DETAILED DESCRIPTION

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a foundation pit safety fence includes a column 1, a support leg 2, a pair of connecting rods 3, a guardrail 4 and a connecting piece 5.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the column 1 is vertically arranged on the ground, the support leg 2 is arranged at the lower end of the column 1, and the upper end is rotatably connected to the two sides of the column 1, and when rotated to a vertical state, the outer wall of the support leg 2 is flush with the outer wall of the column 1. One end of a pair of connecting rods 3 is rotatably connected to each other, and the other end is rotatably connected to the inner side wall of the lower end of the support leg 2, and the pair of connecting rods 3 is used to support the support leg 2 when rotating to a horizontal state.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the guardrail 4 is divided into two layers and is arranged on both sides of the column 1. The guardrail 4 includes multiple sections of tube bodies 41 that are sleeved with each other, and the tube bodies 41 are slidably connected to each other. Grooves 11 are provided on both sides of the column 1. The outermost tube body 41 is rotatably connected to the upper end of the groove 11 and is used to be flipped and embedded in the groove 11. A clamping block 12 is provided in the groove 11 to clamp the outermost tube body 41, which is used to fix the guardrail 4 when it is stored.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the connecting member 5 is arranged between the ends of two adjacent guardrails 4, and the connecting member 5 includes an insertion rod 51 and an insertion tube 52. The insertion rod 51 and the insertion tube 52 are respectively arranged at the end positions of the guardrails 4 on the same layer, and are used for mutual insertion. A hook 53 is arranged on the insertion rod 51, and a clamping hole 54 for the hook 53 to be embedded is arranged on the insertion tube 52.

[0031] When the fence needs to be assembled, the column 1 is placed upright on the ground, and then the support leg 2 is controlled to flip outward. At the same time, the support leg 2 drives the connecting rod 3 to move synchronously until the connecting rod 3 rotates to a horizontal state. The connecting rod 3 and a pair of support legs 2 are arranged in a triangle. At this time, a heavy object can be pressed on the connecting rod 3 to achieve the installation and fixation of the entire column 1.

[0032] Then, the guardrail 4 is controlled to flip outward to a horizontal state, and then the guardrail 4 is pulled to extend the guardrail 4. Then, the insertion tube 52 is inserted into the insertion rod 51 aligned with each other, and the hook 53 is embedded in the clamping hole 54 to achieve the connection between adjacent guardrails 4, completing the convenient assembly and use of the entire fence.

[0033] When the fence needs to be disassembled and transported, the hook 53 is first disassembled, and then the guardrail 4 is controlled to retract, and the guardrail 4 is controlled to flip and embed into the groove 11, and the guardrail 4 is fixed by the block 12, so that the guardrail 4 is stored.

[0034] Then, the weight is removed from the connecting rod 3, and then the connection position of the pair of connecting rods 3 is controlled to move upward, so that the lower ends of the legs 2 are close to each other. When the legs 2 are flipped to a vertical state, the connecting rod 3 is located between the legs 2, and the legs 2 are stored.

[0035] Therefore, after the fence is stored, it presents a long columnar structure, and all other components are stored, which reduces the space occupied by the fence, makes the transportation and handling process of the fence easier and more convenient, and has the effect of facilitating transportation and construction.

[0036] like Figure 1 , Figure 2 As shown, a protective cloth 6 is arranged between the upper and lower guardrails 4, and sleeves 61 are arranged on the upper and lower ends of the protective cloth 6 and sleeves 61 are arranged on the guardrail 4, and a receiving cavity 13 for receiving the protective cloth 6 and the sleeve 61 is vertically arranged on the upper end surface of the column 1.

[0037] By arranging a freely detachable protective cloth 6 between the guardrails 4, it can be adapted to different usage scenarios and improve practicality. At the same time, the protective cloth 6 can be stored in the column 1, which is convenient for engineering handling and transportation of the protective cloth 6.

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, a protrusion 14 is provided on one side of the column 1, and a concave hole 15 for the protrusion 14 to be embedded is provided on the other side, so as to realize the stacking storage and transportation of the columns 1 and ensure the stability during stacking to prevent collapse.

[0039] like Figure 1 , Figure 2 As shown, a handle 16 is provided at the upper end of the column 1 to facilitate lifting and carrying of the column 1, making the transportation process more convenient.

[0040] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
