Abstract
The utility model discloses a kind of bend-resistant electric cable protection tube; comprise at least two-layer pipe box; from the inside to the outside; the hardness of each pipe box progressively reduces; innermost layer pipe box has ring-cutting form or the spiral helicine endless groove of continuous print along its length; the outer surface of innermost layer pipe box is provided with the groove distributed along its length, is provided with the elastic reactance bracing wire of motion by above-mentioned indentation limitations in above-mentioned groove, outermost layer pipe box adopts resin material to make.Bend-resistant electric cable protection tube disclosed in the utility model, can prevent cable from producing overbending.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of bend-resistant electric cable protection tube.
Background technology
Along with the quick raising of human being's production power, cable is widely used in electric power, field of communication transmission.Exterior cable by wrapping up with protective sleeve, thus prevents heart yearn to be in loose condition (of surface).Because heart yearn flexibility is higher, be easy to bending, and the bending side pressure produced may cause transmission performance to worsen, and therefore needs to prevent overbending, meanwhile, due to the needs installed, requirement can bend in the reasonable scope again.In prior art, the concaveconvex structure that the periphery being typically employed in protective sleeve arranges ring cutting obtains the effect preventing overbending, but said structure easily produces distortion and lost efficacy after alternating bending, needs to improve.
Utility model content
In order to solve the technical problem existed in background technology, the utility model proposes a kind of bend-resistant electric cable protection tube, can prevent cable from producing overbending.
A kind of bend-resistant electric cable protection tube that the utility model proposes; comprise at least two-layer pipe box; from the inside to the outside; the hardness of each pipe box progressively reduces; innermost layer pipe box has ring-cutting form or the spiral helicine endless groove of continuous print along its length; the outer surface of innermost layer pipe box is provided with the groove distributed along its length, is provided with the elastic reactance bracing wire of motion by above-mentioned indentation limitations in above-mentioned groove, outermost layer pipe box adopts resin material to make.
Preferably, sleeve pipe quantity is two-layer.
Preferably, endless groove extends to innermost layer clear internal diameter face, and endless groove seamed edge adjacent one another are contacts with each other.
In the utility model; by arranging endless groove on innermost layer pipe box; less simultaneously by the hardness Design of the larger and outer pipe box of the hardness Design of innermost layer pipe box; when cable be subject to larger bending time; endless groove is conflicted mutually near side, innermost layer clear internal diameter face; cable can be prevented to be excessively bent, and outer pipe box can form protection to the heart yearn of cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bend-resistant electric cable protection tube that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of bend-resistant electric cable protection tube that the utility model proposes.
The utility model proposes a kind of bend-resistant electric cable protection tube; comprise two-layer pipe box; the hardness of internal layer pipe box 2 is greater than the hardness of outer pipe box 1; internal layer pipe box 2 has ring-cutting form or the spiral helicine endless groove of continuous print along its length 3; the outer surface of internal layer pipe box 2 is provided with the groove 4 distributed along its length; be provided with the elastic reactance bracing wire 5 that motion limits by above-mentioned groove 4 in above-mentioned groove 4, outer pipe box 1 adopts resin material to make.
By arranging endless groove 3 on innermost layer pipe box 2; less simultaneously by the hardness Design of the larger and outer pipe box 1 of the hardness Design of innermost layer pipe box 2; when cable be subject to larger bending time; endless groove 3 is conflicted mutually near innermost layer pipe box 2 aperture surface side; cable can be prevented to be excessively bent, and outer pipe box 1 can form protection to the heart yearn of cable.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
