Specific embodiment
The invention will be further described with attached drawing combined with specific embodiments below, elaborates in the following description more
Details to facilitate a thorough understanding of the present invention, still the present invention obviously can be come with a variety of other modes different from this description it is real
Apply, those skilled in the art can without violating the connotation of the present invention according to practical situations make similar popularization,
It deduces, therefore should not be limited the scope of the invention with the content of this specific embodiment.
As shown in Figure 1, a kind of automobile-used semi-spiral optoelectronic composite cable of scouting of negative pressure rebound, comprising: optoelectronic composite cable 1 is born
The pressure stretch draw 2, reinforcing rib 3；
The optoelectronic composite cable 1 is helical form；
The negative pressure telescoping tube 2 is the cylindrical type of inner hollow, and wall surface is corrugated when initial, is fabricated from a flexible material；
As shown in Fig. 2, 2 both ends of negative pressure telescoping tube are mutually fixed with 1 both ends of optoelectronic composite cable respectively, negative pressure telescoping tube 2
1 spiral part of optoelectronic composite cable is wrapped up, 1 spiral part of optoelectronic composite cable is sealed；
The reinforcing rib 3 be annular shape, quantity be it is multiple, multiple reinforcing ribs 3 along straight line be arranged in 2 wall surface of negative pressure telescoping tube
On, and it is fixed on a bending place of negative pressure telescoping tube more than 2, negative pressure telescoping tube 2 is supported by multiple reinforcing ribs 3, prevents from bearing
The pressure stretch draw 2 is influenced compressive deformation after the stretch, by negative pressure；
As shown in figure 3, pulling optoelectronic composite cable 1 to side, optoelectronic composite cable 1 drives negative pressure telescoping tube 2 to be unfolded, due to negative
2 inner air content of the pressure stretch draw is constant, but space increases, and allows inside negative pressure telescoping tube 2 and forms negative pressure, the strength that side pulls
When disappearance, by the power of 2 internal negative pressure of negative pressure telescoping tube, negative pressure telescoping tube 2 rebounds, 2 air pressure inside of negative pressure telescoping tube after rebound
It is identical as outside.
Preferably, as an embodiment, as shown in figure 4, the spiral part of the optoelectronic composite cable 1 be it is multiple,
It is respectively arranged with negative pressure telescoping tube 2 on the spire of multiple optoelectronic composite cables 1, is on the one hand avoided when stretching negative pressure telescoping tube 2,
The power of negative pressure is excessive, is not easy to stretch optoelectronic composite cable 1, on the other hand avoids stretching 2 breakage of negative pressure telescoping tube, can not form negative pressure.
Preferably, as an embodiment, it is connected with dowel between the reinforcing rib 3 and optoelectronic composite cable 1, led to
Dowel is crossed by optoelectronic composite cable 1 and 2 synchro-draw of negative pressure telescoping tube, prevents optoelectronic composite cable 1 in contraction process, generate with
The winding in meaning direction, is not easy to stretch next time, while negative pressure telescoping tube 2 being avoided to be caught in optoelectronic composite cable 1.
Preferably, as an embodiment, the promising gas phase silica gel of the negative pressure telescoping tube 2 is made, gas phase silica gel with
Common silica gel rubber compound is compared.Gas phase silica gel tensile strength is better than mixing silica gel, and gas phase silica gel tensile strength is in 700%-800%
Between will not produce fracture, and common melting silicone rubber tensile strength is only between 300%-400%, long in negative pressure telescoping tube 2
In the stretching and springback process of phase, using gas phase silica gel, the service life of negative pressure telescoping tube 2 can be prolonged, preventing it, deformation occurs.
Preferably, as an embodiment, the negative pressure telescoping tube 2 is identical as the tensile elongation of optoelectronic composite cable 1,
1 length of optoelectronic composite cable is limited when negative pressure telescoping tube 2 being avoided to stretch.
Preferably, as an embodiment, the diameter of the two neighboring reinforcing rib 3, size interval distribution, negative
When the pressure stretch draw 2 is sprung back, the shape of negative pressure telescoping tube 2 is limited by two neighboring reinforcing rib 3 of different sizes, negative pressure is avoided to stretch
2 wall surface of the draw inwardly sticks into optoelectronic composite cable 1 or 2 wall surface of negative pressure telescoping tube is scratched with exterior materials formation outward.
Working principle of the present invention:
Optoelectronic composite cable 1 is pulled to side first, optoelectronic composite cable 1 drives negative pressure telescoping tube 2 to be unfolded, since negative pressure is flexible
2 inner air content of pipe is constant, but space increases, and allows inside negative pressure telescoping tube 2 and forms negative pressure, and the strength that side pulls disappears
When, by the power of 2 internal negative pressure of negative pressure telescoping tube, negative pressure telescoping tube 2 rebounds, after rebound 2 air pressure inside of negative pressure telescoping tube with
When external identical, stop rebound, optoelectronic composite cable 1 and negative pressure telescoping tube 2 become original state again.
