Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, specifically a warning sign for municipal engineering construction. Background Technology

[0002] Warning signs for municipal engineering construction are important tools for ensuring construction safety, maintaining traffic order, and protecting public interests. Their significance extends throughout the entire construction period, serving to warn passing vehicles and pedestrians. They are generally blue with white lettering, including construction icons and prompts (such as "Construction ahead, slow down").

[0003] In existing technologies, warning signs for municipal engineering construction projects often need to be portable because construction periods are finite, and therefore can be folded as needed. However, existing foldable construction warning signs cannot be folded at the sign placement position, resulting in a still relatively large overall size when folded. Therefore, an improved version of the warning sign for municipal engineering construction is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a warning sign for municipal engineering construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a warning sign for municipal engineering construction, comprising a first connecting plate, a second connecting plate disposed on one side of the first connecting plate, a first sliding groove formed on the outer surface of the first connecting plate, a second sliding groove formed on the outer surface of the second connecting plate, a first movable shaft movably engaged inside the first sliding groove, a second movable shaft movably engaged inside the second sliding groove, a first connecting rod disposed on the surfaces of both the first connecting plate and the first movable shaft, the first connecting rod being movably connected to the first connecting plate via a rotating shaft, and the first connecting rod being fixedly connected to the first movable shaft, a second connecting rod disposed on the surfaces of both the second connecting plate and the second movable shaft, the second connecting rod being movably connected to the second connecting plate via a rotating shaft, and the second connecting rod being fixedly connected to the second movable shaft, a functional compartment disposed on the outer surface of the first connecting plate, a winding roller movably disposed inside the functional compartment via a rotating shaft, a warning layer being wound on the outer surface of the winding roller, a fixing block being fixedly disposed on the outer surface of the second connecting plate, and the side of the warning layer closest to the fixing block being fixedly connected to the fixing block.

[0006] Preferably, a torsion spring is provided between the rotating shaft where the winding roller is located and the functional compartment.

[0007] Preferably, the outer surface of the warning layer is provided with reflective strips and warning slogans.

[0008] Preferably, the two first connecting rods are arranged in a cross configuration, and the two second connecting rods are arranged in a cross configuration. The first connecting rods and the second connecting rods are movably connected at the middle of their cross configuration via a pivot. The first connecting rods and the second connecting rods are also movably connected at one end close to each other via a pivot. The two first connecting rods and the two second connecting rods are movably connected to each other via pivots, so that the first connecting rods and the second connecting rods can form a scissor telescopic rod.

[0009] Preferably, both the first and second movable shafts have a first locking screw screw screwed onto their surfaces via a threaded connection.

[0010] Preferably, a fixing mechanism for fixing the angle of the support leg is provided between the support leg and the mounting shaft. The fixing mechanism includes a groove, a mounting shaft, a support leg, a rectangular block, a rectangular frame, and a spring. A groove is provided on one side of the surface of the first connecting plate and the second connecting plate. The lower end of the groove is fixedly provided with the mounting shaft. The support leg is movably provided on the surface of the mounting shaft through a bearing. A rectangular block is fixedly provided at one end of the mounting shaft. A rectangular frame is fixedly provided on the outer surface of the support leg. A spring is sleeved on the outer surface of the mounting shaft.

[0011] Preferably, the fixing mechanism further includes a second locking screw, and one end of the mounting shaft is provided with the second locking screw through a threaded connection.

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

[0013] 1. This utility model has good performance. Compared with traditional construction warning signs, the warning sign part of this device also has a folding function, which can greatly reduce the size of the entire device after folding. In this way, it is extremely convenient in the subsequent storage and transportation as the project progresses.

[0014] 2. The outriggers of this utility model are both easy and quick to deploy and fix. This device provides two methods for fixing the outriggers. The first method is locking, which uses a rectangular frame fitted onto the outer surface of a rectangular block to quickly fix the angle of the outriggers. The locking method is stable and convenient, but the structure is relatively complex. The second method is friction fixing. After the outriggers are rotated to a predetermined angle, the second locking screw is used to fix the outriggers by tightening friction. The overall structure is simple, but tightening requires tools and the fixing relies on friction. The advantages and disadvantages can be selected during production, thereby improving the applicability of this device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-8This utility model provides a technical solution: a warning sign for municipal engineering construction, including a first connecting plate 1, a second connecting plate 2 disposed on one side of the first connecting plate 1, a first sliding groove 3 formed on the outer surface of the first connecting plate 1, a second sliding groove 4 formed on the outer surface of the second connecting plate 2, a first movable shaft 5 movably engaged inside the first sliding groove 3, a second movable shaft 6 movably engaged inside the second sliding groove 4, and a first connecting rod 7 disposed on the surfaces of both the first connecting plate 1 and the first movable shaft 5, the first connecting rod 7 being movably connected to the first connecting plate 1 via a rotating shaft. The first connecting plate 1 is fixedly connected to the first movable shaft. The second connecting plate 2 and the second movable shaft 6 are both provided with second connecting rods 8. The second connecting rods 8 are movably connected to the second connecting plate 2 through a rotating shaft. The second connecting rods 8 are fixedly connected to the second movable shaft. The outer surface of the first connecting plate 1 is provided with a functional compartment 9. The winding roller 10 is movably arranged inside the functional compartment 9 through a rotating shaft. The outer surface of the winding roller 10 is wound with a warning layer 11. The outer surface of the second connecting plate 2 is fixedly provided with a fixing block 12. The side of the warning layer 11 closest to the fixing block 12 is fixedly connected to the fixing block 12.

[0026] A torsion spring 13 is provided between the rotating shaft of the winding roller 10 and the functional compartment 9. This torsion spring 13 causes the winding roller 10 to have an automatic rotation and reset tendency. Thus, when the first connecting plate 1 and the second connecting plate 2 are close to each other, the winding roller 10 will automatically rotate and reset, causing the warning layer 11 to be wound and stored. The warning layer 11 of this device can be made of cloth or metal sheet material. When the first connecting plate 1 and the second connecting plate 2 are far apart, the warning layer 11 can be automatically pulled out. When the first connecting plate 1 and the second connecting plate 2 are close to each other, the torsion spring 13 will drive the winding roller 10 to rotate and wind the warning layer 11.

[0027] The outer surface of the warning layer 11 is provided with reflective strips and warning slogans. The reflective strips and warning slogans can ensure the warning effect of this device. The reflective strips and warning slogans of this device should be printed on the side of the warning layer 11 away from the support leg 17.

[0028] Two first connecting rods 7 are arranged in a cross configuration, and two second connecting rods 8 are arranged in a cross configuration. The first connecting rods 7 and the second connecting rods 8 are movably connected at their midpoints via a pivot. The first connecting rods 7 and the second connecting rods 8 are also movably connected at their adjacent ends via a pivot. The two first connecting rods 7 and the two second connecting rods 8 are movably connected to each other via pivots, so that the first connecting rods 7 and the second connecting rods 8 can form a scissor-type telescopic rod, thereby facilitating the opening or folding of the first connecting plate 1 and the second connecting plate 2. Furthermore, the device is very small in size after folding, making it easy to store.

[0029] Both the first movable shaft 5 and the second movable shaft 6 are provided with a first locking screw 14 by threaded engagement. By tightening the first locking screw 14, the first movable shaft and the second movable shaft can be fixed by friction. When the first movable shaft and the second movable shaft cannot move, the first connecting rod 7 and the second connecting rod 8 cannot open or fold, thereby fixing the warning layer 11.

[0030] A fixing mechanism for fixing the angle of the support leg 17 is provided between the support leg 17 and the mounting shaft 16. The fixing mechanism includes a groove 15, a mounting shaft 16, a support leg 17, a rectangular block 18, a rectangular frame 19, and a spring 20. A groove 15 is provided on one side of the surface of both the first connecting plate 1 and the second connecting plate 2. The mounting shaft 16 is fixedly installed at the lower end of the groove 15. The support leg 17 is movably mounted on the surface of the mounting shaft 16 via a bearing. A rectangular block 18 is fixedly installed at one end of the mounting shaft 16. A rectangular frame 19 is fixedly installed on the outer surface of the support leg 17. A spring 20 is sleeved on the outer surface of the mounting shaft 16. Figure 6 , Figure 7 As shown, when the spring 20 of this device is in a compressed state, when the spring 20 automatically springs up, it can push the rectangular frame 19 to fit onto the outer surface of the rectangular block 18, so that the support leg 17 can be quickly unfolded or folded into the groove 15 for fixation; thus, the angle of the support leg 17 can be easily controlled.

[0031] The fixing mechanism also includes a second locking screw 21. One end of the mounting shaft 16 is screwed with the second locking screw 21 via a threaded connection. This device provides two fixing methods for the support leg 17. The first is a locking fixation, where the rectangular frame 19 is fitted onto the outer surface of the rectangular block 18 to quickly fix the angle of the support leg 17. This locking method provides stable and convenient fixing of the support leg 17, but the structure is relatively complex. The second fixing method of this device is friction fixing, such as… Figure 8 As shown, after the support leg 17 is rotated to a predetermined angle, it is fixed by the tightening friction of the second locking screw 21. The overall structure is simple, but tightening requires tools and fixing relies on friction. There are advantages and disadvantages, and the choice can be made during production.

[0032] Working Principle: Compared to traditional construction warning signs, this device innovatively incorporates a folding function in the warning sign's label section. This design significantly reduces the overall size of the device when folded, making it easy to carry and store. When the warning layer 11 needs to be unfolded, simply pull the first connecting plate 1 and the second connecting plate 2 away from each other, and the warning layer 11 will automatically unfold under the pull, requiring no additional operation. When it needs to be stored, simply bring the first connecting plate 1 and the second connecting plate 2 closer together, and the torsion spring 13 will drive the winding roller 10 to rotate, neatly winding the warning layer 11. This design makes unfolding and storing the warning sign's label section extremely convenient, saving space and greatly improving the device's flexibility in subsequent storage and transportation as the project progresses.

[0033] Furthermore, the folding function of the first connecting plate 1 and the second connecting plate 2 of this device is achieved by tightening or loosening the first locking screw 14, which is simple and reliable to operate.

[0034] After the warning layer 11 is deployed, the support leg 17 also needs to be deployed to ensure the warning effect. The deployment and fixing mechanism of the support leg 17 of this device is designed to be both convenient and practical. This application provides two methods for fixing the support leg 17: the first is a locking fixing method, in which the rectangular frame 19 is fitted onto the outer surface of the rectangular block 18, which can quickly and firmly fix the angle of the support leg 17, ensuring that the support leg 17 remains stable even in harsh environments, but this method is relatively complex in structure; the second is a friction fixing method, in which the support leg 17 is fixed by tightening the second locking screw 21, using the friction between the screw and the contact surface of the support leg 17. This method is simple in structure, but requires tools for tightening, and the fixing effect depends on friction, each with its own advantages and disadvantages. Manufacturers can choose the appropriate fixing method according to actual needs, thereby further improving the applicability and flexibility of this device.
