Description

Safety belt tying and hanging device Technical Field The utility model relates to the technical field of building construction, in particular to a safety belt tying and hanging device. Background In building construction, the safety of site construction operators is the important importance of construction management, and safety accidents easily occur because safety belts (ropes) cannot find a tying place when the workers construct at the adjacent side positions. At present, most sites are provided with fastening points of safety belts (ropes), and the problems that safety protection is not standard or can not be recycled are easy to occur by adopting methods of fixing iron rings through expansion bolts, knotting through bolt holes of steel wire ropes, hooking steel bars and the like. The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of utility model The utility model aims to provide a safety belt fastening device which can be reused and has high safety. The utility model provides a safety belt tying and hanging device, which comprises a screw, a circular ring, a first nut and a steel plate, wherein one end of the screw is provided with threads, the other end of the screw is provided with a pin shaft and a hollow groove, the pin shaft penetrates through the hollow groove, the circular ring comprises a connecting structure with first internal threads, the first internal threads are matched with the threads on the screw, the circular ring is connected with the screw through the first internal threads, the first nut is internally provided with second internal threads matched with the threads on the screw, the first nut is connected with the screw through the second internal threads and is positioned between the pin shaft and the circular ring, and the steel plate can be accommodated in the hollow groove and is rotationally connected with the pin shaft. In one or more embodiments, a washer is provided at an end of the first nut adjacent to the steel plate. In one or more embodiments, the steel plate is provided with a long hole, and the width of the long hole is matched with the diameter of the pin shaft. In one or more embodiments, the long hole is located at a middle portion of the steel plate and is disposed along a length direction of the steel plate. In one or more embodiments, the length of the steel plate is greater than the depth of the hollowed out groove. In one or more embodiments, the width of the hollowed groove is greater than or equal to the width of the steel plate. In one or more embodiments, the ring is fully welded to the screw. In one or more embodiments, the other end of the screw is smooth. In one or more embodiments, the washer is welded to the first nut. The utility model provides a safety belt tying and hanging device, wherein a circular ring capable of tying and hanging a safety belt is arranged at one end of a screw, a rotatable steel plate and a hollow groove for connecting the steel plate are arranged at the other end of the screw, the flat steel plate can be contained in the hollow groove, when the safety belt tying and hanging device is required to be used, the screw firstly passes through a bolt hole on a wall, after passing through the bolt hole, the steel plate is transversely fixed on the wall, then a first nut is twisted, the screw is integrally fastened, a constructor can tie and hang the safety belt on the circular ring at the moment, the safety belt tying and hanging device is convenient to operate, the installation can be realized by utilizing the existing bolt hole, the safety belt can be conveniently taken out and placed when required, and the repeated utilization of the screw is realized.
