Description

Technical Field

[0001] The invention belongs to the technical field of tool box storage equipment, and in particular relates to a tool box with a locking mechanism. Background Art

[0002] In current production and life, toolboxes are one of the necessary industrial products. The internal storage space can store a variety of tools for easy storage and use. When there are many toolboxes, the toolboxes usually need to be stacked for storage to reduce the space occupied.

[0003] For example, Chinese utility model patent CN208391993U discloses a stacking tool box, including a box body, which is stacked by a fixed buckle and a movable buckle. When in use, the movable buckle of the lower box body is rotated to make the movable buckle vertical. At this time, the buckle groove of the movable buckle buckles the fixed buckle of the upper box body, and the end of the lock head in the movable buckle is just embedded in the groove in the middle of the rotating shaft. At this time, the two overlapping box bodies are connected into one. However, this stacking connection method is easily affected by external collisions, resulting in failure of the stacking connection, so the structural stability is poor. Summary of the invention

[0055] The locking status of stacked tool boxes is as follows: Fig. 9 shown.

[0056] The working principle of the tool box with locking mechanism of the present invention is as follows:

[0057] 1. When stacking and locking the toolboxes:

[0058] First, place the lower toolbox at a suitable position, and tilt the side of the upper toolbox with the clamping block 22 downward, so that the clamping block 22 is clamped into the clamping groove 21 of the lower toolbox;

[0059] Then lay the upper toolbox flat, and the locking hook 8 falls into the groove 1 of the lower toolbox. The edge of the locking groove 2 squeezes the locking hook 8, compressing the second elastic member 10 to shrink, and the locking hook 8 continues to move downward and falls into the locking groove 2 to clamp, thereby realizing the stacking and locking of the toolboxes.

[0060] 2. When the toolbox is unlocked:

[0061] The unlocking process of stacked tool boxes is as follows: Figure 11-12 shown.

[0062] First, place a finger in the push groove 20 and pull the push groove 20 upward, driving the unlocking member 5 to move upward relative to the lock member 6, and the lock unlocking shaft 19 moves downward along the second convex ridge 18 in the lock unlocking portion 16. Under the extrusion of the back of the unlocking member 5, the upper part of the lock member 6 rotates leftward around the rotation axis 7, and the lower part of the lock member 6 rotates rightward around the rotation axis 7 accordingly. The second elastic member sleeve column 15 squeezes the second elastic member 10 to move into the second elastic member installation groove 13, and the lock hook 8 is disengaged from the locking groove 2;

[0063] Then, the upper tool box is lifted upwards to completely disengage the locking member 6 from the locking groove 2; the upper tool box is then tilted to disengage the clamping block 22 from the clamping groove 21, thereby unlocking the tool box.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
