Description

Technical Field

[0001] This invention relates to the field of grounding clamp technology, specifically to a power grounding clamp. Background Technology

[0002] The power connection clamp, through a connecting rod, passes the connection end upward to cooperate and fix it with the remaining connection end on the high-voltage line, and connects the connection clamp to the grounding wire, inserting the other end of the wire into the ground. This prevents the equipment from being suddenly powered on and the induced voltage generated by nearby high-voltage equipment from harming the human body, while also discharging the residual charge of the de-energized equipment.

[0003] The invention patent application with application number CN202210775359.0 discloses a power grounding clamp and its grounding device, including a rod body, on which a hook body is provided, and two clamping plates are rotatably disposed inside the hook body. The two clamping plates rotate synchronously and have a first rotation state with opposite rotation directions and a second rotation state with the same rotation direction. The ends of the two clamping plates and the inner wall of the hook body form a clamping space. The clamping space is used for the engagement and disengagement of the wire in the first rotation state of the clamping plates, and the clamping space is used to hold and limit the wire in the second rotation state of the clamping plates. This invention, by setting up a clamping plate and a clamping space, allows for easy engagement or disengagement with the wire in the first rotating state of the clamping plate. In the second rotating state of the clamping plate, it can move with the wire and limit the wire on both sides, keeping the wire within the clamping space and preventing the clamping gap from widening. This effectively prevents the grounding clamp from detaching from the wire. However, the connection point of the grounding wire is still located at the top, which cannot prevent accidental contact caused by the wire connection end breaking and falling off. Therefore, it is necessary to design a power grounding clamp that is highly practical and prevents accidental contact due to wire breakage. Summary of the Invention

[0004] The purpose of this invention is to provide a power grounding clamp to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a power grounding clamp, comprising a bottom terminal, a fixing ring fixedly connected to the top surface of the bottom terminal, a pressing plate provided on the side of the fixing ring, two toothed handles rotatably connected to the front side of the bottom terminal, a partition plate fixedly connected to the ground of the bottom terminal, vertical toothed plates slidably connected to both sides of the partition plate, a wire extrusion hole plate provided on the rear side of the vertical toothed plate, a wire contact piece provided on the rear side of the wire extrusion hole plate, a wire insertion groove provided on the front side of the bottom terminal, a bottom gripping rod fixedly connected to the top of the fixing ring, an arc-shaped slot provided on the side of the vertical toothed plate, and the top front end of the wire extrusion hole plate... The wire extrusion plate is fixedly connected to the bottom surface of the connector end through the inner side of the arc-shaped slot. The connector contacts are symmetrically distributed about the transverse centerline and fixedly connected to the bottom of the connector. The vertical tooth plate is engaged with the toothed handle. Through the above structure, the toothed handle is first rotated counterclockwise upward. Then, one end of the grounding wire is inserted into the insertion slot on the side of the bottom of the connector. At this time, the toothed handle is pressed down, and the toothed handle contacts the outside of the connecting wire through the outer gear, inserting the wire inward. The wire end passes through the arc-shaped slot on the side of the vertical tooth plate. At the same time, the toothed handle deflects, causing the vertical tooth plate to move upward and contact the wire extrusion plate, thereby squeezing and fixing the connector end. At the same time, the wire end is inserted into the connector contact piece for contact and fixing.

[0006] According to the above technical solution, a wire-fixing device is provided above the fixing ring. The wire-fixing device includes a push rod, a push spring is provided on the outer side of the push rod, and a locking groove plate is fixedly connected to the rear end of the push rod. A locking post is provided on the inner side of the locking groove plate, and a compression spring is provided on the outer side of the locking post. A telescopic rod is fixedly connected to the top surface of the locking post. An inner cavity is provided between the telescopic rod and the inner cavity cylinder. A thin flexible tube is fixedly connected to the top end of the inner cavity cylinder, and the end of the thin flexible tube is fixed... A piston cylinder is connected, and an air chamber is provided inside the piston cylinder. A piston block is slidably connected to the inner side of the air chamber. A connecting block slide shaft is fixedly connected to the center of the piston block. A hook rod is fixedly connected to the end of the connecting block slide shaft. A telescopic rod is fixedly connected to the inner cavity cylinder. A bottom grip rod is slidably connected between the telescopic rod and the inner cavity cylinder. A circular hole is opened on the inner side of the telescopic rod, and a locking bead is provided in the circular hole. A ball spring is fixedly connected to the rear side of the locking bead. A retaining ring is slidably connected to a push rod. One end of the push spring... The spring is fixedly connected to the locking slot plate, and the other end of the push spring is fixedly connected to the inner wall of the fixing rod ring. The push rod is fixedly connected to the extrusion plate. The thin hose is interconnected with the air chamber and the inner cavity. The hook rod has an overall arc shape. Through the above structure, when the extrusion plate is pushed, the extrusion plate pushes the push rod to pull the push spring. The push rod moves and simultaneously drives the locking slot plate to move, causing one side of the locking slot plate to move away from the side of the locking column rod, thereby disengaging the locking slot plate and releasing the elastic potential energy of the compressed spring under pressure. Release, which causes the telescopic rod connected above the locking post to pop up. Use your hand to pull the telescopic rod until the ball spring pushes the locking ball out and engages with the end of the bottom grip rod. During this process, as the telescopic rod moves upward, it also moves the inner cavity cylinder fixed on the outside. This gradually increases the space between the inner cavity cylinder and the telescopic rod, allowing air to be drawn from the thin hose connected to the inner cavity cylinder. This allows the air in the air chamber to be drawn through the thin hose, thereby using the reduced air pressure to drive the piston block to move and pull the connecting block slide shaft and hook rod to move.

[0007] According to the above technical solution, the side of the wire fixing device is provided with an auxiliary rod device, the auxiliary rod device includes a rotating handle groove shaft, the surface of the bottom grip rod is provided with a storage side groove, the side of the storage side groove is provided with a sliding long groove, the inner side of the sliding long groove is slidably connected to a rotating rod, the side of the rotating rod is provided with a grip plate, the side of the rotating handle groove shaft is provided with an arc-shaped groove, and the arc-shaped groove fits with the side of the compression spring. The rotating rod is hinged to the middle position of the grip plate, the grip plate is fixedly connected to the rotating handle groove shaft, and the side of the grip plate is provided with a rotating rod groove. Through the above structure, when the compression spring moves upward and pops out, it drives the rotating handle groove shaft on the side to rotate, thereby causing the grip plate connected to the rotating handle groove shaft to disengage from the outer sleeve inner cavity, causing the grip plate to flip, and then causing the rotating rod hinged to the side of the grip plate to slide from the side of the sliding long groove, and making the end of the rotating rod parallel to the grip plate, so as to facilitate the grip of the part.

[0008] According to the above technical solution, a connecting outer rod is fixedly connected to the top of the telescopic rod, and a balancing device is provided at the top of the connecting outer rod. The balancing device includes a pull rod, an outer sleeve rod is fixedly connected to the top surface of the pull rod, an inner retracting rod is slidably connected to the inner side of the outer sleeve rod, a pressing rod block is fixedly connected to the top of the inner retracting rod, and wire clamping ends are connected to the front and rear sides of the pressing rod block. A wire clamping base is hinged to the outer side of the wire clamping end, a pressing spring is provided on the outer side of the top of the inner retracting rod, the wire clamping base is fixedly connected to the bottom clamp, and the top of the pressing spring is fixed to the pressing rod block. The connection includes a groove on the top end of the clamping end, which is slidably connected to the pressing rod block. Through the above structure, by pulling down the pull rod, the pull rod pulls the outer rod, and through the inner retracting rod extending inside the outer rod, it pulls the pressing rod block downward to compress the pressing spring. When the pressing rod block is pressed down, the clamping ends on both sides are simultaneously pressed down and deflected. After the clamping end with the hook rod hooks the conductive wire, the pull rod is released, allowing the clamping end to close with the bottom clamp. At the same time, the insulated clamping end on the other side clamps the remaining wire, thereby making the overall center of gravity vertically downward. The insulation structure at one symmetrical end is used to fix the other wire.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention, by setting up a partition plate, a vertical toothed plate, a wire extrusion hole plate, a wiring contact piece, and a wire insertion groove, allows the wiring head to be connected to the bottom and quickly fixed by a snap-fit ​​connection. While facilitating use, it prevents the wiring from being excessively squeezed and broken, thus protecting the wiring and preventing the high-voltage current from falling and contacting the human body.

[0010] 2. This invention, by setting up a locking post, a compression spring, a locking groove plate, a push rod, a push spring, a locking bead, a ball spring, an inner cavity, and a thin hose, allows the rod body structure to be retracted for easy storage. At the same time, the locking structure is used to open and slide, causing the inner cavity of the sliding structure to expand. During the expansion, the upper end clamping piston contracts, and the piston contraction is used to position the rope, preventing it from coming loose when securing it and providing a fastening effect.

[0011] 3. The present invention, by setting a rotating handle groove shaft, a storage side groove, a sliding long groove, a rotating rod, a grip plate, and a rotating rod groove, the structure drives the grip plate to automatically deflect and pop out.

The terminal 1 is fixedly connected, and the vertical toothed plate 10 is engaged with the toothed handle 3. Through the above structure, the toothed handle 3 is first rotated counterclockwise upward. Then, one end of the grounding wire is inserted into the insertion groove 13 on the side of the bottom end 1 of the terminal. At this time, the toothed handle 3 is pressed down, and the toothed handle 3 contacts the outside of the connecting wire through the outer gear, inserting the wire inward and passing the wire end through the arc-shaped groove on the side of the vertical toothed plate 10. At the same time, the toothed handle 3 deflects, causing the vertical toothed plate 10 to move upward and contact the wire extrusion plate 11, thereby squeezing and fixing the terminal. At the same time, the wire end is inserted into the terminal contact piece 12 for contact and fixing, connecting the terminal to the bottom, and quickly fixing it through the snap-fit ​​connection. While facilitating use, it prevents the terminal from being excessively squeezed and broken, thus preventing the terminal from breaking off and falling off, and protects the terminal. It also prevents the high voltage current in the broken wire from falling and contacting the human body.

[0016] A wire-fixing device 5 is provided above the fixing ring 2. The wire-fixing device 5 includes a push rod 54. A push spring 55 is provided on the outer side of the push rod 54. A locking slot plate 53 is fixedly connected to the rear end of the push rod 54. A locking pin 51 is provided on the inner side of the locking slot plate 53. A compression spring 52 is provided on the outer side of the locking pin 51. A telescopic rod 14 is fixedly connected to the top surface of the locking pin 51. An inner cavity 58 is provided between the telescopic rod 14 and the inner cavity 6. A thin hose 59 is fixedly connected to the top end of the inner cavity 6. A piston cylinder 610 is fixedly connected to the end of the thin hose 59. An air chamber 611 is provided inside the piston cylinder 610. A piston block 612 is slidably connected to the inner side of the air chamber 611. A connecting block is fixedly connected to the axis of the piston block 612. A sliding shaft 613 is connected to a hook rod 614 at its end. A telescopic rod 14 is fixedly connected to the inner cavity 6. A bottom grip rod 15 is slidably connected between the telescopic rod 14 and the inner cavity 6. A circular hole is provided on the inner side of the telescopic rod 14, and a locking bead 56 is provided in the hole. A ball spring 57 is fixedly connected to the rear side of the locking bead 56. A fixed rod ring 2 is slidably connected to a push rod 54. One end of a push spring 55 is fixedly connected to a locking groove plate 53, and the other end of the push spring 55 is fixedly connected to the inner wall of the fixed rod ring 2. The push rod 54 is fixedly connected to a compression plate 4. A thin hose 59 is connected to the air chamber 611 and the inner cavity 58. The hook rod 614 is arc-shaped. A cylindrical terminal on the inner side of the fixed rod ring 2 is used to guide the wire. The wire passes through the hole in the top of the inner cavity 6 and connects to the clamping end 87. Through this structure, when the extrusion plate 4 is pushed, it pushes the push rod 54, which in turn pulls the push spring 55. The push rod 54 moves, simultaneously moving the locking slot plate 53, causing one side of the locking slot plate 53 to move away from the side of the locking post 51. This disengages the locking slot plate 53 and releases the elastic potential energy of the compressed spring 52, causing the telescopic rod 14 connected above the locking post 51 to pop upwards. With manual assistance, the telescopic rod 14 is pulled until the ball spring 57 pushes the locking bead 56 out and engages with the end of the bottom grip rod 15. During this process, the telescopic rod 14 moves upwards, simultaneously moving the outer fixed inner cavity 6, thus allowing the inner cavity 6 and the telescopic rod 15 to engage. The space between the retracting rods 14 gradually increases, allowing air to be drawn from the thin flexible tube 59 connected to the inner cavity cylinder 6. This causes the air in the air chamber 611 to be drawn through the thin flexible tube 59, thereby reducing the air pressure and moving the piston block 612, which in turn pulls the connecting block sliding shaft 613 and the hook rod 614. This retracts the rod structure for easy storage. At the same time, the locking structure springs open the sliding mechanism, causing the inner cavity of the sliding structure to expand. During the expansion, the upper clamp piston contracts, using the piston contraction to position the rope, preventing it from coming loose when securing the line and providing a fastening effect. The retracting of the rod structure makes it easy to store. At the same time, the locking structure springs open the sliding mechanism, causing the inner cavity of the sliding structure to expand. During the expansion, the upper clamp piston contracts, using the piston contraction to position the rope and prevent it from coming loose when securing the line.

[0017] An auxiliary rod device 510 is provided on the side of the wire fixing device 5. The auxiliary rod device 510 includes a rotating handle groove shaft 511. A storage side groove 512 is formed on the surface of the bottom grip rod 15. A sliding elongated groove 513 is formed on the side of the storage side groove 512. A rotating rod 514 is slidably connected to the inner side of the sliding elongated groove 513. A grip plate 515 is provided on the side of the rotating rod 514. An arc-shaped groove is formed on the side of the rotating handle groove shaft 511, and the arc-shaped groove fits with the side of the compression spring 52. The rotating rod 514 is hinged to the middle position of the grip plate 515. The grip plate 515 is fixedly connected to the rotating handle groove shaft 511. A groove is formed on the side of the grip plate 515. Through the above structure, the compression spring 52, during its upward movement and ejection, drives the rotating handle groove shaft 511 on the side to rotate, thereby causing the grip plate 515 connected to the rotating handle groove shaft 511 to disengage from the outer sleeve inner cavity 6, allowing the grip plate 515 to flip. This causes the rotating rod 514, which is hinged to the side of the grip plate 515, to slide from the side of the sliding long groove 513, and the end of the rotating rod 514 to be parallel to the grip plate 515, making it easier to hold the part. Through the above structure, the grip plate 515 is automatically deflected and ejected. The grip plate 515 can be used to hold the part, which can increase the stability of lifting the rod body upward, reduce the top sway amplitude, and improve stability.

[0018] The top of the telescopic rod 14 is fixedly connected to a connecting outer rod 7. A balancing device 8 is installed at the top of the connecting outer rod 7. The balancing device 8 includes a pull rod 81. An outer rod 82 is fixedly connected to the top surface of the pull rod 81. An inner retracting rod 83 is slidably connected to the inner side of the outer rod 82. A pressing rod block 84 is fixedly connected to the top of the inner retracting rod 83. A wire clamping end 87 is connected to the front and rear sides of the pressing rod block 84. A wire clamp base 85 is hinged to the outer side of the wire clamping end 87. A pressing spring 88 is installed on the outer side of the top of the inner retracting rod 83. The wire clamp base 85 is fixedly connected to the bottom clamp 86. The top of the pressing spring 88 is fixedly connected to the pressing rod block 84. A groove is formed on the side of the top end of the wire clamping end 87, and the groove is connected to the pressing spring. The rod block 84 is slidably connected. Through the above structure, by pulling down the pull rod 81, the pull rod 81 pulls the outer rod 82, and through the inner retracting rod 83 extending inside the outer rod 82, it pulls the pressure rod block 84 downward to compress the pressure spring 88. When the pressure rod block 84 is pressed down, the clamping ends 87 on both sides are pressed down and deflected. After the clamping end 87 on the side with the hook rod 614 hooks the conductive wire, the pull rod 81 is released, and the clamping end 87 closes with the bottom clamp 86. At the same time, the insulated clamping end 87 on the other side clamps the remaining wire, so that the overall center of gravity is vertically downward. The insulation structure at one symmetrical end fixes the other wire, thereby keeping the whole body balanced and preventing the overall wind force from affecting the swing and causing the fixed wire to fall off.

[0019] Working principle: First, rotate the toothed handle 3 counterclockwise upwards. Then, insert one end of the grounding wire into the insertion slot 13 on the side of the bottom end 1 of the connector. At this time, press down the toothed handle 3. The toothed handle 3 contacts the outside of the connecting wire through the outer gear and inserts the wire inwards. The wire end passes through the arc-shaped slot on the side of the vertical tooth plate 10. At the same time, the toothed handle 3 deflects, causing the vertical tooth plate 10 to move upwards and contact the wire extrusion plate 11, thereby squeezing and fixing the connector end. At the same time, the wire end is inserted into the connector contact piece 12 for contact and fixing. The connector end is connected to the bottom and quickly fixed by snap-fit ​​connection. While facilitating use, it prevents the connector from being broken due to excessive squeezing, thus preventing the connector from breaking off and falling off. It plays a protective role for the connector and prevents the high voltage current in the broken wire from falling and contacting the human body. When the extrusion plate 4 is pushed, it pushes the push rod 54, which in turn pulls the push spring 55 to stretch. The movement of the push rod 54 simultaneously moves the locking slot plate 53, causing one side of the locking slot plate 53 to move away from the side of the locking post 51. This disengages the locking slot plate 53 and releases the elastic potential energy of the compressed spring 52, causing the telescopic rod 14 connected above the locking post 51 to pop upwards. With manual assistance, the telescopic rod 14 is pulled until the ball spring 57 pushes the locking ball 56 out and engages with the end of the bottom grip rod 15. During this process, the telescopic rod 14 moves upwards... While moving, the outer fixed inner cylinder 6 moves together, which gradually increases the space between the inner cylinder 6 and the telescopic rod 14, allowing air to be drawn from the thin hose 59 connected to the inner cylinder 6. This allows the air in the air chamber 611 to be drawn through the thin hose 59, thereby using the reduced air pressure to drive the piston block 612 to move and pull the connecting block sliding shaft 613 and the hook rod 614 to move, thus retracting the rod body structure for easy storage. At the same time, the locking structure is used to spring open the sliding, causing the inner cavity of the sliding structure to expand. When expanding, the upper end clamp piston contracts, and the piston contraction is used to position the rope. During the upward ejection process, the compression spring 52 drives the rotating handle groove shaft 511 on the side to rotate, thereby causing the grip plate 515 connected to the rotating handle groove shaft 511 to disengage from the outer sleeve inner cavity cylinder 6, causing the grip plate 515 to flip, and then causing the rotating rod 514 hinged to the side of the grip plate 515 to slide from the side of the sliding long groove 513, and making the end of the rotating rod 514 parallel to the grip plate 515 to facilitate the grip of the part. Through the above structure, the grip plate 515 is automatically deflected and ejected. Pulling down the lever 81 causes the outer rod 82 to be pulled, and the inner retracting rod 83 extending inside the outer rod 82 pulls the pressure block 84 downward to compress the pressure spring 88. When the pressure block 84 is pressed down, the clamping ends 87 on both sides are pressed down and deflected. After the clamping end 87 on the side with the hook rod 614 hooks the conductive wire, the lever 81 is released, and the clamping end 87 closes with the bottom clamp 86.
