The top surface of the sliding plate 20 is provided with a slide-in channel 211 and a slide-out channel 212, and it is understood that the slide-in channel 211 and the slide-out channel 212 are accommodated in the limiting chamber 101. The start point of the slide-in channel 211 communicates with the end point of the slide-out channel 212, and a common channel is formed between the start point of the slide-in channel 211 and the end point of the slide-out channel 212. The end point of the slide-in channel 211 is connected to the start point of the slide-out channel 212 and forms a groove 213. The slide-in groove 211 and the slide-out groove 212 are both arc-shaped, and the bending directions of the slide-in groove 211 and the slide-out groove 212 are directed toward the slide cam 22. That is, the slide-in channel 211 and the slide-out channel 212 form a Y-like shape.
In addition, a portion of the bottom plate 10 contacting the slide protrusion 22, which portion is formed with the inclined portion 13 toward the end of the second stopper plate 122. The inclined portion 13 gradually decreases in thickness from the first stopper plate 121 to the second stopper plate 122. An elastic hook 215 is connected to an end of the sliding protrusion 22, and the elastic hook 215 is also disposed toward the second limiting plate 122. The elastic hook 215 performs a retracting or ejecting motion along the inclined portion 13. Specifically, the elastic hook 215 includes a connecting rod 2151 and a buckle 2152, the connecting rod 2151 is made of an elastic material, and the buckle 2152 is made of a hard material.
One end of the elastic member 30 is fixedly connected to the position-limiting plate 12, and the other end is connected to the end of the sliding plate 20. It is understood that the elastic member 30 may be directly fixedly coupled to the base plate 10. The elastic member 30 may be, but is not limited to, a spring.
One end of the stopper rod 40 is fixedly coupled to the base plate 10, and the other end thereof moves in the slide-in groove 211 or the slide-out groove 212. It is understood that the stop lever 40 may also be fixedly connected to the stop plate 12.

In the working state of fig. 3, the fixed ends of the elastic member 30 and the stopper rod 40 are on the opposite side of the stopper plate 12, that is, the fixed end of the elastic member 30 is connected to the second stopper plate 122, and the fixed end of the stopper rod 40 is located on the side of the first stopper plate 121. The sliding plate 20 moves toward the fixed end of the limiting rod 40 under the pushing of an external force, the elastic member 30 is stretched, and the limiting rod 40 enters the groove 213 along the slide-in channel 211 to be fixed. If the fixed ends of the elastic element 30 and the limiting rod 40 are on the same side of the limiting plate, that is, the fixed ends of the elastic element 30 and the limiting rod 40 are both close to one side of the first limiting plate 121. At this time, the elastic member 30 is compressed, and the stopper 40 is fixed along the slide-in groove 211 into the groove 213.

Referring to fig. 5 and fig. 6, the present invention further provides a device using the above-mentioned ejection mechanism 100, which includes a member to be fixed 200 and the ejection mechanism 100.
Specifically, the member to be fixed 200 is fixed by being engaged with the slide plate 20 by the catch 2152. The slide protrusion plate 22 of the slide plate 20 protrudes toward the member to be fixed 200 with a fixing block 221, and the bottom surface of the member to be fixed 200 is opened with a fixing groove (not shown), and the fixing block 221 is engaged with the fixing groove (not shown) to primarily fix the member to be fixed 200 and the slide plate 20.
The bottom surface of the member to be fixed 200 is provided with a slot 201 matched with the elastic hook 215. The slot 201 is specifically matched with the buckle 2152 of the elastic hook 215 to fix the to-be-fixed member 200 and the sliding plate 20.
When the fixing member 200 needs to be fixed, referring to fig. 3 and fig. 6, the fixing member 200 is pushed by external force and moves toward the first position-limiting plate 121, so as to drive the sliding plate 20 to move toward the fixed end of the position-limiting rod 40, the elastic member 30 is stretched, the position-limiting rod 40 slides into the groove 211 along the slide-in groove 211, and the fixing member 200 is fixed. Meanwhile, as the elastic hook 215 moves along with the sliding plate 20, the elastic hook 215 is pushed up by the inclined portion 13, and the buckle 2152 of the elastic hook 215 is engaged with the groove 201 on the bottom surface of the to-be-fixed member 200, so as to complete the final fixation of the to-be-fixed member 200.
When the member to be fixed 200 needs to be detached, referring to fig. 4 and fig. 6, the member to be fixed 200 is pushed by an external force, the sliding plate 20 is driven to move towards the fixed end of the limiting rod 40, the limiting rod 40 enters the sliding-out channel 212 from the groove 213, and the elastic element 30 retracts to drive the sliding plate 20 to return to the initial state. Meanwhile, as the elastic hook 215 moves along with the sliding plate 20, the buckle 2152 of the elastic hook 215 slowly moves away from the slot 201 on the bottom surface of the to-be-fixed member 200. And finishing the disassembly after the fixing piece 200 is popped out.
The pop-up mechanism 100, the to-be-fixed member 200 and the pop-up mechanism 100 are fixed without screws. The automatic ejection of the to-be-fixed piece 200 is realized by the matching of the limiting rod 40, the slide-in channel 211 and the slide-out channel 212. The whole device is simple in structure, small in size, stable in installation and high in practicability.
In practical use, the fixing member 200 may be a blood oxygen module. By using the pop-up mechanism 100 provided by the present invention to fix the blood oxygen module, the pop-up mechanism 100 can realize the functions of pushing the fixed blood oxygen module inwards and then pushing and ejecting the blood oxygen module. The blood oxygen module can be used with the whole machine as a whole, and can also be taken out of the whole machine as an independent part for use.
After the pop-up mechanism 100 is used, the relative position of the blood oxygen module in the whole machine is fixed, so that an independent charging seat is not needed to be designed, the external power supply of the blood oxygen module is manually charged, and the charging pin is arranged in the whole machine, so that the effect that the blood oxygen module immediately starts to be automatically charged when being placed in the whole machine is realized.
It is understood that the ejection mechanism 100 is not limited to fixing the blood oxygen module, and the member to be fixed 200 may be selectively adapted to fit the components or devices similar to the blood oxygen module.
In addition, other modifications within the spirit of the invention may occur to those skilled in the art, and such modifications are, of course, included within the scope of the invention as claimed.
