Detailed implementation manners

[0023] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] A modular OLED display screen, referring to Figures 1-6 as shown, includes a frame 1, a support plate 2, a display screen body 3, a push plate 4, a pressure plate 5, a bump 6, a clamping plate 7 and an elastic member 8. A plurality of support plates 2 are provided on the frame 1 by means of bolt connection, and the plurality of support plates 2 are evenly spaced on the frame 1. Two push plates 4 are provided on the display screen body 3 by means of bolt connection, and the two push plates 4 are symmetric left and right. A pressure plate 5 is provided on the push plate 4 by means of bolt connection. A plurality of bumps 6 are provided on the support plate 2 by means of welding, and the plurality of bumps 6 are evenly spaced on the support plate 2. The pressure plate 5 is docked with the bump 6. Two clamping plates 7 are slidably arranged inside the bump 6, and the two clamping plates 7 are symmetric left and right. The clamping plate 7 contacts the pressure plate 5. An elastic member 8 is commonly connected to the clamping plate 7 and the bump 6. It further includes a cleaning mechanism 13, and a cleaning mechanism 13 for wiping the display screen body 3 is provided on the frame 1.

[0026] Referring to Figure 1 and Figure 6As shown in the figure, the cleaning mechanism 13 includes a support frame 1301, a motor 1302, a threaded rod 1304, a guide plate 1303, a fixing plate 1305 and a sponge pad 1306. The support frame 1301 is provided on the frame 1 by means of bolt connection. The motor 1302 is provided on the support frame 1301 by means of bolt connection. A threaded rod 1304 is provided on the output shaft of the motor 1302 through a coupling. Two guide plates 1303 for guiding are provided on the frame 1 by means of bolt connection. The two guide plates 1303 are symmetrically arranged up and down. The fixing plate 1305 is threadedly arranged on the threaded rod 1304. The fixing plate 1305 slides between the two guide plates 1303. The sponge pad 1306 is embedded on the fixing plate 1305. The sponge has adsorption performance and can achieve a good wiping effect.

[0027] When the OLED display screen needs to be used, the staff places the frame 1 at a suitable position on the ground, and then turns on the display screen body 3 to start playing the image. When the malfunctioning display screen body 3 needs to be replaced, the staff squeezes the clamping plate 7 inward to retract the convex block 6, and the elastic member 8 is compressed accordingly. Then, the staff moves the display screen body 3 forward to disengage the pressing plate 5 from the convex block 6, removes the display screen body 3 from the support plate 2, places the new display screen body 3 in the frame 1, and makes the pressing plate 5 dock with the convex block 6. The staff releases the clamping plate 7, and the elastic member 8 returns to its original state, causing the clamping plate 7 to pop out of the convex block 6 and contact the pressing plate 5, thereby fixing the display screen body 3 on the support plate 2, so as to achieve the purpose of quickly replacing the display screen body 3. When the display screen body 3 starts to play the image, external dust and other impurities will adhere to the surface of the display screen body 3. The staff turns on the motor 1302, and the rotation of the output shaft of the motor 1302 drives the threaded rod 1304 to rotate, thereby driving the fixing plate 1305 to drive the sponge pad 1306 to move to the right, and then wiping the dust and other impurities on the surface of the display screen body 3, avoiding excessive dust and other impurities adhering to the surface of the display screen body 3 and affecting the playing effect. When the sponge pad 1306 moves to a suitable position to the right, the staff turns off the motor 1302.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, referring to Figure 5 As shown in the figure, it further includes a bidirectional screw 10, a connecting plate 11 and an adjusting plate 12. The bidirectional screw 10 is rotatably arranged on the frame 1. Two connecting plates 11 are slidably arranged on the bidirectional screw 10. The connecting plates 11 slide on the frame 1. An adjusting plate 12 for adjusting the internal space of the frame 1 is provided on the connecting plate 11 by means of bolt connection.

[0030] Referring to Figure 5As shown in the figure, it further includes a knob 9. The knob 9 for assisting rotation is arranged on the bidirectional screw rod 10 by welding. The knob 9 increases the contact area between the staff's hand and the bidirectional screw rod 10, facilitating the rotation of the bidirectional screw rod 10.

[0031] Refer to Figure 5 As shown in the figure, it further includes a protective pad 18. Two protective pads 18 for protection are embedded on the frame 1. The protective pad 18 is made of rubber, and the rubber texture is soft, which can achieve a good protection effect.

[0032] When the adjusting plate 12 contacts the frame 1, the protective pad 18 plays a protective role to prevent the adjusting plate 12 from wearing the frame 1. When it is necessary to adjust the size of the OLED display screen, the staff removes all the display screen bodies 3 from the support plate 2, and then holds the knob 9 by hand to rotate the bidirectional screw rod 10, so that the connecting plate 11 drives the adjusting plate 12 to move inwards to a proper position, thereby achieving the purpose of adjusting the installation space of the frame 1 and facilitating fixing an appropriate number of display screen bodies 3 on the support plate 2 to form an OLED display screen with a proper size.

[0033] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
