Abstract
The utility model discloses a hand bed with adjustable a mattress, which is used for patients to sit, lie and recline. The utility model comprises a bedstead, a bed plate and a hand driving device that can regulate the inclined angle of the bed plate, wherein, the screw nut of the driving device is rotatablely connected with a driving rod. A locating slide block is arranged on the driving rod and contacts the screw nut tightly. An elastic circlip is buckled on the locating slide block. When the spacing point of the screw rod contacts the screw nut and the screw rod is shaken by force, the screw rod and the screw nut can overcome the elastic force of the circlip and slide corresponding to the slide block. Thus, the abrasion and seizure phenomenon of the screw rod and the thread of the screw nut can be overcome. The service life of the hand bed with adjustable mattress can be prolonged.
Description
This utility model relates to the medical health equipment that a kind of patients uses, especially a kind of Hand bed with adjustable mattress that can make patient sit, crouch, lie and use.
At present, the sick bed that domestic and foreign hospitals or family use generally adopts bed board flexible sick bed, by the hand adjusting device that links to each other with bed board, regulate the bed board gradient, patient can be sat or for sleeping in or lie.Hand adjusting device has one end and the hinged drive link of adjustable bed board.The other end of this drive link has a fixed screw, and rotating screw mandrel is arranged in the screw, and screw mandrel can be fixed with bedstead by a rotating block set.When rotation is connected in wind on the screw mandrel, just scalable between drive link and block set.This class Hand bed with adjustable mattress is when regulating the bed board gradient, because patient or other people hand undue force can make when the spacing place of screw mandrel contacts with screw in the hand adjusting device, also continuing firmly, thereby cause the screw thread on screw mandrel or the screw to be worn, or both are killed, and make adjusting device malfunctioning.
The purpose of this utility model provides a kind of improved Hand bed with adjustable mattress, and it can effectively overcome in the hand process because of undue force makes hand adjusting device malfunctioning, thereby prolongs the service life of sick bed.
The Hand bed with adjustable mattress that this utility model provides comprises bedstead, at least one bed board that movable bed board constitutes, the hand crank transmission device at adjusting bed board inclination angle.This hand crank transmission device has a hand screw mandrel, screw is arranged on the screw mandrel, screw places on the endoporus of drive link one end, and be rotatably connected with drive link, have a circumferential groove and at least one and the corresponding positioning sliding block of circumferential groove on the external cylindrical surface of screw at least, its shape is arranged on the drive link, size, the corresponding hole of quantity and positioning sliding block, slide block places in the above-mentioned hole, match with the groove on the face of cylinder of screw, an elastic circlip is buckled on the slide block, and slide block is closely contacted with screw, when screw mandrel turns to spacing place when contacting with screw, if continue firmly to shake screw mandrel, make screw mandrel and screw begin relative slide block and slide along the circumferential groove of screw.
Adopt above rational structure like this, no matter can reach patient or other people all can not make hand adjusting device malfunctioning when using hand adjusting device to regulate the bed board gradient, because when the bed board of flexible is transferred to level or inclination maximum, firmly shake screw handle again, can make the screw that links to each other with screw mandrel overcome the relative slide block circumferential slippage of elastic circlip elastic force, thereby alleviate the axial contact force of screw mandrel and screw screw thread junction, reduce thread abrasion, effectively overcome and kill phenomenon, prolonged the service life of Hand bed with adjustable mattress.
Below in conjunction with accompanying drawing its structure is described further.
Fig. 1 is the structural perspective of this utility model Hand bed with adjustable mattress.
Fig. 2 is the hand crank transmission device sectional side elevation in the Hand bed with adjustable mattress.
Fig. 3 is the profile of Fig. 2 along A-A.
As shown in Figure 1, this utility model Hand bed with adjustable mattress comprises 1, three movable bed board 3a of bedstead, 3b, two hand crank transmission device 2a of bed board that 3c constitutes and adjusting bed board gradient, 2b.
Bedstead only rolls device etc. by the external crucible back of the body, the back bed back of the body, bed frame, cabinet base, bedsie card and castor, castor and forms (marking among the figure).
As Fig. 2, shown in Figure 3, hand crank transmission device comprises wind 4, with the fixed cover for seat 5 of bedstead, screw 7 is arranged on the screw mandrel 10, screw 7 places in the vestibule of drive link 11 1 ends, and it is rotatable, there are three circumferential grooves 9 to reach and circumferential groove 9 corresponding positioning sliding blocks 8 on the screw 7, its shape is arranged on the drive link 11, size, the corresponding hole 14 of quantity and positioning sliding block, positioning sliding block 8 places in the hole 14, match with the circumferential groove 9 on the screw 7, an elastic circlip 13 is buckled on the slide block 8, and slide block 8 is closely contacted with screw 7, when screw mandrel 10 wrapping wire mothers 7 turn to banking pin 6 or 12, can make the screw 7 that links to each other with screw mandrel 10 overcome the elastic force of elastic circlip 13, relative localization slide block 8 slides.
