Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0030] Example:

[0031] The embodiment of the utility model provides an anesthesia machine, comprising an anesthesia machine main body and an auxiliary workbench, wherein the auxiliary workbench is assembled on the anesthesia machine main body.

[0032] See also Figures 1 to 4 The auxiliary workbench includes a base 1, a table assembly 2 and a locking structure. The table assembly 2 is rotatably connected to the base 1, and the table assembly 2 can be rotated to an unfolded position and a folded position; the locking structure includes a driving mechanism 3, a lock cylinder 4 and a return member 5, the lock cylinder 4 is slidably assembled on the base 1 and can slide to a first position or a second position; the driving mechanism 3 is assembled on the base 1, and the driving mechanism 3 is used to drive the lock cylinder 4 to slide to the second position; the return member 5 is respectively connected to the lock cylinder 4 and the base 1, and the return member 5 is used to provide a return force to drive the lock cylinder 4 to slide to the first position.

[0033] When the table body assembly 2 is in the unfolded position and the lock core 4 is in the first position, the lock core 4 supports the table body assembly 2, so that the table body assembly 2 is in a locked state, so that the table body assembly 2 remains in the unfolded position; when the table body assembly 2 is in the unfolded position and the lock core 4 is in the second position, the lock core 4 is separated from the table body assembly 2, so that the table body assembly 2 is in an unlocked state, so that the table body assembly 2 can be rotated to the folded position, thereby enabling the table body assembly 2 to achieve self-locking and manual unlocking through the mutual cooperation among the driving mechanism 3, the lock core 4 and the return member 5, effectively preventing users from misunderstanding the lock, and ensuring the safety of operators and items placed on the table body assembly 2 during use.

[0034] It should be noted that, when the platform assembly 2 is in the folded position and the lock core 4 is in the first position, the lock core 4 will press against the platform assembly 2 under the action of the restoring force to keep the platform assembly 2 in the folded position; when the platform assembly 2 is rotated from the folded position to the unfolded position, the platform assembly 2 will press against the lock core 4 to slide the lock core 4 toward the second position; when the platform assembly 2 is in the folded position and the lock core 4 is in the second position, the lock core 4 is separated from the platform assembly 2, and the lock core 4 slides toward the first position under the action of the restoring force.

[0035] See also Figure 2 , Figure 3 and Figure 4 In some embodiments, the lock core 4 includes a slider 41 and a limit shaft 42. The slider 41 is slidably assembled in the base 1, and the slider 41 can slide to the first position or the second position; a receiving cavity 411 is provided at one end of the slider 41, and the limit shaft 42 is fixed to the slider 41 and accommodated in the receiving cavity 411. The driving mechanism 3 is used to drive the slider 41 to slide to the second position through the limit shaft 42. Compared with the driving mechanism 3 directly driving the slider 41, that is, the driving mechanism 3 is connected to the slider 41, the driving mechanism 3 and the lock core 4 can be set separately, thereby reducing the difficulty of assembly.

[0036] It should be understood that in other embodiments, the lock core 4 may only include a slider 41, and the driving mechanism 3 is connected to the slider 41. For example, the driving mechanism 3 may be a lever slidably assembled on the base 1, one end of the lever extends out of the base 1, and the other end is fixedly connected to the slider 41. The slider 41 is driven to move by moving the lever.

[0037] See also Figure 1 , Figure 2 and Figure 3The driving mechanism 3 includes a driving component 31 and a shift block 32. The driving component 31 is movably arranged on the base 1. The shift block 32 is fixedly connected to the driving component 31 and is located in the base 1, so that the shift block 32 can move with the driving component 31; the shift block 32 at least partially extends between the limiting shaft 42 and the inner wall of the accommodating cavity 411, and the limiting shaft 42 is located on the movable track of the shift block 32, so that the shift block 32 can push against the limiting shaft 42 to move, thereby driving the slider 41 to slide.

[0038] It should be noted that when the slider 41 is in the first position, there is a gap between the shift block 32 and the limiting shaft 42 and between the shift block 32 and the inner wall of the accommodating chamber 411, so as to ensure that the slider 41 does not contact the shift block 32 when the platform assembly 2 pushes against the lock cylinder 4 and slides toward the second position, thereby preventing the slider 41 from driving the shift block 32 to move. In addition, since the shift block 32 extends between the limiting shaft 42 and the inner wall of the accommodating chamber 411, the shift block 32 can limit the slider 41 to prevent the slider 41 from sliding inside the base 1.

[0039] See also Figure 2 and Figure 3 The driving assembly 31 includes a handle 311 and a first connecting shaft 312. The first connecting shaft 312 is rotatably arranged in the base 1. The handle 311 and the shift block 32 are respectively fixedly connected to the two ends of the first connecting shaft 312, so that the first connecting shaft 312 can be driven to rotate by driving the handle 311, and the shift block 32 rotates following the first connecting shaft 312. The limit shaft 42 is located on the rotation track of the shift block 32, so that the shift block 32 can rotate until it hits the limit shaft 42. The handle 311 is located on the outside of the base 1, which is convenient for applying force to the handle 311 to drive the first connecting shaft 312 to rotate; the first connecting shaft 312 and the limit shaft 42 are parallel to each other, so that the slider 41 slides in a direction perpendicular to the first connecting shaft 312, which is conducive to improving the smoothness and stability of the sliding of the slider 41.

[0040] According to actual needs, such as Figure 3 As shown, the shift block 32 includes a fixing portion 321 sleeved and fixed on the outside of the first connecting shaft 312 , and an abutting portion 322 fixed to an end of the fixing portion 321 away from the first connecting shaft 312 , and the abutting portion 322 extends between the limiting shaft 42 and the inner wall of the accommodating cavity 411 .

[0041] See also Figure 1 , Figure 2 and Figure 4The platform assembly 2 includes a support platform 21, a connecting arm 22 and an abutting shaft 23. One end of the connecting arm 22 is rotatably connected to the base 1, and the other end is connected to the support platform 21. The support platform 21 is rotatably arranged on the base 1 through the connecting arm 22. The abutting shaft 23 is fixed to the connecting arm 22; wherein, when the support platform 21 is in the unfolded position and the lock cylinder 4 is in the first position, the lock cylinder 4 supports the abutting shaft 23, so that the support platform 21 is kept in the unfolded position to achieve self-locking; when the support platform 21 is in the unfolded position and the lock cylinder 4 is in the second position, the lock cylinder 4 is separated from the abutting shaft 23, so that the support platform 21 can be rotated to the folded position to achieve unlocking.

[0042] See also Figure 1 , Figure 2 and Figure 3 The connecting arm 22 includes a first arm 221 and a second arm 222 which are spaced apart and rotatably connected to the base 1. Both ends of the abutment shaft 23 are respectively fixed to the first arm 221 and the second arm 222, so that sufficient space is left around the abutment shaft 23 to ensure that the slider 41 is in contact with the abutment shaft 23. At the same time, the abutment shaft 23 can ensure that the first arm 221 and the second arm 222 rotate synchronously, which is beneficial to improving the smoothness of the rotation of the support platform 21.

[0043] See also Figure 2 and Figure 4 A support surface 412 is provided on the side of the lock core 4 close to the support platform 21, and a guide slope 413 is provided on the side of the lock core 4 away from the return member 5, and the guide slope 413 is arranged adjacent to the support surface 412. Specifically, during the process of the support platform 21 rotating from the folded position to the unfolded position, the abutment shaft 23 will abut against the guide slope 413, and the slider 41 will slide toward the second position under the abutment of the abutment shaft 23 until the support platform 21 rotates to the unfolded position. At this time, the slider 41 slides toward the first position under the action of the restoring force, and the support platform 21 abuts against the support surface 412, so that the support platform 21 is locked in the unfolded position.

[0044] See also Figure 2 and Figure 4The platform assembly 2 further includes a second connecting shaft 24, which is fixed to the base 1, and the connecting arm 22 is rotatably connected to the second connecting shaft 24, so that the connecting arm 22 is rotatably set on the base 1 through the second connecting shaft 24. Specifically, the second connecting shaft 24 can be fixed to the base 1 by screws, and the first arm 221 and the second arm 222 are rotatably connected to the two second connecting shafts 24 one by one, respectively, and a gasket 6 is provided between the first arm 221, the second connecting shaft 24 and the base 1, and between the second arm 222, the second connecting shaft 24 and the base 1. The provision of the gasket 6 can make the assembly between the first arm 221, the second connecting shaft 24 and the base 1, and between the second arm 222, the second connecting shaft 24 and the base 1 loose, so as to make the rotation of the first arm 221 and the second arm 222 on the corresponding second connecting shaft 24 smoother.

[0045] See also Figure 3 and Figure 4 , a positioning portion 43 is provided at one end of the lock core 4, a return member 5 is sleeved on the outside of the positioning portion 43, and the return member 5 abuts against the lock core 4 and the base 1 respectively. Specifically, the return member 5 can be a spring, the positioning portion 43 can be a column, the spring is sleeved on the outside of the column, and the two ends of the spring abut against the slider 41 and the base 1 respectively, so that the spring is fixed between the slider 41 and the base 1, ensuring that the spring can provide a restoring force to drive the slider 41 to slide to the first position. According to actual needs, two positioning portions 43 can be provided, and two return members 5 are provided, and the two return members 5 are sleeved on the two positioning portions 43 respectively, so that a sufficiently large restoring force can be provided to drive the slider 41 to slide to the first position.

[0046] See also Figure 2 In some embodiments, the base 1 is fixed on the anesthesia machine body, and an arc portion is provided on the outer side of the base 1, and the arc portion is connected to the anesthesia machine body; a groove is provided inside the base 1, and the slider 41 and the shift block 32 are both provided in the groove.
