Method for manufacturing multi-cylinder lock bit

Abstract

The invention discloses a multi-cylinder lock bit, which is characterized in that the inside of a lock bit is provided with a plurality of lock cylinders and a plurality of sets of locking mechanisms; as an example shown in a Figure 4, the lock cylinders (including an outer lock cylinder 3, an upper lock cylinder 4 and a lower lock cylinder 5) of a three-cylinder lock bit are framed and represented by dotted lines; the structure layout drawings of the three-sets of locking mechanisms respectively consisting of the lock cylinders above are as follows: a locking mechanism for the outer lock cylinder is shown in a Figure 9, a locking mechanism for the upper lock cylinder is shown in a Figure 10, and a locking mechanism for the lower lock cylinder is shown in a Figure 11; and a set of lock cylinder (namely, a middle lock cylinder 6 shown in a Figure 5) is added between the upper lock cylinder 4 and the lower lock cylinder 5, then a four-cylinder lock bit is formed. Through carrying out 45-degree staggered arrangement on the key-tooth accommodating grooves of the upper and lower lock cylinders, a state that the locking mechanism of the lower lock cylinder 5 is completely shielded by a metal lock cylinder body of the upper lock cylinder 4 is formed, thereby truly achieving the cylinder-shielding effect of locksets. Compared with common lock bits, the capability of a cylinder-shielded and multi-cylinder lock bit in violent opening and technique countermeasures is incomparable.

Description

technical field [0001] The present invention relates to a lockset, in particular to a lock head, which is a lock head composed of a plurality of lock cores. Background technique [0002] Looking at all mechanical pin-type locks, they are all locking mechanisms composed of a single lock cylinder. Their structure is too simple and their technical content is low. Some of the problems and defects exposed are concentrated in the ability to resist technical confrontation and prevent violent opening. The lack of, so the robbery occurred from time to time. Contents of the invention [0003] The present invention-multi-core lock head is provided with multiple lock cores and multiple sets of locking mechanisms in one lock head, such as Figure 4 In the example shown, each lock core of the three-core lock head is framed by a dotted line: the outer lock core 3, the upper lock core 4 and the lower lock core 5; , the lock core body outer cover 2 and the outer lock core locking pin 10; ...
