Description
Technical Field
[0001] This utility model relates to the field of power safety warning technology, and in particular to a self-illuminating power sign. Background Technology
[0002] Power system signs are important safety devices used in power systems for warning, indicating, and transmitting information. They are widely used in substations, distribution rooms, transmission lines, construction sites, and other locations. Their main function is to clearly indicate key information such as "Do Not Close," "Danger of Electricity," and "Under Repair" during equipment inspection, maintenance, or troubleshooting, thereby ensuring the personal safety of workers and the standardized operation of the power system.
[0003] Utility model patent CN 219591061 U discloses a self-illuminating electric sign that achieves continuous illumination at night by using a luminescent film. It employs a structure with a movable shell and a fixed shell for easy replacement of the sign content, solving the problems of inconvenience, easy detachment, and poor nighttime warning effect associated with traditional adhesive labels. This solution represents a significant advancement in improving the convenience of information replacement and nighttime visibility.
[0004] However, this technical solution still has significant drawbacks: its structural design lacks an adjustable height support mechanism, and the signage as a whole lacks a flexible and stable support method, relying solely on fixed brackets or temporary suspension. It cannot adjust the height and angle according to the actual usage environment (such as different ground heights, viewing angles, and site layouts). In complex outdoor terrain or scenarios requiring long-distance warnings, the visibility of the signage is greatly reduced. Utility Model Content
[0005] The purpose of this utility model is to provide a self-illuminating electric sign that solves the problem that the existing technology does not have an adjustable height support mechanism in its structural design, and the overall sign lacks a flexible and stable support method, relying only on fixed brackets or temporary suspension, and cannot adjust the height and angle according to the actual use environment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A self-illuminating electric sign includes a base, a mounting frame, and a sign. The mounting frame is connected to the top of the base via a vertical lifting structure. One side of the mounting frame has a mounting groove adapted to the sign. Both sides of the inner wall of the mounting groove have insertion slots. Each insertion slot has a limiting plate movably connected inside. One side of the limiting plate is fixedly connected to a positioning plate that is detachably connected to the side wall of the mounting frame.
[0008] Preferably, the base has two detachable casters on one side and a pull handle fixedly connected to the other side.
[0009] Preferably, a positioning screw with one end threaded through the positioning plate is provided on one side of the positioning plate, and one end of the positioning screw is fixedly connected to the side wall bolt of the mounting frame.
[0010] Preferably, the pull handle is made of metal, and the outer ring of the pull handle is connected to a rubber sleeve.
[0011] Preferably, a handle is provided on one side of the positioning plate, and the handle is bolted to the side wall of the positioning plate.
[0012] Preferably, the vertical lifting structure includes a top plate and a bottom plate. The bottom two sides of the top plate are connected to the top of the bottom plate through lifting cylinders. Lifting rods are fixedly connected to the bottom two sides of the mounting frame. One end of the lifting rod slides through the top plate and slides into the interior of the adjacent lifting cylinder. The bottom plate is fixedly connected to the top of the base. A push cylinder is installed at the center of the top of the bottom plate. The output end of the push cylinder is connected to the bottom of the mounting frame.
[0013] This utility model has the following beneficial effects: By setting a vertical lifting structure between the base and the mounting frame, the entire signage assembly can be height-adjusted according to different site environments such as slopes, uneven ground, or specific viewing angles. This overcomes the limitations of traditional fixed supports that cannot adapt to complex terrain, improving the versatility and visibility of the signage in various application scenarios. Especially in situations requiring long-distance identification, it can raise the signage to a more conspicuous position, avoiding the risk of misjudgment due to obstruction or low line of sight. Simultaneously, the mounting groove on the mounting frame, combined with the limiting plate in the insertion slot and the detachable positioning... The plate forms a stable and easy-to-operate quick-change mechanism. Compared with the prior art that only relies on the cooperation of the movable shell and the fixed shell, this solution not only achieves a firm clamping of the sign, but also enhances the anti-interference ability of the overall structure through the secondary locking mechanism of the positioning plate, preventing the limit plate from accidentally loosening due to vibration or external force during long-term use, thus improving the safety and reliability of use. This structural design allows the replacement of the sign to be completed without the intervention of tools, and the disassembly and installation can be completed by manual operation, which greatly shortens the information switching time and meets the work rhythm of frequent changes in warning content in power sites.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] Example 1
[0023] Please see Figure 1-5 As shown, a self-illuminating electric signboard of this embodiment includes a base 1, a mounting frame 2, and a signboard 3. The mounting frame 2 is connected to the top of the base 1 through a vertical lifting structure. A mounting groove 10 adapted to the signboard 3 is provided on one side of the mounting frame 2. Insertion grooves 8 are provided on both sides of the inner wall of the mounting groove 10. A limiting plate 9 is movably connected inside each insertion groove 8. A positioning plate 12 that is detachably connected to the side wall of the mounting frame 2 is fixedly connected to one side of the limiting plate 9.
[0024] When using this self-illuminating power sign, first place the base 1 stably on the ground in the power work area where warnings are needed. Depending on the actual terrain, such as slopes or uneven surfaces, the overall height of the mounting frame 2 can be flexibly adjusted using the vertical lifting structure between the base 1 and the mounting frame 2. This vertical lifting structure allows the mounting frame 2 to move up and down vertically, and after adjusting to a suitable height, a locking mechanism maintains its stable position. This ensures that the sign 3 installed on it is at the optimal visibility height within the worker's line of sight, especially in complex environments requiring long-distance warnings or where visibility is obstructed, such as the perimeter of substations, transmission line construction areas, or temporary repair sites, effectively improving visibility. The readability and warning function of the signage information; after the height adjustment is completed, the sign 3 with the required display content is horizontally inserted into the opening of the mounting groove 10 on one side of the mounting frame 2. The size of the mounting groove 10 is adapted to the shape of the sign 3 to ensure basic positioning support after insertion; as the sign 3 is pushed in, its two side edges gradually enter the insertion groove 8 area provided in the inner wall of the mounting groove 10. At this time, the limiting plate 9, which is movably connected inside the insertion groove 8, undergoes elastic or sliding displacement after being squeezed by the side of the sign 3. After the sign 3 is fully in place, the limiting plate 9 is manually reset so that one side is re-attached to the side wall surface of the sign 3, forming a lateral limit to prevent the sign 3 from loosening or slipping due to external vibration or wind; to further To enhance stability, the positioning plate 12 connected to the outer end of the limiting plate 9 is detachably connected to the side wall of the mounting frame 2. This connection can employ common structures such as screw fastening or snap-fit. The positioning plate 12's fixing constraint firmly confines the limiting plate 9 to the clamping position, preventing free movement and ensuring the sign 3 is securely clamped inside the mounting groove 10. When the on-site operating conditions change and the warning content needs to be replaced, simply disconnect the connection between the positioning plate 12 and the side wall of the mounting frame 2, such as by unscrewing the screws or loosening the snaps. Then, the limiting plate 9 can be manually moved outward from the insertion groove 8, disengaging it from the side wall of the sign 3. At this point, the sign 3 loses its clamping force and can be easily pulled out of the mounting groove 10. After replacing the new sign 3, the replacement operation can be completed by repeating the above steps of insertion, limiting, and fixing the positioning plate 12. The whole process does not require the use of special tools or disassembly of the entire sign structure, which greatly improves the efficiency of information updates and meets the actual needs of frequent changes in warning content at power maintenance sites. In addition, the sign 3 body is made of a material with light-storing properties or is covered with a luminous film. When exposed to natural light or ambient light sources for a long time during the day, it can absorb and store light energy and automatically release visible light at night or in dim light conditions to achieve a continuous self-luminous effect. This significantly enhances the visibility and warning function in low-light environments and ensures the effectiveness of safety warnings in the event of night work or sudden power outages.
[0025] Example 2
[0026] Please see Figure 1-5 As shown in this embodiment, a self-illuminating power sign has two detachable casters 14 on one side of the base 1 and a pull handle 15 fixedly connected to the other side. Specifically, through the cooperation of the two detachable casters 14 on one side of the base 1 and the pull handle 15 fixedly connected to the other side of the base 1, the casters 14 can be installed at the corresponding connection positions on the base 1 during use, enabling the entire sign to move. The operator can apply pulling force by holding the pull handle 15 to move the base 1 and the structure above it on the ground, facilitating rapid transfer between different work points. This is especially suitable for power construction sites where the warning position needs to be frequently changed. When fixed use is required, the casters 14 can be detached to ensure stable contact between the base 1 and the ground, avoiding accidental displacement caused by the rolling of the wheels. This achieves the effect of improving the overall mobility and on-site adaptability of the device, while also taking into account convenient transportation and stable operation.
[0027] The pull handle 15 is made of metal, and its outer ring is connected to a rubber sleeve. Specifically, by using metal to make the pull handle 15 and connecting it to a rubber sleeve, the metal provides sufficient structural strength to ensure that the pull handle 15 is not easily deformed or broken during frequent force dragging. The rubber sleeve on the outer ring increases the friction and comfort when gripping the hand, reduces the risk of slipping, and alleviates hand fatigue caused by long-term operation. It can maintain good grip performance, especially in rainy or humid environments, thus achieving the effect of improving operational safety and ergonomic experience while ensuring structural strength.
[0028] Example 3
[0029] Please see Figure 1-5 As shown in this embodiment, a self-illuminating electric signboard has a positioning screw 11 with one end threaded through the positioning plate 12 on one side. One end of the positioning screw 11 is fixedly connected to the side wall bolt of the mounting frame 2. Specifically, through the cooperation of the positioning screw 11 with one end threaded through the positioning plate 12 and the side wall bolt of the mounting frame 2, after the signboard 3 is inserted and initially clamped by the limiting plate 9, the positioning screw 11 is screwed into the threaded hole of the side wall of the mounting frame 2, so that it passes through the positioning plate 12 and is tightened, thereby firmly fixing the positioning plate 12 in the current position. This structure realizes a reliable connection between the positioning plate 12 and the mounting frame 2, enhances the clamping stability of the limiting plate 9 on the signboard 3, prevents the positioning plate 12 from loosening and falling off due to vibration or external force, and achieves the effect of improving the fixing firmness and connection durability of the signboard, ensuring that the warning information does not loosen during long-term use.
[0030] A handle 13 is provided on one side of the positioning plate 12. The handle 13 is fixedly connected to the side wall of the positioning plate 12 with bolts. Specifically, through the cooperation of the handle 13 on one side of the positioning plate 12 and the fixed connection of the handle 13 to the side wall of the positioning plate 12 with bolts, when replacing the sign 3, the operator can apply pulling force by holding the handle 13 to easily pull the positioning plate 12 outward as a whole, thereby driving the limiting plate 9 out of the insertion slot 8 and releasing the clamping constraint on the sign 3. This structure avoids the inconvenience of directly prying the positioning plate 12 by hand. Especially in low temperature, wearing gloves or limited space, the disassembly action can still be easily completed, achieving the effect of improving the convenience of sign replacement operation and human-machine interaction efficiency.
[0031] The vertical lifting structure includes a top plate 5 and a bottom plate 7. The bottom sides of the top plate 5 are connected to the top of the bottom plate 7 via lifting cylinders 4. Lifting rods are fixedly connected to the bottom sides of the mounting frame 2. One end of each lifting rod slides through the top plate 5 and slides into the adjacent lifting cylinder 4. The bottom plate 7 is fixedly connected to the top of the base 1. A push cylinder 6 is installed at the center of the top of the bottom plate 7. The output end of the push cylinder 6 is connected to the bottom of the mounting frame 2. Specifically, the vertical lifting structure includes a top plate 5 and a bottom plate 7. The bottom sides of the top plate 5 are connected to the top of the bottom plate 7 via lifting cylinders 4. The lifting rods on both sides of the bottom of the mounting frame 2 slide through the top plate 5 and slide into the lifting cylinders 4. 4. Internal sliding fit: The bottom plate 7 is fixedly connected to the top of the base 1, and a push cylinder 6 is installed at the center of the top of the bottom plate 7. The output end of the push cylinder 6 is connected to the bottom of the mounting frame 2. When the height needs to be adjusted, the push cylinder 6 is activated, and its output end extends and retracts, driving the mounting frame 2 to move vertically along the sliding path of the lifting rod and the lifting cylinder 4, so as to realize the smooth lifting and lowering of the mounting frame 2 and the sign 3. This structure replaces manual adjustment with pneumatic drive, which significantly reduces the labor intensity of operation and improves the accuracy and response speed of height adjustment. It is especially suitable for scenarios that require frequent height adjustment or single-person operation, and achieves the effect of improving the automation level of lifting operation, adjustment accuracy and overall ease of use.
[0032] When using this self-illuminating power sign, first determine the installation status of the casters 14 based on whether relocation is required on site. If it needs to be moved between multiple work points, the two casters 14 can be detachably connected to the corresponding interface on one side of the base 1. At the same time, ensure that the pull handle 15 on the other side is securely fixed. The pull handle 15 is made of metal to ensure structural strength, and a rubber sleeve is connected to its outer ring to improve grip comfort and anti-slip performance. The operator applies pull force by holding the pull handle 15 with both hands, using the casters 14 to achieve convenient movement of the entire device on the ground. This is suitable for scenarios such as substations and transmission line construction areas where the warning position needs to be frequently changed. After reaching the designated location, the casters 14 can be removed from the ground. 14. Remove the base from the base 1 to ensure stable contact between the base 1 and the ground, preventing accidental displacement due to wheel rolling. Then, activate the vertical lifting structure for height adjustment. This structure includes a bottom plate 7 fixedly connected to the top of the base 1. A push cylinder 6 is installed at the center of the top of the bottom plate 7. The output end of the push cylinder 6 extends upward and connects to the bottom of the mounting frame 2. Simultaneously, the top sides of the bottom plate 7 are connected to the bottom of the top plate 5 via lifting cylinders 4. Lifting rods are fixedly connected to the bottom sides of the mounting frame 2. One end of the lifting rod slides through the top plate 5 and extends into the adjacent lifting cylinder 4 to form a sliding fit. When the push cylinder 6 is activated, its output end extends and retracts, causing the entire mounting frame 2 to move along the lifting rod and lifting cylinder 4. The guide path smoothly rises or falls, enabling precise vertical adjustment of the mounting frame 2. This allows for adjustment of the display height of the sign 3 according to the terrain, such as slopes, potholes, or the eye level of workers, ensuring optimal visibility, especially in long-distance warnings or complex environments, significantly improving recognition effectiveness. After height adjustment, the sign 3 with the desired display content is horizontally inserted into the mounting groove 10 on one side of the mounting frame 2. The size of the mounting groove 10 matches the shape of the sign 3, providing basic positioning support. As the sign 3 is pushed in, its two edges enter the insertion groove 8 area on both sides of the inner wall of the mounting groove 10. The insertion groove 8 is movably connected to a limit plate 9, ensuring the sign 3... Under the side compression, the limiting plate 9 undergoes elastic or sliding displacement. After the sign 3 is fully inserted, the limiting plate 9 is manually reset so that one side of it adheres to the side wall of the sign 3, forming a lateral clamping force to prevent it from loosening and falling off. To further enhance the fixing reliability, a positioning plate 12 is fixedly connected to one side of the limiting plate 9. The positioning plate 12 is detachably connected to the side wall of the mounting frame 2. Specifically, a positioning screw 11 is set on one side of the positioning plate 12. One end of the positioning screw 11 is threaded through the positioning plate 12 and then bolted to the threaded hole on the side wall of the mounting frame 2. Tightening the positioning screw 11 can firmly lock the positioning plate 12, thereby constraining the position of the limiting plate 9 and ensuring that it stably clamps the sign 3.In addition, for ease of operation, a handle 13 is provided on one side of the positioning plate 12. The handle 13 is fixedly connected to the side wall of the positioning plate 12 by bolts. When it is necessary to change the label content, the operator can apply pulling force by holding the handle 13 to pull the positioning plate 12 outward as a whole, causing the limiting plate 9 to disengage from the side wall of the label 3, releasing the clamping state. Then, the original label 3 can be pulled out from the mounting slot 10, a new label 3 can be inserted, and the above limiting and fixing steps can be repeated to complete the replacement. The whole process does not require special tools and is simple and efficient to operate. The label 3 itself adopts a structure with light-glowing material or covered with luminous film. After absorbing natural light or ambient light during the day, it can continue to emit light at night or in low light conditions, improving visibility and warning effect in low-light environments and ensuring the safety of power operations.
[0033] This technical solution utilizes a vertical lifting structure between the base 1 and the mounting frame 2, combined with the coordinated action of the push cylinder 6, lifting cylinder 4, lifting rod, top plate 5, and bottom plate 7, to achieve automatic height adjustment of the mounting frame 2 and the sign 3. This overcomes the problem of traditional fixed signs being unable to adapt to complex terrain and viewing angles, significantly improving the readability of warning information, especially in scenarios involving slopes, uneven ground, or requiring long-distance visibility. The introduction of the push cylinder 6 makes the lifting process more labor-saving and precise, reducing the labor intensity of manual adjustment and improving response speed and ease of operation. The structural design of the mounting slot 10 and the insertion slot 8, along with the limiting plate 9 and the positioning plate 12, makes the installation and replacement of the sign 3 extremely convenient. The limiting plate 9 provides initial clamping force, and secondary locking is achieved through the detachable connection between the positioning plate 12 and the side wall of the mounting frame 2. The threaded connection of the positioning screw 11 enhances the stability and vibration resistance of the connection, ensuring the sign's stability. The sign 3 is not easily loosened in outdoor windy or vibrating environments; the handle 13 greatly improves the ease of operation of the positioning plate 12, especially when wearing gloves or in harsh environments, the disassembly can be easily completed through the handle 13, avoiding the inconvenience of direct finger operation; the movable wheel 14 detachably connected to one side of the base 1 and the pull handle 15 fixedly connected to the other side together form a convenient mobility system, enabling the entire device to be quickly moved between different work points, improving on-site management efficiency, while the detachable feature of the movable wheel 14 ensures the stability of the base 1 when in fixed use, preventing accidental slippage; the pull handle 15 is made of metal to ensure structural durability, while the outer rubber sleeve improves the safety and comfort of gripping, taking into account both strength and ergonomic requirements; the sign 3 uses self-illuminating material, enabling continuous illumination at night without external power supply, solving the problem of poor nighttime visibility of traditional signs, and enhancing all-weather warning capability.
