Description

Technical Field

[0001] This utility model relates to a dual-channel padlock with indicator markings. Background Technology

[0002] Existing dual-channel padlocks have obvious markings indicating whether they have undergone customs inspection. This makes it easy for security personnel to miss or double-check the items, while passengers are unsure whether their luggage has been inspected and often need to attach additional inspection marks, causing unnecessary trouble. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a dual-channel padlock with a simple structure and built-in check prompt.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a double-channel padlock with indicator markings, comprising a lock case and a lock beam. The lock case contains a combination lock assembly, a customs lock assembly, an unlocking button, an unlocking lever, and a lock cylinder. The lock case has an indicator through-hole and an indicator lever. The unlocking lever and the indicator lever are hinged to the lock case. The indicator lever has a combination lock indicator area and a customs lock indicator area. The combination lock indicator area and the customs lock indicator area rotate back and forth around the hinge point with the indicator lever, alternately corresponding to and engaging with the indicator through-hole. One end of the unlocking button protrudes from the outside of the lock case, and the other end of the unlocking button has an unlocking end and a reset end. The unlocking end engages with the unlocking lever and pushes the unlocking lever to press the lock cylinder, releasing the locking restriction on the lock beam. The reset end engages with the indicator lever. The system pushes the indicator lever to swing. An opening ramp is located below the opening button. The combination lock assembly includes a combination wheel assembly and a combination lock lever. When the combination wheel assembly is locked, it restricts the downward movement of the combination lock lever. The combination lock lever has a pushing ramp that engages with the opening ramp. The customs lock assembly includes a customs lock cylinder and a customs key. The customs key opens the customs lock cylinder and rotates it. The customs lock cylinder has a long, narrow protrusion. One end of the long, narrow protrusion engages with the opening lever and pushes the opening lever to press the lock head, releasing the locking restriction on the lock beam. The other end of the long, narrow protrusion is connected to a "U"-shaped hook. One end of the hook engages with the long, narrow protrusion, and the other end engages with the indicator lever, causing the indicator lever to swing as the long, narrow protrusion rotates.

[0005] The beneficial effects of this utility model are: by distinguishing the combination lock indicator area and the customs lock indicator area on the indicator lever (which could be due to different materials or colors), and by exposing different indicator areas through marked through holes on the lock shell, it is possible to clearly and intuitively show whether the lock was last opened using a customs key or a combination lock. This allows for the determination of whether the lock has been inspected by security personnel using a customs key and whether it has been reopened using a combination lock. The specific working principle is: when the combination lock group is locked, the combination lock cylinder restricts the combination lock lever. Moving downwards, the inclined surface of the combination lock lever engages with the inclined surface below the unlocking button, restricting the button's opening. In this state, the customs key unlocks the customs lock cylinder. Rotating the customs lock cylinder causes one end of the elongated protrusion on it to engage with the lower end of the unlocking lever, pushing the lower end of the unlocking lever to rotate around the hinge point on the lock case. The upper end of the unlocking lever then pushes the lock head in a direction that disengages from the locking girders, disengaging the locking girders from the lock head, thus unlocking the lock with the customs key. During this process, the other end of the elongated protrusion engages with the "U"-shaped... The hooks work together, hooking the "U"-shaped hook block outwards. The other end of the "U"-shaped hook block then hooks the lower end of the indicator lever, causing the indicator lever to swing around the hinge point. This ultimately exposes the indicator area of ​​the customs lock outside the marked through-hole. When the combination lock is opened again, the combination wheel assembly releases the restriction on the downward movement of the combination lock lever. Pushing the unlock button inwards, the inclined surfaces of the unlocking and pushing surfaces engage, causing the combination lock lever to move downwards. Simultaneously, the unlock button moves inwards into the lock housing, and the unlocking end on the unlock button pushes the upper end of the unlocking lever around the hinge on the lock housing. The hinge point rotates, and then the upper end of the opening rod pushes the lock head to move in the direction of disengaging from the locking engagement with the lock beam, so that the lock beam disengages from the locking engagement with the lock head, achieving the combination lock opening state. During this process, the reset end on the opening button pushes the upper end of the prompt lever, causing the prompt lever to swing around the hinge point, eventually returning to the combination lock prompt area exposed outside the marked through hole. Regardless of whether the combination lock is opened or locked multiple times, the prompt area remains in the state of exposing the marked through hole until the customs key is used to open the customs lock assembly again, at which point the area exposed outside the marked through hole will become the customs lock prompt area.

[0006] Furthermore, the combination lock's indicator area has a green coating, while the customs lock's indicator area has a red coating. These different colored indicator areas are exposed through the marked holes. If the exposed area is red, it indicates that the lock was last opened by security personnel using a customs key. If the exposed area is green, it indicates that the lock was last opened using a combination lock, making the information more intuitive and clear. Attached Figure Description
