Description

Technical Field

[0001] The present invention relates to the technical field of connecting devices, and particularly to a connecting structure and a container. Background Art

[0002] Containers can be used as carriers for transporting goods or as spaces for living, working, cultural activity rooms, etc. Containers often need to be externally lifted, the box bodies spliced, or externally extended and built. Currently, containers are generally fixedly connected at the corner fittings by means of twist locks or bridge locks. If non-standard customized expansion is to be carried out outside the box body, connection needs to be made by means of welding, etc. This not only destroys the integrity of the box body but also is not conducive to disassembly and secondary assembly. Summary of the Invention

[0003] Based on this, the present invention aims to overcome the problems existing in the need for welding and other treatments on the box body in the existing connection method and the inconvenience of disassembly, and provides a connecting structure and a container that do not require welding and are convenient for disassembly and assembly.

[0004] The technical solution is as follows:

[0005] A connecting structure, comprising:

[0006] Snap members, there are at least two snap members, each snap member includes a connected first buckle body part and a penetrating part, the first buckle body part is bent or protruded toward one side of the penetrating part, and different snap members are used to respectively penetrate the assembly holes of the to-be-connected members, so that part of the penetrating part is located on the side of the to-be-connected member away from the first buckle body part; and

[0007] Lap members, the lap members are detachably connected to all the snap members respectively;

[0008] Wherein, when the lap members are connected to all the snap members, all the first buckle body parts extend in a direction away from each other and form a first limiting group, and the first limiting group is used to prevent the snap members from detaching from the assembly holes along the direction from the first buckle body part to the penetrating part.

[0009] For the above connecting structure, at least two snap members can be passed through the assembly holes of the to-be-connected members, so that part of the penetrating part is located on the side of the to-be-connected member away from the first buckle body part, and then the lap members are detachably connected to all the snap members. The first buckle part is bent or protruded toward one side of the penetrating part. Then, when the lap members are connected to all the snap members, all the first buckle body parts extend in a direction away from each other and form a first limiting group, which can prevent the snap members from detaching from the assembly holes along the direction from the first buckle body to the penetrating part. At this time, one end of the snap member located on the side of the to-be-connected member away from the first buckle body can be used to connect to an external structure, without welding and other treatments, without destroying the integrity of the to-be-connected member, and can be completely disassembled when not needed, making disassembly and assembly more convenient.

[0010] In one embodiment, the overlapping member includes an insertion body. When all the passing portions pass through the assembly holes, the passing portions are in clearance fit with the assembly holes. The insertion body is used to be inserted into the gap between different snap members, so that at least part of the first buckle body portions are separated from each other. When the insertion body is inserted into the gap between different snap members, the first limiting group is used to prevent the snap members from detaching from the assembly holes along the direction from the first buckle body portion to the passing portion.

[0011] In one embodiment, the snap member further includes a second buckle body portion. The second buckle body portion is arranged on the side of the passing portion away from the first buckle body portion. The second buckle body portion and the first buckle body portion are bent or protruded toward the same side of the passing portion. When the insertion body is inserted into the gap between different snap members, at least part of the second buckle body portions are separated from each other. All the second buckle body portions form a second limiting group;

[0012] Wherein, the first limiting group and the second limiting group are used to prevent the snap members from detaching from the assembly holes;

[0013] Or the overlapping member and the first limiting group are respectively located on both sides of the to-be-connected member. The first limiting group and the overlapping member are used to prevent the snap members from detaching from the assembly holes.

[0014] In one embodiment, the overlapping member further includes a limiting body connected to the insertion body. An insertion opening is formed between the limiting body and the insertion body. When the insertion body is inserted into the gap between different snap members, the overlapping member and the first limiting group are respectively located on both sides of the to-be-connected member. The passing portion is inserted into the insertion opening, so that the first limiting group and the overlapping member are used to prevent the snap members from detaching from the assembly holes.

[0015] In one embodiment, the limiting body is detachably connected to the second buckle body portion or the passing portion.

[0016] In one embodiment, the above connection structure further includes a fastener. A first fixing hole is provided on the second buckle body portion, and a second fixing hole is provided on the limiting body. The fastener passes through the first fixing hole and is in threaded fit with the second fixing hole, so that the second buckle body portion is connected to the limiting body.

[0017] In one embodiment, the overlapping member further includes an external connection body. The external connection body is connected to the insertion body and the limiting body at an angle. When the insertion body is inserted into the gap between different snap members, the external connection body extends out of the second buckle body portion along the direction from the passing portion to the second buckle body portion.

[0018] In one embodiment, there are two snap members, namely a first snap member and a second snap member respectively. There are two limiting bodies, which are respectively located on both sides of the plug-in body. When the penetrating parts of the first snap member and the second snap member penetrate the assembly hole, the plug-in body is inserted into the gap between the first snap member and the second snap member, so that the penetrating parts of the first snap member and the second snap member are respectively in contact with the inner wall of the assembly hole.

[0019] In one embodiment, the sides of the penetrating part respectively have a first side and a second side. The first buckle body part and the second buckle body part are bent or protruded along the direction from the first side to the second side. The second side includes a first arc surface, a plane and a second arc surface arranged in sequence along the circumferential direction. The first arc surface and the second arc surface are respectively connected to both sides of the first side. The plug-in body is used to be inserted into the gap between the first side of the first snap member and the first side of the second snap member, so that the second side of the first snap member and the second side of the second snap member are respectively in contact with the inner wall of the assembly hole.

[0020] In one embodiment, the thickness of the end of the plug-in body gradually decreases along the direction of inserting into the gap between different snap members.

[0021] In one embodiment, one of the snap members is a third snap member, and the remaining snap members are assembled components. When the penetrating parts of the assembled components penetrate the assembly hole, the first buckle body part and the penetrating part of the third snap member can penetrate the assembly hole.

[0022] A container includes a to-be-connected member and the connection structure as described in any one of the above. The to-be-connected member is a box body structure, and the box body structure is provided with assembly holes. Different snap members are used to respectively penetrate the assembly holes, so that part of the penetrating parts are located outside the box body structure. When the overlapping member is connected to all the snap members, the first limiting group is used to prevent the snap members from disengaging from the assembly holes along the direction from the first buckle body part to the penetrating part.

[0023] For the above-mentioned container, at least two snap members can be successively inserted through the assembly holes of the box structure, such that the inserted part is partially located on the side of the connection member away from the first buckle part. Then, the overlapping member is detachably connected to all the snap members, and the first buckle part is bent or protruded towards the inserted part. When the overlapping member is connected to all the snap members, all the first buckle parts extend in directions away from each other and form a first limiting group, which can prevent the snap members from disengaging from the assembly holes along the direction from the first buckle part to the inserted part. At this time, one end of the snap member located on the side of the connection member away from the first buckle part can be used to connect to an external structure, without the need for processing such as welding, which will not damage the integrity of the box structure, and can be completely disassembled when not in use, making disassembly and assembly more convenient.

[0024] In one embodiment, the box structure includes a main box body and corner fittings. The main box body is connected to the corner fittings, and the assembly holes are provided on the corner fittings. When the overlapping member is connected to all the snap members, the first limiting group is located inside the corner fittings. Brief Description of the Drawings

Detailed implementation manners

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] As Figure 1 and Figure 2 shown, an embodiment discloses a connection structure, including a fastener 100 and a lapping part 200. There are at least two fasteners 100. The fastener 100 includes a connected first buckle body part 110 and a penetrating part 120. The first buckle body part 110 bends or protrudes toward the side of the penetrating part 120. Different fasteners 100 are used to respectively penetrate the assembly holes 10a of the to-be-connected part 10, so that part of the penetrating part 120 is located on the side of the to-be-connected part 10 away from the first buckle body part 110. Among them, when the lapping part 200 is connected to all the fasteners 100, all the first buckle body parts 110 extend in a direction away from each other and form a first limiting group, and the first limiting group is used to prevent the fastener 100 from disengaging from the assembly hole 10a along the direction from the first buckle body part 110 to the penetrating part 120.

[0035] For the above connection structure, at least two snap members 100 can be passed through the assembly holes 10a of the member to be connected 10, so that the passing part 120 is partially located on the side of the member to be connected 10 away from the first buckle part 110. Then, the overlapping member 200 is detachably connected to all the snap members 100, and the first buckle part is bent or protruded toward the passing part 120. When the overlapping member 200 is connected to all the snap members 100, all the first buckle parts 110 extend in a direction away from each other and form a first limiting group, which can prevent the snap members 100 from disengaging from the assembly holes 10a along the direction from the first buckle body to the passing part 120. At this time, one end of the snap member 100 located on the side of the member to be connected 10 away from the first buckle body can be used to connect to an external structure without processes such as welding, which will not damage the integrity of the member to be connected 10, and can be completely removed when not needed, making disassembly and assembly more convenient.

[0036] Among them, after all the first buckle parts 110 pass through the assembly holes 10a, the overlapping member 200 is connected to all the snap members 100. At this time, all the first buckle parts 110 are located inside the member to be connected 10, so the first limiting group formed by all the first buckle parts 110 is also located inside the member to be connected 10. At the same time, the passing part 120 passes through the assembly holes 10a and partially extends out of the assembly holes 10a along the direction away from the first buckle part 110, so that the passing part 120 is at least partially located outside the member to be connected 10 and can be used to connect to an external structure.

[0037] Among them, when the snap member 100 passes through the assembly hole 10a of the member to be connected 10, the first buckle part 110 can pass through the assembly hole 10a; or the passing part 120 can pass through the assembly hole 10a. No matter which of the above methods is adopted, after the snap member 100 passes through the assembly hole 10a, the passing part 120 will occupy a certain space in the assembly hole 10a. Therefore, it is necessary to ensure that after the existing snap members 100 pass through the assembly hole 10a, the subsequent snap members 100 can still pass through the assembly hole 10a.

[0038] In one embodiment, such as Figure 1 and Figure 2As shown, the overlapping member 200 includes an insertion body 210. When all the passing portions 120 pass through the assembly holes 10a, the passing portions 120 are in clearance fit with the assembly holes 10a. The insertion body 210 is used to be inserted into the gap between different buckle members 100, so that at least part of the first buckle body portions 110 are separated from each other. When the insertion body 210 is inserted into the gap between different buckle members 100, the first limiting group is used to prevent the buckle members 100 from disengaging from the assembly holes 10a in the direction from the first buckle body portion 110 to the passing portion 120. When all the buckle members 100 partially pass through the assembly holes 10a and the passing portions 120 pass through the assembly holes 10a, the insertion body 210 can be inserted into the gaps between different buckle members 100, so that the first buckle body portions 110 of the buckle members 100 are separated from each other. At this time, the first limiting group formed by the first buckle body portions 110 is enlarged compared with before the insertion body 210 is inserted, which can better prevent the buckle members 100 from disengaging from the assembly holes 10a in the direction from the first buckle body to the passing portion 120. The insertion and connection method between the insertion body 210 and the buckle members 100 is simple to assemble and disassemble, and has a better fixing and limiting effect on the buckle members 100. In addition, by inserting the insertion body 210 into the gaps between different buckle members 100, the gap between the buckle members 100 and the inner wall of the assembly holes 10a can be reduced, the movement of the buckle members 100 in the assembly holes 10a can be reduced, and the buckle members 100 can be set more stably.

[0039] Optionally, when the insertion body 210 is inserted into the gap between different buckle members 100, the passing portion 120 contacts the inner wall of the assembly hole 10a. At this time, the passing portion 120 will not displace, and the buckle members 100 can be stably set.

[0040] In other embodiments, the first buckle body portion 110 and the passing portion 120 of the buckle member 100 are connected in an L shape. At this time, both the first buckle body portion 110 and the passing portion 120 can pass through the assembly hole 10a. When the overlapping member 200 is connected to all the buckle members 100, the passing portions 120 of different buckle members 100 pass through the assembly hole 10a in the same direction, and the first buckle body portions 110 of different buckle members 100 are arranged at an angle, so that the first limiting group forms a structure similar to a multi-claw anchor. At this time, the first limiting group can also prevent the buckle members 100 from disengaging from the assembly holes 10a. Optionally, when the passing portions 120 of all the buckle members 100 pass through the assembly holes 10a, all the buckle members 100 contact each other in the assembly holes 10a and respectively contact the inner wall of the assembly holes 10a. At this time, there is no gap between the buckle members 100.

[0041] In one embodiment, as Figure 1 and Figure 2As shown, the buckle member 100 further includes a second buckle body portion 130. The second buckle body portion 130 is disposed on a side of the penetrating portion 120 away from the first buckle body portion 110. The second buckle body portion 130 and the first buckle body portion 110 are bent or protruded toward the same side of the penetrating portion 120. When the plug-in body 210 is inserted into the gap between different buckle members 100, at least part of the second buckle body portions 130 move away from each other, and all the second buckle body portions 130 form a second limiting group; wherein, the first limiting group and the second limiting group are used to prevent the buckle member 100 from detaching from the assembly hole 10a; or the overlapping member 200 and the first limiting group are respectively located on both sides of the to-be-connected member 10, and the first limiting group and the overlapping member 200 are used to prevent the buckle member 100 from detaching from the assembly hole 10a. At this time, the limiting principle of the second buckle body portion 130 and the first buckle body portion 110 is similar. By inserting the plug-in body 210 into the gap between different buckle members 100, the second buckle body portions 130 of different buckle members 100 move away from each other, and the second limiting group formed by the second buckle body portions 130 expands compared with before the plug-in body 210 is inserted. Then, the buckle member 100 can be limited by the first limiting group and the second limiting group, or the overlapping member 200 is arranged on a side of the to-be-connected member 10 away from the first limiting group, and the overlapping member 200 and the first limiting group are used to limit the buckle member 100. The buckle member 100 cannot detach from the assembly hole 10a whether in the direction from the first limiting group to the second limiting group or in the reverse direction, and the limiting effect on the buckle member 100 is better.

[0042] Wherein, one of the first buckle body portions 110 and the second buckle body portions 130 of different buckle members 100 can pass through the assembly hole 10a in sequence or simultaneously, and then the overlapping member 200 is inserted into the gap between different buckle members 100, so that the first limiting group and the second limiting group can prevent the buckle member 100 from detaching from the assembly hole 10a.

[0043] In other embodiments, the buckle member 100 only includes the first buckle body portion 110 and the penetrating portion 120, and the first buckle body portion 110 and the penetrating portion 120 are connected in an L shape. At this time, the overlapping member 200 is disposed on a side of the to-be-connected member 10 away from the first buckle body portion 110. After the overlapping member 200 is connected to the buckle member 100, the overlapping member 200 and the first limiting group are used to prevent the buckle member 100 from detaching from the assembly hole 10a, and the buckle member 100 can also be limited.

[0044] In one embodiment, as Figure 1 and Figure 2As shown, the overlapping member 200 further includes a limiting member 220 connected to the plug-in member 210. A socket 201 is formed between the limiting member 220 and the plug-in member 210. When the plug-in member 210 is inserted into the gap between different buckle members 100, the overlapping member 200 and the first limiting group are respectively located on both sides of the to-be-connected member 10. The penetrating portion 120 is inserted into the socket 201, so that the first limiting group and the overlapping member 200 are used to prevent the buckle member 100 from detaching from the assembly hole 10a. The socket 201 can make the cooperation between the overlapping member 200 and the buckle member 100 more stable, and prevent relative displacement between different buckle members 100. It can enable all the buckle members 100 and the overlapping member 200 to continuously prevent the buckle member 100 from detaching from the assembly hole 10a after connection, and be more stable when connecting to an external structure. At the same time, the overlapping member 200 can fill the gap between the first limiting group and the second limiting group, so that the first limiting group can tightly press against the to-be-connected member 10, then the buckle member 100 will not displace after being connected to the overlapping member 200, and can better prevent the buckle member 100 from detaching from the assembly hole 10a.

[0045] Specifically, the first buckle body portion 110 is located inside the to-be-connected member 10, and the overlapping member 200 and the second buckle body portion 130 are located outside the to-be-connected member 10. After the first buckle body portion 110 extends into the to-be-connected member 10, only by cooperating the overlapping member 200 with the buckle member 100 outside the to-be-connected member 10 can the fixation of the buckle member 100 be achieved, and the operation is simpler.

[0046] In one embodiment, the limiting member 220 is detachably connected to the second buckle body portion 130 or the penetrating portion 120. At this time, the limiting member 220 can be further connected to the buckle member 100 to prevent the limiting member 220 from detaching from the buckle body.

[0047] In one embodiment, as Figure 1 and Figure 2 shown, the above connection structure further includes a fastener 300. A first fixing hole 131 is provided on the second buckle body portion 130, and a second fixing hole 221 is provided on the limiting member 220. The fastener 300 penetrates through the first fixing hole 131 and is threadedly engaged with the second fixing hole 221, so that the second buckle body portion 130 is connected to the limiting member 220. Since the limiting member 220 is located between the first buckle body portion 110 and the second buckle body portion 130, when connecting the limiting member 220 to the second buckle body portion 130, the fastener 300 can penetrate through the first fixing hole 131 from the side of the second buckle body portion 130 far from the limiting member 220 and be threadedly engaged with the second fixing hole 221 on the limiting member 220. At this time, the installation and disassembly between the overlapping member 200 and the buckle member 100 are more convenient.

[0048] Among them, the fastener 300 can be a screw or a bolt.

[0049] In other embodiments, the overlapping member 200 can also be a bolt. By passing the bolt through different buckle members 100 respectively and threadedly mating with the buckle members 100, the detachable connection and cooperation between the overlapping member 200 and different buckle members 100 are realized.

[0050] In one embodiment, as Figure 1 and Figure 2 shown, the overlapping member 200 further includes an external connection body 230. The external connection body 230 is angularly connected to the insertion body 210 and the limiting body 220. When the insertion body 210 is inserted into the gap between different buckle members 100, the external connection body 230 extends out of the second buckle body portion 130 along the direction from the insertion portion 120 to the second buckle body portion 130. The external connection portion can be used to connect to an external structure. At this time, if the insertion portion 120 is arranged horizontally, through the connection between the limiting body 220 and the second buckle body portion 130, and the limiting body 220 is located between the to-be-connected member 10 and the second buckle body portion 130, the external connection portion can bear both transverse loads and vertical loads simultaneously, and can meet different requirements for connecting to an external structure.

[0051] Optionally, through holes 231 or columns are provided on the external connection body 230 for connecting to an external structure.

[0052] In one embodiment, as Figure 1 and Figure 2 shown, there are two buckle members 100, which are the first buckle member 100a and the second buckle member 100b respectively. There are two limiting bodies 220, which are respectively located on both sides of the insertion body 210. When the insertion portions 120 of the first buckle member 100a and the second buckle member 100b pass through the assembly hole 10a, the insertion body 210 is inserted into the gap between the first buckle member 100a and the second buckle member 100b, so that the insertion portions 120 of the first buckle member 100a and the second buckle member 100b are respectively in contact with the inner wall of the assembly hole 10a. When the insertion body 210 is inserted into the gap between the first buckle member 100a and the second buckle member 100b, the first buckle member 100a and the second buckle member 100b can be squeezed away from each other, so that the insertion portions 120 of the first buckle member 100a and the second buckle member 100b are respectively in contact with the inner wall of the assembly hole 10a. At this time, the first buckle body portion 110 will extend beyond the range where the assembly hole 10a is located on the to-be-connected member 10, which can prevent the buckle member 100 from detaching from the assembly hole 10a along the direction from the first buckle body portion 110 to the second buckle body portion 130. Similarly, the second buckle body portion 130 or the overlapping member 200 can prevent the buckle member 100 from detaching from the assembly hole 10a along the direction from the second buckle body portion 130 to the first buckle body portion 110, and can make the buckle member 100 installed stably without displacement.

[0053] In other embodiments, the number of the buckle members 100 may also be at least three. At this time, the arrangement of the buckle members 100 may still be arranged in sequence along a direction. At this time, the number of the insertion members 210 is one less than the number of the buckle members 100. Different insertion members 210 are arranged in parallel at intervals and can be respectively inserted into the gaps between two adjacent buckle members 100.

[0054] Or the buckle members 100 are arranged along the circumferential direction of the assembly hole 10a. One ends of all the insertion members 210 are connected, and an included angle is formed between two adjacent insertion members 210. The insertion members 210 are used for being inserted into the gaps between two adjacent buckle members 100.

[0055] In one embodiment, as Figures 1 to 3 shown, the side surfaces of the penetrating portion 120 respectively have a first side surface and a second side surface 121. The first buckle body portion 110 and the second buckle body portion 130 are bent or protruded along the direction from the first side surface to the second side surface 121. The second side surface 121 includes a first arc surface 121a, a plane 121b and a second arc surface 121c which are arranged in sequence along the circumferential direction. The first arc surface 121a and the second arc surface 121c are respectively connected to the two side edges of the first side surface. The insertion member 210 is used for being inserted into the gap between the first side surface of the first buckle member 100a and the first side surface of the second buckle member 100b, so that the second side surface 121 of the first buckle member 100a and the second side surface 121 of the second buckle member 100b are respectively abutted against the inner wall of the assembly hole 10a. When the assembly hole 10a is an oblong hole, the second side surface 121 of the penetrating portion 120 can be matched with the inner wall of the assembly hole 10a, and the penetrating portion 120 will not rotate in the assembly hole 10a after being matched with the overlapping member 200, realizing circumferential fixation.

[0056] In one embodiment, as Figure 1 and Figure 2 shown, the thickness of the end portion of the insertion member 210 gradually decreases along the direction of inserting into the gaps between different buckle members 100. At this time, it is convenient for the insertion member 210 to be inserted into the gap.

[0057] In one embodiment, one of the buckle members 100 is a third buckle member, and the remaining buckle members 100 are assembled components. When the penetrating portion 120 of the assembled component penetrates through the assembly hole 10a, the first buckle body portion 110 and the penetrating portion 120 of the third buckle member can penetrate through the assembly hole 10a. At this time, it can be ensured that all the buckle members 100 can penetrate through the assembly hole 10a, preventing the situation of impossible installation.

[0058] Optionally, when the buckle 100 passes through the assembly hole 10a and different buckles 100 come into contact, the shape of the first limiting group matches the shape of the assembly hole 10a, and the size of the first limiting group can pass through the assembly hole 10a. Then, when the penetrating portion 120 is located within the assembly hole 10a, the penetrating portion 120 has a clearance fit with the assembly hole 10a. By inserting the plug-in body 210 into the gap between different buckles 100, the first limiting group can be expanded, and thus it will not pass through the assembly hole 10a again in the direction from the first buckle body portion 110 to the penetrating portion 120.

[0059] As Figure 1 , Figure 2 and Figure 4 shown, an embodiment discloses a container, which includes a to-be-connected member 10 and a connection structure as described in any of the above embodiments. The to-be-connected member 10 is a box body structure, and an assembly hole 10a is provided on the box body structure. Different buckles 100 are respectively used to pass through the assembly hole 10a, so that the penetrating portion 120 is partially located outside the box body structure. When the overlapping member 200 is connected to all the buckles 100, the first limiting group is used to prevent the buckle 100 from disengaging from the assembly hole 10a in the direction from the first buckle body portion 110 to the penetrating portion 120.

[0060] For the above container, at least two buckles 100 can be sequentially passed through the assembly holes 10a of the box body structure, so that the penetrating portion 120 is partially located on the side of the to-be-connected member 10 away from the first buckle body portion 110. Then, the overlapping member 200 is detachably connected to all the buckles 100, and the first buckle portion is bent or protruded toward the side of the penetrating portion 120. Then, when the overlapping member 200 is connected to all the buckles 100, all the first buckle body portions 110 extend in a direction away from each other and form a first limiting group, which can prevent the buckle 100 from disengaging from the assembly hole 10a in the direction from the first buckle body to the penetrating portion 120. At this time, one end of the buckle 100 located on the side of the to-be-connected member 10 away from the first buckle body can be used to connect to an external structure, without welding or other treatments, which will not damage the integrity of the box body structure, and can be completely disassembled when not in use, making disassembly and assembly more convenient.

[0061] In one of the embodiments, as Figure 1 , Figure 2 and Figure 4 shown, the box body structure includes a main box body 11 and corner fittings 12. The main box body 11 is connected to the corner fittings 12, and the assembly hole 10a is provided on the corner fittings 12. When the overlapping member 200 is connected to all the buckles 100, the first limiting group is located within the corner fittings 12. Generally, the main box body 11 of the container uses the corner fittings 12 as the external part. The buckle 100 is used to pass through the assembly hole 10a at the corner, which will not affect the main box body 11 of the container, and there is no need to perform welding or other treatments on the corner fittings 12, making installation and disassembly convenient.
