Description

Technical Field

[0001] This utility model relates to the field of guardrails, and in particular to a guardrail for construction sites. Background Technology

[0002] Guardrails, also known as construction guardrails, are mainly used for isolation and warning. Currently, construction sites commonly use guardrails to enclose foundation pits, building structures, and other architectural features, and their application is very widespread.

[0003] The guardrails in related technologies typically include a support base, on which guardrail frames are welded and fixed. When it is necessary to enclose a construction area, multiple guardrail frames are connected by wires or ropes, and multiple guardrails work together to enclose the construction area.

[0004] Then, some construction areas are not regular rectangular shapes, especially some circular construction areas. Since the guardrails themselves cannot be bent, using multiple guardrails to enclose the construction area will occupy too much non-construction area, which needs to be improved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a construction site guardrail that can be adapted to construction areas of different shapes, so as to improve the problem of guardrails occupying too much non-construction area.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective fence for construction sites, comprising multiple protective frames, with a rotating seat and a rotating tube respectively provided between two adjacent protective frames, and the rotating seat and the rotating tube respectively fixedly connected to the corresponding protective frame, and a rotating shaft vertically fixedly connected to each rotating seat, the rotating shaft passing through the corresponding rotating tube, and enabling the rotating tube to rotate around the corresponding rotating shaft.

[0007] In a preferred embodiment, the present invention can be further configured such that a limiting member is provided between the rotating shaft and the corresponding rotating tube, the limiting member being used to restrict the rotation of the corresponding rotating tube.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the limiting member includes a limiting gear fixedly sleeved on the rotating shaft, a limiting toothed ring is provided inside the rotating tube, a guide block is fixedly connected to the side wall of the limiting toothed ring, a guide groove is provided on the inner wall of the rotating tube for the guide block to slide vertically, and a control member is provided on the rotating tube. The control member is used to control the vertical movement of the limiting toothed ring and to make the limiting toothed ring mesh or separate from the limiting gear.

[0009] In a preferred embodiment, the present invention can be further configured such that: the control component includes two control rods symmetrically fixed on the limiting toothed ring; the rotating tube has two strip holes; the two control rods respectively pass through the corresponding strip holes and respectively slide vertically with the corresponding strip holes.

[0010] In a preferred embodiment, the present invention can be further configured such that: a spring seat is fixedly connected inside the rotating tube, and the spring seat is connected to the limiting tooth ring through a compression spring. The compression spring is used to push the limiting tooth ring to move downward and to make the limiting tooth ring mesh with the limiting gear.

[0011] In a preferred embodiment, the present invention can be further configured such that: each of the protective frames is fixedly connected to a support base at its bottom, and self-locking casters are provided at the four corners of the bottom of the support base.

[0012] In a preferred embodiment, the present invention can be further configured such that a warning light is provided on the top of each of the protective frames.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. Because the guardrail itself can be bent, it can adjust its shape according to the shape of the construction area so that multiple guardrails can fit into the edge of the construction area, preventing the guardrail from occupying too much non-construction area.

[0015] 2. After the positions of two adjacent guardrails are adjusted, the limiting components can restrict the relative rotation of the two adjacent guardrails, thereby reducing the risk of deformation of the guardrail due to external forces and thus improving the protection effect on the construction area.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1 , Figure 2 A construction site safety fence includes multiple protective frames 1. A rotating seat 2 and a rotating tube 3 are respectively provided between two adjacent protective frames 1, and the rotating seat 2 and rotating tube 3 are fixedly connected to their respective protective frames 1. Simultaneously, a rotating shaft 4 is vertically fixedly connected to each rotating seat 2. The rotating shaft 4 passes through the corresponding rotating tube 3, allowing the rotating tube 3 to rotate around the corresponding rotating shaft 4. This means that adjacent protective frames 1 can rotate relative to each other, enabling the safety fence to bend.

[0022] In this embodiment, the protective fence is bendable, allowing it to adjust its shape to fit the edge of the construction area. This prevents the fence from occupying too much non-construction space. Furthermore, the bendable design saves space and facilitates transportation and storage by workers.

[0023] Reference Figure 2 , Figure 3 A limiting component 5 is provided between the rotating shaft 4 and the corresponding rotating tube 3. The limiting component 5 is used to restrict the rotation of the corresponding rotating tube 3. That is, after the positions of two adjacent protective frames 1 are adjusted, the limiting component 5 can restrict the relative rotation of the two adjacent protective frames 1, thereby reducing the risk of deformation of the guardrail under external force and improving the protection effect on the construction area.

[0024] Reference Figure 2 , Figure 3 The limiting component 5 includes a limiting gear 51 fixedly sleeved on the rotating shaft 4, and a limiting toothed ring 52 disposed inside the rotating tube 3. The limiting toothed ring 52 is sleeved on the rotating shaft 4, and a guide block 53 is fixedly connected to the side wall of the limiting toothed ring 52. A guide groove 54 is provided on the inner wall of the rotating tube 3 for the guide block 53 to slide vertically. At the same time, a control component 6 is provided on the rotating tube 3. The control component 6 is used to control the vertical movement of the limiting toothed ring 52 and to make the limiting toothed ring 52 mesh or disengage from the limiting gear 51.

[0025] Reference Figure 2 , Figure 3 The control component 6 includes two control rods 61 symmetrically fixed on the limiting toothed ring 52. The rotating tube 3 has two strip holes 62. The two control rods 61 pass through the corresponding strip holes 62 and slide vertically with the corresponding strip holes 62.

[0026] Reference Figure 2 , Figure 3A spring seat 63 is fixedly connected inside the rotating tube 3. The spring seat 63 is connected to the limiting gear ring 52 through a compression spring 64. The compression spring 64 is used to push the limiting gear ring 52 downward and make the limiting gear ring 52 mesh with the limiting gear 51.

[0027] Pulling the two control levers 61 causes the limiting gear ring 52 to move upward, disengaging it from the limiting gear 51. At this point, the corresponding protective frame 1 can be rotated. Once the protective frame 1 is adjusted to the appropriate position, releasing the control lever 61 causes the limiting gear ring 52 to move downward under the force of the compression spring 64, engaging with the limiting gear 51 and thus fixing the two adjacent protective frames 1.

[0028] Reference Figure 1 Each protective frame 1 has a fixed support 7 at its bottom, and each support 7 has a self-locking caster 8 at one of its four corners to facilitate the movement of the protective railing by staff. Each protective frame 1 is equipped with a warning light 9 at its top to provide nighttime warning and improve the protective effect.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
