Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to an embedded hinge and folding LED display advertising machine. Background Technology

[0002] Traditional modular front-maintenance LED display advertising machines are too bulky, resulting in excessive internal packaging space and high shipping costs. Moreover, the modules need to be removed during packaging and transportation; otherwise, vibrations during transportation may cause the modules to detach from the casing, resulting in module damage. Utility Model Content

[0003] Based on this, an embedded hinge and folding LED display advertising machine that improves the above-mentioned defects is provided. The advertising machine is divided into two parts and folded, thereby reducing the height of the packaging and reducing the shipping cost. When folding, the light-emitting surface folds together. Through the bending stroke of the hinge design, a gap is reserved for placing shock-absorbing cotton. The gap is filled with shock-absorbing cotton of the corresponding thickness to prevent the module from loosening or falling off during transportation.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: an embedded hinge, including a first fixed base, a second fixed base, a first hinge, and a second hinge. The second hinge is rotatably connected to the second fixed base. The first fixed base and the second fixed base have the same structure and are arranged in a mirror image symmetrical arrangement. Both the first fixed base and the second fixed base are provided with mounting holes and fixed base shaft holes. The first hinge and the second hinge have the same structure and are both composed of multiple arched hinges. The first hinge and the second hinge are stacked and assembled in opposite directions. Both the first hinge and the second hinge are provided with mounting shaft holes, central shaft holes, and connecting shaft holes. The mounting shaft hole on the first hinge corresponds to the fixed base shaft hole on the first fixed base and contains a fixed base shaft. Similarly, the mounting shaft hole on the second hinge corresponds to the fixed base shaft hole on the second fixed base and contains a fixed base shaft. The central shaft holes on the first hinge and the second hinge correspond to each other and contain a rotating central shaft. The connecting shaft holes on the first hinge and the second hinge are respectively provided with connecting shafts.

[0005] In use, the first and second fixing seats can be embedded and fixed into the opposite end faces of the two connecting parts to be rotated and connected through the mounting holes, such as two LED display modules to be rotated and folded. In this way, the first hinge end can rotate relative to the first fixing seat and the second hinge end can rotate relative to the second fixing seat through the fixing seat shaft. The relative rotation of the first and second hinges can be achieved through the rotating central shaft, thereby realizing the relative rotation of the two connecting parts. In addition, the reverse staggered stacking assembly of the first and second hinges effectively improves the high-precision operation of the hinge during the flipping process. The first and second hinges fit more tightly, the force is more even, and the rotational stability is high. The arched structure design of the first and second hinges ensures that they will not interfere with the two connecting parts during rotation. That is, the bottom of the first and second hinges will not abut against the connecting parts, and will not cause wear and tear on the connecting parts.

[0006] Preferably, guide grooves are provided on both inner walls of the first and second fixed seats, and guide shaft holes are provided at the ends of the first and second hinges, with guide shafts installed in the guide shaft holes. The two ends of the guide shafts are placed in the guide grooves and can move up and down relative to the guide grooves. When the first and second fixed seats are folded 180° relative to each other, the guide shafts abut against the top wall of the guide grooves. The cooperation between the guide shafts and the guide grooves makes the hinge rotation more stable, and the guide grooves achieve 180° limit of rotation of the first and second fixed seats, preventing them from over-rotating.

[0007] Preferably, hinge positioning grooves are provided on the outer side walls of the first and second fixed seats, and positioning protrusions are provided on the inner side of the ends of the first and second hinges. The positioning protrusions can slide up and down in the hinge positioning grooves. In conjunction with the reverse staggered stacking assembly of the first and second hinges, they are rotated in a specified trajectory, further ensuring the rotational accuracy and rotational stability of the hinge.

[0008] Preferably, both the first and second fixed seats have protruding limiting slopes at their upper ends. When the first and second fixed seats are folded 180° relative to each other, the bottom of the first and second hinges fits precisely with the limiting slopes, limiting the travel of the first and second hinges and preventing them from rotating excessively.

[0009] Preferably, the upper ends of the inner sidewalls of the first fixed seat and the second fixed seat are provided with clearance grooves. When the first fixed seat and the second fixed seat are closed, the rotating central shaft protrudes from both ends of the first hinge and the second hinge and is placed in the clearance groove.

[0010] This utility model also provides a foldable LED display advertising machine, including a first display module, a second display module, and any one of the aforementioned embedded hinges. Both the first and second display modules include a housing for telecommunication connection and a light-emitting module. An embedded mounting base is provided at the end of each housing. Each mounting base has a positioning hole and a mounting screw hole. Positioning posts are provided at the bottom of both the first and second mounting bases. The positioning posts are inserted into the positioning holes for positioning. The mounting holes and mounting screw holes are axially aligned vertically and fixed by bolts. When folded for storage or transportation, the hinge is... The embedded hinge rotates, causing the light-emitting modules of the first and second display modules to fold towards each other on one side. When the embedded hinge rotates 180°, the two light-emitting modules are opposite and parallel. Due to the arched structure design of the first and second hinges, the first and second hinges will not interfere with the light-emitting modules. That is, the light-emitting modules will not be worn during the rotation. A filling gap is reserved between the two light-emitting modules. Shock-absorbing cotton can be filled in the gap during folding, storage or transportation to protect the light-emitting modules and avoid the risk of them being bumped or falling.

[0011] Preferably, the upper end of the second display module is provided with a hook lock, and the connection end between the first display module and the second display module is provided with a locking rod. The hook lock can be hooked onto the locking rod. When the first display module and the second display module are unfolded and used, they are fixed to the locking rod by the hook lock. In addition, the locking rod can be linked with the hook lock switch. By turning the hook lock switch with a wrench or other tools, the locking rod can be rotated, thereby controlling the locking and unlocking of the hook and the locking rod.

[0012] The beneficial effects of this utility model are:

[0013] The aforementioned embedded hinge, in actual use, can be embedded in two rotating connecting parts to achieve the rotating and folding function of the connecting parts. The reverse staggered stacking of the first and second hinges effectively improves the high-precision operation of the hinge during the flipping process, resulting in a tighter fit, more even force distribution, and high rotational stability. The arched structure design of the first and second hinges ensures that they do not interfere with the two connecting parts during rotation; that is, the bottoms of the first and second hinges do not come into contact with the connecting parts, preventing wear and tear. The guide groove and guide shaft cooperate to achieve 180° rotation limit for the first and second fixed seats, preventing excessive rotation. Furthermore, when the hinge rotates to 180°, the limiting inclined surface abuts against the bottom surfaces of the first and second hinges, preventing excessive rotation.

[0014] The aforementioned foldable LED display advertising machine achieves its rotation and folding function through the use of embedded hinges. When folding for storage or transportation is required, the embedded hinges allow it to fold, reducing storage space and transportation costs. Furthermore, the light-emitting modules do not need to be disassembled during transportation; shock-absorbing cotton can be filled between the light-emitting modules to effectively prevent damage and detachment, thus improving packaging space utilization. Through the arched structure design of the first and second hinges, the first and second hinges will not interfere with the light-emitting modules, meaning that no wear or tear will occur to the light-emitting modules during rotation.

[0028] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figures 1 to 6As shown, this utility model provides an embedded hinge, including a first fixed base 1, a second fixed base 2, a first hinge 3, and a second hinge 4. The second hinge 4 is rotatably connected to the second fixed base 2. The first fixed base 1 and the second fixed base 2 have the same structure and are arranged in a mirror symmetrical manner. Both the first fixed base 1 and the second fixed base 2 are provided with mounting holes 5 and fixed base shaft holes 6. The first hinge 3 and the second hinge 4 have the same structure, each composed of multiple arched hinges, and the first hinge 3 and the second hinge 4 are stacked and assembled in opposite directions. The first hinge 3 and the second hinge 4 have... Each hinge 3 has an assembly shaft hole 10, a central shaft hole 12, and a connecting shaft hole 14. The assembly shaft hole 10 on the first hinge 3 corresponds to the fixing shaft hole 6 on the first fixing seat 1 and contains a fixing seat shaft 11. Similarly, the assembly shaft hole 10 on the second hinge 4 corresponds to the fixing shaft hole 6 on the second fixing seat 2 and contains a fixing seat shaft 11. The central shaft holes 12 on the first hinge 3 and the second hinge 4 correspond to each other and contain a rotating central shaft 13. The connecting shaft holes 14 on the first hinge 3 and the second hinge 4 respectively contain a connecting shaft 15.

[0032] In use, the first fixing seat 1 and the second fixing seat 2 can be embedded and fixed into the opposite end faces of the two connecting parts to be rotated and connected through the mounting holes 5, such as two LED display modules to be rotated and folded. In this way, the first hinge 3 can rotate relative to the first fixing seat 1 and the second hinge 4 can rotate relative to the second fixing seat 2 through the fixing seat shaft 11. The relative rotation of the first hinge 3 and the second hinge 4 can be achieved through the rotating central shaft 13, thereby realizing the relative rotation of the two connecting parts. In addition, the reverse staggered stacking assembly of the first hinge 3 and the second hinge 4 effectively improves the high-precision operation of the hinge during the flipping process. The first hinge 3 and the second hinge 4 fit more tightly, the force is more even, and the rotational stability is high. The arched structure design of the first hinge 3 and the second hinge 4 ensures that they will not interfere with the two connecting parts during rotation. That is, the bottom of the first hinge 3 and the second hinge 4 will not abut against the connecting parts, and will not cause wear and tear on the connecting parts.

[0033] Furthermore, guide grooves 8 are provided on both inner walls of the first fixing seat 1 and the second fixing seat 2, and guide shaft holes 16 are provided at the ends of the first hinge 3 and the second hinge 4, with guide shafts 17 installed in the guide shaft holes 16. The two ends of the guide shafts 17 are positioned within the guide grooves 8 and can move up and down relative to the guide grooves 8. Figure 5 As shown, when the first fixed seat 1 and the second fixed seat 2 are folded 180° relative to each other, the guide shaft 17 abuts against the top wall of the guide groove 8. The guide shaft 17 and the guide groove 8 cooperate to make the hinge rotate more smoothly, so that the hinge can complete the flip from 0° to 180° in the specified trajectory. The guide groove 8 also realizes the 180° limit of the rotation of the first fixed seat 1 and the second fixed seat 2, avoiding excessive rotation.

[0034] Furthermore, hinge positioning grooves 7 are provided on the outer side walls of the first fixed base 1 and the second fixed base 2, and positioning protrusions 18 are provided on the inner side of the ends of the first hinge 3 and the second hinge 4. The positioning protrusions 18 can slide up and down in the hinge positioning grooves 7. In conjunction with the reverse staggered stacking assembly of the first hinge 3 and the second hinge 4, they slide in a designated trajectory, further ensuring the rotational accuracy and rotational stability of the hinge.

[0035] Furthermore, both the first fixing seat 1 and the second fixing seat 2 have protruding limiting inclined surfaces 9 at their upper ends. When the first fixing seat 1 and the second fixing seat 2 are folded 180° relative to each other, as... Figure 6 As shown, the bottom of the first hinge 3 and the second hinge 4 are exactly in contact with the limiting inclined surface 9, which restricts the travel of the first hinge 3 and the second hinge 4 and prevents the first hinge 3 and the second hinge 4 from rotating excessively.

[0036] Furthermore, both the upper ends of the inner sidewalls of the first fixing seat 1 and the second fixing seat 2 are provided with clearance grooves 19. When the first fixing seat 1 and the second fixing seat 2 are closed, such as Figure 3 As shown, the rotating central shaft 13 protrudes from both ends of the first hinge 3 and the second hinge 4 and is placed in the clearance groove 19.

[0037] like Figures 7 to 11 As shown, this utility model also provides a foldable LED display advertising machine, including a first display module 20, a second display module 21, and any of the above-mentioned embedded hinges. Both the first display module 20 and the second display module 21 include a housing 28 for telecommunication connection and a light-emitting module 29. An embedded mounting base 22 is provided at the end of each housing 28. Each mounting base 22 has a positioning hole 24 and a mounting screw hole 25. Positioning posts 23 are provided at the bottom of both the first fixing base 1 and the second fixing base 2. The positioning posts 23 are inserted into and positioned with the positioning holes 24. The mounting holes 5 and the mounting screw holes 25 are axially aligned vertically and fixed by bolts. When folded for storage or transportation, the embedded hinge rotates, causing the light-emitting modules 29 of the first display module 20 and the second display module 21 to fold towards each other on one side. Figure 9 As shown, when the embedded hinge rotates 180°, the two light-emitting modules 29 are opposite and parallel. Due to the arched structure design of the first hinge 3 and the second hinge 4, the first hinge 3 and the second hinge 4 will not interfere with the light-emitting modules 29. That is, the light-emitting modules 29 will not be worn during the rotation. A filling gap will be reserved between the two light-emitting modules 29. Shock-absorbing cotton 30 can be filled in the gap during folding, storage or transportation to protect the light-emitting modules 29 and avoid the risk of them being bumped or falling.

[0038] Furthermore, the upper end of the second display module 21 is provided with a hook lock 26, and the connection end between the first display module 20 and the second display module 21 is provided with a locking rod (not shown in the figure). The hook lock 26 can be hooked onto the locking rod. When the first display module 20 and the second display module 21 are unfolded for use, such as Figure 10 , Figure 11 As shown, the locking lever is fixed to the hook 26. Furthermore, the locking lever 26 can be linked to the hook lock switch 27. By turning the hook lock switch 27 with a wrench or other tool, the locking lever 26 is rotated, thereby controlling the locking and unlocking of the hook 26 and the locking lever. It should be noted that the hook 26 can also be located in the first display module 20, in which case the locking lever is correspondingly located in the second display module 21, as long as it ensures that the first display module 20 and the second display module 21 can be unfolded and fixed for use.
