One end of wheel 220 is equipped with the button 221 to fasten with card body 114 and compresses body 223, button through what installation through-hole 112 was set
221 are arranged at the outside for compressing body 223；And swinging mounting 300, swinging mounting 300 can be rotated relative to mounting bracket 100, rotate
Stent 300 is equipped with least two arc boss with compressing pressure-bearing surface 310 that body 223 is pressed against each other and being arranged at pressure-bearing surface 310
320, all arc boss 320 are provided at circumferentially spaced along same, arc boss 320 include guide end 322, anti-reverse end 324 and
The ligand 326 being arranged between guide end 322 and anti-reverse end 324, only when ligand 326 and compresses body 223 and offsets, makes button
When body 221 is separated with card body 114, output gear 220 just can drive output shaft 210 to rotate；When compressing for output gear 220
When body 223 compresses cooperation with any ligand 326, remaining output gear 220 is locked out and at least one output gear 220
324 anti-reverse of anti-reverse end for compressing body 223 and one of arc boss 320 coordinate.
As shown in Figures 1 to 10, by above-mentioned linkage locking mechanism 10 be applied to Downtilt control device in, using turn
The arc boss 320 of dynamic stent 300 and the spline structure for compressing the composition of body 223, while utilize planetary wheeling mechanism and unidirectionally controlled
Mechanism, makes swinging mounting 300 for planet carrier and only rotates in one direction, while utilizes arc boss 320 and output gear
220 body 223 that compresses coordinates the engaging and separation for realizing card body 114 and button 221, enables 220 self-locking of output gear or solution
Lock；
Specifically, when needing to drive some output gear 220 to rotate, control swinging mounting 300 turns to corresponding position
Put, make to compress body 223 and compress cooperation with ligand 326, when the button 221 is separated with card body 114, it is corresponding defeated to complete the antenna
Go out the unlock of gear 220, at this time output gear 220 can be driven to rotate, and then drive the rotation of output shaft 210, utilize output shaft
210 complete power output, complete the angle of declination angle adjustment of the antenna；During this, remaining output gear 220 be locked out and
The anti-reverse end 324 anti-reverse cooperation for compressing body 223 and one of arc boss 320 of at least one output gear 220,
And then during driving, other output gears 220 are not interfered with, realize man-to-man driving, while make output gear yet
220 is more accurate with engaging for input gear (such as the first driven gear 24, the second driven gear 34).The linkage locking mechanism 10
Stop structure altogether using integrated, the positioning datum using output gear 220 and anti-reverse end 324 for stop, lifting gear engagement essence
Degree, can lift the control accuracy of the tilt angled down adjustment of two or more beam antennas.
It should be further noted that the quantity and adjacent spacing of arc boss 320 can be according to the numbers of output gear 220

When anti-reverse end 324 anti-reverse of arc boss 320 coordinates, in remaining output gear 220, only output gear 220 supports
The ligand 326 of laminate 223 and an arc boss 320 compresses cooperation " any combination, belong to required by the utility model
The scope of protection.
Specifically, as shown in Fig. 5, Fig. 7 and Fig. 8, implemented with eight output gears 220 and two arc boss 320 for one
Example, " 0 " represent to release locking (+)；" 1 " represents to release locking (-)；" 2 " represent locking；" 3 " represent to prevent from reversing, gear-like
State sees below table 1.Conclusion：There is an only gear for relieving locking in each state, remaining 220 quilt of output gear
Locking, and minimum of one output gear 220 is prevented from reversing.
As shown in Fig. 6, Fig. 9 and Figure 10, with eight output gears 220 and eight arc boss 320 for an embodiment, " 0 "
Represent to release locking and direction of rotation (+) counterclockwise；" 1 " represents to release locking and clockwise direction of rotation (-)；“2”
Represent locking；" 3 " represent to prevent from reversing, and gear condition sees below table 2.Conclusion：There is only one solution in each state
Except the gear of locking, remaining output gear 220 is locked out and is prevented to reverse.
Further, during the first predeterminated position that swinging mounting 300 is in, the button 221 of all output gears 220 is distinguished
Fasten with corresponding card body 114, all output gears 220 are locked out, and at least one output gear 220 compresses body
223 are compressed by anti-reverse.And then can be by adding anti-reversing structure, during the first predeterminated position for being in swinging mounting 300, institute
The button 221 for having output gear 220 fastens with corresponding card body 114 respectively, and all output gears 220 are locked out and turn
Dynamic stent 300 can not take a turn for the worse dynamic；Because the flexible reset function of output gear 220, makes swinging mounting 300 light
Easily rotate forward；Thus output gear 220 is locked during usually use, avoid Downtilt normal use
When, because collision or other factors change；Only when needing adjustment and the corresponding output gear of antenna that is adjusted
220 could unlock, further improve 220 and first driven gear 24 of output gear or the second driven gear 34 the accuracy of mesh and
The control accuracy of output gear 220.
1 eight output gears 220 of table and two 320 analysis of movement tables of arc boss

Sense of rotation between first driven gear 24 and the second driven gear 34 is opposite；When the drive first of the first driving gear 23 is driven
When gear 24 is rotated along the opposite direction of the first direction of rotation, because ring gear 22 cannot be rotated along the opposite direction of the first direction of rotation,
Ring gear 22 is fixed, and the first driven gear 24 is revolved round the sun, while drives swinging mounting 300 to be carried out along the first direction of rotation
Rotate；Swinging mounting 300 is turned to in requisition for the position of adjusting, make output gear 220 compresses body 223 and ligand 326
Cooperation is compressed, when the button 221 is separated with card body 114, the corresponding output gear 220 of the antenna is completed and completes unlock, make at the same time
First driven gear 24 or the second driven gear 34 are meshed with the output gear 220；The direction of rotation in reverse drive source, first
Driving gear 23 drive the first driven gear 24 along the first direction of rotation carry out rotation, the second driving gear 32 drive second from
Moving gear 34 carries out rotation along the opposite direction of the first direction of rotation, and the first ring gear 22 can be rotated along the first direction of rotation at this time,
Because the first driven gear 24 or the second driven gear 34 are engaged with 220 axis of output gear, and then 220 turns of output gear can be driven
It is dynamic, and then drive the rotation of output shaft 210 and complete power output using output shaft 210, complete the angle of declination angle of the antenna
Adjustment；During this, remaining output gear 220 be locked out and at least one output gear 220 compress body 223 with wherein
324 anti-reverse of anti-reverse end of one arc boss 320 coordinates, and fixes swinging mounting 300, and then during driving, no
The angle of declination change of other antennas can be influenced, realizes man-to-man driving, while also make 220 and first driven gear of output gear
24 or second driven gear 34 engagement it is more accurate.When adjusting next time, then allow the first driven gear 24 and the second driven tooth
34 rotations and revolution are taken turns, after arrival needs adjusting position, then makes the 34 progress rotations of the first driven gear 24 and the second driven gear,
