Description

Technical Field

[0001] This utility model relates to an insulating rod, and more particularly to an insulating rod for maintenance in electrical engineering. Background Technology

[0002] An insulating rod is an auxiliary tool used in live-line work. An insulating rod mainly consists of three parts: a working head, an insulating rod, and a handle. It is mainly used as an insulating tool for convenient operation of high and low voltage live equipment, such as connecting or disconnecting high voltage disconnect switches and drop-out fuses. It is widely used in the power industry and power departments of factories and mines.

[0003] Chinese patent CN212143557U discloses an insulating rod. This utility model's insulating rod is relatively easy to use. Users can hold the handle to make the insulating rod stand upright, and then hold the rod body with their other hand. The hand holding the handle can open the clamping component by pulling the trigger, allowing the clamping component to clamp the debris on the cable and remove it from the cable. This makes it easier and more convenient to remove debris from the cable, reducing the difficulty of operating the insulating rod.

[0004] However, the above-mentioned patent will also have the following problems in use: In order to facilitate the operation of the clamping components by the staff, the insulating rod is of a fixed length and the length of the insulating rod cannot be changed. However, when facing electrical equipment of different heights, the staff need to replace the insulating rod with one of different lengths or raise the staff's height. If the staff carries various insulating rods of different lengths, it will increase the workload of the staff. Raising the staff's height may also increase the danger of the operation, thus making it inconvenient for the staff to inspect and maintain the electrical equipment. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the existing insulating rods are set to a fixed length in order to facilitate the use of clamping components. However, when facing electrical equipment of different heights, the length of the insulating rod cannot be changed, which will cause inconvenience to the staff.

[0006] To address the aforementioned problems, this utility model provides an insulating rod for electrical engineering maintenance, comprising an insulating rod body, a receiving tube, and an extension rod located within the receiving tube. The outer surface of the extension rod has multiple limiting grooves. The outer surface of the receiving tube has an adjusting groove. An adjusting sleeve is rotatably fitted onto the outer surface of the receiving tube. A retaining plate is fixedly connected to the inner wall of the adjusting sleeve. The end of the retaining plate away from the adjusting sleeve movably passes through the adjusting groove and an adjacent limiting groove. A positioning block is fixedly connected to the upper end of the receiving tube. The upper end of the extension rod movably passes through the positioning block and is fixedly connected to a top. A positioning plate is fixedly fitted onto the outer surface of the rod and the top rod. An installation plate is provided at the upper end of the positioning plate. Two clamping plates are provided at the upper end of the installation plate. The installation plate and the two clamping plates are movably fitted onto the outer surface of the top rod. The lower clamping plate is fixedly connected to the installation plate. A compression spring is fixedly connected between the two clamping plates. A pull rod is fixedly connected to the lower end of the upper clamping plate. The lower end of the pull rod movably passes through the compression spring and the lower clamping plate. A screw is internally threaded onto the pull rod. An adjusting rod is fixedly connected to the lower end of the screw. A handle is rotatably connected to the lower end of the adjusting rod. A handle is fixedly connected to the lower end of the receiving tube.

[0007] In the aforementioned electrical engineering maintenance insulating rod, the extension rod can be fixed and adjusted by rotating the clamping plate without hindering the clamping of debris, thereby extending the length of the insulating rod body. At the same time, the length between the handle and the grip can be adjusted by rotating the adjusting rod, which does not hinder the use of the operator and can also adjust the length of the insulating rod.

[0008] As a further improvement of this application, the angle of the adjustment groove is 180 degrees, the middle part of the extension rod is cut, and the depth of the cut is not less than the depth of the limiting groove.

[0009] As a further improvement of this application, the height of the card plate is consistent with the depth of the limiting groove, a gap is left between the longitudinal surface of the extension rod and the inner wall of the receiving tube, and the length of the card plate is less than the depth of the limiting groove and the width of the gap.

[0010] As a further improvement of this application, both the grip and the handle are U-shaped, with the grip positioned above the handle.

[0011] As another improvement of this application, the upper end of the positioning plate is chiseled with multiple limiting holes, and the lower end of the mounting plate is fixedly connected with multiple insert rods corresponding to the multiple limiting holes. The lower end of the insert rods movably passes through the adjacent limiting holes, and the surfaces of both the positioning plate and the mounting plate are chiseled with movable slots corresponding to the pull rods.

[0012] As another improvement of this application, the upper end of the push rod is threaded with a positioning bolt, and the diameter of the upper end of the positioning bolt is larger than the diameter of the push rod.

[0013] In summary, in practical applications, the adjusting sleeve can be rotated counterclockwise to make the clamping plate rotate counterclockwise around the center of the receiving tube until the clamping plate disengages from the limiting groove. Then, the extension rod can be pulled upwards to expose an appropriate length. Then, the adjusting sleeve can be rotated clockwise to make the clamping plate engage with the adjacent limiting groove, thereby limiting and fixing the extension rod. The overall length of the insulating rod can be adjusted. The operator can hold the handle and grip with one hand and adjust the distance between the two clamping plates by pressing the grip, which facilitates the cleaning of debris on electrical equipment. This does not hinder the operator's use and allows for adjustment of the length of the insulating rod. Attached Figure Description

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1 , Figure 2 and Figure 3The following is illustrated: An insulating rod for electrical engineering maintenance includes an insulating rod body, which comprises a receiving tube 1 and an extension rod 2 located within the receiving tube 1. The receiving tube 1 is made of transparent material to facilitate the alignment of the limiting groove 3 and the clamping plate 5 when adjusting the length. Multiple limiting grooves 3 are chiseled on the outer surface of the extension rod 2. An adjustment groove 19 is chiseled on the outer surface of the receiving tube 1. The angle of the adjustment groove 19 is 180 degrees to facilitate the rotation of the clamping plate 5. The middle part of the extension rod 2 is cut with a depth not less than the depth of the limiting groove 3, ensuring that the cut surface does not contact the clamping plate 5, facilitating the rotation of the adjusting sleeve 4, and effectively preventing the extension rod from extending further. Rod 2 disengages from receiving tube 1. An adjusting sleeve 4 is rotatably fitted onto the outer surface of receiving tube 1. A clamping plate 5 is fixedly connected to the inner wall of the adjusting sleeve 4. The end of the clamping plate 5 away from the adjusting sleeve 4 movably passes through the adjusting groove 19 and the adjacent limiting groove 3. The height of the clamping plate 5 is consistent with the depth of the limiting groove 3. A gap is left between the longitudinal surface of the extension rod 2 and the inner wall of the receiving tube 1. The length of the clamping plate 5 is less than the depth of the limiting groove 3 and the width of the gap, so that the clamping plate 5 does not hinder the movement of the extension rod 2 after rotation. A positioning block 6 is fixedly connected to the upper end of the receiving tube 1. The upper end of the extension rod 2 movably passes through the positioning block 6 and is fixedly connected to a top rod 7.

[0026] Figure 2 , Figure 4 , Figure 5 and Figure 6The diagram shows: A positioning plate 8 is fixedly sleeved on the outer surface of the top rod 7. A mounting plate 9 is located at the upper end of the positioning plate 8. Two clamping plates 10 are located at the upper end of the mounting plate 9. Both the mounting plate 9 and the two clamping plates 10 are movably sleeved on the outer surface of the top rod 7. The lower clamping plate 10 is fixedly connected to the mounting plate 9. A compression spring 11 is fixedly connected between the two clamping plates 10. A pull rod 12 is fixedly connected to the lower end of the upper clamping plate 10. The lower end of the pull rod 12 movably passes through the compression spring 11 and the lower clamping plate 10. A screw 13 is internally threaded onto the pull rod 12. An adjusting rod 14 is fixedly connected to the lower end of the screw 13. A handle 15 is rotatably connected to the lower end of the adjusting rod 14. When adjusting the length between the handle 15 and the handle 16, the adjusting rod 14 can be rotated, causing the screw 13 to unscrew, thereby moving the handle 15 up and down. A handle 1 is fixedly connected to the lower end of the receiving tube 1. 6. Both the handle 15 and the grip 16 are U-shaped, with the handle 15 positioned above the grip 16. Workers can hold both the handle 15 and the grip 16 simultaneously. When the fingers press down on the handle 15, the pull rod 12 and the adjusting rod 14 move downwards. At this time, the compression spring 11 deforms downwards under force, causing the upper clamping plate 10 to move downwards, thereby clamping external debris. The upper end of the positioning plate 8 has multiple limiting holes. The lower end of the mounting plate 9 is fixedly connected to multiple insertion rods 17, each corresponding to one of the limiting holes. The lower ends of the insertion rods 17 movably pass through adjacent limiting holes. The surfaces of both the positioning plate 8 and the mounting plate 9 have movable slots corresponding to the pull rod 12. When installing the clamping plate 10, the clamping plate 10 is inserted into the top rod 7, causing the multiple insertion rods 17 to insert into their corresponding limiting holes, thus installing the clamping plate 10 and facilitating its carrying by workers.

[0027] When cleaning debris from electrical equipment using the insulating rod body, the adjusting sleeve 4 can be rotated counterclockwise first, causing the clamping plate 5 to rotate counterclockwise around the center of the receiving tube 1 until the clamping plate 5 disengages from the limiting groove 3 and reaches the cut surface. Then, the extension rod 2 can be pulled upwards to expose an appropriate length. Then, the adjusting sleeve 4 can be rotated clockwise to make the clamping plate 5 engage with the adjacent limiting groove 3, thereby limiting and fixing the extension rod 2. To adjust the overall length of the insulating rod, the operator can hold the handle 16 and grip 15 with one hand and adjust the distance between the two clamping plates 10 by pressing the grip 15, which facilitates cleaning debris from electrical equipment without hindering the operator's use and allows for adjustment of the length of the insulating rod.

[0028] Second implementation method:

[0029] This embodiment adds a positioning bolt 18 to the first embodiment, while the rest remains the same as the first embodiment.

[0030] Figure 7As shown: The upper end of the push rod 7 is threaded with a positioning bolt 18, and the diameter of the upper end of the positioning bolt 18 is larger than the diameter of the push rod 7.

[0031] After installing the clamping plate 10, the positioning bolt 18 can be screwed into the upper end of the top rod 7 to limit the clamping plate 10 above, effectively preventing the clamping parts such as the clamping plate 10 from shaking or falling off during use, thereby effectively improving the stability of the insulating rod body during use.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
