Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "installed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via other components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] Based on the problems pointed out in the background technology that the existing lid opening mechanism is large in size and high in cost, and the use of a motor to drive the lid opening cannot make the barrel lid thicker, thereby affecting the thermal insulation performance. The lid opening mechanism of the present invention is provided with a slide groove on the fixing device and a first sliding member on the second connecting component, and the first sliding member is provided in the slide groove, so that the first connecting component can be rotated under the drive of the driving mechanism to drive the second connecting component to move, and then the first sliding member slides along the groove wall of the slide groove in the slide groove, thereby opening or closing the barrel lid; this structural setting uses a driving mechanism to realize the opening and closing of the barrel lid, which has a simple structure, small size, low cost, and is easy to assemble and use. In addition, the driving mechanism can drive the barrel lid to move vertically and flip, and the vertical movement can completely separate or close the barrel lid and the barrel, which can be suitable for barrel lids with larger thicknesses and can open the lid quickly.

[0047] Specifically, if Figure 1 and Figure 2 As shown, the cover opening mechanism of the present invention includes a fixing device 1 and a driving mechanism 2, a first connecting component 3 and a second connecting component 4 installed on the fixing device 1.

[0048] Among them, the second connecting component 4 is fixedly connected to the barrel cover 5; the first end of the first connecting component 3 is drive-connected to the driving mechanism 2, and can be rotated with the first end of the first connecting component 3 as the rotating shaft under the drive of the driving mechanism 2, and the second end of the first connecting component 3 is pivotally connected to the second connecting component 4; a slide groove 6 is provided on the fixing device 1, and a first sliding member 7 adapted to the slide groove 6 is provided on the second connecting component 4. The first sliding member 7 is located in the slide groove 6 and can slide along the length direction of the slide groove 6; the first connecting component 3 can drive the first sliding member 7 to slide along the slide groove 6 during the rotation process, and thus the second connecting component 4 drives the barrel cover 5 to move vertically and flip in sequence during the opening process.

[0049] The lid opening mechanism of the present invention is provided with a fixing device 1, a driving mechanism 2, a first connecting component 3 and a second connecting component 4, and a chute 6 is provided on the fixing device 1, and a first sliding member 7 is provided on the second connecting component 4. The first sliding member 7 is located in the chute 6 and can slide along the length direction of the chute 6. The driving mechanism 2 can drive the first connecting component 3 to rotate, thereby driving the second connecting component 4 to move. When the second connecting component 4 moves, it drives the first sliding member 7 to slide along the chute 6. The chute 6 limits the sliding direction of the first sliding member 7, and then during the lid opening process, the second connecting component 4 drives the barrel cover 5 to move vertically and flip in sequence. When the barrel cover 5 moves vertically, it can completely separate from the barrel. After that, the barrel cover 5 flips and fully opens the top opening of the barrel to facilitate the removal of cryopreservation tubes. When closing the lid, under the drive of the driving mechanism 2, the second connecting component 4 drives the barrel cover 5 to flip and move vertically in sequence.

[0050] It should be noted that the present invention does not impose any limitation on the specific structure of the fixing device 1 , and those skilled in the art can set the structure of the fixing device 1 according to actual needs.

[0051] Preferably, if Figure 2 and Figure 3 As shown, the fixing device 1 includes a first fixing member 11 and a second fixing member 12. The first fixing member 11 is arranged horizontally, the second fixing member 12 is vertically installed on the first fixing member 11, the slide groove 6 is arranged on the second fixing member 12, and the driving mechanism 2 is installed on the first fixing member 11.

[0052] The fixing device 1 is set as a first fixing member 11 and a second fixing member 12, and the second fixing member 12 is vertically installed on the first fixing member 11 to facilitate the setting of the slide groove 6 and to match the other members. This structural setting method has a reasonable layout and is convenient for installing the drive mechanism 2, the first connecting component 3 and the second connecting component 4, and the structure is stable after installation.

[0053] It should be noted that the present invention does not impose any limitations on the specific structures of the first and second fixing members 11, 12. In practical applications, those skilled in the art may customize the structures of the first and second fixing members 11, 12 based on actual needs. For example, the first and second fixing members 11, 12 may be configured as fixing plates, or the first fixing member 11 may be configured as a fixing frame, and the second fixing member 12 may be configured as a fixing plate, and so on. Such flexible adjustments and modifications do not deviate from the basic principles and scope of the present invention and are intended to be within the scope of protection of the present invention.

[0054] It should be noted that the present invention does not impose any restrictions on the specific structure of the chute 6. As long as the first sliding member 7 slides along the chute 6, the second connecting component 4 can drive the barrel cover 5 to move vertically and flip in sequence during the process of opening the cover. In actual applications, those skilled in the art can set the structure of the chute 6 according to actual needs.

[0055] Preferably, if Figures 1 to 3 As shown, the slide groove 6 includes a first slide groove 61 and a second slide groove 62, and the first sliding member 7 includes a first sub-sliding member 71 and a second sub-sliding member 72. The first sub-sliding member 71 is located in the first slide groove 61 and can slide along the first slide groove 61. The second sub-sliding member 72 is located in the second slide groove 62 and can slide in the second slide groove 62. The first slide groove 61 includes a vertical straight segment 611 and an arc segment 612. The bottom of the arc segment 612 is connected to the top of the vertical straight segment 611. The second slide groove 62 is arranged parallel to the vertical straight segment 611, and the two are arranged at the same height.

[0056] Among them, when the first sub-sliding member 71 slides along the vertical straight section 611, the second sub-sliding member 72 slides along the second sliding groove 62, thereby driving the barrel cover 5 to move vertically; when the first sub-sliding member 71 slides along the circular arc section 612, the second sub-sliding member 72 is located at the top of the second sliding groove 62, and the second connecting component 4 rotates with the second sub-sliding member 72 as the rotating axis, thereby driving the barrel cover 5 to flip over.

[0057] By setting the slide groove 6 as the first slide groove 61 and the second slide groove 62, setting the first sliding member 7 as the first sub-sliding member 71 and the second sub-sliding member 72, and setting the first slide groove 61 as a connected vertical straight segment 611 and a circular arc segment 612, this structural setting method enables the first sliding member 7 to effectively achieve vertical movement and flipping during the sliding process in the slide groove 6, thereby opening the barrel cover 5; in addition, this structural setting method has a simple structure and is easy to produce, prepare and assemble. At the same time, the slide groove 6 has a guiding and limiting effect on the first sliding member 7, so that the second connecting component 4 can smoothly drive the barrel cover 5 to move vertically and flip, making the opening and closing operations more convenient.

[0058] It should be noted that the present invention does not impose any limitations on the specific structures of the first and second sub-sliding members 71, 72. In practical applications, those skilled in the art may customize the structures of the first and second sub-sliding members 71, 72 based on actual needs. For example, the first and second sub-sliding members 71, 72 may be configured as sliding posts, or as rollers, etc. Such flexible adjustments and modifications do not deviate from the basic principles and scope of the present invention and are intended to be within the scope of protection of the present invention.

[0059] Preferably, the second end of the first connecting component 3 can perform telescopic movement relative to the first end of the first connecting component 3 .

[0060] By enabling the second end of the first connecting component 3 to perform telescopic movement relative to the first end of the first connecting component 3, under the drive of the driving mechanism 2, the first connecting component 3 can smoothly drive the second connecting component 4 to move during the rotation process, and then smoothly drive the first sliding member 7 to move vertically along the slide groove 6 and then flip over.

[0061] It should be noted that the present invention does not impose any restrictions on the specific structure of the first connecting component 3. As long as the second end of the first connecting component 3 can perform telescopic movement relative to the first end of the first connecting component 3, in actual applications, those skilled in the art can set the structure of the first connecting component 3 according to actual needs.

[0062] As a preferred embodiment, Figure 4 and Figure 5 As shown, the first connecting component 3 includes a first connecting member 31 and a second connecting member 32, the first end of the first connecting member 31 is drivingly connected to the driving mechanism 2, and the second end of the second connecting member 32 is pivotally connected to the second connecting component 4; the first end of the second connecting member 32 is slidingly connected to the first connecting member 31, and the first end of the second connecting member 32 can slide between the first end and the second end of the first connecting member 31.

[0063] The first connecting component 3 is configured as a first connecting member 31 and a second connecting member 32 , and the first end of the second connecting member 32 is able to slide between the first end and the second end of the first connecting member 31 . The structure is simple and easy to assemble and use.

[0064] It should be noted that the present invention does not impose any restrictions on the specific structure of the first connecting member 31 and the second connecting member 32. As long as the first connecting member 31 can slide or telescopically move relative to the second connecting member 32 along the length direction of the first connecting component 3, in actual applications, technicians in this field can set the structure of the first connecting member 31 and the second connecting member 32 according to actual needs.

[0065] Preferably, if Figure 4 and Figure 5 As shown, the first connecting member 31 includes a connecting block 311 and a guide column 312, and the second connecting member 32 includes a slider 321 and a transmission arm 322. The first end of the connecting block 311 is drive-connected to the driving mechanism 2, and the second end of the connecting block 311 is fixedly connected to one end of the guide column 312. The other end of the guide column 312 passes through the slider 321 and extends toward the second connecting component 4. The slider 321 can slide along the guide column 312. The first end of the transmission arm 322 is fixedly connected to the slider 321, and the second end of the transmission arm 322 is pivotally connected to the second connecting component 4.

[0066] The first connecting member 31 is set as a connecting block 311 and a guide column 312, and the second connecting member 32 is set as a slider 321 and a transmission arm 322. The guide column 312 provides a guide for the slider 321, so that the slider 321 slides along the guide column 312. This setting method has a simple structure, and the second connecting member 32 moves more smoothly relative to the first connecting member 31, which is easy to use.

[0067] Preferably, if Figure 5 As shown, the first connecting member 31 further includes a limiting block 313 , which is fixedly connected to the other end of the guide post 312 , thereby limiting the slider 321 between the connecting block 311 and the limiting block 313 .

[0068] By providing the limiting block 313 , the slider 321 can be restricted between the connecting block 311 and the limiting block 313 , thereby effectively preventing the slider 321 from being separated from the guide post 312 during the sliding process.

[0069] Although in the above introduction, the first connecting member 31 is set as a connecting block 311 and a guide column 312, and the second connecting member 32 is set as a slider 321 and a transmission arm 322, this should not limit the scope of protection of the present invention. As long as the first connecting member 31 can slide relative to the second connecting member 32, in actual application, those skilled in the art can set the first connecting member 31 and the second connecting member 32 to other structures. For example, the first connecting member 31 can be set as a first slide rail, and the second connecting member 32 can be set as a second slide rail and a limiting ring block. The first slide rail and the second slide rail are engaged and can slide relative to each other. The limiting ring block is set on the outside of the first slide rail and the second slide rail, and can limit the movement of the first slide rail relative to the second slide rail along its width and thickness direction. Such flexible adjustment and change do not deviate from the basic principle and scope of the present invention and should be limited within the scope of protection of the present invention.

[0070] Furthermore, although the first connecting component 3 is configured as a first connecting member 31 and a second connecting member 32 in the above description, and the first end of the second connecting member 32 is configured to slide between the first end and the second end of the first connecting member 31, this does not limit the scope of protection of the present invention. In actual applications, those skilled in the art may configure the first connecting component 3 with other structures. For example, the first connecting component 3 may be configured as an elastic member that can expand and contract along the length direction, etc. Such flexible adjustments and changes do not deviate from the basic principles and scope of the present invention and should be within the scope of protection of the present invention.

[0071] Preferably, if Figure 2 、 Figure 3 and Figure 5 As shown, the cover opening mechanism of the present invention also includes a supporting member 8 arranged on the fixing device 1, and a circular arc groove 81 is provided on the supporting member 8. A second sliding member 9 is provided on the connecting block 311. The second sliding member 9 is located in the circular arc groove 81 and can slide along the circular arc groove 81. The second sliding member 9 can slide along the circular arc groove 81 during the rotation of the first connecting component 3, so that the supporting member 8 supports the first connecting component 3.

[0072] By setting a support member 8 and opening an arc groove 81 on the support member 8, and setting a second sliding member 9 on the connecting block 311, the second sliding member 9 is located in the arc groove 81. The second sliding member 9 can slide along the arc groove 81 during the rotation of the first connecting component 3, so that the support member 8 supports the first connecting component 3, so that the first connecting component 3 remains stable during rotation.

[0073] It should be noted that the present invention does not impose any limitations on the specific structure of support member 8. In actual applications, those skilled in the art may customize the structure of support member 8 based on actual needs. For example, support member 8 may be configured as a support plate, or as a support block, etc. Such flexible adjustments and modifications do not deviate from the basic principles and scope of the present invention and are intended to be within the scope of protection of the present invention.

[0074] It should also be noted that the present invention does not impose any limitations on the structure of the second sliding member 9. In actual applications, those skilled in the art can customize the structure of the second sliding member 9 according to actual needs. For example, the second sliding member 9 can be configured as a sliding column, or as a roller, etc. Such flexible adjustments and modifications do not deviate from the basic principles and scope of the present invention and are intended to be within the scope of protection of the present invention.

The transmission shaft 24 is rotatably installed on the fixing device 1, and the driving gear 22 can drive the driven gear 23 and the transmission shaft 24 to rotate under the drive of the driving member 21; one end of the transmission shaft 24 is fixedly connected to the first end of the first connecting component 3, so that when the transmission shaft 24 rotates, the first connecting component 3 can be driven to rotate.

[0076] The driving mechanism 2 is provided with a driving member 21, a driving gear 22, a driven gear 23 and a transmission shaft 24. The driving member 21 drives the driving gear 22 to rotate, and the driving gear 22 drives the driven gear 23 and the transmission shaft 24 to rotate, thereby driving the first connecting component 3 to rotate at the same time; the gear transmission is driven by the driving member 21, the structure is simple, easy to assemble and use, and the cost is low.

[0077] It should be noted that the present invention does not impose any limitations on the specific structure of the drive member 21.
