Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to imply that the number of technical features indicated is significant. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1, a universal radial seal ring includes: sealing washer body 1, funnel structure 3 sets up in the sealing washer body 1, carry out one-way seal to the article that pass through, adsorption structure 2 connects the bottom surface of 1 outer loop of sealing washer body through the adsorption structure 2 that sets up, can adsorb sealing washer body 1 on the human body, make between sealing washer body 1 and the human body laminating inseparabler, prevent that outside foul or bacterium from getting into sealing washer body 1 and human division department, reduce the risk in the operation process, completely cut off external environment as far as possible
