Description

Technical Field

[0001] This invention relates to the field of displays, specifically an explosion-proof LED display with a splicing protection structure. Background Technology

[0002] In current LED display applications, especially those requiring movement, transportation, or use in vibrating environments, existing technologies present numerous problems. This is particularly true for spliced ​​LED displays; without protective structures, the screens are highly susceptible to cracking.

[0003] On the one hand, existing LED display screen fixing and protection structures are often quite complex, which not only increases production costs but also makes installation and disassembly cumbersome, consuming a significant amount of time and manpower. This means that users need to invest more effort in the setup and maintenance of the equipment during actual use.

[0004] On the other hand, existing fixing methods for spliced ​​LED displays struggle to achieve precise positioning, making the displays highly susceptible to vibration during movement. Due to the lack of effective fixing and cushioning measures, internal electronic components are prone to loosening and damage under prolonged vibration, affecting the display's normal performance and shortening its lifespan. Furthermore, most existing devices lack reusability; once damaged or no longer suitable, they require complete replacement, resulting in resource waste and increased costs. Therefore, those skilled in the art have proposed an explosion-proof LED display with a splicing protection structure to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an explosion-proof LED display screen with a splicing protection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An explosion-proof LED display screen with a splicing protection structure includes an outer casing and an inner casing slidably connected to the inside of the outer casing. A locking rod is slidably connected to the inside of the outer casing, and the locking rod is parallel to the inner end face of the inner casing. A mounting block is fixedly connected to one end of the locking rod inside the outer casing. Two first magnets are fixedly connected to the mounting block, with opposite magnetic poles on the outward-facing sides of the first magnets. An adjusting rod is rotatably connected to the side wall of the outer casing. A mounting base is fixedly connected to the end of the adjusting rod, and a first handle is fixedly connected to the outer end of the adjusting rod. A second magnet is fixedly connected to the mounting base, with opposite magnetic poles on the outward-facing sides of the second magnet. The first magnet and the second magnet are magnetically attracted or repelled. A locking ring is fixedly connected to the middle of the locking rod, and a locking hook is fixedly connected to the middle of the inner end face of the inner casing. The locking ring and the locking hook cooperate with each other.

[0008] As a further aspect of the present invention: a first spring is fixedly connected between the locking rod and the inner wall of the outer box, and the locking rod moves toward the end closer to the second magnet under the action of the spring force of the first spring.

[0009] As a further aspect of the present invention, a clamping mechanism is fixedly connected to the outer box body.

[0010] As a further embodiment of the present invention: the clamping mechanism includes a threaded column rotatably connected to the outer box body, a second handle fixedly connected to the outer end of the threaded column, two connecting displacement plates threadedly connected to the outer side of the threaded column, the connecting displacement plates being slidably connected to the locking rod, the connecting displacement plates moving towards each other or away from each other, and a first tilting rod rotatably connected to the side of the connecting displacement plates facing the inner box body, the other end of the first tilting rod being rotatably connected to the clamping plate.

[0011] As a further embodiment of the present invention: the clamping mechanism is provided in two sets, and the two clamping mechanisms are driven by the same threaded column, and the clamping mechanism cooperates with the inner end face of the inner box.

[0012] As a further embodiment of the present invention: a through hole is provided on the inner end face of the inner box, a movable end plate is slidably connected to the inner side of the inner box, the sliding direction of the movable end plate is consistent with the pulling direction of the inner box, a locking slide plate is slidably connected to the side of the movable end plate near the clamping mechanism, a second spring is connected between the locking slide plate and the movable end plate, a fastening groove is provided on the side wall of the inner box, a fastening end block is fixedly connected to the end of the locking slide plate, the fastening end block passes through the fastening groove and cooperates with the inner wall of the outer box, a second inclined rod of equal length is rotatably connected to the side of the locking slide plate near the clamping mechanism through a torsion spring, and a driving plate is rotatably connected to the other end of the second inclined rod through a torsion spring, the driving plate cooperates with the clamping mechanism.

[0013] As a further aspect of the present invention: when the clamping mechanism contacts the driving plate, under the action of the torsion spring, the clamping mechanism first drives the locking slide plate and the moving end plate to be parallel as a whole. When the moving end plate cannot move, the locking slide plate overcomes the torsion force of the torsion spring and moves towards the inner wall of the outer box. At this time, the fastening end block is clamped against the inner wall of the outer box.

[0014] As a further embodiment of the present invention: a screw sleeve is fixedly connected to the end face of the inner box near the outer side, and an inner screw rod is connected to the screw sleeve by an internal thread. An adjustment end plate is rotatably connected to one end of the inner screw rod located inside the inner box.

[0015] As a further embodiment of the present invention: shock-absorbing airbags are fixedly connected to both sides of the inner box, and a third handle is fixedly connected to the outer side wall of the inner box.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a simple structure and is easy to use. By placing the spliced ​​LED display screen in the inner box, it can be fixed by the connecting structure on the outer box and the inner box, which can achieve a good positioning effect and avoid the display screen from vibrating during movement and thus causing damage. The device is simple and easy to operate for positioning the display screen, can be reused, and is worth promoting. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1: Please refer to Figure 1 and Figure 5An explosion-proof LED display screen with a splicing protection structure includes an outer box 1 and an inner box 2 slidably connected to the inside of the outer box 1. A locking rod 3 is slidably connected to the inside of the outer box 1, and the locking rod 3 is parallel to the inner end face of the inner box 2. A mounting block 4 is fixedly connected to one end of the locking rod 3 located inside the outer box 1. Two first magnets 5 are fixedly connected to the mounting block 4, and the magnetic poles of the first magnets 5 facing outwards are opposite. An adjusting rod 6 is rotatably connected to the side wall of the outer box 1. A mounting base plate 7 is fixedly connected to the end of the adjusting rod 6. A first handle 8 is fixedly connected to the outer end of the adjusting rod 6. A second magnet 9 is fixedly connected to the mounting base plate 7, and the magnetic poles of the second magnet 9 facing outwards are opposite. The first magnet 5 and the second magnet 9 are magnetically attracted or repelled. A locking ring 10 is fixedly connected to the middle of the locking rod 3. A locking hook 11 is fixedly connected to the middle of the inner end face of the inner box 2, and the locking ring 10 and the locking hook 11 cooperate. A first spring 12 is fixedly connected between the locking rod 3 and the inner wall of the outer box 1. Under the spring force of the first spring 12, the locking rod 3 moves toward the end closer to the second magnet 9. Alternatively, the locking ring 10 can also be installed on the inner box 2. In this case, the locking hook 11 needs to be installed on the locking rod 3 to lock it in place.

[0028] First, test the device to ensure it functions correctly. Then, place the LED display screen inside the inner housing 2 and secure it. Next, slide the inner housing 2 inside the outer housing 1. Rotate the first handle 8 to rotate the second magnet 9 on the mounting base 7. During rotation, the two magnets on the second magnet 9 will magnetically connect with the two magnets on the first magnet 5. The locking rod 3 will slide into the outer housing 1, simultaneously engaging the locking ring 10 and the locking hook 11 to lock the inner housing 2 securely. During transportation, the outer housing 1 protects the display screen from damage. To remove the display screen, reverse the first handle 8. When the first magnet 5 and the second magnet 9 repel each other, the locking rod 3 will slide outward to unlock, allowing the display screen to be removed. The first spring 12 further enhances the locking force during locking. Conversely, if the locking rod 3 does not slide smoothly outward, external force can be used to push the locking rod 3 outward.

[0029] Please see Figure 4 and Figure 5A clamping mechanism 13 is fixedly connected to the outer box 1. The clamping mechanism 13 includes a threaded post 14 rotatably connected to the outer box 1. A second handle 15 is fixedly connected to the outer end of the threaded post 14. Two connecting displacement plates 16 are threadedly connected to the outer side of the threaded post 14. The connecting displacement plates 16 are slidably connected to the locking rod 3. The connecting displacement plates 16 can move towards each other or away from each other. A first tilting rod 17 is rotatably connected to the side of the connecting displacement plates 16 facing the inner box 2. The other end of the first tilting rod 17 is rotatably connected to a clamping plate 18. Two sets of clamping mechanisms 13 are provided. The two clamping mechanisms 13 are driven by the same threaded post 14. The clamping mechanism 13 cooperates with the inner end face of the inner box 2.

[0030] The setting of the clamping mechanism 13 can further improve the reliability of the device fixation. When the second handle 15 is rotated, the second handle 15 drives the threaded column 14 to rotate. The threaded column 14 drives the connecting displacement plate 16 to move towards each other, thereby causing the first tilting rod 17 to drive the clamping plate 18 to move towards one side of the inner box 2 and clamp the inner box 2 to prevent relative sliding between the inner box 2 and the outer box 1. In order to ensure the engagement of the locking ring 10 and the locking hook 11, there is usually a large engagement margin between the two. Therefore, relative sliding is easy to occur after engagement. However, after the clamping plate 18 clamps the inner box 2, relative sliding will not occur.

[0031] Example 2: This example is an improvement upon the previous example, with the following modifications: Please refer to... Figure 2 , Figure 3 and Figure 5 The inner box 2 has a through hole 19 on its inner end face. A movable end plate 20 is slidably connected to the inner side of the inner box 2. The sliding direction of the movable end plate 20 is the same as the pulling direction of the inner box 2. A locking slide plate 21 is slidably connected to the side of the movable end plate 20 near the clamping mechanism 13. A second spring 22 is connected between the locking slide plate 21 and the movable end plate 20. A fastening groove 23 is provided on the side wall of the inner box 2. A fastening end block 24 is fixedly connected to the end of the locking slide plate 21. The fastening end block 24 passes through the fastening groove 23 and cooperates with the inner wall of the outer box 1. A parallel and equal-length second inclined rod 25 is rotatably connected to the side of the locking slide plate 21 near the clamping mechanism 13 through a torsion spring. The other end of the second inclined rod 25 is rotatably connected to a driving plate 26 through a torsion spring. The driving plate 26 cooperates with the clamping mechanism 13.

[0032] When the clamping mechanism 13 contacts the driving plate 26, under the action of the torsion spring, the clamping mechanism 13 first drives the locking slide plate 21 and the moving end plate 20 to be parallel as a whole. When the moving end plate 20 cannot move, the locking slide plate 21 overcomes the torsion spring torque and moves towards the inner wall of the outer box 1. At this time, the fastening end block 24 abuts against the inner wall of the outer box 1.

[0033] A through hole 19 is made in the inner box 2, and the clamping plate 18 will directly enter the inner box 2 without applying pressure to the inner box 2. Then it will abut against the drive plate 26. The moving end plate 20 and the locking slide plate 21 will slide inward synchronously to clamp and position the front and rear ends of the screen inside. As the clamping plate 18 moves further, the locking slide plate 21 will slide outward and drive the fastening end block 24 to abut against the inner wall of the outer box 1. Then the clamping plate 18 will overcome the friction between the fastening end block 24 and the outer box 1 to drive the inner box 2 to move, so that the locking hook 11 and the locking ring 10 are locked together.

[0034] A screw sleeve 27 is fixedly connected to the outer end face of the inner box 2. An internal screw rod 28 is threaded onto the screw sleeve 27. An adjusting end plate 29 is rotatably connected to one end of the internal screw rod 28 located inside the inner box 2. Before placing the screen, the internal screw rod 28 can be rotated according to the screen size, causing the adjusting end plate 29 to slide inward. This makes the length of the display screen slightly smaller than the distance between the adjusting end plate 29 and the moving end plate 20, which facilitates screen placement and also makes it easier to adjust and fix the moving end plate 20 later.

[0035] Shock-absorbing airbags 30 are fixedly connected to both sides of the inner box 2. The shock-absorbing airbags 30 can prevent damage to the sides of the display screen. A third handle 31 is fixedly connected to the outer wall of the inner box 2. The third handle 31 can easily pull out the inner box 2.

[0036] Working Principle: First, test the device to ensure it functions correctly. Then, place the LED display screen inside the inner housing 2 and secure it. Next, slide the inner housing 2 inside the outer housing 1. Rotate the first handle 8, causing the second magnet 9 on the mounting base 7 to rotate. During rotation, the two magnets of the second magnet 9 will magnetically connect with the two magnets of the first magnet 5. The locking rod 3 slides into the outer housing 1, simultaneously engaging the locking ring 10 and the locking hook 11 to lock the inner housing 2 securely. During transportation, the outer housing 1 protects the display screen from damage. To remove the display screen, reverse the first handle 8. When the first magnet 5 and the second magnet 9 repel each other, the locking rod 3 slides outward to unlock, allowing the display screen to be removed. The first spring 12 further enhances the locking force during locking; conversely, if the locking rod 3 does not slide smoothly outward, external force can be used to push the locking rod 3 outward.

[0037] The setting of the clamping mechanism 13 can further improve the reliability of the device fixation. When the second handle 15 is rotated, the second handle 15 drives the threaded column 14 to rotate. The threaded column 14 drives the connecting displacement plate 16 to move towards each other, thereby causing the first tilting rod 17 to drive the clamping plate 18 to move towards one side of the inner box 2 and clamp the inner box 2 to prevent relative sliding between the inner box 2 and the outer box 1. In order to ensure the engagement of the locking ring 10 and the locking hook 11, there is usually a large engagement margin between the two. Therefore, relative sliding is easy to occur after engagement. However, after the clamping plate 18 clamps the inner box 2, relative sliding will not occur.

[0038] A through hole 19 is made in the inner box 2, and the clamping plate 18 will directly enter the inner box 2 without applying pressure to the inner box 2. Then it will abut against the drive plate 26. The moving end plate 20 and the locking slide plate 21 will slide inward synchronously to clamp and position the front and rear ends of the screen inside. As the clamping plate 18 moves further, the locking slide plate 21 will slide outward and drive the fastening end block 24 to abut against the inner wall of the outer box 1. Then the clamping plate 18 will overcome the friction between the fastening end block 24 and the outer box 1 to drive the inner box 2 to move, so that the locking hook 11 and the locking ring 10 are locked together.
