Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, be a kind of tension stability component in the utility model preferred embodiment, including steady wheel 1 and chain
Part 2, chain condition 2 include the winding chain 21 being arranged on steady wheel 1 and the threaded rod 22 being fixedly connected with the one end of chain 21, spiral shell
The first nut 23 and the second nut 24 are provided with rasp bar 22, the second nut 24 is located at the one end of threaded rod 22 away from chain 21,
Finite place piece 25 is arranged on threaded rod 22 between first nut 23 and the second nut 24, between the nut 24 of locating part 25 and second
Threaded rod 22 on be arranged with elastic component 26, elastic component 26 is spring.In use, steady wheel 1 is fixed on to the unwrapping wire of steel cord
On wheel, after chain 21 is partially around on steady wheel 1, locating part 25 and chain 21 are not connected with to the other end of threaded rod 22
It is separately fixed on the pay off rack of steel cord, by adjusting the distance between the first nut 23 and the second nut 24 and locating part,
The adjustment of tension force can be achieved, presence and chain 21 fastness of itself due to flexible part 26, it is ensured that tension force it is long-term
Stable output.
In embodiment, as shown in Figure 2-5, steady wheel 1 includes wheel body 11 and the shield being circumferentially provided on wheel body 11
Ring 12, retaining ring 2 are in substantially I-shaped, and friction member 13 is provided with retaining ring 2, and the thickness of friction member 13 is not more than the depth of retaining ring 2,
It is difficult for drop-off and more secure when used after wheel body 11 can so to ensure that chain 21 is around in.
Further, the inwall of retaining ring 12 is concavely provided with neck 121, is convexly equipped with what is matched with neck 121 on friction member 13
Projection 131, is easy to the assembling of friction member 13；And through hole 122 is additionally provided with the side wall of retaining ring 12, it is provided with and leads on friction member 12
The screwed hole 132 of the position correspondence of hole 122, fixation of the friction member 13 in retaining ring 12 can be achieved by bolt.
In order to increase smooth degree so that tension force output is more stable, and it is parallel with being fixed on that friction member 13 includes parallel portion 13a
