A kind of bent leg mechanism for nursing bed

Technical field

This utility model is related to the technical field of armarium, more specifically, it relates to a kind of song for nursing bed Leg mechanism.

Background technology

The whole world has various paralytics 46,000,000 at present according to statistics, and wherein panplegia patient is 21,000,000.Nursing paralysis disease People is relatively difficult, especially nurses panplegia patient.To be stood up once by least two nursing stafves side rib per 4 hours, per 1O Individual hour wants nursing staff to help its defecation once, also wants clear Xian after an action of the bowels.Patient's heart is therefore very painful, and its household is not yet Bear heavy burden.Also life is difficult the patient for taking care of oneself and handicapped old people, also to face same predicament more, this kind of at present The nursing of patient and old people is relied primarily on manually, and nursery work is very heavy.

For the problems referred to above, medical care art nursing bed, traditional nursing bed include bedstead and are placed on bedstead Lathe bed, lathe bed include back mobile bed plate, buttocks bed board and the leg movements bed board for rotating connection successively, are to improve patient to use The comfort level of nursing bed, back mobile bed plate and leg movements bed board can be lifted, but the leg movements of traditional nursing bed Bed is lifted for process skew formula, it is impossible to adjust patient legs' active state.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of simple, operation rational in infrastructure Stable, the achievable bent leg mechanism that patient legs are carried out with upper bent lower limb stretching and lower bent lower limb flexion.

For achieving the above object, this utility model provides following technical scheme：

A kind of bent leg mechanism for nursing bed, including bed body, the bed body include bedstead and the lathe bed being placed on bedstead, The lathe bed includes back mobile bed plate, buttocks bed board and the leg movements bed board for rotating connection successively, and bedstead is provided with driving The bent leg mechanism of leg movements bed board lifting, the bent leg mechanism are placed in the lower section of leg movements bed board, bent leg mechanism include with Kinematic link and be used to drive kinematic link push-and-pull leg movements bed board to carry out bent lower limb and lower song that leg movements bed board connects The electric pushrod of lower limb activity, the outfan and kinematic link of electric pushrod are connected.

This utility model is further arranged to：The leg movements bed board includes the upper bent plate and lower bent plate for rotating connection, The kinematic link includes the first drive link being hinged and the second drive link, on the first drive link relative to the first drive link Connection end be hinged with buttocks bed board, the other end of the second drive link and lower bent plate are fixed.

This utility model is further arranged to：The kinematic link is provided with two pieces, and is respectively placed in leg movements bed board The both sides of lower surface.

This utility model is further arranged to：The lower surface of the lower bent plate is provided with adding for the connection of the second drive link Strong pipe fitting, the reinforcement pipe fitting are hollow-core construction.

This utility model is further arranged to：Length of the length of second drive link less than the first drive link.

This utility model is further arranged to：On the leg movements bed board, the activity point of view of bent lower limb is 0-20 °, lower bent lower limb Movable corner be 0-60 °.

Contrast the deficiencies in the prior art, by using above-mentioned technical proposal the beneficial effects of the utility model：

Control panel input signal on nursing bed, control electric pushrod carry out push-and-pull, Jin Ershi to leg movements bed board The existing effect to bent lower limb and lower bent lower limb on the leg of patient.Upper bent lower limb is that electric pushrod promotes leg movements bed board to rise, and is realized Patient legs are formed with a tensile force, lower bent lower limb is that electric pushrod pulls leg movements bed board, as leg movements bed board leads to Cross bent plate and lower bent plate is hinged composition, it is movable relative to the first drive link by the second drive link on kinematic link, i.e., Drive lower bent plate relatively tortuous using the second drive link so as to form a bending force to patient legs, this kind of status architecture makes The ability that this nursing bed possesses functions of seat is obtained, the stool, urine of patient is facilitated, and aids in promoting patient legs' activity, Allow the patient to dredging the meridian.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the assembling structure schematic diagram of this utility model and lathe bed.

Specific embodiment

Reference picture 1- Fig. 2 is described further to embodiment of the present utility model.

This utility model other important component parts：As shown in Figure 1：Including bed body, bed body includes bedstead 1 and is placed in bedstead Lathe bed on 1, lathe bed include back mobile bed plate 23, buttocks bed board 22 and the leg movements bed board 21 for rotating connection successively, bed Frame 1 is provided with the bent leg mechanism for driving the lifting of leg mobile bed plate 21.

As shown in Figure 2：Bent leg mechanism of the present utility model is placed in the lower section of leg movements bed board 21, bent leg mechanism include and Kinematic link 3 and be used to drive 3 push-and-pull leg movements bed board 21 of kinematic link to carry out bent lower limb that leg movements bed board 21 connects With the electric pushrod 4 of lower bent lower limb activity, on leg movements bed board 21, the activity point of view of bent lower limb is 0-20 °, the movable corner of lower bent lower limb For 0-60 °, and being capable of start-stop at any time.The outfan and kinematic link 3 of electric pushrod 4 is driven and is fixed using connector.

Leg movements bed board 21 includes the upper bent plate 211 and lower bent plate 212 for rotating connection, and kinematic link 3 includes being hinged The first drive link 32 and the second drive link 31, relative to the connection end with the first drive link 32 and buttocks on the first drive link 32 Bed board is hinged, and the other end of the second drive link 31 and lower bent plate 212 are fixed.The length of the second drive link 31 is less than the first transmission The length of bar 32.

During the push-and-pull of electric pushrod 4, some transmission fulcrum in the middle of kinematic link 3 is the connection with buttocks bed board Place, in order to ensure the stability of the bending form of lower bent plate 212, the length of the second drive link 31 is arranged less than the first drive link 32 length.

To improve stability of the kinematic link 3 in push-and-pull leg movements bed board 21, therefore kinematic link 3 is provided with into two pieces, And it is respectively placed in the both sides of 21 lower surface of leg movements bed board.

The lower surface of lower bent plate 212 is provided with the reinforcement pipe fitting 5 for the connection of the second drive link 31, and the reinforcement pipe fitting 5 is Hollow-core construction.Strengthen pipe fitting 5 and resistance to compression and the structural stability for strengthening pipe fitting 5 is substantially increased using hollow-core construction.

Preferred embodiment of the present utility model is the foregoing is only, not to limit this utility model, the skill of this area Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model and should be included in guarantor of the present utility model In the range of shield.
