[0021] To make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, rather than all of the embodiments. In the following description, specific details such as specific configuration and components are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures is omitted in the embodiment.

[0022] In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0023] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist at the same time. The term " / and" in this article describes another type of association object relationship, indicating that there can be two relationships. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the previous and next associated objects are in an "or" relationship.

[0024] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusions.

[0025] See also Figure 1-2 , the present invention provides a technical solution of an automatic locking device: comprising a fixed plate 1, a movable door plate 2, a fixed block 3, a first locking block 4, a locking rod 5, a second locking plate 6 and a locking block 8;

[0026] The fixing block 3 is welded to the front of the movable door panel 2, the first locking block 4 and the second locking plate 6 are both welded to the front of the fixing plate 1, the locking rod 5 is welded to the side of the fixing block 3, and the locking block 8 is rotatably connected between the top ends of the first locking block 4 and the second locking plate 6.

[0027] A bayonet is provided on the inner side of the bottom end of the locking block 8 , and the rotation axis of the locking block 8 and the first locking block 4 is close to the side where the fixing plate 1 is located.

[0028] The front sides of the first locking block 4 and the second locking plate 6 are both provided with card slots, which are matched with the locking rod 5. When locking, the card slots and the bayonet openings at the bottom of the locking block 8 surround the locking rod 5 to complete the locking.

[0029] The outer side of the bottom end of the locking block 8 is arc-shaped, and the bottom end of the locking block 8 is located between the two grooves. The top of the locking block 8 is fixedly connected with a toggle plate 7, and the toggle plate 7 is perpendicular to the locking block 8.

[0030] During specific use, when locking, the movable door panel 2 is closed toward the fixed plate 1. At this time, the locking rod 5 contacts the outer side of the bottom end of the locking block 8, thereby lifting the locking block 8, and then the locking rod 5 moves to the slot on the inner side of the bottom end of the locking block 8. The locking block 8 is reset due to the influence of gravity, thereby locking the locking rod 5. When unlocking is required, the toggle plate 7 is lifted to remove the locking rod 5 to complete the unlocking.

[0031] The above description is only the preferred embodiment of the utility model, which does not limit the protection scope of the utility model. For those skilled in the art, the utility model can be modified and varied in various ways.
