Abstract

The invention provides a hanging hook. The hanging hook comprises a bomb hook, a triggering propping rod and two telescoping rods, wherein the triggering propping rod penetrates a hanging hook body, and one end of the triggering propping rod is propped to the bomb hook, and the other end of the triggering propping rod is provided with an elastic device; the bomb hook is capable of driving the triggering propping rod to move in the first direction; the triggering propping rod is driven by the elastic device to move in the second direction; the two telescoping rods are connected to the triggering propping rod in a pivoting manner and penetrate the hanging hook body; the triggering propping rod moves in the first direction to drive the two telescoping rods to arrive at a first position; the triggering propping rod can move in the second direction to drive the two telescoping rods to arrive at a second position; when arriving at the first position, the two telescoping rods are vertical tothe triggering propping rod and are propped to the bomb hook; and when arriving at the second position, the two telescoping rods are in preset angles relative to the triggering propping rods.

Description

technical field [0001] The application relates to the field of aviation technology, and specifically provides a suspension hook. Background technique [0002] Helicopter landing gear durability drop test is the way to obtain important supporting data for helicopter take-off and landing service life. The durability test has the characteristics of long cycle and full automation, so it puts forward high requirements for the reliability of test implementation. In the durability test, there are problems such as easy decoupling of the bomb hook when the automatic grabbing hook grabs the hook and lifts the basket, and the hook is easy to fatigue and break. Contents of the invention [0003] In order to solve at least one of the above-mentioned technical problems, the present application provides a hook, including: a bomb hook; a trigger push rod, which passes through the main body of the hook and abuts against the bomb hook at one end, and an elastic device is provided on the oth...
