The protection frame has a simple structure, can be made of local materials, is easy to support and install, and is convenient to install and disassemble. It not only reduces the risk of high-altitude edge workers falling from a height, but also improves construction efficiency.

[0026] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0027] It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] In this utility model, unless otherwise stated, directional words such as "up, down, left, right" generally refer to the directions in the attached drawings. Figure 1 The upper, lower, left and right shown in the figure are relative to the inner and outer of the outline of each component. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] This embodiment provides a simple edge work protection frame for indoor high-altitude work scenes such as the installation of bay window edge glass. Figure 1 As shown, the protective frame includes: a support rod a1, a support rod b4, a rotating fastener 3 and a fixed clamp 2; the protective frame provides a connection node for the safety rope 5.

[0030] like Figure 1 and Figure 2 As shown, the support rod a1 is provided with two limiting protrusions a11. The two limiting protrusions a11 are spaced apart along the length direction of the support rod a1.

[0031] like Figure 3 As shown, the support rod b4 is provided with a limiting protrusion b41. As an example, the limiting protrusion b41 is cylindrical, with its axis perpendicular to the axis of the support rod b4. The limiting protrusion b41 comprises a large-diameter section and a small-diameter section. The small-diameter section of the limiting protrusion b41 is fixedly connected to the support rod b4, thereby forming a limiting step surface at the transition between the large and small diameter sections.

[0032] In this embodiment, the connection between the limiting protrusion b41 and the support rod b4 is achieved by continuous full welding along the circumference of the limiting protrusion b41, ensuring the integrity and uniformity of the weld, thereby ensuring the connection strength between the limiting protrusion b41 and the support rod b4. In this embodiment, the outer diameter of the small-diameter section of the limiting protrusion b41 is 12 mm. The limiting protrusion b41 is preferably a bolt, which is locally available and easy to install.

[0033] The support rod a1 and the support rod b4 are crossed and rotatably connected in the middle by a rotating fastener 3. In this embodiment, the outer diameter of the support rod a1 and the support rod b4 is 48 mm and the wall thickness is 3 mm. Figure 1 and Figure 5 As shown, when in use, the support rod a1 and the support rod b4 are opened by rotating the rotating fastener 3. The lower ends of the opened support rods a1 and b4 are placed on the ground, and the upper ends are tilted toward the construction wall (the wall where the bay window is located) and then rest against the construction wall.

[0034] In this embodiment, the support rod a1, the support rod b4 and the limiting protrusion a11 are preferably round steel, which can be obtained locally.

[0035] like Figure 1 and Figure 4 As shown, the two ends of the fixed clamp 2 are respectively mounted on the limiting protrusion a11 of the support rod a1 and the limiting protrusion b41 of the support rod b4. One end of the fixed clamp 2 is a U-shaped end 21, and the other end is a ring-shaped end 22. The ring-shaped end 22 of the fixed clamp 2 is coaxially mounted outside the small diameter section of the limiting protrusion b41 on the support rod b4 (it is limited by a limiting step surface). That is, the inner diameter of the ring-shaped end 22 is larger than the outer diameter of the small diameter section of the limiting protrusion b41, and smaller than the outer diameter of the large diameter section of the limiting protrusion b41. The ring-shaped end 22 of the fixed clamp 2 can rotate around the central axis of the limiting protrusion b41, and the large diameter section of the limiting protrusion b41 prevents the ring-shaped end 22 of the fixed clamp 2 from falling out.

[0036] The U-shaped opening of the U-shaped end 21 of the fixed clamp 2 is used to hook the support rod a1, and the U-shaped end 21 is located between the two limiting protrusions a11. The two limiting protrusions a11 limit the U-shaped end 21 to prevent it from falling off the support rod a1. The diameter of the U-shaped end 21 is selected according to the diameter of the support rod a1. The spacing between the two limiting protrusions a11 is selected according to the specifications of the fixed clamp 2. In this embodiment, the outer diameter of the fixed clamp 2 is 10 mm and the length is 820 mm. The opening angle of the support rod a1 and the support rod b4 is greater than 90 degrees (the opening angle is the angle relative to the straight line where the fixed clamp 2 is located), which can improve the stability of the protective frame.

[0037] Both ends of the safety rope 5 are equipped with hooks. One end of the safety rope 5 is installed on the support rod a1, the support rod b4 or the rotating fastener 3 through the hook. The other end of the safety rope 5 is installed on the waist of the operator through the hook.

[0038] Working principle:

[0039] The protective frame in this embodiment is used to ensure the safety of the personnel installing the bay window edge glass.

[0040] The protective frame includes: a working state and a moving state. When the protective frame is in the working state, the support rods a1 and b4 are opened to form a Figure 1 The cross shape shown. The fixed clamp 2 can achieve the limit of the support rods a1 and b4 after they are fully opened, preventing the support rods a1 and b4 from over-expanding, thereby ensuring the stability and safety of the protective frame. After expansion, the lower ends of the support rods a1 and b4 of the protective frame are placed on the ground, and the upper ends are leaning against the construction wall. If the operator misses or falls out of the window due to an unstable center of gravity, the protective frame is pulled by the safety rope 5, and finally the upper and lower ends of the protective frame are both buckled against the construction wall. The safety rope 5 suspends the operator, thereby preventing the operator from falling from a height and ensuring the safety of the operator.

[0041] When the protective frame is in the mobile state, the connection between the fixed clamp 2 and the support rod a1 is released, and the support rod a1 and the support rod b4 are retracted to form a straight-line structure, which is convenient for operators to carry.

[0042] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
