[0035] In combination Figures 2 to 5 , the luggage coded lock of the embodiment further comprises a locking mechanism and a swing button assembly 3 installed in the lock shell 2, and the luggage coded lock is suitable for luggage with a multi-layer structure, and will be described by taking the luggage coded lock suitable for the luggage with the multi-layer structure as an example. The locking mechanism of the luggage coded lock comprises two groups of hooks, one group of hooks can be used to lock the zipper piece of the zipper strip, and the other group of hooks can be used to lock the front cover plate of the compartment layer of the luggage body. In addition, in order to realize multiple unlocking modes, the locking mechanism further comprises a coded wheel assembly 4 and a lock core assembly 5 located in the lock shell 2, that is, the luggage coded lock can be unlocked by a code or a key. The locking mechanism further comprises a movable piece 8 used to abut against the hooks to realize unlocking, a first unlocking mechanism 6 and a second unlocking mechanism 9, and the swing button assembly 3 is used to drive the movable piece 8 to slide to the left (a first unlocking direction) or to the right (a second unlocking direction). When the movable piece 8 slides to the right, the movable piece 8 unlocks the first group of hooks through the first unlocking mechanism 6. When the movable piece 8 slides to the left, the movable piece 8 unlocks the second group of hooks through the second unlocking mechanism 9.

[0036] In the embodiment, in combination Figures 2 to 4 , two lock holes are formed at the top end surface of the face shell 21, and a first hook 71 rotatably installed in the face shell 21 is arranged in each lock hole. An elastic piece is arranged between the first hook 71 and the face shell 21 to drive the first hook 71 to flip upwards to the locked state. In order to realize the anti-theft function, the movable piece 8 abuts against the first hook 71 through the first unlocking mechanism 6 to realize locking. In order to facilitate assembly and protect the first unlocking mechanism 6, in combination Figure 3The lock shell 2 is further provided with a cover plate 25 covering the first unlocking mechanism 6, and the cover plate 25 is fixed by being pressed against the surface shell 21. The first unlocking mechanism 6 comprises two first locking blocks 61, each of which is matched with a first locking hook 71. The two first locking blocks 61 are installed in the cover plate 25, and each of the first locking blocks 61 can slide in the cover plate 25 in a direction perpendicular to the length direction of the surface shell 21. The top end of the cover plate 25 extends outwards in the form of a pair of mounting ears. The two side faces of the first locking hook 71 extend outwards in the form of cylindrical hinge portions. During assembly, the hinge portions are supported on the top ends of the mounting ears, so that the cover plate 25 supports the first locking hook 71, and the first locking hook 71 can rotate relative to the lock shell 2.

[0037] See Figure 4 The first locking hook 71 comprises a hook portion 711 and a clamping portion 712, and the hook portion 711 is used for hooking the zipper piece. The first locking block 61 comprises a straight strip-shaped strip portion, and the strip portion is provided with an unlocking slot 62. In the locked state, the outer side face of the strip portion of the first locking block 61 abuts against the clamping portion 712 of the first locking hook 71. At this time, the clamping portion 712 is misaligned with the unlocking slot 62, so as to limit the rotation of the first locking hook 71. During unlocking, the first locking block 61 slides in the width direction of the cover plate 25. After the unlocking slot 62 is aligned with the clamping portion 712, the clamping portion 712 can be placed into the unlocking slot 62, so that the first locking hook 71 is no longer limited in rotation and can be unlocked. The elastic member can drive the first locking hook 71 to automatically return. Similarly, in order to enable the first locking block 61 to automatically return, an elastic member is arranged between the first locking block 61 and the cover plate 25.

[0038] In combination with Figure 4 In order to realize the unlocking movement of the first locking block 61 by pushing, the movable member 8 in the lock shell 2 is linked with the first locking block 61. Specifically, the bottom face of the first locking block 61 extends outwards in the form of a protrusion 63, the end portion of the movable member 8 close to the first locking block 61 is provided with a groove for inserting the protrusion 63, the groove is provided with a second inclined surface 84, and the protrusion 63 is provided with a first inclined surface 64 complementary to the second inclined surface 84. As a preferred scheme, the cross-sectional shape of the protrusion 63 of the first locking block 61 is trapezoidal. During work, when the movable member 8 moves in the unlocking direction, the second inclined surface 84 of the groove of the movable member 8 abuts against the first inclined surface 64 of the protrusion 63 of the first locking block 61, so as to convert the transverse movement of the movable member 8 into the longitudinal movement of the first locking block 61, thereby realizing the unlocking of the first locking block 61 from the rotation limitation of the first locking hook 71.

[0039] In order to unlock the first locking hook 71 of the password lock, the movable member 8 must be pushed to unlock. The knob assembly 3 is a force applying member, and therefore the knob assembly 3 needs to push the movable member 8 to slide after being subjected to external force. Therefore, the movable member 8 is arranged below the knob assembly 3 and extends outwards in the form of a wedge-shaped portion 81 towards the knob assembly 3. In combination withFigure 6 The tumbler assembly 3 comprises a rotating shaft 33 fixed in the lock shell 2, a tumbler body 31 swingable about the rotating shaft 33, and a clutch block 32 inserted in the tumbler body 31. The wedge portion 81 is provided with at least one wedge surface, and the bottom surface of the tumbler body 31 extends towards the wedge surface with an unlocking portion abutting against the wedge surface. Since the combination lock of the present embodiment is applicable to multi-layer luggage, i.e. the movable member 8 slides in different directions to control different groups of the lock hooks to be unlocked, the wedge portion 81 is provided with two symmetric wedge surfaces, the first wedge surface 82 is inclined upward, and the second wedge surface 83 is inclined downward, the first wedge surface 82 and the second wedge surface 83 are oppositely inclined, and the tumbler body 31 is provided with at least two unlocking portions, the first unlocking portion 311 corresponds to the first wedge surface 82, and the second unlocking portion 312 corresponds to the second wedge surface 83. In other embodiments, if the lock shell 2 is provided with only one group or one lock hook, the wedge surface of the wedge portion 81 only needs to be provided with one, and the unlocking portion of the tumbler body 31 also only needs to be provided with one. Figure 5 Figure 7 The wedge portion 81 is provided with two symmetric wedge surfaces, the first wedge surface 82 is inclined upward, and the second wedge surface 83 is inclined downward, the first wedge surface 82 and the second wedge surface 83 are oppositely inclined, and the tumbler body 31 is provided with at least two unlocking portions, the first unlocking portion 311 corresponds to the first wedge surface 82, and the second unlocking portion 312 corresponds to the second wedge surface 83. In other embodiments, if the lock shell 2 is provided with only one group or one lock hook, the wedge surface of the wedge portion 81 only needs to be provided with one, and the unlocking portion of the tumbler body 31 also only needs to be provided with one.

[0040] In the unlocked state of the combination lock, an external force presses the tumbler body 31, the tumbler body 31 swings about the rotating shaft 33 to the left lower side or the right lower side, the unlocking portion of the tumbler body 31 abuts against the wedge surface of the wedge portion 81 of the movable member 8 to drive the movable member 8 to slide to the right side or the left side, so as to cooperate with the first unlocking mechanism 6 and the second unlocking mechanism 9 to unlock different groups of the lock hooks.

[0041] In combination with Figure 7 Figure 8 ​​In order to limit the swing of the swing knob body 31 and achieve the locking, in the embodiment, the left side of the swing knob assembly 3 is provided with a password wheel assembly 4. The password wheel assembly 4 comprises a wheel shaft 41 arranged along the length direction of the lock shell 2 and capable of reciprocating and retracting, and a reset spring 42 sleeved on the outer circumferential side of the wheel shaft 41. It should be noted that the password wheel assembly 4 is a conventional password wheel structure, and the reset spring 42 is an elastic reset member of the password wheel assembly 4. When the password is correct, the wheel shaft 41 can reciprocate and retract, and when the password is incorrect, the wheel shaft 41 cannot retract. The end of the clutch block 32 towards the wheel shaft 41 is provided with a clamping groove 321 for inserting the wheel shaft 41, and in the locked state, the end of the wheel shaft 41 is inserted into the clamping groove 321. In order to improve the anti-theft performance and enhance the clamping force between the wheel shaft 41 and the swing knob assembly 3, as a preferred solution, the cross-sectional shape of the clamping groove 321 is V-shaped, and the end of the wheel shaft 41 towards the clamping groove 321 is V-shaped. The working process of the password wheel assembly 4 is as follows: when the password is incorrect, the wheel shaft 41 is in the extended state and cannot retract, the end of the wheel shaft 41 abuts against and clamps the clutch block 32, the clutch block 32 cannot swing around the rotating shaft 33, and the locking is achieved. When the password is correct, the wheel shaft 41 is in the retractable state, and the left side of the swing knob body 31 is pressed downward, so that the swing knob body 31 swings to the right and downward. The swing of the swing knob body 31 will swing the clutch block 32, and the clutch block 32 will retract the wheel shaft 41 during the swing. In addition, the unlocking part of the swing knob body 31 will abut against and push the wedge-shaped part 81 of the movable part 8 to slide, thereby indirectly unlocking the lock hook. When the swing knob body 31 is removed from the external force, the reset spring 42 of the password wheel assembly 4 in the compressed state will drive the clutch block 32 and the swing knob body 31 to rotate to the locked state by the elastic force thereof.

[0042] In combination Figure 7 and Figure 9, in order to be able to adopt a variety of ways to unlock, the right side of the knob assembly 3 is provided with a lock cylinder assembly 5. The lock cylinder assembly 5 is located on the right side of the knob assembly 3, and the password wheel assembly 4 is located on the left side of the knob assembly 3. The lock cylinder assembly 5 includes a lock cylinder body 51 rotatably mounted in the lock shell 2, the lock cylinder body 51 extends towards the knob assembly 3 and abuts against the stop block 52, and the clutch block 32 extends towards the stop block 52 and abuts against the stop block 52. In the locked state of the password wheel assembly 4, the left side of the clutch block 32 is clamped with the shaft 41 of the password wheel assembly 4, even if the stop block 52 of the lock cylinder body 51 is misaligned with the protrusion 322 of the clutch block 32, the clutch block 32 cannot be swung. In order to solve this technical problem, the knob body 31 is provided with a sliding groove 313 along the length direction of the lock shell 2, the clutch block 32 is inserted into the sliding groove 313, and the clutch block 32 can slide along the sliding groove 313 towards the length direction of the lock shell 2. The middle part of the clutch block 32 is provided with a long hole 323 along the length direction of the lock shell 2, and the shaft 33 is inserted into the long hole 323, and the shaft 33 can slide in the long hole 323. In addition, in order to improve the structural strength of the lock, the end face of the stop block 52 towards the clutch block 32 is a left-down curved arc surface.

[0043] In combination Figure 7 and Figure 9 , the working process of the lock cylinder assembly 5 of the embodiment is as follows: in the locked state, the distance between the stop block 52 and the end of the shaft 41 is equal to the distance between the clamping groove 321 of the clutch block 32 and the outer side of the protrusion 322. When locked, the protrusion 322 of the clutch block 32 abuts against the stop block 52, so that the clutch block 32 cannot be swung. When unlocked, the lock cylinder body 51 is rotated, the lock cylinder body 51 is rotated and drives the stop block 52 to rotate, the stop block 52 is separated from the protrusion 322 of the clutch block 32 after rotating, so as to release the rotation restriction of the clutch block 32, then a downward pressure is applied to the knob body 31, the knob body 31 is swung around the shaft 33, since the shaft 41 clamps the left side of the clutch block 32, but the right side of the clutch block 32 is not abutted by the stop block 52 of the lock cylinder body 51, during the swinging of the knob body 31, the shaft 33 slides relative to the long hole 323 of the clutch block 32, that is, the clutch block 32 slides in the sliding groove 313 of the knob body 31 in the direction away from the shaft 41, after the clutch block 32 slides to the end of the shaft 41 and is separated from the clamping groove 321, the clutch block 32 swings with the knob body 31, the unlocking part of the knob body 31 abuts against the wedge block of the movable part 8, thereby indirectly cooperating with the locking mechanism to unlock the lock hook.

[0044] In another embodiment, if the lock does not need to be provided with the function of key unlocking, the lock cylinder assembly 5 is not needed, the clutch block 32 and the knob body 31 can be designed as an integrated structure, or the end of the clutch block 32 away from the shaft 41 is abutted by the inner side wall of the lock shell 2.

[0045] In the embodiment, the side surface of the base 24 is also provided with two lock holes, each of which is provided with a second lock hook 72. The two second lock hooks 72 are rotatable relative to the base 24. The mounting mode of the second lock hook 72 can refer to the mounting mode of the first lock hook 71. The lock tongue 90 is provided with a through hole 901 matched with the second lock hook 72. In combination with Figure 10 and Figure 11 , the second unlocking mechanism 9 comprises a movable piece 91 and a second lock block 92. The bottom surface of the movable piece 8 extends downwardly with a swing part, and the middle part of the movable piece 91 is provided with a clamping hole 911 for inserting the swing part. In the assembled state, the swing part is inserted into the clamping hole 911. When the movable piece 8 slides to the left or to the right, the movable piece 8 will slide to the left or to the right with the movable piece 91. The two second lock blocks 92 are arranged on the left and right sides of the movable piece 91, and each second lock block 92 is matched with a second lock hook 72. Each second lock block 92 is rotatably mounted in the base 24 through a rotating shaft. The second lock hook 72 is the same as the first lock hook 71. The second lock hook 72 is also provided with a clamping part and a hook part. The movable piece 91 extends a pushing part 912 towards the second lock block 92. The second lock block 92 extends a first swing arm 921 towards the pushing part 912 and a second swing arm 922 towards the clamping part of the second lock hook 72.

[0046] The working process of the second unlocking mechanism 9 is as follows: in the locked state, the lock tongue 90 is inserted into the lock hole. The hook part of the second lock hook 72 buckles the through hole 901 of the lock tongue 90. The movable piece 8 cannot slide. The movable piece 8 limits the sliding of the movable piece 91 through the swing part. The movable piece 91 cannot slide. The pushing part 912 of the movable piece 91 abuts against the first swing arm 921 of the second lock block 92. The second swing arm 922 of the second lock block 92 abuts against the clamping part of the second lock hook 72, thereby limiting the rotation of the second lock hook 72, and achieving the locking. When unlocking, when the movable piece 8 slides to the left or to the right, the movable piece 8 will slide to the left or to the right with the movable piece 91. During the sliding process of the movable piece 91, the pushing part 912 of the movable piece 91 will abut against the first swing arm 921 of the second lock block 92, thereby driving the second lock block 92 to rotate around the rotating shaft. During the rotation process of the second lock block 92, the second swing arm 922 of the second lock block 92 will be separated from the clamping part of the second lock hook 72, thereby releasing the locking of the second lock hook 72, and achieving the unlocking.

[0047] In another embodiment, the second unlocking mechanism 9 and the second lock hook 72 can be selectively replaced according to different use cases, for example, when the multi-layer bag cancels the partition of the first box body 1, and the multi-layer bag is provided with multiple zipper strips that need to be locked, the second lock hook 72 is arranged in the face shell 21, that is, the first lock hook 71 and the second lock hook 72 are symmetrically arranged with the swing button assembly 3 as the symmetric point, the movable piece 91 can be arranged integrally with the movable piece 8, and by arranging inclined surfaces with different inclination directions, the swing of the swing button to the left or right side can control the opening of the lock hook on the left side or the opening of the lock hook on the right side. Therefore, the second unlocking mechanism 9 and the first unlocking mechanism 6 can select different structural forms according to actual needs, and the structure and position of the first lock hook 71 and the second lock hook 72 can also be selected and arranged according to specific conditions. The password lock provided in the embodiment is only one of the implementation manners, and the swing button assembly 3 of the embodiment can be used for various bags.

[0048] In order to further improve the use feeling of the swing button assembly 3, the top end face of the swing button body 31 is provided with elastic protrusions 314 protruding upward on the left and right sides.
