The second fastener 90 is inserted into the second strip hole 23 and the second positioning hole 41 to fix the second positioning bar 40 on the support surface. In this way, the display screen to be tested is stably fixed on the operating table 20. The display screen lighting test fixture of this application can fix various display screens of different sizes by adjusting the distance between the first positioning bar 30 and the fixing bar 50 in the first direction X, and adjusting the distance between the second positioning bar 40 and the stop bar 70 in the second direction Y. It is highly flexible and practical. Moreover, by fixing the display screen on the fixture for lighting test, the display screen is not easily damaged, effectively ensuring the quality of the display screen product.

[0046] In one embodiment of this application, please refer to Figure 2 The support assembly 10 includes a support base 11 and a universal adjuster 12 mounted on the support base 11. The universal adjuster 12 is connected to the side of the operating table 20 away from the operating surface 21.

[0047] The operating table 20 is connected to the support base 11 via the universal adjuster 12, so that the angle of the operating table 20 can be adjusted by the universal adjuster 12 to adjust the angle of the display screen fixed on the operating table 20 to meet the needs of testing the display screen at different angles.

[0048] In one embodiment of this application, please refer to Figure 2 The universal adjuster 12 includes an adjusting seat 121, an adjusting shaft 122, and a locking rod 123. The adjusting seat 121 is mounted on the support seat 11. The adjusting seat 121 is provided with a ball groove 1211. One end of the adjusting shaft 122 is provided with a ball head 1221 that is movably embedded in the ball groove 1211. The other end of the adjusting shaft 122 is connected to the side of the operating table 20 away from the operating surface 21. The locking rod 123 is adjustablely inserted into the adjusting seat 121 to lock the ball head 1221.

[0049] When adjusting the angle of the operating table 20, loosen the locking lever 123 so that the ball head 1221 can rotate in the ball groove 1211. When the display screen on the operating table 20 is adjusted to the required angle, tighten the locking lever 123 to lock the ball head 1221 in the ball groove 1211, effectively ensuring the stability of the display screen at the required angle.

[0050] In one embodiment of this application, please refer to Figure 1 The first positioning strip 30, the second positioning strip 40, the fixing strip 50, the support strip 60, and the stop strip 70 are all silicone strips.

[0051] By using silicone strips for the first positioning strip 30, the second positioning strip 40, the fixing strip 50, the support strip 60, and the stop strip 70, the display screen is buffered, effectively preventing the display screen from colliding hard with the operating table 20 and damaging the display screen.

[0052] It should be noted that the silicone strip used has a preset structural strength and flexibility, which allows the first positioning strip 30, the second positioning strip 40, the fixing strip 50, the support strip 60 and the stop strip 70 to work together to stably limit the position of the display screen, while also providing a buffering effect for the display screen.

[0053] In one embodiment of this application, please refer to Figure 1 and Figure 3 There are two first strip holes 22, which are arranged parallel to each other along the second direction Y. The two ends of the first positioning strip 30 are respectively provided with first positioning holes 31 that correspond to and communicate with the two first strip holes 22.

[0054] When the first positioning strip 30 is adjusted to a preset position along the first direction X, one of the first fasteners 80 is inserted into one of the first strip holes 22 and the corresponding first positioning hole 31, and another first fastener 80 is inserted into another first strip hole 22 and the corresponding first positioning hole 31. This helps to improve the stability of the first positioning strip 30 on the operating surface 21, so that the first positioning strip 30 can be more stably fixed to the display screen in the first direction X by cooperating with the fixing strip 50.

[0055] Of course, in other embodiments, the number of first strip holes 22 may be one, three or more, and the number of first positioning holes 31 on the first positioning strip 30 is equal to the number of first strip holes 22.

[0056] In one embodiment of this application, please refer to Figure 1 and Figure 3 There are two second strip holes 23, which are arranged parallel to each other along the first direction X. The two ends of the second positioning strip 40 are respectively provided with second positioning holes 41 that correspond to and communicate with the two second strip holes 23.

[0057] When the second positioning strip 40 is adjusted to the preset position along the second direction Y, one of the second fasteners 90 is inserted into one of the second strip holes 23 and the corresponding second positioning hole 41, and the other second fastener 90 is inserted into the other second strip hole 23 and the corresponding second positioning hole 41. This helps to improve the stability of the second positioning strip 40 on the operating surface 21, so that the second positioning strip 40 can be more stably fixed to the display screen in the second direction Y by cooperating with the stop strip 70.

[0058] Of course, in other embodiments, the number of second strip holes 23 may be one, three or more, and the number of second positioning holes 41 on the second positioning strip 40 is equal to the number of second strip holes 23.

[0059] In one embodiment of this application, please refer to Figure 1 and Figure 3 There are two support bars 60, namely a first support bar 61 and a second support bar 62, which are arranged parallel to each other along the first direction X. By using the first support bar 61 and the second support bar 62 to support the display screen simultaneously, the stability of the display screen support is effectively improved, and the structure is simple.

[0060] In one embodiment of this application, please refer to Figure 1 and Figure 3 The operating table 20 is also provided with a third strip hole 24 and a fourth strip hole 25 extending along the first direction X. The first support bar 61 is provided with a third positioning hole 611 corresponding to and communicating with the third strip hole 24. The third fastener 100 is inserted into the third strip hole 24 and the corresponding third positioning hole 611. The second support bar 62 is provided with a fourth positioning hole 621 corresponding to and communicating with the fourth strip hole 25. The fourth fastener 110 is inserted into the fourth strip hole 25 and the corresponding fourth positioning hole 621.

[0061] By connecting the third positioning hole 611 on the first support bar 61 with the corresponding third strip hole 24, the first support bar 61 can be adjusted along the first direction X on the operating surface 21. After adjusting the first support bar 61 to a preset position, a third fastener 100 is inserted into the third strip hole 24 and the corresponding third positioning hole 611 to fix the first support bar 61 on the operating surface 21. By connecting the fourth positioning hole 621 on the second support bar 62 with the corresponding fourth strip hole 25, the second support bar 62 can be adjusted along the first direction X on the operating surface 21. After adjusting the second support bar 62 to a preset position, a fourth fastener 110 is inserted into the fourth strip hole 25 and the corresponding fourth positioning hole 621 to fix the second support bar 62 on the operating surface 21. In this way, by adjusting the positions of the first support bar 61 and the second support bar 62 in the first direction X, the first support bar 61 and the second support bar 62 can better support displays of different sizes.

[0062] In one embodiment of this application, please refer to Figure 1 and Figure 3 The first support bar 61 has two sets of third positioning holes 611 spaced apart along the second direction Y, and each set of third positioning holes 611 includes multiple third positioning holes 611 spaced apart along the second direction Y. One third positioning hole 611 on each of the two sets of third positioning holes 611 is connected to one of the two third positioning holes 24. The second support bar 62 has two sets of fourth positioning holes 621 spaced apart along the second direction Y, and each set of fourth positioning holes 621 includes multiple fourth positioning holes 621 spaced apart along the second direction Y. One fourth positioning hole 621 on each of the two sets of fourth positioning holes 621 is connected to one of the two fourth positioning holes 25.

[0063] By setting two third strip holes 24 and two fourth strip holes 25, the first support bar 61 and the second support bar 62 are fixed respectively, which effectively improves the stability of the first support bar 61 and the second support bar 62 fixed on the operating surface 21. The third positioning hole 611 group of the first support bar 61 includes a plurality of third positioning holes 611 spaced apart along the second direction Y, and the fourth positioning hole 621 group of the second support bar 62 includes a plurality of fourth positioning holes 621 spaced apart along the second direction Y, so that the first support bar 61 and the second support bar 62 can drive the corresponding stop bar 70 to move along the second direction Y, thereby adjusting the position of the stop bar 70 on the operating surface 21 to adapt to different types of displays.

[0064] Optionally, the stop bar 70 and the support bar 60 are integrally formed.

[0065] By integrally molding the stop bar 70 and the support bar 60, the stability of the connection between the stop bar 70 and the support bar 60 is effectively guaranteed, and the process is simple, which helps to reduce production costs.

[0066] In one embodiment of this application, please refer to Figure 3 The first fastener 80, the second fastener 90, the third fastener 100, and the fourth fastener 110 are all butterfly screws, and the first positioning hole 31, the second positioning hole 41, the third positioning hole 611, and the fourth positioning hole 621 are all threaded holes. The first fastener 80 is inserted into the first strip hole 22 and the first positioning hole 31 from the side of the operating table 20 away from the operating surface 21, and is threaded into the first positioning hole 31 to fix the first positioning strip 30 to the operating surface 21. The second fastener 90 is inserted into the second strip hole 23 and the second positioning hole 41 from the side of the operating table 20 away from the operating surface 21, and is threaded into the second positioning hole 41 to fix the second positioning strip 40 to the operating surface 21. The third fastener 100 is inserted into the third strip hole 24 and the third positioning hole 611 from the side of the operating table 20 away from the operating surface 21, and is threaded into the third positioning hole 611 to fix the first support strip 61 to the operating surface 21. The fourth fastener 110 is inserted into the fourth strip hole 25 and the fourth positioning hole 621 from the side of the operating table 20 away from the operating surface 21, and is threadedly connected to the fourth positioning hole 621 to fix the second support bar 62 on the operating surface 21.

[0067] By using butterfly screws for the first fastener 80, the second fastener 90, the third fastener 100, and the fourth fastener 110, no additional tools are needed when installing or removing the butterfly screws, making the operation convenient and saving time spent adjusting the first positioning strip 30, the second positioning strip 40, and the support strip 60, thereby improving the efficiency of the display screen lighting test.

[0068] Of course, in other embodiments, the first fastener 80, the second fastener 90, the third fastener 100 and the fourth fastener 110 may also be hexagonal screws or the like.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
