Description
Technical Field
The present invention relates to a medical device.
Background
As disclosed in the patent application CN201911062014.5, the power mechanism of the movable bed for transferring medical patients comprises a motor disposed on the bed frame, a lead screw rotatably disposed on the bed frame and driven by the motor through a transmission mechanism (a transmission wheel/transmission belt type transmission mechanism or a chain wheel/chain type transmission mechanism), and a nut screwed on the lead screw, wherein the nut is connected with the movable bed frame. The transmission is realized by adopting the screw rod and the nut, although the transmission precision is high, the cost is correspondingly high, the disassembly and the assembly are inconvenient, in addition, the movement of the movable bed does not need high transmission precision, in addition, the power mechanism and other transmission mechanisms of the movable bed (such as a transmission mechanism for moving a belt on the movable bed) are independent and are not connected with each other, and various power transmission mechanisms are independently arranged, so that the structure of the product is complicated and the cost is high.
Disclosure of Invention
The invention aims to provide a power mechanism for transferring a movable bed for a medical patient transfer bed, which has low manufacturing cost and convenient assembly and disassembly.
The invention is realized by the following steps that the bed comprises a motor arranged on a bed frame, a transmission optical axis driven by the motor through a transmission mechanism, a gearbox, transmission shafts on two sides of the gearbox, a gear connected to the end part of the transmission shaft and racks arranged on two sides of the bed frame, wherein the transmission optical axis is movably connected in a power input shaft hole of the transmission optical axis of the gearbox in the front and back directions, the two transmission shafts are respectively connected to power output ends on two sides of the gearbox, and the gearbox is connected below a movable bed frame of the movable.
When the transmission mechanism works, the motor rotates through a transmission optical axis driven by the transmission mechanism, the transmission optical axis drives a driving helical gear in the gearbox to rotate, the driving helical gear drives a driven helical gear in the gearbox to rotate, the driven helical gear drives the transmission shaft to rotate, so that the longitudinal rotation of the transmission optical axis is converted into the transverse rotation of the transmission shaft, the transmission shaft drives gears on two sides to synchronously rotate, the rotating gears roll back and forth along the racks, the gearbox is driven to move back and forth along the transmission optical axis, and the movable bed which is fixedly connected with the transmission mechanism is driven to move back and forth. Because the gearbox, the transmission optical axis and the transmission shaft (the transmission shafts on two sides of the gearbox can adopt a shaft which transversely penetrates through the gearbox) can be connected to the gearbox in a cross-connecting mode, and the gear is only placed on the rack to complete assembly, the assembly is convenient to disassemble and assemble, and the gearbox, the gear and the rack are adopted for transmission, so that the cost is low compared with the transmission technology of a screw rod and a nut, moreover, the rack and the gear can be shared with the rack and the gear of a roller which is used for driving a transmission belt on a movable bed to move on the movable bed, and therefore, the whole structure of the movable bed can be effectively simple.
Compared with the prior art, the invention has the advantages of simple structure, low manufacturing cost and convenient disassembly and assembly.
