DETAILED DESCRIPTION

[0023] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0024] See also Figure 1-3A safety belt hanging device includes a base 101, and base legs 102 are fixed at the top four corners of the base 101; a manual tightening mechanism 201 is installed on the upper part of the two base legs 102 on the same side, and a fixed rubber pad 104 is arranged on the inner side wall of the base leg 102 on the opposite side of the manual tightening mechanism 201; the manual tightening mechanism 201 cooperates with the fixed rubber pad 104 and fixes the entire hanging device on the building; a hanging ring 4 for hanging the safety belt is fixed at the bottom end of the base 101. This device can be conveniently and reliably fixed on the door and window opening wall or beam of the building structure body as a hanging point for hanging the safety belt, effectively avoiding the safety hazards caused by the lack of suitable hanging points on site, thereby meeting the safety belt use requirements of all secondary structures and decoration construction stages on site, and ensuring the safety of operations. During specific use, the entire suspension device is fixed to the building by the manual tightening mechanism 201 in conjunction with the fixed rubber pad 104, thereby achieving the fixation of the entire suspension device, and then the safety belt is hung on the suspension ring 4 to ensure the safety of subsequent construction operations.

[0025] Furthermore, the base 101 and the base legs 102 are both cut from steel plates. The above steel plates can effectively reduce the design and manufacturing costs. The steel plates can be waste steel plates from the construction site.

[0026] Furthermore, an arc-shaped reinforcing plate 103 is welded between the base 101 and the base legs 102. The arc-shaped reinforcing plate 103 enhances the strength of the connection structure between the base 101 and the base legs 102.

[0027] Furthermore, the manual tightening mechanism 201 includes a nut seat 5 fixed to the outer wall of the upper part of the base leg 102, a tightening screw 6 is installed inside the nut seat 5 through threaded transmission, a crank structure is fixed to the outer end of the tightening screw 6, and a tightening plate 8 is installed on the inner end of the tightening screw 6 through the rotation limit of the screw 3. The above-mentioned manual tightening mechanism 201 can be used to fix the entire suspension device on the building. In the specific fixing process, by operating the crank structure, the tightening screw 6 is driven by the crank structure, and the tightening screw 6 is extended through the cooperation between the tightening screw 6 and the nut seat 5, and then the tightening plate 8 is tightened to the surface of the building.

[0028] Further, the crank structure comprises a vertical arm 7 fixed on the jacking screw 6, and a rotating handle 9 is fixed to the end of the vertical arm 7. The crank structure can be used to pass the jacking power.
