[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Refer to Figures 1-3 , an embodiment provided by the present invention: a convenient operation and disassembly anesthetic video laryngoscope, including a grip 1, the surface of the grip 1 is provided with anti-slip grooves, so that when medical staff pick it up, it is more stable and will not fall off. The bottom end of the grip 1 is detachably installed with a mirror body 6 through a quick-release mechanism 2. The top end of the grip 1 is provided with an adjustable angle assembly 4. The surface of the mirror body 6 is detachably installed with a protective sleeve 3. The protective sleeve 3 is a prior art. When the mirror body 6 is in use, the protective sleeve 3 can be sleeved outside it to avoid cross-infection. Moreover, the position of the protective sleeve 3 installed on the surface of the mirror body 6 is fixed by friction.

[0041] Refer to Figures 3-5, the quick-release mechanism 2 includes a connecting seat 201. A convex rod 202 is fixedly connected to the left side of the inner wall of the connecting seat 201. A wedge block 207 is elastically connected to the right side of the inner wall of the connecting seat 201 through a return spring 205. One end of the return spring 205 is fixedly connected to the outer wall of the wedge block 207, and the other end of the return spring 205 is fixedly connected to the right side of the inner wall of the connecting seat 201. The function of the return spring 205 is that when the notch of the connecting head 203 is sleeved on the surface of the convex rod 202, its rear end will squeeze the arc surface of the wedge block 207 to make it move backward on the inner side wall of the connecting seat 201 and manually press the button 204 to make the two groups of sliders 210 push the corresponding hinge rods 211 to move synchronously, so that the wedge block 207 can be automatically reset after moving on the inner wall of the connecting seat 201. The connecting seat 201 is fixedly connected to the bottom end of the outer wall of the handle 1. A card slot is opened at the rear end of the connecting seat 201. The outer wall of the wedge block 207 is clamped with the inner wall of the card slot. The clamping between the two can quickly fix the position after the connecting head 203 drives the lens body 6 to be installed on the inner wall of the connecting seat 201. The wedge block 207 is slidably connected to the right inner wall of the connecting seat 201. A cavity is opened at the left side of the bottom end of the connecting seat 201 to facilitate the insertion and installation of the connecting head 203. A guide rod 206 penetrates and is slidably connected to the inner wall of the wedge block 207.

[0042] Refer to Figure 3 and Figure 4, the guide rod 206 is fixedly connected to the inner side wall of the connecting seat 201. The function of the guide rod 206 is to automatically reset the position of the wedge block 207 after movement, and at the same time guide the position when the return spring 205 is compressed to prevent it from bending. One end of the outer wall of the wedge block 207 is hinged with a hinge rod 211, and the end of the hinge rod 211 away from the wedge block 207 is hinged with a slider 210. The outer wall of the slider 210 is slidably connected with a pressing block 204. When the pressing block 204 is pressed, since the wedge block 207 can only move horizontally on the inner wall of the connecting seat 201, at the same time, the pressing of the pressing block 204 will cause the two sliders 210 to move on its surface. At the same time, the hinge rod 211 hinged on the surface of the slider 210 will push the wedge block 207 to move inward on the inner wall of the connecting seat 201, so as to disengage from the card slot of the connector 203, facilitating the removal and replacement of the connector 203. The pressing block 204 penetrates and is slidably connected to the inner wall on the right side of the connecting seat 201. An insertion rod 209 is elastically connected to the inner wall of the pressing block 204 through a limiting spring 208. One end of the limiting spring 208 is fixedly connected to the surface of the insertion rod 209, and the other end of the limiting spring 208 is fixedly connected to the inner wall of the pressing block 204. The function of the limiting spring 208 is to automatically reset the position of the insertion rod 209 after it is pulled upward. The insertion rod 209 penetrates and is slidably connected to the inner wall at the end of the pressing block 204. A slot is opened at the top of the convex block 212, and the bottom end of the outer wall of the insertion rod 209 is inserted into the inner wall of the slot of the convex block 212. The insertion between the two can fix the position where the protective cover 3 is installed on the surface of the lens body 6, and at the same time fix the position of the pressing block 204 to prevent accidental touch of the pressing block 204 during use, resulting in loosening of the connector 203. The surface of the convex rod 202 contacts the connector 203. A notch is opened on the left side of the connector 203, which fits the outer diameter of the convex rod 202. And a cavity is opened on the left side of the connecting seat 201, which fits the outer wall of the connector 203. The connector 203 is fixedly connected to the top end of the outer wall of the lens body 6. A convex block 212 is fixedly connected to the outer wall at the top end of the protective cover 3.

[0043] Refer to Figure 1 and Figure 7, the adjustable angle assembly 4 includes a hinge seat 401, which is hinged to the top end of the outer wall of the grip 1. A torsion screw is provided at the hinge point between the hinge seat 401 and the grip 1, so that the hinge seat 401 can be fixed at multiple positions where it can be hinged and rotated at the top end of the grip 1. A limit block 403 is slidably connected to the inner wall of the top end of the hinge seat 401. The inner wall of the top end of the hinge seat 401 is elastically connected to the limit block 403 through a connecting spring 402. One end of the connecting spring 402 is fixedly connected to the bottom end of the outer wall of the limit block 403, and the other end of the connecting spring 402 is fixedly connected to the inner wall of the top end of the hinge seat 401. The function of the connecting spring 402 is to automatically reset the position of the limit block 403 after the inclined plane at the top end of the limit block 403 is squeezed and moved, and at the same time fix the position of the limit block 403, so that the display 5 will not rotate without being affected by external forces. A limit groove is provided at the bottom end of the display 5. The outer wall of the limit block 403 is in contact with the inner wall of the limit groove. The contact between the two makes the display 5 not rotate without being affected by external forces. The display 5 is rotatably connected to the center of the top end of the hinge seat 401. By providing that the display 5 can rotate circumferentially, the angle of the display 5 can be adjusted when dealing with different angular positions, so as to facilitate the medical staff to observe.

[0044] Working principle: When installing the lens body 6, align the notch of the connector 203 of the lens body 6 with the convex rod 202 and insert it into the cavity on the left side at the bottom end of the connector seat 201. During the insertion of the connector 203, the rear end of it squeezes the arc surface of the wedge block 207, causing the wedge block 207 to move backward on the inner side wall of the connector seat 201 and compress the return spring 205. When the connector 203 is completely inserted, the wedge block 207 is reset under the action of the return spring 205, and its outer wall is clamped with the rear-end card slot of the connector seat 201, quickly fixing the positions of the connector 203 and the lens body 6.

[0045] When the lens body 6 needs to be disassembled, press the button block 204. Pressing the button block 204 causes the two groups of sliders 210 to move on its surface. The sliders 210 push the wedge block 207 to move inward on the inner wall of the connector seat 201 through the hinge rod 211, disengaging from the card slot of the connector 203. At this time, the connector 203 can be taken out of the connector seat 201 to complete the disassembly of the lens body 6. After releasing the button block 204, the limit spring 208 resets the button block 204, and at the same time the return spring 205 resets the wedge block 207 to prepare for the next installation.

[0046] When installing the protective cover 3, put the protective cover 3 on the surface of the mirror body 6 so that the protrusion 212 is aligned with the push block 204. At this time, pull the insertion rod 209 upward, and when it is aligned with the protrusion 212, release the insertion rod 209 and insert it into the slot of the protrusion 212 under the action of the limit spring 208 to fix the position of the protective cover 3 on the surface of the mirror body 6. At the same time, the position of the push block 204 is also fixed to prevent the connector 203 from loosening due to accidental touch. When the protective cover 3 needs to be removed, pull the insertion rod 209 upward to disengage it from the slot of the protrusion 212, and then the protective cover 3 can be removed.

[0047] When the angle of the display 5 needs to be adjusted, external force is applied to rotate the display 5. When the display 5 rotates, the inner wall of its limit groove squeezes the inclined surface of the limit block 403, so that the limit block 403 moves on the inner wall of the top end of the hinge seat 401, compressing the connecting spring 402. When the display 5 is rotated to a suitable angle, the external force is released, and the limit block 403 is reset under the action of the connecting spring 402, contacting the limit groove of the display 5, fixing the angle of the display 5, and facilitating medical staff to observe at different angles.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
