[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 The utility model provides a technical solution: a multifunctional medical bed bracket, including a bed 1, a bracket 2 is fixedly arranged at the four corners of the lower end surface of the bed 1, a first bed board 3 is fixedly arranged on one side of the upper end of the bed 1, a second bed board 4 is movably arranged on the upper end of the bed 1 on one side of the first bed board 3 through a rotating shaft, a rotating mechanism for helping the patient to turn is provided on one side of the bed 1, the rotating mechanism includes a bottom plate 5, a rotating platform 6, a guardrail 7, and a walking aid 8, a bottom plate 5 is provided on one side of the bracket 2, a rotating platform 6 is movably arranged on one side of the upper end of the bottom plate 5 through a rotating shaft, guardrails 7 are fixedly arranged on both sides of the upper end of the rotating platform 6, and a walking aid 8 is provided between the guardrails 7 on the upper end of the bottom plate 5.
[0022] A transmission mechanism for driving the rotating table 6 to rotate is arranged between the bottom plate 5 and the rotating table 6, and the transmission mechanism includes a worm wheel 9, a worm 10, and a motor 11. A worm wheel 9 is fixedly arranged on the outer side of the rotating shaft where the rotating table 6 is located, and a worm 10 is arranged on the upper end of the bottom plate 5 on one side of the worm wheel 9. A motor 11 is fixedly arranged on the upper end of the bottom plate 5 on one side of the worm 10. The rotating table 6 can be driven to rotate through the transmission mechanism, so that the patient's buttocks can be aligned with the bed 1, so that the patient can sit on the bed, and then use his hands to help get on the bed, which is convenient for self-care;
[0023] The output shaft end of the motor 11 is connected to the worm 10 through a coupling, and the motor 11 drives the worm 10 to rotate, thereby driving the worm wheel 9 to rotate, so that the rotating table 6 can rotate. When the motor 11 and the worm 10 do not rotate, the worm wheel 9 and the rotating table 6 cannot rotate.
[0024] The worm wheel 9 and the worm 10 mesh with each other, and the helix angle of the worm 10 is smaller than the equivalent friction angle between the meshing teeth of the worm 10 and the worm wheel 9, so that the worm wheel 9 and the worm 10 can form a self-locking, so that the rotating table 6 cannot rotate when the motor 11 does not rotate, which can improve the safety of the patient getting on and off the rotating table 6;
[0025] A locking screw 12 is fixedly provided between the bottom plate 5 and the bracket 2, and the bottom plate 5 and the bracket 2 are fixed by the locking screw 12, so that when the rotating mechanism of the device is not needed, the rotating mechanism can be disassembled, and the bed 1 can be used like an ordinary bed 1;
[0026] An extension plate 13 is fixedly provided on the surface of the bracket 2 on one side, and an electric push rod 14 is movably provided on the upper end of the extension plate 13 through a rotating shaft. The movable end of the electric push rod 14 is movably connected to the second bed board 4 through the rotating shaft. The second bed board 4 can be driven to adjust the pitch angle by extending and shortening the electric push rod 14.
[0027] An inclined plate 15 is provided on one side of the surface of the rotating platform 6 , and the wheels of the walking aid 8 can pass through the inclined plate 15 , so that the user can move to the upper end of the rotating platform 6 conveniently.
[0028] Working principle: When using the device, the bed 1 is used in the same manner as the beds 1 of the prior art. The fences on both sides of the bed 1 are liftable guardrails 7, so that when ordinary patients get on and off the bed 1, the fences can be lowered for use; and the device also has the pitch angle adjustment function of the traditional bed 1. By contracting the electric push rod 14, the second bed board 4 can be pushed to rotate, so that the inclination angle of the second bed board 4 can be adjusted;
[0029] However, when the conventional hospital bed 1 is used for patients with leg discomfort who use the walking aid 8 for rehabilitation training, when the patient uses the walking aid 8 to move to the bedside and wants to get into bed, if the patient walks from the front, there will be a walking aid 8 between him and the bed 1, which makes it inconvenient to get into bed; if the patient walks from the side, he wants to sit on the bed and then use his arms to help get into bed, which involves the problem of turning around by himself, which is difficult for patients with leg discomfort and has certain risks. If the patient walks backwards to the bedside, although it is convenient to sit on the bed and then get into bed, the overall risk is high;
[0030] When the device is used for patients with leg discomfort who use the walking aid 8 for rehabilitation training, the patient can walk to the upper end of the rotating table 6 through the walking aid 8 to form a Figure 1 The motor 11 then drives the worm 10 to rotate, thereby driving the worm wheel 9 to rotate, so that the rotating table 6 can be driven by the worm wheel 9 to rotate slowly, so that the device can form Figure 2 In the state shown, the patient's buttocks are close to the bedside, and the rotating platform 6 raises the patient as a whole. At this time, the patient's buttocks are close to the bedside and at a higher position, and then the patient sits on the bed 1. Then, the patient can use his arms to get on the bed by himself. In this way, when the device is used, a rotating mechanism is added to the side of the traditional bed 1, so that patients with leg discomfort who use the walking aid 8 for rehabilitation training can get on the bed conveniently and take care of themselves.
[0031] When the device is in use, the worm wheel 9 and the worm 10 can form a self-locking function, so that the rotating platform 6 cannot rotate when the motor 11 does not rotate, thereby improving the safety of the patient getting on and off the rotating platform 6. At the same time, the base plate 5 and the bracket 2 are fixed by the locking screws 12, so that when the rotating mechanism of the device is not needed, the rotating mechanism can be disassembled, and the bed 1 can be used like an ordinary bed 1.
