Abstract

The invention relates to structural design of fasteners, in particular to a pin. The pin comprises a cylindrical pin body, a first installing hole formed in the end portion of the first end of the pinbody, a second installing hole formed in the end portion of the first end of the pin body, and located on the side, backing onto the first end, of the first installing hole, an elastic pulling ring provided with an open end, and a spring rod, wherein the elastic pulling ring is detachably arranged in the first installing hole through the open end; the spring rod comprises a fixed end, an extending portion and a hook end which are sequentially connected; the fixed end is fixedly arranged in the second installing hole; the extending portion extends to the second end of the pin body in the length direction of the pin body; and a hook matched with the second end of the pin body is formed at the hook end. The pin is simple in structure and convenient to operate; and due to the fact that the locking insurance is performed at the hook end of the spring rod, the locking function is reliable.

Description

technical field [0001] The invention relates to the structural design of fasteners, in particular to a pin. Background technique [0002] In aircraft structural design, many moving parts are pinned in both open and closed positions. However, most of the existing pins have disadvantages such as complex structure or unreliable locking safety due to the principle of locking safety. Contents of the invention [0003] The object of the present invention is to provide a pin to solve at least one problem existing in the use of existing pins. [0004] Technical scheme of the present invention is: [0005] A pin comprising: [0006] The pin body is cylindrical and has opposite first and second ends; [0007] The first installation hole is opened at the first end of the pin body along the axis direction perpendicular to the pin body; [0008] The second mounting hole is opened at the first end of the pin body in a direction perpendicular to the axis of the pin body, and is loca...
