Referring to Fig.1-2, a kind of Antiskid belt pulley, including wheel body 5, it is rigid integrally formed with multiple supports on the inner ring of wheel body 5
Body 2 supports the one end of rigid body 2 far from wheel body 5 integrally formed with axle sleeve 3, and the two sides of wheel body 5 are rotatably connected to anti-pulley 4, and two
One end that a anti-pulley 4 is located remotely from each other is rotatably connected to protective plate 1, is equipped with pre-tightening mechanism in anti-pulley 4, anti-pulley 4 with
There are gaps between protective plate 1, while anti-pulley 4 and wheel body 5, there are gap, anti-pulley 4 turns between wheel body 5 and protective plate 1
Dynamic, pre-tightening mechanism is used to increase the pressure between belt and wheel body 5.
It illustrates, referring to Fig. 3, pre-tightening mechanism includes connecting rod 9, the first spring 10, inner ring body 7, support shaft 6 and internal axle sleeve
8, anti-pulley 4 is four arc-shaped slide plate compositions, is welded with symmetrical two connecting rods 9 on the inner wall of each anti-pulley 4, each
Connecting rod 9 slidably connects inner ring body 7 jointly, and multiple support shafts 6 are welded on the inner wall of inner ring body 7, are total in each support shaft 6
With internal axle sleeve 8 is welded with, connecting rod 9 is socketed with the first spring 10, the first bullet on the body of rod between anti-pulley 4 and inner ring body 7
The upper and lower ends of spring 10 are welded on anti-pulley 4 and the one end close to each other of inner ring body 7, pass through the elastic reaction of the first spring 10
Power can push anti-pulley 4, and anti-pulley 4 drives connecting rod 9 to move on inner ring body 7, to make anti-pulley 4 push belt, to increase
The pressure of big belt and wheel body 5 plays anti-skidding effect to increase the frictional force between belt and wheel body 5, and pre-tightening mechanism rises
The effect for increasing pressure between belt and wheel body 5 is arrived.
More specifically, connecting rod 9 through inner ring body 7 and is welded with block 13, block close to one end of inner ring body 7 referring to Fig. 3
13 width is greater than the width of connecting rod 9, connecting rod 9 can be prevented to be detached from inner ring body 7 by block 13.The position of 7 respective link 9 of inner ring body
It sets and is welded with multiple fixed sleevings 12, slidably connect pushing block 11 in fixed sleeving 12, it, can by fixed sleeving 12 and pushing block 11
The rigidity of support for improving connecting rod 9 makes connecting rod 9 drive anti-pulley 4 more stable.
Further illustrate, referring to Fig. 4-5, the inner ring diameter of internal axle sleeve 8 is identical with the inner ring diameter of axle sleeve 3, internal axle sleeve 8 and
