Figure 4

[0049] It should be noted that in the embodiment, the limiting assembly is arranged at the bottom of the door structure 10, and in some embodiments, the limiting assembly can also be arranged at the top of the door structure 10 and the like, and the arrangement position is selected according to the design requirements of the container; in addition, in some embodiments, the installation positions of the rotating structure 50 and the limiting piece 20 can be interchanged, that is, the limiting piece 20 is arranged on the door frame 12, and the support 40 is arranged on the door plate 11 through the rotating structure 50.

[0050] In some embodiments, the limiting assembly can also be applied to a window structure, for example, one end of the support 40 is arranged on a window frame through the rotating structure 50, and the other end is slid to the limiting piece 20 on a window door through the connecting piece 30; when the window (window door) is opened, the opening state can be ensured to be stable through the limiting structure; not only limited to this, but also can be applied to other structures in other fields, not only limited to this, and details are not described here.

[0051] In the embodiment, when the door plate 11 is in the closed state (as shown in FIG. 5), the connecting piece 30 is clamped in the limiting groove section 212, that is, the rotation of the support 40 is limited, the door plate 11 is supported by the support 40, and the relative position between the door plate 11 and the door frame 12 is limited, that is, the door plate 11 cannot be continuously opened, and also cannot be closed; at this time, the door plate 11 is in the open state, and the door plate 11 does not need to be fixed additionally, the stability of the door plate 11 when being opened is ensured, and it is beneficial for the operator to perform relevant operations on the container. Figure 7 ​As shown in the figure, the rotating structure 50 is arranged between the connecting pieces 30 and the rotating shaft (the shaft for the door plate 11 to rotate relative to the door frame 12) of the door plate 11; in some embodiments, the connecting pieces 30 can also be arranged between the rotating structure 50 and the rotating shaft (in this state, the connecting pieces 30 can be arranged at the top of the door plate 11 to avoid the support piece 40 from being blocked at the opening of the door frame 12 when the door plate 11 is opened, thereby affecting the operation of the operator), and the installation is carried out according to the actual use, and the installation flexibility of the limiting assembly is high, and the use is convenient.

[0052] In addition, it should be noted that in the embodiment, the door plate 11 is shown in the closed state, the support piece 40 and the limiting piece 20 are arranged in an up-down staggered manner, the support piece 40 and the limiting piece 20 do not exceed the coverage range of the door frame 12, and do not occupy the space in the direction perpendicular to the door plate 11, thereby effectively improving the space utilization rate of the container.

[0053] Figure 5 Figure 7 Figure 8 In addition, it should be noted that in the embodiment, the door plate 11 is shown in the closed state, the support piece 40 and the limiting piece 20 are arranged in an up-down staggered manner, the support piece 40 and the limiting piece 20 do not exceed the coverage range of the door frame 12, and do not occupy the space in the direction perpendicular to the door plate 11, thereby effectively improving the space utilization rate of the container. Figures 11-13 In an embodiment, the rotating structure 50 comprises a fixed seat 51, a connecting shaft 52, and a first connecting hole 53; the fixed seat 51 is arranged on the door frame 12, and the first connecting hole 53 is arranged on the support piece 40; the connecting shaft 52 comprises a first shaft section 521 and a second shaft section 522, the diameter of the first shaft section 521 is d1 mm, the diameter of the second shaft section 522 is d2 mm, the diameter of the first connecting hole 53 is d3 mm, and d1 < d3 < d2 is satisfied; one end of the second shaft section 522 away from the first shaft section 521 is connected to the fixed seat 51, and the support piece 40 is sleeved on the first shaft section 521 through the first connecting hole 53; during the opening and closing of the door plate 11, the support piece 40 rotates around the first shaft section 521.

[0054] In the embodiment, d1 < d2, the first shaft section 521 and the second shaft section 522 are in a stepped shape, a limiting surface is formed at the connection between the first shaft section 521 and the second shaft section 522, and the diameter d3 of the first connecting hole 53 is between d1 and d2, that is, when the support piece 40 is sleeved on the first shaft section 521 through the first connecting hole 53, the limiting surface provides support for the support piece 40, and during the opening and closing of the door plate 11, the support piece 40 can rotate around the first shaft section 521, thereby being simple in structure and convenient to assemble.

[0055] In an embodiment, the rotating structure 50 further comprises a limiting screw 54 and a first threaded hole 55, the first threaded hole 55 is arranged on the end face of the first shaft section 521 away from the second shaft section 522, the size of the first shaft section 521 in the axial direction of the first shaft section 521 is greater than the size of the first connecting hole 53 in the axial direction of the first connecting hole 53, and the limiting screw 54 is screwed into the first threaded hole 55, so that the two sides of the support piece 40 in the axial direction of the first connecting hole 53 are limited between the second shaft section 522 and the limiting screw 54. ​​

[0056] In this embodiment, the limiting screw 54 and the first threaded hole 55 limit the vertical movement of the support member 40. Figure 5 The displacement on the viewing angle (the same below) makes the limit screw 54 easy to install. The dimension of the first shaft segment 521 in the axial direction of the first shaft segment 521 is the same as the vertical dimension of the first shaft segment 521. The dimension of the first connecting hole 53 in the axial direction of the first connecting hole 53 is the same as the vertical dimension of the first connecting hole 53 (the thickness of the support member 40 near the first connecting hole 53). The vertical dimension of the first shaft segment 521 is greater than the vertical dimension of the first connecting hole 53. The support member 40 will have a little vertical movement allowance, which can ensure the smooth rotation of the support member 40 (i.e., the opening and closing of the door panel 11). At the same time, the support member 40 is restricted between the second shaft segment 522 and the limit screw 54 to ensure the stability of the connection of the support member 40, thereby improving the support effect of the support member 40 on the door panel 11.

[0057] In one embodiment, the connecting shaft 52 further includes a third shaft segment 523, with the second shaft segment 522 disposed between the first shaft segment 521 and the third shaft segment 523; the third shaft segment 523 is a threaded shaft, and the connecting shaft 52 is connected to the fixed seat 51 through the third shaft segment 523.

[0058] The connecting shaft 52 and the fixed base 51 are installed by screwing the third shaft segment 523 to the fixed base 51. The threaded connection is a detachable connection, and the support member 40 rotates around the connecting shaft 52. The connecting shaft 52 is a vulnerable part, which facilitates the replacement of the connecting shaft 52 later. In some embodiments, the third shaft segment 523 can also be connected to the fixed base 51 by welding, and wear can be reduced by putting a protective sleeve on the first shaft segment 521, etc., but it is not limited to these methods.

[0059] See Figure 3 as well as Figures 14-15 In one embodiment, the connector 30 sequentially includes a first sub-part 31, a second sub-part 32, and a third sub-part 33, all with circular cross-sections. The diameter of the first sub-part 31 is d4 mm, the diameter of the second sub-part 32 is d5 mm, and the diameter of the third sub-part 33 is d6 mm. The third sub-part 33 passes through the guide groove section 211 and is connected to the support member 40. The guide groove section 211 has a groove width of h mm, and the limiting groove section 212 is a circular groove with a diameter of d7 mm, satisfying the following condition: d6 < h < d5 < d7 < d4.

[0060] In this embodiment, the connecting piece 30 is stepped, when the third sub-portion 33 is connected with the support piece 40 through the guide groove segment 211, the limiting piece 20 is limited between the second sub-portion 32 and the connecting piece 30, and d6 < h, the third sub-portion 33 can freely slide in the guide groove segment 211, ensuring the smooth sliding of the connecting piece 30; when the third sub-portion 33 slides to the limiting groove segment 212, the second sub-portion 32 falls into the limiting groove segment 212 under the action of gravity, realizing the limitation of the position of the connecting piece 30, and at the same time, since the diameter of the first sub-portion 31 is greater than the diameter of the limiting groove segment 212 (d7 < d4), the connecting piece 30 cannot fall off from the limiting groove segment 212, ensuring the reliability of the connection of the components.

[0061] In actual use, when the door plate 11 is opened, the third sub-portion 33 slides from the guide groove segment 211 towards the limiting groove segment 212 until the second sub-portion 32 is clamped in the limiting groove segment 212, and the door plate 11 is in the open state, when it is needed to close the door plate 11, the connecting piece 30 is lifted, the limiting state of the second sub-portion 32 and the limiting groove segment 212 is released, and the third sub-portion 33 slides away from the limiting groove segment 212 in the guide groove segment 211 until the closing operation of the door plate 11 is completed, the structure is simple, and the installation and use are convenient.

[0062] It should be noted that in some embodiments, the cross sections of the first sub-portion 31, the second sub-portion 32 and the third sub-portion 33 can also be other shapes, for example, rectangular, which can ensure the smooth sliding of the third sub-portion 33 in the guide groove segment 211 and the stable clamping of the second sub-portion 32 in the limiting groove segment 212; in some embodiments, the connecting piece 30 can also be rotatably arranged relative to the support piece 40, that is, the connecting piece 30 is rotatably arranged at the end of the support piece 40, when the connecting piece 30 slides in the guide groove segment 211, the connecting piece 30 and the groove wall of the guide groove segment 211 are in rolling friction, which reduces the wear between the connecting piece 30 and the groove wall of the guide groove segment 211, improves the service life, and ensures the smooth sliding of the connecting piece 30 in the guide groove segment 211.

[0063] Referring to Figure 6 and Figure 14 In an embodiment, the connecting piece 30 further comprises a fourth sub-portion 34 with a circular cross section, the third sub-portion 33 is arranged between the second sub-portion 32 and the fourth sub-portion 34; the diameter of the fourth sub-portion 34 is d8 mm, and d8 > d7 is satisfied; the fourth sub-portion 34 is arranged between the support piece 40 and the limiting piece 20.

[0064] The fourth sub-portion 34 is arranged between the support piece 40 and the limiting piece 20, when the third sub-portion 33 slides in the guide groove segment 211, the fourth sub-portion 34 can separate the support piece 40 and the limiting piece 20, avoiding the frictional damage of the relative surfaces of the support piece 40 and the limiting piece 20, and improving the service life of the two.

[0065] In addition, d8>d7, when the limiting state of the second sub-portion 32 and the limiting groove segment 212 is released (the connecting piece 30 is lifted upward), the connecting piece 30 is prevented from being pulled out upward from the limiting groove segment 212, and the stability of the connection between the components is effectively improved.

[0066] In some embodiments, an installation groove segment 213 (as shown in Figure 15 ) is arranged at the end of the guide groove segment 211 away from the limiting groove segment 212. The diameter of the installation groove segment 213 can be greater than the diameter (d8) of the fourth sub-portion 34, so that the connecting piece 30 can be conveniently installed in the sliding groove 21. It should be noted that when the door plate 11 is in the closed state (as shown in Figure 7 and Figure 9 ), the connecting piece 30 is farthest from the rotating structure 50, and at this time, the connecting piece 30 is located between the rotating structure 50 and the installation groove segment 213, so that the connecting piece 30 is prevented from falling off from the installation groove segment 213.

[0067] Referring to Figure 9 , Figure 13 and Figure 14 , in an embodiment, the support 40 and the connecting piece 30 are connected through a fixing structure 60. The fixing structure 60 includes a second connecting hole 61, a second threaded hole 62, and a fixing screw 63. The second connecting hole 61 is arranged on the connecting piece 30, the second threaded hole 62 is arranged on the support 40, and the fixing screw 63 passes through the second connecting hole 61 and is screwed with the second threaded hole 62, so as to fix the connecting piece 30 to the support 40.

[0068] The connecting piece 30 is fixed on the support 40 through the fixing screw 63, and the structure is simple, the installation is convenient, and the maintenance and repair in the later period are facilitated.

[0069] In some embodiments, the fixing screw 63 can also be replaced by a screw rod. The screw rod is connected in the second threaded hole 62 (the support 40), and the connecting piece 30 rotates relative to the screw rod with the screw rod as the rotation shaft. For specific effects, please refer to the foregoing embodiments, which will not be described here.

[0070] Referring to Figure 1 , Figure 4 and Figure 10 , in an embodiment, the door plate 11 is provided with a support structure 70 away from the hinge between the door plate 11 and the door frame 12. The support structure 70 includes a first support block 71 and a second support block 72. The first support block 71 is arranged on the door frame 12, and the second support block 72 is arranged on the door plate 11. When the door plate 11 is closed, the opposite end faces of the first support block 71 and the second support block 72 in the vertical direction abut against each other.

[0071] In the embodiment, the mutual abutment of the first support block 71 and the second support block 72 ensures the support of the door plate 11 in the closed state, reduces the sinking of the door plate 11 caused by the excessive weight of the door plate 11 or the wear of the door hinge, and thus avoids the occurrence of the situations such as the difficulty in closing the door or the water leakage of the door.

[0072] In some embodiments, one of the first support block 71 and the second support block 72 is a support roller, and the other has a support plane, and the support roller abuts on the support plane when the door plate 11 is closed. Through the arrangement of the support roller, the friction between the first support block 71 and the second support block 72 during the opening and closing of the door plate 11 is reduced, and the door plate 11 can be smoothly opened or closed.

[0073] On the other hand, the application also relates to a container comprising any one of the foregoing limiting assemblies.

[0074] By adopting the technical scheme provided in the embodiments of the application, when the door plate 11 is opened, the connecting piece 30 is moved from the guide groove section 211 to the limiting groove section 212, the end portion of the support piece 40 connected with the connecting piece 30 is limited in position relative to the door plate 11 through the clamping of the connecting piece 30 by the limiting groove section 212, at this time, the door plate 11 is supported by the support piece 40 and has no tendency to be closed, and the safety accidents such as the pinch injury and the collision caused by the accidental closing of the door plate 11 are avoided; when the door plate 11 needs to be closed, the connecting piece 30 is taken out from the limiting groove section 212 to release the limiting state, and the closing operation of the door plate 11 can be realized, the limiting assembly and the door structure 10 are connected as a whole, and the loss of the separate parts during use is avoided; the structure is simple, the use and the later replacement and maintenance are convenient, and the manufacturing cost is relatively low.
