A guide shaft is fixedly connected in the middle of each of the three sets of clearance grooves. T-shaped sliders are slidably connected to each of the three sets of T-shaped slides. The right end of the internal thread sleeve abuts against the left end of each of the three sets of T-shaped sliders. A transmission rod is rotatably connected to the inner side of each of the three sets of T-shaped sliders. A guide groove is provided on each of the three sets of transmission rods to match the guide shaft. The transmission rod is movably fitted onto the guide shaft through the cooperation of the guide groove, and the transmission rod passes through the clearance groove. An arc-shaped clamp is rotatably connected to the end of each of the three sets of transmission rods away from the T-shaped slider. The three sets of arc-shaped clamps are equidistantly arranged in a ring inside the support sleeve.

[0008] Preferably, the inner side of the T-shaped slider and the outer side of the arc-shaped clamping plate are provided with connecting grooves that cooperate with the transmission rod.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] Example

[0023] Please see Figures 1-7This utility model discloses a power conductor clamping device, comprising a bracket 1 and a support sleeve 6. Four sets of countersunk holes 2 are symmetrically formed through the front end of the inner side of the bracket 1. A set of right support plates 3 and left support plates 4 are symmetrically fixedly connected to the front end and bottom end of the inner side of the bracket 1. A limiting platform 7 is integrally fixedly connected to the left end of the support sleeve 6. The support sleeve 6 is fixedly connected to two sets of right support plates 3, and the limiting platform 7 is fixedly connected to two sets of left support plates 4. External threads 8 are provided on the outer wall of the support sleeve 6 starting from the left end. An internally threaded sleeve 9 is screwed onto the support sleeve 6 through the mating of the external threads 8. A handle 19 is fixedly connected to the outer wall of the threaded sleeve 9. Three sets of T-shaped grooves 10 are equidistantly arranged in a ring on the outer wall of the support sleeve 6. The right end of the external thread 8 extends to the middle of the T-shaped groove 10. Each of the three sets of T-shaped grooves 10 has a relief groove 11 at its bottom, and the relief groove 11 communicates with the inner wall of the support sleeve 6. A guide shaft 12 is fixedly connected to the middle of each of the three sets of relief grooves 11. A T-shaped slider 13 is slidably connected to each of the three sets of T-shaped grooves 10. The right end of the internal threaded sleeve 9 abuts against the left end of each of the three sets of T-shaped sliders 13. A transmission rod 14 is rotatably connected to the inner side of each of the three sets of T-shaped sliders 13. Each of the three sets of transmission rods 14 has a guide groove 15 that matches the guide shaft 12. The transmission rods 14 are movably mounted on the guide shaft 12 through the guide grooves 15, and the transmission rods 14 pass through the clearance grooves 11. The ends of the three sets of transmission rods 14 away from the T-shaped slider 13 are rotatably connected to arc-shaped clamping plates 16. The three sets of arc-shaped clamping plates 16 are equidistantly arranged in a ring inside the support sleeve 6. In use, the bracket 1 can be fixed in the appropriate position with bolts through the countersunk holes 2. When clamping the power wire, the power wire is passed through the space between the three sets of arc-shaped clamping plates 16 and through the support sleeve 6. By rotating the internal threaded sleeve 9 counterclockwise using the throttle 19, the internal threaded sleeve 9 moves to the right, thereby pushing the three sets of T-shaped sliders 13 to slide to the right along the T-shaped groove 10. When the T-shaped sliders 13 slide to the right, with the cooperation of the guide shaft 12 and the guide groove 15, the T-shaped sliders 13 push the arc-shaped clamping plates 16 inward through the transmission rod 14, thereby clamping and fixing the power wire through the three sets of arc-shaped clamping plates 16. This improves the clamping effect on the power wire, prevents the power wire from coming off during the clamping process, and improves practicality.

[0024] The inner side of the T-shaped slider 13 and the outer side of the arc-shaped clamping plate 16 are both provided with connecting grooves 17 that cooperate with the transmission rod 14. The two ends of the transmission rod 14 are rotatably connected to the inner side of the T-shaped slider 13 and the outer side of the arc-shaped clamping plate 16 respectively through the cooperation with the connecting grooves 17, and the width of the transmission rod 14 is the same as that of the clearance groove 11. By setting the connecting groove 17 to cooperate with the transmission rod 14 and setting the width of the clearance groove 11 and the transmission rod 14 to be the same, axial wobbling can be avoided when the transmission rod 14 rotates, thereby improving the smoothness of the transmission of the transmission rod 14.

[0025] The limiting platform 7 is screwed with a tightening bolt 20 on its edge, and the tightening bolt 20 is tightened at the left edge of the internal threaded sleeve 9. By setting the tightening bolt 20, after the power wire is clamped by the arc-shaped clamping plate 16, the tightening bolt 20 is tightened to press the tightening bolt 20 onto the internal threaded sleeve 9, thereby preventing the internal threaded sleeve 9 from rotating on its own, and ensuring that the clamping of the power wire by the arc-shaped clamping plate 16 will not loosen.

[0026] Anti-slip pads 18 are fixedly connected to the inner walls of the three sets of arc-shaped clamps 16; by setting anti-slip pads 18, the arc-shaped clamps 16 can clamp the power wires more tightly and reliably.

[0027] The rear end of the bracket 1 is fixedly connected to a fastening pad 21; by setting the fastening pad 21, the bracket 1 can be installed more tightly and securely during installation.

[0028] This utility model discloses a power wire clamping device. In operation, a suitable hexagonal socket head cap screw is used to fix the bracket 1 in a proper position. When clamping the power wire, the power wire passes through the three sets of arc-shaped clamping plates 16 and the support sleeve 6. Initially, the handle 19 faces inward towards the bracket 1. By rotating the handle 19 counterclockwise, the internal threaded sleeve 9 moves to the right, thereby pushing the three sets of T-shaped sliders 13 to slide to the right along the T-shaped groove 10. The T-shaped sliders 13 slide to the right... At this time, with the cooperation of the guide shaft 12 and the guide groove 15, the T-shaped slider 13 pushes the arc-shaped clamp 16 to move inward through the transmission rod 14, and then the power wire is clamped and fixed by the three sets of arc-shaped clamps 16. At this time, the throttle 19 faces the outside of the bracket 1. After the arc-shaped clamp 16 clamps the power wire, the tightening bolt 20 is tightened so that the tightening bolt 20 presses against the internal thread sleeve 9, thereby preventing the internal thread sleeve 9 from rotating on its own, so as to ensure that the clamping of the power wire by the arc-shaped clamp 16 will not loosen.

[0029] The present invention relates to a power conductor clamping device, the installation method, connection method or setting method of which are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
