Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
referring to fig. 1-5, the utility model provides a three way catalyst housing, including coarse shell 1, fine shell 2 and connector 3, coarse shell 1, fine shell 2, connector 3 swing joint, the port of coarse shell 1 is equipped with main ball cover 101, and the port of fine shell 2 is equipped with vice ball cover 201, and connector 3 includes siphunculus and spherical shell 301, the both ends body coupling spherical shell 301 of siphunculus, and spherical shell 301 difference movable mounting is in main ball cover 101 and vice ball cover 201.
Specifically, the through pipe is not in contact with the edge openings of the main ball sleeve 101 and the auxiliary ball sleeve 201, so that the phenomenon that the thick shell 1, the thin shell 2 and the connector 3 are clamped in a rotating mode is avoided, the rotating amplitude is reduced, and the rotation is limited.
Specifically, as shown in fig. 1, the spherical shell 301 is provided with an air vent for facilitating the passage of the exhaust gas.
Specifically, the diameter length of the vent hole is smaller than the diameter length of the port of the main ball sleeve 101 and the port of the auxiliary ball sleeve 201, so that the vent hole can be always positioned in the main ball sleeve 101 and the auxiliary ball sleeve 201 when the coarse shell 1, the fine shell 2 and the connector 3 rotate mutually, shielding is minimum, and tail gas is maximally passed through.
Specifically, as shown in fig. 3, one end of the thin shell 2 is provided with an auxiliary ball sleeve 201 or two ends of the thin shell 2 are provided with auxiliary ball sleeves 201, so that the thin shell 2 can be twisted and deformed.
The working principle is as follows:
the assembly is divided into three conditions;
firstly, transversely connecting and assembling a coarse shell 1 and a fine shell 2, respectively placing a ball shell 301 of a connector 3 in a main ball sleeve 101 and an auxiliary ball sleeve 201, after the coarse shell 1 and the fine shell 2 are welded and spliced, positioning the connector 3 at the joint of the coarse shell 1 and the fine shell 2, and straightening the whole device for use;
secondly, the thin shell 2 is assembled obliquely to the thick shell 1, the thin shell 2 and the connector 3 are assembled according to the first mode, when the connector is used, the main ball sleeve 101, the ball shell 301, the auxiliary ball sleeve 201 and the ball shell 301 can rotate mutually, because the ball sleeve is adopted, the moving range is large, the angle is large, and after the oblique position of the thin shell 2 is freely selected, the rotation of the thin shell 2 is realized through the rotation operation;
thirdly, the body of the thin shell 2 needs to be bent in multiple sections, in this case, the two ends of the thin shell 2 are provided with the auxiliary ball sleeves 201 (refer to fig. 3), and the connector 3 is assembled between the thin shells 2 for use, so that each section of the thin shell 2 can be adjusted in direction;
in the three assembling modes, the air flow channel of the assembly body is required to be kept free from blockage and leakage, namely, the air vent of the spherical shell 301 is communicated with the air channels of the coarse shell 1 and the fine shell 2.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
