Detailed Description

Referring to a liftable bearing seat shown in fig. 1 to 4, the liftable bearing seat comprises a base 1, the inside and four terminal angles that are close to of base 1 all are provided with mounting hole 2, base 1 top is provided with bottom plate 3, the bottom plate 3 top is provided with top frame 4, be provided with bearing body 5 in the top frame 4, lift lead screw 6 is all installed in rotation of base 1 top four sides, four sides of bottom plate 3 respectively with four lift lead screw 6 threaded connection, base 1 top is provided with driving piece 7, driving piece 7 is connected with lift lead screw 6 transmission.

Further, lifting screw 6 outer wall threaded connection has screwed pipe 8, the inside round hole that is provided with screwed pipe 8 looks adaptation of bottom plate 3, screwed pipe 8 outside is provided with fastener 9, screwed pipe 8 passes through fastener 9 and bottom plate 3 swing joint, fastener 9 includes sleeve plate 91 and mounting bolt 92, sleeve plate 91 is fixed to be cup jointed in screwed pipe 8 outside and is located bottom plate 3 bottom, be provided with mounting bolt 92 on the sleeve plate 91, mounting bolt 92 one end screw thread runs through in bottom plate 3.

Through the setting of screwed pipe 8 to improve the stability of lift lead screw 6 and bottom plate 3 threaded connection, so that lift lead screw 6 rotates and drives bottom plate 3 and carry out vertical removal, and the rotatory mounting bolt 92 makes it break away from bottom plate 3, in order to release the connected state of bottom plate 3 and screwed pipe 3, upwards moves bottom plate 3 and makes its inside round hole break away from screwed pipe 3 (not shown in the round hole diagram), thereby can accomplish the separation process of bottom plate 3 and screwed pipe 3, so that take off the structure at bottom plate 3 and top alone.
