Technical Field

[0001] This utility model relates to the field of test grounding wire reel technology, and in particular to a portable test grounding wire reel. Background Technology

[0002] The test grounding wire reel is a key tool for ensuring the safety of personnel and equipment during power testing and maintenance operations. It neatly stores multiple strands of high-quality soft copper wire in a lightweight reel, has a quick reeling and unfolding function, and a compact design that makes it easy to carry and deploy on site.

[0003] Existing technologies often have the following drawbacks: When the test grounding coil is moved by pulling the lever, relative rotation often occurs between the coil and the main support. At this time, the wires stored on the coil are prone to loosening, thus reducing the performance of the test grounding coil.

[0004] Therefore, this utility model provides a portable test grounding wire reel. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the inconvenience of flexibly fixing the coil body, and to propose a portable test grounding coil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a portable test grounding reel, comprising a main support, with rollers rotatably connected to both sides of the main support, a pull rod slidably mounted on the back side of the main support, a rotating shaft rotatably connected to the surface of the main support, a reel body fixedly connected to the other end of the rotating shaft, a wire body wound on the surface of the reel body, a branch provided at the end of the wire body, a clip and a cable head respectively fixedly connected to both ends of the branch on the wire body, a locking structure provided on the surface of the main support, the locking structure including several slots opened on the side wall of the rotating shaft, a connecting block fixedly connected to the surface of the main support, an insert frame slidably connected inside the connecting block, the size of the insert frame matching the size of the slots.

[0007] The effects achieved by the above components are as follows: by setting a locking structure, the coil body can be flexibly fixed by the locking mechanism, which facilitates the flexible control of the coil body to twist, avoids the loosening of the coil body, improves the stability of coil winding to a certain extent, and improves the stability of carrying the test grounding coil, thus facilitating the carrying of the test grounding coil.

[0008] Preferably, a spring is fixedly connected between the insert frame and the connecting block.

[0009] The effect achieved by the above components is that the insert frame is inserted into the slot on the side wall of the rotating shaft under the action of the spring, effectively locking the coil body.

[0010] Preferably, the insert frame is a rectangular ring structure.

[0011] The effect achieved by the above components is that the rectangular ring-shaped insert prevents the sliding frame from slipping out of the connecting block.

[0012] Preferably, a pivot pin is fixedly connected to the end side of the insertion frame, a pivot plate is rotatably connected to the side wall of the pivot pin, and a support rod is fixedly connected to the surface of the pivot plate.

[0013] The effect achieved by the above components is as follows: when it is necessary to rotate the reel, first pull out the insert frame located inside the slot. After the support rod moves to the appropriate position, rotate the rotating plate to rotate the support rod to the side of the support frame. At this time, temporary support can be provided for the lifted insert frame, which facilitates the flexible rotation of the reel body.

[0014] Preferably, the surface of the main support is provided with a support structure, the support structure including a reserved groove opened on the surface of the main support, a slide plate slidably connected to the inner wall of the reserved groove, and a plurality of tapered rods fixedly connected to the lower end of the slide plate.

[0018] Preferably, the drive rod and the slide plate are internally rotatably connected.

[0019] The effect achieved by the above components is as follows: since the drive rod is rotatably connected to the slide plate, the rotation of the drive rod will cause the slide plate to slide downward in the reserved groove, and the cone rod fixedly connected to the lower end of the slide plate will descend and penetrate into the muddy ground.

[0020] In summary:

[0021] 1. In this utility model, by setting a locking structure, the coil body is flexibly fixed by the locking mechanism, which facilitates the flexible control of the coil body torsion, avoids the loosening of the coil body, improves the stability of coil winding to a certain extent, and improves the stability of carrying the test grounding coil, thus facilitating the carrying of the test grounding coil.

Detailed Implementation

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a portable test grounding reel, including a main support 1, with rollers 2 rotatably connected to both sides of the main support 1, a pull rod 3 slidably installed on the back side of the main support 1, a rotating shaft 4 rotatably connected to the surface of the main support 1, a reel body 5 fixedly connected to the other end of the rotating shaft 4, a wire body 6 wound on the surface of the reel body 5, a branch provided on the end side of the wire body 6, and a clip 9 and a cable head 10 fixedly connected to the two ends of the branch on the wire body 6, respectively, a locking structure 7 provided on the surface of the main support 1, and a support structure 8 provided on the surface of the main support 1.

[0029] The following section will explain the specific design and function of its locking structure 7 and supporting structure 8.

[0030] Reference Figure 1-2 As shown in this embodiment: the locking structure 7 includes several slots 74 formed on the side wall of the rotating shaft 4. A connecting block 71 is fixedly connected to the surface of the main bracket 1. An insert frame 72 is slidably connected inside the connecting block 71. The size of the insert frame 72 matches the size of the slots 74. By setting the locking structure 7, the coil body 5 is flexibly fixed using a locking method, which facilitates flexible control of the twisting of the coil body 5, avoids the loosening of the coil body 6, and improves the stability of winding the coil body 6 to a certain extent, thus improving the stability of carrying the test grounding coil and facilitating the carrying of the test grounding coil. A spring 73 is fixedly connected between the insert frame 72 and the connecting block 71. Under the action of the spring 73, the insert frame 72 is inserted into the slot 74 on the side wall of the rotating shaft 4, effectively locking the coil body 5. The insert frame 72 is a rectangular ring structure. The rectangular ring structure of the insert frame 72 prevents the sliding frame from slipping out of the connecting block 71. A pivot pin 75 is fixedly connected to the end of the insert frame 72, and a pivot plate 76 is rotatably connected to the side wall of the pivot pin 75. A support rod 77 is fixedly connected to the surface of the pivot plate 76. When it is necessary to rotate the reel, the insert frame 72 located inside the slot 74 is first pulled out. After the support rod 77 moves to the appropriate position, the pivot plate 76 is rotated to rotate the support rod 77 to the side facing the support frame. At this time, temporary support can be provided for the lifted insert frame 72, which facilitates the flexible rotation of the reel body 5.

[0031] Reference Figure 1 and Figure 3-4 As shown, specifically, the support structure 8 includes a reserved groove 81 formed on the surface of the main support 1. A sliding plate 85 is slidably connected to the inner wall of the reserved groove 81, and several tapered rods 84 are fixedly connected to the lower end of the sliding plate 85. The tapered rods 84 are driven into the soil surface, which can improve the stability of the main support 1 when the wire body 6 on the test grounding coil is pulled, and prevent the main support 1 from tipping over. A rectangular block 82 is fixedly connected to the surface of the main support 1, and a drive rod 83 is threadedly connected to the inside of the rectangular block 82. The drive rod 83 facilitates the driving operation of the sliding plate 85 inside the reserved groove 81. The drive rod 83 and the sliding plate 85 are rotatably connected internally. Since the drive rod 83 is rotatably connected to the sliding plate 85, the rotation of the drive rod 83 will drive the sliding plate 85 to slide downward in the reserved groove 81, and the tapered rods 84 fixedly connected to the lower end of the sliding plate 85 will descend and drive into the soil surface.

[0032] Working principle: When the test grounding reel needs to be moved, the user can pull the lever 3 on the back of the main support 1. Since the main support 1 has rollers 2 rotatably connected to both sides, pulling the lever 3 allows the entire device to be easily moved on-site, improving the equipment's mobility and facilitating rapid arrival at the working position. Upon arrival, grounding operations are required. The wire 6 wound on the reel body 5 has branches on its ends. A clip 9 at one end of the branch can be used to clamp the equipment requiring grounding, while the cable head 10 at the other end reliably connects to the grounding terminal, thus constructing a complete grounding path and effectively ensuring the safety of personnel and equipment during power testing and maintenance. When the reel body 5 needs to be fixed, the insertion frame 72, under the action of the spring 73, inserts into the slot 74 on the side wall of the rotating shaft 4, effectively locking the reel body 5 and preventing relative rotation between the reel and the main support 1 during movement, thus preventing the wire from... The loose structure of the reel body 5 ensures orderly storage of the equipment. To rotate the reel body 5, for example during wire winding or unwinding, first pull out the insert frame 72 located inside the slot 74. After the support rod 77 connected to the pivot pin 75 at the end of the insert frame 72 moves to the appropriate position, rotate the rotating plate 76 to rotate the support rod 77 to the side facing the support frame. At this time, the support rod 77 can temporarily support the lifted insert frame 72, making it convenient for workers to flexibly rotate the reel body 5 and achieve smooth winding and unwinding of the wire 6. By setting a locking structure 7, the reel body 5 is flexibly fixed using a locking method, which facilitates flexible control of the twisting of the reel body 5 and avoids the wire 6 on the reel body 5 becoming loose. This improves the stability of winding the wire 6 to a certain extent and enhances the stability of carrying the test grounding reel, thus facilitating the carrying of the test grounding reel.

[0033] To ensure the stability of the device during use, the drive rod 83 inside the rectangular block 82 on the surface of the main support 1 is rotated. Since the drive rod 83 is rotatably connected to the sliding plate 85, the rotation of the drive rod 83 will cause the sliding plate 85 to slide downward in the reserved groove 81. The cone rod 84 fixedly connected to the lower end of the sliding plate 85 will then descend and embed itself into the soil. In this way, when the wire 6 is pulled, the cone rod 84 can enhance the stability of the main support 1 and prevent the main support 1 from tipping over, thus ensuring the reliable operation of the equipment. By setting the support structure 8 and embedding the cone rod 84 into the soil, the stability of the main support 1 when the wire 6 on the test grounding wire reel is improved, and the tipping over of the main support 1 is avoided.
