Publication number: 20240084621Abstract: A security lock has a fixing element and at least one hook. The fixing element is mounted in a security slot of an electronic device. The hook is capable of moving axially with respect to the fixing element, and the hook moves radially outward along a guiding structure of the fixing element to engage with the security slot, the fixing element stays static, i.e., without moving and rotating as the hook is moving. Therefore, the security lock won't press the security slot, and further prevents damage to the security slot caused by frequently or constantly loaded with the security lock. Furthermore, without moving and rotating in a mounting process of the security lock, the fixing element holds the hook to steadily engage with the security slot, and thus an overall anti-pulling and anti-pushing performances are enhanced.Type: ApplicationFiled: July 17, 2023Publication date: March 14, 2024Inventors: Chien-Hung WU, Chia-Hung WANG
