Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to an electronic lock and a storage cabinet. Background Art

[0002] The locker is provided with an electronic lock and a lock catch, wherein the lock catch is mounted on the cabinet door and the electronic lock is mounted on the cabinet body. The electronic lock includes a housing, a lock hook and an electromagnet. The housing is provided with a notch for the lock catch to enter and exit. The lock hook is rotatably mounted in the housing and can rotate relative to the housing to have a locked position in which it is engaged with the lock catch and an unlocked position in which it is disengaged from the lock catch. The electromagnet is used to drive the lock hook to unlock. When the cabinet door needs to be opened, the electromagnet is energized and the lock hook rotates from the locked position to the unlocked position. In order to prevent the cabinet door from being unable to be opened due to abnormal power failure of the electronic lock, existing electronic locks are usually provided with an emergency unlocking structure. Chinese patent CN204186163U discloses an electronic lock that is provided with an emergency unlocking hole at the point where the clamping and slider integrated block and the block are linked, and a lever is provided at the end of the block adjacent to the emergency unlocking hole. When the power is unexpectedly cut off or the electromagnet fails, the lever separates the clamping and slider integrated block and the block, thereby achieving the purpose of unlocking. Since the stopper is usually machined from a metal material, setting a lever on the stopper requires riveting or welding processes, so the electronic lock in the related art has the problem of complex parts processing.

In the embodiment, the connecting frame 403 of the lock catch 400 is fixedly connected with the cabinet door 200, and the second end of the top rod 325 can abut against the connecting frame 403, which is equivalent to abutting against the cabinet door 200.

[0046] The top rod 352 has an initial position (see Figure 5 ) and a pressed position (see Figure 4), the elastic element 353 is connected between the housing 303 and the top rod 352, the elastic force of the elastic element 353 makes the top rod 352 always have a tendency to move to the initial position, and the top rod position detection sensor 354 can cooperate or separate with the top rod 352. Specifically, when the cabinet door 200 is in the closed position and the lock hook 301 is in the locked position, the cabinet door 200 presses the top rod 352 to make the top rod 352 in the pressed position against the elastic force of the elastic element 353, at this time, the top rod 352 cooperates with the top rod position detection sensor 354, and the top rod position detection sensor 354 outputs a first signal (such as high level), when it is needed to open the cabinet door 200, the electromagnet 305 drives the lock hook 301 to be unlocked to make the lock catch 400 separate from the lock hook 301, the elastic element 353 drives the top rod 352 to move to the initial position and push the cabinet door 200 to automatically pop open, when the cabinet door 200 is opened, the top rod 352 is in the initial position, at this time, the top rod 352 separates from the top rod position detection sensor 354, and the top rod position detection sensor 354 outputs a second signal (such as low level). When the controller of the storage cabinet 010 detects that the output signal of the top rod position detection sensor 354 changes from the first signal to the second signal, it is determined that the cabinet door 200 is opened. In this way, when the temperature is too low due to rainy and snowy weather, the cabinet door 200 and the cabinet body 100 may be frozen together, and the lock hook 301 may be unlocked but the cabinet door 200 cannot be normally opened, therefore, the position of the top rod 352 is detected by the top rod position detection sensor 354, which can accurately determine whether the cabinet door 200 is in the opened position or the closed position.
