Description

Technical Field

[0001] The present invention relates to the field of display screens, and in particular to a display screen. Background Art

[0002] In the field of display screens (such as LED display screens), existing large-sized display screens are mostly assembled by splicing at least two display modules. At present, due to the imperfect encapsulation technology of lamp beads and the imperfect subsequent manufacturing processes such as chip mounting in this industry, the quality of display modules is unstable, and the defective display modules need to be replaced.

[0003] Currently, the commonly used fixing methods for display modules are screw fixing or magnet adsorption fixing. These two fixing methods have their own advantages and disadvantages; the display module fixed by screws is relatively firm, but it is inconvenient for maintenance and replacement; although the magnet adsorption method can quickly remove the display module without removing screws, this adsorption method cannot resist wind resistance, and the display module is likely to fall off in windy conditions. Some manufacturers in the industry add a safety rope behind the display module, but this only serves as an insurance and affects the appearance. Summary of the Invention

[0032] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0033] Please refer to Figures 1 to 5, an embodiment of the present invention discloses a display screen 100, which includes a display screen frame 10, a display module 20 detachably connected to the display screen frame 10, and a locking mechanism 30 installed on the back of the display module 20 for locking the display module 20 on the display screen frame 10. The display screen frame 10 has at least two frame bars 11 arranged in a row and spaced apart from each other. At least two card slots 111 arranged at intervals and opposite to each other are provided on any two adjacent frame bars 11. The locking mechanism 30 includes two telescopic rods 31 and a driving component 32 for driving the two telescopic rods 31 to be inserted into the card slots 111 provided on the two frame bars 11 or pulled out from the card slots 111 provided on the two frame bars 11. The driving component 32 is installed on the back of the display module 20 and connected to the two telescopic rods 31.

[0034] In this design, by providing a locking mechanism 30 on the back of the display module 20, and by providing that the locking mechanism 30 includes two telescopic rods 31 and a driving component 32, the driving component 32 is arranged on the back of the display module 20 and connected to the two telescopic rods 31 for driving the two telescopic rods 31 to extend into the two card slots 111 or be pulled out from the two card slots 111 respectively. In this way, when the display module 20 needs to be installed on the display screen frame 10, the user can drive the two telescopic rods 31 to be respectively clamped in the two relatively arranged card slots 111 on the display screen frame 10 through the driving component 32, so that the display module 20 can be firmly installed on the display screen frame 10 and is not easy to fall off in windy conditions. When the display module 20 needs to be disassembled from the display screen frame 10, the operator only needs to pull out the two telescopic rods 31 from the two card slots 111 through the driving component 32 and remove the display module 20. That is, in this design, the disassembly and installation of the display module 20 are very simple and can effectively improve the installation efficiency.

[0035] Please refer to Figures 6 to 10 , preferably, the driving component 32 is a knob component arranged on the back of the display module. One ends of the two telescopic rods 31 are respectively hinged to both sides of the knob component. Preferably, the knob component includes a knob 321 and an adapter 322 with one end connected to the knob 321. One ends of the two telescopic rods 31 are respectively hinged to both sides of the adapter 322.

[0036] Preferably, the adapter 322 includes a plate body 3221, a first protrusion 3222 disposed on one side of the plate body 3221, and a second protrusion 3223 disposed on the other side of the plate body 3221. The first protrusion 3222 is connected to the knob 321. A limiting hole 21 is formed in the back surface of the display module 20. The second protrusion 3223 is rotatably mounted in the limiting hole 21. One ends of the two telescopic rods 31 are respectively hinged to both sides of the plate body 3221. Specifically, a long waist-shaped hole 3211 is provided on the side of the knob 321 close to the adapter 322. The cross-sectional shape of the first protrusion 3222 is a runway shape matching the shape of the waist-shaped hole 3211. The first protrusion 3222 passes through the long waist-shaped hole 3211. It can be understood that the knob 321 and the adapter 322 can also be integrally formed. By providing that the second protrusion 3223 is rotatably mounted in the limiting hole 21, the limiting hole 21 plays a role in limiting the operation of the adapter 322, that is, the adapter 322 will not deflect left and right during the process of pulling the telescopic rod 31 to operate, but rotates smoothly and the adapter 322 is evenly stressed, which can extend the service life of the locking mechanism 30.

[0037] Preferably, on both sides of the first protrusion 3222 of the plate body 3221 and in the extending direction of the first protrusion 3222, first through holes 3224 are respectively formed through. One ends of the two telescopic rods 31 are respectively formed with second through holes 311. The locking mechanism 30 further includes two pins 33. The telescopic rod 31 is hinged to the plate body 3221 by passing the pin 33 through the first through hole 3224 and the second through hole 311. Preferably, the pin 33 includes a pin cap, a first pin rod portion and a second pin rod portion connected in sequence. The outer wall of the first pin rod portion is smooth, and the outer wall of the second pin rod portion is provided with threads. The telescopic rod 31 is sleeved outside the first pin rod portion. The first through hole 3224 is a threaded hole, and the plate body 3221 is in threaded cooperation with the second pin rod portion.

[0038] Preferably, two arc-shaped holes 22 are formed at the side of the limiting hole 21 of the display module 20 and are spaced apart in the circumferential direction. One end of each pin 33 away from the knob 321 is slidably passed through the arc-shaped hole 22. The two arc-shaped holes 22 play a role in limiting the rotation of the knob 321. The so-called sliding through here means that the part of the pin 33 passing through the arc-shaped hole 22 can slide along the track of the arc-shaped hole 22.

[0039] Preferably, each telescopic rod 31 includes a first rod portion 312 with one end that can extend into the card slot 111 and a second rod portion 313 with one end hinged to the other end of the first rod portion 312. One end of each second rod portion 313 away from the first rod portion 312 is hinged to the plate body 3221. Preferably, a notch 3121 facing the back surface of the display module 20 is provided at one end of each first rod portion 312 away from the second rod portion 313. The telescopic rod 31 is lapped in the card slot 111 of the frame strip 11 through the notch 3121.

[0040] Preferably, the locking mechanism 30 further includes a cover plate 34 mounted on the back surface of the display module 20. The cover plate 34 and the display module 20 form a receiving cavity. A knob hole 341 is formed on the side of the cover plate 34 away from the display module 20. A part of the knob 321 is installed in the receiving cavity, and the other part protrudes out of the receiving cavity through the knob hole 341. The cover plate 34 is provided with third protrusions 342 on both sides of the knob hole 341. First grooves 343 for positioning the knob 321 when the telescopic rod 31 extends into the card slot 111 are provided on the opposite surfaces of the two third protrusions 342 facing each other. Fourth protrusions 3212 for being clamped in the first grooves 343 are provided on both sides of the knob 321 facing each other. By providing the first grooves 343 on the opposite surfaces of the third protrusions 342 facing each other and the fourth protrusions 3212 for being clamped in the first grooves 343 on both sides of the knob 321 facing each other, in this way, when the locking mechanism 30 is in the locked state, the two third protrusions 342 can fix the knob 321 through the first grooves 343, preventing the knob 321 from rotating due to being touched, resulting in unlocking of the locking mechanism 30 and detachment of the display module 20.

[0041] Preferably, a second groove 231 is recessed on the back surface of the display module 20. Two convex blocks 232 for connecting with the cover plate 34 are protruded at intervals on the bottom surface of the second groove 231. The second groove 231 is divided into a first groove portion 2311 and second groove portions 2312 located on both opposite sides of the first groove portion 2311 by the two convex blocks 232. A clamping block 112 is provided on each of the two frame strips 11. The two clamping blocks 112 are partially clamped in the second groove portions 2312. The two card slots 111 are respectively provided on the two clamping blocks 112. A first through groove is recessed on the surface of the convex block 232 facing the cover plate 34. A second through groove is recessed on the surface of the cover plate 34 connected to the convex block 232. When the cover plate 34 is connected to the convex block 232, the first through groove and the second through groove enclose a through hole for the telescopic rod 31 to pass through.

[0042] Preferably, the display module 20 further includes a plurality of first magnets 25. A plurality of mounting grooves 26 for mounting the first magnets 25 are further provided on the back surface of the display module 20. A plurality of second magnets or metal parts magnetically adsorbable to the first magnets 25 are provided on the surface of the display screen frame 10 that cooperates with the display module 20. Alternatively, the display screen frame 10 is a metal frame body magnetically adsorbable to the first magnets 25. In this design, the display module 20 can be adsorbed and fixed on the display screen frame 10 through the first magnets 25. During the actual installation process, the operator first adsorbs the display module 20 on the display screen frame 10 through the first magnets 25, and then locks the display module 20 on the display screen frame 10 through the locking mechanism 30. This is not only convenient for installation but also makes the connection between the display module 20 and the display screen frame 10 firm, and the display module 20 will not fall off in windy conditions. It can be understood that it is also possible not to provide the first magnets 25, and the display module 20 is fixed on the display screen frame 10 through the locking mechanism 30.

[0043] Preferably, there are at least two display modules 20. The number of the locking mechanisms 30 is the same as the number of the display modules 20. The number of the card slots 111 is twice the number of the display modules 20. Each display module 20 is respectively locked to the display screen frame 10 through a locking mechanism 30.

[0044] Please refer to Figure 4 、 Figure 6 、 Figure 11 and Figure 12 Preferably, the display module 20 includes a module bracket 23 and a light board 24 mounted on the module bracket 23. The locking mechanism 30 is arranged on the back surface of the module bracket 23. The limiting holes 21 are formed in the module bracket 23. Hexagonal socket holes 3225 are provided on the second protrusions 3223. Disassembly holes 241 aligned with the limiting holes 21 are formed through the light board 24. By providing the hexagonal socket holes 3225, the user can use a hexagonal wrench to remove the locking mechanism 30 from the front of the light board 24, and thus can remove the display module 20 from the front of the light board 24. When it is not convenient to disassemble the display module 20 from the back during the installation of the display screen 100, the provision of the hexagonal socket holes 3225 and the disassembly holes 241 facilitates front maintenance.

[0045] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
