Fig. 3 is the partial enlarged view in Fig. 1 of the present invention at A；
Fig. 4 is elastic connecting component of the invention.
Specific embodiment
As shown in Figure 1, the present invention can be applicable to underground, it can also be used on ground, specifically include the first serving 1 and
Two servings, the second serving are set in the first serving 1, and between 1 inner wall of the first serving and the second serving outer wall
A hollow interlayer 2 is formed, fills inert gas in the hollow interlayer 2, can be used for preventing fires use；
There is one first protection chamber 8, the second serving includes two curved portions being oppositely arranged 12 in second serving
And two sealings 6 being oppositely arranged are spliced into a circular structure, the medial surface of curved portion 12 is provided with more than one
Clamping portion 9, a cable core 3 is respectively provided in clamping portion 9, cable core 3 is fixedly clamped by clamping portion 9, two sealings
Portion 6 is set to the top and bottom of two curved portions 12, and the outboard end of sealing 6 is respectively arranged with one group or more of elastic connection group
Part 11,11 one end of elastic connecting component connect the inner wall of the first serving 1, and the other end connects the outer wall of the second serving, sealing
It is linked and packed by buckle structure between portion 6 and the curved portion 12 of two sides, the two sides of two curved portions 12 are opposite respectively to be set
A contact portion 5 is set, be attracted between upper and lower contact portion 5 by magnetic structure and makes formation one among entire curved portion closed
Second protection chamber 22.
Wherein, two pieces of sealings 6 are all made of metal material and are made, and the curved portion 12 of two sides is all made of elastic material and is made.
Curved portion 12 must have good flexibility, so that can deform after extrusion not broken, curved portion is preferably with elastic gold
Belong to thin slice, such secondary protection intensity can be higher, naturally it is also possible to elastoplastic, elastic rubber etc. are selected, according to safety
Hierarchical selection uses.
One first stitching section 23 is respectively set in the two sides of sealing 6, and one second spelling is respectively set in the two sides of curved portion 12
Socket part 21, the first stitching section 23 and the splicing of the second stitching section 21 fasten, and contact portion 5 nestles up the setting of the first stitching section 23, such as Fig. 3
Shown, the opposite face of the first stitching section 23 each extends over one clamping part 24 of setting, and clamping part 24 limits the first stitching section 23 and makes
The first stitching section 23 is obtained to contact mutually with the second stitching section 21.When being pressurized or sheared at the top of whole cable, benefit
With more than one elastic connecting component sealing is pushed, during pushing, the curved portion of two sides is constantly deformed, finally
The contact portion of upper and lower side contacts with each other, and the magnetic structure on contact portion is attracted at this time, at this time the second protection chamber among curved portion
It is formed, each core wire is enclosed again to carry out second protection, when continuing to push, the first stitching section can be isolated out of clamping part
Come, the curved portion of two sides can independently get up at this time, form an independent structure and come the core wire inside second protection, such as Fig. 2
It is shown.
Wherein, as shown in figure 4, elastic connecting component 11 includes fixed connection shaft 113, telescopic rod 112 and spring
114, spring 114 is incorporated in the axis hole being fixedly connected inside axle sleeve 113, telescopic rod 112 be inserted in axis hole and with spring 114
A side end face contact.Elastic connecting component is there are two effect, and one is used as ejecting structure when pushing, and second is
For depressing when buffering and the first serving of connection and the second serving use, therefore in the design of the structure solves
Outer hanging problem, and solve the problems, such as ejection and buffering.
In the present embodiment, the medial surface middle position of curved portion 12 offers a triangle card slot 4, when curved portion bending
It closes Vee formation card slot 4 to be closed, the effect of triangle card slot is to make a concession to use for the bending after curved portion difference, reduces curved portion
Bounce after closure.
In the present embodiment, magnetic structure includes the magnet 7 that insertion is set in contact portion 5, and the contact portion 5 of upper and lower side is embedded
The opposite face of the magnet 7 entered is anisotropic face, and after the contact portion of upper and lower side contacts with each other, two blocks of magnet are attracted, and the suction-combining force is big
It, can be so that it keeps a fixed form, at this time after the contact portion of upper and lower side, which contacts, to be attracted in the elastic force of curved portion
It can consider third serving of the curved portion as cable core, in this case whole cable just has the ability of triple protection, greatly
Safety is increased greatly.
The beneficial effects of the present invention are: the one, present invention increases the anti-pressure ability of cable using the double-deck external and internal compositions, and
Inert gas is filled in hollow sandwich, even if there is fire source in outside, the inert gas that also can use in hollow sandwich is quick
Fire extinguishing, achievees the purpose that fire-retardant；
Two, the present invention can enable to two curved portion deformations, form two after the second serving reaches and squeezes the limit
A independent confining bed, by internal cable core, closed protective gets up and forms the second protection chamber again, in this way can be again
Cable is protected；
Three, it in common be pressurized, using elastic connecting component, is buffered as resistance to compression, while the second serving is hanging,
When first serving is pressurized, it will not be expressed to the second internal protective layer, would not also be had an impact to core wire, be particularly suitable for application
In exposed place.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be determined by the scope of protection defined in the claims.
