Description

Backrest on a kind of folding bed

Technical field

The utility model is related to a kind of bedding, particularly relates to backrest on a kind of folding bed.

Background technology

The patient for lying up, after long-time is liied in bed general fatigue can be felt, generally required in bed by stopping in bed Breath, existing sick bed can suitably shake head of a bed part, but because the quilt on bed is thicker, be cut the angle that the head of a bed is lifted Weak, though being in ramped shaped, patient often glides, it is impossible to be comfortably seated on bed.

Utility model content

For above-mentioned situation, the utility model discloses backrest on a kind of folding bed, it is to set one kind in bed Comfortable backrest, can suitably adjust the inclined degree of backrest, and have boosting mechanism, can more easily adjust, can be effective Mitigate the phenomenon ached all over of user.

In order to achieve the above object, backrest on a kind of folding bed that the utility model is provided, including：Folding bedstead, Mattress, base and lifting device；It is characterized in that：The folding bedstead, including rotating shaft and the upper bed board that connected by the rotating shaft With lower bed board, there is headrest the side relative with rotating shaft on the upper bed board, the pole for having activity below upper bed board；The mattress is put down It is layered on the folding bedstead；The base is the rectangular frame for having the teeth groove that can hold the pole termination above, on base A side vertical with teeth groove is arranged in the rotating shaft of the folding bedstead；Its two ends of the lifting device are connected to folding On the upper bed board of folded bedstead and base, can be by the upper bed board jack-up of folding bedstead, and with the axis of rotation of folding bedstead.

Further, the headrest on the upper bed board is to be flexibly connected with upper bed board, and headrest can be with adjustment angle.

Further, the lifting device is hinged the rhombus framework for surrounding by four connecting rods head and the tail, and its a pair relative Summit be hinged with upper bed board and base respectively, another opposite vertexes are connected to a spring.

Further, the spring on the lifting device is movably connected on rhombus framework, and spring can be from the lifting Dismantle on the rhombus framework of device.

The beneficial effects of the utility model are：Construction is ingenious rationally, is easy to use comfortable, and operation is also easier, can Angle of inclination is arbitrarily adjusted as needed, is adapted to bed patient and all crowds for liking reading a book on bed, working use； Lifting device can play power-assisted when upper bed board is folded and act on, convenient use person's every day use, meanwhile, the bullet on lifting device Spring can be dismantled, and when the utility model long-time is not used spring is pulled down, and can allow spring uses is more long.

Specific embodiment

The utility model is done with reference to Fig. 1 specifically describes backrest on a kind of folding bed, including：Folding bedstead 1, bed Pad 6, base 3 and lifting device 5；It is characterized in that：The folding bedstead 1, including rotating shaft 13 and by the rotating shaft 13 connection Upper bed board 11 and lower bed board 12, there is headrest 2 side relative with rotating shaft 13 on the upper bed board 11, and upper bed board 11 has activity below Pole 4；The mattress 6 is laid on the folding bedstead 1；The base 3 is that have that the termination of the pole 4 can be held above The rectangular frame of teeth groove a, side vertical with teeth groove on base 3 is arranged in the rotating shaft 13 of the folding bedstead 1；It is described Its two ends of lifting device 5 are connected on the upper bed board 11 of folding bedstead 1 and base 3, can be by the one of folding bedstead 1 The jack-up of bed board 11, and the rotating shaft 13 with folding bedstead 1 rotates.

Wherein, the headrest 2 on the upper bed board 11 is to be flexibly connected with upper bed board 11, and headrest 2 can be with adjustment angle.

Wherein, the lifting device 5 is hinged the rhombus framework for surrounding by four head and the tail of connecting rod 51, and its a pair relative Summit is hinged respectively with upper bed board 11 and base 3, and another opposite vertexes are connected to a spring 52.

Wherein, the spring 52 on the lifting device 5 is movably connected on rhombus framework, and spring 52 can be from the lifting Dismantle on the rhombus framework of device 5.

Above example only not limits technical scheme described in the invention to illustrate the present invention；Therefore, although This specification with reference to each above-mentioned embodiment pair present invention has been detailed description, but, the ordinary skill of this area Personnel should be appreciated that and still the present invention can be modified or equivalent；And all without departing from the present invention spirit and model The technical scheme enclosed and its improvement, it all should cover in scope of the presently claimed invention.
