Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 to Fig. 4 be it is described in the utility model exempt from lock expansion tightening wheel mechanism, the mechanism include expansion tightening wheel 5, tension shaft 4,
Adjust bolt 6 and connecting plate 1.Tension shaft 4 includes tensioner shaft body 401, connection bump 402 and link slot 403, connection bump
402 side is fixedly connected with tensioner shaft body 401, and the other side is equipped with link slot 403.Tensioner shaft body 401 is arranged in tensioner
In wheel 5, being set between the inner wall and tensioner shaft body 401 of expansion tightening wheel 5 there are two bearing 2, bearing 2 is fixedly connected with expansion tightening wheel 5, this
Expansion tightening wheel and bearing are by injection molding hot pressing combination connection in embodiment, and by the way that bearing 2 is arranged, tension shaft 4 can be in expansion tightening wheel 5
Rotation.One end of tensioner shaft body 401 is fixedly connected with connection bump 402, the other end of tensioner shaft body 401 and bearing 2 it
Between be equipped with outer circlip 3, by the way that outer circlip is arranged, expansion tightening wheel 5 and bearing 2 are stuck in connection bump 402.
It is equipped with internal thread hole in connection bump 402, adjusts bolt 6 and is arranged in the internal thread hole of connection bump 402, adjust
The external screw thread of bolt is meshed with the internal screw thread of internal thread hole, and the screw thread for realizing connection bump 402 and adjusting between bolt 6 connects
It connects.It adjusts in 6 rotation process of bolt, link protrusion 402, tension shaft 4 and expansion tightening wheel 5 can be driven to move up and down.
The top of connecting plate 1 is fixed with screw bolt installing frame 7, adjusts bolt 6 and is arranged in the mounting hole of screw bolt installing frame 7,
Realize the positioning for adjusting bolt 6.The middle part of connecting plate 1 is equipped with expansion tightening wheel mounting groove 101 and expansion tightening wheel mounting hole 102, tensioner
Wheel mounting hole 102 is located at the lower section of expansion tightening wheel mounting groove 101, and is interconnected.Expansion tightening wheel mounting groove 101 is along the vertical direction
Strip slot, when which works, the tension shaft at link slot 403 is arranged in expansion tightening wheel mounting groove 101, link slot 403
