Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

In the case of the present utility model, as shown in fig. 1 to 3, the case includes a linkage case lock, a case 11, and a front cover 12 covering a side of the case 11. The linkage case and bag lock is fixed on the top surface inner wall of box 11, and the linkage case and bag lock includes lock shell 2 and outside spring bolt subassembly 3, and the inside interior latch hook 7 that is equipped with of lock shell 2, outside spring bolt subassembly 3 fixed mounting are in the side inner wall middle part position of box 11, and protecgulum 12 is equipped with the first hasp 13 with interior latch hook 7 closure and is equipped with the second hasp 14 with outside spring bolt subassembly 3 lock.

Referring to fig. 2 and 3, the lock housing 2 is provided with a movable member 6, a button assembly 4, a combination wheel assembly 5, an inner shackle 7, an outer locking bolt assembly 3, and a conversion block 8.

The case lock is unlocked by pressing, and in combination with fig. 4 and 5, the button assembly 4 includes a button body 41 movable in a height direction with respect to the lock case 2, and the movable member 6 is a button assembly 4 slidable in a length direction of the lock case 2. The movable member 6 is disposed at a side of the button body 41, the button body 41 extends out of the guide post 45 toward the movable member 6, the movable member 6 is provided with a guide groove 61 into which the guide post 45 is inserted, the guide groove 61 is disposed obliquely with respect to a horizontal plane, and in an assembled state, the guide post 45 is inserted into the guide groove 61. Through applying a downward pressure to button body 41, button body 41 atress downward movement, guide post 45 can support the guide slot 61 cell wall of moving part 6 to order about moving part 6 to slide towards the unblock direction, will press button body 41 in the ascending motion of vertical direction to the moving part 6 in the ascending motion of transverse direction, thereby can simplify the structure of tool to lock, reduce the whole volume of case and bag lock.

In order to be able to achieve locking, i.e. to limit the movement of the push button in the height direction. The button assembly 4 further comprises a lock cylinder 42 and a clutch block 43, wherein the lock cylinder 42 is fixedly connected with the clutch block 43, the lock cylinder 42 and the clutch block 43 are rotatably installed in the button body 41, and when the lock cylinder 42 rotates, the clutch block 43 rotates together with the lock cylinder 42. The cipher wheel assembly 5 is installed in the side of the button assembly 4, and the cipher wheel assembly 5 comprises a telescopic wheel shaft 51, and when the cipher is correct, the wheel shaft 51 can move in a telescopic way, and when the cipher is wrong, the wheel shaft 51 is locked and cannot move in a telescopic way, as the traditional cipher wheel assembly 5 is the same.
