The specific embodiment:

See shown in the accompanying drawing 1～4, the utility model includes the loam cake 10 and the lower cover 20 of mutual fastening, in loam cake 10 and the formed cavity of lower cover 20 fastenings, lock core 30, shell fragment 40 and several push buttons 50 are housed also, this push button 50 is by last push button 51, down push button 52 and the contiguous block 53 that is connected between them are formed, the described push button 51 of going up is identical with following push button 52 shapes and the big or small equidirectional in angle of inclination is opposite, and offers a breach 54 on the contiguous block 53; Be arranged with on loam cake 10 and the lower cover 20 with several push buttons 50 on push button 51, the following corresponding key hole 11 of push button 52 size shape and 21; Lock core 30 is a shaped as frame structure, its framework inner side edge is fixed with some blocks that evenly are spaced 31, breach 54 on the size shape of this block 31 and the contiguous block 53 is corresponding, shell fragment 40 is housed in lock core 30, this shell fragment 40 is mainly stretched several outstanding blend stops that evenly is spaced 42 by rectangular strip 41 and on rectangular strip 41 and is constituted, after the assembling, above-mentioned blend stop 42 is spaced between the adjacent blockers on the lock core 30 31, and each push button 50 is embedded between key hole 11 and 21, and contiguous block 53 is then between the adjacent blockers on the lock core 30 31; On the lateral surface little pushing block 32 is arranged on one side in lock core 30 frameworks, after the assembling, stretch outstanding in the hole 12 of this little pushing block 32 by loam cake 10 and lower cover 20 edges; Collude groove 33 and on lock core 30 framework another side lateral surfaces, have one, on loam cake 10 inside edges, be equiped with a lock hook 60, lock hook 60 is by the clamp 61 that can sandwich notebook one front cover and collude body 62 and form, after the assembling, collude body 62 and wore the colluding hole 13 of loam cake 10 edges and colluded and be located at the colluding on the groove 33 of lock core 30.Form the projection 421 of cross section on one side of each blend stop 42 of described shell fragment 40, match for the projection 531 of " △ " shape and with the projection 421 of blend stop 42 and on contiguous block 53 two sides of push button 50, also form the cross section for " △ " shape.The last push button 51 of described push button 50, following push button 52 are for being shaped as the push button of butterfly shape.Described push button 50 numbers can be six.Described blend stop 42 is "T"-shaped blend stop.

In assembling during coded lock, the contiguous block 53 in the connection between push button 51 and the following push button 52 is fastened between the adjacent blockers 31 on the lock core 30, and lock hook 60 colludes and is located at the colluding on the groove 33 of lock core 30; As illustrated in fig. 1 and 2, when push button 50 is installed, some push buttons 50 will can be installed near the last push button 51 of breach 54 in the key hole 11 of loam cake 10 by configuring sequence of coden, the following push button 52 of remaining push button 50 away from breach 54 will be installed in the key hole 11 of loam cake 10.At this moment, be horizontal away from the block 31 on breach on push button 50 its contiguous blocks 53 of breach 54 54 and the lock core 30, but owing to misplace up and down near the block 31 on breach on push button 50 its contiguous blocks 53 of breach 54 54 and the lock core 30, therefore, lock core 50 is stuck and can not slides; During use, when people can not press correct password push button 50, the breach and the block 31 on the lock core 30 that always have on the contiguous block 53 on the push button 50 were in the state of dislocation up and down, thereby lock core 50 can not be slided; And the push button 50 of pressing proper password as the user is when being those near the last push button 51 of breach 54, breach 54 on the contiguous block 53 of these push buttons 50 is just parallel with the block 31 on the lock core 30, breach 54 on all like this push button 50 contiguous blocks 53 is parallel with the block 31 on the lock core 30, just can make lock core 30 translations by promoting little pushing block 32, thereby the colluding between the groove 33 of colluding of opening on lock hook 60 and the lock core 30 closed connection, lock hook 60 is unloaded, finally open notebook.In this process, because shell fragment 40 utilizes the interval barrier effect of its each "T"-shaped blend stop 42, prevent lock core about 30 dislocation, and be positioned at the projection 421 of " △ " shape on the side of shell fragment 40, be the changing of the relative positions up and down that cooperatively interacts of the projection 531 of " △ " shape with cross section on contiguous block 53 two sides of push button 50, but the two states that makes push button 50 be in conducting all the time and block, because push button 50 has adopted the big or small equidirectional opposite configuration in last push button 51 and angle of inclination identical with following push button 52 shapes, therefore, can realize push button 50 by the positive and negative installation of above-mentioned requirements, and can prevent that push button 50 is pushed out and come off.Certainly, the contour structures of push button 50 can carry out freely changing as required.

From the above, the utility model is a kind of push-button puzzle lock with integral body safe and reliable, easy to use, that form to coordinate with notebook again.
