Description

Connecting ring with overload warning and protecting functions Technical Field The utility model relates to the technical field of locking tools, in particular to a connecting ring with overload warning and protecting functions. Background In various fields of industrial production, hoisting operation, transportation and the like, the connecting ring is used as a key connecting piece and plays an important role in load transmission and connecting parts. Conventional connecting rings generally have only basic connecting functions, and the structural design thereof focuses on ensuring the connection strength and stability under normal working conditions. The existing self-locking connecting ring adopts a mode of automatically locking nuts, hooks and rivets as disclosed in the publication No. CN205387870U, is safe and convenient compared with the common manual lock in the prior art, and has high-strength breaking force of more than 3000KG, but in the actual use process, the connecting ring can face overload conditions exceeding the rated bearing capacity of the connecting ring due to complex and changeable working conditions, and when the connecting ring is overloaded, if the connecting ring lacks effective warning and protecting measures, equipment damage, component falling and even safety accidents are extremely easy to cause, not only serious economic loss, but also life safety of operators can be threatened. Disclosure of utility model The utility model aims to solve the defects that in the prior art, the working condition is complex and changeable, the connecting ring possibly faces overload exceeding the rated bearing capacity of the connecting ring, when the connecting ring is overloaded, if the connecting ring lacks effective warning and protecting measures, equipment damage, component falling and even safety accidents are easily caused, not only serious economic loss is caused, but also life safety of operators is possibly threatened, and the connecting ring with the overload warning and protecting functions is provided. In order to achieve the above purpose, the present utility model adopts the following technical scheme: the utility model provides a go-between with overload warning and protect function, includes go-between body and overload protection mechanism, overload protection mechanism includes the fixed block, the circular slot has been seted up at the top of fixed block, the roller bearing with go-between body swing joint is connected with in the circular slot middle-end rotation, the activity chamber has been seted up to the bottom of fixed block, the activity intracavity is provided with the protection component who cuts off the go-between body, the activity chamber is provided with U type hook through the protection component, the outer wall sliding connection of fixed block has overload warning pole.
