[0027] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0028] In this article, "schematic" means "serving as an example, instance or illustration", and any diagram or implementation described as "schematic" in this article should not be interpreted as a more preferred or more advantageous technical solution. In order to make the drawings concise, each figure only schematically shows the parts related to the exemplary embodiment, and they do not represent the actual structure and true proportion of the product.

[0029] A high-strength hook in the present invention can be installed on the rod body 90. Figures 1 to 3 As shown, the high-strength hook includes: a hook body 10, a pressing member 20 and a swing bolt 30.

[0030] like Figures 1 to 3 As shown, the hook body 10 has a curved path 11. The hook body 10 has an inner end 12 along the curved path 11. The inner end 12 can abut against a portion of the outer circumferential surface of the rod body 90. The inner end 12 has an inner end extension direction 13 that can be parallel to the extension direction of the rod body 90. The hook body 10 has a bottom end 41 and a top end 42 along the curved path 11.

[0031] like Figures 1 to 3As shown, the pressing member 20 is rotatably connected to the bottom end 41 along a rotation axis 21. The rotation axis 21 is parallel to the inner end extension direction 13. The pressing member 20 can rotate around the rotation axis 21 toward the top end 42 to a pressing position 23. The pressing member 20 forms a through slot 22 perpendicular to the extension direction of the rod body 90 at a position near the top end 42. The through slot 22 forms a notch in the direction away from the hook body 10.

[0032] like Figures 1 to 3 As shown, the hinge component, i.e., the hinge bolt 30, has a connecting end 31 and a locking end 32 along its extending direction. The connecting end 31 is rotatably connected to the top end 42.

[0033] like Figure 1 As shown, the locking component, i.e., the locking nut 50, is disposed at the buckling end 32 and located at the end of the through slot 22 away from the hook body 10. The buckling end 32 is provided with an external thread, so that the locking nut 50 can move along the extension direction of the swing bolt and can drive the pressing member 20 to be located at the pressing position 23, so that the inner end 12 and the pressing member 20 can abut against the outside of the rod body 90.

[0034] The high-strength hook of the present invention is used during use. Figure 2 As shown, the lamp 80 is fixed to the bottom end 41 of the clamping member 20. The hook body 10 is hung on the rod body 90 (90 is a part of the fixed beam or fixed member). At this time, the hook body 10 can be independently hung on the rod body 90, which is convenient for the subsequent fixation of the installer. The clamping member 20 is rotated from A1, A2 to A3 in sequence along the rotation direction A in the figure, and the clamping member 20 is rotated to the clamping position 23.

[0035] like Figure 3 As shown, the buckling end 32 of the swing bolt 30 is rotated along the rotation direction B. The buckling end 32 is placed in the through slot 22, and the locking nut 50 is rotated so that it can move along the extension direction of the swing bolt and drive the pressing member 20 to be located at the pressing position 23, so that the inner end 12 and the pressing member 20 can abut against the outside of the rod body 90.

[0036] It can be seen that the high-strength hook of the present invention is easy to install. The hook body is directly connected to the lamp 80 and is an integrated design, which effectively ensures the overall strength of the connection structure. By adjusting the locking nut 50, the high-strength hook of the present invention can be suitable for rods of different diameters and suitable for various installation conditions.

[0037] like Figures 1 to 3As shown, in another embodiment of the high-strength hook of the present invention, the inner end 12 is an inner surface. The inner surface is an arc-shaped surface and forms a plurality of first tooth grooves 14. The extension direction of the first tooth grooves 14 is parallel to the inner end extension direction 13. Thus, the fixing surface 26 is increased, and the fixing of the rod body can be more stable. Two first side width tooth grooves 15 arranged at a set interval are formed on the inner surface. The bottom of the first side width tooth groove 15 is triangular.

[0038] like Figures 1 to 3 As shown, in another embodiment of the high-strength hook of the present invention, the pressing member 20 includes a pressing surface toward the inner end 12. The pressing surface is an arc-shaped surface and forms a plurality of second tooth grooves 24. The extension direction of the second tooth grooves 24 is parallel to the extension direction 13 of the inner end.

[0039] Thus, when the outer circumference of the rod body 90 is an irregular shape or a square shape, the first tooth grooves 14 and the second tooth grooves 24 can stably fix the outer circumference of the rod body 90 .

[0040] like Figures 1 to 3 As shown, a second side wide tooth groove 25 is formed on the pressing surface. The bottom of the second side wide tooth groove 25 is triangular. When the inner end 12 and the pressing member 20 are against the outside of the rod body 90, the two first side wide tooth grooves 15 and the one second wide tooth groove can be surrounded by three adjacent corners of a square.

[0041] Therefore, when the rod body 90 is a square rod body 91 as shown in the figure, the fixation of the rod body is more stable.

[0042] like Figure 4 As shown, in another embodiment of the high-strength hook of the present invention, it further includes: a hanging object connecting member 60, which forms a hanging hole 61. The hanging object connecting member 60 is integrally formed at the bottom end 41. Thus, it is convenient to install the lamp 80.

[0043] like Figures 1 to 3 As shown, in another embodiment of the high-strength hook of the present invention, one end of the pressing member 20 forming the through slot 22 includes a fixing surface 26. The fixing surface 26 can be perpendicular to the axis of the swing bolt 30, which is more conducive to the fixing of the locking nut.

[0044] In another embodiment of the high-strength hook of the present invention, a limiting convex ridge 27 is formed on the fixing surface 26. The limiting convex ridge 27 is parallel to the inner end extension direction 13. Therefore, it is more conducive to the fixing of the locking nut and the locking nut can be effectively prevented from falling off from the notch through the nut washer.

[0045] In another embodiment of the high-strength hook of the present invention, the locking nut 50 is a butterfly-shaped nut or a straight nut. The butterfly-shaped nut has two parallel rotation surfaces. The rotation surfaces are perpendicular to the axis of the swing bolt 30. This makes it easier to operate the locking nut 50.

[0046] In another embodiment of the high-strength hook of the present invention, a plurality of indentations are formed at intervals on the rotating surface, so that the screwing friction of the locking nut 50 is greater, which facilitates stable operation.

[0047] In another embodiment of the high-strength hook of the present invention, the pressing member 20 is connected to the bottom end 41 through a spherical connecting member, so that the connection of the pressing member is more flexible.

[0048] At the same time, if Figure 5 As shown, the present invention also provides a high-strength lifting structure, which includes: a lifting beam and a high-strength lifting hook of the present invention. The lifting beam has a rod body 90. The high-strength lifting hook is assembled on the rod body 90.
