Description

Technical Field

[0001] The present invention relates to the technical field of luggage locks, and more particularly to a luggage lock with an emergency opening function. Background Art

[0002] In the current suitcase and luggage market, combination locks are widely used as mainstream security devices. The design principle of this lock is to achieve the sealing and security protection of the box by fixing two zipper heads together. The original intention of the design of the combination lock is to provide a keyless, convenient and fast opening and closing method. The user only needs to remember the set password combination to operate it. This design does bring a certain convenience in daily use.

[0003] However, this traditional combination lock design also has obvious limitations and potential problems. The most prominent problem is that when the user does not use the suitcase for a long time, it is easy to forget the previously set combination. Once the combination is forgotten, the user will face the dilemma of being unable to open the suitcase due to the lack of a backup opening method. This will not only cause great inconvenience to the user, but may even result in the need to forcibly destroy the lock to remove the items in the suitcase, which significantly reduces the product experience and affects the practical value of the suitcase.

Each telescopic sleeve 214 is respectively provided with no less than four groups of symmetrically arranged pressure plates 215, and each end of each telescopic frame 210 is respectively provided with a transverse rod 216, and the pressure plates 215 are pressed on the transverse rod 216. A plurality of annular rods 217 are evenly spaced on the side of the telescopic sleeve 214 close to the outer sleeve 27, and a plurality of annular grooves 218 corresponding to the annular rods 217 are opened on the outer sleeve 27, and the plurality of annular rods 217 are respectively stuck in the annular grooves 218, and a plurality of push springs 219 are sleeved on the inner sleeve 28, and a plurality of push springs 219 are installed with a follower ring 220, and the follower ring 220 is in contact with the side wall of the telescopic sleeve 214.

[0025] When the password is forgotten while using the suitcase, the two zippers are respectively stuck in the two one-way rods 23 and the slots 21, so the two zippers are fixed. After the password is forgotten, the linkage plate 25 is in a fixed state and cannot be unlocked. At this time, the connection between the two one-way rods 23 and the linkage plate 25 can only be disconnected, and then the one-way rods 23 can be pulled out to disengage the connection, so that the emergency opening function can be achieved.

[0026] See also Figure 3When the connection between the one-way rod 23 and the linkage plate 25 needs to be released, the linkage sleeve 26 and the outer sleeve 27 are in a fixed connection state, and the inner sleeve 28 is in a linkage state with the two one-way rods 23 through the rotation connection between the inner nesting 212 and the outer nesting 213. Figure 5 and Figure 6 , so you only need to untie the connection between the inner sleeve 28 and the outer sleeve 27. When in the connected state, the telescopic frame 210 is slidably connected to the outer groove 29, and the telescopic frame 210 is stuck in the fixing groove 211, thereby fixing the inner sleeve 28 and the outer sleeve 27. When you need to untie the connection between the two, please refer to Figure 10 and Figure 11 When the cam 214 is in the closed position, the push spring 219 is pressed against the locking cam 216 and the locking cam 217 is in the closed position, so that the cam 214 can be locked in the closed position. Figure 6 At this time, the telescopic frame 210 is fitted on the fixed groove 211. As the inner sleeve 28 rotates, the telescopic frame 210 will press against the side wall of the expansion groove 34. Then, as the position of the expansion groove 34 changes, the multiple telescopic frames 210 expand outward, and the annular spring 39 is in a stretched state until it rotates to the position of the vertical groove 38 linked to the expansion groove 34. Then, the telescopic frame 210 is stuck in the vertical groove 38. At this time, the inner sleeve 28 and the outer sleeve 27 are untied in the vertical direction. Therefore, by pulling the untiing rod 31, the inner sleeve 28 can be pulled outward, and then the two one-way rods 23 will move accordingly, thereby untying the connection between the one-way rod 23 and the zipper, thereby completing the emergency opening process.

[0027] When the opening is completed and needs to be reset, since the release rod 31 is still inserted in the internal sleeve 28, the internal sleeve 28 is pushed so that the one-way rod 23 is pressed against the card slot 21. At this time, the internal sleeve 28 is limited, and the telescopic frame 210 slides along the vertical slot 38 to the position of the expansion slot 34, and then drives the release rod 31 to rotate in the opposite direction, so that the telescopic frame 210 is stuck in the expansion slot 34. The tension provided by the multiple annular springs 39 makes the multiple telescopic frames 210 always in a tightened state, and rotates The telescopic frame 210 is stuck in the fixed groove 211, and is in a fixed state when it fits into the other end of the fixed groove 211. Then continued rotation will cause the stop block 32 to disengage from the stop groove 33. At this time, the disengagement rod 31 is pulled outward, and the push spring 219 is reset. Then the telescopic sleeve 214 is pressed against the outer sleeve 27, and the limit is ensured by the annular rod 217 and the annular groove 218, and the pressure plate 215 is pressed on the transverse rod 216, thereby ensuring the stability of the card connection, thereby completing the entire use process.
