Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses a medical bed.

Referring to fig. 1 and 2, a medical bed includes a bed body 1, a back plate 2, a support plate 3, and a driving assembly 4. The back plate 2 and the supporting plate 3 are flatly paved on the surface of the bed body 1, the two ends of the bed body 1 are respectively a bed head and a bed tail, the back plate 2 and the supporting plate 3 are sequentially distributed from the bed head to the bed tail, and the back surface of the back plate 2, far away from the bed head, forms a revolute pair with the bed body 1. The driving component 4 is positioned below the supporting plate 3 and can drive the back plate 2 to turn over. A rotating component 5 is connected between the back plate 2 and the supporting plate 3, and the whole or part of the supporting plate 3 can be driven to turn down synchronously when the back plate 2 turns up. Therefore, the patient can be changed from the lying posture to the sitting posture which is not easy to slide to the tailstock.

Referring to fig. 2 or fig. 3, the bed body 1 is a rectangular frame, a baffle 11 is fixed at each of the head and the tail of the bed body 1, the baffle 11 is perpendicular to the frame of the bed body 1, a guardrail 12 is fixed at each of two adjacent sides of the two baffles 11 fixed on the bed body 1, and a space for a patient to get out of the bed is left between the guardrail 12 and the baffles 11. Four universal wheels 13 are installed at the bottom of the bed body 1 and are used for transferring the medical bed. For convenience of description, the upper surface of the back plate 2 in a flat state is referred to as a front surface, and the corresponding lower surface is referred to as a back surface. Two supporting plates 22 are fixed on the back of the back plate 2, and one ends of the two supporting plates 22 close to the supporting plate 3 are rotatably connected with the bed body 1, so that the back plate 2 can rotate relative to the bed body 1. The inner wall of one end of the two support plates 22 near the rotation center is fixed with a rotation rod piece 21.

Referring to fig. 3 and 4, in the embodiment, the supporting plate 3 is partially turned down as an example, the supporting plate 3 includes a movable plate 32 and a fixed plate 33, the fixed plate 33 is laid on the bed body 1 near the bed tail, and the movable plate 32 is located between the fixed plate 33 and the back plate 2. One end of the movable plate 32 close to the fixed plate 33 forms a revolute pair with the bed body 1, and one end of the supporting plate 3 close to the back plate 2 is a free end.

A rotating assembly 5 is arranged between the back plate 2 and the supporting plate 3, the rotating assembly 5 comprises a movable plate 51, a sliding member 52 and an extending plate 53, the extending plate 53 is fixed at the free end of the movable plate 32, one end of the sliding member 52 is fixed at the extending plate 53, and the other end extends towards the side direction of the extending plate 53. The movable piece 51 is an arc-shaped long piece, and the movable piece 51 is provided with an arc-shaped movable groove 511 along the length direction thereof. Under the state that the back plate 2 and the supporting plate 3 are tiled, one end of the movable sheet 51 is fixed on the rotating rod piece 21, and the other end extends towards the bottom direction of the supporting plate 3 and the movable sheet 51 extends out of the back plate 2. The sliding piece 52 is inserted into the movable slot 511, and the end of the sliding piece 52 far away from the extending piece 53 is bolted with a nut to prevent the sliding piece 52 from being separated from the movable slot 511. When the operation posture changes, the back plate 2 turns upwards around the rotation center, the movable sheet 51 turns downwards, the upper inner wall of the movable groove 511 presses the sliding piece 52 to slide towards the direction of the movable groove 511 far away from the back plate 2, correspondingly, the free end of the supporting plate 3 turns downwards along with the sliding piece 52, and the patient is limited to slide towards the tail of the bed.

Referring to fig. 5, the driving assembly 4 includes a power source 43, a lead screw 46, and a driving lever 42. In this embodiment, the power source 43 is a hand lever, and the hand lever is connected to the lead screw 46 through a universal joint, and is used for driving the lead screw 46 to rotate and changing the power transmission direction of the lead screw 46. One end of the screw rod 46 close to the universal joint is connected with a sleeve 44 through an angular contact bearing, and the sleeve 44 is hinged at the bottom of the bed, so that one end of the screw rod 46 far away from the power source 43 swings around a hinged point of the sleeve 44 close to or far away from the bed body 1. The driving rod 42 is inserted into the screw rod 46 section of the screw rod 46 extending to the bed head, starting from the hinge point of the sleeve 44, and the driving rod 42 is in threaded connection with the screw rod 46. The end of the driving rod 42 far away from the screw rod 46 is hinged with a connecting piece 41, and the hinged point is closer to the bed head of the bed body 1 than the rotary connecting point of the back plate 2. The end of the link 41 remote from the drive rod 42 is fixed to the rotary rod member 21, and the rotary rod member 21 forms an obtuse angle with the back surface of the backboard 2 near the head of the bed. This allows the drive rod 42 to extend and contract along the length of the lead screw 46 while swinging toward and away from the bed 1 when the lead screw 46 is rotated. When the driving rod 42 moves towards the direction of the bed head, the driving rod 42 forces the connecting member 41 to drive the backboard 2 to rotate relative to the bed body 1.

Implementation principle of the embodiment: when the power source 43 drives the driving rod 42 to move toward the backboard 2, the end of the connecting member 41 connected to the backboard 2 is turned up to push the backboard 2 to turn up, and the backboard 2 can be used as a patient. The slide member 52 is moved obliquely downward by the movable plate 51, thereby turning the pallet 3 downward about its center of rotation. Patient's upper part of the body relies on backplate 2, and patient's buttock sinks, and the restriction patient health slides along 1 length direction of bed body, and the focus of health inclines to 2 directions of backplate, reduces that the patient has the risk of landing out of medical bed. When the power source 43 drives the driving rod 42 to move towards the direction far away from the back plate 2, the connecting piece 41 turns downwards, the back plate 2 tilts downwards, the movable piece 51 turns upwards along with the turning of the back plate 2 to force the supporting plate 3 to turn upwards, the back plate 2, the supporting plate 3 and the back plate 2 form a flat bed surface for a patient to lie down, and the patient can gradually change from a sitting posture to a lying posture.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
