Solve above-described technical problem, the technological scheme that the utility model is taked is:
The utility model is a kind of exhaust purifier linkage structure, comprises the clip being connected with purifier, and described purifier also comprises support, and described hoop sleeve is contained on purifier, one end of support and clip connected, and the other end of support is connected with speed changer.
Preferably, described hoop sleeve is contained on the outlet pipe of purifier, and the two end part of clip respectively arrange an attachment hole, and the two end part of support respectively arrange a bolt through-hole, passes the bolt of two attachment holes and a bolt through-hole by support and clip connected simultaneously.
Preferably, one of them bolt through-hole arranged outside projection welding square nut of described support is connected with projection welding square nut through the bolt of two attachment holes and a bolt through-hole simultaneously.
Preferably, two attachment holes at the two end part of described clip are all set to waist-shaped hole structure, described bolt through-hole comprises bolt through-hole I and bolt through-hole II, and bolt through-hole I is by bolt and clip connected, and bolt through-hole II is connected with gearbox by connecting bolt.
Preferably, described projection welding square nut is connected by welding manner with support.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Exhaust purifier linkage structure of the present utility model, the coupling stiffness of purifier and support is high, support coordinates with project-welding nut by the bolt on clip, directly suit is connected on outlet pipe, attachment hole on clip is set to waist-shaped hole structure, makes support in installation process, have certain adjustment space, has avoided rigidity that the impact of the stress producing on exhaust purifier is installed, make the fixing more firm of exhaust purifier, extended the working life of exhaust purifier and support.Meanwhile, project-welding nut is directly welded on support, greatly cost-saving and shortening installation time, thus improve efficiency of assembling, alleviate workman's assembling difficulty.
