[0094] As Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in a preferred embodiment, an end-frame locking device is provided for a container 100, which may include a base frame 2 and end frames 1. The end frames 1 are foldable relative to the base frame 2. Specifically, two end frames 1 are respectively hinged to both ends of the base frame 2 along its length to pivot between a horizontal and a vertical position. The base frame 2 includes two bottom side beams 26 and a floor 22 laid between the two bottom side beams 26. The two bottom side beams 26 are arranged opposite each other along the width direction of the container 100 and include at least one main lock body 21 and at least one locking element 15. The main lock body 21 is disposed on the base frame of the container 100 and is disposed between the two bottom side beams 26 along its width direction. The locking element 15 is disposed on the end frame 1 of the container 100. The main lock body 21 is positioned corresponding to the locking element 15 so that after the end frame 1 of the container 100 is laid down, the locking element 15 and the main lock body 21 can automatically connect and lock to restrict the end frame 1. The main lock body 21 is constructed such that at least when the main lock body 21 is not in use, the top of the main lock body 21 can not exceed the top of the base frame 2, specifically, it can not exceed the top of the floor 22.

[0095] In some embodiments, the main lock body 21 is used to be installed on the base frame 2 of the container 100, and can be located in the middle of the base frame 2 along the width direction of the base frame 2, which is the Y-axis direction in the figure. Along the length direction of the base frame 2, the main lock body 21 is relatively close to the end of the base frame 2. The specific position needs to be determined according to the position of the locking member 15 after the end frame 1 of the container 100 is folded. The length direction of the base frame 2 is the X-axis direction in the figure. The main lock body 21 and the base frame 2 are fixedly connected and can be fixedly connected by welding. The base frame 2 is provided with a mounting groove for installing the main lock body 21.

[0096] like Figure 1 , Figure 2 as well as Figure 10 As shown, the wall panel of the mounting groove may include two adjacent bottom crossbeams 25 and a connecting plate connecting the two bottom crossbeams 25. That is, the main lock body 21 can be installed between two adjacent bottom crossbeams 25 along its length.

[0097] The locking element 15 is used to install on the end frame 1 of the container 100, and can be located at the middle of the end frame 1 along the width direction of the end frame 1, which is the Y-axis direction in the figure; the locking element 15 and the end frame 1 are fixedly connected.

[0098] The end frame 1 of the container 100 is laid down, and the locking member 15 and the main lock body 21 are automatically connected and locked to limit the end frame 1. After the locking member 15 and the main lock body 21 are connected and locked, the end frame 1 cannot be unfolded. At least when the main lock body 21 is not in use, the top of the main lock body 21 cannot exceed the top of the chassis 2. The chassis 2 is provided with a floor 22, and the top of the chassis 2 is the top of the floor 22. When the main lock body 21 is not in use, the top of the main lock body 21 can be lower than the top of the chassis 2 or flush with the top of the chassis 2.

[0099] When the main lock body 21 is not in use, the main lock body 21 is not connected with the locking member 15, and the main lock body 21 is not operated by the worker, such as unfolding, turning over, etc. When the main lock body 21 is in use, the main lock body 21 is connected with the locking member 15 or in the process of connection. The height of the components of the main lock body 21 can change, and the height of some components of the main lock body 21 can exceed the top of the chassis 2. Since the container 100 is in a folded state or in a folding process at this time, even if the height of some components of the main lock body 21 can exceed the top of the chassis 2, it will not affect the loading space of the container 100.

[0100] The end frame locking device in the embodiment can be achieved by arranging the main lock body 21 in the middle of the chassis 2 of the container 100 and arranging the locking member 15 in the middle of the end frame 1 of the container 100. When the main lock body 21 is not in use, the height of the main lock body 21 does not exceed the top of the chassis 2. The end frame locking device is convenient to lock and unlock, and does not affect the loading of goods on the chassis 2 of the container 100, thereby reducing the influence of the end frame locking device on the loading space of the container 100.

[0101] In some embodiments, the locking member 15 is configured to have an abutting surface, so that after the end frame 1 of the container 100 is laid down, the abutting surface can be located below at least part of the main lock body to form an abutting fit. The locking member 15 can have an abutting surface that can form an abutting fit with at least part of the main lock body 21. In one embodiment, as shown in Figure 1 , Figure 8 , Figure 11 The locking member 15 can be any one of a lock block 11, a lock hole 121, or a top corner piece. The lock block 11 can be a sheet metal piece fixed to the middle of the end frame 1. The lock block 11 can be configured in a long strip shape, an L shape, a U shape, or a square box shape, etc.

[0102] The lock hole 121 can be a hole formed in the middle of the end frame 1. The top corner piece can be a top corner piece in the prior art, such as the top corner piece 14 in the figure. At this time, the top corner piece needs to be arranged in the middle along the width direction of the end frame 1, and the side and top of the top corner piece are provided with connecting holes, so that the main lock body 21 can be connected and locked. Of course, the two sides of the end frame 1 are still provided with the top corner piece 14.

[0103] The base frame 2 may also include a mounting slot recessed into the floor 22 along the height direction of the container 100, in which the main lock body 21 is mounted, such that the top of the main lock body 21 is configured such that, at least when the main lock body 21 is not in use, the top of the main lock body 21 does not exceed the top of the base frame 2.

[0104] In one implementation, such as Figure 1 As shown, the locking block 11 can be constructed in a U-shape. The locking block 11 can protrude along the length direction from the surface of the end frame 1 of the container 100 located in a vertical position. After the end frame 1 of the container 100 is laid down, the locking block 11 can extend into the main lock body 21, thereby connecting and locking with the main lock body 21. The locking block 11 can be fixed to the inner side of the upper beam 12 by welding and protrudes from the inner side of the upper beam 12.

[0105] In another embodiment, the locking block 11 can protrude along the height direction from the surface of the end frame 1 of the container 100 in a vertical position. The main lock body 21 is configured such that when not in use, the top of the main lock body 21 does not exceed the top of the base frame 2. After the end frame 1 of the container 100 is lowered, the locking block 11 can be aligned with the main lock body 21, and when in use, the main lock body 21 can extend beyond the top of the base frame 2 to achieve connection and locking with the locking block 11, specifically forming an abutment fit. For example, it can be implemented as described in detail below. Figure 8 and Figure 9 The main lock body 21 is shown.

[0106] In one implementation, such as Figure 8 As shown, the locking block 11 is U-shaped and protrudes along the height direction from the surface of the end frame 1 of the container 100 in a vertical position. After the end frame 1 of the container 100 is laid down, the locking block 11 can be aligned with the main lock body 21 and adjacent to it along the length direction, thereby achieving connection and locking with the main lock body 21. In this embodiment, the locking block 11 can be fixed to the top of the upper beam 12 by welding and protrudes from the top of the upper beam 12. The base frame 2 can be provided with a clearance groove 24 (see reference). Figure 11 The clearance groove 24 in the illustrated embodiment is used to accommodate at least part of the upper beam 12 and the locking block 11. Of course, if needed and / or desired, the locking block 11 can also be constructed as a strip, an L-shape, or a square, etc.

[0107] In one implementation, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the main lock body 21 can be installed in the mounting slot. The main lock body 21 may include a main bracket 211, a bolt 213, and a lock spring 215.

[0108] The main bracket 211 can include at least two support plates 2111. The support plates 2111 can be fixedly connected to the wall plates of the mounting groove. The support plates 2111 are provided with support holes 2112; the two support plates 2111 are arranged in parallel, and the main bracket 211 can further be provided with a side plate to fix the two support plates 2111, or the two support plates 2111 belong to a U-shaped structural member, as shown in Figure 8 If necessary and / or desired, the main bracket 211 can also be provided with two side plates to fix the two support plates 2111. The two support plates 2111 can be connected between the two side plates (see Figure 5 ).

[0109] The lock tongue 213 can be arranged in the support hole 2112 and can slide in the support hole 2112, and the first end of the lock tongue 213 is provided with a slope, and the locking member 15 can have a driving relationship with the slope of the lock tongue 213 during the process of laying down the end frame 1 of the container 100, and after the end frame 1 of the container 100 is laid down, the lock tongue 213 can extend into the locking member 15 to achieve connection locking.

[0110] In some embodiments, after the end frame 1 of the container 100 is laid down, the lock tongue 213 extends into the U-shaped locking member 15, and when the end frame 1 of the container 100 is moved upward by an external force, the abutting surface (which can be the bottom surface of the locking member 15) of the locking member 15 is located below at least part (for example, the lock tongue 213) of the main lock body, so as to form an abutting fit, thereby blocking the locking member 15 from continuing to move upward, and thereby limiting the end frame 1.

[0111] The lock spring 215 can be sleeved on the lock tongue 213 and arranged between the two support plates 2111 to provide the lock tongue 213 with a reset elastic force.

The lock tongue 213 moves towards the locking member 15 to be advanced, and the lock tongue 213 moves away from the locking member 15 to be retreated.

[0113] As Figure 3 , Figure 4 , Figure 6 , Figure 7As shown, in the process of the lock block 11 extending into the main lock body 21, or the lock block 11 approaching the main lock body 21, the lock block 11 can extrude the lock tongue 213 downward, the lock block 11 and the slope of the lock tongue 213 have a driving relationship, the lock tongue 213 is pushed to retreat, the lock tongue 213 extrudes the lock spring 215 during the retreat, until the lock block 11 passes the first end of the lock tongue 213, the lock tongue 213 is pushed to advance under the action of the lock spring 215, the first end of the lock tongue 213 enters the middle space of the lock block 11, and remains in the plug-in state with the lock block 11, the lock tongue 213 can limit the lock block 11 to retreat, and the lock block 11 and the main lock body 21 are connected and locked.

[0114] As shown in FIG. 1, Figures 11 to 13 As shown, in the process of the lock hole 121 approaching the main lock body 21, the upper end beam 12 can extrude the lock tongue 213 downward, the upper end beam 12 and the slope of the lock tongue 213 have a driving relationship, the lock tongue 213 is pushed to retreat, the lock tongue 213 extrudes the lock spring 215 during the retreat, until the lock hole 121 reaches the first end of the lock tongue 213, the lock tongue 213 is pushed to advance under the action of the lock spring 215, the first end of the lock tongue 213 enters the lock hole 121, and remains in the plug-in state with the lock hole 121, the lock tongue 213 can limit the lock hole 121 to retreat, and the lock hole 121 and the main lock body 21 are connected and locked.

[0115] In one embodiment, Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 The lock tongue 213 is provided with a lock spring fixing pin 214, the first end of the lock spring 215 abuts against the lock spring fixing pin 214, and the second end of the lock spring 215 abuts against the support plate 2111. The lock spring 215 can always remain in a tension state. If the lock tongue 213 retreats, the lock spring 215 will be further extruded. If the lock tongue 213 advances, the lock spring 215 elastically deforms to provide a reset elastic force for the lock tongue 213.

[0116] In some embodiments, as shown in FIG. 1, Figure 3 , Figure 4 The main lock body 21 can further include a connecting rod 2122 and an operation handle 2121.

[0117] The first hinged part (located at the first end of the connecting rod 2122) of the connecting rod 2122 is hinged to the support plate 2111, and the second hinged part (which can be located at or near the middle position of the connecting rod 2122) of the connecting rod 2122 is hinged to the second end of the lock tongue 213. The second hinged part is located above the first hinged part. In the figure, the first end of the connecting rod 2122 is the lower end of the connecting rod 2122, and the second end of the connecting rod 2122 is the upper end of the connecting rod 2122.

[0118] The first end of the operating handle 2121 is a free end, and the second end of the operating handle 2121 is connected to the third hinge part of the connecting rod 2122 (located at the second end of the connecting rod 2122). The third hinge part is located above the second hinge part. The operating handle 2121 can rotate relative to the connecting rod 2122, rotate in a direction away from the locking piece 15, and drive the bolt 213 to retreat through the operating handle 2121, so that the bolt 213 can be separated from the locking piece 15 to achieve unlocking, and rotate in a direction close to the locking piece 15 to reduce the height.

[0119] The connecting rod 2122 and the operating handle 2121 constitute a folding handle 212. The position where the operating handle 2121 is connected to the connecting rod 2122 is provided with a handle rotating shaft 2123, and the operating handle 2121 can rotate around the handle rotating shaft 2123. As shown in Figure 4 , when unlocking is needed, the staff rotates the operating handle 2121 in a direction away from the locking piece 15, and then pulls the operating handle 2121, so that the operating handle 2121 rotates in a direction away from the locking piece 15 to drive the connecting rod 2122 to rotate around the handle rotating shaft 216 in a direction away from the locking piece 15, so as to drive the bolt 213 to retreat through the bolt pin 217, and the bolt 213 can be separated from the locking piece 15 to achieve unlocking. As shown in Figure 3 , after unlocking is completed, the staff can rotate the operating handle 2121 in a direction close to the locking piece 15, or the staff can release the operating handle 2181, and the operating handle 2181 rotates by itself under the action of gravity until the operating handle 2121 is basically parallel to the bolt 213, and the height of the operating handle 2121 can be reduced to the lowest, and the overall height of the main lock body 21 is no longer raised. The top of the supporting plate 2111 can also be provided with a receiving groove for the operating handle 2121 to avoid the operating handle 2121 protruding from the top of the main lock body 21.

[0120] In the embodiments shown in Figure 3 and Figure 4 , the second hinge part of the connecting rod 2122 is provided with a hinge hole 2124, which is configured as a long hole, and the bolt pin 217 connected to the second end of the bolt 213 is arranged in the hinge hole 2124, and the bolt pin 217 can rotate and move in the hinge hole 2124.

[0121] Because the bolt pin 217 can rotate and move in the hinge hole 2124, during the rotation of the connecting rod 2122, the bolt 213 can move in the supporting hole 2112, and there is no interference between the components.

[0122] In some other embodiments, as shown in Figure 6 , Figure 7 , the main lock body 21 can further include a connecting rod 2183, a sliding sleeve 2182, and an operating handle 2181.

[0123] The first hinged part of the connecting rod 2183 (at the first end of the connecting rod 2183) is hinged with the support plate 2111, and the second hinged part of the connecting rod 2183 is hinged with the second end of the lock tongue 213; Figure 6 and Figure 7 In the embodiment shown, the first end of the connecting rod 2183 is the lower end of the connecting rod 2183, and the second end of the connecting rod 2183 is the upper end of the connecting rod 2183.

[0124] In some embodiments, the second hinged part of the connecting rod 2183 can be located at the second end of the connecting rod 2183. In some other embodiments, the second hinged part of the connecting rod 2183 can be located at or near the middle of the connecting rod 2183.

[0125] The sliding sleeve 2182 is arranged on the connecting rod 2183, and the axial direction of the sliding sleeve 2182 can be kept parallel to the length direction of the connecting rod 2183.

[0126] The operating handle 2181 is arranged through the sliding sleeve 2182, and the operating handle 2181 can move in the sliding sleeve 2182 relative to the connecting rod 2183. When the operating handle 2181 is moved upward, the operating handle 2181 is rotated towards the direction away from the locking piece 15, so as to drive the connecting rod 2183 to rotate around the handle rotating shaft 216 towards the direction away from the locking piece 15, thereby driving the lock tongue 213 to retreat via the lock tongue pin 217, so that the lock tongue 213 can be separated from the locking piece 15 to achieve unlocking. When the operating handle 2181 is moved downward, the height can be reduced.

[0127] The connecting rod 2183 and the operating handle 2181 can constitute a telescopic handle 218. The operating handle 2181 can be arranged in an L shape, and a limiting pin is arranged at the lower end of the operating handle 2181. The upper end and the lower end of the operating handle 2181 cannot pass through the sliding sleeve 2182. The inner diameter of the sliding sleeve 2182 is slightly larger than the outer diameter of the operating handle 2181, and the operating handle 2181 can move smoothly in the sliding sleeve 2182.

[0128] As shown in Figure 7 When unlocking is needed, the operating handle 2181 is moved upward by the staff, and then the operating handle 2181 is pulled, so as to drive the lock tongue 213 to retreat, and the lock tongue 213 can be separated from the locking piece 15 to achieve unlocking. As shown in Figure 6 After unlocking is completed, the operating handle 2181 can be moved downward by the staff, or the operating handle 2181 can be released by the staff. The operating handle 2181 falls by itself under the action of gravity, and the height of the operating handle 2181 can be reduced to the lowest, so that the overall height of the main lock body 21 is no longer increased.

[0129] In Figure 6 , Figure 7In the shown embodiment, the second hinge part of the connecting rod 2183 is provided with a hinge hole 2184 configured as a long hole, in which a lock tongue pin 217 connecting the second end of the lock tongue 213 is arranged, and the lock tongue pin 217 can rotate and move in the hinge hole 2184.

[0130] Because the lock tongue pin 217 can rotate and move in the hinge hole 2184, during rotation of the connecting rod 2183, the lock tongue 213 can move in the support hole 2112, and no interference between the components is caused.

[0131] In one embodiment, as shown in Figure 8 and Figure 9 The main lock body 21 further comprises:

[0132] A turnover support 232 is arranged on the base frame 2 and can be fixedly connected with the base frame 2 by welding;

[0133] A turnover bracket 231 is hingedly connected with the first end of the turnover support 232, and the main bracket 211 and the lock tongue 213 are arranged on the second end of the turnover bracket 231. In the figure, the first end of the turnover bracket 231 is the lower end of the turnover bracket 231, and the second end of the turnover bracket 231 is the upper end of the turnover bracket 231. The turnover bracket 231 can rotate relative to the turnover support 232. When the turnover bracket 231 rotates upward, the main bracket 211 and the lock tongue 213 can be raised to a height at which they can be connected with the locking piece 15. When the turnover bracket 231 rotates downward, the height can be lowered.

[0134] The first end of the turnover bracket 231 is hingedly connected with the turnover support 232, and a rotating pin 233 is arranged at the position at which the first end of the turnover bracket 231 is hingedly connected with the turnover support 232. The first end of the turnover bracket 231 can rotate around the rotating pin 233. The rotating pin 233 can be located at a corner of the turnover support 232. When the turnover bracket 231 rotates, it can only rotate about 90 degrees. In this way, even if the end frame 1 hits the main lock body 21, the turnover bracket 231 can still maintain a standing state.

[0135] In some embodiments, the turnover support 232 can be arranged on the bottom cross beam 25 of the base frame 2 to stably support the main lock body 21 as shown in Figure 8 and Figure 9

[0136] In some embodiments, the turnover support 232 can comprise two support plates arranged opposite to each other in the length direction, and the turnover bracket 231 can be hingedly connected between the two support plates in the length direction so as to be able to rotate in the width direction. In this way, even if the end frame 1 hits the main lock body 21 in the length direction, the turnover bracket 231 can still maintain a standing state.

[0137] As shown in Figure 8 and​Figure 9 As shown, when the end frame 1 needs to be limited, the worker usually turns the turnover bracket 231 upward before locking. The turnover bracket 231 can drive the main bracket 211 and the lock tongue 213 to be raised to the height of the locking member 15. At this time, the turnover bracket 231 can exceed the top of the base frame 2. For example, the technical solution can be applied to the situation that the lock block 11 protrudes from the end frame 1 (specifically, the upper end beam 12) in the height direction. At this time, after the end frame 1 is laid down, the lock block 11 is higher than the top of the base frame 2. The turnover bracket 231 can drive the main bracket 211 and the lock tongue 213 to be raised to the height of the locking member 15 (the lock block 11).

[0138] When the end frame 1 does not need to be limited, the worker usually turns the turnover bracket 231 downward after unlocking. The turnover bracket 231 can be lowered in height. At this time, the turnover bracket 231 will not exceed the top of the base frame 2, and the overall height of the main lock body 21 will not be raised. Specifically, the turnover bracket 231 will not exceed the top of the floor 22. This design solution can be applied to the situation that the locking member 15 is far away from the base frame 2 of the container 100, and has a larger adaptive range.

[0139] In one embodiment, as shown in Figure 8 The main lock body 21 further includes:

[0140] The fixed handle 219 is arranged at the second end of the lock tongue 213. The fixed handle 219 can drive the lock tongue 213 to retreat, so that the lock tongue 213 can be separated from the locking member 15 to achieve unlocking.

[0141] The fixed handle 219 is annular to facilitate gripping. The fixed handle 219 can be fixedly connected with the second end of the lock tongue 213 by welding. The fixed handle 219 can not exceed the top of the base frame 2 in the height direction.

[0142] When unlocking is needed, the worker pulls the fixed handle 219 to drive the lock tongue 213 to retreat, so that the lock tongue 213 can be separated from the locking member 15 to achieve unlocking. After unlocking is completed, the worker can release the fixed handle 219. The lock tongue 213 automatically advances to reset under the elastic force of the lock spring 215, and the fixed handle 219 also automatically advances to reset.

[0143] In some embodiments, the end frame locking device can include at least two main lock bodies 21 and at least two locking members 15. The at least two main lock bodies 21 are arranged at intervals in the width direction. The at least two locking members 15 are arranged at intervals in the width direction. The number of the at least two main lock bodies 21 corresponds to the number of the at least two locking members 15. The positions of the at least two main lock bodies 21 correspond to the positions of the at least two locking members 15, respectively. For example, Figure 10In the illustrated embodiment, the end frame locking device includes two main lock bodies 21 and two locking members 15. The two main lock bodies 21 can be symmetrically arranged along a center line in the width direction of the container 100. Understandably, the two locking members 15 are also symmetrically arranged along the center line in the width direction of the container 100. As shown in Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 and Figure 12 The second aspect of the utility model further provides a container 100, which comprises the end frame locking device of any of the above-mentioned solutions.

[0144] In one embodiment, as shown in Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 and Figure 12 The container 100 can comprise a chassis 2 and an end frame 1. The chassis 2 can comprise a floor 22 and two bottom side beams 26 arranged opposite in the width direction.

[0145] The main lock body 21 of the end frame locking device is arranged on the chassis 2 and between the two bottom side beams 26 in the width direction. The main lock body 21 is in fixed connection with the chassis 2. The width direction of the chassis 2 is the Y-axis direction in the figure, and the length direction of the chassis 2 is the X-axis direction in the figure.

[0146] The end frame 1 is arranged at the end of the chassis 2. The chassis 2 can be hingedly connected with the lower end of the end frame 1. The end frame 1 can be folded relative to the chassis 2. The locking member 15 of the end frame locking device is arranged on the top of the end frame 1. The width direction of the end frame 1 is the Y-axis direction in the figure. The position of the main lock body 21 corresponds to the position of the locking member 15, so that after the end frame 1 is laid down, the locking member 15 and the main lock body 21 can be automatically connected and locked to limit the end frame 1.

[0147] In one embodiment, as shown in Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 and Figure 12 The end frame 1 can comprise an upper end beam 12 and two corner columns 13. The upper end beam 12 can be recessed in the thickness direction of the end frame 1 or flush with the corner columns 13.

[0148] The locking member 15 is arranged on the upper end beam 12 and between the two bottom side beams 26 in the width direction. In some embodiments, the locking member 15 can be arranged at the middle of the upper end beam 12. For example, the lock block 11 can be a sheet metal part fixed at the middle of the upper end beam 12; the lock hole 121 can be a hole formed at the middle of the upper end beam 12; and the top corner member can be a top corner member in the prior art fixed at the middle of the upper end beam 12.

[0149] Two corner posts 13 are arranged opposite to each other in the width direction. The upper end of the corner post 13 is connected to the upper end beam 12, and the lower end of the corner post 13 is connected to the base frame 2 in a hinged manner.

[0150] The end frame 1 can be rotated around the position hinged to the base frame 2, and when the end frame 1 is laid over the base frame 2, the container 100 is in a folded state. When the end frame 1 is rotated to be substantially perpendicular to the base frame 2, the container 100 is in an unfolded state.

[0151] In one embodiment, as shown in Figure 11 、 Figure 12 , the base frame 2 is provided with a relief groove 24 corresponding to the end frame 1, and the upper end beam 12 can enter the relief groove 24 after the end frame 1 is laid down, so that the locking member 15 is connected to the main lock body 21.

[0152] This design scheme can be applied to the technical scheme in which the lock block 11 protrudes in the height direction from the end frame 1 (specifically, the upper end beam 12) in the vertical position, and at this time, the upper end beam 12 can be recessed in the thickness direction of the end frame 1. At this time, the upper end beam 12 and the lock block 11 are located in the relief groove 24 and can be aligned with the main lock body 21 (specifically, the lock tongue 213) to achieve connection locking. In the length direction, the relief groove 24 is located between its adjacent bottom cross beam 25 and mounting groove.

[0153] This design scheme is more suitable for the scheme in which the locking member 15 is a lock hole 121 (see Figure 13 ), because at this time the lock hole 121 needs to be lowered in front of the lock tongue 213 to achieve connection locking with the lock tongue 213, and the lock tongue 213 is lower than the top of the base frame 2, so the lock hole 121 also needs to be lowered below the top of the base frame 2.

[0154] If the end frame 1 is also provided with other cross beams, the base frame 2 is also provided with a relief groove 24 corresponding to the other cross beams, and the other cross beams can enter the corresponding relief groove 24 after the end frame 1 is laid down, so that the end frame 1 cannot be completely laid down. After folding, the upper surface of the end frame 1 can be lower than the top of the floor 22, or flush with the top of the floor 22.

[0155] According to the end frame locking device and the container of the utility model, the main lock body is arranged in the middle of the base frame of the container, and the locking member is arranged in the middle of the end frame of the container. The main lock body is provided with a folding handle, or a telescopic handle, or a turnover support. When the main lock body is not used, it does not exceed the top of the base frame, which realizes convenient locking and unlocking operation, and does not affect the loading of goods on the base frame of the container, and reduces the influence of the end frame locking device on the loading space of the container.

[0156] The utility model solves the problem that folding container two sides are inconvenient to set or operate end frame locking device, for example, folding container adds extension angle column, cannot pass the top corner spare on end frame to lock end frame again, folding container adds extension angle column is convenient, also can set up on the folding container of two sides of the box body cannot arrange traditional locking device.
