Description

Technical Field

[0001] This utility model relates to the field of power construction technology, specifically a portable power construction sign. Background Technology

[0002] Power construction refers to a series of construction activities carried out in power engineering projects, mainly including power source construction and power grid construction. Power source construction involves the construction of power plants, including traditional power construction and new energy power construction, such as thermal power, hydropower, wind power, nuclear power, and biomass power. Power grid construction mainly involves the construction of transmission lines. During power construction, it is necessary to provide warnings at the construction site. Traditionally, warning methods involve placing signs at the construction site, but traditional signs are bulky and inconvenient to carry. To improve this situation, a portable power construction sign is proposed.

[0003] For example, a portable power construction sign disclosed in the authorization announcement number CN217086084U includes a fixing device, a connecting device, and a sign. The fixing device includes a first fixing base and a second fixing base. The connecting device is connected between the first fixing base and the second fixing base. The sign is detachably connected to the top of the second fixing base. The sign includes four sign plates. The four sign plates are connected end to end to form a bottomless cube. Adjacent sign plates are rotatably connected. Reflective marking blocks are provided on the outer side of the sign plates.

[0004] Although it achieves the fixing and support of the signboard through the first and second fixing seats, the connecting device and the signboard can be easily disassembled. It is convenient to assemble and disassemble during use, which can save a lot of equipment installation time, and is easy to store and transport.

[0005] However, this does not solve the problem that existing construction signs are not convenient for modular assembly and disassembly, nor for flexible adjustment of warning height and content, thus affecting portability. Utility Model Content

[0006] The purpose of this utility model is to provide a portable power construction sign to solve the problems mentioned in the background art, such as the inconvenience of modular assembly and disassembly of construction signs, the difficulty in flexibly adjusting the warning height and warning content, and the impact on portability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable power construction sign, comprising a support rod and support legs. Three sets of support legs are evenly spaced on the outer wall of the support rod. Each support leg has a hinge shaft at one end near the support rod, and the support leg is movably connected to the support rod via the hinge shaft. Each support leg has a linkage arm on its side wall, and each linkage arm has a linkage shaft at one end near the support leg, and the linkage arm is movably connected to the support leg via the linkage shaft. Each linkage arm also has a connecting shaft at one end near the support rod, and the linkage arm is movably connected to the support rod via the connecting shaft. A telescopic rod is slidably installed inside the support rod. A pin is provided on one side wall of the telescopic rod, extending through the support rod into the interior of the telescopic rod. A connector is installed at the top of the telescopic rod.

[0008] Preferably, a plug post is slidably installed inside the plug socket, and a connecting plate is installed at the top of the plug post.

[0009] Preferably, limit rings are symmetrically installed on the outer wall of the plug-in socket, and limit posts are slidably installed inside each limit ring.

[0010] Preferably, each of the limiting posts is provided with a first spring, and the two ends of the first spring are respectively connected to the limiting ring and the limiting post, and the limiting post can be inserted into the groove on the surface of the plug post.

[0011] Preferably, a sign body is installed at the top of the connecting plate, and rhomboid blocks are symmetrically arranged inside the sign body.

[0012] Preferably, the rhombus block is provided with movable shafts at both the upper and lower ends, and the rhombus block is movably connected to the sign body through the movable shafts.

[0013] Preferably, a support frame is symmetrically installed on the side wall of the sign body, and a pull-out column is slidably installed inside the support frame, and the pull-out column passes through the sign body and can be inserted into the interior of the movable shaft.

[0014] Preferably, each of the pull-out columns is provided with a second spring, and the two ends of the second spring are respectively connected to the pull-out column and the support frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the construction sign not only realizes convenient modular assembly and disassembly, which facilitates flexible adjustment of the warning height and warning content, but also improves the portability;

[0016] The device is transported to the power construction site. The support legs are rotated, and the support legs rotate around the hinge shaft. The support legs, through the linkage shaft, drive the linkage arm to rotate around the connecting shaft, thus unfolding the three sets of support legs. The support legs provide stable support for the support rod. The pin is pulled out, and the telescopic rod is moved upwards to adjust its height. After adjusting to the usable height, the pin is reinserted to securely connect the telescopic rod and the support rod. Then, the sign body is removed, and the sign body moves the connecting plate and the plug-in post. The plug-in post is inserted into the plug-in seat, pressing against the limiting post and causing it to move outwards within the limiting ring. The limiting post presses against the first spring. When the groove on the surface of the plug-in post moves to the position of the limiting post, the first spring causes the limiting post to reset and insert into the groove on the surface of the plug-in post, thus securing the plug-in post to the plug-in seat. The sign body is then installed on the telescopic rod, and the construction status label is displayed accordingly. The sign is first attached to the surface of the diamond-shaped block. Pulling the pull-out column, with the support frame's limiting action, causes the pull-out column to compress the second spring, pulling it out from inside the movable shaft. Then, rotating the diamond-shaped block aligns the current construction process with the display direction, facilitating view for passersby and serving as a warning. Releasing the pull-out column allows the second spring to reset it and insert it back into the movable shaft, securing the diamond-shaped block to the sign body. When it needs to be carried, pulling the limiting column outward disengages the insertion post from the insertion seat, allowing the sign body to be removed. Rotating the linkage arm causes the support leg to fold and rotate via the linkage shaft. Pulling out the movable shaft retracts the telescopic rod into the support rod, reducing space occupation and facilitating carrying. This modular design allows for convenient assembly and disassembly, facilitating flexible adjustment of warning height and content, and improving portability. Attached Figure Description

Each linkage arm 10 is provided with a connecting shaft 11 at one end near the support rod 1, and the linkage arm 10 is movably connected to the support rod 1 through the connecting shaft 11. A telescopic rod 2 is slidably installed inside the support rod 1. A pin 6 is provided on the side wall of the support rod 1 on one side of the telescopic rod 2, and the pin 6 extends through the support rod 1 into the interior of the telescopic rod 2. A plug seat 5 is installed at the top of the telescopic rod 2.

[0025] A plug-in post 13 is slidably installed inside the plug-in socket 5. A connecting plate 4 is installed on the top of the plug-in post 13. Limiting rings 14 are symmetrically installed on the outer wall of the plug-in socket 5. Limiting posts 15 are slidably installed inside each of the limiting rings 14.

[0026] Each of the limiting posts 15 is provided with a first spring 12, and the two ends of the first spring 12 are respectively connected to the limiting ring 14 and the limiting post 15, and the limiting post 15 can be inserted into the groove on the surface of the plug post 13.

[0027] The top of the connecting plate 4 is equipped with a sign body 3. The sign body 3 is symmetrically arranged with rhomboid blocks 17 inside. Both the upper and lower ends of the rhomboid blocks 17 are provided with movable shafts 16, and the rhomboid blocks 17 are movably connected to the sign body 3 through the movable shafts 16.

[0028] A support frame 20 is symmetrically installed on the side wall of the sign body 3. A pull-out column 18 is slidably installed inside the support frame 20, and the pull-out column 18 passes through the sign body 3 and can be inserted into the interior of the movable shaft 16.

[0029] Each of the pull-out columns 18 is provided with a second spring 19, and the two ends of the second spring 19 are respectively connected to the pull-out column 18 and the support frame 20;

[0030] When electrical construction is required, the device is transported to the construction site. The support legs 8 are rotated, and the support legs 8 rotate around the hinge shaft 7. The support legs 8, through the linkage shaft 9, drive the linkage arm 10 to rotate around the connecting shaft 11, thus unfolding the three sets of support legs 8. The support legs 8 provide stable support for the support rod 1. The pin 6 is then pulled out, and the telescopic rod 2 is moved upwards to adjust its height. After adjusting to the usable height, the pin 6 is reinserted to securely connect the telescopic rod 2 and the support rod 1. Then, the sign body 3 is removed, and the sign body 3 drives the linkage arm 10 to rotate. The connecting plate 4 and the plug-in post 13 move, inserting the plug-in post 13 into the plug-in seat 5. The plug-in post 13 presses against the limiting post 15, causing the limiting post 15 to move outward inside the limiting ring 14. The limiting post 15 presses against the first spring 12. When the groove on the surface of the plug-in post 13 moves to the position of the limiting post 15, under the elastic cooperation of the first spring 12, the first spring 12 drives the limiting post 15 to reset and insert the limiting post 15 into the groove on the surface of the plug-in post 13, thereby fixing the plug-in post 13 to the plug-in seat 5, and thus installing the sign body 3 on the telescopic pole. 2. Place the construction progress labels sequentially on the surface of the diamond block 17. Pull out the pull-out column 18. Under the limiting action of the support frame 20, the pull-out column 18 compresses the second spring 19, pulling the pull-out column 18 out of the movable shaft 16. Then rotate the diamond block 17 to rotate the corresponding construction process to the display direction, making it convenient for passersby to view and to warn them. Release the pull-out column 18. Under the elastic action of the second spring 19, the second spring 19 drives the pull-out column 18 to reset and insert it back into the movable shaft 16, thus... The diamond-shaped block 17 is fixedly connected to the sign body 3. When it needs to be carried, the limiting post 15 is pulled outward to disengage the plug post 13 from the plug seat 5, so that the sign body 3 can be removed. The linkage arm 10 is rotated, and the linkage arm 10 drives the support leg 8 to rotate and fold through the linkage shaft 9. The movable shaft 16 is pulled out, so that the telescopic rod 2 can be retracted into the support rod 1 to reduce the space occupied and facilitate carrying. It realizes convenient modular disassembly and assembly, facilitates flexible adjustment of warning height and warning content, and improves the convenience of carrying.

[0031] Working principle: When power construction is required, the device is transported to the construction site. The support legs 8 are rotated, and the support legs 8 rotate around the hinge shaft 7. The support legs 8, through the linkage shaft 9, drive the linkage arm 10 to rotate around the connecting shaft 11, thus unfolding the three sets of support legs 8. The support legs 8 provide stable support for the support rod 1. The pin 6 is pulled out, and the telescopic rod 2 is moved upwards to adjust its height. After adjusting to the usable height, the pin 6 is reinserted to fix the telescopic rod 2 and the support rod 1. Then, the sign body 3 is removed. The sign body 3 moves the connecting plate 4 and the plug-in post 13, inserting the plug-in post 13 into the plug-in seat 5. The plug-in post 13 presses against the limiting post 15, causing the limiting post 15 to move outward within the limiting ring 14. The limiting post 15 presses against the first spring 12. When the groove on the surface of the plug-in post 13 moves to the position of the limiting post 15, under the elastic cooperation of the first spring 12, the first spring 12 drives the limiting post 15 to reset and insert it into the groove on the surface of the plug-in post 13, thus fixing the plug-in post 13 to the plug-in seat 5. Install the sign body 3 onto the telescopic pole 2, and affix the construction status labels to the surface of the rhombus block 17 in sequence. Pull the pull-out column 18, and under the limiting action of the support frame 20, the pull-out column 18 compresses the second spring 19 to pull the pull-out column 18 out of the movable shaft 16. Then rotate the rhombus block 17 to rotate the corresponding construction process to the display direction, making it convenient for passersby to view and to warn them. Release the pull-out column 18, and under the elastic action of the second spring 19, the second spring 19 drives the pull-out column 18 to return to its original position and pull out. The pull post 18 is inserted into the interior of the movable shaft 16 to fix the diamond block 17 to the sign body 3. When it needs to be carried, the limiting post 15 is pulled outward to disengage the plug post 13 from the plug seat 5, so that the sign body 3 can be removed. The linkage arm 10 is rotated, and the linkage arm 10 drives the support leg 8 to rotate and fold through the linkage shaft 9. The movable shaft 16 is pulled out, so that the telescopic rod 2 can be retracted into the support rod 1 to reduce the space occupied and facilitate carrying. The above is the complete usage of the portable power construction sign.
