Description

Technical Field

[0001] This invention relates to the medical field, specifically to a medical nursing bed. Background Technology

[0002] Nursing beds are medical beds designed specifically for bedridden patients and are widely used in hospital wards, rehabilitation institutions, and home care settings. Generally, the bed frame can be adjusted to different body positions and is equipped with protective railings on both sides. The railings of nursing beds are also equipped with detachable tabletops, which are commonly used auxiliary accessories in clinical nursing work. They are attached to the movable railings on both sides of the bed frame through the slot structure of the side blocks, without the need for additional support components.

[0003] Therefore, it can be seen that the existing medical nursing beds' detachable tabletops are simply attached to the movable guardrails via slots. During clinical use, when medical staff are tidying up the bed unit or family members are accompanying patients, they may inadvertently release the guardrail's locking mechanism before the tabletop is folded back, causing the guardrail to fold and collapse unexpectedly. This can lead to the tabletop and the food, medicine, and nursing equipment on it tipping over, interfering with normal nursing operations and potentially causing damage to items or injuries to the patient. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a medical nursing bed that addresses the above-mentioned deficiencies in the prior art. After the table is installed, the pin passes through the movable rod limiting hole and inserts into the limiting rod limiting groove to restrict the axial displacement of the limiting rod, thereby preventing accidental button presses that could cause the guardrail to collapse or the table to tip over, thus improving safety and effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A medical nursing bed includes a nursing bed frame with guardrails on both sides. Each guardrail includes a fixed rod and a movable rod. The fixed rod is fixedly installed on one side of the nursing bed frame. The movable rod is movably installed above the fixed rod via multiple surrounding rods. A limit rod is slidably connected to the movable rod along its axial direction. A buckle box is fixedly installed at the lower end of the movable rod near one of the surrounding rods. A button is movably inserted into the buckle box. A buckle seat is fixedly installed on the side of the surrounding rod adjacent to the buckle box. A table is provided between two movable rods. A latching block is fixedly installed on both sides of the table. A slot is opened at the lower end of the latching block, and the slot is detachably engaged with the movable rod at the corresponding position.

[0007] As a further preferred embodiment of the present invention, a plurality of first bearing seats are fixedly installed at equal intervals along the axial direction at the upper end of the fixed rod, and a number of second bearing seats, which are the same as the number of first bearing seats, are fixedly installed at equal intervals along the axial direction at the lower end of the movable rod. The two ends of the surrounding rod are respectively hinged in the first bearing seats and the second bearing seats at corresponding positions, thereby realizing the folding and unfolding action of the movable rod relative to the fixed rod.

[0008] As a further preferred embodiment of the present invention, the upper end of the movable rod is provided with a plurality of limiting holes along its axial direction, and the inner bottom surface of the movable rod is integrally formed with two guide rails symmetrically along its axial direction. The longitudinal cross section of the guide rails is inverted L-shaped. The two guide rails provide an axial sliding guide path for the limiting rod and constrain the vertical displacement of the limiting rod within the movable rod.

[0009] As a further preferred embodiment of the present invention, the lower end of the limiting rod is provided with a sliding groove adapted to the guide rail and slides in cooperation with the guide rail. The lower end face of the limiting rod is provided with a slope groove, which is located directly above the buckle box. The upper end of the limiting rod is provided with a number of limiting grooves along its axial direction that are consistent with the number of limiting holes, and each limiting groove is coaxially arranged with the corresponding limiting hole. The end of the limiting rod away from the slope groove is provided with a spring groove, and a first compression spring is inserted into the spring groove. One end of the first compression spring is inserted into the inner side wall of the movable rod.

[0010] As a further preferred embodiment of the present invention, the upper end of the buckle is provided with a buckle groove.

[0011] As a further preferred embodiment of the present invention, a top rod is fixedly installed on the upper end of the button. The upper end of the top rod passes through the movable rod and abuts against the slope groove. A second compression spring is also fitted on the top rod located between the movable rod and the button. The second compression spring provides a thrust for the button to return to its downward position. A latch is fixedly installed on the lower end face of the button. The lower end of the latch is inserted into the latch groove. Thus, the button, latch, and latch seat are connected and limited. With the cooperation of the latch box, the movement of the surrounding rods of the adjacent latch box and the movable rod is limited, thereby ensuring that the movable rod is raised and unfolded by multiple surrounding rods.

[0012] As a further preferred embodiment of the present invention, a plurality of pins are fixedly installed on the inner top surface of the slot. The lower end of each pin passes through the corresponding limiting hole and is inserted into the corresponding limiting groove. This enables the tabletop to be installed between the two movable rods, and the pins cooperate with the movable rods to limit the axial movement of the limiting rods. This prevents the top rod from moving upward after the slope groove abuts against the upper end of the top rod, thereby preventing accidental operation of the button and preventing the tabletop from tipping over when the movable rod is retracted during use.

[0013] As a further preferred embodiment of the present invention, a guide sleeve is also provided inside the buckle box, the button is slidably inserted into the guide sleeve, the upper end of the button is provided with a top rod, the upper end of the top rod passes into the movable rod and abuts against the limiting rod, the lower end of the button is provided with a buckle rod, the lower end of the buckle rod passes out of the buckle box and is detachably inserted into the buckle groove of the buckle seat, and an elastic element for forcing the button to reset is provided between the button and the buckle box.

[0014] As a further preferred embodiment of the present invention, the lower end surface of the tabletop is provided with an anti-slip pad layer, which abuts against the upper end surface of the movable rod when the tabletop is engaged with the movable rod.

[0015] As a further preferred embodiment of the present invention, a buffer sleeve is provided on the railing, the buffer sleeve being located between the fixed rod and the movable rod. When the railing is folded, the buffer sleeve elastically abuts against the adjacent railing and the fixed rod respectively.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, after the guardrail is unfolded, the buttons and buckles inside the buckle box can be inserted into the buckle slots of the buckle seat to stably maintain the unfolded state. A detachable table can be installed between the two movable rods. The table is fixed by the slots of the side blocks. After the table is installed, the pin in the slot will pass through the limiting hole of the movable rod and insert into the limiting groove of the limiting rod to restrict the axial movement of the limiting rod. This prevents the guardrail from collapsing or the table from tipping over due to accidental pressing of the button when using the table, thus improving the safety and structural reliability.

[0018] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0025] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0026] This invention proposes a medical nursing bed, including a nursing bed body 1. Guardrails 2 are provided on both sides of the nursing bed body 1. Each guardrail 2 includes a fixed rod 3 and a movable rod 4. The fixed rod 3 is fixedly installed on one side of the nursing bed body 1. The movable rod 4 is movably installed above the fixed rod 3 via multiple surrounding rods 5. A limit rod 6 is slidably connected within the movable rod 4 along its axial direction. A buckle box 7 is fixedly installed at the lower end of the movable rod 4 near one of the surrounding rods 5. A button 8 is movably inserted into the buckle box 7. A buckle seat 9 is fixedly installed on one side of the surrounding rod 5 adjacent to the buckle box 7. A tabletop 10 is provided between two movable rods 4. A support block 11 is fixedly installed on both sides of the tabletop 10. A slot 12 is provided at the lower end of the support block 11, which is detachably engaged with the corresponding movable rod 4.

[0027] Specifically, such as Figures 2-3 As shown, multiple first bearing seats 13 are fixedly installed at equal intervals along the axial direction on the upper end of the fixed rod 3, and the number of second bearing seats 14, which are the same as the number of first bearing seats 13, are fixedly installed at equal intervals along the axial direction on the lower end of the movable rod 4. The two ends of the surrounding rod 5 are respectively hinged to the corresponding first bearing seats 13 and second bearing seats 14, thus forming a parallel folding and unfolding mechanism. When the guardrail 2 is unfolded from the folded state, the operator pulls the movable rod 4 upwards. The movable rod 4 rotates around the second bearing seats 14 through the multiple surrounding rods 5, and the lower end of the surrounding rod 5 rotates around the corresponding first bearing seat 13, thereby gradually raising it. Since the upper end of the buckle 9 has a buckle groove 22, the lower end of the button 8 is fixed... A latch 23 is installed, with its lower end inserted into a latch groove 22. The latch 23 and the latch groove 22 can lock the relative position between the movable rod 4 and the guardrail 5. A top rod 24 is fixedly installed on the upper end of the button 8. The upper end of the top rod 24 passes through the movable rod 4 and abuts against the slope groove 17. The top rod 24, located between the movable rod 4 and the button 8, is also fitted with a second compression spring 25. The second compression spring 25 provides a downward elastic return thrust to the button 8, keeping the top rod 24 abutting against the slope groove 17, thereby locking the relative position between the movable rod 4 and the guardrail 5, keeping the guardrail 2 stably in the unfolded state, and allowing the button 8 to be pressed.

[0028] When it is necessary to fold and store the guardrail 2, such as Figures 2-3As shown, the operator only needs to press the button 8 upwards. The button 8 moves upwards against the elastic force of the second compression spring 25, causing the top rod 24 to rise synchronously. Because the end of the limiting rod 6 away from the slope groove 17 has a spring groove 20, the first compression spring 21 is inserted into the spring groove 20. One end of the first compression spring 21 is inserted into the inner wall of the movable rod 4. The upper end of the top rod 24 is pushed along the slope of the slope groove 17, thereby pushing the limiting rod 6 to overcome the elastic force of the first compression spring 21 and slide along the guide rail 16 away from the buckle box 7, so that the limiting rod 6 moves axially as a whole. As the limiting rod 6 slides, the buckle 23 fixedly connected to the lower end of the button 8 rises with the button 8 and completely disengages from the buckle groove 22, releasing the insertion limit between the buckle 23 and the buckle seat 9. At this time, the operator can press the movable rod 4 downwards, and through the hinge rotation of multiple surrounding rods 5, the guardrail 2 is folded back to the side of the nursing bed 1.

[0029] When it is necessary to use the tabletop 10 above the nursing bed 1, such as Figures 2-6 As shown, the operator places the tabletop 10 between two movable rods 4 in the unfolded state, aligning the slots 12 at the lower ends of the mounting blocks 11 fixed on both sides of the tabletop 10 with the corresponding movable rods 4, and then engages the slots 12 with the movable rods 4 from top to bottom. After the tabletop 10 is in place, multiple pins 26 fixedly installed on the inner top surface of the slots 12 fall down with the tabletop 10. Since the upper end of the movable rod 4 has multiple limiting holes 15 along its axial direction, and the upper end of the limiting rod 6 has a number of limiting grooves 19 along its axial direction that match the number of limiting holes 15, and each limiting groove 19 is coaxially arranged with the corresponding limiting hole 15, and multiple pins 26 are fixedly installed on the inner top surface of the slots 12, the lower end of each pin 26 passes through the corresponding limiting hole 15 and is inserted into the corresponding limiting groove 19. Inside the 9th section, the insertion and engagement of the pin 26 with the limiting groove 19 limits the axial sliding of the limiting rod 6, preventing the limiting rod 6 from moving axially along the guide rail 16. This fixes the relative position of the slope groove 17 and the upper end of the top rod 24. Even if the operator accidentally touches or presses the button 8, the top rod 24 cannot push the limiting rod 6 axially along the slope of the slope groove 17. Consequently, the latch 23 cannot disengage from the latch groove 22, effectively preventing the guardrail 2 from being accidentally folded and stored due to the button 8 being misoperated. This avoids the risk of the table 10 tipping over due to the guardrail 2 collapsing. When the table 10 needs to be removed, the operator pulls the table 10 upwards, causing the pin 26 to exit from the limiting groove 19 and the limiting hole 15. The limiting rod 6 then regains its axial sliding freedom, and the normal unlocking function of the button 8 is restored.

[0030] The guide sleeve, top rod 24, latch 23, and elastic element work together to form a reliable mechanical interlocking transmission chain. When button 8 is pressed, top rod 24 moves upward to push limit rod 6, while latch 23 disengages from latch slot 22 of latch seat 9, unlocking guardrail 2. When button 8 is released, elastic element forces button 8 to reset, and latch 23 re-inserts into latch slot 22, ensuring stable locking of guardrail 2. Compared to the simple snap-fit ​​structure in existing technologies, this solution integrates the unlocking action and locking function into a single button 8, resulting in a compact structure and convenient operation. The addition of the guide sleeve ensures that button 8 slides only along the axial direction, avoiding jamming or unlocking failure due to misalignment. This significantly improves the operational reliability and lifespan of the guardrail 2 locking mechanism in frequent use scenarios, making it particularly suitable for clinical nursing conditions where guardrail 2 needs to be repeatedly opened and closed.

[0031] An anti-slip pad is added to the lower surface of the tabletop 10, and the anti-slip pad and the upper surface of the movable rod 4 abut against each other when the tabletop 10 is engaged with the movable rod 4, forming an elastic pressing contact interface. This design not only increases the static friction between the tabletop 10 and the movable rod 4, effectively preventing the tabletop 10 from shifting or deviating along the axial direction of the movable rod 4 when subjected to lateral thrust or bed vibration, but also uses the elastic deformation of the anti-slip pad to compensate for the processing and assembly gap between the slot 12 and the movable rod 4, avoiding noise or affecting the stability of patients eating or taking medication due to the existence of gaps. Compared with the traditional method of direct engagement with a rigid slot 12, this solution significantly improves the positioning accuracy and anti-slip performance of the tabletop 10 in clinical use, and the anti-slip pad itself has a buffering and vibration-absorbing effect, which can reduce the risk of tabletop items tipping over due to accidental bumps, further ensuring patient safety.

[0032] A buffer sleeve is fitted onto the guardrail 5 between the fixed rod 3 and the movable rod 4. During the folding process of the guardrail 2, the buffer sleeve can elastically abut against the adjacent guardrail 5 and the fixed rod 3, forming a multi-level buffering and damping effect. Specifically, when the movable rod 4 folds along the guardrail 5 around the hinge point towards the fixed rod 3, the buffer sleeve first contacts the adjacent guardrail 5 and compresses and deforms, absorbing most of the folding impact energy. Subsequently, the buffer sleeve abuts against the fixed rod 3, further limiting the rigid collision at the end of the folding. Compared with the traditional design where there is direct rigid contact between the guardrail 5 and between the guardrail 5 and the fixed rod 3 during the folding of the guardrail 2, this solution effectively avoids the noise and wear of hard impact between metal parts, and extends the service life of the hinge part of the guardrail 2. At the same time, the elastic restoring force of the buffer sleeve provides a certain assistance when the guardrail 2 is unfolded, making the unfolding operation of the guardrail 2 easier and smoother, especially suitable for the strict requirements of low-noise operation at night or in quiet nursing environments.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
