DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7 This utility model provides a technical solution: an adjustable bearing seat, including a base 1, four support columns 2 fixedly connected to the upper end of the base 1, two symmetrical sliding columns 3 fixedly connected to the upper end of the base 1, lower bearing sleeves 4 fixedly connected to the side walls of the four support columns 2, upper bearing sleeves 5 slidably connected to the side walls of the four support columns 2, limit plates 6 fixedly connected to both sides of the inner walls of the lower bearing sleeves 4 and the upper bearing sleeves 5, the same bearing 7 being engaged on the inner walls of the lower bearing sleeves 4 and the upper bearing sleeves 5, lifting blocks 9 fixedly connected to both sides of the upper bearing sleeves 5, and a... The same top plate 10 has a fixed plate 11 fixedly connected to its upper end. The fixed plate 11 has two movable holes 12 on its side. A rotating hole 19 is provided at the center of the upper surface of the top plate 10. A moving rod 21 is fixedly connected to the rotating hole 19. An L-shaped block 20 is rotatably connected to the surface of the moving rod 21. A clamping groove 22 is provided on the surface of the L-shaped block 20. Four support columns 2 fix the lower bearing sleeve 4 and the upper bearing sleeve 5 so that the lower bearing sleeve 4 and the upper bearing sleeve 5 cannot move left or right. The L-shaped block 20 is rotated through the rotating hole 19 and the moving rod 21 so that the lifting block 9 can move the upper bearing sleeve 5 up and down.

[0021] Furthermore, two through holes 8 are symmetrically opened on the upper surfaces of the lower bearing sleeve 4 and the upper bearing sleeve 5, and two sliding pillars 3 are inserted into the four through holes 8, so that the upper bearing sleeve 5 and the lower bearing sleeve 4 can only move up and down.

[0022] Furthermore, two square blocks 13 are fixedly connected to the upper end of the top plate 10. Each square block 13 has a circular groove 14. A return spring 15 is fixedly connected to the inner sidewall of each square block 13. A limit post 16 is fixedly connected to the other end of each return spring 15. The other end of each limit post 16 is fixedly connected to the same U-shaped plate 17. Both ends of the U-shaped plate 17 are inserted into two movable holes 12. Pull blocks 18 are fixedly connected to both sides of the U-shaped plate 17. Pulling the pull blocks 18 moves the U-shaped plate 17. When the U-shaped plate 17 is not in contact with the L-shaped block 20, the L-shaped block 20 can rotate, compressing the two limit posts 16 fixedly connected to the U-shaped plate 17 and compressing the return springs 15. When the pull blocks 18 are not pulled, the return springs 15 spring back the limit posts 16.

[0023] Furthermore, all four limiting plates 6 are fitted to the bearing 7, which can fix the bearing 7 in place and prevent it from loosening.

[0024] Furthermore, the U-shaped plate 17 is inserted into the clamping groove 22 at its center. When the U-shaped plate 17 is not moved, it can lock the clamping groove 22, making the L-shaped block 20 unable to move and thus more secure.

[0025] Specifically, in use, the pull block 18 is first pulled, which moves the U-shaped plate 17 fixedly connected to the pull block 18, and moves the two limiting posts 16 fixedly connected to the U-shaped plate 17, causing the limiting posts 16 to compress the return spring 15. When the U-shaped plate 17 moves to a point where it no longer contacts the L-shaped block 20, it pushes laterally at the lower end of the L-shaped block 20. At this time, the L-shaped block 20 rotates on the rotating hole 19 via the moving rod 21. When it rotates to a certain extent, the L-shaped block 20 can no longer rotate. By pulling the lifting block 9 upward, the upper bearing sleeve 5 moves upward on the sliding post 3, increasing the distance between the upper bearing sleeve 5 and the lower bearing sleeve 4, making installation or disassembly easier. When the bearing 7 is removed, and the installation or disassembly is completed, lower the upper bearing sleeve 5. When the upper bearing sleeve 5 and the lower bearing sleeve 4 are in contact, push the L-shaped block 20 back and release the pull block 18. The return spring 15 has no tension and generates a rebound force, which drives the U-shaped plate 17 connected to the pull block 18 to push forward until the middle of the U-shaped plate 17 jams the L-shaped block 20. Both ends of the U-shaped plate 17 are inserted into the movable holes 12, so that the U-shaped plate 17 is fixed to the top plate. The lower end of the L-shaped block 20 is close to the upper end of the upper bearing sleeve 5, so that the upper bearing sleeve 5 and the lower bearing sleeve 4 can be fixed during long-term operation, avoiding damage to the bearing sleeve and bearing 7 when the bearing sleeve is loose.
