[0002] The landscaping project is a project for constructing landscape gardens. When constructing the landscaping, construction fences are needed to warn pedestrians and vehicles to prevent pedestrians or vehicles from entering the construction site and causing danger. When the traditional fence is in use, it is connected to the hanging ring on the adjacent fence through the hook on one side of the fence, so as to realize the mutual connection of multiple fences.

[0003] For the traditional warning fence for a garden construction site, welded hooks and hanging rings are generally used as connecting pieces to realize the rapid assembly between fence units. The hooks welded on the surface of the fence are extremely vulnerable to the collision and impact of the complex construction site environment due to the protruding design, resulting in deformation or even fracture. Since the hook and the fence are integrally formed by welding, once the hook is damaged, it is usually necessary to replace the entire fence unit or perform welding repair, which increases the construction cost, prolongs the maintenance time, and affects the construction progress. Therefore, a warning fence for a construction site is proposed for the above situation. Content of the Utility Model

Damping rotating shafts are arranged at both ends of the movable rod. The movable rod is rotationally matched with a pair of circles through a pair of damping rotating shafts. An assembly groove is opened on the movable rod. A stepped hole is opened on the inner wall of the assembly groove. The stepped hole communicates with the outer wall of the fence main body. A movable stepped rod is arranged in the stepped hole. A spring is sleeved on the stepped rod. One end of the stepped rod extends out of the stepped hole. A threaded hole is opened at the bottom of the fence main body.

[0007] One side of the first connecting piece is provided with a fixing plate. The fixing plate is inserted into the assembly groove. A positioning hole is opened on one side of the fixing plate. The positioning hole cooperates with one end of the stepped rod.

[0008] A convex rod is arranged at the top of the base. The convex rod is in threaded cooperation with the threaded hole.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Referring to Figures 1-4 , a warning fence at the construction site includes a fence main body 1. A pair of circular holes are opened on the fence main body 1. Damping rotating shafts 1003 are provided at both ends of the movable rod 101. The movable rod 101 is rotationally matched with a pair of circles through a pair of damping rotating shafts 1003. An assembly groove 1001 is opened on the movable rod 101. A stepped hole 1002 is opened on the inner wall of the assembly groove 1001. The stepped hole 1002 communicates with the outer wall of the fence main body 1. A movable stepped rod 2 is provided in the stepped hole 1002. A spring 3 is sleeved on the stepped rod 2. One end of the spring 3 is fixedly connected to the inner wall of the stepped hole 1002. One end of the stepped rod 2 extends out of the stepped hole 1002. A threaded hole 103 is opened at the bottom of the fence main body 1.

[0024] A fixing plate 5 is provided on one side of the first connecting member 4. The fixing plate 5 is inserted into the assembly groove 1001. A positioning hole 501 is opened on one side of the fixing plate 5. The positioning hole 501 cooperates with one end of the stepped rod 2.

[0025] A convex rod 601 is provided on the top of the base 6. The convex rod 601 is in threaded cooperation with the threaded hole 103.

[0026] In this embodiment, during use, when the first connecting member 4 is broken and needs to be replaced, the staff pulls the stepped rod 2 through the handle. After the stepped rod 2 is subjected to the pulling force, it contracts into the stepped hole 1002. At this time, the stepped rod 2 will compress the spring 3, and at the same time, one end of the stepped rod 2 extends out of the positioning hole 501. The staff can then pull out the first connecting member 4 from the inside of the assembly groove 1001. After replacing the new first connecting member 4, when the fixing plate 5 at the end of the first connecting member 4 is inserted into the assembly groove 1001 and abuts against the inner wall of the assembly groove 1001, the handle is released. Under the reset of the spring 3, the stepped rod 2 moves into the positioning hole 501, thereby completing the positioning.

[0027] When the device is used and then stored and transported, the staff rotates the base 6 so that the base 6 rotates from the original state perpendicular to the fence main body 1 to a state parallel to the fence main body 1, which can facilitate the stacking of the whole device, reduce the occupied space, and achieve the benefit of facilitating transportation. Then, the movable rod 101 is rotated, so that the movable rod 101 drives the first connecting member 4 to rotate 180° after rotation, thereby avoiding the first connecting member 4 protruding outside the fence main body 1 and reducing the collision damage during transportation.

[0028] In this embodiment, as Figure 1 、 Figure 2and Figure 4 As shown in Figure 4 , at one end of the outer wall of the fence main body 1 away from the first connecting member 4, a second connecting member 401 is provided. The second connecting member 401 is a rectangular block, and a round hole is penetrated through the second connecting member 401.

[0029] In this embodiment, the first connecting member 4 is a hook, and the hook cooperates with the round hole to realize the assembly of multiple fence main bodies 1, and the installation method of the second connecting member 401 is the same as that of the first connecting member 4.

[0030] In this embodiment, as Figure 4 shown, an external thread is provided on the outer wall of the convex rod 601.

[0031] In this embodiment, by providing an external thread on the convex rod 601, it can further cooperate with the threaded hole 103 to realize the rotation of the base 6 and achieve the function of adjusting the angle.

[0032] In the above embodiment, the base 6 is in an inverted "U" shape.

[0033] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, a circular handle is provided at one end of the stepped rod 2 extending out of the stepped hole 1002.

[0034] In this embodiment, the circular handle is provided to facilitate the operation of the stepped rod 2 by the staff.
