[0005] In the above three patent solutions, the upper cover and the box body are locked by a rotatable buckle installed on the upper cover and locked with the edge of the box opening. In order to enhance the sealing effect, it is necessary to ensure that the locking force between the upper cover and the box body is large enough, which means that the lock structure must be able to provide sufficient pressure to maintain the sealing state. However, as the locking force increases, the difficulty of unlocking also increases accordingly. In order to solve this problem, a lock structure that saves effort in unlocking is proposed in modern design. Summary of the invention

[0006] The utility model aims to solve one of the technical problems in the related art to a certain extent. To this end, the utility model proposes a lock structure, in which the combination of the first clip and the second clip forms a lever structure.

The second fastener can swing relative to the first fastener, and when the second fastener swings to the maximum stroke, the limiting protrusion abuts against the protrusion.

[0011] After adopting the above structure, the first latch and the second latch are combined to form a lever structure. When unlocking, the second latch swings relative to the first latch until the limit protrusion hits the protrusion. Continue to move the second latch, and the second latch drives the first latch to move away from the locking flange until the locking protrusion is disengaged from the locking flange to complete the unlocking. This design optimizes the operating experience, reduces the operating force when unlocking, and maintains sufficient locking force. Such an innovative design improves the practicality and reliability of the box, and further improves the user experience.

[0043] like Figure 7-12 As shown, in this embodiment, a locking structure is disclosed, including:

[0044] A first fastener 3, one end of which is provided with a hinge portion 32 for hinged connection with the upper cover 1, and the other end of which is provided with a protrusion 33 and a locking protrusion 31 for locking and cooperating with the locking flange 21 of the box body 2, and the first fastener 3 has a through groove 34 running through both sides thereof;

[0045] The second fastener 4 is rotatably installed in the through groove 34, and the second fastener 4 has a wrench portion 42 and a limiting protrusion 43 located on the edge of the wrench portion 42. The second fastener 4 can swing relative to the first fastener 3. When the second fastener 4 swings to the maximum stroke, the limiting protrusion 43 abuts against the protrusion 33.

[0046] Further, in this embodiment, the first latch 3 has an inner side facing the outer surface of the upper cover 1, and an outer side away from the outer surface of the upper cover 1. The through slot 34 runs through both the inner and outer sides of the first latch 3, and the length of the through slot 34 is shorter than the length of the first latch 3. That is, the through slot 34 starts at the edge of the protrusion 33 and ends at a position spaced from the edge of the hinge 32.

[0047] Furthermore, in this embodiment, the protrusion 33 is formed by extending the first clip 3 toward one end away from the hinge 32, and the locking protrusion 31 is formed by extending the first clip 3 toward the inside. The second clip 4 has a long arm 41 for embedding into the through slot 34, one end of the long arm 41 is rotatably connected to the through slot 34, and the other end is provided with the wrench portion 42, and the wrench portion 42 is connected to the long arm 41 as a whole; the wrench portion 42 is used for the user to move the second clip 4 with his fingers. The wrench portion 42 has a contour structure 44 that avoids the protrusion 33; the configuration of the contour structure 44 is used to avoid interference between the protrusion 33 and the handle portion during the swinging of the second clip 4 relative to the first clip 3. The first hinge shaft 35 on the first clip 3 is arranged in parallel with the second hinge shaft 45 on the second clip 4. The wrench portion 42 is located on the outer side of the first clip 3 away from the hinge 32.

[0048] Furthermore, in this embodiment, in the natural state, the outer surface of the long arm 41 is flush with the outer surface of the first latch 3. During the unlocking process of the lock structure, the second latch 4 is pushed outward to swing outward relative to the first latch 3 until the limiting protrusion 43 abuts against the protrusion 33, and the second latch 4 is pushed outward to drive the first latch 3 to swing outward. The first latch 3 is disengaged from the locking flange 21 to complete the unlocking.

[0049] Combination Figure 1-6 As shown, in this embodiment, a box body 2 is disclosed, including an upper cover 1, a box body 2 and the locking structure described in this embodiment. One side of the upper cover 1 is rotatably connected to the same side of the box body 2. An illumination device 7 is provided on the inner surface of the upper cover 1. A button switch 6 for triggering the circuit connection of the illumination device 7 is provided between the upper cover 1 and the box body 2.
