A compressible rubber seal

Abstract

The invention discloses a rubber sealing ring with compressibility. The rubber sealing ring with the compressibility comprises an upper sealing part and a lower sealing part, and a compression part isconnected between the upper sealing part and the lower sealing part in a glued mode. An upper extrusion layer is arranged on the upper end surface of the compression part, and a lower extrusion layeris arranged on the lower end surface of the compression part. An elastic convex strip is connected in a round between the upper extrusion layer and the lower extrusion layer, and friction lines are arranged on the inner surface of the elastic convex strip. The rubber sealing ring with the compressibility is provided with the compression part, a cleaning small hairbrush and a dust cleaning net, the elastic convex strip is enabled to extend inwards by compression, the tightness being in contact with an internal shaft is increased, the sealing effect of the sealing ring is improved, the hairbrush is used for wiping dust or oil stains on the shaft to achieve a clean effect, meanwhile, the dust is adsorbed in a concentrated mode through the dust cleaning net, the dust cleaning effect is improved, the service life of the sealing ring is prolonged, the sealing ring is suitable for different working conditions, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of sealing rings, in particular to a compressible rubber sealing ring. Background technique [0002] The sealing ring is used to be installed on various mechanical equipment, and plays a sealing role in the static or moving state under the specified temperature and pressure, as well as different liquids and gases. There are many types and shapes; the existing rubber sealing rings are in use There are certain disadvantages at the time. The contact tightness between the ordinary O-ring and the shaft is average, and the sealing effect needs to be strengthened. At the same time, the general rubber sealing ring does not have the function of cleaning dust, resulting in dust and oil stains at the position of the shaft and the sealing ring. Accumulation and untidyness will also affect the use of accessories, which will bring certain adverse effects during use. For this reason, we propose a rubber sealing ring with compressibi...
