It can be understood that the foregoing solution can be used in scenarios to prevent the fixing bolt from loosening, and can also prevent the fixing component from interfering with the staff when the bolt is screwed.

[0021] For this specific embodiment, the bearing 101 is installed above the base 100. Both the base 100 and the bearing 101 are the base and bearing described in the existing patent technology CN210859580U, a new type of bearing seat for a washing machine. The bearing 101 is installed above the base 100, so that the motor is driven through the bearing seat. Through this solution, when the motor vibrates, the fastening bolt will not rotate, thus ensuring the stability of the connection between the bearing seat and the motor and ensuring the working performance of the bearing 101.

[0022] Among them, the mounting seat 102 is fixedly connected to the base 100 and is located on one side of the base 100 close to the bearing 101.

Through the mounting seat 102, the fixing box 103 is firmly installed on the base 100. The fixing block 104 has a concave hole for cooperating with the fastening bolt. The fixing block 104 is installed on the fixing box 103 through the driving member. The driving member drives the fixing block 104 to abut against the bolt head connecting the abutment and the motor, thereby preventing the fastening bolt from rotating during use, and further realizing that when the motor vibrates, the fastening bolt will not rotate, thus ensuring the stability of the connection between the bearing seat and the motor and ensuring the working performance of the bearing 101.

[0023] Secondly, the moving block 105 is slidably connected to the fixed box 103 and is located inside the fixed box 103, and a part thereof extends out of the fixed box 103 to be connected to the fixed block 104; the abutting block 106 is fixedly connected to the moving block 105 and is located on the side of the moving block 105 away from the fixed block 104; the elastic element is installed on the fixed box 103, the elastic element drives the abutting block 106 to move, the moving block 105 is slidably installed on the fixed box 103, the fixed box 103 has a chute cooperating with the moving block 105, and a part of the moving block 105 extends out of the outside of the fixed box 103 to be connected to the fixed block 104, so that the moving block 105 drives the fixed block 104 to move. The abutting block 106 is installed on the side of the moving block 105 away from the fixed block 104 through a bolt. By moving the abutting block 106, the moving block 105 is moved, and at the same time, the movement of the moving block 105 is restricted by the abutting block 106 to prevent the moving block 105 from sliding out of the fixed box 103. The elastic member is installed inside the fixed box 103. The elastic member drives the abutting block 106 to move, so that the abutting block 106 drives the moving block 105 to move, and further the fixed block 104 abuts against the fastening bolt.

[0024] Meanwhile, the telescopic rod 107 is fixedly connected to the fixed box 103 and is located inside the fixed box 103, and is connected to the abutting block 106; the spring 108 is sleeved outside the telescopic rod 107, and two ends of the spring 108 respectively abut against the abutting block 106 and the fixed box 103; the retracting part is installed on the abutting block 106, the retracting part drives the abutting block 106 to move, one end of the telescopic rod 107 is installed on the fixed box 103 through a bolt, the other end of the telescopic rod 107 is installed on the abutting block 106 through a bolt, the spring 108 is sleeved outside the telescopic rod 107, and two ends of the spring 108 respectively abut against the abutting block 106 and the fixed box 103, so that the spring 108 can push the abutting block 106 to move. The retracting part is installed on the abutting block 106, and the abutting block 106 is moved by the retracting part to overcome the elastic force of the spring 108.

[0025] In addition, the protruding rod 109 is fixedly connected to the abutting block 106, is located on one side of the abutting block 106 close to the telescopic rod 107, and partially protrudes from the fixed box 103; the pushing block 110 is fixedly connected to the protruding rod 109 and is located on one side of the protruding rod 109 away from the abutting block 106. One end of the protruding rod 109 is fixed to one end of the abutting block 106 close to the protruding rod 109. The abutting block 106 is driven to move through the protruding rod 109. The pushing block 110 is installed on one side of the protruding rod 109 away from the abutting block 106, and the protruding rod 109 is pushed more labor - saving through the pushing block 110.

[0026] When using the rust - proof and high - strength washing machine bearing seat casting of this embodiment, when installing the base 100 on the motor, by pushing the pushing block 110, the protruding rod 109 drives the abutting block 106 to move inwards, so that the fixing block 104 moves away from the hole reserved on the base 100, which is convenient for the staff to screw on the fastening bolt. When the fixing is completed, the pushing block 110 is released, so that the spring 108 pushes the abutting block 106, and the abutting block 106 drives one side of the fastening bolt on the fixing block 104 through the moving block 105, and the fixing block 104 is engaged with the fastening bolt, so that when the motor vibrates, the fastening bolt will not rotate, thus ensuring the stability of the connection between the bearing seat and the motor and guaranteeing the working performance of the bearing 101.

[0027] The second embodiment of this application is as follows:

[0028] On the basis of the first embodiment, please refer to Figure 3 , Figure 3 which is the installation schematic diagram of the fixed seat and the plug pin of the second embodiment of the present utility model.

[0029] The fixed component of this embodiment further includes a fixed seat 211 and a plug pin 212.

[0030] Among them, the fixed seat 211 is fixedly connected to the fixed box 103 and is located on one side of the fixed box 103 close to the extending rod 109; the bolt 212 is slidably connected to the fixed seat 211 and is located on one side of the fixed seat 211 close to the extending rod 109; and it abuts against the extending rod 109. The fixed seat 211 is installed on one side of the fixed box 103 close to the extending rod 109 by welding; the bolt 212 is slidably installed on the fixed seat 211. The width of the bolt 212 is the length that the extending rod 109 can move. Thus, when the fixed seat 211 is engaged with the fastening bolt, the bolt 212 abuts against the rear side of the extending rod 109 to prevent the fixed block 104 from moving backward. When the fixed block 104 is away from the fastening bolt, the bolt 212 abuts against the front side of the extending rod 109 to prevent the fixed block 104 from moving forward.

[0031] When using a rust-proof and high-strength washing machine bearing seat casting of this embodiment, after the fixed block 104 is engaged with the fastening bolt, insert the bolt 212 to make the bolt 212 abut against the rear side of the extending rod 109 to prevent the fixed block 104 from moving backward.
