The fixing seat 4 is fixed on the foundation 10, and the upper end of the fixing seat 4 extends upward after passing through the mounting hole 11 of the bed body 1. The lower support sleeve 5 is slidably sleeved on the light rod 42 of the fixing seat 4. The upper support sleeve 6 is slidably sleeved on the light rod 42 and the screw rod 43 of the fixing seat 4, and the upper support sleeve 6 is slidably matched with the mounting hole 11. The screw rod 43 is integrally connected to the upper end of the light rod 42, and the screw rod 43 extends upward after passing through the mounting hole 11. The locking assembly is in abutment with the upper support sleeve 6. The rubber ring 2 is sleeved on the light rod 42 and is in abutment and connection between the upper support sleeve 6 and the lower support sleeve 5. The locking assembly is threadedly installed on the screw rod 43. When the locking assembly is locked on the screw rod 43, the relative movement between the upper support sleeve 6 and the lower support sleeve 5 is enabled, and the rubber ring 2 is deformed by being squeezed, so that the rubber ring 2 is in close abutment with the inner wall of the mounting hole 11 and the light rod 42, thereby reliably connecting the bed body 1 and the light rod 42, and the fixing seat 4 is fixed on the foundation 10, so that the bed body 1 is stably fixed on the foundation 10 through the base.

[0035] As Figure 6 shown, the upper end of the rubber ring 2 has an upper protruding portion 23, the lower end of the rubber ring 2 has a lower protruding portion 28, the outer end of the rubber ring 2 has an outer protruding portion 21, and the inner end of the rubber ring 2 has an inner protruding portion 26.

[0037] Preferably, the second inclined surface 24 abuts against the lower inclined surface 62, so that the rubber ring 2 is more closely fitted with the upper supporting sleeve 6, thereby increasing the tightness of the connection among the lower supporting sleeve 5, the rubber ring 2 and the upper supporting sleeve 6.

[0038] As shown in Figure 2 The fixing base 4 further comprises a base 41 mounted on the foundation bolt 3 of the foundation 10, and a light rod 42 connected between the base 41 and a screw rod 43, which is mounted on the foundation bolt 3 through the base 41, so as to improve the connection strength between the fixing base 4 as a whole and the foundation 10.

[0039] As shown in Figure 5 The lower supporting sleeve 5 comprises a lower supporting part 51 and an upper supporting part 52 connected integrally, both of which are slidingly sleeved on the light rod 42, the upper supporting part 52 is slidingly fitted with the mounting hole 11, and the connection between the lower supporting part 51 and the upper supporting part 52 has a shoulder surface 53 abutting against the bottom surface of the bed body 1, so as to limit the lower end of the bed body 1, while the lower supporting part 51 is supported on the base 41, thereby increasing the positional fixing effect among the bed body 1, the lower supporting sleeve 5 and the base 41, so as to facilitate accurate installation. In addition, the lower protruding part 28 abuts against the upper end surface 54, i.e. the bottom of the rubber ring 2 always abuts against the lower supporting sleeve 5.

[0040] As shown in Figure 4 The upper supporting sleeve 6 comprises a body 61 and a flange 63 connected integrally, the flange 63 has a gap with the top surface of the mounting hole 11, the lower end of the body 61 is slidingly fitted with the light rod 42, the upper end of the body 61 is gap-fitted with the screw rod 43, the lower inclined surface 62 is arranged at the lower end of the body 61, and the top of the rubber ring 2 always abuts against the upper supporting sleeve 6.

[0041] As shown in Figure 1 and Figure 3 The locking assembly comprises a hexagonal nut 7, a spring washer 8 and a hexagonal locking nut 9, both of which are threadedly connected with the screw rod 43, the hexagonal nut 7 can abut against the flange 63, the spring washer 8 is sleeved on the screw rod 43 and can abut against the hexagonal nut 7, so as to make the connection between the hexagonal nut 7 and the hexagonal locking nut 9 more reliable, and the hexagonal locking nut 9 is threadedly connected with the screw rod 43 and abuts against the spring washer 8.

[0042] Working principle: when installing, first install the base 41 with the anchor bolt 3, then install the fixed seat 4 in the installation hole 11, then sequentially install the lower support sleeve 5, the rubber ring 2 and the upper support sleeve 6 on the fixed seat 4, then sequentially install the hexagonal nut 7, the spring washer 8 and the hexagonal locking nut 9 on the screw rod 43, rotate and tighten the hexagonal nut 7, the hexagonal nut 7 will extrude the upper support sleeve 6, so that the upper support sleeve 6 slides downward along the polished rod 42, so that the upper support sleeve 6 extrudes the rubber ring 2, the rubber ring 2 presses the lower support sleeve 5, under the action of the rotation and tightening of the hexagonal nut 7, the upper support sleeve 6 and the lower support sleeve 5 extrude the rubber ring 2 to be extruded and deformed, the outer protruding part 21 of the rubber ring 2 tightly abuts against the inner wall of the installation hole 11, the inner protruding part 26 of the rubber ring 2 tightly abuts against the polished rod 42, finally rotate the hexagonal locking nut 9, so that the hexagonal locking nut 9 extrudes the spring washer 8 to lock the hexagonal nut 7, so that the bed body 1 is connected more closely with the polished rod 42, so that the bed body 1 is fixed, stable and reliable.

[0043] In summary, the application is not only easy to install, but also stable and reliable in connection, so that the bed body 1 can be firmly fixed on the foundation 10.
