Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific examples. However, the uses and purposes of these exemplary embodiments are only used to illustrate the present invention, and do not constitute any form of limitation to the actual protection scope of the present invention, nor limit the protection scope of the present invention thereto.

[0033] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the automatic opening pin includes a pin body 1, a cylinder 2 and a stop pin 3, the inside of the pin body 1 is hollow, the stop pin 3 is located inside the pin body 1, and the cylinder 2 is slidably installed on the pin body 1 Inside, there is a non-return mechanism 4 between the cylinder 2 and the pin body 1. One end of the cylinder 2 extends to the outside of the pin body 1 to form a pressing part, and the other end extends to the inside of the pin body 1 and is connected to the stop pin 3. In contact with each other, the pin...

Abstract

The invention relates to the technical field of fastener structures and provides an open type pin. The open type pin comprises a pin body, a cylinder and a stop pin. The interior of the pin body is hollow. The stop pin is located inside the pin body. The cylinder is slidably mounted in the pin body. A non-return mechanism is arranged between the cylinder and the pin body. One end of the cylinder extends out of the pin body to form a pressing part, and the other end of the cylinder extends into the pin body to make contact with the stop pin. First openings are symmetrically formed with respectto the axis of the side face of the end, close to the stop pin, of the pin body. When external force is applied to the stop pin, the two ends of the stop pin stretch out of the pin body along the first openings. By adoption of the open type pin, the technical problems that after an existing open type pin is inserted into a fastener, open legs of the pin needs to be opened manually, and consequentially, using is inconvenient, and the work efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of fastener structures, in particular to a split pin. Background technique [0002] Pins are connectors used to locate and fasten fasteners, and pins play a pivotal role in the connection of mechanical parts. According to the different shapes and functions, the pins can be divided into: cotter pins, conical pins, cylindrical pins, grooved pins, etc. Among them, cotter pins are widely used in the connection of daily fasteners. For example, cotter pins are widely used in the connection of accessories on the running part of vehicle bogies, and the suspension clamps of wires in power transmission lines. [0003] Taking power transmission lines as an example, cotter pins can prevent fasteners from falling off and are widely used on power transmission lines. But cotter pin also has following defect in the process of using: (1), cotter pin needs pin to be inserted earlier in the process of using, and then the pin...
