[0002] As the market demand for LED displays grows, more and more manufacturers are emerging. During the production process, it is necessary to test the finished LED displays to ensure that the appearance and functions of the LED screens are in normal condition.

[0003] Traditional LED display testing equipment requires the use of a multimeter to measure the voltage and resistance of the display screen. However, the circuit board behind the display screen often has many points that need to be tested, requiring the testing personnel to walk around the testing table to better test the points on the front and back of the circuit board. This is inconvenient, as it requires the staff to walk back and forth, and there is a lack of fixation for the display screen. Often, the display screen is placed directly on the testing table, which can easily cause the display screen to fall. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an LED display screen testing device that has the advantages of fixing the display screen and allowing the testing platform to rotate, thus solving the problems mentioned in the background art.

[0022] In the above structure, the fixed seat 2 installed on the top of the support leg 1 and the ball bearing 5 installed in the inner cavity of the mounting groove 4 can lift the bottom of the testing table 3 under the action of the ball bearing 5 and the fixed seat 2, so that the testing table 3 can rotate better in the inner cavity of the fixed seat 2.

[0023] In a preferred embodiment: the top of the ball 5 contacts the bottom of the detection table 3, and the outer diameter of the ball 5 is smaller than the distance between the inner walls of the mounting groove 4.

[0024] In the above structure, the mounting groove 4 opened in the inner cavity of the fixed seat 2 and the ball bearing 5 installed on the inner wall of the mounting groove 4 can support the bottom of the testing table 3 under the action of the ball bearing 5, so that the testing table 3 can rotate better in the inner cavity of the fixed seat 2.

[0025] In a preferred embodiment, the two ends of the outer wall of the drive spring 9 are in contact with the inner wall of the mounting cylinder 7 and the outer wall of the moving plate 10, respectively, and the drive spring 9 is made of high carbon steel.

[0026] In the above structure, the driving spring 9 provided on the outer wall of the fixed rod 8 can drive the moving plate 10 under the action of the driving spring 9, so that the moving plate 10 moves towards the outer wall of the detection table 3 until the outer wall of the moving plate 10 is attached to the outer wall of the display screen body 13, thereby fixing the display screen body 13.

[0027] In a preferred embodiment, the two ends of the outer wall of the compression spring 12 are in contact with the outer wall of the clamping plate 11 and the outer wall of the moving plate 10, respectively, and the clamping plate 11 is made of natural rubber.

[0028] In the above structure, the compression spring 12 provided on the outer wall of the movable plate 10 can push the outer wall of the clamping plate 11 downward under the action of the compression spring 12, so that the clamping plate 11 can fit against the outer wall of the display body 13.

[0029] In a preferred embodiment, there are four rotating rods 14, and the four rotating rods 14 are respectively installed on the outer wall of the detection table 3.

[0030] In the above structure, the rotating rod 14 installed on the outer wall of the test platform 3 can drive the test platform 3 to rotate. When the test platform 3 rotates, it can drive the display screen body 13 on the top of the test platform 3 to rotate, so that the circuit boards on the display screen body 13 can rotate to a position close to the multimeter 15.
