[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 7 shown, the present invention provides a highly sealed bearing seat, which includes a lower bearing seat 1 and an upper bearing seat 2. Two opposite sealing baffles 7 are slidably arranged on the front and back surfaces of the lower bearing seat 1, and each sealing baffle 7 is sleeved on the surface of the upper bearing seat 2 and is in contact with the sealing ring on the sealed bearing. The two groups of sealing baffles 7 can not only protect the bearing sealing ring, but also position and fix the upper bearing seat 2, effectively preventing it from loosening, and there is no need to use bolt assemblies, so there is no need to use other tools. A displacement mechanism for adjusting the movement of each sealing baffle 7 is arranged inside the lower bearing seat 1. Through the displacement mechanism, the movement of the left and right groups of sealing baffles 7 can be adjusted, and the mutual approach of the left and right groups of sealing baffles 7 can fix the upper bearing seat 2 on the lower bearing seat 1. Positioning mechanisms are arranged at both ends of the upper bearing seat 2.

[0029] The positioning mechanism includes an installation cavity 68 opened in the upper bearing seat 2 and insertion holes 63 opened in the inner walls of the front and rear sealing baffles 7. The surface of the upper bearing seat 2 is rotatably connected with a second turning handle 61 penetrating into the installation cavity 68. One end of the second turning handle 61 protrudes from the side of the sealing baffle 7, making the protruding part of the second turning handle 61 convenient for personnel to rotate, avoiding inconvenience in use due to the small distance between the two sealing baffles 7, thus making the operation easier. Inside the installation cavity 68, there is a second double-headed screw 67 rotatably connected. A transmission component is arranged between the second turning handle 61 and the second double-headed screw 67. The transmission component includes a second bevel gear 66 fixed in the middle of the second double-headed screw 67. One end of the second turning handle 61 is fixed with a first bevel gear 64 meshing with the second bevel gear 66. The surface of the second double-headed screw 67 is threadedly sleeved with two opposite positioning cylinders 62, and both positioning cylinders 62 are slidably arranged in the installation cavity 68. One end of each of the two positioning cylinders 62 penetrates through the upper bearing seat 2 and is inserted into the insertion hole 63. With the above structure set, when the upper bearing seat 2 is positioned and fixed by the left and right groups of sealing baffles 7, the second turning handle 61 can be rotated to control the rotation of the second double-headed screw 67, further inserting the two positioning cylinders 62 into the corresponding insertion holes 63 respectively, enabling the upper bearing seat 2 to be limited between the two sealing baffles 7. This not only strengthens the stability between the upper bearing seat 2 and the lower bearing seat 1 but also can prevent the sealing baffle 7 from shifting and loosening, ensuring the quick fixation of the upper bearing seat 2 without using bolt components. When it is necessary to disassemble the upper bearing seat 2 to replace the bearing, only need to reverse the second turning handle 61 to control the two positioning cylinders 62 to retract into the installation cavity 68, then control the displacement mechanism to drive the left and right groups of sealing baffles 7 away from the upper bearing seat 2, and finally directly remove the upper bearing seat 2.

[0030] As Figure 4 , Figure 5 shown, both bottom ends of the upper bearing seat 2 are fixedly connected with positioning shafts 11. On both sides of the top end of the lower bearing seat 1, positioning grooves 10 adapted to the positioning shafts 11 are opened, and the positioning shafts 11 are inserted into the positioning grooves 10. With the setting of the positioning grooves 10 and the positioning shafts 11, it is convenient for personnel to quickly position the upper bearing seat 2 on the lower bearing seat 1, facilitating subsequent quick fixation and also preventing offset between the lower bearing seat 1 and the upper bearing seat 2.

[0031] As Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, several anti-slip strips are fixedly connected to the inner rings of both the lower bearing seat 1 and the upper bearing seat 2, which can improve the stability of the bearing between the lower bearing seat 1 and the upper bearing seat 2.

[0032] As Figure 1 , Figure 2 , Figure 5As shown, a number of reinforcing rods 8 are fixedly connected between every two adjacent sealing baffles 7. With the arrangement of the reinforcing rods 8, the stability between every two adjacent sealing baffles 7 is enhanced, thereby ensuring the overall stability of the lower bearing seat 1 and preventing the sealing baffles 7 from deforming.

[0033] As Figure 1 , Figure 2 shown, the displacement mechanism includes a first bidirectional screw rod 4 rotatably connected inside the lower bearing seat 1 and sliding grooves 5 formed on the front and back surfaces of the lower bearing seat 1. One end of the first bidirectional screw rod 4 penetrates through the lower bearing seat 1 and is fixedly connected with a first rotating handle 3. Two opposite moving plates 9 are threadedly sleeved on the surface of the first bidirectional screw rod 4. Both moving plates 9 penetrate through the sliding grooves 5 and are respectively connected with the left and right sealing baffles 7. Both ends of the two moving plates 9 slide in the two sliding grooves 5. With the above structure, by rotating the first rotating handle 3 by a person, the two moving plates 9 can be driven to move relatively inside the lower bearing seat 1, further driving the relative movement of the left and right groups of sealing baffles 7. After the upper bearing seat 2 is placed on the lower bearing seat 1, the left and right groups of sealing baffles 7 can squeeze and fix the upper bearing seat 2, ensuring the stability of the upper bearing seat 2 on the lower bearing seat 1. There is no need to use bolt assemblies to fix the upper bearing seat 2 on the lower bearing seat 1. By using the displacement mechanism and the positioning mechanism in cooperation, the stability of the upper bearing seat 2 can be ensured, preventing it from loosening, and no other tools are required during the maintenance of the bearing.

[0034] As Figure 7 shown, a vertical plate 65 is fixedly connected to the inner wall of the installation cavity 68, and the second bidirectional screw rod 67 is rotatably connected inside the vertical plate 65. The vertical plate 65 is arranged in the middle of the second bidirectional screw rod 67. With the arrangement of the vertical plate 65, it not only provides support stability for the second bidirectional screw rod 67 but also ensures the rotational stability of the second bidirectional screw rod 67, and the first bevel gear 64 does not contact the vertical plate 65.

[0035] Working principle and usage process of the present invention: First, place the bearing on the lower bearing seat 1, then position the upper bearing seat 2 on the lower bearing seat 1, and rotate the first turning handle 3 to drive the two moving plates 9 to move relative to each other within the lower bearing seat 1, further driving the left and right groups of sealing baffles 7 to squeeze and fix the upper bearing seat 2, ensuring the stability of the upper bearing seat 2 on the lower bearing seat 1 without using bolt components to fix the upper bearing seat 2 on the lower bearing seat 1. After the upper bearing seat 2 is positioned and fixed by the left and right groups of sealing baffles 7, rotate the second turning handle 61 to control the rotation of the second bidirectional screw 67, further inserting the two positioning cylinders 62 into the corresponding jacks 63 respectively, enabling the upper bearing seat 2 to be limited between the two sealing baffles 7. This not only strengthens the stability between the upper bearing seat 2 and the lower bearing seat 1 but also prevents the sealing baffles 7 from shifting and loosening, ensuring the quick fixation of the upper bearing seat 2 without using bolt components. When it is necessary to disassemble the upper bearing seat 2 to replace the bearing, just reverse-rotate the second turning handle 61 to control the two positioning cylinders 62 to retract into the installation cavity 68, then control the displacement mechanism to drive the left and right groups of sealing baffles 7 away from the upper bearing seat 2, and finally directly remove the upper bearing seat 2, making the replacement of the bearing more convenient and reducing the maintenance time.
