[0029] Please refer to Figure 1 and Figure 5 The present application discloses a lock for realizing interlocking and unlocking between a box body and a box lid in a storage box. The lock includes a lock body 100, a lock connecting rod 200, an elastic member 300 and a lock bracket 400. The lock bracket 400 is arranged on the box body, and both ends of the lock connecting rod 200 are fixed on the lock bracket 400. The lock body 100 and the elastic member 300 are movably mounted on the lock connecting rod 200, and the two ends of the elastic member 300 respectively abut against the lock body 100 and the lock bracket 400, for pressing against the lock body 100 to engage the lock body 100 with the box lid, so as to interlock the box body and the box lid.

[0030] In this embodiment, a latch bracket 400 is positioned at the edge of one side of the box body. A snap-fit portion is provided at each end of the latch connecting rod 200. After the latch body 100 and the elastic member 300 pass through the latch connecting rod 200, the snap-fit portion secures the latch connecting rod 200, the latch body 100, and the elastic member 300 to the latch bracket 400. The latch connecting rod 200, the latch body 100, and the elastic member 300 cooperate to achieve interlocking between the box body and the lid. The elastic member 300 can be a variety of elastic elements, such as a spring or elastic rubber.

[0031] Please refer to Figure 2 and Figure 6 When the latch body 100 is driven by an external force and moves to a preset unlocking position on the latch bracket 400, the latch body 100 separates from the box lid, unlocking the box body and the box lid. Specifically, in the default state, the elastic member 300 applies a supporting elastic force to the latch body 100, causing the latch body 100 to engage with the box lid. At this time, the box body and the box lid are interlocked. The position of the latch body 100 in this state is referred to as the interlocking position. By applying an external force to the latch body 100, the latch body 100 is moved from the interlocking position to the unlocking position, and the latch body 100 and the box lid are disconnected, thereby unlocking the box body and the box lid.

[0032] Please refer to Figure 1 and Figure 5 In this embodiment, the latch bracket 400 includes a first bracket portion 4010 and a second bracket portion 4020, which are spaced apart. One end of the elastic member 300 abuts against the latch body 100, while the other end abuts against the second bracket portion 4020. Specifically, the first bracket portion 4010 and the second bracket portion 4020 are arc-shaped cylindrical structures, each with a perforated hole in the middle. Meanwhile, the elastic member 300 is disposed between the latch body 100 and the second bracket portion 4020.

[0033] Please refer to Figure 1 and Figure 3In this embodiment, the latch body 100 is provided with a through hole 1010, through which the latch connecting rod 200 passes, with its ends respectively fixed to the first bracket portion 4010 and the second bracket portion 4020. Specifically, the engaging portion 1020 of the latch connecting rod 200 passes through the holes in the first bracket portion 4010 and the second bracket portion 4020, with its ends respectively engaged with the first bracket portion 4010 and the second bracket portion 4020, thereby fixing the latch connecting rod 200 relative to the latch bracket 400.

[0034] Please refer to Figure 5 and Figure 6 In this embodiment, the first bracket portion 4010 is provided with an engaging portion 4011, and the latch body 100 is provided with a locking portion 1020 corresponding to the engaging portion 4011. The elastic member 300 is pressed between the second bracket portion 4020 and the latch body 100, and the elastic force of the elastic member 300 pushes the locking portion 1020 into engagement with the engaging portion 4011. Specifically, the engaging portion 4011 is provided on one side of the first bracket portion 4010, and the locking portion 1020 is provided at the outer edge of the through hole 1010 of the latch body 100. The engaging portion 4011 and the locking portion 1020 are hook-shaped structures that fit together. When the latch body 100 is in the interlocked position, the supporting elastic force of the elastic member 300 pushes the locking portion 1020 of the latch body 100 into engagement with the engaging portion 4011 of the first bracket portion 4010, locking the locking portion.

[0035] Please refer to Figure 2 and Figure 4 In this embodiment, the lock body 100 is further provided with a fastening portion 1030 for engaging with the box cover. The box body is provided with a displacement hole. The fastening portion 1030 of the lock body 100 passes through the displacement hole and is rotatably and movably sleeved on the lock connecting rod 200. Specifically, the fastening portion 1030 is provided at the upper end of the through hole 1010 of the lock body 100 and is a hook-type structure. In one embodiment, a displacement hole is provided on the box body to enable the lock body 100 to move and rotate on the lock connecting rod 200. A docking portion (999) is provided on the box cover, and the fastening portion 1030 of the lock body 100 can be engaged with the docking portion (999) of the box cover after passing through the displacement hole.

[0036] In this embodiment, when the box body and the lid are interlocked, the buckle portion 1030 of the lock body 100 engages with the lid, and the locking portion 1020 engages with the bite portion 4011 of the first bracket portion 4010. Specifically, under the supporting elastic force of the elastic member 300, the lock body 100 is pushed to the first bracket portion 4010, so that the locking portion 1020 of the lock body 100 engages with the bite portion 4011 of the first bracket portion 4010. At the same time, the buckle portion 1030 of the lock body 100 engages with the lid, achieving a double interlocking of the box body and the lid, and improving the overall locking stability of the storage box.

[0037] When the lock body 100 is in the unlocked position, the fastening portion 1030 of the lock body 100 is separated from the box cover, and the locking portion 1020 is removed from the bite portion 4011 of the first bracket portion 4010, thereby unlocking the box body and the box cover. Specifically, a force is applied to the lock body 100 in the direction of the second bracket portion 4020, so that the lock body 100 compresses the elastic member 300 and rotates around the lock connecting rod 200, thereby simultaneously achieving the removal of the locking portion 1020 of the lock body 100 from the bite portion 4011 of the first bracket portion 4010 and the separation of the fastening portion 1030 of the lock body 100 from the box cover, thereby unlocking the box body and the box cover. On the other hand, if the box body and the box cover are to be restored to the interlocked state, it is only necessary to cancel the external force applied to the lock body 100, so that the elastic potential energy accumulated when the elastic part 300 is compressed can be converted into kinetic energy, and the lock body 100 can be pushed back toward the direction of the first bracket part 4010, thereby realizing the interlocking of the box body and the box cover. The steps are simple and easy to operate.

[0038] In this embodiment, the lock body 100 is further provided with an anti-slip groove 1040, and a friction strip 1041 is provided in the anti-slip groove 1040. Specifically, the anti-slip groove 1040 is provided on the outer wall of the through hole 1010 of the lock body 100. In one embodiment, the number of the anti-slip grooves 1040 is two, and they are spaced apart. Among them, the anti-slip groove 1040 is further provided with a friction strip 1041 arranged in the vertical direction. In one embodiment, the number of the friction strips 1041 provided in the anti-slip groove 1040 is three. In actual use, in some cases, it may be inconvenient for the user to directly apply an external force to the lock body 100 to achieve unlocking. In this case, the user can choose to place two fingers on the friction strip 1041 of the anti-slip groove 1040, and use the fingers to apply a force along the direction of the second bracket part 4020 to the lock body 100, thereby achieving unlocking of the box body and the box lid.

[0039] In this embodiment, the buckle portion 1030 of the lock body 100 is provided with an auxiliary hole 1031 along the thickness direction. This is used to apply an external force to the inner wall of the auxiliary hole 1031 to unlock the box body and the box lid when the elastic member 300 fails. Specifically, due to the fatigue limit of the elastic member 300, it may be impossible to directly apply an external force to the lock body 100 to unlock the box body and the box lid during actual use due to the failure of the elastic member 300. Therefore, the auxiliary hole 1031 is provided in the buckle portion 1030 of the lock body 100 to avoid this situation. In one embodiment, the auxiliary hole 1031 is provided on the buckle portion 1030 of the lock body 100 and has an elliptical structure. The user can use an object such as a screwdriver, pen, or key to apply an external force to the inner wall of the auxiliary hole 1031 in the direction of the second bracket portion 4020 to unlock the box body and the box lid.

[0040] In this embodiment, a pressing portion 1050 is further provided at the other end of the lock body 100 opposite the locking portion 1030. This pressing portion 1050 is used to apply an external force to the lock body 100 to drive the lock body 100 to move relative to the lock bracket 200. Specifically, the pressing portion 1050 is located at the lower end of the through hole 1010 of the lock body 100 and has a rectangular structure. In actual use, the user can pinch the pressing portion 1050 with their fingers and apply an external force to the lock body 100 in the direction of the second bracket portion 4020, thereby unlocking the box body and the box lid.

[0041] The present application also discloses a storage box, comprising a box body, a box lid and a lock as described above, wherein the lock bracket of the lock is mounted on the box body, and the lock body is used to detachably engage with the box lid to form interlocking and unlocking between the box body and the box lid.

[0042] In this embodiment, one side of the box body is concave to form a lock mounting portion, and a lock receiving groove is provided on the lock mounting portion. When the box body and the box cover are interlocked, the lock receiving groove is used to limit the buckling portion 1030 of the lock body 100.

[0043] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the appended claims.
