Description

TECHNICAL FIELD

[0001] The utility model relates to logistics transport container technical field, specifically provide a kind of folding basket's stacking structure and folding basket with lid. BACKGROUND

[0002] Turnover basket is generally applied to industrial assembly line turnover, warehouse storage or is used for agricultural loading fruits, vegetables etc. In order to save space, foldable turnover basket (abbreviation folding basket) has gradually popularized. Folding basket is usually stacked after being unfolded and loaded, to improve space utilization. When folding basket is loaded, folding basket with cover plate on side plate will be through rotating cover plate, let cover plate cover the upper surface of folding basket, prevent goods in folding basket from falling out during handling. However, when stacking, the bottom surface of upper folding basket is placed on the surface formed by the cover plate of lower folding basket, since the cover plate of lower folding basket is always under the pressure of the bottom of upper base, when the weight of goods is too heavy, the cover plate is also prone to damage under long-term stress, and local deformation is also prone to occur to crush goods. SUMMARY

[0003] In order to solve the above problems, the utility model provides a kind of folding basket's stacking structure and folding basket with lid, avoid sliding displacement between stacked folding baskets, and also ensure that the cover plate will not be deformed and damaged.

[0004] The technical scheme of the utility model is as follows:

[0005] A kind of folding basket's stacking structure with lid, including side plate and base, the side plate is provided with protrusion, the protrusion is vertically protruding on the upper surface of the side plate when the side plate is vertically unfolded.

[0006] Among them, protrusion is arranged on side plate, when folding basket is stacked, the protrusion on lower folding basket supports the bottom of upper folding basket. Protrusion vertically supports upper folding basket, the gravity of upper folding basket is all received by protrusion and transmitted to base through vertical side plate, in the case that bearing effect is better, also let the bottom surface of upper folding basket base not contact with the cover plate of lower folding basket, effectively avoid deformation and damage of the cover plate of folding basket under stress.

[0007] Preferably, the bottom of the base is provided with a groove, the protrusion can be inserted into the groove, the height of the protrusion is greater than or equal to the depth of the groove.

[0008] In this scheme, the height of the protrusion is greater than the depth of the groove, to ensure that the protrusion can always support the base of the folding basket, and the protrusion inserted into the groove can also play a limiting role, to avoid sliding between stacked folding baskets and cause the folding basket to fall.

[0009] Preferably, the side plate comprises a pair of high side plates and a pair of low side plates, the high side plates and the low side plates are arranged adjacently, the protrusions comprise main protrusions arranged on the high side plates, the cover plate of the folding basket is arranged on the high side plates in a rotating manner, and the low side plates can support the cover plate of the folding basket when arranged in a vertical unfolded state.

[0010] Since the cover plate of the folding basket serves a covering function, in order to reduce costs, the thickness and strength of the folding basket formed by injection molding are far less than those of the side plate, the base and other structures, and therefore the cover plate of the folding basket is prone to damage and falling off in a long-term use. In order to avoid this situation, preferably, the rotating joint of the cover plate of the folding basket and the high side plate is arranged between the two main protrusions, which effectively prevents other external equipment from being installed on the rotating joint of the cover plate, protects the rotating joint of the cover plate of the folding basket, reduces the risk of damage to the cover plate, and prolongs the service life.

[0011] Preferably, the protrusions further comprise secondary protrusions arranged on the upper surfaces of the low side plates when the low side plates are arranged in a vertical unfolded state, and the cover plate of the folding basket is provided with a slot hole matched with the secondary protrusions.

[0012] In this scheme, when the cover plate of the folding basket covers the upper surface of the folding basket, the cover plate of the folding basket can be inserted by the secondary protrusions, thereby limiting the movement of the folding basket in all directions except the rotating direction, and the cover plate of the folding basket, especially the rotating joint of the cover plate of the folding basket, can be prevented from being damaged due to external factors such as collision.

[0013] Preferably, when the side plate is arranged in a vertical unfolded state, the top surface of the secondary protrusion is at the same level as the top surface of the main protrusion.

[0014] In this scheme, the secondary protrusion plays a limiting role on the cover plate of the folding basket, and at the same time, the secondary protrusion can support the folding basket above together with the main protrusion, so that the entire side plate can transmit the gravity of the folding basket above to the base, and the stress is more uniform.

[0015] In order to improve the strength and supporting capacity of the secondary protrusion, the secondary protrusion is generally arranged vertically, and the cover plate of the folding basket is rotated from one side and is not inserted vertically by the secondary protrusion. Therefore, in order to avoid interference between the secondary protrusion and the cover plate of the folding basket, preferably, the top edge of the secondary protrusion is provided with a chamfer, and the size of the cross section of the upper end of the secondary protrusion is reduced by arranging the chamfer, so that the cover plate of the folding basket which is rotated can be more easily inserted by the secondary protrusion.

[0016] Preferably, the size of the slot hole on the cover plate of the folding basket is greater than the size of the cross section of the secondary protrusion, and when the secondary protrusion is inserted into the slot hole on the cover plate of the folding basket, one chamfer surface of the secondary protrusion is in interference contact with the slot hole.

[0017] In this scheme, through the interference contact of the chamfer surface and the slot hole, the contact pressure of the sub-protrusion and the inner wall of the slot hole is increased, so that when the cover plate of the folding basket is placed on the low side plate, it will not rotate randomly, and when carrying a single folding basket, the problem of the cover plate of the folding basket shaking and making noise due to the shaking of the folding basket can be avoided.

[0018] A folding basket with a cover includes a base, foldable side plates and a cover plate, and a folding basket with a cover stacking structure described above. By arranging the stacking structure, the protrusions on the side plates of the lower folding basket support the folding basket placed above, preventing the cover plate from deforming and being damaged under stress. At the same time, the protrusions on the lower side plates are inserted into the grooves in the base of the upper folding basket, serving as a limiting function to prevent the stacked folding baskets from sliding and falling.

[0019] The utility model discloses the beneficial effects of:

[0020] 1. The utility model discloses a protrusion is arranged on the side plate, and the protrusion vertically supports the folding basket above, and the gravity of the folding basket above is all received by the protrusion and is passed through the vertical side plate and is delivered to the base, and under the condition that the bearing effect is better, the bottom surface of the base of the folding basket above also does not contact the cover plate of the folding basket below, effectively avoiding that the cover plate of the folding basket deforms and is damaged under stress.

[0021] 2. The recess is arranged on the base of the folding basket in the utility model, and the protrusion on the side plate of the lower folding basket can be inserted into the recess in the bottom surface of the base of the upper folding basket, and the protrusion and the recess are limited in position, avoiding the sliding of the stacked folding baskets and the falling of the folding baskets.

[0030] The technical scheme of the present application is clearly and completely explained by the specific implementation manners of the embodiments of the present application in combination with the drawings.

[0031] Embodiment one:

[0032] As shown in Figure 1 and Figure 2 A stack structure of a folding basket with a cover includes a side plate 1 and a base 2, the side plate 1 is provided with a protrusion 3, the protrusion 3 vertically protrudes from the upper surface of the side plate 1 when the side plate 1 is vertically unfolded, and the protrusion 3 on the lower folding basket supports the bottom of the upper folding basket when the folding baskets are stacked. The protrusion 3 is arranged on the side plate 1 and is vertically arranged to support the upper folding basket, and the gravity of the upper folding basket is all received by the protrusion 3 and transmitted to the base 2 through the vertical side plate 1, so that the bottom surface of the base 2 of the upper folding basket is not in contact with the cover 4 of the lower folding basket, and deformation and damage of the cover 4 of the folding basket under stress are effectively avoided.

[0033] Specifically, the base 2 is provided with a groove 21 at the bottom, the groove 21 is generally arranged at the bottom edge of the base 2 and corresponds to the position of the side plate 1, the protrusion 3 can be inserted into the groove 21, and the height of the protrusion 3 is greater than or equal to the depth of the groove 21. In this embodiment, the height of the protrusion 3 is greater than the depth of the groove 21, so that the protrusion 3 can always support the base 2 of the folding basket, and the protrusion 3 inserted into the groove 21 can also play a limiting role, avoiding the sliding between the stacked folding baskets and causing the folding baskets to fall.

[0034] Further, the base 2 can also be provided with a ladder structure at the bottom edge, and only the rectangle formed by the side plate 1 can limit the movement of the stacked folding baskets in the horizontal direction.

[0035] More specifically, as shown in Figure 1 and Figure 4The side panel 1 shown includes a pair of high side panels 11 and a pair of low side panels 12, which are arranged adjacent to each other. The protrusion 3 includes a main protrusion 31 arranged on the high side panel 11. The cover plate 4 of the folding basket is rotatably arranged on the high side panel 11. When the low side panel 12 is arranged vertically, it can support the cover plate 4 of the folding basket and prevent the cover plate 4 from being over-folded and directly contacting the goods in the basket.

[0036] It should be noted that, since the cover plate 4 of the folding basket serves to cover, in order to reduce costs, the thickness and strength of the injection-molded folding basket are generally much lower than those of the side plate 1, base 2, and other structures. Therefore, under long-term use, the cover plate 4 of the folding basket is very prone to damage and detachment. To avoid this situation, the rotating joint at the connection between the cover plate 4 and the high side plate 11 is set between the two main protrusions 31. This effectively prevents other external equipment from installing on the rotating joint of the cover plate 4, thus protecting the rotating joint of the cover plate 4, reducing the risk of damage to the cover plate 4, and extending its service life.

[0037] In this embodiment, different folding baskets can have different protrusion 3 structures and numbers due to the different side plate 1 structures. When the high side plate 11 is connected and fixed to the low side plate 12, right-angle extensions parallel to the low side plate 12 are set at both ends of the high side plate 11. At this time, the main protrusion 31 on the high side plate 11 can be set at the corner of the high side plate 11 to form a bent right-angle protrusion 3 structure. The four corners of the entire folding basket are provided with right-angle bent main protrusions 31. With the protrusion 3 structure of the base 2, the folding baskets can be conveniently and accurately limited and stacked. At the same time, the force is all borne by the high side plate 11, which can also reduce the situation where the high side plate 11 and the low side plate 12 are not firmly connected due to uneven force on the low side plate 12 and the high side plate 11.

[0038] Example 2:

[0039] Based on Embodiment 1, in order to distribute the weight of the main protrusion 31 and make the force on the lower folding basket more even, such as Figures 1 to 4 As shown, the protrusion 3 also includes a secondary protrusion 32 disposed on the upper surface of the lower side plate 12 when the lower side plate 12 is vertically unfolded. The cover plate 4 of the folding basket is provided with a slot 41 adapted to the secondary protrusion 32. When the side plate 1 is vertically unfolded, the top surface of the secondary protrusion 32 is at the same level as the top surface of the main protrusion 31.

[0040] In this embodiment, when the cover plate 4 of the folding basket covers the upper surface of the folding basket, the cover plate 4 of the folding basket can be inserted by the secondary protrusion 32, thereby limiting the movement of the folding basket in all directions except the rotating direction, and avoiding damage to the cover plate 4 of the folding basket, especially the rotating joint of the cover plate 4 of the folding basket, caused by external factors such as collision. The secondary protrusion 32 can limit the cover plate 4 of the folding basket at the same time, and can support the folding basket above at the same time with the primary protrusion 31, so that the entire side plate 1 can transmit the gravity of the folding basket above to the base 2, and the stress is more uniform.

[0041] Further, in order to improve the strength and supporting capacity of the secondary protrusion 32, the secondary protrusion 32 is generally vertically arranged, and the cover plate 4 of the folding basket is rotated from one side, not vertically inserted by the secondary protrusion 32. Therefore, in order to avoid interference between the secondary protrusion 32 and the cover plate 4 of the folding basket, preferably, a chamfer is arranged at the top edge of the secondary protrusion 32, and the size of the cross section of the upper end of the secondary protrusion 32 is reduced by arranging the chamfer, so that the cover plate 4 of the rotating folding basket is more easily inserted by the secondary protrusion 32.

[0042] Further, as shown in Figure 5 the size, i.e. the width and the length, of the slot hole 41 on the cover plate 4 of the folding basket is greater than the size of the cross section of the secondary protrusion 32, and when the secondary protrusion 32 is inserted into the slot hole 41 on the cover plate 4 of the folding basket, one chamfer surface of the secondary protrusion 32 is in interference contact with the slot hole 41. By the interference contact between the chamfer surface and the slot hole 41, the contact pressure between the secondary protrusion 32 and the inner wall of the slot hole 41 is increased, and the contact pressure between the cover plate 4 and the slot hole 41 gradually increases during the turning process of the cover plate 4, so that greater friction is generated, and the cover plate 4 of the folding basket will not be randomly rotated when placed on the low side plate 12. When carrying a single folding basket, the problem that the cover plate 4 of the folding basket shakes and makes noise can be avoided.

[0043] More specifically, the lower end of the chamfer surface of the secondary protrusion 32 in interference contact with the slot hole 41 is provided with a small groove 21, i.e. only the chamfer surface is in interference contact with the slot hole 41, and when the chamfer portion of the secondary protrusion 32 completely passes through the slot hole 41, the secondary protrusion 32 can be gap-fitted with the slot wall of the slot hole 41 through the small groove 21, and self-locking is formed by the elastic force of the secondary protrusion 32 itself.

[0044] Embodiment three:

[0045] On the basis of the above-mentioned embodiments, as shown in Figure 1The folding basket with a cover shown comprises a base 2, foldable side plates 1, a cover plate 4 and the stacking structure of the folding basket with a cover described above. The folding basket is provided with the stacking structure, when the folding baskets are stacked, the protrusions 3 on the side plates 1 of the lower folding basket support the folding basket placed above, avoiding the cover plate 4 from being deformed and damaged under force, at the same time, the protrusions 3 on the side plates 1 of the lower folding basket are inserted into the grooves 21 of the base 2 of the folding basket placed above, playing a limiting role, avoiding the sliding between the stacked folding baskets and the falling of the folding baskets.
