Technical realization elements of marble lock cylinder

Technical realization elements:

7. The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a pinball lock cylinder with different key hole shapes, which can effectively prevent the pinball lock cylinder from being pried.

8. The technical scheme of the present utility model: a marble lock cylinder, comprising a lock cylinder sleeve, a lock cylinder rotating inside the lock cylinder sleeve, and at least two groups of first bullet holes are provided on the outer circumference of the lock cylinder sleeve, and the first bullet holes in each group The first bullet holes are distributed along the axis of the lock cylinder sleeve. The lock cylinder is provided with a number of second bullet holes corresponding to the first bullet holes. A spring that slides the pin toward the lock cylinder, the second pin is slid in the second pin hole, and the lock cylinder is provided with a coaxial first key hole, characterized in that the lock cylinder is provided with a plurality of second key holes , A plurality of second keyholes are distributed on the outer periphery of the first keyhole, and a plurality of second keyholes are connected and arranged with the first keyhole, and the axes of the plurality of second keyholes are arranged in parallel with the axis of the first keyhole, The plurality of second bullet holes are all connected to the plurality of second key holes, and the end of the second bullet away from the lock core sleeve is located in the second key hole.

9. With the above technical solution, since the second bullet hole is connected to the second keyhole, and the second bullet is located in the second keyhole, there are multiple second keyholes. Therefore, the bullet lock cylinder can be avoided. Lock picking, and the combination of multiple second key holes and the first key hole makes the key inserted into the pinball lock cylinder different from the existing key, which can prevent the universal key on the market from being inserted into the key hole of the pinball lock cylinder .

10. A further arrangement of the present utility model: the second keyway is a square channel, two adjacent second keyways are arranged perpendicular to each other, and a plurality of second keyways can be arranged in a square shape.

11. With the above further arrangement, it is convenient to open the second key hole and the first key hole on the lock cylinder. The second key hole is a square hole. Therefore, the blade on the key inserted into the second key hole is square, which can avoid the market The upper master key is inserted into the key hole of the marble lock cylinder, which also reduces production costs and improves economic benefits.

12. A further arrangement of the present utility model: the second key hole is an arc-shaped hole.

13. With the above further arrangement, the blade on the key inserted into the second key hole is arc-shaped. Since one end of the second pin is located in the second key hole, the key slot on the key is located on the arc blade, Therefore, the master key on the market cannot be inserted into the key hole of the pin cylinder to unlock.

14. The present utility model has a further arrangement: the communication between the second keyhole and the first keyhole is in a square shape, and the second keyhole and the communication form an "l"-shaped configuration.

15. With the above-mentioned further arrangement, the key hole of the pinball lock cylinder is provided with ribs, which further prevents the pinch lock cylinder from being unlocked by technology, and also facilitates the production of the first key hole, the second key hole and the connecting point of the lock cylinder. And to produce keys that can be inserted into the first keyway and the second keyway at the same time, reducing production costs and improving economic benefits.
