Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem that existing diagonal fittings only have lifting holes with limited functionality, this invention provides a corner connector and a modular container that allows for the connection of lifting rings and hooks, thereby enhancing the adaptability of the modular container.

[0021] It should be noted that the corner connector described in this utility model is used in, but not limited to, shelters, etc. For ease of explanation, this utility model only uses the application of the corner connector in shelters as an example. The principle of the corner connector in other types of equipment is essentially the same as that in shelters, and will not be described in detail here.

[0022] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the corner connector provided in one embodiment of the present invention. Figure 2 This is an exploded view of a corner connector according to an embodiment of the present invention. The corner connector includes a connecting block 1, a first connecting member 2, and a second connecting member 3. The connecting block 1 is provided with a fixing hole 1a and a slot 1b arranged in a cross configuration. The first connecting member 2 includes a plug-in part 21 and a fixing part 22 connected to each other. The plug-in part 21 is inserted into the fixing hole 1a, and the fixing part 22 is configured to limit the insertion depth of the plug-in part 21 and is provided with a threaded interface 22a. The second connecting member 3 includes a connecting part 31 and a limiting part 32 connected to each other. The connecting part 31 is inserted into the slot 1b and is detachably connected to the plug-in part 21. The limiting part 32 is configured to limit the insertion depth of the connecting part 31 and is provided with a threaded interface 22a.

[0023] Specifically, during assembly, the plug-in part 21 and the connecting part 31 are respectively inserted into the fixing hole 1a and the slot 1b, and then the connecting part 31 is detachably connected to the plug-in part 21. At this time, the plug-in part 21 and the connecting part 31 are restricted by the fixing part 22 and the limiting part 32, respectively, to prevent the plug-in part 21 and the connecting part 31 from extending into the connecting block 1. The connection between the plug-in part 21 and the connecting part 31 can restrict the plug-in part 21 and the connecting part 31 from detaching from the connecting block 1. By providing a threaded interface 22a in the fixing part 22 and the limiting part 32, the threaded interface 22a allows for the connection of structures such as lifting rings and hooks, enhancing the adaptability of the container and making it suitable for connections between containers, container fixation, and other soft and hard connections that need to be anchored on the corner fittings of the container.

[0024] It should be understood that the insertion part 21 and the connecting part 31 can be connected by threads, snap-fit, etc., specifically, such as Figure 2 As shown, in one embodiment, the insertion part 21 has a threaded through hole 21a along the axial direction of the slot 1b; the connecting part 31 is threadedly connected to the threaded through hole 21a.

[0025] When it is necessary to connect the plug part 21 and the connecting part 31, the connecting part 31 is inserted into the threaded through hole 21a and the connecting part 31 is threadedly connected to the threaded through hole 21a, thus realizing the connection between the connecting part 31 and the plug part 21.

[0026] To facilitate the hoisting of the modular housing, therefore, such as Figure 2 , 3 As shown in Figure 4, in one embodiment, the corner connector further includes a lifting eye member 4, which includes a lifting eye 41 and a stud 42. The stud 42 is connected to the lifting eye 41 and is threadedly connected to the threaded interface 22a.

[0027] In this embodiment, the lifting ring 41 is threadedly connected to the threaded interface 22a via the stud 42, thereby connecting the lifting ring 41 to the connecting block 1, so that the lifting equipment can lift the container via the lifting ring 41.

[0028] In order to restrict the position of the insertion part 21 and the connecting part 31, for this purpose, such as Figure 1 and Figure 2 As shown, in one embodiment, the cross-section of the inner wall of the fixing hole 1a is oval; the cross-section of the insertion part 21 is formed to match the cross-sectional shape of the fixing hole 1a.

[0029] In this embodiment, by matching the cross-sectional shape of the plug-in part 21 with that of the fixing hole 1a, and the inner wall cross-section of the fixing hole 1a being oval, the plug-in part 21 can be restricted from moving radially along the fixing hole 1a and rotating relative to the fixing hole 1a. The matching of the plug-in part 21 with the fixing hole 1a can limit the position of the connecting part 31 connected to the plug-in part 21.

[0030] Since the insertion part 21 is fixed in the radial position along the fixing hole 1a, if the insertion position of the connecting part 31 is fixed, it will be difficult for the connecting part 31 to be threadedly connected to the insertion part 21. Therefore, if Figure 2 and Figure 5 As shown, in one embodiment, the slot 1b is elongated and its orientation is perpendicular to the axis of the fixing hole 1a; the connecting part 31 is slidably inserted into the slot 1b along the length of the slot 1b.

[0031] In this embodiment, by setting the slot 1b into a long strip shape and setting the slot 1b along the direction of the axis perpendicular to the fixing hole 1a, the insertion part 21 can move within the slot 1b along the length direction of the slot 1b, so that the insertion part 21 can move to align with the threaded through hole 21a, which facilitates threaded connection with the threaded through hole 21a.

[0032] To facilitate observation of the alignment of the threaded connection between the insertion part 21 and the connecting part 31, therefore, as follows: Figure 5 As shown, in one embodiment, the interior of the connecting block 1 is hollow, and a window 1c communicating with the interior of the connecting block 1 is also provided.

[0033] In this embodiment, by setting window 1c, the operator can observe the alignment of the connecting part 31 and the threaded through hole 21a within the connecting block 1. The connecting part 31 is threadedly connected to the insertion part 21. To ensure sufficient preload between the connecting part 31 and the insertion part 21, and to facilitate rotation of the connecting part 31, for the following reasons: Figure 2 and Figure 3 As shown, in one embodiment, the cross-section of the limiting portion 32 is a regular hexagon.

[0034] In this embodiment, by setting the cross section of the limiting part 32 to a regular hexagon, the limiting part 32 can be rotated by tools such as a wrench, so that the limiting part 32 drives the connecting part 31 to rotate, so that when the connecting part 31 is threadedly connected to the insertion part 21, sufficient preload can be formed, and the connecting part 31 can be rotated easily.

[0035] To limit the depth of the threaded connection between the connecting part 31 and the insertion part 21, therefore, as follows: Figure 2 and Figure 3 As shown, in one embodiment, the connecting portion 31 is in the shape of a stepped column, and the small diameter section of the connecting portion 31 is threadedly connected to the threaded through hole 21a.

[0036] By setting the connecting part 31 in a stepped shape, after the small diameter section of the connecting part 31 is threadedly connected to the threaded through hole 21a, the threaded connection depth of the connecting part 31 can be limited when the large diameter section of the connecting part 31 abuts against the insertion part 21.

[0037] When the lifting ring 41 is threaded through the stud 42 and the threaded interface 22a, after the connection between the stud 42 and the threaded interface 22a reaches the set preload, the lifting ring 41 is fixed at the set angle. When the hook is passed through the lifting ring 41, if the angle at which the lifting ring 41 is fixed is not appropriate, the lifting ring 41 may rotate during the lifting process, causing the connection between the stud 42 and the threaded interface to loosen. Therefore, if... Figure 2 and Figure 4 As shown, in one embodiment, the stud 42 includes a first stud 421, a second stud 422, and a third stud 423 that are connected sequentially and coaxially. The outer wall of the first stud 421 is provided with an external thread and is threadedly connected to the threaded interface 22a. The outer diameters of the first stud 421, the second stud 422, and the third stud 423 increase sequentially. The lifting ring 4 also includes a sleeve 43, a retaining ring 44, and a blocking part 45. The sleeve 43 is rotatably fitted onto the third stud 423. The outer wall cross-section of the sleeve 43 is regular hexagonal. The retaining ring 44 is rotatably fitted onto the second stud 422 and connected to one end of the sleeve 43. The inner diameter of the retaining ring 44 is smaller than the outer diameter of the third stud 423. The lifting ring 41 is connected to the other end of the sleeve 43, and the blocking part 45 is connected to the sleeve 43. It has a connected state connected to the third stud 423 and a disengaged state disconnected from the third stud 423.

[0038] In this embodiment, when it is necessary to connect the stud 42 to the threaded interface 22a, the sleeve 43 is fitted onto the third column 423 via the first column 421 and the second column 422. Then, the blocking part 45 is connected to the third column 423, so that the blocking part 45 is in the connected state. Then, the lifting ring 41 is rotated. At this time, the lifting ring 41 can drive the third column 423, the second column 422, and the first column 421 to rotate via the sleeve 43 and the blocking part 45, so that the first column 421 connects to the threaded interface 22a. When the fixed angle of the lifting ring 41 needs to be adjusted, the blocking part 45 is disengaged from the third column 423. At this time, the sleeve 43 can rotate relative to the third column 423, so that the lifting ring 41 can rotate relative to the sleeve 43. Moreover, since the outer diameters of the first column 421, the second column 422 and the third column 423 increase sequentially, when the second column 422 abuts against the limiting part 32 or the fixing part 22, the sleeve 43 can still rotate relative to the second column 422 and the third column 423.

[0039] It should be understood that the blocking part 45 and the sleeve 43 can be threaded or slidably connected. When the blocking part 45 is a screw, the third column 423 has a through hole, and the blocking part 45 is inserted into the through hole to achieve the connection and disengagement of the blocking part 45 and the third column 423. The blocking part 45 can also be a slider, which is slidably inserted into the sleeve 43 and into the through hole to achieve the connection and disengagement of the blocking part 45 and the third column 423. Figure 4 As shown, in one embodiment, the third column 423 has a through hole, the blocking part 45 is a screw, the screw is threadedly connected to the sleeve 43 and can be inserted into or removed from the through hole.

[0040] When it is necessary to connect the blocking part 45 with the third column 423, the blocking part 45 is rotated so that the blocking part 45 enters the through hole. At this time, the lifting ring 41 can drive the third column 423 to rotate through the sleeve 43 and the blocking part 45. When it is necessary to rotate the lifting ring 41, the blocking part 45 is controlled to disengage from the third column 423. At this time, the sleeve 43 can rotate relative to the third column 423.

[0041] like Figure 6 As shown, in a second aspect, the present invention also provides a container, including the aforementioned corner connector.

[0042] The modular shelter is formed by splicing profile 5 and corner connectors. The profile 5 and the connecting block 1 of the corner connector can be connected by welding or other methods.
