Description

TECHNICAL FIELD

[0001] The utility model relates to nursing bed technical field, concretely relates to a supplementary bedstead for nursing bed. BACKGROUND

[0002] In modern medical care, patients who are in bed for a long time are difficult to turn over by themselves due to physical weakness or disease. The traditional nursing method often needs nursing staff to manually assist the patient to turn over, which not only increases the workload of the nursing staff, but also has the risk of difficult operation, causing discomfort or injury to the patient. In addition, long-term bed rest in the same position may also cause the patient to develop bedsores, poor blood circulation and other complications, which seriously affects the patient's recovery process.

[0003] There are some nursing bed products on the market at present, such as electric nursing beds and manual nursing beds. These products provide a turning function to some extent, but often have problems such as complex structure, inconvenient operation, unstable structure, etc. Referring to the Chinese invention patent application No. 202410611055.X, a kind of rehabilitation nursing bed convenient for turning over is disclosed. The nursing bed is provided with a plurality of angle adjusting mechanisms at the bottom of the bed plate, and each angle adjusting mechanism is correspondingly provided with a turning plate. In the angle adjusting mechanism, one end of the turning plate is fixedly connected with a driven shaft, and the driven shaft is fixedly connected with a driven gear. The first moving assembly drives the driven gear to mesh and move on the moving gear plate, thereby driving the turning plate to reverse upward and supporting the patient's reversed body.

[0004] However, in the above structure, the support force of the turning plate on the patient is provided by the torque generated by the driven gear meshing on the moving gear plate. Since the length L1 of the support end from the driven shaft is much greater than the length L2 of the driven gear radius, according to the lever principle formula: F1xL1=F2xL2, if the turning plate is to support the patient, the pushing force F2 generated by the driven gear meshing on the moving gear plate must be much greater than the downward force F1 of the patient's body weight parameter. According to the torque formula: T=Fr, the greater the pushing force, the greater the torque generated. Under such high-torque working conditions, the structure of the turning plate, driven shaft, driven gear and moving gear plate requires higher requirements, or specific materials are selected for processing, otherwise the structure may be unstable. This greatly increases the processing cost and production cost, resulting in high bed frame prices and increased maintenance costs. UTILITY MODEL CONTENTS

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a supplementary bedstead for nursing bed.

[0006] The technical scheme adopted by the utility model to solve its technical problems is:

[0007] An assisted turning bed frame for use on a nursing bed includes a support frame, a bed board mounted on the upper part of the support frame, and a drive device mounted on the lower part of the support frame. The drive end of the drive device is connected to the bed board to drive the bed board to move. The bed board includes a turning frame for assisting turning and a flipping plate for assisting getting up. The turning frame is fixedly mounted at the rear of the support frame, and the flipping plate is located at the head of the support frame and one end is hinged to the turning frame. The drive device includes a first drive assembly connecting the turning frame and a second drive assembly connecting the flipping plate. The turning frame includes a support frame fixedly connected to the support frame and two sets of support plates movably arranged inside the support frame. The two sets of support plates are arranged opposite each other and have multiple support grids extending horizontally in the left-right direction on their inner sides. The oppositely arranged support grids alternately intersect to form a support surface. The turning frame also includes a rotating shaft arranged horizontally in the middle of the support frame in the front-back direction. The rotating shaft passes through all the support grids on the two sets of support frames to form support. The extended ends of the two sets of support grids are provided with linkage rods, and the linkage rods are connected to the first drive assembly.

[0008] Furthermore, the first drive assembly includes two sets of first fixed beams that span across the lower part of the support frame and two sets of first telescopic rods that are respectively mounted opposite each other on the first fixed beams. The fixed end of the first telescopic rod is hinged to the first fixed beam, and the telescopic end of the first telescopic rod is hinged to the linkage rod. The bottom of the linkage rod is provided with a hinge seat for hinged to the first telescopic rod. Under normal conditions, the first telescopic rod extends out and is supported under the support plate. When the first telescopic rod retracts, it causes the support plate to flip and tilt up.

[0009] In this utility model, the bed board is provided with multiple sets of turning frames, which are arranged and connected in sequence along the front-to-back direction. The top of the support frame is provided with multiple connecting seats for supporting the turning frames, which are supported on the support frame of the multiple sets of turning frames.

[0010] Furthermore, the multiple sets of turning frames are interconnected and move synchronously through linkage rods.

[0011] Furthermore, a first drive component is respectively provided below each of the multiple sets of turning frames.

[0012] In this utility model, the second driving assembly includes a second fixed beam spanning across and connected to the lower part of the support frame, a second telescopic rod with its fixed end hinged to the second fixed beam, a flipping arm hinged to the telescopic end of the second telescopic rod, and a support base fixed to the support frame. The flipping arm includes a support part rotatably connected to the support base, an active arm connected to the second telescopic rod, and a driven arm abutting against the lower part of the flipping plate. Normally, the second telescopic rod is in an extended state. When the second telescopic rod retracts, it drives the active arm to flip downward. The active arm uses the support part as a fulcrum to tilt the driven arm upward and lift the flipping plate upward.

[0013] Furthermore, the driven arm is provided with a roller at its end, and the bottom of the tilting plate is provided with a reinforcing plate for the roller to roll, with the roller pressing against the reinforcing plate.

[0014] This utility model has the following advantages and beneficial effects:

[0015] The turning frame consists of a support frame fixed to a support frame and two sets of opposing support plates set inside the support frame. The opposing support plates are connected to each other alternately by support grids. A rotating shaft runs horizontally through the support grid in the middle of the support frame. The extended ends of the support grids are connected by linkage rods, so that the entire support plate and support grids form a lever with the rotating shaft as the fulcrum. The first drive mechanism drives the linkage rod to rotate downward and at the same time drives the support plate to tilt upward, thereby supporting the patient to turn over. In this structure, the distance between the linkage rod and the support plate and the fulcrum is close, so there will not be a large torque difference. Therefore, while ensuring structural stability, it can also reduce the requirements for materials, thereby reducing production and processing costs, and thus reducing the maintenance cost and price of the bed frame.

[0024] like Figs. 1 to 4As shown, this embodiment discloses an auxiliary turning bed frame for use on a nursing bed, including a support frame 1, a bed board 2 installed on the upper part of the support frame 1, and a drive device 3 installed on the lower part of the support frame 1. The drive end of the drive device 3 is connected to the bed board 2 to drive the bed board 2 to move. The bed board 2 includes a turning frame 21 for assisting turning and a flipping plate 22 for assisting getting up. The turning frame 21 is fixedly installed at the tail of the support frame 1, and the flipping plate 22 is located at the head of the support frame 1 and one end is hinged to the turning frame 21. The drive device 3 includes a first drive assembly 31 connecting the turning frame 21 and a second drive assembly 32 connecting the flipping plate 22. The turning frame 21 includes a support frame 211 fixedly connected to the support frame 1 and two sets of support plates 212 movably arranged inside the support frame 211. The two sets of support plates 212 are arranged opposite to each other and have multiple support grids 213 extending horizontally in the left and right direction on their inner sides. The supporting grids 213 are alternately interwoven to form a supporting surface. The turning frame 21 also includes a rotating shaft 214 horizontally arranged in the middle of the supporting frame 211 along the front-back direction. The rotating shaft 214 passes through all the supporting grids 213 on the two sets of supporting frames 211 to form support. The extended ends of the two sets of supporting grids 213 are provided with linkage rods 215. In order to avoid interference, the linkage rods 215 are arranged on the lower side of the ends of the supporting grids 213. The supporting grids 213 arranged opposite to each other can also play a role in supporting each other through the linkage rods 215. Specifically, the linkage rods 215 are connected to the first drive assembly 31. The first drive assembly 31 drives one end of the supporting grid 213 to rotate downward around the rotating shaft 214 through the linkage rods 215, and tilts the supporting plate 212 at the other end with the rotating shaft 214 as the fulcrum. The tilted supporting plate 212 can support one side of the patient to assist the patient in turning over.

[0025] Furthermore, since the support frame 211 has two sets of opposing support plates 212, it is necessary to drive the two sets of support plates 212 to tilt up respectively. The first drive assembly 31 includes two sets of first fixed beams 311 that span across the lower part of the support frame 1 and two sets of first telescopic rods 312 that are respectively mounted opposite each other on the first fixed beams 311. The first telescopic rods 312 can be electric push rods. The fixed end of the first telescopic rods 312 is hinged to the first fixed beams 311, and the telescopic end of the first telescopic rods 312 is hinged to the linkage rod 215. Specifically, the bottom of the linkage rod 215 is provided with a hinge seat 313 for hinged to the first telescopic rods 312. Under normal conditions, the first telescopic rods 312 extend and support the support plates 212 below to prevent the support plates 212 from rotating. When the patient needs to be assisted to turn over, by controlling the first telescopic rods 312 on one side to retract, the support plates 212 are driven to flip up and provide support force.

[0026] In this embodiment, in order to provide sufficient support strength for the bed board 2, multiple sets of turning frames 21 are provided on the bed board 2. The multiple sets of turning frames 21 are arranged and connected in sequence along the front-to-back direction. The top of the support frame 1 is provided with multiple vertically extending connecting seats 11 for supporting the turning frames 21. Specifically, the tops of the multiple connecting seats 11 are supported on the support frame 211 of the multiple sets of turning frames 21. The bed board 2 is formed by the multiple sets of turning frames 21 arranged in sequence and supported by the connecting seats 11, which makes the structural stability of the bed board 2 better, provides greater turning force, and facilitates the patient's turning.

[0027] Furthermore, multiple sets of turning frames 21 can be connected to each other through linkage rods 215 to achieve synchronous action, or a first drive component 31 can be set at the lower part of each corresponding turning frame 21 for individual drive to ensure driving force. Of course, each set of first drive components 31 can also be linked to each other to achieve synchronous action.

[0028] In this embodiment, the second drive assembly 32 includes a second fixed beam 321 spanning across the lower part of the support frame 1, a second telescopic rod 322 with its fixed end hinged to the second fixed beam 321, a flipping arm 323 hinged to the telescopic end of the second telescopic rod 322, and a support seat 324 fixed to the support frame 1. Specifically, the flipping arm 323 includes a support part 325 rotatably connected to the support seat 324, an active arm 326 connected to the second telescopic rod 322, and a driven arm 327 abutting against the lower part of the flipping plate 22. Normally, the second telescopic rod 322 is in an extended state, and the movable end of the flipping plate 22 abuts against the support frame 1 and is in a horizontal state. When the patient needs to get up, by controlling the second telescopic rod 322 to retract, it drives the active arm 326 to flip downward, while the active arm 326 tilts the driven arm 327 upward with the support part 325 as the fulcrum, thereby lifting and flipping the flipping plate 22 upward, thus assisting the patient to get up.

[0029] Furthermore, the driven arm 327 is provided with a roller 328 at its end, and the bottom of the tilting plate 22 is also provided with a reinforcing plate 221 for the roller 328 to roll. When the driven arm 327 tilts upward, the roller 328 abuts against the reinforcing plate 221, thereby reducing wear.

[0030] In this embodiment, guardrails 4 are connected to both sides of the support frame 1, and pulleys 5 are provided at the bottom of the support frame 1.

[0031] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
