Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a swing-type luggage linkage lock. Background Technology

[0002] With the increasing demand for luggage for work, travel, and business trips, various types of bags have become increasingly important in people's lives. People often put valuables and documents in their bags for easy carrying. Therefore, the security and theft prevention of bags are receiving more and more attention, and bag locks have become an indispensable component of bags.

[0003] A combination lock, as disclosed in Chinese patent document CN205012764U, includes a central control lock, a first side lock, and a second side lock. The first side locks are located at both ends of the central control lock. The first and second side locks are controlled by a rotating block and a steel wire rope. The central control lock controls the opening and closing of the first and second side locks through its internal central control transmission mechanism. The first latch of the central control lock, the first latch of the first side lock, and the second latch of the second side lock are fixed to the frame of one opening side of the lock body. The first hook of the first side lock and the second hook of the second side lock are fixed to the frame of the other opening side of the lock body. Controlling the opening and closing of multiple side locks through the central control transmission mechanism enhances the security of the combination lock. Because the central control transmission mechanism has fewer transmission components and a simpler transmission relationship, the stability and reliability of the combination lock's transmission are more reliable, and the combination lock is easier to assemble.

[0004] The inventors then developed a centrally controlled multi-linkage luggage lock, as disclosed in Chinese patent document CN221169095U. This lock includes a central lock and two or more side locks on the same side outside the central lock. The central lock comprises a lock housing, a locking mechanism, and a transmission component. The locking mechanism is mounted on the lock housing, and the transmission component is mounted on the lock housing and restricted by the locking mechanism. The transmission component can only move after the correct command is input into the locking mechanism. Each side lock includes a lock body, a latch, and a hook. The latch is movably mounted on the lock body to engage the hook. The transmission component and the latch, as well as the latches of different side locks, are connected by steel cables. This allows the movement of the transmission component to drive the latches of each side lock via the steel cables, thereby disengaging and unlocking them from their corresponding hooks. Because two or more interconnected side locks are located on the same side of the central lock, two or more side locks can be used to lock the same side of the luggage, or more sides of the luggage can be locked.

[0005] The side lock and the central lock are linked by a steel rope. The central lock pulls the steel rope by pushing and sliding the transmission components. That is, the pushing and sliding distance is basically the same as the movement distance of the inner core of the steel rope, which restricts the sliding stroke of the steel rope. Summary of the Invention

[0006] In view of the above-mentioned technical problems, the present invention provides a swing-type luggage linkage lock.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A swing-type luggage interlocking lock is provided, comprising a main lock body, a secondary lock body, and a steel rope. The main lock body includes a lock housing, a transmission component, and a locking mechanism. The transmission component is slidably installed within the lock housing and is linked to a secondary lock hook within the secondary lock body via the steel rope. Its characteristic is:

[0009] The main lock body also includes a swing shell and a pry bar. The pry bar is fixed to the end of the swing shell, and the swing shell is hinged to the lock shell near the end. In the locked state, the locking mechanism restricts the swing shell from rotating and tilting.

[0010] When unlocking, after the correct command is input into the locking mechanism, the swing shell can be tilted up and the pry bar can be used to slide the transmission component, thereby pulling the steel rope and unlocking the secondary lock hook.

[0011] Specifically, the swing shell is provided with a push mechanism, the push mechanism is provided with a limit hook, and the lock shell is provided with a locking part; in the locked state, the locking mechanism limits the push mechanism, so that the limit hook is kept locked to the locking part to prevent the swing shell from tilting up; when unlocking, after the limit on the push mechanism is released, the external force pushes the push mechanism, so that the limit hook is separated from the locking part.

[0012] Specifically, the lock housing includes a first housing and a second housing, both of which are enclosed at the bottom and around the sides and open at the top. The transmission component is slidably installed inside the bottom of the first housing, and a steel rope passes through the end of the first housing to connect to the transmission component. The second housing is embedded in the first housing and located above the transmission component. The locking mechanism is installed on the swing housing, which is installed on the second housing. The holding part is located inside the second housing.

[0013] Specifically, the second housing, the swing housing, the pry bar, the locking mechanism, and the pusher form an independent module. This module is embedded in the first housing as a whole, and the pry bar is installed on the outer side of the swing housing to abut against the transmission component.

[0014] Specifically, the end of the first housing is provided with a main lock hook that is linked to the transmission component. When unlocking, the transmission component slides to unlock the main lock hook.

[0015] Specifically, the swing shell is provided with a directional rail, and the pusher is provided with a directional groove. The directional rail is embedded in the directional groove so that the pusher slides in a directional manner.

[0016] Specifically, the locking mechanism includes a combination component and a key component. The key component includes a lock cylinder mounted on the push mechanism and a long, narrow lock block. The lock block is mounted on the bottom of the lock cylinder and rotates together with each other. The combination component includes a set of wheels and a center rod, with the center rod passing through multiple sets of wheels. In the locked state, the lock cylinder is fixed relative to the push mechanism, and the end of the lock block abuts against the center rod. When unlocking with the key, inserting the correct key rotates the lock cylinder and the lock block, creating space between the lock block and the center rod. When unlocking with the combination, the center rod can only move axially to create space after the set of wheels has rotated to the correct combination.

[0017] Specifically, the swing shell is provided with an assembly groove, the skid is partially embedded in the assembly groove, and the hinge shaft of the swing shell passes through the skid for positioning.

[0018] Specifically, the skid includes a U-shaped beam and arm sections at both ends of the beam. The beam is fitted into an assembly slot and has an assembly hole through which the hinge shaft of the swing shell passes. The arm section has a column section that abuts against the transmission component.

[0019] Specifically, the lock housing is equipped with an elastic element that applies force to the transmission components in the reset direction.

[0020] The beneficial effects of this utility model are:

[0021] This utility model discloses a swing-type luggage linkage lock. Compared with the prior art, the swing shell rotates and tilts up, causing the pry bar to slide against the transmission component, thereby pulling the steel rope to unlock the secondary lock hook. The rotational stroke of the pry bar following the rotation of the swing shell is larger than that of the existing linear transmission, which more effectively drives the steel rope to move and unlock smoothly.

[0041] 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.

[0042] This embodiment provides a swing-type luggage linkage lock, such as... Figures 1 to 6 As shown, it includes a main lock body 100, a secondary lock body 200, and a steel rope 9. The main lock body 100 includes a lock shell 1, a transmission component 5, and a locking mechanism 6. The transmission component 5 is slidably installed inside the lock shell 1. The transmission component 5 is linked with the secondary lock hook inside the secondary lock body 200 via the steel rope 9. The steel rope 9 being pulled to drive the secondary lock hook to unlock is existing technology and will not be elaborated here.

[0043] In this embodiment, the main lock body 100 also includes a swing shell 2 and a pry block 3. The pry block 3 is fixed to the end of the swing shell 2, and the swing shell 2 is hinged to the lock shell 1 near that end. In the locked state, the locking mechanism 6 restricts the rotation of the swing shell 2, such as... Figure 1 and 4 The state shown.

[0044] When unlocking, after entering the correct command into the locking mechanism 6, such as... Figure 5 and Figure 6The device shown can cause the pendulum shell 2 to swing and tilt, causing the pry bar 3 to slide the transmission component 5, which in turn pulls the steel cable 9 to unlock the secondary lock hook. The correct commands are a password and a key, which will be detailed later.

[0045] Specifically, the swing shell 2 is slidably provided with a pusher 4, the pusher 4 is provided with a limiting hook 41, and the lock shell 1 is provided with a retaining part 13. In the locked state, the locking mechanism 6 limits the pusher 4, keeping the limiting hook 41 locked to the retaining part 13 to prevent the swing shell 2 from tilting. When unlocking, after the locking mechanism 6 releases the limiting of the pusher 4, external force pushes the pusher 4, causing the limiting hook 41 to separate from the retaining part 13, and the swing shell 2 can then rotate and tilt.

[0046] Specifically, the lock housing 1 includes a first housing 11 and a second housing 12, both of which are enclosed at the bottom and all four sides, with an open top. A transmission component 5 is slidably installed inside the bottom of the first housing 11, and a steel rope 9 passes through the end of the first housing 11 and secures the transmission component 5. The second housing 12 is embedded inside the first housing 11 and located above the transmission component 5. A locking mechanism 6 is installed on a swing housing 2, which is installed on the second housing 12. The retaining part 13 is located inside the second housing 12. During assembly, the second housing 12, swing housing 2, pry bar 3, locking mechanism 6, and pusher 4 are assembled into an independent module. This module is entirely embedded in the first housing 11, and the pry bar 3 is installed on the outer side of the swing housing 2, abutting against the transmission component 5.

[0047] Specifically, the end of the first housing 11 is provided with a main lock hook 7 that is linked to the transmission component 5. When unlocking, the transmission component 5 slides to unlock the main lock hook 7. The unlocking mechanism of the transmission component 5 and the main lock hook 7 is existing technology and will not be described in detail here.

[0048] Specifically, the swing shell 2 is provided with a directional rail 21, and the pusher 4 is provided with a directional groove 42. The directional rail 21 is embedded in the directional groove 42 so that the pusher 4 slides in a directional manner.

[0049] Specifically, the locking mechanism 6 includes a combination key assembly 61 and a key assembly 62. The key assembly 62 includes a lock core 621 mounted on the push mechanism 4 and a long, narrow locking block 622. The locking block 622 is mounted on the bottom of the lock core 621 and rotates together with it. The combination key assembly 61 includes a set of wheels 611 and a central rod 612, with the central rod 612 passing through multiple sets of wheels 611. In the locked state, the lock core 621 is fixed relative to the push mechanism 4, and the short side of the locking block 622 abuts against the central rod 612, thus restricting the movement of the push mechanism 4. The combination key and the key serve as the correct commands. When unlocking, inserting the correct key rotates the lock core 621 and the locking block 622, causing the long side of the locking block 622 to face the central rod 612. This creates distance between the central rod 612 and the locking block 622, allowing space for the push mechanism 4 to move between them, and external force can then push the push mechanism 4. When unlocking the combination lock, the center rod 612 can only move axially after the wheel assembly 611 is rotated to the correct combination, thus allowing the pusher 4 to be activated. The relationship between the wheel assembly 611 and the center rod 612 of the combination lock assembly 61 is existing technology and will not be elaborated upon here.

[0050] Specifically, the swing shell 2 is provided with an assembly groove 22, and the pry bar 3 is partially embedded in the assembly groove 22, and the hinge shaft of the swing shell 2 passes through the pry bar 3 for positioning. Specifically, the pry bar 3 includes a beam portion 31 that is generally U-shaped and arm portions 33 located at both ends of the beam portion 31. The beam portion 31 is embedded in the assembly groove 22, and the beam portion 31 is provided with an assembly hole 32 for the hinge shaft of the swing shell 2 to pass through. The arm portion 33 is provided with a column portion 34 that abuts against the transmission component 5.

[0051] Specifically, the lock housing 1 is equipped with an elastic element 8 that applies force to the transmission component 5 in the reset direction. In this embodiment, a block abuts against the transmission component 5, and a spring applies force to this block, indirectly applying a reset force to the transmission component 5. Of course, in practice, the spring can directly abut against the transmission component 5. This can reduce the force required to press down the swing housing 2, improving the user experience. Furthermore, if the elastic force is large enough, after the external force lifts the swing housing 2, the swing housing 2 and the transmission component 5 can automatically reset under the action of the elastic force.
