Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a locking component, a connecting mechanism, and an anesthesia machine. Background Technology

[0002] During the operation of anesthesia machines, the oxygen cell, as a key component for monitoring the oxygen concentration in the output gas, requires regular calibration, replacement, or maintenance to ensure its detection accuracy and the safe operation of the anesthesia machine. To facilitate operation of the oxygen cell, anesthesia machines typically have an openable cover at the installation location. This cover is locked to the main body of the anesthesia machine via a locking mechanism to prevent accidental opening during machine operation, which could lead to the oxygen cell detaching, gas leakage, or the intrusion of external contaminants.

[0003] In existing technologies, traditional latches mostly adopt a single-direction unlocking design. This single-direction design is prone to incomplete locking during the latching process due to the limited direction of force applied, affecting the stability of the connection between the door cover and the main body of the anesthesia machine, and causing inconvenience for the daily maintenance of the oxygen battery. Utility Model Content

[0004] The technical problem this application aims to solve is that, in the existing technology, traditional latches mostly adopt a single-direction unlocking design. This single-direction design is prone to incomplete locking during the latching process due to the limited direction of force application, affecting the stability of the connection between the door cover and the main body of the anesthesia machine, and causing inconvenience to the daily maintenance of the oxygen battery. This application provides a locking component, a connecting mechanism, and an anesthesia machine.

[0005] To address the aforementioned issues, this application provides a locking assembly, including a push rod, a locking rod, and a lock seat. The lock seat is adapted to be fixedly mounted on the door cover of an anesthesia machine. Both the push rod and the locking rod are adapted to be mounted on the main body of the anesthesia machine. The push rod is adapted to be movably connected to the main body along a first direction, and the locking rod is adapted to be movably connected to the main body along a second direction. The locking rod is kinetically connected to the push rod, and the locking rod can be temporarily inserted into the lock seat to lock the door cover to the main body. When the locking rod is inserted into the lock seat, pushing the push rod to move in the first direction can drive the locking rod to move in the second direction, so that the locking rod can be removed from the lock seat and the door cover can be unlocked; wherein, the first direction is perpendicular to the second direction.

[0006] Optionally, the locking rod is provided with a first guide groove on the side facing the push rod, and the first guide groove has a first guide surface on an inner sidewall in the second direction, and the first guide surface extends along the first direction and the second direction; A portion of the push rod's structure contacts the first guide surface. When the push rod is pushed to move in the first direction, the push rod pushes the locking rod to move in the second direction via the first guide surface.

[0007] Optionally, the push rod is provided with a second guide groove on the side facing the locking rod, the second guide groove corresponds to the first guide groove, and the second guide groove has a second guide surface on an inner sidewall in the first direction, the second guide surface extending along the first direction and the second direction; The first guide surface and the second guide surface are in contact. When the first guide surface is pushed to move in the first direction, the first guide surface and the second guide surface can move relative to each other, so that the locking rod can move in the second direction.

[0008] Optionally, the main body of the anesthesia machine is provided with a mounting base, the mounting base is provided with a first slide groove and a second slide groove, the first slide groove extends along the first direction, the second slide groove extends along the second direction, the push rod is slidably connected to the first slide groove, and the locking rod is slidably connected to the second slide groove.

[0009] Optionally, the locking assembly further includes a first elastic element disposed in the second slide groove, the locking rod and the first elastic element being arranged sequentially along the second direction, and the first elastic element abutting against the locking rod and an inner wall of the second slide groove along the second direction; The first elastic element has a tendency to drive the locking rod away from an inner wall of the second groove along the second direction, and pushing the push rod to move along the first direction can drive the locking rod to overcome the elasticity of the first elastic element and move along the second direction.

[0010] Optionally, the locking assembly further includes a second elastic element disposed in the first slide groove, the push rod and the second elastic element are arranged sequentially along the first direction, and the second elastic element abuts against the push rod and an inner wall of the first slide groove along the first direction; The second elastic element has a tendency to drive the push rod away from an inner wall of the first groove along the first direction, pushes the push rod and overcomes the elastic force of the second elastic element, so that the push rod moves toward an inner wall of the first groove along the first direction.

[0011] Optionally, a pressing portion is provided at the end of the push rod away from the second elastic element, and the cross-sectional area of ​​the pressing portion is larger than the cross-sectional area of ​​the push rod along the first direction.

[0012] According to the locking assembly provided in this application embodiment, the lock seat is fixed to the door cover of the anesthesia machine, while the push rod and locking rod are installed on the main body of the anesthesia machine. The push rod can move along a first direction, and the locking rod can move along a second direction perpendicular to the first direction, and the two maintain a transmission connection. When the door cover is closed, the locking rod is temporarily inserted into the lock seat, and the door cover is stably locked to the main body through the mechanical insertion and engagement. When unlocking is required, the push rod is pushed along the first direction, and the push rod drives the locking rod to move along the second direction through the transmission structure, causing the locking rod to disengage from the lock seat, thereby releasing the locked state between the door cover and the main body. The locking assembly of this application effectively solves the problem of incomplete locking in traditional single-direction locks. Through the vertical transmission design of the push rod and locking rod, the flexibility of force application is expanded, the risk of unstable locking caused by the limitation of the force application direction is reduced, and the stability of the connection between the door cover and the main body of the anesthesia machine is significantly improved. Meanwhile, the unlocking operation can be achieved simply by pushing the lever in the first direction, which simplifies the operation process and makes the daily calibration, replacement or maintenance of oxygen cells more convenient and efficient. This further ensures the stability of oxygen cell installation during the operation of the anesthesia machine and reduces safety hazards such as oxygen cell detachment, gas leakage or contaminant intrusion caused by accidental opening of the door cover.

[0013] This application provides a connection mechanism including a door cover of an anesthesia machine, a main body of the anesthesia machine, and the aforementioned locking assembly. The main body is provided with a accommodating compartment, which is adapted to house an oxygen cell. The accommodating compartment has an opening on one side along a third direction. The door cover is rotatably connected to the main body about a first axis and can open or close the opening. The lock seat is fixedly disposed on the door cover. The push rod and the locking rod are both adapted to be disposed on the main body of the anesthesia machine. The push rod is adapted to be movably connected to the main body along a first direction, and the locking rod is adapted to be movably connected to the main body along a second direction. When the door cover closes the opening, the locking rod can be inserted into the lock seat. The extension direction of the first axis is parallel to the first direction, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0014] Optionally, the connecting mechanism further includes a third elastic element connected between the body and the door cover, the third elastic element having a tendency to drive the door cover to open the opening.

[0015] According to the connection mechanism provided in this application embodiment, the main body's accommodating compartment is used to hold oxygen batteries. It has an opening on one side along a third direction. The door cover can rotate around a first axis parallel to the first direction, thereby opening or closing the opening. When the door cover closes the opening, the lock seat fixed on the door cover corresponds to the locking rod on the main body. The locking rod moves along a second direction and inserts into the lock seat, securing the door cover firmly to the main body through the mechanical locking structure of the locking assembly. When unlocking, a push rod on the main body is pushed along the first direction. The push rod, through transmission, drives the locking rod to move along the second direction and exit the lock seat. The door cover can then rotate around the first axis to open the opening, facilitating operation of the oxygen batteries in the accommodating compartment. This connection mechanism, through its three-dimensional vertical spatial layout and push rod-locking rod vertical transmission design, breaks the limitation of single-direction unlocking. It significantly reduces the risk of incomplete locking and significantly improves the connection stability between the door cover and the main body. Simultaneously, the unlocking operation direction is adapted to the door cover opening and closing logic, avoiding operational jamming and making the door cover opening and closing smoother during oxygen battery maintenance, effectively reducing maintenance inconvenience and ensuring the safe operation of the anesthesia machine.

[0016] An anesthesia machine provided in this application includes an oxygen cell and the above-mentioned connection mechanism, wherein the oxygen cell is disposed in the accommodating chamber.

[0017] The anesthesia machine provided according to the embodiments of this application includes the aforementioned connecting mechanism and an oxygen cell disposed within the accommodating chamber, effectively solving the chain reaction caused by traditional locking mechanisms. Through the three-dimensional vertical spatial layout of the connecting mechanism and the vertical transmission design of the push rod-locking rod, the stability of the connection between the door cover and the main body is significantly improved, avoiding the risk of the oxygen cell loosening or falling out within the accommodating chamber due to inadequate locking, ensuring the accuracy of oxygen concentration monitoring, and improving the safety and reliability of the anesthesia machine's operation.

[0021] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] like Figures 1 to 8 As shown, one embodiment of this application provides a locking assembly 1, including a push rod 11, a locking rod 12, and a lock seat 13. The lock seat 13 is adapted to be fixedly installed on the door cover 2 of an anesthesia machine. Both the push rod 11 and the locking rod 12 are adapted to be installed on the main body of the anesthesia machine. The push rod 11 is adapted to be movably connected to the main body in a first direction, and the locking rod 12 is adapted to be movably connected to the main body in a second direction. The locking rod 12 is convexly connected to the push rod 11, and the locking rod 12 can be temporarily inserted into the lock seat 13 to lock the door cover 2 to the main body. When the locking rod 12 is inserted into the lock seat 13, pushing the push rod 11 to move in the first direction can drive the locking rod 12 to move in the second direction, so that the locking rod 12 can exit the lock seat 13 and release the lock on the door cover 2; wherein, the first direction is perpendicular to the second direction. In this embodiment, the first direction is the second direction. Figure 1 The X direction in the middle, the second direction is attached. Figure 1In the Y direction, the movement direction of the push rod 11 (or button) is highly consistent with the movement direction of the locking rod 12 (or latch). For example, if the push rod 11 is pushed horizontally (e.g., forward), the locking rod 12 will also move in the same horizontal direction (or the opposite direction), directly completing the locking or unlocking. Due to the limitations of the force direction, if the force angle is slightly off or the force is insufficient during engagement, the locking may not be fully engaged, affecting the stability of the connection between the door cover 2 and the main body of the anesthesia machine, and causing inconvenience to the daily maintenance of the oxygen battery. Specifically, in the traditional single-direction design, the push rod 11 and the locking rod 12 move in the same direction. If the force angle is slightly off during engagement (e.g., the pushing direction deviates from the axis of the locking rod 12), the force will be distributed to the non-locking direction, which may cause the locking rod 12 to not be fully inserted into the lock seat 13. In this solution, the first direction (the direction of force application of the push rod 11) is perpendicular to the second direction (the direction of insertion of the locking rod 12). When force is applied, the force of the push rod 11 is converted into a stable driving force of the locking rod 12 along the second direction through the transmission structure. Even if the angle of force application of the push rod 11 is slightly deviated, the vertical transmission structure can filter out the ineffective component force, ensuring that the locking rod 12 accurately inserts into the lock seat 13 along the preset second direction, thereby reducing the problem of incomplete locking caused by angle deviation. Specifically, the locking assembly 1 of this application effectively solves the drawbacks of the traditional single-direction unlocking design through the vertical transmission design of the push rod 11 and the locking rod 12. The vertical layout of the first and second directions breaks the limitation of the direction of force application. When locking, the action of the locking rod 12 inserting into the lock seat 13 along the second direction is more stable, reducing the problem of incomplete locking caused by the angle deviation of force application, and significantly improving the stability of the connection between the door cover 2 and the main body. Meanwhile, when unlocking, simply pushing the push rod 11 in the first direction will drive the locking rod 12 to exit the lock seat 13 in the second direction, making the operation of the door cover 2 during routine maintenance of the oxygen battery more convenient and fundamentally reducing equipment safety hazards caused by lock problems.

[0025] like Figure 6 and Figure 7 As shown, in one embodiment, the lock base 13 is provided with a slot 131, into which the locking rod 12 can be inserted.

[0026] like Figure 7 and Figure 8 As shown, in one embodiment, the locking rod 12 is provided with a first guide groove 121 on the side facing the push rod 11. The first guide groove 121 has a first guide surface 1211 on an inner sidewall in the second direction. The first guide surface 1211 extends along the first direction and the second direction. Part of the push rod 11 contacts the first guide surface 1211. When the push rod 11 is pushed to move in the first direction, it pushes the locking rod 12 to move in the second direction via the first guide surface 1211. The first guide surface 1211 of the first guide groove 121 provides precise guidance for the transmission between the push rod 11 and the locking rod 12, ensuring that the force of the push rod 11 in the first direction is stably converted into the movement of the locking rod 12 in the second direction. This reduces force loss and offset during transmission, making the action of the locking rod 12 inserting into or withdrawing from the lock seat 13 smoother and more precise, further reducing the risk of incomplete locking and improving operational reliability.

[0027] like Figures 6-8 As shown, in one embodiment, the push rod 11 is provided with a second guide groove 111 on the side facing the locking rod 12. The second guide groove 111 corresponds to the first guide groove 121. The inner sidewall of the second guide groove 111 in the first direction has a second guide surface 1111. The second guide surface 1111 extends along the first direction and the second direction. The first guide surface 1211 and the second guide surface 1111 are in contact. When the pusher moves along the first direction, the first guide surface 1211 and the second guide surface 1111 can move relative to each other, allowing the locking rod 12 to move along the second direction. The second guide surface 1111 of the second guide groove 111 is in contact with the first guide surface 1211, further optimizing the force transmission path. When the second guide surface 1111 and the first guide surface 1211 move relative to each other, the force of the push rod 11 in the first direction can be converted into the power of the locking rod 12 in the second direction more stably, reducing transmission jamming and deviation, making the locking rod 12 move more accurately and smoothly, and greatly improving the reliability of locking and unlocking.

[0028] like Figures 3-6 As shown, in one embodiment, the main body of the anesthesia machine is provided with a mounting base 14. The mounting base 14 is provided with a first sliding groove 141 and a second sliding groove 142. The first sliding groove 141 extends along a first direction, and the second sliding groove 142 extends along a second direction. The push rod 11 is slidably connected to the first sliding groove 141, and the locking rod 12 is slidably connected to the second sliding groove 142. The first sliding groove 141 and the second sliding groove 142 of the mounting base 14 provide directional sliding tracks for the push rod 11 and the locking rod 12, respectively, restricting them to move only along the first and second directions, and avoiding deviation or shaking during transmission. This further ensures the stability and accuracy of force transmission, making the insertion and withdrawal of the locking rod 12 into and out of the locking seat 13 more reliable, and improving the overall operational stability of the locking assembly 1.

[0029] like Figure 4As shown, in one embodiment, the locking assembly 1 further includes a first elastic member 15, which is disposed in the second slide groove 142. The locking rod 12 and the first elastic member 15 are arranged sequentially along the second direction, and the first elastic member 15 abuts against the locking rod 12 and an inner wall of the second slide groove 142 along the second direction. The first elastic element 15 tends to drive the locking rod 12 away from the inner wall of the second slide groove 142 along a second direction. Pushing the push rod 11 to move along the first direction can drive the locking rod 12 to overcome the elasticity of the first elastic element 15 and move along the second direction. By continuously applying elastic force, the first elastic element 15 always drives the locking rod 12 to maintain the tendency to move towards the lock seat 13, ensuring that the locking rod 12 can automatically and accurately insert into the lock seat 13 when the door cover 2 is closed, avoiding incomplete locking due to insufficient manual operation force. When unlocking, the push rod 11 drives the locking rod 12 to move against the elastic force. After releasing the push rod 11, the elastic force can drive the locking rod 12 to automatically reset, improving the reliability and ease of operation of the locking action, and further ensuring the stability of the door cover 2 locking.

[0030] like Figure 7 As shown, in one embodiment, a first limiting hole 122 is provided at one end of the locking rod 12 near the inner wall of the second slide groove 142 along the second direction, and one end of the first elastic member 15 near the locking rod 12 is installed in the first limiting hole 122. The first limiting hole 122 is a blind hole and extends along the second direction. This facilitates the limitation of the position of the first elastic member 15, effectively ensuring the elastic function of the first elastic member 15.

[0031] like Figure 4 As shown, in one embodiment, the locking assembly 1 further includes a second elastic member 16, which is disposed in the first slide groove 141. The push rod 11 and the second elastic member 16 are arranged sequentially along the first direction, and the second elastic member 16 abuts against the push rod 11 and an inner wall of the first slide groove 141 along the first direction. The second elastic element 16 tends to drive the push rod 11 away from the inner wall of the first groove 141 along the first direction, pushing the push rod 11 and overcoming the elastic force of the second elastic element 16, causing the push rod 11 to move towards the inner wall of the first groove 141 along the first direction. By continuously applying elastic force, the second elastic element 16 drives the push rod 11 to maintain its initial position away from the inner wall of the first groove 141, ensuring that the push rod 11 is in a stable state before the unlocking operation. Here, "initial position" refers to the stable position of the push rod 11 under the elastic force of the second elastic element 16 when it is not pushed by an external force. During unlocking, the push rod 11 is pushed to overcome the elastic force and moves. After releasing the push rod 11, the elastic force can automatically reset the push rod 11 to its initial position, preventing the push rod 11 from deviating from its original position due to residual external force or vibration, ensuring the accuracy of the next locking operation, and simplifying the reset process after unlocking, thus improving the overall convenience and reliability of the operation. Understandably, when locking is required, push rod 11 is first pushed along the first direction. Push rod 11 overcomes the elastic force of the second elastic element 16 and moves towards the inner wall of the first slide groove 141. At the same time, through the transmission structure, locking rod 12 overcomes the elastic force of the first elastic element 15 and moves along the second direction, causing locking rod 12 to retract to a position that does not obstruct the closing of door cover 2. At this time, door cover 2 is closed, and lock seat 13 on door cover 2 rotates with door cover 2 to the position corresponding to locking rod 12. Then, push rod 11 is released, and the pushing force of push rod 11 on locking rod 12 disappears; the first elastic element 15 and the second elastic element 16 release their elastic force simultaneously, driving locking rod 12 to move in the opposite direction along the second direction, accurately inserting into lock seat 13, completing the locking of door cover 2 and main body. Throughout the process, the elastic force of the elastic elements ensures the accuracy and stability of the reset of push rod 11 and locking rod 12, achieving reliable locking without additional manual adjustment, simplifying the operation steps and improving locking efficiency.

[0032] like Figure 8 As shown, in one embodiment, a second limiting hole 113 is provided at one end of the push rod 11 near the inner wall of the first slide groove 141 along the first direction, and one end of the second elastic member 16 near the push rod 11 is installed in the second limiting hole 113. The second limiting hole 113 is a blind hole and extends along the first direction. This facilitates the limitation of the position of the second elastic member 16, effectively ensuring the elastic function of the second elastic member 16.

[0033] like Figure 6 As shown, in one embodiment, a pressing portion 112 is provided at the end of the push rod 11 away from the second elastic member 16. Along the first direction, the cross-sectional area of ​​the pressing portion 112 is larger than the cross-sectional area of ​​the push rod 11. Providing a pressing portion 112 with a larger cross-sectional area at the end of the push rod 11 away from the second elastic member 16 can significantly improve the convenience of the unlocking operation.

[0034] According to the locking assembly 1 provided in this application embodiment, the lock seat 13 is fixed to the door cover 2 of the anesthesia machine, and the push rod 11 and the locking rod 12 are installed on the main body of the anesthesia machine. The push rod 11 can move along a first direction, and the locking rod 12 can move along a second direction perpendicular to the first direction, and the two are connected by transmission. When the door cover 2 is closed, the locking rod 12 is temporarily inserted into the lock seat 13, and the door cover 2 is stably locked to the main body through the mechanical insertion and engagement. When unlocking is required, the push rod 11 is pushed along the first direction, and the push rod 11 drives the locking rod 12 to move along the second direction through the transmission structure, so that the locking rod 12 exits the lock seat 13, thereby releasing the locked state between the door cover 2 and the main body. The locking assembly 1 of this application effectively solves the problem that traditional single-direction locks are prone to incomplete locking. Through the vertical transmission design of the push rod 11 and the locking rod 12, the flexibility of force application is expanded, the risk of unstable locking caused by the limitation of the force application direction is reduced, and the stability of the connection between the door cover 2 and the main body of the anesthesia machine is significantly improved. Meanwhile, the unlocking operation can be achieved simply by pushing the push rod 11 in the first direction, which simplifies the operation process and makes the daily calibration, replacement or maintenance of oxygen cells more convenient and efficient. This further ensures the stability of the oxygen cell installation during the operation of the anesthesia machine and reduces safety hazards such as oxygen cell falling off, gas leakage or contaminant intrusion caused by accidental opening of the door cover 2.

[0035] In addition, such as Figure 1-3 As shown, this application embodiment provides a connection mechanism, including a door cover 2 of an anesthesia machine, a main body of anesthesia machine and the aforementioned locking component 1. The main body is provided with a receiving compartment 31, which is suitable for housing an oxygen cell. The receiving compartment 31 has an opening on one side along a third direction. The door cover 2 is rotatably connected to the main body around a first axis and can open or close the opening. The lock seat 13 is fixedly mounted on the door cover 2. Both the push rod 11 and the locking rod 12 are adapted to be mounted on the main body of the anesthesia machine. The push rod 11 is adapted to be movably connected to the main body along a first direction, and the locking rod 12 is adapted to be movably connected to the main body along a second direction. When the door cover 2 closes the opening, the locking rod 12 can be inserted into the lock seat 13. The extension direction of the first axis is parallel to the first direction, and the first direction, the second direction, and the third direction are perpendicular to each other. In this embodiment, the third direction is the auxiliary direction. Figure 1In the Z direction. Specifically, the locking assembly 1, the door cover 2, and the accommodating compartment 31 are all mounted on the outer shell 3 of the main body. The connection mechanism of this application achieves an efficient balance between oxygen battery maintenance and equipment safety through the spatial adaptation design of the door cover 2, the main body, and the locking assembly 1. The main body accommodating compartment 31 provides a stable placement space for the oxygen battery. The door cover 2 rotates around a first axis parallel to the first direction, and with the three-dimensional perpendicular spatial layout (the first, second, and third directions are mutually perpendicular), the opening and closing trajectory of the door cover 2 is precisely adapted to the operating direction of the locking assembly 1. When closed, the locking rod 12 is precisely inserted into the door cover 2 lock seat 13 under the drive of the elastic element, avoiding the instability of locking caused by directional conflict in traditional structures; when open, pushing the push rod 11 can unlock the door cover 2, and the door cover 2 can rotate without obstruction. This effectively solves the problem of incomplete locking in traditional single-direction locks and significantly improves the stability of the connection between the door cover 2 and the anesthesia machine main body. This ensures the stability of the connection between the cover 2 and the main body, prevents the oxygen battery from falling off due to loosening of the cover 2 or from being contaminated by pollutants, and makes the installation, removal and maintenance of the oxygen battery smoother, significantly improving the safety and convenience of daily use of the anesthesia machine.

[0036] In one embodiment, the connecting mechanism further includes a third elastic element connected between the main body and the door cover 2. The third elastic element has a tendency to drive the door cover 2 to open. In this embodiment, the third elastic element can be a snap ring. By continuously driving the door cover 2 to open, the third elastic element automatically assists the door cover 2 to rotate and open during unlocking, eliminating the need for additional manual force and making it particularly convenient for one-handed maintenance of the oxygen battery. Its elasticity makes the opening process of the door cover 2 smooth and controllable, avoiding the risk of collision or contact caused by sudden pop-out. It complements the locking component 1, ensuring sealing safety when closed and improving the smoothness of opening, making oxygen battery maintenance more efficient and labor-saving.

[0037] According to the connection mechanism provided in this application embodiment, the main body's accommodating compartment 31 is used to place oxygen batteries, and it has an opening on one side along a third direction. The door cover 2 can rotate around a first axis parallel to the first direction, thereby opening or closing the opening. When the door cover 2 closes the opening, the lock seat 13 fixed on the door cover 2 corresponds to the locking rod 12 on the main body. The locking rod 12 moves along a second direction and inserts into the lock seat 13, and the door cover 2 is firmly fixed to the main body by means of the mechanical locking structure of the locking assembly 1. When unlocking, the push rod 11 on the main body is pushed along the first direction. The push rod 11 drives the locking rod 12 to move along the second direction and exit the lock seat 13 through transmission. The door cover 2 can then rotate around the first axis to open the opening, facilitating the operation of the oxygen batteries in the accommodating compartment 31. The connection mechanism of this application breaks the limitation of single-direction unlocking through a three-way vertical spatial layout and a vertical transmission design of push rod 11 - locking rod 12. It significantly reduces the risk of incomplete locking and greatly improves the connection stability between the door cover 2 and the main body; at the same time, the unlocking operation direction is adapted to the opening and closing logic of the door cover 2, avoiding operation jamming, making the opening and closing of the door cover 2 smoother during oxygen battery maintenance, effectively reducing maintenance inconvenience and ensuring the safe operation of the anesthesia machine.

[0038] In addition, such as Figure 2 As shown, this application embodiment provides an anesthesia machine, including an oxygen cell and the above-mentioned connection mechanism, with the oxygen cell disposed in the accommodating chamber 31.

[0039] The anesthesia machine provided according to the embodiments of this application includes the aforementioned connecting mechanism and an oxygen cell disposed in the accommodating chamber 31, effectively solving the chain reaction caused by the traditional locking mechanism. With the help of the three-dimensional vertical spatial layout of the connecting mechanism and the vertical transmission design of the push rod 11 - locking rod 12, the connection stability between the door cover 2 and the main body is greatly improved, avoiding the risk of the oxygen cell loosening or falling out in the accommodating chamber 31 due to inadequate locking, ensuring the accuracy of oxygen concentration monitoring, and improving the safety and reliability of the anesthesia machine operation.
