Example Embodiment
[0037] Example 1:
[0038] Such as Figure 1 to Figure 4 As shown, the present invention provides a hook for ships, including a telescopic mechanism 100, a parallel four-bar mechanism 300, and a deformable rod mechanism 200.
[0039] The telescopic mechanism 100 includes a left telescopic rod 110 and a right telescopic rod 120 arranged symmetrically with the left telescopic rod 110. Specifically, the left telescopic rod 110 includes a left rod body 111 and a left tube body 112 slidably sleeved on the left rod body 111; the right telescopic rod 120 includes a right rod body 121 and slidably sleeved on the right rod body. The right tube 122 on the rod 121.
[0040] The parallel four-bar mechanism 300 is arranged between the left telescopic rod 110 and the right telescopic rod 120.
[0041] The deforming rod mechanism 200 includes a first deforming rod assembly 210 provided at the lower end of the left telescopic rod 110 and a second deforming rod assembly 220 provided at the lower end...
Example Embodiment
[0061] Example 2:
[0062] On the basis of the ship hook of the embodiment, the ship hook of this embodiment includes a two-way shape memory alloy 400 suitable for being controlled by a temperature controller. The two-way shape memory alloy 400 is provided between the first hinge shaft 350 and the second hinge shaft 360. The two-way shape memory alloy 400 is electrically connected to a temperature controller, and the temperature controller controls the deformation of the two-way shape memory alloy 400.
[0063] Specifically, the two-way shape memory alloy 400 after energization is suitable for opening or closing the parallel four-bar mechanism 300, and drives the left tube 112 and the right tube 122 to move up and down on the left rod 111 and the right rod 121, respectively. At the same time, due to the up and down movement of the left tube body 112 and the right tube body 122, the first deforming rod assembly 210 and the second deforming rod assembly 220 are opened or closed.
