Abstract

The utility model relates to a bed, particularly a health-care recovery bed used for long-term bedridden patients. The utility model is characterized in that a small rocker is pivoted in a bracket (1) suspended under the recovery bed, and both ends of the small rocker are respectively connected with an upper and a lower bed drawers which move straightly and vertically up and down; a plurality of separate diamond supporting blocks which are staggered mutually are arranged on the upper and the lower bed drawers. Therefore, the contacted position between the human body and a bed surface can be changed without turning over. The contact ventilation is favorable.

Description

Invalid bed specially for nursing

This utility model relates to a kind of bed, is particularly suited for the Invalid bed specially for nursing that the long-term bed patient uses.

At present, a kind of physiology body-building bed is disclosed in CN2091098U.It is to be spliced by the identical keyboard of two covers.Every cover keyboard drives each square key piece by power transmission shaft, cam, little axle, elevating movement, and square key piece shuttle thread contacts with the human body back blood vessel is vertical, be unfavorable for blood circulation, and its complex structure is difficult to popularize.

In view of this, the purpose of this utility model provides a kind of Invalid bed specially for nursing, with the back-up block of prismatic separately of two convertible contact human bodies, as supporting bed surface.

The purpose of this utility model is achieved in that it mainly comprises bed head frame, the tailstock frame, two longerons and bed board, it is characterized in that: the square hole hole of offering castellated edge on the bed board, under this square hole hole, be provided with the suspension bracket that is connected with its top under two longerons, in this support, be provided with the small swinging rod that articulates with its center, this small swinging rod two ends is respectively equipped with hinged act bar and connects on the work, in the following vertical translation, the drawer of leaving the bed, on the drawer of going to bed, be provided with the prismatic back-up block at many intervals, on the drawer of leaving the bed, be provided with the prismatic back-up block at many intervals of staggering again with the prismatic back-up block, in addition, on, the drawer of leaving the bed, on the outer rim of prismatic back-up block combination and the hole castellated edge corresponding matching of bed board.

Be provided with the big fork that articulates with its center and hinged in the above-mentioned support, again sliding fit one eccentric shaft on this big fork with a termination of one end head and small swinging rod.

Because adopt such scheme: human body need not stand up just can change the position that contacts with bed surface, and is in contact with one another the position well-ventilated.

Below in conjunction with drawings and Examples this utility model is further specified.

The cross-sectional schematic of Fig. 1 this utility model exemplary embodiments support;

The A-A cross-sectional schematic of Fig. 2 this utility model exemplary embodiments Fig. 1;

Fig. 3 this utility model exemplary embodiments schematic side view;

Fig. 4 this utility model exemplary embodiments schematic top plan view.

Among the figure: 1, support 2, motor 3, worm reducer 4, eccentric shaft

5, big fork 6, small swinging rod 7, the drawer 8 of going to bed, the drawer of leaving the bed

9, prismatic back-up block 10, act bar 11, prismatic back-up block 12, bed head frame

13, tailstock frame 14, longeron 15, rack shell 16, bed board

17, pin

Present embodiment comprises: bed head frame 12, tailstock frame 13, two longerons 14, bed board 16, two forks 5, four small swinging rods 6, get in and out of bed drawer 7,8 and on prismatic back-up block 9,11, shown in Fig. 1～4, wherein:

Two longerons, 14 two ends are connected on bed head frame 12 and the tailstock frame 13, and bed board 16 is supported on this two longeron 14, determine hole position, bed board 16 top with shop bolt 17, belong to prior art (as shown in Figure 3).

Offer the square hole hole of castellated edge on the bed board 16, be provided with the suspension bracket 1 that is connected with its top under two longerons 14 under this square hole hole, the rack shell 15 of sealing process is housed on this support in addition; Two of motor 2, the worm reducer 3 that is connected and worm gear connection thereof is installed on support 1 exposes eccentric shaft 4 (shown in Fig. 1,3).

Two big forks 5 are articulated on the support 1 with the centre, again with the elongated slot at two big forks, 5 off-center positions respectively with two eccentric shafts 4 (little axle) sliding fit, do synchronously upper and lower swings (as shown in Figure 1) thereby the eccentric rotary of eccentric shaft 4 drives two big forks 5.

Four small swinging rods 6 also are articulated on the support 1 with the centre, and a termination of small swinging rod 6 is hinged with a termination of big fork 5, thereby big fork 5 drives on the small swinging rod 6, lower swing, and the two ends of small swinging rod 6, respectively through vertical act bar 10 hingedly connect parallel on, the drawer 7 of leaving the bed, on 8, limit (not shown) with guide rail, make, the drawer 7 of leaving the bed, 8 do respectively, vertical down alternately translational motion, last, the drawer 7 of leaving the bed, the prismatic back-up block 9 that connects many intervals on 8 respectively, 11, and prismatic back-up block 9 (35) matches with prismatic back-up block 11 (24) and just in time forms a complete solid plane (cooperating the slit to disregard), be that prismatic back-up block 9 can be in the cavity on the drawer 8 of leaving the bed (the prismatic cavities that adjacent prismatic back-up block is 11), on, under pass freely through, on the contrary, prismatic back-up block 11 can be in the cavity on the drawer 7 of going to bed, on, under pass freely through; Thereby prismatic back-up block 9,11 alternately supports human body at sustained height at diverse location, and in addition, the combination outer rim of prismatic back-up block 9,11 is with 16 corresponding cooperations of top hole castellated edge of bed board, to guarantee and bed board 16 co-altitudes.
