Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a sealing ring with dust-proof surface. Background Technique

[0002] A sealing ring is a mechanical component used for sealing, usually made of rubber, plastic or metal materials, and is widely used in various industries and equipment, such as automobiles, machinery, household appliances, etc. Its main function is to prevent leakage of liquids, gases or other substances, and to isolate the external environment;

[0003] During the use of the sealing ring, the use environment is complex, and it is often necessary to achieve the effect of dust prevention, such as:

[0004] In the prior art, a Chinese patent with the authorization announcement number of CN213419868U discloses a dust-proof sealing ring. Through a special structural design, it solves the problem that during the repeated use process, the rubber is prone to deformation, and it is impossible to completely seal the gap between two sets of rings or washers, resulting in poor dust-proof effect. In this application, when the ring body is deformed during repeated use, the elastic piece drives the support block to push the ring body to deform outward under its own acting force, so that the ring body abuts against the bearing ring or washer, and continues to seal the gap between them, improving the service life of the sealing ring and enhancing the dust-proof property of the sealing ring.

[0005] Through the above device, it can be seen that in the prior art, generally, better dust-proof effect is achieved by increasing the overall sealing performance. However, in the actual use process, there will be a certain friction between the machine equipment and the sealing ring during use. Since the sealing ring is made of insulating rubber material, a certain amount of static electricity will be accumulated. The static electricity makes dust adsorb on the surface of the sealing ring, increasing the possibility of dust entering. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sealing ring with dust-proof surface to solve the problem that dust is adsorbed by static electricity and increases the possibility of entering the sealing ring as mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A sealing ring with dust-proof surface, including a sealing ring main body in a ring structure, an installation groove for clamping the installation position is opened inside the sealing ring main body, and further includes:

[0008] An outer convex lip is fixedly installed on the outer surface of the sealing ring main body, and an inner convex lip fixedly installed with the sealing ring main body is arranged at the lower end inside the installation groove;

[0009] A dust-proof pad is fixedly installed on the upper surface of the sealing ring main body, and the dust-proof pad is in a ring structure, and the inner diameter of the inner ring of the dust-proof pad is the same as the inner diameter of the inner ring of the sealing ring main body.

[0010] Preferably, both the outer convex lip and the inner convex lip are made of soft rubber material, and the inner convex lip is an inclined annular structure.

[0011] Preferably, the upper surface of the dust-proof pad is sprayed with a smooth paint surface, and an annular isolation ring is fixedly installed on the upper surface of the inner ring of the dust-proof pad.

[0012] Preferably, a metal mesh is fixedly installed on the lower surface of the dust-proof pad, and the metal mesh fits the device to conduct static electricity.

[0013] Preferably, support ribs fixedly installed on the inner wall of the sealing ring body are provided at the upper and lower ends inside the installation groove.

[0014] Preferably, the support ribs are arranged in an annular structure corresponding to the sealing ring body, and the support ribs are made of plastic material with a supporting effect.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sealing ring for surface dust prevention adopts a new structural design, and the specific content is as follows:

[0016] 1. The sealing ring body is installed at the position to be sealed in the device through the installation groove opened inside the sealing ring body. At this time, the inner convex lip and the outer convex lip on both the inner and outer sides of the sealing ring body are closely attached to the device, achieving an effective sealing effect.

[0017] Further, a dust-proof pad is arranged above the sealing ring body to prevent dust from entering the inside of the sealing ring and affecting the normal use of the sealing ring. Moreover, an isolation ring is fixedly arranged above the inner ring of the dust-proof pad, and a better dust-proof effect can be achieved by using the isolation ring.

[0018] Furthermore, a metal mesh is fixedly installed on the lower surface of the dust-proof pad. By using the conductive function of the metal mesh, the static electricity generated by friction in the dust-proof pad can be quickly conducted out, thereby avoiding dust accumulation caused by static electricity adsorption of dust.

[0019] 2. Support ribs are arranged inside the sealing ring body to maintain the shape of the sealing ring body and prevent the sealing ring body from deforming during long-term use and affecting the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS
