Description

A kind of lifting bed

Technical field

It is all that the utility model relates to a kind of bed, the lifting bed that the tortuous lifting of particularly a kind of adjustable bed surface is suitable for seeing TV, listens to the music, reads and read newspaper, lie fallow.

Background technology

Bed all is a requisite apparatus during people live, yet the widely used bed in places such as family, hotel, hospital all generally all is to lie low bed all.Along with the raising that people require the daily necessities comfort level, also wish to see TV in bed, listen to the music, read read newspaper, activity such as leisure, the existing this bed that lies low all can not satisfy the new demand of people.For the inpatient, bed also needs head and shank rising too long afterwards or keeps flat, and avoids extremity numbness.Some lifting beds that occurred at present are hand-rail type lifting bed, and heavy patient oneself is difficult to operation, and needing the nursing staff to shake wastes time and energy, and function singleness, can only control the angle variation of bed surface back part, and can not regulate and control the rising of shank or set level.

Summary of the invention

Goal of the invention of the present utility model is: at the problem of all product existence of present bed, can see TV in bed for the user provides a kind of people, listen to the music, read and read newspaper, lie fallow, oneself operate and just can make the bed surface bending, rotate, thus the lifting bed of change human body bed posture.

Goal of the invention of the present utility model realizes by implementing following technical proposals:

A kind of lifting bed, formed by mattress, the bed board that is arranged on mattress base, the driving mechanism that places ground bed case and support bed board to bend lifting, it is characterized in that: the bed board of described mattress base is combined by these three flat boards of legs and feet plate of the backboard, seat and the storing legs and feet that wait width; The described ground bed case that places is fixed with the crossbeam sleeve pipe that is fixed with pair of supporting on a case left and right sides inwall of a motor Xiang ， And at backboard and seat binding site place respectively respectively in the backboard and the legs and feet board position of its left and right sides inwall; The driving mechanism of described support bed board bending lifting comprises the motor that is contained in the motor case, is fixed on tube chamber wall on the motor output shaft and is shaped on the connection loop bar of internal thread, is inserted in by surperficial external thread sleeve and connects on the loop bar rake shape bracing frame that can be connected by rotating shaft along the screw rod of making horizontal rectilinear motion in its chamber, with the screw rod external end head; Two terminations about described rake shape bracing frame entablature are overlapped respectively in the crossbeam sleeve pipe on the left and right sides inwall that is inserted in a case.

Additional technical feature is:

Flexible connection between the backboard of 1. described composition bed board, seat and legs and feet plate is the opening of hinge, roll over and be connected.

2. the connection loop bar on the described motor output shaft is for the surface is provided with the oil storage connection loop bar that through hole is communicated with the interior reservoir oil pocket.

3. the connection loop bar of described motor output shaft, its outer wall is set with the bearing box that holds self-aligning bearing.

4. the rake shape bed board support stringer on the described rake shape bracing frame, the termination of each support stringer is provided with the supporting lug with the vertical quadrature of longeron.

5. described rake shape bracing frame is fixed with buttress brace between its power rail and support stringer.

6. travel switch is set on motor.

The beneficial effects of the utility model are: by about two driven by motor rake shape bracing frames realize that respectively the backboard in the bed board and the lifting and the angle of seat change, make people's back and shank can obtain lifting, make whole bed board and body curve corresponding, be convenient for people to see TV in bed, listen to the music, read and read newspaper and lie fallow; Also be convenient to bed patient oneself operation and adjust the berth posture; In oil storage connection loop bar, inject lubricating oil by oil filler point, make screw rod directly be in lubricating status, improved service life; Travel switch on the motor is closed down when reaching the limit of the position automatically, and safety is easy to operate.

The specific embodiment

Embodiment: a kind of lifting bed

As Fig. 1, Fig. 2, shown in Figure 3: this routine lifting bed, formed by mattress 1, the bed board that is arranged on mattress base, the driving mechanism that places ground bed case 19 and support bed board bending lifting.

The bed board of described mattress base is connected by hinge (5,3) and is combined into one by the backboard 6 that waits width, seat 4 and legs and feet plate 2 these three flat boards of putting legs and feet;

The described ground bed case 19 that places, backboard 6 and legs and feet plate 2 positions at its left and right sides inwall are fixed with respectively on bed case 19 left and right sides inwalls of a motor case 8 And at backboard 6 and seat 4 binding site places, are fixed with the crossbeam sleeve pipe 24 of pair of supporting respectively;

The driving mechanism of described support bed board bending lifting, comprise the motor 8 that is contained in the motor case 7, be fixed on the oil storage that tube chamber wall on motor 8 output shafts is shaped on internal thread and connect loop bar 11, be sleeved on oil storage and connect the bearing box 10 that holds self-aligning bearing 9 on loop bar 11 outer walls, being inserted in by surperficial external thread sleeve can be along the screw rod 15 of making horizontal rectilinear motion in its chamber on the oil storage connection loop bar 11, the rake shape bracing frame that is connected by rotating shaft 25 with screw rod 15 external end heads, two terminations about described rake shape bracing frame entablature 20 are overlapped respectively in the crossbeam sleeve pipe 24 on the left and right sides inwall that is inserted in a case 19;

Rake shape bed board support stringer 23 on the described rake shape bracing frame, its termination is provided with the supporting lug 18 with longeron 23 vertical quadratures, this supporting lug 18 acts directly on each position of lateral middle of backboard 6 bottom surfaces, and each position of horizontal front end of seat 4 bottom surfaces;

Described rake shape bracing frame is fixed with buttress brace 21 at its

power rail

22 and 23 of support stringers;

Described motor 8 is provided with travel switch, closes down automatically when backboard or seat reach the limit of the position.

The regulation process of the utility model lifting bed is as follows:

The regulation and control of A, backboard attitude position: the motor 8 that starts the backboard driving mechanism, the output shaft 12 of motor 8 drives oil storage and connects loop bar 11 rotations, dress is inserted in the screw rod 15 on the oil storage connection loop bar 11, connect along oil storage and to do rectilinear motion in the loop bar chamber and drive power rail 22 and make 17 rotations of rake shape bracing frame, supporting lug 18 on rake shape bracing frame 17 upper support longerons 23 terminations promotes backboard 6 liftings, and the travel switch controlled motion stops when reaching the limit of the position; Recovery Process is: motor 8 drives oil storage and connects loop bar 11 counter-rotatings, and screw rod 15 drives 17 counter-rotatings of rake shape bracing frame and is returned to original position.

The regulation and control of B, seat attitude position: as shown in Figure 3, the regulation process of its regulation process and backboard attitude position is basic identical, difference only is: in the seat driving mechanism, the supporting lug on the support stringer termination of rake shape bracing frame is to promote seat lifting or decline.
