Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of road traffic sign manufacturing, and in particular to a frame profile for luminous road traffic signs, and also to a luminous road traffic sign. Background Technology
[0002] With the development of road traffic, the beautification of roads, and the increasing requirements for traffic safety, illuminated road traffic signs (also known as illuminated road traffic signs) are being used more and more. Illuminated road traffic signs can serve as normal daytime indicators or reflective indicators at night. At the same time, when the back light source panel emits light at night, it can also transmit light to make the front actively illuminate for indication.
[0003] Firstly, in existing technologies, the production of luminous road traffic signs, such as... Figure 13 As shown, panel X is first secured by three frame bars Y1, Y2, and Y3, and then the last frame bar Y4 is installed. Frame bar Y4 needs to be pushed in from the side (in the direction of the arrow in the diagram), covering the rightmost edge of panel X within frame bar Y4. This process makes it difficult to push frame bar Y4 in if the uncovered edge of panel X deforms (especially for large illuminated road traffic signs of several square meters or more, where panel deformation is more likely). This not only prolongs production time and reduces work efficiency but may also lead to significant product waste and high production costs. Furthermore, this frame structure and process make it impossible to quickly and cost-effectively replace the sign panel. Imagine that under these structural and process limitations, replacing the panel would require removing the entire sign and replacing it entirely.
[0004] Secondly, in the existing technology, the back panel of some luminous road traffic signs is a single piece of metal plate. Once maintenance is required inside the sign (such as replacing the light panel or repairing the wiring), the sign can only be removed to the ground for maintenance. Otherwise, working at height is not only inconvenient but also very dangerous.
[0005] Thirdly, some existing technologies divide the sign's back panel into multiple pieces, with back panel mounting plates on both the sign's frame rod and support rod. These multiple back panels are then supported and fixed onto these mounting plates. The mounting methods include using screws or rivets to detachably fix the back panels, or using adhesive, or a combination of screws and adhesive. This allows for the removal of the corresponding back panel for maintenance. However, through actual market testing and repeated trials, it has been found that this method still has significant technical problems:
[0006] 1. If adhesive bonding is used, to ensure structural strength, strong adhesive must be applied to both the contact surfaces of the back panel and the back panel mounting plate, and the back panel must be firmly glued to the mounting plate. This strong adhesive method makes it difficult to easily and quickly remove and separate the strong adhesive when a back panel needs to be removed at a height for quick maintenance. Often, forcibly pulling apart the back panel will damage or deform it, making it no longer flat or intact. This makes it very difficult to reinstall the back panel after maintenance, increasing the operation time and cost. In particular, due to the layered fixing method of the slide rails, external suspension rods, and horizontal thick fixing rods, the slide rails, external suspension rods, and horizontal thick fixing rods installed on the back panel in sequence will obstruct the back panel. This intricate mesh structure makes the operating space very limited, so removing the adhesive before opening the back panel for maintenance at a height remains very difficult.
[0007] 2. If screws or rivets are used, removing them requires an electric screwdriver and other tools. However, due to the layered fixing method of the slide rails, external suspension rods, and horizontal thick fixing rods, these components, stacked on the back panel, obstruct the back panel. This complex mesh structure severely limits the operating space, making it extremely difficult to remove multiple screws or rivets one by one at a height before opening the back panel for maintenance. If rivets are used, after removal, the original rivet holes on the back panel and mounting plate cannot be re-drilled; rivets must be driven into other areas. This results in numerous rivet holes on the back panel and mounting plate, affecting sealing and stability. Furthermore, due to the sign's structure and layout, many areas cannot be re-riveted, making the back panel installation unstable and severely impacting the sign's structural integrity and future installation capabilities.
[0008] 3. In this technology, two adjacent back panels are first overlapped and then glued together. This results in several drawbacks: firstly, the back panels lack flatness and aesthetic appeal; secondly, it also presents the aforementioned problem of difficulty in removing the strong adhesive for quick disassembly and maintenance; thirdly, this structure weakens the support and structural stability of the back panels, ultimately leading to poor overall structural stability of the sign, affecting its lifespan and traffic safety; and fourthly, the slide rails, external suspension rods, and horizontal thick fixing rods sequentially installed on the back panels obstruct the back panels, and this intricate mesh structure severely limits the operating space.

DETAILED DESCRIPTION
[0045] The utility model will be made further detailed description in combination with the description and specific embodiments of the drawings.
[0046] As Figures 1 to 12 As shown in the figure, the frame profile for the light-emitting road traffic sign of the embodiment can fix the panel 1 and the back plate 2 of the light-emitting road traffic sign, comprising the main frame profile 3 and the cover plate frame profile 4 which are detachably combined and installed, the cover plate frame profile 4 is provided with a bending plate 41 along the axial direction, the cover plate frame profile 4 and the main frame profile 3 are provided with the second quick-release fixing structure 5 at the contact position, when the panel 1 is carried on the main frame profile 3 during the sign manufacturing, the cover plate frame profile 4 is fixed on the main frame profile 3 through the second quick-release fixing structure 5, so as to clamp the panel 1 in the limiting groove between the bending plate 41 and the main frame profile 3 (the limiting groove is shown in the position of G in the figure).
[0047] It needs to be specially pointed out that the second quick-release fixing structure 5 is established on the cover plate frame profile 4 and the main frame profile 3 at the same time, that is, the cooperation of the cover plate frame profile 4 and the main frame profile 3 will form the most complete second quick-release fixing structure 5.
[0048] The specific implementation principle is as follows:
[0049] Mode one: taking the square sign as an example, it has four frame profiles. During the square sign manufacturing, the four main frame profiles 3 are connected with each other to form a square frame, then the panel 1 is carried on the four main frame profiles 3, only one cover plate frame profile 4 is installed on each main frame profile 3 through the second quick-release fixing structure 5, the four sides of the panel 1 are clamped and limited in the limiting groove between the bending plate 41 and the main frame profile 3 (the limiting groove is shown in the position of G in the figure), so as to fix the panel 1 on the frame (at this time, in order to seal, a layer of waterproof glue can be applied on the joint surface).
[0050] Mode two: taking the square sign as an example, it has four frame profiles. During the square sign manufacturing, the four main frame profiles 3 are connected with each other to form a square frame, then one cover plate frame profile 4 is installed on each of the three main frame profiles 3 through the second quick-release fixing structure 5, that is, an open shape without the cover plate frame profile 4 at one end is formed, then the panel 1 is pushed into the three limiting grooves formed by the cooperation of the three main frame profiles 3 and the three cover plate frame profiles 4 from the opening. Finally, the remaining one cover plate frame profile 4 is installed on the remaining one main frame profile 3 through the second quick-release fixing structure 5. At this time, the four sides of the panel 1 are clamped and limited in the limiting groove between the bending plate 41 and the main frame profile 3, so as to fix the panel 1 on the frame (at this time, in order to seal, a layer of waterproof glue can be applied on the joint surface).
[0051] When panel 1 needs to be replaced, the entire sign can be removed without removing the entire sign. Instead, the four cover plate frame profiles 4 can be easily removed directly using the special design of the second quick-release fixing structure 5, allowing panel 1 to be replaced. Since the four main frame profiles 3 are interconnected to form a square side frame, removing the four cover plate frame profiles 4 will not affect the overall structure and stability of the sign.
[0052] Firstly, the frame profile for luminous road traffic signs of this utility model, due to its special structure, while still covering the panel 1, completely overturns the existing installation method of sign panels. This eliminates the need for the panel to be squeezed into the existing frame, making installation particularly convenient and quick. Especially when producing large-area signs, the original manufacturing method is very difficult, but with this frame profile, manufacturing becomes extremely simple.
[0053] Secondly, the frame profile of the luminous road traffic sign of this utility model has a special structure, which overturns the existing technology that cannot quickly and cost-effectively replace the panel 1. It can realize high-altitude operation and convenient panel replacement, greatly reducing the cost of replacement and maintenance.
[0054] The second quick-release fixing structure 5 will be explained in detail below.
[0055] Based on the above embodiments and disclosed technical features, this utility model further provides multiple embodiments of the second quick-release fixing structure 5. It should be noted that the scope of protection of this utility model is not limited to the following embodiments.
[0056] like Figures 1 to 3 As shown in the specific embodiment 1, the cover plate frame profile 4 includes a cover plate 42 covering the top surface of the main frame profile 3. The cover plate 42 extends beyond the main frame profile 3 and is bent to form a bent plate 41. The second quick-release fixing structure 5 includes a matching limiting groove 51 and a limiting rib 52. The limiting groove 51 is formed along the axial direction of the main frame profile 3 on the top surface of the main frame profile 3. The limiting rib 52 protrudes along the axial direction of the cover plate 42 on the bottom surface of the cover plate 42. During installation, the limiting rib 52 is inserted from the side into the limiting groove 51 to detachably fix the cover plate 42 to the top surface of the main frame profile 3. As shown in the figure, the limiting rib 52 has a large end, allowing it to be inserted from the side and locked within the limiting groove 51. Figure 12As illustrated, since panel 1 has a certain thickness, the limiting groove between the bent plate 41 and the main frame profile 3 (the limiting groove is shown as position G in the figure) also has a certain thickness (i.e., width). Of course, in other embodiments, if a relatively thin panel 1 is used, the limiting groove between the bent plate 41 and the main frame profile 3 should also be correspondingly narrower. In short, the panel 1 can be precisely clamped and covered within the limiting groove between the bent plate 41 and the main frame profile 3.
[0057] like Figures 4 to 6 As shown in the specific embodiment 2, the cover plate frame profile 4 includes a cover plate 42 covering the top surface of the main frame profile 3. The side of the cover plate 42 extending outside the main frame profile 3 is bent to form a bent plate 41. The second quick-release fixing structure 5 includes a limiting groove 51 and multiple cooperating limiting sliders 53 and screws 54. The limiting sliders 53 have screw holes for fixing the screws 54. The limiting groove 51 is opened along the axial direction of the main frame profile 3 on the top surface of the main frame profile 3. The multiple limiting sliders 53 are slidably installed in the limiting groove 51 to allow the screws 54 to pass through the cover plate 42 and be fixed on the limiting sliders 53, so that the cover plate 42 is detachably fixed to the top surface of the main frame profile 3. The limiting sliders 53 can be pre-installed in the limiting groove 51, or an elastic limiting slider design can be used to temporarily squeeze into the limiting groove 51.
[0058] In this embodiment, the cover plate 42 has a countersunk hole 421 for screws 54 to pass through and fix it. This makes it aesthetically pleasing.
[0059] like Figures 7 to 9 As shown in embodiment 3, the cover plate frame profile 4 includes a flap 43 arranged axially along the main frame profile 3. The second quick-release fixing structure 5 includes a hinge groove 55 opened axially along the main frame profile 3 and a hinge portion 56 arranged axially along the flap 43. The hinge portion 56 is located on one side of the flap 43, and the other side of the flap 43 is bent to form a bent plate 41. The hinge portion 56 is confined within the hinge groove 55. During installation, the flap 43 drives the bent plate 41 to flip outward to facilitate the installation of the panel 1, and then drives the bent plate 41 to flip back inward to clamp the panel 1 between the bent plate 41 and the main frame profile 3. This structure allows for the application of a layer of waterproof adhesive between the bent plate 41 and the panel 1 after the bent plate 41 is flipped back inward, which enhances stability and provides waterproofing.
[0060] In the embodiment, the second quick-release fixing structure 5 includes an elastic member 57 arranged in the hinge groove 55, and is used to abut against the hinge portion 56 to form a limit when the flap 43 drives the bent plate 41 to turn back inward. In the embodiment, the elastic member 57 includes a protruding elastic strip. Once the bent plate 41 turns back inward, the hinge portion 56 will press the elastic strip, i.e., the elastic strip will abut against the hinge portion 56 to form a limit.
[0061] As shown in the drawings, in the embodiment, the main frame profile 3 is provided with a bearing plate 31 along the axial direction for bearing the back plate 2. A mounting sliding groove 32 is also provided near the bearing plate 31 along the axial direction. The mounting sliding groove 32 is provided with a plurality of slidable pressing members 6 for detachably pressing and fixing the back plate 2 on the bearing plate 31 so that the back plate 2 can be quickly removed for maintenance. Figures 1 to 12
[0062] During manufacturing, the back plate 2 is first borne on the bearing plate 31 of the main frame profile 3, and then is pressed and fixed on the main frame profile 3 by the plurality of slidable pressing members 6 of the mounting sliding groove 32, and then is hoisted and fixed to the road side. This makes the panel 1 easy to install, and the back plate 2 easy to manufacture and install.
[0063] When the inside of the light-emitting road traffic sign needs to be maintained, the construction personnel can directly ascend to the air by the elevator without unloading the heavy light-emitting road traffic sign, and then easily loosen the corresponding pressing member 6, and then the back plate 2 can be removed for quick, targeted and accurate maintenance. When the maintenance is completed, the back plate 2 is installed back in the original way. That is to say, each pressing member 6 can be restored to the original installation position for installation. It should be noted that, in construction, in order to further ensure the sealing, a thin elastic layer material can be arranged on the edge of the back plate 2 or the bearing plate 31, so that the elastic layer is pressed when the back plate 2 is pressed on the bearing plate 31, and the sealing between the two is ensured. Further, a waterproof glue can be applied on the outer surface at the contact position between the back plate 2 and the main frame profile 3. The waterproof glue is applied on the outer surface, rather than being fixed between the back plate and the bearing plate 31 as in the prior art. This makes it easy to scrape off the waterproof glue on the outer surface by using a scraper or the like when the back plate 2 needs to be removed.
[0064] Through the above special scientific design, the following advantages are achieved:
[0065] First, the special main frame profile 3 and the pressing member 6 are arranged, which completely overturns the fixing form of the existing back plate, makes the panel 1 easy to install, and the back plate 2 easy to manufacture and install. Meanwhile, the corresponding back plate 2 can be easily and quickly removed and reset for the area needing maintenance, which can realize quick, targeted and accurate maintenance, shortens the working time, improves the working efficiency, and greatly reduces the maintenance cost.
[0066] Secondly, whether the back plate 2 is removed or reinstalled, no damage and deformation of the back plate 2 will be caused, and no punching of the main frame profile 3 is required, and each pressing part 6 can be restored to the original installation position for installation, effectively ensuring the integrity of each component, thereby effectively ensuring the sealing, stability and safety of the sign as a whole.
[0067] Thirdly, the design of the slidable pressing part 6 not only facilitates the later maintenance and disassembly, but also greatly facilitates the early sign production. The pressing part 6 with a slidable adjusting position can be flexibly fixed and installed according to actual needs by selecting different numbers of pressing parts 6 and adjusting different positions of the pressing parts 6 when finally pressing and fixing, so that the production is convenient, fast and stable.
[0068] In the embodiment, the pressing part 6 includes a sliding part 61 sliding in the installation sliding groove 32, the sliding part 61 is provided with an installation part 62 extending from the slot opening of the installation sliding groove 32, and the installation part 62 is provided with a screw rod part 63 for pressing the screw rod part 63 on the back plate 2 by rotating. Of course, in other embodiments, other forms can also be used, as long as they can slide in the installation sliding groove 32 and press and fix the back plate 2 on the main frame profile 3, which belongs to the protection range of the utility model.
[0069] As shown in Figures 1 to 12 , the light-emitting road traffic sign of the embodiment includes three or more frame profiles for the light-emitting road traffic sign according to any one of the above, and the three or more frame profiles form an outer frame of the light-emitting road traffic sign.
[0070] As shown in Figures 1 to 12 , the embodiment also includes one or more connecting elbows 7, and at least two adjacent frame profiles are connected by the connecting elbow 7.
[0071] Although the utility model has been disclosed as above with the preferred embodiments, it is not intended to limit the utility model. Any skilled person in the art can make many possible changes and modifications to the utility model technical solution or modify it into equivalent embodiments with equivalent changes without departing from the scope of the utility model technical solution. Therefore, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the utility model technical solution shall fall within the protection scope of the utility model technical solution.
