Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a door locking structure for an infant incubator and the infant incubator itself. Background Technology

[0002] As a crucial medical device for neonatal care, the safety and reliability of the incubator's door locking mechanism directly impacts the life safety of the infant inside. In related technologies, incubator doors typically employ a single twist-lock structure to achieve closure between the incubator body and the door. Specifically, this structure usually includes a door that matches the incubator body, and a single twist-lock device is installed between the body and the door, locking and securing the incubator by pressing or rotating.

[0003] However, such locking mechanisms pose significant safety hazards in practical use. Due to busy schedules or negligence on the part of medical staff, the locking mechanism may not be fully pressed or may be forgotten, resulting in a failure to effectively lock the incubator door to the incubator body. If the door is accidentally opened, the infant inside may roll or turn out of the incubator environment, or even fall and suffer serious injury. Utility Model Content

[0004] The problem this utility model solves is: how to avoid the failure of the lock on the box door due to negligence or incomplete pressing by medical staff through structural improvement.

[0005] To solve the above problems, this utility model provides a door locking structure for an infant incubator and an infant incubator.

[0006] In a first aspect, this utility model provides a door locking structure for an infant incubator, including a latch mechanism on the door and a lock hole mechanism on the body. The latch mechanism includes a first lock seat on the outside of the door and a second lock seat on the inside of the door. A first latch is slidably connected to the first lock seat, and an elastic element is provided between the first latch and the first lock seat. A second latch is rotatably connected to the inside of the first latch, and one end of the second latch is rotatably connected to the second lock seat. The lock hole mechanism includes a first lock hole on the outside of the body and a second lock hole on the inside of the body. When extended, the elastic element pushes the first latch into the first lock hole and drives the second latch to rotate and insert into the second lock hole, thus forming a double lock. When compressed, the elastic element drives the first latch out of the first lock hole and drives the second latch to rotate and disengage from the second lock hole, thus unlocking.

[0007] Optionally, the inner side of the first lock seat is provided with a slide rail, which extends to one end near the first lock hole. The first lock tongue is slidably connected to the slide rail, and one end of the first lock tongue can extend out of the slide rail and be inserted into the first lock hole.

[0008] Optionally, the first locking tongue is provided with a strip-shaped groove extending along its sliding direction, and the inner wall of the groove is provided with a mounting boss protruding into the groove, with one end of the mounting boss extending into the strip-shaped groove, one end of the elastic member abutting against the mounting boss, and the other end abutting against the inner wall of the strip-shaped groove near the first locking hole.

[0009] Optionally, a pressing block is connected to the end of the first locking tongue away from the first locking hole. The pressing block extends out of the slide and has a pressing plane perpendicular to the sliding direction. Limiting grooves adapted to the outer surface of the first lock seat are provided on both sides of the pressing plane.

[0010] Optionally, the first lock seat is connected to a limiting block at the end of the slide. When the elastic element is compressed and contracts, causing the first lock tongue to exit the first lock hole, the pressing block abuts against the limiting block to limit the sliding stroke of the first lock tongue.

[0011] Optionally, the pressure-applying surface is provided with a recessed pressing groove.

[0012] Optionally, a connecting block is connected to the inner side of the first latch, and an avoidance hole is provided on the door. The connecting block extends through the avoidance hole to the inner side of the door. A first rotating shaft is provided at one end of the connecting block located on the inner side of the door, and a second rotating shaft is provided on the second latch. The first rotating shaft and the second rotating shaft are connected by a rotating rod. A third rotating shaft is provided on the second lock seat, and the second latch is rotatably connected to the third rotating shaft through a rotating hole.

[0013] Optionally, the rotating rod has an oblong hole corresponding to the first rotating shaft, and the first rotating shaft is rotatably connected to the oblong hole to allow the first rotating shaft to slide in a preset direction within the oblong hole.

[0014] Optionally, the free end of the second latch is provided with a hook-shaped lock head extending toward the second keyhole, the curvature of which is adapted to the inner wall contour of the second keyhole.

[0015] The beneficial effects of the locking structure of the baby incubator door of this utility model are as follows: In the naturally extended state of the elastic element, the elastic element applies a pushing force to the first locking tongue, causing the first locking tongue to insert into the first locking hole on the outside of the incubator body. Since the second locking tongue is rotatably connected to the inside of the first locking tongue, and one end of the second locking tongue is rotatably connected to the second lock seat on the inside of the door, when the first locking tongue is inserted into the first locking hole, it will drive the second locking tongue to rotate, causing the second locking tongue to insert into the second locking hole on the inside of the incubator body, thereby forming a double lock and firmly locking the door and the incubator body. When unlocking is required, pressure is applied to the first locking tongue, causing the elastic element to contract under pressure. The contraction of the elastic element drives the first locking tongue to exit the first locking hole, and at the same time, it drives the second locking tongue to rotate, causing the second locking tongue to disengage from the second locking hole, thus unlocking the door.

[0016] Compared to a single torsion-type locking structure, this invention employs a dual locking method: locking the first locking tongue to the first locking hole and locking the second locking tongue to the second locking hole. This dual locking mechanism significantly reduces the risk of the door and body failing to lock effectively due to busy work or operational negligence by medical staff. Even if the first locking tongue is not fully locked for some reason, the second locking tongue may still provide a certain locking effect, and vice versa, thus effectively preventing the door from being accidentally opened and ensuring the safety of the infant inside. Furthermore, although this invention uses a dual locking design, the operation process is simple: just pressing or releasing the first locking tongue is sufficient to achieve overall locking and unlocking. The operation is relatively simple, eliminating the need for medical staff to perform complex procedures, thus reducing their workload to some extent and minimizing errors caused by complex operations.

[0017] Secondly, this utility model provides an infant incubator, including the aforementioned door locking structure of the infant incubator, and has the beneficial effects of the aforementioned door locking structure of the infant incubator compared with the prior art, which will not be elaborated here.

[0027] like Figure 1 , Figure 2As shown in the figure, the present invention provides a door locking structure for an infant incubator, including a latch mechanism 2 disposed on the door 1 and a lock hole mechanism disposed on the body; the latch mechanism 2 includes a first lock seat 21 disposed on the outside of the door 1 and a second lock seat 22 disposed on the inside of the door 1, a first latch 23 slidably connected to the first lock seat 21, an elastic member 24 disposed between the first latch 23 and the first lock seat 21, a second latch 25 rotatably connected to the inside of the first latch 23, and one end of the second latch 25 rotatably connected to the second lock seat 22; the lock hole mechanism includes a first lock hole disposed on the outside of the body and a second lock hole disposed on the inside of the body; when the elastic member 24 is extended, it pushes the first latch 23 into the first lock hole and drives the second latch 25 to rotate and insert into the second lock hole to form a double lock; when the elastic member 24 is compressed, it drives the first latch 23 out of the first lock hole and drives the second latch 25 to rotate and disengage from the second lock hole to achieve unlocking.

[0028] Specifically, the first lock seat 21 is the basic support component of the latch mechanism 2, fixed on the outside of the door 1, providing an installation position for other components. The second lock seat 22 also serves a supporting function, fixed on the inside of the door 1, and works with the first lock seat 21 to provide a stable environment for the movement of the latch. The first latch 23 is slidably connected to the first lock seat 21, and can slide on the first lock seat 21 to achieve engagement and disengagement with the first lock hole. An elastic element 24 is disposed between the first latch 23 and the first lock seat 21. The elastic element 24 has the characteristics of natural extension and compression contraction. When naturally extended, it provides a thrust to the first latch 23 in the direction of the outside of the door body. When compressed and contracted, it drives the first latch 23 to move inward towards the inside of the door 1. In this embodiment, the elastic element 24 is a spring. The second latch 25 is rotatably connected to the inside of the first latch 23, and can rotate relative to the first latch 23 to achieve engagement and disengagement with the second lock hole. In this embodiment, the second latch 25 is located inside the door 1, and the first latch 23 is located outside the door 1. The first latch 23 passes through the door 1 and extends into the inside of the door 1, where it is rotatably connected to the second latch 25. One end of the second latch 25 is rotatably connected to the second lock seat 22, allowing the second latch 25 to rotate about the connection point with the second lock seat 22 under the influence of the first latch 23. Locking process: In the naturally extended state of the elastic element 24, the elastic element 24 applies a pushing force to the first latch 23, pushing it to move outward toward the outside of the box, so that it is inserted into the first lock hole located on the outside of the box. Since the second latch 25 is rotatably connected to the inside of the first latch 23, and one end of the second latch 25 is rotatably connected to the second lock seat 22 located inside the door 1, when the first latch 23 is inserted into the first lock hole, it will cause the second latch 25 to rotate, so that the second latch 25 is inserted into the second lock hole located inside the box. Thus, through the engagement of the first latch 23 with the first lock hole and the second latch 25 with the second lock hole, a double locking system is formed, firmly securing the door 1 to the cabinet. Unlocking process: When unlocking is required, pressure is applied to the first latch 23, causing the elastic element 24 to contract. The contraction of the elastic element 24 moves the first latch 23 inwards towards the door 1, disengaging it from the first lock hole. Simultaneously, the first latch 23 disengages from the first lock hole, causing the second latch 25 to rotate, disengaging it from the second lock hole, thereby unlocking the door 1 from the cabinet.

[0029] In this embodiment, the traditional single-torsion locking structure poses a safety hazard due to negligence by medical staff, resulting in the door 1 not being effectively locked. However, the locking structure of the infant incubator door 1 in this embodiment employs a dual locking mechanism. Through the cooperation of the first locking tongue 23 with the first lock hole and the second locking tongue 25 with the second lock hole, the reliability of locking the door 1 to the incubator body is greatly increased. Even if one locking method malfunctions for some reason, the other locking method can still provide a secure hold, effectively preventing the door 1 from accidentally opening and causing the infant to leave the incubation environment or even fall and be injured, thus greatly improving the safety of the infant in the incubator. Furthermore, the locking structure in this embodiment achieves automatic locking and linked unlocking through the elastic element 24. When closing the door 1, simply bringing the door 1 close to the incubator body allows the elastic element 24 to naturally extend, pushing the first locking tongue 23 into the first lock hole and causing the second locking tongue 25 to enter the second lock hole, completing the lock without requiring any additional complex operations from medical staff. When unlocking, simply apply pressure to the first locking tongue 23, and the contraction of the elastic element 24 will cause the first locking tongue 23 to exit the first locking hole and the second locking tongue 25 to disengage from the second locking hole. The operation is simple and convenient, reducing the workload of medical staff and also reducing the probability of operational errors caused by complicated operations.

[0030] Optionally, such as Figure 2 , Figure 3 As shown, the inner side of the first lock seat 21 is provided with a slide 211, which extends to the end near the first lock hole. The first lock tongue 23 is slidably connected in the slide 211, and one end of the first lock tongue 23 can extend out of the slide 211 and be inserted into the first lock hole.

[0031] Specifically, a slide rail 211 is provided on the inner side of the first lock seat 21. The slide rail 211 extends to the end near the first lock hole, forming a channel inside the first lock seat 21 for the first latch 23 to slide. One end of the channel extends to the position near the first lock hole, allowing the first latch 23 to approach the first lock hole through the slide rail 211. The first latch 23 is slidably connected to the slide rail 211. When the elastic member 24 extends naturally, the elastic member 24 applies a pushing force to the first latch 23, causing the first latch 23 to slide within the slide rail 211. One end of the first latch 23 can extend out of the slide rail 211 and insert into the first lock hole, achieving initial locking of the door 1 and the box body on the outside of the box body. When unlocking is required, pressure is applied to the first latch 23, causing the elastic member 24 to contract under pressure. The first latch 23 slides away from the first lock hole within the slide rail 211, and the part extending out of the slide rail 211 gradually retracts into the slide rail 211, eventually exiting the first lock hole, completing the unlocking operation.

[0032] In this optional embodiment, the slide rail 211 provides precise guidance for the sliding of the first locking tongue 23. The first locking tongue 23 can only slide within the path specified by the slide rail 211, avoiding deviation or wobbling during the sliding process. This ensures that the first locking tongue 23 can be accurately inserted into the first lock hole, improving the locking accuracy and reliability, and further enhancing the stability of the lock between the door 1 and the body. Furthermore, the slide rail 211 confines the first locking tongue 23 to a specific space, making the connection between the first locking tongue 23 and the first lock seat 21 tighter and more stable. This stable structure can withstand certain external forces, reducing the possibility of accidental movement of the first locking tongue 23 due to external interference (such as vibration of the incubator, accidental contact by medical personnel, etc.), thereby ensuring that the locking structure can work normally in various environments and improving the stability and durability of the entire infant incubator door 1 locking structure. The slide rail 211 also makes the installation of the first locking tongue 23 more convenient. During assembly, the first locking tongue 23 can be simply placed into the slide rail 211, and then the elastic element 24 and other components can be installed, reducing the difficulty of installation and assembly time. At the same time, when maintenance or replacement of the first locking tongue 23 is required, a new first locking tongue 23 can be relatively easily removed from the slide rail 211 and installed, improving the maintainability of the equipment.

[0033] Optionally, such as Figure 2 , Figure 3 , Figure 4 As shown, the first locking tongue 23 has a strip groove 231 extending along its sliding direction. The inner wall of the slide 211 has a mounting boss 212 protruding into the slide 211, and one end of the mounting boss 212 extends into the strip groove 231. One end of the elastic member 24 abuts against the mounting boss 212, and the other end abuts against the inner wall of the strip groove 231 near the first locking hole.

[0034] Specifically, a strip-shaped groove 231 extending along its sliding direction is formed on the first locking tongue 23. A mounting boss 212 protruding into the inner wall of the slide rail 211 is provided, with one end of the mounting boss 212 extending into the strip-shaped groove 231. This allows the strip-shaped groove 231 to move along the mounting boss 212 as the first locking tongue 23 slides within the slide rail 211. The mounting boss 212 acts as a guide, ensuring that the first locking tongue 23 can only move along a predetermined sliding direction, preventing it from deviating or wobbling. One end of the elastic element 24 abuts against the mounting boss 212, and the other end abuts against the inner wall of the strip-shaped groove 231 near the first locking hole. When the door 1 is closed, the elastic element 24 is in its naturally extended state. Due to the abutment of the mounting boss 212 and the inner wall of the strip groove 231 at both ends of the elastic element 24, a pushing force is applied to the first latch 23 towards the first lock hole, causing the first latch 23 to slide within the slide rail 211 and extend out of the slide rail 211 to insert into the first lock hole, thus locking. When unlocking is required, pressure is applied to the first latch 23, causing it to slide away from the first lock hole within the slide rail 211. The strip groove 231 moves relative to the mounting boss 212, and the elastic element 24 is compressed and contracts. When the pressure disappears, the elastic element 24 returns to its naturally extended state, pushing the first latch 23 back into the first lock hole.

[0035] In this optional embodiment, the mating structure of the mounting boss 212 and the strip groove 231 provides more precise guidance for the sliding of the first locking tongue 23. Compared to relying solely on the inner wall of the groove 211 to restrict the sliding direction, it can more effectively prevent the first locking tongue 23 from skewing or getting stuck during sliding, making the sliding of the first locking tongue 23 more stable and smooth, thereby improving the stability and reliability of the entire locking structure. Furthermore, the mounting boss 212 and the inner wall of the strip groove 231 provide a stable mounting position for the elastic element 24, enabling the elastic element 24 to accurately apply thrust or contraction force. This ensures that the elastic element 24 can uniformly transmit force during the force application process, reducing problems such as damage to the elastic element 24 and locking failure caused by unstable installation or uneven force, extending the service life of the elastic element 24, and improving the durability of the locking structure. Moreover, it achieves the sliding guidance of the first locking tongue 23 and the installation of the elastic element 24 within a limited space. The mounting boss 212 and the strip groove 231 have a compact structure that does not take up too much space between the door 1 and the box body. This is conducive to the miniaturization of the overall structure of the infant incubator and does not affect the layout and installation of other components, thus improving the integration and space utilization of the equipment.

[0036] Optionally, such as Figure 2 , Figure 4As shown, the end of the first locking tongue 23 away from the first locking hole is connected to a pressing block 232. The pressing block 232 extends out of the slide 211 and has a pressing plane 2321 perpendicular to the sliding direction. The pressing plane 2321 has limiting grooves 2322 on both sides that are adapted to the outer surface of the first locking seat 21.

[0037] Specifically, a pressing block 232 is connected to the end of the first locking tongue 23 away from the first keyhole. The pressing block 232 extends into a slide 211, allowing medical personnel to operate the pressing block 232 directly from outside the slide 211. The pressing block 232 has a pressure-applying surface 2321 perpendicular to the sliding direction. When unlocking is required, medical personnel only need to apply pressure to the pressure-applying surface 2321. The pressure is transmitted to the first locking tongue 23 through the pressing block 232, causing the first locking tongue 23 to slide away from the first keyhole within the slide 211. The elastic element 24 contracts under pressure, causing the first locking tongue 23 to exit the first keyhole and simultaneously causing the second locking tongue 25 to rotate and disengage from the second keyhole, thereby achieving unlocking. The pressure surface 2321 has limiting grooves 2322 on both sides that are adapted to the outer surface of the first lock seat 21. When the first lock tongue 23 is normally in the locked state (i.e., the elastic element 24 is naturally extended and the first lock tongue 23 is inserted into the first lock hole), the limiting grooves 2322 engage with the outer surface of the first lock seat 21, which plays a certain limiting role on the pressing block 232, preventing the pressing block 232 from moving along the slide 211 to the inside of the door 1, avoiding the pressing block 232 from falling out from the inside of the slide 211, ensuring the stability of the first lock tongue 23 in the slide 211, and thus ensuring the reliability of the locking structure.

[0038] In this optional embodiment, the pressing block 232 extends into a slide 211 and is provided with a pressure-applying surface 2321, providing a clear operating point for medical personnel. Medical personnel do not need to perform complex operations inside the slide 211; they only need to apply pressure to the pressure-applying surface 2321 from the outside of the slide 211 to unlock the device. This makes the operation more convenient and faster, improving work efficiency, and is especially suitable for busy scenarios where medical personnel are working. The pressure-applying surface 2321 is perpendicular to the sliding direction, allowing the pressure applied by the medical personnel to be transmitted more directly and effectively to the first locking tongue 23, reducing losses and deviations during pressure transmission, ensuring that the first locking tongue 23 can slide in the expected direction and with the expected force, thus improving the stability and reliability of unlocking. The limiting slots 2322 on both sides of the pressure surface 2321 are adapted to the outer surface of the first lock seat 21. In the locked state, they can limit and fix the pressing block 232, effectively preventing the pressing block 232 from moving along the slide 211 to the inside of the door 1 and avoiding the pressing block 232 from falling out from the inside of the slide 211. This ensures that the first locking tongue 23 is in a stable position in the slide 211, avoids locking failure caused by accidental movement of the first locking tongue 23, and improves the stability and safety of the entire infant incubator door 1 locking structure.

[0039] Optionally, such as Figure 2 , Figure 3 As shown, the first lock seat 21 is located at the end of the slide 211 and connected to the limit block 213. When the elastic member 24 is compressed and contracts, and drives the first lock tongue 23 to exit the first lock hole, the pressing block 232 abuts against the limit block 213 to limit the sliding stroke of the first lock tongue 23.

[0040] Specifically, when unlocking is required, medical personnel apply pressure to the pressing block 232. This pressure is transmitted through the pressing block 232 to the first locking tongue 23, causing the first locking tongue 23 to slide away from the first keyhole within the slide rail 211. Simultaneously, the elastic element 24 contracts under pressure. As the first locking tongue 23 continues to slide, when the elastic element 24 contracts to a certain extent and the first locking tongue 23 is about to completely exit the first keyhole, the limiting block 213 connected to the end of the slide rail 211 of the first lock seat 21 comes into play. At this time, the pressing block 232 abuts against the limiting block 213. Due to the obstruction of the limiting block 213, the first locking tongue 23 cannot continue to slide away from the first keyhole, thus limiting the sliding stroke of the first locking tongue 23 and preventing the first locking tongue 23 from dislodging from the slide rail 211 due to excessive sliding or causing damage to other components.

[0041] In this optional embodiment, the limiting block 213 effectively restricts the sliding stroke of the first locking tongue 23, preventing it from slipping out of the slide rail 211 during unlocking. If the first locking tongue 23 slips out of the slide rail 211, it may damage the entire locking structure, affecting the normal use of the incubator and potentially threatening the safety of the infant inside. The limiting block 213 prevents this from happening, protecting the first locking tongue 23, the slide rail 211, and other related components. Furthermore, by limiting the sliding stroke of the first locking tongue 23, the limiting block 213 ensures the stability of the locking structure during unlocking and locking. During unlocking, the first locking tongue 23 can slide within a limited range, making the unlocking action smoother and more reliable. During locking, the presence of the limiting block 213 does not affect the normal reset and locking function of the first locking tongue 23, thus ensuring the long-term stable operation of the entire incubator door 1 locking structure. It also avoids damage to components caused by excessive sliding of the first locking tongue 23, reducing the frequency of equipment maintenance and replacement, and lowering operating costs. At the same time, a stable structure also helps to extend the lifespan of the entire infant incubator, improving the cost-effectiveness of the equipment.

[0042] Optionally, such as Figure 4 As shown, the pressure surface 2321 is provided with a recessed pressing groove 2323.

[0043] Specifically, when it is necessary to unlock the infant incubator door 1, medical staff need to apply pressure to the pressure surface 2321 on the pressing block 232. The pressure surface 2321 has a recessed pressing groove 2323, into which medical staff can place their fingers or other operating tools. Due to the presence of the pressing groove 2323, the fingers or operating tools can be positioned more accurately on the pressure surface 2321, and the recessed structure makes the contact between the fingers or operating tools and the pressure surface 2321 more compact and stable. When pressure is applied, the pressure can be transmitted more directly and effectively to the pressing block 232, thereby driving the first locking tongue 23 to slide away from the first locking hole in the slide 211, and the elastic element 24 is compressed and contracted, ultimately realizing the unlocking operation.

[0044] In this optional embodiment, the recessed pressing groove 2323 provides medical personnel with a clear operating positioning point. During the unlocking process, medical personnel do not need to spend time finding a suitable position to apply force; they only need to place their fingers in the pressing groove 2323 to accurately apply pressure to the pressure surface 2321, greatly improving the accuracy of operation and reducing the possibility of unlocking failure or damage to the device due to operational errors. Furthermore, the recessed pressing groove 2323 increases the friction and contact area between the finger or operating tool and the pressure surface 2321, making the force application process more stable. When applying pressure, the finger or operating tool is less likely to slip, and the pressure can be continuously and stably transmitted to the pressing block 232, ensuring that the first locking tongue 23 can slide in the expected manner, improving the stability and reliability of unlocking. Moreover, from an ergonomic point of view, the recessed pressing groove 2323 is more in line with the hand operating habits of medical personnel. When using it, medical staff can naturally place their fingers into the press slot 2323, reducing hand fatigue and improving operating comfort. This design can significantly improve the working experience of medical staff, especially when frequent unlocking operations are required.

[0045] Optionally, such as Figure 2 , Figure 4 As shown, a connecting block 233 is connected to the inner side of the first latch 23, and an avoidance hole 11 is provided on the door 1. The connecting block 233 extends through the avoidance hole 11 to the inner side of the door 1. A first rotating shaft 2331 is provided at one end of the connecting block 233 located on the inner side of the door 1. A second rotating shaft 251 is provided on the second latch 25. The first rotating shaft 2331 and the second rotating shaft 251 are connected by a rotating rod 26. A third rotating shaft 221 is provided on the second lock seat 22. The second latch 25 is rotatably connected to the third rotating shaft 221 through a rotating hole.

[0046] Specifically, when unlocking is required, medical personnel apply pressure to the pressing block 232, causing the first locking tongue 23 to slide away from the first lock hole within the slide rail 211. Since a connecting block 233 is connected to the inner side of the first locking tongue 23, and the connecting block 233 extends through the clearance hole 11 on the door 1 to the inner side of the door 1, the sliding of the first locking tongue 23 will cause the connecting block 233 to move synchronously. A first rotating shaft 2331 is provided at one end of the connecting block 233 located on the inner side of the door 1, and a second rotating shaft 251 is provided on the second locking tongue 25. The first rotating shaft 2331 and the second rotating shaft 251 are connected by a rotating rod 26. When the connecting block 233 moves, the first rotating shaft 2331 moves accordingly, which in turn drives the second rotating shaft 251 to rotate via the rotating rod 26. The rotation of the second rotating shaft 251 causes the second locking tongue 25 to rotate around its connection point with the second lock seat 22. The second lock seat 22 is provided with a third rotating shaft 221. The second lock tongue 25 is rotatably connected to the third rotating shaft 221 through a rotating hole, which allows the second lock tongue 25 to rotate around the third rotating shaft 221 as its axis. During the sliding unlocking process of the first lock tongue 23, the second lock tongue 25 rotates under the drive of the rotating rod 26, thereby disengaging from the second lock hole and unlocking the door 1. When locking is required, the elastic element 24 pushes the first lock tongue 23 into the first lock hole, while simultaneously driving the connecting block 233 to move in the opposite direction. The rotating rod 26 causes the second lock tongue 25 to rotate in the opposite direction and insert into the second lock hole, completing the locking.

[0047] In this optional embodiment, the linkage between the first locking tongue 23 and the second locking tongue 25 is achieved through the structure of the connecting block 233, the rotating rod 26, and the first rotating shaft 2331, the second rotating shaft 251, and the third rotating shaft 221. Simply applying pressure to the first locking tongue 23 to unlock it will cause the second locking tongue 25 to automatically rotate and disengage from the second lock hole, and vice versa. This linkage design simplifies the operation process, eliminating the need for medical personnel to operate the two locking tongues separately, thus improving convenience and efficiency. Furthermore, by utilizing the clearance hole 11 on the door 1 and the cooperation of each rotating shaft and rotating rod 26, the linkage structure is integrated inside the door 1, minimizing the space occupied outside the door 1 and making the entire infant incubator structure more compact. Simultaneously, the connection and rotation methods between the components are stable and reliable, ensuring the normal operation of the locking and unlocking functions and reducing problems such as locking failure or unlocking difficulties caused by structural instability. Furthermore, the installation of each component is relatively independent and simple. The first locking tongue 23, connecting block 233, rotating rod 26, and other components can be assembled on one side of the door 1 first. Then, the second locking tongue 25 is connected to the third rotating shaft 221 on the second lock seat 22 through the rotating hole. Finally, the entire structure is installed onto the door 1 and the box body. During maintenance, it is also convenient to inspect, replace, and repair each component, reducing maintenance costs and difficulty.

[0048] Optionally, such as Figure 2As shown, a waist-shaped hole 261 is provided on the rotating rod 26 corresponding to the first rotating shaft 2331. The first rotating shaft 2331 is rotatably connected to the waist-shaped hole 261 so as to allow the first rotating shaft 2331 to slide in the waist-shaped hole 261 in a preset direction.

[0049] Specifically, during the unlocking operation, medical personnel apply pressure to the pressing block 232, causing the first locking tongue 23 to slide away from the first lock hole within the slide rail 211, thus moving the connecting block 233 and consequently causing the first rotating shaft 2331 to move as well. Since the rotating rod 26 has a waist-shaped hole 261 corresponding to the first rotating shaft 2331, and the first rotating shaft 2331 is rotatably connected within the waist-shaped hole 261, the first rotating shaft 2331 can slide along a preset direction within the waist-shaped hole 261 during movement. Simultaneously, the movement of the first rotating shaft 2331 causes the rotating rod 26 to rotate around the second rotating shaft 251 (because the second rotating shaft 251 is relatively fixed in position and connected to the second locking tongue 25). The rotation of the rotating rod 26 further causes the second locking tongue 25 to rotate around the third rotating shaft 221, disengaging the second locking tongue 25 from the second lock hole and achieving unlocking. During the locking process, the elastic element 24 pushes the first locking tongue 23 into the first lock hole, the first rotating shaft 2331 moves in the opposite direction and slides in the waist-shaped hole 261 in a preset direction, and drives the second locking tongue 25 to rotate in the opposite direction and insert into the second lock hole through the rotating rod 26, thus completing the locking.

[0050] In this optional embodiment, the oblong hole 261 allows the first rotating shaft 2331 to slide along a preset direction on the rotating rod 26. This allows the relative position between the first rotating shaft 2331 and the rotating rod 26 to change during the sliding of the first locking tongue 23, thereby enhancing the flexibility of the entire linkage structure. During the unlocking and locking process, even if there are certain manufacturing errors or installation deviations between the components, the oblong hole 261 can play a certain compensating role, ensuring that the linkage action can be carried out smoothly and reducing the situation of jamming or failure to unlock / lock normally due to inaccurate component matching. Moreover, the sliding of the first rotating shaft 2331 in the oblong hole 261 can better adapt to the movement trajectory of the first locking tongue 23, enabling the rotating rod 26 to more efficiently convert the linear motion of the first locking tongue 23 into the rotational motion of the second locking tongue 25. This can reduce energy loss, improve the response speed of unlocking and locking operations, and enable medical staff to complete the opening and closing operation of the door 1 more easily and quickly. Furthermore, during the use of the infant incubator, various reasons (such as deformation of the door 1, wear of components, etc.) may cause changes in the relative positions of the components of the locking structure. The presence of the oblong hole 261 gives the connection between the rotating rod 26 and the first rotating shaft 2331 a certain degree of fault tolerance, enabling it to adapt to these changes, ensuring the long-term stable operation of the locking structure, and extending the service life of the equipment.

[0051] Optionally, such as Figure 2As shown, the free end of the second latch 25 is provided with a hook-shaped lock head 252 extending toward the second lock hole, and the curvature of the hook-shaped lock head 252 is adapted to the inner wall contour of the second lock hole.

[0052] Specifically, during the locking operation, as the elastic element 24 pushes the first locking tongue 23 into the first keyhole, the linkage structure (such as the connecting block 233, the rotating rod 26, and various rotating shafts) drives the second locking tongue 25 to rotate around the third rotating shaft 221. The hook-shaped lock head 252 at the free end of the second locking tongue 25 then moves towards the second keyhole. Because the curvature of the hook-shaped lock head 252 matches the contour of the inner wall of the second keyhole, it fits tightly against the inner wall of the second keyhole after entering, forming a stable locking state. When unlocking is required, medical personnel apply pressure to the pressing block 232, causing the first locking tongue 23 to slide away from the first keyhole within the slide rail 211. The linkage structure then drives the second locking tongue 25 to rotate in the opposite direction, disengaging the hook-shaped lock head 252 from the second keyhole, thus unlocking the device.

[0053] In this optional embodiment, the curvature of the hook-shaped lock head 252 is adapted to the inner wall contour of the second lock hole, so that after the hook-shaped lock head 252 enters the second lock hole, it can form multiple points of tight contact and engagement with the inner wall of the second lock hole. This close-fitting locking method greatly increases the friction and engagement force between the second locking tongue 25 and the second lock hole, effectively preventing the door 1 from being accidentally opened due to vibration, external force or other factors during normal use, improving the stability and reliability of the locking of the infant incubator door 1, and ensuring the safety of the infant inside the incubator.

[0054] This utility model provides an infant incubator, including the door locking structure of the infant incubator as described above.

[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
