Quick connecting structure for load box displacement wire pipe

The invention relates to a wire pipe quick installation connecting part for testing the relative displacement of upper and lower bottom plates of a load box, and belongs to the field of civil engineering. A quick connecting structure for a load box displacement wire pipe comprises the displacement wire pipe, limiting parts and connecting parts; the displacement wire pipe serves as a protection pipe of a displacement wire and isolates concrete of the displacement wire pipe; the limiting parts comprise an upper limiting part and a lower limiting part which are respectively used as fixed ends ofan upper displacement wire and a lower displacement wire; the connecting parts comprise an upper connecting part and a lower connecting part; one end of the upper connecting part and one end of the lower connecting part are inserted into the two ends of the displacement wire pipe respectively and limited with the displacement wire pipe through the limiting parts; the other end of the upper connecting part is connected wit
