DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] Example 1: Please refer to Figure 1-6The utility model: a container door lock rod device, including a container 1, a container door 2 is rotatably installed at one end of the container 1, a lock rod 3 is installed on the container door 2, a lock bar 4 is fixedly connected to the lock rod 3, the end of the lock bar 4 away from the lock rod 3 is toothed, and the two lock bars 4 are adapted to each other at the notches at the opposite ends, an inner groove 5 is provided at the end of the lock bar 4 away from the lock rod 3, a lock core 6 is embedded in the inner groove 5 and is slidably connected, a lock groove 7 is provided at the side wall position of the lock bar 4 relative to the lock core 6, the lock core 6 is adapted to the lock groove 7 and is plug-in connected, a push plate 8 is fixedly connected to the opposite side of the two lock cores 6, and the push plate 8 is connected to the two lock bars 4 is penetrated and slidably connected to the side wall on the opposite side, and a reset groove 9 is opened on the opposite side of the two lock bars 4. The inner wall of the lock bar 4 near the reset groove 9 and the inner receiving groove 5 is penetrated and slidably connected to the limit plate 10. A limit groove 11 is opened on the side of the lock core 6 relative to the limit plate 10. The limit plate 10 is adapted to be plugged into the limit groove 11. A magnetic suction plate 12 is fixedly connected to the side of the limit plate 10 near the opening of the reset groove 9. The two magnetic suction plates 12 are magnetically attracted to each other, so that the limit plate 10 can be pulled out of the limit groove 11, and then the lock core 6 can be inserted into the lock groove 7 to complete the rapid locking of the door.

[0024] A No. 1 spring 13 is fixedly connected between the side of the magnetic attraction plate 12 close to the reset groove 9 and the inner wall thereof, and a No. 2 spring 14 is fixedly connected to the inner end of the lock core 6 and the side opposite to the opening of the inner receiving groove 5, and the other end of the No. 2 spring 14 is fixedly connected to the inner groove wall opposite to the inner receiving groove 5. After the magnetic attraction plate 12 is separated by the No. 1 spring 13, the magnetic attraction plate 12 is reset to the reset groove 9, and then the limit plate 10 can be inserted into the limit groove 11, and the lock core 6 can be locked and used more conveniently through the No. 2 spring 14.

[0025] Example 2: Reference Figure 4-6 , further improved on the basis of Example 1:

[0026] The inner end of the lock core 6 is penetrated by and slidably connected with a sliding rod 15, and the sliding rod 15 is fixedly connected to the inner groove of the inner receiving groove 5. Through the limitation of the sliding rod 15, the lock core 6 can move more stably in the inner receiving groove 5, and the push plate 8 is fixedly connected with shielding plates 16 on both sides parallel to the inner receiving groove 5. When the lock core 6 moves to lock and unlock, the shielding plate 16 can shield and protect the opening of the inner receiving groove 5 to ensure the stable use of the lock bar 4. The end of the limiting plate 10 away from the magnetic suction plate 12 is provided with an inner recessed groove 17, and the inner recessed groove 17 is V-shaped. Through the V-shaped inner recessed groove 17, the limiting plate 10 and the limiting groove 11 are engaged after being plugged in. When the box door 2 is opened and the lock bar 4 is not locked, the lock core 6 can be more stably prevented from popping out in the inner receiving groove 5.

[0027] The working principle of the utility model is as follows: when in use, after the container 1 is filled with goods, the box door 2 is rotated to close, and then the lock rod 3 is rotated to make the two lock strips 4 parallel to each other. When the two lock strips 4 are parallel to each other, the two magnetic suction plates 12 are aligned and magnetically attracted to each other. At this time, the magnetic suction plate 12 moves from the reset groove 9 to the outside of the groove, and drives the limit plate 10 to be pulled out of the limit groove 11. During the process, the No. 1 spring 13 is stretched. When the limit plate 10 releases the limit of the lock core 6, the lock core 6 rebounds through the contraction of the No. 2 spring 14, and the lock core 6 can be moved outward in the inner receiving groove 5. When the lock core 6 is moved to the side, the lock core 6 is inserted into the lock groove 7 to complete the locking of the two lock strips 4. During the movement of the lock core 6, the sliding bar 15 is limited to ensure the stability of the movement of the lock core 6 in the inner receiving groove 5. When disassembly is required, the push plate 8 is pushed to move the lock core 6 into the inner receiving groove 5, and then the lock core 6 is separated from the lock groove 7. The locking of the two lock strips 4 is released, and then the locking rod 3 is rotated to separate the two lock strips 4. At this time, the two magnetic plates 12 are separated, and the No. 1 spring 13 rebounds, so that the limiting plate 10 is inserted into the limiting groove 11, so that the components of the lock strip 4 can be reset and the unlocking is completed.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
