Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of engineering signage, and more specifically, to an easily adjustable municipal engineering signage. Background Technology

[0002] In municipal engineering construction and management, signs serve as crucial facilities for guiding roads and warning of dangers. Their mobility and height adjustability directly impact construction efficiency and safety protection effectiveness. However, traditional municipal engineering signs generally suffer from significant drawbacks in practical applications, such as difficulty in movement and inconvenience in height adjustment, making them unsuitable for the dynamic needs of construction sites.

[0003] Most existing signs use concrete bases or bolt-fixed structures, with each sign typically weighing tens of kilograms. Moving them requires tools such as crowbars or forklifts to break the foundation, which is not only time-consuming and labor-intensive but also prone to causing ground damage. For example, this severely restricts construction progress during road construction area adjustments or temporary traffic control scenarios. Furthermore, while some signs use metal bracket structures, height adjustment relies on segmented sleeves and bolts. Operators must carry wrenches and other tools to adjust each segment individually, and loose bolts can cause the sign to tilt, posing a safety hazard.

[0004] Furthermore, traditional signs have a limited height adjustment range, making them unsuitable for different road conditions (such as overpasses and tunnel entrances) where visibility needs vary. When construction areas have slopes or obstacles, fixed-height signs often lose their warning function due to obstructed views. In municipal engineering projects, frequent changes in construction phases within the project cycle necessitate multiple moves and height adjustments for signs. Traditional methods not only increase maintenance costs but may also lead to a higher rate of sign damage due to cumbersome operations.

[0005] With the advancement of smart city and efficient construction concepts, municipal engineering projects are placing higher demands on the portability and adaptability of signage. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide an easily adjustable municipal engineering sign, which solves the technical problems of the existing technology that the overall size is heavy and inconvenient to move and the height is inconvenient to adjust.

[0007] According to one aspect, at least one embodiment of this disclosure provides an easily adjustable municipal engineering sign, comprising:

[0008] The system comprises a base frame, several uprights, and a pair of sign bodies. The uprights are fixed at the four opposite corners of the base frame surface, and the sign bodies are mounted on the top of the uprights.

[0009] A pair of connecting rods and a height adjustment assembly, wherein the connecting rods are disposed on the column and the height adjustment assembly is disposed between the connecting rods and the column;

[0010] A movable component, the movable component being mounted on the base frame;

[0011] A connecting component is disposed between the sign body and the connecting rod;

[0012] The height adjustment assembly includes a pair of support rods, which are fixed at both ends of the bottom of the connecting rod. The lower end of the support rod is movably fitted inside the column. The side surface of the column is provided with protrusions. Both ends of the bottom of the connecting rod are provided with first screws, which are movably fitted inside the protrusions. A pair of nuts are screwed onto the first screws, which are located at the upper and lower ends of the protrusions.

[0013] As a further technical solution, the connecting assembly includes several splicing rods, which are rotatably connected to the four opposite corners of the main surface of the signboard via pins. The pair of splicing rods at the top and the pair of splicing rods at the bottom rotate in opposite directions.

[0014] As a further technical solution, the main body of the sign is rotatably connected to one end of the connecting rod by a pin, and a pair of opposite splicing rods are spliced ​​together, with tension bolts screwed between the splicing rods.

[0015] As a further technical solution, the mobile component includes a pair of outer frames, which are fixed to the side faces of the pair of columns. A second screw is connected to the inner side of the outer frame by a threaded connection. The lower end of the second screw is rotatably connected to a base plate, and a pair of moving wheels are provided at the bottom of the base plate.

[0016] As a further technical solution, a round rod is provided on the surface of the base plate, the round rod is movably fitted into the outer frame, a connecting plate is fixedly connected to the upper end of the round rod, the upper end of the second screw is rotatably fitted into the connecting plate, and a screwing block is provided at the upper end of the second screw.

[0017] As a further technical solution, the splicing joint of the splicing rod has a stepped structure.

[0018] As a further technical solution, the main body of the sign is provided with several locking blocks, and the splicing rod has a locking groove on its surface.

[0019] As a further technical solution, the main surface of the signboard is provided with several ventilation holes.

[0020] As a further technical solution, the main body of the sign can be rotated 180° through the connection point with the connecting rod pin.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. In this disclosure, the height adjustment component allows the connecting rod to move up and down along the column through the sliding fit between the support rod and the column. The height of the sign body can be adjusted by loosening or tightening the nut. Stepless adjustment can be achieved without tools, which solves the problem of fixed or cumbersome adjustment of traditional sign heights. It adapts to different road conditions and sight requirements. The clamping structure of the protrusion and nut ensures that the sign is stable and does not wobble after adjustment. The support rod inserted into the column plays a guiding role to prevent the sign from tilting during adjustment, thus improving the flexibility and reliability of sign installation in municipal engineering.

[0023] 2. In this disclosure, the moving component drives the second screw to rotate via a screwing block, causing the base plate to lift and lower the moving wheels. When rotating clockwise, the moving wheels contact the ground and lift the signboard, allowing it to be moved. When rotating counterclockwise, the moving wheels lift off the ground, and the signboard is stably supported on the ground. Switching between moving and fixed states can be achieved without the need for external force, solving the problem of traditional signboards being difficult to move and requiring tools. The sliding cooperation between the round rod and the outer frame ensures smooth lifting and lowering of the base plate, and the connecting plate restricts the axial displacement of the screw, making the moving process safe and reliable. This is suitable for scenarios where construction areas are frequently adjusted in municipal engineering projects.

[0024] 3. In this disclosure, the connecting component is connected to the main body of the signboard via a splicing rod. The top and bottom splicing rods rotate in opposite directions, allowing adjacent signboard bodies to be spliced ​​into a whole. Tightening the bolts fixes the splicing joint, enhancing the connection strength. When storage is required, the bolts are loosened, and the splicing rod flips, causing the main body of the signboard to fold, reducing the transportation volume. This solves the problem of traditional signs being unable to be assembled or inconvenient to store. The stepped splicing joint enhances the connection stability, and the protrusions and slots work together to fix the splicing rod after folding. The ventilation holes reduce the wind resistance of the signboard, adapting to the usage needs of different construction scenarios and improving the practicality and portability of municipal engineering signs.

[0031] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0032] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0033] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0034] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-4 As shown, it illustrates an adjustable municipal engineering sign according to an embodiment of the present disclosure, comprising:

[0038] The base frame 1, several uprights 2 and a pair of sign bodies 3 are provided. The uprights 2 are fixed at the four opposite corners of the surface of the base frame 1, and the sign bodies 3 are set on the top of the uprights 2.

[0039] A pair of connecting rods 4 and a height adjustment component 5, wherein the connecting rods 4 are disposed on the column 2 and the height adjustment component 5 is disposed between the connecting rods 4 and the column 2;

[0040] Movable component 7, which is mounted on the base frame 1;

[0041] Connection component 6, which is disposed between the sign body 3 and the connecting rod 4;

[0042] The height adjustment assembly 5 includes a pair of support rods 5-1, which are fixed at both ends of the bottom of the connecting rod 4. The lower end of the support rod 5-1 is movably fitted inside the column 2. The side surface of the column 2 is provided with a protrusion 5-2. Both ends of the bottom of the connecting rod 4 are provided with a first screw 5-3, which is movably fitted inside the protrusion 5-2. A pair of nuts 5-4 are screwed onto the first screw 5-3, and the nuts 5-4 are located at the upper and lower ends of the protrusion 5-2.

[0043] In some examples, to adapt to the height requirements of different installation scenarios, a height adjustment component 5 is designed. This component uses support rods 5-1 fixed at both ends of the bottom of the connecting rod 4 as a guide structure. The lower end of the support rod 5-1 is movably fitted inside the column 2 and can slide up and down along the axis of the column 2. The protrusions 5-2 on the side surface of the column 2 serve as adjustment and positioning structures. The first screw 5-3 passing through it is fixed at both ends to the bottom of the connecting rod 4. A pair of nuts 5-4 on the screw clamp the two sides of the protrusions 5-2 to lock the height of the connecting rod 4. When the height needs to be adjusted, the upper and lower nuts 5-4 are loosened, pushing the connecting rod 4 to slide along the support rod 5-1 to the target position. Then, the nuts 5-4 are tightened to fix it, so that the main body of the sign 3 rises and falls synchronously with the connecting rod 4. Through the sliding cooperation between the support rod 5-1 and the column 2, and the clamping and positioning of the protrusions 5-2 and the nuts 5-4, the height adjustment component 5 realizes stepless adjustment of the height of the main body of the sign 3, which can meet the installation requirements under different line of sight or terrain conditions, and has both convenient adjustment and structural stability.

[0044] like Figures 1-4 As shown in the figure, this embodiment proposes that the connecting component 6 includes a plurality of splicing rods 6-1. The splicing rods 6-1 are rotatably connected to the four opposite corners of the surface of the sign body 3 by pins. The pair of splicing rods 6-1 located at the top and the pair of splicing rods 6-1 located at the bottom rotate in opposite directions. The sign body 3 is rotatably connected to one end of the connecting rod 4 by pins. The pair of opposite splicing rods 6-1 are spliced ​​together, and tension bolts 6-2 are screwed between the splicing rods 6-1.

[0045] In some examples, a connecting component 6 is designed to enable the combined use and convenient storage of multiple sign bodies 3. This component uses the splicing rods 6-1 at the four corners of the sign body 3 as connecting units, which are rotatably connected to the body via pins. The top and bottom splicing rods 6-1 are designed to rotate in opposite directions (top rotates downwards, bottom rotates upwards), allowing adjacent sign bodies 3 to be joined together via the splicing rods 6-1. When joined, the opposite splicing rods 6-1 are fixed by tightening bolts 6-2 to form a rigid connection structure. When it needs to be folded up, the bolts are loosened, and the top and bottom splicing rods 6-1 flip in opposite directions, causing the sign body 3 to fold downwards and fit against the side of the connecting rod 4, reducing the transportation volume.

[0046] This flip-and-assemble design not only meets the need for displaying multiple signs side by side, but also allows for compact storage when not in use, making it suitable for flexible arrangement and quick disassembly in temporary construction areas.

[0047] like Figures 1-4As shown in the figure, the mobile component 7 in this embodiment includes a pair of outer frames 7-1. The outer frames 7-1 are fixed to the side end faces of a pair of columns 2. A second screw 7-2 is threadedly connected inside the outer frame 7-1. A base plate 7-3 is rotatably connected to the lower end of the second screw 7-2. A pair of moving wheels 7-4 are provided at the bottom of the base plate 7-3. A round rod 7-5 is provided on the surface of the base plate 7-3. The round rod 7-5 is movably fitted inside the outer frame 7-1. A connecting plate 7-6 is fixedly connected to the upper end of the round rod 7-5. The upper end of the second screw 7-2 is rotatably fitted inside the connecting plate 7-6. A screwing block 7-7 is provided at the upper end of the second screw 7-2.

[0048] In some examples, a moving component 7 is designed to facilitate convenient movement and stable support of the signboard. This component uses an outer frame 7-1 fixed to the side end of the column 2 as its support base. The internal second screw 7-2 is threaded into the outer frame 7-1. The lower end of the base plate 7-3, which is rotatably connected, integrates a pair of moving wheels 7-4. The screw can be manually rotated by a screw block 7-7 at the upper end of the screw: when the screw block 7-7 is rotated clockwise, the screw causes the base plate 7-3 to descend, the moving wheels 7-4 contact the ground, and the entire signboard is lifted and can be moved; when rotated counterclockwise, the base plate 7-3 rises, the moving wheels 7-4 leave the ground, and the sliding engagement between the round rod 7-5 and the outer frame 7-1 ensures that the base plate 7-3 rises and falls smoothly. The connecting plate 7-6 restricts the axial displacement of the screw and improves structural stability.

[0049] Through the lifting control of the screw drive, the moving component 7 realizes the rapid switching between the "moving state" and "fixed state" of the sign, without the need for additional lifting equipment, which facilitates the position adjustment and fixation on the construction site, and takes into account both mobility and support reliability.

[0050] For example, such as Figure 1 As shown, the splicing joint of the splicing rod 6-1 has a stepped structure.

[0051] In some examples, a stepped design can be used to strengthen the connection between the two splicing rods 6-1.

[0052] For example, such as Figure 2 As shown, the main body 3 of the signboard is provided with several card blocks 8, and the splicing rod 6-1 has a card slot 9 on its surface.

[0053] In some examples, the splicing rod 6-1 can be fixed by inserting the locking block 8 into the locking slot 9 when it is rotated 90° to retract.

[0054] For example, such as Figure 1 As shown, the main body 3 of the sign has several ventilation holes 10 on its surface.

[0055] In some examples, the ventilation holes 10 can provide wind protection and help cope with strong winds.

[0056] For example, such as Figure 1 As shown, the sign body 3 can be rotated 180° through the pin connection with the connecting rod 4.

[0057] In some examples, the sign body 3 can be rotated by 180°.

[0058] In actual use: Place the base frame 1 in the designated position, fix the columns 2 at the four opposite corners of the base frame 1, connect the main body 3 of the sign to one end of the connecting rod 4 via a pin, connect the connecting rod 4 to the column 2 via the height adjustment component 5, insert the lower end of the support rod 5-1 into the column 2, pass the first screw 5-3 through the protrusion 5-2, screw the nut 5-4 onto the screw to clamp the protrusion 5-2, fix the outer frame 7-1 of the moving component 7 to the side of the column 2, screw the second screw 7-2 into the outer frame 7-1, and rotatably connect the base plate 7-3 to the lower end of the screw. The driving wheel 7-4 is installed at the bottom of the base plate 7-3. The round rod 7-5 passes through the outer frame 7-1 and is fixed to the connecting plate 7-6. The screw block 7-7 is installed at the upper end of the screw. The splicing rod 6-1 of the connecting component 6 is connected to the four corners of the sign body 3 by the pin. The top and bottom splicing rods 6-1 rotate in opposite directions. Adjacent sign bodies 3 are spliced ​​by the splicing rods 6-1 and fixed with the tension bolts 6-2. The sign body 3 can rotate 180° around the pin. The ventilation hole 10 is opened on the surface of the sign. The locking block 8 is fixed in place with the locking groove 9 of the splicing rod 6-1.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
