Embodiment two
The present embodiment is similar with embodiment one, and its difference is, in the present embodiment, it is provided that the present invention's is another kind of real
Execute the angle display 10 of mode.
Seeing Figure 12 to Figure 14, described angle display 10 is mainly by housing (non-label, lower same), angle scale 1020, line
Wheel 1040, reset element 1060 are constituted.
Described housing is made up of upper casing 1010 and lower casing 1030.Described upper casing 1010 and/or lower casing 1030 have form (not
Label) and the reading pointer 1011 of close form setting, for the current tilt angled down of marker antenna, described upper casing 1010 and lower casing
1030 are made of clear material, and for through the angular values on housing viewing angle scale 1020, described lower casing 1030 is at its axle
To side form sleeve 1031, and this sleeve 1031 sidewall is provided with opening 1032 so that one end of pull rope 1050 from
This opening 1032 passes.
Being carved with scale 1021 at least one end face of described angle scale 1020, described angle scale 1020 outer peripheral edge forms the
One external tooth 1022.Described angle scale 1020 top middle portion position is provided with mandrel (non-label), and described central shaft is installed on
In the centre bore of housing, so that described angle scale 1020 can be relative to housing into rotation.
The outer peripheral edge of described line wheel 1040 forms the second external tooth matched with the first external tooth 1022 of angle scale 1020, institute
State line wheel 1040 to be placed in described sleeve 1031, and described line wheel 1040 is by its second external tooth 1042 and angle scale 1020
First external tooth is meshed, and then realizes the transmission of line wheel 1040 and angle scale 1020.
It can be seen that described housing can be regarded as by for installing the angle tray salver of angle scale 1020 and axial in angle tray salver
Side forms and is used for installing the sleeve 1031 of described line wheel 1040 and constitutes.
Described pull rope 1050 is wound around online wheel upper (in the wire casing offered on such as line wheel) through described opening 1032, its
When being displaced outwardly under transmission nut effect, band moving-wire wheel 1040 and angle scale 1020 rotated, when certain a moment on angle scale 1020
When degree 1021 turns to reading pointer 1011 position on housing, this scale 1021 is the current tilt angled down of antenna.
Further, described angle display 10 can realize the calibration function of the initial scale of angle scale 1020.
In the present embodiment, described line wheel 1040 is main by the sheave 1041 in I shape, gear 1042, Flexible Connector
1043 (such as compression spring) forms.Described sheave 1041 top is provided with centre bore (non-label, lower same), described gear 1042

Stating the corresponding position of key tooth and offer keyway 10411, described sheave 1041 and gear 1042 are by keyway 10411 and key tooth
The connection that cooperates of 10421, and gear 1042 can slide axially along sheave 1041, thus realize the movement of gear 1042
Guide effect.
Described gear 1042 other end is provided with connection post 10422, and by connecting post 10422 with described upper casing 1010 even
Connect, and described connection post 10422 can extend to hull outside with through described upper casing 1010.
The central shaft top of described angle scale 1020 also has polygonal adjusting hole 1023, the corresponding institute of described upper casing 1010
State adjusting hole 1023 and offer adjustment window 1012, to utilize the adjustment part (not shown) in mating connection with this adjusting hole 1023 to wear
Cross adjustment window 1012 and insert the initial position twisting described angle scale 1020 in adjusting hole 1023 to calibrate described angle scale 1020.
Concrete calibrating principle is as follows:
When pressing down on the connection post 10422 of gear 1042, Flexible Connector 1043 compresses, and makes gear 1042 and angle
Dish 1020 departs from, and the adjusting hole 1023 now by adjustment part fit angle dish 1020 central shaft top carrys out angle of rotation scale
1020, and then adjust the initial angle position of angle scale 12 at housing reading pointer 1011, carry out tilt angled down initial value
Calibration, unclamps described connection post 10422, makes gear 1042 recover under the elastic force effect of Flexible Connector 1043 after having calibrated
To in situ (i.e. its second external tooth engages again with the first external tooth 1022 of described angle scale 1020).
Described reset element 1060 is torsion spring, and described housing also includes the sleeve lower cover being connected with described sleeve 1031
1070, the bottom of described sheave 1041 is provided with lower centre bore (not shown), and described sheave 1041 is stretched in one end of described torsion spring
In lower centre bore so that one end is resisted against on described sheave 1041, and the other end is pushed against on sleeve lower cover 1070.
When under the drive of transmission nut 222, pulls wire wheel 1040 (specially sheave 1041) rotates pull rope 1050,
Torsion is accumulated by rotary compression as the torsion spring of reset element 1060；When transmission nut 222 reversely moves, pull rope 1050
Disappearing the pulling force of line wheel 1040, line wheel 1040 rotates backward under the twisting force of torsion spring, makes pull rope 1050 be wound around online
On wheel 1040.Described lower cover 1070 snaps onto on the sleeve 1031 of lower casing 1030.
