Detailed Implementation

[0025] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0026] This embodiment provides a foldable seedling steel frame bed, which includes a bed surface 20 and a support frame. The support frame is composed of multiple foldable supports 10 spliced ​​together. It is understood that the specific splicing size and method can be selected according to actual needs (it can be expanded horizontally or vertically) to meet the requirements of large-scale seedling cultivation in this embodiment. In this embodiment, it is preferred that adjacent foldable supports 10 are fixed by binding. The foldable support includes a fixed support 101 and at least one sliding support 102. The fixed support 101 and the sliding support 102 are connected end to end by a slide rail connector 103. At the same time, the sliding support 102 is provided with a track 106 that slides with the slide rail connector 103. Through the cooperation of the slide rail connector 103 and the track 106, the sliding support 102 can be stacked relative to the fixed support 101.

[0027] Specifically, in this embodiment, the foldable support frame is made of stainless steel with a galvanized surface. The hot-dip galvanized layer thickness is greater than or equal to 85μm, which ensures the strength of the steel frame bed and improves its stability and load-bearing capacity. The sliding support 102 constituting the foldable support frame includes one unit, which is connected to the fixed support 101 end-to-end via slide rail connectors 103. Figure 1-3 As shown, in this embodiment, the size of the preferred translation bracket 102 is slightly larger than that of the fixed bracket 101. The size of the unfolded foldable bracket 10 is preferably around 2000×1600×1000mm (L×W×H), and the size of the foldable bracket 10 after stacking and folding is preferably around 1200×1600×400mm (L×W×H). This facilitates disassembly and transportation and significantly reduces the space occupancy rate.

[0028] The bed surface 20 has a mesh structure and its size is adapted to the steel frame bed. The bed surface 20 is covered with detachable connectors such as binding wire, bolts 30 or pins on the upper end of the steel frame bed. Before use, it is ensured that the mesh wire cover has no obvious depressions or protrusions. In this embodiment, the bed surface 20 is preferably a corrugated steel wire bed surface 20, made of 304 stainless steel, with a mesh density of 40X40mm.

[0029] The slide rail connector 103 includes a pulley seat 1031, a connecting rod 1032, and a fixed seat 1033, such as Figure 4-5 As shown, the pulley seat 1031 includes a seat plate 10311 and a pulley 10312. The seat plate 10311 is a rectangular hollow structure with a roller at the front end. The pulley 10312 is disposed in the hollow cavity of the seat plate 10311 and extends to the outside of the seat plate 10311 on both sides, thus facilitating sliding engagement with the track 106 on the translation bracket 102. The fixed seat 1033 is a base structure. The connecting rod 1032 is disposed between the pulley seat 1031 and the fixed seat 1033, and its two ends are respectively hinged to the roller of the pulley seat 1031 and the fixed seat 1033, thereby forming a... The foldable connector is foldable into a Z-shape when folded and into a straight line when unfolded. The fixed base 1033 is preferably fixed to the end of the fixed bracket 101 by bolts 30, and the pulley base 1031 is installed in the track 106 of the translation bracket 102. It can be understood that in this embodiment, after folding into a Z-shape, the distance between the pulley base 1031 and the fixed base 1033 should be greater than the height of the fixed bracket 101, that is, a height difference can be formed between the fixed bracket 101 and the translation bracket 102, so as to facilitate the sliding of the translation bracket 102 and thus achieve stacked folding.

[0030] Understandably, in order to improve stability, a locking element is provided on the fixed base 1033. The locking element includes a locking hole provided on the fixed base 1033 and a matching locking rod 10331. The locking hole is located on at least one side of the hinge point between the fixed base 1033 and the connecting rod 1032. In this embodiment, it is preferably the inner side. The locking rod 10331 can be a screw or a pin, so as to facilitate locking the Z-shaped structure after folding and prevent it from unfolding automatically during movement.

[0031] Specifically, when folding is required, external force is first used to fold the slide rail connector 103 into a Z-shape. At this time, the translation bracket 102 is suspended above the fixed bracket 101. Then, the translation bracket 102 is pushed, and with the cooperation of the pulley seat 1031 and the slide rail, the translation bracket 102 can be moved relative to the fixed bracket 101 until the tail of the translation bracket 102 is close to or flush with the tail of the fixed bracket 101. The locking rod 10331 is used to lock it, and the stacking is completed. When unfolding, the translation bracket 102 is pushed to move in the opposite direction until it reaches the maximum stroke position. At this time, the tail of the translation bracket 102 is connected to the head of the fixed bracket 101. Then, external force is used to push the connecting rod 1032 to rotate relative to the two sets of hinge axes (the hinge points of the pulley seat and the fixed seat 1033) until it is in a horizontal state. Figure 8 As shown, at this time, the translation bracket 102 and the fixed bracket 101 are not only connected end to end, but also aligned, ensuring the stability of subsequent seedling cultivation.

[0032] A track 106 is provided on the translation support 102. The track 106 can accommodate the pulley seat 1031 and can slide with the pulley seat 1031. In this embodiment, the track 106 is preferably arranged on both sides of the translation support 102 along its length direction, and the bottom of the track 106 has an opening that allows the connecting rod 1032 to extend to the outside. Figure 7 As shown; by Figure 7 As can be seen, in this embodiment, the cross-section of the track 106 is T-shaped or C-shaped, which can both support the pulley seat and ensure effective sliding.

[0033] Both the fixed bracket 101 and the sliding bracket 102 include a plate frame 104, which is a frame structure. A support column 105 is provided at the end of the plate frame 104 corresponding to the fixed bracket 101 and the sliding bracket 102 away from the slide rail connector 103; or, a support column 105 is provided at the end of the plate frame 104 corresponding to the fixed bracket 101 and the sliding bracket 102 away from the slide rail connector 103, and simultaneously, a support column 105 is also provided at the end of the plate frame 104 corresponding to the fixed bracket 101 near the slide rail connector 103, as detailed below. Figure 1 As shown in Figure 2, this embodiment preferably adopts the latter, thus avoiding the collapse of the middle connecting area of ​​the collapsible support 10, which would affect the flatness of the steel frame bed and the seedling effect.

[0034] The support column 105 is used to support the frame 104. In this embodiment, to improve the flexibility of use, the support column 105 is preferably a telescopic sleeve structure. This sleeve structure can be used to adjust the height of the fixed bracket 101 and the sliding bracket 102. The specific adjustment height can preferably be between 800-1200mm. In this embodiment, the height of the support column 105 is preferably 1000mm. After shrinking, the height can be adjusted to 400mm, which greatly reduces the height of the support column 105. It can be understood that this sleeve structure is the existing traditional inner and outer sleeve combination structure. This will not be described in detail here. It can also be understood that in this embodiment, if necessary, in order to further reduce the volume, the support column 105 and the frame 104 can be hinged together by a hinge shaft. The support column 105 can be folded and stored through this hinge shaft.

[0035] As a preferred embodiment, the folding bracket includes a fixed bracket 101 and two translation brackets 102. The two translation brackets 102 are respectively disposed at opposite ends of the fixed bracket 101. When the slide rail connector 103 at one end of the fixed bracket 101 is folded into a Z-shape, the distance between its corresponding pulley seat 1031 and fixed seat 1033 is greater than or equal to twice the distance between its corresponding pulley seat 1031 and fixed seat 1033 when the slide rail connector 103 at the other end is folded into a Z-shape. This ensures that the two translation brackets 102 can be folded up simultaneously without interfering with each other.

[0036] In this embodiment, when using it, first select an appropriate number of foldable supports 10 according to the required steel frame bed size and carefully splice and expand them. Specifically, during the splicing and expansion, each foldable support 10 is first unfolded. The unfolding method includes pushing the translation support 102 to move in the opposite direction relative to the fixed support 101 until it reaches its maximum stroke position, and then pushing to make the connecting rod 1032 rotate relative to its rotation axis with the fixed seat 1033 and the pulley seat 1031, thus unfolding it. At this time, the translation support 102 and the fixed support 101 are connected end-to-end and are in a flush state. During the expansion, the... The two adjacent foldable supports 10 are fixed with straps. After the expansion is completed, the corresponding bed surface 20 is fixed to the support with binding wire, etc. At this time, the expansion of the steel frame bed is completed. When it is necessary to fold, first push up the sliding support 102 to fold the slide rail connector 103 in a Z-shape. At this time, the sliding support 102 is suspended above one side of the fixed support 101. Then push the sliding support 102 to move until it is flush with the end of the fixed support 101 to complete the folding. When storing or transporting, the support column 105 can also be retracted to further reduce its space occupation.

[0037] In summary, this steel-framed bed is modularly assembled from multiple foldable supports 10. The foldable supports 10 achieve a stackable design through the cooperation of slide rail connectors 103 and tracks 106. This structure allows for modular assembly as needed and stacking for storage after use, significantly reducing the bed's volume and footprint. Compared to traditional integrated steel-framed beds, this design offers advantages such as smaller footprint, quick opening and closing, and easy assembly. Furthermore, the simple structure, easy assembly and disassembly, good stability, and excellent ventilation and drainage make this seedling bed ideal for large-scale plant seedling cultivation. It addresses existing shortcomings and possesses significant market value and economic benefits.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
