Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a portable building construction warning device. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at designated locations. In construction operations, warning devices are often used and placed in designated locations to serve a certain warning function.

[0003] However, the existing warning devices have relatively simple functions. Most of them are mainly welded metal frames with an overall one-piece design. The frames are also large, making them inconvenient for users to carry and move, thus affecting their actual use. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a portable construction warning device, which solves the problem that most current warning devices are mainly welded metal frames with an overall integrated design and large frame size, which are inconvenient for users to carry and move, thus affecting actual use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable construction warning device, comprising a support frame, a connecting rod connected to the support frame, a support plate rotatably connected to the connecting rod, a connecting sleeve connected to the support plate, a cover connected to the support plate, a rotating rod rotatably connected to the support plate, a connecting plate connected to one end of the rotating rod, and a toothed ring connected to the other end of the rotating rod;

[0006] A first magnetic strip is connected to the connecting plate, a sliding groove is formed in the connecting plate, a first spring is connected in the sliding groove, a clamping plate is connected to one end of the first spring, limit blocks are connected to both sides of the clamping plate, and a writing board is installed between the two clamping plates.

[0007] As a further embodiment of this utility model: a support block is connected below the support frame and the support plate, and an anti-slip pad is connected to the support block, with anti-slip texture provided on the anti-slip pad.

[0008] As a further embodiment of this utility model: a second magnetic strip is connected to the writing board, the first magnetic strip and the second magnetic strip attract each other, and the clamp slides in the groove.

[0009] As a further embodiment of this utility model: a hollow plate is connected inside the cover, and four hollow plates are evenly distributed in a centrally symmetrical manner. A second spring is connected inside the hollow plate, and a fixing block is connected to one end of the second spring.

[0010] As a further embodiment of this utility model: limiting grooves are provided on both sides of the groove wall, the limiting block slides in the limiting groove, and the connecting sleeve is rotatably connected to the connecting rod.

[0011] As a further embodiment of this utility model: the fixing block is a triangular design, the fixing block slides inside the hollow plate, and the fixing block engages with the gear ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This portable construction warning device comprises a support frame, a support plate, a clamping plate, a first spring, a sliding groove, a first magnetic strip, a second magnetic strip, and a writing board. The writing board is pushed between the two clamping plates, causing it to push the clamping plates, which then slide within the sliding groove and stretch the first spring. The spring's elasticity pulls the clamping plate, securing it in place. Simultaneously, the first and second magnetic strips attract each other, further fixing the writing board in place. The device is simple to install and operates, improving installation efficiency. Furthermore, the device can be opened and closed by rotating the support plate and support frame, making it convenient for users to carry and use.

[0014] 2. This portable construction warning device consists of a rotating rod, a toothed ring, a hollow plate, a second spring, a fixing block, and a connecting plate. The user rotates the connecting plate, causing the rotating rod to rotate. At this time, the toothed ring pushes the fixing block through the triangular inclined surface of the fixing block, causing the fixing block to move inside the hollow plate and compress the second spring. Subsequently, the rebound of the second spring causes the fixing block to engage with the toothed ring, fixing the toothed ring and preventing accidental rotation of the rotating rod. This allows for angle adjustment between the connecting plate and the writing board to meet actual usage needs. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a portable construction warning device, including a support frame 1, a connecting rod 2 connected to the support frame 1, a support plate 3 rotatably connected to the connecting rod 2, a support block 15 connected below the support frame 1 and the support plate 3, an anti-slip pad 16 connected to the support block 15, the anti-slip pad 16 being provided with anti-slip texture, the support block 15 supports the support frame 1 and the support plate 3, and the anti-slip pad 16 can prevent the support block 15 from sliding, thereby improving the stability of the support frame 1 and the support plate 3.

[0023] A connecting sleeve 4 is connected to the support plate 3, and a cover 5 is connected to the support plate 3. Hollow plates 18 are connected inside the cover 5. There are four hollow plates 18 evenly distributed in a centrally symmetrical manner. A second spring 19 is connected inside the hollow plate 18. One end of the second spring 19 is connected to a fixing block 20. The multiple fixing blocks 20 are engaged together with the gear ring 8, thereby improving the stability of fixing the gear ring 8 and the rotating rod 6 and preventing the angle between the connecting plate 7 and the writing board 14 from rotating accidentally.

[0024] A rotating rod 6 is rotatably connected to the support plate 3. One end of the rotating rod 6 is connected to a connecting plate 7, and the other end of the rotating rod 6 is connected to a gear ring 8. The fixing block 20 is triangular in design. The fixing block 20 slides inside the hollow plate 18 and engages with the gear ring 8. Through the triangular inclined surfaces on both sides of the fixing block 20, the gear ring 8 can flexibly and quickly push the fixing block 20 to move, thereby facilitating the user to adjust the viewing angle of the writing board 14.

[0025] A first magnetic strip 9 is connected to the connecting plate 7, and a second magnetic strip 17 is connected to the writing board 14. The first magnetic strip 9 and the second magnetic strip 17 attract each other, and the clamping plate 12 slides in the slide groove 10. Through the mutual attraction between the first magnetic strip 9 and the second magnetic strip 17 and the joint clamping and fixing of multiple clamping plates 12, the writing board 14 can be fixed on the connecting plate 7 to prevent the writing board 14 from falling off when carried and moved.

[0026] A sliding groove 10 is provided in the connecting plate 7. A first spring 11 is connected in the sliding groove 10. One end of the first spring 11 is connected to a clamping plate 12. Limiting blocks 13 are connected to both sides of the clamping plate 12. A writing board 14 is installed between the two clamping plates 12. Limiting grooves 21 are provided on both sides of the sliding groove 10. The limiting blocks 13 slide in the limiting grooves 21. The connecting sleeve 4 is rotatably connected to the connecting rod 2. By sliding the limiting blocks 13 in the limiting grooves 21, the movement of the clamping plate 12 is guided and restricted by the limiting grooves 21, so as to prevent the clamping plate 12 from falling out of the sliding groove 10 when sliding.

[0027] The working principle of this utility model is as follows:

[0028] After writing the promotional information, push the writing board 14 between the two clamps 12. At this time, the writing board 14 will push the clamps 12, causing the clamps 12 to slide in the slide groove 10 and stretch the first spring 11. Thus, the clamps 12 are pulled by the elastic force of the first spring 11, so that the clamps 12 clamp and fix the writing board 14. At this time, the first magnetic strip 9 and the second magnetic strip 17 will attract each other, thus fixing the writing board 14. The installation operation is simple. Then, the warning device can be unfolded by rotating the support plate 3 and the support frame 1 and placed. The user can rotate the connecting plate 7 or the writing board 14, so that the connecting plate 7 drives the rotating rod 6 to rotate. At this time, the gear ring 8 will push the fixing block 20, causing the fixing block 20 to move into the hollow plate 18 and compress the second spring 19. Then, the rebound of the second spring 19 will make the fixing block 20 engage with the gear ring 8, fixing the gear ring 8 and preventing the rotating rod 6 from rotating accidentally. This completes the angle adjustment of the connecting plate 7 and the writing board 14 for easy viewing.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
