Abstract
The present invention relates to a hung lifting bed, particularly to a bed used in life. The present invention is composed of a bed head frame, a flat plate frame, bed foot rims and a lifting mechanism and is characterized in that a nut screw mechanism is fixed on the bed head frame, a nut is movably sheathed on a lifting seat, two steel wire cables are fixed on both sides of the lifting seat and are hung on the bed foot rims of two edges through two pulleys on the bed head frame, and sliding pins are fixed at the upper part and the lower part of the nut and the upper position and the lower position of a screw. When a power shaft drives the screw to rotate, the nut is forced by friction and can not autorotate, and the lifting seat is forced to lift and pull the steel wire cables. Thereby, the bed head frame moves in a lifting mode, and the stress of the two edges is symmetric. When the bed head frame moves to a top position, two sliding pins carry out cross contact, the nut is forced to slide in the lifting seat which does not move, overload is avoided, and automation control is carried out conveniently.

Description of drawings: accompanying drawing is a structure chart of the present invention.
Fig. 1 is the slide nut untie-sell, and 2 is the screw rod sliding pin, and 3 is screw rod, and 4 is guide post, and 5 is shaft block ring, and 6 is elevating bracket, and 7 is steel wire rope, and 8 is nut, and 9 is pulley, and 10 is the screw rod bevel gear, and 11 is line shaft, and 12 is the line shaft bevel gear.
Embodiment: the present invention implements like this, suspension lifting bed by two bed head frames, a pallet, four cabinet base frames and elevating mechanism are formed, bed head frame is rectangular shaped as frame, both sides munnion inner side edge has elongated slot, two munnion hollow kinks are at two independently outside the cabinet base frame, the cabinet base frame also is the hollow shaped as frame, corresponding inner side edge also has elongated slot, one steady pin is arranged at the top, in the centre of the rectangular shaped as frame of bed head frame the bolt and nut structure is installed, screw rod top kink is in the intermediary bearing of last horizontal pane, in the rigid bearing of screw rod bottom kink infra horizontal pane and rise from the bearing external fixation bevel gear is arranged, following horizontal pane is fixed with pinion stand below the middle part, line shaft stretches into pinion stand, axle head is fixed with bevel gear and is meshed with the bevel gear of screw rod bottom, line shaft two is connected with both sides bed head frame pinion stand simultaneously, be with nut on the screw rod, nut overcoat has elevating bracket, there are two holes the elevating bracket both sides, there are two guide posts to pass this two hole and are fixed on bed head frame up and down between the horizontal pane, hang with two steel wire ropes about elevating bracket on the steady pin in two outsides, every steel wire rope is passed down through the guide post outside, fixed first pulley on the following horizontal pane, pass down fixed second pulley in horizontal pane and place, munnion right angle again, then turn to the elongated slot of crossing bed head frame munnion inboard obliquely and the elongated slot of the cabinet base frame of kink in munnion to hang on the steady pin of cabinet base arch.Nut and elevating bracket fixing means have two kinds, and a kind of is that nut cylindrical interference fit is fixed in the elevating bracket in the circle, when the elevating bracket seat pushes up up and down two positions, rely on stopping means to make the line shaft stall, or the dependence feel stop rocking arm like this.Another kind method is: in the nut kink is justified in elevating bracket, there is a chimb to contact below the nut with the elevating bracket base, nut top cylindrical protrudes elevating bracket and an inner groovy is arranged, be enclosed within the groove spacing with shaft block ring, upper and lower sides position at nut is fixed with the slide nut untie-sell respectively, and the next correspondence also is fixed with the screw rod sliding pin respectively on screw flight.
Line shaft can be used driven by motor, and line shaft can also be provided with the handle head motion simultaneously at both sides pinion stand correspondence position.And line shaft also can be provided with remote control unit under with the driven by motor situation.
When line shaft is rotated by manual control or machine control, the line shaft bevel gear drives the screw rod bevel gear and rotates, thereby screw rod rotates, since bed head frame gravity by wire rope transfers to elevating bracket, and on the chimb of elevating bracket base compressing below nut, make and produce big friction between the two, this power is greater than the screw thread frictional force of bolt and nut, make it be difficult for relatively rotating, so when screw rod rotates, though nut be kink in elevating bracket in the circle, can rotation, but under the screw rod compressing, move up and down yet, thereby pulling both sides steel wire rope, when steel wire rope upwards draws, because steel wire rope is to be fixed on the steady pin of cabinet base arch by the pulley other end, then along with the rising of elevating bracket, force bed head frame to do ascending motion with respect to the cabinet base frame, because line shaft is connected with the pinion stand of both sides bed head frame, the structure of two bed head frames is again the same, and then two bed head frames rise synchronously.In like manner, during from the decline of line shaft control elevating bracket, bed head frame descends automatically owing to action of gravity.
The spacing mechanism of skidding is running like this: when elevating bracket rises to the bottom, slide nut untie-sell rising on the nut intersects with the screw rod sliding pin and contacts, this moment, screw rod was by two intersection sliding pins, the torsion that passes to nut is greater than the friction between nut chimb and the elevating bracket, force nut along with one of screw rod moves in a circle, the cylindrical of nut middle part cylindrical and elevating bracket interstitial hole is owing to be that clearance fit is then done the rotation of skidding, elevating bracket also just can not rise, avoided line shaft because of traffic overload problem out of control, when controlling especially automatically, avoid motor to burn out.In like manner, when elevating bracket dropped to the end, the contact of two sliding pins intersection causes skidded.
