Abstract
The invention relates to an expanded key and a lock core used with the same. The key comprises a key handle, a key protective case, a center straight key which is fixed on the key handle and bending keys which are arranged at two sides of the center straight key. The lock core comprises a cylindrical iron shot, a cylindrical iron shot head, a quadrangular iron shot, a quadrangular iron shot head,a lock core, a front lock part and a rear lock part. As the expanded key takes a structure which is formed by the straight key at the middle and the bending keys at two sides, one key is divided intothree heads, and the straight key at the middle is used for protecting the bending keys at the two sides so that the bending keys can not be damaged due to excessive force borne by the bending keys. The lock core used with the expanded key is hard to be opened by a common unlocking tool and has high safety factor of the lock, and springs at two sides of the lock core solve the problem that the key is manually withdrawn to the protective case after the key is pulled out each time, thus the lock core is more humanity when in use. The expanded key and the lock core have simple structure and can be applied to various locks of various fields.

The specific embodiment
Embodiment:
Structural representation of the present invention is like Fig. 1,2,3, shown in 4; Expansion key of the present invention; Include key handgrip 1, key protective case 2 and be fixed on central straight formula key 4 on the key handgrip 1, be arranged on the musical form key of central straight formula key 4 both sides; Wherein the musical form key includes some first musical form keys joint 6, some second musical form key joints 7 of fluted 71 of making; Wherein some first musical form key joints 6 pass the adapter sleeve 61 that is made at upper and lower side and middle part each other through musical form key axle 5 and link together; Some second musical form key joints 7 pass the adapter sleeve 61 that is made at upper and lower side and middle part each other through musical form key axle 5 and link together; Also pass the adapter sleeve 61 that is made at upper and lower side and middle part each other through musical form key axle 5 between first musical form key joint, 6 and the second musical form key saves 7 and link together, spring 3 is installed in the set groove of spoon protective case 2, and key protective case 2 is contained on the key handgrip 1.
In the present embodiment, the end of above-mentioned second musical form key joint 7 also is provided with musical form key bit 8.
The present invention and the matching used lock core of expansion key; Include anterior 14, the lock rear portion 15 of cylindrical abrasive grit 9, cylindrical abrasive grit head 10, four prism type abrasive grit 11, four prism type abrasive grit head 12, core 13, lock, wherein cylindrical abrasive grit head 10 is installed in the core 13, and cylindrical abrasive grit 9 is installed in the lock anterior 14; And cylindrical abrasive grit 9 is corresponding with the position of cylindrical abrasive grit head 10; Cylindrical abrasive grit 9 places the outside of cylindrical abrasive grit head 10, and the outside of cylindrical abrasive grit 9 also is equiped with back-moving spring 3, and four prism type abrasive grit head 12 is installed in the core 13; Four prism type abrasive grit 11 is installed in the lock anterior 14; And four prism type abrasive grit 11 is corresponding with the position of four prism type abrasive grit head 12, and four prism type abrasive grit 11 places the outside of four prism type abrasive grit head 12, and the outside of four prism type abrasive grit 11 also is equiped with back-moving spring 3; Lock rear portion 15 is installed in the rear end of lock anterior 14, and links together.The groove 71 that second musical form key joint 7 is made can fall into into cylindrical abrasive grit head 10, reaches the effect of Fig. 9.
Four prism type abrasive grit 11, four prism type abrasive grit head 12 and cylindrical abrasive grit 9,10 holding positions of cylindrical abrasive grit head can not be shifted one's position.As shown in Figure 5, cylindrical abrasive grit head 10 and cylindrical abrasive grit 9 are vertical with core 13, so can use cylindrical.But every group of four prism type abrasive grit 11 is parallel to each other with four prism type abrasive grit head 12, and be as shown in Figure 6, is different with the angulation of core 13, therefore will make four prism type, in order to avoid after the abrasive grit rotation, block core 13 it can not be rotated.
Operating principle of the present invention is following: after key injects lock, will occur like Fig. 8, situation shown in Figure 9.After extracting key, key protective case 2 can be to recovery under the effect of spring 3, because the power that key protective case 2 reclaims makes the straight mutually formula key of two musical form keys of straight formula key 4 both sides draw close and be withdrawn in the key protective case 2.Return to the situation of Fig. 1.Under this state, because the effect of spring 3, two musical form keys of straight formula key 4 and both sides can contract in protective case 2 always.Make it can not mark, thereby avoided the accidental damage that in the process of carrying, key caused because of unexpected factors such as vibrations.
