Luggage coded lock

Abstract

A luggage coded lock is characterized in that a torsional spring used for keeping a lock hook at a locking position is arranged between the lock hook and a lock shell, a supporting part is arranged on one side, opposite to a locking notch, of the lock hook, and an elastic supporting piece is arranged between a movable rod and the lock hook. The elastic supporting piece comprises a fixed part fixed to the lock shell and an elastic locking arm extending from the fixed part to the supporting part, the elastic locking arm extends to form an avoiding arm opposite to the lock hook, and the avoiding arm extends to form a driving arm towards the movable rod. The movable rod is provided with a pulling part located on the side, close to the lock hook, of the driving arm, and the lock tongue can extrude the lock hook to rotate so that the supporting part can move back on to the elastic locking arm till the locking notch is meshed with the lock tongue. When the lock hook is located at the locking position, the elastic locking arm abuts against the supporting part so as to limit the spring bolt to be separated from the locking notch.

[0023] Please refer to Figures 1-6, a luggage combination lock according to the first embodiment of the present utility model, comprising a lock housing, a password wheel assembly 2, a button 3, a movable rod 4, and a lock hook 5. A lock core assembly 6 is provided on the button 3. The movable rod 4 is provided with a side vertical plate 41 with an inclined slot 410. The button 3 is provided with a guide post 31 that cooperates with the inclined slot 410. When the password wheel assembly 2 unlocks or the lock core assembly 6 unlocks, the button 3 can be pressed downward to drive the horizontal sliding of the movable rod 4 to drive the rotation of the lock hook 5 to unlock. The lock hook 5 can rotate from the unlocking position to the locking position where it only engages with the lock tongue 9. The lock hook 5 is provided with a locking notch 90 for engaging with the lock tongue 9. A torsion spring 5t is provided between the lock hook 5 and the lock housing to keep the lock hook 5 in the locking position. A support portion 51 is provided on the side of the lock hook 5 facing away from the locking notch 90. An elastic support member 7 is provided between the movable rod 4 and the lock hook 5. The elastic support member 7 includes a fixing portion 71 fixed on the lock housing and an elastic locking arm 72 extending from the fixing portion 71 towards the support portion 51. The elastic locking arm 72 extends away from the lock hook 5 with an avoidance arm 73, and the avoidance arm 73 extends towards the movable rod 4 with a driving arm 74. The movable rod 4 is provided with a pulling portion 42 on the side of the driving arm 74 close to the lock hook 5. The lock tongue 9 can squeeze the lock hook 5 to rotate so that the support portion moves away from the elastic locking arm 72 until the locking notch 90 engages with the lock tongue 9. When the lock hook 5 is in the locking position, the elastic locking arm 72 abuts against the support portion 51 to limit the lock tongue 9 from disengaging from the locking notch 90. The lock housing includes an upper cover 11 and a bottom plate 12.

[0024] The lock housing is provided with a card slot 111 for fixing the fixing portion 71 and a limiting portion 112 for restricting the moving range of the elastic locking arm 72.

[0025] The fixing portion 71 is a plate-like structure with a rectangular cross-section. The elastic locking arm 72 extends from the middle of the fixing portion 71 towards the support portion 51. The elastic locking arm 72 is a plate-like structure. A deformation portion 720 with a reduced cross-section is provided at the root of the elastic locking arm 72 close to the fixing portion 71.

[0026] The password wheel assembly 2 includes a wedge block 21 that can axially move when the password is correct.

When the first limiting strip 611 abuts against the wedge-shaped block 21, the second limiting strip 612 abuts against the limiting plate 32, and the lock core assembly 6 is in the locked state. When the second limiting strip 612 abuts against the wedge-shaped block 21, the first limiting strip 611 abuts against the limiting plate 32, and the lock core assembly 6 is in the unlocked state.

[0029] A ejecting block 8 is slidably connected to the lock case. A ejecting spring 8t is provided between the ejecting block 8 and the lock case. When the lock tongue 9 presses the ejecting block 8 until it abuts against the lock case, the ejecting block 8 is provided with a receiving cavity 80 that can accommodate the compressed ejecting spring 8t. The locking notch 90 engages with the lock tongue 9. The ejecting spring 8t is used to drive the ejecting block 8 to press the lock tongue 9 to disengage from the lock case when the lock hook 5 rotates to the unlocking position.

[0030] Similar to the prior art, the lock tongue 9 is provided with a mating notch 90 that cooperates with the locking notch 90. The password wheel assembly 2 includes a plurality of password wheels 23 sleeved outside the lock shaft 22. The wedge-shaped block 21 is fixedly connected to the lock shaft 22.

[0031] The elastic support member 7 is made of plastic.

[0032] In the present utility model, when the password is incorrect or the lock core assembly 6 is in the locked state, that is, when the lock hook 5 is in the locked position, the lock tongue 9 can press the lock hook 5 to rotate so that the support portion moves away from the elastic locking arm 72 until the locking notch 90 engages with the lock tongue 9 to achieve locking.

[0033] In the present utility model, the rack 21 can directly drive the password wheel 41 to rotate to zero, and the structure is simple.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
