Detailed implementation manners

[0034] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The term "integrally formed" means that during the process of forming one of the multiple components, this component is connected to other components together without the need to connect the two components through a reprocessing method (such as bonding, welding, snap connection, screw connection). The terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as implying or indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include one or more of such features. The orientation terms mentioned in the embodiments of the present application, such as "top", "bottom", "side", "inside", "outside", etc., are only with reference to the direction of the drawings. Therefore, the orientation terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus cannot be understood as a limitation to the embodiments of the present application.

[0035] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0036] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of an anesthesia machine 1000 provided by an embodiment of the present application. Figure 2 It is Figure 1 a schematic structural diagram of a partial structure of the anesthesia machine 1000 shown in one state. Figure 3 It is Figure 1 a schematic structural diagram of a partial structure of the anesthesia machine 1000 shown in another state. Exemplarily, Figure 2 it shows a schematic assembly structure of the workbench 200 and the connecting mechanism 300 when the workbench 200 of the anesthesia machine 1000 is in an open state. Figure 3 it shows a schematic assembly structure of the workbench 200 and the connecting mechanism 300 when the workbench 200 of the anesthesia machine 1000 is in a retracted state.

[0037] In some embodiments, the anesthesia machine 1000 may include a body 100, a workbench 200, and a connecting mechanism 300. Among them, the connecting mechanism 300 is connected between the body 100 and the workbench 200. The workbench 200 can be in a first position or a second position relative to the body 100 through the movement of the connecting mechanism 300. That is to say, the workbench 200 can switch between the first position and the second position relative to the body 100. It can be understood that when the workbench 200 is in the first position, the workbench 200 can be in an open state relative to the body 100. At this time, the workbench 200 can expand the workbench surface of the body 100 for placing some medicaments and tools, etc. When the workbench 200 is in the second position, the workbench 200 is in a retracted state relative to the body 100. At this time, the workbench 200 can be folded on one side of the body 100, which is beneficial to avoiding collision between the workbench 200 and other components outside the anesthesia machine 1000.

[0038] Exemplarily, the number of the connecting mechanisms 300 can be two, and the two connecting mechanisms 300 are respectively connected between the body 100 and the workbench 200. The two connecting mechanisms 300 can be fixedly connected through a bracket 301, so that the two connecting mechanisms 300 can move synchronously. The two connecting mechanisms 300 can improve the stability of the workbench 200 when rotating relative to the body 100.

[0039] In the present application, the structures of the two connecting mechanisms 300 can be the same or there can be a slight difference. The structure of one of the connecting mechanisms 300 will be introduced below. The structure of the other connecting mechanism 300 can be the same as that of the first connecting mechanism 300, or the structure of the other connecting mechanism 300 can also not include a part of the structure of the first connecting mechanism 300.

[0040] Please refer to Figure 4 and Figure 5 , Figure 4 which is Figure 2 a partial schematic structural view of the connecting mechanism 300 shown in Figure 5 and Figure 3 is also a partial schematic structural view of the connecting mechanism 300 shown in . Exemplarily, Figure 4 shows a partial schematic structural view of the connecting mechanism 300 when the workbench 200 is in an open state relative to the machine body 100. Figure 5 shows a partial schematic structural view of the connecting mechanism 300 when the workbench 200 is in a retracted state relative to the machine body 100.

[0041] In some embodiments, the connecting mechanism 300 may include a fixing member 31, a rotating member 32, and a rotating shaft 33. Among them, the fixing member 31 is used to connect the machine body 100 of the anesthesia machine 1000. One end of the rotating member 32 is connected to the workbench 200, and the other end is connected to the fixing member 31. Among them, the rotating shaft 33 may be located between the rotating member 32 and the fixing member 31. The rotating member 32 can rotate relative to the fixing member 31 around the rotating shaft 33 to drive the workbench 200 to rotate relative to the machine body 100, so that the workbench 200 can be switched between an open state and a retracted state.

[0042] Exemplarily, the fixing member 31 may have a fastening hole 310. The anesthesia machine 1000 can pass a fastener (such as a screw, a bolt, etc.) through the fastening hole 310 of the fixing member 31, so that the fastener can fix the fixing member 31 on the machine body 100. One end of the rotating member 32 can also be fixed to one side of the back working surface of the workbench 200 through a fastener (such as a screw, a bolt, etc.). It can be understood that the working surface of the workbench 200 is the surface for placing articles, medicines, etc. when the workbench 200 is in an open state relative to the machine body 100.

[0043] Please refer to Figure 6 , Figure 6 which is Figure 2 a partial exploded view of the connecting mechanism 300 shown in .

[0044] In some embodiments, the rotating member 32 may include a top wall 321 and a bottom wall 322 arranged opposite to each other, and a side wall 323 connecting the top wall 321 and the top wall 321. Exemplarily, the rotating member 32 may have a limiting hole 324 and a rotating hole 325 arranged at intervals. The limiting hole 324 can penetrate through the top wall 321 and the bottom wall 322 of the rotating member 32. The rotating hole 325 can penetrate through the top wall 321 and the bottom wall 322 of the rotating member 32. Among them, the rotating hole 325 can be used for the rotating shaft 33 to pass through.

[0045] Exemplarily, the rotating member 32 may further have a first limiting portion 326 and a rotating portion 327. The first limiting portion 326 is fixedly connected to the rotating portion 327 and protrudes from the rotating portion 327. Figure 6 In Figure 6 , the first limiting portion 326 and the rotating portion 327 of the rotating member 32 are schematically distinguished by dashed lines. Exemplarily, both the limiting hole 324 and the rotating hole 325 of the rotating member 32 may be located in the rotating portion 327. The first limiting portion 326 may be located on the side of the rotating hole 325 away from the limiting hole 324.

[0046] Exemplarily, the first limiting portion 326 and the rotating portion 327 may be an integrally formed structural member. In other embodiments, the first limiting portion 326 may also be connected to one side of the rotating portion 327 by other processes (such as welding, bonding, or clamping, etc.). The present application does not limit this.

[0047] In some embodiments, the connecting mechanism 300 may further include a locking member 34, a fixed seat 35, and an elastic member 36. Among them, the locking member 34 may have a main body portion 341 and a protruding portion 342. The protruding portion 342 is connected to the main body portion 341 and protrudes from the main body portion 341. Exemplarily, the main body portion 341 may be generally strip-shaped. The protruding portion 342 may be generally annular. The protruding portion 342 is disposed around the circumferential side of the main body portion 341.

[0048] Exemplarily, the main body portion 341 and the protruding portion 342 may be an integrally formed structural member. In other embodiments, the protruding portion 342 may be connected to the circumferential side of the main body portion 341 by other processes (such as welding, bonding, or clamping, etc.). The present application does not limit this.

[0049] Exemplarily, the fixed seat 35 may have a through hole 351. An abutting portion 3511 is provided on the hole wall of the through hole 351. The abutting portion 3511 may be formed by protruding from the hole wall of the through hole 351 towards the center of the through hole 351. The abutting portion 3511 may be generally annular.

[0050] In some embodiments, the connecting mechanism 300 may further include a shaft sleeve 37. Exemplarily, the shaft sleeve 37 may include a first connecting portion 371 and a second connecting portion 372. The second connecting portion 372 is fixedly connected to the first connecting portion 371 and is located on one side of the first connecting portion 371.

[0051] Exemplarily, the first connecting portion 371 and the second connecting portion 372 may be an integrally formed structural member. In other embodiments, the second connecting portion 372 may also be connected to one side of the first connecting portion 371 by other processes (such as welding, bonding, or clamping, etc.). The present application does not limit this.

[0052] Please refer to Figures 6 to 7B , Figure 7A For Figure 6Schematic structural diagrams of the fixing member 31 shown at different angles Figure 7B is Figure 6 Schematic structural diagram of the fixing member 31 shown at another angle

[0053] In some embodiments, the fixing member 31 may include a first part 311 and a second part 312 that are opposite and spaced apart, and a third part 313 connecting the first part 311 and the second part 312. Among them, the third part 313 may be used to connect the body 100 of the anesthesia machine 1000

[0054] Exemplarily, the fixing member 31 may have a mounting groove 314. The mounting groove 314 may be located in the first part 311, and the opening of the mounting groove 314 may be exposed on the surface of the first part 311 facing away from the second part 312. In some other examples, the mounting groove 314 may be located in the second part 312, and the opening of the mounting groove 314 may be exposed on the surface of the second part 312 facing away from the first part 311

[0055] Exemplarily, the fixing member 31 may also have a spaced-apart jack 315 and a connection hole 316. The jack 315 may penetrate through the first part 311 and the second part 312. The connection hole 316 may penetrate through the first part 311 and the second part 312. In other words, the first part 311 may have the jack 315 and the connection hole 316, and the second part 312 may also have the jack 315 and the connection hole 316. Among them, the jack 315 of the fixing member 31 may penetrate through the bottom wall of the mounting groove 314

[0056] Exemplarily, the fixing member 31 may also have a second limiting portion 317. The second limiting portion 317 may be fixedly connected to the first part 311 and / or the second part 312 of the fixing member 31, and at least part of it is located between the first part 311 and the second part 312. In some examples, the connecting mechanism 300 may pass a fastener (such as a screw, a bolt, etc.) through the first part 311 and / or the second part 312 of the fixing member 31, so that a part of the fastener may form the second limiting portion 317 of the fixing member 31

[0057] Please refer to Figure 6 and Figure 8 , Figure 8 is Figure 4 Partial cross-sectional schematic diagram of a partial structure of the connecting mechanism 300 shown in the figure cut along the A-A

[0058] In some embodiments, the rotating member 32 is rotatably located between the first part 311 and the second part 312 of the fixing member 31. The rotating shaft 33 can pass through the fixing member 31 and the rotating member 32. Exemplarily, the rotating shaft 33 can penetrate through the first part 311 and the second part 312 of the fixing member 31. The rotating shaft 33 can pass through the connecting hole 316 of the fixing member 31 and the rotating hole 325 of the rotating member 32.

[0059] Exemplarily, the sleeve 37 can be sleeved outside the rotating shaft 33. Among them, the first connecting part 371 of the sleeve 37 can be located between the rotating member 32 and the fixing member 31. The second connecting part 372 of the sleeve 37 can be located in the connecting hole 316 of the fixing member 31, that is, the second connecting part 372 can be located between the rotating shaft 33 and the fixing member 31.

[0060] In the embodiments of the present application, by providing the sleeve 37, on the one hand, the first connecting part 371 of the sleeve 37 can be located between the rotating member 32 and the fixing member 31, so that the first connecting part 371 of the sleeve 37 can limit the movement of the rotating member 32 relative to the fixing member 31 in the direction parallel to the axial direction of the rotating shaft 33, making it difficult for the rotating member 32 to shake relative to the fixing member 31, and the connection stability between the rotating member 32 and the fixing member 31 is better; on the other hand, the second part 312 of the sleeve 37 can be located between the rotating shaft 33 and the fixing member 31, which can prevent the rotating shaft 33 from directly contacting and rubbing against the fixing member 31, thereby reducing the risk of wear of the rotating shaft 33 and being beneficial to extending the service life of the rotating shaft 33.

[0061] Exemplarily, the number of sleeves 37 can be two. The two sleeves 37 are respectively sleeved at both ends of the rotating shaft 33 and are located on the opposite sides of the rotating member 32.

[0062] In some embodiments, the connecting mechanism 300 can further include two snap rings 331. The two snap rings 331 are respectively sleeved at both ends of the rotating shaft 33 extending out of the fixing member 31. The two snap rings 331 are respectively abutted against the first part 311 and the second part 312 of the fixing member 31, thereby restricting the axial movement of the rotating shaft 33.

[0063] In some embodiments, the fixed seat 35 can be fixedly connected to the side of the fixing member 31 facing away from the rotating member 32. Exemplarily, a part of the fixed seat 35 can be embedded in the installation groove 314 of the fixing member 31. In the embodiments of the present application, by providing the installation groove 314 in the fixed seat 35 and embedding a part of the fixed seat 35 into the installation groove 314, the groove wall of the installation groove 314 can restrict the relative displacement between the fixed seat 35 and the fixing member 31 in a plane perpendicular to the axial direction of the rotating shaft 33, thereby being beneficial to improving the connection stability between the fixed seat 35 and the fixing member 31.

[0064] Exemplarily, the through hole 351 of the fixed seat 35 is opposite to and communicated with the jack 315 of the fixing member 31. The main body portion 341 of the locking member 34 is movably inserted through the through hole 351 of the fixed seat 35 and the jack 315 of the fixing member 31. Figure 8 The main body portion 341 and the protruding portion 342 of the locking member 34 are schematically divided by a dashed line in Figure 8 .

[0065] Exemplarily, the elastic member 36 can be sleeved on the main body portion 341 of the locking member 34. The elastic member 36 elastically abuts against the protruding portion 342 of the locking member 34 and the abutting portion 3511 of the fixed seat 35 respectively. Figure 8 The abutting portion 3511 of the fixed seat 35 is schematically divided by a dashed line in Figure 8 . Exemplarily, the elastic member 36 can be a spring, a compression spring, etc. The elastic member 36 is in a compressed state. The elastic member 36 has an elastic force on the locking member 34. Under the action of the elastic force of the locking member 34, the protruding portion 342 of the locking member 34 has a tendency to move closer to the rotating member 32.

[0066] As Figure 8 shown, the rotating member 32 rotates until the limiting hole 324 is opposite to the jack 315 of the fixing member 31. The locking member 34 extends out of the jack 315 and is inserted through the limiting hole 324 of the rotating member 32. Exemplarily, the locking member 34 can penetrate through the first part 311 and the second part 312 of the fixing member 31. The protruding portion 342 of the locking member 34 abuts against the fixing member 31. Exemplarily, the protruding portion 342 of the fixing member 31 can abut against the bottom wall of the mounting groove 314 under the action of the elastic force of the locking member 34. At this time, the rotating member 32 no longer rotates relative to the fixing member 31, that is, the rotating member 32 is locked by the locking member 34.

[0067] In the embodiment of the present application, the locking member 34 can extend out of the jack 315 of the first part 311 and be inserted into the jack 315 of the second part 312. It can be understood that a part of the locking member 34 can be located in the jack 315 of the first part 311, and a part can be located in the jack 315 of the second part 312, so that the locking member 34 is not easy to shake relative to the fixing member 31. In this way, the locking member 34 has a good locking effect on the rotating member 32, and the rotating member 32 is not easy to rotate relative to the fixing member 31 after being locked by the locking member 34.

[0068] Please refer to again Figure 6 and Figure 8, in some embodiments, the connecting mechanism 300 may further include a handle 38. The handle 38 may be fixedly connected to one end of the locking member 34 away from the fixing member 31. Exemplarily, one end of the locking member 34 away from the fixing member 31 may be inserted into the handle 38. The connecting mechanism 300 may further be provided with fasteners (such as screws, bolts, etc.) passing through the handle 38 and the locking member 34, so as to fix the locking member 34 to the handle 38. In the embodiments of the present application, the user may pull the handle 38 in a direction away from the fixing member 31, so that the handle 38 drives the locking member 34 to move relative to the fixing seat 35 and the fixing member. At this time, the protruding portion 342 of the locking member 34 may further compress the elastic member 36. The locking member 34 may extend out of the limiting hole 324 of the rotating member 32.

[0069] Please refer to Figure 9 and Figure 10 , Figure 9 is Figure 4 a partial cross-sectional view of a part of the connecting mechanism 300 shown in FIG. Figure 10 is Figure 4 a partial cross-sectional view of a part of the connecting mechanism 300 shown in FIG.

[0070] In some embodiments, when the locking member 34 passes through the limiting hole 324, the second limiting portion 317 of the fixing member 31 may abut against the first limiting portion 326 of the rotating member 32. In the embodiments of the present application, by providing the first limiting portion 326 on the rotating member 32 and the second limiting portion 317 on the fixing member 31, the first limiting portion 326 and the second limiting portion 317 can limit the rotation angle of the rotating member 32 relative to the fixing member 31, avoiding the rotating member 32 rotating too large an angle relative to the fixing member 31; and when the first limiting portion 326 abuts against the second limiting portion 317, the limiting hole 324 of the rotating member 32 is opposite to the insertion hole 315 of the fixing member 31, facilitating the locking member 34 to pass through the insertion hole 315 and the limiting hole 324 at the same time. That is, the first limiting portion 326 and the second limiting portion 317 also have a positioning function.

[0071] Please refer to Figure 5 and Figure 11 , Figure 11 is Figure 5 a partial cross-sectional view of a part of the connecting mechanism 300 shown in FIG.

[0072] In some embodiments, when the rotating member 32 rotates to a position where the rotating member 32 is offset from the insertion hole 315, the locking member 34 can extend from the insertion hole 315 and be located on one side of the rotating member 32. Exemplarily, the locking member 34 can be located on one side of the rotating member 32 close to the side wall 323. At this time, the locking member 34 can limit the rotation angle of the rotating member 32 relative to the fixed member 31 about the rotating shaft 33. That is, when the rotating member 32 rotates relative to the fixed member 31 until the side wall 323 abuts against the locking member 34, the locking member 34 can prevent the rotating member 32 from continuing to rotate relative to the fixed member 31.

[0073] In some embodiments, the locking member 34 can abut against the side wall 323 of the rotating member 32. At this time, the locking member 34 can limit the rotation of the rotating member 32 relative to the fixed member 31, so that the rotating member 32 is not likely to shake relative to the fixed member 31.

[0074] In some embodiments, the rotating member 32 can further have an avoidance surface 328. The avoidance surface 328 can connect the top wall 321 and the bottom wall 322 of the rotating member 32. The avoidance surface 328 can be disposed adjacent to the side wall 323. Exemplarily, at least a section of the avoidance surface 328 is an arc surface. The first limiting portion 326 is connected to the avoidance surface 328 and protrudes from the avoidance surface 328. During the rotation of the rotating member 32 relative to the fixed member 31, the avoidance surface 328 can be used to avoid the second limiting portion 317 of the fixed member 31, preventing the rotating member 32 from colliding with the second limiting portion 317.

[0075] Please refer to Figure 2 and Figure 6 , in some embodiments, the connecting mechanism 300 can further include a housing 39. The housing 39 can be located outside the fixed member 31 and the fixed seat 35. On the one hand, the housing 39 can be used to protect the fixed member 31 and the fixed seat 35, thereby reducing the risk of damage to the fixed member 31 and the fixed seat 35 caused by collision with external components, and thus facilitating the improvement of the reliability of the fixed member 31, the fixed seat 35, and the connecting mechanism 300. On the other hand, the housing 39 can surround the outside of the fixed member 31 and the fixed seat 35, so that the appearance aesthetics and consistency of the connecting mechanism 300 are better.

[0076] It can be understood that the above mainly introduces the structure of the connecting mechanism 300 of the anesthesia machine 1000 in two different states (the open state and the storage state). The following will continue to introduce the process of switching between the two states of the connecting mechanism 300 of the anesthesia machine 1000 in combination with the relevant drawings.

[0077] Please refer to Figure 8 , Figure 12 and Figure 13 , Figure 12 For Figure 2The schematic diagram of a partial cross section of a part of the mechanism of the anesthesia machine 1000 is shown along EE. Figure 13 for Figure 3 The diagram is a partial cross-sectional diagram of a portion of the mechanism of the anesthesia machine 1000 cut along FF.

[0078] In the embodiment of the present application, the rotating member 32 can rotate relative to the fixed member 31 around the rotating shaft 33, so that the limiting hole 324 of the rotating member 32 is opposite to the insertion hole 315 of the fixed member 31. At this time, the locking member 34 can extend from the insertion hole 315 of the fixed member 31 and pass through the limiting hole 324 of the rotating member 32 to lock the rotating member 32, so that the workbench 200 can be relative to the machine body 100 (see Figure 1 ) is in an open state and is not prone to shaking relative to the body 100.

[0079] When the workbench 200 needs to be stored, the user can pull the handle 38 in a direction away from the fixing member 31, so that the locking member 34 compresses the elastic member 36 and extends from the limiting hole 324 of the rotating member 32, so that the rotating member 32 can continue to rotate relative to the fixing member 31 around the rotating shaft 33. When the rotating member 32 rotates until the insertion hole 315 of the rotating member 32 and the fixing member 31 are offset, the protrusion 342 of the locking member 34 can extend from the insertion hole 315 of the fixing member 31 under the elastic force of the elastic member 36 and be located on one side of the rotating member 32. At this time, the workbench 200 can be relatively moved relative to the machine body 100 (see Figure 1 ) is in storage state.

[0080] In the embodiment of the present application, after the user pulls the handle 38 to rotate the rotating member 32 until the top wall 321 is opposite to the locking member 34, the handle 38 can be released. At this time, the locking member 34 can abut against the top wall 321 of the rotating member 32 under the elastic force of the elastic member 36. The rotating member 32 can still continue to rotate relative to the fixed member 31 until the rotating member 32 rotates until the top wall 321 is offset from the locking member 34, and the locking member 34 can be located on one side of the rotating member 32 under the elastic force of the elastic member 36. That is, the locking member 34 can be automatically reset under the elastic force of the elastic member 36.

[0081] Of course, in some other embodiments, the connection mechanism 300 may not include the elastic member 36 . When the rotating member 32 rotates to be offset from the insertion hole 315 , the user can manually push the handle 38 to make the locking member 34 located on one side of the rotating member 32 .

[0082] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.

[0083] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. That is to say, the above-described multiple embodiments can also be arbitrarily combined according to actual needs. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
