Specific embodiment
It is described in further detail below in conjunction with most preferred embodiment shown in attached drawing.
As shown in Figure 1, mini shielding castle of the invention specifically includes that shield shell 1 and is located at the shielding case
Test equipment and its circuit 2 in body 1.Wherein, the bottom of the shield shell 1 is fixed in rack 6,6 bottom of rack peace
Equipped with several slider rollers 3, being convenient to for being moved in entire laboratory in this way needs place to be tested, such as office, reality
Room, even common office building, premises use are tested, very flexibly and easily.As shown in Figures 2 and 3, on which includes:
Shell 11, lower case 12 and switching mechanism 13.Wherein, the lower case 12 is fixed part, and the upper housing 11 is removable
Dynamic part, the section of the two can be rectangle, circle, diamond shape etc. but be not limited to the above shape, and it is irregular to be also possible to other
Shape.The switching mechanism 13 then connects the upper housing 11 and lower case 12, and drives lower upper housing 11 relative to lower case 12
Oscilaltion campaign is carried out to open or close shield shell 1.
When switching mechanism 13 drives upper housing 11 to move up, open state as shown in Figure 2, at this time, it is convenient to will be to
The product of test is put into or takes out；And when switching mechanism 13 drives upper housing 11 to move down in place, as shown in figure 3, upper housing 11
Just closed together with lower case 12, the shielding case body that upper-lower casing forms an entirety can in this way when carrying out radio frequency testing
With shielding case body external electromagnetic waves, interference of the outfield electromagnetic wave to box house test equipment is reduced, to obtain more accurately
Test data, while also can prevent internal electromagenetic wave radiation from leaking.
Chain drive, rack-and-pinion, hydraulic push rod, lead screw/screw drive, synchronous belt can be used in the switching mechanism 13
The common kinds of drive such as transmission drive the upper housing 11 to move up and down.The mode that this lifting is opened is opened relative to traditional side
The opening ways of door or covering type, mini shielding castle of the invention can allow entire shell to be opened, facilitate operation, and can reach
To the index performance of similar product, belong to pioneering.
As shown in Figure 1 and Figure 4, the switching mechanism 13 includes: transmission mechanism and its power transmission member 131, connector
132 and vertical guide 133.Wherein, the connector 132 is driven by the power transmission member 131 and is moved up and down, the connection
Part 132 is fixedly connected on the side of the upper housing 11 with bolt 16 again simultaneously, can effectively reduce the place headroom that installation needs
Highly, it is more convenient installation and maintenance.
As shown in Figure 1 and Figure 7, the transmission mechanism may be provided at the bottom position of lower case 12 comprising: motor 134,
Twin shaft output worm-gear speed reducer 135, two for being connected to 135 left and right sides of twin shaft output worm-gear speed reducer
Transmission shaft 136, the accurate angular deformation speed machine being connect positioned at the left and right sides with the transmission shaft 136 and power transmission member 131
137.The power of the motor 134 passes to the twin shaft output worm-gear speed reducer 135, using the transmission of two sides
Axis 136 is transferred to the accurate angular deformation speed machine 137, which transfers power to the power again and pass
Component 131 is passed, the connector 132 is thus driven to move up or down, and then drives upper housing 11 corresponding upward or downward
It is mobile.Wherein, as needed, the accurate angular deformation speed machine 137 can both use booster engine, can also use speed reducer, this
In embodiment, using booster engine, noise is advantageously reduced.
In the present embodiment, the power transmission member 131 is two for being separately positioned on 11 left and right sides of upper housing
Lead screw, accordingly the upper housing 11 is each side fixed with the connector 132 driven by the lead screw 131.
The present invention drives bilateral lead screw 131 to rise or fall with follower link 132 and upper housing 11 simultaneously using a motor, it is ensured that
The synchronization of two sides lifting, is not in the phenomenon that blocking.And screw structure cooperates turbine worm reducer, has using worm and gear
There is a self-locking function, when unlatching, falling accident never occurs for upper housing shielding case, has greatly ensured the safety of operator.
It can guarantee that gate remains tight closure when simultaneously closing off, advantageously ensure that test equipment reaches shielding properties index.
The present invention cooperates above-mentioned accurate angular deformation speed machine 137 to have following three reasons using worm-gear speed reducer 135:
The first, system support direct current generator, and conventional DC brushless motor speed is high, generally all in 3000RPM, uses Hardened gear face
Noise can very greatly (60dB) under high speed input condition for deceleration mechanism.The input of motor can be turned down by worm-gear speed reducer
Revolving speed, then the final revolving speed that revolving speed reaches needs is amplified by accurate angular deformation speed machine, it can be noise control in acceptable
Range.
The second, so that turbine and worm is had more superior self-locking property by the worm and gear reduction ratio of increase, prevent screw rod
It takes a turn for the worse in the case where load.
Third utilizes the self-locking property of Article 2, can remove the brake of motor, real using the input shaft of worm and gear
Function that is existing manually opened and closing.
As shown in fig. 6, the connector 132 include: drive block 1321, horizontal cross plate 1322, vertical traversing plates 1323 and
Slide construction 1324.The drive block 1321 is equipped with and internal screw thread and is threadedly coupled with the lead screw 131, when 131 forward direction of lead screw or
When rotating backward, the drive block 1321 can be driven to move up or move down.The drive block 1321 is bolted to connection in level
The middle part of transverse slat 1322, the vertical traversing plates 1323 are then fixed on the inside of (such as welding) horizontal cross plate 1322.Such as Fig. 5 institute
Show, 11 side wall of upper housing and the 1323 position corresponding position of vertical traversing plates are fixed with connecting plate 15, the vertical traversing plates 1323
It links together with the bolt 16 of connecting plate 15.The slide construction 1324 is fixedly arranged on horizontal cross plate 1322 and vertical traversing plates respectively
1323 rear and front ends, as shown in figure 4, the slide construction 1324 is slidably connected with the vertical guide 133 cooperation, so that connector
132 can only move up and down along the vertical guide 133, which can be used common guiding form, such as: round straight line
Sliding rail, line slide rail, idler wheel raceway device etc., and the quantity of guide rail is unlimited.Above-mentioned horizontal cross plate 1322 and vertical traversing plates 1323
Setting can reinforce the integral strength of connector 132.
As shown in figure 4, the left and right sides of the shield shell 1 is respectively provided with the support frame for being fixed on the lower case 12
Frame 5, the braced frame 5 are mainly horizontal by two or more of the vertical connector 51 in front and back two and this two vertical connectors 51 of connection
It is constituted to connector 52.The lead screw 131 and connector 132 are located in the braced frame 5, the front of every side braced frame 5 and
The vertical guide 133, the slide construction with 132 rear and front end of connector are respectively installed at the vertical connector 51 in rear portion
1324 are slidably matched.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
