Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED digital tube equipment technology, and in particular to an LED digital tube display device. Background Technology
[0002] An LED digital tube is a display device composed of multiple light-emitting diodes (LEDs) used to display numbers, letters, or simple symbols. It is usually composed of 7 strip LEDs, each of which can be lit or turned off independently. Different combinations can be used to display numbers 0-9 or parts of letters. In addition, some LED digital tubes also have a decimal point segment for displaying decimals.
[0003] In existing LED digital tube display technology, the display body and mounting components are usually rigidly connected, which cannot effectively absorb the impact force generated by external collisions or vibrations. When subjected to external force, the impact force is directly transmitted to the display body and its internal electronic components, causing component damage or abnormal display function. Under vibration or impact environment, the display body is prone to displacement, affecting the stability of the device and the display effect. Long-term vibration can also easily cause the connecting parts to loosen, further increasing the risk of device damage. Due to the lack of buffer protection, the display body and its internal components are more easily damaged when subjected to impact, increasing the maintenance frequency and cost of the device. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an LED digital tube display device, which aims to improve the problem that existing LED digital tube display devices cannot perform buffering.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED digital tube display device, comprising a base and a mounting plate, wherein fixed rods are fixedly connected to both sides of the bottom of the mounting plate, and positioning rods are fixedly connected to both sides of the interior of the base, and two fixed rods are slidably connected to the outside of the positioning rods, and one end of a movable support rod is rotatably connected to both sides of the exterior of the two fixed rods, and the other end of a plurality of movable support rods is rotatably connected to a movable block, upright plates are fixedly connected to all four sides of the interior of the base, and guide rods are fixedly connected to opposite sides of the plurality of upright plates, and movable blocks are slidably connected to the outside of the plurality of guide rods, and buffer springs are sleeved on the outside of the plurality of guide rods, and buffer springs are provided inside the two fixed rods, one end of the two buffer springs being fixedly connected to the inside of the fixed rods, and the other end of the two buffer springs being fixedly connected to the upper part of the positioning rods.
[0006] Furthermore, mounting bases are fixedly connected to the upper perimeter of the mounting plate, and protective shells are slidably connected inside the mounting bases. Pull rods are slidably connected to both sides inside the mounting bases, and fixing components are fixedly connected to opposite ends of the pull rods. The fixing components are used to fix the protective shells.
[0007] Furthermore, the fixing component includes a sliding plate and a plug, with multiple sliding plates fixedly connected to opposite ends of multiple pull rods, and plugs fixedly connected to the opposite sides of the multiple sliding plates.
[0008] Furthermore, one end of each of the multiple buffer springs is fixedly connected to one side of the movable block, and the other end of each of the multiple buffer springs is fixedly connected to one side of the upright plate.
[0009] Furthermore, dampers are fixedly connected to the inside of the base on all four sides, and mounting plates are fixedly connected to the upper parts of the multiple dampers.
[0010] Furthermore, each of the multiple sliding plates is fixedly connected to a compression spring on its opposite side, and the multiple sliding plates are slidably connected inside the protective shell.
[0011] Furthermore, the protective shell has insertion holes on all four sides inside, and multiple insertion blocks are slidably connected inside the insertion holes.
[0012] Furthermore, the upper part of the mounting plate is fixedly connected to the display body, and the protective shell is disposed on the outside of the display body.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, when the display body is impacted, the mounting plate moves downward, squeezing the damper and the fixing rod. The fixing rod slides along the positioning rod and compresses the buffer spring one, absorbing part of the impact force. The downward movement of the fixing rod drives the movable support rod to rotate, causing the movable block to slide and compress the buffer spring two, absorbing the remaining impact force. This effectively buffers the display body, reduces displacement caused by vibration or impact, and extends the equipment life.
[0015] 2. In this utility model, by pulling the lever, the sliding plate is moved and the spring is compressed, so that the sliding plate moves the plug out of the plug hole, releasing the fixing of the protective shell, realizing convenient disassembly of the protective cover, making it easy for maintenance personnel to quickly access the internal electronic components, clean or replace damaged parts, and reduce maintenance difficulty and time cost.

[0024] 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.
[0025] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of an LED digital tube display device, comprising a base 1 and a mounting plate 2. Fixing rods 11 are fixedly connected to both sides of the bottom of the mounting plate 2. Positioning rods 13 are fixedly connected to both sides of the interior of the base 1. Two fixing rods 11 are slidably connected to the outside of the positioning rods 13. One end of a movable support rod 14 is rotatably connected to both sides of the outside of the two fixing rods 11. Movable blocks 15 are rotatably connected to the other ends of multiple movable support rods 14. Vertical plates 16 are fixedly connected to all four sides of the interior of the base 1. Guide rods 17 are fixedly connected to opposite sides of the multiple vertical plates 16. The outside of the multiple guide rods 17... Each of the base 1 has a movable block 15 slidably connected to it. Multiple guide rods 17 are fitted with buffer springs 18 on their outer sides. Two fixed rods 11 are fitted with buffer springs 12 inside each of them. One end of each buffer spring 12 is fixedly connected to the inside of the fixed rod 11, and the other end of each buffer spring 12 is fixedly connected to the upper part of the positioning rod 13. One end of each buffer spring 18 is fixedly connected to one side of the movable block 15, and the other end of each buffer spring 18 is fixedly connected to one side of the upright plate 16. Damperes 19 are fixedly connected to the inside of the base 1 around its perimeter, and mounting plates 2 are fixedly connected to the upper part of each damper 19.
[0026] When encountering an external impact, the display body 3 will cause the mounting plate 2 to move downwards. At this time, the downward movement of the mounting plate 2 will apply pressure to the damper 19 and the fixing rod 11. When the mounting plate 2 moves downwards, it will contact the damper 19, which will slow down the movement speed and provide initial impact absorption. After being squeezed, the fixing rod 11 will move downwards and slide outside the positioning rod 13. During this process, the buffer spring 12 is compressed, effectively absorbing part of the impact force. As the fixing rod 11 continues to move downwards, it will drive multiple movable support rods 14 to rotate. The rotation of the movable support rods 14 will further drive the movable block 15 to slide along the outside of the guide rod 17. The guide rod 17 provides a sliding track for the movable block 15 to ensure that it can move in an orderly manner. During this process, the movable block 15 applies pressure to the buffer spring 18, causing it to be compressed, thereby absorbing the remaining impact energy.
[0027] Reference Figure 3 , Figure 4 and Figure 6Mounting plate 2 has mounting bases 5 fixedly connected to its upper perimeter. Protective shells 4 are slidably connected inside each mounting base 5. Pull rods 6 are slidably connected to both sides of the interior of each mounting base 5. Fixing components are fixedly connected to opposite ends of each pull rod 6. The fixing components are used to fix the protective shells 4. The fixing components include sliding plates 7 and inserts 8. Each sliding plate 7 is fixedly connected to opposite ends of each pull rod 6. Inserts 8 are fixedly connected to the opposite sides of each sliding plate 7. Compression springs 9 are fixedly connected to opposite sides of each sliding plate 7. Each sliding plate 7 is slidably connected inside the protective shell 4. Insertion holes 10 are opened around the interior perimeter of the protective shell 4. Inserts 8 are slidably connected inside the insertion holes 10. The display body 3 is fixedly connected to the upper part of mounting plate 2. The protective shell 4 is set outside the display body 3.
[0028] When inspecting the monitor body 3, the staff pulls multiple levers 6. As the levers 6 are pulled, the sliding plates 7 move accordingly, causing the multiple sliding plates 7 to move closer together and apply pressure to the compression spring 9. When the sliding plates 7 move closer together, they apply pressure to the compression spring 9, causing it to undergo elastic deformation. This deformation stores energy. When the spring returns to its shape, this energy is released and used to push the insertion block 8 to move. Under the elastic action of the compression spring 9, the sliding plates 7 will further drive the insertion block 8, causing it to move smoothly out of the socket 10. The socket 10 ensures that the insertion block 8 can be smoothly inserted and removed, thereby facilitating the fixing and disassembly of the protective shell 4. The protective shell 4 is the external covering structure of the monitor body 3, used to protect the internal electronic components from external influences. During inspection, the protective shell 4 needs to be removed to access the internal components.
[0029] Working principle: When the monitor body 3 is impacted, the mounting plate 2 moves downward, pressing against the damper 19 and the fixing rod 11. The fixing rod 11 moves downward under this pressure, sliding outside the positioning rod 13 and pressing against the buffer spring 12. The buffer spring 12 absorbs part of the force. As the fixing rod 11 moves downward, it drives multiple movable support rods 14 to rotate. The rotation of the movable support rods 14 causes the movable block 15 to slide outside the guide rod 17. The sliding of the movable block 15 presses against the buffer spring 18, which absorbs the remaining force. This effectively buffers the monitor body 3, absorbing external impacts and reducing the impact caused by external forces. To prevent device displacement caused by vibration or impact and extend the service life of the equipment, when the main body of the display 3 needs to be repaired, the staff pulls multiple levers 6. When the levers 6 move, they drive the sliding plate 7 to move, bringing the multiple sliding plates 7 closer together and squeezing the compression spring 9. The compression spring 9 undergoes elastic deformation under the pressure of the compression spring 9. Under the action of the compression spring 9, the sliding plate 7 drives the plug 8 to move out of the plug hole 10, releasing the fixation of the protective shell 4. Next, the protective shell 4 can be removed by pulling it up. This makes it easy to disassemble the protective shell 4, allowing maintenance personnel to quickly access the internal electronic components for cleaning, replacement of damaged LEDs or other electronic parts, and reducing maintenance difficulty and time costs.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
