The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1 to Figure 3, the utility model mechanical lock comprises shell 1 and lock ring 2, shell is divided into loam cake 11 and lower cover 12, shell is provided with keyhole 13 and two holes 14 that supply the lock ring two ends to penetrate, 15, wherein lock ring has a positive stop end 21 and a folding end 22, positive stop end 21 is spacing in shell 1, folding end 22 can be extracted shell 1 out, positive stop end 21 comprises bar portion 211 and end 212, bar portion 211 is provided with a projection 2111 and one recessed groove 2112, recessed groove 2112 is between projection 2111 and end 212, and end 212 is provided with a joint pin 2121, and joint pin 2121 has a ring spring 3 away from a termination of end 212; The inwall of shell is provided with a stopper slot 16 and stopper slot 17, and stopper slot 16 is arranged in a right angle with stopper slot 17, and lower cover 12 inwalls also are distributed with two combination pin holes 18 to old, and the corresponding lower cover pin hole of loam cake 11 inwalls 18 places are provided with combination pin 19.Ring spring 3 is arranged in stopper slot 16, one flexure strip 4 is set in the stopper slot 17, flexure strip 4 is folded to form a bending end 41 and openend 42, bending end 41 has a radian, its radius of curvature is greater than the openend bore, recessed groove 2112 when sealed on the flexure strip openend 42 clamping lock ring positive stop ends, the bar portion 211 when lock is in unlatching between flexure strip openend 42 clamping recessed grooves and the end.

The private key 5 of above-mentioned mechanical lock comprises a squeezing handle 51 and a key bar 52, key bar 52 have one flat 521, wherein flat two ends form the boss perpendicular to key bar 52.

The assembling process of this mechanical lock is, each parts are assembled as mentioned above, then loam cake, lower cover combined by combination pin.When sealed lock ring is pressed in shell, flexure strip is slided in the recessed groove of lock ring, promptly reach sealed purpose, when opening, the key bar of private key is passed through the keyhole insertion of shell, make the centre of the flat head insertion doubling flexure strip of key, the twisting key, the projection that flat capitiform is become struts the doubling end of doubling flexure strip, make the locking bar diameter of the opening of flexure strip greater than lock ring, lock ring moves by the elastic force of the ring spring under the positive stop end, makes the folding end of lock ring shift out shell, reaches the purpose of opening lockset.

The lockset shell and the key of this practical property all adopt plastics to make, and it is heart-shaped that the shell of lock is.It is heart-shaped that the squeezing handle of key is.
