Description

Technical Field

[0001] This utility model relates to a fence, specifically a municipal construction fence that is easy to store, and belongs to the field of fence technology. Background Technology

[0002] Municipal construction fences are key facilities for ensuring construction safety and order. They effectively isolate work areas, prevent pedestrians and vehicles from accidentally entering dangerous areas, protect public safety, regulate the construction scope, reduce dust and noise pollution, maintain urban order and cleanliness, and enhance the image of civilized construction.

[0003] A search revealed a Chinese patent with publication number CN214740478U that discloses a protective fence for municipal road construction that is easy to store. The fence includes a first railing and a first protective plate. A light is installed on the top of the first railing, and a protective shell is installed on the inner side of the railing. The inner wall of the protective shell is fitted with blades, and a rotating shaft is connected to the middle of the blades. Slider blocks are connected to both sides of the protective shell.

[0004] While the above solution allows for quick disassembly, there is still room for improvement in practical applications. Because the current device needs to be disassembled into multiple independent parts for storage, it is not only inconvenient to transport and store, but also requires reassembly during use, increasing labor costs and thus reducing storage convenience. To address these issues, we provide a municipal construction fence that is easy to store. Utility Model Content

[0026] This utility model provides a municipal construction fence that is easy to store.

[0027] Please see Figure 1 and Figure 2 The device includes hollow column 1 and hollow column 2. Both hollow column 1 and hollow column 2 have power supplies installed inside, which can supply power to the electrical equipment in this application. Both hollow column 1 and hollow column 2 have drive motors and rotary motors fixedly installed inside. The output end of the drive motor is fixedly connected to the active rod 303, and the output end of the rotary motor is fixedly connected to the adjusting screw 306. Both drive motors and rotary motors are common electrical devices in the prior art, so they are not shown in the figure. This application will not elaborate on their models and internal structures. They can also be replaced by other power sources or manually driven active rod 303 and adjusting screw 306.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4The hollow column 1 has a fence mechanism 3 inside. The fence mechanism 3 includes a load-bearing plate 301. The outer surface of the load-bearing plate 301 is slidably connected to the hollow column 1. The top surface of the load-bearing plate 301 is rotatably connected to a sprocket 302. The inner wall of the sprocket 302 is slidably connected to a drive rod 303. The outer surface of the sprocket 302 is driven by a chain 304. The outer surface of the chain 304 is driven by a sprocket 305. The bottom surface of the sprocket 305 is rotatably connected to the load-bearing plate 301. The outer surface of the drive rod 303 is provided with a sliding groove. The sprocket 302 is fixedly installed inside the sprocket 302. So that the drive rod 303 drives the sprocket 302 to rotate without affecting the drive of the load-bearing plate 301 to drive the sprocket 302 to move up and down.

[0029] An adjusting screw 306 is rotatably connected to the inner wall of the hollow column 1. The outer surface of the adjusting screw 306 is threadedly connected to the bearing slide plate 301. By driving the adjusting screw 306 to rotate, the bearing slide plate 301 can be driven to slide vertically in the inner wall of the hollow column 1 in sync.

[0030] A winding roller 307 is fixedly connected to the top surface of sprocket 2 305, and a fence body 308 is fixedly connected to the outer surface of winding roller 307. By driving winding roller 307 to rotate, the fence body 308 can be wound up and unwound.

[0031] A sprocket 309 is fixedly connected to the outer surface of the drive rod 303. A chain 2 310 is driven to the outer surface of the sprocket 309. A sprocket 4 311 is driven to the outer surface of the chain 2 310. The bottom surface of the sprocket 4 311 is rotatably connected to the hollow column 1. By driving the chain 2 310, the sprocket 4 311 can be driven to rotate simultaneously.

[0032] A take-up roller 312 is fixedly connected to the top surface of sprocket 4 311, and a rope 313 is fixedly connected to the outer surface of take-up roller 312. By driving sprocket 4 311 to rotate, take-up roller 312 can be driven to rotate simultaneously, effectively winding and unwinding the rope 313.

[0033] A connecting plate 314 is fixedly connected to one end of the fence body 308 away from the winding roller 307. The outer surface of the connecting plate 314 is slidably connected to the hollow column 2. Both the outer surfaces of the connecting plate 314 and the hollow column 2 are provided with screw holes, so that the connecting plate 314 can be fixed to the surface of the hollow column 2 with bolts. A connecting plate 315 is fixedly connected to one end of the rope 313 away from the winding roller 312. The outer surface of the connecting plate 315 is provided with threaded holes. The setting of the connecting plate 315 effectively supports and limits the rope 313.

[0034] Please refer to it again. Figure 1Warning lights 4 are fixedly connected to the top surfaces of both hollow column 1 and hollow column 2. Warning strips 5 are fixedly connected to the outer surface of the fence body 308. During the day, the bright colors of the warning strips 5 enhance visual warning, and at night, the warning lights 4 provide illumination to prevent pedestrians from accidentally entering, effectively ensuring 24-hour visibility, reducing the risk of accidents, and further enhancing the safety of the device.

[0035] Working Principle: When the entire device needs to be stored, firstly, unscrew the bolts between connecting plate 314 and hollow column 2 to detach connecting plate 314 from hollow column 2. Then, start the rotating motor inside hollow column 1 to drive the adjusting screw 306 to rotate. The rotation of adjusting screw 306 causes the bearing slide plate 301 to slide down inside hollow column 1. The sliding of bearing slide plate 301 causes the take-up roller 307 to move down synchronously and be retracted into hollow column 1. At the same time, start the drive motor inside hollow column 1 to drive the drive rod 303 to rotate. The rotation of drive rod 303 drives sprocket 302 and sprocket 309 to rotate synchronously. The rotation of sprocket 302 and sprocket 309, combined with the synergistic effect of chain 304 and chain 310, effectively drives sprocket 305 and sprocket 311 to rotate simultaneously. The rotation of sprockets 2 (305) and 4 (311) drives the rotation of take-up rollers 1 (307) and 2 (312). The rotation of take-up rollers 1 (307) and 2 (312) effectively retracts the fence body 308 and the rope 313 until they are completely retracted into the hollow post 1. At this point, the side of the hollow post 2 (2) will fit against the hollow post 1, thus allowing the device to flexibly control its overall length and height according to requirements. This optimization not only facilitates the maintenance of the construction site but also makes the device easier to store, effectively avoiding the problem of disassembly required for storage in traditional devices. Furthermore, during use, the bright colors of the warning strip 5 enhance visual warning during the day, and the warning light 4 provides illumination at night to prevent pedestrians from accidentally entering, effectively ensuring 24-hour visibility and reducing the risk of accidents.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
