Description
Technical field
The present invention relates to shield technology field, more particularly, to a kind of nuclear magnetic resonance equipment machine for being used for medical field
The high-performance knife in room inserts formula list fan vertical hinged door.
Background technology
Shield door is mainly used in the nuclear magnetic resonance equipment computer room of medical field, and effect is to intercept external electromagnetic signal to equipment
The influence of image quality.With the increase of the high field shield market demand, conventional shield door is crack between a door and its frame mask pattern, therefore universal shield
Door is difficult to meet requirement of the High-Field MR equipment such as each producer 4.7T, 7T, 9.4T to shield effectiveness.
Currently in order to the shield effectiveness of shield door is improved, abutting contact structure between generally use door knife and beryllium copper reed,
As shown in figure 11, including bracket 20 and door knife 10, the door knife 10 on door (not shown) insert bracket 20 and (are arranged on screen
Cover on body) beryllium copper reed 21,23 between, and beryllium copper reed 21,23 insert respectively in advance bar-shaped shielding gasket 22,
24, because shielding gasket 22,24 is flexible, so as to when door knife inserts beryllium copper reed, be biased to beryllium copper reed so that beryllium
Copper reed is more close to a knife, and so fit clearance between them substantially reduces, so as to effectively prevent electromagnetic wave
Leakage, improve shield effectiveness, however, also bring Cat-in resisting force increase the problem of, this can cause shield door be difficult to close and
Open, very big inconvenience is brought to operator.
Chinese patent CN2008201184271 discloses a kind of electromagnetic shield door, including the plug-in unit being fixed in door body
(100) include door knife (110), door bracket (120) with the socket (200) that is fixed on shield, the plug-in unit and be arranged on

Fan body screen layer is closely connected, and effectively improves shield effectiveness, is effectively fixed reed 41 by the hook design of snak link 42
On spring base 43, when door knife 3 inserts spring part 4, now reed 41 can inside compression deflection, now by conducting foam come
Prevent reed 41 from deforming, and conducting foam material itself is very light, the electrostatic that can have the performance leading products of electromagnetic shielding is prevented
Shield performance has concurrently permanently, and material is gently so its surface impedance ability just reduces, the features such as to ambient humidity no dependence.This reality
Fixed effect can also be played by applying conducting foam in example and preferably being contacted with reed 41;Above-mentioned design passes through snak link and conducting foam
To realize that the both ends of reed 41 are fixed and anti-deformation, while do not increase the resistance of insertion, it is convenient to ensure that shield door opens and closes,
And it is simple in construction, it is not high to requirement on machining accuracy, while the detachable of beryllium copper reed can also be realized, it is easily changed and ties up
Repair.
In order to coordinate a knife 3 to design, the closing mode of shield door is closed the present embodiment using Wedge type, it is ensured that door knife 3 with
The good contact of reed.Further the present embodiment Wedge type uses concealed two point wedge retaining mechanism, and operation principle is as follows:
Handle is pressed, is allowed to push, drives sliding bar to be moved upwards along the wedge slide block guide groove on doorframe by connecting linkage,
And door leaf is closed with Wedge type, locked, it is ensured that the good contact of door knife 3 and reed.This mechanism in door leaf in the closed state,
Sliding bar and wedge slide block all would fit snugly within a knife 3, and comparing exposed pattern does not influence overall appearance, and door leaf open mode only has
Wedge slide block is visible.
The present embodiment doorframe uses magnetism-free stainless steel bending part, and with argon arc welding full weld into framework, increase is " double in framework
Spring " spring part structure, interworking use is carried out with the door knife of door leaf, realizes that crack between a door and its frame signal is efficiently intercepted, framework is reserved rotating shaft and fixed
Space, framework are provided with the wedge slide block of concealed two point wedge retaining mechanism.
The present embodiment door leaf core structure designs add acoustic material packing space, soundproof effect can be lifted 30dB with
On, door leaf links rotating shaft with doorframe and adds high intensity, high life needle-type bearing conduct, substantially increases the longevity of shield door
Life.
The present embodiment rotating shaft mechanism uses two groups of rotating shafts, and doorframe rotating shaft puts down face and mainly plays a part of to support door leaf, such a
Door leaf and doorframe can be installed separately by structure, first filled doorframe and are fixed to civil engineering wall hole, then by door leaf by rotating shaft coordinate installation and
In doorframe axle bed, so it is easy to dismounting to repair, reduces difficulty and labor intensity when installing.
The present embodiment is used to adjust gap above and below door leaf by the adjustable locking nut on door leaf axle bed, avoids using process
Gap is uneven above and below causing because of door leaf sinking, so that door knife and switch jaw contact are bad, causes signal to reveal.
The present embodiment is pressed into needle-type bearing in axle bed, can reduce rotating shaft and the friction of axle bed in the course of the work, make
Door leaf operating is more flexible, effectively to store lithium base grease, reduces friction of motion, and fit precision is high, ensures that door leaf is steady, suitable
Freely operation, noiseless, improve the service life of door.
The slotting formula list fan shielding vertical hinged door shielding efficiency height of the present embodiment high-performance knife, stable performance, folding with convenience, operation are put down
Steady noiseless, performance in 40~600MHz spectrum masks efficiency up to more than 100dB, suitable for the high field intensity MR equipment such as more than 7T
Screened room.
Embodiment 2
As shown in Figure 10, the present embodiment is substantially the same manner as Example 1, and difference is, door leaf 2 is provided with two door knives 3, doorframe
1 is provided with two spring parts 4 used with two interworkings of door knife 3, and compared with prior art, the present embodiment door leaf 2 and doorframe 1 are all reserved
There is the space of composite gate knife 3, if it is necessary, increase " spring structure of double-pole four ", sustainable raising shield effectiveness.
Wherein, the present embodiment should not be limited to using two door knives and corresponding spring part Yus two, can be according to reality
Situation sets two or more.
