Abstract

The invention relates to a key, in particular to a split type key. The split type key comprises a key handle, a left key piece and a right key piece, wherein key grains are respectively formed in the left key piece and the right key piece, a convex ridge is formed on the side surface of the left key piece, a groove is formed in the side surface of the right key piece, the left key piece and the right key piece are spliced into a whole to form an integral key piece through matching of the convex ridge and the groove, a splicing groove is formed in the key handle, and one end of the integral key piece is spliced into the splicing groove in a matching mode. The split type key is divided into the left piece and the right piece, the two key pieces are respectively kept by two persons, a lock cannot be unlocked by using one separate key piece, and the lock can be unlocked only when the two persons keep together to gather the two key pieces together, so as to completely avoid omission on supervision and management. The split type key is convenient for locking and unlocking and favorable for clearly defining authorities of users, and the split type key is favorable for separate management and mutual supervision.

Description

technical field [0001] The invention relates to a key for opening a lock, in particular to a split key in which a key is divided into two parts, left and right, which are combined and used by means of concavo-convex matching. Background technique [0002] The key is usually designed as a whole. As long as the user has the key, he can open the lock alone without the supervision of others. In some occasions that require multi-person management and mutual supervision, this lack of a holistic key to supervision will inevitably lead to omissions in supervision and management. Contents of the invention [0003] The object of the present invention is to invent a split type key that can be stored separately and used together in order to overcome the defect that the existing integral key lacks a supervisory function. [0004] The purpose of the present invention is achieved in the following manner: the split key includes a key handle, a left key blade and a right key blade, the le...
