Description

Bed is with the self-service backrest of lying on the back

This utility model relates to a kind of self-service backrest of lying on the back of usefulness, and especially the bed of being made up of U-shaped seat back frame, backrest cover, axle, mechanical driving device, motor and control circuit is with the self-service backrest of lying on the back.

In the background technology, existing utensil of lying on the back when lying in bed for the people is the sick bed of a kind of ad hoc structure of using of hospital.The structure of this sick bed is that the bed body is divided into following, following two halves, the first half of bed body can be dug or fallen with mechanical driving device, has the two kinds of functions of lying on the back.The weak point of this sick bed is: 1. sick bed bed body is divided into fixed and movable two halves, the structure more complicated, and manufacturing cost is higher, can't popularize in hospital or family; When 2. using, the comparison heaviness of digging and fall of bed body the first half is required great effort, and patient can't oneself operate; When 3. the bed body was dug, bedding easily glided and moves; 4. after bed body the first half is dug,, the people is easily slided to both sides, be difficult to keep normal posture because of bed surface is smooth.

The purpose of this utility model is to overcome the weak point in the above-mentioned background technology, and a kind of self-service backrest of lying on the back that can be installed on easily on the various beds is provided, and the help that need not others during bed just can change position easily.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of self-service backrest of lying on the back of usefulness, comprise bedstead (5), its special character is: go up assembling at bedstead (5) and connect the backrest of controlling that rises and falls by actuating device (4), the backrest that rises and falls is by connecting backrest cover (2), U-shaped seat back frame (1) end assembled shaft (3) in the U-shaped seat back frame (1).

In the actuating device of the present utility model (4), lever (6) upper end connecting axle (3), the lower end connects steel wire (7), steel wire (7) other end attaching nut (9), fixed mount (8) is gone up the screw rod (10) of assembling and is gone up assembling removable nut (9), and screw rod (10) outer end connects crank (11).

In the actuating device of the present utility model (4), lever (6) lower end that the axle (3) of U-shaped seat back frame (1) is located to connect, connect steel wire (13), steel wire (13) other end is wrapped on the worm-wheel shaft (12), and the worm screw (16) that cooperates with worm gear (18) is connected with motor (15) output shaft.

In the actuating device of the present utility model (4), the axle (3) of U-shaped seat back frame (1) locates to connect fan-shaped ratchet (20), constitutes locking device by manual ratchet (21) and ratchet (20).

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1 is the structural representation of this utility model bed with self-service backrest;

Fig. 2 is the user mode figure of this utility model bed with self-service backrest;

Fig. 3 is that this utility model bed is manually controlled the embodiment sketch map with self-service backrest:

Fig. 4 is this utility model bed with self-service backrest automatic control system sketch map;

Fig. 5 is that this utility model bed is manually controlled another embodiment sketch map with self-service backrest.

Number in the figure is described as follows:

1-U shape seat back frame 2-backrest cover 3-axle 4-actuating device 5-bedstead 6-lever

Referring to Fig. 1, the backrest that rises and falls shown in Figure 1 is made up of U-shaped seat back frame 1, backrest cover 2, axle 3, and is connected with actuating device by axle 3, and U-shaped seat back frame 1 can adopt the pin-connected panel connection, and backrest overlaps 2 can adopt fabric sleeve.The effect of U-shaped seat back frame 1 is to support backrest cover 2, and it and the backrest cover 2 common backrests of forming hold up human body back.Backrest cover 2 is connected on the U-shaped seat back frame 1, and when backrest puts down when dropping on bed surface, backrest cover 2 is close on the bedding, becomes the part of a body, when lifting with U-shaped seat back frame 1 common composition backrest.Because backrest cover 2 is slightly recessed under the human body compressing, can make the human body natural keep normal posture, can not horizontally slip.Referring to Fig. 2, during use, adopt securing member that axle 3 is fastened on the bedstead 5, axle 3 can be axis or declutch shaft, and during work, actuating device 4 drives axle 3 and rotates, U-shaped seat back frame 1 rotates with axle 3, it can lifting in level and 85 degree angle ranges, and locking on can be in this scope arbitrarily angled, arbitrarily controls the backrest lifting.

Referring to Fig. 3, the enforcement illustration that Fig. 3 manually controls with the self-service backrest of lying on the back for bed, rotate crank 11 with hands, drive screw rod 10 motions, nut 9 corresponding sports also pass through steel wire 7 drive levers 6 and rotate, axle 3 also corresponding rotations drive 1 lifting of U-shaped seat back frame, control the lifting of U-shaped seat back frame 1 by the rotation direction that changes crank 11.Fig. 4 for bed with the self-service backrest automatic control system sketch map of lying on the back, open gauge tap 19, motor 15 begins to rotate and drive worm screw 16 is rotated, worm gear 8 corresponding rotations are also passed through steel wire 13 drive levers 6 and are rotated, axle 3 corresponding rotations, drive 1 lifting of U-shaped seat back frame, can control the lifting of U-shaped seat back frame 1 by the rotation direction that control box 17 changes motor 15.Another enforcement illustration that Fig. 5 manually controls with the self-service backrest of lying on the back for bed, U-shaped seat back frame 1 is raise slightly, with hands U-shaped seat back frame 1 plate is risen or puts down as required then, ratchet 20 side-to-side movements, when U-shaped seat back frame 1 fell, ratchet 21 blocks ratchet 20 and locking makes that U-shaped seat back frame 1 is fixing.For easy to carry, U-shaped seat back frame 1 also can adopt pin-connected panel to connect, and backrest cover 2 can adopt fabric sleeve.

Advantage of the present utility model and effect are as follows:

1. simple in structure, can be installed on easily on any bed, make the common bed accessory function of lying on the back, greatly reduce Use the cost of lie supine bed.

2. the bed patient can independently control digging and falling of backrest, has greatly alleviated medical personnel's labour intensity.

When 3. backrest falls, be as good as with common bed, can be used as common bed and use, when digging, bedding not with Backrest is dug and is slided, and has overcome in the past this class bed and has dug and make bedding mobile the bringing of gliding owing to a bed body first half Inconvenience.

When 4. backrest lifted, the people leaned against on the back-rest cover, and back-rest cover is slightly recessed, made human body be difficult for sliding to both sides And the maintenance normal posture, thereby guaranteed safety.
