[0020] Please see Figures 1 to 4 A locking structure for locking a box body and a box lid includes a first locking assembly 10 and a second locking assembly 20 movably connected; wherein the first locking assembly 10 includes a lock seat 101 installed on the box lid or the box body; the side of the lock seat 101 is provided with a slot 102;

[0021] The second locking assembly 20 includes a fixing plate 201, a first fastener 202, and a second fastener 203. The fixing plate 201 is installed on the box body or box cover, and the side of the fixing plate 201 is provided with a fixing seat 204 and a latch 205. The first end of the first fastener 202 is rotatably installed on the fixing seat 204, and the second end of the first fastener 202 is provided with a latch 206 for the latch 205 to engage. When the first end of the first fastener rotates relative to the fixing seat 204, the latch 205 can engage in the latch 206. The first end of the second fastener 203 is rotatably installed on the first end of the first fastener 202, so that when the first end of the first fastener 202 rotates relative to the fixing seat 204, the second fastener 203 is driven to move relative to the first fastener. The second end of the second fastener 203 is provided with a hook 207 for engaging in the latch groove 102.

[0022] With the box body and lid locked, the latch 205 engages with the latch 206, and the hook 207 engages with the slot 102.

[0023] Specifically, when the lid is closed on the box body, the second fastener 203 is rotated relative to the first end of the first fastener 202, so that the hook 207 of the second fastener 203 engages with the upper part of the slot 102 (at this time, there is a gap between the hook 207 and the slot 102 to allow the second fastener 203 to move as the first fastener 202 rotates). Then, the second end of the first fastener 202 is rotated toward the latch 205. Since the first end of the second fastener 203 is connected to the first end of the first fastener 202, when the first fastener 202 rotates, it drives the latch 205 of the second fastener 203 to move toward the inside of the slot 102. When the second end of the first fastener 202... When the latch 205 and the latch 206 are engaged, the latch 205 of the second fastener 203 is tightly engaged in the slot 102, thus completing the locking of the box body and the lid. When it is necessary to release the locking of the box body and the lid, rotate the first fastener 202 so that the latch 206 of the first fastener 202 leaves the latch 205. During the rotation of the first fastener 202, the second fastener 203 moves relative to the first fastener 202, thereby releasing the tight connection between the hook 207 of the second fastener 203 and the slot 102. Then rotate the second fastener 203 so that the hook 207 is completely separated from the slot 102, thus releasing the locking of the box body and the lid.

[0024] In one specific embodiment, the lid is hinged to the body, allowing the lid to rotate to open or close the body; a lock seat 101 is mounted on the free end of the lid; a fixing plate 201 is mounted on the side of the body; when the lid rotates to close the body, the slot 102 aligns with the fixing plate 201, so that when the second fastener 203 rotates relative to the first fastener 202, the hook 207 can engage with the slot 102. Specifically, in this embodiment, both the fixing plate 201 and the lock seat 101 are fixedly mounted on the side of the body and the free end of the lid respectively via connecting posts A.

[0025] In one specific embodiment, the first fastener 202 has a first mounting groove 208 at its first end; the fixing seat 204 is installed in the first mounting groove 208 and is rotatably connected to the first mounting groove 208 through the first rotating shaft 210, so that the first fastener 202 can rotate relative to the fixing seat 204.

[0026] In one specific embodiment, the first end of the second fastener 203 is provided with a second mounting groove 209; the first end of the first fastener 202 is installed in the second mounting groove 209 and is rotatably connected to the second mounting groove through the second rotating shaft 211, so that the second fastener 203 can rotate relative to the first end of the first fastener 202. Specifically, the inner wall of the first mounting groove 208 is provided with a first mounting hole for mounting the first rotating shaft 210. The first rotating shaft 210 is mounted in the first mounting hole and rotatably connected to the fixed base 204. The inner wall of the second mounting groove 209 is provided with a second mounting hole for mounting the second rotating shaft 211. The second rotating shaft 211 is mounted in the second mounting hole and rotatably connected to the first fastener 202. Further, the first rotating shaft 210 and the second rotating shaft 211 are on different mounting axes. The first rotating shaft 210 is mounted at the end of the first end of the first fastener 202, and the second rotating shaft 211 is mounted on one side of the first rotating shaft 210, so that when the first fastener 202 rotates relative to the fixed base 204 via the first rotating shaft 210, the second fastener 203 can be driven to move relative to it via the second rotating shaft 211. Further, both the first rotating shaft 210 and the second rotating shaft 211 are pivot pins.

[0027] The locking structure disclosed in this utility model, through the arrangement of the first locking component 10 and the second locking component 20, provides a convenient and efficient operating experience. The opening and closing action of the lock is easier and smoother. Users can quickly lock or unlock the box body and lid without applying excessive force or performing complicated operating steps, greatly improving the efficiency of use and conforming to the design concept of humanized operation. At the same time, due to the linkage of the first fastener 202 and the second fastener 203 during use, the force on the lock is evenly distributed during operation, effectively avoiding local stress and greatly enhancing the overall structural strength of the lock. This allows it to maintain a stable working state even under long-term use or when subjected to large external forces, significantly extending its service life and reducing costs. The probability of failure due to structural damage is low. Furthermore, the locking structure design is highly flexible and adjustable. By specifically adjusting the size, shape, and connection method of each component, it can easily adapt to different equipment specifications and usage scenarios. Whether in industrial equipment, daily necessities, or other fields requiring locking functions, it demonstrates excellent applicability, expanding the product's application range. Moreover, the components are connected by pivot pins, allowing for quick positioning and assembly during installation and easy separation of components during disassembly. In later maintenance, specific components can be directly inspected, repaired, or replaced without large-scale disassembly of the entire locking system, effectively reducing maintenance costs and time.

[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
