Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a nursing bed frame with a limiting structure. Background Technology

[0002] The nursing bed frame is the basic structural component of a nursing bed. It not only supports the weight of the mattress and the user but also integrates various functional designs to meet the needs of patient care. Nursing bed frames are widely used in hospital wards, rehabilitation centers, nursing homes, and other facilities to support patients requiring special care. They are particularly suitable for patients with limited mobility, those who are bedridden for extended periods, or those who require regular care, helping to improve their quality of life and reduce the workload of caregivers.

[0003] Traditional nursing bed frames mostly use manually pulled guardrails on both sides as the main protective structure. These guardrails are usually relatively simple in structure and can provide a certain degree of protection against accidental falls when patients get up, turn over, or perform daily activities. However, when the guardrails are subjected to significant external impact, such as when a patient leans against them with great force, they are prone to shaking, deformation, or even loosening, posing certain safety hazards.

[0004] Therefore, there is a particular need for a nursing bed frame with a limiting structure to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional nursing bed frames, which are prone to shaking, deformation or loosening when subjected to large external impacts, posing safety hazards, this utility model provides a nursing bed frame with a limiting structure.

[0006] This utility model is achieved through the following technical means: a nursing bed frame with a limiting structure, including a frame, support columns, a bottom connecting plate, a headboard, and a footboard. A support column is fixed to multiple corners at the bottom of the frame. A bottom connecting plate is fixed between one end of two horizontally aligned support columns. The headboard is fixed to one side of the top of the frame, and the footboard is fixed to the other side of the top of the frame. It also includes a protective plate, sliders, a lifting switch, a guide rod, a motor, a worm gear, a worm wheel, and a lead screw. Each support column has a groove, and a slider is slidably disposed inside each groove. A protective plate is fixed between two longitudinally aligned sliders. A guide rod is fixed inside each of the two grooves. The bed has two guide rods that slide through two sliders and engage with them. Two lead screws are rotatably mounted inside the other two slides, and these lead screws also threadedly engage with the other two sliders. A motor is mounted on one side of each of the other two support columns. A lifting switch is also located on one side of each of the two support columns. Two more lifting switches are arranged side-by-side on one side of the headstock. All lifting switches are electrically connected to two motors. The output shaft of each motor extends into the corresponding support column and is fixedly connected to a worm gear via a coupling. The worm gear is located inside the corresponding support column. A worm wheel is fixedly connected to one end of each lead screw. The number of worm wheels matches the number of worm gears, and they mesh one-to-one.

[0007] Furthermore, it also includes protective rods and hinge rods. Each protective plate has multiple hinge rods arranged in a longitudinal straight line at its top. On the same side, a protective rod is rotatably arranged between one end of the multiple hinge rods. The two protective rods are also distributed in a mirror symmetrical manner on both sides of the frame.

[0008] Furthermore, it also includes a table and a pivot seat. The two pivot seats are fixed side by side to the upper side of the bed end frame. The table is rotatably positioned between the two pivot seats and is in a vertical position against one side of the bed end frame.

[0009] Furthermore, it also includes protective covers, with two protective covers arranged side by side and rotating on one side of the headboard, each covering one of the two lifting switches on the headboard.

[0010] Furthermore, a groove is provided on each of the lower sides of the tabletop.

[0011] Furthermore, each guard rod has multiple grooves arranged sequentially along its length on both sides.

[0012] Beneficial effects: 1. The limiting assembly, composed of a protective plate, slider, lifting switch, guide rod, motor, worm gear, worm wheel and lead screw, can build a stable limiting structure on the left and right sides of the nursing bed frame. Even when the protective plate is subjected to a large external impact, thanks to the stability of the threaded fit between the lead screw and the slider and the precise guiding effect of the guide rod, it is not easy to shake, deform or even loosen, which significantly improves the safety performance of the nursing bed frame and provides more reliable protection for patients.

[0013] 2. Through the cooperation of the protective rod and the hinge rod, an additional protective structure is formed at the top of the protective plate, which together with the protective plate constitutes double protection and enhances the protective capability of the nursing bed.

Detailed Implementation

[0023] Example: A nursing bed frame with a limiting structure, such as Figures 1-8As shown, the bed includes a frame 1, support columns 2, a bottom connecting plate 3, a headboard 4, and a footboard 5. A support column 2 is welded to each of the four corners at the bottom of the frame 1. A bottom connecting plate 3 is welded between the lower ends of two horizontally aligned support columns 2. The headboard 4 is welded to the rear top of the frame 1, and the footboard 5, which has the same structure as the headboard 4, is welded to the front top of the frame 1. The bed also includes a protective plate 6, a slider 61, a lifting switch 8, a protective cover 81, a guide rod 11, a motor 12, a worm gear 13, a worm wheel 14, and a lead screw 15. Each support column 2 has a groove 10, and each groove 10 contains a sliding... A sliding block 61 is provided, and a protective plate 6 is welded between two longitudinally aligned sliding blocks 61. The two protective plates 6 are mirror-symmetrically distributed on the left and right sides of the frame 1, and the inner side of each protective plate 6 is kept on the same vertical plane as the corresponding outer side of the frame 1, headboard 4, and footboard 5, ensuring a tight fit between the protective plate 6 and the frame 1, headboard 4, and footboard 5 when raised. A guide rod 11 is welded inside each of the two rear sliding grooves 10, and the two guide rods 11 pass through the two rear sliding blocks 61 and slide with them. A lead screw 15 is rotatably installed inside each of the two front sliding grooves 10. The lead screw 15 passes through the two front sliders 61 and is threaded to them. A motor 12 is bolted to the lower front end of each of the two front support columns 2. A lifting switch 8 is installed on the upper front end of each of the two front support columns 2. Two more lifting switches 8 are arranged side-by-side on the front side of the headboard 4. All four lifting switches 8 are electrically connected to the two motors 12. Two protective covers 81 are rotatably mounted side-by-side on the front side of the headboard 4, covering the two lifting switches 8 on the headboard 4 to prevent patients from accidentally activating the two lifting switches 8 on the headboard 4 while on the nursing bed. The output shaft of each motor 12 extends into the corresponding support column 2. A worm gear 13 is welded to the corresponding support column 2 via a coupling. The worm gear 13 is located inside the corresponding support column 2. A worm wheel 14 is welded to the lower end of each lead screw 15. The number of worm wheels 14 is the same as the number of worm gears 13, and they mesh one-to-one. Each lifting switch 8 is equipped with an up arrow and a down arrow. The up arrow corresponds to the lifting operation. When the arrow button is pressed, the relevant component will perform the lifting action. The down arrow represents the lowering command. After pressing the arrow button, the relevant component will perform the lowering operation. This intuitive label design makes it easy for medical staff and patients to quickly understand and operate the lifting function and the lifting command.

[0024] like Figures 1-4 , Figure 7 and Figure 8As shown, it also includes protective rods 7 and hinge rods 71. Each protective plate 6 has four hinge rods 71 ​​arranged in a longitudinal straight line at its top. A protective rod 7 is rotatably arranged between the upper ends of the four hinge rods 71 ​​on the same side. The two protective rods 7 are also distributed in a mirror symmetrical manner on the left and right sides of the frame 1. Each protective rod 7 has three grooves arranged in sequence along its length on its left and right sides, which facilitates gripping the protective rod 7.

[0025] like Figures 1-4 and Figure 8 As shown, it also includes a tabletop 9 and a pivot seat 91. The two pivot seats 91 are welded side by side to the upper front side of the bed end frame 5. The tabletop 9 is rotatably set between the two pivot seats 91 and is in a vertical state to fit against the front side of the bed end frame 5. The lower front and rear sides of the tabletop 9 each have a groove, which makes it easy to grip the tabletop 9.

[0026] Before the nursing bed frame is put into use, the mattress is first laid on frame 1. After the basic installation is completed, it can be used normally.

[0027] When a patient is lying in bed, if the protective panel 6 needs to be raised to prevent accidental falls, medical staff can press the up arrow button on any of the lifting switches 8. This signal is transmitted to the control circuit, triggering the motor 12 to start. The output shaft of the motor 12 drives the worm gear 13 to rotate clockwise. The worm gear 13 and worm wheel 14 engage in forward transmission, thereby driving the lead screw 15 to rotate counterclockwise. Driven by the lead screw 15, the front slider 61 slides upwards along the direction of the lead screw 15, while the rear slider 61 slides smoothly along the guide rod 11, providing auxiliary support. The guide function is that as the front and rear sliders 61 rise, the protective plate 6 fixed to them rises synchronously until the sliders 61 reach the top of the slide groove 10 and contact the limit point. At this time, the control system automatically cuts off the power to the motor 12, and the protective plate 6 stops rising, completing the automatic limit process and ensuring safe and reliable operation. Then, the protective rod 7 is manually pulled upward to unfold the hinged rod 71 structure, so that it and the protective rod 7 together form a stable support structure, forming a continuous guardrail at the top of the protective plate 6, providing double safety protection for the patient and effectively preventing falls.

[0028] When the protective plate 6 needs to be lowered, medical staff press the down arrow button on any of the lifting switches 8. After the command signal is transmitted to the control circuit, the motor 12 is triggered to start again. The output shaft of the motor 12 drives the worm gear 13 to rotate counterclockwise. The worm gear 13 and the worm wheel 14 achieve reverse meshing transmission, thereby driving the lead screw 15 to rotate clockwise. Under the drive of the lead screw 15, the front slider 61 slides down along the direction of the lead screw 15. As the front and rear sliders 61 descend, the protective plate 6 fixed to them descends synchronously until the slider 61 reaches the bottom of the slide groove 10 and contacts the limit point. At this time, the control system automatically cuts off the power to the motor 12, and the protective plate 6 is completely restored to its original position. Then, the protective rod 7 is folded down and the hinge rod 71 is retracted, returning to the storage state without affecting the patient's getting in and out of bed or performing daily nursing operations.

[0029] When a patient needs to eat or temporarily place items, the table 9 can be rotated 240 degrees clockwise from the front of the bed end frame 5, so that it flips from a vertically attached state to a horizontally unfolded state and is stably supported by the top of the bed end frame 5. At this time, the patient can move their body close to the area of ​​the table 9 and start eating or using related items, which improves the functionality and ease of use of the nursing bed.
