Compared with the prior art, the utility model provides an optical cable fixing device possesses following beneficial effect:

this optical cable fixing device passes circular through-hole by keeping away from the wire pole side with the optical cable taut to the wire pole direction, and at this moment, outside-in's power makes the movable block of both sides about to both sides withdrawal, and the movable block can not hinder the passing through of optical cable, makes the optical cable pass circular through-hole smoothly. After the optical cable is tensioned, when the weight of the optical cable gives a force in the direction far away from the telegraph pole, the movable blocks on the upper side and the lower side clamp the optical cable under the action of the spring, and particularly when the surfaces of the movable blocks are uneven, the force for clamping the optical cable is increased. From this, the installer only need with the optical cable through the through-hole taut can, need not to rotate the screw rod again under taut state. The steel ball is arranged to clamp the optical cable, the extrusion force of the optical cable can be buffered, the damage to the surface of the optical cable caused by overlarge force is prevented, and the purpose of protecting the optical cable is achieved. The utility model discloses reduced the number of times that the optical cable was fixed to the manual rotatory screw rod of installer, reduced the installation difficulty for the installation rate is fixed effectual.

In the figure: 1 telegraph pole, 2 fixed frames, 3 fixed frames, 4 fixed rods, 5 threaded sleeves, 6 fixed blocks, 7 circular through holes, 8 movable grooves, 9 movable blocks, 10 springs, 11 blocks and 12 openings.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment of the optical cable fixing device comprises a telegraph pole 1, wherein a fixing frame 2 is arranged at the top of the telegraph pole 1, a fixing frame 3 is fixedly connected to one end of the fixing frame 2, a fixing rod 4 is fixedly connected to the inside of the fixing frame 3, and a threaded sleeve 5 is connected to the top of the fixing rod 4 in a threaded manner. The one end fixedly connected with fixed block 6 of fixed frame 3 is kept away from to mount 2, the circular through-hole 7 that supplies the optical cable to pass through is seted up at the middle part of fixed block 6, and the diameter of circular through-hole 7 is unanimous with the optical cable size, and movable groove 8 has respectively been seted up to circular through-hole 7 top and below, be equipped with the opening between movable groove 8 and the circular through-hole 7, it is provided with movable block 9 to be close to circular through-hole 7 position in movable groove 8, set up the opening that is less than the movable block diameter between movable groove 8 and the circular through-hole 7, movable block 9 is connected in spring 10 one end, and the spring 10 other end is fixed in on sprue 11, sprue 11. The cross section of the movable block 9 is circular.
