Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a rubber sealing ring. Background Technology

[0002] Sealing rings are primarily used to achieve the function of sealing and preventing leakage. Depending on the application, they can be divided into hole sealing rings, shaft sealing rings, and dust seals, etc.

[0003] However, existing rubber seals are usually injection molded using injection molding molds. During the process of separating the rubber seal from the injection molding mold after molding, due to design defects, operators may get their hands cut during demolding, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this utility model is to provide a rubber sealing ring to solve the problem mentioned in the background art that existing rubber sealing rings are usually injection molded by injection molding molds. However, due to design defects of the rubber sealing ring, operators may be cut during the demolding process, resulting in poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber sealing ring, comprising a sealing ring body, wherein a plurality of sealing rings are fixedly connected to the outer wall surface of the sealing ring body, guide circles are provided at the connection between the upper and lower end faces of the sealing rings and the sealing ring body, a plurality of through holes are provided on the surface of the sealing ring body, and an annular chamfer is provided on the surface of the sealing ring body at the opening of the through hole, and protrusions are fixedly distributed and connected to the surface of the sealing ring body around the through holes.

[0006] Preferably, the sealing ring body and the sealing ring are integrally molded.

[0007] Beneficial effects

[0008] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0009] By incorporating the structural design of this utility model, guide circles are provided at the connection points between the upper and lower ends of the sealing ring and the sealing ring body. This effectively prevents the operator from getting their hands cut during the process of the rubber sealing ring separating from the injection molding mold after injection molding, thus improving operational safety and enhancing practicality.

[0013] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] like Figure 1-2 This is a schematic diagram of a preferred embodiment of the present invention. In this embodiment, a rubber sealing ring includes a sealing ring body 1, and several sealing rings 2 are fixedly connected to the outer wall surface of the sealing ring body 1. Guide circles 6 are provided at the connection between the upper and lower end faces of the sealing rings 2 and the sealing ring body 1. With the above design, by providing guide circles 6, the rubber sealing ring can effectively prevent the operator's hand from being cut during the process of separating from the injection molding mold after injection molding, thereby improving the safety of operation and making it more practical.

[0016] In this embodiment, the sealing ring body 1 has several through holes 3 on its surface, and the sealing ring body 1 has an annular chamfer 4 at the opening of the through hole 3. This structural design is intended to facilitate the insertion of the fittings and to serve as a guide.

[0017] In this embodiment, the sealing ring body 1 has protrusions 5 evenly distributed and fixedly connected around the through hole 3. This design increases the friction between the protrusions and the surface of the sealing ring body 1, preventing misalignment and deformation.

[0018] In this embodiment, the sealing ring body 1 and the sealing ring 2 are integrally molded. This structural design improves the connection strength between the sealing ring body 1 and the sealing ring 2, and ensures their sealing performance.

[0019] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
