Description
Technical field
The utility model relates to a kind of strengthening core, in particular to a kind of nonmetallic strengthening core of resistance to compression bend-resistance.
Background technique
Optical fiber is widely applied as quick and stable signal vehicle in communication field.Since optical fiber is fragile, tension
Stretching property and bend-resistance are all very poor, need that strengthening core is added in optical cable in actual use to promote optical cable to protect optical fiber
Stretch-resistance and bend-resistance.Most of existing strengthening core is solid cylinder structure, and good branch can be played to optical cable
Support effect, but crushing resistance and bend-resistance are insufficient.
Utility model content
The technical issues of the utility model solves is to provide a kind of nonmetallic strengthening core of resistance to compression bend-resistance, has very strong anti-
Pressure property and bend-resistance.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of nonmetallic reinforcement of resistance to compression bend-resistance
Core, including protective layer and intensive aspect；The intensive aspect is internally provided with deformation chamber；The reinforcement external surface is provided with bending resistance
Slot.When the strengthening core is under pressure, internal distortions chamber can play buffer function, enhance the resistance to compression of strengthening core by deformation
Property；When reinforcing chip bending, the resistance to curved groove with slight deformation, can alleviate the stretching of strengthening core two sides and the degree that is squeezed, and play
Enhance the effect of strengthening core bend-resistance.
Further, the intensive aspect is a kind of reeded cylindrical structure in surface.Intensive aspect is by binder and adds
Strong fiber composition；Reinforcing fibre is wrapped in interior and is solidified into cylindrical structure by the binder.
Further, the protective layer is evenly coated at reinforcement external surface.The protective layer is coated on outside intensive aspect
Surface avoids intensive aspect directly and optical fiber contact, prevents intensive aspect because friction generates powder.
Further, there are two the resistance to curved grooves, central symmetry of two resistance to curved grooves with respect to intensive aspect.Two resistance to curved grooves
The extruding force that curved interior is formed by material aggregation can be alleviated when strengthening core bending, promote the bend-resistance of strengthening core
Property.
Further, the deformation chamber is parallelogram sturcutre.Deformation occurs when the deformation chamber is under pressure, pressure
Power restores original shape after cancelling, and plays the role of buffering decompression by deformation, promotes the crushing resistance of strengthening core.
Detailed description of the invention
Fig. 1 is strengthening core cross-sectional structure schematic diagram.
In the figure, it is marked as protective layer 100, intensive aspect 200, resistance to curved groove 220, deformation chamber 300.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of nonmetallic strengthening core of resistance to compression bend-resistance, including protective layer 100 and intensive aspect 200；It is described to add
Strong body 200 is internally provided with deformation chamber 300；200 outer surface of intensive aspect is provided with resistance to curved groove 220.The strengthening core by
When pressure, internal distortions chamber 300 can play buffer function, enhance the crushing resistance of strengthening core by deformation；When reinforcing chip bending,
The resistance to curved groove 220 with slight deformation, can alleviate the stretching of strengthening core two sides and the degree that is squeezed, to promote strengthening core folding
Curved property.
On the basis of the above, as shown in Figure 1, the intensive aspect 200 is a kind of reeded cylindrical structure in surface.Bonding
More reinforcing fibres are wrapped in interior and curing molding by agent；Epoxy resin can be selected in curing agent, have chemical property it is stable and at
The high feature of toughness after type is common adhesives in industry；Glass fibre material can be selected in reinforcing fibre or aramid fiber is fine
Tie up material；Glass fibre material quality is crisp, and crushing resistance is weaker；Aramid fiber material is light-weight, intensity is high, toughness is strong, compares glass
Fiber is more resistant to corrosion.This example selects epoxy resin as binder, and aramid fiber improves strengthening core as reinforcing fibre
Toughness and tensile strength.
On the basis of the above, as shown in Figure 1, the protective layer 100 is evenly coated at 200 outer surface of intensive aspect.Protective layer
100 can directly contact optical fiber to avoid intensive aspect 200, prevent intensive aspect 200 because of friction and generate powder.The protective layer
100 optional polyethylene (PE) or polypropylene (PP) material, this example are selected polyethylene material as protective layer, are had wear-resisting
Corrosion resistant advantage.
On the basis of the above, as shown in Figure 1, there are two the resistance to curved grooves 220, two opposite intensive aspects 200 of resistance to curved groove 220
Central symmetry.Two resistance to curved grooves 200 can alleviate curved interior because of material by slight deformation when strengthening core is bent
The extruding force of material aggregation and formation, promotes the bend-resistance of strengthening core.
On the basis of the above, as shown in Figure 1, the deformation chamber 300 is parallelogram sturcutre.Intensive aspect 200 is pressed
When power, deformation chamber 300 can play the role of buffering decompression by way of deformation, to improve the crushing resistance of strengthening core.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects
Step is described in detail, it should be understood that being not limited to this foregoing is merely specific embodiment of the utility model
Utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all wrap
Containing being within the protection scope of the utility model.
