[0041] Reference Figures 1 to 3 , a lock, including a lock hook assembly and a lock seat.

[0042] The lock hook assembly and the lock seat (the lock seat is not shown in the figure) are respectively fixedly installed on two structures that can be separated or movably connected to each other. Here, a storage box is taken as an example. In this embodiment, the lock seat is fixedly connected to the box cover by screws, and the lock hook assembly is installed on the box body.

[0043] Specifically, in this embodiment, the lock hook assembly includes: a lock hook seat 100 , a rotating member 200 , a hook member 300 , a locking structure 400 and an elastic member 500 .

[0044] The lock hook seat 100 is fixedly connected to the box body of the storage box by screws.

[0045] The rotating member 200 is rotatably connected to the lock hook seat 100, and the rotating member 200 rotates around the first axis.

[0046] The end of the rotating member 200 away from the first axis (i.e. the end of the rotating member 200 away from the hinge end thereof) is provided with an inclined bending part 210, which extends in a direction away from the storage box. By providing the inclined bending part 210, the operator can bend the rotating member 200 more easily.

[0047] The hook fastener 300 is rotatably connected to the rotating member 200, and the hook fastener 300 rotates around the second axis. A buckling portion 310 is provided at one end of the hook fastener 300 away from the second axis. The buckling portion 310 is used to buckle and connect with the lock seat to lock the box cover and the box body. The second axis is parallel to the first axis and the second axis is spaced apart from the first axis, so that when the operator bends the rotating member 200 to rotate, one end of the hook fastener 300 will be driven to move around a circular arc in a direction close to the lock seat, thereby allowing the hook fastener 300 to be detached from the lock seat.

[0048] The hook fastener 300 is provided with a first limiting portion 320 , and the first limiting portion 320 is a sheet metal bending component.

[0049] The hook fastener 300 is provided with a lock connector 330, and the rotating member 200 is provided with a through hole. The lock connector 330 passes through the rotating member 200 from the through hole and extends in a direction away from the storage box. The end of the lock connector 330 extending out of the rotating member 200 is provided with a lock connecting hole. The lock connector 330 is used to connect with an external lock so that the operator can lock the storage box to prevent others from opening the storage box, thereby improving the safety performance of the lock.

[0050] The locking structure 400 is provided with a second position and a first position arranged along the left and right sides. The locking structure 400 is provided with a control part 410, and the control part 410 is protrudingly arranged on the side of the rotating member 200 (the left side or the right side of the rotating member 200). The operator presses the control part 410 to make the locking structure 400 move along the left and right direction relative to the rotating member 200, so that the locking structure 400 switches between the second position and the first position.

[0051] The locking structure 400 is provided with a second limiting portion 420. When the locking structure 400 is located at the first position, the first limiting portion 320 and the second limiting portion 420 are correspondingly arranged. The first limiting portion 320 limits the position of the second limiting portion 420. The second limiting portion 420 is used to cooperate with the first limiting portion 320 to limit the locking structure 400. By limiting the locking structure 400, the rotation of the rotating member 200 can be limited, thereby ensuring that the lock will not be easily unlocked due to vibration, which is conducive to ensuring the safety of the storage box installed with the lock. When the locking structure 400 is located at the second position, the first limiting portion 320 and the second limiting portion 420 are misaligned. At this time, the operator can bend the rotating member 200 to unlock the lock.

[0052] The locking structure 400 is provided with a position limiting structure 430 protruding therefrom, which is arranged inside the rotating member 200 and is used to cooperate with the inner wall of the rotating member 200 to limit the position of the locking structure 400, thereby preventing the locking structure 400 from being separated from the rotating member 200 after installation.

[0053] Specifically, in this embodiment, the position limiting structure 430 is formed by bending through a stamping process, and the position limiting structure 430 is stamped after the locking structure 400 is installed on the rotating part 200. In other embodiments, the position limiting structure 430 can also be set as a protruding structure fixed by welding. Those skilled in the art can select the formation method of the position limiting structure 430 according to actual needs.

[0054] Specifically, in this embodiment, the control part 410 is configured as a sheet-like structure, and the control part 410 is configured parallel to the side wall of the rotating part 200. By configuring the control part 410 as a sheet-like structure, the contact area between the control part 410 and the operator's finger can be increased, thereby reducing the operator's discomfort when controlling the locking structure 400.

[0055] Specifically, in this embodiment, the locking structure 400 is provided with a guide portion 440, and the number of the guide portions 440 is set to two. The two guide portions 440 are arranged in parallel, and a guide hole is opened on the side wall of the rotating member 200. The guide portion 440 corresponds to and matches the guide hole one by one. The guide portion 440 passes through the guide hole and is slidably connected with the guide hole. By setting the guide portion 440, the locking structure 400 can be guided, thereby preventing the locking structure 400 from deviating during movement and causing the locking structure 400 to fail to work normally, thereby ensuring that the lock can work normally.

[0056] The elastic structure is arranged between the locking structure 400 and the rotating part 200. Specifically, in this embodiment, the elastic structure is arranged as a coil spring. In other embodiments, the elastic structure can also be arranged as other conventional elastic components such as spring sheets. Those skilled in the art can select the elastic structure according to actual needs.

[0057] Specifically, in this embodiment, the elastic structure is sleeved on the guide portion 440, and the two ends of the elastic structure are respectively abutted against the locking structure 400 and the inner wall of the rotating member 200. The guide portion 440 can limit the position of the elastic structure, and there is no need to additionally design a structure to limit the elastic structure, thereby reducing the structural complexity of the lock.

[0058] The elastic structure enables the locking structure 400 to always have a tendency to move from the second position to the first position.

[0059] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
