In order to solve the problem encountered in the background art, the application provides a novel quick plug safety pin of integral type, makes this safety pin can realize quick plug on the basis of guaranteeing normal insurance function, improves work efficiency.
As shown in fig. 1 and 2, the integrated quick-plugging safety pin 1 provided by the present application includes a bracelet 12, a connecting rod 11, and a safety elastic part 13.
The inner diameter of the bracelet 12 should be able to pass through the fingers of a normal adult, facilitating forceful pulling. For example, in the present application, the inner diameter of the bracelet 12 is set between Φ 24- Φ 28.
The link 11 constitutes a connection portion between the bracelet 12 and the safety elastic part 13, and preferably, the link 11 has a bent angle structure, so that space can be saved.
The safety elastic part 13 is a main force bearing part of the safety pin, an opening structure is formed by the upper elastic rod 131 and the lower elastic rod 132, the top end distance or the size of the opening part formed by the upper elastic rod 131 and the lower elastic rod 132 is larger than the size of the safety hole by utilizing the elasticity of cold drawing of a steel wire, and after the safety pin 1 penetrates into the safety hole, the over-win matching is realized. The length of the safety elastic part 13 should be no less than the length of the safety hole to play a safety role.
As shown in fig. 3, in the preferred embodiment of the present application, the upper elastic bar 131 includes an upper straight portion 1312 and an upper arc portion 1311 extending outward from the link direction, and the outer surface high point of the upper arc portion 1311 is located at a greater distance from the axis of the safety elastic portion than the upper straight portion 1312.
