appearance contract that is positioned lock body 30 is revolved in the hole 31, the other end of four compression springs 42 also can support to arrive on the end face of interlock turn 43 this moment again, then again a torque spring 67 is placed in secondary butted 66 the spring storage tank 662, and should butted 66 of pair place in the storage tank 36 of lock body 30, and utilize a latch to pass secondary butted pivot-juction hole 361 at lock body 30 rears and secondary butted 66 pivot-juction hole 663, and butted 66 of pair tied on lock body 30 together with torque spring 67 pivots, an end pin of this torque spring 67 can support to arrive on the cell wall of the storage tank 36 of lock body 30 simultaneously, other end pin then can support to arrive on the piece face of butted 66 of pair, then again an end of returning spring 64 is inserted and support to arrive in the spring of buckle piece 63 pushes away contract hole 632, and simultaneously buckle piece 63 is placed from top to bottom in the appearance contract slideway 38 of lock body 30, then utilize two-screw to pass the lockhole 621 of catch 62 and lock body 30 again, 381, and catch 62 locks are tied on the medial segment of the appearance contract slideway 38 that is covered on lock body 30, buckle piece 63 can be because of being subjected to the block of catch 62 at this moment, and can when slippage, break away from the spacing of lock body 30 by unexpected its, simultaneously, the other end of returning spring 64 also can support to arrive on the segmentum laterale cell wall that holds contract slideway 38, then again another torque spring 67 is placed in the spring storage tank 604 of turn fixture block 60, and the pivot contract groove 611 that will lead simultaneously butted 61 places outside butted pivot knot of the master seat 603 of Piao Xuandong fixture block 60, utilize a latch to pass main butted 61 top pivot-juction hole 612 and butted pivot-juction hole 605 of master of turn fixture block 60 again, tie on rotating block 60 together with another torque spring 67 pivots and will lead butted 61, an end pin of this torque spring 67 can support to arrive on the cell wall of the spring storage tank 604 of turn fixture block 60 simultaneously, other end pin then can support to arrive on main butted 61 pivot contract groove 611, again pivot knot seat 601 plants of turn fixture block 60 are gone in the saturating groove 32 of lock body 30, and utilize a latch to pass the turn fixture block pivot-juction hole 321 of lock body 30 and the pivot-juction hole 602 of turn fixture block 60, and turn fixture block 60 pivots are tied on lock body 30, and the master on the turn fixture block 60 also can place in the eluding groove 37 of lock body 30 butted 61 this moment, so the butted pivot-juction hole 371 of master that an also desirable latch of while passes lock body 30 and the pivot-juction hole 612 of main butted 61 below, and the lower ending pivot that will lead butted 61 is tied on lock body 30, then again pushing block 65 sliding sleeves are gone in the slippage slot 35 of lock body 30, and make its medial extremity subsides be butted on the horizontal block of buckle piece 63, outboard end then pastes on the pushing and pressing post 432 that is butted on interlock spin-block 43, then again turn fixture block 60 is down compressed, can make its hook piece 606 hooks on the button hook body 631 of buckle piece 63, also can finish simultaneously the combination of lockset, again this lockset is applied on the luggage case at last, can finishes combination.

When it is desired to unblank and makes boot release as shown in Figure 7, only need four key cylinders 53 of key 50 are at random inserted the four-keyhole 403 of core 40, and make this four key cylinder 53 down push against four fixture blocks 41, four fixture blocks, 41 down slippages of meeting this moment, all align mutually and make it revolve the portion of opening 413 with the block 312 of lock body 30, the springs 42 of the compression of four in it simultaneously also can compress because of the pushing and pressing that are subjected to compressing retaining groove 411, then utilize the turn portion 52 of the moving key 50 of hand-screw again, and make key 50 move core 40 turns, and when core 40 turns, it can drive the 43 and then turns of interlock spin-block by locator card post 406, its pushing and pressing post 432 can be taken advantage of a situation and be pushed against pushing block 65 slippage outward when 43 turns of interlock spin-block again, this moment, pushing block 65 meetings pushed against buckle pieces 63, and make its also slippage outward, with seasonal returning spring 64 compressions, and when treating the no hook of its hook piece that slides onto button hook body 631 and turn fixture block 60 606, turn fixture block 60 promptly can be by the elasticity pushing and pressing of main butted 61 and secondary butted 66 torque spring 67, and up outward winding, this moment, luggage case can be outwarded winding because of turn fixture block 60, and can open; In addition when it desires to make luggage case to close once again to finish, only need turn fixture block 60 is down compressed, and make extremely original position of key 50 turns, can promptly reach.

Borrow the structure of above-mentioned specific embodiment, can obtain following benefit: one because it is when desiring to unblank, only need key cylinder 53 to be inserted keyhole 403 and make its rotation one angle of taking advantage of a situation, can reach easily and promptly, so it can be because of not pushing briquetting, and make the action of unblanking can be simpler and easy, so it has convenience, simple and easy and rapid property when opening luggage case; Two because its key cylinder 53 is established rounded shape, and no teeth groove it on, so when its desire insertion keyhole 403, meeting be because of need not making teeth groove be meshed with the tooth piece, and can save considerable to the hole time, so its convenience, rapid property during than the 50 insertion turns of tool key.

In sum, the utility model has reached really in breakthrough structure, and has the utility model content of improvement, can reach usability and progressive on the industry again simultaneously, proposes novel patent application in accordance with the law.
