Abstract

The utility model relates to a self-extending pressure reducing bed board; a bed frame is provided with a guide rail; a movable slider is inlaid in the guide rail; the bed board on the back is connected with the movable slider by a supporting arm; the supporting arm is connected with the bed frame by a supporting connecting rod; the movable slider freely slides on the guide rail, so that the bed board on the back moves backwards along the guide rail while rising; the space is pre-reserved for the waist and abdomen to reduce extrusion force on the waist and abdomen, so that the waist and abdomen are more comfortable.

Description

The automatic extending decompression bed board

Technical field

This utility model relates to the automatic extending decompression bed board, belongs to the nursing bed technical field.

Background technology

Now the mobile bed plate of general on the market nursing bed is to prop up the position that back bed board or shank bed board change the people by push rod; But because of the rise of back bed board and shank bed board, the angle between two bed boards diminishes, and link position is constant, and the waist and belly that bed board is propped up the descendant is extruded, and is very uncomfortable.

Summary of the invention

The purpose of this utility model is the deficiency at said structure, provides a kind of and reserves the available buffer space at the corresponding health waist and belly of bed board, makes the back bed board prop up the back waist and belly and is not extruded, thereby reduce waist and belly pressure, more comfortable automatic extending decompression bed board.

For achieving the above object, this utility model has adopted following technical scheme: the automatic extending decompression bed board, on bedstead, be provided with guide rail, and be embedded with movable slider on the guide rail, be connected by supporting arm between back bed board and movable slider, be connected by bearing connecting rod between supporting arm and bedstead.

Compared with prior art, the utlity model has following beneficial effect:

(1) movable slider is contained on the guide rail and is free to slide, and the back bed board was moved along guide rail backward in the while of rising, and reserves the waist and belly space, reduces the waist and belly extruding force, and is more comfortable.

Fig. 2 is that this utility model back bed board is propped up the procedure structure sketch map.

Fig. 3 is that this utility model back bed board is propped up the back structural representation.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, automatic extending decompression bed board of the present utility model is by bedstead 1, back bed board 2, guide rail 3, movable slider 4, supporting arm 5, bearing connecting rod 6 constitutes, on bedstead 1, be provided with guide rail 3, be embedded with movable slider 4 on the guide rail 3,4 of back bed board 2 and movable sliders are connected by supporting arm 5, and 1 of supporting arm 5 and bedstead are connected by bearing connecting rod 6.

When push rod promotes 2 risings of back bed board, movable slider 4 along guide rail 3 from the front portion backward portion move, the gradient that back bed board 2 rises can be added to 75 degree from 0 degree freely to be increased, spacing between while back bed board 2 and the waist bed board increases gradually, corresponding amplification is between 35cm-135cm, because of the increase of spacing between back bed board 2 and the waist bed board, the patient's waist abdomen position that lies on a bed an and buffered space is arranged and unfold has reduced the extruding force of waist abdomen position.Prop back bed board 2 jointly because of supporting arm 5 and bearing connecting rod 6, structure is firm.Because of the spacing amplification between back bed board 2 and the waist bed board between 35cm-135cm, less than the length of guide rail 3, and the restriction of bearing connecting rod 6 is arranged, movable slider 4 can not skid off guide rail 3.In like manner, under push rod retreated active force, movable slider 4 moved to the front portion from the rear portion along guide rail 3, and the gradient of back bed board 2 can be spent to 0 degree from 75 and freely reduce, spacing between corresponding back bed board 2 and the waist bed board reduces from 135cm-35cm, until recovering to lie low the position.The visual patient's of gradient of back bed board 2 hobby is freely selected.

Claims (2)

1. automatic extending decompression bed board, by bedstead (1), back bed board (2), guide rail (3), movable slider (4), supporting arm (5), bearing connecting rod (6) constitutes, it is characterized in that: bedstead (1) is provided with guide rail (3), be embedded with movable slider (4) on the guide rail (3), be connected by supporting arm (5) between back bed board (2) and movable slider (4), be connected by bearing connecting rod (6) between supporting arm (5) and bedstead (1).

2. a kind of automatic extending decompression bed board according to claim 1, it is characterized in that: the gradient that described back bed board (2) rises can be added to 75 degree from 0 degree freely to be increased, and the spacing amplification between the waist bed board is between 35cm-135cm, less than the length of guide rail (3).
