Embodiment

[0018] Example: such as figure 1 , figure 2 As shown, a key guide device for a lock, the upper end face of the funnel-type guide hole groove (1) is round and the lower end face is provided with an orientation hole groove (2), and the funnel-type guide hole groove (1) is continuous from top to bottom become smaller, and at the same time, the left and right sides are symmetrically and continuously narrowed until it is smoothly transitioned to the directional hole groove (2). ) The shape and size of the orifice are consistent.

[0019] The lower end of the orientation hole (2) is tightly fitted with the inner diameter of the bearing (3) and welded together.

[0020] The outer diameter of the bearing (3) is closely matched with the inner diameter of the lower end of the round tube (9), and they are welded together. The upper end of the round tube (9) is flush with the upper end surface of the funnel-type guide hole groove (1), and the funnel-type guide hole Groove (1) can rot...

Abstract

The invention discloses a key guide device of a lock. The device is provided with a funnel-shaped guide slotted hole, a directional slotted hole, a bearing, a round tube and a double-faced adhesive ring. After the anti-sticking paper of the double-faced adhesive ring is peeled off, the double-faced adhesive ring is glued to the outer edge of the top of a lock core as being aligned to the axis of the lock core. The key is inserted into the funnel-shaped guide slotted hole and the directional slotted hole and can be easily inserted into the key hole as being guided by the funnel-shaped guide slotted hole and directed by the directional slotted hole. Next, the key is turned to open the lock easily. The device has the key guide function and is used for solving the technical defects of the existing locks, for example, difficult alignment to the key holes at night or in dark places and for the old people and the blind to open the lock by using keys.
