Technical Field
[0001] This utility model relates to the field of LED screen installation technology, and in particular to an LED screen installation positioning device. Background Technology
[0002] An LED screen is a display device that uses LED technology as its light source and is widely used in advertising, public information display, stage performances, stadiums, traffic signs, and other fields. An LED screen installation and positioning device is a piece of equipment used to install and position LED screens, primarily to ensure accurate positioning, flatness, and safety of the screen during installation.
[0003] Existing technologies, such as the utility model with publication number CN220623349U, disclose an LED screen mounting structure including a connecting frame and a limiting device. A display screen is mounted on the surface of the connecting frame, a support rod is fixedly connected to the side of the connecting frame, a connecting plate is fixedly connected to the lower surface of the support rod, and a connecting rod is mounted on the lower surface of the connecting plate. The limiting device is disposed on the surface of the connecting frame and includes a sliding groove and a locking slot. The sliding groove is formed on the surface of the connecting frame, and the locking slot is formed on the surface of the display screen. A slider is slidably connected to the inner wall of the sliding groove. This utility model, by setting a limiting device, effectively restricts the display screen, reducing the need for welding between the display screen and the connecting frame during use, which can hinder quick installation and disassembly by the user, thus improving the practicality of the equipment.
[0004] During the installation of LED screens, it was found that some LED screens are quite heavy, making installation time-consuming and labor-intensive, and prone to instability, which can lead to the LED screen falling and causing safety accidents. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the large weight of certain LED screens, which makes installation time-consuming and laborious, and the tendency for unstable installation to cause the LED screen to fall, thus leading to safety accidents.
[0006] To solve the above-mentioned technical problems, this utility model provides an LED screen installation and positioning device, including: an LED screen body, a wall surface, and an installation device. The LED screen body is fixedly connected to the wall surface by means of the installation device. The installation device includes two fixing plates and a fixing frame. One side of the fixing plate is fixedly connected to the LED screen body, and a guide block is fixedly connected to the other side of the fixing plate. Two connecting blocks are fixedly connected to one side of the fixing frame. The inner wall of the connecting block is inserted into the surface of the guide block. A limit block is slidably connected to the surface of the connecting block. One end of the limit block abuts against one side of the fixing plate. A limit hole is formed on the surface of the limit block, and a screw is threadedly connected to the inner wall of the limit hole. A connecting block has an insertion hole at the position corresponding to the screw, and the inner wall of the insertion hole is threaded to the screw. A connecting block is fixedly connected to one side of the limiting block, and a slider is fixedly connected to the lower surface of the connecting block. A sliding groove is provided at the position corresponding to the slider of the fixing frame, and the inner wall of the sliding groove is slidably connected to the surface of the slider. The same lead screw is rotatably connected to both sides of the inner wall of the sliding groove, and the arc surface of the lead screw is threaded to the slider. A first bevel gear is fixedly connected to the arc surface of one end of the lead screw, and a second bevel gear meshes with the tooth surface of the first bevel gear. A rotating rod is fixedly connected to the upper surface of the second bevel gear, and a support block is rotatably connected to the arc surface of the rotating rod. One side of the two support blocks is fixedly connected to the same wall.
[0007] The effect achieved by the above components is as follows: When it is necessary to install and position the LED screen body, first turn out the two screws, then rotate the two rotating rods to make the second bevel gear rotate with the first bevel gear. The lead screw follows the second bevel gear to rotate, causing the slider to move along the slide groove and slide the limiting block on the surface of the connecting block until the guide block on the LED screen body can be inserted into the inner wall of the connecting block. Then, insert the guide block on the LED screen body into the inner wall of the connecting block so that the upper end of the guide block is flush with the upper end of the connecting block. Then, rotate the rotating rod in the opposite direction to make the limiting block slide in the opposite direction until it abuts against the fixing plate. At this time, the upper surface of the guide block abuts against the limiting block, and the limiting hole aligns with the insertion hole. Then, insert the screw. This achieves the effect of installing and positioning the LED screen body.
[0008] Preferably, one end of the rotating rod is fixedly connected to a handle, and the arc surface of the handle is provided with a plurality of anti-slip textures.
[0009] The effect achieved by the above components is that the anti-slip texture increases friction, making it easier to turn the lever with the handle.
[0010] Preferably, a support frame is fixedly connected to both sides of the lower end of the wall, and one side of the two support frames abuts against the same LED screen body.
[0011] The effect achieved by the above components is that the support frame further supports the LED screen body and prevents the LED screen body from falling.
[0012] Preferably, the support frame is fixedly connected with an elastic pad at the position corresponding to the LED screen body, and the elastic pad is a rubber pad.
[0013] The effect achieved by the above components is that the rubber pad has good elasticity, preventing the LED screen body from being damaged when the support frame comes into contact with it.
[0014] Preferably, protective devices are provided on both sides of the LED screen body. The protective devices include a protective shell located on one side of the LED screen body. Two extrusion rods slide through one side of the protective shell. A fixing block is fixedly connected to one end of the extrusion rod. A spring is sleeved on the arc surface of the extrusion rod. The two ends of the spring are fixedly connected to the protective shell and the fixing block, respectively. An auxiliary block is fixedly connected to one end of the extrusion rod. The auxiliary block is a silicone block. One side of the two auxiliary blocks abuts against the same LED screen body.
[0015] The effect achieved by the above components is as follows: the four corners of the LED screen body are easily bumped and damaged, so they need to be protected. Protective devices are installed on both sides of the LED screen body. So first pull the two fixing blocks, then install the protective shell on one side of the LED screen body. Release the fixing blocks, and under the action of the spring, the fixing blocks slide towards the LED screen body with the pressing rod, so that the auxiliary block presses the LED screen body. In this way, the protective shell is installed. Then install the other protective device. This can prevent the LED screen body from being bumped and damaged.
[0016] Preferably, the same connecting plate is fixedly connected to one side of the two fixing blocks, and a fixing column is fixedly connected to one side of the connecting plate.
[0017] The effect achieved by the above components is that the fixed column can be pulled to pull the two fixed blocks, causing the two compression rods to slide, thus achieving a more convenient function.
[0018] Preferably, a pull ring is fixedly connected to one end of the fixed column, and the pull ring has a circular cross-section.
[0019] The effect achieved by the above components is that the fixed column can be pulled by the pull ring, causing the two compression rods to slide, thus making the operation more convenient.
[0020] Compared with related technologies, the LED screen mounting and positioning device provided by this utility model has the following advantages: When positioning the LED screen body, first unscrew the two screws. Then, using the handle, rotate the two rotating rods to make the second bevel gear rotate, causing the first bevel gear to rotate as well. The lead screw follows the second bevel gear, moving the slider along the groove and sliding the limiting block on the surface of the connecting block until the guide block on the LED screen body can be inserted into the inner wall of the connecting block. Then, insert the guide block into the inner wall of the connecting block, making the upper end of the guide block flush with the upper end of the connecting block. At the same time, the lower end of the LED screen body abuts against the elastic pads on the two support frames, supporting the LED screen body. Then, using the handle, rotate the rotating rod in the opposite direction to make the limiting block slide in the opposite direction to the position abutting against the fixing plate. At this time, the upper surface of the guide block abuts against the limiting block, and the limiting hole aligns with the insertion hole. Then, insert the screws. In this way, the LED screen body is installed and positioned. By operating the installation device, the installation effect of the LED screen body is achieved.
[0021] When protection is needed for the four corners of an LED screen, protective devices must be installed on both sides of the screen. First, using the pull ring to fix the posts, the connecting plate is moved, pulling the two fixing blocks and sliding the pressing rod. Then, the protective shell is installed on one side of the LED screen. Releasing the pull ring allows the spring to cause the fixing block, along with the pressing rod, to slide towards the LED screen, causing the auxiliary block to press against the screen. This installs the protective shell. Then, the other protective device is installed. This process prevents damage to the LED screen from impacts. By operating the protective devices, the four corners of the LED screen are effectively protected. Attached Figure Description

[0026] Please see Figures 1 to 6 The present invention provides an LED screen installation and positioning device, comprising: an LED screen body 1, a wall 2 and an installation device 3. The LED screen body 1 is fixedly connected to the wall 2 by means of the installation device 3, and protective devices 4 are provided on both sides of the LED screen body 1. In the embodiments of this utility model, please refer to Figures 2 to 5The mounting device 3 includes two fixing plates 301 and a fixing frame 310. One side of the fixing plate 301 is fixedly connected to the LED screen body 1, and the other side of the fixing plate 301 is fixedly connected to a guide block 302. One side of the fixing frame 310 is fixedly connected to two connecting blocks 303. The inner wall of the connecting block 303 is inserted into the surface of the guide block 302. A limit block 306 is slidably connected to the surface of the connecting block 303. One end of the limit block 306 abuts against one side of the fixing plate 301. A limit hole 307 is formed on the surface of the limit block 306. A screw 305 is threadedly connected to the inner wall of the limit hole 307. An insertion hole 304 is formed on the connecting block 303 at the position corresponding to the screw 305. The inner wall of the insertion hole 304 is threadedly connected to the screw 305. A connecting block 308 is fixedly connected to one side of 6. A slider 309 is fixedly connected to the lower surface of the connecting block 308. A groove 311 is provided on the fixing frame 310 corresponding to the position of the slider 309. The inner wall of the groove 311 is slidably connected to the surface of the slider 309. The same lead screw 312 is rotatably connected to both sides of the inner wall of the groove 311. The arc surface of the lead screw 312 is threadedly connected to the slider 309. A first bevel gear 313 is fixedly connected to the arc surface of one end of the lead screw 312. A second bevel gear 314 meshes with the tooth surface of the first bevel gear 313. A rotating rod 315 is fixedly connected to the upper surface of the second bevel gear 314. A support block 316 is rotatably connected to the arc surface of the rotating rod 315. One side of the two support blocks 316 is fixedly connected to the same wall 2. When it is necessary to install and position the LED screen body 1, first turn out the two screws 305, then rotate the two rotating rods 315, so that the second bevel gear 314 drives the first bevel gear 313 to rotate, and the lead screw 312 follows the second bevel gear 314 to rotate, so that the slider 309 moves along the slide groove 311, and slides the limiting block 306 on the surface of the connecting block 303 until the guide block 302 on the LED screen body 1 can be inserted into the inner wall of the connecting block 303. Then insert the guide block 302 on the LED screen body 1 into the inner wall of the connecting block 303, so that the upper end of the guide block 302 is flush with the upper end of the connecting block 303. Then rotate the rotating rod 315 in the opposite direction, so that the limiting block 306 slides in the opposite direction to abut against the fixing plate 301. At this time, the upper surface of the guide block 302 abuts against the limiting block 306, and the limiting hole 307 is aligned with the insertion hole 304. Then insert the screw 305, so as to achieve the effect of installing and positioning the LED screen body 1. A handle 317 is fixedly connected to one end of the rotating rod 315. Several anti-slip textures are formed on the arc surface of the handle 317. These textures increase friction, making it easier to rotate the rod 315 using the handle 317. Support brackets 318 are fixedly connected to both sides of the lower end of the wall 2. One side of each support bracket 318 abuts against the same LED screen body 1.

The rubber pad has good elasticity to prevent the LED screen body 1 from being damaged when the support frame 318 comes into contact with it. In the embodiments of this utility model, please refer to Figure 2 and Figure 6 The protective device 4 includes a protective shell 41, which is located on one side of the LED screen body 1. Two extrusion rods 42 slide through one side of the protective shell 41. One end of the extrusion rod 42 is fixedly connected to a fixing block 43. A spring 44 is sleeved on the arc surface of the extrusion rod 42. The two ends of the spring 44 are fixedly connected to the protective shell 41 and the fixing block 43 respectively. One end of the extrusion rod 42 is fixedly connected to an auxiliary block 45, which is a silicone block. One side of the two auxiliary blocks 45 abuts against the same LED screen body 1. The four corners of the LED screen body 1 are easily damaged by bumps, so protection is needed. Protective devices 4 are installed on both sides of the LED screen body 1. First, pull the two fixing blocks 43, then install the protective shell 41 on one side of the LED screen body 1. Release the fixing blocks 43, and under the action of the spring 44, the fixing blocks 43 slide towards the LED screen body 1 along with the pressing rod 42, causing the auxiliary block 45 to press against the LED screen body 1. This installs the protective shell 41. Then, install the other protective device 4. This prevents the LED screen body 1 from being damaged by bumps. A connecting plate 46 is fixedly connected to one side of the two fixing blocks 43, and a fixing post 47 is fixedly connected to one side of the connecting plate 46. Pulling the fixing post 47 moves the two fixing blocks 43, causing the two pressing rods 42 to slide, making operation more convenient. A pull ring 48 with a circular cross-section is fixedly connected to one end of the fixing post 47. The pull ring 48 can be used to pull the fixing post 47, causing the two pressing rods 42 to slide, making operation more convenient. The working principle of the LED screen installation and positioning device provided by this utility model is as follows: When it is necessary to install and position the LED screen body 1, first turn out the two screws 305, and then rotate the two rotating rods 315 with the help of the handle 317, so that the second bevel gear 314 drives the first bevel gear 313 to rotate, and the lead screw 312 follows the second bevel gear 314 to rotate, so that the slider 309 moves along the slide groove 311, and slides the limiting block 306 on the surface of the connecting block 303 until the guide block 302 on the LED screen body 1 can be inserted into the inner wall of the connecting block 303. Then, the LED screen body 1 is installed and positioned. The guide block 302 is inserted into the inner wall of the connecting block 303, so that the upper end of the guide block 302 is flush with the upper end of the connecting block 303. At the same time, the lower end of the LED screen body 1 abuts against the elastic pads 319 on the two support brackets 318, supporting the LED screen body 1. Then, with the help of the handle 317, the rotating rod 315 is rotated in the opposite direction, so that the limiting block 306 slides in the opposite direction to the position abutting against the fixing plate 301. At this time, the upper surface of the guide block 302 abuts against the limiting block 306, and the limiting hole 307 is aligned with the insertion hole 304. Then, the screw 305 is inserted, and the LED screen body 1 is installed and positioned.
[0027] When it is necessary to protect the four corners of the LED screen body 1, protective devices 4 need to be installed on both sides of the LED screen body 1. So, first, use the pull ring 48 to fix the post 47, so that the connecting plate 46 can be moved. In this way, the two fixing blocks 43 are pulled and the pressing rod 42 slides. Then, the protective shell 41 is installed on one side of the LED screen body 1. Release the pull ring 48, and under the action of the spring 44, the fixing block 43 slides towards the LED screen body 1 with the pressing rod 42, so that the auxiliary block 45 presses the LED screen body 1. In this way, the protective shell 41 is installed. Then, the other protective device 4 is installed. This can prevent the LED screen body 1 from being damaged by bumps.
