[0024] like Figure 1-Figure 8 As shown, the present application provides a micro-switch mechanism safety pin structure, including:
[0025] A supporting top shaft 3, a fixed pin handle 2 and a rotating disk 1;
[0026] Among them, the first end of the support top shaft 3 has a top head, the second end is fixedly connected to the rotating disk 1, the support top shaft 3 has a partial external thread, the fixed pin handle 2 is threadedly connected to the support top shaft 3, and the fixed pin handle 2 is detachably connected to the external connection port of the microswitch structure.
[0027] In some optional embodiments, the top of the supporting top shaft 3 is a rotating body structure, and the diameter of the middle part gradually decreases toward the two ends.
[0028] In some optional embodiments, the second end of the top shaft 3 is configured as a prism, and the second end face has an internal threaded hole. The center hole of the rotating disk 1 is sleeved on the prism, and the hexagonal bolt 5 is threadedly connected to the internal threaded hole to fix the rotating disk 1.
[0029] In some optional embodiments, the fixing pin handle 2 has a central hole, and a hexagonal nut connected to the supporting top shaft (3) is provided in the central hole.
[0030] The central hole of the fixing pin handle 2 gradually expands toward the end with the plug to form a conical space for accommodating part of the plug.
[0031] The top shaft 3 is sleeved with a connecting ear piece 4 for tying a rope.
[0032] The fixed pin handle 2 has an axial hook claw, and the outer edge of the external connection port of the micro-switch structure has a limit platform. The hook claw hooks the limit platform at a preset angle, and the limit platform limits the axial bidirectional displacement and circumferential unidirectional rotation freedom of the hook claw. Specifically, the axial hook claw forms a groove on the inside, and the limit platform is placed in the groove. In order to limit the circumferential rotation freedom, the inner diameter of the groove can be set to a gradually decreasing slope so that the groove and the limit platform become tighter and tighter during the circumferential relative rotation, or the groove has a brake platform that contacts and stops with the limit platform to limit the circumferential movement of the groove and the limit platform.
[0033] After the pin handle is fixed to the external connection port of the relevant micro-switch structure, the rotating disk connected to the outer end of the rotating support shaft is rotated to make it move forward, and the force pin of the switch mechanism is pushed to the safe state of the micro-switch structure. The safety insurance function requirements of the relevant micro-switches in the cockpit of the aircraft are met. The rotating disk connected to the outer end of the support shaft is effectively fixed and connected by a hexagonal bolt. The connecting ear can be fixedly connected with the entire set of safety pin equipment.
[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
