[0056] In this way, the structural stability and reliability of the main body frame are improved, and at the same time, the bottom plate 3 can smoothly perform the lifting action.

[0057] As an optional implementation, the bottom plate 3 is provided with a supporting plate 9 at each of the four corners of the bottom.

[0058] Further, the supporting plate 9 is bolted to the bottom plate 3.

[0059] The supporting plate 9 is used to support the bottom plate 3, enhance the bearing capacity of the bottom plate 3, and also can transmit the lifting action of the bottom plate 3 to the drive part through the conduction part, so that the lifting action of the bottom plate 3 is more stable and smooth.

[0060] As an optional implementation, the column 1 is recessed inwardly near one side of the bottom plate 3 to form a recess 11, and the bottom plate 3 and the supporting plate 9 are both adapted to the recess 11 and in sliding abutment with the recess 11.

[0061] The recess 11 can provide a sliding track for the bottom plate 3 and the supporting plate 9, so that the lifting action is more smooth. At the same time, it also plays a certain guiding and limiting role, avoiding the offset or shaking of the bottom plate 3 during lifting.

[0062] As an optional implementation, the transmission part includes a guide slider 7, a transmission member 6 and a guide wheel 8, the guide slider 7 is connected with the guide wheel 8 through the transmission member 6; the guide slider 7 is arranged in the accommodating cavity 13 and in sliding fit with the accommodating cavity 13; the guide wheel 8 is arranged outside the column 1 and in rolling fit with the outer wall surface of the recess 11; the transmission member 6 is connected with the free end of the driving part, and the fixed end of the driving part is connected with the accommodating cavity 13.

[0063] Through the sliding fit of the guide slider 7 and the accommodating cavity 13, the vertical direction guiding for the lifting action of the bottom plate 3 is provided.

[0064] Through the rolling fit of the guide wheel 8 and the recess 11, the direct contact area with the column 1 is reduced, so that the lifting action of the bottom plate 3 is more smooth.

[0065] As an optional implementation, the transmission member 6 includes a first transmission part 61, a second transmission part 62 and a third transmission part 63, the first transmission part 61 and the third transmission part 63 are respectively arranged in vertical to the second transmission part 62 in Z type. A sliding groove 12 is formed on the recess 11, the sliding groove 12 is arranged parallel to the lifting direction of the bottom plate 3 and in communication with the accommodating cavity 13, and the second transmission part 62 is in sliding fit with the sliding groove 12; the first transmission part 61 is connected with the free end of the driving part, and the guide slider 7 is arranged on the first transmission part 61; the third transmission part 63 is connected with the supporting plate 9, and the guide wheel 8 is arranged on the third transmission part 63.

[0066] Further, the driving part adopts a compression linear spring 4, the fixed end of the compression linear spring 4 is connected with the lower end surface of the accommodating cavity 13, and the free end of the compression linear spring 4 is connected with the first transmission part 61. The guide slider 7 is sleeved on the first transmission part 61. The height of the second transmission part 62 is greater than or equal to the overall height of the driving part in the fully compressed state.

[0067] Compared with the prior art, the key elements such as the spring still occupy a certain space in the compressed state, the bottom space is still not completely released, the bottom plate cannot be lowered to the bottom of the box, and the complexity and manufacturing cost of the box are increased. The utility model discloses a transmission part 6 and a compression linear spring 4 are cooperated, and more efficient space utilization is realized. The compression linear spring 4 is arranged in the containing cavity 13 of the stand column 1, and does not occupy the space of the bottom of the box. When the compression linear spring 4 is in the fully compressed state with a certain height, the bottom plate 3 can be lowered to the bottom of the box due to the arrangement of the transmission part 6, more bottom space is released, and the storage space is greatly increased.

[0068] As shown in Figure 2 , Figure 3 , in the idle state of the bottom plate 3, the bottom plate 3 is automatically pushed to the upper limit due to the pre-tightening force of the compression linear spring 4. At this time, the guide sliding block 7 is in abutment with the upper end face of the containing cavity 13, and the compression linear spring 4 is in a natural state.

[0069] With the gradual addition of the articles, the bottom plate 3 slowly sinks under the gradually increasing gravity and transmits the third transmission part 63 of the transmission part 6 to the second transmission part 62 in the sliding groove 12 through the supporting plate 9, drives the first transmission part 61 to move downward along the containing cavity 13, and gradually compresses the compression linear spring 4, so that more storage space is released to accommodate more articles.

[0070] As shown in Figure 4 , Figure 5 , when the bottom plate 3 is lowered to the lower limit, the total weight of the bottom plate 3 and the articles reaches the maximum, at this time, the second transmission part 62 is in abutment with the lower end face of the sliding groove 12, and the compression linear spring 4 is in a fully compressed state.

[0071] In the process of taking the articles, with the decrease of the number of the articles of the bottom plate 3, the gravity borne by the bottom plate 3 also correspondingly decreases, the compression linear spring 4 releases the stored elastic potential energy, and drives the bottom plate 3 to automatically and stably rise to the upper limit, waiting for the next article storage operation.

[0072] As an optional implementation, a limiting protrusion 131 is arranged on the inner wall surface of the containing cavity 13, the limiting protrusion 131 is arranged parallel to the lifting direction of the bottom plate 3, and a limiting groove 71 is arranged on the guide sliding block 7 and matched with the limiting protrusion 131.

[0073] Further, the limiting groove 71 and the limiting protrusion 131 are arranged parallel to the lifting direction of the bottom plate 3.

[0074] The locking engagement between the limiting groove 71 and the limiting protrusion 131 ensures that the guide slider 7 slides along the preset path during the lifting and lowering process, thereby further improving the accuracy and stability of the guide.

[0075] As an alternative implementation, the guide wheels 8 are symmetrically arranged on both sides of the third transmission unit 63.

[0076] This design makes the guiding force provided by the guide wheel 8 more balanced, improving the smoothness and reliability of the lifting action.

[0077] Example 2:

[0078] The difference between Example 2 and Example 1 is as follows: Figures 6-7 As shown, the driving unit uses a tension linear spring 5. The fixed end of the tension linear spring 5 is connected to the upper end face of the receiving cavity 13, and the free end of the tension linear spring 5 is connected to the first transmission unit 61. The guide slider 7 is sleeved on the first transmission unit 61 and is positioned close to the tension linear spring 5.

[0079] The height of the second transmission unit 62 can be designed to be relatively short so that when the linear spring 5 is stretched to its maximum extension length, the base plate 3 can fall smoothly to the bottom of the column 1, thereby maximizing the storage space of the box.

[0080] like Figure 6 As shown, when the base plate 3 is in an unloaded state, due to the contraction force of the tension linear spring 5, the base plate 3 is automatically pulled up to its upper limit. At this time, the tension linear spring 5 is in a contracted state.

[0081] As items are gradually added, the base plate 3 slowly sinks under the increasing gravity and is transmitted to the third transmission part 63 of the transmission component 6 through the support plate 9. This drives the second transmission part 62 to slide in the slide groove 12, and the first transmission part 61 also moves downward along the receiving cavity 13 and gradually stretches the linear spring 5, thereby releasing more storage space to accommodate more items.

[0082] like Figure 7 As shown, when the base plate 3 descends to its lower limit, the total weight of the base plate 3 and the item reaches its maximum. At this time, the second transmission part 62 abuts against the lower end face of the slide groove 12, and the tension linear spring 5 is fully stretched to its maximum tension length.

[0083] During the item retrieval process, as the number of items on the base plate 3 decreases, the gravity on the base plate 3 also decreases accordingly. The stretched linear spring 5 releases the stored elastic potential energy, causing the base plate 3 to automatically and smoothly rise to the upper limit position, waiting for the next item storage operation.
