As shown in Figure 2 and Figure 4, the support 22 is metal structure, including the He of bracket main body portion 221
Sliding support portion 222, the bracket main body portion 221 is substantially cylindrical, in the bracket main body portion
Through hole 2211 and accommodating hole 2212 are formed with, accommodating hole 2212 is arranged on the surface of the through hole,
Can be can also communicating of separating, accommodating hole 2212 is used for the screw rod for accommodating the scale 21
Portion and scale portion are passed through, accommodating hole 2212 of the bracket main body portion towards the motor side
Position forms a recess, the step 214 between the recess and the scale portion and handle portion of the scale
Engaging so that handle portion is placed in the outside of the support.
The sliding support portion 222 is two symmetrical segmental arcs, by the bracket main body portion 221 1
The end 223 of the support is directly extended to, its end 223 forms locating slot 2231 and positioning hole 2232,
The locating slot 2231 is used for the end for accommodating the threaded shank 213 of the scale 21.
The transmission mechanism 2 also includes drive screw 23, and the drive screw surface forms helicitic texture,
The drive screw is through the through hole 2211 in the bracket main body portion, and its one end is arranged on rack body
On the outside of portion, drive connection portion is formed, its other end extends to the end of sliding support portion 222 of the support
In the positioning hole 2232 that portion is formed, the first stopper section and second are additionally provided with the drive screw 23
Stopper section, forms a certain distance between the first stopper section and the second stopper section, drive screw 23 can be with
Freely rotated in institute's support.
As shown in fig. 6, the transmission mechanism 2 also includes linkage block 24, the linkage block 24 includes
First connecting portion 241, interstitial hole 242 and second connecting portion 243, the first connecting portion 241 is with
Between the cylindrical structure set up and down of hole 242, the second connecting portion 243 be arranged on it is described first connect
The both sides of socket part 241, optionally, only can also be set in side, the first connecting portion 241
Surface is formed with screw thread, and the first connecting portion 241 is set in the outside of the drive screw 23, and
Screw thread engagement is formed, at any driving condition, the first connecting portion 241 drives described drive screw 23
Linkage block 24 is moved forward or rearward, the interstitial hole 242 be set in the scale 21 (or elasticity
Element 3) outside, and form mobile space in the circumferential, the second connecting portion 243 with it is described
Push rod is fixedly connected, so, under the instrumentality of linkage block 24, and motor can be with driving push rod
It is mobile.
As shown in Figure 7 and Figure 8, the transmission mechanism 2 also includes sliding shoe 25, the sliding shoe 25
Including body 251 and two symmetrical travelling arms 252, through hole 253 is formed on the body 251,
The threaded shank of the scale passes through the sliding shoe, two travelling arms 252 by the through hole 253
Support is in the sliding support portion 222 of support, it is possible to slided along the sliding support portion.As schemed
Show, the body 251 of the sliding shoe 25 includes first end face 254 and second end face 255, described the
The recess 256 of an indent is formed on biend 255, the recess 256 is arranged on institute for receiving
State the stop nut 4 on scale.Spring one end outside scale is resisted against the bracket main body portion 221,
Its other end against the sliding shoe first end face 254, in the effect of the stop nut and spring
Under, the sliding shoe can be fixed on some position on scale, need to overcome when stretching out scale
The elastic force of spring, the sliding shoe being now fixed on scale can be moved towards linkage block together with scale,
Until sliding shoe 25 stops against linkage block 24, it is impossible to pull on, read data, when loosing one's grip
The lower scale of elastic force effect is retracted into origin-location.
When drive device (such as motor) drives the drive screw turns, linkage block movement is driven
When, scale is not moved yet, in relative static conditions, is still in the antenna house body, it is necessary to say
It is bright, with being moved forward or rearward for linkage block, and because sliding shoe is also static, so
The stretched scale registration of scale is also change, such as, and linkage block is moved to the threaded shank of scale,
It is stretchable apart from shorter and shorter, the readable registration of scale is also less and less, conversely, the readable of scale
According to also increasing, with antenna actual demand, the position of stop nut 4 can be adjusted, is realized not
With the use of wave band antenna.
Above-described embodiment is the preferred embodiments of the present invention, optionally, is also applied in the present invention
The antenna for base station adjusted manually, i.e., described drive device is hand adjustment drive mechanism.
In addition, alternatively, drive device and electronic control unit can be with whole in the present invention
Body or be dispersedly arranged within the cover body, realize scale and electricity adjust control unit be all arranged in
Within cover body.
The present invention is ingenious in design, by the way that scale is arranged on inside cover body, it can be ensured that scale label is exempted from
Affected by environment and fuzzy or damage, effectively the service life of extension product when checking, it is necessary to only need
Scale is pulled out, scale has been checked automatically in retraction antenna house body, easy to operate, the handle of scale
Portion is resisted against on support by elastic force, plays preferable sealing effectiveness, simultaneously as scale be interior
Install the installation or maintenance for also not interfering with other parts outside cover body.
The technology contents and technical characteristic of the present invention have revealed that as above, but are familiar with those skilled in the art
Member is still potentially based on teachings of the present invention and announcement and makees a variety of replacements without departing substantially from spirit of the present invention and repair
Decorations, therefore, the scope of the present invention should be not limited to the content disclosed in embodiment, and should include various
Without departing substantially from the replacement and modification of the present invention, and covered by present patent application claim.
