The end of each spring 85 is fixedly connected with a slider 83. The slider 83 is slidably connected inside the sliding groove 84 and is fixedly connected with the lock block 87.

[0026] By connecting the box body 1 and the box cover 2 through the safety lock 8, the anti-theft performance of the optical cable splicing box is improved, the circuit of the cable 5 inside the box body 1 is prevented from being stolen by outsiders, the phenomenon of the network being stolen inside the cable box is prevented, and the use safety of the network is improved.

[0027] Referring to Figures 1 to 5, in order to prevent the plug 15 of the cable 5 from being pulled out of the box body 1 when the box cover 2 is not opened, a plurality of interfaces 18 are vertically provided on both the upper and lower sides of the optical cable element 13. Each interface 18 is plugged with a plug 15, and each end of each plug 15 is connected to a cable 5. A plurality of second card slots 12 adapted to the plugs 15 are opened on the outer side of the rectangular frame 11. Each second card slot 12 is provided with a plug 15. Each plug 15 is horizontally provided with a blind hole 16 on the outside, and each blind hole 16 is plugged with a positioning block 19.

The diameter of the second arc surface 17 is greater than the diameter of the cable 5, and the diameter of the second arc surface 17 is smaller than the size of the cross section of the plug 15.

[0028] By limiting the plug 15 and the optical cable element 13 through the blind hole 16 and the positioning slot, and at the same time opening the first card slot 9 on the box body 1 and arranging the card block 10 fixed to the box cover 2 in the first card slot 9, it is avoided that the plug 15 is pulled out of the box body 1 under the action of external force when the box cover 2 is not opened, and at the same time it is also avoided that the poaching personnel insert the external connecting cable 5 into the box body 1.

[0029] Refer to Figure 1 , in order to facilitate the installation of the box body 1 on a flat surface and an arc-shaped wall, two mounting plates 4 that are vertically mirror-symmetrical up and down are fixedly connected to the rear side of the box body 1. A plurality of countersunk holes 3 that are equidistantly distributed are horizontally penetrated through the front side of each mounting plate 4. The rear sides of the two mounting plates 4 are vertically provided with a first arc surface 6.

And setting the box body 1 and the box cover 2 as metal materials improves the anti-destruction performance of the box body 1 and improves the overall strength of the box body 1. Heat dissipation holes 7 are provided on both sides of the box body 1 to dissipate the heat generated when the optical cable element 13 in the box body 1 is running.

[0031] Working principle: When in use, when it is necessary to separate the lid 2 from the box body 1, first insert two keys into the two lock cores 82 on the outer side of the lid 2 at the same time, and then rotate the two lock cores 82 at the same time. The key on the left rotates clockwise, and the lock core 82 on the right rotates counterclockwise. The lock core 82 drives the gear 88 to rotate. The gear 88 drives the lock block 87 to move through the toothed plate meshing with it, so that the lock block 87 moves from the lock hole 14 in the box body 1 to the receiving groove 86 in the lid 2. At the same time, the spring 85 is compressed. Then, the lid 2 is directly pulled outwards. When the lid 2 is separated from the box body 1, the clamping block 10 is driven to disengage from the first card slot 9, and at the same time, the positioning block 19 disengages from the blind hole 16 on the plug 15. Then, after the plug 15 is pulled out vertically and taken out towards the front side of the box body 1, the cable 5 is disengaged from the first card slot 9, thereby completing the disassembly of the cable 5 in the box body 1, and further improving the anti-theft performance of the cable 5 in the box body 1.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention.
