Abstract

The invention relates to the technical field of pin shaft structure design, and particularly provides a bearing stop pin shaft for bearing and hinging between a first connecting piece and a second connecting piece. A hollow pin shaft body, a stop piece, a first check ring, a second check ring and a transmission piece are included. The hollow pin shaft body penetrates through the first connecting piece and the second connecting piece. A groove A is formed in one end face of the hollow pin shaft body, and a groove B is formed in the other end face of the hollow pin shaft body. The stop piece sleeves one side of the hollow pin shaft body and coaxially rotates with the hollow pin shaft body. An inner ring of the stop piece is provided with a protruding block A matched with the groove A. A stopboss is arranged on the first connecting piece and drives the stop piece and the first connecting piece to coaxially rotate. The first check ring is fixed to one side of the stop piece, the second check ring is fixed to the other side of the hollow pin shaft body, and the end face of the second check ring is provided with a protruding block B matched with the groove B. The transmission piece penetrates through the hollow pin shaft body, one end of the transmission piece is fixed to the first check ring and coaxially rotates with the first check ring, and the other end of the transmission piece is fixed to the second check ring and coaxially rotates with the second check ring.

Description

technical field [0001] The invention relates to the technical field of pin shaft structure design, in particular to a load-bearing stop pin shaft. Background technique [0002] In aerospace structures, there are many connection parts with large loads and the structural space is tight. A structural design with complete stop function and low weight is required. At the same time, design factors such as reliability, safety, corrosion, and fatigue need to be considered comprehensively. [0003] Conventional stop connection structures with high load-bearing capacity are mainly designed with large connecting pins and stop bolts or stop pins. This design mode has certain disadvantages in terms of structural weight, space and local stress corrosion of threaded parts. Contents of the invention [0004] In order to overcome at least one defect in the above-mentioned prior art, the present invention provides a load-bearing stop pin for carrying and hinged between the first connecting ...
