Technical Field
[0001] This utility model relates to the field of LED display technology, specifically to a dustproof and heat dissipation device for LED displays. Background Technology
[0002] In today's rapidly developing information society, outdoor LED displays have expanded from commercial applications such as public information display to consumer multimedia applications, and can now be seen in suburbs and along major highways.
[0003] Publication No. CN208300205U discloses a heat dissipation device for LED displays. It involves fixing a heat dissipation box to one end of a frame, connecting a dustproof frame to one end of the heat dissipation box, and evenly distributing baffles on the inner side of the dustproof frame. A dustproof mesh is installed on the side of the baffles closest to the heat dissipation box to prevent dust from entering the heat dissipation box, thus providing a certain degree of dust prevention. However, this patent still has the following problems in practical use:
[0004] By fixing a heat sink to one end of a frame and connecting a dustproof frame to the other end of the heat sink, and evenly placing baffles on the inner side of the dustproof frame, with a dustproof net on the side of the baffles closest to the heat sink, dust can be prevented from entering the heat sink, thus providing a certain dustproof effect. However, after use, the dust on the dustproof net needs to be cleaned periodically. Cleaning the dustproof net usually involves disassembling it, and since the dustproof net is mostly installed using bolts, it is inconvenient to disassemble or install it.
[0005] A dustproof and heat dissipation device for LED displays is proposed to address the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a dustproof and heat dissipation device for LED displays, in order to solve the problem mentioned in the background art. Currently, the heat dissipation box is fixedly connected to one end of the frame, and a dustproof frame is connected to one end of the heat dissipation box. Baffles are evenly arranged on the inner side of the dustproof frame, and a dustproof net is set on the side of the baffles near the heat dissipation box. This helps to prevent dust from entering the heat dissipation box and has a certain dustproof effect. However, after the dustproof net is used, the dust on the dustproof net needs to be cleaned irregularly. When cleaning the dustproof net, it is mostly done by disassembling the dustproof net for cleaning. However, the dustproof net is mostly installed by bolts, which makes it inconvenient to disassemble or install the dustproof net.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dustproof and heat dissipation device for LED displays, comprising a body, wherein protective pads are fixedly installed around the body.
[0008] Several heat dissipation devices are symmetrically installed on one side surface of the main body. A dust cover is provided on one side surface of the main body. Several dust holes are opened on the side surface of the dust cover away from the main body. A slider is symmetrically installed on the side surface of the dust cover close to the main body. The slider is in close contact with the main body. Connecting blocks are symmetrically installed on both sides of the dust cover. The connecting blocks are fixedly connected to the main body. A fixing frame is fixedly connected to the side surface of the connecting blocks away from the main body.
[0009] Also includes:
[0010] A fixing component is connected through the top side surface of the fixing frame;
[0011] The fixing component includes a sleeve that is connected through the fixing frame;
[0012] The top surface of the sleeve is rotatably connected to a rotating block.
[0013] Preferably, a rotating rod is fixedly connected to the middle of the bottom surface of the rotating block, and a rotating plate is fixedly connected to the bottom surface of the rotating rod.
[0014] Preferably, a pressing block is attached to the bottom surface of the rotating plate, and a clamping rod is fixedly connected to the middle of the bottom surface of the pressing block.
[0015] Preferably, a compression spring is sleeved on the surface of the clamping rod, the top surface of the compression spring is fixedly connected to the extrusion block, and the bottom surface of the compression spring is fixedly connected to the sleeve.
[0016] Preferably, the clamp rod and the sleeve are connected through each other.
[0017] Preferably, a slot is provided on the side of the slider away from the body, and the slot engages with the locking rod.
[0018] Preferably, the protective pad is made of rubber.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This dustproof and heat dissipation device for LED displays, by setting a fixing component, allows for quick disassembly of the dust cover, thereby enabling the cleaning of dust adhering to the dust cover. This prevents dust from reducing the heat dissipation efficiency of the heat dissipation device to the main body. At the same time, by installing protective pads at the four corners of the display screen, it can provide a certain degree of protection for the main body. The specific details are as follows:
[0020] 1. By setting a fixed component, when the dust cover needs to be disassembled, rotating the rotating block causes the rotating rod to rotate, which in turn causes the rotating plate to rotate, thus pressing the extrusion plate. The top of the extrusion plate is irregularly shaped, divided into a high point and a low point, each with an arc-shaped limiting groove. This ensures that when the rotating plate rotates to its low point, its bottom is positioned within the arc-shaped limiting groove. Under the action of the compression spring, the extrusion plate rises, causing the clamping rod to rise as well. Once the clamping rod has risen a certain distance... Then, the lever separates from the slot, allowing the dust cover to be pushed to the left or right to remove it for cleaning. When installing the dust cover, the slider on the dust cover is inserted into the connecting block from the side. Then, the rotating block is rotated again, causing the rotating block to drive the rotating plate. As the rotating plate moves from a low position to a high position, it presses against the extrusion plate, causing the extrusion plate to descend. The descent of the extrusion plate causes the lever to descend, thus engaging the lever with the slot and completing the installation of the dust cover. This allows the dust cover to protect the heat dissipation area of the main body from dust.
[0021] 2. By incorporating protective pads made of rubber, the pads can protect the four corners of the display body, preventing corner damage, cracks, or even damage to the internal structure of the screen. Simultaneously, the pads act as a buffer, reducing the direct impact of external forces on the corners and effectively protecting the integrity of the display screen and lowering the risk of damage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 This utility model provides a technical solution: a dustproof and heat dissipation device for an LED display screen, comprising a body 1, with protective pads 2 fixedly installed around the body 1; a plurality of heat dissipation devices 3 symmetrically installed on one side surface of the body 1; a dust cover 4 provided on one side surface of the body 1, with a plurality of dustproof holes 5 opened on the side surface of the dust cover 4 away from the body 1; sliders 6 symmetrically installed on the side surface of the dust cover 4 near the body 1, the sliders 6 being in close contact with the body 1; connecting blocks 7 symmetrically installed on both sides of the dust cover 4, the connecting blocks 7 being fixedly connected to the body 1; and a fixing frame 8 fixedly connected to the side surface of the connecting blocks 7 away from the body 1; further comprising: a fixing component 9 penetratingly connected to the side surface of the fixing frame 8 near the top; wherein the fixing component 9 includes a sleeve 901 penetratingly connected to the fixing frame 8; wherein a rotating block 902 is rotatably connected to the top surface of the sleeve 901, such as... Figure 1-5 As shown, by setting the fixing component 9, the protective cover can be quickly disassembled, thereby cleaning the dust attached to the protective cover and preventing the dust from reducing the heat dissipation efficiency of the heat dissipation device 3 on the main body 1. At the same time, by installing protective pads 2 at the four corners of the display screen, the main body 1 can be protected to a certain extent. The heat dissipation device 3 is a fan in the prior art, and its working principle is the same as that of the prior art.
[0030] A rotating rod 903 is fixedly connected to the bottom surface of the rotating block 902. A rotating plate 904 is fixedly connected to the bottom surface of the rotating rod 903. A pressing block 905 is attached to the bottom surface of the rotating plate 904. A locking rod 906 is fixedly connected to the bottom surface of the pressing block 905. A compression spring 907 is sleeved on the surface of the locking rod 906. The top surface of the compression spring 907 is fixedly connected to the pressing block 905, and the bottom surface of the compression spring 907 is fixedly connected to the sleeve 901. The locking rod 906 is connected through the sleeve 901. A slot 10 is formed on the side of the slider 6 away from the body 1. The slot 10 is engaged with the locking rod 906. Figure 4 , 5 As shown, when the dust cover 4 needs to be disassembled, rotating the rotating block 902 causes the rotating rod 903 to rotate. The rotation of the rotating rod 903 causes the rotating plate 904 to rotate, which in turn causes the rotating plate 904 to press against the extrusion plate. The top of the extrusion plate is irregularly shaped, divided into a high point and a low point. Both the high point and the low point are provided with arc-shaped limiting grooves. When the rotating plate 904 rotates to the low point, the bottom of the rotating plate 904 is located inside the arc-shaped limiting groove. Under the action of the compression spring 907, the extrusion plate rises, which causes the locking rod 906 to rise. After the locking rod 906 rises to a certain distance, it separates from the locking groove 10, allowing the dust cover 4 to be pushed to the left or right to be disassembled for cleaning.
[0031] Protective pad 2 is made of rubber, such as Figure 1 As shown, the protective pad 2 is made of rubber, which allows the protective pad 2 to protect the four corners of the main body 1, thereby preventing the main body 1 from being damaged at the corners, cracked, or even damaged in the internal structure of the screen. At the same time, the protective pad 2 can act as a buffer, reducing the direct impact of external forces on the corners, effectively protecting the integrity of the display screen and reducing the risk of damage.
[0032] Working principle: Before using this dustproof and heat dissipation device for LED displays, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5As shown, firstly, by setting the fixing component 9, when the dust cover 4 needs to be disassembled, the rotating block 902 is rotated, causing the rotating rod 903 to rotate. The rotation of the rotating rod 903 causes the rotating plate 904 to rotate, thus causing the rotating plate 904 to squeeze the extrusion plate. The top of the extrusion plate is irregularly shaped, divided into a high point and a low point, each with an arc-shaped limiting groove. This ensures that when the rotating plate 904 rotates to the low point, its bottom is positioned inside the arc-shaped limiting groove. Under the action of the compression spring 907, the extrusion plate rises, causing the clamping rod 906 to rise. When the clamping rod 906 rises to a certain position... After the distance is reached, the locking rod 906 separates from the slot 10, allowing the dust cover 4 to be pushed to the left or right to remove it for cleaning. When installing the dust cover 4, the slider 6 on the dust cover 4 is inserted into the connecting block 7 from the side. Then, the rotating block 902 is rotated again, causing the rotating block 902 to drive the rotating plate 904. As the rotating plate 904 moves from a low position to a high position, it presses the extrusion plate, causing the extrusion plate to descend. The descent of the extrusion plate causes the locking rod 906 to descend, thus engaging the locking rod 906 with the slot 10, completing the installation of the dust cover 4. This allows the dust cover 4 to protect the heat dissipation area of the main body 1 from dust.
[0033] Secondly, by setting up protective pads 2, which are made of rubber, the protective pads 2 can protect the four corners of the main body 1, thereby preventing the main body 1 from being damaged at the corners, cracked, or even damaged in the internal structure of the screen. At the same time, the protective pads 2 can act as a buffer, reducing the direct impact of external forces on the corners, effectively protecting the integrity of the display screen and reducing the risk of damage.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
