The clamping mechanism includes a handle 8 and elastic top blocks 9 arranged at both ends of the handle. Both ends of the handle 8 abut against the elastic top block 9 Above, the inner part of the elastic top block 9 abuts against the end of the handle 8 , and the outer part of the elastic top block 9 is exposed to the outside of the longitudinal side plate 4 , corresponding to the two sides of the inner wall of the lateral side plate 3 . A limit block 10 is respectively provided on the side, and a gap 11 is formed between the limit block 10 and the corresponding baffle plate 5 , and the outer end of the elastic top block 9 abuts in the gap 11 .

In the unfolded state of the box body, both the lateral side panels and the longitudinal side panels are arranged perpendicular to the bottom plate, and the outer walls at both ends of the longitudinal side panels abut on the baffles at the ends of the two sets of lateral side panels, Through the limit of the protrusion and the bayonet and the limit of the clamping mechanism; in the folded state of the box body, the longitudinal side plate is attached to the bottom plate, and the lateral side plate is attached to the two sets of lateral sides board.

In this embodiment, the box body is made of plastic, the handle is a U-shaped structure, the two ends of the handle are provided with extension plates, and the ends of the extension plates abut the inner end surface of the elastic top block, so the handle is also made of plastic. , will have a certain elasticity, in which, in the normal use state, that is, in the folded state of the box, the bottoms of the lateral side panels and the longitudinal side panels are attached to the top surface of the bottom plate, and the bottom surfaces of the lateral side panels and the longitudinal side panels are attached to the bottom surface. It is arranged parallel to the top surface of the bottom plate. In the folded state, the outer sides of the lateral side panels and the longitudinal side panels (that is, the bottom surface in the use state) are set perpendicular to the bottom plate. The bottom of the box is attached to the top surface of the bottom plate, so that it cannot continue to be turned outwards to ensure the quality of use. At the same time, the horizontal and vertical side plates will be limited by the protrusions and bayonet, so that the four sides of the box will be limited. All can be connected to each other and limit each other to ensure quality. Wherein, both the lateral side plate and the middle part of the longitudinal side plate are provided with a grab groove, which is convenient for lifting the box body, so that it is convenient to transport the product after the box body is loaded.

The transportation and storage in the state can effectively reduce the cost. When using, first unfold the lateral side panels on both sides so that the lateral side panels are perpendicular to the bottom panel, and then turn the longitudinal side panels outwards so that the longitudinal side panels are perpendicular to the bottom panel. The outer sides of the two sides of the plate will abut on the baffles at the ends of the lateral side plates, and the baffles will be used to block the longitudinal side plates to prevent the longitudinal side plates from overturning. Inside the mouth, a connection relationship is formed between the longitudinal side plate and the transverse side plate, which can ensure the stability of the longitudinal side plate and the transverse side plate after they are turned over, and ensure the firmness of the box. At the same time, during the outward turning of the longitudinal side plates, the elastic top blocks on both sides first touch the limit blocks on the corresponding lateral side plates. Since the longitudinal side plates are subjected to eversion force, the elastic top blocks will be squeezed. Make the elastic top block against the end of the handle, squeeze and deform, so that the elastic deformation shrinks to the inside of the longitudinal side plate, and then after the elastic top block passes the limit block, it is stuck into the gap, and the elastic top block returns to its original state, so that the The longitudinal side plate and the lateral side plate are limited by the elastic top block and the gap, so that the protrusion of the longitudinal side plate can be prevented from detaching from the bayonet, forming a limit, and further ensuring the firmness of the box. When the box body does not need to be loaded with products after use, the box body needs to be folded, so that the operator pulls the handle up to elastically deform the handle, and the end of the handle is separated from the inner end face of the elastic top block, Release the limit of the elastic top block by the handle, and then the operator pushes the longitudinal side plate inward. Since the limit of the elastic top block by the handle disappears, the elastic top block elastically contracts to the inside of the longitudinal side plate, so that all The elastic top block can be separated from the limit of the limit block, and the longitudinal side plate can be folded and attached to the top surface of the bottom plate. Then turn the two lateral side panels inwards, so that the lateral side panels are attached to the longitudinal side panels to complete the folding of the box, which can greatly reduce the space occupation, facilitate the storage of the box itself, and also facilitate the folding of the box. When empty, the space occupation is reduced, and the remaining space can be used to transport other products that do not need to be loaded in the box, which effectively improves the utilization rate of transportation and reduces transportation costs.

2 to 7 , both ends of the handle 8 are respectively provided with first inclined guide surfaces 12 , the first inclined guide surfaces 12 are inclined downward from the outside to the inside, and the first inclined guide surfaces 12 are inclined downward. The top is arranged in the middle of the end surface of the handle 8, the bottom of the first inclined guide surface 12 is arranged on the bottom surface of the handle 8; the inner end of the elastic top block 9 is provided with a second inclined guide surface 13, so The second inclined guide surface 13 is arranged in parallel with the first inclined guide surface 12, the bottom of the second inclined guide surface 13 is arranged in the middle of the inner end of the elastic top block 9, and the second inclined guide surface 13 The top is disposed on the top surface of the elastic top block 9, and the first inclined guide surface and the second inclined guide surface are disposed in the same plane.

In this embodiment, during the opening process of the longitudinal side plate, when the elastic top block first touches the limit block, the elastic top block will first touch the third inclined guide surface, because the longitudinal side plate is turned outwards , subjected to an outward pulling force, so that during the process of turning the longitudinal side plate outward, the elastic top block is gradually inclined and deformed, so that it touches the third inclined guide surface and moves upward. When the elastic positioning completely passes the limit block, the elastic The top block is restored, so that the bottom of the elastic top block is flush with the bottom of the limit block, the elastic top block completely falls into the gap, the limit block is used to restrict the longitudinal side plate from turning inward, and the baffle plate is used to restrict the longitudinal side plate outward Flip to complete the limit.

When the longitudinal side panels need to be folded, pull the handle upward, and the end of the handle, that is, the end of the extension plate, move up a certain distance, so that the first inclined guide surface moves upward, and the elastic top block recovers and contracts inwardly, so that the first inclined guide surface is retracted inward. The second inclined guide surface is attached to the first inclined guide surface, and then the operator pushes the longitudinal side plate to turn inward with a little force, so as to squeeze the elastic top block, so that the elastic top block is contracted inward by the thrust of the limit plate until the The elastic top block is separated from the limit plate. Among them, in the process of opening the longitudinal side panels, the elastic positioning will first touch the third inclined guide surface, and at the same time, due to the existence of the third inclined guide surface, the outer side of the elastic top block will be driven to rise and the inner side will fall. The lowering of the inner side of the top block will cause the second inclined guide surface to descend and contact the first inclined guide surface, which facilitates the deformation of the elastic top block and facilitates the elastic top block to enter the gap through the limit block. When the elastic top block completely enters the gap, the elastic top block lacks the upward thrust of the third inclined guide surface, and the elastic top block returns to its original shape, so that the second inclined guide surface is separated from the first inclined guide surface, so that the end of the handle is against the The inner end of the elastic top block, so that even if the longitudinal side plate is pushed inward by force, the elastic top block cannot be deformed, because it is resisted by the end of the handle, and the handle must be lifted up to make the end of the handle free from the elastic top block. At the end, the elastic top block can be separated from the limit block.

The rod is in a compressed state), the middle part of the lower link is not in contact with the lower limit block (the lower link is in a relaxed state), when the end of the handle is separated from the inner end face of the elastic top block, the elastic top block is in contact with the third inclined guide surface. When (during the unfolding of the box), the elastic top block and the elastic recovery mechanism rotate, the lower link will abut on the top surface of the lower limit block, and the lower link will be squeezed by the lower limit block. When the elastic top block completely leaves the limit After the plate, the deformation of the lower link is restored, and the elastic top block is pushed back to its original state, so that the inner end of the elastic top block will contact the end of the handle to form a limit. Among them, when the handle is pulled up and the end of the handle is separated from the elastic top block, since the elastic top block is no longer limited by the handle, the upper link returns to its original state, and the upper link will push the elastic top block through the upper limit block.
