[0021] The technical scheme in the utility model embodiment will be clearly and completely described below with reference to the drawings in the utility model embodiment. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Refer to Figures 1-4The utility model provides a kind of liquid filter system type gasket, including annular plate, annular limiting plate 3 is installed along the inside and outside of annular plate, limiting plate 3 is the rubber with elasticity, it needs to be explained that in liquid filter system, pipe needs to be used to be connected to filter device, let the liquid to be filtered can be filtered into, thus when being connected installation to pipe, the gasket can be taken and placed between two pipes, let the pipe placed between limiting plate 3 can be subjected to the elastic action of limiting plate 3, so that limiting plate 3 is tightly attached on the pipe wall of pipe, to be connected between two pipes is wrapped, improve the sealing property after the annular plate is placed between two pipes, wherein, first arc section 9 is provided at the side edge of two rubber plates 1 close to limiting plate 3, after being placed in limiting plate 3, the edge of pipe opening can extrude first arc section 9, so that limiting plate 3, annular plate better adhere to pipe opening.

[0023] As shown in the figure, Figure 4 The annular plate includes annular support plate 2, and elastic annular rubber plate 1 is arranged on the upper and lower sides of the support plate 2. The edges of the two rubber plates 1 are fixedly connected to each other to wrap the support plate 2. The two limiting plates 3 are vertically fixed on the inner and outer sides of the rubber plates 1, so that the annular plate can deform and generate elastic force after being pressed to act on the pipe. Thus, after the two pipes are fixed, the close effect of the annular plate on the pipe opening can be improved.

[0024] As shown in the figure, Figure 4 When the gasket is taken and placed between the two pipes, the pipe opening approaches the limiting plate 3. Annular elastic spring 4 is coaxially arranged on the upper and lower sides of the limiting plate 3. The elastic spring 4 is wrapped with elastic rubber sleeve 5. A plurality of spaced-apart grooves 7 are formed in the elastic spring 4, and the grooves 7 penetrate the rubber sleeve 5. The thickness of the rubber sleeve 5 is less than the thickness of the limiting plate 3. The front view projection position of the elastic spring 4 is located in the middle of the limiting plate 3. When the pipe approaches the limiting plate 3, the pipe opening will first contact the rubber sleeve 5, so as to limit the process of the pipe opening falling into the limiting plate 3, and the pipe opening can accurately fall into the limiting plate 3. When the axis of the pipe opening deviates from the axis of the rubber sleeve 5, the pipe opening will act on the rubber sleeve 5, so as to extrude the rubber sleeve 5. With the insertion of the pipe opening into the limiting plate 3, the second arc section 6 is arranged at the edge of the limiting plate 3 and the side edge of the elastic spring 4 close to the limiting plate 3. Adjacent two second arc sections 6 are tangent to each other. Because the shape of the limiting plate 3 is fixed, when the pipe opening contacts the end of the limiting plate 3, the subsequent insertion of the pipe can be guided, so that the pipe body can stably slide into the limiting plate 3. Thus, it is ensured that the pipe opening can accurately fall into the limiting plate 3. With the pipe opening falling into the limiting plate 3, the deformation degree of the elastic spring 4 will continuously deepen, and the elastic force of the elastic spring 4 will continuously increase. The elastic spring 4 can rebound to restore the initial state.

[0025] Specifically, the slot 7 is a tapered slot arranged near the limiting plate 3, so that the rubber sleeve 5 is segmented by the slot 7, and the mutual influence between the rubber sleeves 5 is reduced, thereby affecting the rebound of the rubber sleeve 5 after deformation.

[0026] Further, the side of the elastic sheet 4 away from the limiting plate 3 is curved towards the rubber plate 1, so that after the pipe opening falls into the limiting plate 3, the rubber sleeve 5 can be attached to the outer wall of the pipe to wrap the pipe.

[0027] It should be noted that a plurality of annular rubber rings 8 are installed on the side of the two limiting plates 3 relatively close to each other, and the rubber rings 8 are coaxially arranged with the limiting plate 3, so that after the pipe is placed in the limiting plate 3, the limiting plate 3 is fastened on the pipe, and the sealing performance of the gasket is improved.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
