Description

Technical Field

[0001] This application relates to the field of dot matrix screen technology, and in particular to a dot matrix screen with a flexible connecting hinge. Background Technology

[0002] A dot matrix display is a type of display device composed of a series of tiny dots that can emit light or change color to display images and text. Each dot is independently controlled, and by lighting up or turning off these dots in different positions, various patterns and characters can be formed.

[0003] Regarding the aforementioned technologies, conventional dot matrix screens cannot be folded, and if a customized dot matrix screen is too long, it is inconvenient to transport it. Summary of the Invention

[0004] To enable folding of the dot matrix screen and facilitate its transportation, this application provides a dot matrix screen with a flexible connecting hinge.

[0005] The dot matrix screen with a flexible connecting hinge provided in this application adopts the following technical solution:

[0006] A dot matrix screen with a flexible connecting hinge includes a folding rod and several screens. Several support blocks are slidably disposed on the folding rod, and each support block corresponds to one of the screens. The screens are disposed on the support blocks. A flipping component is disposed on the folding rod to allow the several support blocks to rotate simultaneously.

[0007] By adopting the above technical solution, the flipping component enables all the support blocks to flip and move to one end of the folding rod at the same time. All the screens are flipped and stacked together at one end of the folding rod. Finally, the folding rod is retracted, thereby reducing the space occupied by the dot matrix screen and facilitating the transportation of long dot matrix screens.

[0008] Optionally, the flipping assembly includes several first links. A first gear is provided on the first support block located at the top of the folding rod. The first gear is rotatably mounted on the folding rod. The remaining support blocks are connected to second links. The several second links are parallel to each other. Each second link is provided with a second gear. The first link is located between two second links. One end of the first link is hinged to one of the second links. The other end of the first link is provided with a third gear. The third gear meshes with the second gear of another second link. The second gear and the third gear are slidably mounted on the folding rod. The meshing second gear and the third gear are rotatably connected to a sliding block. The third gear of the uppermost first link is rotatably mounted on the folding rod and meshes with the first gear. The uppermost first link is hinged to the adjacent second link.

[0009] By adopting the above technical solution, a tool is used to rotate the first connecting rod located at the top of the folding rod. The first connecting rod at the top of the folding rod drives the third gear to rotate, and the third gear drives the first gear to rotate, thereby causing the first support block located at the top of the folding rod to rotate. At the same time, the first connecting rod at the top of the folding rod lifts the second connecting rod below it. The second connecting rod moves towards the top of the folding rod and rotates. The second connecting rod drives the second gear and the support block connected to it to rotate. The second connecting rod also drives the support block to gradually move closer to the top of the folding rod. Meanwhile, the second gear drives the first gear to rotate, and the first gear drives the corresponding first connecting rod to rotate. The first connecting rod continues to drive the corresponding second connecting rod to rotate. Finally, rotating the first connecting rod at the top of the folding rod allows all the screens to flip and fold and move closer to the top of the folding rod. Finally, the folding rod is retracted, thereby reducing the space occupied by the dot matrix screen.

[0010] Optionally, the flipping assembly includes a plurality of first rotating rods and a plurality of second rotating rods. The first rotating rods correspond one-to-one with the support blocks. The first support block located at the top of the folding rod is rotatably mounted on the folding rod. The remaining support blocks are all connected to the corresponding first rotating rods. A plurality of first rotating shafts are slidably mounted on the folding rod. The first rotating shafts correspond one-to-one with the first rotating rods, and the first rotating rods are rotatably connected to the corresponding first rotating shafts. The support block located at the top of the folding rod is hinged to a second rotating rod. The support block located at the top of the folding rod and the corresponding second rotating rod are connected together by a connector. The connector is slidably mounted on the folding rod. The remaining second rotating rods are hinged to the corresponding first rotating rods. The first rotating rods and the second rotating rods are staggered to form a parallelogram structure.

[0011] By adopting the above technical solution, the second rotating rod located at the top of the folding rod is rotated. The second rotating rod drives the first rotating rod connected to it to rotate around the corresponding first rotating axis. At the same time, the first rotating rod moves towards the top of the folding rod along with the first rotating axis. When the first rotating rod rotates, it drives the support block to rotate and move towards the top of the folding rod. When the first rotating rod rotates, it drives other connected second rotating rods to rotate. The other second rotating rods drive other first rotating rods to rotate, forming a whole linkage. When the second rotating rod located at the top of the folding rod rotates, it drives the connector to make the support block at the top of the folding rod rotate. This realizes that all the screens flip and fold and move towards the top of the folding rod. Finally, the folding rod is retracted, thereby reducing the space occupied by the dot matrix screen.

[0012] Optionally, the connector includes a second pivot, a first support rod, and a second support rod. The second pivot is slidably disposed on the folding rod. One end of the first support rod is hinged to the second pivot, and the other end of the first support rod is hinged to the support block. One end of the second support rod is hinged to the second pivot, and the other end of the second support rod is hinged to the second pivot located at the top of the folding rod.

[0013] By adopting the above technical solution, when the second rotating rod at the top of the folding rod rotates, it pulls the second support rod to rotate and move towards the top of the folding rod. The second support rod drives the second rotating shaft and the first support rod to move towards the folding rod. At the same time, the first support rod rotates and drives the support block to rotate.

[0014] Optionally, the folding rod includes several connecting rods, each with a sliding groove. The sliding grooves of the several connecting rods are connected, and adjacent folding rods are connected by hinges. The adjacent hinges are staggered on both sides of the connecting rod.

[0015] By adopting the above technical solution, the connecting rods are folded together to eventually form a retractable folded rod.

[0016] Optionally, the support block has an insertion slot, the screen has an insertion block, the insertion block is inserted into the insertion slot, and the support block is threadedly connected to a clamping bolt, which clamps against the insertion block.

[0017] By adopting the above technical solution, the plug block is inserted into the plug slot, and then the tightening bolt is rotated to tighten the plug block, thereby fixing the screen on the support block.

[0018] Optionally, the plug block is connected to an abutment plate, both the abutment plate and the plug block are disposed in the plug slot, and the tightening bolt is located above the abutment plate.

[0019] By adopting the above technical solution, the clamping bolt is located above the abutment plate. When the clamping bolt loosens, the screen will not fall directly off the support block. When the screen separates from the support block, the clamping bolt will lock the abutment plate, thereby preventing the screen from falling from a height and improving safety.

[0020] Optionally, the support block is provided with a sliding sleeve, the clamping bolt passes through the sliding sleeve and is threadedly connected to the sliding sleeve, the sliding sleeve has a limit groove, the support block is threadedly connected with a limit bolt, the limit bolt is inserted into the limit groove, and a swing rod is connected to the sliding sleeve.

[0021] By adopting the above technical solution, the limiting bolt is loosened, then the swing arm is rotated and the sliding sleeve is pushed towards the insertion block. Then the clamping bolt is tightened to fix the insertion block. Finally, the sliding sleeve is rotated so that the limiting bolt is aligned with the limiting groove, and the limiting bolt is tightened to restrict the movement of the sliding sleeve. By moving the sliding sleeve, the rotation of the clamping bolt can be reduced, which improves the installation efficiency of the support block and the screen.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The flipping component allows all the support blocks to flip and move to one end of the folding rod simultaneously. All the screens flip and are stacked together at one end of the folding rod. Finally, the folding rod is retracted, thereby reducing the space occupied by the dot matrix screen and facilitating the transportation of long dot matrix screens.

[0024] 2. The clamping bolt is located above the abutment plate. When the clamping bolt loosens, the screen will not fall directly off the support block. When the screen separates from the support block, the clamping bolt will lock the abutment plate, thereby preventing the screen from falling from a height and improving safety.

[0034] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0035] This application discloses a dot matrix screen with a flexible connecting hinge.

[0036] like Figure 1 , Figure 2 and Figure 3 The dot matrix screen with flexible connecting hinges includes a folding rod 2 and several screens 1. Several support blocks 3 are slidably mounted on the folding rod 2, and each support block 3 corresponds to one of the screens 1. The top surface of the support block 3 has an insertion groove 31. Each screen 1 has an insertion block 11, and each insertion block 11 is connected to an abutment plate 12. Both the abutment plate 12 and the insertion block 11 are inserted into their corresponding insertion grooves 31. A sliding sleeve 32 is slidably mounted on the support block 3, and the sliding sleeve 32 is threadedly connected to a clamping bolt 33, which clamps the screen. The insert block 11 and the clamping bolt 33 are located between the abutment plate 12 and the screen 1. The sliding sleeve 32 has a limiting groove 321, which is an L-shaped groove. One end of the limiting groove 321 is parallel to the clamping bolt 33, and the other end is perpendicular to the clamping bolt 33. The support block 3 is threaded with a limiting bolt 34, which abuts against the section of the limiting groove 321 perpendicular to the clamping bolt 33. The end of the sliding sleeve 32 away from the insert block 11 is connected to a swing rod 35. The folding rod 2 is provided with a flipping assembly 4 that allows several support blocks 3 to rotate simultaneously and move towards the top of the folding rod 2.

[0037] Rotate the rocker arm 35 and push the sliding sleeve 32 toward the insertion block 11, then tighten the clamping bolt 33 to fix the insertion block 11. Finally, rotate the sliding sleeve 32 to align the limiting bolt 34 with the limiting groove 321, tighten the limiting bolt 34 to restrict the movement of the sliding sleeve 32. By moving the sliding sleeve 32, the rotation of the clamping bolt 33 can be reduced, thus improving the installation efficiency of the support block 3 and the screen 1.

[0038] The clamping bolt 33 is located between the abutment plate 12 and the screen 1. When the clamping bolt 33 loosens, the screen 1 will not fall directly off the support block 3. When the screen 1 separates from the support block 3, the clamping bolt 33 will lock the abutment plate 12, thereby preventing the screen 1 from falling from a height and improving safety.

[0039] The flipping component 4 causes all the support blocks 3 to flip and move to one end of the folding rod 2 at the same time. All the screens 1 are flipped and stacked together at one end of the folding rod 2. Finally, the folding rod 2 is retracted, thereby reducing the space occupied by the dot matrix screen and facilitating the transportation of long dot matrix screens.

[0040] like Figure 1 The folding rod 2 includes several connecting rods 21, and the connecting rods 21 are provided with sliding grooves 22. The sliding grooves 22 of the several connecting rods 21 are interconnected. Adjacent connecting rods 21 are connected by hinges 23. The several hinges 23 are arranged alternately. One of the two adjacent hinges 23 is located on the front of the connecting rod 21, and the other is located on the back of the connecting rod 21.

[0041] like Figure 1 , Figure 4 and Figure 5 The flipping assembly 4 includes several first connecting rods 41. A support block 3 located at the top of the folding rod 2 is connected to a first gear 421. The first gear 421 is rotatably mounted on the folding rod 2. A third gear 43 is rotatably mounted on the folding rod 2. The third gear 43 meshes with the first gear 421 and is connected to a first connecting rod 41.

[0042] The first connecting rod 41 is rotatably connected to the second connecting rod 44, which is connected to another support block 3. The second connecting rod 21 is provided with a second gear 422, which slides along the sliding groove 22. The second gear 422 is rotatably connected to a sliding block 45, and the end of the second connecting rod 44 away from the first connecting rod 41 is connected to a support block 3.

[0043] Another third gear 43 is rotatably connected to the sliding block 45. The third gear 43 is connected to the corresponding first connecting rod 41. The third gear 43 meshes with the second gear 422. The first connecting rod 41 is rotatably connected to another second connecting rod 44. Through the above connection method of the first connecting rod 41 and the second connecting rod 44, the connecting rod structure is eventually formed.

[0044] The first connecting rod 41 located at the top of the folding rod 2 is controlled by a motor or other rotating tool to rotate. The first connecting rod 41 at the top of the folding rod 2 drives the third gear 43 to rotate, and the third gear 43 drives the first gear 421 to rotate, thereby causing the first support block 3 located at the top of the folding rod 2 to rotate. At the same time, the first connecting rod 41 at the top of the folding rod 2 lifts the second connecting rod 44 below it. The second connecting rod 44 moves towards the top of the folding rod 2 and rotates. The second connecting rod 44 drives the second gear 422 and the support block 3 connected to it to rotate, and the second connecting rod 44 drives the support block 3 to gradually move closer to the top of the folding rod 2.

[0045] At the same time, the second gear 422 drives another first gear 421 to rotate, the other first gear 421 drives the corresponding first link 41 to rotate, and the first link 41 continues to drive the corresponding second link 44 to rotate. Finally, rotating the first link 41 located at the top of the folding rod 2 allows all the screens 1 to be flipped and folded and moved towards the top of the folding rod 2. Finally, the folding rod 2 is retracted, thereby reducing the space occupied by the dot matrix screen.

[0046] The implementation principle of this application embodiment is as follows: When transporting the dot matrix screen, firstly rotate the first connecting rod 41 located at the top of the folding rod 2. Due to the linkage, all the first connecting rods 41 and the second connecting rods 44 move towards the top of the folding rod 2. At the same time, all the support blocks 3 flip and move towards the top of the folding rod 2, so that several screens 1 can be folded. Finally, several connecting rods 21 are folded and retracted, thereby reducing the space occupied by the dot matrix screen and facilitating the transportation of long dot matrix screens.

[0047] Example 2

[0048] Reference Figure 6 , Figure 7 and Figure 8 The difference between this embodiment and embodiment 1 is that the flipping assembly 4 includes a plurality of first rotating rods 46 and a plurality of second rotating rods 47. The support block 3 located at the top of the folding rod 2 is rotatably connected to the folding rod 2. A second rotating rod 47 is rotatably connected to the support block 3 located at the top of the folding rod 2. The second rotating rod 47 is connected to a connecting member 5 for driving the support block 3 located at the top of the folding rod 2 to rotate. The connecting member 5 is slidably disposed in the sliding groove 22. The connecting rod 21 is connected to the support block 3.

[0049] The second connecting rod 21 is rotatably connected to two first rotating rods 46. Each of the two first rotating rods 46 is connected to a support block 3. Both first rotating rods 46 are rotatably connected to a first rotating shaft 48. The first rotating shaft 48 is located in the sliding groove 22 and is slidably connected to the folding rod 2.

[0050] Two first rotating rods 46 are rotatably connected to another second rotating rod 47. The two first rotating rods 46 and the two second rotating rods 47 form a parallelogram structure. By repeatedly connecting them in the above manner, several first rotating rods 46 are parallel to each other, several second rotating rods 47 are parallel to each other, and the first rotating rods 46 and the second rotating rods 47 are interlocked and hinged to form several parallelogram structures.

[0051] Rotate the second rotating rod 47 located at the top of the folding rod 2 using a motor or other tools. The second rotating rod 47 drives the first rotating rod 46 connected to it to rotate around the corresponding first rotating shaft 48. At the same time, the first rotating rod 46 and the first rotating shaft 48 move towards the top of the folding rod 2. When the first rotating rod 46 rotates, it drives the support block 3 to rotate and move towards the top of the folding rod 2.

[0052] At the same time, when the first rotating rod 46 rotates, it drives the other connected second rotating rods 47 to rotate. The other second rotating rods 47 drive the other first rotating rods 46 to rotate, forming a whole linkage. When the second rotating rod 47 located at the top of the folding rod 2 rotates, it drives the connector 5 to make the support block 3 at the top of the folding rod 2 rotate, thereby realizing that all the screens 1 flip and fold and move towards the top of the folding rod 2. Finally, the folding rod 2 is retracted, thereby reducing the space occupied by the dot matrix screen.

[0053] Reference Figure 7 The connecting member 5 includes a second rotating shaft 51, a first support rod 52, and a second support rod 53. The second rotating shaft 51 is slidably disposed in the sliding groove 22. The second rotating shaft 51 is rotatably connected to the first support rod 52 and the second support rod 53. The end of the first support rod 52 away from the second rotating shaft 51 is hinged to the support block 3 located at the top of the folding rod 2. The end of the second support rod 53 away from the second rotating shaft 51 is hinged to the second rotating rod 47 located at the top of the folding rod 2.

[0054] When the second rotating rod 47 at the top of the folding rod 2 rotates, it pulls the second support rod 53 to rotate and move towards the top of the folding rod 2. The second support rod 53 drives the second rotating shaft 51 and the first support rod 52 to move towards the folding rod 2. At the same time, the first support rod 52 at the top of the folding rod 2 rotates and drives the support block 3 at the top of the folding rod 2 to rotate.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
