[0003] The existing wall-mounted multi-functional advertising machine device with LCD splicing screen has the following technical problems when used: 1. Wall-mounted equipment usually needs to withstand heavy loads. If the bracket or cabinet is not designed with sufficient strength, it may deform or loosen. After long-term use, the connecting parts (such as screws and brackets) are prone to oxidation or loosening, which may cause the screen to shake or shift position. 2. The wall-mounted multi-functional advertising machine of the LCD splicing screen adopts a bare screen design (without a dust cover or protective frame). During placement, dust accumulation may occur, which may lead to interface oxidation or poor heat dissipation of internal components. Utility Model Content

[0004] The purpose of this invention is to solve the problem that after long-term use, the connecting parts are prone to oxidation or loosening, which leads to screen shaking or positional displacement. Therefore, this invention proposes a wall-mounted multi-functional advertising machine device for LCD splicing screens.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a wall-mounted multi-functional advertising machine device for LCD video wall, including LCD video wall and a first bracket, wherein the back of the LCD video wall is fixedly connected to the first bracket, and a connecting mechanism is provided on the outside of the first bracket. The connecting mechanism includes a second bracket, a support column, a first support rod, a support plate, and a support plate; The end of the second bracket is fixedly connected to the first bracket. The second bracket is fixedly connected to the back of the LCD splicing screen. Both the second bracket and the first bracket are fixedly connected to the outside of the support column. The ends of the multiple support columns are fixedly connected to the support plate. The upper ends of the multiple first support rods are fixedly connected to the first bracket by bolts. The other ends of the multiple first support rods are fixedly connected to the support plate. The upper surface of the support plate is in contact with the LCD splicing screen.

[0006] Preferably, a shielding mechanism is provided above the first bracket; The shielding mechanism includes a second support rod, a frame, a roller, a rotating wheel, and a shielding cloth; Multiple second support rods are fixed to the upper surface of the first bracket by bolts. Multiple second support rods are fixedly connected to the outer wall of the frame. The inside of the frame is rotatably connected to a roller through a damping shaft. Both ends of the roller are fixedly connected to a wheel. The outer wall of the roller is wrapped with a shielding cloth.

[0007] Preferably, a slider is fixedly connected to the back of the support plate, the slider has multiple slots inside, and the outer wall of the slider is slidably connected to the slide rail.

[0008] Preferably, a back plate is fixedly connected to the back of the slide.

[0009] Preferably, the back plate has multiple through holes inside.

[0010] Preferably, a slide rod is slidably connected inside the slide rail, one end of the slide rod is engaged with a slot provided inside the slider, and the other end of the slide rod is fixedly connected with a pull ring.

[0011] Preferably, a spring is fitted onto the outer wall of the slide rod.

[0012] Preferably, the two ends of the spring are fixedly connected to the slide rod and the slide rail, respectively.

[0013] This utility model proposes a wall-mounted multi-functional advertising machine device for LCD video walls. The advantages are as follows: Through the cooperation of the second bracket, the support column, the first support rod, the support plate, and the support plate, multiple first support rods are bolted to the bottom of the first bracket. These first support rods support and position the support plate. The support plate fits against the lower end of the LCD video wall, supporting it and ensuring that the weight of the LCD video wall is entirely distributed on the first and second brackets. Both the first and second brackets are connected to the support plate via the support column. The position of the support plate relative to the LCD video wall is relatively fixed. The back plate has multiple through holes, increasing the number of fasteners and enhancing the stability of the back plate and its installation position. The second bracket increases the stability of the first bracket, preventing deformation. The support plate supports the LCD video wall, preventing deformation or loosening. After long-term use, the connecting parts are less likely to loosen, avoiding screen shaking or positional shift.

[0014] Through the cooperation of the second support rod, frame, roller, turntable, and shielding cloth, the wall-mounted multi-functional advertising machine of the LCD video wall unit operates by rotating the turntable, which drives the roller to rotate. The roller rolls up the shielding cloth, ensuring that the protruding end of the shielding cloth is higher than the LCD video wall and does not affect its use. When rotating the turntable, the shielding cloth is prevented from being completely retracted into the frame for use. After use, the turntable is rotated in the opposite direction, and the roller releases the shielding cloth, which then shields the front of the LCD video wall to prevent dust accumulation during placement, which could lead to interface oxidation or poor heat dissipation of internal components.

[0018] A shielding mechanism 4 is provided above the first support 2. The shielding mechanism 4 includes second support rods 401, a frame 402, a roller 403, a rotating wheel 404, and a shielding cloth 405. Multiple second support rods 401 are bolted to the upper surface of the first support 2. The positions of the multiple second support rods 401 relative to the first support 2 are fixed. The multiple second support rods 401 are also fixedly connected to the outer wall of the frame 402. The multiple second support rods 401 support and position the frame 402. The frame 402 is relatively fixed in position. Inside the frame 402, a roller 403 is rotatably connected via a damping shaft. The roller 403 does not rotate due to inertia inside the frame 402. Both ends of the roller 403 are fixed with a rotating wheel 404, which drives the roller 403 to rotate. A shielding cloth 405 is wrapped around the outer wall of the roller 403. The roller 403 retracts and expands the shielding cloth 405. One end of the shielding cloth 405 is fixed to the outer wall of the roller 403, and the other end extends to the outside of the frame 402. When using the wall-mounted multi-functional advertising machine for the LCD video wall, rotate the rotating wheel 404 (either one side or both sides can be rotated simultaneously; if rotating one side is too strenuous, two people can rotate both rotating wheels 404 simultaneously). The rotating wheel 404 drives the roller 403 to rotate, and the roller 403 rolls up the shielding cloth 405 so that the protruding end of the shielding cloth 405 is higher than the LCD video wall 1 and does not affect the use of the LCD video wall 1. When rotating the rotating wheel 404, avoid the shielding cloth 405 being completely retracted into the frame 402 for use on the LCD video wall 1. After use, rotate the rotating wheel 405 in the opposite direction, and the roller 403 releases the shielding cloth 405. The shielding cloth 405 covers the front of the LCD video wall 1 to prevent dust accumulation during placement, which may lead to oxidation of the interface or poor heat dissipation of internal components.

[0019] A slider 5 is fixedly connected to the back of the support plate 305. The support plate 305 and the slider 5 move together. The slider 5 has multiple slots inside. The outer wall of the slider 5 is slidably connected to the slide rail 6. The slider 5 slides inside the slide rail 6. A back plate 7 is fixedly connected to the back of the slide rail 6.

One end of the slide rod 9 is engaged with the slot in the slider 5. The slide rod 5 is inserted into the slot in the slider 5 to fix the relative positions of the slider 5 and the slide rail 6. A pull ring is fixedly connected to the other end of the slide rod 9. The pull ring facilitates the pulling of the slide rod 9. A spring 10 is sleeved on the outer wall of the slide rod 9. The model of the spring 10 is selected according to the actual use requirements to meet the working requirements. The two ends of the spring 10 are fixedly connected to the slide rod 9 and the slide rail 6 respectively. The spring 10 can drive the slide rod 9 to move under the elastic action. The first bracket 2 is relatively fixed in position to the LCD video wall 1. The second bracket 301 is fixed inside the first bracket 2 to increase its strength and prevent deformation. Multiple first support rods 303 are bolted to the bottom of the first bracket 2, supporting and positioning the support plate 304. The support plate 304 is in contact with the lower end of the LCD video wall 1, supporting it and ensuring the weight of the LCD video wall 1 is entirely distributed on the first bracket 2 and the second bracket 301. Both the first bracket 2 and the second bracket 301 are connected to the support plate 305 via pillars 302. The support plate 305 is relatively fixed in position to the LCD video wall 1. The back plate 7 is attached to the desired installation location. A fastener is passed through the through hole 8 to install and fix the back plate 7 in the desired position, thus installing the LCD video wall 1. Pulling the pin 9... The pin 9 slides inside the slide rail 6 and compresses the spring 10. The end of the pin 9 separates from the slot provided in the slider 5. The slider 5 slides inside the slide rail 6, thereby changing the height of the LCD video wall 1 and placing it at the required height. The pin 9 is released, and the spring 10 drives the pin 9 to slide in the opposite direction under the elastic action. The pin 9 is inserted into the corresponding slot in the slider 5, fixing the position of the slider 5 relative to the slide rail 6, thus completing the height adjustment of the LCD video wall 1. The back plate 7 has multiple through holes 8 inside, which can increase the number of fasteners and increase the stability of the back plate 7 and the installation position. The second bracket 301 increases the stability of the first bracket 2 and reduces the deformation of the first bracket 2. The support plate 304 supports the LCD video wall 1 and will not deform or loosen. After long-term use, the connecting parts are not easy to loosen, avoiding screen shaking or position displacement.

[0020] Working principle: When using the wall-mounted multi-functional advertising machine device with an LCD video wall, the position of the first bracket 2 and the LCD video wall 1 is relatively fixed. The second bracket 301 is fixed inside the first bracket 2 to increase the strength of the first bracket 2 and prevent deformation. Multiple first support rods 303 are bolted to the bottom of the first bracket 2, supporting and positioning the support plate 304. The support plate 304 is attached to the lower end of the LCD video wall 1, supporting it and ensuring that the weight of the LCD video wall 1 is entirely distributed on the first bracket 2 and the second bracket 301. Both the first bracket 2 and the second bracket 301 are connected to the support plate 305 via pillars 302. The support plate 305 is relatively fixed to the position of the LCD video wall 1. The back plate 7 is attached to the location where it needs to be installed and fixed. A fastener is passed through the through hole 8 to install and fix the back plate 7 in the required position, thus securing the LCD video wall 1. Pull the pin 9, and the pin 9 slides inside the slide rail 6, compressing the spring 10. The end of the pin 9 separates from the slot provided in the slider 5. Slide the slider 5, and the slider 5 slides inside the slide rail 6, thereby changing the height of the LCD splicing screen 1 to the required height. Release the pin 9, and the spring 10 drives the pin 9 to slide in the opposite direction under the elastic action. The pin 9 is inserted into the corresponding slot in the slider 5, fixing the position of the slider 5 and the slide rail 6, thus completing the height adjustment of the LCD splicing screen 1. The back plate 7 has multiple through holes 8 inside, which can increase the number of fasteners and increase the stability of the back plate 7 and the installation position. The second bracket 301 increases the stability of the first bracket 2 and reduces the deformation of the first bracket 2. The support plate 304 supports the LCD splicing screen 1 and will not deform or loosen. After long-term use, the connecting parts are not easy to loosen, avoiding screen shaking or position displacement. Occlusion phase: When using the wall-mounted multi-functional advertising machine for LCD video walls, rotate the wheel 404 (either one or both sides can be rotated simultaneously; if rotating one side is too strenuous, two people can rotate both wheels 404 simultaneously). The wheel 404 drives the roller 403 to rotate, and the roller 403 rolls up the covering cloth 405 so that the protruding end of the covering cloth 405 is higher than the LCD video wall 1 and does not affect the use of the LCD video wall 1. When rotating the wheel 404, avoid the covering cloth 405 being completely retracted into the frame 402 for use on the LCD video wall 1. After use, rotate the wheel 405 in the opposite direction, and the roller 403 releases the covering cloth 405. The covering cloth 405 covers the front of the LCD video wall 1 to prevent dust accumulation during placement, which may cause oxidation of the interface or poor heat dissipation of internal components. The height of the LCD video wall 1 can be adjusted, and after use, the covering cloth covers the surface of the LCD video wall 1, thus realizing the wall-mounted multi-functional advertising machine device for LCD video walls.
