[0002] LED display is an electronic display device used to display information such as images, videos and texts. It is widely used in various occasions. In the production of LED display, in order to ensure the quality of LED display, the quality and performance of LED display must be tested and evaluated first.

[0003] The existing LED display screen inspection usually requires the LED display screen to be placed in a fixed fixture and clamped in position before being inspected using a detection tool. However, since the curvature of the fixture cannot be adjusted, the positioning fixture needs to be replaced when inspecting LED displays with different curvatures, which is inconvenient.

[0004] Therefore, a LED display screen positioning fixture is now developed which can clamp LED display screens with different curvatures so as to facilitate testing of the LED display screens. Utility Model Content

[0005] In order to overcome the disadvantage of the existing LED display screen detection that the curvature of the fixture cannot be adjusted and the positioning fixture needs to be replaced when testing LED display screens with different curvatures, which is inconvenient, the utility model provides an LED display screen positioning fixture that can clamp LED display screens with different curvatures to facilitate testing of the LED display screen.

[0006] A positioning fixture for an LED display screen includes a mounting base, a support frame, a rotating shaft, a rotating frame, a limiting member, a screw rod and a clamping member. The left and right sides of the mounting base are connected to the supporting frames, the middle part of the mounting base is rotatably connected to multiple rotating shafts, the front and rear sides of the rotating shafts are connected to rotating frames, a limiting member is connected between the left and right rotating frames, the front and rear parts of the limiting member are both threadedly connected to the screw rods, the lower sides of adjacent screw rods are rotatably connected to the clamping member, the rotating frame is rotated to adjust, drive the rotating shaft to rotate, and drive the rotating frame on the other side to rotate relatively.

[0007] Optionally, a knob is also included, and the upper side of the screw rod is connected to the knob, and the screw rod is moved downward by turning the knob.

[0008] Optionally, it also includes gears, a locking wheel, a locking piece and an elastic piece. The front and rear parts of the rotating shaft are connected to gears, and adjacent gears are meshed with each other. The rear part of the right rotating shaft is connected to the locking wheel, and the rear part of the mounting seat is slidably connected to the locking piece. An elastic piece is connected between the locking piece and the mounting seat, and the locking piece is engaged with the locking wheel. When the locking piece is pulled to the right, the spring is squeezed and contracted, so that the locking piece disengages from the locking wheel, and the rotating frame is rotated to adjust the rotation, driving the rotating shaft to rotate, so that the gears mesh and rotate, and drive the rotating frame on the other side to rotate relatively, and the spring rebounds, so that the locking piece is reset and re-engaged with the locking wheel.

[0009] Optionally, reinforcing ribs are provided on the support frames.

[0010] Optionally, a cushion is provided on the underside of the clamp.

[0011] Optionally, the elastic member is a spring.
