Technical Field

[0001] The utility model relates to the technical field of grounding flat iron angle processing, in particular to a manual bending tool for flat iron. Background Art

[0002] The grounding flat iron is a kind of steel used for lightning protection and grounding. It is generally galvanized or copper-plated and has good anti-corrosion and anti-rust functions. It is often used as a conductor for lightning protection and grounding. The grounding flat iron is usually thinner. During the construction process, in order to improve the reliability of the grounding flat iron, it is often necessary to bend the grounding flat iron, so bending tooling is required for processing.

[0003] At present, when the existing bending tool is used to bend the grounding flat iron, the surface of the bending tool is too rough, which will increase the friction, thereby damaging the surface of the grounding flat iron, and then accelerate the corrosion rate of the grounding flat iron as a whole, affecting the service life. In addition, the bending angle cannot be accurately controlled according to the needs during bending, resulting in cumbersome operation;

[0004] To this end, this case proposes a flat iron manual bending tool to solve the above technical problems. Utility Model Content

[0012] As a further solution of the utility model, the handle and the rotating push rod are both made of threaded steel bars, and the threaded steel bars are symmetrically fixedly connected between the handle and the first bearing to form a triangle.

[0013] As a further solution of the utility model, the angle between the handle and the rotating push rod is set to 175°, the inner diameter of the first bearing is 60 mm, and the outer diameter of the steel pipe is 60 mm.

[0014] The beneficial effects of the utility model are as follows:

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a manual flat iron bending tool comprises a channel steel 1, a steel pipe 2 is fixedly connected to the top of the channel steel 1, a notch groove 3 is symmetrically opened on the steel pipe 2, a first bearing 4 is fixedly connected to the lower part of the outer wall of the steel pipe 2 corresponding to the notch groove 3, a handle 5 is fixedly connected to the outer ring of the first bearing 4, a rotating push rod 6 is fixedly connected to the other side of the outer ring of the first bearing 4, and a plurality of second bearings 7 are fixedly connected to the outer wall of the rotating push rod 6;

[0025] By using on-site production waste and simple combination, the whole set of tools can be completed. This set of tools can accurately and quickly complete the on-site grounding flat iron angle processing, and the tool effectively reduces labor costs and improves construction efficiency. The waste materials on the construction site are used during production, and the processing quality of the grounding flat iron bending angle is guaranteed. The tools can be recycled and reused, and are easy to carry, reflecting the concept of sustainable development.

[0026] In this embodiment, a fixing ring 8 is fixedly connected to the outer side of the steel pipe 2 at the top of the channel steel 1, an annular groove 9 is provided at the top of the fixing ring 8, and an angle line is provided on the inner side of the annular groove 9 corresponding to the top of the fixing ring 8. The angle used for bending can be determined by observing the angle line, thereby facilitating adjustment of the angle, so that the angle of the grounding flat iron can be adjusted as needed.

[0027] In this embodiment, an arc-shaped slider 10 is slidably connected to the inner wall of the annular groove 9 , and a distance is set between the bottom end of the arc-shaped slider 10 and the bottom end of the annular groove 9 , and the remaining distance facilitates the sliding processing of the arc-shaped slider 10 .

[0028] In this embodiment, the thread on the arc-shaped slider 10 passes through the limiting bolt 11, and the bottom end of the limiting bolt 11 is set to be conical. The conical setting facilitates the limiting bolt 11 to be inserted into the bottom end of the annular groove 9, thereby preventing the arc-shaped slider 10 from deflecting.

[0029] In this embodiment, a first stopper 12 is fixedly connected to one side of the limit bolt 11 at the top of the arc-shaped slider 10, and a second stopper 13 is fixedly connected to the bottom end of the handle 5. Through the cooperation of the first stopper 12 and the second stopper 13, there is no need to deliberately control the bending angle during bending, thereby making the operation convenient.

[0030] In this embodiment, the handle 5 and the rotating push rod 6 are both made of threaded steel bars. The threaded steel bars are symmetrically fixedly connected between the handle 5 and the first bearing 4 to form a triangle. Since the triangle is stable, the strength of the handle 5 can be increased. The angle between the handle 5 and the rotating push rod 6 is set to 175°, the inner diameter of the first bearing 4 is 60 mm, and the outer diameter of the steel pipe 2 is 60 mm.

[0031] It should be noted that the utility model is a manual bending tool for flat iron. When in use, the flat iron is first placed in the notch groove 3, and then the handle 5 is pulled to rotate the outer ring of the first bearing 4, thereby rotating the rotating push rod 6. When the second bearing 7 contacts the flat iron, its outer ring will rotate, thereby reducing the friction when contacting the flat iron, thereby reducing the damage to the surface of the flat iron, and thus slowing down the corrosion rate of the surface of the flat iron.

[0032] And when bending, the arc-shaped slider 10 can be moved to a suitable angle, and then the limit bolt 11 is rotated and the bottom end of the limit bolt 11 is inserted into the bottom end of the annular groove 9, thereby completing the limiting fixation of the arc-shaped slider 10. When the handle 5 is rotated, the second stop block 13 will contact the first stop block 12 and limit the second stop block 13. Therefore, the angle can be adjusted according to the bending needs, thereby expanding the scope of application, and there is no need to deliberately control the bending angle during bending, thereby making the operation convenient.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
