The utility model discloses a sealing protection device for animal decoction pieces and medicinal materials, which is characterized in that support plates are fixedly mounted in the middle and at the bottom of the inside of a storage box, moving plates are movably mounted at the top ends of the two support plates, sealing boxes are fixedly mounted at the top ends of the two moving plates, and medicine boxes are movably embedded in the sealing boxes; a guide sleeve is fixedly installed in the middle of the top end of the sealing box, an adjusting screw rod is installed in the middle of the guide sleeve, the top end of the adjusting screw rod is fixedly connected with an operation round block, and the bottom end of the adjusting screw rod is fixedly connected with a connecting disc. The stability of placing medicinal materials in the medicine box is improved, the situation that the medicinal materials shake in the medicine box and are damaged in the transporting and moving process is avoided, meanwhile, the soft hair cushion is soft and small in pressing strength and prevents the medicinal materials from being directly pressed and smashed, the moving plate can slide along the supporting plate, and great convenience is provided for taking out the medicinal materials.

This application provides a thermal insulation foam, a method for preparing the thermal insulation foam, and a refrigeration device. The thermal insulation foam has a honeycomb structure with multiple honeycomb pores penetrating the foam along a first direction parallel to the centerline of the honeycomb pores. The density of the thermal insulation foam decreases along a second direction perpendicular to the first direction. This allows for the simultaneous optimization of low density and high compressive strength in the thermal insulation foam.
