The assembly structure of the medical bed according to the present invention is configured such that the mat frame 300 can be easily separated and assembled and its assembling structure is robust so that the worker can transport and install the medical bed alone and enhance durability. FIG. 1 is a perspective view of a medical bed according to a first embodiment of the present invention; FIG.

The base unit 100 is disposed below the intermediate frame 200 so that the intermediate frame 200 is spaced apart from the ground by a predetermined height. As shown in FIG. 1, a plurality of feed wheels 120 And a height adjuster 110 for controlling the lifting and lowering of the intermediate frame 200 may be further provided.

Although not shown, the base 100 may be fixedly mounted to support the intermediate frame 200.

The middle frame 200 is fixed to the upper portion of the base 100 and has a quadrangular frame structure in which a pair of vertical bars 210 and a horizontal bar 220 are connected to each other as shown in FIG. And at least one reinforcing bar 230 connecting the pair of lifting bars 210 as shown in the drawing may be further constructed.

At this time, the vertical bar 210 has a relatively longer length than the horizontal bar 220 as shown in the figure, and the horizontal bar 220 is vertically connected between the ends of the vertical bar 210.

The mat frame 300 is coupled to the intermediate frame 200 by the coupling means 400 in a state of being seated on the upper portion of the intermediate frame 200. As shown in FIGS. 1 and 2, The upper portion may be provided with a plurality of throttle plates 301 that support the mattress and are configured to adjust the angle of the mattress.

In this case, three of the throttle plates 301 are connected to each other by a link structure as shown in the left side of FIG. 1 to adjust the height of the lower body of the user, and one of the relatively long throttle plates 301 And may be configured to adjust the height of the body of the user.

Hereinafter, a specific embodiment of the mat frame 300, which is an embodiment of the present invention, will be described with reference to FIGS. 2 and 5. FIG.

2, the first frame 310 and the second frame 320 are coupled to each other so that the first frame 310 and the second frame 320 are coupled to each other, By separating the frame (310) and the second frame (320) and dispersing the load and the volume thereof, the working efficiency in transportation and installation can be greatly improved.

In general, a mat frame 300 configured to support a mattress according to a characteristic of a bed made larger than a person's key also has a large load and a large volume, so that the mat frame 300, which is integrally manufactured, In particular, work efficiency is significantly reduced in a narrow passage or in a curve section.

Thus, the mat frame 300 can be separated into the first frame 310 and the second frame 320, and the first frame 310 and the second frame 320 can be assembled and completed, It is possible to convey the mat frame 300, which is separated from the floor panel 320, particularly in a narrow corridor or a curved section. The first frame 310 and the second frame 320, which are separated from each other when assembled with the intermediate frame 200, can be sequentially assembled to the intermediate frame 200. As a result, It can be greatly improved.
