[0018] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-4As shown, a luggage customs lock includes an upper shell 1 and a lower bottom 2. A lock slot 11, a lock hole 12 and a password toggle slot 13 are provided on the surface of the upper shell 1. The lower bottom 2 is fixed to the surface of the luggage by a threaded hole or 3M adhesive. The upper shell 1 and the lower bottom 2 are fixedly connected. The two cooperate to form a cavity. A panel 3 is provided in the cavity. The panel 3 is provided with a lock tongue moving component 4, a lock core 5, a password lock component 6 and a rotatably connected locking block 7. The above structures are all arranged on the panel 3, so that the overall structure of the utility model is compact and the volume is small, which is convenient for installation on smaller luggage.

[0020] The lock tongue moving assembly 4 includes a sliding switch 41 and a lock tongue bracket 42. The upper surface of the sliding switch 41 is provided with an arrow mark 411 indicating the sliding direction. The sliding switch 41 and the lock tongue bracket 42 are fixedly connected. Two lock tongues 43 are fixed on the lock tongue bracket 42. The position and number of the lock tongues 43 correspond one-to-one to the lock slots 11 on the upper shell 1. The rear end of the lock tongue 43 is connected to a compression spring 44. The other end of the compression spring 44 is fixed to the support plate 45 in the upper shell 1. A spring piece 46 is fixed under the lock tongue 43. The lock tongue moving assembly 4 is used to lock and unlock the zipper head of the luggage. When the user pushes the sliding switch 41 in the direction indicated by the arrow mark 411, the lock tongue bracket 42 moves, the lock tongue 43 is removed from the zipper head of the luggage, and the spring piece 44 pushes upward to push out the zipper head of the luggage that was originally locked in the lock slot 11.

[0021] The lock cylinder lever 51 provided at the lower end of the lock cylinder 5 pushes the locking block 7 to rotate to unlock the lock tongue moving assembly 4; the combination lock assembly 6 is installed below the combination dial groove 13, and the combination lock assembly 6 includes a combination wheel 61 and a movable plate 62. The center of the combination wheel 61 is connected with a plug column 63 fixed at the top in the upper shell 1. The combination wheel 61 includes a code wheel 611 and a number wheel 612. The bottom of the number wheel 612 is integrally provided with a plurality of protrusions 613, and the plurality of protrusions 613 are embedded in the surface of the code wheel 611. The surface of the coding wheel 611 is provided with a card slot 614, and the movable plate 62 is integrally provided with a movable plate protrusion 621 and a combination lock lever 622. A movable plate spring 64 is fixedly connected between the end surface of the movable plate 62 away from the combination lock lever 622 and the spring seat 65. When the card slot 614 is rotated to a position opposite to the movable plate protrusion 621, the movable plate spring 64 pushes the movable plate protrusion 621 to snap into the card slot 614, and the combination lock lever 622 pushes the locking block 7 to rotate to unlock the lock tongue moving assembly 4.

[0022] The locking block 7 includes an integrally connected base 75, a first stop lever 71 and a second stop lever 72. The base 75 is rotatably connected to the panel 2. A return spring 74 is fixedly provided on the spring column 73 of the panel 2. The other end of the return spring 74 abuts against the base 75. The second stop lever 72 is pushed by the password lock lever 622 of the password lock assembly 6 or the lock cylinder lever 51 of the lock cylinder 5. The second stop lever 72 rotates so that the first stop lever 71 and the lock tongue bracket 42 are not in the same horizontal position, making way for the lateral movement of the lock tongue bracket 42. When the password lock assembly 6 and the lock cylinder 5 are in the locked state, as shown in FIG. Figure 4 As shown, the lock cylinder lever 51 is in a non-contact state with the second shift lever 72, the card slot 614 on the coding wheel 611 is not aligned with the movable plate protrusion 621 on the movable plate 62, and the movable plate protrusion 621 is supported by the coding wheel 611, thereby driving the combination lock lever 622 on the movable plate 62 away from the second shift lever 72. At this time, the first shift lever 71 is in the same horizontal position as the lock tongue bracket 42 under the action of the return spring 74, limiting the lateral movement of the lock tongue bracket 42, thereby realizing the locking function of the lock tongue 43.

[0023] like Figure 5 As shown, when the key is inserted into the lock cylinder 5 and rotated, the lock cylinder 5 drives the lock cylinder lever 51 to rotate synchronously, and the lock cylinder lever 51 pushes the second gear lever 72 to rotate, so that the first gear lever 71 and the lock tongue bracket 42 are not in the same horizontal position, and the lateral movement of the lock tongue bracket 42 is no longer restricted. The lock tongue 43 is in an unlocked state, and the lock tongue 43 can be unlocked by pushing the sliding switch 41.

[0024] like Figure 6 As shown, when the lock cylinder 5 is in the non-unlocked state, it is unlocked through the combination lock assembly 6, the combination dial groove 13 rotates the combination wheel 61 to the correct digital combination position, the card slot 614 on the surface of the coding wheel 611 is aligned with the movable plate boss 621 on the movable plate 62 and fits into each other, causing the movable plate 62 to move horizontally, and the combination lock dial rod 622 at the end of the movable plate 62 pushes the second gear lever 72 to rotate, so that the first gear lever 71 and the lock tongue bracket 42 are not in the same horizontal position, and the sliding switch 41 is pushed to complete the unlocking operation of the lock tongue 43.

[0025] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
