Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment：A kind of portable fiber-optic heats test device, its structure as Figure 1-4, including carrying case 12 with plus
There is the common component such as battery, inverter, charger, temperature controller in the two parts of hot rod 13, carrying case 12, and with temperature
Indicate, voltage indicates screen and relevant cables interface, box house construction is not discussed in detail here.
Heating pole 13 includes that shell, heat shield, conducting strip 9 are constituted.The upper and lower two parts of described shell point：Upper shell 5 with
Lower house 1, described heat shield also divides upper and lower two parts：Upper heat shield 4 and lower heat shield 2.Described upper shell 5 and lower house
1 is connected by hinge 3, is easy to raise and is not separated.Hinge 3 is arranged on upper shell 5 and lower house 1 by screw 11.
Fastened with magic strap 6 after upper shell 5 and the closing lid of lower house 1, both ensure that upper-lower casing closes tight, again convenient dismounting.
Upper-lower casing closes tight in order to the heat that heating tape 8 produces is not distributed not go out, and allows temperature probe 7, the heating tape 8, optical fiber of inside
The temperature of 10 threes reach balance and it is consistent.
Described upper shell 5 and the profile of lower house 1, take circular or square or other shapes all can, this patent diagram is used
Circle is described.The material of shell with the light carbon fibre material or other plastic materials for having intensity, all serve it is light, do not lead
Hot, nonconducting effect.
What described enclosure up and down was close to is upper and lower heat shield, and both use gluing knot, and the inside of lower heat shield 2 is to lead
Backing 9, conducting strip 9 and the lower gluing knot of heat shield 2.The inside of upper heat shield 4 is temperature probe 7 and heating tape 8, and both also use
Glue is bonded together with upper heat shield 4.
Described adhesive glue must high-temperature plastic.
The material of described conducting strip 9 is the good conductor of heat, all may be used with copper sheet, aluminium flake.Sufficiently by the temperature of heating tape 8
Degree is transmitted to optical fiber 10 up.
