Raised 131 are pressed into voice announcer switch 31, wherein, described raised 131 with the cantilever 13 can be integrally formed, can also
By pasting, screw fix etc. mode combine connection.Cantilever 13 is made using elastomeric material, when the lid 20 for opening control device
When, the cantilever 13 is deformed upon under the pressure of the extension 21, through the triggering voice announcer switch of the breach 17
31.When the lid 20 is closed, lid 20 is applied to the external force of cantilever 13 can disappear, and voice announcer switch 31 is closed.
In the present embodiment other specific implementations, the shape and material to the cantilever 13, and it is fixed on the side wall of the groove 11
On particular location, do not limit, as long as it can deform upon to press under external force and trigger voice announcer
Switch 31.
With continued reference to shown in Fig. 4, Fig. 5, in one concrete implementation mode of the present embodiment, the cantilever 13 and groove floor
16 the groove floor projection in the plane it is misaligned, cantilever 13 can under pressure to the voice announcer
The direction that switch 31 is located deforms upon, and presses and trigger the voice announcer switch 31.In the present embodiment, another is concrete
Implementation in, the projection of the cantilever 13 and groove floor 16 in the plane that the groove floor is located at least partly is weighed
Close, and there is gap between the bottom surface 16 of the cantilever 13 and the groove 11 so that cantilever 13 occurs under pressure shape
During change, with enough deformation spaces, the voice announcer switch 31 is pressed and triggered.
In another not shown concrete implementation mode of the present embodiment, cantilever is set on the side wall of the groove,
The cantilever extends from the side wall to the direction away from the side wall, and voice announcer switch is located in the groove, when beating
When opening box body, the extension pressing cantilever of lid, cantilever is deformed upon under the pressure of extension, so as to trigger voice announcer
Switch.Likewise, when box body is closed, extension is applied to the external force of cantilever and disappears, and voice announcer switch is closed.
In embodiments of the present invention, the fixture block of the correspondence cantilever is formed with the extension of the lid.Fig. 6 is this
The structural representation of bright embodiment control device lid, with reference to shown in Fig. 3 to Fig. 6, is provided with the extension 21 of lid 20
Be projected on the fixture block 22 of the extension 21, the fixture block 22 extension 21 free end to the side away from the extension 21
To extension, the position of the fixture block 22 is corresponding with the cantilever 13, when the lid 20 is in open mode, the fixture block
There is shape in the 22 pressings cantilever 13, direction of the cantilever 13 to voice announcer switch 31 under the compressing of fixture block 22
Become, press and trigger the voice announcer switch 31.The number of the fixture block 22 can be arranged as required to, in the present embodiment
The number of fixture block 22 is two so that the stress of cantilever 13 is more balanced, stable.In other embodiments, the fixture block 22 is individual
Number and shape can be set as needed.
With continued reference to Fig. 5 to Fig. 7, in the present embodiment the first paragraph 132 higher than groove floor of the cantilever 13 with it is recessed
Limiting between the side wall of groove 11 has draw-in groove 133, and the lid 20 opens to fixture block during specified location 22 pieces and is located at the draw-in groove
In 133.After the lid 20 is fully open, the fixture block 22 is fastened in the draw-in groove 133, the fixture block 22 and draw-in groove
133 position limiting structures for constituting so that the voice announcer switch 31 is in closure state in cantilever 13 by pressure always.Enter
Position limiting structure described in one step plays fixation after lid 20 is opened to lid 20, and without one hands of operator lid is responsible for
20, another handss pressing operation button 40 facilitates operator.
In the present embodiment, the fixture block 22 is contacted with the cantilever 13 for face.With reference to Fig. 7, the fixture block 22 is pressed into outstanding
The press surface beveling of arm 13, increases contact area of the fixture block 22 when cantilever 13 is pressed, and the He of fixture block 22 is avoided as far as possible
Cantilever 13 is damaged.
In the present embodiment, the voice announcer 30 can be located in box body 20 near voice announcer switch, it is also possible to set
Put in the interior other positions of magnetic resonance imaging.In addition to reminding the switch of operator's tray interior for drop field switch, may be used also
To remind operator to make sure to keep in mind lid 20 resets when lid 20 are opened in order to avoid may draw when prompting measure is lacked
The false triggering for rising.
The present embodiment exemplarily only describes the triggering device of several voice announcers, does not constitute and the present embodiment is touched
The restriction of transmitting apparatus.
Fig. 8 is structural representation of the control device of another embodiment of the present invention when box body is opened, with reference to shown in Fig. 8,
In an alternative embodiment of the invention, the control button 40 is the drop field switch in magnetic resonance system, is provided with the edge
Aperture 50, the aperture 50 can be made up of LED, and when lid 20 is opened, the circuit of the LED is switched on, LED
Light bar can be luminous, visually reminds operator to operate with caution.
Further, in the present embodiment, with reference to shown in Fig. 1, Fig. 2, the box body 10 is removed with the corresponding one side of the lid 20
With the marginal position beyond the corresponding part of the lid 20, some buttons 15 are set, button 15 can be included for controlling magnetic
Resonator system system boot, shutdown, standby button, can also be included for releasing the button reported to the police, the number and work(of button
Can be set according to the demand of operator.
The present embodiment is integrally disposed in field switch is dropped in the control device of magnetic resonance system, without the need for being separately provided one solely
Vertical switch, improves device integration, also saves resource.It is provided for reminding operator's control device in control device
Internal switch for drop field switch voice announcer, it is to avoid because operator do not know the purposes or unclear that switchs
The sign of drop field switch and the false triggering that causes, improve the safety of system.The cantilever of the present embodiment carries limit function, when
When the lid of control device is opened, due to the limit function of cantilever, make lid all the time in the position of triggering voice announcer, language
Sound broadcast device persistently plays voice messaging, reminds the lid of the timely shutoff control unit of operator.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
