Description
Technical field
The utility model belongs to cable protection technical field.
Background technology
Optical fiber, abbreviation optical fiber is a kind of up to the total reflection principle biography for causing light in fiber made of glass or plastics
Defeated light conduction instrument.Optical cable is that a number of optical fiber forms the cable heart according to certain way, is surrounded by sheath, some also claddings outside
Outer jacket, to realize a kind of communication line of optical signal transmission.
With the development of power communication, the laying of optical cable spreads all over the world.Optical cable has the laying such as aerial, direct-burried, pipeline, bottom
Mode.Aerial optical cable is that frame hangs over the optical cable used on electric pole.This system of laying can utilize original aerial line pole line,
Save construction cost, shorten the construction period.Aerial optical cable is hung on electric pole, it is desirable to adapts to various natural environments.Aerial optical
Cable is easily threatened by natural calamities such as typhoon, ice slush, floods, also easily by external force influenceed and mechanical strength itself weaken etc. shadow
Ring, therefore the failure of aerial optical cable is multiple.
In order to protect optical cable, prior art is directly socketed in outside optical cable using protection pipe more, but these protection pipes are equal
It is hard long tube, once circuit breaks down, then needing optical cable being completely withdrawn from outside outlet pipe to be repaired.Meanwhile rain
During snowy day gas, sleet is easily deposited in outside pipe, for a long time meeting corrosion protection pipe, reduces the service life of protection pipe.
Utility model content
The utility model is to solve existing optical cable protective tube inconvenient maintenance, and easily accumulation sleet service life is short
Problem, now provide a kind of optical cable protective tube.
A kind of optical cable protective tube, including pipe clamp 1 and body 2,
Pipe clamp 1 is rubber tri-prismoid, and the bottom surface of the tri-prismoid is isosceles triangle, square where isosceles triangle base
Shape plane is axially provided with the bar-shaped trough 1-2 of both ends open along pipe clamp 1, and bar-shaped trough 1-2 cross section is T-shaped,
Body 2 is rubber body, and the cross section of body 2 is isosceles trapezoid, and the upper bottom surface of body 2 is provided with strip bulge 2-1,
Strip bulge 2-1 cross section is T-shaped, and the top half of body 2 is together with strip bulge 2-1 along its longitudinal axis to splitting in left and right
Symmetrical two parts,
Strip bulge 2-1 can be embedded in bar-shaped trough 1-2, and the two can be fitted close,
The base length of isosceles triangle is more than the upper bottom length of isosceles trapezoid,
The length of pipe clamp 1 is less than the length of body 2.
Preferably, two neighboring pipe clamp 1 is coordinated by grafting and is attached.
Preferably, the bottom of body 2, which is hung, connects multiple masses.
A kind of optical cable protective tube described in the utility model, pipe clamp 1 are rubber tri-prismoid, its drift angle all the time upward, when
When running into sleety weather, sleet can slide from inclined-plane, prevent from, in protection pipe surface sediment, reducing rate of corrosion.The utility model profit
Body is clamped with multiple pipe clamps, when a certain section of circuit breaks down, certain section can be carried out to dismounting maintenance, reduce workload.
A kind of optical cable protective tube described in the utility model is applied to lightguide cable link protection field.

Embodiment
Embodiment one：Present embodiment, a kind of light described in present embodiment are illustrated referring to figs. 1 to Fig. 4
Cable protection pipe, including pipe clamp 1 and body 2,
Pipe clamp 1 is rubber tri-prismoid, and the bottom surface of the tri-prismoid is isosceles triangle, square where isosceles triangle base
Shape plane is axially provided with the bar-shaped trough 1-2 of both ends open along pipe clamp 1, and bar-shaped trough 1-2 cross section is T-shaped,
Body 2 is rubber body, and the cross section of body 2 is isosceles trapezoid, and the upper bottom surface of body 2 is provided with strip bulge 2-1,
Strip bulge 2-1 cross section is T-shaped, and the top half of body 2 is together with strip bulge 2-1 along its longitudinal axis to splitting in left and right
Symmetrical two parts,
Strip bulge 2-1 can be embedded in bar-shaped trough 1-2, and the two can be fitted close,
The base length of isosceles triangle is more than the upper bottom length of isosceles trapezoid,
The length of pipe clamp 1 is less than the length of body 2.
In present embodiment, bar-shaped trough 1-2 is set in the length direction along tri-prismoid bottom center position along pipe clamp 1,
And it is the groove of both ends open.Strip bulge 2-1 bottom midline positions along in isosceles trapezoid are set.The top half of body 2 cut open to
At holes for optical cables 3 so that left-right parts you can separate and expose holes for optical cables 3, additionally it is possible to fit together so that holes for optical cables 3
Cross section is merged into complete circle.
Present embodiment is in practical application, the top half of body 2 is divided right and left, it would be desirable to which the optical cable of protection is placed
In holes for optical cables 3, then by the fitting close to each other of left and right two parts so that strip bulge 2-1 is merged, then by bar shaped
Groove 1-2 one end is inserted from strip bulge 2-1 one end so that strip bulge 2-1 is embedded in bar-shaped trough 1-2, reaches utilization
The purpose that pipe clamp 1 clamps body 2.Meanwhile pipe clamp 1 is shorter than body 2, body 2 is clamped using multiple pipe clamps 1, and multiple pipes
Press from both sides 1 end to end, when needing repairing certain part, directly disassemble the pipe clamp 1 of part to be repaired, it becomes possible to tieed up
Repair, avoid the trouble for completely taking out cable.
Pipe clamp 1 and body 2 assembling finish when so that the tip of pipe clamp 1 upward, when running into sleety weather, sleet dust edge
Hypotenuse slides, it is not easy to accumulates, reduces the rate of corrosion of body.And the base of isosceles triangle protrudes from the upper of isosceles trapezoid
Bottom both sides, prevent sleet from penetrating between pipe clamp 1 and body 2 in the gap joined, and plus T-slot and raised and cooperation side
Formula, can also avoid the infiltration of sleet, further reach the purpose of protection.Meanwhile present embodiment uses the pipe of quality of rubber materials
Body and pipe clamp, pliability is strong, and when running into strong wind weather or extraneous strength, body is not easily broken, and extends service life.
Embodiment two：Present embodiment is that a kind of optical cable protective tube described in embodiment one is made into one
Step illustrates, in present embodiment, two neighboring pipe clamp 1 is coordinated by grafting to be attached.
The structure of present embodiment is in practical application, one end of a pipe clamp 1 is covered by the other end of its adjacent pipe clamp 1
Lid, even if there is liquid to penetrate into the gap of the two handing-over, it will not also penetrate into immediately on optical cable, serve the effect of isolation.
Embodiment three：Present embodiment is that a kind of optical cable protective tube described in embodiment one or two is made
Further illustrate, in present embodiment, the bottom of body 2, which is hung, connects multiple masses.
In present embodiment, the bottom of body 2, which is hung, connects multiple masses, plays a part of the pendant that hangs down so that the drift angle of pipe clamp 1 begins
On all morning, prevent optical cable protective tube from being inverted in strong wind weather, ensure that the effect of pipe clamp 1 blocks sleet.
