Fabricated key for mechanical lock and production process thereof

Abstract

The invention discloses a fabricated key for a mechanical lock, which is characterized in that: the fabricated key is provided with a plurality of tooth bases (2, 3, 4, 5, 6) of which the centers are provided with through holes, and a screw (7); a key handle (1) is provided with a nut (8); the same axial section of the tooth bases (2, 3, 4, 5, 6) is provided with a plurality of tooth positions indifferent directions; and the plurality of tooth bases (2, 3, 4, 5, 6) pass through the center through holes of the tooth bases (2, 3, 4, 5, 6) through the screw (7) and is in threaded connection with the nut (8) positioned on the key handle (1). In the fabricated key, tooth height is standardized, serialized and normalized, ball size matched with the tooth height is standardized, serialized and normalized with the tooth height, and lock parts such as an inner lock core, an outer lock core and the like are standardized, serialized and normalized so as to drive the manufacture of the whole lock to be standardized, serialized and normalized.

Description

technical field [0001] The invention relates to a mechanical tumbler lock, in particular to an assembled key for a mechanical lock and a production process. Background technique [0002] The current mechanical lock manufacturing industry has developed into a modern industry, but due to the individual requirements of the keys matching the locks, the key manufacturing technology is still in the workshop stage, which restricts the modernization process of the entire lock industry. The matching keys of existing mechanical locks are mostly as Figure 1 As shown, it includes a key handle and a plurality of teeth connected with it. The difference in height of these teeth corresponds to different marbles, so that the safety function of "opening a lock with one key" is exerted. Combining several tooth bases together, the tooth heights of each tooth base in the same tooth position are different, forming a tooth shape with ups and downs. Flat keys have one row of teeth, and cross-shap...

Problems solved by technology

However, due to its low security, the cross-shaped key is widely used at present, and the preparation of the cross-shaped key is difficult.

[0003] On the other hand, in the prior art, mechanical coded locks and electronic coded keys have already existed, but their structures are relatively complicated, troublesome to manufacture, high in cost, not very safe, and inconvenient to use. promotional use
