The technical contents and the detailed description of the present invention will be described below with reference to the accompanying drawings:

referring to fig. 1-5, the hook structure of the first embodiment of the present invention is shown in exploded, three-dimensional, front-looking, side-looking and side-sectional views. As shown in the figure: the utility model discloses get in touch the structure, should get in touch the structure and include a ring hook body 1 and a lock rod mechanism 2.

The ring hook body 1 has a handle 11, two ends of the handle 11 extend to form two

curved portions

12, 13, and the two

curved portions

12, 13 extend to form a pivot shaft 14 and a latch portion 15. The pivot shaft 14 has a pivot hole 141, and the pivot portion facing the handle 11 has an inclined surface 142. The latch portion 15 has a recess 151. Wherein, on the inclined side where the two bending

portions

12, 13 and the handle 11 are not parallel to each other, the locking lever mechanism 2 pivoted by the pivot shaft 14 and the latch portion 15 is not parallel to the handle 11. If the handle 11 is taken as the vertical central line a and the two

bending portions

12 and 13 are oblique lines B, the oblique lines B of the two

bending portions

12 and 13 form an included angle θ of 10 ° to 30 ° with the vertical central line a of the handle 11, and the larger the diameter of the handle 11 is, the larger the oblique included angle is, the more preferred the angle is 15 °. In the drawing, the ring hook 1 is an O-shaped body.

The locking lever mechanism 2 includes a fixing lever 21, a torsion spring 22, a lock cylinder 23, a reset component 24 and a shaft 25. One end of the fixing rod 21 is contracted inward to form a through part 211 for sleeving the torsion spring 22, the other end is provided with a clamping groove 212 clamped with the clamping bolt part 15, the inner wall surface of the clamping groove 212 is provided with a clamping tenon 215, the clamping tenon 215 is clamped in the groove 151 of the clamping bolt part 15, the through part 211 is provided with a pivot joint part 213, the shaft rod 25 passes through the pivot joint hole 141 of the pivot joint shaft 14 to be pivoted with the pivot joint part 213, the fixing rod 21 is internally provided with an accommodating space 214, and the accommodating space 214 is used for accommodating the reset component 24. In addition, a fixing hole (not shown) is disposed on an edge surface of the penetrating portion 211, a positioning hole (not shown) is disposed inside the lock cylinder 23, when the torsion spring 22 is sleeved on the penetrating portion 211, one end of the torsion spring 22 is bent and vertically inserted into the fixing hole, the other end of the torsion spring 22 is positioned in the positioning hole of the lock cylinder 23, the torsion spring 22 is fixed outside the penetrating portion 211, the lock cylinder 23 is rotatably sleeved outside the fixing rod 21 and the torsion spring 22, and when the lock cylinder 23 is rotated, the torsion spring 22 provides a rotary reset force for the lock cylinder 23. Furthermore, the lock cylinder 23 has a notch 231, and after the notch 231 of the lock cylinder 23 corresponds to the engaging slot 212, the lock rod mechanism 2 can be pushed inward. The reset component 24 is composed of a spring 241 and a reset spring 242, and is configured in the accommodating space 214 of the fixing rod 21, one end of the reset spring 242 is sleeved with the spring 241, and the other end is configured on the inclined surface 142 of the pivot shaft 14, when the locking rod mechanism 2 is pushed, the reset component 24 enables the locking rod mechanism 2 to automatically reset to the original position.

Referring to fig. 6-8, the operation diagrams of the hook structure of the present invention are shown in one to three. As shown in the figure, the locking cylinder 23 is rotated to correspond the notch 232 on the locking cylinder 23 to the snap groove 212, so as to push the locking rod mechanism 2 inwards. When the two

bent portions

12, 13 are inclined at an angle θ of 10 ° -30 ° relative to the handle 11, and the locking mechanism 2 is inclined relative to the handle 11 after the locking mechanism 2 is pushed away, the opening 16 of the hook body 1 is enlarged, and a rope or other retaining ring is easily inserted into and removed from the hooking space in the hook body 1 after the opening 16 is enlarged.

When the locking rod mechanism 2 is released after the rope (not shown) or the buckle (not shown) enters the loop body 1, the elastic force of the returning elastic piece 242 of the reset component 24 automatically returns the fixing rod 21 to the latch portion 15, so that the latching groove 212 of the fixing rod 21 is latched to the latch portion 15.

After the fixing rod 21 returns to the original position, the torsion spring 22 makes the lock cylinder 23 rotate to return, so that the fixing rod 21 can be locked when the notch 231 of the lock cylinder 23 does not correspond to the snap-in groove 212, and the locking rod mechanism 2 is not pushed away.

Therefore, the two

bent portions

12 and 13 are designed on the non-parallel and non-corresponding inclined sides of the handle 11, so that the opening 16 is enlarged after the locking rod mechanism 2 of the hook structure is pushed away in an inclined manner, thereby facilitating the passing in and out of a rope or other retaining rings, and reducing the design of hook structures with different sizes.

Please refer to fig. 9, a diagram of a hook structure according to a second embodiment of the present invention.
