The technical scheme is that a kind of Novel chain structure, including multiple link units, the link units include The axle sleeve of two blocks of carrier bars, No. I chain pin being fixed on carrier bar, No. II chain pin and sleeve on No. I chain pin, No. II chain pin, the chain The rotating bar of rotation is provided on the outside of plate, the free end of the rotating bar is provided with guide wheel, is provided with adjusting on the outside of the carrier bar The adjusting component of rotating bar rotational angle.
It is provided with fixing axle on the outside of the carrier bar, forms through-hole in the rotating bar, the fixing axle is inserted into through-hole.
The free end of the fixing axle is provided with the nut for avoiding rotating bar from skidding off.
The turning end of the rotating bar is provided with bracket, and the guide wheel setting is in the bracket.
The bracket is vertical with rotating bar.
The component that adjusts includes the lateral guide groove at carrier bar outer wall, and the sliding block of sliding is provided in the lateral guide groove, The sliding block outer wall is hinged with connecting rod, and the connecting rod other end and rotating bar are hinged.
The guide wheel leans out carrier bar lower end.
The jackscrew of fixed sliding block is provided at the sliding block outer wall.
The present invention can adjust the position of guide wheel by rotating bar, can be realized the tune to rotating bar by adjusting component Section, can lock or unlock sliding block by jackscrew, slided by sliding block and drive connecting rod to drive rotating bar, passed through Nut in fixing axle realize to rotating bar, connecting rod, sliding block axial limiting, the present invention is easy for installation, can pass through guide wheel Guiding avoid the disengaging of chain Yu drive sprocket, driven sprocket.
Detailed description of the invention
Fig. 1 is main view of the invention;
Wherein:
1 chain pin of carrier bar 2 I
3 No. II 4 lateral guide grooves of chain pin
5 sliding block, 6 fixing axle

Specific embodiment
Hereinafter, referring to drawings and examples, the present invention is described in detail:
As shown in Figure 1, a kind of Novel chain structure, including multiple link units, the link units include two blocks of carrier bars 1, consolidate 1, No. II chain pin 3 of No. I chain pin being scheduled on carrier bar 1 and the axle sleeve on 1, No. II chain pin 3 of No. I chain pin is covered, 1 outside of carrier bar It is provided with the rotating bar 7 of rotation, the free end of the rotating bar 7 is provided with guide wheel 10, and adjusting is provided on the outside of the carrier bar 1 and is turned The adjusting component of 7 rotational angle of lever.
It is provided with fixing axle 6 on the outside of the carrier bar 1, forms through-hole in the rotating bar 7, the fixing axle 6 is inserted into logical Kong Zhong.
The free end of the fixing axle 6 is provided with the nut for avoiding rotating bar 7 from skidding off.
The turning end of the rotating bar 7 is provided with bracket 9, and the guide wheel 10 is arranged in bracket 9.
The bracket 9 is vertical with rotating bar 7.
The component that adjusts includes the lateral guide groove 4 at 1 outer wall of carrier bar, and the cunning of sliding is provided in the lateral guide groove 4 Block 5,5 outer wall of sliding block are hinged with connecting rod 8, and 8 other end of connecting rod and rotating bar 7 are hinged.
The guide wheel 10 leans out 1 lower end of carrier bar.
The jackscrew 11 of fixed sliding block 5 is provided at 5 outer wall of sliding block.
It is clearance fit between the sliding block 5 and lateral guide groove 4, the lateral guide groove 4 is located at 1, No. II chain pin of No. I chain pin Between 3.
The chain is made of multiple link units, and the chain is driven by drive sprocket and driven sprocket.The active Guide rail is provided between sprocket wheel, driven sprocket, the length of the guide rail is less than between the axial direction between drive sprocket, driven sprocket Away from.
