DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a temporary guardrail for construction, comprising a first column 1 and a second column 2, the first column 1 and the second column 2 are symmetrically arranged, and the bottoms of the first column 1 and the second column 2 are fixedly connected with a support plate 3.

[0021] The second column 2 is located on one side of the first column 1 and is provided with a U-shaped groove. A rotating shaft 4 is rotatably connected to the second column 2 through a bearing. Steel wire ropes 5 are equidistantly connected between the first column 1 and the second column 2. One end of the steel wire rope 5 is wound around the outside of the rotating shaft 4, and the other end of the steel wire rope 5 is fixedly connected to the first column 1. A reinforcing connection mechanism 17 is provided at the top end between the first column 1 and the second column 2.

[0022] It should be noted that when the utility model is used, the distance between the first column 1 and the second column 2 is adjusted according to the required length of the enclosure. The connecting rod 16 on the first column 1 and the second column 2 can be selected with a suitable length as needed. The first column 1 and the second column 2 are pulled apart, the threaded connection tube 15 is rotated to a position perpendicular to the second column 2, and then one end of a suitable connecting rod 16 is threadedly connected to the threaded connection tube 15, and the connecting rods 16 on the first column 1 and the second column 2 are threadedly connected through the threaded sleeve 9, so that the first column 1 and the second column 2 are fixed by the two connecting rods 16, and then the length of the wire rope 5 is adjusted to make the wire rope 5 between the first column 1 and the second column 2 in a tensioned state. When adjusting, only the rotating handle 18 needs to be rotated. The worm 11 is rotated, and the rotating shaft 4 is rotated through the meshing connection between the worm 11 and the worm wheel 10, so that the wire rope 5 between the first column 1 and the second column 2 is tightened, and multiple wire ropes 5 cooperate with the connecting rod 16 to form a fence. When not in use, the rotating handle 18 is rotated in the opposite direction to appropriately loosen the wire rope 5 between the first column 1 and the second column 2, and then the threaded sleeve 9 is rotated to disconnect the two connecting rods 16, so that the first column 1 and the second column 2 are only connected by the wire rope 5, and then the turntable 7 is rotated to rotate the fixing box 6 and its bottom support tube 8 180 degrees, and then the connecting rod 16 is rotated to make the end of the connecting rod 16 droop vertically, and finally the first column 1 and the second column 2 are placed together, so that the overall volume of the guardrail becomes smaller, and the guardrail can be directly lifted to transfer its position.

[0023] The reinforcement connection mechanism 17 includes a fixed box 6, a threaded sleeve 9, a threaded connection tube 15 and a connecting rod 16. The top of the second column 2 is rotatably connected to the support tube 8 through a bearing, and the top of the support tube 8 is fixedly connected to the fixed box 6. The outer side of the fixed box 6 is connected to the mounting plate 13, and the side of the mounting plate 13 away from the fixed box 6 is fixedly connected to the threaded connection tube 15. The threaded connection tube 15 is internally threaded with a connecting rod 16. A threaded sleeve 9 is connected between the two connecting rods 16. The spiral rotation directions of the two ends of the threaded sleeve 9 are opposite, and the ends of the two connecting rods 16 are respectively threadedly connected to the two ends of the threaded sleeve 9.

[0024] It should be noted that the connecting rod 16 and the fixing box 6 are detachably connected. When connecting the connecting rod 16, it is only necessary to rotate the threaded connecting tube 15 on the mounting plate 13 to make it perpendicular to the fixing box 6, and then thread one end of the connecting rod 16 is connected to the threaded connecting tube 15. The connecting rod 16 and the threaded connecting tube 15 are tightly connected to fix the connecting rod 16. When the connecting rods 16 on the first column 1 and the second column 2 are connected, the two connecting rods 16 are connected and fixed by means of the threaded sleeve 9, so that the first column 1 and the second column 2 are reinforced and fixed by the two connecting rods 16.

[0025] A mounting groove 12 is provided at the bottom end of the outer side of the fixing box 6 , and a rotating shaft is rotatably connected in the mounting groove 12 . A mounting plate 13 is located on one side of the mounting groove 12 and is fixedly connected to a connecting block 14 , and an end of the connecting block 14 is fixedly connected to the rotating shaft in the mounting groove 12 .

[0026] It should be noted that the connecting block 14 on the mounting plate 13 is rotatably connected to the inside of the mounting groove 12 via a rotating shaft, and the threaded connecting tube 15 is fixedly connected to the mounting plate 13, so that the threaded connecting tube 15 can be adjusted to a horizontal position by rotating the mounting plate 13, thereby facilitating the connection of the connecting rod 16 therewith.

[0027] The top of the rotating shaft 4 passes through the second column 2 and the supporting tube 8 and extends into the fixed box 6. The rotating shaft 4 is located on the outer side of one end inside the fixed box 6 and is fixedly connected to a worm gear 10. A worm 11 is rotatably connected to the fixed box 6 through a bearing. The worm 11 and the worm wheel 10 are meshed and connected. The end of the worm 11 passes through the fixed box 6 and is fixedly connected to a rotating handle 18.

[0028] It should be noted that the worm 11 is rotated by rotating the handle 18, and the worm wheel 10 is rotated by the meshing connection between the worm 11 and the worm wheel 10. The rotation of the worm wheel 10 drives the rotation of the rotating shaft 4, so that the winding or unwinding of the wire rope on the rotating shaft 4 can be controlled by the forward or reverse rotation of the rotating shaft 4.

[0029] The interior of the support plate 3 is a hollow structure, and a counterweight plate is arranged inside the support plate 3 .

[0030] It should be noted that by arranging a counterweight plate inside the support plate 3, the weight of the support plate 3 can be increased, making the support of the guardrail more stable.

[0031] A rotating disk 7 is fixedly connected to the top of the fixed box 6 .

[0032] It should be noted that the rotation of the fixing box 6 can be controlled by rotating the turntable 7, so that the orientation of the connecting rod 16 can be adjusted, which facilitates the drooping of the end of the connecting rod 16 and realizes the folding of the guardrail for easy carrying and storage.
