Detailed description of the invention
For comparing intuitively, being fully understood by the technical solution of the utility model, now just combine this utility model accompanying drawing and carry out
Nonrestrictive feature description is as follows:
As shown in Figure 1-Figure 3, folding yagi aerial, including mobile jib 1, mobile jib 1 is sequentially provided with first from top to bottom and guides bar into
Mechanism 2, second guide linkage 3 and the 3rd into and guide linkage 4 into；First guides linkage 2 into includes being symmetricly set on mobile jib 1 both sides
First guide bar assembly 21 into, first guides bar assembly 21 into includes that be fixed on mobile jib 1 first fixes seat 211 and rotatable
Be arranged on first fix on seat 211 first guide bar body 212 into；Second guides linkage 3 into includes being symmetricly set on mobile jib 1
The second of both sides guides bar assembly 31 into, and second guides bar assembly 31 into includes that be fixed on mobile jib 1 second fixes seat 311 and can
Be rotatably mounted at second fix on seat 311 second guide bar body 312 into；3rd guides linkage 4 into includes being symmetricly set on
Mobile jib 1 both sides the 3rd guide bar assembly 41 into, the 3rd guide into bar assembly 41 include the be fixed on mobile jib 1 the 3rd fix seat 411 with
And be installed in rotation on the 3rd fix on seat 411 the 3rd guide bar body 412 into；Second to guide the length of bar body 312 into big
In the first length guiding bar body 212 into and the length of guiding bar body 412 into less than the 3rd, wherein one second guide bar assembly 31 into
On a balun 5 is installed.
First the inner guiding bar body 212 into is joined with the first outer end rotation fixing seat 211 by one first jointed shaft 6
Close；Second the inner guiding bar body 312 into is rotatably assorted with the second outer end fixing seat 311 by one second jointed shaft 7；3rd
The inner guiding bar body 412 into is rotatably assorted with the 3rd outer end fixing seat 411 by one the 3rd jointed shaft 8.Hands during use
Break and first guide bar body 212 into, second guide bar body 312 and the 3rd into and guide bar body 412 into and i.e. they can be folded up.
Installing balun 5 for convenience, wherein one second guide into and have a fixed block 9 on bar body 312, balun 5 is arranged on
On fixed block 9.The volume of balun 5 is little, when folding yagi aerial and being in folded state, will not take bigger space, convenient
Storage and carrying.
3rd guide into the spacing that bar body 412 and second guides between bar body 312 guide into more than first bar body 212 with
Second guides the spacing between bar body 312 into.Because the second length guiding bar body 312 into guides bar body 212 into more than first
Length and the length of guiding bar body 412 into less than the 3rd, so by guide into first bar body 212, second guide into bar this
Body 312 and the 3rd is guided the spacing between bar body 412 into and is arranged, and facilitates first to guide bar body 212 into, second guides bar body into
312 and the 3rd foldings guiding bar body 412 into.
Folding yagi aerial provided by the utility model, mobile jib 1 be sequentially provided with from top to bottom first guide into linkage 2,
Second guides linkage 3 and the 3rd into guides linkage 4 into, if during use rotate first guide into bar body 212, second guide into bar this
Body 312 and the 3rd is guided bar body 412 into and just can be guided bar body 212 by first into, second guide bar body 312 and the 3rd into and guide into
Bar body 412 is folded up, and needs to guide into first when using bar body 212 again, second guides bar body 312 and the 3rd into and guide into
Bar body 412 launches.
Certainly, these are only preferred embodiment of the present utility model, non-the most i.e. limit to patent of the present utility model
Scope, all utilization this utility model description and graphic content institute are simple for it modifies and equivalent structure change, all should in like manner wrap
