Abstract

The utility model relates to a bead lock with side columns and a key, wherein the bead lock comprises a locking head, a lock pin, a surface bead, a bottom bead, springs and a bead sealing piece, plural square holes which are arranged in a straight line are arranged beside the bead hole of the lock pin, each square hole is provided inside with a moving card, the lower end of each square hole is communicated with a key groove, one side of each square hole is provided with a groove getting through the lock pin, the locking head adjacent to the lock pin is provided with trigone grooves which are corresponding to the lock pin grooves, each lock pin groove is provided inside with a side column, and one side of each side column is embedded in the corresponding trigone groove. The key matching the lock pin comprises front key teeth, and one side of the key is provided with a bent snake-shaped groove. Because the bead lock with side columns is doubly locked by the side columns and the beads, the lock can be unlocked only by simultaneously unlocking the locking of the beads and the locking of the side columns, and thereby the lock can not be unlocked by master keys and is high in safety.

Description

The cylinder lock with balls and the key that have lateral column

Technical field

The utility model relates to a kind of cylinder lock with balls, the especially a kind of cylinder lock with balls of lateral column and key that matches of having.

Background technology

The cylinder lock with balls that generally uses is generally the structure of monolateral lock core at present, promptly on the spoon tooth position with respect to the insertion key front hoodle is being housed on the lock core.The major defect of this monolateral lock core be stirred by master key easily and make the lock open, theftproof performance is poor.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of cylinder lock with balls and key that has lateral column, and this cylinder lock with balls that has lateral column can lock lock core by lateral column, loses rotatory force when making master key stir hoodle, lock can't be opened, improve the theftproof performance of lock greatly.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of cylinder lock with balls that has lateral column, comprise tapered end, lock core, the face pearl, end pearl, spring and bead sealing piece, next door, hoodle hole at lock core is provided with arrangement several square openings in line, be respectively equipped with active card in the square opening, the lower end of square opening communicates with key, pass lock core in a side of square opening and be provided with a groove, on the tapered end adjacent, be provided with the triangular groove with lock core, lock core groove is corresponding with the triangular groove of tapered end, one lateral column is installed in lock core groove, and lateral column one side embeds the triangular groove of tapered end.

Described active card is positioned at lateral column one end can be provided with the groove that cooperates with lateral column, and active card is positioned at key one end can be provided with socket cap.

The two ends of described lateral column can be respectively equipped with spring.

A kind of key that is used with the cylinder lock with balls that has a lateral column comprises positive spoon tooth, is shaped on the groove that the socket cap on the active card with lock core matches on the side of key.

The beneficial effects of the utility model are, this cylinder lock with balls that has lateral column is to set up lateral column at the lock core side, lateral column locks lock core, because this cylinder lock with balls that has lateral column is by hoodle and lateral column double locking, when opening lock, must untie this two kinds of lockings simultaneously, thereby master key (omnipotent key) can't be opened, safety is high.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is described in detail:

With reference to figure 1, Fig. 2, shown in Figure 3, the utility model has the cylinder lock with balls of lateral column, comprise tapered end 2, lock core 1, face pearl 5, end pearl 6, spring 4 and bead sealing piece 3, on tapered end 2, be provided with the hoodle hole 16 that 6 yi word patterns are arranged, hoodle hole 16 passes in the key after outside in passing the outer wall of tapered end 2 and lock core 1, spring 4 is housed in the hoodle hole 16, face pearl 5 and end pearl 6, the hole of bead 16 outer bead sealing pieces 3 that are provided with, be provided with arrangement 5 square openings 7 in line on 16 next doors, hoodle hole of lock core 1, be respectively equipped with active card 8 in the square opening 7, the lower end of square opening 7 communicates with key, pass lock core in a side of square opening 7 and be provided with a groove 17, be provided with triangular groove 12 on the tapered end 2 adjacent with lock core 1, lock core groove 17 is corresponding with the triangular groove 12 of tapered end, is provided with a lateral column 11 in lock core groove 17.With reference to figure 4, shown in Figure 5, the two ends of lateral column 11 respectively are provided with spring 15, and the side of lateral column 11 is tapered, embed in the triangular groove 12 of tapered end, and another side of lateral column 11 is close to the active card 8 in the square opening 7.With reference to shown in Figure 6, active card 8 is positioned at lateral column one end and is provided with groove 10, and active card 8 is positioned at key one end can be provided with socket cap 9.With reference to shown in Figure 7, have the key 13 that the cylinder lock with balls of lateral column is used with the utility model, not only comprise positive spoon tooth, also be included in and be shaped on a groove 14 that is bent into the snake type on the side.Still with reference to figure 3, lateral column 11 is fixed on groove 12 by active card 8, and the side of lateral column 11 is stuck in the triangular groove 12 of tapered end 2, and lock core 1 can't be rotated.With reference to figure 1, Fig. 8, the spoon tooth cooperates with hoodle, the socket cap 9 of active card 8 slips in the snake type groove 14, and being separately fixed at the diverse location place, the groove 10 that makes active card 8 be positioned at lateral column one end is in-line, key 13, lateral column can fall in the groove 10, lock core 1 is rotated, thereby make lateral column cooperate unlatching simultaneously, lock is opened with hoodle.

Simultaneously, select because hoodle has several length, the groove on the active card also has a plurality of diverse location combinations, and hoodle is combined with active card, can organize millions of key numbers, makes the mutual opening rate of this cylinder lock with balls that has lateral column extremely low.
