Specific implementation manners
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0024] Embodiment 1
[0025] Please refer to Figures 1-3 As shown, a fan bearing seat structure includes a bottom plate 1;
[0026] A lower base 3 is fixedly connected to the center of the top of the bottom plate 1. An upper base 7 is arranged on the top of the lower base 3. A connecting component 5 is arranged between the upper base 7 and the lower base 3. Arc-shaped mounting grooves 4 are formed on the opposite sides of the upper base 7 and the lower base 3. An inner groove 9 is formed inside the upper base 7. Through oil injection holes 6 are formed on the upper and lower surfaces inside the inner groove 9. A sealing component 8 is arranged inside the inner groove 9. During operation, first, the bottom of the bottom plate 1 is fitted to a flat ground to make the bearing seat stable. After placement, the bearing, rotating shaft, etc. to be installed on the bearing seat are installed between the mounting grooves 4 of the upper base 7 and the lower base 3. Then, the connecting component 5 makes the connection between the upper base 7 and the lower base 3 firm. After the installation is firm, the sealing component 8 seals the oil injection holes 6, and the oil injection holes 6 can also be opened for oil injection through the sealing component 8 during oil injection. Therefore, the sealing component 8 seals and opens the oil injection holes 6, and has a good sealing effect, thus facilitating the opening and sealing of the oil injection holes 6, with convenient operation and no need to worry about subsequent sealing effects, making the bearing seat convenient to use and highly practical.
[0027] Upper and lower through-mounted mounting holes 2 are formed on the left and right sides inside the bottom plate 1. During operation, the mounting holes 2 facilitate the penetration of mounting bolts through the bottom plate 1 for fixed installation with an external mounting surface.
[0028] The two mounting grooves 4 communicate with each other internally, and the upper mounting groove 4 communicates with the oil injection hole 6 internally. During operation, it is convenient for the injected lubricating oil to enter the mounting groove 4 through the oil injection hole 6, enabling the bearing installed inside the bearing seat to be lubricated during rotation.
[0029] The connecting component 5 includes through holes two 503 formed on the left and right sides inside the lower base 3 and penetrating up and down. Through holes one 502 penetrating up and down are formed on the left and right sides inside the upper base 7. A connecting bolt 501 penetrates through the through hole one 502 and the through hole two 503. A nut 504 is threadedly connected to the lower surface of the outer surface of the connecting bolt 501. During operation, the nut 504 is threadedly connected to the connecting bolt 501 penetrating through the through hole one 502 and the through hole two 503 to make the connection between the upper base 7 and the lower base 3 firm, and make the bearing installed inside the bearing seat firmly installed.
[0030] The sealing assembly 8 includes sliders 803 slidably connected to the left and right sides inside the inner groove 9. A guiding hole 804 is formed in the lower part inside the slider 803. An oil injection pipe 805 is fixedly connected to the lower surface inside the inner groove 9. Guide rods 801 are fixedly connected to both the left and right sides between the outer surface of the oil injection pipe 805 and the inside of the inner groove 9. A spring 802 is fixedly connected between the slider 803 and the inner groove 9. The end of the guide rod 801 penetrates through the guiding hole 804 and the spring 802. A sealing plate 806 is fixedly connected to the side of the slider 803. An arc-shaped extrusion section 807 and a planar sealing section 808 are sequentially formed on the side of the sealing plate 806 from top to bottom. During operation, the oil injection pipe 805 and the oil injection hole 6 are sealed by the fitting of the two sealing plates 806. When oil needs to be injected, an external injection pipe is inserted into the oil injection hole 6. Then, the external injection pipe extrudes the extrusion end of the sealing plate 806, and the arc-shaped extrusion section 807 is easily extruded open. Immediately after the sealing plate 806 is extruded, it moves under the limitation of the sliding of the slider 803 inside the inner groove 9. When the slider 803 slides, it slides under the limitation of the sliding connection between the guide rod 801 and the guiding hole 804, making the movement of the sealing plate 806 and the slider 803 stable. Then, since the movement of the slider 803 squeezes the spring 802, the spring 802 has a rebounding force. When the external injection pipe is withdrawn after the oil injection is completed, the extrusion on the sealing plate 806 is removed, and under the action of the rebounding force of the spring 802, the two sealing plates 806 move to fit again to seal the oil injection pipe 805 and the oil injection hole 6, thus facilitating the opening and sealing of the oil injection hole 6, with convenient operation and no need to worry about the subsequent sealing effect, making the bearing seat easy to use and highly practical.
[0031] The bottom of the sealing plate 806 is in contact with the top of the oil injection pipe 805, and the opposite sides of the two sealing sections 808 are in contact with each other. During operation, it is convenient to inject oil through the oil injection pipe 805 after the sealing plate 806 is opened, and the contact of the sealing sections 808 seals the oil injection pipe 805 and the oil injection hole 6.

[0033] Please refer to Figure 4 As shown in the figure, compared with Embodiment 1, as another implementation manner of the present invention, handle grooves 10 are formed on both the left and right sides of the upper base 7. During operation, the handle grooves 10 facilitate the movement and handling of the bearing seat.
