Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a magnetic miniLED right-angle display screen. Background Technology

[0002] MiniLED is defined as an LED device with a chip size between 50-200μm, consisting of a miniLED pixel array and driving circuitry, with a pixel pitch of 0.3-1.5mm. With the rapid development of miniLED display technology, miniLED display products have begun to be applied to ultra-large high-definition displays, such as monitoring and command centers, high-definition broadcasting, high-end cinemas, medical diagnostics, advertising displays, conference and exhibition facilities, office displays, virtual reality, and other commercial applications. MiniLED displays include various creative shapes such as wave screens, corner screens, right-angle screens, and sandwich screens.

[0003] Currently, miniLED right-angle displays are usually installed using magnetic attraction, which has the advantage of quick installation. However, the magnetic force of the magnetic stone may gradually disappear after long-term use. Once the magnetic force disappears, the display screen may fall directly, which is very dangerous. In addition, some magnetic stones have strong magnetic force, making them difficult to separate during removal. The force used may also cause impact damage to the display screen. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A magnetic miniLED right-angle display screen includes:

[0006] The display screen body and the connecting frame are provided. Four connecting rods are fixedly connected to the side wall of the display screen body. Iron blocks are fixedly installed on the inner side of each of the four connecting rods. Four recesses are opened on the side wall of the connecting frame. Push plates are slidably connected to each of the four recesses. Springs are fixedly connected to each of the four push plates and the connecting frame. Two magnetic stones are slidably connected to each of the four recesses. An auxiliary clamping structure is installed on the connecting frame. A quick disassembly structure is also installed on the connecting frame.

[0007] Preferably, the auxiliary clamping structure includes two clamping rods fixedly connected to the upper side of the push plate, eight sliding rods slidably connected to the side wall of the connecting frame, the eight sliding rods being in pairs, each of the eight sliding rods being fixedly connected to the connecting frame with a spring, a clamping ring being fixedly connected to the side wall of the sliding rod, and a fixing rod being fixedly connected to the upper side of the clamping ring, the fixing rod having a slot.

[0008] Preferably, the quick-disassembly structure includes eight locking blocks slidably connected to the side wall of the connecting frame, the eight locking blocks being in pairs, a connecting plate being fixedly connected between the locking blocks and the magnetic stone, a spring being fixedly connected between the connecting plate and the connecting frame, and four pressing plates being slidably connected to the upper side of the connecting frame.

[0009] Preferably, two reinforcing rods are fixedly connected to the side wall of the connecting frame.

[0010] Preferably, four electric fans are fixedly mounted on the side wall of one of the reinforcing rods.

[0011] Preferably, each of the four extrusion plates has a pressure block fixedly connected to its upper side.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the auxiliary clamping structure can clamp the connection of the display screen after successful installation, thereby giving the connection an additional force, which prevents the display screen from falling directly after the magnetic force of the magnetic stone disappears. In addition, the additional clamping force can also make the magnetic connection of the display screen more impact-resistant, preventing the display screen from falling directly due to excessive impact.

[0014] 2. In this utility model, the quick disassembly structure allows the two magnetic stones to move to both sides without directly connecting with the iron block, reducing the force at the magnetic attraction point and making disassembly easier, thus avoiding the situation where excessive magnetic force leads to violent disassembly.

Detailed Implementation

[0022] Reference Figures 1-6 A magnetic miniLED right-angle display screen, comprising:

[0023] The display screen body 1 and the connecting frame 2 are fixed to the wall by screws and nuts. The display screen body 1 can be mounted on the connecting frame 2. Two reinforcing rods 17 are fixedly connected to the side wall of the connecting frame 2. The two reinforcing rods 17 greatly increase the strength of the connecting frame 2, enabling it to withstand greater vibration and impact and preventing the connecting frame 2 from falling apart. Four electric fans 18 are fixedly installed on the side wall of one of the reinforcing rods 17. Each electric fan 18 consists of an electric motor and a fan. The fan is installed on the output end of the electric motor. By energizing the electric motor, the electric motor drives the fan to rotate. This is existing technology and will not be described in detail. The electric fans 18 can dissipate heat from the back of the display screen body 1 by blowing away the heat. As a result, four connecting rods 3 are fixedly connected to the side wall of the display body 1, and iron blocks 4 are fixedly installed on the inner side of each of the four connecting rods 3. The side wall of the connecting frame 2 has four notches, which match the four connecting rods 3. The four connecting rods 3 can be inserted into the four notches. Push plates 5 are slidably connected in each of the four notches. Springs 6 are fixedly connected to each of the four push plates 5 and the connecting frame 2. The insertion of the four connecting rods 3 can cause the push plates 5 to move backward, thereby compressing the springs 6. Two magnetic stones 7 are slidably connected in each of the four notches. The four connecting rods 3 drive the iron blocks 4 to move to the bottom, so that the magnetic stones 7 can attract the iron blocks 4, thereby generating a magnetic force to fix the display body 1. An auxiliary clamping structure is installed on the connecting frame 2, and a quick disassembly structure is also installed on the connecting frame 2.

[0024] The auxiliary clamping structure includes two locking rods 8 fixedly connected to the upper side of the push plate 5. Eight sliding rods 9 are slidably connected to the side wall of the connecting frame 2. The eight sliding rods 9 are in pairs. Each of the eight sliding rods 9 is fixedly connected to the connecting frame 2 with a spring 10. Clamping rings 11 are fixedly connected to the side wall of the sliding rods 9. The two clamping rings 11 match each other. One clamping ring 11 has a long insertion rod, and the other clamping ring 11 has a slot. The insertion rod can be inserted into the slot, thereby improving the clamping effect. A fixing rod 12 is fixedly connected to the upper side of the clamping ring 11. The fixing rod 12 has a slot. The locking rod 8 can be inserted into the slot to restrict the fixing rod 12, thereby preventing the clamping ring 11 from moving.

[0025] The quick-disassembly structure includes eight locking blocks 13 slidably connected to the side wall of the connecting frame 2. The eight locking blocks 13 are in pairs. The upper side of the locking blocks 13 has a sloping sliding surface. A connecting plate 14 is fixedly connected between the locking blocks 13 and the magnetic stone 7. A spring 15 is fixedly connected between the connecting plate 14 and the connecting frame 2. Four pressing plates 16 are slidably connected to the upper side of the connecting frame 2. The lower side of the pressing plates 16 has a sloping sliding surface. By moving the pressing plates 16 downward, the two locking blocks 13 can be moved to the sides respectively, thereby separating the magnetic stone 7 from the iron block 4. Each of the four pressing plates 16 has a pressure block 19 fixedly connected to its upper side. The pressure block 19 allows the operator to better control the pressing plates 16 and facilitates the movement of the pressing plates 16.

[0026] In this invention, the four connecting rods 3 are first pressed into the four recesses. The movement of the connecting rods 3 within the recesses causes the push plate 5 to move backward. When the four connecting rods 3 reach the bottom, the two magnetic stones 7 attract the iron blocks 4 on the sidewalls of the connecting rods 3, generating a strong magnetic force that allows the display screen body 1 to be fixed to the outside of the connecting frame 2. During the pushing process, the push plate 5 can move the two locking rods 8, allowing the locking rods 8 to slide out of the slots on the fixing rod 12, thus removing the restriction on the fixing rod 12. The unrestricted fixing rod 12 allows the clamping rings 11 and sliding rods 9 to move. Both sliding rods 9 move inward due to the elastic force of the spring 10, causing the two clamping rings 11 to move inward simultaneously, thereby clamping the connecting rods 3. The additional clamping force provides extra force to the connection point, preventing the display screen 1 from falling directly after the magnetic force of the magnetic stone 7 disappears. Furthermore, the extra clamping force strengthens the impact resistance of the magnetic connection point of the display screen 1, preventing excessive impact from causing the display screen to detach. When disassembly is required, the pressure block 19 and the squeezing plate 16 press downwards, causing the inclined sliding surface on the lower side of the squeezing plate 16 to press against the inclined sliding surface on the upper side of the two locking blocks 13. This causes the two locking blocks 13 to move to both sides. The movement of the locking blocks 13, through the connecting plate 14, moves the magnetic stone 7, separating it from the iron block 4. This avoids the difficulty of pulling it out directly, making disassembly more convenient, time-saving, and labor-saving, and preventing damage to the display screen 1 from forceful removal.
