Embodiment Construction

[0015] Make each component of the present invention according to each accompanying drawing, and assemble. What needs to be emphasized here is that several "L" shaped marble slots 5 are excavated on one side of the lock cylinder 2, and several "L" shaped pins 3 are assembled in the "L" shaped pin slots 5. Assemble " L " shape pin spring 4 in the spring embedding hole 3-2 of shape pin pin 3 top; Cut angle flange pin pin hole 11 in the middle part of lock core 2 namely " L " shape pin slot hole 5 , at angle Several angle flange pins 12 are packed into the flange pin holes 11. Here " L " shape marble 3 and angle flange marble 12 are arranged alternately and staggered, as attached Figure 8 shown. Drill a safety comb groove 8 at the rear side of the "L" shape marble slot hole 5, and assemble a safety comb 6 in the safety comb groove 8. Excavate keyway 15 at the bottom of angle flange pinhole 11. And put the matching angle flange pin 12, "L" shaped pin 3 and safety comb 6 into t...

Abstract

The invention relates to a high-safety angle locking cam and a key, and belongs to manufacturing technology of hardware locks. A set of L-shaped marbles and a set of angle flange marbles are assembled in a lock core, and the two rows of the marbles are arrayed at intervals. The lateral surfaces of the two rows of the marbles are assembled with safety combs which are provided with bolts and steps, and each L-shaped marble is provided with a cylinder head which is matched with a wave groove of the key, so that the safety combs are simultaneously matched with the L-shaped marbles and the angle flange marbles. The locking cam and the key have the advantages of novel design, compact structure, accurate assembly and high safety. The invention comprises the key (1), the lock core (2), an angle toothed groove (14), and the like, and is characterized in that one side of the lock core (2) is assembled with the L-shaped marbles (3); one side of the L-shaped marbles (3) is connected with the safety combs (6); convex steps (6-2) of the safety combs are embedded into a press-in groove (19) on one side of the L-shaped marbles (3); and the safety comb bolt (16) is embedded in a safety comb bolt inserting hole (13) of the angle flange marbles (12).
