For achieving the above object, the present invention is by the following technical solutions:
The flexible tension structure of a kind of chain of the present invention, comprise chain, sprocket wheel and chain pulley seat, described chain pulley seat one side forms supporting axle, described sprocket wheel is located on supporting axle by bearing is rotatable, described chain pulley seat slidably is located on guide rail, described guide rail is fixed on positive stop, and described chain pulley seat one end is connected with the tensioning damping mechanism.
Wherein, described tensioning damping mechanism comprises backstop, the guide pillar that is fixedly connected with chain pulley seat one end, described guide pillar is horizontally placed on the glide direction of chain pulley seat, described backstop is provided with the through hole that can supply guide pillar to pass, be equipped with spring on described guide pillar, described both ends of the spring is inconsistent with chain pulley seat and backstop respectively.
Further, described guide rail has two, and the parallel two ends up and down of being located at positive stop one side, described chain pulley seat both sides correspondence respectively are located on the guide rail of two of up and down.
Further, described spring overcoat is provided with sleeve.
Further, described positive stop is provided with the stroke control mechanism of chain pulley seat.
Further, described stroke control mechanism comprises the adjusting bolt that is arranged on positive stop, the setting of the inner sensing of described adjusting bolt chain pulley seat.
Beneficial effect of the present invention is: in terms of existing technologies, the present invention includes chain, sprocket wheel and chain pulley seat, described chain pulley seat slidably is located on guide rail, described guide rail is fixed on positive stop, and described chain pulley seat one end is connected with the tensioning damping mechanism, and chain of the present invention and sprocket wheel are when coordinating transmission, by the tensioning damping mechanism, timely adjustment is carried out in the position of sprocket wheel and chain pulley seat, thereby reach the technical purpose of loading between chain and sprocket wheel, avoid chain to jump tooth, even transmission failure.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, the flexible tension structure of a kind of chain of the present invention comprises chain 1, sprocket wheel 2 and chain pulley seat 12, and described sprocket wheel 2 is by sprocket 13 and chain 1 fit engagement transmission.Described chain pulley seat 12 1 sides form supporting axle 4, and described sprocket wheel 2 is located on supporting axle 4 by bearing 3 is rotatable.Described chain pulley seat 12 slidably is located on guide rail 5, and described guide rail 5 is fixed on positive stop 11, and described chain pulley seat 12 1 ends are connected with the tensioning damping mechanism.Said structure consists of agent structure of the present invention.
Wherein, described tensioning damping mechanism comprises backstop 9, the guide pillar 8 that is fixedly connected with chain pulley seat 12 1 ends, described guide pillar 8 is horizontally placed on the glide direction of chain pulley seat 12, described backstop 9 is provided with the through hole (not shown) that can supply guide pillar 8 to pass, be that described guide pillar 8 can move left and right with chain pulley seat 12, the through hole on described backstop 9 is the moving walkway of guide pillar 8.Be equipped with spring 7 on described guide pillar 8, described spring 7 two ends are inconsistent with chain pulley seat 12 and backstop 9 respectively, and described spring 7 mainly plays the mobile reset response of chain pulley seat 12.When chain 1 coordinates sprocket wheel 2 to begin to start, when starting beginning, the active force of the active force that chain 1 is subject to when working at ordinary times, this moment, chain pulley seat 12 moved to right, spring 7 compressions, alleviate the suffered active force of chain 1, after working well, spring 7 recovers normal, and the normal engagement running of chain 1 and sprocket wheel 2 that is to say that the present invention carries out timely adjustment by the tensioning damping mechanism to the position of sprocket wheel and chain pulley seat, thereby reach the technical purpose of loading between chain and sprocket wheel, avoid chain to jump tooth, even transmission failure, greatly improved stability of the present invention.
The preferred described guide rail 5 of the present invention has two, and the parallel two ends up and down of being located at positive stop 11 1 sides, described chain pulley seat 12 both sides correspondence respectively are located on the guide rail 5 of two of up and down, and setting, be conducive to chain pulley seat 12 smooth sliding like this, further improves stability of the present invention.
