Description
Technical Field
[0001] This utility model relates to the field of lock technology, specifically to a lanyard lock. Background Technology
[0002] Wire rope locks are a type of lock known for their high security and durability. Typically made of high-strength steel wire rope, they offer excellent wear and corrosion resistance, maintaining good working condition for extended periods. Compared to traditional metal chain locks, wire rope locks are more flexible, adapting to items or equipment of various shapes and sizes. This makes them more convenient to use and better suited to different application scenarios.
[0003] For example, Chinese patent document CN221627943U discloses a TSA customs lock with anti-loss positioning function, including a shell, PCBA mounting plate, PCBA board, lock cylinder device, battery device, reset component, and lanyard component. The beneficial effects of this utility model are: simple structure, easy to operate, and anti-loss positioning function, which realizes the detection of lock body locking, unlocking or illegal use, etc. At the same time, the lock body positioning status can be known in real time through mobile phone, which is convenient for real-time monitoring of the lock body position. It can also better find the lock body position through positioning and calling sound, eliminating the complicated process of queuing to pick up, registering locking and unlocking each time.
[0004] For example, Chinese patent document CN210122856U discloses a luggage lock with illumination that prevents loss. Its structure includes a lock body, a combination wheel, a TSA lock hole, a TSA mark, a lanyard hole, a lanyard, a combination reset button, and a positioning lighting device. The rear end of the combination wheel is rotatably connected to the lower front end of the lock body. The TSA lock hole is located on the upper front end of the lock body. The rear end of the TSA mark is glued to the upper right side of the front end of the lock body. This luggage lock with illumination prevents loss by setting up a positioning lighting device. The positioning chip locates the position of the luggage lock, and the wireless module sends the information to a smartphone for real-time tracking to prevent loss. It also has a side light for illumination at night, solving the problems of lost luggage or accidental theft at the airport, and the danger of walking at night without a light.
[0005] For example, Chinese patent document CN209457587U discloses a padlock including a lock case and a U-shaped hook. The hook has an unlocked position and a locked position. It also includes a movable component, a button, a combination lock, and a lock cylinder installed within the lock case. The button is movably connected to the movable component. The combination lock has a dial and a movable frame. In the locked state, the dial restricts the movement of the movable frame. When the combination is correct, the restriction on the movable frame is released, allowing the button to push the movable frame and simultaneously drive the movable component to switch the hook to the unlocked position. The lock cylinder can rotate along its axial direction, pushing the movable component to switch the hook to the unlocked position. When the combination is correct, the lock is unlocked by pressing the button to open the movable component. When using a key, the lock cylinder is directly rotated to pull the movable component. The lock cylinder and the combination lock operate completely separately and independently, providing convenience for later maintenance and reducing assembly difficulty.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0037] One embodiment of this embodiment is a lanyard lock, such as Figures 1 to 5 As shown, the device includes a lock housing 1, a tracker, a locking cord 2, a combination lock assembly 3, and a key assembly 4. A storage cavity 11 is provided in the middle of the lock housing 1, and the tracker is fixed in the storage cavity 11. The tracker is not shown in the figure. It should be noted that the tracker is used for communication and tracking with a mobile terminal. This embodiment only optimizes its installation position; its principle and structure are existing technology and will not be elaborated here. The combination lock assembly 3 and the key assembly 4 are respectively installed on both sides of the storage cavity 11.
[0038] In this embodiment, the lock housing 1 is provided with a first lock sleeve 5 and a second lock sleeve 6, which are installed on the top of the lock housing 1. The first lock sleeve 5 is provided with a first lock hole 51, and the second lock sleeve 6 is provided with a second lock hole 61. The lock rope 2 includes a rope body 21 and a first lock head 22 and a second lock head 23 fixed to both ends of the rope body 21. The first lock head 22 is inserted into the first lock hole 51 and locked by the combination component 3. After entering the correct combination, the restriction on the first lock head 22 can be released, allowing it to detach from the first lock hole 51. The second lock head 23 is inserted into the second lock hole 61 and locked by the key component 4. After inserting the correct key, the restriction on the second lock head 23 can be released, allowing it to detach from the second lock hole 61.
[0039] Specifically, the first lock hole 51 is an irregularly shaped hole, gourd-shaped, with one side larger than the other. It includes an adjacent through-hole 511 and a limiting hole 512. The through-hole 511 is larger, and the limiting hole 512 is smaller. The first lock head 22 is similar to a lollipop shape. The first lock head 22 can disengage at the through-hole 511, but cannot disengage at the limiting hole 512. A stop block 7 is provided inside the lock case 1 corresponding to the first lock hole 51. When locking, the first lock head 22 is inserted from the through-hole 511 and moves into the limiting hole 512, where it is pressed against the stop block 7. The combination component 3 limits the stop block 7 to prevent the first lock head 22 from moving into the through-hole 511. When unlocking, after entering the correct combination, the restriction on the stop block 7 is released, and the first lock head 22 can move into the through-hole 511 and disengage.
[0040] Specifically, the top of the stop block 7 is provided with a guide slope 71 so that the first lock head 22 is guided to the limiting hole 512 after being inserted from the insertion hole 511.
[0041] Specifically, the combination component 3 includes a central rod 31, multiple combination wheels 32, and multiple adjustment wheels 33. The combination wheels 32 are rotatably mounted on the lock housing 1 and partially exposed. The multiple adjustment wheels 33 are coaxially mounted within the multiple combination wheels 32, and rotate together with their corresponding combination wheels 32. The central rod 31 passes through the multiple adjustment wheels 33 and connects to the stop block 7. The central rod 31 can only move axially after the multiple combination wheels 32 have rotated to the correct combination. The central rod 31 drives the stop block 7 to move and make room, so that the first lock head 22 can be moved to the insertion hole 511 and pulled out to unlock.
[0042] Specifically, the key assembly 4 includes a lock core 41 and a lock block 42. The lock block 42 is fixed to the end of the lock core 41. When the correct key is inserted into the lock core 41 and the lock core 41 is rotated, the lock block 42 can be rotated. The lock block 42 is provided with a locking protrusion 421, and the second lock head 23 is provided with a locking groove 231. In the locked state, the locking protrusion 421 is engaged in the locking groove 231 to prevent the second lock head 23 from disengaging from the second keyhole 61. In the unlocked state, the locking protrusion 421 moves out of the locking groove 231 to release the restriction on the second lock head 23. It can be seen that the end of the lock block 42 is an irregular concave-convex structure, and rotation can achieve locking and unlocking of the second lock head 23.
[0043] Specifically, the lock housing 1 includes a first housing 12, a second housing 13, a first cover 14, and a second cover 15. The inner side of the first housing 12 has a groove for installing the combination key assembly 3 and the key assembly 4. The first cover 14 is fixed to the first housing 12 with screws and covers the combination key assembly 3. The second cover 15 is fixed to the first housing 12 with screws and covers the key assembly 4. The first housing 12 and the second housing 13 are fastened together. During installation, the combination key assembly 3 is first fixed to the first housing 12 through the first cover 14, and the key assembly 4 is fixed to the first housing 12 through the second cover 15 to form a module. Then, the second cover 15 is fixed to cover this module, making assembly convenient.
