Embodiment Construction

[0024] The present invention is a kind of lock cylinder, as figure 1 , 2 As shown, it includes a lock case 1, a lock cylinder 2, and several groups of marble assemblies 3 arranged in them, wherein each group of marble assemblies 3 includes sealing beads 31, springs 32, flat beads 33 and marbles in turn. 34. The length of the marble depends on the corresponding key. Here, the lock cylinder 2 has a row of side bead holes 22 on the side of the bead hole 21, which are respectively used to place the respective side bead 4, between each corresponding bead 34 and the front of the side bead 4 through a buckle The structure 5 is fastened together, so that each marble 34 and the side beads 4 are linked, so that the marbles drive the side beads up and down when sliding up and down; The transverse piece groove 23 toward the side bead hole 22; the back side of the side bead 4 is provided with several gaps 41 that can slide into the transverse piece 6 when the side bead 4 slides up and do...

Abstract

The invention relates to a lock core, which comprises a lock casing, a lock liner and a plurality of groups of bead assemblies arranged between the lock casing and the lock liner. Each group of bead assembly sequentially comprises a sealing bead, a spring, a flat bead and an elastic bead; the lock liner is also provided with a row of lateral bead holes for holding respective lateral beads at a side of a bead hole; each elastic bead and the front surface of the corresponding lateral bead are fastened together by a fastener structure; transverse sheet grooves for holding transverse sheets and communicating to the lateral bead holes are disposed at a side of the lock liner; gaps capable of sliding into the transverse sheets when the lateral beads slide up and down are arranged on the back surfaces of the lateral beads; and transverse sheet springs for facilitating notches of the transverse sheets to slide into transverse sheet limiting grooves of the lock casing are arranged in the transverse sheet grooves at the both ends of the transverse sheets. The lock core is rational in structure, higher in burglary prevention performance and wide in range of application.

Description

【Technical field】 [0001] The invention relates to a lock cylinder. 【Background technique】 [0002] At present, the mechanical management lock cylinder has a structure of upper and lower pins, and the supplementary beads are managed in layers, so that the thief can first apply a rotational force to the lock cylinder when performing technical opening, so that the flat beads are pressed to the side, and then they can be used again. The precision error of machining opens the marbles one by one. When all the marbles are on the same plane, the lock cylinder can be opened, thus opening the whole lock for theft. It can be seen from the above that the current mechanical management lock is only convenient to use, but cannot prevent technical opening, and its anti-theft performance is extremely low. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a lock cylinder with reasonable structure and higher ant...
