FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model is described in detail below with reference to the figures and the specific embodiments.
Referring to fig. 1, the present invention provides a backlight mechanism of a camera test light box, including: the light box comprises a machine table, a light box arranged on the machine table, vertical supports 1 arranged on two sides inside the light box, a motor 21 arranged on one side of each vertical support 1, a first screw rod 22 connected with an output shaft of the motor 21, a first sliding block 221 sleeved on the screw rod 22, and a backlight source plate 3 connected with the first sliding block 221. The motor 21 drives the first slider 221 to reciprocate up and down along the first lead screw 22. When the relative distance between the backlight plate 3 in the light box and the camera to be measured needs to be adjusted, the motor 21 is started to drive the first screw rod 22 to rotate, so that the first sliding block 221 and the backlight plate 3 are driven to move up and down, and the distance between the backlight plate 3 and the camera is adjusted.
A second screw 23 is arranged on the vertical bracket 1 at the other side opposite to the motor 21. The first lead screw 22 and the second lead screw 23 are both provided with belt wheels 41, the belt wheels 41 are sleeved with transmission belts 42, and the first lead screw 22 transmits the kinetic energy of the motor 21 to the second lead screw 23 through the belt wheels 41 and the transmission belts 42. The second lead screw 23 is sleeved with a second slider 231, and the second slider 231 is connected with the backlight panel 3. When the motor 21 starts, the first lead screw 22 transmits the kinetic energy of the motor 21 to the second lead screw 23 through the belt wheel 41 and the transmission belt 42, so that the second lead screw 23 rotates synchronously with the first lead screw 22, the second slider 231 and the first slider 221 are driven to synchronously move up and down, the two sides of the backlight plate 3 are driven to move simultaneously, the stability of the movement of the backlight plate 3 is improved, the backlight plate 3 is always parallel to the plane of a machine table, and the accuracy of the detection result of the camera is ensured.
