The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
As shown in Figure 1, a kind of key 1, its key embryo is made up of spoon bar 1-1 and the shank of the key 1-2, and the cross section of said spoon bar 1-1 is the grooved that behind spoon bar 1-1 central axis Rotate 180, overlaps fully; Be respectively arranged with the tooth sign indicating number 1-4 of different depth on two spoons of faces of each symmetry of said spoon bar 1-1.Said the shank of the key 1-2 is marked with the sign 1-3 of indication spoon face opening sequence.
The cross section of said spoon bar 1-1 is " ten " font, " one " font, " rice " font, " curve " type, " X " type.
Embodiment 1: as shown in Figure 2, and the grooved that the cross section of said " one " font spoon bar 1-1 overlaps behind the spoon bar 1-1 central axis Rotate 180 fully.
To a kind of latch mechanism shown in Figure 7, comprise key as shown in Figure 11, sleeve pipe 2, lock core cover 3, lock core 4, round end pellet shot from a slingshot 9, billiards plate 10, tack pellet shot from a slingshot 11 like Fig. 3, between said lock core 4 and the said lock core cover 3 sleeve pipe 2 is housed; Have the pellet shot from a slingshot hole that communicates with lock core marble hole and lock core sleeving marble hole on the said sleeve pipe 2; At the top of sleeve pipe 2 dial axis 6 is arranged; Shifting block 5 and fixed, back-moving spring 7 are housed in the upper sleeve portion 2 of lock core 4, and said shifting block 5 flexibly connects with lock core 4, and bearing pin 8 is fixed on the shifting block 5; The transverse opening 3-2 that the top of lock core cover 3 is provided with longitudinal opening 3-1 and communicates with this longitudinal opening; On sleeve pipe 2, overlap the corresponding position of 3 openings with lock core, the transverse opening 2-2 that is respectively equipped with longitudinal opening 2-1 and communicates with this longitudinal opening; Offer the suitable groove of spoon bar cross section grooved on the said lock core with said key.
There is a boss lower end of said shifting block 5, and lock core 4 upper ends have the groove that matches with boss, thereby forms the connection of living each other.
Be used in a user mode structure chart on the padlock like Fig. 8 key of the present invention and latch mechanism.When unblanking, press earlier NO.1 face direction and insert key 1 rotational lock core once, extract key 1 behind the lock core that resets; Insert key 1 by the opposite flank of tooth (NO.2) direction again; When key 1 drives lock core and sleeve pipe 2 rotations,, stir dead bolt 12 and will lock unlatching through the dial axis on the sleeve pipe; Dead bolt 12 is under latch bolt spring 13 effects, and through the dial axis on the sleeve pipe 26, drive key 1, lock core 4, sleeve pipe 2 are got back to original position; Shifting block 5 is with in the sleeve pipe 2 rotating ways; Dial axis 6 on it is blocked by the longitudinal opening wall of lock core cover 3, under the effect of back-moving spring, resets to Fig. 3 position.At this moment, latch mechanism locking again.
Embodiment 2: shown in Fig. 9 to 13, different with embodiment 1 is: the spoon bar 1-1 of key 1 of the present invention is " ten " font.The grooved that overlaps fully behind the spoon bar 1-1 central axis Rotate 180 like Figure 10 said " ten " font spoon bar 1-1 cross section.
Embodiment 3: shown in Figure 14 to 18, different with embodiment 1 is: the spoon bar 1-1 of key 1 of the present invention is " rice " font.The grooved that overlaps fully behind the spoon bar 1-1 central axis Rotate 180 like Figure 15 said " rice " font spoon bar 1-1 cross section.
Operating principle of the present invention: extremely shown in Figure 5 when pressing NO.1 face direction insertion key 1 like Fig. 3; Round end pellet shot from a slingshot 9 is concordant with the external surface of lock core 4; At this moment during key 1, lock core 4 rotates thereupon, makes shifting block 5 equidirectional thereupon rotation in last moving; At this moment the bearing pin 8 on the shifting block 5 has left the longitudinal opening 3-1 and the longitudinal opening 2-1 of sleeve pipe 2 of lock core cover 3, moves to the end (position as shown in Figure 4) that lock core overlaps the transverse opening 2-2 of 3 transverse opening 3-2 and sleeve pipe 2.At this moment sleeve pipe 2 separates with lock core cover 3, and sleeve pipe 2 and lock core cover 3 can be relatively rotated; Past then rightabout key 1 resets lock core 4 and extracts key, and at this moment, shifting block 5 still rests on Fig. 4 position together with bearing pin 8.After pressing NO.2 face direction insertion key 1 again, the structure of this lock core is as shown in Figure 5, at this moment; All tack pellets shot from a slingshot 11 are concordant with sleeve pipe 2 external surfaces, and at this moment key 1, and key 1 drives lock core 4 and rotates together with sleeve pipe 2; Make the dial axis 6 on the sleeve pipe 2 stir dead bolt, reach the purpose of opening lockset.Backward rotation key 1; Make lock core 4 and sleeve pipe 2 overlap 3 backward rotation with respect to lock core simultaneously; Shifting block 5 backward rotation thereupon under the acting in conjunction of lock core 4 and transverse opening, when the bearing pin on it 8 forwarded lock core to and overlaps 3 longitudinal opening positions, shifting block 5 reset to position shown in Figure 3.When unblanking again, need the above process of repetition.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
