Abstract: An off road vehicle has an air heater with right and left shells surrounding and supporting a core, with the right and left shells connected by screws extending through ears on one of the shells into bosses on the other shell. Dual air control plates are mounted in the shell on a shaft for pivoting movement. An actuator is linked to the shaft by a swing arm with a guide pin riding in an arced slot of a drive plate rotationally secured to the shaft. The right and left shells are secured to the vehicle using a resilient compressible grommet, with a bushing extending through the grommet and a bolt extending through the bushing and attached into the frame.

Abstract: The present invention discloses a polyvinyl chloride floor with high stain resistance and easy cleaning functions. The polyvinyl chloride floor includes a polyvinyl chloride floor layer and a stain-resistant surface layer, wherein the stain-resistant surface layer is formed by co-extruding an outer protective layer, a functional layer and an adhesive layer; the outer protective layer is a fluorine-containing polymer; the functional layer is formed by mixing the fluorine-containing polymer, a hot melt adhesive and functional aids; the adhesive layer is formed by mixing the fluorine-containing polymer and the hot melt adhesive; and the stain-resistant surface layer is in hot-melt adhesion connection with the polyvinyl chloride floor layer through the adhesive layer. The present invention has advantages of green environmental protection, high wear resistance, water resistance, moisture resistance, bacterial resistance, stain resistance and difficulty in leaving traces.
