Description

Technical Field

[0001] The embodiments of the present invention relate to logistics transportation equipment, and in particular to a foldable container. Background Art

[0002] A new type of turnover container, this type of container has a series of specifications from large to small. At the same time, this type of container generally has a base and four independent side walls. When recycling, the side walls can be folded relative to the base to reduce the recycling cost. When in use, the two adjacent side walls can bite each other after standing upright. Usually, a lock is provided on two of the opposite side walls, and a cavity is generally provided on the side wall that is rotated upright to install the lock, so that when the side wall with the lock stands upright and bites with the adjacent side wall, the two side walls that stand upright first are completely fixed; at this time, the lock is buckled, and the four side walls are completed upright and fixed. However, since the lock is installed in the side wall, the strength of the lock is a contradiction with the strength of the side wall. When the lock strength is enhanced, the strength of the side wall will be reduced. According to actual use feedback, the impact resistance of this type of lock structure is weak. During the transportation of the whole vehicle, due to the bumps of the road and the inertia caused by acceleration and deceleration, it is easy to cause adjacent containers to collide and squeeze each other, eventually causing the lock or side wall to break, the side wall bite disengagement, damage to the internal goods, and cause additional losses.

[0003] In addition, the two adjacent side walls of such large containers on the market are mostly connected by staggered "T"-shaped hanging platforms, and then cooperate with the side wall lock located at the top of the container to prevent the side wall that stands upright from rotating inward and escaping from the "T"-shaped bite, thereby realizing the fixed connection of the container side wall after standing upright. For example, patent: CN201110295392 proposes a locking method, which is provided with a cavity device driving handle on the side wall, and the driving handle can be rotated to a certain angle. At the same time, a tunnel connecting the cavity and the edge of the side wall is provided on the side wall. The lock is installed in the tunnel, and the lock is driven to slide back and forth in the tunnel by the rotation of the driving handle, thereby realizing the locking function. Similarly, although the above method realizes the locking function of the side plate, when the container is loaded with liquid, the internal liquid will surge back and forth during transportation, and the impact on the side wall and the lock will be greater, and the lock and the side wall are more likely to break and fail. Moreover, after the assembly is completed, the driving handle and the side plate form a semi-enclosed cavity, which is easy to hide dirt and is not easy to clean. Summary of the invention

[0051] Embodiments of the present invention are described below with reference to the accompanying drawings. A first embodiment of the present application relates to a foldable container, which is a relatively large foldable container, such as an IBC, whose capacity is usually above 300L. Such a foldable container usually has a base and two pairs of opposite side panels. The side panels are hinged to the base so that the side panels can be folded relative to the base. Adjacent side panels can be engaged with each other through an engagement structure. Adjacent side panels can be locked with each other by a locking mechanism at the same time to form a box. In the present application, at least one side panel is arranged to be able to flip toward the inside of the box relative to the base after being unlocked with the adjacent side panel, and can also flip toward the outside of the box relative to the base. Preferably, after the side panel flips and disengages from the adjacent side panel, the side panel can be removed from the base. Preferably, one pair of side panels in the two pairs of opposite side panels can flip toward the inside of the box relative to the base, and can also flip toward the outside of the box relative to the base.

[0052] like Figure 1 As shown, the foldable container has a base 2 and two pairs of oppositely arranged side panels. Each side panel is hinged to the base 2, so that the side panel can be folded relative to the base. The side panel 5 and the side panel 6 are adjacent, and the side panel 5 and the side panel opposite to it are shorter than the side panel 6, so the side panel 5 and the side panel opposite to it are short side panels, and the side panel 6 and the side panel opposite to it are long side panels. A small door 1 is provided on the side panel 6, and the small door 1 can be opened or closed relative to the side panel 6, thereby facilitating the user to obtain items at the bottom of the container. Adjacent side panels can be engaged with each other through an engaging structure. An engaging structure is provided on each of the adjacent side panels, and the two engaging structures engage with each other. The shape of the engaging structure is T-shaped or dovetail-shaped, and the angle between the engaging surface and the vertical direction is preferably not more than 15 degrees. The engaging structures cooperate with each other to limit the relative left and right movement between the side panels. The engaging structure can limit the upward displacement of one side panel relative to another side panel, and the adjacent side panels can be locked with each other through a locking mechanism to form a box body.

[0053] like Figure 1 , Figure 2 , Figure 3 As shown, the locking mechanism includes a driving handle 7 and a locking tongue 8 arranged on a side panel, and a locking hole arranged on an adjacent side panel, and a guide groove 10 for the driving handle 7 to be embedded is provided on the side of the side panel facing away from the container, wherein the driving handle 7 is associated with the locking tongue 8 to drive the locking tongue 8 to enter or exit the locking hole. Figure 1As shown in the figure, the side panel 5 and the two adjacent side panels are locked by two locking mechanisms. The two side panels adjacent to the side panel 5 are provided with lock holes, and two sets of driving handles 7 and locking tongues 8 are provided on the side panel 5 to correspondingly lock the two side panels adjacent to the side panel 5. The side panel can also be locked with the two adjacent side panels in the same manner. In addition, a set of driving handles 7 and locking tongues 8 can also be provided on one side panel, that is, the locking tongue 8 on the side panel 5 is inserted into the lock hole in the side panel 6, and the locking tongue 8 on the side panel 6 is inserted into the lock hole of the side panel, and the four side panels are locked in sequence. It can be understood that the guide rail groove can also start on the side of the side panel facing the container.

[0054] In addition, the thickness of the driving handle 7 can be 2mm-4mm, such as 2.5mm, 3mm or 3.5mm. The driving handle 7 occupies less space on the side plate, thereby making the side plate more integrated and more solid.

[0055] From the above content, it can be known that, through the setting of the guide groove 10, the driving handle 7 can be installed into the guide groove 10 from the outer surface of the side wall, making it more convenient for the driving handle 7 to be associated with the lock tongue 8. Moreover, the guide groove 10 is set on the outer surface of the side wall, which can be easily cleaned, so that the inside of the side wall is kept tidy and clean. At the same time, the integrity of the inside of the side wall is maintained, the side wall structure is integrated, the strength of the container side wall is improved, the impact resistance of the container is enhanced, and the goods inside the container are more comprehensively protected.

[0056] In this embodiment, after the side panel 5 is unlocked from the adjacent side panel, it can be flipped toward the inside of the box relative to the base 2, and can also be flipped toward the outside of the box relative to the base 2. The side panel opposite to the side panel 5 can also be flipped toward the outside of the box or toward the inside of the box. It should be understood that only one side panel can be flipped toward both the inside and the outside of the box relative to the base 2 at the same time. Alternatively, four side panels can be flipped toward both the inside and the outside of the box relative to the base 2 at the same time.

[0057] Further, such as Figure 2 and Figure 3 As shown, the locking mechanism has a plurality of locking tongues 8 installed in the side plate at intervals, and the driving handle 7 is provided with a plurality of driving pins 70 spaced apart from each other, each driving pin 70 cooperates with a corresponding locking tongue 8 to drive the locking tongue 8 to move. Figure 2 and Figure 3 As shown, in this embodiment, there are three drive pins 70, and three lock tongues 8 are also provided, and one drive pin 70 is connected to one lock tongue 8. It can be understood that the lock tongues 8 can be 1, 2, or 4, and similarly, the drive pins 70 are also correspondingly 1, 2, or 4. The linkage of multiple lock tongues 8 is realized, and the structure is easy to install and operate, and can maximize the strength of the side plate and the lock tongue 8 at the same time.

[0058] Specifically, Figure 3 , Figure 4 and Figure 6 As shown, the lock tongue 8 includes: a lock tongue body 81 associated with a driving pin 70 and a telescopic member 82 for pushing the lock tongue body 81 into the lock hole. The telescopic member 82 can be an elastic plastic member, connected to the lock tongue body 81. A plurality of accommodating cavities 50 for sliding of the lock tongue 8 are provided in the side panel, and the accommodating cavities 50 have openings for the lock tongue body 81 to enter and exit. Three long holes 11 connected to the accommodating cavities 50 are provided at the bottom of the guide rail groove 10, and a driving groove 80 is provided on the lock tongue body 81, and the driving groove 80 is connected with the corresponding long holes 11. The driving pin 70 passes through the bottom of the guide rail groove 10 and is placed in the driving groove 80, wherein the shape of the driving groove 80 is arranged so that when the driving handle 7 moves up and down in the guide rail groove 10, the driving pin 70 cooperates with the driving groove 80 and the telescopic member 82 to drive the lock tongue body 81 to perform telescopic movement, and the driving groove 80 can be as follows Figure 3 The upper narrow and lower wide form shown in the figure, and the side wall of the driving groove 80 is an inclined surface. Take the locking mechanism between the side plate 5 and the side plate 6 as an example, as shown in FIG. Figure 5 As shown, when the driving handle 7 is pulled upward, the driving pin 70 moves upward in the long hole 11 and moves in the driving groove 80 at the same time, sliding along the side wall of the driving groove 80, pushing the lock tongue body 81 to move leftward, and the lock tongue body 81 moves in the accommodating cavity 50 to push the telescopic member 82, and the telescopic member 82 is pressed against the side of the accommodating cavity 50 toward the opening, and the lock tongue body 81 enters the accommodating cavity 50 and slides out of the lock hole of the side plate 6, so that the side plates 5 and 6 are separated. Figure 4 As shown, when the driving rod 72 slides downward, the driving pin 70 moves downward in the long hole 11 and moves in the driving groove 80 at the same time, and the telescopic member 82 also pushes the lock tongue body 81, so that the lock tongue body 81 slides to the right and slides out of the opening and inserts into the lock hole of the side plate 6, and the side plate 5 and the side plate 6 are locked together. It can be understood that the number of the long holes 11 is the same as the number of the driving pins 70, and can be multiple. When there is only one driving pin 70, one long hole 11 can also be set accordingly.

[0059] In addition, if Figure 5As shown, the lock tongue body 81 and the driving pin can also cooperate with another structure, the lock tongue body 81 is provided with a driving member 800, the driving pin passes through the bottom of the guide groove 10 and cooperates with the driving member 800, the lock tongue body 81 is provided with a driving member 800, and the shape of the driving member 800 is set so that when the driving handle moves up and down in the guide groove 10, the driving pin cooperates with the driving member 800 and the telescopic member to drive the lock tongue body 81 to telescopic movement. The driving member 800 can be a protruding frustum or a cylinder, and the driving pin is provided with a convex block 70a with an inclined guide surface. When the driving handle 7 is pulled upward, the inclined guide surface of the convex block 70a pushes the driving member 800, so that the driving member 800 drives the lock tongue body 81 to move to the left. When the driving rod 72 slides downward, the projection 70a moves downward in the long hole 11, the driving member 800 moves rightward against the projection 70a, and the telescopic member 82 also pushes the lock tongue body 81, so that the lock tongue body 81 slides rightward and slides out of the opening to be inserted into the lock hole of the side plate 6, and the side plate 5 and the side plate 6 are locked together. It can also be understood that the driving pin can also be a protruding cone or a cylinder, and the driving member on the lock tongue body 81 can be a projection with an inclined guide surface.

[0060] More importantly, Figure 7 and Figure 8 As shown, the driving pin 70 has a hook portion 701 inserted into the driving groove 80 and abutting against the side wall 501 of the accommodating chamber 50. Thus, the driving pin 70 is stuck in the side plate 5, the driving handle 7 is also firmly fixed in the side plate, and the driving pin 70 is prevented from slipping out of the driving groove 80.

[0061] In addition, if Figure 4 , Figure 6 and Figure 8 As shown, the driving handle 7 includes: a handle 71 disposed on the top of the side plate 5, and a driving rod 72 connected to the handle 71, and each driving pin 70 is disposed on the driving rod 72. A mounting groove for the handle 71 to enter or exit is provided on the top of the side plate 5, and the mounting groove is connected to the guide rail groove 10. After the lock tongue body 81 enters the lock hole, the handle 71 is embedded in the mounting groove, so that there is no protrusion on the surface of the side plate and no interference.

[0062] Further, such as Figure 4 , Figure 6 and Figure 8As shown, the driving rod 72 is provided with a positioning protrusion 721 inserted into the guide groove 10, and the positioning protrusion 721 is provided with a placement groove 722, wherein the guide groove 10 is provided with a boss 12 inserted into the placement groove 722. The driving handle 7 also includes: a resilient member 73 arranged in the placement groove 722, and the two ends of the resilient member 73 are respectively abutted against the boss 12 and the lower end of the placement groove 722. The resilient member 73 can be a spring or other elastic material. When the container needs to be unlocked, the operating handle 71 moves upward, and the resilient member 73 is in a compressed state. After the operation is completed, the resilient member 73 returns to the pre-compression state, and the driving handle 7 automatically returns to its position.

[0063] The second embodiment of the present invention relates to a foldable container, wherein the locking mechanism of the foldable container is different from the locking mechanism of the first embodiment. Fig. 9 and Fig.10 As shown, the structure of the driving handle 9 and the lock tongue 4 is different from that in the first embodiment. The lock tongue 4 includes a lock tongue body 41 and a telescopic member 42 that abuts against the lock tongue body 41, and the telescopic member 42 is an elastic member, which can be a spring or an elastic plastic member. The driving handle 9 is provided with a driving pin 92, which is connected to the lock tongue body 41. The driving pin 92 is used to drive the lock tongue body 41 to make a telescopic movement when the driving handle 9 moves horizontally, and is also used to drive the lock tongue body 41 to push the telescopic member 42. A plurality of accommodating cavities 500 for sliding of the lock tongue 4 are provided in the side plate, and the accommodating cavities 500 have an opening for the lock tongue body 41 to enter and exit. A plurality of linkage grooves 101 are provided at the bottom of the guide rail groove 100, and the linkage grooves 101 are connected to the corresponding accommodating cavities 500, and the driving pin 92 is inserted into the lock tongue body 41 in the corresponding linkage groove 101 and connected. In this embodiment, there are three lock tongues 4, three accommodating cavities 500, and three linkage grooves 101, and they are connected one by one. Of course, the number of the locking tongue 4, the accommodating cavity 500 and the linkage groove 101 can be one, two or four.

[0064] Further, such as Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, the bolt body 41 is provided with an installation area 40 for installing a telescopic member 42. One end of the telescopic member 42 abuts against the side of the installation area 40 facing the guide groove 100, and the other end of the telescopic member 42 abuts against the inner wall of the accommodating chamber 500 facing the guide groove 100. When the driving handle 9 is operated to slide to the right, the bolt body 41 will be driven to slide to the right together, so that it can withdraw from the lock hole and enter the accommodating chamber 500, thereby completing the unlocking of the side panels 5 and 6.
