[0020] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0021] A lifeboat hook device, as Figures 1 to 3 shown, includes a frame body 1, a hook body 2 is rotatably connected to the frame body 1, the middle part of the hook body 2 is rotatably connected to the frame body 1, a cable stopper 3 is installed on the frame body 1, and the rotation of the hook body 2 can make its hook head approach or move away from the cable stopper 3.

[0022] It should be noted that by rotating the hook body 2 to make its hook head approach the cable stopper 3, the hook body 2 and the cable stopper 3 cooperate to form a limiting area 4 for limiting the rope. The limiting area 4 is in a closed state, thereby restricting the rope from detaching, so as to ensure the stability of the rope. On the contrary, by rotating the hook body 2 to make its hook head move away from the cable stopper 3, the rope can be detached from the limiting area 4.

[0023] A locking block 5 is rotatably connected to the frame body 1, one end of the locking block 5 is rotatably connected to the frame body 1, a limiting groove 6 is opened on the locking block 5, the limiting groove 6 is located in the middle of the locking block 5, and the end of the hook body 2 is inserted into the limiting groove 6, and the limiting groove 6 limits the hook body 2.

[0024] An unlocking block 7 is rotatably arranged on the frame body 1, one end of the unlocking block 7 is rotatably connected to the frame body 1, the other end of the unlocking block 7 is connected with a cable 8, when the cable 8 pulls the unlocking block 7 to rotate, the locking block 5 can rotate and drive the hook body 2 to rotate, so that the hook head of the hook body 2 moves away from the cable stopper 3. As the hook body 2 rotates and moves away from the cable stopper 3, the rope can be detached from the limiting area 4.

[0025] A limiting member for limiting the rotation of the locking block 5 is arranged on the frame body 1. The limiting member includes a camshaft 9. The locking block 5 abuts against the cam side wall of the camshaft 9, so as to support the locking block 5 through the camshaft 9, and further realize the rotation limit of the locking block 5.

[0026] Specifically, a positioning groove 10 is opened on the locking block 5, the positioning groove 10 is located at the other end of the locking block 5, and the inner wall of the positioning groove 10 abuts against the cam side wall of the camshaft 9, so as to ensure the stable support of the camshaft 9 for the locking block 5 and also ensure the stability of the locking block 5.

[0027] The unlocking block 7 is arranged on the camshaft 9, the camshaft 9 is rotatably arranged on the frame body 1, and the rotation of the unlocking block 7 can drive the camshaft 9 to rotate.

[0028] It should be noted that during unhooking, as the unlocking block 7 rotates clockwise under the pulling of the cable 8, the unlocking block 7 drives the camshaft 9 to rotate clockwise. As the camshaft 9 rotates, the cam on the camshaft 9 rotates accordingly. After the locking block 5 loses the support of the cam, under the action of gravity, the locking block 5 rotates clockwise, and the locking block 5 drives the hook body 2 to rotate counterclockwise, so that the hook head of the hook body 2 moves away from the cable stopper 3. At this time, the limiting area 4 is in an open state, and the rope can be detached from the limiting area 4.

[0029] On the contrary, when the hook is locked, after the force on the cable 8 is removed, the unlocking block 7 rotates counterclockwise and resets under the action of the cable 8. It should be noted that the cable 8 belongs to the existing technology, and how to rotate and reset the unlocking block 7 through the elastic restoring force of the cable 8 will not be repeated. The unlocking block 7 drives the camshaft 9 to rotate counterclockwise, and the cam on the camshaft 9 rotates accordingly, so that the cam pushes the locking block 5 to rotate counterclockwise, and the locking block 5 drives the hook body 2 to rotate clockwise, so that the hook head of the hook body 2 is close to the stop block 3, and the hook body 2 cooperates with the stop block 3 to form a limiting area 4. At this time, the limiting area 4 is in a closed state, and the rope cannot detach from the limiting area 4.

[0030] When unhooking, the operator only needs to pull the cable 8, and when locking the hook, the operator only needs to remove the force on the cable 8. The operation of unhooking and locking the hook is simple and easy to use, which can effectively improve efficiency.

[0031] A limiting protrusion 11 is provided on the inner side wall of the limiting groove 6, and the limiting protrusion 11 limits the hook body 2 to prevent the end of the hook body 2 from escaping from the limiting groove 6, thereby ensuring the stability of the cooperation between the two. Moreover, when the locking block 5 rotates clockwise, the limiting protrusion 11 conflicts with the side wall of the hook body 2, thereby driving the hook body 2 to rotate and move away from the stop rope block 3.

[0032] Furthermore, the surface of the limiting protrusion 11 is arc-shaped, which can effectively reduce the wear caused to both the limiting protrusion 11 and the hook body 2 when they conflict with each other, thereby increasing the service life.

[0033] A connection hole 12 is provided on the top of the frame 1, which is connected to the boat sling through the connection hole 12, so that the boat sling bears all the load.

[0034] A lifting ring 13 is installed on the hook body 2, which is convenient for lifting and moving through the lifting ring 13, making transportation more convenient and quick.

[0035] The specific embodiments described in this article are merely examples of the spirit of the present invention; technicians in the technical field of the present invention may make various modifications or additions to the described specific embodiments or replace them in a similar manner, but they will not deviate from the spirit of the present invention or exceed the scope defined by the attached claims.
