Abstract
Description
Technical Field
[0001] This application relates to the field of goods storage and transportation, and more particularly to a container assembly. Background Technology
[0002] Containers are common storage and transportation tools in daily life. Stackable container combinations, which combine multiple containers together, are not only convenient for storage but also easy to manage and carry, making them an important method for users to store and transport goods. However, existing stackable container combinations have relatively complex unlocking methods and high structural costs. Utility Model Content
[0003] This application provides a container assembly with a simple structure and low cost.
[0004] Specifically, this application provides a container assembly including a first container and a second container stacked along a first direction. In other embodiments, the first container and the second container have different sizes, i.e., the first container can be combined with second containers of different sizes. The first container includes a first upper cover and a first lower cover, which are assembled to form a first receiving space. The second container includes a second upper cover and a second lower cover, which are assembled to form a second receiving space. The first lower cover includes a first mating structure, and the second upper cover includes a second mating structure. The first mating structure and the second mating structure are connected to limit the first container and the second container in a first direction. The first container includes a locking member disposed on the first lower cover. The locking member is slidably mounted on the first lower cover and includes a locking portion. The second upper cover also includes a third mating structure. The locking member has a first position and a second position. When the locking member is in the first position, the locking portion is coupled to the third mating structure, limiting the first container and the second container in the first and second directions. The second direction is the direction in which the first container and the second container are assembled, and the second direction is perpendicular to the first direction. When the locking member is in the second position, the locking portion is discoupled from the third mating structure.
[0005] Furthermore, the locking member slides along a third direction, which is perpendicular to the first direction, the locking part extends along a second direction, and the third mating structure extends along the second direction.
[0006] Furthermore, the locking element includes an operating portion that defines at least one finger contact surface.
[0007] Furthermore, the first mating structure is disposed at the bottom of the first lower cover, and the second and third mating structures are disposed at the top of the second upper cover.
[0008] Furthermore, the second upper cover has a second top surface, the second mating structure is recessed from the second top surface into the second lower cover, and the third mating structure does not extend beyond the second top surface.
[0009] Furthermore, the first lower cover has a recessed area formed along the second direction, and the locking member is located in the recessed area, and the locking member does not extend beyond the outer contour of the first lower cover.
[0010] Furthermore, the second mating structure has a lower surface parallel to the second top surface, and the third mating structure is spaced apart from the lower surface in a first direction. When the locking member is in the first position, the locking part is located between the third mating structure and the lower surface.
[0011] Furthermore, the first mating structure is formed as a protruding structure, and the second mating structure is formed as a recessed structure, wherein the recessed structure and the protruding structure are assembled along the second direction to form a mating structure.
[0012] In this application, the rotation of the locking element enables the unlocking and locking of the lower lid of one container with the upper lid of another container. The structure is simple and the cost is low. Attached Figure Description

[0020] Please combine Figures 1 to 5 This application provides a container assembly 1000, which includes a first container 100 and a second container 200 stacked along a first direction Y. If necessary, a third container, a fourth container, and other containers can be stacked. The first container 100 includes a first upper cover 11 and a first lower cover 12, which are assembled to form a first receiving space. The first upper cover 11 and the first lower cover 12 are locked by a first latch (not shown). The second container 200 includes a second upper cover 21 and a second lower cover 22, which are assembled to form a second receiving space. The second upper cover 21 and the second lower cover 22 are locked by a second latch 24.
[0021] Please combine Figures 2 to 4The first lower cover 12 includes a first mating structure 121, and the second upper cover 21 includes a second mating structure 211. The first mating structure 121 and the second mating structure 211 are mated together to limit the first container 100 and the second container 200 in a first direction. Optionally, the first mating structure 121 is a protruding structure, and the second mating structure 211 is a recessed structure. The protruding structure and the recessed structure are shape-locked to achieve positioning in the first direction. Specifically, the protruding structure is approximately L-shaped, and the recessed structure includes a recess 2111 and a hole 2112 communicating with the recess. The protruding structure is accommodated within the recess 2111 and the hole 2112.
[0022] Combination Figure 5 The first container 100 further includes a locking member 13 disposed on the first lower cover 12. The locking member 13 is slidably mounted on the first lower cover 12 and includes a locking portion 131. The second upper cover 21 includes a third mating structure 212. The locking member 13 has a first position and a second position. When the locking member 13 is in the first position, the locking portion 131 is shape-coupled with the third mating structure 212, limiting the first container 100 and the second container 200 in the first direction Y and the second direction X. Combined with the locking of the first mating structure 121 and the second mating structure 211, the first container 100 and the second container 200 are reliably stacked. The second direction X is the direction in which the first container 100 and the second container 200 are assembled, and the second direction X is perpendicular to the first direction Y (since it is unlikely to be perfectly horizontally installed in practice, the perpendicularity here can be understood as 80° to 100°). When the locking member 13 is in the second position, the locking part 131 is decoupled from the third mating structure 212, allowing the first container 100 to disengage from the second container 200 in the opposite direction of the second direction X.
[0023] Optionally, the locking part 131 slides along a third direction Z, which is perpendicular to the first direction Y, and the locking part 131 extends along a second direction X, and the third mating structure extends along the second direction X. The locking member 13 includes an operating part 134, which at least defines a finger contact surface 1341.
[0024] The first mating structure 121 is disposed on the top of the first lower cover 12, and the second mating structure 211 and the third mating structure 212 are disposed on the bottom of the second upper cover 21. The second upper cover 21 has a second top surface 210, the second mating structure 211 is recessed from the second top surface 210 toward the second lower cover 22, and the third mating structure 212 does not extend beyond the second top surface 210, so that the placement of the third mating structure 212 does not affect the internal space of the container. The second mating structure 211 has a lower surface 2110 parallel to the second top surface 210, and the third mating structure 212 is spaced apart from the lower surface 2110 in the first direction X. When the locking member 13 is in the first position, the locking part 131 is located between the third mating structure 212 and the lower surface 2110.
[0025] The first lower cover 12 has a recessed area 124 formed along the second direction. The locking member 13 is located in the recessed area 124. The locking member 13 does not exceed the outer contour of the first lower cover 12, so that the locking member 13 is not easy to collide with other objects, thus causing mis-locking or false locking.
[0026] In this application, the rotating housing of the locking component enables the unlocking and locking of the lower cover of one container with the upper cover of another container, without the need for other components (such as a return spring), resulting in a simple structure and low cost.
[0027] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Although this application has disclosed the preferred embodiment as above, it is not intended to limit this application. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this application. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the content of the technical solution of this application shall still fall within the scope of the technical solution of this application.
