[0024] Next, in combination with the drawings and specific embodiments, the present invention will be further described:

[0025] Such as Figure 1 、 23 shows a container door according to a first embodiment of the present invention, which includes a first door panel 10, a second door panel 20, a door lock, a push rod 40, and a support rod assembly 50. The first door panel 10 and the second door panel 20 are arranged opposite to each other at the rear end of the container. When the first door panel 10 and the second door panel 20 are closed, the free end of the first door panel 10 is pressed against the outer side of the second door panel 20. The door lock is used to lock the first panel door 10 on the door frame of the container. In this way, the first door panel 10 and the second door panel 20 are locked by the door lock. The push rod 40 is installed on the first door panel 10. Specifically, the push rod 40 is arranged along The first door panel 10 extends in the thickness direction and is connected to a preset hole on the first door panel 10. The outer end of the push rod 40 extends to the outside of the first door panel 10 and abuts against the door lock, and the inner end extends into the inner side of the inner surface of the first door panel 10 to form an operating end. When the operating end is pressed toward the outside of the first door panel 10, the push rod 40 moves outward toward the door lock, so that the outer end of the push rod 40 can push the door lock to trigger the door lock, thereby opening the door lock on the inner side of the first door panel 10, and then the first door panel 10 and the second door panel 20 can be opened after being pushed inside the container. The support rod assembly 50 includes a support rod 52, a lever rod 51, a screw rod 53, a nut 54, a connecting rod 55 and a connecting rod 56. One end of the support rod 52 and one end of the lever rod 51 are both hinged to the screw rod 53. The nut 54 is sleeved on the screw rod 53 in a threaded manner. One end of the connecting rod 56 is hinged to the middle part of the support rod 52 and the other end is hinged to the nut 54. One end of the connecting rod 55 is hinged to the middle part of the lever rod 51 and the other end is hinged to the nut 54. The other end of the support rod 52 forms a supporting end supported on the inner surface of the second door panel 20, and the other end of the lever rod 51 forms a driving end that presses against the inner surface of the first door panel 10.

[0026] When in use, inside the container, the push rod 40 is pressed to trigger the door lock, the supporting end of the support rod 52 is supported on the second door panel 20, and the driving end of the lever 51 is supported on the first door panel 10. A certain angle is maintained between the support rod 52 and the lever 51. The handle 531 on the screw rod 53 is rotated to drive the screw rod 53 to rotate, and the nut 54 moves along the extension direction of the screw rod 53. The support rod 52 and the lever 51 are pulled toward each other by using the connecting rod 55 and the connecting rod 56. The driving end swings with the lever 51, which applies a thrust to the first door panel 10, pushing the first door panel 10 outward so that the first door panel 10 is pushed open.

[0027] In a preferred embodiment, the present invention hinges the toggle end formed at the other end of the toggle rod 51 on the inner surface of the first door panel 10, so that the strut assembly 50 is connected to the first door panel 10, which can prevent the strut assembly 50 from being lost. At the same time, the strut assembly 50 can be stored on the inner surface of the first door panel 10 to avoid occupying more space inside the container. Further, a storage groove 11 can be provided on the inner surface of the first door panel 10, and the support rod 52, the toggle rod 51, the connecting rod 55 and the connecting rod 56 can be stored together by rotating the screw 53, and the stored strut assembly 50 can be placed as a whole in the storage groove 11, so that the stored strut assembly 50 will not protrude from the inner surface of the first door panel 10, thereby not occupying space inside the container. In addition, in order to facilitate pushing open the first door panel 10 inside the container, the present invention provides a pressing piece on the toggle rod 51, and when the strut assembly 50 is pushed away from the toggle rod 51, a pressing piece is provided. Figure 2 The position of the first door panel 10 is rotated to Figure 1 During the state shown, the pressing member swings toward the inside of the container along with the support rod assembly 50, and the pressing member pushes the operating end of the push rod 40, thereby pushing the push rod 40 toward the outside of the first door panel 10, thereby triggering the door lock. That is to say, when the first door panel 10 needs to be opened from the inside, there is no need to press the operating end of the push rod 40 separately. During the process of taking out the support rod assembly 50, the pressing member can be used to push the operating end of the push rod 40 to trigger the door lock, thereby improving the convenience of use and then improving the success rate of escaping from the inside of the container. The pressing member of the present invention can be a pressure block 57 fixed on the driving end of the lever 51. The outer peripheral curve of the pressure block 57 makes the pressure block 57 form a cam-like component, so that when the pressure block 57 rotates relative to the first door panel 10 as the lever 51 rotates, its outer peripheral edge is used to press the push rod 40. The shape and structure of the pressure block 57 are not limited to this. It can also be other components or mechanisms, such as some reversing mechanisms, which converts the rotation of the lever 51 into movement of the push rod 40 in the thickness direction of the first door panel 10.

[0028] In addition, in order to prevent the support rod 52 from slipping when supported on the inner surface of the second door panel 20, the present invention is provided with a pin shaft 22 on the inner surface of the second door panel 20. When in use, the support end of the support rod 52 is clamped on the pin shaft 22, and the support end of the support rod 52 is limited by the pin shaft 22. A groove 21 is also provided on the inner surface of the second door panel 20, and the pin shaft 22 is arranged inside the groove 21 to prevent the pin shaft 22 from encroaching on the inner space of the container.

[0029] Figure 4The container door of the second embodiment of the present invention is shown, which has a substantially similar structure to the first embodiment, except that, in the second embodiment, when the first door panel is opened, the screw rod is rotated to spread the support rod and the lever, that is, the support rod and the lever are swung away from each other, and when the support end of the support rod is clamped on the second door panel, the driving end on the lever pushes the first door panel outward.

[0030] See also Figure 1 As shown, the door locks in the container doors in the above-mentioned embodiment 1 and embodiment 2 all include a locking rod 33, a handle 31, a lock block 30, and a lock buckle 32, wherein the locking rod 33 is located on the outside of the first door panel 10 and extends along the height direction of the first door panel 10, the handle 31 is connected to the locking rod 33, the locking rod 33 is located on the outside of the first door panel 10 and is pivotally matched with the first door panel 10, and is the same as the locking rod 33 of the existing container. Both ends of the locking rod 33 are also provided with lock heads that match the lock seat on the container door frame. By rotating the locking rod 33, the lock head and the lock seat can be clamped together, or the lock head can be locked. Separated from the lock seat, the lock catch 32 is fixedly intercepted on the handle 31, and the middle part of the lock block 30 is pivotally connected to the first door panel 10, so that the lock block 30 forms a lever structure, and the outer end of the push rod 40 abuts against the inner side of one end of the lock block 30, and the other end of the lock block 30 is provided with a lock hook that cooperates with the lock catch 32. When the first door panel 10 is in a locked state, the lock hook on the Euro Express 30 is buckled on the lock catch 32. When escaping inside the container, the push rod 40 moves outward, and the push rod 40 is used to push one end of the lock block 30, so that the lock hook on the lock block 30 is disengaged from the lock catch 32, and then the push rod 40 is used to trigger the door lock.

[0031] When escaping from the container, the present invention rotates the screw rod to make the support rod and the lever swing towards each other or away from each other. During the swinging process of the lever, it can exert a large thrust on the first door panel, so that the first door panel can be easily pushed open inside the container, thereby improving the success rate of escape.

[0032] The container of the present invention includes the above-mentioned container door, and other structures of the container are the same as those of the container in the prior art, which will not be described in detail here.
