DETAILED DESCRIPTION

[0018] The embodiment of the present application discloses a portable, detachable and rotatable assembled guardrail. By rotating the rotating column 32 in the rotating drum 31, the protection mechanism 40 between the two support columns 10 can be easily changed in angle. By extending and retracting the telescopic plate 42 on the fixed column 41, the distance between the two support columns 10 can be adjusted, so that the guardrail can be used more flexibly, conveniently avoiding places such as foundation pits, and more convenient to use.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment provides a portable, detachable and rotatable assembled guardrail, comprising two support columns 10, a base 20 is fixedly arranged at the bottom of the two support columns 10, a connecting assembly 30 is arranged on both sides of the two support columns 10, a protective mechanism 40 is arranged between the two connecting assemblies 30, the connecting assembly 30 comprises a rotating cylinder 31, a rotating column 32, an adjusting bolt 33, a connecting rod 34 and a fixing seat 35, the rotating cylinder 31 is arranged on one side of the middle part of the support column 10, the rotating column 32 is movably connected to the inside of the rotating cylinder 31, the two adjusting bolts 33 are respectively threadedly connected to the top and bottom of the rotating cylinder 31, and one end of the two adjusting bolts 33 is in contact with and connected to the rotating column 32, The connecting rod 34 is arranged on the side of the top of the rotating column 32 away from the support column 10, and the connecting rod 34 is in contact with the top of the rotating drum 31. The fixing seat 35 is arranged at the end of the connecting rod 34 away from the support column 10, and the protective mechanism 40 is arranged between the two fixing seats 35. Through the rotation of the rotating column 32 inside the rotating drum 31, the protective mechanism 40 between the two support columns 10 can be conveniently rotated with the rotating column 32, so as to adjust the angle between the two support columns 10, which is convenient for avoiding foundation pits and the like during actual construction. The rotating column 32 is fixed inside the rotating drum 31 by adjusting the threaded connection of the bolt 33 to prevent the protective mechanism 40 from rotating after being fixed.

[0021] Please refer to Figure 1-Figure 4The protective mechanism 40 includes a fixed bar 41, a telescopic plate 42, a movable groove 43, a threaded pin 44, a limiting groove 45, a protective component 46, and a sliding groove 47. The two fixed bars 41 are respectively arranged at the top and bottom of the two connecting components 30. The telescopic plate 42 is inserted and connected to one side of the fixed bar 41, and the fixed bar 41 and the telescopic plate 42 are both arranged between the two connecting components 30. The movable groove 43 is opened on one side of the fixed bar 41, and the telescopic plate 42 is slidably connected to the inside of the movable groove 43. The threaded pin 44 is threadedly connected to the side of the fixed bar 41 away from the middle of the support column 10. A plurality of limiting grooves 45 are opened on the telescopic plate 42 away from the middle of the support column 10. On one side, a plurality of limit grooves 45 are arranged in parallel and equidistantly on one side of the telescopic plate 42, and the threaded pin 44 matches the size of the limit groove 45. The protective component 46 is arranged between the two fixed bars 41 and the two telescopic plates 42. The threaded pin 44 is rotated and extended into the limit groove 45 to fix the fixed bar 41 and the telescopic plate 42 to prevent the fixed bar 41 and the telescopic plate 42 from moving after the guardrail is installed. The telescopic plate 42 slides in the movable groove 43 to change the length of the fixed bar 41 and the telescopic plate 42, thereby changing the distance between the two support columns 10. The length of the guardrail can be conveniently changed according to actual conditions, and it is more flexible to use.

[0022] Please refer to Figure 1-Figure 4The protection assembly 46 includes a fixed rod 461, a first roller 462, and a movable guardrail 463. The plurality of fixed rods 461 are arranged between the two fixed rails 41, and the plurality of fixed rods 461 are arranged in parallel and equidistantly between the fixed rails 41. The first roller 462 is rotatably connected to the outer side of the middle of the fixed rod 461. The movable guardrail 463 is arranged between the two telescopic plates 42. The two slide grooves 47 are respectively opened on one side of the two telescopic plates 42 close to the middle of the support column 10. The movable guardrail 463 includes a movable rod 4631 and a nut 4632. The movable rod 4631 is slidably connected between the two telescopic plates 42, and both ends of the movable rod 4631 are slidably connected to the inside of the slide groove 47. The outer side of the movable rod 4631 is rotatably connected to the second roller, and the two nuts 4632 are respectively threadedly connected to the movable rod 463. 1, and the nut 4632 is in contact with the telescopic plate 42. The first roller 462 and the second roller rotating outside the fixed rod 461 and the movable rod 4631 can convert the force hitting the guardrail into the force for the first roller 462 and the second roller to rotate, so as to prevent the guardrail from being damaged by external collision and effectively reduce the consequences of accidents. The movable rod 4631 and the second roller can be fixed between the two telescopic plates 42 by the nut 4632 outside the movable rod 4631 to prevent the movable rod 4631 from moving at will. The second roller outside the movable rod 4631 is moved to a suitable position by sliding the movable rod 4631 between the two slide grooves 47, so as to prevent a large gap from appearing between the multiple fixed rods 461 and the movable rod 4631, thereby improving the blocking effect of the guardrail and eliminating safety hazards.

[0023] This application can explain its functional principle through the following operation methods:

[0024] When in use, the two support columns 10 and the base 20 are installed at the appropriate position on the construction site, the threaded pin 44 on the top of the fixed column 41 is unscrewed to separate the fixed column 41 from the telescopic plate 42, the telescopic plate 42 slides in the movable groove 43, the telescopic plate 42 is extended from the fixed column 41 to an appropriate length, the overall length of the fixed column 41 and the telescopic plate 42 is adjusted, so as to adjust the distance between the two support columns 10, and then the threaded pin 44 is rotated and the threaded pin 44 is screwed into the corresponding limiting groove 45 to fix the length of the fixed column 41 and the telescopic plate 42, and the nut 4632 on the outer side of the movable rod 4631 is rotated to separate the nut 4632 from the telescopic plate 42, so as to release the fixation of the movable rod 4631 between the two telescopic plates 42, and the movable rod 4631 is slid to the extended telescopic plate 43. The middle position of the retractable plate 42 is used to prevent the movable rod 4631 and the fixed rod 461 from being too far apart and causing safety hazards. Then, the nut 4632 is selected to fix the movable rod 4631 between the two telescopic plates 42. The rotating cylinders 31 on both sides are respectively inserted into the rotating cylinders 31 on the two supporting columns 10, so that the connecting rod 34 on the rotating column 32 contacts the top of the rotating cylinder 31. The adjusting bolt 33 on the outside of the rotating cylinder 31 is rotated so that the adjusting bolt 33 contacts the rotating column 32, and the position and angle of the rotating column 32 in the rotating cylinder 31 are fixed to prevent the rotating column 32 from moving. When the angle needs to be adjusted, the adjusting bolt 33 is unscrewed, and the rotating column 32 is rotated according to the conditions on the construction site so that the protective mechanism 40 on the side of the fixed seat 35 is rotated to a suitable position, and the angle of the guardrail is adjusted to avoid places such as foundation pits.
