Description

Technical Field

[0001] The utility model belongs to the technical field of grounding wire clamps, and in particular relates to a grounding wire clamp which is easy to assemble and disassemble. Background Art

[0002] The grounding wire clamp is one of the common grounding components, which is mainly used for grounding cables. The grounding wire is an important tool to ensure the safety of operators and electrical equipment when voltage unexpectedly appears on the power-off equipment.

[0003] The Chinese patent application number CN202321294135.4 discloses a grounding wire clamp, including: a body, the body defines a chamber and has a first side portion, the first side portion includes a narrow hole and a first hole, the narrow hole and the first hole are both connected to the chamber, and the first side portion also includes a plurality of blind holes arranged around the first hole; a screw rod, the screw rod is rotatably supported in the chamber; a first clamping jaw, the first clamping jaw is connected to the first side portion; a second clamping jaw, the second clamping jaw arranged opposite to the first clamping jaw includes a protrusion protruding toward the chamber through the narrow hole, the protrusion is sleeved on the screw rod and is threadedly connected to the screw rod; a positioning knob, the positioning knob includes a knob body, a connecting rod and a latch connected to the knob body, the knob body is provided with a through hole, the connecting rod passes through the first hole and is connected to the screw rod through a transmission member, and the positioning latch can pass through the through hole and be accommodated in one of the plurality of blind holes. The grounding wire clamp disclosed in the present invention can effectively prevent loosening after clamping the power-off equipment. However, when the above device is actually used, the movement of the lower clamping jaw is controlled by rotating the knob body. On the one hand, the knob body is elastically fitted with a pin, and the pin needs to be pulled all the time when the knob body is rotated, which is inconvenient to use. On the other hand, the method of rotating the knob body to drive the screw to adjust the lower clamping jaw is slow, which is not convenient for quick disassembly and assembly of the grounding wire clamp.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0026] See also Figure 1-4 As shown, in this embodiment, a grounding clamp that is easy to disassemble and assemble is provided, including a rod body 1, a lower clamping jaw 2 is installed on one side of the rod body 1, an upper clamping jaw 3 is slidably matched on one side of the rod body 1, and the lower clamping jaw 2 and the upper clamping jaw 3 are elastically matched;

[0027] A moving seat 4 is installed on one side of the upper clamping jaw 3, and the moving seat 4 is slidably fitted in the rod body 1. A slider 5 is slidably fitted on one side of the moving seat 4, and a limiting rod 6 is elastically fitted in the slider 5. A limiting groove 7 that cooperates with the limiting rod 6 is opened on one side of the inner wall of the moving seat 4. A fixed cylinder 8 is installed at the bottom of the moving seat 4, and a rotating rod 9 is rotatably fitted in the rod body 1. A fixed rod 10 that cooperates with the fixed cylinder 8 is installed at one end of the rotating rod 9.

[0028] The application of one aspect of this embodiment is as follows: when in use, the staff takes the rod body 1 to drive the lower clamping jaw 2 and the upper clamping jaw 3, so that the cable to be grounded is located between the lower clamping jaw 2 and the upper clamping jaw 3, and then pulls the rod body 1 to move downward. At this time, the cable presses against the upper clamping jaw 3 and moves slightly upward. The movement of the upper clamping jaw 3 drives the movable seat 4 and the limit rod 6 to move. The limit rod 6 moves out of the limit of the limit groove 7, and then the lower clamping jaw 2 and the upper clamping jaw 3 clamp the cable through elastic force. Then the staff rotates the rotating rod 9, and the rotating rod 9 rotates to drive the fixing rod 10 to fix the fixing cylinder 8. The fixing cylinder 8 fixes the movable seat 4 and the upper clamping jaw 3, and then the lower clamping jaw 2 and the upper clamping jaw 3 can be connected to the ground wire to complete the grounding of the equipment.

[0029] By means of the limit rod 6, the limit rod 6 and the limit groove 7 can limit the upper clamping jaw 3. When clamping the line, the upper clamping jaw 3 is pulled to make the limit rod 6 disengage from the limit groove 7, so that the lower clamping jaw 2 and the upper clamping jaw 3 can clamp the cable, which is convenient for the staff to use. By means of the rotating rod 9, after the lower clamping jaw 2 and the upper clamping jaw 3 clamp the cable, the rotating rod 9 can be rotated to drive the fixing rod 10 to fix the fixing cylinder 8, so that the fixing cylinder 8 can fix the movable seat 4 and the upper clamping jaw 3, so that the clamping of the lower clamping jaw 2 and the upper clamping jaw 3 to the cable is more stable, and the operation is simple and convenient.

[0030] like Figure 4 As shown, the limiting groove 7 of this embodiment includes a first groove 701 and a second groove 702 opened on one side of the inner wall of the rod body 1, the second groove 702 is hook-shaped, the depth of the second groove 702 is greater than the first groove 701, the first groove 701 is connected to the second groove 702, and one end of the second groove 702 is provided with an oblique groove 703 connected to the first groove 701, and the limiting rod 6 slides with the first groove 701, the second groove 702 and the oblique groove 703 respectively. Through the set second groove 702, when the limiting rod 6 is located at the top of the second groove 702, the limiting rod 6 is limited by the second groove 702. After pulling the upper clamp 3, the limiting rod 6 moves away from the hook of the second groove 702, and the limiting rod 6 slides along the second groove 702 and the inclined groove 703 into the first groove 701. At this time, the lower clamp 2 and the upper clamp 3 can be closed by elastic force to clamp the cable. Pulling the upper clamp 3 again can make the upper clamp 3 drive the limiting rod 6 along the first groove 701 into the second groove 702, so that the limiting rod 6 is limited by the second groove 702. At this time, the lower clamp 2 and the upper clamp 3 are open, which is convenient for the cable to enter between the lower clamp 2 and the upper clamp 3.

[0031] like Figure 2-3As shown, one end of the rotating rod 9 of this embodiment is slidably matched with the fixed cylinder 8, and the other end of the rotating rod 9 that passes through the bottom of the rod body 1 is equipped with a rotating wheel 13, a sliding groove 11 is provided on one side of the fixed cylinder 8, and a plurality of fixed grooves 12 that are connected to the sliding groove 11 are provided on one side of the fixed cylinder 8, and the fixed rod 10 is slidably matched in the sliding groove 11, and the fixed rod 10 is matched with the fixed groove 12. By setting the sliding groove 11, when the upper clamping jaw 3 drives the moving seat 4 and the fixed cylinder 8 to move, the fixed rod 10 slides in the sliding groove 11, and the rotating rod 9 is rotated to drive the fixed rod 10 to rotate into the fixed groove 12, so as to fix the fixed cylinder 8.

[0032] like Figure 3-4 As shown, the lower clamping jaw 2 and the upper clamping jaw 3 of this embodiment are provided with arc grooves 14 on opposite sides, and a protective pad 15 is installed in the arc groove 14. Through the arc groove 14, when the lower clamping jaw 2 and the upper clamping jaw 3 are closed to clamp the cable, the limit position is located between the two arc grooves 14, so that the protective pad 15 protects the cable.

[0033] like Figure 2-4 As shown, the lower clamping jaw 2 and the upper clamping jaw 3 of this embodiment are provided with a plurality of grooves 16 on opposite sides, and a spring 17 is installed between two opposite grooves 16. Through the provided grooves 16, when the lower clamping jaw 2 and the upper clamping jaw 3 are closed, the spring 17 can be received in the two grooves 16, so that the lower clamping jaw 2 and the upper clamping jaw 3 can be closed to the maximum extent.

[0034] like Figure 3-4 As shown, one side of the lower clamping jaw 2 and the upper clamping jaw 3 of this embodiment is equipped with a terminal 18, and the terminal 18 is used to connect the ground wire.
