DETAILED DESCRIPTION

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of the application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0022] Reference Figure 1-Figure 3 A protective mechanism for an overhead cable comprises two protective sleeves 1. Two first L-shaped plates 2 are fixed to the top outer wall of the protective sleeve 1 by bolts. A plurality of slide grooves 15 and card slots 16 are provided on one side of the first L-shaped plate 2, and the corresponding slide grooves 15 are communicated with the card slots 16. A connecting rod 14 is slidably connected in the slide groove 15. A supporting plate 8 is fixed to the bottom end of the connecting rod 14 by bolts. Two fixing plates 11 are fixed to the upper surface of the supporting plate 8 by bolts. Two guide rods 12 are inserted into one side of the fixing plate 11. A wedge block 13 is fixed between the two guide rods 12 by bolts. The guide rod 12 can guide the wedge block 13 so that it can move stably. A spring 10 is welded on one side of the wedge block 13 for resetting it, and the spring 10 is spring-loaded to the bottom end of the connecting rod 14. The spring 10 is fixed to the fixing plate 11, and multiple grooves 7 are provided on both sides of the first L-shaped plate 2, and the grooves 7 are plugged into the wedge-shaped blocks 13. The bottom of the support plate 8 is fixed with a fixing ring 5 by bolts. The connecting rod 14 is moved upward, so that the support plate 8 drives the fixing ring 5 to move upward. At the same time, the wedge-shaped block 13 moves upward so that it is squeezed by the bottom of the first L-shaped plate 2, so that the wedge-shaped block 13 moves outward, and the spring 10 contracts until the wedge-shaped block 13 is stuck in the groove 7. At this time, the fixing ring 5 moves upward and is fixed, and then the two protective sleeves 1 are stuck to the outside of the cable from top to bottom, so that the fixing ring 5 of appropriate size clamps the cable, and then the bolts are inserted into the fixing hole 6 to achieve the fixation between the two fixing rings 5. A limiting component is provided on the top of the first L-shaped plate 2.

[0023] In the present invention, it should be noted that the limiting assembly includes a threaded rod 19, which is rotatably connected to one side of the first L-shaped plate 2, and the outer side of the threaded rod 19 is threadedly connected to the second L-shaped plate 3. The threaded rod 19 is rotated to make the second L-shaped plate 3 move along the threaded rod 19. A positioning column 18 is fixed to one side of the first L-shaped plate 2 by bolts, and the positioning column 18 is slidably connected to the second L-shaped plate 3. The positioning column 18 can guide the second L-shaped plate 3 so that it can move stably. One end of the guide rod 12 passes through the fixed plate 11 and is fixed to the baffle 9 by bolts. The baffle 9 can limit the moving distance of the guide rod 12. The top of the connecting rod 14 is fixed with a block 17 by bolts, and the block 17 is slidably connected to the slot 16. The block 17 can limit the height of the connecting rod 14 moving downward. The second L-shaped plate 3 is in contact with the block 17. The second L-shaped plate 3 can limit the position of the block 17, so that the fixing ring 5 can stably clamp the cable. A sealing ring 4 is bonded to one side of the fixing ring 5. The sealing ring 4 makes the connection between adjacent fixing rings 5 ​​tighter. Both sides of the protective sleeve 1 are fixed with fixing holes 6 by bolts.

[0024] Working principle: When it is necessary to install protection for the cable, first determine the appropriate size of the fixing ring 5 according to the size of the cable, rotate the threaded rod 19 to move the second L-shaped plate 3, so that the second L-shaped plate 3 only rests against the block 17 corresponding to the fixing ring 5 that needs to be used, and move the two corresponding upper and lower fixing rings 5 ​​that are smaller than the cable size to an open state, that is, move the connecting rod 14 upward, so that the support plate 8 drives the fixing ring 5 to move upward, and at the same time, the wedge block 13 moves upward so that it is squeezed by the bottom of the first L-shaped plate 2, so that the wedge block 13 moves outward, and the spring 10 contracts until the wedge block 13 is stuck in the groove 7. At this time, the fixing ring 5 moves upward and is fixed, and then the two protective sleeves 1 are stuck up and down to the outside of the cable, so that the fixing ring 5 of the appropriate size clamps the cable, and then the bolt is inserted into the fixing hole 6 to achieve fixation between the two fixing rings 5.

[0025] The present invention has been described through the above-mentioned embodiments. Those skilled in the art will appreciate that the present invention is not limited to the above-mentioned embodiments, and more modifications may be made according to the teachings of the present invention. These modifications are all within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
