In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

Furthermore, repeated reference numerals or designations may be used in the various embodiments. These repetition are for the purpose of simplicity and clarity of presentation and do not in itself dictate a relationship between the various embodiments or configurations discussed.

In the various illustrations of the application, certain dimensions of structures or portions may be exaggerated relative to other structures or portions for convenience of illustration, and thus serve only to illustrate the basic structure of the inventive subject matter.

As shown in fig. 1 to 5, the present invention provides a container 100 having an external hanging device 50, the container 100 being generally rectangular and comprising a base frame 10, two side walls 30 extending upwardly from the base frame 10, and front, rear and top walls. In the present invention, the extending direction of the side wall 30 is the length direction of the container 100, and the extending direction of the end wall is the width direction. In the present invention, the container 100 is provided with a top door, and thus the top wall is the door body 40.

The underframe 10 of the container 100 includes a bottom side rail 2 disposed along the rim of the underframe 10, and the side walls 30 extend upward from the bottom side rail 2. The bottom chassis 10 is formed with a recess structure 3 recessed inward from the outer edge of the bottom side member 2, and in the first state, the plug-in device 50 is accommodated in the recess structure 3 without protruding from the outer edge of the bottom side member 2.

Thus, in the present invention, by providing the recess structure 3 on the bottom side member 2, it is possible to allow the external hanging device 50 to be accommodated in the recess structure 3 without protruding the outer edge of the bottom side member 2. The container 100, as a whole, even if fitted with the plug-in device 50, is unchanged in size as a whole, so that standard sizes can still be met. During the transportation and assembly of the container 100, the external hanging device 50 will not affect the container 100, but the container 100 can still use the functions of the external hanging device 50, so that the production and transportation efficiency can be greatly improved.

Of course, the chassis 10 further includes a main board 1, the main board 1 is a steel floor, and the bottom side beams 2 are disposed along edges of the main board 1 in a length direction.

As described above, the recess structure 3 is formed on the bottom chassis 10 to be recessed inward from the outer edge of the bottom side member 2, and the recess structure 3 is different in size depending on the size of the external hanging device 50. Specifically, two specific embodiments are provided in the present invention.

In the first embodiment, the recess structure 3 is provided on the bottom side member 2 and is formed by being recessed inward from the outer edge thereof, and the recess depth of the recess structure 3 is smaller than the width of the bottom side member 2. In the present first embodiment, the recess structure 3 is provided only on the bottom side member 2, and does not laterally penetrate the bottom side member 2. In this embodiment, the plug-in device 50 with a smaller structure is applicable.

In the second embodiment, the recess depth of the recess structure 3 is not smaller than the width of the bottom side member 2. Since, as shown in fig. 3, the bottom side member 2 is generally slightly higher than the main plate 1 of the bottom chassis 10 in the height direction, the recess structure 3 extends over the bottom chassis 10. Thus, if the recess depth of the recess structure 3 is not smaller than the width of the bottom side member 2, both cases are included.

The first is that the recess depth of the recess structure 3 is equal to the width of the bottom side beam 2, the recess structure 3 just penetrates through the bottom side beam 2, and the external hanging device 50 can be contained in the recess structure 3 or can extend to the inside of the container 100 without interfering with the main board 1.

And secondly, as shown in fig. 1, the recess depth of the recess structure 3 is larger than the width of the bottom side beam 2, so that the recess structure 3 also extends to part of the main board 1. In this case, the space of the recess 3 in which the plug-in device 50 can be accommodated is larger, and the plug-in device 50 can be further extended in the vertical direction.

Since in both of the above embodiments, it is necessary to provide the recess structure 3 on the bottom side member 2, the structure of the bottom side member 2 is not necessarily a complete side member structure. Therefore, in the present invention, the underframe 10 further includes a reinforcement member 21, as shown in fig. 2, the reinforcement member 21 includes a first fixing portion 211, a connecting portion 212, and a second fixing portion 213 sequentially connected, and in the longitudinal direction of the container 100, the connecting portion 212 spans the recess structure 3, and the first fixing portion 211 and the second fixing portion 213 are fixed to the inner edge of the bottom side beam 2.

That is, at least the first fixing portion 211 and the second fixing portion 213 of the reinforcing member 21 are fixed to the inner edge of the bottom beam 2 and are fixed to two sides of the recess structure 3, so that the bottom beam 2 can be reinforced, the influence of the recess structure 3 on the bottom beam 2 on the strength of the bottom beam 2 can be prevented, and the safety and stability of the chassis 10 of the container 100 can be ensured.

Further, as shown in fig. 2, the recessed structure 3 extends into the reinforcement 21. Specifically, the recess structure 3 includes a first recess 31 provided in the bottom rail 2 and a second recess 32 formed by further recessing the first recess 31 toward the connecting portion 212.

In this embodiment, first, the width of the connecting portion 212 is sufficient and the second recess 32 may be formed, so that the reinforcement member 21 may further provide a receiving space for the external hanging device 50, and the connecting portion 212 may still span across the two sides of the recess structure 3, so as to play a role in reinforcing the bottom side member 2.

As shown in fig. 2, the reinforcing member 21 has a U-shaped structure. Of course, if the space provided by the recess structure 3 for the external hanging device 50 is enough, and does not need to extend into the reinforcing member 21, the reinforcing member 21 is completely fixedly disposed against the bottom side member 2, which also achieves the object of the present invention.

In addition, the reinforcing member 21 is also fixed to the main plate 1, and in this embodiment, the recessed structure 3 extends not only in the lateral direction but also in the longitudinal direction, and is provided so as to penetrate the bottom side member 2 from top to bottom. The recess 3 extends into the main board 1 as well as into the connecting portion 212, so that the recess 3 further includes a third recess (not numbered) extending from the first recess 31 further into the main board 1, the third recess being flush with an inner wall of the second recess 32 in a vertical direction.

The concave structures 3 are arranged on the two bottom side beams 2 in pairs, the bottom frame 10 further comprises a reinforcing beam 22, and two ends of the reinforcing beam 22 are respectively connected to two reinforcing pieces 21 arranged in pairs. As shown in fig. 1, the recess structures 3 are provided in pairs and four are provided at the two bottom side members 2, respectively, so that four of the external hanging devices 50 can be accommodated. And, the recessed structures 3 on the two bottom side members 2 are provided correspondingly, and the reinforcing members 22 extend in a direction parallel to the end walls.

Of course, the reinforcing beam 22 is also fixed on the main board 1, so that the reinforcing beam 22 can further provide support for the reinforcing member 21, ensure that the bottom side beam 2 is broken by the concave structure 3 but still has high stability, ensure the safety of the overall structure of the container 100, and ensure safe transportation.

As shown in fig. 3, the chassis 10 may be internally recessed with a weight-reducing hole 101 for reducing the weight of the container 100. Specifically, the underframe 10 is provided with a cross beam, a longitudinal beam and the like which are arranged on the main board 1, and the weight reducing holes 101 are optionally arranged in the cross beam and the longitudinal beam.

In addition, as shown in fig. 4 and 5, the container 100 includes a telescopic arm 7, the external hanging device 50 is fixed on the telescopic arm 7, in the first state, the telescopic arm 7 is in a telescopic state, the external hanging device 50 is accommodated in the concave structure 3, in the second state, the telescopic arm 7 extends outwards, and the external hanging device 50 protrudes outwards from the concave structure 3 and protrudes transversely from the bottom side beam 2.

That is, in the present invention, the external hanging device 50 may be housed in the recess 3, or may extend laterally by the telescopic arm 7 and protrude to the outside of the bottom side member 2. The plug-in device 50 of the present invention can be placed in the recess structure 3 when not in use, or can be extended to the outside of the bottom side member 2 through the telescopic arm 7 when in use, thereby facilitating the use of the device by the user. The telescopic arm 7 may be a cylinder or the like.

In this embodiment, the external hanging device 50 is fixed to both ends of the telescopic arm 7, and the telescopic arm 7 is also parallel to the reinforcement beam 22. The telescopic arms 7 can simultaneously extend the external hanging devices 50 at the two ends outwards together when the telescopic arms extend, and similarly, the telescopic arms 7 can simultaneously move the external hanging devices 50 at the two ends inwards together and accommodate the external hanging devices 50 in the concave structure 3 when the telescopic arms are shortened.

The recess 3 is provided with at least four, and the plug-in device 50 is also provided with at least four and corresponds to the recess 3. I.e. one plug-in device 50 is associated with each of the recess structures 3. The plug-in device 50 comprises a support frame 5 and a support member 6 which can extend downwards from the support frame 5, wherein in a third state the support member 6 can extend downwards from the support frame 5 and protrude out of the bottom of the chassis 10.

In the third state, the supporting members 6 extend downward and protrude from the bottom of the bottom frame 10, and then the plurality of supporting members 6 extend downward at the same time, so that the supporting members 6 can lift the container 100, so that the bottom frame 10 of the container 100 is separated from the ground, thereby being more beneficial to the placement of the container 100 in different ground environments and being more beneficial to loading and unloading. Of course, the plug-in device 50 has a first state of being received in the recessed structure 3, a second state of extending laterally outwardly from within the recessed structure 3, and a third state of further extending downwardly the support 6.

In this embodiment, the external hanging device 50 is provided with four, as shown in fig. 1, the recess structure 3 is also provided with four, two of which are disposed at the middle of the container 100 in the length direction near the front wall, and the other two are disposed at the rear wall. Thus, when the supporting members 6 extend downward, the four supporting members 6 are stressed together, so that the container 100 can be stably lifted.

The plug-in device 50 also includes a controller to control the extension of the support member 6. If the ground surface on which the container 100 is placed is a plane, the four supporting pieces 6 can be controlled to extend by the same length, so that the container 100 can be lifted integrally, and if the ground surface on which the container 100 is placed is not a plane, the extending length of the four supporting pieces 6 can be judged according to a leveling device on the container 100, so that the container 100 can be in a horizontal state after the four supporting pieces 6 are extended.

In addition, as described above, the container 100 also includes the side walls 30. If the external hanging device 50 extends for a longer length in the vertical direction, the side wall 30 also needs to be recessed inwards to form a receiving portion (not shown), and the receiving portion corresponds to the recessed structure 3 in the vertical direction, and the external hanging device 50 may also be received in the receiving portion. As shown in fig. 5, the external hanging device 50 includes the supporting member 6, and the supporting member 6 is accommodated in the supporting frame 5 in the first state, so that the supporting frame 5 has a longer length in the vertical direction. In the present invention, the side wall 30 is also recessed to form the receiving portion for receiving the support frame 5.

In the above description, the present invention describes the case where the external hanging device 50 is the supporting frame 5 and the supporting member 6, however, the purpose of the present invention may be achieved if the external hanging device 50 is other devices, such as a lifting device, an air conditioning cabinet, etc.

In summary, the present invention provides a container 100 having an external hanging device 50, wherein by providing a recess structure 3 on a bottom side member 2, the external hanging device 50 can be accommodated in the recess structure 3 without protruding the outer edge of the bottom side member 2. The container 100, as a whole, even if fitted with the plug-in device 50, is unchanged in size as a whole, so that standard sizes can still be met. During the transportation and assembly of the container 100, the plug-in device 50 will not affect the container 100, and the production and transportation efficiency can be greatly improved.

Furthermore, the present invention provides two embodiments of specific structures of the recess structure 3, which can adapt to the sizes of different external devices 50. The invention also provides specific structures of the reinforcing piece 21 and the reinforcing beam 22, and the reinforcing piece 21 and the reinforcing beam 22 can still ensure larger structural strength and stability under the condition that the bottom side beam 2 is provided with the concave structure 3, thereby ensuring the basic cargo carrying and transportation functions of the container 100.

In addition, the external hanging device 50 in the invention is specifically a supporting frame 5 and a supporting piece 6 which can extend downwards along the supporting frame 5, and the supporting piece 6 can extend downwards to lift the container 100, so that the container 100 is placed on the ground which is not horizontal enough, loading and unloading are facilitated, and the transportation efficiency is improved.
