Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing rings, in particular to a magnetic sealing ring. Background Art
[0002] The choice of sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring. The V-shaped sealing ring is an axially acting elastic rubber sealing ring, which is used as a pressure-free seal for rotating shafts. The sealing lip has good mobility and adaptability, can compensate for large tolerances and angular deviations, can prevent internal grease or oil from leaking out, and can also prevent splashing water or dust from invading from the outside.
[0003] Magnetic sealing rings are mostly used in V-shaped sealing ring structures. Common magnetic sealing rings are similar to the sealing strips of refrigerators. During the use of magnetic sealing rings, their magnetism gradually fades with the increase of usage time until they can no longer exert their magnetic attraction ability, but they are inconvenient to replace. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a magnetic sealing ring which can be magnetized and is easy to operate and has a long service life.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A magnetic sealing ring comprises a sealing ring body, a magnet, a magnetizing coil, a magnetizing interface and a detachable protective ring. The sealing ring body is provided with a magnet inside, the surface of the magnet is wound with a magnetizing coil, the magnetizing coil is connected to the magnetizing interface, and the detachable protective ring can be sleeved on the sealing ring body.
[0007] Furthermore, a protective cover is provided at the magnetization interface.
[0008] The beneficial effects of the utility model are as follows: in actual use, the sealing ring body is used to provide sealing support, the magnet is used to provide magnetic fixing support, the magnetizing coil is used to magnetize the magnet, the magnetizing coil is powered through the magnetizing interface, and the detachable protective ring is used to protect and seal the magnetizing interface to prevent the magnetizing interface from being exposed to the outside, and at the same time, it is easy to disassemble when the magnetizing operation is required. The magnetic sealing ring of the present application can be magnetized, and the operation is convenient, which increases the service life. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the utility model.
[0010] Description of the reference numerals: sealing ring body 1 , magnetizing interface 2 , protective cover 21 , detachable protective ring 3 . DETAILED DESCRIPTION
[0011] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.
[0012] like Figure 1 As shown, the utility model provides a magnetic sealing ring, which includes a sealing ring body 1, a magnet, a magnetizing coil, a magnetizing interface 2 and a detachable protective ring 3. The sealing ring body 1 is provided with a magnet inside, the surface of the magnet is wound with a magnetizing coil, the magnetizing coil is connected to the magnetizing interface 2, and the detachable protective ring 3 can be sleeved on the sealing ring body 1.
[0013] In actual use, the sealing ring body 1 is used to provide sealing support, the magnet is used to provide magnetic fixing support, the magnetizing coil is used to magnetize the magnet, the magnetizing coil is powered through the magnetizing interface 2, and the detachable protective ring 3 is used to protect and seal the magnetizing interface 2 to prevent the magnetizing interface 2 from being exposed to the outside, and to facilitate disassembly operation when magnetizing operation is required.
[0014] A magnetic sealing ring of the present application can be magnetized, is easy to operate, and has a longer service life.
[0015] like Figure 1 As shown, in this embodiment, a protective cover 21 is provided at the magnetizing interface 2. In actual use, the magnetizing interface 2 is protected by the protective cover 21 to prevent it from contacting the outside world and to prevent water and dust.
[0016] All technical features in this embodiment can be freely combined according to actual needs.
[0017] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
