DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution for a high-pressure sealed bearing: its structure includes a bearing body 1, a sealing ring 2 is arranged around the bearing body 1, the bearing body 1 is composed of a bearing outer ring 3, a bearing inner ring 4 and a ball 5 located between the bearing outer ring 3 and the bearing inner ring 4, sealing cover plates 6 are provided on both sides of the bearing body 1, the sealing cover plates 6 are connected to the sealing ring 2, sealing strips 7 are arranged on the bearing outer ring 3 and the bearing inner ring 4, the sealing strip 7 is arranged around the bearing outer ring 3 and the bearing inner ring 4, a sealing ring strip 601 is arranged on the sealing cover plate 6, the sealing ring strip 601 matches the position of the sealing strip 7, the sealing strip 7 is composed of rubber 701, and a sealing strip is opened between the rubbers 701 The sealing strip opening groove 702, the sealing ring strip 601 matches the sealing strip opening groove 702, the sealing ring 2 is provided with a limiting cavity 8, the sealing cover plate 6 is provided with a limiting block 9, the limiting cavity 8 matches the limiting block 9, the limiting cavity 8 includes a cavity 801 and the limiting cavity 8 is provided with a limiting opening groove 802, the limiting opening groove 802 is communicated with the cavity 801, the limiting block 9 is composed of a lower fixed block 901 and an upper fixed block 902, the lower fixed block 901 and the upper fixed block 902 are hinged and a spring 903 is connected between the lower fixed block 901 and the upper fixed block 902, the upper fixed block 902 is connected with a clamping block 904, and the clamping block 904 matches the limiting opening groove 802.

[0020] For example:

[0021] When the sealing cover plate 6 is sealing, the sealing ring strip 601 is inserted into the sealing strip opening groove 702 between the rubber 701. At this time, due to the characteristics of the rubber itself, the sealing ring strip 601 will be tightened, thereby achieving a sealing effect;

[0022] When the sealing cover plate 6 needs to be removed, by pressing the clamping block 904, the upper fixing block 902 compresses the spring 903, so that the clamping block 904 can be pushed out from the limiting opening groove 802, and then the sealing ring strip 601 is also pushed out from the sealing strip opening groove 702, thereby realizing the removal of the sealing cover plate 6.
