The luggage lock provided by the present application is arranged on the luggage main body. The luggage lock includes a lock housing 101, a lock cylinder 102, a password unlocking mechanism 103, and a dial unlocking mechanism 104. The lock housing 101 is arranged on the luggage main body. The password unlocking mechanism 103 and the dial unlocking mechanism 104 are respectively arranged at two ends of the length direction of the lock housing 101. The lock cylinder 102 is arranged between the password unlocking mechanism 103 and the dial unlocking mechanism 104. The lock cylinder 102 and the password unlocking mechanism 103 unlocked by the lock cylinder 102 are both prior art and will not be described in detail.

[0032] The dial unlocking mechanism 104 includes a rotating block 1041 and a sliding block 1042. The rotating block 1041 is arranged on the lock cylinder 102 and can rotate together with the lock cylinder 102 when the lock cylinder 102 rotates. The sliding block 1042 is arranged in the lock housing 101. An insertion slot 10422 is arranged on the sliding block 1042. An insertion rod 10411 capable of being inserted into the insertion slot 10422 is arranged on the rotating block 1041. When the lock cylinder 102 rotates around its own axis in one direction, the sliding block 1042 can be driven to move away from the password unlocking mechanism 103. When the lock cylinder 102 rotates around its own axis in the opposite direction, the sliding block 1042 is driven to move towards the password unlocking mechanism 103.

[0033] The traction rope 3 is connected to the sliding block 1042, and the end of the traction rope 3 away from the sliding block 1042 is provided with the first side lock 2. When the sliding block 1042 is moved towards the password unlocking mechanism 103 under the driving of the rotating block 1041, the first side lock 2 can be unlocked. When the sliding block 1042 is moved away from the password unlocking mechanism 103 under the driving of the rotating block 1041, the first side lock 2 is in a locked state.

[0034] More specifically, the first side lock 2 includes a fixed seat 201, a locking driving member 202, and a locking executing member 203. The fixed seat 201 is fixedly arranged on the fixed frame 8, and the locking driving member 202 and the locking executing member 203 are arranged in the fixed seat 201, respectively. The locking driving member 202 includes a connecting rod 2021 and a driving block 2022 fixedly arranged on the connecting rod 2021. The locking executing member 203 includes a locking tongue 2031, a first mounting seat 2032, and an unlocking block 2033. The locking tongue 2031 is arranged in the first mounting seat 2032 and vertically extends from the first mounting seat 2032 in a natural state to achieve locking between the fixed frame 8 and the rear cover plate 7. The unlocking block 2033 is also arranged in the first mounting seat 2032 and is perpendicular to the locking tongue 2031. One end of the unlocking block 2033 is connected to the traction rope 3. A first wedge surface is arranged on the unlocking block 2033, and a second wedge surface capable of abutting the first wedge surface is arranged on the locking tongue 2031. When the traction rope 3 pulls the unlocking block 2033 to move on the first mounting seat 2032, the unlocking block 2033 moves in a direction perpendicular to the length of the locking tongue 2031. In this process, the second wedge surface on the locking tongue 2031 and the first wedge surface on the unlocking block 2033 slide relative to each other. At this time, the end of the locking tongue 2031 extending from the first mounting seat 2032 is retracted from the first mounting seat 2032, thereby achieving unlocking between the fixed frame 8 and the rear cover plate 7.

[0035] Further, a spring can also be arranged in the first mounting seat 2032. One end of the spring is fixedly connected in the fixed frame 8, and the other end of the spring is used to abut the end of the locking tongue 2031 in the fixed frame 8. This makes the locking tongue 2031 be pushed out of the first mounting seat 2032 under the action of the spring force when the sliding block 1042 moves away from the password unlocking mechanism 103. At the same time, the unlocking block 2033 slides to the original position, thereby achieving locking between the fixed frame 8 and the rear cover plate 7 again.
