Description

CONNECTING ASSEMBLY, CONTAINER, MODULAR CONTAINER, AND HOOK STRUCTURETECHNICAL FIELD

[0001] The present application relates to the field of connection technology, and more specifically to a connecting assembly, container, modular container, and hook structure.

[0002] BACKGROUND

[0003] During disassembly and assembly operations, users often need to bring multiple toolboxes to the site according to the task requirements in order to select the most suitable hand tools. For the convenience of transportation, it is necessary to stack and connect multiple toolboxes together. In existing technologies, the connecting mechanism between adjacent toolboxes is relatively complex, with cumbersome operations that are time-consuming and labor-intensive, resulting in low disassembly efficiency.

[0004] However, given the wide variety and different sizes of hand tools, the corresponding toolboxes also are in the form of diverse shapes and sizes. This directly leads to difficulties for users in effectively combining and fixing multiple toolboxes when carrying them, greatly increasing the inconvenience of carrying. Moreover, when organizing and storing these toolboxes of various shapes, it is difficult to arrange them neatly, resulting in the waste of space resources.

[0101] DETAILED DESCRIPTION OF THE EMBODIMENTS

[0102] The following will provide a clear and complete description of the technical solution in the embodiments of the present application, combined with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of this application.

[0103] As shown in FIGS. 1 to 12, the embodiments of the present application provide a connecting assembly for connecting a first module 100a and a second module 200a. The connecting assembly includes a sliding engaging structure 2a. The first module 100a and the second module 200a are arranged adjacent to each other. For example, the first module 100a and the second module 200a can be stacked vertically or placed side by side horizontally. The connecting assembly can be applied to containers such as toolboxes, tool cases, storage boxes, storage baskets, drawer boxes, rolling cases, and tool bags. The connecting assembly can also be applied to rigid platforms such as pallets, external panels, adapter plates, worktables, and drawing boards. The connecting assembly is mainly used for interlocking between two modules, wherein the first module 100a can be a container, and the second module 200a can also be a container, so that the connecting assembly allows for interlocking between two containers; or, the first module 100a / second module 200a can be a container, while the second module 200a / first module 100a can be a rigid platform, so that the connecting assembly allows for interlocking between a container and a rigid platform; or, the first module 100a can be a rigid platform, and the second module 200a can also be a rigid platform, so that the connecting assembly allows for interlocking between two rigid platforms.

[0104] For illustrative purposes, the embodiments are described with the first module 100a and the second module 200a being stacked vertically.

[0105] The sliding engaging structure 2a includes at least one blocking part and at least one holding part. In the embodiments of the present application, the blocking parts and the holding parts have the same quantity, with both being set to two, three, or four, and each blocking part corresponds to a holding part. The blocking parts are provided on the first module 100a, and the holding parts are provided on the second module 200a. When the blocking parts and the holding parts are engaged with each other, the blocking parts are engaged between the holding parts and the second module 200a, and the holding parts are engaged between the blocking parts and the first module 100a, thereby restricting the first module 100a and the second module 200a from being separated in a direction away from each other. At this point, the first module 100a and the second module 200a are slidably connected, with the sliding direction being perpendicular to or forming an angle with the stacking direction of the first module 100a and the second module 200a.

[0106] There are multiple blocking parts arranged in the extension direction of the sliding engaging structure 2a, and there are multiple holding parts arranged in the extension direction of the sliding engaging structure 2a. For example, there are two blocking parts and two holding parts. In this way, the connection between the first module 100a and the second module 200a is more stable and reliable in the extension direction of the sliding engaging structure 2a through the cooperation of multiple sets of the blocking parts and the holding parts. Herein, the spacing between adjacent blocking parts is greater than the length of the holding part, and the spacing between adjacent holding parts is greater than the length of the blocking part. When the first module 100a and the second module 200a are connected, it is not necessary for the first module 100a and the second module 200a to be completely misaligned, and as long as the holding parts and the blocking parts are misaligned, the holding parts can extend into the position between the blocking parts and the first module 100a, and the blocking parts can extend into the position between the holding parts and the second module 200a. This design makes the operation convenient, time-saving, and labor-saving.

[0107] In a preferred embodiment, the sliding engaging structure 2a includes a first sliding engaging structure 201a and a second sliding engaging structure 202a. The first sliding engaging structure 201a includes a first blocking part 21a and a first holding part 23a. The first blocking part 21a is provided on the first module 100a, and the first holding part 23a is provided on the second module 200a. The first blocking part 21a and the first holding part 23a can be engaged with each other, thereby restricting the first module 100a and the second module 200a from being separated in a direction away from each other. The second sliding engaging structure 202a includes a second blocking part 22a and a second holding part 24a. The second blocking part 22a is provided on the first module 100a, and the second holding part 24a is provided on the second module 200a. The second blocking part 22a and the second holding part 24a can be engaged with each other, thereby restricting the first module 100a and the second module 200a from being separated in a direction away from each other. Herein, the first sliding engaging structure 201a and the second sliding engaging structure 202a are spaced apart and arranged in parallel, that is, the relative sliding direction of the first holding part 23a and the first blocking part 21a is parallel to the relative sliding direction of the second blocking part 22a and the second holding part 24a, and they are not on the same straight line. In this way, through the design of the first sliding engaging structure 201a and the second sliding engaging structure 202a, the sliding connection between the first module 100a and the second module 200a is ensured to be stable and reliable, thereby improving the stability of disassembly and assembly.

[0108] In one embodiment of the present application, the first blocking part 21a and the second blocking part 22a both protrude from the first module 100a and extend in directions facing each other. The first holding part 23a and the second holding part 24a both protrude from the second module 200a and extend in directions away from each other. For example, the extension directions of the first blocking part 21a and the second blocking part 22a are towards each other, and the extension directions of the first holding part 23a and the second holding part 24a are away from each other. When the first blocking part 21a is engaged with the first holding part 23a, and the second blocking part 22a is engaged with the second holding part 24a, the first sliding engaging structure 201a and the second sliding engaging structure 202a are each interlocked. At this time, under the dual effect of the first sliding engaging structure 201a and the second sliding engaging structure 202a, the first module 100a and the second module 200a cannot be separated in a direction away from each other, nor can they move in the arrangement direction of the first sliding engaging structure 201a and the second sliding engaging structure 202a (this arrangement direction is the arrangement direction of the first blocking part and the second blocking part, and also is the arrangement direction of the first holding part and the second holding part, and is perpendicular to the extension direction of the first sliding engaging structure 201a and the second sliding engaging structure 202a). As a result, the first module 100a and the second module 200a can only slide in the extension direction of the first sliding engaging structure 201a and the second sliding engaging structure 202a. In another embodiment of the present application, the first blocking part 21a and the second blocking part 22a both protrude from the first module 100a and extend in directions away from each other, and the first holding part 23a and the second holding part 24a both protrude from the second module 200a and extend in directions facing each other.

[0109] As shown in FIGS. 10 and 11, in one embodiment of the present application, at least one of the first sliding engaging structure 201a and the second sliding engaging structure 202a is provided on one side of the first module 100a and the second module 200a. When the first module 100a and the second module 200a are connected, it is necessary to keep one side of the first module 100a and one side of the second module 200a aligned. At this time, one of the first sliding engaging structure 201a and the second sliding engaging structure 202a is provided at the aligned side position. In this way, by providing the first sliding engaging structure 201a or the second sliding engaging structure 202a at the side position, the internal space of the first module 100a and the second module 200a can be avoided from being affected.

[0110] Specifically, the first sliding engaging structure 201a and the second sliding engaging structure 202a are respectively provided on the opposite sides of the first module 100a or the second module 200a. Here, taking the arrangement direction of the first sliding engaging structure 201a and the second sliding engaging structure 202a as the reference direction (that is, the left-to-right direction in FIG. 11), the dimension of the first module and the second module in this reference direction is defined as the width of the first module and the second module, that is, the extension direction of the first sliding engaging structure 201a and the second sliding engaging structure 202a is defined as the length direction of the first module and the second module. When the width of the first module 100a is greater than the width of the second module 200a, the first sliding engaging structure 201a and the second sliding engaging structure 202a are respectively provided at the two side positions of the second module 200a, and correspondingly, one of the first sliding engaging structure 201a and the second sliding engaging structure 202a is provided at one side position of the first module 100a, and the other is provided at the middle position of the first module 100a; when the width of the first module 100a is less than the width of the second module 200a, the first sliding engaging structure 201a and the second sliding engaging structure 202a are respectively provided at the two side positions of the first module 100a, and correspondingly, one of the first sliding engaging structure 201a and the second sliding engaging structure 202a is provided at one side position of the second module 200a, and the other is provided at the middle position of the second module 200a; when the width of the first module 100a is the same as the width of the second module 200a, the first sliding engaging structure 201a and the second sliding engaging structure 202a are respectively provided at the two side positions of the first module 100a, and also are respectively provided at the two side positions of the second module 200a. In this way, the connection of modules with different widths can be realized.

[0111] In some preferred embodiments, the first blocking part 21a has a first flat surface 211a on the side away from the first module 100a, the first holding part 23a has a second flat surface 231a on the side away from the second module 200a, the second blocking part 22a has a third flat surface 221a on the side away from the first module 100a, and the second holding part 24a has a fourth flat surface 241a on the side away from the second module 200a. When the first module 100a and the second module 200a are connected, the first flat surface 211a and the third flat surface 221a both abut against the second module 200a, and the second flat surface 231a and the fourth flat surface 241a both abut against the first module 100a. To ensure smooth sliding when the holding parts and the blocking parts are engaged, the second flat surface 231a and the fourth flat surface 241a do not contact the first module 100a.

[0112] Further, the first blocking part 21a has a first inclined surface 212a on the side facing the second blocking part 22a, wherein the first inclined surface 212a is inclined relative to the first flat surface 211a. The second blocking part 22a has a third inclined surface 222a on the side facing the first blocking part 21a, wherein the third inclined surface 222a is inclined relative to the third flat surface 221a. The first holding part 23a has a second inclined surface 232a on the side away from the second holding part 24a, wherein the second inclined surface 232a is inclined relative to the second flat surface 231a. The second holding part 24a has a fourth inclined surface 242a on the side away from the first holding part 23a, wherein the fourth inclined surface 242a is inclined relative to the fourth flat surface 241a. When the first module 100a and the second module 200a are slidably connected, the first inclined surface 212a abuts against the second inclined surface 232a, and the third inclined surface 222a abuts against the fourth inclined surface 242a.

[0113] In this way, by providing flat surfaces and inclined surfaces on the blocking parts and the holding parts, the sliding connection between the first module 100a and the second module 200a can be made more secure and stable, thereby enhancing the stability of the installation of the first module 100a and the second module 200a.

[0114] Further, the connecting assembly may also include an interlocking structure. The interlocking structure is provided on adjacent first and second modules 100a and 200a. For example, the interlocking structure is provided on the contact surface where the first module 100a and the second module 200a are in contact, or on the sides of the first module 100a and the second module 200a that are close to each other. The interlocking structure has a locked state and an unlocked state, and the interlocking structure can switch between the locked and unlocked states through its own movement. When the interlocking structure is in the locked state, it restricts the movement of the sliding engaging structure 2a, that is, the blocking parts and the holding parts in the sliding engaging structure 2a are restricted from sliding relative to each other, so that the first module 100a and the second module 200a are locked together. When the interlocking structure is in the unlocked state, the blocking parts and the holding parts can slide relative to each other, allowing the first module 100a and the second module 200a to slide relative to each other, so that the blocking parts and the holding parts can slide to a misaligned position, thereby allowing the first module 100a and the second module 200a to be separated.

[0115] With this arrangement, the sliding engaging structure 2a can realize the sliding connection between the first module 100a and the second module 200a. The interlocking structure can lock the sliding engaging structure 2a to restrict the movement of the sliding engaging structure 2a, thereby preventing the relative sliding of the first module 100a and the second module 200a. The combination of the sliding engaging structure 2a and the interlocking structure can achieve mutual locking of the first module 100a and the second module 200a. This design is simple in structure, facilitates the disassembly and assembly of the first module 100a and the second module 200a, saves time and effort, and is easy to operate.

[0116] In some embodiments, the interlocking structure includes an interlocking latch 1a and a limiting part 25a, wherein the locking direction of the interlocking latch 1a is not the same as the extension direction of the sliding engaging structure 2a, thereby forming an angle (such as a right angle) between the locking direction of the interlocking latch 1a and the extension direction of the sliding engaging structure 2a, such that the interlocking latch 1a will cause interference with the movement of the sliding engaging structure 2a, thereby locking the first module 100a and the second module 200a together through the interlocking latch 1a and the sliding engaging structure 2a.

[0117] The limiting part 25a is provided on the first module 100a, and the limiting part 25a is arranged along the extension direction of the sliding engaging structure 2a together with the blocking parts. The distance between the limiting part 25a and the nearest blocking part is less than the length of the holding part corresponding to this nearest blocking part (the distance between the limiting part 25a and the blocking part can be zero, i.e., the limiting part 25a can be provided on the blocking part). When the holding part is engaged with the blocking part, the holding part abuts against the limiting part 25a, and at this moment, the first module 100a and the second module 200a are aligned to each other. With the design of the limiting part 25a, the holding part is prevented from sliding excessively relative to the blocking part, thereby limiting the first module 100a and the second module 200a in the aligned position. In some embodiments, the limiting part 25a is located between the blocking part and the first module 100a, facilitating the holding part to insert from either side of the blocking part to engage with the blocking part.

[0118] In a preferred embodiment, the interlocking latch 1a includes a locking member 10a and a locking groove 11a. The locking groove 11a is provided on the first module 100a, and the locking member 10a is provided on the second module 200a. For example, when the first module 100a and the second module 200a are connected, the locking member 10a and the locking groove 11a are both located on the side positions of the first module 100a and the second module 200a, facilitating the operation of locking and unlocking. Further, the locking member 10a can move relative to the second module 200a (this movement can be set as rotation or sliding, meaning the locking member 10a is rotatably or slidably connected to the second module 200a), allowing the locking member 10a to extend into or retract from the locking groove 11a. When the interlocking latch 1a is in the locked state, the locking member 10a extends into the locking groove 11a. When the interlocking latch 1a is in the unlocked state, the locking member 10a retracts out of the locking groove 11a. Thus, by extending and retracting the locking member 10a into and out of the locking groove 11a, the interlocking latch 1a can switch between the locked state and the unlocked state.

[0119] Further, the interlocking latch 1a also includes a first elastic member 14a. The first elastic member 14a is connected between the locking member 10a and the second module 200a, and the first elastic member 14a can drive the locking member 10a to move relative to the second module 200a, causing the locking member 10a to move and finally interfere with the locking groove 11a (i.e., the locking member 10a extends into the locking groove 11a), thereby automatically maintaining the interlocking latch 1a in the locked state. When the first module 100a is connected to the second module 200a and the interlocking latch 1a is in the locked state, the first elastic member 14a abuts against the locking member 10a, causing the locking member 10a to align with the locking groove 11a. As a result, the locking member 10a is automatically locked in the locking groove 11a under the action of the first elastic member 14a.

[0120] Below is a detailed explanation of the interlocking latch 1a in conjunction with some specific embodiments.

[0121] In the embodiment shown in FIGS. 6 to 9, the second module 200a is stacked on top of the first module 100a. The interlocking latch 1a is designed as a flip latch. The locking member 10a includes an operating piece 12a and a latch tongue 13a. The operating piece 12a is connected to the second module 200a and can flip relative to the second module 200a. Specifically, one side of the second module 200a is provided with a flip slot (not labelled), and one end of the flip slot is open, allowing the open end of the flip slot to communicate with the side of the second module 200a. The first elastic member 14a, which can be a spring, is connected between the operating piece 12a and the second module 200a. Under the action of the first elastic member 14a, the operating piece 12a can automatically flip in the locking direction. Specifically, the first end of the operating piece 12a is rotatably connected to the bottom wall of the flip slot via a pivot, and the first elastic member 14a is disposed between the bottom wall of the flip slot and the middle part of the operating piece 12a, so that the first elastic member 14a can drive the second end of the operating piece 12a to rotate. The latch tongue 13a is provided at the second end of the operating piece 12a, near the open end of the flip slot, and can extend downward into the locking groove 11a.

[0122] The locking groove 11a is provided on the first module 100a with its opening facing the second module 200a. When the first module 100a and the second module 200a are aligned, the locking groove 11a and the latch tongue 13a are also aligned. Under the action of the first elastic member 14a, the operating piece 12a drives the latch tongue 13a to flip downward into the locking groove 11a, putting the interlocking latch 1a in the locked state, thus preventing the sliding engaging structure 2a from moving and, consequently, stopping the relative sliding between the first module 100a and the second module 200a. By manually applying force to lift the operating piece 12a, the latch tongue 13a is pulled out of the locking groove 11a, putting the interlocking latch 1a in the unlocked state, thus allowing the sliding engaging structure 2a to move and, consequently, permitting the relative sliding between the first module 100a and the second module 200a.

[0123] In one embodiment of the present application, as shown in FIG. 12A and 12B, the connecting assembly is used in the hook structure of two containers. At least one blocking part of the sliding engaging structure is provided on the first module 100a, and at least one holding part of the sliding engaging structure is provided inside the second module 200a. Specifically, the blocking parts 21a, 22a of the sliding engaging structure 2a are provided on the bottom of the first module 100a, and the holding parts 23a, 24a of the sliding engaging structure 2a are provided on the inner side wall of the second module 200a. The first module 100a is connected inside the second module 200a through the sliding engaging structure 2a, so that the first module 100a is hooked on the inner side wall of the second module 200a, and the side of the first module 100a near the bottom of the second module 200a is in contact with the bottom of the second module 200a. In a preferred embodiment, the holding part 23a / 24a extends upward from the bottom of the second module 200a, and the limiting part 25a is provided on the first module 100a away from the bottom of the second module 200a. The end of the holding part 23a / 24a of the second module 200a away from the bottom of the second module 200a abuts against the limiting part 25a, such that the side of the first module 100a near the bottom of the second module 200a is not in contact with the bottom of the second module 200a, thus not occupying the bottom space of the second module 200a.

[0124] As shown in FIGS. 10 and 11, the present application provides a modular container, which includes a first module 100a and a second module 200a. The first module 100a and the second module 200a are connected through the connecting assembly described in the aforementioned embodiments. With this arrangement, the structure is simple, facilitating the disassembly and assembly of the first module 100a and the second module 200a, thereby saving time and effort.

[0125] In some preferred embodiments, the first module 100a and the second module 200a have the same size. Both the first module 100a and the second module 200a can be full-size modules, half-size modules, or quarter-size modules. When the first module 100a and the second module 200a are stacked, the shape is symmetrical, which is convenient for storage and transportation.

[0126] In other preferred embodiments, the size of the first module 100a is smaller than that of the second module 200a. For example, the size of the second module 200a can be twice that of the first module 100a, and also, the size of the second module 200a can be three or four times larger than that of the first module 100a, so that the second module 200a is a full-size module while the first module 100a is a half-size or quarter-size module. Moreover, multiple first modules 100a can be simultaneously connected and locked to a single second module 200a through the connecting assembly, forming a stack of multiple first modules 100a and one second module 200a. In this way, the stacking combination of modules of different sizes can be realized.

[0127] Specifically, the arrangement direction of the multiple first modules 100a can be parallel or perpendicular to the extension direction of the sliding engaging structure 2a.

[0128] It can be understood that the description of the size of the second module 200a being twice that of the first module 100a can be defined as: in the arrangement direction of the first sliding engaging structure 201a and the second sliding engaging structure 202a, the dimension of the second module 200a is twice that of the first module 100a; or on the contact surface where the first module 100a and the second module 200a are connected, the edge length dimension of the second module 200a is twice that of the first module 100a.

[0129] In some other embodiments, as shown in FIGS. 13 to 25, the sliding engaging structure 2b is the same as that described in the aforementioned embodiments, including a first sliding engaging structure and a second sliding engaging structure. The first sliding engaging structure includes a first blocking part 21b and a first holding part 23b, while the second sliding engaging structure includes a second blocking part 22b and a second holding part 24b. The details will not be repeated here. The difference lies in the structure of the interlocking latch 1b. The interlocking latch 1b includes a locking member 10b and a mating part 111b. The locking member 10b is provided on the second module 200b and can slide relative to the second module 200b. The mating part 111b is provided on the first module 100b. The locking member 10b and the mating part 111b are designed to interact. By changing the position of the locking member 10b relative to the mating part 111b, the interlocking latch 1b can switch between a locked state and an unlocked state. When the interlocking latch 1b is in the locked state, the locking member 10b interferes with the mating part 111b in a displacement direction of the first module 100b and the second module 200b, thereby restricting the movement of the first module 100b and the second module 200b in the displacement direction. When the interlocking latch 1b is in the unlocked state, the locking member 10b does not interfere with the mating part 111b, allowing the first module 100b and the second module 200b to move in the displacement direction.

[0130] In a preferred embodiment, the interlocking latch 1b includes the locking member 10b and a locking groove 11b. The locking groove 11b is provided on the first module 100b, and the mating part 111b is designed as a side wall of the locking groove 11b. The locking member 10b abuts against the side wall of the locking groove 11b to form interference between the locking member 10b and the mating part 111b. The locking member 10b is provided on the second module 200b. For example, when the first module 100b and the second module 200b are connected, the locking member 10b and the locking groove 11b are both located on the side positions of the first module 100b and the second module 200b, facilitating the operation of locking and unlocking. Further, the locking member 10b can move relative to the second module 200b (this movement is set as sliding, meaning the locking member 10b is slidably connected to the second module 200b), allowing the locking member 10b to extend into and retract from the locking groove 11b. When the interlocking latch 1b is in the locked state, the locking member 10b extends into the locking groove 11b. When the interlocking latch 1b is in the unlocked state, the locking member 10b retracts out of the locking groove 11b. Thus, by extending and retracting the locking member 10b into and out of the locking groove 11b, the interlocking latch 1b can switch between the locked state and the unlocked state.

[0131] Further, the interlocking latch 1b also includes a first elastic member 14b. The first elastic member 14b is connected between the locking member 10b and the second module 200b, and the first elastic member 14b can drive the locking member 10b to move relative to the second module 200b, causing the locking member 10b to move and finally interfere with the locking groove 11b (i.e., the locking member 10b extends into the locking groove 11b), thereby automatically maintaining the interlocking latch 1b in the locked state. When the first module 100b is connected to the second module 200b and the interlocking latch 1b is in the locked state, the first elastic member 14b abuts against the locking member 10b, causing the locking member 10b to align with the locking groove 11b. As a result, the locking member 10b is automatically locked in the locking groove 11b under the action of the first elastic member 14b.

[0132] Further, the connecting assembly includes a retaining structure 3b. The retaining structure 3b includes a first retaining part 31b and a second retaining part 32b. The first retaining part 31b is provided on the interlocking latch 1b and moves with the interlocking latch 1b. For example, the first retaining part 31b is provided on the locking member 10b and moves with the locking member 10b relative to the first module 100b. The second retaining part 32b is provided on the first module 100b, and the first retaining part 31b and the second retaining part 32b are designed to interact. When the interlocking latch 1b moves in the first direction (i.e., the unlocking direction of the interlocking latch 1b) to the unlocked state, the first retaining part 31b abuts against the second retaining part 32b in the second direction (i.e., the locking direction of the interlocking latch 1b), restricting the interlocking latch 1b from moving in the locking direction of the interlocking latch 1b, and keeping the interlocking latch 1b in the unlocked state. Here, when the interlocking latch 1b is kept in the unlocked state, the abutting surfaces of the first retaining part 31b and the second retaining part 32b are set as flat surfaces, which can make the abutting action more reliable and enhance the structural stability of the retaining structure 3b, ensuring that the interlocking latch 1b is safely and stably held in the unlocked state.

[0133] It should be noted that when the first retaining part 31b abuts against the second retaining part 32b in the second direction, the first retaining part 31b cannot pass over the second retaining part 32b without any external force. For example, both the first retaining part 31b and the second retaining part 32b have flat surfaces perpendicular to the unlocking direction of the interlocking latch 1b (i.e., the second direction). The two flat surfaces abut against each other to create a blocking effect. At this time, only by separating the first retaining part 31b from the second retaining part 32b and preventing them from abutting can the retaining action of the retaining structure 3b be rendered ineffective. Alternatively, one or both of the first retaining part 31b and the second retaining part 32b may have inclined or curved surfaces. By using the abutting forms of flat surface and inclined surface, or inclined surface and inclined surface, the blocking effect can be achieved. At this time, as long as the elastic force of the first elastic member 14b is always less than the abutting force between the first retaining part 31b and the second retaining part 32b, the retaining action of the retaining structure 3b will remain effective without any external force. With this arrangement, the interlocking latch 1b is kept in the unlocked state by the retaining structure 3b. That is, without the need of applying a retaining force to the interlocking latch 1b, the interlocking latch 1b can be held in the unlocked state, thereby facilitating the separation of the first module 100b and the second module 200b, enabling quick disassembly, simple operation, and saving time and effort.

[0134] In a preferred embodiment, the retaining structure 3b also includes a second elastic member 33b. The second elastic member 33b is provided between the first retaining part 31b and the interlocking latch 1b. Under the action of the second elastic member 33b, the first retaining part 31b moves in a direction different from the unlocking direction of the interlocking latch 1b. For example, the second elastic member 33b is provided between the locking member 10b and the first retaining part 31b, and the second elastic member 33b can drive the first retaining part 31b to move in a direction perpendicular to the first direction, allowing the first retaining part 31b to abut against the second retaining part 32b in the second direction. When both the interlocking latch 1b and the sliding engaging structure 2b are in the locked state, the first retaining part 31b is located on the side of the second retaining part 32b facing the locking direction of the interlocking latch 1b. When the interlocking latch 1b drives the first retaining part 31b to move in the first direction, the first retaining part 31b can pass over the second retaining part 32b due to the presence of the second elastic member 33b. Subsequently, the first elastic member 14b rebounds to drive the first retaining part 31b to move into abutment with the second retaining part 32b. In this way, the design of the second elastic member 33b can improve the smoothness of the interlocking latch 1b during the unlocking process and maintaining the unlocked state.

[0135] When the interlocking latch 1b drives the first retaining part 31b to move in the first direction, the first retaining part 31b and the second retaining part 32b can cooperate through inclined surfaces. Specifically, one side of the first retaining part 31b is provided with an inclined surface (not labelled). When the inclined surface abuts against the second retaining part 32b, the first retaining part 31b can compress the second elastic member 33b, allowing the first retaining part 31b to pass over the second retaining part 32b.

[0136] As shown in FIG. 18, in a first preferred embodiment, the first retaining part 31b is pivotally connected to the interlocking latch 1b. The second elastic member 33b can drive the first retaining part 31b to rotate relative to the interlocking latch 1b, causing it to protrude from the interlocking latch 1b. Specifically, the locking member 10b is provided with a flip slot (not labelled). The first retaining part 31b is designed in an L-shape, with the first end of the first retaining part 31b pivoted inside the flip slot. The second elastic member 33b, which can be a spring or a torsion spring, is disposed between the second end of the first retaining part 31b and the bottom wall of the flip slot, thereby driving the first retaining part 31b to protrude from the flip slot.

[0137] As shown in FIG. 19, in a second preferred embodiment, the first retaining part 31b is slidably connected to the interlocking latch 1b. The second elastic member 33b can drive the first retaining part 31b to slide relative to the interlocking latch 1b, causing it to protrude from the interlocking latch 1b. Specifically, the locking member 10b is provided with a sliding slot (not labelled). The first retaining part 31b is located inside the sliding slot. The second elastic member 33b, which is a spring, is disposed between the first retaining part 31b and the bottom wall of the sliding slot, thereby driving the first retaining part 31b to protrude from the sliding slot.

[0138] As shown in FIG. 20, in a third preferred embodiment, the first retaining part 31b and the second elastic member 33b are integrally formed with the interlocking latch 1b. The second elastic member 33b drives the first retaining part 31b to protrude from the interlocking latch 1b through its own elastic potential energy. Specifically, the locking member 10b is provided with a receiving cavity (not labelled). The first retaining part 31b is connected to the receiving cavity through the second elastic member 33b. The first retaining part 31b and the second elastic member 33b are integrally formed. The first retaining part 31b protrudes from the receiving cavity through the elasticity of the second elastic member 33b.

[0139] Below is a detailed explanation of the interlocking latch 1b in conjunction with some specific embodiments.

[0140] As shown in FIGS. 13 to 17, the interlocking latch 1b is designed as a horizontally sliding latch. The upper surface of the first module 100b is provided with an installation slot (not labelled), which penetrates the side of the first module 100b. The first side wall of the installation slot protrudes to form the mating part 111b, and the locking groove 11b is formed between the mating part 111b and the bottom wall of the installation slot. The second retaining part 32b protrudes to be formed between the first and second side walls of the installation slot, dividing the installation slot into two parts. The lower portion of the second module 200b is provided with a sliding cavity (not labelled), with openings on the side and bottom of the sliding cavity. The locking member 10b includes an operating piece 12b and a latch tongue 13b that can move with the operating piece 12b. The operating piece 12b is horizontally slidably arranged in the sliding cavity and protrudes from the side opening of the sliding cavity. The latch tongue 13b and the first retaining part 31b are provided on the operating piece 12b and protrude from the lower opening of the sliding cavity, allowing the latch tongue 13b and the first retaining part 31b to slide within the installation slot. This enables the latch tongue 13b to cooperate with the locking groove 11b and the first retaining part 31b to cooperate with the second retaining part 32b.

[0141] As shown in FIGS. 21 to 25, the interlocking latch 1b is designed as a vertically sliding latch. The upper surface of the first module 100b is provided with an installation slot (not labelled). The first side wall of the installation slot, which is close to the side of the first module 100b, is designed as the mating part 111b, and the locking groove 11b is formed between the mating part 111b and the second side wall of the installation slot. The second retaining part 32b is formed and connected to the upper portion of the second side wall of the installation slot. The second retaining part 32b covers part of the installation slot to form a vertical barrier. The lower portion of the second module 200b is provided with a sliding cavity (not labelled), with openings on the side and bottom of the sliding cavity. The locking member 10b includes an operating piece 12b and a latch tongue 13b that can move with the operating piece 12b. The operating piece 12b is vertically slidably arranged in the sliding cavity and protrudes from the side opening of the sliding cavity. The latch tongue 13b and the first retaining part 31b are provided on the operating piece 12b and protrude from the lower opening of the sliding cavity, allowing the latch tongue 13b and the first retaining part 31b to extend into and retract from the installation slot. This enables the latch tongue 13b to cooperate with the locking groove 11b and the first retaining part 31b to cooperate with the second retaining part 32b.

[0142] In some preferred embodiments, two interlocking latches 1b are provided, located on opposite sides of the first module 100b or the second module 200b. The arrangement direction of the two interlocking latches 1b is parallel to the unlocking direction of the sliding engaging structure 2b. During use, the two interlocking latches 1b can lock the first module 100b and the second module 200b in the displacement direction, thereby enabling dual-side installation of the first module 100b and the second module 200b and enhancing compatibility.

[0143] In some other embodiments, as shown in FIGS. 26 to 39, the interlocking latch 1c includes a locking member 10c and a locking groove 11c. The locking groove 11c is provided on one of the blocking parts (e.g., the second blocking part 22c) of the sliding engaging structure 2c, and the mating part 111c is designed as the side wall of the locking groove 11c. The locking member 10c abuts against the side wall of the locking groove 11c, forming interference between the locking member 10c and the mating part 111c. The locking member 10c is provided on the second module 200c. For example, when the first module 100c and the second module 200c are connected, the locking member 10c and the locking groove 11c are both located on the side positions of the first module 100c and the second module 200c, facilitating the operation of locking and unlocking. Further, the locking member 10c can move relative to the second module 200c (this movement can be set as sliding, meaning the locking member 10c is slidably connected to the second module 200c; or this movement can be set as flipping, meaning the locking member 10c is flip-connected to the second module 200c), allowing the locking member 10c to extend into and retract from the locking groove 11c. When the interlocking latch 1c is in the locked state, the locking member 10c extends into the locking groove 11c. When the interlocking latch 1c is in the unlocked state, the locking member 10c retracts out of the locking groove 11c. By extending and retracting the locking member 10c into and out of the locking groove 11c, the interlocking latch 1c can switch between the locked state and the unlocked state, while simultaneously maintaining and canceling the locked state of the sliding engaging structure 2c.

[0144] Further, the interlocking latch 1c also includes a first elastic member 14c. The first elastic member 14c is connected between the locking member 10c and the second module 200c, and the first elastic member 14c can drive the locking member 10c to move relative to the second module 200c, causing the locking member 10c to move and finally interfere with the locking groove 11c (i.e., the locking member 10c extends into the locking groove 11c), thereby automatically maintaining the interlocking latch 1c in the locked state. When the first module 100c is connected to the second module 200c and the interlocking latch 1c is in the locked state, the locking member 10c and the locking groove 11c are aligned with each other. Under the action of the first elastic member 14c, the locking member 10c is automatically locked in the locking groove 11c.

[0145] Since the locking groove 11c is provided on one of the blocking parts of the sliding engaging structure 2c and the mating part 111c is designed as the side wall of the locking groove 11c, the locking member 10c must be positioned accordingly. In some embodiments, the locking groove 11c is provided on the second blocking part 22c, so the locking member 10c is positioned near the second holding part 24c, facilitating the sliding connection of the second blocking part 22c and the second holding part 24c when the locking member 10c is driven to be locked. Specifically, the locking member 10c includes an operating piece 12c and a latch tongue 13c. The latch tongue 13c is aligned with the locking groove 11c.

[0146] As shown in FIG. 31 and FIG. 37, the second blocking part 22c is provided with an inclined surface 25c facing the unlocking direction of the sliding engaging structure 2c, and the inclined surface 25c is provided on one end of the second blocking part 22c. When the second holding part 24c slides and locks with the second blocking part 22c, the inclined surface 25c facilitates the latch tongue 13c to be depressed when the latch tongue 13c comes into contact with the second blocking part 22c. Under the action of the first elastic member 14c, the latch tongue 13c retracts, allowing the second holding part 24c to continue sliding along the second blocking part 22c until the latch tongue 13c falls into the locking groove 11c. Further, inclined surfaces can be provided on both ends of the second blocking part 22c, thereby allowing the second holding part 24c to be inserted and locked from either side of the second blocking part 22c.

[0147] Below is a detailed explanation of the interlocking latch 1c in conjunction with some specific embodiments.

[0148] In a first embodiment, as shown in FIGS. 26-32, the second module 200c is stacked on top of the first module 100c. The interlocking latch 1c is designed as a flip latch. The locking member 10c includes an operating piece 12c and a latch tongue 13c. The operating piece 12c is connected to the second module 200c and can flip relative to the second module 200c. Specifically, the side of the second module 200c is provided with a flip slot 15c. The middle portion of the operating piece 12c is connected to the flip slot 15c via a flip shaft 16c, allowing the operating piece 12c to flip within the flip slot 15c. The flip shaft 16c extends along the arrangement direction of the first module 100c and the second module 200c. The latch tongue 13c is provided on the operating piece 12c. The first elastic member 14c, which can be a spring, is connected between the operating piece 12c and the second module 200c. Under the action of the first elastic member 14c, the operating piece 12c can drive the latch tongue 13c to automatically flip in the locking direction. Specifically, the first elastic member 14c is arranged at the first end of the operating piece 12c, and the latch tongue 13c is provided at the second end of the operating piece 12c.

[0149] The locking groove 11c is provided on one of the blocking parts (e.g., the second blocking part 22c) of the sliding engaging structure 2c. Under the action of the first elastic member 14c, the operating piece 12c drives the latch tongue 13c to flip into the locking groove 11c, putting the interlocking latch 1c in the locked state, so that the sliding engaging structure 2c is prevented from moving in the unlocking direction, thereby blocking the relative sliding between the first module 100c and the second module 200c. By manually applying force to flip the operating piece 12c in a reverse direction, the latch tongue 13c is driven to move out of the locking groove 11c, putting the interlocking latch 1c in the unlocked state, so that the sliding engaging structure 2c is allowed to move in the unlocking direction, thereby allowing the relative sliding between the first module 100c and the second module 200c.

[0150] Furthermore, one of the holding parts (e.g., the second holding part 24c that cooperates with the second blocking part 22c) of the sliding engaging structure 2c is provided on the operating piece 12c. For example, the second holding part 24c is provided at the second end of the operating piece 12c. Under the action of the first elastic member 14c, the operating piece 12c can drive the second holding part 24c to move until the second holding part 24c interferes with one of the blocking parts (i.e., the second blocking part 22c). In this way, by flipping the operating piece 12c relative to the second module 200c, the latch tongue 13c can be inserted into the locking groove 11c, and meanwhile, the second holding part 24c in the sliding engaging structure 2c can interfere with the second blocking part 22c, thereby enhancing the stability of the cooperation between the sliding engaging structure 2c and the interlocking latch 1c.

[0151] Alternatively, as shown in FIG. 32, multiple ratchet teeth 27c are provided on the blocking part, and the ratchet teeth 27c are arranged along the movement direction of the sliding engaging structure 2c. For example, five, six, or seven ratchet teeth 27c are provided. These multiple ratchet teeth 27c allow the second holding part 24c to move in the locking direction of the sliding engaging structure 2c but prevent the second holding part 24c from moving in the unlocking direction of the sliding engaging structure 2c. Specifically, the locking groove 11c is located between two adjacent ratchet teeth 27c, and these multiple ratchet teeth 27c allow the latch tongue 13c to move in the locking direction of the sliding engaging structure 2c but prevent the latch tongue 13c from moving in the unlocking direction of the sliding engaging structure 2c. Since both the latch tongue 13c and the second holding part 24c are provided on the operating piece 12c, restricting the position of the latch tongue 13c also restricts the position of the second holding part 24c. In this way, during the process of the sliding engaging structure 2c moving from the unlocked state to the locked state, the latch tongue 13c sequentially moves forward over the multiple ratchet teeth 27c until the latch tongue 13c is engaged in the locking groove 11c. However, the latch tongue 13c is restricted from moving backward over the ratchet teeth 27c, thus preventing the sliding engaging structure 2c from moving from the locked state to the unlocked state, further enhancing the structural stability.

[0152] In a second embodiment, as shown in FIGS. 33-39, the second module 200c is stacked on top of the first module 100c. The interlocking latch 1c is designed as a horizontally sliding latch. The locking member 10c includes an operating piece 12c and a latch tongue 13c. The operating piece 12c is connected to the second module 200c and can slide horizontally relative to the second module 200c. Specifically, a sliding cavity (not labelled) is provided on the second module 200c near the first module 100c, with openings on the side and bottom of the sliding cavity. The operating piece 12c is slidably arranged in the sliding cavity and protrudes from the side opening of the sliding cavity. Multiple guide rails (not shown) can be provided between the sliding cavity and the operating piece 12c to guide and limit the sliding direction of the operating piece 12c. The first elastic member 14c, which can be a spring, is connected between the operating piece 12c and the second module 200c. Under the action of the first elastic member 14c, the operating piece 12c can automatically slide in the locking direction, causing the operating piece 12c to protrude from the side opening of the sliding cavity. The latch tongue 13c is provided on the operating piece 12c and protrudes from the bottom opening of the sliding cavity beyond the second module 200c.

[0153] The locking groove 11c is provided on the blocking part (e.g., the second blocking part 22c), and an avoidance slot 26c is provided on the holding part (e.g., the second holding part 24c). When the first module 100c and the second module 200c are aligned, the locking groove 11c and the avoidance slot 26c are also aligned. Under the action of the first elastic member 14c, the operating piece 12c drives the latch tongue 13c to slide horizontally into the locking groove 11c, putting the interlocking latch 1c in the locked state, so that the sliding engaging structure 2c is prevented from moving, thereby blocking the relative sliding between the first module 100c and the second module 200c. By manually applying force to drive the operating piece 12c to slide horizontally, the latch tongue 13c is driven to move from the locking groove 11c to the avoidance slot 26c, putting the interlocking latch 1c in the unlocked state, so that the sliding engaging structure 2c is allowed to move, thereby allowing the relative sliding between the first module 100c and the second module 200c.

[0154] In some other embodiments, as shown in FIGS. 40 to 52, the interlocking latch 1d includes a locking member 10d and a mating part 111d. The locking member 10d is movably provided on the second module 200d, and this movement can be set as sliding or flipping. The mating part 111d is provided on the first module 100d. The locking member 10d and the mating part 111d are designed to interact. By changing the position of the locking member 10d relative to the mating part 111d, the interlocking latch 1d can switch between a locked state and an unlocked state. When the interlocking latch 1d is in the locked state, the locking member 10d interferes with the mating part 111d in the displacement direction of the first module 100d and the second module 200d, thereby restricting the movement of the first module 100d and the second module 200d in the displacement direction and maintaining the sliding engaging structure 2d in the locked state. When the interlocking latch 1d is in the unlocked state, the locking member 10d does not interfere with the mating part 111d, allowing the first module 100d and the second module 200d to move in the displacement direction.

[0155] Specifically, in some embodiments, the mating part 111d is designed as the side wall of a locking groove (not labelled). The locking member 10d abuts against the side wall of the locking groove to form interference between the locking member 10d and the mating part 111d. In other embodiments, the mating part 111d and the locking member 10d can also be designed in other forms of structure. The locking member 10d is provided on the second module 200d. For example, when the first module 100d and the second module 200d are connected, the locking member 10d and the locking groove are both located on the side positions of the first module 100d and the second module 200d, facilitating the operation of locking and unlocking. Further, the locking member 10d can move relative to the second module 200d (this movement can be set as sliding, meaning the locking member 10d is slidably connected to the second module 200d; or this movement can be set as flipping, meaning the locking member 10d is flip-connected to the second module 200d), allowing the locking member 10d to extend into and retract from the locking groove. When the interlocking latch 1d is in the locked state, the locking member 10d extends into the locking groove. When the interlocking latch 1d is in the unlocked state, the locking member 10d retracts out of the locking groove. By extending and retracting the locking member 10d into and out of the locking groove, the interlocking latch 1d can switch between the locked state and the unlocked state, while simultaneously maintaining and canceling the locked state of the sliding engaging structure 2d.

[0156] Further, the interlocking latch 1d also includes a first elastic member (not shown). The first elastic member is connected between the locking member 10d and the second module 200d, and the first elastic member can drive the locking member 10d to move relative to the second module 200d, causing the locking member 10d to move and finally interfere with the locking groove (i.e., the locking member 10d extends into the locking groove), thereby automatically maintaining the interlocking latch 1d in the locked state. When the first module 100d is connected to the second module 200d and the interlocking latch 1d is in the locked state, the locking member 10d and the locking groove are aligned with each other. Under the action of the first elastic member, the locking member 10d is automatically locked in the locking groove.

[0157] Specifically, the locking member 10d includes an operating piece 12d and a latch tongue 13d. The operating piece 12d can move relative to the second module 200d. The latch tongue 13d is formed on the operating piece 12d, and the operating piece 12d can drive the latch tongue 13d to extend into and retract from the mating part 111d. The interlocking latch 1d can be designed as a flip latch or a sliding latch, meaning the movement of the operating piece 12d relative to the second module 200d can be set as a flipping motion or a vertically sliding motion.

[0158] In some embodiments, the interlocking latch 1d includes a self-locking mechanism. The self-locking mechanism is provided on the first module 100d and the second module 200d.A part of the self-locking mechanism is provided on the first module 100d, and the other part of the self-locking mechanism is provided on the second module 200d, or multiple parts of the self-locking mechanism are all be provided at different positions on the second module 200d. Specifically, a part of the self-locking mechanism is provided on the locking member 10d and can move together with the locking member 10d. The locking member 10d can drive the self-locking mechanism to move and interfere with the second module 200d in the unlocking direction of the second module 200d, thereby self-locking the second module 200d. The locking member 10d can also drive the self-locking mechanism to move and not interfere with the second module 200d in the unlocking direction of the second module 200d, thereby releasing the second module 200d from self-locking.

[0159] In some embodiments, the self-locking mechanism includes a self-locking member 15d and a self-locking groove 16d. One of the self-locking member 15d and the self-locking groove 16d is provided on the locking member 10d, and the other is provided on the second module 200d. By engaging the self-locking member 15d with the self-locking groove 16d, the second module 200d is self-locked. In other embodiments, the self-locking member 15d and the self-locking groove 16d can also be designed in other forms of structure.

[0160] Specifically, the first module 100d and the second module 200d each have two box bodies stacked vertically. Here, among the two box bodies, the one located on top is defined as the first box body, and the one located on the bottom is defined as the second box body. The first box body and the second box body are connected to each other. For example, one side of the first box body and the second box body is hinged, and the other side is connected by the self-locking mechanism. When the self-locking mechanism is in the unlocked state, the second module 200d can be opened and closed by rotating the first box body relative to the second box body.

[0161] Below is a detailed explanation of the interlocking latch 1d in conjunction with some specific embodiments.

[0162] As shown in FIGS. 40-42, in a first embodiment, the first module 100d is stacked on top of the second module 200d. The sliding engaging structure 2d includes four blocking parts 21d and four holding parts 22d. The four blocking parts 21d are respectively arranged on opposite sides of the first module 100d, while the four holding parts 22d are respectively arranged on opposite sides of the second module 200d. By engaging each blocking part 21d with a corresponding holding part 22d in a one-to-one manner, the first module 100d and the second module 200d are restricted from being separated in a direction away from each other, while the first module 100d and the second module 200d are allowed to move from the locked state to the unlocked state in the displacement direction.

[0163] The interlocking latch 1d is in the form of a combination of a sliding latch and a self-locking mechanism. The self-locking mechanism can achieve self-locking of the second module 200d. For example, the self-locking mechanism includes a self-locking member 15d and a self-locking groove 16d. The self-locking member 15d is provided on the second box body of the second module 200d, while the self-locking groove 16d is provided on the first box body of the second module 200d. The second module 200d is self-locked by engaging the self-locking member 15d with the self-locking groove 16d. The sliding latch includes an operating piece 12d, a latch tongue 13d, and a mating part 111d. The mating part 111d is designed as a locking groove. The bottom surface of the first module 100d is provided with two protrusions 101 spaced apart from each other, and the locking groove is formed between the two protrusions 101. The locking groove faces the second module 200d. The operating piece 12d is slidably provided on the self-locking member 15d, and the latch tongue 13d is provided on the operating piece 12d and can slide up and down with the operating piece 12d relative to the second module 200d, enabling the latch tongue 13d to extend into and retract from the locking groove, thereby achieving the switching of the interlocking latch 1d between the locked state and the unlocked state.

[0164] As shown in FIGS. 43-45, in a second embodiment, the first module 100d is stacked on top of the second module 200d. The sliding engaging structure 2d is designed as a claw hook structure, including two blocking parts 21d and two holding parts 22d. The two blocking parts 21d are respectively provided on opposite sides of the bottom surface of the first module 100d, while the two holding parts 22d are respectively provided on opposite sides of the top surface of the second module 200d. The two blocking parts 21d protrude from the first module 100d and face in the same direction, and the two holding parts 22d protrude from the second module 200d and face in the same direction, but the facing directions of the blocking parts 21d and the holding parts 22d are opposite. By engaging each blocking part 21d with a corresponding holding part 22d in a one-to-one manner, the first module 100d and the second module 200d are restricted from being separated in a direction away from each other, while the first module 100d and the second module 200d are allowed to move from the locked state to the unlocked state in the displacement direction.

[0165] The bottom surface of the first module 100d is provided with four first guiding parts 23d, and the top surface of the second module 200d is provided with four second guiding parts 24d. The four first guiding parts 23d and the four second guiding parts 24d are paired one-to-one. When the first module 100d and the second module 200d are connected, the first guiding parts 23d and the second guiding parts 24d can restrict the relative displacement direction between the first module 100d and the second module 200d, so that the displacement direction of the first module 100d and the second module 200d is the unlocking direction or the locking direction of the sliding engaging structure 2d, that is, the direction in which the two holding parts 22d or blocking parts 21d are arranged.

[0166] The interlocking latch 1d is in the form of a combination of a flip latch and a self-locking mechanism. The flip latch includes an operating piece 12d, a latch tongue 13d, and a mating part 111d. The mating part 111d is designed as a locking groove. The side of the first module 100d is provided with a through-slot (not labelled), and the bottom of the through-slot forms the locking groove. The operating piece 12d is rotatably connected to the second box body of the second module 200d. The latch tongue 13d is provided on the operating piece 12d and can rotate with the operating piece 12d relative to the second module 200d, enabling the latch tongue 13d to extend into and retract from the locking groove, thereby achieving the switching of the interlocking latch 1d between the locked state and the unlocked state. The self-locking mechanism can achieve the self-locking of the second module 200d. For example, the self-locking mechanism includes a self-locking member 15d and a self-locking groove 16d. The self-locking member 15d is provided on the second box body of the second module 200d, while the self-locking groove 16d is provided on the first box body of the second module 200d. The second module 200d is self-locked by engaging the self-locking member 15d with the self-locking groove 16d. Specifically, the self-locking member 15d and the self-locking groove 16d are formed between the first box body of the second module 200d and the operating piece 12d.

[0167] As shown in FIGS. 46-48, in a third embodiment, the first module 100d is stacked on top of the second module 200d. The sliding engaging structure 2d is designed as a claw hook structure, including two blocking parts 21d and two holding parts 22d. The two blocking parts 21d are respectively provided on opposite sides of the bottom surface of the first module 100d, while the two holding parts 22d are respectively provided on opposite sides of the top surface of the second module 200d. The two blocking parts 21d protrude from the first module 100d and face in the same direction, and the two holding parts 22d protrude from the second module 200d and face in the same direction, but the facing directions of the blocking parts 21d and the holding parts 22d are opposite. By engaging each blocking part 21d with a corresponding holding part 22d in a one-to-one manner, the first module 100d and the second module 200d are restricted from being separated in a direction away from each other, while the first module 100d and the second module 200d are allowed to move from the locked state to the unlocked state in the displacement direction.

[0168] The interlocking latch 1d is in the form of a combination of a flip latch and a self-locking mechanism. The flip latch includes a locking member 10d and a mating part 111d. The side of the first module 100d is provided with a through-slot (not labelled), and the bottom of the through-slot is provided with a protrusion which forms as the mating part 111d. The locking member 10d is rotatably connected to the second box body of the second module 200d, and the locking member 10d is provided with a recess (not labelled) that matches the protrusion. Through the engagement between the protrusion and the recess, the locking member 10d is engaged with the mating part 111d, thereby placing the interlocking latch 1d in the locked state. The self-locking mechanism can achieve the self-locking of the second module 200d. For example, the self-locking mechanism includes a self-locking member 15d and a self-locking groove 16d. The self-locking groove 16d is provided on the first box body of the second module 200d, while the self-locking member 15d is provided on the locking member 10d and can rotate with the locking member 10d relative to the second module 200d. The second module 200d is self-locked by engaging the self-locking member 15d with the self-locking groove 16d.

[0169] As shown in FIGS. 49-52, in a fourth embodiment, the first module 100d is stacked on top of the second module 200d. The sliding engaging structure 2d is designed as a claw hook structure, including two blocking parts 21d and two holding parts 22d. The two blocking parts 21d are respectively provided on opposite sides of the bottom surface of the first module 100d, and the two holding parts 22d are respectively provided on opposite sides of the top surface of the second module 200d. The two blocking parts 21d protrude from the first module 100d and face in the same direction, and the two holding parts 22d protrude from the second module 200d and face in the same direction, but the facing directions of the blocking parts 21d and the holding parts 22d are opposite. By engaging each blocking part 21d with a corresponding holding part 22d in a one-to-one manner, the first module 100d and the second module 200d are restricted from being separated in a direction away from each other, while the first module 100d and the second module 200d are allowed to move from the locked state to the unlocked state in the displacement direction.

[0170] The interlocking latch 1d includes an operating piece 12d, a latch ring 30, a self-locking groove 16d, and a mating part 111d. The mating part 111d is designed as a locking groove. The side of the first module 100d is provided with a through-slot (not labelled), and the bottom of the through-slot forms the locking groove. The self-locking groove 16d is provided on the first box body 201 of the second module 200d and faces the first module 100d. One end of the operating piece 12d is rotatably connected to the second box body 202 of the second module 200d, and the latch ring 30 is connected to the middle of the operating piece 12d. The self-locking member 15d and the latch tongue 13d are formed at the end of the latch ring 30 away from the operating piece 12d. By rotating the operating piece 12d, the self-locking member 15d on the latch ring 30 can be embedded into the self-locking groove 16d, and at the same time, the latch tongue 13d on the latch ring 30 can be embedded into the locking groove, thereby achieving the self-locking of the second module 200d and the interlocking of the sliding engaging structure 2d.

[0171] In some other embodiments, as shown in FIGS. 53 to 60, the sliding engaging structure 2e is the same as that described in the aforementioned embodiments, including a first sliding engaging structure and a second sliding engaging structure. The first sliding engaging structure includes a first blocking part 21e and a first holding part 23e, while the second sliding engaging structure includes a second blocking part 22e and a second holding part 24e. The details will not be repeated here. The difference lies in the structure of the interlocking latch 1e. The interlocking latch 1e further includes a retaining part 15e. The retaining part 15e is provided on the first module 100e and cooperates with the locking member 10e. When the locking member 10e interferes with the retaining part 15e, the retaining part 15e prevents the locking member 10e from moving in the locking direction of the interlocking latch 1e, thereby keeping the interlocking latch 1e in the unlocked state, that is, the interlocking latch 1e is held in the unlocked state.

[0172] Specifically, the locking member 10e includes an operating piece 11e and a latch tongue 12e. The operating piece 11e is movably connected to the second module 200e. The operating piece 11e constitutes the main body of the locking member 10e. The latch tongue 12e is provided on the operating piece 11e, and the operating piece 11e can drive the latch tongue 12e to move relative to the second module 200e. When the latch tongue 12e interferes with the mating part 16e, the interlocking latch 1e is in the locked state, thereby preventing the sliding engaging structure 2e from moving in its unlocking direction and achieving mutual locking between the sliding engaging structure 2e and the interlocking latch 1e. When the latch tongue 12e interferes with the retaining part 15e, the interlocking latch 1e is kept in the unlocked state.

[0173] With this arrangement, under the cooperation of the mating part 16e and the latch tongue 12e, the interlocking latch 1e can be kept in the locked state to restrict the sliding engaging structure 2e from moving in the unlocking direction. By combining the sliding engaging structure 2e and the interlocking latch 1e, the first module 100e and the second module 200e are restricted from moving along the displacement direction and from being separated in a direction away from each other, thereby achieving mutual locking between the first module 100e and the second module 200e. This facilitates the organization and storage of the modules and enhances the user experience. Under the cooperation of the retaining part 15e and the latch tongue 12e, the interlocking latch 1e can be kept in the unlocked state without applying a retaining force to the interlocking latch 1e, allowing the sliding engaging structure 2e to move in the unlocking direction. This is conducive to the quick disassembly of the first module 100e and the second module 200e, making the operation simple, time-saving, and labor-saving.

[0174] As shown in FIG. 57, in some embodiments, the interlocking latch 1e includes a locking groove 17e. The locking groove 17e is provided on the first module 100e, and the mating part 16e is designed as the inner side wall of the locking groove 17e. Specifically, the mating part 16e is the inner side wall of the locking groove 17e in the unlocking direction of the sliding engaging structure 2e. When the interlocking latch 1e is in the locked state, the locking member 10e abuts against the aforementioned inner side wall of the locking groove 17e to form interference between the locking member 10e and the mating part 16e. In some embodiments, the mating part 16e is one inner side wall of the locking groove 17e in the displacement direction. In other embodiments, the mating part 16e can also be two inner side walls of the locking groove 17e in the displacement direction.

[0175] The retaining part 15e is the outer side wall of the locking groove 17e in the unlocking direction of the interlocking latch 1e. When the interlocking latch 1e is in the unlocked state, the locking member 10e disengages from the locking groove 17e and is located outside the locking groove 17e. Then, the locking member 10e moves relative to the locking groove 17e in the locking direction of the interlocking latch 1e, causing the locking member 10e to abut against the aforementioned outer side wall of the locking groove 17e to form interference between the locking member 10e and the retaining part 15e. Preferably, the unlocking direction of the sliding engaging structure 2e is perpendicular to the locking direction of the interlocking latch 1e, and the locking groove 17e is designed to have a rectangular shape.

[0176] In some embodiments, the interlocking latch 1e also includes a first elastic member 13e. The first elastic member 13e is connected between the locking member 10e and the second module 200e, and the first elastic member 13e can drive the locking member 10e to move relative to the second module 200e, causing the locking member 10e to move and finally interfere with the mating part 16e (i.e., the locking member 10e extends into the locking groove 17e), thereby automatically maintaining the interlocking latch 1e in the locked state. When the first module 100e is connected to the second module 200e and the interlocking latch 1e is in the locked state, the locking member 10e and the locking groove 17e are aligned with each other. Under the action of the first elastic member 13e, the locking member 10e is automatically locked in the locking groove 17e.

[0177] The locking member 10e includes an operating piece 11e and a latch tongue 12e, and the first elastic member 13e is disposed between the operating piece 11e and the second module 200e. For example, the first elastic member 13e can be a spring, with one end of the first elastic member 13e abutting against the second module 200e and the other end abutting against the operating piece 11e. Under the action of the first elastic member 13e, the operating piece 11e moves relative to the second module 200e, driving the latch tongue 12e to move relative to the second module 200e, thereby causing the latch tongue 12e to move and finally interfere with the mating part 16e on the first module 100e, thereby automatically maintaining the interlocking latch 1e in the locked state.

[0178] In an alternative embodiment, the interlocking latch 1e dose not include the first elastic member 13e, and the interlocking latch 1e can be manually reset to the locked state. For example, a damping structure can be provided between the locking member 10e and the second module 200e. The damping structure can hold the locking member 10e in a specific position so as to ensure the reliability of the locked state of the locking member 10e.

[0179] Further, the interlocking latch 1e also includes a second elastic member 14e. The second elastic member 14e is disposed between the operating piece 11e and the latch tongue 12e. Under the action of the second elastic member 14e, the latch tongue 12e can protrude relative to the operating piece 11e. When the interlocking latch 1e moves to the locked state, under the action of the second elastic member 14e, the latch tongue 12e automatically moves to a position where it interferes with the mating part 16e, thereby restricting the movement of the first module 100e and the second module 200e in the displacement direction. When the interlocking latch 1e moves in its unlocking direction, under the action of the second elastic member 14e, the latch tongue 12e is compressed by the aforementioned outer side wall of the locking groove 17e and retracts from the locking groove 17e. After the latch tongue 12e disengages from the locking groove 17e and is located outside the locking groove 17e, the latch tongue 12e extends under the action of the second elastic member 14e and automatically moves to a position where it interferes with the retaining part 15e, thereby restricting the interlocking latch 1e from moving in the locking direction. At this time, the latch tongue 12e abuts against the retaining part 15e under the action of the first elastic member 13e. In this way, under the action of the second elastic member 14e, the latch tongue 12e can automatically maintain at the corresponding interference positions and interfere with either the mating part 16e or the retaining part 15e, enhancing the stability and reliability of the interlocking latch 1e.

[0180] When the operating piece 11e drives the latch tongue 12e to move in the unlocking direction of the interlocking latch 1e, the latch tongue 12e and the locking groove 17e can be cooperated through an inclined surface. Here, the inclined surface can be formed on the latch tongue 12e, inside the locking groove 17e, or on both the latch tongue 12e and the locking groove 17e. In some embodiments, the latch tongue 12e is provided with a first inclined surface 121e, which is located on the side of the latch tongue 12e facing the unlocking direction of the interlocking latch 1e. Alternatively, the aforementioned outer side wall of the locking groove 17e is provided with a second inclined surface 171e, which is arranged on the side of the aforementioned outer side wall facing the locking groove 17e. In some embodiments, the latch tongue 12e is provided with a first flat surface 122e on the side facing its locking direction. When the first flat surface 122e interferes with the retaining part 15e, the interlocking latch 1e is kept in the unlocked state. That is, the first flat surface 122e and the first inclined surface 121e are located on opposite sides of the latch tongue 12e.

[0181] When the operating piece 11e drives the latch tongue 12e to move in the unlocking direction of the interlocking latch 1e (here, the unlocking direction of the interlocking latch 1e is defined as the first direction, and the second direction is perpendicular to the first direction), under the action of the first inclined surface 121e and / or the second inclined surface 171e, the latch tongue 12e compresses the second elastic member 14e in the second direction, and the latch tongue 12e is disengaged from the locking groove 17e. Subsequently, the second elastic member 14e returns to its original shape and drives the latch tongue 12e to move in the second direction until it interferes with the retaining part 15e. Finally, under the action of the first elastic member 13e, the first flat surface 122e of the latch tongue 12e abuts against the retaining part 15e, thereby keeping the interlocking latch 1e in the unlocked state. In this way, through the inclined surface design between the latch tongue 12e and the retaining part 15e, the smoothness of the interlocking latch 1e during unlocking can be enhanced.

[0182] Below is a detailed explanation of the interlocking latch 1a in conjunction with some specific embodiments.

[0183] As shown in FIGS. 56 and 59, in a first embodiment, the interlocking latch 1e is designed as a flip latch. The locking member 10e includes an operating piece 11e and a latch tongue 12e. The operating piece 11e is connected to the second module 200e and can flip relative to the second module 200e. Specifically, a flip slot 19e is provided on the side of the second module 200e. The middle portion of the operating piece 11e is connected to the flip slot 19e via a flip shaft 18e, allowing the operating piece 11e to flip within the flip slot 19e. The direction of the flip shaft 18e is perpendicular to the arrangement direction of the first module 100e and the second module 200e, causing the first end of the operating piece 11e to be closer to the first module 100e relative to the second end. The latch tongue 12e is provided on the first end of the operating piece 11e. The first elastic member 13e, which can be a spring, is connected between the second end of the operating piece 11e and the bottom wall of the flip slot 19e. Under the action of the first elastic member 13e, the operating piece 11e can drive the latch tongue 12e to automatically flip in its locking direction, thereby automatically maintaining the locking member 10e in the locked state.

[0184] In a second embodiment, the interlocking latch 1e is designed as a horizontally sliding latch. The locking member 10e includes an operating piece 11e and a latch tongue 12e. The operating piece 11e is connected to the second module 200e and can slide horizontally relative to the second module 200e. The direction of horizontal sliding is the displacement direction of the first module 100e and the second module 200e. Specifically, a sliding cavity is provided on the second module 200e, and the operating piece 11e is slidably connected within the sliding cavity, allowing the operating piece 11e to slide horizontally within the sliding cavity. Horizontal guide rails can be provided between the operating piece 11e and the sliding cavity to guide and limit the relative sliding between the operating piece 11e and the sliding cavity. The extension direction of the horizontal guide rails is perpendicular to the arrangement direction of the first module 100e and the second module 200e. The latch tongue 12e is provided on the side of the operating piece 11e facing the second module 200e. The first elastic member 13e is connected between the operating piece 11e and the second module 200e. For example, the first elastic member 13e can be a spring and is connected between the operating piece 11e and the sliding cavity. Under the action of the first elastic member 13e, the operating piece 11e can drive the latch tongue 12e to automatically slide in its locking direction.

[0185] In this solution, the latch tongue 12e is connected to the operating piece 11e in such a way that it can move up and down. Under the action of the second elastic member 14e, the latch tongue 12e protrudes from the operating piece 11e and can interfere with either the mating part 16e or the retaining part 15e. The connection between the latch tongue 12e and the operating piece 11e can be a flip connection, a sliding connection, or an integral connection. Below is a detailed explanation of the connection methods between the latch tongue 12e and the operating piece 11e in conjunction with some specific embodiments.

[0186] In a first preferred embodiment, the latch tongue 12e is connected to the operating piece 11e in such a way that it can flip up and down. The second elastic member 14e can drive the latch tongue 12e to rotate relative to the operating piece 11e, causing the latch tongue 12e to protrude from the operating piece 11e. Specifically, a flip cavity is provided in the operating piece 11e, and the latch tongue 12e is designed in a wedge shape. The first end of the latch tongue 12e is pivoted within the flip cavity. The second elastic member 14e, which can be a spring, is disposed between the second end of the latch tongue 12e and the bottom wall of the flip cavity. The second elastic member 14e drives the latch tongue 12e to protrude from the flip cavity and interfere with either the mating part 16e or the retaining part 15e. When the interlocking latch 1e is in the locked state, the first inclined surface 121e of the latch tongue 12e faces the retaining part 15e, and the second flat surface 123e of the latch tongue 12e faces the mating part 16e. When the interlocking latch 1e is in the unlocked state, the first flat surface 122e of the latch tongue 12e faces the retaining part 15e.

[0187] In a second preferred embodiment, as shown in FIG. 60, the latch tongue 12e is connected to the operating piece 11e in such a way that it can slide up and down. The second elastic member 14e can drive the latch tongue 12e to slide up and down relative to the operating piece 11e, causing the latch tongue 12e to protrude from the operating piece 11e. Specifically, a sliding slot 111e is provided in the operating piece 11e, and the latch tongue 12e is located within the sliding slot 111e. The second elastic member 14e, which can be a spring, is disposed between the latch tongue 12e and the bottom wall of the sliding slot 111e. The second elastic member 14e drives the latch tongue 12e to protrude from the sliding slot 111e and interfere with either the mating part 16e or the retaining part 15e. When the interlocking latch 1e is in the locked state, the first inclined surface 121e of the latch tongue 12e faces the retaining part 15e, and the second flat surface 123e of the latch tongue 12e faces the mating part 16e. When the interlocking latch 1e is in the unlocked state, the first flat surface 122e of the latch tongue 12e faces the retaining part 15e.

[0188] In a third preferred embodiment, the latch tongue 12e and the second elastic member 14e are integrally formed with the operating piece 11e. The second elastic member 14e drives the latch tongue 12e to protrude from the operating piece 11e through its own elastic potential energy. Specifically, a receiving cavity is provided in the operating piece 11e, and the latch tongue 12e is connected to the receiving cavity through the second elastic member 14e. The latch tongue 12e and the second elastic member 14e are integrally formed. The second elastic member 14e, through its own elastic deformation, drives the latch tongue 12e to protrude from the receiving cavity and interfere with either the mating part 16e or the retaining part 15e. When the interlocking latch 1e is in the locked state, the first inclined surface 121e of the latch tongue 12e faces the retaining part 15e, and the second flat surface 123e of the latch tongue 12e faces the mating part 16e. When the interlocking latch 1e is in the unlocked state, the first flat surface 122e of the latch tongue 12e faces the retaining part 15e.
