Abstract

The invention relates to a liftable medical nursing bed capable of using a motor to control automatic lifting of the bed surface, which comprises a pedestal and a bed frame, wherein a hinge lug connected with the lower parts of a front middle cross beam and a rear middle cross beam is hinged with two ends of an upper end shaft of an n-shaped support frame respectively and rotates around the two ends respectively; one end of a moment arm of the n-shaped support frame is hinged with four hinging bases positioned on a pedestal cross beam respectively and rotates around the hinging bases; the upper end shafts of the n-shaped support frame are provided with shaft connecting lugs at intervals; two ends of a synchronous support frame are connected with the shaft connecting lugs in the n-shaped support frame through a connecting shaft respectively; and the fixed end of a motor push rod retractable device is hinged with the hinging bases on the bed frame, while the retractable end is hinged with the hinging base on the cross beam at one end of the synchronous support frame. The liftable medical nursing bed has the advantages that a four-point hinge mechanism consists of the motor push rod retractable device, the n-shaped support frame and the synchronous support frame not only achieves the aim of using one motor push rod to control the rising and the falling of the whole bed frame, but also has stable and reliable rising and falling speed.

Description

technical field [0001] The invention relates to a liftable medical nursing bed which can use a motor to control the automatic lifting of the bed surface, and belongs to the field of medical equipment manufacturing. Background technique [0002] CN2294719Y, title "a lifting nursing bed", including a base frame, a bed frame, and a movable bed board. It is characterized in that: the bed frame and the base frame are connected by a front frame and a rear frame. The bottom frame is connected by a chute, and there is a tension spring on the cross frame of the front frame and the rear frame to connect with the bed frame. There is a transmission box at the rear end of the bed frame. Two rotating heads drive the screw mandrel on the front frame and the screw mandrel on the rear frame, and the screw mandrel drives the lifting of the front frame and the rear frame. Its shortcomings: first, the lifting mechanism cannot realize the overall lifting of the bed frame; second, the screw mech...
