[0002] Prison vans are an important means of transportation in judicial proceedings.
[0003] The main function of existing technologies such as prison van locks is to ensure that criminal suspects cannot move freely during the escort process. By locking the cell where the suspect is located or the restraints on his hands and feet, it is possible to effectively prevent them from walking around in the car, escaping, or attacking the escorting personnel. For example, in the prison van, there are special handcuffs and shackles connected to the prison van locks, which limit the suspect's range of movement to a very small space, ensuring the basic order of the escort process, and the cage is usually closed with a single lock technology, which can be easily opened from the inside when it is severely damaged.
[0004] In order to solve the problem of cage locks, special keys are usually required to open and close them. During the escort process, key storage is crucial, but it is also easy to cause problems. For example, the key may be lost, damaged, or snatched by the prisoners. Moreover, different prisoner car cage locks may require different keys. During large-scale escort operations or vehicle deployment, key management and matching will become very complicated, which needs to be optimized. Utility Model Content
