 503, and the other end of the connecting slide rod 6 passes through the interior of different groups of side fixing blocks 503 arranged opposite to the side fixing block 503;

[0026] Specifically, such as Figure 1 、 Figure 2 and Figure 4 As shown, when in use, the special distribution of the limiting clamping plates 502 is utilized to achieve the fixing effect on the sides of LED display screens of different thicknesses, and the elastic effect of the clamping springs 8 is utilized to facilitate the left and right clamping mechanisms 5 to achieve the left and right limiting effect on the LED display screen;

[0027] A connecting slide rod 6 is installed on the side of the clamping mechanism 5 away from the support plate 2, and another clamping mechanism 5 is sleeved on the outside of the two connecting slide rods 6. A stopper 7 is installed on the outer end of the two connecting slide rods 6, and a clamping spring 8 is sleeved on the outside of the connecting slide rod 6 inside the stopper 7. At the same time, the inner end of the clamping spring 8 is connected to the outer side of the clamping mechanism 5 close to the stopper 7. A fitting mechanism 9 is provided on the opposite sides of the two sets of clamping mechanisms 5;

[0028] The fitting mechanism 9 includes a main airbag 901 installed at the center between two limiting clamps 502 in the same group. Side airbags 902 are installed on opposite sides of the limiting clamps 502 in the same group, and the side of the side airbag 902 close to the limiting clamps 502 is connected to one side of the main airbag 901 through a connecting tube 903.

[0029] The cross section of the main airbag 901 is an isosceles triangle, and the side airbags 902 are respectively located on the extension lines of the two isosceles sides of the isosceles triangle;

[0030] The cross section of the side airbag 902 is semicircular;

[0031] Specifically, such as Figure 1 、 Figure 3 As shown, when in use, the materials of the main airbag 901 and the side airbag 902 are used to increase the contact friction when they come into contact with the LED display screen, thereby reducing the sliding of the LED display screen and improving the clamping stability.

[0032] Working Principle: When using the present invention, the LED display screen is first clamped between the two limiting clamps 502 at the fixed end, so that one side of the LED display screen abuts against the main airbag 901. Then, the clamping mechanism 5 at the movable end is pulled outward, compressing the clamping spring 8, thereby abutting the other side of the LED display screen against the two limiting clamps 502 at the movable end. By utilizing the special distribution of the limiting clamps 502 and the elastic reset of the clamping spring 8, the clamping mechanism 5 clamps and limits the LED display screen to the left and right.

[0033] Secondly, as the left and right main airbags 901 abut against the sides of the LED display screen and are compressed, the gas in the main airbags 901 is transferred to the side airbags 902 through the connecting tubes 903, which in turn inflates the side airbags 902, squeezing the side of the LED display screen near the top surface, thereby further improving the clamping stability. At the same time, the main airbags 901 and the side airbags 902 are used to increase the contact friction between the limit clamping plate 502 and the LED display screen.

[0034] Finally, when the LED display needs to be rotated, the reduction motor 3 is started to make the shaft 4 drive the fixed end clamping mechanism 5 to rotate, and then drive the movable end clamping mechanism 5 to move synchronously, so that the front and back ends of the LED display can be adjusted.
