[0002] The grounding rod is an auxiliary tool that is often used in the process of power construction. The application of the grounding rod can greatly reduce the risk of electric shock to operators. The existing grounding rod structures are roughly divided into two types. One is to manually rotate the built-in screw to drive the bottom plate to move toward the top plate, thereby clamping the cable; the other is to introduce a motor and use the motor as a power instead of manually driving the screw to rotate, so as to drive the bottom plate to move toward the top plate, thereby clamping the cable. Before clamping the cable, a certain distance needs to be left between the bottom plate and the top plate, and the cable is clamped in it. With the structure one, the operator needs to hold the insulating rod with one hand and turn the screw with the other hand through the handle and other components. When the distance between the top plate and the bottom plate is large, it takes a long time to turn, and this method cannot achieve one-handed operation; while the structure two method can achieve one-handed operation, but the introduction of electrical components increases the cost of the grounding rod.

DETAILED DESCRIPTION

[0023] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] See also Figures 1 to 5 The present invention provides a novel portable grounding operating rod, comprising an insulating rod 1, a top plate 2, a bottom plate 3, a first sliding rod 4 and a second sliding rod 5, wherein the first sliding rod 4 and the second sliding rod 5 are respectively connected to the inside of the insulating rod 1 for sliding up and down movement, the first sliding rod 4 is located on the left side of the inside of the insulating rod 1, and the second sliding rod 5 is located on the right side of the inside of the insulating rod 1, the top end of the first sliding rod 4 is connected to the top plate 2, and the top end of the second sliding rod 5 is connected to the bottom plate 3, and a linkage component is also provided in the insulating rod 1, and the linkage component drives the first sliding rod 4 and the second sliding rod 5 to move in the same direction, and the movement speed of the second sliding rod 5 is greater than the movement speed of the first sliding rod 4.

[0026] Hook the top plate 2 on the cable, pull down the insulating rod 1, and the first slide bar 4 slides upward. The movement of the first slide bar 4 drives the linkage assembly to move, and the second slide bar 5 slides upward through the linkage assembly, and the speed at which the second slide bar 5 slides out is greater than the speed at which the first slide bar 4 slides out, so that the bottom plate 3 can move toward the side of the top plate 2. After pulling down the insulating rod 1 to a certain distance, the bottom plate 3 will contact the bottom of the cable, and the cable will be clamped and squeezed through the top plate 2 and the bottom. The operating rod can firmly bite on the cable to achieve grounding of the cable. This device uses a mechanical connection method and does not introduce electrical components. When clamping the cable, you only need to pull down the insulating rod 1 with one hand to drive the bottom plate 3 to move toward the top plate 2, which greatly reduces the difficulty of operation and improves the operation speed.

[0027] A first vertical slide rail 6 and a second vertical slide rail 7 are provided inside the insulating rod 1 . The first slide bar 4 is slidably installed in the first slide rail 6 , and the second slide bar 5 is slidably installed in the second slide rail 7 .

[0028] The linkage assembly includes a first gear 8, a second gear 9, a speed-up gear 81 and a driven wheel 91. The first gear 8 and the second gear 9 are rotatably connected to the inner wall of the insulating rod 1. The first slide bar 4 and the second slide bar 5 are provided with a rack 10 on the opposite sides. The first slide bar 4 is meshed with the first gear 8 through the rack 10, and the second slide bar 5 is meshed with the second gear 9 through the rack 10. The speed-up gear 81 is coaxially connected to the first gear 8, and the driven wheel 91 is coaxially connected to the second gear 9. The outer diameter of the speed-up gear 81 is larger than the outer diameter of the first gear 8, and the outer diameter of the driven wheel 91 is less than or equal to the outer diameter of the second gear 9. The speed-up gear 81 is meshed with the driven wheel 91.

[0029] After hooking the top plate 2 on the cable, pull the insulating rod 1 downward with one hand, and the first slide bar 4 drives the top plate 2 to slide upward. Under the action of the rack 10 of the first slide bar 4, the first gear 8 drives the speed-up gear 81 to rotate clockwise, and the speed-up gear 81 drives the driven wheel 91 and the second gear 9 to rotate counterclockwise. The second gear 9 pushes the second slide bar 5 to slide upward through the rack 10. The first gear 8 and the speed gear 81 are coaxially connected, so the angular velocity is the same. Therefore, the linear velocity of the speed-up gear 81 with a larger outer diameter is greater than the linear velocity of the first gear 8 with a smaller outer diameter. The speed-up gear 81 is meshed with the driven wheel 91, so the linear velocity of the two is the same. Therefore, the linear velocity of the second gear 9 is also greater than the linear velocity of the first gear 8. Therefore, the sliding speed of the second slide bar 5 is greater than the sliding speed of the first slide bar 4, thereby reducing the distance between the bottom plate 3 and the top plate 2, and finally achieving the clamping of the bottom plate 3 and the top plate 2 on the cable. In addition, the weight of the insulating rod 1 is set to be greater than the weight of the first slide bar 4 and the second slide bar 5. When the top plate 2 and the bottom plate 3 complete the clamping of the cable, the insulating rod 1 always tends to move downward under the action of gravity, thereby exerting an upward force on the second slide bar 5, making the bite of the cable tighter.

[0030] The insulating rod 1 is also provided with a ratchet 11 and a pawl 12 for preventing the first slide bar 4 or the second slide bar 5 from sliding downward. The ratchet 11 is rotatably connected to the inner wall of the insulating rod 1, and the ratchet 11 is coaxially connected to the first gear 8 or the second gear 9. In this scheme, the ratchet 11 is coaxially connected to the first gear 8, and the ratchet 11 and the speed-up gear 81 are arranged on both sides of the first gear 8 one after the other. The pawl 12 is arranged above the ratchet 11, and the inner wall of the insulating rod 1 is provided with a guide platform 13, and a slideway is opened in the guide platform 13. The pawl 12 is penetrated in the slideway and slidably connected to the slideway. The outer wall of the insulating rod 1 is also provided with a reset component.

[0031] When the first slide bar 4 extends outward and the first gear 8 rotates clockwise, the pawl 12 will slide back and forth, and the movements of the first gear 8 and the second gear 9 will not be affected; when the first slide bar 4 slides down and falls back, the first gear 8 will rotate counterclockwise. At this time, the guide platform 13 will cooperate with the pawl 12 to be stuck between the teeth of the ratchet 11, prohibiting the ratchet 11 from rotating counterclockwise, thereby firmly clamping the cable.

[0032] The reset component includes a manual push block 14, a slide groove 15 is provided on the outer wall of the insulating rod 1, the manual push block 14 is slidably connected to the slide groove 15, a hole groove 16 communicating with the interior of the insulating rod 1 is opened in the slide groove 15, an upper limit plate 17 is provided on the top of the pawl 12, and the manual push block 14 is connected to the upper limit plate 17 through the hole groove 16 via a connecting piece.

[0033] A lower limit plate 18 is disposed at the lower portion of the pawl 12 . A return spring 19 is disposed between the lower limit plate 18 and the guide platform 13 . The return spring 19 is sleeved on the pawl 12 .

[0034] When the grounding rod needs to be removed from the cable, the thumb pushes the manual push block 14 upward, and the manual push block 14 slides upward along the slide slot 15, driving the upper limit plate 17 of the pawl 12 to move upward, the pawl 12 is separated from the ratchet 11, and the first gear 8 and the second gear 9 can rotate freely. At this time, the insulating rod 1 is lifted up again, and the cable will exert a downward force on the bottom plate 3. At the same time, the first slide bar 4 and the second slide bar 5 will also move downward under gravity. Similarly, the downward movement speed of the second slide bar 5 will be greater than the first slide bar 4, thereby expanding the distance between the bottom plate 3 and the top plate 2, so that the grounding rod can be removed from the cable. The reset spring 19 can provide a downward force for the reset of the pawl 12 when the ratchet 11 rotates clockwise; at the same time, after the operator releases the manual push block 14, the elastic force of the reset spring can also drive the pawl 12 and the manual push block 14 to reset downward.

[0035] Embodiment 2

[0036] See also Figure 6 The difference between this embodiment and the first embodiment is that the base plate 3 is connected to the second sliding rod 5 through a fine-tuning component.

[0037] The fine-tuning component includes a rectangular rod 20 and a screw rod 21. A vertical and interconnected rectangular through hole and a cylindrical through hole are provided in the second slide rod 5. The rectangular through hole is located at the upper part of the second slide rod 5, and the cylindrical through hole is located at the lower part of the second slide rod 5. The rectangular rod 20 is slidably connected to the rectangular through hole. The bottom plate 3 is connected to the top of the rectangular rod 20. The inner wall of the cylindrical through hole is provided with an internal thread. The screw rod 21 is threadedly connected to the cylindrical through hole. The top of the screw rod 21 is rotatably connected to the bottom of the rectangular rod 20. The bottom of the screw rod 21 extends out of the bottom of the insulating rod 1. A fine-tuning knob 22 is installed at the bottom of the screw rod 21.

[0038] By rotating the fine-tuning knob 22, the screw rod 21 can be driven to move upward along the cylindrical channel, thereby driving the rectangular rod 20 and the base plate 3 to move upward, thereby making a secondary adjustment to the position of the base plate 3, so that the base plate 3 can better clamp the cable and greatly improve the clamping ability.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
