Compared with prior art, cable of the invention has good resistance to compression effect very outstanding, sheath and metal cable core
Between filled with liquid lubricant layer, this layer of liquid lubricant layer makes sheath with metal cable core not in contact with when external force is axially drawn
When pulling cable, liquid lubricant layer make sheath cannot contacting metal cable core, therefore metal cable core will not with sheath together receive axle
Xiang Li, therefore, cable anti-axial tensile of the invention it is very capable, when external force extruded cable, sheath is compressed in metal
On cable core, although the two is contacted, liquid lubricant layer plays a part of lubrication in centre, can greatly reduce sheath with gold
Frictional force between category cable core, sheath axial extensional under extruding force " will not also grab " and live metal cable core and deform together, have
The sheath that effect prevents metal cable core from being deformed is broken.Cable body of the present invention is provided with every pad is drawn, and is padded as inside is filled with every drawing
The elastic pouch of liquid lubricant, is coated with cable top every drawing pad, and the top of all cables is covered, and is made cable and is set
Put every the obturator isolation for drawing pad top.It is that the preliminary obturator by cable and outside is separated every the effect of drawing pad, due to
Obturator volume is larger, and pulling force is big during deformation, therefore sets every the obturator deformation pulling force for drawing pad first to offset cable top,
Ensure that metal cable core will not be broken.It is more order of magnitude greater than liquid lubricant layer every the liquid volume in drawing pad, and cable is often
Can be blocked as needed, therefore, the present invention will be arranged to one section one section every drawing pad, and set mark every section of truncated position,
Convenient construction personnel block cable in place.

Specific embodiment
Embodiments of the invention are described in further detail below in conjunction with accompanying drawing.
A kind of cable with resistance to compression function of the invention, including cable body 1, cable body 1 include armor 11 with
And the several cables 2 being placed in armor 1, it is characterized in that：The bottom of armor 11 is in flat, and the bottom of the inner chamber of armor 11 sets
Flexible bottom 3 is equipped with, the quantity seat slot 21 suitable with the quantity of cable 2 is provided with flexible bottom 3, cable 2 is fixed on seat slot 21
In, the sheath 22 that cable 2 includes metal cable core 23 and is wrapped in outside metal cable core 23, between sheath 22 and metal cable core 23
Filled with liquid lubricant layer 24, liquid lubricant layer 24 makes sheath 22 with metal cable core 23 not in contact with cable body 1 is set
Have every drawing pad 4, every drawing pad 4 to be the internal elastic pouch filled with liquid lubricant, be coated with the top of cable 2 every drawing pad 4, and will
The top of all cables 2 covers, and makes cable 2 and is arranged on every drawing the obturator 5 on the top of pad 4 to isolate, and obturator 5 fills armouring
The aperture sections of 11 inner chamber of layer enrich cable body 1, and a segment distance is provided with a circle knot in the axial direction every pad 4 is drawn
Ring 41 is pricked, ligation ring 41 will can be mutually separated and sealed every the liquid lubricant in drawing pad 4.
In embodiment, the material of sheath 22 is plastics.
In embodiment, liquid lubricant layer 24 is filled with the plastic bag structure of liquid lubricant, and the polybag for inside
The material of structure is identical with the material of sheath 22, and the outside of liquid lubricant layer 24 is combined together with sheath 22.
In embodiment, wire netting 13 is filled with the flat bottom 12 of armor 11, wire netting 13 makes flat bottom 12 hard
Arc top 14 of the degree higher than armor 11.
In embodiment, labeled slots 15 are provided with outside armor 11, the position of labeled slots 15 is relative with the position of ligation ring 41
Should, labeled slots 15 are used to indicate ligation ring 41 position.
