DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail with reference to the embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] According to Figure 1 、 2, as shown in Figures 3 and 4, this embodiment provides a mine cable protection clip, which includes a fixed plate 1, a movable plate 2 and a clamping cylinder 3, and is characterized in that: a movable plate 2 is provided on one side of the fixed plate 1, and a plurality of clamping cylinders 3 are fixedly connected to one side of the movable plate 2. A clamping mechanism for fixing the cable is provided inside the clamping cylinder 3. First, the fixed plate 1 is fixed on the wall of the mine tunnel, then the movable plate 2 is fixed on one side of the fixed plate 1, and then the cable is restricted on the clamping cylinder 3 through the clamping mechanism, which is used to fix the clamping cylinder 3 on the wall of the mine tunnel and separate multiple cables from each other to avoid safety accidents caused by entanglement with each other.

[0020] The clamping mechanism includes a left clamping block 4, a right clamping block 5, a circular hole 6, a threaded rod 7 and a gland 8. A left clamping block 4 is fixedly connected to one end of the clamping cylinder 3, and a right clamping block 5 is provided at one end of the left clamping block 4. Circular holes 6 are provided inside one end of the clamping cylinder 3, the left clamping block 4 and the right clamping block 5. A threaded rod 7 is threadedly connected to the end of the clamping cylinder 3 far away from the movable plate 2, and a gland 8 is rotatably connected to one end of the threaded rod 7.

[0021] A spring 9 is provided between the right clamping block 5 and the gland 8. The diameter of the spring 9 is smaller than the diameters of the gland 8 and the right clamping block 5. The outer walls of the left clamping block 4 and the right clamping block 5 are in fit connection with the inner wall of the clamping cylinder 3.

[0022] Insert one end of the cable into the inside of the circular hole 6 and penetrate it. The cable squeezes the spring 9 through the right clamping block 5 to a compressed state, and then the elastic force generated by the spring 9 drives the right clamping block 5 to reset to pre-clamp the cable. Then turn the threaded rod 7 to drive the gland 8 to move towards the right clamping block 5, and the gland 8 squeezes the spring 9 to the limit state to top the right clamping block 5 and the left clamping block 4 tightly, so that the cable is completely limited inside the clamping cylinder 3. When it is necessary to release the limited state, turn the threaded rod 7 in the reverse direction to drive the gland 8 away from the right clamping block 5.

[0023] Tightening bolts 11 are symmetrically inserted at the top and bottom of the fixed plate 1. One end of the tightening bolt 11 is threadedly connected with a nut. A tensioning mechanism is provided on the tightening bolt 11. The tensioning mechanism includes a clamping cylinder 10 and an inserting rod 12. One end of the tightening bolt 11 is fixedly connected with a clamping cylinder 10. A conical groove is provided inside the clamping cylinder 10. An inserting rod 12 is inserted into the tightening bolt 11. When the fixed plate 1 is fixed, drill a hole in the wall of the mine tunnel in advance, fit the fixed plate 1 on the tunnel wall, and the mounting holes on the fixed plate 1 are parallel to the positions of the drilled holes. Then insert the inserting rod 12 into the tightening bolt 11. After the inserting rod 12 contacts the conical groove, it squeezes the clamping cylinder 10 to move outwards to tension the outer wall of the clamping cylinder 10 and the inner wall of the drilled hole. Then turn the nut at one end of the tightening bolt 11 to move towards the fixed plate 1, and use the nut to clamp the fixed plate 1 tightly, so that the fixed plate 1 is completely fixed on the wall of the mine tunnel.

[0024] One end of the fastening bolt 11 is fixedly connected with a clamping block 13. An L-shaped bracket is arranged on one side of the clamping block 13. A connecting mechanism is arranged between the movable plate 2 and the L-shaped bracket. The connecting mechanism includes a limiting block 14 and a connecting bolt 15. The upper and lower ends of the back side of the movable plate 2 are welded with the limiting block 14. One end of the limiting block 14 is clamped and connected with one side of the L-shaped bracket, and the limiting block 14 and the L-shaped bracket are detachably connected through the connecting bolt 15. Along the inner wall of the L-shaped bracket, one end of the limiting block 14 is clamped into its inner side. At this time, the movable plate 2 is located on one side of the fixed plate 1. The connecting bolt 15 is screwed into the inside of the limiting block 14 and the clamping block 13 to fix the clamping block 13 and the limiting block 14 together, that is, to fix the movable plate 2 on one side of the fixed plate 1, so as to drive the movable plate 2 of the clamping cylinder 3 to be fixed on the wall of the mine tunnel.

[0025] For this mine cable protection clip, one end of the cable is inserted into the inside of the round hole 6 and penetrates out. The cable squeezes the spring 9 through the right clamping block 5 to be in a compressed state. Then the elastic force generated by the spring 9 drives the right clamping block 5 to reset to pre-clamp the cable. Then the threaded rod 7 is rotated to drive the pressing cover 8 to move towards the direction of the right clamping block 5. The pressing cover 8 squeezes the spring 9 to the limit state to tightly press the right clamping block 5 and the left clamping block 4, so that the cable is completely limited inside the clamping cylinder 3.
