Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of loading appliance, especially a folding basket with stable unfolding structure. BACKGROUND

[0002] The folding basket is an appliance used in the links of article rotation, storage and transportation, which is convenient to disassemble and assemble, can be unfolded or folded at any time, is convenient for storage and transportation, saves storage space after folding, and is widely used. In particular, the folding basket made of high-quality plastic can withstand the weight of fruits and vegetables, effectively reduces the collision and extrusion between fruits and vegetables, reduces the loss of fruits and vegetables, and is widely used in the fruit and vegetable industry. At the same time, the basket body can carry intelligent devices such as labels and chips to realize intelligent and digital management of the supply chain and optimize the fresh supply chain.

[0003] With the progress of science and technology, the connection structure design of the folding basket is more and more diverse. For example, the elastic buckle folding basket disclosed in the announcement No. CN217321154U includes a basket bottom plate and first and second long side plates, first and second short side plates hingedly connected to the basket bottom plate. The elastic buckles provided on the first and second short side plates are used to clamp and limit the edges on both sides of the first and second long side plates to form a rectangular basket. Although this kind of folding basket has a certain stability after unfolding, ensuring the bearing capacity of the weight of fruits and vegetables, it needs to move the elastic buckles to cancel the clamping of the edges on both sides of the first and second long side plates when the folding basket is stored and transported or returned to the warehouse. The first and second long side plates are separated from the first and second short side plates, respectively, and then folded, which is the regular operation of folding basket storage. Since the elastic buckles and the first and second short side plates are integrally injection molded, the elastic buckles need to be moved frequently, which will cause mechanical fatigue of the elastic buckles. Over time, the elasticity of the elastic buckles will gradually weaken, and even break. Moreover, in order to ensure that the first and second long side plates can smoothly leave the elastic buckles after the elastic buckles cancel the limitation of the edges on both sides of the first and second long side plates, the height of the limitation structure of each elastic buckle on the first and second long side plates must be controlled. If the limited height is accidentally impacted by strong external force, the first and second long side plates are easy to separate from the corresponding elastic buckles, affecting the normal use of the folding basket. SUMMARY

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a folding basket with a stable unfolding structure.

[0039] As Figures 1-4 shown, the upper end of each main basket plate 2 is provided with a sliding groove 23, and the first buckle part 21 is connected in the sliding groove 23, and a sliding hole 24 is provided on the groove wall of each sliding groove 23 from the outer side of the main basket plate 2, one side of the first buckle part 21 is provided with a bolted segment 211, the second buckle part 31 of each vice basket plate 3 is a bolt hole structure, and each bolted segment 211 is respectively threaded into the same side second buckle part 31 of the corresponding vice basket plate 3 through the sliding hole 24, through the structural design of the first buckle part 21 matched with the sliding groove 23, in the unfolded state of the utility model, the first buckle part 21 is buckled in the corresponding second buckle part 31 of the vice basket plate 3, and a "bolt" latching limiting structure is formed between the main basket plate 2 and the vice basket plate 3, through this structure, the utility model can be effectively prevented from being disconnected from the vice basket plate 3 when subjected to external force from the direction of the main basket plate 2, each main basket plate 2 will not be randomly separated from the vice basket plate 3 towards the inside of the utility model, and the structural stability of the unfolded state of the utility model is ensured, and the first buckle part 21 is preferably made of plastic with high toughness and impact resistance, so that each part of the first buckle part 21 has a certain "elastic stress" after a small amplitude deformation, and can recover to the original state in the first time, and the structure is not easily damaged.

[0040] Further, as Figure 3 , 4As shown, the two sides of the locking segment 211 of each first buckle part 21 are respectively provided with a limiting arm 212, and the inside of the sliding hole 24 of each main basket plate 2 is respectively provided with a limiting part 241, which is used to prevent each first buckle part 21 from being randomly returned into the sliding groove 23 after being connected with the second buckle part 31; wherein the two limiting parts 241 are respectively protruded towards the middle part of the sliding hole 24, so that the spacing width between the two limiting parts 241 is smaller than the width of the sliding hole 24, and a guide inclined surface 24a is respectively arranged at the two ends of the two limiting parts 241, and each guide inclined surface 24a is respectively arranged from the outside to the inside, and the upper surface of the front end of each limiting arm 212 and the end surface are respectively provided with an arm inclined surface 21a, and the arm inclined surface 21a on the same limiting arm 212 is respectively arranged from the outside to the inside; through the cooperation of the guide inclined surface 24a of each limiting part 241 and the arm inclined surface 21a of the corresponding side limiting arm 212, the smoothness of the reciprocating sliding of each limiting arm 212 between the two limiting parts 241 is ensured.

[0041] Specifically, when the utility model is used, the main basket plate 2 and the auxiliary basket plate 3 are respectively unfolded, the first buckle part 21 in the sliding groove 23 is slid towards the sliding hole 24, the locking segment 211 is fed to the second buckle part 31 of the auxiliary basket plate 3 through the sliding hole 24, when the arm inclined surface 21a of each limiting arm 212 approaches and contacts the guide inclined surface 24a of one end of the corresponding limiting part 241, the arm inclined surface 21a cooperates with the guide inclined surface 24a, so that each limiting arm 212 gradually enters between the two limiting parts 241, at the same time, the two limiting parts 241 respectively apply opposite forces to the same side limiting arm 212, so that each limiting arm 212 is passively deformed and approaches the locking segment 211, after the two limiting arms 212 pass through the two limiting parts 241, the force applied by the two limiting parts 241 to the two limiting arms 212 is eliminated, and the two limiting arms 212 restore to the original state under the action of the elastic stress, the first buckle part 21 is locked in the corresponding second buckle part 31 of the auxiliary basket plate 3 through the locking segment 211, forming a locking structure similar to a "door bolt"; the cooperation of the first buckle part 21 and the second buckle part 31 can effectively prevent the utility model from being easily separated from the auxiliary basket plate 3 when it is impacted by external force from the direction of the main basket plate 2, ensuring the stability of the connection structure between the main basket plate 2 and the auxiliary basket plate 3 after the utility model is unfolded; at this time, since the spacing width between the two limiting parts 241 is smaller than the width of the sliding hole 24, the two limiting parts 241 have a certain limiting effect on the limiting arms 212, which can effectively prevent the first buckle part 21 from being randomly returned into the sliding groove 23, ensuring the stability of the locking effect between the first buckle part 21 and the second buckle part 31.

[0042] When the utility model needs to be folded, only need to respectively dial the first buckle part 21 of both sides of main basket plate 2 to slide into corresponding sliding groove 23, the wall part inclined surface of the end of each first buckle part 21 limit arm 212 is close to and contacts the guide inclined surface 24a of the other end of corresponding limit part 241, through arm part inclined surface 21a and guide inclined surface 24a cooperation, each limit arm 212 gradually returns between two limit parts 241, at the same time, two limit parts 241 respectively to the same side limit arm 212 exert opposite force, make each limit arm 212 passive deformation, respectively close to the bolted section 211, when the first buckle part 21 is completely withdrawn in sliding groove 23, the force that two limit parts 241 exerts on two limit arms 212 eliminates, two limit arms 212 restores the original state under the action of elastic stress, at this time, the first buckle part 21 cancels the bolted effect on the second buckle part 31 of auxiliary basket plate 3, so that main basket plate 2 and auxiliary basket plate 3 are folded to bottom plate 1.

[0043] Further, as shown in Figure 3 Each first buckle part 21 bolted section 211 is provided with at least one clamping part 213, and the outer opening of each sliding hole 24 of main basket plate 2 is provided with a reset cutout 24b, which is used to provide a guide position for the clamping part 213 to enter the sliding block when the first buckle part 21 is withdrawn in the sliding groove 23. Each sliding hole 24 is also provided with a limiting hole 24c, which is used to limit the stroke of the first buckle part 21 when it is withdrawn in the sliding groove 23. When the utility model is not unfolded, the clamping part 213 is located in the limiting hole 24c, and the clamping part 213 is inclined in the opposite direction of the setting end of the bolted section 211, so that when the utility model needs to limit the unfolded main basket plate 2 and auxiliary basket plate 3, the clamping part 213 can smoothly leave the limiting hole 24c.

[0044] When the utility model needs to be used, unfold the main basket plate 2 and auxiliary basket plate 3 respectively, dial the first buckle part 21 in the sliding groove 23 to slide in the direction of the sliding hole 24, the bolted section 211 feeds into the second buckle part 31 of auxiliary basket plate 3 through the sliding hole 24, the clamping part 213 of the bolted section 211 moves from one end to the other end of the limiting hole 24c, and continues to be affected by the action force, is forced to feed in the direction of the sliding hole 24, and gradually enters the sliding hole 24. During the process of entering the sliding hole 24, because the height of the inner side of the sliding hole 24 is lower than the protruding height of the clamping part 213, the height limitation of the sliding hole 24 makes the hole wall of the sliding hole 24 exert force on the clamping part 213, forcing the clamping part 213 to deform downward. After the bolted section 211 enters the second buckle part 31 of auxiliary basket plate 3, the clamping part 213 is out of the height limitation of the sliding hole 24, the action force is cancelled, and the clamping part 213 restores to the original state under the action of elastic stress. At this time, the clamping part 213 cooperates with the hole wall of the sliding hole 24 to limit the withdrawal of the first buckle part 21 in the sliding groove 23.

[0045] When it is needed to fold the utility model, only need to respectively move the first buckling part 21 on both sides of the main basket plate 2 to slide into the corresponding sliding groove 23, at this time, the clamping part 213 gradually approaches and contacts the reset notch 24b, and when the first buckling part 21 continues to retreat in the sliding groove 23, the hole wall of the sliding hole 24 exerts force on the clamping part 213, forces the clamping part 213 to deform downward, and gradually enters the sliding hole 24, in the process of entering the sliding hole 24, the height limitation of the sliding hole 24 makes the hole wall of the sliding hole 24 exert force on the clamping part 213, forces the clamping part 213 to deform downward, after the clamping part 213 enters the limiting hole 24c, the clamping part 213 is no longer subjected to the force of the hole wall of the sliding hole 24, and under the action of elastic stress, the clamping part 213 restores to the original state, the convex part in the limiting hole 24c, at the same time, the first buckling part 21 also releases the bolted connection with the second buckling part 31 of the auxiliary basket plate 3, each main basket plate 2 and auxiliary basket plate 3 is folded on the bottom plate 1, which saves the occupied space of the utility model, so as to facilitate the daily storage of the utility model.
