The guide sleeve 54 not only protects the safety and stable operation of the first locking rod 20 or the second locking rod 29, but also enables the first locking rod 20 or the second locking rod 29 to move up and down more smoothly.

[0033] like Figure 3a and Figure 3b As shown, the inner door panel 4 is arranged on the inner side of the door frame 5, and the outer door panel 6 is arranged on the outer side of the door frame 5. The outer door panel 6 is detachably provided with a handle mounting plate 7, and the inner door panel 4 is correspondingly provided with a detachable inner mounting plate 31. The mounting holes 35 around the handle mounting plate 7 and the inner mounting plate 31 correspond to the cross beam 33 and the vertical beam 34 around the lock body mounting plate 17. The handle mounting plate 7 or the inner mounting plate 31 is installed on the cross beam 33 and the vertical beam 34 along the mounting holes 35 around the handle mounting plate 7 or the inner mounting plate 31 by screws. When the door lock structure 30 fails and needs maintenance, the handle mounting plate 7 or the inner mounting plate 31 can be disassembled. The handle mounting plate 7 is provided with an arc-shaped slide groove 52. Furthermore, the slide groove 52 is a 1 / 4 arc. One end of the handle 12 is slidably connected in the slide groove 52. The other end of the handle 12 is connected to the first rotating shaft 24. When one end of the handle 12 moves along the slide groove 52, the first rotating shaft 24 is driven to rotate, thereby controlling the first locking rod 20 and the second locking rod 29 to complete the locking or unlocking operation. The setting direction of the slide groove 52 and the direction to open or lock the door lock can be set by technicians in this field as needed, which can be as follows: Figure 2a The directions and positions shown can also be Figure 2c The slide groove 52 is arranged in the direction and position shown, and the present invention does not impose any special limitation on this. A plurality of hinges 9 are arranged on the side of the outer door panel 6 for connecting with the door column 3 .

[0034] like Figure 2aAs shown, the container includes two upper and lower door beams 2 and two left and right door posts 3. The door posts 3 include corner posts 46 and corner fittings 8. The corner posts 46 and corner fittings 8 can be integrally formed or separately formed. A step is formed between the corner fittings 8 and the corner posts 46. The door beam 2 is installed on the corner fittings 8. The left and right container doors 1 are respectively hinged to the door posts 3 on the left and right sides through hinges 9. The door posts 3 are provided with corresponding lock slots 10. The handle 12 is used to control. In the locked state, the first lock rod 20 and the second lock rod 29 are inserted into the lock slot 10 for locking. The lock slot 10 is also provided with a guide sleeve 54. In the unlocked state, the first lock rod 20 and the second lock rod 29 are separated from the lock slot 10 for unlocking. A seal is provided at the joint of the left and right container doors 1, the edge of each container door 1 and the joint of the upper and lower door posts 3 or the upper and lower door beams 2 to prevent water leakage.

[0035] Example 2

[0036] like Figure 6a As shown, different from Example 1, the door lock mounting plate 17 is mounted on the inner door plate 4, the first lock rod 20 is in the shape of a slide plate, the second lock rod 29 is in the shape of a clamping column, and the connecting end of the first lock rod 20 and the second lock rod 29 is provided with an elongated hole 47, and the first folding rod 22 and the second folding rod 28 are slidably connected in the elongated hole 47 through a limiting column 48, so that when the first rotating shaft 24 rotates, the first folding rod 22 drives the first lock rod to move up and down in the vertical direction, and the second folding rod 28 drives the second lock rod 29 to move up and down in the vertical direction. Further, a groove 14 is provided on the outer side of the first lock rod 20, and teeth 15 are provided on the groove 14; an auxiliary baffle 51 is provided on the inner side of the first lock rod 20; clamping grooves 21 are provided on both sides of the lock body mounting plate 17; as shown in FIG. Figure 7a As shown, the inner door panel 4 is provided with a slide rail plate 38 on both sides of the lock body mounting plate 17, and the slide rail plate 38 is provided with a third limiting groove 39, and the slide rail plate 38 is slidably connected with a rack 40, as shown in FIG. Figure 7b As shown, a second rotating shaft 41 and a third rotating shaft 44 are arranged on each side of the inner door panel 4, and the outer wall of the second rotating shaft 41 is fixedly connected with a first gear 42, which meshes with the rack 40; the outer wall of the third rotating shaft 44 is fixedly connected with a second gear 45, which meshes with the teeth 15 on the first lock rod 20; a toothed belt 43 is arranged on the outer sleeve of the second rotating shaft 41 and the third rotating shaft 44, so that the second rotating shaft 41 and the third rotating shaft 44 rotate synchronously; the second gear 45 meshes with the teeth 15, and when the first lock rod 20 moves upward, it drives the rack 40 to be inserted into the slot 21, so that the lock body mounting plate is firmly installed on the inner door panel 4.

[0037] Furthermore, extension plates 18 are provided at the top and bottom of the lock body mounting plate 17. The top extension plate 18 is slidably connected to the first locking rod 20 through a first limiting groove 19 opened thereon, and the bottom extension plate 18 is slidably connected to the second locking rod 29 through a second limiting groove 36 opened thereon.

[0038] Furthermore, an auxiliary baffle 51 is detachably provided on the inner side of the first lock rod 20, which can be detachably installed in the form of plugging or snapping. After the lock body mounting plate 17 is installed, the auxiliary baffle 51 is installed on the first lock rod 20. At this time, the auxiliary baffle 51 is just located above the extension plate 18. The purpose of the auxiliary baffle 51 is to prevent the first lock rod 20 from moving further downward so that the lock body mounting plate 17 will not be detached after installation. When the lock body mounting plate 17 needs to be removed for maintenance, the auxiliary baffle 51 is removed.

[0039] Furthermore, a mounting frame 37 is provided on the inner door panel 4, and a through hole 11 is correspondingly provided on the mounting frame 37 for the first locking rod 20 and the second locking rod 29 to pass through. When installing the door lock structure 30, the lock body mounting plate 17 is clamped in the mounting frame 37 to complete the preliminary installation. The second gear 45 and the teeth 15 are in meshing state, and the first rotating shaft 24 is rotated by a tool to drive the first lock plate 23 and the second lock plate 25 to rotate synchronously. At this time, the first folding rod 22 drives the first locking rod 20 to move upward, and the second folding rod 28 drives the second locking rod 29 to move downward. The meshing of the teeth 15 and the second gear 45 drives the second gear 45, the toothed belt 43, and the first gear 42 to rotate, and the meshing of the first gear 42 and the rack 40 drives the racks 40 on both sides to be inserted into the corresponding slots 21 on both sides. At this time, the two racks 40 make the lock body mounting plate 17 stably pressed and fixed, and the fixed installation of the lock body mounting plate 17 is completed. When the first lock rod 20 continues to move upward, the teeth 15 and the second gear 45 are no longer meshed, that is, the rack 40 is no longer in motion, and therefore, the subsequent door locking operation is not affected. When unlocking, the first lock rod 20 moves downward, and when the teeth 15 and the second gear 45 are just about to mesh, the auxiliary baffle 51 restricts the first limit slide plate 20 from moving downward, preventing the rack 40 from disengaging from the slot 21, causing the lock body mounting plate 17 to fall off and move. If it is necessary to disassemble the lock body mounting plate 17, remove the auxiliary baffle 51, continue to rotate the first rotating shaft 24, and make the first lock rod 20 continue to move downward, the teeth 15 and the second gear 45 mesh to drive the second gear 45, the toothed belt 43, and the first gear 42 to rotate, and the meshing action of the first gear 42 and the rack 40 drives the racks 40 on both sides to disengage from the slot 21, completing the disassembly of the lock body mounting plate 17.

[0040] In this embodiment, the frame 32 of the door frame 5 is also provided with a through hole 11 matching the first locking rod 20 and the second locking rod 29. When locking the door, the first locking rod 20 and the second locking rod 29 pass through the through hole 11 of the frame 32 and enter the locking groove 10 on the door beam 2 to be locked. Other structures refer to embodiment 1.

[0041] The present invention installs the door lock structure 30 on the door frame 5 or the inner door panel 4, and only provides the handle 12 for operation on the outer door panel 6. This hidden lock rod door structure has a simple and beautiful appearance, is easy and convenient to operate, and is safe and reliable.
