Description

Technical Field

[0001] This invention relates to the field of container technology, and in particular to a connection structure for a modular container and its integrated connection method. Background Technology

[0002] Containers are a special type of transportation tool, increasingly widely used in cargo handling and the construction of temporary spaces. Container design helps enhance the mobility of transportation and shorten the delivery time of goods. Modern uses of containers have expanded beyond transportation, from transporting goods to serving as temporary housing, temporary hospitals, temporary warehouses, temporary repair shops, chapels, and more.

[0003] Currently, in my country's domestic container transport, besides using some international standard containers, small containers are also widely used in some regions and departments. Because the dimensions of these small containers are incompatible with the large international standard containers (such as 20-foot containers) and their loading equipment commonly used in multimodal transport, they must be converted into international standard containers through loading, unloading, and less-than-container-load (LCL) operations before multimodal transport can proceed. Regarding the general specifications for modular containers, modular containers consist of multiple containers connected by couplings to meet the external dimensions of a container and fulfill the requirements for transport and loading / unloading operations. Three or four individual containers, reconnected with couplings, can meet the requirements for container transport and loading / unloading operations. A container composed of three individual containers is called a triplet; a container composed of four individual containers is called a quadruplet. When disassembling a container, the removed couplings are stored in a storage box on top of the container.

[0004] Existing connection methods are complex to operate, and the connectors need to be placed in storage boxes, making them prone to loss. This invention aims to design an integrated combination and fixing method for use in the loading, unloading, transportation, handling, and stacking processes of modular containers. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a connection structure for modular containers and its integrated connection method, in order to solve the problems of existing container assembly requiring the use of connectors, resulting in complex connection operations, low efficiency, and poor connection stability.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] A connecting structure for a modular container includes: a slider and a first positioning block;

[0008] The slider and the first positioning block are respectively disposed on both sides of a single box; the slider is slidably mounted on the box, and when the slider slides relative to the box, it can approach or separate from the first positioning block on the adjacent box;

[0009] The first positioning block can limit the displacement of the slider.

[0010] Furthermore, the slider is provided with a slot; the first positioning block can pass through the slot.

[0011] Furthermore, the first positioning block is rotatably mounted on the housing, and the length of the first positioning block is greater than the width of the slot and the width of the first positioning block is less than the width of the slot.

[0012] Alternatively, a hinged locking structure can be attached to the first positioning block.

[0013] Specifically, the locking structure is connected to the first positioning block by a hinge or by a ball joint.

[0014] Alternatively, a push rod structure can be slidably mounted on the first positioning block; the push rod structure can be engaged in a locking hole on the slider.

[0015] Furthermore, a second positioning block is fixedly installed on the housing, and the second positioning block is located in the middle cavity of the slider.

[0016] Furthermore, the push rod structure includes: a push rod and a push rod lock head;

[0017] The first positioning block is provided with a push rod groove, and the push rod is disposed in the push rod groove and can slide relative to it; a first push rod slot is provided on the side of the push rod groove; the push rod lock head can be locked into the first push rod slot, and the push rod lock head can restrict the displacement of the push rod.

[0018] Furthermore, the push rod is cylindrical, the push rod groove is an arc-shaped groove, and the push rod is fixedly connected to the push rod lock head.

[0019] Furthermore, a second push rod slot is provided on the side of the push rod slide groove; the first push rod slot and the second push rod slot are offset along the extension direction of the push rod slide groove.

[0020] Furthermore, the sliding direction of the push rod structure is perpendicular to the sliding direction of the slider.

[0021] A modular container includes at least two containers, and adjacent containers are connected by the connecting structure.

[0022] An integrated connection method for modular containers, comprising the steps described above, using the connection structure to connect the modular containers:

[0023] Step S1: Push the slider to slide towards the adjacent box;

[0024] Step S2: The first positioning block on the adjacent box slides into the middle cavity of the slider;

[0025] Step S3: The displacement of the slider is restricted by the first positioning block, and the two adjacent boxes are connected into one.

[0026] The technical solution of this invention can achieve at least one of the following effects:

[0027] This invention, through its user-friendly structure, enables the rapid assembly and disassembly of containers, while reducing operation time and improving handover, transfer, and transportation efficiency.

[0028] The present invention relates to a modular container connection structure that, through its integrated design with the container, reduces the use of storage boxes and prevents the loss of parts.

[0029] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0054] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0055] Example 1

[0056] A specific embodiment of the present invention discloses a connection structure for a modular container, comprising: a slider 2 and a first positioning block 3; the slider 2 and the first positioning block 3 are respectively disposed on both sides of a single container body 1; specifically, the slider 2 is slidably mounted on the container body, and when the slider 2 slides relative to the container body 1, it can approach or separate from the first positioning block 3 on the adjacent container body 1; the first positioning block 3 can restrict the displacement of the slider 2; the slider 2 can connect with the first positioning block 3 on the adjacent container body 1. Figure 1 As shown, the first positioning block 3 is located on the left side of the box 1, and the slider 2 is located on the right side of the box 1. The connection between the two adjacent boxes 1 is achieved through the cooperation of the slider 2 on the two adjacent boxes 1 and the first positioning block 3.

[0057] Specifically, such as Figure 1 As shown, slider 2 and first positioning block 3 are respectively located on the left and right sides of housing 1. Figure 12 As shown, when two adjacent boxes 1 are connected, the slider 2 on the right side of the first box 1 slides to the right, causing the first positioning block 3 on the second box 1 to slide into the middle cavity of the slider 2. The first positioning block 3 then limits the slider 2, thus achieving the connection between the two boxes 1.

[0058] Furthermore, such as Figure 1 As shown, a first groove 101 and a second groove 102 are provided on both sides of the housing 1. The slider 2 is slidably installed in the first groove 101, and the first positioning block 3 is provided in the second groove 102.

[0059] Specifically, the first groove 101 is connected to the right side of the housing 1, and the second groove 102 is connected to the left side of the housing 1. In practice, the slider 2 on the left side of the housing 1 can slide from the first groove 101 on the left side of the housing 1 into the second groove 102 on the right side of the housing 1.

[0060] Furthermore, such as Figure 1 As shown, a second positioning block 4 is fixedly installed on the housing 1, and the second positioning block 4 is located in the middle cavity of the slider 2. Specifically, the second positioning block 4 is disposed in the first groove 101 and is fixedly connected to the housing 1. The second positioning block 4 can limit the displacement stroke of the slider 2, that is, when the slider 2 slides to the maximum stroke, it will be blocked by the second positioning block 4 and cannot continue to move.

[0061] Furthermore, such as Figure 1 As shown, slider 2 and second positioning block 4 will not protrude from the first groove 101, and first positioning block 3 will not protrude from the second groove 102. The entire connection structure is embedded to avoid protruding parts affecting the operation of the loading equipment.

[0062] Furthermore, connecting structures are provided on both the front and rear sides of the housing 1.

[0063] In one specific embodiment of the present invention, such as Figure 2 As shown, two sets of connection structures can be set on the upper and lower sides of the box 1. The two sets of connection structures can be used to repeatedly connect the two boxes 1, thereby ensuring a reliable connection between multiple boxes 1.

[0064] Furthermore, the slider 2 is provided with a slot 203; the first positioning block 3 can pass through the slot 203.

[0065] Specifically, slider 2 is a horizontally placed U-shaped structure, such as... Figure 3 , Figure 4 As shown.

[0066] In one specific embodiment of the present invention, the slider 2 includes: upper and lower slider beams 201, a stop beam 202, and a T-shaped protrusion 204. For example... Figure 3 , Figure 4 As shown, the two ends of the stop beam 202 are connected to the upper and lower slider beams 201 respectively, forming a U-shaped structure; the ends of the slider beams 201 protrude inward to form a groove 203, and the width of the groove 203 is smaller than the width of the middle cavity of the U-shape of the slider 2.

[0067] like Figure 5 As shown, T-shaped protrusions 204 are provided below the two slider beams 201. Correspondingly, T-shaped grooves are provided on the housing 1. The T-shaped protrusions 204 are installed in the T-shaped grooves so that the slider 2 can slide relative to the housing 1 and will not fall off the housing 1.

[0068] Preferably, the second groove 102 is also provided with a T-shaped groove that can cooperate with the T-shaped protrusion 204, so that when the slider 2 slides into the second groove 102 of the other box 1, the two boxes 1 are connected, and then the first positioning block 3 is used for positioning to avoid the connection from breaking.

[0069] Furthermore, there are multiple ways in which the first positioning block 3 and the slider 2 can cooperate.

[0070] Preferably, there are at least three connection methods between the first positioning block 3 and the slider 2:

[0071] I) First type:

[0072] The first positioning block 3 is rotatably mounted on the housing 1. The length of the first positioning block 3 is greater than the width of the slot 203 and the width of the first positioning block 3 is less than the width of the slot 203 (not shown).

[0073] During implementation: slide the slider 2 toward the first positioning block 3 on the adjacent box 1. The first positioning block 3 is inserted into the middle cavity of the slider 2 from the slot 203. Rotate the first positioning block 3 to switch it from a horizontal state to a vertical state. Since the length of the first positioning block 3 is greater than the width of the slot 203, the slider 2 is fixed by the first positioning block 3 and the second positioning block 4 (it cannot slide relative to the box 1). The two adjacent boxes 1 are connected into one unit by the slider 2.

[0074] II) The second type:

[0075] like Figure 6 As shown, the first positioning block 3 is hinged with a locking structure 5.

[0076] Specifically, the locking structure 5 and the first positioning block 3 are connected by a hinge or by a ball joint.

[0077] During implementation: slide slider 2 toward the first positioning block 3 on the adjacent box 1. The first positioning block 3 is inserted into the middle cavity of slider 2 from the slot 203. Rotate the locking structure 5 to switch it from the horizontal state to the vertical state. The second positioning block 4 locks one end of slider 2, and the locking structure 5 locks the other end of slider 2. Slider 2 is fixed by the locking structure 5 and the second positioning block 4 (cannot slide relative to box 1). The two adjacent boxes 1 are connected as one unit through slider 2.

[0078] Furthermore, such as Figure 13 As shown, a locking rod structure is provided on the locking structure 5, and correspondingly, a locking hole 304 is provided on the side of the first positioning block 3. The locking rod structure is a telescopic structure.

[0079] When the locking structure 5 is perpendicular to the first positioning block 3, the locking structure 5 can restrict the displacement of the slider 2. At this time, the locking rod structure is aligned with the locking hole 304, and the locking rod structure can be inserted into the locking hole 304 to connect the locking structure 5 with the first positioning block 3 and prevent the locking structure 5 from rotating.

[0080] Specifically, the locking rod structure includes a fixed locking rod 501 and a sliding locking rod 502. The fixed locking rod 501 is perpendicular to the side of the latch structure 5 and is fixedly connected to the latch structure 5; the sliding locking rod 502 is sleeved with the fixed locking rod 501 and can slide relative to it. When the sliding locking rod 502 slides relative to the fixed locking rod 501, the length of the locking rod structure can be extended or shortened.

[0081] Furthermore, such as Figure 13As shown, one end of the sliding locking rod 502 is slidably connected to the fixed locking rod 501, and the other end is a U-shaped portion. The end of the U-shaped portion of the sliding locking rod 502 is provided with two symmetrical engaging portions 503. By squeezing the U-shaped portion, the distance between the two engaging portions 503 can be reduced, thereby allowing the end of the sliding locking rod 502 to engage in the locking hole 304.

[0082] During implementation:

[0083] Rotate the locking structure 5 so that it is perpendicular to the first positioning block 3 and the locking rod structure is aligned with the locking hole 304; press the two engaging parts 503 of the U-shaped part to reduce the width of the end of the sliding locking rod 502; further, pull the sliding locking rod 502 to extend the locking rod structure, thereby allowing the engaging parts 503 to extend into the locking hole 304; release the end of the sliding locking rod 502 of the U-shaped part and restore it under its own metal elasticity, and the engaging parts 503 are locked with the locking hole 304, realizing a reliable connection between the locking structure 5 and the first positioning block 3.

[0084] III) The third type:

[0085] like Figure 7 As shown, a push rod structure 6 is slidably mounted on the first positioning block 3, and the push rod structure 6 can be engaged in the locking hole on the slider 2. The slider 2 and the first positioning block 3 are connected by the push rod structure 6. Specifically, the inner sides of the upper and lower slider beams 201 of the slider 2 are provided with locking holes. Preferably, the locking holes are located at the position of the upper and lower slider beams 201 at the slot 203. After the first positioning block 3 slides into the middle cavity of the slider 2, pushing the push rod structure 6 outward can engage the push rod structure 6 in the locking hole, connecting the slider 2 on one side of the box 1 with the first positioning block 3 on the adjacent box 1 as a whole, thereby connecting the two adjacent boxes 1 as a whole.

[0086] Furthermore, the push rod structure 6 includes: a push rod 601 and a push rod lock head 602;

[0087] The first positioning block 3 is provided with a push rod groove 301, and the push rod 601 is disposed in the push rod groove 301 and can slide relative to it; a first push rod slot 302 is provided on the side of the push rod groove 301; the push rod locking head 602 can be locked into the first push rod slot 302, and the push rod locking head 602 can restrict the displacement of the push rod 601. Further, a second push rod slot 303 is also provided on the side of the push rod groove 301; the first push rod slot 302 and the second push rod slot 303 are offset along the extension direction of the push rod groove 301.

[0088] Preferably, the first push rod slot 302 and the second push rod slot 303 are located on the same side of the push rod slide groove 301 and are spaced apart.

[0089] like Figure 8 As shown, when the first positioning block 3 is not connected to the slider 2, the push rod structure 6 is placed in the push rod groove 301, and the push rod lock head 602 is placed in the second push rod slot 303, so that the push rod structure 6 will not slide in the push rod groove 301.

[0090] like Figure 9 As shown, after the first positioning block 3 is connected to the slider 2, the push rod 601 is inserted into the lock hole on the slider 2, and the push rod lock head 602 is engaged in the first push rod slot 302, preventing the push rod 601 from sliding along the push rod groove 301, thus ensuring a reliable connection between the first positioning block 3 and the slider 2.

[0091] Furthermore, such as Figure 10 , Figure 11 As shown, the push rod 601 is cylindrical, and a push rod lock head 602 is provided on its top. The push rod groove 301 is an arc-shaped groove, and the push rod 601 is fixedly connected to the push rod lock head 602.

[0092] In one specific embodiment of the present invention, the push rod groove 301 is an arc-shaped groove, and the arc shape corresponding to the arc surface of the push rod groove 301 is a superior arc (i.e. an arc surface with a central angle greater than 180°).

[0093] The shape design of the push rod groove 301 allows the push rod structure 6 to rotate within it, and the push rod 601 to slide within it without falling out. The engagement of the push rod locking head 602 with the first push rod slot 302 or the second push rod slot 303 restricts the displacement of the push rod 601 within the push rod groove 301. After the push rod locking head 602 is unscrewed from the first push rod slot 302 or the second push rod slot 303, the push rod structure 6 can slide freely within the push rod groove 301.

[0094] Furthermore, the sliding direction of the push rod structure 6 is perpendicular to the sliding direction of the slider 2.

[0095] During implementation:

[0096] First, rotate the push rod structure 6 to unscrew the push rod lock head 602 from the second push rod slot 303, so that the push rod structure 6 can slide along the push rod slide groove 301.

[0097] Next, the push rod structure 6 is partially pushed out of the push rod groove 301, and the portion of the push rod structure 6 extending out of the push rod groove 301 is inserted into the locking hole of the slider 2. The first positioning block 3 and the slider 2 are connected through the push rod structure 6, as follows. Figure 7 As shown.

[0098] Finally, rotating the push rod structure 6 causes the push rod locking head 602 to engage in the first push rod slot 302, locking the push rod structure 6 so that it cannot slide relative to the push rod slide groove 301, thus preventing the push rod structure 6 from sliding out of the slider 2.

[0099] It is worth noting that the cooperation or connection between the slider 2 and the first positioning block 3 of the present invention is carried out between two boxes 1, that is, the slider 2 on one box 1 cooperates or connects with the first positioning block 3 on the other box 1, thereby realizing the connection between two adjacent boxes 1.

[0100] Furthermore, in order to prevent the push rod lock head 602 from accidentally rotating out of the first push rod slot 302 or the second push rod slot 303 and affecting the connection effect, a self-locking structure 7 is provided above the first push rod slot 302 and / or the second push rod slot 303.

[0101] like Figure 14 As shown, the push rod lock head 602 is provided with a locking groove 603. When the push rod lock head 602 is rotated 90° and inserted into the first push rod slot 302 (or the second push rod slot 303), the locking groove 603 is located above the first push rod slot 302 and parallel to the first push rod slot 302.

[0102] Furthermore, such as Figure 14 , Figure 15 As shown, the self-locking structure 7 includes a self-locking slide 701 and a self-locking rod 702. The self-locking slide 701 is rotatably mounted on the first positioning block 3, with one end rotatably connected to the first positioning block 3 and the other end provided with a self-locking groove 703. The self-locking rod 702 is a telescopic rod, and it can be engaged in the self-locking groove 703. Specifically, the self-locking rod 702 is installed in a blind hole on the first positioning block 3, and a spring is provided below the self-locking rod 702, with one end connected to the self-locking rod 702 and the other end connected to the bottom of the blind hole.

[0103] When the self-locking rod 702 is engaged in the self-locking groove 703, the self-locking structure 7 is in a self-locking state. When the self-locking rod 702 is pressed down to make it lower than the self-locking slider 701, the self-locking structure 7 is in an unlocked state.

[0104] During implementation: Pressing the self-locking lever 702 allows the self-locking slide 701 to rotate freely, and the self-locking structure 7 is in the unlocked state. Rotating the self-locking slide 701 ensures that it does not obstruct the first push rod slot 302 (or the second push rod slot 303), and rotating the push rod structure 6 causes the push rod lock head 602 to engage with the first push rod slot 302 (or the second push rod slot 303). Further, rotating the self-locking slide 701 causes it to engage with the locking groove 603 on the push rod lock head 602. Releasing the self-locking lever 702 switches the self-locking structure 7 from the unlocked state to the locked state. The self-locking lever 702 re-engages with the self-locking groove 703, and the self-locking slide 701 cannot rotate. The rotation of the push rod structure 6 is restricted by the cooperation between the self-locking slide 701 and the locking groove 603, thus achieving a reliable connection between the push rod structure 6 and the slider 2.

[0105] The connection structure of the present invention uses a "multiple locking" method to achieve the connection between the first positioning block 3 and the slider 2, ultimately ensuring a stable and reliable connection between adjacent housings 1.

[0106] Example 2

[0107] In one specific embodiment of the present invention, a modular container is provided, comprising at least two container bodies 1, wherein two adjacent container bodies 1 are connected by the connection structure described in Embodiment 1.

[0108] Specifically, a container consisting of three separate containers connected together is called a triple container; a container consisting of four separate containers connected together is called a quadruple container.

[0109] Example 3

[0110] A specific embodiment of the present invention provides an integrated connection method for modular containers, which uses the connection structure in Embodiment 1 to connect the modular containers in Embodiment 2; the method includes the following steps:

[0111] Step S1: Push slider 2 to slide towards the adjacent box 1;

[0112] Step S2: The first positioning block 3 on the adjacent box 1 slides into the middle cavity of the slider 2;

[0113] Step S3: By restricting the displacement of the slider 2 through the first positioning block 3, the two adjacent boxes 1 are connected as one unit.

[0114] In one specific embodiment of the present invention, in step S1:

[0115] like Figure 12As shown, two boxes 1 are placed side by side. The slider 2 on the first box 1 is slid outward from the first groove 101, so that the slider 2 on the first box 1 slides into the second groove 102 on the second box 1.

[0116] Preferably, when the slider 2 slides into the second groove 102 of the other housing 1, the T-shaped protrusion 204 on the slider 2 also slides into the T-shaped groove on the second groove 102.

[0117] In one specific embodiment of the present invention, in step S2:

[0118] like Figure 12 As shown, when slider 2 slides to its maximum stroke, the left end of slider 2 is blocked by the second positioning block 4 on its own housing 1, and the left end of slider 2 is limited by the second positioning block 4. Meanwhile, the right end of slider 2 passes over the first positioning block 3 on the second housing 1, and the first positioning block 3 on the second housing 1 slides into the middle cavity of slider 2.

[0119] Preferably, the first positioning block 3 is located in the slot 203 of the slider 2.

[0120] In one specific embodiment of the present invention, step S3 is shown as follows:

[0121] The first box 1 is connected to the second box 1 via a slider 2. Specifically, the slider 2 cooperates with the first positioning block 3.

[0122] Furthermore, depending on the different structural components of the first positioning block 3, the cooperation method between the first positioning block 3 and the slider 2 is as follows:

[0123] 1) When the first positioning block 3 is rotated and installed on the housing 1:

[0124] Rotate the first positioning block 3 to make its length direction vertical, and then limit the right end of the slider 2 through the first positioning block 3.

[0125] Specifically, the first positioning block 3 can prevent the slider 2 from sliding to the left, and the second positioning block 4 can prevent the slider 2 from sliding to the right, thereby connecting two adjacent boxes 1.

[0126] 2) When the locking structure 5 is hinged to the first positioning block 3:

[0127] The first positioning block 3 is inserted into the slot 203 of the slider 2. The rotating locking structure 5 is made perpendicular to the first positioning block 3, and the sliding of the slider 2 is restricted by the locking structure 5.

[0128] Specifically, the locking structure 5 can prevent the slider 2 from sliding to the left, and the second positioning block 4 can prevent the slider 2 from sliding to the right, thus connecting the two adjacent boxes 1.

[0129] 3) When the push rod structure 6 is slidably installed on the first positioning block 3:

[0130] First, rotate the push rod structure 6 to unscrew the push rod lock head 602 from the second push rod slot 303, so that the push rod structure 6 can slide along the push rod slide groove 301.

[0131] Next, the push rod structure 6 is partially pushed out of the push rod groove 301, and the portion of the push rod structure 6 extending out of the push rod groove 301 is inserted into the locking hole of the slider 2. The first positioning block 3 and the slider 2 are connected through the push rod structure 6, as follows. Figure 7 As shown. The two housings 1 are connected by a push rod structure consisting of six parts: the first positioning block 3 and the slider 2.

[0132] Finally, rotating the push rod structure 6 causes the push rod locking head 602 to engage in the first push rod slot 302, locking the push rod structure 6 so that it cannot slide relative to the push rod slide groove 301, thus preventing the push rod structure 6 from sliding out of the slider 2.

[0133] This invention designs a first positioning block 3 and a slider 2 at the left and right ends of the container, respectively. When assembling the two independent container bodies 1, the operator can push the slider 2 to the right by holding the stop beam 202 of the slider 2, sliding it into the second groove 102 of the other container body 1. The left side of the slider 2 is fixed by the second positioning block 4, and the excess part fits against the first positioning block 3. After alignment, the right side of the slider 2 is fixed by the cooperation of the first positioning block 3 and the slider 2, thus completely fixing the slider 2. This allows for the fixed assembly of the two independent container bodies 1. Figure 12 As shown. The method of the present invention can be used to fix three-unit or four-unit containers.

[0134] Compared with existing technologies, the present invention is easy to operate, allows for quick assembly and disassembly of containers, reduces operation time, and improves handover and transportation efficiency. Through its integrated design with the container, it reduces the use of storage boxes to prevent the loss of parts.

[0135] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
