The top of the upper rod 310 is hinged to the middle of the lower portion of the union 200. The lower portion of the upper rod body 310 is provided with an internal threaded hole 311 in the axial direction thereof. The female screw hole 311 is screwed to the upper portion of the screw 330. The lower portion of the screw 330 is fixed to an output shaft of the first motor 340. The lower portion of the first motor 340 is fixed to the frame, the lower end of the guide bar 320 is fixed to the frame, and the upper bar body 310 moves longitudinally along the guide bar 320.

According to the present invention, it is preferable that the inclined part 400 includes a first crossbar 410, a second crossbar 420, and a curved guide rail 430. Wherein the first crossbar 410 is a downwardly concave arc-shaped bar, and the first crossbar 410 and the second crossbar 420 are identical in shape and symmetrically disposed in a staggered manner. The top parts of the first and second crossbars 410 and 420 are respectively connected to both sides of the lower surface of the link 200. The middle parts of the first cross bar 410 and the second cross bar 420 respectively move along two cambered surface guide rails, and the cambered surface guide rails 430 are fixed with the frame.

Referring to fig. 4 and 5, the connection part 500 includes a housing 551, a wire coil 561, a first permanent magnet 541, a first electromagnet 542, a second permanent magnet 543, a second electromagnet 544, a fixing rod 570, a first pull string 511, a second pull string 512, a first slider 531, a second slider 532, a first rail 533, a second rail 534, and a connection post 520. The upper surface of the first motor 340 is fixed to the lower end of the fixing lever 570, and the upper end of the fixing lever 570 is fixed to the housing 551. Through holes are formed in the lower portion of the left side face and the upper portion of the right side face of the shell 551, and a first pull rope 511 and a second pull rope 512 are sleeved in the two through holes respectively.

One end of the first pull rope 511 is fixed to the second permanent magnet 543, and one end of the second pull rope 512 is fixed to the first permanent magnet 541. The casing 551 surrounds the outside of the screw 330, and the screw 330 is coaxially fixed with two coils 561, wherein one coil 561 is fixed with the first electromagnet 542, and the other coil 561 is fixed with the second permanent magnet 543. The second permanent magnet 543 can attract or repel the second electromagnet 544, and the first permanent magnet 541 can attract or repel the first electromagnet 542. The middle part of the first pull rope 511 is fixed with the first slider 531, and the other end of the first pull rope 511 is connected with a connecting post 520. The middle part of the second pulling rope 512 is fixed with the second slider 532, the other end of the second pulling rope 512 is connected with the other connecting post 520, the surface of the first slider 531 near the first motor 340 is contacted with the lower end of the second cross bar 420, and the surface of the second slider 532 near the first motor 340 is contacted with the lower end of the first cross bar 410.

The present invention can realize the ascending, descending and tilting actions of the entire bed 100 by only one first motor 340, thereby saving the motor cost. The screw structure has a self-locking function, and the first cross rod 410 and the second cross rod 420 are provided with the limiting rings 220 as limiting, so that the connection is stable enough. The medical staff can realize the automatic ascending, descending and tilting actions of the bed body 100 by controlling the first electromagnet 542, the second electromagnet 544 and the first motor 340 only.

When the bed body 100 is required to be lifted without tilting, the first motor 340 can be electrified, and the first electromagnet 542 and the second electromagnet 544 can be continuously or intermittently electrified at the same time, because the rotation of the screw rod 330 lifts the connected body 200, and simultaneously, the rotation of the first motor 340 intermittently pulls the first pull rope 511 and the second pull rope 512, in other words, slowly pulls the movement of the first pull rope 511 and the second pull rope 512, so that the first cross rod 410 and the second cross rod 420 realize a larger cross state, and the bed body 100 is lifted at two ends, so that the bed body 100 is lifted at the middle part and two sides, and the bed body 100 is lifted without tilting.

When the bed body 100 is required to incline, referring to fig. 1 and 2, the first motor 340 can be energized, and one of the first electromagnet 542 and the second electromagnet 544 can be intermittently energized, so that one end of two sides of the bed body 100 is unchanged, and the other end is raised or lowered with the middle part.

In use, referring to fig. 1 and 3, when the bed 100 needs to be tilted or lowered for reset after rising, the first motor 340 is energized to rotate to a height far enough, the first electromagnet 542 and the second electromagnet 544 are powered off, and the first pull rope 511 and the second pull rope 512 are pulled to reset through the connecting column 520, so that the invention is restored to the position of fig. 1.

It should be noted that, the reason why the first electromagnet 542 and the second electromagnet 544 are intermittently energized is that the rotation of the first motor 340 is faster, and the helix angle of the screw 330 is generally relatively lower for self-locking, so that the screw 330 rotates for many turns, the upper rod body 310 also rises a small block, and at the same time, it is quite possible that the continuously energized first electromagnet 542 or second electromagnet 544 causes the wire coil 561 to pull the first pull rope 511 and/or the second pull rope 512, and drives the first slider 531 or the second slider 532 to travel a long distance, so that the lifting and tilting of the bed 100 are not stable, and thus, the intermittently energized first electromagnet 542 and the second electromagnet 544 can make the lifting speed of the end portion of the bed 100 be equal to the lifting speed of the middle portion or be combined with a stable and reasonable speed. Wherein, because the connection of the two magnets through attraction is relatively soft, even if the speed of the end part of the bed body 100 is not matched with the speed of the middle part, the two magnets can still be stably lifted and inclined through separation and re-attraction.

The cambered surface guide rail 430 can be fixed with the frame through a connecting frame which is obliquely arranged.

According to the present invention, the sides of the first and second crossbars 410 and 420 are provided with dovetail blocks, and the cambered surface guide rail 430 is provided with a dovetail groove, and the dovetail blocks are matched with the dovetail groove.

The present invention prevents the first and second crossbars 410 and 420 from moving longitudinally and falling off by the dovetail groove and the dovetail slider.

Preferably, the invention further comprises a limiting ring 220, the two limiting rings 220 are respectively surrounded at the top parts of the first cross rod 410 and the second cross rod 420, the limiting ring 220 is fixed with the lower surface of the connecting body 200, the lower surface of the connecting body 200 is provided with damping grooves 210 in the limiting ring 220, the damping grooves 210 are made of a plurality of arc grooves which are arranged side by side, the top parts of the first cross rod 410 and the second cross rod 420 are spherical, and the top parts of the first cross rod 410 and the second cross rod 420 are respectively overlapped with the damping grooves 210 at two sides of the lower surface of the connecting body 200.

The damping groove 210 can prevent the top parts of the first and second cross bars 410 and 420 from sliding, and the top parts of the first and second cross bars 410 and 420 can be randomly and transversely moved to have a lockable effect by mechanically limiting the top parts of the first and second cross bars 410 and 420 through the limiting ring 220.

Of course, a variant of the invention may also be: referring to fig. 6, the top parts of the first crossbar 410 and the second crossbar 420 are respectively provided with a first bayonet 211, two sides of the lower surface of the connecting body 200 are transversely provided with a first oblong hole 221, and the first bayonet 211 moves along the first oblong hole 221.
