Preferably, the roll wheel assembly includes mounting base, shaft and roller body, the shaft and the roller body
It is rotatedly connected, the both ends of the shaft are connected with the mounting base, and one end of the spring pushes against the lateral wall of the elastic layer,
The other end of the spring pushes against a side end face of the mounting base away from the shaft.
Compared with prior art, the utility model tool has the advantage that：The utility model proposes prefabricated direct-buried insulation
Guan Zhong, interior tube layer, heat insulation layer, internally reflective layer, insulating layer and outer reflective layer are provided outside elastic layer, so in interior tube layer, absolutely
After thermosphere, internally reflective layer, insulating layer and outer reflective layer are heated and different degrees of expansion occur, elastic layer also can be swollen accordingly
It is swollen, while elastic layer can also compress the gap between interior tube layer, heat insulation layer, internally reflective layer, insulating layer and outer reflective layer, prevent
Amount of heat is conducted by the gap to lose, and extension type rolling support can be in interior tube layer, heat insulation layer, internal reflection
Layer, insulating layer and when outer reflective layer expanded by heating, extend accordingly, not only avoid rolling support from damaging, but avoid rolling support with
The part of remaining insulating tube contacted produces gap.Therefore, compared with prior art, the utility model, which has, prevents that heat is big
The advantages of amount loss.
