[0033] The utility model provides an antibacterial sealing ring 100 .

[0034] See also Figures 1 to 4 In one embodiment of the utility model, the antibacterial sealing ring 100 includes a sealing ring body 1, an antibacterial ring 2 and an adsorption ring 3; a first annular groove 11 is formed on the inner peripheral wall of the sealing ring body 1, a first positioning groove 12 is formed at the bottom of the first annular groove 11, a second annular groove 13 is formed on one side of the sealing ring body 1, and a second positioning groove 14 is formed at the bottom of the second annular groove 13; the antibacterial ring 2 includes an antibacterial ring 2 body and a first positioning block 21 provided on the outer peripheral wall of the antibacterial ring 2 body, the antibacterial ring 2 body is embedded in the first annular groove 11, and the first positioning block 21 is plugged into the first positioning groove 12; the adsorption ring 3 includes an adsorption ring 3 body and a second positioning block 31 provided on one side of the adsorption ring 3 body, the adsorption ring 3 body is embedded in the second annular groove 13, and the second positioning block 31 is plugged into the second positioning groove 14.

[0035] In the technical solution of the utility model, firstly, by embedding the antibacterial ring 2 and the adsorption ring 3 on the sealing ring body 1, the antibacterial effect is ensured, and the adsorption ring 3 can absorb the odor, so that the antibacterial sealing ring 100 has a deodorizing function. Secondly, by the cooperation between the first positioning groove 12 and the first positioning block 21 and the cooperation between the second positioning groove 14 and the second positioning block 31, the antibacterial ring 2 and the adsorption ring 3 are stably installed and not easy to be separated, and are convenient for replacement. Thirdly, the antibacterial ring 2 is arranged on the inner peripheral wall of the sealing ring body 1, and the adsorption ring 3 is arranged on one side of the sealing ring body 1, which can effectively reduce the thickness of the sealing ring body 1, so that it can be applied to more usage environments.

[0036] In order to ensure stable installation, in one embodiment of the present utility model, please refer to Figure 2The antibacterial ring 2 includes a plurality of first positioning blocks 21, which are arranged in an annular array on the outer peripheral wall of the main body of the antibacterial ring 2; a plurality of first positioning grooves 12 are formed at the bottom of the first annular groove 11, and each first positioning block 21 is plugged into a first positioning groove 12. In this way, the antibacterial ring 2 can be limited by the cooperation of the plurality of first positioning blocks 21 and the plurality of first positioning grooves 12 at the same time, so that the antibacterial ring 2 is more stable when installed on the sealing ring main body 1. Among them, the number of the first positioning blocks 21 and the first positioning grooves 12 can be three, four, five, etc., the number of the first positioning blocks 21 and the first positioning grooves 12 can be the same, or the number of the first positioning grooves 12 can be more than the number of the first positioning blocks 21 and the first positioning grooves 12.

[0037] It is understandable that, since the first positioning groove 12 is located at the bottom of the first annular groove 11, it is not convenient to observe the position of the first positioning groove 12 when installing the antibacterial ring 2. Therefore, in one embodiment of the utility model, please refer to Figure 1 An indicator portion 15 is formed on one side of the sealing ring body 1. The indicator portion 15 is arranged corresponding to the first positioning groove 12. By observing the position of the indicator portion 15, the position of the first positioning groove 12 can be known, so as to facilitate the installation of the antibacterial ring 2. When there are multiple first positioning grooves 12, the indicator portion 15 can be arranged in multiple corresponding positions. When the first positioning grooves 12 are evenly distributed, only one indicator portion 15 can be arranged.

[0038] Specifically, in one embodiment of the present invention, the indicating portion 15 is an indicating groove. In another embodiment of the present invention, the indicating portion 15 is an indicating protrusion.

[0039] In order to ensure stable installation, in one embodiment of the present utility model, please refer to Figure 2 , the adsorption ring 3 includes a plurality of second positioning blocks 31, which are arranged in an annular array on one side of the main body of the adsorption ring 3; a plurality of second positioning grooves 14 are formed at the bottom of the second annular groove 13, and each second positioning block 31 is plugged into a second positioning groove 14. In this way, the adsorption ring 3 can be limited by the cooperation of the plurality of second positioning blocks 31 and the plurality of second positioning grooves 14 at the same time, so that the adsorption ring 3 is more stable when installed on the sealing ring main body 1. Among them, the number of the second positioning blocks 31 and the second positioning grooves 14 can be three, four, five, etc., the number of the second positioning blocks 31 and the second positioning grooves 14 can be the same, or the number of the second positioning grooves 14 can be more than the number of the second positioning blocks 31 and the second positioning grooves 14.

[0040] Further, in an embodiment of the utility model, the first positioning groove 12 and the second positioning groove 14 are staggered along the axial direction of the sealing ring body 1. When the groove depth of the first positioning groove 12 and the groove depth of the second positioning groove 14 are both large, if the first positioning groove 12 and the second positioning groove 14 overlap along the axial direction of the sealing ring body 1, it may cause the first positioning groove 12 to communicate with the second positioning groove 14, so that when the antibacterial ring 2 and the adsorption ring 3 are installed, the first positioning block 21 and the second positioning block 31 interfere and cannot be installed. Considering this point, the first positioning groove 12 and the second positioning groove 14 are staggered along the axial direction of the sealing ring body 1 to adapt to antibacterial rings 2 and adsorption rings 3 of different specifications.

[0041] Further, in an embodiment of the present utility model, please refer to Figure 3 From the notch of the first positioning groove 12 to the bottom of the first positioning groove 12, the cross-sectional area of ​​the first positioning groove 12 gradually increases, so that when the first positioning block 21 is inserted into the first positioning groove 12, it is easy to install and difficult to disassemble, making the connection between the antibacterial ring 2 and the sealing ring body 1 more stable.

[0042] Further, in an embodiment of the present utility model, please refer to Figure 4 From the notch of the second positioning groove 14 to the bottom of the second positioning groove 14, the cross-sectional area of ​​the second positioning groove 14 gradually increases, so that when the first positioning block 21 is inserted into the first positioning groove 12, it is easy to install and difficult to disassemble, making the connection between the adsorption ring 3 and the sealing ring body 1 more stable.

[0043] Specifically, in an embodiment of the present invention, the main body of the antibacterial ring 2 and the first positioning block 21 are integrally formed to facilitate production. Similarly, the main body of the adsorption ring 3 and the second positioning block 31 are integrally formed.

[0044] In order to adapt to high temperature environment, in one embodiment of the present utility model, please refer to Figure 1 The antibacterial sealing ring 100 further comprises a high temperature resistant layer 4, which is arranged on the outer peripheral wall of the sealing ring body 1. The heat resistance of the antibacterial sealing ring 100 can be improved by arranging the high temperature resistant layer 4. The material of the high temperature resistant layer 4 is polyamide ester fiber.

[0045] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
