Specific embodiment

As shown in figures 1 to 6, a kind of specific embodiment of knob coded lock, including bottom case 1 and upper cover 2, the upper cover 2 fasten On the bottom case 1, the upper cover 2 is fixed on an opening edge of luggage, another opening edge of luggage is fixed with plate 3, The both ends of the plate 3 are equipped with plug 4, and two plugs 4 can be locked in the bottom case 1, are used for bottom case 1 and insert Plate 3 connects, so that two opening edges of luggage be made to connect together, realizes the closing of luggage.Coded lock is all to take this side Formula, this specific embodiment is specific to offer card slot 5 on the plug 4, and two end side surfaces of the bottom case 1 offer slotting Hole 6, the plug 4 are inserted into the jack 6, and the both ends of the bottom case 1 are slidably mounted with fixture block 7,7 energy of fixture block It is enough caught in the card slot 5, plug is prevented to be detached from jack, keep the connection of plate and bottom case, luggage is lockked.

As shown in figures 1-13, specifically, 1 intermediary form of bottom case has fixed frame 8, offers three in the fixed frame 8 A roller groove 9.It is provided with locking bar 10 on fixed frame 8, described 10 one end of locking bar forms lock tongue 11, along axial molding on locking bar 10 There are three card convex 12, three card convexs 12 are axially arranged in a line along locking bar 10.Lock there are three being arranged on the locking bar 10 13 are covered, card recessed 14 is formed in the inner circumferential of lock tube 13, the card convex 12 is adapted with the card recessed 14, a lock tube and corresponding one A card convex, when the card inside card convex is located at lock tube is recessed interior, locking bar can axially movable, when lock tube rotation keep card convex recessed with card Locking bar when corresponding to cannot be axially moved.The periphery of the lock tube 13 forms protrusion 15, and 13 periphery of lock tube is arranged with Idler wheel 16, the inner circumferential of the idler wheel 16 open up fluted 17, described raised 15 and are adapted with the groove 17, enable rotation roller Enough drive lock tube rotation.The roller groove 9, card convex 12, lock tube 13 are identical with the quantity of idler wheel 16.When assembly, the locking bar 10 It is erected on the fixed frame 8, the idler wheel 16 is located in the roller groove 9, pacifies between the lock tube 13 and the lock tongue 11 Equipped with latch bolt spring 18, when rotating three idler wheels, allow three lock tubes turn to card it is recessed with card convex to it is corresponding when promotion lock tongue make Locking bar moves axially, and can also reset under the action of latch bolt spring, i.e., lock tongue can be compressed；As long as there is an idler wheel Less than position, lock tongue cannot be compressed for rotation.

Fixing axle 19 is formed close to 11 position of lock tongue on the bottom case 1, is arranged with knob in the fixing axle 19 20, there are two pulling plate 21, two pulling plates 21 are separately connected the fixture block 7 of two sides, rotation rotation for the periphery connection of the knob 20 Button pulls fixture block by pulling plate, and specifically, pulling plate two have drag hook, and wherein the drag hook of one end is hooked on fixture block, the drawing of the other end Hook is hooked on the outer wall of knob, and two pulling plates of corresponding two fixture blocks are pulled in the two sides of knob respectively, rotates knob, so that it may Xiang Zhong Between pull two fixture blocks, keep the fixture block positioned at bottom case two sides mobile to centre, plug unclamped, separates plate with bottom case, in fact Now open luggage.Fixture block spring 22 by from fixture block 7 to the springing of bottom case two sides is installed between two fixture blocks 7 and bottom case 1, when After rotating knob opening luggage, fixture block is resetted under the action of fixture block spring, returns to original position.In order to realize knob Locking, the periphery of the knob 20 also form locked groove 23 compatible with the lock tongue 11, and rotation knob rotates locked groove, moves Latch bolt position is opened, i.e., upon rotation of the knob, inherently compresses lock tongue.So when three idler wheel rotation position clock synchronization (Password Inputs Correctly), knob could rotate, and open luggage, as long as when there is a rotation position not to (password bad) in three idler wheels, Knob cannot rotate, and can not open luggage.

Knob hole 24 and idler wheel hole 25 are offered in the upper cover 2, the knob 20 leads to upper cover 2 from the knob hole 24 Top, the idler wheel 16 lead to above upper cover 2 from the idler wheel hole 25, can operation knob and idler wheel above upper cover.

In order to enable password to change, raised 15 length is less than the length of the lock tube 13, the groove 17 Length is less than the length of the idler wheel 16.The locking bar 10 is arranged with far from described 11 one end of lock tongue and pulls set 26, described to pull Throw rod 27 is fixed on the periphery of set 26.Password is correct, and after opening luggage, throw rod is pulled inside luggage, pushes lock tube It is mobile, it is separated from each other protrusion with groove, realizes that lock tube can relatively rotate with idler wheel, at this moment, rotation roller makes this Under state (the correct state of the state that locking bar can move axially in lock tube, i.e. password), corresponding idler wheel number changes, pine Throw rod is opened, lock tube is shot back under the action of latch bolt spring, and protrusion is made to continue clamping with groove, opens luggage needs again next time Idler wheel is rolled to the position corrected one's mistakes.1 bottom of bottom case, which offers, pulls hole 28, and the throw rod 27 pulls hole 28 from described Place is pierced by, and the hole 28 of pulling is L-type, makes to pull Kong Youyi chuck, when changing password, throw rod is moved on to the card for pulling hole Lock tube can be pushed on platform, separate lock tube with idler wheel, it is more laborsaving, it, will after the completion of changing password without one straight pull of hand Throw rod is moved back to original position, and lock tube is shot back under the action of latch bolt spring, make protrusion with groove continue clamping, idler wheel with Lock tube continues to lock.

Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are practical new to this The various changes and improvements that the technical solution of type is made should all fall into the protection scope that the utility model claims book determines It is interior.
