Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a compact and highly secure bag lock. Background Technology

[0002] With the development of society and economy, people have more opportunities to travel, and the use of luggage is becoming more and more frequent. In order to ensure the privacy and security of luggage, many luggage are equipped with combination locks. For example, Chinese patent document with application number 201320464356.1, entitled "A Combination Lock for Luggage," discloses a luggage lock comprising a housing with a hook opening. The housing contains a combination wheel, a hook, and a hook reset device. A spring is connected to the rear of the hook, extending the hook into the hook opening. The hook reset device pushes the hook away from the hook opening. The combination wheel can reciprocate to push a positioning block, which restricts the movement of the hook. The hook reset device includes a pressing block, a first push rod, and a second push rod. One end of the pressing block is hinged to the housing, and its pressing portion extends outside the housing. One end of the first push rod is hinged to the housing, and the other end is hinged to the second push rod. The second push rod pushes the hook, and the pressing block presses the hinge point between the first and second push rods.

[0003] For example, Chinese patent document CN207513338U discloses a novel bag lock, including a housing and a lock cylinder assembly, a key-changing assembly, and a latch assembly disposed inside the housing. The housing includes a front panel and a back cover, which are interlocked to form an accommodating space for accommodating the lock cylinder assembly, the key-changing assembly, and the latch assembly. The key-changing assembly and the latch assembly are axially parallel and arranged side by side within the accommodating space. The lock cylinder assembly is located at one end of the key-changing assembly and the latch assembly, and its axial direction is vertical. The lock cylinder assembly abuts against both the key-changing assembly and the latch assembly. When an incorrect password is entered into the key-changing assembly, the lock cylinder assembly cannot move along the axial direction of the key-changing assembly. When a correct password is entered into the key-changing assembly, the lock cylinder assembly can move along the axial direction of the key-changing assembly, thereby causing the latch assembly to move along its own axial direction to unlock. The rotation of the lock cylinder assembly can cause the latch assembly to move along its own axial direction to unlock.

[0004] For push-button locks, the combination lock is used to unlock by pressing the button, which pushes against the latch plate; the key lock is used to unlock by rotating the lock cylinder, causing a protrusion at the bottom to push against the latch plate. Since both combination and key unlocking methods need to be independent, the latch plate needs a long slot to prevent one method from interfering with the other. However, this structure, due to the space of the long slot, leaves the latch plate in a movable state (relying on a spring for positioning). If the bag is intentionally dropped or accidentally tipped over, the spring force can easily overcome the latch plate, causing it to move and unlock, thus reducing the security performance of the bag lock. Furthermore, the internal structure layout of existing bag locks is not entirely efficient, requiring a large space to accommodate the complex structure, resulting in a large lock body size. Utility Model Content

[0005] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a compact and highly secure bag lock.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0042] 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.

[0043] This embodiment presents a compact, high-security bag lock, such as... Figures 1 to 4As shown, the lock assembly includes a lock housing 1, a lock hook 2, a latch plate 3, a button 4, a combination lock assembly 6, and a lock cylinder 7. The lock housing 1 has a keyhole 11. The lock hook 2 is movably installed inside the lock housing 1, corresponding to the keyhole 11. The latch plate 3 is slidably installed inside the lock housing 1 to unlock the lock hook 2. The button 4 is elastically installed on the lock housing 1 via a bottom spring and partially protrudes outside the lock housing 1. The lock cylinder 7 is installed at the button 4. The combination lock assembly 6 includes a center rod 61, multiple combination wheels 62, and multiple dialing wheels 63. The dialing wheels 63 are installed one-to-one within the multiple combination wheels 62. The center rod 61 passes through the multiple dialing wheels 63 and is parallel to the latch plate 3. The center rod 61 can only move axially after the multiple combination wheels 62 have turned to the correct combination. Entering the correct combination or inserting the correct key into the combination lock assembly 6 and turning the lock cylinder 7 can operate the button 4 or turn the lock cylinder 7 to slide the latch plate 3 and push the lock hook 2 to unlock. These structures are the basic structures of existing bag locks, and are also included in this embodiment, so they will not be described in detail. The main improvement is as follows:

[0044] Button 4 is provided with a stop block 5, which is flat and elliptical. The bottom of the stop block 5 is provided with a cylindrical limiting protrusion 51 off the rotation center. The latch plate 3 has an elongated relief hole 31 perpendicular to its sliding direction. The limiting protrusion 51 is inserted into the relief hole 31. The limiting protrusion 51 can move along the length direction in the relief hole 31, but can hardly move in the width direction of the relief hole 31, so that the limiting protrusion 51 locks the latch plate 3 in the locked state.

[0045] The top of the stop block 5 is provided with a long strip-shaped stop groove 52, and the bottom of the lock core 7 is embedded in the stop groove 52. The lock core 7 and the stop block 5 rotate together, and the stop block 5 can move relative to the lock core 7 along the length direction of the stop groove 52.

[0046] When unlocking with a combination, the combination wheel 62 rotates to the correct combination, and external force presses button 4, causing the center rod 61 to move. The center rod 61 then causes the bolt plate 3 and the stop block 5 to slide and unlock. When unlocking with a key, the correct key is inserted and the lock cylinder 7 is turned, causing the stop block 5 to rotate. The limiting protrusion 51 of the stop block 5 causes the bolt plate 3 to slide and unlock.

The inner support 42 is provided with a first inclined portion 421 that extends through the upper support 43, and the central rod 61 is provided with a second inclined portion 611, with the first inclined portion 421 abutting against the second inclined portion 611.

[0049] Specifically, the groove wall of the slot 411 is arranged through, so that the stop block 5 can pass through the lower support 41.

[0050] Specifically, the lock tongue plate 3 has a relief hole 32 in the middle, and the center rod 61 is partially embedded in the relief hole 32 so that when the password is unlocked, the center rod 61 abuts against the groove wall of the relief groove along the unlocking direction; and when the key is unlocked, the center rod 61 moves relative to the relief groove.

[0051] Specifically, the lock housing 1 has a support base 8 inside, and the lock hook 2 is movably installed at the support base 8. The lock tongue plate 3 is installed at the bottom of the support base 8.

[0052] Specifically, the support base 8 is integrally injection molded with multiple spring arms 81, which correspond one-to-one with multiple combination wheels 62. The outer side of the combination wheel 62 is circumferentially separated with stepping rotation grooves 621. The spring arms 81 are provided with damping protrusions 82 embedded in the stepping rotation grooves 621, so that the user has a good tactile feel when rotating the combination wheel 62. The base of the support hook 2 also has the function of the previous spring, and the structure is simpler.

[0053] Specifically, the lock housing 1 includes a base plate 12 and an upper cover 13 that are interlocked and fixed together, and the support base 8 is interlocked and fixed to the upper cover 13.

[0054] Specifically, the lock hook 2 and the button 4 are respectively arranged at both ends of the lock case 1, and the password component 6 is arranged in the middle of the lock case 1.
