Abstract
A transmission device for a bed driver belongs to the technical field of automatic driving devices for the inclination or rising of a bed surface bottom support of an electric bed, and mainly comprises a shell (1) with a chute (3), a motor (9) fixed in the shell (1), a linear telescopic mechanism and a speed reducing mechanism which are arranged in the chute (3), and the like. The linear telescopic mechanism consists of a screw rod (7), a push block (2) and the like, and the speed reducing mechanism consists of a worm wheel (6), a worm (5) and the like; the worm (5) and the output shaft of the motor (9) are integrated. The utility model relates to a rationally, the adoption is by the reduction gears that the worm gear constitutes and the sharp telescopic machanism who comprises lead screw and ejector pad, has small, compact structure, and convenient to use, characteristics such as the maintenance of being convenient for have effectively improved drive ratio, have reduced transmission noise. The driver for the automatic lifting electric bed matched with the utility model can bring labor saving, convenience and comfort for the old, the weak, the sick and the disabled, the inpatients and the normal people at home.
Description
Technical field
This utility model relates to a kind of bed used driver actuating device, belongs to the automatic drive technical field that electric bed bed surface collet tilts or raises.
Background technology
The senior ward electric bed of more present families, hospital, the driving device that has a bed surface collet automatic lifting, it has the corresponding bed surface in the back that can make the human body implantation and digs angled automatically and/or the corresponding bed surface of human body lower limbs is raised the function of certain angle.Chinese patent CN2559269Y " automatic-lifting type electric bed " has disclosed a kind of bed surface collet automatic lifting driving device, comprise the lifting limited support on the bedstead crossbeam, be fixed on the motor driving shaft between longeron, rocking arm on the driving shaft and flexible connection piece, the bed surface backboard is connected with bedstead by fixed axis, be welded with trough plate on the bed surface backboard; the pulley on the rocking arm termination places in the channel suspending rail of trough plate; motor is installed on the electric machine support of bedstead, link to each other with flexible connection piece on the driving shaft by feed screw nut's sleeve.
This class bed surface collet automatic lifting driver has almost occupied a following whole space, it and bedstead closely link together, because this structure, to bring following problem: the employed material of driving device is more, manufacturing cost is higher, bother during maintenance cost, particularly when maintenance, need the bed of rising of long period to make troubles the old,weak,sick and disabled personnel.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and it is little to have a volume, and compact conformation is easy to use, is convenient to the bed used driver actuating device of characteristics such as keeping in repair.
This utility model is the bed used driver actuating device, comprise shell, be fixed in the motor in the shell, it is characterized in that the interior correspondence position with motor of shell also is provided with chute, be provided with the linear telescopic mechanism that constitutes by screw mandrel and pushing block in the chute, the reducing gear that constitutes by worm gear and worm screw; The output shaft of described worm screw and motor is all one.
Also can be provided with the screw that is combined together with wire rod thread on the described worm gear.
Described pushing block can be fixedlyed connected with the front end of screw mandrel.
Also can be provided with on the described shell and the corresponding limit switch of screw mandrel, can limit the position, stroke top and the end-of-travel position of pushing block in each linear telescopic mechanism.
This utility model is reasonable in design, adopts the reducing gear be made up of worm and gear and by the linear telescopic mechanism that screw mandrel and pushing block constitute, and it is little to have a volume, and compact conformation is easy to use, is convenient to characteristics such as maintenance, has effectively improved gear ratio, has reduced rotational noise.With the electronic bed used driver of the matching used automatic lifting of this utility model, the old,weak,sick and disabled person, inpatient and the normal person who can be family brings and saves labour, convenience and comfortable.
Description of drawings
Fig. 1 is a Facad structure cutaway view of the present utility model;
Fig. 2 is a plan structure cutaway view of the present utility model.
Among the figure: 1 shell, 2 is pushing block, and 3 is chute, and 4 is the screw on the worm gear, and 5 is worm screw, 6 is worm gear, 7, be screw mandrel, 8 is stroke dog, and 9 is motor, and 11,10 is limit switch.
The specific embodiment
This utility model is fixed in the motor 9 in the shell 1 mainly by the shell 1 of band chute 3, places formations such as linear telescopic mechanism in the chute 3 and reducing gear.
Linear telescopic mechanism is made of screw mandrel 7 and pushing block 2 etc., and reducing gear is made of worm gear 6 and worm screw 5 etc.; Worm screw 5 is all one with the output shaft of motor 9, and screw mandrel 7 is connected with threaded engagement on the worm gear 6 of being with screw 4, and pushing block 2 is fixedlyed connected with the front end of screw mandrel 7, and an end of screw mandrel 7 also is provided with stroke dog 8.Also be provided with on the shell 1 and screw mandrel 7 corresponding limit switches 10,11, can limit the position, stroke top and the end-of-travel position of pushing block in each linear telescopic mechanism.
During work, press the rising button of peripheral hardware hand controller, motor 9 must electricly just change, and through reducing gear and linear telescopic mechanism driving, it is overhanging to promote pushing block 2, and the rocking arm on the bed surface collet is rotated, and the bed surface collet raises gradually.When collet rose to the extreme higher position, if the rising button in the hand controller was pressed and do not put this moment, pushing block 2 arrived end-of-travel position, and at this moment the stroke dog 8 that is connected with screw mandrel 7 is stirred limit switch 11, made the rotation that has a power failure of motor 9 dead electricity.At this moment, the bed surface collet is parked in the extreme higher position, and this bed surface collet is in obliquity with bed in other words.
In the time the bed surface collet that raises need being descended, as long as press the decline button of hand controller, motor 9 gets electric counter-rotating, through reducing gear and linear telescopic mechanism driving, make pushing block 2 retractions, the bed surface collet rotates by the rocking arm that contacts with pushing block 2 under its deadweight effect, the bed surface collet is descended gradually, until dropping to the normal position.When if the bed surface collet has been reduced to flat position, also do not unclamp the button of pressing, at this moment pushing block 2 has arrived the pushing block end-of-travel position, and the stroke dog 8 that is connected with screw mandrel 7 has been stirred lead limit switch 10, makes direct current generator 9 dead electricity stalls.
