Description

Technical Field

[0001] The utility model relates to the field of flange accessories, in particular to a flange retaining ring with a dustproof function. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used on the inlet and outlet of equipment to connect two devices. When the flange is used, it needs to be equipped with a retaining ring to complete the seal.

[0003] However, the flange retaining rings currently in use have poor applicability due to their poor sealing effect. Utility Model Content

[0004] The purpose of the utility model is to provide a flange retaining ring with a dustproof function in order to solve the problem that the current sealing effect is not good and the applicability thereof is poor.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a flange retaining ring with dustproof function, comprising a flange, a retaining ring being sleeved on the outer side of the flange, an airbag being provided on the outer side of the retaining ring, and a rubber plate being provided on the inner wall of the retaining ring.

[0006] As a further solution of the present invention: an anti-wear layer is provided on the outer side of the airbag, and the thickness of the airbag is greater than the height of the retaining ring.

[0007] As a further solution of the present invention: through holes are evenly arranged on the surface of the retaining ring, and the retaining ring is made of metal.

[0008] As a further solution of the present invention: the surface of the flange is evenly provided with mounting holes.

[0009] As a further solution of the present invention: the height of the rubber plate is greater than the height of the retaining ring, and the center position of one side of the rubber plate is connected to the retaining ring.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. By setting an airbag on the outside of the retaining ring, the height of the airbag is also greater than the thickness of the retaining ring. At this time, when the flange is connected, the airbag will be gradually squeezed to deform, and at the same time it can adapt to the unevenness of the connection, and at the same time achieve the purpose of primary sealing. The retaining ring itself completes the purpose of secondary sealing, making the dustproof effect better. At the same time, a rubber plate is set inside the retaining ring to be able to deform, and the retaining ring itself can be limited to prevent the retaining ring itself from moving and affecting the sealing effect during the connection.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figures 1 to 3 In an embodiment of the utility model, a flange retaining ring with a dustproof function includes a flange 1, a retaining ring 2 is sleeved on the outer side of the flange 1, an air bag 3 is provided on the outer side of the retaining ring 2 to achieve a sealing effect, and a rubber plate 4 is provided on the inner wall of the retaining ring 2, which can be deformed to keep the retaining ring 2 always in the center position.

[0018] In this embodiment, the airbag can be deformed by squeezing during connection, so that the connection can be sealed once. The rubber plate 4 can be deformed when the retaining ring 2 is sleeved, so that the retaining ring 2 is always in the center position.

[0019] Please refer to Figure 1 An anti-wear layer is provided on the outside of the airbag 3 to prevent the airbag 2 from rupturing due to wear during connection, and the thickness of the airbag 3 is greater than the height of the retaining ring 2. The airbag 3 can be deformed due to extrusion, and the deformed airbag 3 has the same thickness as the retaining ring 2.

[0020] In this embodiment, the anti-wear layer is provided to increase the service life of the airbag 3 , and the deformation of the airbag 3 can seal the connection.

[0021] Please refer to Figure 1 The surface of the ring 2 is evenly provided with through holes, which can reduce the weight of the overall retaining ring, and the retaining ring 2 is made of metal, which is harder and not easy to deform.

[0022] In this embodiment, the weight can be reduced by providing the through holes, and the hardness of the entire retaining ring 2 can be increased, making it less likely to deform.

[0023] Please refer to Figure 1 and 2 The surface of the flange 1 is evenly provided with mounting holes. After the installation of the flange 1 is completed, the height of the rubber plate 4 is greater than the height of the retaining ring 2, and the center position of one side of the rubber plate 4 is connected to the retaining ring. When connected, the top and bottom ends of the rubber plate 4 can be deformed to achieve sealing.

[0024] In this embodiment: when installing the retaining ring 2, the retaining ring 2 is rotated while holding the connection with the extrusion flange 1. At this time, the rubber plate 4 is deformed to the same side, and the top and bottom ends of the rubber plate 4 are folded inward to achieve a good sealing effect.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
