Abstract
The utility model provides a rubber cylinder gasket. The rubber cylinder gasket comprises a rubber gasket and a metal framework arranged inside the rubber gasket, wherein a through hole is formed in the center of the rubber gasket, semicircular grooves are uniformly distributed in the outer edge of the rubber gasket, and annular grooves are formed in the upper end surface and the lower end surface of the rubber gasket. The rubber cylinder gasket is made of rubber, and the metal framework with a galvanized surface is embedded inside rubber, so that the strength of the rubber cylinder gasket is increased, and the service life of the rubber cylinder gasket is prolonged. Moreover, the rubber cylinder gasket is easy to machine, and at least two annular grooves are formed in the surface of the rubber cylinder gasket, so that the sealing performance of the rubber cylinder gasket can be greatly improved. The rubber cylinder gasket is simple in structure, convenient to machine, good in sealing effect, long in service life, and suitable for mass production.
Description
Technical field
The utility model relates to a kind of automobile pad, particularly a kind of rubber casing pad.
Background technique
Traditional automobile exhaust pad generally adopts the mode of spot welding behind the metal plain film beading or rivet combination to reach sealing effect.Metal material guarantees that product can reach the effect of heatproof in working environment.Beading generally adopts dual mode, and a kind of is full convex tendon, and a kind of is semi-convex muscle.No matter be full convex tendon and semi-convex muscle, all be by suppressing convex tendon circular arc or ladder-type at tinsel, the elasticity by convex tendon reaches sealing effect.But adopt the sheeting material beading, shaping operation is easy, but product strength is low.Adopt sheet material beading, product strength height, but shaping operation difficulty are difficult to guarantee the flatness of product, influence sealing effect thereby influence product in the installation using process, greatly reduce working life.
