Description
Technical field
The utility model relates to lock technology field, especially a kind of lock being provided with key guiding device.
Background technology
The development of modern lock is maked rapid progress, but needs key operated lock still dominate.People are when opening the lock with the key at night or insufficient light place, and key is always difficult to aim at keyhole.Old man and blind person are unblanked difficult especially.
Utility model content
The purpose of this utility model is to provide a kind of lock with key guide function, solves people are difficult to the existing lock aiming at keyhole technological deficiency when night or insufficient light place and old man and key for blind men unblank.
The technical solution of the utility model is: a kind of lock being provided with key guiding device, the upper surface of described lock body is provided with cannelure, the internal diameter of described cannelure is provided with the external screw thread connected with the internal thread of pipe, the top of described pipe and the external diameter tight fit of bearing, and welds together.
The internal diameter of described bearing and the lower end tight fit of directed hole slot, and weld together, the cross section shape and size of described directed hole slot are all consistent with the shape and size in the aperture of the keyhole of lock body.
It is circular funneling guiding hole slot that the upper end end face of described directed hole slot is provided with upper end end face, and described funneling guiding hole slot diminishes from top to bottom continuously, and the left and right sides narrows, symmetrically continuously until be connected with directed hole slot transitions smooth simultaneously.
Lock core and bearing and funneling guiding hole slot are on the same axis.
The upper end of described pipe is concordant with the upper end end face of funneling guiding hole slot, funneling guiding hole slot can in pipe flexible rotating.
The upper end end face of funneling guiding hole slot is circular, is convenient to key and easily inserts; Funneling guiding hole slot diminishes from top to bottom continuously, and the left and right sides narrows symmetrically continuously simultaneously, until be connected with directed hole slot transitions smooth, this structure can make key insert directed hole slot like a cork from funneling guiding hole slot; After key inserts directed hole slot, because the cross section shape and size of directed hole slot are all consistent with the shape and size in the aperture of the keyhole of lock body, key can insert keyhole like a cork.
The internal diameter of bearing and the lower end tight fit of directed hole slot, and weld together, funneling guiding hole slot can be rotated together with key when unblanking with directed hole slot.
the upper surface of lock body is provided with cannelure, and the internal diameter of cannelure is provided with the external screw thread connected with the internal thread of pipe, the top of described pipe and the external diameter tight fit of bearing, and welds together, and is convenient to be arranged on lock body by the utility model by pipe.The upper end of pipe is concordant with the upper end end face of funneling guiding hole slot, is guaranteeing that funneling guiding hole slot can, in pipe while flexible rotating, make the utility model profile more attractive in appearance.
Key is inserted funneling guiding hole slot and directed hole slot, along with the guiding of funneling guiding hole slot and the orientation of directed hole slot, key easily inserts keyhole.Rotate key, get final product easy for unlocking.The utility model has key guide function, solves people are difficult to the existing lock aiming at keyhole technological deficiency when night or insufficient light place and old man and key for blind men unblank.
Accompanying drawing explanation
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of front view being provided with the concrete structure of the lock of key guiding device according to the utility model proposes, and Fig. 2 is a kind of lateral view being provided with the lock of key guiding device according to the utility model proposes.
In figure, 1 is funneling guiding hole slot, and 2 is directed hole slot, and 3 is bearing, and 4 is lock core, and 5 is lock body, and 6 is keyhole, and 7 is cannelure, and 8 is pipe.
Detailed description of the invention
below in conjunction with embodiment, the utility model is described further.
Embodiment: as shown in Figure 1 and Figure 2, be provided with a lock for key guiding device, the upper surface of lock body 5 is provided with cannelure 7, and the internal diameter of cannelure 7 is provided with the external screw thread connected with the internal thread of pipe 8, the top of pipe 8 and the external diameter tight fit of bearing 3, and weld together.
The internal diameter of bearing 3 and the lower end tight fit of directed hole slot 2, and weld together, the cross section shape and size of directed hole slot 2 are all consistent with the shape and size in the aperture of the keyhole 6 of lock body 5.
It is circular funneling guiding hole slot 1 that the upper end end face of directed hole slot 2 is provided with upper end end face, and funneling guiding hole slot 1 diminishes from top to bottom continuously, and the left and right sides narrows, symmetrically continuously until be connected with directed hole slot 2 transitions smooth simultaneously.
Lock core 4 and bearing 3 and funneling guiding hole slot 1 are on the same axis.
The upper end of pipe 8 is concordant with the upper end end face of funneling guiding hole slot 1, funneling guiding hole slot 1 can in pipe 8 flexible rotating.
Working condition of the present utility model is: pipe is screwed in cannelure, installs the utility model.Key is inserted funneling guiding hole slot and directed hole slot, along with the guiding of funneling guiding hole slot and the orientation of directed hole slot, key easily inserts keyhole.Rotate key, get final product easy for unlocking.
