[0003] After searching, the publication number is: CN219867391U, which discloses a portable liquid oxygen storage tank, which is equipped with a pull rod assembly and rollers, and can be pulled and slid on the ground to save manpower; at the same time, an elastic support assembly with damping is set in the second inner tank, so that the cryopreservation tube can slowly extend upward after the bottle cap is opened, which is convenient for collection. Liquid oxygen storage tanks are usually divided into vertical and horizontal types to meet the needs of different users. The liquid oxygen storage tank in the horizontal state has a lower center of gravity and is more stable, but the above-mentioned prior art cannot make the outer tank body tip over and maintain the horizontal state. If the outer tank body is tipped over, the internal cryopreservation tube will collide and be damaged, and the application range of the outer tank body is relatively narrow.

[0004] In order to solve the above problems, the utility model provides a horizontal liquid oxygen storage tank. Utility Model Content

[0026] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments:

[0028] After the tank cover 4 is screwed off from the transport tank body 1, the four electric telescopic rods 8 are started so that their telescopic ends jointly push the placement plate 9 to lift up to the bottle mouth 3. When the limiting plate 21 protrudes out of the bottle mouth 3, the liquid oxygen storage tank body 23 is passed through the limiting hole 22 and the bottom end of the liquid oxygen storage tank body 23 enters the tank groove 15. When the four liquid oxygen storage tank bodies 23 are all located between the limiting hole 22 and the tank groove 15, the self-locking motor 10 is started, and the output end of the self-locking motor 10 drives the driving gear 12 to make the four driven gears 13 mesh and rotate.

The walls move relative to each other, so that the two clamping plates 18 on the moving groove 16 are driven by the moving block 17 to relatively press the side walls of the liquid oxygen storage tank body 23 in the tank tank 15 to fix it in the tank tank 15. When the two moving blocks 17 in the four moving grooves 16 are relatively pressed against the side walls of the liquid oxygen storage tank body 23 in the tank tank 15 to achieve limited fixation, the tank cover 4 is used to seal the bottle mouth 3 and then the transport tank body 1 is tilted, so that the four cushion blocks 24 are in contact with the ground and the transport tank body 1 is placed horizontally through the two horizontal handles 7, thereby improving the application range of the transport tank body 1. When the liquid oxygen storage tank body 23 in the transport tank body 1 needs to be used, it can be connected to the liquid oxygen storage tank body 23 inside by only using the bottle mouth 3.

[0032] By providing an anti-collision pad designed as an annular pad, the liquid oxygen storage tank body 23 in the limiting hole 22 will not collide with the inner wall of the limiting hole 22 during transportation or when the transport tank body 1 is tilted to a horizontal state, thereby causing damage to the liquid oxygen storage tank body 23;

[0033] Furthermore, a plurality of rollers 2 are provided at the lower end of the transport tank body 1 .

[0034] By providing a plurality of rollers 2, the plurality of rollers 2 can be matched with the pull rod assembly 6 to realize the movement of the transport tank 1 on the ground in a vertical state;

[0035] Furthermore, the diameters of the limiting plate 21 and the placing plate 9 are both smaller than the diameter of the bottle mouth 3 .

[0036] By setting the diameter of the limiting plate 21 and the placing plate 9 to be smaller than the diameter of the bottle mouth 3, the limiting plate 21 and the placing plate 9 can both rise to the outside of the transport tank body 1 through the bottle mouth 3, which facilitates the maintenance of the limiting plate 21 and the placing plate 9 and prolongs their service life;

[0037] Furthermore, one end of the four bidirectional threaded rods 14 away from the driving gear 12 is rotatably connected to the inner walls of the four moving grooves 16 respectively, and the plurality of moving blocks 17 are slidably connected to the inner walls of the four moving grooves 16 respectively.

[0038] By making the ends of the four bidirectional threaded rods 14 away from the driving gear 12 rotatably connected to the inner walls of the four moving grooves 16, the ends of the four bidirectional threaded rods 14 away from the driving gear 12 can be rotated on the inner walls of the four moving grooves 16, and by making the multiple moving blocks 17 slidably connected to the inner walls of the four moving grooves 16, the multiple moving blocks 17 can slide in the matching moving grooves 16.

[0040] Further, the manufacturer of the electric telescopic rod 8 is Hebei Demai Transmission Machinery Co., Ltd., and the model is DMDT;

[0041] Furthermore, the roller 2, the tank cover 4, the connecting piece 5, and the pull rod assembly 6 have been fully disclosed in the publication number: CN219867391U, and will not be described in detail here.

[0042] The working principle of the utility model is as follows: first, the tank cover 4 is screwed off from the transport tank body 1, and then the four electric telescopic rods 8 are started so that their telescopic ends jointly push the placement plate 9 to lift up to the bottle mouth 3. When the limiting plate 21 protrudes out of the bottle mouth 3, the liquid oxygen storage tank body 23 is passed through the limiting hole 22 and the bottom end of the liquid oxygen storage tank body 23 enters the tank groove 15. When the four liquid oxygen storage tank bodies 23 are all located between the limiting hole 22 and the tank groove 15, the self-locking motor 10 is started, and the output end of the self-locking motor 10 drives the driving gear 12 to make the four driven gears 13 mesh and rotate, and the four driven gears 13 respectively drive the four bidirectional threaded rods 14 to rotate, and through the threads on the bidirectional threaded rods 14, the two moving blocks 17 are moved along the moving blocks 17 on the bidirectional threaded rods 14. The inner walls of the grooves 16 move relative to each other, so that the two clamping plates 18 on the movable grooves 16 are driven by the moving blocks 17 to relatively press the side walls of the liquid oxygen storage tank body 23 in the tank groove 15 to fix it in the tank groove 15. When the two moving blocks 17 in the four movable grooves 16 are relatively pressed against the side walls of the liquid oxygen storage tank body 23 in the tank groove 15 to achieve limited fixation, the tank cover 4 is used to seal the bottle mouth 3 and then the transport tank body 1 is tilted, so that the four cushion blocks 24 are in contact with the ground and the transport tank body 1 is placed horizontally through the two horizontal handles 7, thereby improving the application range of the transport tank body 1. When the liquid oxygen storage tank body 23 in the transport tank body 1 needs to be used, it can be connected to the liquid oxygen storage tank body 23 inside through the bottle mouth 3.

At this time, the transport tank body 1 is tilted again, so that the four pads 24 are in contact with the ground and the transport tank body 1 is placed horizontally through the two horizontal handles 7.
