It is good to cover effect, performance is stablized.
To achieve the above object, the utility model is realized according to following technical scheme：
A kind of cable protection casing, the cable protection sleeve body are internally provided with cable and place passage, described sleeve pipe sheet
The cross section of body is circular ring shape, and described sleeve pipe body is equipped with protective layer one, buffering area, protective layer two successively from inside to outside；It is described
At least three equally distributed elastic supports in a circumferential direction are equipped with buffering area；The elastic support both ends connect respectively
It is connected on protective layer one and protective layer two.
Cable protective sleeve pipe described in the utility model has the structure of three-layer protection, and excellent pressure-proof and snap-resistent performance,
And cable is wrapped in inside protection sleeve pipe by impact resistance, the protective layer one, the protective layer two has preferable shielding
Effect, performance are stablized, and the elastic support can play good cushioning effect, when cable produced by foreign impacts it is larger
During motional inertia, using elastic support draw high and contractility, infringement of the impact to cable is offset, when cable is by the external world
During extruding on single direction, elastic support eliminates influence of the extraneous factor to cable by adjusting the compression degree of itself.
Preferably, the protective layer one is made of elastic material, diametrically with good telescopicing performance, to thickness journey
Degree is different, the irregular cable in cross section can play preferably constraint and fixation, prevent cable move caused by friction and
Electric loss.
The elastic support includes elastic fulcrum bar and spring, and when cable runs into serious extruding, elastic fulcrum bar is being protected
Good supporting role is played between sheath one and protective layer two, effectively prevents casing deformation, eliminates ambient pressure to cable
Infringement；When cable produces motional inertia by foreign impacts power, the supporting role of elastic fulcrum bar and the elasticity of spring are utilized
Flexible ability moves cable small range inside protection sleeve pipe, gradually dissolves influence of the impact force to cable.
Bullet recovery rate≤85% of the elastic support, when protecting cable to be caused deformation by external force, eliminates external force
Cable protection casing can recover reset condition rapidly.
Preferably, the buffering area is divided into multiple chambers by least three elastic supports, is equipped with each chamber
Air cushion, the air cushion maximum volume are slightly less than chamber volume.The air cushion has good elasticity, when cable is run into compared with strong pressure
Or greater impact masterpiece used time, the air cushion can utilize natural resiliency, external force is converted into elastic force, eliminates external force to cable
Influence.
The protective layer one and cable place the side that passage is connected and are coated with insulating materials, the insulating materials have compared with
High insulation resistance and compressive resistance, the problems such as effectively avoiding leaking electricity and puncturing；The outside of protective layer two is coated with resistance to height
Warm erosion shield, can preferably obstruct infringement of the external environment to cable.
Compared with prior art, the utility model beneficial effect is：
1. cable protective sleeve pipe described in the utility model has the structure of three-layer protection, pliability is good, to various layings
The cable of form can play preferable protective effect, have good shield effectiveness, and performance is stablized；
2. protective layer one described in the utility model is made of elastic material, irregular to fineness difference, cross section
Cable can play preferably constraint and fixation, eliminate cable movement caused by friction and electric loss；
3. cable protective sleeve pipe described in the utility model has stronger pressure-proof and snap-resistent performance, the line being laid with for ground
Cable, is running into sinking of ground or soil erosion etc. because of the single direction stand under load there is a situation where pipe sleeve overbending, described slow
Rushing area can play a supporting role and can eliminate infringement of the external force to cable；
4. cable protective sleeve pipe described in the utility model has good impact resistance, met for the cable being laid with the air
When impacting generation motional inertia to strong wind, the elastic force that power-conversion is elastic support can be eliminated impact by the buffering area
Influence of the power to cable；
