Detailed Description
As shown in figures 1-9, referring to figures 1, 2 and 3, the medical sickbed of the invention comprises
A bed box 100, the bottom of which is fixed with the frame;

Wherein, a mattress, a bed sheet and/or a mattress can be arranged on the at least three row frames 200.
The elastic pull rope 201 passes through each skeleton row 200 and is fixed with the left side and the right side of the inside of the bed box 100, so that the skeleton row 200 is jacked up or pulled down to deform through the elasticity of the elastic pull rope, the jacking force or the pulling-down force is far greater than the gravity of a user, and the supporting force of the elastic pull rope 201 is far greater than the weight of the user. That is, the weight of the user is much smaller than the supporting force of the elastic cord 201, and the supporting force of the elastic cord 201 is much smaller than the force by which the user is jacked up or pulled down.
The elastic pull rope 201 may be made of rubber, latex, nitrile rubber, a first spring, etc.
The reason why the weight of the user is much smaller than the supporting force of the elastic cord 201 is that when the user lies on the rib frame 200, the plurality of rib frames 200 supported by the elastic cord 201 are still in a substantially horizontal state without generating excessive sinking.
Wherein, the skeleton 200 can be 3, 4, 5, 6, 7, 8, 9, 10 or more.
Referring to fig. 6, the skeleton frame 200 may be a plate-shaped body having a rectangular cross section or a roller-shaped body having a circular cross section.
As a further explanation of the present embodiment, referring to fig. 3, the at least three side frames 200 are connected to the side surface of the bed box 100 by at least five elastic pulling ropes 201 uniformly distributed along the length direction thereof.
The invention can ensure the supporting force of the elastic pull ropes 201 on the human body and the skeleton frame 200 through the plurality of elastic pull ropes 201, and at least two elastic pull ropes 201 can ensure that the skeleton frame 200 only moves up and down and cannot rotate.
Wherein, the number of the elastic pull ropes 201 can be: 2. 3, 4, 5, 6, 7, 8, 9, 10 or more.

According to the invention, the first connecting structure 312 and the spiral guide rail 306 can be reasonably matched in the above manner, so that the connection failure of the first pulley 322 and the spiral guide rail 306 is avoided, one of the skeleton frames 200 can be jacked up through the supporting block 323-shaped second connecting structure 313, and the skeleton frame 200 on the other side is relatively concave, so that the user can turn over conveniently.
The first connecting structure 312 further includes a bending rod 350, the lower end of the lifting rod 311 is fixed to the upper end of the bending rod 350, and the lower end of the bending rod 350 is provided with a shaft of the first pulley 322 through a bearing.
The first pulley 322 is preferably in a shape with a smaller outer diameter at the middle part and larger outer diameters at the two ends, so as to conveniently clamp the spiral guide rail 306, and the shape of the first pulley can be similar to that of a diabolo.
The spiral guide 306 may be a pointed guide disposed at the outer end of the spiral blade 307 and matching with the concave portion of the middle portion of the first pulley 322, so as to prevent the first pulley 322 from being separated from the spiral guide 306.
Wherein the spiral blade 307 may be integrally formed with the spiral guide 306.
When in use, when the first pulley 322 is overlapped with the middle part of the spiral guide rail 306, the supporting block 323 is overlapped with the lower surface of the middle skeleton row 200, and at least three skeleton rows 200 form a substantially plane state, or form an arc surface with a smaller concave radian; when the first pulley 322 is overlapped with both ends of the spiral guide 306, the supporting block 323 is overlapped with the lower surfaces of the skeleton frames 200 at both sides, and at least three skeleton frames 200 form a shape with one end being protruded and the other end being relatively less protruded to match the side surface stroke of the bed box 100 by a pit, so that the user can be assisted to turn over towards one side of the pit by the pit, and when the first pulley 322 moves back to the middle of the spiral guide 306, the user can reset by self gravity.
The supporting block 323 can be a round or square block, and the top of the block can be an arc or a hemisphere; of course, the supporting block 323 may also be a plate-shaped body with an arc-shaped top surface, and the length direction of the plate-shaped body is parallel to the length direction of the skeleton 200.
Wherein, the middle parts of the spiral guide rail 306 and the spiral blade 307 are opposite to the middle part of the bed box 100, that is, the middle parts of the spiral guide rail 306 and the spiral blade 307 are opposite to the framework 200 of the most middle one of the at least three frameworks 200.
For further explanation of this embodiment, referring to fig. 5, 6, 7 and 8, the middle portions of the spiral guide 306 and the spiral blade 307 are opposite to the middle portion of the bed box 100, and the outer diameters of the spiral guide 306 and the spiral blade 307 are gradually reduced from the middle to both ends;
the first connecting structure 312 includes a second pulley 332, the second pulley 332 is disposed in the spiral guide 306 and moves along the same, and a shaft of the second pulley 332 is mounted to a lower end of the lifting rod 311 through a bearing;

The second pulley 332 can freely move up and down along the spiral guide rail 306 through the cooperation of the second pulley 332 and the spiral guide rail 306, that is, when the second pulley 332 is in the middle of the spiral guide rail 306, the lifting rod 311 is higher, and when the second pulley 332 is at the two ends of the spiral guide rail 306, the lifting rod 311 is lower; the slide block 333 may cause the second guide rail 334 to locally bend concavely in different degrees along with the ascending and descending of the lifting rod 311, so as to cause one or more skeletons 200 fixed thereto to generate a concavity, thereby assisting the user in turning over.
Wherein the second rail 334 may be made of rubber or plastic or resin or nitrile rubber.
The second guide rails 334 are fixed to the lower surfaces or the middle portions of the at least three skeleton frames 200.
Referring to fig. 8, the spiral guide 306 wraps the upper and lower ends and one side surface of the second pulley 332, and the other side surface thereof is connected to a bearing at the lower portion of the lifting rod 311 through a shaft of the second pulley 332.
Referring to fig. 7, the second guide rail 334 includes an upper surface and two side surfaces of the slider 333, and a lower surface of the slider 333 protrudes from the second guide rail 334 and is fixedly connected to the upper end of the lifting rod 311.
The shaft of the second pulley 332 is mounted on the lower end of the bending rod 350 through a bearing, and the upper end of the bending rod 350 is fixed to the lower end of the lifting rod 311.
The present invention can make the axis of the lifting rod 311 always located in the same longitudinal straight line with the contact point of the first connecting structure 312 and the spiral guide 306 at the bottom of the lifting rod through the bending rod 350.
As a further explanation of this embodiment, the motor 301 can be held against rotation when de-energized.
The present invention locks the rotation of the spiral guide 306 by the motor 301 with a locked rotation angle, and prevents the spiral guide 306 from being rotated by the ascending or descending force of the elevating rod 311 acting on the spiral guide 306, thereby failing to lock the position of the elevating rod 311.
Of course, a modified structure of this embodiment may also be, referring to fig. 9, where the second sleeve 310 is connected to the first guide rail 308 through a locking mechanism 400, the locking mechanism 400 includes a first connecting rod 401, a second connecting rod 402, a third guide rail 403, an electromagnet 404, a first spring 405, a guide block 406, a locking pin 407, and a locking hole 408, one end of the first connecting rod 401 is fixed to the outer circumferential surface of the second sleeve 310, the other end of the first connecting rod 401 is fixed to one end of the second connecting rod 402, the middle of the second connecting rod 402 is fixed to one end of the third guide rail 403, the other end of the second connecting rod 402 is fixed to the electromagnet 404, a power module of the electromagnet 404 is connected to a user terminal through a communication module, the other end of the second connecting rod 402 is fixed to one end of the first spring 405, the other end of the first spring 405 is fixed to the guide block 406, the guide block 406 is fixed to one end of the locking pin 407, the guide block 406 is provided with a guide hole 409, the guide hole 409 is sleeved on the third guide rail 403, the first guide rail 308 is provided with a plurality of locking holes 408 along the length direction thereof, and the locking pin 407 can be locked in the locking holes 408.
According to the invention, by adopting the structure, when the electromagnet 404 is electrified, the clamping pin 407 is pulled out of the clamping hole 408, and when the lifting rod 311 transversely moves along the first guide rail 308 by the rotation of the motor 301, the movement of the lifting rod 311 can not be hindered. When the electromagnet 404 is de-energized, the elastic force of the first spring 405 can enable the guide block 406 to be inserted into the nearest card hole 408, so as to limit the transverse movement of the lifting rod 311, and thus maintain the stability of the up-and-down position of the skeleton 200 acted by the lifting rod 311.
One of the guide block 406 or the locking pin 407 is made of iron, and is preferably made of soft iron, i.e., memory-free iron, so that the locking pin 407 can be easily pulled out of the locking hole 408 by receiving the attractive force of the electromagnet 404 and overcoming the elastic force of the first spring 405.
A power module of the electromagnet 404 may be fixed to the second connecting rod 402, and the power module may be a battery or connected to a power source through a wire.
