The inner peripheral surface of adjacent two flexible ring bodies is connected in monomer, and this structure makes protective case have good retractility and flexibility,
The a degree of differential settlement in ground is can adapt to, protective case is made to follow surface subsidence and stretch and be bent, avoids the occurrence of guarantor
Happening for sheath damage, has achieved the purpose that preferably to protect power cable.
2nd, each flexible ring body is equipped with the first bending section and the second bending section, and such a structure increases the stretching surface of protective case
Product and bending degree further improve the extensibility and flexibility of protective case；First bending section and the bending of the second bending section
Work as protective case on the contrary, the first corresponding bending section of two flexible ring bodies and the second bending section are adapted in flexible unit in direction
When being compressed, flexible ring body can be made to be close together, so as to further improve the compressibility of protective case.
3rd, body further includes straight pipe, and straight pipe is connected and is arranged at intervals with compliant section, and straight pipe cannot be bent and stretch
Contracting, therefore the plastic deformation of protective case can be reduced, make protective case that there is certain crushing resistance, and avoid protective case transition curved
It is bent.
4th, the junction of the peripheral surface of two flexible ring bodies is the first arc in flexible unit, and this structure, which is conducive to increase, protects
The crushing resistance of sheath.
5th, the junction of circumferential surface is the second arc in adjacent two flexible rings body in adjacent two flexible unit, and this structure makes
Power cable reduces the resistance inside protective case during being put into protective case, so as to which power cable be made smoothly to be put into guarantor
Sheath.

Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this hair
It is bright to be described in detail.
Embodiment 1
As depicted in figs. 1 and 2, the present invention includes body 1, and body 1 is made of compliant section 2.Compliant section 2 includes several along its axial direction
The flexible ring body 2.1 of arrangement, flexible ring body 2.1 are circular ring shape, and the hollow hole of flexible ring body 2.1 forms cable passage 2.2, adjacent
Two flexible ring bodies 2.1 form flexible units 2.3, and the peripheral surface of two flexible ring bodies 2.1 is connected in flexible unit 2.3, and adjacent two is soft
Property monomer 2.3 in the inner peripheral surfaces of adjacent two flexible ring bodies 2.1 be connected.Each flexibility ring body 2.1 is equipped with 2.4 He of the first bending section
The bending direction of second bending section 2.5, the first bending section 2.4 and the second bending section 2.5 is on the contrary, two flexible in flexible unit 2.3
