[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 6 As shown, the utility model provides an antistatic bearing, including an outer ring 1 and an inner ring 3, a top plate of the outer ring 1 is provided with a mounting groove 10, an inner wall of one side of the mounting groove 10 is fixedly connected with a telescopic rod 8, one end of the telescopic rod 8 is fixedly connected with a limiting block 9, an inner surface of the mounting groove 10 is provided with a clamping block 5, an outer surface of the telescopic rod 8 is sleeved with a spring 7, the top of the clamping block 5 is fixedly connected with a grounding wire 4, an outer surface of one side of the limiting block 9 is fixedly connected with a handle 6, the outer surface of the clamping block 5 is slidably arranged with the inner surface of the mounting groove 10, the outer surface of the limiting block 9 is slidably arranged with the inner surface of the mounting groove 10, the outer surface of the limiting block 9 is clamped with the outer surface of the clamping block 5, one end of the spring 7 is fixedly connected with the outer surface of the clamping block 5, and the other end of the spring 7 is fixedly connected with the outer surface of one side of the mounting groove 10.

[0025] The effect achieved by the entire embodiment 1 is that when the bearing is in use, the block 5 is aligned with the installation groove 10 so that the block 5 is in close contact with the right inner wall of the installation groove 10, and then the block 5 is moved downward. Through the downward movement of the block 5, the cross-section of the limit block 9 is subjected to an extrusion force, thereby driving the spring 7 and the telescopic rod 8 to be compressed, so that the limit block 9 moves downward to the left. Therefore, the block 5 is completely inserted into the installation groove 10. At the same time, the limit block 9 is no longer squeezed. Under the restoring force of the spring 7, the limit block 9 is pushed to the right. Under the action of the telescopic rod 8, the moving direction of the limit block 9 is limited, so that under the action of the limit block 9, the block 5 is engaged in the installation groove 10. Figure 6As shown, at the same time, under the action of spring 7, a certain pressure will always be applied to limit block 9, so that block 5 fits tightly with outer ring 1, and then grounding wire 4 contacts with the ground, so that static electricity accumulated on the bearing can be introduced into the ground through grounding wire 4, reducing the impact of static electricity on bearings or electronic components, improving the service life of bearings, and making bearings have better anti-static properties. When it is necessary to disassemble grounding wire 4, it is only necessary to pull handle 6 to the left to move limit block 9 to the left, and then block 5 and grounding wire 4 can be quickly removed for inspection and maintenance to ensure the grounding effect.

[0026] Embodiment 2, as Figure 1-Figure 6 As shown, a plurality of balls 12 are arranged between the outer surfaces of the outer ring 1 and the inner ring 3, a first sealing ring 11 is fixedly connected to the inner surface of the outer ring 1, a second sealing ring 13 is fixedly connected to the outer surface of the inner ring 3, a rubber pad 2 is arranged between the outer surfaces of the outer ring 1 and the inner ring 3, a first sealing groove 15 is provided on the outer surface of the rubber pad 2, a second sealing groove 16 is provided on the inner surface of the rubber pad 2, the first sealing ring 11 and the second sealing ring 13 are respectively matched with the first sealing groove 15 and the second sealing groove 16, and an inclination angle 14 is provided at the bottom of the rubber pad 2.

[0027] The effect achieved by the entire embodiment 2 is that when installing the rubber pad 2, the rubber pad 2 is aligned with the gap between the outer ring 1 and the inner ring 3, and then the rubber pad 2 is pressed downward. The setting of the inclination angle 14 of the rubber pad 2 facilitates the installation of the rubber pad 2, and the first sealing ring 11 and the second sealing ring 13 are respectively inserted into the first sealing groove 15 and the second sealing groove 16 to perform double sealing, thereby preventing dust from entering and adhering to the ball 12, thereby ensuring the sealing of the bearing.

[0028] Working principle: when the bearing is in use, align the block 5 with the installation groove 10 so that the block 5 is in close contact with the right inner wall of the installation groove 10, and then push the block 5 downward. By moving the block 5 downward, the cross section of the limit block 9 is subjected to extrusion force through the setting of the limit block 9, thereby driving the spring 7 and the telescopic rod 8 to be compressed, so that the limit block 9 moves downward and to the left. Therefore, the block 5 is completely inserted into the installation groove 10. At the same time, the limit block 9 is no longer squeezed. Under the restoring force of the spring 7, the limit block 9 is pushed to the right. Under the action of the telescopic rod 8, the moving direction of the limit block 9 is limited, so that the block 5 is engaged in the installation groove 10 under the action of the limit block 9. Figure 6As shown, at the same time, under the action of the spring 7, a certain pressure will always be applied to the limit block 9, so that the block 5 is tightly fitted with the outer ring 1, and then the grounding wire 4 is in contact with the ground, so that the static electricity accumulated on the bearing can be introduced into the ground through the grounding wire 4, reducing the impact of static electricity on the bearing or electronic components, improving the service life of the bearing, and making the bearing have better anti-static properties. When the grounding wire 4 needs to be disassembled, it is only necessary to pull the handle 6 to the left to move the limit block 9 to the left, and the block 5 and the grounding wire 4 can be quickly removed for inspection and maintenance to ensure the grounding effect. At the same time, when the bearing is in use, the first sealing ring 11 and the second sealing ring 13 are respectively inserted into the first sealing groove 15 and the second sealing groove 16 to complete the installation of the rubber pad 2 and ensure the sealing of the bearing.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
