Description

Technical Field

[0001] This invention belongs to the field of lock cylinder technology, and in particular relates to a suspended ball lock cylinder. Background Technology

[0002] The anti-theft capability of existing lock cylinders mainly relies on the interaction between the pin mechanism and the key's tumbler mechanism. Experienced lock pickers can easily replace the key with tools, making the anti-theft capability insufficient. Increasing the number of tumbler engagement points is one way to improve the anti-theft capability of lock cylinders. However, due to the limited length of the lock cylinder, it is not possible to effectively increase the number of pin mechanisms in a single row. If pin mechanisms with different angles are set, the lock shell only has a single pin assembly, and the rest of the lock shell is a thin-walled structure. Due to the limitations of structural space, this is not conducive to the design, production, and installation of the pin mechanism.

[0003] Therefore, designing a lock cylinder that is easy to process, manufacture, and assemble, and that can increase the number of toothed engagement points and different directions is a problem that needs to be solved by those working in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a floating ball lock cylinder. Through the design of the secondary pin mechanism and the floating block on the key, the number of embossed mating points can be increased. At the same time, the secondary pin mechanism and the main pin mechanism have different directions, which can increase the different angles of the embossed mating points, greatly improving the anti-theft capability of the lock cylinder. Moreover, the secondary pin mechanism will not interfere with the lock shell, which is beneficial to processing, production and assembly.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0011] The two suspension ports have clearance notches at the edges of the ends away from the key flower part, and both ends of the suspension block have square cone-shaped cone heads.

[0012] Furthermore, the lock housing includes a bead-filling part and two cylinder-filling parts, with the two cylinders rotatably disposed within the two cylinder-filling parts respectively, and a clutch and a dial are provided between the opposite ends of the two cylinders.

[0013] Furthermore, the bead-filling part has two rows of ball holes linearly opened on it, and the two rows of ball holes are respectively connected to the two insert parts.

[0014] Furthermore, the main ball mechanism includes a main end, a main spring, a connecting head, and a main ball head. The main end is fixed to the inner end of the ball hole, the connecting head is slidably disposed in the ball hole, the main spring is disposed between the main end and the connecting head, and the main ball head is slidably disposed in the main port.

[0015] Furthermore, guide edges are provided on both inner side walls of the keyhole, and inner guide grooves that mate with the guide edges are provided on the upper and lower surfaces of the key body. The inner guide grooves are misaligned with the key flower part on the key body.

[0016] Furthermore, an outer guide edge is provided at the outer edge of the keyhole, and an outer guide groove is provided on both the upper and lower surfaces of the key body to cooperate with the outer guide edge. A notch is provided on the cone head of the suspended block away from the key flower part, which is linearly distributed with the outer guide groove.
