[0026] See also Figure 1-5A bottom frame assembly includes a bottom frame assembly complete body 1, wherein the bottom frame assembly complete body 1 is composed of a plurality of horizontally spliced ​​connecting frames 10 (two in the figure); coaxial moving grooves 20 are respectively opened at the upper and lower sides and the left and right ends of the connecting frame 10, the length lines of the two moving grooves 20 on the same side of the connecting frame 10 are located on the same straight line, and a preset gap is set between the two moving grooves 20, and the upper and lower sides of the two moving grooves 20 on the left side are rotatably connected with bidirectional threaded rods 21, and the upper and lower sides of the bidirectional threaded rods 21 are respectively threadedly connected A sliding block 22 is connected, and a support frame 23 is fixedly connected to the right side of the sliding block 22, and a screw limiter is arranged inside the connecting frame 10; guide rods 25 are fixedly connected to the upper and lower sides of the two movable grooves 20 on the right side, and the axis of the guide rod 25 is parallel to the length line of the movable groove 20, and the upper and lower sides of the guide rod 25 are respectively slidably connected to moving blocks 26, and the left side of the moving block 26 is fixedly connected to the corresponding support frame 23; the opposite ends of the two bidirectional threaded rods 21 are connected; the interior of the support frame 23 is fixedly connected with longitudinal and transverse reinforcing ribs 24.

[0027] In this embodiment, two groups of upper and lower connecting support frames 23 are provided on the same connecting frame 10, and one group of support frames 23 is provided along the upper and lower sides of the connecting frame 10. When adjusting, only one of the two-way threaded rods 21 needs to be rotated. Since the two two-way threaded rods 21 are fixed together, the two two-way threaded rods 21 can rotate in the same direction, thereby driving the two support frames 23 of the same group to move toward or away from each other, thereby achieving the effect of facilitating the position adjustment of the support frames 23 on the same side. After adjustment, the two-way threaded rod 21 is fixed by the screw limiter, so that the two-way threaded rod 21 will not rotate again under the action of external force without releasing the limit of the two-way screw 21 by the screw limiter. The support frame 23 is flush with the top water surface of the connecting frame 10, and the support frame 23 cooperates with the connecting frame 10 to support the container when in use.

[0028] As a preferred embodiment, a group of cross support blocks 40 are fixedly connected to the bottom of the connecting frame 10. The cross support blocks 40 are in an "X" shape.

When in use, multiple connecting frames 10 are horizontally fitted together, and then the plug-in blocks 12 are inserted into the two fixing grooves 11 of adjacent connecting frames 10, so as to facilitate the left-right connection of multiple connecting frames 10.

[0030] After the bidirectional threaded rod 21 is adjusted, if the bidirectional threaded rod 21 is not restricted, the bidirectional threaded rod 21 may flip due to natural rotation or wind rotation, thereby causing the adjusted support frame 23 to shift in position, so a positioning structure is proposed.

[0032] In this embodiment, when the support frame 23 needs to be adjusted, it is only necessary to rotate the flip rod 31, and the flip rod 31 drives the bidirectional threaded rod 21 to rotate; and when the support frame 23 is adjusted, the left positioning groove 321 of the positioning ring 32 is opposite to the positioning block 37, and then by rotating the stud 34, the stud 34 rotates and moves to the right, driving the positioning plate 36 to move to the right through the bearing 35, until the positioning block 37 is inserted into the positioning groove 321, thereby achieving the restriction of the positioning ring 32 and the flip rod 31.

[0033] As a preferred manner, the positioning groove 321 is matched with the positioning block 37 in shape, so that the positioning block 37 can be completely inserted into the positioning groove 321, thereby preventing the flip rod 31 from shaking after being positioned.

[0034] As a preferred embodiment, the upper and lower ends of the right side of the fixing plate 33 are respectively fixedly connected with hollow tubes 38, the interior of the hollow tube 38 is slidably connected with an extension tube 39, and the right side of the extension tube 39 is fixedly connected to the left side surface of the positioning plate 36; when the positioning plate 36 moves, the positioning plate 36 drives the two extension tubes 39 to move in the same direction, and at the same time the extension tube 39 slides along the inside of the hollow tube 38, thereby achieving the effect of guiding the positioning plate 36 when it moves.
