[0001] The present invention relates to the technical field of packaging bases, and more particularly to a packaging base which is convenient for loading and unloading. Background Art

[0002] The main function of the packaging base is to ensure that the packaging can remain stable and safe during delivery, storage, transportation and use. The biological safety cabinet is a key equipment used in the laboratory to handle potentially infectious materials or other hazardous substances. It provides a protected working environment by controlling air flow. There will be a support frame, casters and feet at the bottom of the biological safety cabinet. When transporting the biological safety cabinet, the manufacturer usually fixes the biological safety cabinet to the packaging base, which is connected to the support frame and leaves the casters in a suspended state, in order to ensure the stability of the equipment during transportation.

[0003] However, currently, multiple workers are required to lift equipment such as biological safety cabinets onto and off the packaging base, requiring the workers to carry the equipment to move, which makes loading and unloading very inconvenient, time-consuming and labor-intensive, and easily causes injuries to the workers. Currently, inclined plates are placed to allow the cabinet to slide onto or off the packaging base, but there is no corresponding fixation, which may easily cause the inclined plate to deviate and fall, causing damage to the cabinet. Alternatively, screws are used for fixing, which requires a large number of screws, has high labor intensity, and has low operating efficiency.

[0004] Therefore, it is necessary to provide a packaging base that is easy to load and unload to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a packaging base that is easy to load and unload to solve the above technical problems.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] See also Figure 1-10 A packaging base that is easy to load and unload is used to support a cabinet 1. A support frame 2 and casters 3 are provided at the bottom of the cabinet 1, including:

[0045] A bottom plate 4 is provided with a plurality of connecting plates 5, and two connecting plates 5 are provided on the bottom plate 4. Both sides of each connecting plate 5 are provided with vertical plates 6.

[0046] The support guide plate 7 is used to support the support frame 2. The upper end and side surfaces of the vertical plate 6 are provided with fixing components 8 for fixing the support guide plate 7;

[0047] The shift plate 9 is slidably arranged on the connecting plate 5;

[0048] The connecting component 10 is arranged on the supporting guide plate 7 and is used to connect the moving plate 9 and the supporting guide plate 7 .

[0049] When in use, when preparing to place the cabinet 1 on the packaging base, first place the support guide plate 7 on the end of the connecting plate 5, and fix the support guide plate 7 through the fixing component 8 at this position on the vertical plate 6. At this time, the other end of the support guide plate 7 contacts the ground, and the support guide plate 7 is in an inclined state. Then translate the shift plate 9 to slide along the connecting plate 5, and finally make the shift plate 9 in the position of the support guide plate 7. After the shift plate 9 moves into place, it will be connected to the support guide plate 7 through the connecting component 10, that is, the shift plate 9 will also be restricted and fixed in this position. Then the staff drives the cabinet 1 to move through the casters 3, so that the casters 3 move up along the support guide plate 7 and finally move to the shift plate 9. Then remove the support guide plate 7 on the connecting plate 5, and then lift the cabinet 1 in the vertical direction for a short distance. The support guide plate 7 can be placed on the corresponding position on the vertical plate 6 by manpower or external force equipment, and the support guide plate 7 can be fixed again by the fixing component 8 at this position on the vertical plate 6; then translate the shift plate 9 so that it is no longer under the caster 3, and then put down the cabinet 1. The support frame 2 of the cabinet 1 will press on the support guide plate 7, and the caster 3 is in a suspended state at this time, that is, the loading of the cabinet 1 is completed. Similarly, when the cabinet 1 is subsequently unloaded from the base of this packaging, after releasing the fixation of the support frame 2, the cabinet 1 is raised, and the shift plate 9 is translated to the bottom of the caster 3, and then the support guide plate 7 above the vertical plate 6 is removed and placed on the end of the connecting plate 5 in an inclined state. After that, the cabinet 1 is put down, and the caster 3 of the cabinet 1 falls on the connecting plate 5. Then move the cabinet 1, and the caster 3 will move along the connecting plate 5 and finally slide off the support guide plate 7.

[0050] In summary, the setting of the packaging base of the present application can conveniently and quickly load and unload the cabinet 1, without the need for the staff to move the cabinet 1 up and down, saving a lot of time and energy, and can also better protect the staff, reduce injuries, and have high safety performance. In addition, the packaging base can not only support the fixed support frame 2 and the cabinet 1 by making dual use of the support guide plate 7, but also can be used as a slope to make the cabinet 1 more convenient to move up and down, with strong flexibility, reducing the use of redundant materials and tools, and having high practicality; the support guide plate 7 can be conveniently and quickly fixed by the fixing component 8, which can ensure the stability of the support guide plate 7 and effectively prevent the support guide plate from being unstable when tilted, causing damage to the cabinet 1. And there is no need for numerous screws, which not only saves time and effort, has high work efficiency, but also reduces the fixing effect of the inclined plate affected by slipping. Through the translation of the shift plate 9, the caster 3 can be switched between a suspended state and a contact moving state, which has good flexibility and can be widely used.

During this process, the limit block 82 will be squeezed by the through hole 11, and the limit block 82 will be retracted into the insertion rod 81 under pressure. When the limit block 82 and the insertion rod 81 completely pass through the through hole 11, the limit block 82 is no longer under pressure, and the limit block 82 will extend from the insertion rod 81 to reset. At this time, the limit block 82 will block and limit the support guide plate 7, and the support guide plate 7 is fixed. When the support guide plate 7 needs to be removed later, the limit block 82 can be pressed to enter the insertion rod 81, and the support guide plate 7 can be moved at the same time so that the limit block 82 appears in the through hole 11, and the support guide plate 7 is continued to be moved. Finally, it will be separated from the insertion rod 81, and the removal of the support guide plate 7 is completed. The operation is simple and convenient, saving time and effort.
