Description

Technical Field

[0001] The present invention relates to the technical field of container engineering, in particular to a foldable container. Background Art

[0002] A container is a group of tools that can be loaded with packaged or unpackaged goods for transportation and is easy to load, unload and transport using mechanical equipment.

[0003] At present, the market for container ships and car roll-on / roll-off ships is booming. Due to the different heights of different types of cars, the height of the container also limits the height size, resulting in huge waste of space and insufficient space utilization when transporting cars by container ships. Therefore, container ships are rarely used to transport cars.

[0004] At the same time, since the current train load height is 4.8 meters, the railway track surface is 1.1 meters from the vehicle floor, and the effective utilization space is 3.7 meters, placing two layers of existing standard height containers will exceed the specified height. Placing a single layer of containers will easily waste space, resulting in the existing height containers being unable to be used in conjunction with container ships and trains, making it impossible for container ships and trains to transport goods such as cars and obtain the maximum profit space. In addition, the existing standard containers cannot be folded, and are inconvenient to transport after production, and take up a large space for storage. Therefore, it is necessary to provide a foldable container to solve the above problems. Summary of the Invention

[0039] Among them, both ends of the inner side of the side box plate 103 are fixed with a clamping edge for fixing the installation frame 104, and fixing holes are opened at the corresponding positions on both sides of the clamping edge and the installation frame 104. A box door 5 is provided inside the installation frame 104. By providing the clamping edge, when the container body 1 is unfolded, it is ensured that the installation frame 104 is pushed to rotate 90° with the axis of the hinge 3 as the axis and then stop in a vertical state, and then the fixing screws are installed through the fixing holes to achieve effective fixation between the clamping edge and the installation frame 104. By providing the box door 5, it is convenient to enter and exit the goods.

[0040] Among them, a locking assembly 6 is provided on the front of the box door 5, and the locking assembly 6 includes a fixed tube 601, a locking rod 603 and a connecting block 604. The lower end of the fixed tube 601 is fixedly connected to the box door 5, and the lower end of the locking rod 603 is inserted into the fixed tube 601. An L-shaped slot 602 is provided at the upper end of the front of the fixed tube 601. The connecting block 604 is fixedly provided at the lower end of the outer surface of the locking rod 603 and is located in the L-shaped slot 602. A handle 606 is fixedly provided at one end of the connecting block 604 away from the locking rod 603. By holding the handle 606 and controlling the up and down movement of the handle 606, the locking rod 603 can be driven to move up and down synchronously.

[0041] Among them, a positioning column 607 is fixedly provided at the upper end of the L-shaped groove 602, a positioning through-hole 605 that cooperates with the positioning column 607 is provided on the connecting block 604, and a locking hole that cooperates with the locking rod 603 is provided on the lower surface end of the box top plate 102. By holding the handle 606, the handle 606 and the locking rod 603 are pushed up synchronously. When the bottom surface height of the connecting block 604 is higher than the height of the positioning column 607, the handle 606 is pushed to the right to release the handle 606. At this time, the positioning column 607 passes through the positioning through-hole 605 to prevent the locking rod 603 from rotating, and the upper end of the locking rod 603 is inserted into the lock hole to achieve effective locking of the box door 5.

[0042] Among them, the internal support assembly 9 includes four slides 901, two No. 1 brackets 902 and two No. 2 brackets 903. Two slides 901 are slidably arranged inside the No. 1 strip groove 7 and the No. 2 strip groove 701. The two No. 1 brackets 902 are respectively fixedly arranged at the middle end of the upper surface of the two slides 901 in the No. 1 strip groove 7, and the two No. 2 brackets 903 are respectively fixedly arranged at the middle end of the upper surface of the two slides 901 in the No. 2 strip groove 701. The No. 1 strip groove 7 and the No. 2 strip groove 701 are provided to facilitate the installation of the slide 901 and realize the adjustable position of the slide 901.

[0043] Among them, the outer upper ends of bracket No. 1 902 and bracket No. 2 903 are rotatably connected to the inner support rod 904 through a rotating shaft, and a positioning pin 905 is provided at the lower end of the inner support rod 904. The upper ends of bracket No. 1 902 and bracket No. 2 903 are provided with pin holes that cooperate with the positioning pin 905. By providing the positioning pin 905 and the pin hole, the angular position of the inner support rod 904 can be fixed, and then the inner support rod 904 can effectively support the box door 5 to ensure the overall stability. At the same time, when loading a car, the car wheels can be connected to the inner support rod 904 through ropes to limit the position of the car and ensure the stability of the car during transportation.

[0044] Among them, a positioning rod 906 is provided at the end of the upper surface of the slide plate 901, and positioning holes 8 that cooperate with the positioning rod 906 are provided at the middle end and both ends of the inner bottom surface of the No. 1 strip groove 7 and the No. 2 strip groove 701. By providing the positioning rod 906 and the positioning hole 8, the position of the inner support assembly 9 can be effectively limited. When the foldable container is in a folded state, the slide plate 901 can be limited to the middle of the No. 1 strip groove 7 and the No. 2 strip groove 701 by the positioning rod 906 and the positioning hole 8. At this time, the inner support rod 904 is horizontally placed between the two folded side box plates 103, and the inner support rod 904 connected to the No. 1 bracket 902 is located above the inner support rod 904 connected to the No. 2 bracket 903. When the inner support assembly 9 is unfolded, the inner support assembly 9 is moved to the two ends of the No. 1 strip groove 7 and the No. 2 strip groove 701, and positioned by the positioning rod 906 and the positioning hole 8, which does not affect the loading of the car.

[0045] Among them, the overall height of the container body 1 after unfolding is 1727mm, and the overall width and length of the container body 1 after unfolding are equal to the length and width of the standard container. A twist-lock flange 4 is provided between the two corner pieces 2 of the upper and lower container bodies 1, and the middle thickness of the twist-lock flange 4 is 30mm. Since the overall height of the container body 1 after unfolding is 1727mm, it is suitable for container ship transportation when stacked in 3 layers. When stacked in double layers, the sum of the heights of the two layers of foldable containers is less than 3.7 meters, which can be used for train transportation.

[0046] Working principle: when the foldable container is in a folded state, the slide plate 901 can be restricted to the middle of the No. 1 strip groove 7 and the No. 2 strip groove 701 through the positioning rod 906 and the positioning hole 8. At this time, the inner support rod 904 is placed horizontally between the two folded side box plates 103, and is also located between the box bottom plate 101 and the box top plate 102, and the inner support rod 904 connected to the No. 1 bracket 902 is located above the inner support rod 904 connected to the No. 2 bracket 903.

[0047] When the container body 1 is unfolded, the top plate 102 is pulled upward, and the two side plate 103 parts are gradually unfolded to the vertical state. Further, the mounting frame 104 and the door 5 are pushed to unfold, and the clamping edge is provided to ensure that the mounting frame 104 is pushed to rotate 90 degrees with the axis of the hinge 3 as the axis and stops in the vertical state, and then the fixing screws are installed through the fixing holes to achieve effective fixation between the clamping edge and the mounting frame 104, and then the inner support assembly 9 is moved to the two ends of the No. 1 strip groove 7 and the No. 2 strip groove 701, and positioned by the positioning rod 906 and the positioning hole 8 without affecting the loading of the car. When the inner support rod 904 is rotated to a certain angle, the positioning pin 905 and the pin hole are provided to achieve the angular position of the inner support rod 904 fixed, and then the inner support rod 904 can effectively support the door 5 and ensure the overall stability. At the same time, when the car is loaded, the car wheels can be connected to the inner support rod 904 through ropes to limit the position of the car and ensure the stability of the car during transportation.

[0048] Finally, by holding the handle 606, push the handle 606 and the locking rod 603 to move up synchronously. When the bottom surface height of the connecting block 604 is higher than the height of the positioning column 607, push the handle 606 to the right to release the handle 606. At this time, the positioning column 607 passes through the positioning through-hole 605 to prevent the locking rod 603 from rotating, and the upper end of the locking rod 603 is inserted into the lock hole to achieve effective locking of the box door 5. Since the overall height of the container body 1 is 1727mm after unfolding, it is suitable for transportation by container ships when stacked in three layers. When stacked in two layers, the sum of the heights of the two layers of foldable containers is less than 3.7 meters, which can be used for train transportation. It can be used in conjunction with container ships and trains, and cannot enable container ships and trains to transport goods such as cars and obtain the maximum profit space.
