[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 Figure 1-4 The utility model provides a technical solution: a bearing seat with a dustproof mechanism, including a bearing seat 1, a mounting bracket 2 is fixedly connected to the top of the bearing seat 1, a symmetrically arranged support rod 3 is rotatably connected to the mounting bracket 2, both ends of the two support rods 3 are fixedly connected to a connecting block 4, the bottom ends of multiple connecting blocks 4 are fixedly connected to a blocking ring 5, the middle positions of the two support rods 3 are fixedly connected to a toggle block 6, the tops of the two toggle blocks 6 are fixedly connected to a pressure block 7, a screw rod 8 is rotatably connected to the center position of the mounting bracket 2, a symmetrically arranged guide rod 9 is fixedly connected to the middle position of the mounting bracket 2, and the two guide rods 9 are slidably connected to an extrusion plate 10.

[0018] The mounting frame 2 is located in the middle position of the top end of the bearing seat 1. The specific shape of the mounting frame 2 is a C-shaped setting. The mounting frame 2 is convenient for providing support for the rotation of the support rod 3. The blocking rings 5 are all semicircular settings. The fitting parts of adjacent blocking rings 5 are provided with a rubber layer. The rubber layer on the blocking ring 5 can make each blocking ring 5 fit more tightly. The pressure blocks 7 are fixedly connected to the toggle block 6 at the internal position of the mounting frame 2. The pressure blocks 7 are all triangular settings. The triangular pressure blocks 7 are convenient for being squeezed by the extrusion plate 10. The top end of the screw rod 8 is fixedly connected with a rotating ring 11. The screw rod 8 is threadedly connected to the center position of the extrusion plate 10. The rotating ring 11 is convenient for driving the screw rod 8 to rotate. When the screw rod 8 rotates, it is convenient for driving the extrusion plate 10 to move up and down.

[0019] Specifically, when using the present invention, when it is necessary to fit adjacent blocking rings 5 together, first directly rotate the toggle block 6 to the side away from each other, the toggle block 6 will drive the support rod 3 to rotate, the support rod 3 will drive the connecting block 4 to rotate downward, the connection block 4 will drive the blocking ring 5 to rotate, and each blocking ring 5 will rotate toward the middle position below and slowly fit together. At this time, the rotation of the toggle block 6 and the support rod 3 can be stopped, and the screw rod 8 can be rotated by the rotating ring 11. The screw rod 8 will drive the extrusion plate 10 to move downward, and the two guide rods 9 are the extrusion plates 10. When the screw rod 8 is stopped, the tightly connected blocking ring 5 provides a barrier for the connection between the shaft and the bearing to prevent the invasion of dust.
