Embodiment Construction

[0024] The present invention is a lock core, such as figure 1 , 2 As shown, it includes a lock case 1, a lock liner 2, and several sets of marble assemblies 3 arranged in them, wherein each set of marble assemblies 3 includes a sealing ball 31, a spring 32, a flat ball 33 and a marble in turn 34. The length of the marble depends on the corresponding key. Here, the lock cylinder 2 also has a row of side bead holes 22 on the side of the marble hole 21 for placing the respective side beads 4, and a buckle is passed between each corresponding marble 34 and the front side of the side beads 4 The structure 5 is buckled together so that each marble 34 and the side beads 4 are linked, so that when the marbles slide up and down, they drive the side beads up and down; on the side of the lock cylinder 2 is opened for placing the cross piece 6, and Toward the horizontal piece groove 23 of the side bead hole 22; on the back of the side bead 22, there are several notches 41 that can slide in...

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 core. 【Background technique】 [0002] At this stage, the mechanical management lock cylinder is a structure of upper and lower rows of marbles, and bead-filled layered management, so that the thief can first apply a rotating force to the lock cylinder when opening technically, so that the flat bead will be pressed to the side, and then reused The precision error of machining opens the marbles one by one. When all the marbles are in the same plane, the lock cylinder can be opened, thus opening the entire 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 the invention] [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a lock cylinder with reasonable structure and higher anti-theft performance. [0004] In or...
