Abstract
The utility model discloses a shielding emergency exits, including door frame, door plant, the trompil of door plant middle part for installation detachable emergency exits, emergency exits be provided with the hasp towards screened room one side, it is fixed with the door plant that emergency exits pass through the hasp. The utility model discloses a nuclear magnetic resonance screened room is applied to to emergency exits, and the reed is pasted all around to emergency exits, in the lock brass layer extrusion of jail back reed and the inboard parcel of shield door trompil of emergency exits, can reach and prevents that radiofrequency signal from leaking the effect. When indoor causing danger, conveniently flee.
Description
Technical field
The utility model relates to a kind of escape, particularly relates to a kind of shielding escape being applicable to nuclear magnetic resonance screened room.
Background technology
Nuclear magnetic resonance screened room is a special environment, because superconducting magnetic resonance is when quench under this environment, in magnetic resonance equipment, liquid helium can with the ratio transient evaporation of 1:700, screened room internal gas pressure is caused to increase, if now shield door opens in screened room, the inside and outside huge atmospheric pressure missionary society of screened room causes manpower to open shield door.
Summary of the invention
For the problems referred to above, the utility model proposes a kind of shielding escape, these escape not only will solve the problem of escape, also will ensure the shield effectiveness of screened room.
The utility model is achieved by the following technical solution: a kind of shielding escape, comprise doorframe, door-plate, perforate in the middle part of described door-plate, for installing dismountable escape, described escape are provided with snap close towards screened room side, and escape are fixed by snap close and door-plate.
Further, the surrounding parcel layer of brass of perforate in the middle part of described door-plate.
Further, described escape surrounding parcel layer of brass.
Further, the layer of brass of described escape surrounding is also provided with reed, reed and door-plate extrude lower deformable and are tightly connected in door-plate.
The utility model compared to existing technology, has following beneficial effect: the utility model escape surrounding pastes reed, and the layer of brass wrapped up inside escape lock the rear reed in jail and shield door perforate extrudes, and can reach and prevent radio frequency signal leakage effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model partial front elevation view.
Fig. 3 is the utility model partial rear view.
Wherein: 1-escape, 2-snap close, 3-reed, 4-layer of brass.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure.A kind of shielding escape, comprise doorframe, door-plate, perforate in the middle part of described door-plate, for installing dismountable escape 1, described escape 1 are provided with snap close 2 towards screened room side, and escape 1 are fixed by snap close 2 and door-plate.
Further, the surrounding parcel layer of brass 4 of perforate in the middle part of described door-plate.
Further, described escape 1 surrounding parcel layer of brass 4.
Further, the layer of brass 4 of described escape 1 surrounding is also provided with reed 3, reed 3 and door-plate extrude lower deformable and are tightly connected in door-plate.
During use, when there is quench or other contingencies in nuclear magnetic resonance screened room, the personnel being positioned at nuclear magnetic resonance screened room can by opening the snap close 2 on escape 1, escape 1 are outwards firmly released, whole escape 1 are departed from former shield door, while forming escape space, makes inside and outside differential pressure reach balance.Personnel in such nuclear magnetic resonance screened room just can smooth escape, and the personnel being also convenient to outside enter indoor rescue.
