Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, provide a kind of simple in structure, avoid ternary catalyzing unit fracture, the ternary catalystic device structure reducing costs in motor-driven vehicle going process.
Solve above-described technical problem, the technological scheme that the present invention takes is:
The present invention is a kind of ternary catalystic device structure, comprise catalyst converter housing, end cone, each is fixedly connected with described catalyst converter housing two end part with an end cone, described catalyst converter housing is tubular structure, two termination portions of catalyst converter housing respectively arrange kink I, and two end cones respectively arrange a kink II, and catalyst converter housing links together with two kink II spiral-locks of two end cones respectively by two kink I.
Preferably, two kink I of two termination portions of described catalyst converter housing are bending to the inside respectively, two kink I are parallel with inner walls, the bending laterally respectively of two kink II of two described end cones, two kink II are set to respectively the structure parallel with holding cone outer wall, and described catalyst converter housing is welded by frame set I and frame set II.
Preferably, when described catalyst converter housing is fixedly connected with end cone, the structure that the inner walls of described catalyst converter housing and kink I and kink II are set to fit together, described kink I bores with end the structure that outer wall is set to fit together.
Preferably, on the end cone outer wall of described catalyst converter structure, be also provided with the positive stop strip that twice are protruded, two positive stop strips are set to respectively along the structure of two end cone outer walls setting in a week, the structure that two described positive stop strips fit together with the bending end head of two kink I respectively.
Adopt technological scheme of the present invention, can obtain following beneficial effect:
Ternary catalystic device structure of the present invention, simple in structure, described ternary catalystic device structure comprises a catalyst converter housing and two end cones, two termination portions of catalyst converter housing respectively arrange kink I, two end cones respectively arrange a kink II, and catalyst converter housing links together with two kink II spiral-locks of two end cones respectively by two kink I.Described catalyst converter housing is divided into frame set I and frame set II, after catalyst converter housing is connected with two kink II of two end cones respectively by two kink I, again frame set I and frame set II are welded together, such structural strengthening the join strengths between two end cones and catalyst converter housing, in motor-driven vehicle going process, even if vent systems is through shake and vibration for a long time, ternary catalyzing unit also not can or rare cracking or disconnection, thereby can not affect travelling of Motor Vehicle, and the minimizing of ternary catalyzing unit damage probability, also reduced Motor Vehicle maintenance cost.
