Abstract
The utility model provides a kind of cable middle connector, including inner support tube and the elastic rubber set that is coated on outside inner support tube, and there is gradually narrowed taper portion, the middle part inner surface of the taper portion to be fixed with annular fill-in pad at the both ends of the elastic rubber set.The utility model is simple in structure, gradually narrowed two-end structure cooperation middle part is used in utility model middle connector can fill-in pad of the deformation for gap between fill pipe outer surface and elastic rubber set, it can be better achieved to more intermediate cables simultaneously and sealing, make up deficiency of the existing middle connector only for single pipeline fixing seal.
Description
Technical field
The utility model is related to a kind of cable middle connectors.
Background technology
Existing cable middle connector generally deals with the exterior protection at single pipe joint, in some certain pipelines
May also include more branch line connecting portions, the jointing of the single tubulose connecting pipeline adjacent when coating more pipelines
And to be the cyclic annular matching part to the inner surface and more pipelines that will appear jointing have gap with jointing, from
And leakproofness is insufficient.
Invention content
The utility model improves the above problem, i.e., the technical problems to be solved in the utility model is existing electricity
Cable middle connector and defective tightness in more pipeline engagement process.
The specific embodiment of the utility model is：A kind of cable middle connector, including inner support tube and be coated on
The both ends of elastic rubber set outside inner support tube, the elastic rubber set have gradually narrowed taper portion, the taper portion
Middle part inner surface be fixed with annular fill-in pad.
Further, the taper portion outboard end has elastic bulge loop.
Further, the outer surface of the taper portion is arranged at intervals with salient point, and adhesive tape is wound on the outside of taper portion.
Further, the taper portion inner surface is located between annular fill-in pad and elastic bulge loop with section in T-shaped
Annular groove.
Compared with prior art, the utility model has the advantages that：It is adopted in the utility model middle connector
With gradually narrowed two-end structure cooperation middle part can deformation for gap between fill pipe outer surface and elastic rubber set
Fill-in pad can have the sealing effect for greatly improving more pipelines while cladding, avoid being influenced by external environment.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model taper portion structural schematic diagram.
Specific implementation mode
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~2, a kind of cable middle connector, including inner support tube 10 and be coated on outside inner support tube
Elastic rubber set 20, inner support tube 10 is to be inserted in the plastic pipe sleeve of pipeline in elastic rubber set for convenience at initial stage, is used
When can will realize that elastic rubber set is contracted to the outer surface of pipeline after its direct pull.
In the present embodiment, the both ends of elastic rubber set there is gradually narrowed taper portion 120, the taper portion
120 middle part inner surface is fixed with annular fill-in pad 110, and 110 material of the annular fill-in pad is the higher sponge of density, in this way
When elastic rubber set is shunk according to line size, it is close to play reinforcing to be wrapped in the outside of pipeline for its sponge meeting synchronous
The effect of envelope, on the other hand, the taper portion outboard end have an elastic bulge loop 40, elastic bulge loop play the role of reinforcing rib from
And leakproofness can be further increased.
In the present embodiment, the outer surface of the taper portion is arranged at intervals with salient point 50, and adhesive tape is wound on the outside of taper portion.It is convex
Point 50 can increase frictional force to realize the firm of adhesive tape.
In addition, being originally also to be located between annular fill-in pad and elastic bulge loop that there is section in taper portion inner surface in embodiment
In the annular groove 60 of T-shaped, section can form the end of the enclosure space cooperation elasticity bulge loop 40 of vacuum in the annular groove 60 of T-shaped
Tighten and realizes end part seal.
If the utility model is open or relates to the parts or structural member of connection fastened to each other, except as otherwise sound
It is bright outer, it is fixedly connected and can be understood as：Connection (such as being connected using bolt or screw) can be removedly fixed, can also manage
Xie Wei：It is non-removable to be fixedly connected with (such as riveting, welding), certainly, connection fastened to each other or integral structure (
Such as manufactured using casting technique is integrally formed) replace (obviously can not be using except integrally formed technique).
In addition, being used to indicate position relationship or shape applied in above-mentioned any technical solution disclosed by the utility model
Term its meaning includes approximate with its, similar or close state or shape unless otherwise stated.
Either component provided by the utility model by multiple individual component parts either assembled, or
The separate part that integrally formed technique manufactures.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than limits it
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
