The limit optical axis 902 penetrates through the relay plate 901. An anti-disengagement disk 903 is fixedly arranged at the end of the limit optical axis 902. A lifting control cylinder 904 is fixedly arranged on the relay plate 901. The telescopic shaft of the lifting control cylinder 904 is fixedly installed with the split moving plate 9. The split moving plate 9 is driven to move up and down relative to the relay plate 901 through the lifting control cylinder 904. A rotating machine box 905 is arranged below the relay plate 901. A support rotating shaft 906 is arranged in the rotating machine box 905. The support rotating shaft 906 is fixedly installed with the relay plate 901. The rotating machine box 905 drives the relay plate 901 to rotate through the support rotating shaft 906. The inside of the rotating machine box 905 includes a motor and a reduction gear set. The support rotating shaft 906 is in transmission connection with the reduction gear set. The lower surface of the rotating machine box 905 is fixedly provided with a machine box bottom plate 907. The lower surface of the machine box bottom plate 907 is fixedly provided with an optical axis sleeve 908 and a lead screw sleeve 909.

A track horizontal axis 911 and a driving lead screw 912 are arranged on one side of the installation vertical plate 910. The track horizontal axis 911 penetrates through the optical axis sleeve 908. The driving lead screw 912 is in spiral cooperation with the lead screw sleeve 909. A lead screw motor 913 is arranged at the end of the driving lead screw 912.

[0037] On the lower surface of the split moving plate 9 near both sides, pre-closure table plates 701 are respectively and fixedly arranged. The pre-closure table plates 701 are bent in an L shape. A rubber enclosure 702 is fixedly arranged on the pre-closure table plates 701. The rubber enclosure 702 is made of rubber and is in a C shape. When the pre-closure table plates 701 extend under the interactive operation table 7, the rubber enclosure 702 can be in sealing cooperation with the lower surface of the interactive operation table 7. An L-shaped inner air groove 703 is formed in the interactive operation table 7. One end of the L-shaped inner air groove 703 penetrates downward. An air whistle cylinder 704 is embedded and installed on the inner wall surface of the L-shaped inner air groove 703. Pressure chamber pipes 705 are symmetrically arranged on both sides of the machine box bottom plate 907. The pressure chamber pipes 705 are communicated with the L-shaped inner air groove 703. A piston disk 706 is hermetically and slidably arranged in the pressure chamber pipes 705. An accommodation ring groove 707 is formed on the end surface of the pressure chamber pipes 705.

[0038] A return spring 708 is arranged in the accommodation ring groove 707. The return spring 708 applies a return elastic force to the piston disk 706. Through the support and return of the return spring 708, the pressure chamber pipes 705 suck air through the L-shaped inner air groove 703. A top support plug shaft 709 is fixedly arranged on the side of the piston disk 706 away from the return spring 708. The top support plug shaft 709 passes through the end of the pressure chamber pipes 705 and extends to the outside of the pressure chamber pipes 705. A breathing air hole 710 is formed through the end of the pressure chamber pipes 705. Extrusion vertical plates 711 are respectively and fixedly arranged on the lower surface of the machine box bottom plate 907 near both sides. The extrusion vertical plates 711 can be in extrusion cooperation with the top support plug shaft 709 to push the top support plug shaft 709 to move axially.

[0039] A control panel 101 is installed on the surface of the storage box shell 1. The control panel 101 is used to control the handling mechanism. The handling mechanism includes a first track column 102 and a second track column 103. Both the first track column 102 and the second track column 103 are arranged inside the storage box shell 1. The first track column 102 and the second track column 103 are perpendicular to each other. First walking modules 104 are respectively arranged at both ends of the second track column 103. The second track column 103 can move relative to the first track column 102 through the first walking modules 104. A second walking module 105 capable of moving forward is arranged on the second track column 103. A telescopic module 106 is fixedly arranged on the second walking module 105. A clamping module 107 is fixedly arranged on the telescopic module 106. An outer wall ring rib 108 is fixedly arranged on the surface of the liquid nitrogen storage tank 3. The clamping module 107 clamps the liquid nitrogen storage tank 3 through the outer wall ring rib 108. Both the first walking module 104 and the second walking module 105 adopt the track traveling trolley mechanism in the prior art. The telescopic module 106 is used to control the telescopic movement of the clamping module 107. A clamping claw capable of opening and closing is arranged on the clamping module 107.

[0040] When the present invention is in use, the number of the liquid nitrogen storage tank 3 to be taken out is input through the control panel 101, and the handling mechanism operates. The clamping module 107 clamps the outer wall ring edge 108, clamps and takes out the corresponding liquid nitrogen storage tank 3, and places it on the split moving plate 9. Initially, the locking clip edge 10 and the mating clip edge 11 are docked and matched to form the same clamping track as the positioning clip edge 5. The handling mechanism pushes the liquid nitrogen storage tank 3, so that the clip eaves base 4 at the bottom of the liquid nitrogen storage tank 3 is stuck in the mating clip edge 11 and moves to the locking clip edge 10 through the mating clip edge 11 and is located on the split moving plate 9.

[0041] When anti-theft locking is required, the lead screw motor 913 drives the drive lead screw 912 to rotate, so that the machine box bottom plate 907 drives the rotary machine box 905, the relay plate 901 and the split moving plate 9 to move horizontally synchronously until Figure 7 In the state shown in, at this time, the clip eaves base 4 located in the locking clip edge 10 is blocked by the mating clip edge 11 and cannot slip along the length direction of the locking clip edge 10, thereby realizing the anti-theft locking of the liquid nitrogen storage tank 3.

[0042] When visual inspection of the liquid nitrogen storage tank 3 is required, the lifting control cylinder 904 contracts, so that the split moving plate 9 moves downward. After the split moving plate 9 moves in place, the locking clip edge 10 is located below the interactive operation table 7 and will not interfere with the interactive operation table 7. Then the rotary machine box 905 drives the support rotating shaft 906 to rotate slowly, so that the relay plate 901 and the split moving plate 9 rotate synchronously, and the liquid nitrogen storage tank 3 located above the split moving plate 9 rotates accordingly, so as to be able to perform rotary display for easy inspection.

[0043] In the above process, when the split moving plate 9 moves in the locking moving groove 8 and is respectively docked and closed with both sides of the locking moving groove 8, the extrusion vertical plate 711 will be extrusion-fitted with the top holding plug shaft 709, pushing the top holding plug shaft 709 to move axially, so that the piston disc 706 moves, and the pressure gas in the pressure chamber tube 705 is input into the corresponding side of the L-shaped inner air groove 703. The gas sprays out from the L-shaped inner air groove 703. At this time, the pre-closed table plate 701 just moves to the lower part of the downward opening of the L-shaped inner air groove 703 and is hermetically fitted with the rubber enclosure 702 to guide the airflow sprayed out from the L-shaped inner air groove 703, so that the airflow sprays upward through the gap that is about to be closed between the split moving plate 9 and the side surface of the locking moving groove 8, blowing out sundries such as hair and paper to avoid clamping. At the same time, under the action of air pressure, a part of the airflow will be shunted through the air whistle tube 704 to generate a prompt sound.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
