[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1

[0022] like Figure 1-4 The present invention shows a portable roller safety fence, comprising a box 1, a rotating shaft 2 and a fence net 3, wherein the box 1 is vertically arranged, and an opening 101 is vertically arranged on the side wall of the box 1; the rotating shaft 2 is vertically and rotatably arranged in the box 1, wherein the top of the rotating shaft 2 is rotatably connected to the top of the box 1, and the bottom of the rotating shaft 2 is rotatably connected to the bottom of the box 1; a rotating handle 11 is arranged on the top of the box 1, and one end of the rotating handle 11 passes through the top of the box 1 and is fixedly connected to the top of the rotating shaft 2. In addition, Figure 1 As shown, a plurality of posts 4 are arranged evenly and at intervals along the length direction of the fence net 3, each post 4 is arranged vertically, and each post 4 is fixed on the fence net 3, and a retractable tripod 8 is arranged inside each post 4, and the tripod 8 can extend from the bottom of the corresponding post 4. In the present application, the fence net 3 carries all the posts 4 and is wound layer by layer on the outside of the rotating shaft 2 in a spiral shape; wherein the tail end of the fence net 3 is located at the opening 101, and the length of the opening 101 in the vertical direction is greater than or equal to the width of the fence net 3 or the length of the post 4, so as to facilitate the fence net 3 and the post 4 to be pulled out from the opening 101. The fence net 3 in this embodiment is a grid-shaped fence net 3, which has a certain elasticity and can be wound.

[0023] In this embodiment, the box body 1 is cylindrical, and a carrying handle 12 is provided on the side wall of the box body 1. When this embodiment is not in use, all the fence nets 3 and posts 4 are wound around the rotating shaft 2 and are located in the box body 1, and only the tail end of the fence net 3 is at the opening 101 of the box body 1. Therefore, the fence net 3 can be brought to the occasion where it is needed by carrying the box body 1, which is convenient to carry. In addition, the box body 1 in the present application can be made of fiberglass, which is strong and durable. When the fence net 3 is in use, the fence net 3 is pulled out from the opening 101 for enclosure, and the tripod 8 inside the post 4 is pulled out and supported on the ground, such as Figure 1 The support and enclosure of the fence net 3 can be completed. The operation is convenient and quick. After the operation is completed, the tripod 8 at the bottom of the column 4 is stored inside the column 4, and the handle 11 is used to rotate to store the fence net 3 and the column 4 in the box body 1.

[0024] Among them Figure 2 and Figure 3 As shown, in this embodiment, the column 4 is a hollow tube body, and an inner tube 5 is vertically and slidably arranged inside the hollow tube body, and a tripod 8 is arranged at the lower end of the inner tube 5; the tripod 8 includes three legs 80 and a ring 6, and the ring 6 is fixedly sleeved on the outside of the lower end of the inner tube 5, and one end of each leg 80 is rotatably connected to the ring 6. Figure 2As shown, three notches 50 are provided on the outer wall of the lower end of the inner tube 5, and the three notches 50 are arranged at intervals along the circumferential direction of the inner tube 5, and the ring 6 is located outside the notches 50; each leg 80 corresponds to a notch 50, and one end of each leg 80 connected to the ring 6 is rotated and located in the notch 50. Figure 2 As shown, the notch 50 can play a certain role in limiting, storing and stabilizing the legs 80. When the tripod 8 in this embodiment is used, the tripod 8 is first pulled out from the bottom of the column 4. After being pulled out, the lower ends of the three legs 80 are respectively separated from each other and spread out in an outward expansion direction and supported on the ground. After the tripod 8 is supported on the ground, the bottom of the column 4 is pressed on the legs 80. Figure 2 As shown, a support slope 81 is provided at the lower end of the leg 80 near the inner tube 5, and the support slope 81 contacts the ground, thereby ensuring the stability of the support of the tripod 8. In addition, after the tripod 8 is in the open state, its bottom contacts the ground, and due to the gravity of the fence net 3 and the column 4, the tripod 8 is pressed downward, thereby ensuring that the tripod 8 in the expanded state will not be merged together and is stably supported on the ground.

[0025] In addition, Figure 2 and Figure 3 As shown, the lower end of the outer wall of the inner tube 5 is fixedly sleeved with a rubber sleeve 7, and the rubber sleeve 7 is located above the notch 50. The provision of the rubber sleeve 7 can increase the friction between the inner tube 5 and the column 4, that is, the tripod 8 cannot be extended from the column 4 by gravity or the like without the action of external force, but requires artificial external force to extend from the column 4; and after the tripod 8 is manually pulled out of the column 4, it cannot be automatically retracted into the column 4, and it also needs to be manually retracted into the column 4.

[0026] In this embodiment, the column 4 is made of stainless steel, and the upper end of the column 4 is lighter than the lower end, so that it can be windproof and stable.

[0027] In addition, in this embodiment, a warning sign 9 is arranged on the fence net 3, and the warning sign 9 can be made of soft materials such as cloth.

[0028] In this embodiment, one of the posts 4 is located at the tail end of the fence net 3, and a snap-in strip 10 is provided on the outer wall of the post 4 located at the tail end of the fence net 3. The snap-in strip 10 can be snap-fitted with the side wall of the opening 101, so as to facilitate pulling the fence net 3 out of the opening 101, wherein the snap-in strip 10 is prior art.

[0029] The present application is used in industries such as electricity, urban roads, and chemical accident sites, and has the advantages of being portable and lightweight. One person can carry it and go, and the rescue is quick. It saves more than 85% of the working hours compared to carrying traditional weight-type fences, and is convenient for quickly entering the working state. In addition, the fence net 3 in this embodiment can be made of a red and white cross-mesh nylon net, which has an obvious warning effect and bright and eye-catching colors; the grid design allows construction and rescue to be seen through the grid, which makes it easier for hurried pedestrians to quickly make detour decisions and avoid secondary dangers.

[0030] Embodiment 2

[0031] The shape and structure of this embodiment are the same as those of the first embodiment. In addition, the height of the box 1 in this embodiment is 120 cm, the total length of the fence net 3 can be stretched to 300 meters, and a total of 10 columns 4 are set. The total weight of the utility model is 4 kg. In addition, the height of the column 4 is 90 cm and the outer diameter is 3 cm; the height of the inner tube 5 is 55 cm and the outer diameter is 2.5 cm; the outer diameter of the rubber sleeve 7 is 2.8 cm, and the thickness of the rubber sleeve 7 is 0.3 cm; the height of the leg 80 is 30 cm. The leg 80 is made of stainless steel.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
