SPECIFIC IMPLEMENTATION MANNERS

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0026] As Figures 1 to 5As shown in the figure, an insulating live working wire support includes a fixed cylinder 1, a support plate 2 fixedly connected to the bottom end of the fixed cylinder 1. A support mechanism 31 is arranged inside the fixed cylinder 1, and a clamping and limiting mechanism 32 is arranged on the support mechanism 31. The support mechanism 31 includes a lead screw 311 rotatably connected to the top end of the support plate 2 through a bearing. A handle 312 is fixedly connected to the outer wall of the end of the lead screw 311 away from the bearing. A threaded sleeve 313 is threadedly connected to the outer wall of the lead screw 311. A first hinge seat 314 is fixedly connected to the outer wall of the threaded sleeve 313. A connecting rod 315 is rotatably connected to the first hinge seat 314. The end of the connecting rod 315 away from the first hinge seat 314 is rotatably connected to a second hinge seat 316. A slider 317 is fixedly connected to the outer wall of the second hinge seat 316. A sliding rod 318 is slidably connected to the inner wall of the slider 317. A rotating groove is opened on the outer wall of the top end of the fixed cylinder 1, and a rotating shaft 3111 is rotatably connected to the inner wall of the rotating groove. A support rotating plate 319 is fixedly connected to the outer wall of the rotating shaft 3111. A sliding groove is opened on the inner side outer wall of the support rotating plate 319, and the upper and lower ends of the sliding rod 318 are fixedly connected to the inner wall of the sliding groove. An inclined plate 3110 is fixedly connected to the inner side outer wall of the support rotating plate 319. One end of the outer wall of the first hinge seat 314 is fixedly connected to a pressing plate 3112.

[0027] Furthermore, the number of the support rotating plates 319 is three, and the support rotating plates 319 are evenly and equidistantly distributed on the outer wall of the fixed cylinder 1, so that the three cables can be supported, ensuring that the three cables can be separated from each other to prevent contact during the support process.

[0028] Furthermore, the number of the inclined plates 3110 is two, and the inclined plates 3110 are symmetrically distributed on the inner side outer wall of the support rotating plate 319 in a left-right symmetric structure. An inclined surface is opened on the outer wall of the end of the pressing plate 3112 away from the first hinge seat 314, and the inclined surface is in fit with the outer wall inclined surface of the inclined plate 3110, so as to ensure that the inclined surface of the pressing plate 3112 is in close fit with the inclined surface of the inclined plate 3110, increasing the contact area with the inclined plate 3110 and ensuring the pressing rotation of the support rotating plate 319.

[0029] Even further, the inner wall of the sliding groove opened on the inner side outer wall of the support rotating plate 319 is in fit with the outer wall of the slider 317, so as to ensure the close fit between the slider 317 and the inner wall of the sliding groove, thereby improving the stability of the slider 317 during the movement on the inner wall of the sliding groove.

[0030] The clamping and limiting mechanism 32 includes a connecting plate 321 fixedly connected to one end outer wall of the support rotating plate 319. A clamping ring 322 is fixedly connected to one end outer wall of the connecting plate 321. A groove is opened on the outer wall of the clamping ring 322, a rotating hole is opened on the inner wall of the groove, a torsion spring 323 is fixedly connected to the inner wall of the rotating hole, a rotating rod 324 is fixedly connected to the end of the torsion spring 323 away from the rotating hole, a clamping plate 325 is fixedly connected to the end of the rotating rod 324 away from the torsion spring 323, and a limiting block 326 is fixedly connected to the inner wall of the clamping ring 322.

[0031] Further, the number of snap rings 322 is three, and the snap rings 322 are evenly and equidistantly distributed on the outer wall of one end of the three support rotating plates 319, so that the three cables can be clamped and limited.

[0032] Furthermore, the length of the clamping plate 325 is longer than the distance between the bottom end of the limiting block 326 and the outer wall of the top end of the rotating rod 324, so that the clamping plate 325 can be pressed and blocked by the limiting block 326, and thus a closed limiting effect can be formed between the clamping plate 325 and the snap ring 322.

[0033] The implementation principle of an insulating live working wire support in this embodiment is as follows: First, fix the three cables on the snap rings 322, and then turn the handle 312 to drive the lead screw 311 to rotate. By rotating the lead screw 311, the threaded sleeve 313 can be driven to move upward. By moving the threaded sleeve 313, the first hinge seat 314 and the connecting rod 315 can be driven to move upward, and at the same time, the pressing plate 3112 can also be driven to move upward. By moving the connecting rod 315, the second hinge seat 316 can be driven to move upward. By moving the second hinge seat 316, the slider 317 can be driven to move upward on the outer wall of the sliding rod 318. At this time, during the upward movement of the pressing plate 3112, it will exert a pressing effect on the inclined plate 3110. The inclined plate 3110 subjected to the pressing will drive the support rotating plate 319 to rotate outward through the rotation of the rotating shaft 3111. At the same time, phase rotation can be generated through the first hinge seat 314 and the second hinge seat 316. As the three support rotating plates 319 rotate outward, the three fixed cables can be driven to move away from each other, and at the same time, the three cables can be supported and fixed to prevent the three cables from coming into contact and causing danger. This facilitates the staff to support and fix the cables and facilitates the work operation.

[0034] When fixing the cable, first dial the clamping plate 325 into the inside of the snap ring 322. At this time, the clamping plate 325 will drive the rotating rod 324 to rotate. By rotating the rotating rod 324, the torsion spring 323 can be driven to rotate. At this time, the clamping plate 325 will rotate to the inside of the snap ring 322, so that the closure of the snap ring 322 can be opened. Then, the cable can be placed on the upper half inside the snap ring 322. After placing it, release the clamping plate 325. The torsion spring 323 rebounds to drive the clamping plate 325 to reset and then move to the limiting block 326. Blocked by the limiting block 326, the snap ring 322 is closed again, and thus the clamping and limiting effect on the cable can be completed.
