Slidable spacer for exhaust pipe

Abstract

The invention discloses a slidable spacer for an exhaust pipe. The slidable spacer comprises at least two spacer bodies, wherein each spacer body is provided with an exhaust hole and a screw hole, the position between the exhaust hole and the screw hole of at least one spacer body is of an outward protruding convex structure, at least one end of the position between every two spacer bodies is provided with a gap, the convex structure is provided with a mounting platform, and the surfaces of the spacer bodies are provided with molybdenum disulfide coatings. The slidable spacer can slide relative to the exhaust pipe to absorb a certain thermal deformation of the exhaust pipe, and therefore the exhaust pipe is prevented from cracking and leaking gas. Moreover, as the surfaces of the spacer bodies are provided with the molybdenum disulfide coatings, the sliding effect of the slidable spacer can be improved.

Description

technical field [0001] The invention relates to a gasket, in particular to a slidable gasket for an exhaust pipe. Background technique [0002] At present, the temperature of the exhaust system of the automobile engine is relatively high, and there will be a large thermal deformation for the exhaust pipe directly contacting the high-temperature gas of the engine. For two vertically connected exhaust pipes, if the thermal deformation of the exhaust pipes cannot be well absorbed, the exhaust pipes will crack and leak due to the excessive thermal stress of the exhaust pipes. Contents of the invention [0003] The object of the present invention is to provide a slidable spacer for an exhaust pipe which has a simple structure and can absorb thermal deformation of the exhaust pipe in order to overcome the above disadvantages. [0004] The present invention includes a gasket body provided with vent holes and screw holes, including at least two gasket bodies, and at least one gas...
