[0016] At present, the mainstream containers on the market all adopt the structure of outward-opening doors. In the case of space in the cabin or yard or special transportation, the container cannot be opened normally due to space limitations. For this reason, the inventor thought of setting the container door to open inward. However, the lock seat of the existing container is installed on the front of the door frame beam, and the upper and lower ends of the lock rod extending longitudinally outside the door need to cross the upper and lower beams of the door respectively to engage with the lock seat. The interference between the end of the lock rod and the door frame beam is one of the important reasons why the door cannot be opened inward.

[0017] One of the purposes of the invention disclosed in the present invention is to solve the problem of interference between the lock rod and the lock seat. The embodiments of the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0018] In a preferred embodiment of the present disclosure, please refer to Figure 1The container includes a door 1 and a box body 2. The box body 2 includes an upper door frame cross beam 3 and a lower door frame cross beam 4. The door 1 has a plurality of longitudinally arranged locking rods 5. The two ends of the locking rod 5 are respectively provided with an upper lock head 6 and a lower lock head 7. The container also includes an upper lock seat 8 and a lower lock seat 9. After the door 1 is closed, the locking rod 5 is rotated to make the upper lock head 6 dock with the upper lock seat 8, and the lower lock head 7 dock with the lower lock seat 9, so as to lock the door 1. The upper end of the locking rod 5 and the upper lock seat 8 are lower than the lower edge of the upper door frame cross beam 3 in the longitudinal direction, and the upper lock seat 8 leaves the upper door frame cross beam 3 and is arranged in front of the upper lock head 6. The lower end of the locking rod 5 and the lower lock seat 9 are higher than the upper edge of the lower door frame cross beam 4 in the longitudinal direction, and the lower lock seat 9 leaves the lower door frame cross beam 4 and is arranged in front of the lower lock head 7.

[0019] One end of the box body 2 is provided with a door frame, and the door frame includes a pair of door frame cross beams and a pair of door frame vertical beams, and the pair of door frame cross beams are respectively an upper door frame cross beam 3 and a lower door frame cross beam 4. The box door 1 can be a single leaf or two leaves that open opposite each other. The locking rod 5 is arranged on the outer side of the box door 1 along the vertical extension, and each box door 1 is provided with at least one locking rod 5, typically, it can be 1, 2 or 3. The locking rod 5 is constructed to rotate around its axial central axis. When the locking rod 5 rotates, the lock head at the end of the locking rod 5 will also rotate. During the rotation of the lock head, at least when it is rotated to a certain angle, the upper lock head 6 can be locked with the upper lock seat 8, and the lower lock head 7 can be locked with the lower lock seat 9. At the same time, when it is rotated to another certain angle, the upper and lower lock heads can be separated from the upper and lower lock seats respectively. These features of the container are mostly seen in existing containers, and this embodiment uses these existing technologies here.

[0020] Different from the prior art, the preferred embodiment of the present disclosure uses a shorter locking rod 5, so that the upper lock head 6 at the upper end of the locking rod 5 is located lower than the lower edge of the upper door frame beam 3 in the longitudinal direction, and the lower lock head 7 at the lower end of the locking rod 5 is located higher than the upper edge of the lower door frame beam 4 in the longitudinal direction, and the position of the lock seat is adjusted to be away from the door frame beam and correspondingly arranged in front of the lock head, thereby solving the problem that the door 1 cannot be opened inwards due to the interference of the door frame beam with the lock rod 5 when the rotation angle of the door 1 covers the inside of the box without affecting the locking connection between the lock head and the lock seat.

[0021] In one embodiment, please refer to Figure 2The upper door frame cross beam 3 is provided with an upper mounting seat 10, which extends forward and then downward from the upper door frame cross beam 3, and an upper locking seat 8 is provided on the side opposite to the upper lock head 6 of the downwardly extending portion of the upper mounting seat 10, so that the upper locking seat 8 is lower than the upper door frame cross beam 3 and can be docked with the upper lock head 6. The lower door frame cross beam 4 is provided with a lower mounting seat 11, which extends forward and then upward from the lower door frame cross beam 4, and a lower locking seat 9 is provided on the side opposite to the lower lock head 7 of the upwardly extending portion of the lower mounting seat 11, so that the lower lock seat 9 is higher than the lower door frame cross beam 4 and can be docked with the lower lock head 7. Typically, the upper mounting seat 10 and the lower mounting seat 11 are specifically plates with L-shaped structures, for example, the upper mounting seat 10 and the lower mounting seat 11 can be selected from angle steels of suitable sizes. The upper mounting seat 10 can be long, and it extends continuously along the extension direction of the upper door frame cross beam 3, and can cover each upper lock head 6. Of course, the upper mounting seat 10 can also be a plurality of short ones, which are spaced apart on the upper door frame cross beam 3 and correspond one by one with each upper lock head 6. The lower lock seat 9 can also be fixed in front of the lower lock head 7 in a similar specific manner.

[0022] In one embodiment, a sealing strip is provided along the inner side of the door frame. For example, the cross section of the sealing strip may be J-shaped, and the sealing strip may be fixed to the door frame by means of a pressure strip and rivets.

[0023] The hinges for rotating the door beams of existing container doors and the door frame beams of the container body are usually arranged outside the container. The rotation angle of the door is limited outside the container due to the door frame beams. Therefore, the second purpose of the invention disclosed in the present invention is to provide a container with an inwardly opening door.

[0024] In one embodiment of the present disclosure, please refer to Figure 3 The box body 2 includes a door frame vertical beam 12, and the box door 1 includes a door vertical beam 13. The door vertical beam 13 is rotatably connected to the door frame vertical beam 12 through a hinge plate 14, and the hinge plate 14 is installed on the inner side of the box body 2. Specifically, one end of the hinge plate 14 is directly or indirectly hinged to the inner side of the door frame vertical beam 12, and the other end is fixedly connected to the door vertical beam 13 by, for example, welding. The indirect hinge mentioned here, for example, is that the hinge plate 14 is hinged to the adapter (not shown in the figure) welded and fixed to the inner side of the door frame vertical beam 12, thereby indirectly hinged to the door frame vertical beam 12. The position of the hinge plate 14 is adjusted so that the rotation angle of the box door 1 at least covers the inside of the box. In addition, the improvement of the lock rod 5 and the lock seat disclosed in the present invention removes the external restriction of the inward opening of the box door 1, thereby realizing the inward opening of the container box door 1 of this embodiment.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
