[0021] like Figure 1 、 Figure 2 、 Figure 4 As shown, an embodiment of the present invention provides a baby crib, comprising a bed body assembly 1, a swing arm 2, a push handle assembly 3 and a mounting column 4; the bottom of the bed body assembly 1 is connected to the first end 21 of the swing arm 2 via a first rotating connection mechanism, the first rotating connection mechanism comprises one of a tilt adjustment mechanism 5 and a rotation mechanism 9, the tilt adjustment mechanism 5 is constructed to adjust the tilt angle of the bed body assembly 1 relative to the swing arm 2, the rotation mechanism 9 is constructed to drive the bed body assembly 1 to rotate relative to the swing arm 2 around a vertical axis; the second end 22 of the swing arm 2 is pivotally connected to the push handle assembly 3 via a swing mechanism 6, the swing mechanism 6 is configured to enable the swing arm 2 to swing around a vertical axis relative to the push handle assembly 3; the push handle assembly 3 is liftably connected to the top of the mounting column 4 via a height adjustment mechanism 7, the height adjustment mechanism 7 is used to adjust the height of the push handle assembly 3 relative to the mounting column 4.

[0022] Specifically, the bed assembly 1 is the main load-bearing portion of the crib, used to accommodate newborns or infants. The bottom of the bed assembly 1 is connected to the first end 21 of the swing arm 2 via a first rotating connection mechanism. This first rotating connection mechanism can be in two forms: a tilt adjustment mechanism 5 or a rotation mechanism 9. When the tilt adjustment mechanism 5 is used, it allows the bed assembly 1 to tilt relative to the swing arm 2. For example, in a neonatal emergency setting, depending on the patient's condition, the bed may need to be adjusted to a head-high, feet-low position or head-low, feet-high position. The tilt adjustment mechanism 5 facilitates this function by changing the angle between the bed and the swing arm 2 to meet different treatment needs. When the rotation mechanism 9 is used, it drives the bed assembly 1 to rotate about a vertical axis relative to the swing arm 2. During rehabilitation care, the patient's orientation may need to be changed to allow medical staff to provide care from different angles. The rotation mechanism 9 allows the bed assembly 1 to rotate about a vertical axis, facilitating operation. The tilt adjustment mechanism 5 can take various forms. For example, it can include a structure comprising a rotating shaft and a bearing. The rotating shaft is fixed to the first end 21 of the swing arm 2, and the bottom of the bed assembly 1 is connected to the rotating shaft and rotated via the bearing. Alternatively, the tilt adjustment mechanism 5 can be electrically driven, with the motor driving related components to enable the bed assembly 1 to rotate smoothly relative to the swing arm 2, thereby adjusting the tilt angle. The tilt angle adjustment range can be designed according to actual needs to meet the needs of different nursing scenarios. The rotating mechanism 9 can include a rotating drive motor, a rotating transmission component, and a rotating support base. For example, the rotating drive motor, via the rotating transmission component, drives the bed assembly 1 to rotate about a vertical axis relative to the swing arm 2, with a rotation angle range of 0-360°. The swing arm 2 serves to connect the bed assembly 1 and the push handle assembly 3. Its second end 22 is pivotally connected to the push handle assembly 3 via a swing mechanism 6. The swing mechanism 6 enables the swing arm 2 to swing relative to the push handle assembly 3. This swing function can further adjust the horizontal position or angle of the bed assembly 1, meeting the diverse requirements for bed position and posture during different nursing operations. For example, when the crib needs to be moved closer to or further away from certain medical equipment, or when the baby is being coaxed to sleep, this operation can be conveniently achieved by swinging the swing arm 2. The swing mechanism 6 can be designed as a hinge-like structure so that the swing arm 2 can swing around the connection point with the push handle assembly 3. The swing mechanism 6 can also be driven electrically or manually. For example, the manual swing mechanism 6 can be provided with a handle 32, and the medical staff can control the swing of the swing arm 2 by turning the handle 32; the electric swing mechanism 6 can be driven by a motor to achieve automatic swinging of the swing arm 2, and the swing angle and speed can be set as needed. On the one hand, the push handle assembly 3 provides convenience for medical staff to push the crib, and on the other hand, it is connected to the top of the mounting column 4 in a liftable manner through the height adjustment mechanism 7.By operating the height adjustment mechanism 7, medical personnel can change the height of the handle assembly 3 relative to the mounting post 4, thereby raising or lowering the entire crib (including the bed assembly 1, swing arm 2, and handle assembly 3). This feature allows the height of the crib to be adjusted according to different usage scenarios and the medical personnel's work needs, making operation more convenient and comfortable. For example, height adjustment can easily facilitate docking of the crib with medical beds of different heights. The height adjustment mechanism 7 can adopt a screw-nut mechanism, with a screw installed inside the mounting post 4 and a nut connected to the handle assembly 3. Rotating the screw or nut adjusts the height of the handle assembly 3 relative to the mounting post 4. Alternatively, a hydraulic or pneumatic adjustment mechanism can be used to control the hydraulic or pneumatic pressure to raise or lower the handle assembly 3. The height adjustment mechanism 7 can also be equipped with a locking device to lock the position of the handle assembly 3 after adjusting to the desired height, ensuring the stability of the crib. The mounting post 4 serves as the support base of the entire crib, and its bottom can be designed as a stable base structure to ensure the stability of the crib during use. The height of the mounting post 4 can be designed to meet different height requirements based on actual usage scenarios. At the same time, the mounting column 4 may also be provided with some auxiliary components, such as a power interface (if the crib is equipped with an electric adjustment mechanism), a fixing device (for fixing the crib in a specific position), etc., to improve the practicality and safety of the crib.

[0023] In this embodiment, the crib features multiple adjustment functions, allowing medical staff to adjust the bed's posture, position, and height in real time based on the patient's physiological condition and treatment needs, without the need for external tools or collaboration. For example, during neonatal emergency care, the bed can be quickly adjusted to the appropriate tilt angle, saving time and improving emergency care efficiency. The crib's various adjustment mechanisms (tilt adjustment mechanism 5, rotation mechanism 9, swing mechanism 6, and height adjustment mechanism 7) work together to ensure smooth and reliable adjustment of the bed assembly 1, avoiding safety issues caused by improper operation or unstable equipment, and providing a safer care environment for newborns and infants. This combination of adjustment functions makes the crib adaptable to a variety of clinical care scenarios, including neonatal emergency care, postural drainage, and rehabilitation care. Whether adjusting the patient's position, bed orientation, or bed height, the crib can meet the needs of diverse care operations, providing medical staff with a more flexible and convenient care tool and helping to improve the quality of care.

[0024] Alternatively, as Figure 3As shown, the inclination adjustment mechanism 5 includes a mounting plate 51 and a locking pin 52 connected to the bottom of the bed assembly 1. The lower end of the mounting plate 51 is connected to a support block 53, and the support block 53 is rotatably connected to the first end 21 of the swing arm 2 through a first rotating shaft 54. The end of the support block 53 away from the first rotating shaft 54 ​​is provided with a plurality of adjustment holes 531 spaced apart in the vertical direction, and the side wall of the first end 21 of the swing arm 2 is provided with an adjustment through hole 211 corresponding to the adjustment hole 531. The locking pin 52 can be detachably passed through the adjustment through hole 211 and selectively inserted into any adjustment hole 531 to form an angle lock.

[0025] Specifically, the mounting plate 51 is connected to the bottom of the bed assembly 1, and a support block 53 is connected to its lower end. The support block 53 is rotatably connected to the first end 21 of the swing arm 2 via a first rotating shaft 54. This allows the bed assembly 1 to rotate relative to the swing arm 2 about the first rotating shaft 54, thereby achieving preliminary adjustment of the tilt angle of the bed assembly 1. During the adjustment process, medical personnel can manually push the bed assembly 1, driving the mounting plate 51 and the support block 53 to rotate around the first rotating shaft 54, thereby changing the angle between the bed assembly 1 and the horizontal plane. The end of the support block 53 away from the first rotating shaft 54 ​​is provided with three adjustment holes 531 spaced apart in the vertical direction, and the side wall of the first end 21 of the swing arm 2 is provided with an adjustment through-hole 211 corresponding to the adjustment holes 531. When the bed assembly 1 is rotated to the appropriate tilt angle, the medical personnel inserts the locking pin 52 through the adjustment through-hole 211 and selectively inserts it into any of the adjustment holes 531. At this time, the locking pin 52 serves to fix the relative position of the support block 53 and the swing arm 2, preventing the support block 53 from further rotating, thereby locking the tilt angle of the bed assembly 1. In this embodiment, when the locking pin 52 passes through the adjustment hole 211 and is inserted into the adjustment hole 531 located in the middle position, the bed assembly 1 is in a horizontal state.

[0026] In this optional embodiment, by providing a plurality of adjustment holes 531 spaced apart, medical personnel can adjust the bed assembly 1 to a more precise tilt angle according to actual needs. Furthermore, after the locking pin 52 is inserted into the adjustment hole 531, it can firmly fix the relative position of the support block 53 and the swing arm 2, preventing the bed assembly 1 from shaking or changing angles due to external forces during use, thereby ensuring the stability of the baby bed in the tilted state and providing a safe and reliable care environment for the child. Furthermore, the adjustment method of the tilt adjustment mechanism 5 of this embodiment is relatively simple. Medical personnel do not need complex operating procedures or professional tools. They only need to manually push the bed assembly 1 to the appropriate angle and then insert the locking pin 52 into the corresponding adjustment hole 531 to complete the angle adjustment and locking. This greatly improves the convenience of operation and saves time and energy. Especially in emergency care situations, it can quickly adjust the bed posture.

[0027] Alternatively, as Figure 3As shown, the first end 21 of the swing arm 2 is provided with a strip-shaped avoidance groove 212 extending along its length direction, the support block 53 is rotatably connected in the avoidance groove 212 and the two are clearance-matched to form a rotation space, and the axial direction of the first rotating shaft 54 ​​is perpendicular to the extension direction of the avoidance groove 212.

[0028] Specifically, the first end 21 of the swing arm 2 is provided with a strip-shaped escape groove 212 extending along its length. The support block 53 is pivotally connected to the escape groove 212, with a clearance fit between the two, creating a certain amount of rotational space. When the tilt angle of the bed assembly 1 needs to be adjusted, the support block 53 rotates around the first rotation axis 54 within the rotational space formed by the escape groove 212. Because the axial direction of the first rotation axis 54 is perpendicular to the extension direction of the escape groove 212, the support block 53 can rotate stably within a plane perpendicular to the extension direction of the escape groove 212, thereby driving the bed assembly 1 to adjust its tilt angle. The strip-shaped escape groove 212 provides sufficient space for the support block 53 to rotate, preventing interference between the support block 53 and the swing arm 2 during rotation. During the tilt angle adjustment process of the bed assembly 1, the support block 53 can rotate freely within the escape groove 212 without being obstructed by other parts of the swing arm 2, ensuring smooth and accurate tilt angle adjustment.

[0029] In this optional embodiment, the rotation space formed by the strip avoidance groove 212 and the clearance fit allows the support block 53 to have a larger range of motion when rotating, and is not restricted by the structure of the swing arm 2. This greatly improves the flexibility of adjusting the tilt angle of the bed assembly 1. Medical staff can more freely adjust the tilt angle of the bed assembly 1 according to actual needs to meet the requirements of different clinical care scenarios. Because the axial direction of the first rotating shaft 54 ​​is perpendicular to the extension direction of the avoidance groove 212, the support block 53 can maintain a stable posture during rotation without shaking or offsetting. This stable rotation method helps to ensure the stability of the baby bed during use and provide a safer and more reliable care environment for the child. The design of the strip avoidance groove 212 cleverly utilizes the space of the swing arm 2, providing the necessary space for the rotation of the support block 53 without affecting the overall structural strength of the swing arm 2. It is not only simple and reasonable, but also can effectively reduce friction and wear between components, thereby extending the service life of the baby bed.

[0030] Alternatively, as Figure 5 、 Figure 6As shown, the rotating mechanism 9 includes a third rotating shaft 91, a clamp 92 and a locking assembly 93. The first end 21 of the swing arm 2 is provided with a mounting cavity 23 with an upward opening. The third rotating shaft 91 is rotatably connected in the mounting cavity 23. The lower end of the bed assembly 1 is connected to the mounting plate 51, and the mounting plate 51 is connected to the upper end of the third rotating shaft 91. The clamp 92 is connected in the mounting cavity 23 and clamped on the outer periphery of the third rotating shaft 91. The locking assembly 93 is connected to one side of the clamp 92 for clamping or loosening the clamp 92. Specifically, the first end 21 of the swing arm 2 is provided with an open mounting cavity 23, providing mounting space for components such as the third rotating shaft 91. The third rotating shaft 91 is rotatably connected within the mounting cavity 23, providing the foundation for the rotation mechanism 9 to function, allowing the third rotating shaft 91 to rotate freely within the mounting cavity 23. A mounting plate 51 is connected to the lower end of the bed assembly 1, which is further connected to the upper end of the third rotating shaft 91. This secures the bed assembly 1 to the third rotating shaft 91 via the mounting plate 51. When the third rotating shaft 91 rotates, it drives the bed assembly 1 to rotate as well. A clamp 92 is connected within the mounting cavity 23 and clips onto the outer periphery of the third rotating shaft 91. The clamp 92 provides positioning and auxiliary support for the third rotating shaft 91, preventing it from shifting or shaking during rotation and ensuring rotational stability. A locking assembly 93 is connected to one side of the clamp 92. Controlling the locking assembly 93 allows the clamp 92 to be tightened or loosened. When the rotation angle of the bed assembly 1 needs to be adjusted, the locking assembly 93 is loosened so that the clamp 92 no longer tightly clamps the third rotating shaft 91. At this time, the third rotating shaft 91 can rotate freely, and the medical staff can manually rotate the bed assembly 1 to the desired angle. When the bed assembly 1 is rotated to the appropriate angle, the locking assembly 93 is locked, and the clamp 92 re-clamps the third rotating shaft 91, fixing the third rotating shaft 91 in the current position, thereby fixing the rotation angle of the bed assembly 1 and ensuring that the bed assembly 1 will not rotate accidentally due to external forces or other factors during the nursing process.

[0031] In this optional embodiment, the clamp 92 is clamped to the outer periphery of the third rotating shaft 91, which plays a good positioning and supporting role for the third rotating shaft 91, and can effectively reduce the shaking and deviation of the third rotating shaft 91 during the rotation process, making the rotation of the bed assembly 1 more stable and stable, improving the safety of the baby bed, and avoiding harm to the child due to unstable rotation. The clamping and loosening of the clamp 92 can be easily controlled by the locking assembly 93, thereby achieving control over the rotation of the third rotating shaft 91. After loosening the clamp 92, medical staff can accurately rotate the bed assembly 1 to the desired angle, and then lock the clamp 92 to fix the angle. This adjustment method can meet the precise requirements for the rotation angle of the bed assembly 1 in different nursing scenarios, thereby improving the accuracy and effectiveness of nursing operations.

[0032] Alternatively, as Figure 5 、 Figure 6 As shown, the locking assembly 93 includes a guide block 931, a cam 932 and a handle 933. The guide block 931 is connected to one side of the clamp 92. An arc-shaped guide surface 9311 is provided on the guide block 931. The cam 932 is rotatably connected to one side of the guide block 931 and fits with the guide surface. The handle 933 is connected to one side of the cam 932. An avoidance hole 231 is provided on the cavity wall of the installation cavity 23. One end of the handle 933 extends out of the installation cavity 23 through the avoidance hole 231.

[0033] Specifically, the guide block 931 is connected to one side of the clamp 92, providing a basis for installation and guidance of the cam 932. An arc-shaped guide surface 9311 is provided on the guide block 931, and the cam 932 is rotatably connected to one side of the guide block 931 and fits with the guide surface. This structure enables the cam 932 to move along the trajectory of the guide surface during rotation. The handle 933 is connected to one side of the cam 932, and a avoidance hole 231 is provided on the cavity wall of the installation cavity 23. One end of the handle 933 extends out of the installation cavity 23 through the avoidance hole 231. Medical staff can control the rotation of the cam 932 by operating the handle 933. When the clamp 92 needs to be locked, the medical staff manually rotates the handle 933, and the handle 933 drives the cam 932 to rotate. Because the cam 932 is in contact with the curved guide surface 9311 of the guide block 931, as the cam 932 rotates, the outer edge of the cam 932 gradually squeezes the guide block 931, thereby applying pressure to the clamp 92, causing the clamp 92 to further clamp the third rotating shaft 91, thereby achieving the purpose of locking. When it is necessary to loosen the clamp 92, the medical staff rotates the handle 933 in the opposite direction, and the cam 932 rotates in the opposite direction. The pressure of the cam 932 on the guide block 931 gradually decreases, and the clamp 92 is no longer subjected to the strong clamping force, thereby loosening the third rotating shaft 91, making it easier for the medical staff to adjust the rotation angle of the bed assembly 1.

[0034] In this optional embodiment, the handle 933 extends out of the mounting cavity 23 through the avoidance hole 231. Medical personnel do not need to open the mounting cavity 23 or perform complicated operations. They only need to rotate the handle 933 outside the mounting cavity 23 to lock and loosen the clamp 92. The operation is simple and convenient, which greatly improves work efficiency, especially in emergency care situations, and can quickly adjust the rotation angle of the baby bed. Through the cooperation of the cam 932 and the guide block 931, medical personnel can control the rotation angle of the handle 933 according to actual needs, thereby adjusting the degree of compression of the cam 932 on the guide block 931, and then adjusting the clamping force of the clamp 92 on the third rotating shaft 91. The adjustable locking force can adapt to different nursing needs and working environments, ensuring that the bed assembly 1 can be firmly and stably fixed when it needs to be fixed, and can be easily loosened when it needs to be adjusted. The locking assembly 93 adopts a combined structure of a guide block 931, a cam 932 and a handle 933. The overall structure is compact and occupies little space, so that the rotating mechanism 9 can be better installed in the installation cavity 23 of the crib without causing excessive interference with other components and the overall structure of the crib. At the same time, it also facilitates the miniaturization and lightweight design of the crib.

[0035] Alternatively, as Figure 7 As shown, the swing mechanism 6 includes a second rotating shaft 61 and a positioning pin 62, the push hand assembly 3 includes a push hand plate 31, a rotating hole 311 is provided on the push hand plate 31, the second rotating shaft 61 is rotatably connected in the rotating hole 311, the second end 22 of the swing arm 2 is connected to the upper end of the second rotating shaft 61, the second end 22 of the swing arm 2 is provided with a threaded through hole 221 in the vertical direction, the second rotating shaft 61 is provided with a positioning through hole 611 connected to the threaded through hole 221, and a positioning groove 312 is provided on the push hand plate 31. The positioning pin 62 is threadedly connected to the threaded through hole 221 and extends into the positioning through hole 611 and the corresponding positioning groove 312. When the positioning pin 62 disengages from the positioning groove 312, the swing arm 2 is allowed to swing relative to the push hand plate 31; when the positioning pin 62 is inserted into the positioning groove 312, the swing position of the swing arm 2 is locked.

[0036] Specifically, the push handle plate 31 of the push handle assembly 3 is provided with a rotation hole 311, and the second rotating shaft 61 is rotatably connected to the rotation hole 311. The second end 22 of the swing arm 2 is connected to the upper end of the second rotating shaft 61. This connection method allows the swing arm 2 and the second rotating shaft 61 to swing relative to the push handle plate 31 with the rotation hole 311 as the center. When the swing arm 2 needs to swing relative to the push handle plate 31, the medical staff unscrews the positioning pin 62 from the threaded through hole 221, the positioning through hole 611, and the positioning groove 312, so that the positioning pin 62 disengages the positioning groove 312. At this time, the lock between the swing arm 2, the second rotating shaft 61, and the push handle plate 31 is released, and the swing arm 2 and the second rotating shaft 61 can swing freely around the rotation hole 311. The medical staff can adjust the position of the swing arm 2 according to the actual nursing needs, thereby driving the bed assembly 1 to adjust to the appropriate position and angle. After swing arm 2 has swung to the desired position, the medical professional rethreads locating pin 62 into threaded through hole 221 and inserts it through locating through hole 611 into the corresponding locating slot 312. The engagement of locating pin 62 with locating slot 312 locks the swing arm 2 in its swing position, preventing it from swinging unnecessarily due to external forces during use and ensuring the stability of the crib. In this embodiment, the push handle assembly 3 also includes a handle 32 connected to one side of the push handle plate 31 to facilitate pushing the crib.

[0037] In this optional embodiment, the locking and unlocking of the swing arm 2 are achieved through the cooperation of the positioning pin 62 and the positioning slot 312, making the operation simple and easy to understand. Medical personnel only need to screw in or out the positioning pin 62 to switch the swing arm 2's swinging state, eliminating the need for complex operating procedures or specialized tools. This greatly improves operational convenience and enables rapid response to various clinical care needs. The design of the positioning pin 62 threadedly connected to the threaded through hole 221 and extending into the positioning slot 312 allows the swing arm 2 to be securely fixed in the desired position when locked, ensuring the accuracy and stability of the swing arm 2's swinging position, preventing the overall stability of the crib from being affected by the swing arm 2's shaking, and providing a safer and more reliable nursing environment for the child. Furthermore, the swing mechanism 6 of this embodiment, primarily composed of the second rotating shaft 61, the positioning pin 62, the push handle 31, and other components, has a relatively simple structure, which not only reduces production costs but also reduces the probability of malfunction, thereby improving the reliability and durability of the crib. Furthermore, the connection and coordination between the various components are relatively intuitive, making them easy to manufacture and maintain.

[0038] Alternatively, as Figure 7 As shown, an arc-shaped rotation groove 612 is provided at the bottom of the second rotating shaft 61, and a limit pin 313 is provided on the push plate 31. The limit pin 313 extends into the rotation groove 612 and can slide along the arc-shaped track of the rotation groove 612 to limit the swing angle range of the swing arm 2.

[0039] Specifically, the swing arm 2 swings relative to the push handle plate 31 about the second rotating shaft 61. During this swinging process, the second rotating shaft 61 rotates accordingly. Because the bottom of the second rotating shaft 61 is provided with an arc-shaped rotation groove 612, the stop pin 313 provided on the push handle plate 31 extends into this rotation groove 612. When the swing arm 2 swings, the second rotating shaft 61 drives the rotation groove 612 to rotate, while the stop pin 313 slides within the rotation groove 612 along a sliding path that matches the arc of the rotation groove 612. When the swing arm 2 swings to a certain angle, the stop pin 313 slides to the end of the rotation groove 612. At this time, the stop pin 313 and the end of the rotation groove 612 interfere with each other, preventing the second rotating shaft 61 from further rotation. This, in turn, limits the swing angle range of the swing arm 2 and prevents it from swinging excessively. In this embodiment, when the positioning pin 62 is inserted into the positioning groove 312 and the swing arm 2 is in the locked position, the stop pin 313 is located in the middle of the rotation groove 612.

[0040] In this optional embodiment, by setting a limit pin 313 and a rotating slot 612 to limit the swing angle range of the swing arm 2, it is possible to effectively prevent the swing arm 2 from colliding with other components due to excessive swinging, or causing instability in the overall structure of the crib, thereby ensuring the safety of the crib during use and providing a more reliable nursing environment for the child. The swing angle range of the swing arm 2 is clarified, so that medical staff can more accurately control the position of the swing arm 2 when operating the crib, improving the accuracy and controllability of the operation. Medical staff can flexibly adjust the swing arm 2 within the specified angle range according to actual needs to meet the needs of different nursing scenarios. Limiting the swing angle range of the swing arm 2 can reduce the wear and stress concentration of the swing arm 2 and related components during the swinging process, reduce the risk of component damage due to excessive swinging, thereby extending the service life of the crib and reducing maintenance and replacement costs.

[0041] Alternatively, as Figure 2 、 Figure 8 As shown, the height adjustment mechanism 7 includes a lifting column 71 and a gas spring 72. The lifting column 71 is sleeved on the outside of the mounting column 4. The push handle assembly 3 includes a push handle plate 31. The push handle plate 31 is connected to the top of the lifting column 71. A gas spring 72 is provided in the mounting column 4. An adjustment button 314 is provided on the push handle plate 31. The bottom end of the gas spring 72 is connected to the bottom of the mounting column 4. The top of the gas spring 72 is connected to a control head 721. A control line 73 is connected between the control head 721 and the adjustment button 314. The adjustment button 314 controls the control head 721 through the control line 73, thereby opening or closing the gas spring 72 to realize the lifting and lowering of the push handle plate 31.

[0042] Specifically, the height adjustment mechanism 7 consists of a lifting column 71 and a gas spring 72. The lifting column 71 is mounted on the outside of the mounting column 4, the handle plate 31 is connected to the top of the lifting column 71, and the gas spring 72 is arranged inside the mounting column 4. One end of the gas spring 72 is connected to the bottom of the mounting column 4, and the other end is connected to the control head 721. The control head 721 is connected to the adjustment button 314 on the handle plate 31 via a control line 73. At this time, the gas spring 72 is in the closed state, supporting the lifting column 71, so that the handle plate 31 and connected components are maintained at a specific height. Height adjustment process: When the height of the handle plate 31 needs to be adjusted, the medical staff presses the adjustment button 314. The adjustment button 314 sends a signal to the control head 721 via the control line 73. After receiving the signal, the control head 721 triggers the valve or piston and other key components inside the gas spring 72 to operate, causing the gas spring 72 to open. The gas or hydraulic medium within gas spring 72 begins to flow, generating a force that pushes lifting column 71 upward or downward along mounting column 4 (the specific direction depends on the design and installation of gas spring 72), thereby raising or lowering handle plate 31. When handle plate 31 reaches the desired height, the medical staff releases adjustment button 314, which sends a stop signal to control head 721 via control line 73. Control head 721 closes gas spring 72, restoring the internal force of gas spring 72 to a stable state and locking lifting column 71 in its current position, thereby fixing the height of handle plate 31. In this embodiment, a mounting block 74 is connected to the outside of lifting column 71. Mounting block 74 is mounted with a storage basket 75 for placing baby care items for convenient use.

[0043] In this optional embodiment, the gas spring 72 is controlled by adjusting the button 314, the control line 73, and the control head 721 to control the opening and closing of the gas spring 72, thereby achieving the raising and lowering of the push plate 31. Medical personnel only need to press the adjustment button 314 to complete the height adjustment operation, without the need for complex tools or tedious manual adjustments. This greatly improves the convenience and efficiency of operation and can quickly respond to the needs of medical personnel of different heights in clinical nursing. The gas spring 72 has a buffering and stabilizing effect, providing a uniform force during the lifting process, ensuring smooth movement of the lifting column 71, avoiding shaking and impact caused by rapid or sudden movement, and ensuring the smooth adjustment of the height of the push plate 31. At the same time, medical personnel can precisely control the height of the push plate 31 according to actual needs, improving the accuracy of adjustment and providing a more comfortable and appropriate working height for nursing work.

[0044] Alternatively, as Figure 8 As shown, a self-locking switch 7211 is rotatably connected to the control head 721, one end of the control line 73 is connected to the self-locking switch 7211, and the adjustment button 314 is slidably connected to the push plate 31. When the adjustment button 314 is forced to slide upward, the self-locking switch 7211 is pulled through the control line 73 to release the lock of the gas spring 72.

[0045] Specifically, the gas spring 72 is in a locked state, the self-locking switch 7211 is in a closed or specific locked position, the control line 73 is connected to the self-locking switch 7211, and the adjustment button 314 is slidably connected to the push handle plate 31 and is in its initial position. At this point, the control line 73 does not apply tension to the self-locking switch 7211, and the gas spring 72 maintains its internal piston, valve, and other components in a locked state. The lifting column 71 and the push handle plate 31 are fixed at a certain height. When medical personnel need to adjust the height of the push handle plate 31, they apply an upward force to the adjustment button 314, causing it to slide upward on the push handle plate 31. Because one end of the control line 73 is connected to the adjustment button 314 and the other end is connected to the self-locking switch 7211, the upward sliding of the adjustment button 314 pulls on the control line 73. The tension of the control line 73 is transmitted to the self-locking switch 7211, causing it to rotate or move, thereby releasing the lock of the gas spring 72. After the gas spring 72 is unlocked, the medical staff can manually push or rely on the inherent characteristics of the gas spring 72 to cause the lifting column 71 to raise or lower the handle plate 31. When the handle plate 31 reaches the desired height, the medical staff releases the adjustment button 314. The adjustment button 314 slides downward to its initial position under its own gravity or other reset mechanism (such as a spring). The tension of the control wire 73 on the self-locking switch 7211 disappears, and the self-locking switch 7211 returns to its original position, relocking the gas spring 72 and fixing the lifting column 71 and the handle plate 31 at the current height.

[0046] In this optional embodiment, the locking and unlocking of the gas spring 72 is controlled by sliding the adjustment button 314. The operation is simple and intuitive. Medical staff can complete the operation with just one hand, without the need for complex steps or professional knowledge. This greatly improves the convenience and efficiency of operation and can quickly adapt to the need for frequent height adjustment in clinical care. The gas spring 72 is locked and unlocked using a self-locking switch 7211. The self-locking switch 7211 has a stable mechanical structure and a reliable self-locking function. It can accurately respond to the pull of the adjustment button 314, ensuring that the gas spring 72 can be reliably unlocked or restored when needed, thereby ensuring the accuracy and stability of height adjustment. The locking function of the self-locking switch 7211 can effectively prevent the gas spring 72 from being accidentally unlocked when not in operation, avoiding safety hazards caused by the sudden rise and fall of the push plate 31, and ensuring the safety of medical staff and children.

[0047] Alternatively, as Figure 9As shown, the bed assembly 1 includes a baby basin 11, and an avoidance opening 111 is provided on one side of the baby basin 11. A baffle 12 is rotatably connected to the avoidance opening 111, and a fixing groove 121 is provided on the baffle 12. Fixed pins 112 are slidably connected to both sides of the avoidance opening 111. When the baffle 12 is rotated to close the avoidance opening 111, the fixing pins 112 slide into the fixing groove 121 to fix the position of the baffle 12.

[0048] Specifically, the infant basin 11 in the bed assembly 1 is in normal use, with the baffle 12 in a position closing the escape opening 111. When a healthcare professional performs specific operations on the infant, such as placing or removing items or providing care to a specific part of the infant's body, the healthcare professional reverses the operation of the securing pins 112, causing them to slide out of the securing slots 121, releasing the securing of the baffle 12. The healthcare professional then manually rotates the baffle 12 to open the escape opening 111. When the healthcare professional completes the operation and needs to close the escape opening 111 to ensure the infant's safety or prevent external interference, the healthcare professional manually rotates the baffle 12, gradually moving it toward the direction of closing the escape opening 111. When the baffle 12 is rotated to fully close the escape opening 111, the healthcare professional operates the securing pins 112 on either side of the escape opening 111, causing them to slide along the sliding direction into the securing slots 121 on the baffle 12. The cooperation between the fixing pin 112 and the fixing slot 121 limits the rotational freedom of the baffle 12, thereby firmly fixing the baffle 12 in a position to close the avoidance opening 111, ensuring that the baby basin 11 forms a relatively closed space, and protecting the safety and comfort of the baby.

[0049] In this optional embodiment, the opening and closing of the escape opening 111 is achieved by rotating the baffle 12 and sliding the fixing pin 112. This simple and intuitive operation allows medical personnel to quickly open and close the escape opening 111 according to care needs without using complex tools or performing tedious steps, thereby improving work efficiency. When the baffle 12 is closed, the engagement of the fixing pin 112 with the fixing slot 121 reliably secures the baffle 12 in place, preventing it from opening automatically in unexpected circumstances. This avoids potential harm to the infant caused by the opening of the baffle 12, such as the infant slipping through the escape opening 111, thereby providing a safer care environment for the infant. The provision of the escape opening 111 allows medical personnel to conveniently perform operations within or near the infant basin 11, such as placing care products and conducting medical examinations, without moving the infant. This fully utilizes the space surrounding the bed assembly 1, improving the convenience and space utilization of care operations.

[0050] Alternatively, as Figure 9As shown, the baby basin 11 is provided with pressure plates 113 on both sides of the avoidance opening 111, and a card slot 1131 is provided on the pressure plate 113. A torsion spring 114 is embedded in the card slot 1131. The outer side of the pressure plate 113 is rotatably connected to a rotating disk 115. A card block 1151 is provided on the inner side of the rotating basin. The free end of the torsion spring 114 abuts against the card block 1151. The two ends of the baffle 12 are respectively connected to the outer side of the rotating disk 115. The baffle 12 is provided with a cover plate 116 on the outer side of the rotating disk 115.

[0051] Specifically, in the initial state, the baffle 12 closes the avoidance opening 111, and the free end of the torsion spring 114 abuts against the block 1151, but is not compressed or twisted, and is in a naturally extended state. When the medical staff needs to open the baffle 12, they first release the fixation of the baffle 12 and manually apply external force to push the baffle 12. The baffle 12 drives the rotating disk 115 to rotate around the mounting plate 51, and the block 1151 on the inner side of the rotating disk 115 rotates accordingly. The block 1151 begins to apply pressure to the free end of the torsion spring 114, causing the torsion spring 114 to gradually be compressed or twisted, storing elastic potential energy. As the baffle 12 continues to rotate, the elastic potential energy stored in the torsion spring 114 continues to increase until the baffle 12 is opened to the desired position. When the medical staff releases the baffle 12, the elastic potential energy stored in the torsion spring 114 begins to be released. The free end of torsion spring 114 applies a torsional torque to block 1151, driving rotating disk 115 in the opposite direction. Rotating disk 115 then drives baffle 12 in the closing direction. Once baffle 12 rotates to close escape opening 111, torsion spring 114 eventually returns to its initial, unstressed state, ready for the next operation. In this embodiment, storage pockets 117 are provided on both sides of the crib's length to facilitate the storage of nursing supplies.

[0052] In this optional embodiment, the elastic potential energy of the torsion spring 114 is utilized to enable the baffle 12 to automatically reset and close the avoidance opening 111 after the force is eliminated, thereby reducing the manual operation steps of medical staff and improving the convenience and efficiency of operation. This is especially advantageous in some nursing scenarios where the baffle 12 needs to be opened and closed frequently.

[0053] Alternatively, as Figure 2 As shown, it also includes a machine foot assembly 8, which includes a mounting frame 81. The mounting frame 81 is connected to the lower end of the mounting column 4. Casters 82 are connected to the bottom and sides of the mounting frame 81. A storage tray 83 is provided on the mounting frame 81.

[0054] Specifically, the casters 82 in the foot assembly 8 are mounted around the bottom of the mounting frame 81. When the baby basin 11 needs to be moved, a thrust is applied to the baby basin 11, and the casters 82 begin to roll under the force, thereby moving the entire baby basin 11 and the foot assembly 8 together, achieving easy displacement operation. The mounting frame 81 is connected to the lower end of the mounting column 4 and provides support for the entire baby basin 11. The mounting frame 81, through its own structural strength and stability, evenly distributes the weight of the baby basin 11 to each caster 82, ensuring that the baby basin 11 remains stable whether stationary or moving, without tilting or shaking. The storage tray 83 provided on the mounting frame 81 provides additional storage space for medical staff or users. During the process of caring for a baby, some commonly used items such as diapers, wet wipes, and nursing tools can be placed in the storage tray 83 for easy access at any time, improving the efficiency of nursing work.

[0055] In this optional embodiment, the foot assembly 8 integrates the functions of movement, support, and storage, resulting in a compact structure that does not take up too much space. The connection between the mounting bracket 81 and the mounting column 4 is simple and reliable, making it easy to install and remove, and convenient for maintenance and cleaning of the baby basin 11.

[0056] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
