It is noted that the drawings are not necessarily to the same scale so as to clearly illustrate the structures of the various elements of the embodiments of the utility model. Like reference numerals are used to denote like parts.

The utility model discloses a temporary fixing device for an overhead cable in a construction site, which is shown in fig. 1 and 2. The temporary fixing device for the construction site overhead cable comprises a fixing plate 10, a buckle wheel 20 and a hook 30, wherein the fixing plate 10 is arranged on a building structure, the hook 30 is arranged on the side surface of the fixing plate 10, the buckle wheel 20 is sleeved on the hook 30, and the overhead cable is arranged on the side surface of the building structure through a groove of the buckle wheel 20.

Further, the hook 30 is formed by bending a reinforcing bar, and includes a connecting section 31, a horizontal section 32, an upright section 33, and a circular arc section 34, which are integrally formed, and as shown in fig. 3, a flat surface 30a is disposed on an outer circumferential side of the connecting section 31, and the hook 30 is welded to a side surface of the fixing plate 10 through the flat surface 30a.

Further, the buckle wheel 20 is sleeved on the horizontal section 32, the length of the horizontal section 32 is matched with that of the buckle wheel 20, and the circular arc section 34 extends from the end of the vertical section 33 to the circular arc of the connecting section 31. The arrangement of the circular arc section 34 can effectively prevent the cable from jumping excessively and separating from the space limited by the hook 30 in the moving process, and the stability of cable transmission is ensured.

It will be appreciated that the securing of the hook 30 and the catch wheel 20 requires attention to the sequence. First, the connecting section 31 at the bent portion of the hook 30 is formed, and then the flat surface 30a is formed on the side surface of the connecting section 31, so that the hook 30 is welded to the side surface of the fixing plate 10 through the flat surface 30a, and then the snap wheel 20 is fitted over the hook 30, and then the hook 30 is bent to form the upright section 33 and the circular section 34.

In one embodiment of the present invention, the click wheel 20 is made of hard plastic, and the through hole 21 is matched with the outer diameter of the hook 30. Preferably, the click wheel 20 is made of teflon. The polytetrafluoroethylene has good insulation, and can prevent the clamping wheel 20 from generating static electricity in the rotating process to influence the safety of cable transmission.

As another embodiment of the present invention, the temporary fixing device further includes a protective cover 40 covering the through hole 21 of the click wheel 20. As shown in fig. 4 and 5.

Furthermore, the number of the protection sleeves 40 is a pair, and the protection sleeves are sleeved at two ends of the buckle wheel 20; the protective cover 40 includes a cylinder 41 and a cover plate 42, which are integrally formed, as shown in fig. 6, the outer diameter of the cylinder 41 matches with the inner diameter of the through hole 21.

In one aspect of the embodiment, the protective sleeve 40 is made of hard rubber, and the wall thickness of the cylinder 41 is not greater than 3 mm. The cover plate 42 is an annular structure, and the outer diameter of the cover plate is not larger than that of the snap wheel 20. The arrangement of the protective sleeve 40 can slow down the abrasion between the buckle wheel 20 and the hook 20, and prolong the service life of the buckle wheel 20.

In order to prevent the circular arc section 34 of the hook 30 from contacting the rotating buckle wheel 20 to interfere with the smooth rotation of the buckle wheel 20, the length of the upright section 33 is greater than the radius of the buckle wheel 20. It is understood that, in some embodiments, the hook 30 may also be composed of a connecting section 31, a horizontal section 32, and a circular section 34, where the circular section 34 is disposed from the end of the horizontal section 32 to the direction of the connecting section 31, and the radian of the circular section 34 is slightly larger to avoid the circular section 34 interfering with the snapping wheel 20.

In the present invention, an insulating sheath 50 is disposed on the outer peripheral side of the hook 30, and as shown in fig. 7, the insulating sheath 50 is made of polyethylene. The insulating sheath layer 50 is disposed on the horizontal section 32 and the vertical section 33 of the hook 30, and the wall thickness thereof is 0.1-0.3 mm. The insulating jacket layer 50 can prevent the hook 30 from being worn too fast, and the service life of the temporary fixing device is prolonged.

Compared with the defects and shortcomings of the prior art, the temporary fixing device for the construction site overhead cable is reasonable in structure and convenient and fast to operate, the cable is fixed on the buckle wheel and rotates along with the buckle wheel, manual dragging is reduced, cable laying time is saved, and working efficiency is improved.

The present invention is not limited to the above embodiments, and any other various products can be obtained by anyone in light of the present invention, but any changes in shape or structure thereof, which have the same or similar technical solutions as the present application, fall within the protection scope of the present invention.
