Abstract

A covering plate, a covering plate treatment process and a lock with the covering plate are provided and mainly resolve the problem that the existing lock covering plate is complex in production work procedure and high in manufacture cost. The covering plate is characterized by being formed by drawing and reshaping a steel plate, the covering plate is provided with a holding hole, a location portion is arranged on the edge of the holding hole, and the holding hole and the location portion are made by punching and edge turning. The lock covering plate, the covering plate treatment process and the lock with the covering plate reduce production work procedures of the covering plate and reduce production cost of the covering plate.

Description
