Detailed Description

The detailed description and technical contents of the present invention will be described below with reference to the drawings, however, the drawings are only for illustrative purposes and are not intended to limit the scope of the present invention.

Fig. 1 to fig. 3 are a schematic perspective view, an exploded perspective view and a cross-sectional view of the safety hook with rollers according to the present invention. The utility model relates to a safety hook 1 with rollers, which comprises a hook body 10, a connecting rod 20, a roller group 30 and a lifting ring swivel mount 40. The connecting rod 20 and the roller set 30 are combined on the hook body 10; the hanging ring swivel mount 40 is coupled to a bottom side of the hook 10 for a rope to be threaded through or another hook to be hung on. The structure of the safety hook with roller 1 will be described in more detail as follows.

The hook body 10 is C-shaped and has an opening 11. The hook body 10 is provided with a pivot portion 12 and a locking portion 13 on opposite sides of the opening 11, and a pair of shaft holes 14 and a joint portion 15 are formed at one end of the hook body 10. Preferably, the hook body 10 is formed as a pair of loop segments 16 at the pair of shaft holes 14.

The connecting rod 20 has a locking portion 21. One end of the connecting rod 20 is connected to the pivot portion 12 so that the locking portion 21 can be locked with the locking portion 13 to close the opening 11.

Further, the roller assembly 30 includes a shaft 31 and a roller 32. The roller 32 is disposed through the shaft 31, and two ends of the shaft 31 are respectively disposed through the pair of shaft holes 14, so that the roller 32 can rotate in the hook 10. Preferably, the roller set 30 further includes a pair of bearings 33. The pair of bearings 33 are correspondingly disposed between each of the shaft holes 14 and the roller 32.

In addition, in the present embodiment, one of the pair of shaft holes 14 is a screw hole 141; the rotation shaft 31 has a screw 311 at one end, and the rotation shaft 31 is fixed to the hook 10 by engaging the screw 311 with the screw hole 141.

In the present embodiment, specifically, the roller 32 tapers from two sides to the middle to form a concave profile 321 on the outer surface. In addition, the joint portion 15 is formed with a protrusion 151 corresponding to the concave contour 321.

The suspension ring swivel mount 40 includes a swivel head 41 and a suspension ring 42 connected to the swivel head 41. The steering head 41 is coupled to the joint portion 15 and is capable of freely rotating, thereby changing the direction of the suspension ring 42. In addition, the rotation shaft 410 of the steering head 41 is perpendicular to and passes through the rotation shaft 320 of the roller 32.

In an embodiment of the present invention, the hook 10 has a screw hole 150 at the joint portion 15. Furthermore, the ring base 40 further includes a screw 43. The ring swivel mount 40 passes through the screw 43 and penetrates the steering head 41 and the screw hole 150 to connect with the joint part 15.

Specifically, the steering head 41 has a through hole 411. In addition, one end of the screw 43 is inserted through the through hole 411 and coupled to the screw hole 150.

More specifically, the hanging ring 42 has an oblong hole 421, and the hanging ring 42 is provided with a circular hole 422 at two sides of the oblong hole 421, so that the outline of the hanging ring 42 is fan-shaped, and the hanging ring swivel base 40 can be held by hand to be combined with the joint part 15 when assembled.

It should be noted that the circular hole 422 can be used for attaching a decoration for identification. In addition, a rope can be inserted into the oblong hole 421, and since the oblong hole 421 is symmetrically disposed corresponding to the rotating shaft 410 of the steering head 41 and the rotating shaft 410 of the steering head 41 is perpendicular to and passes through the rotating shaft 320 of the roller 32, the rope inserted into the oblong hole 421 does not interfere with the rope inserted through the roller 32. In addition, the oval slot 421 can be used to hang another safety hook, and the safety hook hung in the oval slot 421 has better stability and balance effect.

Please refer to fig. 4 and fig. 5, which are two schematic views of the safety hook with rollers according to the present invention. As shown in fig. 4, when the safety hook 1 with a roller of the present invention is used, another safety hook 2 can be hooked in the oval long hole 421 of the hanging ring 42. The suspension ring base 40 is rotatable through the steering head 41. Therefore, the safety hook 2 and its attached object, which are attached to the hanging ring 42, can be turned with the turning head 41.

Referring to fig. 5, when the safety hook 1 with roller of the present invention is in use, a rope 3 (or a steel cable, etc.) can be threaded on the roller 32 of the roller set 30, and the rope 3 can be positioned on the roller 32. Moreover, the safety hook 2 hooked by the hanging ring rotary seat 40 can be hooked with another safety hook 4 with a roller through the rope 3, thereby achieving the purposes of labor saving and steering.

The above description is only for the preferred embodiment of the present invention, and the claimed invention is not limited thereto, and all the modifications that can be easily conceived by those skilled in the art according to the technical contents disclosed in the present invention are within the scope of the present invention.
