Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to the embodiments are included in the scope of the present invention.

This embodiment provides a scalable sick bed 100, including support 1, set up the bed board 2 on support 1, support 1 includes frame 11, undercarriage 12 and support a plurality of support frames 13 that can stretch out and draw back in vertical direction of frame from top to bottom, 2 one sides of bed board still are provided with straining device 3, scalable sick bed is still including fixing the electric putter 4 on support 1, electric putter 4 is including being fixed in first fixed plate 41 and the second fixed plate 42 on the support, fixedly connected with lead screw 43 and a plurality of guide bar 44 between first fixed plate 41 and the second fixed plate 42, first fixed plate 41 one side still is fixed with driving motor 45. The first fixing plate 41 and the second fixing plate 42 are further respectively provided with a bearing device 46 for driving the screw rod 43 to move. The second fixing plate 42 is further provided with a movable plate 47 on a side facing the first fixing plate 41, and the movable plate 47 is sleeved on the screw rod 43 and the plurality of guide rods 44.

In the process of bed board expansion, driving motor drive bearing carries out the extension motion, under the effect of a plurality of guide posts, has guaranteed the stability of expansion direction, the error of the two expansion progress can not appear. In addition, through the fly leaf of installing additional, further strengthened the stability of guide post and roller, the phenomenon such as dislocation, rocking can not take place for the position in the expansion process.

Straining device 3 transversely sets up in one side of bed board 2, straining device 3 is including transversely setting up in the roller bearing 31 of bed board 2 one side, straining device 3 is still including setting up side by side in the tensioning axle 32 of roller bearing 31 one side.

The tensioning mechanism 3 further comprises an upper fixing block 33 and a lower fixing block 34 for fixing the roller 31 and the tensioning shaft 32. The roller 31 and the tension shaft 32 are fixed at both ends by the upper and lower fixing blocks.

The tensioning mechanism 3 further comprises a motor 35 fixed on the upper fixing block 33, and a first gear 36 and a second gear 37 for connecting the driving roller 31 to rotate. The upper fixing block 33 and the lower fixing block 34 are further provided with symmetrical adjusting holes 38, and adjusting blocks 39 which are fixedly connected with the upper end and the lower end of the tensioning shaft 32 and can slide in the adjusting holes 38 are arranged in the adjusting holes 38. In the process of unfolding the bed board to one side, the motor 35 drives the first gear 36, the first gear 36 drives the second gear 37 to rotate, and the roller 31 also rotates under the action of the second gear 37. In the process, as the bed plate moves under load and the contact area between the two ends of the bed plate and the support is gradually reduced along with the expansion of the bed plate out of the support, the load borne by the connection part is continuously increased.

The telescopic sickbed also comprises an anti-toppling mechanism 5 arranged at the bottom of the lower frame 12. The anti-toppling mechanism is arranged on one side of the bed plate 2 in the transverse direction in an inclined direction 5. In the in-service use in-process, consider that the bed board expandes to one side, for example to the left side, along with the in-process of expanding, the holistic center of disease and sick bed can slowly be to expanding the side skew, and in this time, anti-overturning mechanism can expand one side and move slowly to the bed board according to the skew of focus, provides new strong point for whole sick bed, guarantees under the whole focus of sick bed moves outward the condition, can not take place phenomenons such as toppling, upset.

The bed board 2 can be driven by the support frame 13 to extend up and down. The bed board 2 can move transversely under the drive of the electric push rod 4. And universal wheels 6 are arranged at four corners of the lower support. One end of the electric push rod 4 is fixedly connected with the bed board 2.

In the actual use process, when a patient needs to be moved transversely to a nuclear magnetic resonance or CT scanning table surface, the height of the sickbed can be adjusted firstly according to the height of the actual table surface, when the height is adjusted to a proper position, the bed plate is controlled to move slowly transversely, and when the sickbed is adjusted to the proper position, medical staff can move the patient on the sickbed to the table surface to carry out instrument scanning and other work. And in the process of slowly moving the bed plate transversely, the anti-toppling mechanism can slowly extend out according to the shift of the whole gravity center, so that the bed plate can not turn over due to the shift of the gravity center in the process of moving the bed plate transversely. In the whole process, medical personnel can easily move the patient to the working platform for scanning detection. In addition, the sickbed can automatically adjust the positions of the sickbed in the vertical and horizontal directions according to other specific use requirements, and is very simple and safe to operate.

The bed board 2 comprises a supporting frame 7, and a plurality of rollers 71 are arranged on the edge of the supporting frame 7 close to the unfolding side of the bed board 2. The supporting frame 7 comprises a supporting strip 72 which is transversely arranged, the supporting strip 72 divides the supporting frame 7 into a plurality of rectangular areas, and each rectangular area is provided with a supporting plate 73. In the actual use process, when the bed board is unfolded to a proper position and a patient needs to be transferred from the hospital bed to the scanning table, the patient can be transferred by medical staff with great effort, if the weight of the patient is heavier, the transfer process has certain risks, and in case that the strength of the medical staff is not enough, the patient is easily subjected to secondary damage. In another embodiment, the rollers may be arranged in a row or multiple rows, which is used to facilitate the patient's traverse.

Two connecting plates 74 are respectively arranged at two ends of the supporting frame 7 for connecting the supporting frame 7 to the bracket 1. Guide rails 75 are respectively arranged between the connecting plates 74 at the upper end and the lower end of the supporting frame 7.
