Technical Field
[0001] This utility model belongs to the field of LED display technology, and specifically relates to a protective device for LED displays. Background Technology
[0002] LED electronic displays are a type of display that controls semiconductor light-emitting diodes. They consist of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels arranged evenly. By using different materials, LED pixels of different colors can be manufactured to display various information such as text, graphics, images, animations, market information, videos, and recorded signals.
[0003] However, LED displays face various environmental challenges in actual use, such as vibration, impact, dust, moisture, and high temperature. These factors may damage the display or reduce its performance, thereby affecting its service life and display effect. Existing LED display protective devices mostly use simple protective covers or waterproof shells. Although they can prevent external physical impact and water and dust intrusion to a certain extent, their comprehensive protective effects in terms of shock absorption, heat dissipation, and dust prevention are still insufficient.
[0004] Therefore, a protective device for LED displays is needed to address the problems existing in the prior art. Utility Model Content
[0005] The purpose of this invention is to provide a protective device for LED displays to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for an LED display screen, comprising a fixing frame, the fixing frame being U-shaped, and having buffer grooves or connecting grooves at the middle of the two side plates and at the lower ends of opposite sides. The upper and lower ends of the buffer grooves are respectively fixedly connected to the upper and lower ends of the fixing shaft of a second shock-absorbing component. Fixing plates are fixedly connected to the front and rear sides of the upper surface of the lower end of the fixing frame. The opposite sides of the fixing plates are slidably connected to the front and rear surfaces of the support plate of the support structure. Both ends of the support plate are respectively provided with connecting grooves that penetrate into the buffer grooves. Both ends of the support plate are provided with sliding holes, which are slidably connected to the outer surface of the lower end of the corresponding fixing shaft. An LED display screen is installed in the middle of the upper end of the support plate. The lower end of the support plate is fixedly connected to the upper surface of the lower end of the fixing frame through several first shock-absorbing components. Top plates are installed on the upper ends of the two side plates of the fixing frame.
[0007] It should be noted in the solution that the opposite sides of the two side plates of the fixing frame and the upper end of the support plate are respectively provided with symmetrical first limiting plates or symmetrical second limiting plates on both sides of the LED display screen. One side of the first limiting plate or the second limiting plate is arc-shaped, and the opposite sides of the first limiting plate or the second limiting plate are respectively provided with first buffer pads or second buffer pads.
[0008] It is worth noting that the fixing frame is provided with limiting shafts at the front ends of both sides of the connecting groove, and the support plate is provided with slots at both ends of the front and rear sides. The inner surface of the slots can be slidably connected to the outer surface of the limiting shafts.
[0009] Furthermore, it should be noted that the outer surface of the upper end of the fixed shaft is provided with threads, and the outer surface of the fixed shaft is slidably connected from bottom to top to a support plate, a first sliding plate, a spring steel, a second sliding plate, or an adjusting bolt connected by threads. The outer surface of the peak of the spring steel is provided with an anti-slip coating, and anti-slip pads are provided on both the front and rear sides of the buffer groove.
[0010] In a preferred embodiment, the front end of the fixing frame is provided with a front plate, and the rear end of the fixing frame is provided with a rear plate, and the lower end of the rear plate is provided with a plurality of heat dissipation grooves.
[0011] In a preferred embodiment, a guide plate is provided at the upper end of the top plate.
[0012] In a preferred embodiment, the upper outer sides of both side plates of the fixing frame are provided with operating grooves, and a connecting door is hinged to one side of each operating groove.
[0013] In a preferred embodiment, the first shock-absorbing component includes a first connecting shaft and a second connecting shaft. The first connecting shaft has a sliding groove inside, and the lower end of the second connecting shaft is fixedly connected to a sliding block. The sliding blocks can be slidably connected to the inner surface of the sliding groove, and shock-absorbing springs are provided on the outer surfaces of the first and second connecting shafts.
[0014] Compared with the prior art, the protective device for LED displays provided by this utility model has at least the following beneficial effects:
[0015] (1) When the LED display screen vibrates, it will be transmitted to several damping springs of the first damping component in the first time. When the damping springs start to vibrate, they will drive the support plate to vibrate. The support plate will squeeze the first sliding plate, that is, the first sliding plate will squeeze the S-shaped spring steel at its upper end. The bent section of the S-shaped spring steel will undergo elastic deformation. At the same time, at the peak point (i.e. the highest point of the bend) and the two sides of the buffer groove, there are anti-slip pads that are fixedly connected to produce relative sliding or friction. The existence of friction will hinder the free vibration of the S-shaped spring steel, thereby reducing the vibration amplitude of several damping springs and thus damping the device.
[0016] (2) The front plate of acrylic transparent material at the front end of the fixing frame and the rear plate with several heat dissipation grooves at the rear end of the fixing frame can increase the dustproof, waterproof and heat dissipation functions of the LED display screen.

Detailed Implementation
[0022] The present invention will be further described below with reference to the embodiments.
[0023] Please see Figure 1-4This utility model provides a protective device for an LED display screen, comprising: a fixed frame 1, the fixed frame 1 being U-shaped, and the middle of the two side plates and the lower end of the opposite side of the fixed frame 1 being provided with buffer grooves 101 or connecting grooves 102, the upper and lower ends of the buffer grooves 101 being fixedly connected to the upper and lower ends of the fixed shaft 401 of the second shock-absorbing component 4, and the front and rear sides of the upper surface of the lower end of the fixed frame 1 being fixedly connected with fixed plates 2, the opposite sides of the fixed plates 2 being slidably connected to the front and rear surfaces of the support plate 301 of the support structure 3, the two ends of the support plate 301 being respectively provided with connecting grooves 102 penetrating into the buffer grooves 101, and the two ends of the support plate 301 being provided with sliding holes 302, the sliding holes 302 being slidably connected to the outer surface of the lower end of the corresponding fixed shaft 401, and the LED display screen 5 being installed in the middle of the upper end of the support plate 301, and the lower end of the support plate 301 being fixedly connected to the upper surface of the lower end of the fixed frame 1 through a plurality of first shock-absorbing components 306, and the upper ends of the two side plates of the fixed frame 1 being provided with top plates 8.
[0024] Further as Figure 3 As shown, it is worth noting that the two side plates of the fixing frame 1 and the upper end of the support plate 301 are respectively provided with symmetrical first limiting plates 105 or symmetrical second limiting plates 304 on both sides of the LED display screen 5. One side of the first limiting plate 105 or the second limiting plate 304 is arc-shaped, and the opposite side of the first limiting plate 105 or the second limiting plate 304 is respectively provided with a first buffer pad 106 or a second buffer pad 305. Through the first limiting plate 105, the second limiting plate 304, the first buffer pad 106 or the second buffer pad 305, the LED display screen 5 can be restricted and the connection points can be buffered and protected.
[0025] Further as Figure 3 As shown, it is worth noting that the fixing frame 1 is provided with limiting shafts 107 at the front ends of both sides of the connecting groove 102, and the support plate 301 is provided with slots 303 at both ends of the front and rear sides. The inner surface of the slots 303 can be slidably connected to the outer surface of the limiting shafts 107. By slidably connecting the inner surface of the slots 303 to the outer surface of the limiting shafts 107, the position and movement trajectory of the support plate 301 can be further restricted.
[0026] Further as Figure 1As shown, it is worth noting that the upper outer surface of the fixed shaft 401 is threaded, and the outer surface of the fixed shaft 401 is slidably connected from bottom to top to the support plate 301 of the support structure 3, the first sliding plate 402, the spring steel 403, and the second sliding plate 404, or threaded to the adjusting bolt 405. The outer surface of the peak of the spring steel 403 is provided with an anti-slip coating 406, and anti-slip pads 407 are provided on both the front and rear sides of the buffer groove 101. When the LED display screen 5 vibrates, it will be transmitted to several damping springs 3065 of the first damping component 306 immediately. When 3065 starts to vibrate, it causes the support plate 301 to vibrate. The support plate 301 will press the first sliding plate 402, that is, the first sliding plate 402 will press the S-shaped spring steel 403 at its upper end. The bent section of the S-shaped spring steel 403 will undergo elastic deformation. At the same time, at the peak point (i.e. the highest point of the bend), there are anti-slip pads 407 fixedly connected to both sides of the buffer groove 101, which will produce relative sliding or friction. The existence of friction will hinder the free vibration of the S-shaped spring steel 403, thereby reducing the vibration amplitude of some damping springs 3065, thus damping the LED display screen 5.
[0027] The solution has the following working process: When the LED display screen 5 vibrates, it will be transmitted to several damping springs 3065 of the first damping component 306 immediately. When the damping springs 3065 start to vibrate, they will drive the support plate 301 to vibrate. The support plate 301 will squeeze the first sliding plate 402, that is, the first sliding plate 402 will squeeze the S-shaped spring steel 403 at its upper end. The bent section of the S-shaped spring steel 403 will undergo elastic deformation. At the same time, at the peak point (i.e. the highest point of the bend), there are anti-slip pads 407 fixedly connected to both sides of the buffer groove 101 to generate relative sliding or friction. The existence of friction will hinder the free vibration of the S-shaped spring steel 403, thereby reducing the vibration amplitude of several damping springs 3065.
[0028] As can be seen from the above working process, the LED display screen 5 can be restricted and the connection point can be buffered and protected by the first limiting plate 105, the second limiting plate 304, the first buffer pad 106 or the second buffer pad 305. The inner surface of the slot 303 can be fitted and slidably connected to the outer surface of the limiting shaft 107, which can further restrict the position and movement trajectory of the support plate 301.
[0029] Further as Figure 1 As shown, it is worth noting that the front end of the mounting bracket 1 is provided with a front plate 7, and the rear end of the mounting bracket 1 is provided with a rear plate 6. The lower end of the rear plate 6 is provided with several heat dissipation grooves 601. Through the front plate 7 of acrylic transparent material provided at the front end of the mounting bracket 1 and the rear plate 6 of the mounting bracket 1 with several heat dissipation grooves 601 provided at the rear end of the mounting bracket 1, the dustproof, waterproof and heat dissipation of the LED display screen 5 can be increased.
[0030] Further as Figure 1 As shown, it is worth noting that a guide plate 801 is provided at the upper end of the top plate 8, which increases the waterproofness of the device.
[0031] Further as Figure 2 As shown, it is worth noting that both sides of the fixed frame 1 are provided with an operation groove 103 on the upper outer side. A connecting door 104 is hinged to one side of the operation groove 103. Through the operation groove 103, the bending degree of the spring steel 403 can be adjusted by adjusting the adjusting bolt 405.
[0032] Further as Figure 4 As shown, it is worth noting that the first shock-absorbing component 306 includes a first connecting shaft 3061 and a second connecting shaft 3063. The first connecting shaft 3061 has a sliding groove 3062 inside. The lower end of the second connecting shaft 3063 is fixedly connected to a sliding block 3064. The sliding blocks 3064 can be slidably connected to the inner surface of the sliding groove 3062. The outer surfaces of the first connecting shaft 3061 and the second connecting shaft 3063 are provided with shock-absorbing springs 3065. Through the first shock-absorbing component 306, the vibration generated by the LED display screen 5 can be converted into the vibration of several shock-absorbing springs 3065.
[0033] In summary: When the LED display screen 5 vibrates, the vibration is immediately transmitted to the damping springs 3065 of the first damping component 306. When the damping springs 3065 begin to vibrate, they cause the support plate 301 to vibrate. The support plate 301 then presses against the first sliding plate 402, specifically the S-shaped spring steel 403 at its upper end. The bent section of the S-shaped spring steel 403 undergoes elastic deformation. Simultaneously, at the peak (i.e., the highest point of the bend), anti-slip pads 407 are fixedly connected to both sides of the buffer groove 101, resulting in relative sliding or friction. The presence of friction hinders the movement of the S-shaped spring. The free vibration of steel 403 reduces the vibration amplitude of several damping springs 3065. The front plate 7 of acrylic transparent material at the front end of the fixing frame 1 and the rear plate 6 with several heat dissipation grooves 601 at the rear end of the fixing frame 1 can increase the dustproof, waterproof and heat dissipation of the LED display screen 5. The guide plate 801 increases the waterproofness of the device. The operating groove 103 makes it easy to adjust the bending degree of spring steel 403 by adjusting bolt 405. The first damping component 306 can convert the vibration generated by the LED display screen 5 into the vibration of several damping springs 3065.
