[0005] In order to achieve the above object, the utility model adopts the following technical scheme: a waist bridge lifting device for operating table, which comprises a bed frame, a driving rod, a first driving gear, a first driven gear, a second driving gear, a second driven gear, a sleeve, a first lead screw, a second lead screw and a waist bridge bracket, the driving rod is hinged on the bed frame, the first driving gear is installed on the driving rod, the first driven gear and the second driving gear are installed on the bed frame through a bearing seat, the sleeve is installed on the bed frame, the first lead screw is inserted into the sleeve, the second lead screw is inserted into the first lead screw and is internally screwed with the first lead screw, the waist bridge bracket is fixedly connected to the end of the second lead screw, the second driven gear is sleeved on the sleeve, the inner wall of the second driven gear is screwed with the first lead screw, the first driving gear is engaged with the first driven gear, and the second driving gear is engaged with the second driven gear.

[0006] Further description of the above technical scheme:

[0007] The first driving gear and the first driven gear are both spiral bevel gears.

[0008] Further description of the above technical scheme:

[0009] The second driving gear and the second driven gear are both spur gears.

[0010] Further description of the above technical scheme:

[0011] The second driven gear is connected with the sleeve through a rotary table bearing.

[0012] As described above, due to the adoption of the above technical scheme, the utility model has the beneficial effects that:

[0013] In the utility model, the first driving gear is driven to rotate by rotating the driving rod, and the first driving gear drives the first driven gear and the second driving gear to rotate synchronously along the bearing seat. The second driving gear rotates to drive the second driven gear to rotate. The screw connection between the second driven gear and the first screw rod enables the first screw rod to rise and fall in the sleeve, thereby driving the waist bridge bracket on the second screw rod to rise and fall. The second screw rod can also be actively rotated to be screwed and rotated in the first screw rod, thereby adjusting the lifting and lowering of the waist bridge bracket, making the lifting and lowering operation of the waist bridge bracket simple and convenient, and highly flexible to use.
