Description

Technical Field

[0001] This utility model relates to the field of railing protection technology, and in particular to a double-layer protective steel structure railing. Background Technology

[0002] In numerous scenarios such as construction sites, industrial areas, and public areas, railings serve as crucial safety protection facilities, their performance directly impacting the safety of people and property. However, traditional railings exhibit significant limitations in practical applications, particularly in their height adjustment and modularity, failing to meet the demands of modern, diverse scenarios. Conventional railings have a fixed height, lacking flexible adjustment capabilities. In public activity venues such as schools and stadiums, varying crowd sizes and event content necessitate different height requirements for railings, and traditional railing splicing methods present numerous problems. While common welding splicing methods offer high connection strength, they require specialized welding equipment and skilled personnel, making the process cumbersome and time-consuming. Once welding is complete, the railing's length and layout are essentially fixed. Subsequent disassembly and reassembly based on site changes or functional adjustments are extremely difficult and may even lead to railing damage. Therefore, a double-layered protective steel structure railing is needed. Utility Model Content

[0003] The main purpose of this utility model is to provide a double-layer protective steel structure railing that can effectively solve the problem of not being able to raise or lower.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A double-layer protective steel structure railing includes an installation plate.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 As shown, a double-layer protective steel structure railing includes a mounting plate 1. A rotating mechanism 2 is fixedly connected to the upper end of the mounting plate 1. Lifting components 3 are fixedly connected to the left and right sides of the upper end of the rotating mechanism 2. Several I-shaped plates 5 are rectangularly distributed and fixedly connected to the rear sides of the opposite faces of the two lifting components 3. Several guard plates 6 are fixedly connected to the front of the opposite faces of the two lifting components 3. Two warning signs 7 are fixedly connected to the left and right sides of the front ends of the guard plates 6.

[0017] In the specific implementation process of this utility model, firstly, the entire device is installed in a suitable position using the mounting plate 1. Then, the internal structure of the rotating mechanism 2 is rotated according to the required height. The operation of the internal structure of the rotating mechanism 2 drives the internal structure of the lifting component 3 to rise upward. Then, the internal structure of the two lifting components 3 rises, driving the I-shaped plate 5 and the guard plate 6 to rise, so that the warning sign 7 reaches a suitable height to play a warning role. Then, the internal structure of the lifting component 3 on the right end of the other device slides into the inner cavity of the buckling mechanism 4. Then, the internal structure of the buckling mechanism 4 is rotated to fix the spliced ​​device in place, thereby achieving the purpose of splicing.

[0018] Specifically, in order to achieve the purpose of driving the internal structure of the lifting component 3, refer to Figure 2In this scheme, the rotating mechanism 2 includes two fixed boxes 21, which are respectively fixedly connected to the left and right sides of the upper end of the mounting plate 1. A support box 25 is fixedly connected to the rear side of the opposite surfaces of the two fixed boxes 21. A rotating rod 26 is rotatably connected to the inner cavity of the support box 25. Worm gears 22 are rotatably connected to the front side of the middle of the bottom wall of the two fixed boxes 21. Worms 23 are meshed with the rear side of the outer surface of the two worm gears 22. A gear set 24 is fixedly connected to the left side of the outer arc surface of the right worm 23. Both gear sets 24 are composed of two meshing bevel gears.

[0019] Furthermore, the left and right ends of the rotating rod 26 both penetrate the outer surface of the same side fixing box 21 and are fixedly connected to the two worm gears 23 at their close ends.

[0020] In the above, rotating the turntable at the top of the fixed box 21 on the right side drives the bevel gear to rotate, which in turn drives the worm gear 23 to rotate, which in turn drives the rotating rod 26 to rotate, thereby driving the two worm wheels 22 to rotate, which in turn drives the internal structure of the lifting assembly 3 to operate.

[0021] Specifically, in order to achieve the purpose of raising and lowering the entire device, refer to Figure 2 and Figure 3 In this solution, the lifting assembly 3 includes two support columns 31, which are respectively fixedly connected to the upper end of the fixed box 21 on the same side. The bottom wall of the inner cavity of each of the two support columns 31 is rotatably connected with a lead screw 32, and the outer surface of each of the two lead screws 32 is threaded with a slider 33. The right end of the support column 31 on the right side is fixedly connected with a recess 34, and the ends of the two support columns 31 that are close to each other are slidably connected with a sliding plate 35.

[0022] Furthermore, both the upper ends of the slide plate 35 and the slider 33 on the same side are fixedly connected to a fixing plate 36.

[0023] In the above, the worm gear 22 rotates to drive the lead screw 32 to rotate, and the lead screw 32 drives the slider 33 to rise in the inner cavity of the support column 31 while rotating. As the support column 31 rises, it pushes the fixed plate 36 upward, so that the two fixed plates 36 drive the two sliding plates 35 to slide on the surface of the support column 31, thereby achieving the purpose of the support column 31 driving the I-shaped plate 5 and the guard plate 6 to rise.

[0024] Specifically, in order to achieve the goal of splicing, refer to Figure 4 and Figure 5In this solution, the buckling mechanism 4 includes a recessed box 41, which is fixedly connected to the left end of the support column 31 on the left side. A partition 43 is fixedly connected to the middle of the inner cavity of the recessed box 41. Several sliding grooves 44 are rectangularly distributed on the outer surface of the partition 43. Hooks 45 are fixedly connected to the inner cavity of each of the sliding grooves 44. A rotating column 42 is rotatably connected to the rear side of the bottom wall of the inner cavity of the recessed box 41. Several buckling components 46 are fixedly connected to the outer surface of the rotating column 42 in a rectangular distribution.

[0025] Furthermore, the buckle assembly 46 includes a square plate 461 and two levers 465. The square plate 461 fixes the rear wall of the inner cavity of the recessed box 41. A spring 462 is fixedly connected to the lower end of the square plate 461. A cylinder 463 is fixedly connected to the lower end of the spring 462. Two inclined grooves 464 are symmetrically opened on the outer surface of the cylinder 463 away from its axis. The two levers 465 are symmetrically distributed and fixedly connected to the outer surface of the rotating column 42.

[0026] In the above process, firstly, the handle at the upper end of the concave box 41 is rotated to drive the rotating column 42 to rotate. At the same time as the rotating column 42 rotates, the lever 465 rotates, causing the lever 465 to slide on the surface of the inclined groove 464. This causes the cylinder 463 to compress the spring 462 and lift upward. Then, the concave block 34 of another device slides into the inner cavity at the front of the concave box 41, so that the groove inside the concave block 34 corresponds to the sliding groove 44. Then, the handle is rotated back to the initial position, causing the lever 465 to leave the surface of the inclined groove 464. Then, under the action of the spring 462, the cylinder 463 is pushed down, which in turn causes the hook 45 to hook into the groove inside the concave block 34, thereby achieving the purpose of fixing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
