The soft key of the utility model adopts following technical scheme to realize.
Wherein soft key is by the shank of the key, key cover, soft key body is formed, key handle cover is on key cover, key cover passes the shank of the key, key cover connects with fixing pin with the shank of the key, its difference is that key is by the head grain, the standard grain, the tail grain is formed, head grain wherein, the standard grain, the tail grain connects with coupling spindle, described standard grain body is provided with groove and tongue and the groove axis hole and the tongue axis hole that can mesh, the groove axis hole aperture of groove upper end is less than the axis hole aperture of groove lower end, tongue axis hole aperture is maximum, standard grain side is provided with gathering sill, described head grain is provided with a groove, the tail grain is provided with a tongue, the head grain, the standard grain, the tail grain meshes by groove and tongue and links together with coupling spindle.
Another difference is no longer to be provided with original steel disc slide construction on the shank of the key, originally the structure slip is difficult, and soft key is deviate from key cover easily.The utility model is provided with the positioning bead chamber on the shank of the key, indoor spring and the positioning bead of being equipped with of positioning bead.
Particularly the front end at key cover is provided with the hole of bead, key cover location, and positioning bead is equipped with in the hole of bead in the location.
Lock core is synthetic by sheet under lock core last slice and the lock core, front end is the key trepanning, is provided with five metals sheet chamber, the left and right sides in the sheet under lock core last slice and the lock core, is provided with the lock core bend in the middle of the lock core, be provided with the hole of bead, key cover location in the insertion key end, the lock core end is provided with clutch chamber and jump ring groove.
For preventing that destructiveness from unblanking, add anti-drilling stiffened steel disc at the lock core front end.
The locking of key cover and lock core and releasing:
After key cover inserts lock core hole, promote the soft key of shank of the key forward moves forward thereupon, left and right two positioning beads in the key cover are under soft key squeezing action at this moment, part enters in the lock core key cover locating hole, before soft key did not withdraw from lock core, left and right sides positioning bead can't be got back in the key cover, and key cover is under the effect of left and right sides positioning bead, connect with lock core, key cover can't be withdrawed from.Promptly finish the work of key cover position and lock.As Figure 13, shown in Figure 14.
When removing the key cover lock-out state, pulling back the shank of the key withdraws from soft key from lock core and gets back in the key cover fully, this moment, soft key was not at extruding left and right sides positioning bead, withdraw from the shank of the key under the effect of pulling force, left and right sides positioning bead returns in the key cover, and key cover can withdraw from lock core, finish and remove the key cover lock-out state, as shown in figure 11.
The utility model has thoroughly solved the variety of issue that the former design of soft key occurs easily by changing the structure of soft key and lock core, has eliminated user's trouble and worry, the utility model can be simplified production technology, reduce production costs, improve practicality, the penetration and promotion of being more convenient for.
