A kind of beddo back craneTechnical field:
The invention belongs to household electric movable bed automatic adjustment technology field, relate to a kind of lifting assembly regulated for the beddo back utilizing controller to realize different parts lifting, in particular to a kind of beddo back crane, reduce motive force by being arranged on by pushing motor on the longer bed body underframe of distance to increase actuating length, thus realize the stable of back crane.
Background technology:
Along with socio-economic development and living standards of the people improve, the requirement of people to bed function is also more and more higher, beddo more and more appears at the places such as family, hospital, sanatorium, especially social senilization increases the weight of day by day, young man's rhythm of life is accelerated, the time of looking after old man is fewer and feweri, and the beddo of intelligent humanized design can play certain booster action to the life of old man.The benefit of beddo is a lot, such as beddo can help patient to sit up to lie down, patient left and right within the scope of 0 °-60 ° can be made to stand up arbitrarily, prevent bedsore from generating, assist and improve back lumbar vertebra disease problem, auxiliary quick penetration depth sleep, assists and improves respiratory disease, the interior also embedding toilet of the beddo even had, can help to relieve oneself etc.Therefore, Intelligent electric bed has good market prospects.In order to meet the different requirements of people, beddo requires lightly attractive in appearance, humanization designing, and the lifting that can meet people's different angles differing heights.In beddo, the lifting of back and head is the part that frequency of utilization is the highest, so the result of use of back lifting structure and firmness degree are for impact very large of beddo, the back lifting structure manufacturing cost of beddo is in the market high, structure complicated and heavy difficulty use, the back lifting structure even had is firm not, life cycle is shorter, thus affects the service life of whole beddo, likely damages user.Therefore, seek to design a kind of beddo back crane, reduce motive force by being arranged on by pushing motor on the longer bed body underframe of distance to increase actuating length, thus realize the stable of back crane, increase its life cycle, there are good market prospects.
Summary of the invention:
The object of the invention is to the shortcoming overcoming prior art, seek to design a kind of beddo back crane, motive force is reduced to increase actuating length by being arranged on by pushing motor on the longer bed body underframe of distance, thus realize the stable of back crane, increase the firmness of its entirety.
The agent structure of the beddo back crane that the present invention relates to comprises transmission arm, transmission base tube, motor bull stick, drive, rolls arm groove, pushing motor, bed board support bar, bed body underframe, back bed board and pushing motor connecting rod; Pushing motor is fixedly installed on the bed body underframe far-end of day font rigid structure, and pushing motor connecting rod is stretched out in pushing motor one end; Roll arm groove and be fixed on bed board both sides, back; Bed board support bar one end is fixedly installed on a body underframe, and one end is connected with back bed board rotary type in addition, to support bed board after bed board rises, reduces the suffered pressure of crane; The transmission arm of up-narrow and down-wide rigid structure is fixed on the two ends of transmission base tube, and drive is fixed on the free end of transmission arm and contacts with the corresponding arm trough roller dynamic formula that rolls; One end of motor bull stick is fixed on transmission base tube, and the other end is connected with pushing motor link rotatable formula; Pushing motor drives the elongation of pushing motor connecting rod and contraction thus traction motor bar rotation, realizes controlling the motion of transmission arm and drive is rolled rolling in arm groove, controlling the lifting of back bed board.
The present invention compared with prior art, its pushing motor arranges the far-end of the early bed body underframe that distance is longer, motor force stroke increases, motor force is diminished, thus promotes the holding capacity of this crane, ensure integrally-built stability, its life cycle is long, structure is simple, and principle is reliable, and applied environment is friendly.

Detailed description of the invention:
Below by accompanying drawing, also the invention will be further described in conjunction with the embodiments.
Embodiment 1:
The agent structure of the beddo back crane that the present embodiment relates to comprises transmission arm 1, transmission base tube 2, motor bull stick 3, drive 4, rolls arm groove 5, pushing motor 6, bed board support bar 7, bed body underframe 8, back bed board 9 and pushing motor connecting rod 10; Pushing motor 6 is fixedly installed on bed body underframe 8 far-end of day font rigid structure, and pushing motor connecting rod 10 is stretched out in pushing motor 6 one end; Roll arm groove 5 and be fixed on back bed board 9 both sides; Bed board support bar 7 one end is fixedly installed on a body underframe 8, and one end is connected with back bed board 6 rotary type in addition, to support bed board after bed board rises, reduces the suffered pressure of crane; The transmission arm 1 of up-narrow and down-wide rigid structure is fixed on the two ends of transmission base tube 2, and drive 4 is fixed on the free end of transmission arm 1 and contacts with corresponding arm groove 5 roller that rolls; One end of motor bull stick 3 is fixed on transmission base tube 2, and the other end is connected with pushing motor connecting rod 10 rotary type; Pushing motor 6 drives the elongation of pushing motor connecting rod 10 and contraction thus traction motor bull stick 3 rotates, and realizes controlling the motion of transmission arm 1 and drive 4 is rolled rolling in arm groove 5, controlling the lifting of back bed board 6.
