Specific embodiment
A kind of chain drive expansion mechanism, including main frame beam 1, head sprocket 2, bolt 3, adjusting bolt A4, link block A5, company
It meets block B6, pin shaft 7, motor fixed plate 8, coulisse 9, adjust bolt B 10, link block C11, chain 12, accessary sprocket wheel 13, bush seat
Bracket 14, bush seat 15, drive shaft 16, bolt 17, motor 18, gusset 19, bottom plate 20 have on the motor fixed plate 8 several
Long hole 81, the bolt 3 pass through long hole 81 to coulisse 9, and the motor fixed plate 8 is fitted in one by bolt 3 and coulisse 9
It rises, the side of the coulisse 9 has link block C11, link block C11 to connect with bolt B 10, adjusts bolt B 10 in turning effort
Under, the movement of motor fixed plate 8 is pushed or pull on forward, relatively moves motor fixed plate 8 with coulisse 9, the coulisse 9
The other side have and adjust bolt A4, link block A5, link block B6 and pin shaft 7, the link block A5 and coulisse 9 are connected to one
It rising, the adjusting bolt A4 is linked together by link block A5 and link block B6, pin shaft 7 is installed adjusting the front end bolt A4,
The link block B6 links together with motor fixed plate 8, is pushed under the turning effort for adjusting bolt A4 by link block B6
Or pulling motor fixed plate 8 mobile, the motor fixed plate 8 is linked together by bolt 17 with motor 18, and head sprocket 2 is installed
On the output shaft of motor 18, the coulisse 9, gusset 19 and bottom plate 20 link together, and the motor 18 is fixed with motor
After plate 8 connects, motor 18 moves in 9 through-hole 91 of coulisse under the drive of motor fixed plate 8, the head sprocket 2 with from chain
In the same plane, the drive shaft 16 links wheel 13 with bush seat 15, and bush seat 15 is connect with bearing shell seat support 14, bush seat
Bracket 14 is connect with main frame beam 1, and the accessary sprocket wheel 13 is threadedly connected to drive shaft 16.
As shown in Figures 1 to 5, chain 12 can lead to the problem of loosening, 2 adjustings shown in fig. 5 in use for some time
Bolt B 10 will push or pull motor fixed plate 8 to generate the displacement relative to coulisse 9 when inwardly rotating, be fixed in motor
Motor 18 in fixed plate 8, the head sprocket 2 for being fixed in motor 18, the chain 12 on head sprocket 2 can to same direction of displacement into
Row movement, thus swelling chain 12；When 2 adjusting bolt A4 are inwardly rotated, it will push or pull motor fixed plate 8 to generate phase
Displacement for coulisse 9, the motor 18 being fixed on motor fixed plate 8, the head sprocket 2 for being fixed in motor 18, on head sprocket 2
Chain 12 can be moved to same direction of displacement.Wherein, the through-hole 91 of coulisse 9 limits the movement of motor 18, makes it
It can only be moved at the direction perpendicular to 91 axis of through-hole, while ensure that mobile, front and back portion of chain still keeps same flat
On face.
Finally it should be noted that the above content is only to illustrate the technical solution of the utility model, rather than it is practical to this
The limitation of novel protected range, those skilled in the art to the technical solution of the utility model carry out it is simple modification or
