[0029] The rack unit is used to store the equipment and tools that need to be stored, and the top of the rack unit is provided with a protective connecting cover 2. The protective connecting cover 2 is used to seal the top space of the rack unit to protect the stored equipment and tools. The four corners of the upper surface of the protective connecting cover 2 are welded with top cover clips 17, which correspond to the positioning clips 21.

[0030] The frame unit includes a support base plate 13, a foldable rubber sleeve 14, and a top protective frame plate 15. The top protective frame plate 15 is fixedly connected to the top of the foldable rubber sleeve 14, and the foldable rubber sleeve 14 is fixedly connected to the upper surface of the support base plate 13. The distance between the support base plate 13 and the top protective frame plate 15 can be adjusted by extending and folding the foldable rubber sleeve 14.

[0031] Fixed connecting arms 8 are fixedly installed at both ends of the lower surface of the bearing base plate 13. A bidirectional threaded rod 9 is rotatably installed between the two fixed connecting arms 8. Both ends of the bidirectional threaded rod 9 pass through the fixed connecting arms 8 and extend outward. A control handle is fixedly installed at the extended end.

[0032] Both ends of the bidirectional threaded rod 9 are threaded with bottom support arms 11, and the top of both ends of the bottom support arms 11 are fixedly connected with limit blocks 12; the bottom support arms 11 slide against the lower surface of the bearing base plate 13, and the limit blocks 12 slide against both sides of the bearing base plate 13.

[0033] Two rotating connecting seats 18 are symmetrically installed at both ends of the lower surface of the top protective frame plate 15. A rotating pin is fixedly connected to the side of the rotating connecting seat 18 away from the foldable rubber sleeve 14, and a support connecting arm 19 is rotatably installed on the rotating pin.

[0034] Rotating pins are rotatably mounted on the bottom ends of multiple supporting connecting arms 19. Multiple rotating pins are welded to the two ends of two bottom supporting arms 11 respectively. Guide slides 10 are fixedly installed at both ends between the two fixed connecting arms 8. The guide slides 10 pass through the bottom supporting arms 11 and are slidably connected to the bottom supporting arms 11.

[0035] The four corners of the lower surface of the top protective frame plate 15 are fixedly connected with mating inserts 16. The inner cavity of the mating inserts 16 passes through the top protective frame plate 15 and corresponds to the positioning pins 21.

[0036] The bottom ends of the two fixed connecting arms 8 are fixedly installed with load-bearing connecting plates 3 by bolts. Both ends of the load-bearing connecting plates 3 are integrally formed with downwardly bent end brackets 4. Both ends of the lower surface of the end brackets 4 are welded with fixing clips 5. The four fixing clips 5 are respectively fixedly clamped to the outside of the four positioning clips 21.

By rotating the bidirectional threaded rod 9 clockwise, the two bottom support arms 11 are controlled to move away from each other. Then, the support connecting arm 19 drives the top protective frame plate 15 to slide upward along the axis of the guide connecting post 20, increasing the accommodating space of the frame unit. Then, one frame unit is placed on top of the other frame unit, so that the fixing sleeve 5 of the upper frame unit is engaged with the mating sleeve 22 of the lower frame unit.

[0042] When assembling the frame unit with the mobile base 1, the fixing sleeve 5 of the frame unit is engaged above the positioning pin 21;

[0043] When the frame unit is engaged with the protective connecting cover 2, the engaging clip 22 is inserted into the top cover clip 17.
