[0021] As attached Figure 1 To Attachment Figure 3 As shown:

[0022] The utility model provides a revolving U-shaped ring hinge construction elevator protective door, comprising an elevator protective door 1, a U-shaped ring part 2, a disassembly screw buckle 3 and a fixed steel pipe 4, wherein two U-shaped ring parts 2 are fixedly installed on the elevator protective door 1, and the U-shaped ring part 2 is rotatably connected to the disassembly screw buckle 3 installed on the fixed steel pipe 4.

[0023] The U-shaped ring 2 includes a hinge screw 21, a sleeve 22, a limit bolt 23 and a nut 24. One end of the hinge screw 21 is rotatably mounted in the sleeve 22, and the sleeve 22 is fixedly mounted on the elevator protective door 1; the limit bolt 23 is mounted on the hinge screw 21, and the limit bolt 23 is located above the sleeve 22; the other end of the hinge screw 21 is rotatably connected to the disassembly screw buckle 3; and the other end of the hinge screw 21 is mounted with two nuts 24. The materials of the U-shaped ring 2 are mainly derived from common resources on the construction site, ensuring the effective use of resources.

[0024] The disassembly screw buckle 3 includes a buckle body A31, a pin hole 32, a pin body 33, a buckle body B34, a fastening screw 35 and a fastening nut 36. The buckle body A31 is provided with the pin hole 32, one end of the hinge screw 21 passes through the pin hole 32 and rotates together with it; the buckle body A31 and the buckle body B34 are rotatably installed together through the pin body 33, and the buckle body A31 and the buckle body B34 are installed on the fixed steel pipe 4; the fastening screw 35 fixedly installed on the buckle body A31 passes through the buckle body B34, and the fastening nut 36 is installed on the fastening screw 35. The disassembly screw buckle 3 is easy to operate, and the installation and disassembly processes are particularly simple, which greatly improves the construction efficiency.

[0025] Embodiment 1:

[0026] Specifically, the two ends of the hinge screw 21 are respectively equipped with different thread structures to meet different connection requirements. One end is provided with an external thread that meshes with the nut 24, ensuring that the nut 24 can be tightly fixed on the screw to provide stable support for the hinge. The other end is provided with a screw hole, which matches the limit bolt 23. By screwing in the limit bolt 23, the screw can be fixed and limited to ensure the stability and safety of the hinge. There are two nuts 24, which are respectively located at the upper and lower positions of the pin hole 32, which not only ensures the stability of the hinge in the vertical direction, but also facilitates adjustment during installation and disassembly.

[0027] Specifically, the screw head diameter of the limiting bolt 23 is greater than or equal to the inner diameter of the sleeve 22, and is used to limit the hinge screw 21. When the limiting bolt 23 is screwed into the sleeve 22 and meshes with the screw hole of the hinge screw 21, it will firmly fix the hinge screw 21 to prevent it from unnecessary movement or loosening. This design ensures the stability and reliability of the hinge, and provides a strong guarantee for the safe use of the construction elevator protective door.

[0028] Specifically, the inner sides of the buckle bodies A31 and B34 are provided with arc grooves that fit with the outer surface of the fixed steel pipe 4 , so as to fit tightly with the outer surface of the fixed steel pipe 4 .

[0029] Specifically, the fastening nut 36 installed on the fastening screw 35 is located outside the buckle body B34. The fastening nut 36 is used to limit the buckle body A31 and the buckle body B34. When the fastening nut 36 is tightened, it will reduce the distance between the buckle body A31 and the buckle body B34, so that they can clamp the fixed steel pipe 4 more tightly. On the contrary, when it is necessary to disassemble or adjust, just rotate the fastening nut 36 in the opposite direction to increase the distance between the buckle body A31 and the buckle body B34, which is convenient for operation. This design not only makes the installation and disassembly process simple and quick, but also can effectively ensure the stability and safety of the fixed steel pipe 4.

[0030] Embodiment 2:

[0031] The revolving U-shaped ring hinge is exquisitely designed and consists of a series of high-quality components, mainly the disassembly screw buckle 3, the φ12 screw (hinge screw 21), two nuts (nuts 24) and the φ20 sleeve (sleeve 22). Among them, the φ20 sleeve 24 is precisely welded and firmly installed on the door frame of the construction elevator protective door 1, serving as the fixing cylinder of the hinge to ensure the stability and reliability of the hinge. The φ12 screw serves as the rotating axis of the hinge, is tightly connected to the disassembly screw buckle 3, and is firmly fixed by two nuts, which enhances the durability and safety of the hinge.

[0032] Finally, the screw buckle 3 is disassembled and connected to the steel pipe (fixed steel pipe 4) to form a complete construction elevator protective door hinge system. This system is not only easy to install and operate, but also can be used in a turnover manner, effectively reducing construction costs and improving construction efficiency. At the same time, the hinge has a reasonable design and a compact structure, and can work stably in various construction environments, providing a strong guarantee for the safe use of construction elevator protective doors.

[0033] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
