[0025] The utility model provides Figure 1-5The shown low-temperature resistant diversified turnover box includes a box body 1 and a liquid high-pressure nitrogen cylinder 2. An insulating partition 3 is provided in the box body 1, and a plurality of first strip openings are opened on the insulating partition 3; there are multiple liquid high-pressure nitrogen cylinders 2, and the output ends of the multiple liquid high-pressure nitrogen cylinders 2 are provided with injection pipes 21, and the injection pipes 21 pass through the adjacent first strip openings, and the liquid high-pressure nitrogen cylinders 2 are provided with a rack 4; both ends of the rack 4 are slidably connected to the side wall of the box body 1, and a plurality of first springs are connected between the top of the rack 4 and the inner top wall of the box body 1; a plurality of adjusting devices 5 are rotatably connected to the inner side wall of the box body 1, and the plurality of adjusting devices 5 are engaged with the rack 4 together, and a plurality of storage components 6 are provided at the bottom of the plurality of adjusting devices 5, and the plurality of storage components 6 are all located in the box body 1.
[0026] Specifically, the manual adjustment device 5 can start the internal liquid high-pressure nitrogen cylinder 2 to continuously input liquid low-temperature nitrogen into the box 1, so that the inside of the box 1 can always maintain a low temperature during the waiting time at the transfer station, avoiding the problem of corruption of the transported goods.
[0027] The inner cavity of the box body 1 is connected with a transverse plate 7 , which is located on the top of the heat-insulating partition 3 . The other ends of the multiple adjustment devices 5 are all rotatably connected to the transverse plate 7 .
[0028] In the above description, the transverse plate 7 plays the role of heat insulation, sealing and partitioning the space inside the box body 1.
[0029] The adjusting device 5 includes a rotating rod 51, and a cam 52 and a gear 53 are provided on the outer wall of the rotating rod 51. One end of the cam 52 contacts the storage component 6, and the gear 53 engages with the rack 4. One end of the rotating rod 51 rotates through the side wall of the box body 1 and is connected to the knob 54. The gear 53 is provided with a plurality of tooth grooves with a right-angled cross-section; the bottom of the rack 4 is provided with a plurality of right-angled tooth blocks arranged in an array.
[0030] In the above, when the rack 4 is engaged with the gear 53, since the gear blocks are all set with right-angle gear blocks and tooth grooves, when the spring pushes the rack 4 and the gear 53 to engage, it can play a one-way positioning role, so that the rotation angle of the cam 52 can be positioned, so that the cam 52 can limit the pressure plate 62, prompting the pressure plate 62 to squeeze the injection button on the top of the liquid high-pressure nitrogen cylinder 2, thereby ensuring the continuous output of cold air.
[0031] The storage component 6 includes a placement frame 61, the bottom end of the placement frame 61 is connected to the bottom wall of the box body 1, one side of the placement frame 61 is connected to the insulation partition 3, and one side of the placement frame 61 is provided with a placement port that cooperates with the liquid high-pressure nitrogen cylinder 2, and the other side of the storage component 6 is provided with a second strip opening that is consistent with the position of the first strip opening on the insulation partition 3, and the injection pipe 21 also passes through the second strip opening; a pressure plate 62 is provided on the top of the placement frame 61, and an arc-shaped protrusion that cooperates with the cam 52 is provided on the top of the pressure plate 62, and a plurality of second springs are connected between the bottom of the pressure plate 62 and the placement frame 61, and a plurality of array-arranged through-holes are provided on the pressure plate 62, and the limit rods 63 are slid through the through-holes, and one end of the plurality of limit rods 63 is connected to the placement frame 61.
[0032] In the above description, the pressure plate 62 is pushed by the elastic force of the second spring, so that the cam 52 can reset itself when the pressure plate 62 is not pushed, thereby avoiding the situation where the liquid high-pressure nitrogen cylinder 2 is squeezed by gravity.
[0033] One side of the box body 1 is provided with multiple door openings that cooperate with the placement opening of the placement frame 61, and each of the door openings is provided with a sealed door 11. The inner wall of the placement opening is provided with multiple symmetrically arranged grooves, and each groove is provided with a positioning component 64; the positioning component 64 includes a card plate 641 and an elastic telescopic rod 642, one side of the card plate 641 is arranged in an arc shape, and the other side of the card plate 641 is arranged in an inclined surface, and there are two elastic telescopic rods 642, one end of the two elastic telescopic rods 642 is connected to the side wall of the card plate 641, and the other end of the elastic telescopic rod 642 is connected to the inner wall of the groove.
[0034] In the above, the arc-shaped setting of the clamping plate 641 can better fit with the surface of the liquid high-pressure nitrogen cylinder 2, and the inclined surface setting enables personnel to place the liquid high-pressure nitrogen cylinder 2 only by manually pushing the liquid high-pressure nitrogen cylinder 2, so that the surface of the liquid high-pressure nitrogen cylinder 2 fits with the inclined surface, pushing the clamping plate 641 to contract to achieve clamping, reducing the difficulty of installation while improving the firmness after clamping.
[0035] This utility works as follows:
[0036] First, open the sealed door 11, place multiple liquid high-pressure nitrogen cylinders 2 in the placement frame 61, and fix the liquid high-pressure nitrogen cylinders 2 by the elastic push of the elastic telescopic rod 642. After completion, close the sealed door 11, and then manually rotate one of the knobs 54. When the knob 54 is manually rotated, the rotating rod 51, the gear 53 and the cam 52 are driven to rotate. The first spring on the rack 4 pushes the gear 53 to limit the position, and the cam 52 pushes the pressure plate 62, which pushes the injection button on the top of the liquid high-pressure nitrogen cylinder 2, so that the nitrogen in the liquid high-pressure nitrogen cylinder 2 is continuously sprayed into the box body 1 through the injection pipe 21. Since the temperature of the liquid nitrogen is low when it is released from the high-pressure liquid high-pressure nitrogen cylinder 2, it can continuously cool the items in the box body 1;
[0037] At this time, the personnel can judge the internal temperature by observing the temperature displayed on the temperature display 13. When the liquid nitrogen in the opened liquid high-pressure nitrogen cylinder 2 is released, the internal temperature rises. The personnel can continue to cool the box 1 by rotating the other knob 54 to ensure that the interior is continuously kept at a low temperature.
[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
