Description

Technical Field

[0001] The utility model belongs to the technical field of lock cores, and particularly relates to an upper and lower bead lock core. Background Art

[0002] In view of the existing lock core structure, anti-theft can be achieved through the cooperation of the upper pins in the pin mechanism and the tooth pattern on the key. However, most of the existing pin structures are arranged in a single row, and an experienced illegal lock picker can use tools to replace the key, resulting in insufficient anti-theft ability.

[0003] Moreover, this single-row pin structure is arranged on the bead-loading part of the lock shell, and the rest are thin-wall structures, which is not conducive to the arrangement and installation of the remaining pin structures.

[0004] Therefore, designing a lock core that can increase the number of pin mechanisms and tooth patterns is a problem that needs to be solved by those skilled in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an upper and lower bead lock core. By embedding and installing a new sub-pin mechanism in the thin-wall part of the lock shell, the number of tooth patterns of the lock core can be greatly increased by increasing the number of pin mechanisms, achieving a higher level of security and better anti-illegal opening function, and improving the anti-theft ability of the lock core.

The lock cylinder is rotatably arranged in the cylinder-loading part. A plurality of main pin holes are linearly formed on the lock cylinder. The main pin mechanism is arranged between the main through hole and the main pin hole.

[0008] A plurality of sub-through holes are linearly formed on one side of the cylinder-loading part away from the bead-loading part. A plurality of sub-pin holes matched with the sub-through holes are linearly formed on the lock cylinder. The plurality of sub-pin holes and the plurality of main pin holes are respectively located on opposite sides of the lock cylinder and are out of position.

[0009] The sub-pin mechanism includes a sub-end head, a sub-spring and a sub-warhead.

[0010] The sub-end head includes a cover plate and a pressing plate. An outer sleeve is provided at the edge of the cover plate. The cover plate is fixed in the sub-through hole. A folded edge is fixed at the edge of the pressing plate. The pressing plate is slidably arranged in the outer sleeve through the folded edge. The sub-spring is fixed at the position between the pressing plate and the cover plate. The sub-warhead is slidably arranged in the sub-pin hole.

[0011] Further, an installation area is formed on the lock housing at a position between the two bulb mounting parts. A clutch and a dial are provided between the two lock bulbs, and the clutch and the dial are located in the installation area.

[0012] Further, the main pin mechanism includes a main end head, a main spring, a connecting head, and a main bullet head. The main end head is fixed at one end of the main through port away from the lock bulb. The connecting head is slidably arranged in the main through port. The main spring is fixed between the connecting head and the main end head. The main bullet head is slidably arranged in the main pin hole.

[0013] Further, a key body is further included. A main key flower part is provided on one surface of the key body, and the main bullet heads of several main pin mechanisms cooperate with the main key flower part.

[0014] Further, a secondary key flower part is provided on the other surface of the key body, and the secondary bullet heads of several secondary pin mechanisms cooperate with the secondary key flower part.

[0015] Further, a flange is provided on the inner side of one end of the secondary through port close to the lock bulb. The cover plate is fixed in the secondary through port, and the end of the outer sleeve body is attached to the flange.

[0016] The utility model has the following beneficial effects:

[0017] By embedding and installing a new secondary pin mechanism in the thin-walled part of the lock housing, the utility model realizes a substantial increase in the number of keyway patterns of the lock core by increasing the number of pin mechanisms, can achieve a higher level of security and better anti-illegal opening function, improve the anti-theft ability of the lock core, and the designed new secondary pin mechanism has a small length and is suitable for arrangement in a narrow space on the lock housing.

[0018] Of course, any product implementing the utility model does not necessarily need to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
