Abstract
The utility model relates to an electronic lock unable to be unlocked by vibration which aims at the technical problems that an existing product is poor in anti-vibration effect and complex in structure. The electronic lock unable to be unlocked by the vibration is characterized by comprising an anti-vibration mechanism which comprises a gravity part and an elastic part, wherein the gravity part is arranged in a shell body, the sliding direction of the gravity part is parallel to the stretching direction of an movable iron core, and the elastic part is used for sliding and resetting of the gravity part. An interlock part is arranged between the gravity part and the movable iron core. In an initial state, the interlock part is connected with the gravity part, and the interlock part is not linked with the movable iron core. When an outer force which drives the movable iron core to contract and enables the movable iron not to abut against the end portion of a rotating lock tongue acts on the electronic lock unable to be unlocked by the vibration, the moving direction of the gravity part is identical with that of the movable iron core. The gravity part undergoes displacement in advance of the movable iron core, the gravity part is linked with the interlock part, and locking is formed between the interlock part and the movable iron core. The electronic lock unable to be unlocked by the vibration is simple in structure, small in size, good in anti-vibration effect, high in reliability, and suitable for being used as the electronic lock of a safe box (cabinet) or an improvement of products of the same kind.
