DETAILED DESCRIPTION
[0019] The utility model will be further described below in combination with the drawings and specific embodiments to help understand the contents of the utility model.
[0020] For example, Figure 1The utility model provides a display screen test frock, including workbench 1, workbench 1 mirror image is provided with two groups of support assembly 3, support assembly 3 has the function of unfolding and folding.
[0021] As Figure 2 , 3 shows, support assembly 3 includes base 4, base 4 is fixedly connected in storage groove 2, base 4 is hinged with support rod 5, the middle part of support rod 5 is rotationally cooperated with bottom frame support 7, the top surface of bottom frame support 7 is fixedly connected with rubber cover 8, and rubber cover 8 is shaped as "N", for clamping the bottom frame of liquid crystal screen. The top of support rod 5 is fixedly connected with the side frame support 10 extending to both sides, as Figure 4 , two grooves 12 are set up on the side frame support 10, one is located on the back of side frame support 10, and one is located on the bottom surface of side frame support 10. The sliding block 20 is slidably connected on the groove 12, the moving seat 14 is fixedly connected on the sliding block 20, and the width adjusting rod 11 perpendicular to bottom frame support 7 is fixedly connected on the moving seat 14. The scale plate 17 is further set up on the width adjusting rod 11, and the scale plate 17 is located on the path of groove 12, for showing the distance between the two width adjusting rods 11.
[0022] As Figure 4 , one side of scale plate 17 extends to the groove 12 above the back of side frame support 10, and a plurality of adjusting grooves 13 are linearly arranged. The insert block 16 is set up on the moving seat 14 and matched with the adjusting groove 13, the spring 15 is set up on the bottom of insert block 16, so that insert block 16 can be separated from adjusting groove 13 or clamped in adjusting groove 13.
[0023] As Figure 3 , the insertion groove 18 is further set up on the base 4, and the vertical first limiting block 6 is matched on the insertion groove 18, so that the support rod 5 can keep the inclined state after unfolding. The second limiting block 9 is fixedly connected in the middle part of support rod 5, so that the bottom frame support 7 can keep the state perpendicular to support rod 5 after unfolding.
[0024] When unfolding support assembly 3, the support rod 5 is lifted from the storage groove 2, the first limiting block 6 is vertically inserted on the insertion groove 18, so that the support rod 5 keeps the inclined state, then the bottom frame support 7 is turned over, so that it is perpendicular to the support rod 5, the insert block 16 is pressed, according to the scale of scale plate 17, the distance between the two moving seats 14 is moved to be consistent with the width of the placed liquid crystal screen, finally the bottom frame of liquid crystal screen is placed in the rubber cover 8, and the two width adjusting rods 11 limit the two sides of liquid crystal screen, so that the liquid crystal screen in the inclined state is clamped.
[0025] When the support assembly 3 is folded, first, the bottom frame support 7 is turned to be parallel to the support rod 5, then the first limiting block 6 is taken off from the slot 18, then the support rod 5 is placed inside the storage slot 2, and finally the liquid crystal screen is placed on the workbench 1, and the two width adjusting rods 11 limit the two sides of the liquid crystal screen.
