DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0033] The present invention provides a portable lock for a military workpiece box. Please refer to Figures 1 - 4 , which includes a first fixed plate 10 and a second fixed plate 20. An L-shaped plate 11 is provided on the first fixed plate 10. A U-shaped rod 27 is connected to the second fixed plate 20 through a connection component, and the U-shaped rod 27 is stuck in the L-shaped plate 11.

[0034] The connection component includes: a side plate 21, a sliding groove 22, a sliding rod 23, a limiting plate 24, a groove 25, a spring 26;

[0035] Both ends of the top of the second fixing plate 20 are fixedly installed with side plates 21. A chute 22 is opened in the side plate 21. A sliding rod 23 is slidably connected in the chute 22. The sliding rod 23 can rotate in the chute 22. A U-shaped rod 27 is fixedly installed between the two sliding rods 23. Limit plates 24 are fixedly installed at the opposite ends of the two sliding rods 23, and the limit plates 24 are in contact with the side plates 21. By setting the limit plates 24, the phenomenon that the U-shaped rod 27 slides left and right can be avoided. Grooves 25 are opened on both sides of the top end of the second fixing plate 20. A spring 26 is fixedly installed at the bottom end of the groove 25. One end of the spring 26 is fixedly installed on the bottom of the U-shaped rod 27, and the spring 26 can expand and contract in the groove 25.

[0036] Working principle of the connecting component: When it is necessary to clamp the U-shaped rod 27 in the L-shaped plate 11, lift the U-shaped rod 27 upward. At this time, the sliding rod 23 will slide in the chute 22, and the spring 26 will also deform until the top end of the U-shaped rod 27 is higher than the L-shaped plate 11. After that, the top end of the U-shaped rod 27 can be clamped in the L-shaped plate 11. Thus, it can be realized that the lid of the military workpiece box can be fixed on the box body of the military workpiece box.

[0037] The first fixing plate 10 is detachably connected to the lid of the military workpiece box through a fixing component, and the second fixing plate 20 is detachably connected to the box body of the military workpiece box through a fixing component.

[0038] The fixing component includes: a rotating shaft 40, a threaded groove 41, a threaded block 42, and a special-shaped hole 43;

[0039] The rotating shaft 40 is rotatably connected in both the first fixing plate 10 and the second fixing plate 20 through bearings. Threaded grooves 41 are opened on both the lid of the military workpiece box and the box body of the military workpiece box. The threaded block 42 is fixedly installed at one end of the rotating shaft 40, and the threaded block 42 is threadedly connected in the threaded groove 41. A special-shaped hole 43 is opened at the other end of the rotating shaft 40, and the other end of the rotating shaft 40 is arranged in the first fixing plate 10 and the second fixing plate 20. Among them, the shape of the special-shaped hole 43 includes but is not limited to a hexagon.

[0040] The fixing component further includes: a limiting component for limiting the positions of the first fixing plate 10 and the second fixing plate 20;

[0041] The limiting component includes: a guiding groove 50 and a guiding rod 51;

[0042] A number of guiding grooves 50 are opened on both the lid of the military workpiece box and the box body of the military workpiece box. A number of guiding rods 51 are fixedly installed on one side of the first fixing plate 10 and the second fixing plate 20, and the guiding rods 51 are slidably connected in the guiding grooves 50. Among them, the shape and size of the guiding groove 50 match the shape and size of the guiding rod 51.

[0043] Working principle of the fixing component: When installing the buckle, first insert a part of the guide rod 51 into the guide groove 50 to limit the position of the buckle. Then, insert an external tool (including but not limited to a screwdriver) into the special-shaped hole 43. Immediately afterwards, the rotating shaft 40 can be driven to drive the threaded block 42 to rotate until the threaded block 42 is threadedly connected to the threaded groove 41. Thus, the installation of the buckle can be achieved.

[0044] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
