[0027] The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different parts. The words "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of including other elements. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] like Figures 1 to 9 As shown, the distribution network fault location device, such as Figures 1 to 9 As shown, it includes an upper shell 1 and a lower shell 2, one side of the upper shell 1 and the lower shell 2 are hinged, and the other side of the upper shell 1 and the lower shell 2 are connected by a detachable connecting mechanism 5. Semicircular wire grooves 3 are opened at both ends of the upper shell 1 and the lower shell 2, and the wire grooves of the upper shell 1 and the lower shell 2 are spliced ​​into a circular hole. The ends of the upper shell 1 and the lower shell 2 are evenly provided with adjustable clamping mechanisms 4 around the circular hole; the adjustable clamping mechanism 4 has a support plate 41 fixedly set at the end of the upper shell 1 or the lower shell 2, and an adjusting bolt 42 is vertically threadedly connected to the support plate 41. A support cylinder 44 perpendicular to the axial direction of the wire groove 3 is rotatably provided on the end of the adjusting bolt 42 close to the wire groove 3; in this embodiment, the detachable connecting mechanism 5 is opened, and the The wire grooves 3 of the upper shell 1 and the lower shell 2 correspond to the cables and are mounted on the outside of the cables. The upper shell 1 and the lower shell 2 are then merged together and connected and fixed through a detachable connecting mechanism 5. The adjustable clamping mechanism 4 is adjusted to make it abut against the outside of the cable to achieve the installation of the distribution network fault locating device, which is not easy to loosen and cause cable wear. The adjustable clamping mechanism 4 can be adjusted according to different cable outer diameters to meet the fixed installation requirements of cables with different outer diameters, with a wide range of applications and reduced costs. By rotating the adjusting bolt 42, the threaded structure between the adjusting bolt 42 and the support plate 41 cooperates, driving the adjusting bolt 42 to move relative to the support plate 41, thereby driving the support cylinder 44 to move, thereby achieving clamping and fixing of cables with different outer diameters.

[0029] In some embodiments, swivels 45 are mounted on the outer sides of both ends of the support tube 44. The outer sides of the swivels 45 have anti-slip strips 46 in a circular array as an integral structure. The anti-slip strips 46 can increase the friction between the swivels 45 and the cable, making it less likely for sliding friction to occur between the swivels 45 and the cable. The swivels 45 and the cable have rolling friction, thereby reducing the wear on the cable. Specifically, the swivels 45 are rotatably connected to the support tube 44 via bearings.

[0030] In some embodiments, two guide rods 43 parallel to the adjusting bolts 42 are fixedly provided on the support tube 44, and the guide rods 43 are slidably connected to the support plate 41. The support tube 44 is slidably connected to the support plate 41 through the guide rods 43, so that the support tube 44 will not rotate relative to the support plate 41, thereby improving the stability of the movement of the support tube 44.

[0031] In some embodiments, Figure 5 , 8As shown in Figure 9, an upper strip 11 is fixedly provided on one side of the upper shell 1 close to the detachable connecting mechanism 5, a lower strip 21 is fixedly provided on one side of the lower shell 2 close to the detachable connecting mechanism 5, an insert block is fixedly provided on one side of the upper strip 11 close to the lower strip 21, a socket 22 matching the insert block 12 is provided on the lower strip 21, a socket 121 is provided inside the plug block 12, and plug rods 55 matching the socket 121 are slidably provided inside the lower strip 21 on both sides of the socket 22; the upper shell 1 and the lower shell 2 are closed, the upper slat 11 is in contact with the lower slat 21, the plug block 12 is inserted into the inside of the socket 22, the plug rod 55 is moved, and the plug rod 5 is inserted into the inside of the hole 121, so that the plug block and the socket 22 can be locked, that is, the fixed connection between the upper shell 1 and the lower shell 2 is achieved; when it is necessary to open the upper shell 1 and the lower shell 2, the plug rod 55 is moved and the plug rod 55 is pulled out from the inside of the hole 121, so that the plug block and the socket 22 can be released, and the upper shell 1 and the lower shell 2 can be removed and opened.

[0032] In some embodiments, a slideway 211 is provided inside the lower slat 21, and a slider 56 matching the slideway 211 is fixedly provided on the outer side of the insertion rod 55.

A slide groove 52 matching the pull rod 51 is provided on the lower slat 21, and the pull rod 51 can move inside the slide groove 52 to insert the insertion rod 55 into the interior of the socket 121, or pull it out from the interior of the socket 121, thereby realizing the locking or release between the plug block 12 and the socket 22.

[0033] In some embodiments, a spring 57 is provided between the end of the slide 211 facing away from the socket 121 and the slider 56. The spring 57 applies elastic force to the slider 56 so that the slider 56 is located at one end inside the slide 211, so that the insertion rod 55 can remain inserted into the socket 121.

[0034] In some embodiments, Figure 2 and 5 As shown, a locking mechanism 6 is provided on the pull rod 51, and the locking mechanism 6 is used to lock or release the pull rod 51 and the lower slat 21.

After the detachable connecting mechanism 5 locks the upper shell 1 and the lower shell 2, the hand nut 61 is tightened to make the hand nut 61 press against the outer side of the lower slat 21, thereby locking the pull rod 51 and the lower slat 21, so as to prevent the pull rod 51 from moving during use and causing the insertion rod 55 to fall out of the inside of the hole 121, thereby accidentally opening the upper shell 1 and the lower shell 2.

[0036] In some embodiments, Figure 5 and 6 As shown, a locking groove 54 is provided on the outer side of one end of the slide groove 52 close to the plug block 12, and a clamping platform 62 matching the locking groove 54 is fixedly provided on one side of the hand nut 61.

[0037] In some embodiments, a baffle 53 is fixedly provided on the outer side of the pull rod 51 . The baffle 53 and the pull rod 51 are an integral structure. The pull rod 51 limits the hand nut 61 to prevent the hand nut 61 from detaching from the pull rod 51 .
