The utility model is characterized in that one end of a lock core near a lock ruler is provided with a hole, and a lock pin which has the equal length with the diameter of the lock core passes through the hole. Because the utility model uses a lengthened key or an iron sheet, the lock core and the lock ruler can not be separated, the lock can not be opened, and the lock which is opened by a universal key is prevented.
Description
The utility model relates to a kind of improved door lock core.
Existing door lock core directly touches sword iron, can separate sword iron with lock core with the lengthening key, and pass lock core with iron wire again and drive the internal lock rotation, thus a lock breakdown.
The purpose of this utility model just provides the lock core that a kind of lock core can not directly touch sword iron.
The utility model can be realized in the following manner: on existing lock core basis, an end of close sword iron is drilled with a hole, and length equates that with lock core diameter lock pin is fixed on the interpolation of hole.
The utility model is owing to the end at the close sword iron of lock core is drilled with a hole, fix with the lock pin that lock core diameter is isometric, thereby make foreign object can not directly touch sword iron, lock core is separated with sword iron with the lengthening key, can not be the lock breakdown, thus master key breakdown lock prevented.
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is a side view of the present utility model.
Fig. 2 is another side figure of the present utility model.
Please read accompanying drawing, on the basis of existing door lock core,, have the face in the lock hole of bead 2 to add brill one hole 3, see Fig. 2 near an end of sword iron.Length equates that with lock core diameter the lock pin 1 that hole interpolation human alloy material is made is fixing, sees Fig. 1.
