[0051] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0052] like Figure 1 As shown, a stacking rack includes a base frame 1, side railings A2 and B3, as... Figure 2 As shown, the base frame 1 includes a base mesh 1a and supports 1b fixed to the four corners of the base mesh 1a. The mesh density of the base mesh 1a is selected according to the material being loaded. The supports 1b are made of channel steel, have 90° angles, and cover the four corners of the base mesh 1a. Typically, the base mesh 1a and supports 1b are made of steel, and the supports 1b are connected to the four corners of the base mesh 1a by welding. It is understood that, to improve interchangeability, the supports 1b can also be fixed to the four corners of the base mesh 1a by bolts.

[0053] like Figure 1 , Figure 4 and Figure 5 As shown, the side fence A2 is hinged to two opposite sides of the base mesh 1a. The side fence A2 can be rotated inward by 90°. The width of the base mesh 1a is greater than twice the height of the side fence A2, so that after the two side fences A2 are rotated inward by 90°, one side fence A2 will not overlap the other. Two fixing pins 2a are provided on the outer wall of the side fence A2. The fixing pins 2a can be welded to the outer wall of the side fence A2, or they can be locked to the outer wall of the side fence A2 by threads. Figure 1 , Figure 6 and Figure 7As shown, the side fence B3 is arranged on the other two opposite edges of the bottom net la and connected with the legs lb on both sides of the side fence B3. The side fence B3 can also be turned inward by 90°. The length of the bottom net la is greater than twice the height of the side fence B3, so that when the two side fences B3 are turned inward by 90°, one side fence B3 does not overlap the other side fence B3. The top of the side fence B3 is provided with a V-shaped block 3a along the length direction. Preferably, the top angle of the V-shaped block 3a is 90°, as shown in Figure 2 As shown, a V-shaped groove 1c is arranged between the two legs lb on the lower side of the side fence B3, as shown in Figure 6 and Figure 7 As shown, a press-lock eccentric buckle 3c is hingedly installed on the end wall of the side fence B3, as shown in Figure 6 As shown, at least two V-shaped plates 3d are arranged on the bottom of the outer wall of the side fence B3. When the side fence B3 is turned inward by 90° (folded), the V-shaped plate 3d is equivalent to the V-shaped block 3a. When stacking, the V-shaped groove 1c is pressed on the V-shaped plate 3d;

[0054] When unfolded and stacked, as shown in Figure 10 The V-shaped groove 1c can be pressed on the top of the corresponding side V-shaped block 3a, and the press-lock eccentric buckle 3c can be clamped on the corresponding side fixed pin 2a. The press-lock eccentric buckle 3c is clamped on the fixed pin 2a, which adopts a T-shaped structure. When the press-lock eccentric buckle 3c is clamped on the fixed pin 2a, the cooperation between the fixed pin 2a and the press-lock eccentric buckle 3c can limit the inward turning of the side fence A2, so that the bottom net la, the two side fences A2 and the two side fences B3 form a loading space with an open top;

[0055] When folded and stacked, as shown in Figure 11 , Figure 12 and Figure 16 As shown, the side fence A2 and the side fence B3 can be turned inward by 90°. At this time, the V-shaped groove 1c can be pressed on the top of the corresponding side V-shaped plate 3d. It should be noted that after the two side fences B3 are turned inward by 90°, the corresponding V-shaped plate 3d is just below the V-shaped groove 1c of the upper layer of shelves. Since there is no internal cargo when folded and stacked, only the V-shaped plate 3d needs to bear the weight of the upper shelf, so the number of V-shaped plates 3d is preferably 2-4, which can bear the weight of the upper shelf.

[0056] In this invention, both side fence A2 and side fence B3 have a certain thickness. The lower edges of both side fence A2 and side fence B3 are flush with the top surface of the bottom mesh 1a. When side fence A2 is rotated inwards by 90°, if side fence B3 were to rotate inwards directly, side fence A2 would block side fence B3, preventing it from rotating inwards. Therefore, this invention designs side fence B3 to be able to slide up and down, with a sliding distance at least equal to the thickness of side fence B3. Specifically, as shown... Figure 3 As shown, the upper part of the support leg 1b is provided with a 7-shaped groove 1b1, and the lower part of the two end walls of the side railing B3 is respectively fixed with positioning pins 3b, which are slidably connected to the 7-shaped grooves 1b1 on the corresponding side. When flipping the side railing B3, the side railing B3 is slid upwards a certain distance (at least the thickness of the side railing A2), and then the side railing B3 is flipped inwards.

[0057] Preferred, such as Figure 3 As shown, the upper groove width of the 7-type groove 1b1 is greater than the diameter of the positioning pin 3b, allowing the positioning pin 3b to slide easily within the 7-type groove 1b1. When the positioning pin 3b is raised to the top of the 7-type groove 1b1, it is pulled a short distance towards the center, causing the weight of the bottom of the side railing B3 to press against the horizontal groove of the 7-type groove 1b1. When the side railing B3 is unfolded, the support leg 1b, being made of channel steel, also restricts the side railing B3 from flipping outward. The lower part of the 7-type groove 1b1 is provided with a tapered section 1b11 whose groove width gradually decreases. The bottom opening of the tapered section 1b11 is equal to the diameter of the positioning pin 3b. When the positioning pin 3b slides down to the bottom, the tapered section 1b11 and the positioning pin 3b fit tightly together, ensuring that the bottom of the side railing B3 does not shift horizontally after unfolding.

[0058] Preferably, the tail of the eccentric locking buckle 3c is hinged to the end wall of the side fence B3, such as... Figure 9 As shown, the front end of the eccentric locking buckle 3c has a hook-shaped structure. When the eccentric locking buckle 3c flips downward, the bottom of the hook-shaped structure can just be engaged with the fixing pin 2a. When the eccentric locking buckle 3c flips upward, the opening of the hook-shaped structure gradually moves away from the fixing pin 2a. The distance between the hook-shaped structure and the fixing pin 2a is L. When the eccentric locking buckle 3c flips from bottom to top, the value of L gradually increases. Conversely, when the eccentric locking buckle 3c flips downward, the opening of the hook-shaped structure gradually approaches the fixing pin 2a, and the value of L gradually decreases, that is, it becomes tighter and tighter.

[0059] For the best options, please continue to refer to them. Figure 9The top middle position of the pressure locking eccentric buckle 3c is further provided with a pressing head 3c2, and the inner side bottom edge of the V-shaped groove 1c of the upper layer is pressed in the top of the pressing head 3c2 when the stack is unfolded. As long as the upper layer shelf is stacked on the lower layer shelf, the V-shaped groove 1c of the upper layer will always be pressed on the top of the pressing head 3c2, the pressure locking eccentric buckle 3c cannot be separated from the fixed pin 2a, and the heavier the goods, the tighter the pressure locking eccentric buckle 3c and the fixed pin 2a, so that the stability of the shelf is higher.

[0060] Preferably, please continue to refer to Figure 9 The front end side wall of the pressure locking eccentric buckle 3c is further provided with a push rod 3c1, which can be pushed upwards after the upper layer shelf is removed, so that the pressure locking eccentric buckle 3c is turned upwards, the hook-shaped structure is separated from the fixed pin 2a, and the side rail A2 and the side rail B3 can be turned inwards in sequence.

[0061] Preferably, please continue to refer to Figure 10 When the stack is unfolded, there is a gap between the inner side surface of the V-shaped groove 1c of the upper layer and the V-shaped block 3a, and the value s of the gap is 0.1-1mm. The outer side surface of the V-shaped block 3a is first subjected to the pressure of the V-shaped groove 1c, and as the goods are stacked, the pressure becomes larger and larger, so that the side rail B3 is pressed inwards, and the contact surface connection between the inner side surface of the side rail B3 and the end surface of the side rail A2 is more closely connected.

[0062] Preferably, as shown in Figure 5 The two end walls of the side rail A2 are respectively provided with protrusions 2b, and as shown in Figure 7 The two end walls of the side rail B3 are respectively provided with recesses 3e, and when the stack is unfolded and the hook-shaped structure is clamped on the fixed pin 2a, the protrusions 2b are clamped in the recesses 3e. After the protrusions 2b and the recesses 3e are matched, they have the effect of mutual restriction, which can prevent the side rail A2 and the side rail B3 from swinging inwards and outwards when unfolded. It can be understood that the shapes of the protrusions 2b and the recesses 3e are not limited, as long as the protrusions 2b and the recesses 3e can be matched. In the embodiment, the protrusions 2b are long strip structures, and the recesses 3e are long groove structures matched with the protrusions 2b.

[0063] In another embodiment of the utility model, as shown in Figure 14 And Figure 15 The bottom surface of the bottom net 1a is flush with the bottom of the supporting leg 1b, that is, a "legless" shelf. The "legless" shelf is more space-saving when folded and stacked, as shown in Figure 16 .

[0064] Preferably, as shown in Figure 1 , Figure 8 And Figure 10As shown, further comprising a heat dissipation assembly 4, the heat dissipation assembly 4 comprises a heat dissipation pipe 4a and a mounting seat 4b, the mounting seat 4b is fixedly installed at the center position of the bottom net 1a, the lower end of the heat dissipation pipe 4a is inserted into the mounting seat 4b, and a plurality of heat dissipation holes 4a1 communicating with the inside of the heat dissipation pipe 4a are formed on the side wall of the heat dissipation pipe 4a. The heat dissipation pipe 4a is a detachable structure, when folded, the heat dissipation pipe 4a can be detached and stored separately, which does not affect the stacking. When the goods loaded on the shelf are fruits and vegetables, the heat dissipation pipe 4a can timely discharge the heat inside the shelf.

[0065] In addition, Figure 13 Another folding and stacking mode of the "footed" shelf, Figure 17 Another folding and stacking mode of the "footless" shelf, on the basis of the conventional folding and stacking, the adjacent shelves are stacked by rotating 90°, so that the V-shaped groove 1c of the upper layer is staggered with the V-shaped plate 3d, thereby making the folding and stacking more compact.

[0066] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
