Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Referring to figs. 1 to shown in Fig. 3, the structure of shielding case includes ontology 1, upper cover 2, and upper cover 2 is provided with external screw thread, ontology 1
Top is provided with internal screw thread, and upper cover 2 is arranged in the top of ontology 1, is connected with each other using helicitic texture, the externally threaded bottom of upper cover 2
Portion is provided with temperature sensor 23, and upper outer side of lid is equipped with temperature indicator 22, and 2 inner tip of upper cover is equipped with cooling piece, this
Body 1 is in cylindrical structure, the intermediate hollow out of the ontology 1 and is once provided with three layers of shielded layer and shell 7 from inside to outside, and first
Layer is protective layer 4, and the second layer is insulating layer 5, and third layer is metal layer 6, and the outside of protective layer 4, metal layer is arranged in insulating layer 5
6 are arranged in the outside of insulating layer 5, and protective layer 4 is one layer of annular Moisture-absorption sheet, apply around annular Moisture-absorption sheet and are wrapped with iron powder, protective layer
4 are used to the air around dry, so that metal layer 6 is not easy oxidation by air, the service life of shielding case are increased, due to using
Multi-layer isolation layer also strengthens the shield effectiveness of shielding case, is provided with shell 7 on the outside of metal layer 6, shell 7 be by left housing and
Right housing composition, left housing and right housing two sides are respectively arranged with fixed block 71, and fixed block 71 is connected by fixing screws 72, this
External screw thread 74 is provided with below body 1, ontology 1 can be positioned below pedestal 3, and the pedestal 3 is provided with internal screw thread, 1 He of ontology
Pedestal 3 is connected through a screw thread.It is too long such as to encounter equipment, in the case that shielding case length is inadequate, multiple ontologies 1 can be used and cooperate
