Description

Technical Field

[0001] This invention relates to the field of warning sign technology, and specifically to a warning sign for construction projects. Background Technology

[0002] Warning signs are standard emergency equipment on vehicles, typically triangular in shape, hence the name "triangular warning sign." The reflective portion of the warning sign utilizes the retroreflective principle of high-refractive-index glass microspheres and the micro-rhomboid reflective principle of reflective lattices, manufactured through advanced focusing and post-processing techniques. It reflects direct light from a distance back to the light source, providing excellent retroreflective optical performance both day and night. Especially at night, it offers visibility comparable to daytime. Warning signs made with this high-visibility reflective material are easily spotted by nighttime drivers, whether the user is at a distance or under conditions of direct or diffused light interference.

[0003] Construction safety warning signs are commonly used in engineering construction to remind workers to pay attention to construction safety. However, due to the large amount of dust generated on construction sites, the warning words on the safety signs are easily covered by dust, making it difficult for workers to see the warning content. Therefore, regular cleaning of the warning signs is necessary, and the current cleaning method is generally manual cleaning. At the same time, for the convenience of construction, the warning signs are generally not placed in a fixed location on the construction site, so they are easily blown down when it is windy.

[0004] Therefore, there is a need to design a warning sign for construction projects that is easy to clean and has good stability. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a warning sign for construction projects, comprising a frame, a clamping warning plate, a cleaning component, and an extension component. The warning plate is slidably mounted on the frame, and clamping components are provided on both sides of the frame to hold the warning plate. A cleaning component is provided on the frame for cleaning the warning plate. When the warning plate rises, the cleaning component in the cleaning component contacts the warning plate to clean it. An extension component is provided on the frame to improve the stability of the frame. After the extension component is extended, it increases the contact area with the ground and forms a triangular structure with the frame.

[0006] Preferably, the cleaning assembly includes a mounting frame, wedge blocks, a cleaning block, a support rod, a spring, and a pressing plate. The mounting frame is slidably mounted on the inner walls of the upper part of the frame along the two length directions via the support rod. The spring is positioned between the mounting frame and the inner wall of the frame. The cleaning block is movably mounted on the inner side of the mounting frame. A limiting component for limiting the cleaning block is slidably mounted on the top of the mounting frame. The wedge blocks are positioned on both sides of the top width direction of the mounting frame. Two adjacent pressing plates are positioned on the two longitudinal side walls of the warning plate. When the warning plate rises, the pressing plates move upward to press the wedge blocks. The wedge blocks drive the mounting frame and the cleaning block to move closer to the warning plate. The cleaning block contacts and engages with the longitudinal surface of the warning plate.

[0007] Preferably, the expansion assembly includes a guide rod, a sliding rod, an expansion block, a guide block, and a sliding block. The sliding blocks are slidably disposed on both the front and back side walls of the frame. The guide rods are disposed on both sides of the frame with respect to the vertical plate, and are parallel to the vertical plate. The guide rods slide through the sliding blocks. The sliding rods are rotatably mounted on the sliding blocks. The end of the sliding rod away from the sliding block is connected to the expansion block. The guide block for guiding the sliding rods is disposed on the lower side wall of the frame facing away from the warning plate.

[0008] Preferably, the limiting component includes an L-bar, a second spring, and a limiting block. The L-bar is slidably disposed on both sides of the top width direction of the mounting bracket. The limiting block is connected to one end of the L-bar facing the cleaning block. The second spring is disposed between the connection point of the L-bar and the mounting bracket and the limiting block. In the initial state, the limiting block is located above the cleaning block.

[0009] Preferably, it further includes a push rod and a triangular block. The push rod is slidably disposed on the two outer walls of the upper part of the frame along its length. The two ends of the push rod are connected to the triangular block. The triangular block is pressed against the end of the L rod away from the limiting block.

[0010] Preferably, the triangular block is a right triangle, and one side of the inclined surface of the triangular block is pressed into the L-bar.

[0011] Preferably, it further includes a connecting block, a pull rope, and a pulley. The sliding block is connected to the connecting block perpendicular to the vertical plate of the frame on the side facing the warning plate. The pull rope is connected to the connecting block. The pulley is provided on the lower part of the vertical plate of the frame on the side facing the warning plate. The end of the pull rope away from the connecting block passes around the pulley and is connected to the side wall of the warning plate.

[0012] Preferably, it also includes a connecting rod and a spring five, with the connecting rod being connected to the side of two adjacent sliding blocks facing away from the warning plate, and the spring five being disposed between the connecting rod and the lower part of the frame.

[0013] Preferably, the device further includes reflective warning components on both outer walls of the frame facing away from the warning plate. The reflective warning components include a motor mounted on the outer wall of the frame, a side frame connected to the outer wall of the frame, a rotating shaft mounted on the upper and lower parts of the side frame, and a reflective strip between the rotating shafts. The output shaft of the motor is connected to a rotating shaft.

[0014] Preferably, the warning board also includes telescopic baffles on both sides of its top.

[0015] The beneficial effects of the present invention are as follows: 1. The rising of the warning plate drives the extrusion plate to rise synchronously. When the extrusion plate rises, it exerts an extrusion force on the wedge block. The wedge block is pressed and drives the mounting frame and the cleaning block to move towards the warning plate. This allows the cleaning block to contact and cooperate with the surface of the warning plate. When the warning plate moves up, the cleaning block scrapes off the dust on its surface, thereby realizing the function of convenient cleaning of the warning plate.

[0016] 2. At the same time, when the warning board rises, the sliding block moves downward through the pull rope. The sliding block moves downward, causing the sliding rod to move downward along the guide block. This places the extension block on the placement plane, forming a triangular structure with the sliding rod, the frame, and the placement plane, thus improving the stability of the device.

[0017] 3. The push rod drives the triangular block to move towards the L-bar, and the triangular block squeezes the L-bar at an angle, causing the L-bar to move the limit block away from the cleaning block, thus enabling convenient replacement of the cleaning block. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] Example: A warning sign for construction projects, such as Figure 1 and Figure 2 As shown, the device includes a frame 1, clamping components 2, a spring 201, a warning plate 3, a cleaning assembly, and an extension assembly. The upper part of the frame 1 is rectangular, and the warning plate 3 is slidably mounted on the frame 1, passing through the rectangle at the top of the frame 1. Clamping components 2 are provided on both sides of the frame 1 to clamp the warning plate 3. The clamping components 2 include an n-shaped rod and clamping blocks connected to both ends of the n-shaped rod. A spring 201 is provided between the clamping block in contact with the warning plate 3 and the frame 1. The spring 201 is wound around the n-shaped rod and is a compression spring. Figure 2The image shows its compressed state. The frame 1 is equipped with a cleaning component for cleaning the warning plate 3. When the warning plate 3 rises, the cleaning component in the cleaning component contacts the warning plate 3 to clean it. The frame 1 is equipped with an extension component to improve the stability of the frame 1. After the extension component is unfolded, it increases the contact area with the ground and forms a triangular structure with the frame 1.

[0032] like Figure 3 and Figure 4 As shown, the cleaning assembly includes a mounting frame 4, a wedge block 5, a cleaning block 6, a support rod 9, a spring 901, and a pressing plate 10. The mounting frame 4 is slidably mounted on the inner walls of the upper part of the frame 1 along its two length directions via the support rod 9. The mounting frame 4 is horizontally placed in an n-shape, and a long strip plate is installed inside the mounting frame 4. A spring 901 is installed between the mounting frame 4 and the inner wall of the frame 1, and the spring 901 is wound around the support rod 9. The initial state of the spring 901 is as follows... Figure 4 As shown, spring 3 901 is a tension spring. A cleaning block 6 is detachably mounted inside the mounting bracket 4. The cleaning block 6 is mounted on a long plate inside the mounting bracket 4. A limiting component is slidably mounted on the top of the mounting bracket 4 to limit the movement of the cleaning block 6. Figure 4 As shown, the limiting assembly includes an L-bar 7, a second spring 701, and a limiting block 8. The L-bar 7 is slidably mounted on both sides of the top width direction of the mounting frame 4. The end of the L-bar 7 facing the cleaning block 6 is connected to the limiting block 8, and the end of the L-bar 7 away from the limiting block 8 is slidably engaged with the top of the frame 1. A second spring 701 is positioned between the connection point of the L-bar 7 and the mounting frame 4 and the limiting block 8. The initial state of the second spring 701 is as follows... Figure 4 As shown, with the setting of spring 701, in the initial state, the limiting block 8 is located above the cleaning block 6. Wedge blocks 5 are set on both sides of the top width direction of the mounting bracket 4. Two adjacent extrusion plates 10 are set on the two longitudinal side walls of the warning plate 3. The top of the extrusion plate 10 is set with an inclined surface. When the warning plate 3 rises, the extrusion plate 10 moves upward to extrude the wedge blocks 5. The wedge blocks 5 drive the mounting bracket 4 and the cleaning block 6 to move closer to the warning plate 3. The cleaning block 6 contacts and cooperates with the longitudinal surface of the warning plate 3.

[0033] like Figure 5 and Figure 6 As shown, the expansion assembly includes a guide rod 11, a sliding rod 12, an expansion block 121, a guide block 13, a sliding block 14, and a spring 141. Semi-circular sliding blocks 14 are slidably mounted on both the front and back side walls of the frame 1. Guide rods 11, parallel to the vertical plate, are arranged on both sides of the frame 1, centered on the vertical plate. The guide rods 11 slide through the sliding blocks 14. A sliding rod 12 is rotatably mounted on the sliding block 14. A spring 141, a torsion spring, is positioned between the sliding block 14 and the sliding rod 12. Its initial state is as follows: Figure 6As shown, the end of the sliding rod 12 away from the sliding block 14 is connected to an extension block 121. Slide grooves are provided on the opposing sides of two adjacent sliding rods 12. A guide block 13 is provided on the side wall of the lower part of the frame 1 facing away from the warning plate 3 to guide the sliding rod 12. The end of the guide block 13 away from the frame 1 is slidably disposed in the slide groove of the sliding rod 12.

[0034] like Figure 9 As shown, it also includes a connecting block 17, a pull rope 18, a pulley 19, a connecting rod 20, and a spring 21. The side of the sliding block 14 facing the warning plate 3 is connected to the connecting block 17, which is perpendicular to the vertical plate of the frame 1. A pull rope 18 is connected to the connecting block 17. A pulley 19 is located on the lower part of the vertical plate of the frame 1 facing the warning plate 3. The end of the pull rope 18 away from the connecting block 17 passes around the pulley 19 and connects to the side wall of the warning plate 3. Adjacent sliding blocks 14 on the side facing away from the warning plate 3 are connected to the connecting rod 20. When the sliding rod 12 slides to the lower part of the frame 1, the adjacent two sliding blocks 14 are fixed by the connecting rod 20. A spring 21 is located between the connecting rod 20 and the lower part of the frame 1. Figure 9 The diagram shown is of the state of spring 521 after stretching and deformation.

[0035] In use, by lifting the warning plate 3 upwards, the warning plate 3 drives the pressing plate 10 to move upwards simultaneously. After the pressing plate 10 contacts the wedge block 5, it presses the wedge block 5. The wedge blocks 5 on both sides move towards each other due to the pressure, thereby driving the mounting frame 4 and the cleaning block 6 on the mounting frame 4 to move towards the warning plate 3. The cleaning block 6 contacts the surface of the warning plate 3. When the warning plate 3 moves upwards, the cleaning block 6 scrapes off the dust on the surface of the warning plate 3, thereby achieving the function of efficiently cleaning the warning plate 3. At the same time, when the warning plate 3 moves upwards, it drives the pull rope 18 connected to it to move upwards. When the pull rope 18 is pulled upwards, it drives the sliding block 14 to move downwards along the vertical plate of the frame 1 through the connecting block 17. When the sliding block 14 slides downwards... The sliding block 14 drives the sliding rod 12 to move downward. When the sliding rod 12 moves downward, it rotates around the connection point with the sliding block 14. The spring 141 deforms, and the guide block 13 provides guidance for the movement of the sliding rod 12. When the sliding block 14 moves downward to the lower part of the vertical plate of the frame 1, it contacts the ground through the extension block 121, so that the sliding rod 12, the frame 1, and the ground form a triangular structure, thereby improving the stability of the device. In this way, the warning plate 3 is moved upward to the top of the frame 1 and clamped and fixed by the clamping member 2. The warning plate 3 provides a safety warning to the construction personnel. At the same time, the sliding rod 12 and the extension block 121 increase the contact area between the device and the ground, improving the stability of the device during use.

[0036] When the device needs to be retracted, pull the clamping member 2 away from the warning plate 3 to release the clamping member 2 from the warning plate 3. The warning plate 3 moves down to reset. Under the action of the elastic force of the spring 141, the spring 141 drives the sliding block 14 and the sliding rod 12 to slide upward to reset.

[0037] like Figure 7 and Figure 8 As shown, it also includes a push rod 15 and a triangular block 16. The push rod 15 is slidably arranged on the two outer walls of the upper part of the frame 1 along the length direction. The two ends of the push rod 15 are connected to the triangular block 16. The triangular block 16 is a right triangle. The triangular block 16 is pressed and engaged with the end of the L rod 7 away from the limit block 8. The inclined side of the triangular block 16 is pressed and engaged with the L rod 7.

[0038] The push rod 15 drives the triangular block 16 to move towards the warning plate 3. The triangular block 16 presses the L rod 7 at an angle. The L rod 7, when pressed, drives the limiting block 8 to move away from the cleaning block 6, thereby releasing the limitation on the cleaning block 6. At this time, the cleaning block 6 can be easily removed from the mounting bracket 4, realizing the function of easily replacing the cleaning block 6.

[0039] like Figure 10 As shown, the frame 1 also includes reflective warning components installed on both outer walls facing away from the warning panel 3. The reflective warning components include a motor 22 installed on the outer wall of the frame 1, a side frame 23 connected to the outer wall of the frame 1, a rotating shaft installed on the upper and lower parts of the side frame 23, and a reflective strip 24 between the rotating shaft. The output shaft of the motor 22 is connected to a rotating shaft, and the rotating shaft is driven to rotate by the motor 22. The rotating shaft drives the reflective strip 24 to rotate, making the red and yellow reflective strips on the reflective strip 24 more conspicuous and avoiding visual fatigue.

[0040] like Figure 11 As shown, the warning board 3 also includes telescopic baffles 25 on both sides of the top. When the telescopic baffles 25 are unfolded, they can provide rain protection for the warning board 3.

[0041] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
