DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Refer to the instruction manual Figure 1-5 , a cable live detection tool, such as Figure 1 As shown, it includes a mobile support mechanism 1, and a tensioning mechanism 2 and a detection mechanism 3 are fixedly installed on the top of the mobile support mechanism 1;

[0024] Reference Figure 2-4As shown, the tensioning mechanism 2 includes at least two tripods 21, and a first supporting rod 22 and a second supporting rod 23 are fixedly installed on one side of the two tripods 21. A guide groove 24 is provided on one side of the two tripods 21 in a through-shape, and a limiting slider 25 is slidably installed in the inner cavity of the guide groove 24. A third supporting rod 26 is fixedly installed at one end of the limiting slider 25, and a power component for driving it to move is fixedly connected to the end of the limiting slider 25 away from the third supporting rod 26. In actual use, when the height of the third supporting rod 26 is changed by starting the power component, the tension of the cables sequentially wound around the outer walls of the first supporting rod 22, the third supporting rod 26 and the second supporting rod 23 can be adjusted, so that the cable of the to-be-detected section remains in a straight state, so that in subsequent detection and use, the outer wall of the cable of the to-be-detected section is evenly stressed, thereby improving the accuracy of the detection.

[0025] Further, refer to Figure 3 As shown, the power assembly includes a threaded screw 27 rotatably mounted on the tripod 21 on a side away from the first holding rod 22. The threaded screw 27 and the guide groove 24 are arranged in parallel with each other. The outer wall of the threaded screw 27 is threadedly connected with an internal threaded sleeve 28. The internal threaded sleeve 28 and the limit slider 25 are fixedly connected. The purpose of this arrangement is that by rotating the threaded screw 27, the internal threaded sleeve 28 moves on the outer wall of the threaded screw 27, and at the same time, the limit slider 25 can be synchronously driven to slide in the inner cavity of the guide groove 24, thereby adjusting the horizontal height of the third holding rod 26. Therefore, it can be flexibly adjusted according to the different tension levels of the cable, so that the cable to be tested is always kept in a straight state for testing.

[0026] Among them, reference Figure 4 As shown, the first supporting rod 22 and the second supporting rod 23 are arranged on the same horizontal line, and the first supporting rod 22, the second supporting rod 23 and the third supporting rod 26 are arranged in parallel with each other, and the third supporting rod 26 is always arranged on the top of the first supporting rod 22 and the second supporting rod 23. The purpose of such arrangement is that when the tightness of the cable to be detected is poor, the cable to be detected can be passed through the bottom of the second supporting rod 23 and around the top of the third supporting rod 26 in sequence, and then passed out from the bottom of the first supporting rod 22. Then, by adjusting the height of the third supporting rod 26, when limiting the position of the cable to be detected, it can be adjusted according to the tightness of the cable to be detected, so that the cable to be detected can always remain in a straight state during the detection process, so as to improve the stability and accuracy of subsequent detection;

[0027] Further, refer to Figure 2As shown, the mobile support mechanism 1 includes a balance frame 101 fixedly mounted on the bottom of two tripods 21, and a plurality of movable wheels 102 are fixedly mounted on the bottom of the balance frame 101, and the two tripods 21 are symmetrically arranged about the vertical center line of the balance frame 101. The purpose of such arrangement is to make the overall structure of the device compact. When used for detection, the cable of the to-be-detected section can be tightened and adjusted by adjusting the height of the third supporting rod 26. It is very convenient to carry and more convenient for practical use.

[0028] As a further extension of this scheme, refer to Figure 2 and Figure 5 As shown, the detection mechanism 3 includes a support frame 31 fixedly mounted at the vertical center line position of the balance frame 101, and a first limiting sleeve 32 is fixedly mounted on one side of the support frame 31, and a second limiting sleeve 33 is rotatably mounted inside the first limiting sleeve 32, and the outer wall of the first limiting sleeve 32 is provided with a first through slot 34, and the outer wall of the second limiting sleeve 33 is provided with a second through slot 35, and the first through slot 34 and the second through slot 35 are connected to each other under normal conditions. The purpose of such a setting is to enable the tensioning mechanism 2 to allow the cable to be tested to move into the inner cavity of the first limiting sleeve 32 and the second limiting sleeve 33 through the connected first through slot 34 and second through slot 35 before tightening and adjusting the cable to be tested, and then rotate the second limiting sleeve 33 to make the second through slot 35 move away from the first through slot 34, so that the cable to be tested can be trapped in the inner cavity of the first limiting sleeve 32 and the second limiting sleeve 33;

[0029] At the same time, two first elastic pressure plates 36 set in an inclined state are fixedly installed on the inner wall of the first limiting sleeve 32, and two second elastic pressure plates 37 set in an inclined state are fixedly installed on the inner wall of the second limiting sleeve 33. The inner walls of the two first elastic pressure plates 36 and the second elastic pressure plates 37 are fixedly installed with charged detection probes 38. Under normal circumstances, the second elastic pressure plates 37 and the first elastic pressure plates 36 are kept on the same horizontal line. After the cable to be detected is circled inside the first limiting sleeve 32 and the second limiting sleeve 33, the position of the second elastic pressure plate 37 can be rotated and adjusted so that the two first elastic pressure plates 36 and the second elastic pressure plates 37 are respectively on the center lines of two different directions of the first limiting sleeve 32, so that multiple charged detection probes 38 are evenly limited on the outer wall of the cable to be detected. When the device is activated, the contact between the multiple live detection probes 38 and the outer wall of the cable remains stable, thereby improving the overall detection stability and accuracy. Among them, a positioning rod 39 is fixedly installed on the outer wall of the second limit sleeve 33, and a positioning sleeve 310 is fixedly installed on the top of the support frame 31. The positioning rod 39 is engaged in the inner cavity of the positioning sleeve 310, and the positioning rod 39 and the positioning sleeve 310 are arranged in a mutually magnetic state. The purpose of this arrangement is that when the second limit sleeve 33 is rotated and the second elastic pressure plate 37 is moved to the horizontal center line position of the first limit sleeve 32, the positioning rod 39 can be engaged in the inner cavity of the positioning sleeve 310, and the position of the second limit sleeve 33 is limited and fixed, so that the live detection probes 38 set on the first elastic pressure plate 36 and the second elastic pressure plate 37 can remain stable when moving.
