wherein: 1. optical cable, 2, nylon corrugated pipe, 3, metal collar, 4, fixing hole, 5, fixing sheet, 6, positioning ring, 7, positioning mechanism, 71, connecting ring, 72, connecting chain, 73 and hook.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The corner protection device for laying optical cables, as shown in fig. 1, includes an optical cable 1, a nylon corrugated tube 2, a metal collar 3, a fixing hole 4, a fixing sheet 5, a positioning ring 6, a positioning mechanism 7, a connecting ring 71, a connecting chain 72, and a hook 73.
The nylon corrugated pipe 2 is sleeved at the corner of the optical cable 1, so that the optical cable 1 can be well protected from being damaged in the bending and transportation processes. The upper and lower parts of nylon corrugated pipe 2 are all sleeved with metal clamping rings 3, and metal clamping rings 3 are annular and used for limiting nylon corrugated pipe 2. The metal collar 3 comprises two parts with the same structure, and the two parts are fixedly connected together through the fixing holes 4, the fixing rod, the metal collar 3 and the positioning mechanism 7.
The fixed stationary blade 5 that is the rectangle that is provided with on 3 lateral walls of metal rand, stationary blade 5 sets up along 3 lateral wall length direction of metal rand, and has seted up on the stationary blade 5 and be circular shape fixed orifices 4. Set the dead lever in the fixed orifices 4, the dead lever is L type, vertical setting in fixed orifices 4 for bury underground, increase the stability of integrated device.
The metal retainer ring 3 is fixedly provided with a circular positioning ring 6 on the side wall of the same radial tangent plane as the fixing sheet 5, and the positioning ring 6 is hinged with a positioning mechanism 7 for positioning the two metal retainer rings 3.
The positioning mechanism 7 comprises a connecting ring 71, a connecting chain 72 and a hook 73, wherein the connecting ring 71 is buckled on the positioning ring 6. The connecting ring 71 is fixedly connected with a connecting chain 72, the connecting chain 72 can be bent, and a plurality of small holes are uniformly formed in the connecting chain 72.
