Problems solved by technology
The way of screw and nut is used for transmission. Although the transmission precision is high, the cost is correspondingly high, and it is very inconvenient to disassemble. Moreover, the movement of the movable bed does not require high transmission accuracy. In addition, the power mechanism and the movable bed Other transmission mechanisms (such as the transmission mechanism that moves the belt on the movable bed) are independent and have no connection with each other. Multiple power transmission mechanisms are set independently, which also leads to complex structure and high cost of this product.

The invention provides a power mechanism for a patient transfer bed. The power mechanism is characterized by comprising a movable beam, a gearbox fixedly arranged on the movable beam and equipped witha motor, a transmission shaft connected with and arranged at the power output end of the gearbox, gear boxes fixedly arranged at two ends of the movable beam and respectively equipped with a gear, and racks arranged at two ends of a bed frame, wherein the gears are rotatably connected with and arranged in the gear boxes; the transmission shaft drives the gears in the gear boxes to rotate; gears,located at two ends of the transmission shaft and driven by the transmission shaft, in the gear boxes are meshed with the racks located at two ends of the bed frame respectively; the movable bed witha conveying belt is fixedly connected with at least one of the movable beam and the gear boxes; and a transmission gear on a clutch arranged on a rolling shaft driving the conveying belt to move is meshed with a gear on a gear box. Compared with the prior art, the power mechanism provided by the invention has the advantages of simple structure, low manufacturing cost and convenience in disassembling and assembling.
Description
technical field [0001] The invention relates to a medical device. Background technique [0002] As disclosed in the patent application CN201911062014.5, the power mechanism of the mobile bed used to transfer the medical patient transfer bed includes a motor arranged on the bed frame, and the motor passes through the transmission mechanism (drive wheel / belt type transmission mechanism or sprocket wheel / chain type transmission mechanism) Mechanism) driven to rotate the threaded rod arranged on the bed frame, the nut screwed on the threaded rod, and the nut is connected with the movable bed frame. The way of screw and nut is used for transmission. Although the transmission precision is high, the cost is correspondingly high, and it is very inconvenient to disassemble. Moreover, the movement of the movable bed does not require high transmission accuracy. In addition, the power mechanism and the movable bed Other transmission mechanisms (such as the transmission mechanism that m...
