Description
Technical Field
[0001] This invention relates to the field of lock technology, and more specifically to a bag lock that is easy to operate. 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] In existing technology, bag locks include a locking assembly, which includes a locking hook and a locking buckle respectively installed on the two opening sides of the bag, which interlock and lock together. Alternatively, the locking assembly can lock the zipper pull. Bag locks also include an operating component (which can be replaced by a push, button, knob, etc.), a locking mechanism, and a transmission component. The locking mechanism can be a combination lock, key lock cylinder, or NFC, etc. The operating component is released only after the locking mechanism is unlocked with a combination, or after the correct key is inserted and turned, or after near-field electronic sensing is triggered. The operating component then drives the locking hook to rotate or slide via the transmission component, thereby releasing the locking from the locking buckle or releasing the restriction on the zipper pull, thus unlocking the bag.
[0004] Existing luggage locks all have operating mechanisms, whether push-operated, button-operated, or rotary, which occupy a certain amount of space in the lock body and require a corresponding internal transmission mechanism to achieve unlocking. With the development of the times, consumers are increasingly pursuing product simplicity and a fresh look, and traditional locks cannot meet this demand. Summary of the Invention
[0005] In view of the above-mentioned technical problems, the present invention provides a bag lock that is easy to operate.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A bag lock that is easy to operate is provided, including a lock body and a handle. The lock body includes a lock shell with a lock hole. A lock hook is movably provided inside the lock shell, aligned with the lock hole. A spring is also provided inside the lock shell to reset the lock hook after it has been displaced.
[0008] The lock case also features a locking mechanism that limits the locking hook to achieve locking. Unlocking is achieved only when the correct command is input into the locking mechanism; its characteristics are:
[0009] The handle is hinged to the lock housing at both ends. In normal operation, the handle is horizontally positioned and biased towards one side of the lock housing. When the handle is swung to the vertical lifting position by external force, the lock hook cannot be moved. In the unlocked position, when the handle is swung to the other side of the lock housing by external force, the lock hook can be moved from the locked position to the unlocked position.
[0010] Specifically, the lock hook is slidably installed inside the lock case, and the lock hook can be slid when the handle is turned to a preset angle.
[0011] Specifically, a linkage block is slidably provided inside the lock case. The linkage block and the lock hook are engaged by an inclined plane, so that the sliding direction of the linkage block is perpendicular to the sliding direction of the lock hook. When the handle is turned to a preset angle, the linkage block is slid, which in turn drives the lock hook to slide in a vertical direction.
[0012] Specifically, the handle head is provided with a toggle protrusion, and the linkage block is provided with a through receiving groove and a toggle groove. The toggle protrusion is movably received in the receiving groove. Only after the handle is turned to a preset angle, the toggle protrusion is embedded in the toggle groove and drives the linkage block to move.
[0013] Specifically, the lock hook includes a rod and a hook body. The rod is slidably installed inside the lock housing. The end of the rod engages with a linkage block. The hook body is located in the middle of the rod and is aligned with the lock hole.
[0014] Specifically, the locking mechanism includes a stop button, which is rotatably installed inside the lock housing. A stop block is provided on the outside of the stop button. In the locked state, the stop block aligns with and abuts against the lock hook to restrict its sliding; in the unlocked state, the stop block is displaced from the lock hook to release its restriction.
[0015] Specifically, the outer side of the stop button is also provided with a first drive unit. The locking mechanism includes a key assembly, which includes a lock core and an unlocking block. The unlocking block is installed at the bottom of the lock core. After the lock core is inserted with the correct key and turned, it drives the unlocking block to move the first drive unit, thereby driving the stop button to rotate and unlock.
[0016] Specifically, a second drive unit is provided on the outside of the stop button, and the locking mechanism also includes a password component. The password component includes a support, multiple password wheels and multiple adjustment wheels. The multiple password wheels are rotatably mounted on the lock housing, and the multiple adjustment wheels are installed one-to-one on the bottom of the multiple password wheels, and the adjustment wheels rotate together with the corresponding password wheels.
[0017] The support is slidably positioned below the code wheel. The support has multiple clearance protrusions located beside the multiple code wheels. Each code wheel has a clearance groove on its outer side. When each code wheel rotates to the correct code, each clearance protrusion aligns and embeds into the clearance groove of the corresponding code wheel, thereby causing the support to move the second drive unit, which in turn drives the stop button to rotate and unlock.
[0018] Specifically, a code-changing seat is slidably provided below the support, and a code-changing groove is provided on the top of the code-changing seat. When an external force pushes the code-changing seat until the code-changing groove aligns with the code-changing wheel, the code-changing wheel can detach from the code wheel and fall into the code-changing groove. After the code-changing seat is reset, the code-changing wheel resumes its engagement with the code wheel.
[0019] Specifically, the support is equipped with a limit seat. When the password is incorrect, the limit seat stops the code-changing seat from moving; when the password is correct, the limit seat releases the restriction of the code-changing seat.
[0020] The beneficial effects of this invention are:
[0021] This invention provides an easy-to-operate bag lock. In the unlocked state, external force can move the handle to the opposite side of the lock housing, causing the lock hook to move from the locked position to the unlocked position. This eliminates the need for additional operating mechanisms such as push or turn knobs, resulting in a simple and novel lock body. Furthermore, users typically grip the handle with their entire hand when unlocking, increasing the contact area and making unlocking more convenient. Simultaneously, the lock hook is only activated when the handle is turned beyond a certain angle, and rotating it from a horizontal to an vertical position retains the handle's original lifting function, making it multi-functional and increasing the bag lock's flexibility.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0043] This embodiment provides an easy-to-operate bag lock, such as... Figures 1 to 9 As shown, the lock includes a lock body 1 and a handle 2. The lock body 1 includes a lock shell 3. The lock shell 3 has two lock holes 31. A lock hook 4 is movably provided inside the lock shell 3, aligned with the position of the lock holes 31. The lock shell 3 also has a spring that causes the lock hook 4 to return to its original position after displacement. That is, the lock hook 4 tends to maintain the upward locking position. Only when the external force overcomes the spring force can the lock hook 4 be driven to slide.
[0044] In this embodiment, the lock housing 3 is also provided with a locking mechanism 5. The locking mechanism 5 limits the locking hook 4 to achieve locking. The locking hook 4 can only be released and unlocked by inputting the correct command into the locking mechanism 5. The locking mechanism 5 will be described in detail later.
[0045] The handle 2 is roughly C-shaped, with both ends hinged to the lock housing 3. Normally, the handle 2 is horizontally positioned, biased towards one side of the lock housing 3. External force can swing the handle 2 to a vertical, pulled position without moving the hook 4. In the unlocked state, where the locking mechanism 5 releases the restriction on the hook 4, and external force can move the handle 2 to the other side of the lock housing 3, moving the hook 4 from the locked position to the unlocked position. Generally, when the handle 2 is pulled to a vertical position, rotating it approximately 90° from horizontal to the pulled position, it fails to move the hook 4. In the locked state, the hook 4 cannot be moved either, but it does not interfere with the rotation of the handle 2, allowing it to retain its basic pulling function. Interference with the hook 4 only occurs when the handle 2 rotates more than 90°, approximately between 100° and 180°. Only after the locking mechanism 5 unlocks and releases the restriction on the hook 4 can the handle 2 move the hook 4.
[0046] Specifically, the lock hook 4 includes a rod 41 and a hook 42. The rod 41 is slidably installed inside the lock housing 3, and the hook 42 is located in the middle of the rod 41 and aligned with the lock hole 31 for hooking the zipper pull. Specifically, a linkage block 9 is slidably provided inside the lock housing 3. The linkage block 9 and the rod 41 of the lock hook 4 are engaged via an inclined surface, such that the sliding direction of the linkage block 9 is perpendicular to the sliding direction of the lock hook 4. When the handle 2 is turned to a preset angle, it drives the linkage block 9 to slide, thereby driving the lock hook 4 to slide in a vertical direction. In this embodiment, the hook 42 is integrally formed into the rod 41. Of course, in practice, the shape of the lock hook 4 can be changed to other forms, as long as the rotation of the handle 2 can drive it to move and unlock. A seat is also provided between the end of the rod and the linkage block 9 in the figure. Since this seat moves together with the rod, it can be understood as part of the rod.
[0047] Specifically, the head of the handle 2 is provided with a toggle protrusion 21, and the linkage block 9 is provided with a through receiving groove 91 and a toggle groove 92. The toggle protrusion 21 is movably received in the receiving groove 91. Only after the handle 2 is turned to a preset angle, the toggle protrusion 21 is embedded in the toggle groove 92, thereby driving the linkage block 9 to move.
[0048] In this embodiment, the locking mechanism 5 includes a stop button 6, which is rotatably mounted inside the lock housing 3. A stop block 61 is provided on the outer side of the stop button 6. In the locked state, the stop block 61 aligns with and abuts against the lock hook 4 to restrict its sliding; in the unlocked state, the stop block 61 is displaced from the lock hook 4 to release its restriction. A torsion spring is provided at the stop button 6 to keep the stop button 6 in a tendency to limit the lock hook 4.
[0049] Specifically, the outer side of the stop button 6 is also provided with a first drive part 62. The locking mechanism 5 includes a key assembly 7, which includes a lock core 71 and an unlocking block 72. The unlocking block 72 is installed at the bottom of the lock core 71. After the lock core 71 is inserted with the correct key and rotated, it drives the unlocking block 72 to move the first drive part 62, thereby driving the stop button 6 to rotate and unlock.
[0050] Specifically, the stop button 6 is further provided with a second drive unit 63 on its outer side. The locking mechanism 5 also includes a combination lock assembly 8, which includes a support 81, multiple combination wheels 82, and multiple dialing wheels 83. The multiple combination wheels 82 are rotatably mounted on the lock housing 3, and the multiple dialing wheels 83 are correspondingly mounted on the bottom of the multiple combination wheels 82, and the dialing wheels 83 rotate together with their corresponding combination wheels 82. The support 81 is slidably disposed below the dialing wheels 83. The support 81 is provided with multiple clearance protrusions 811 located beside the multiple dialing wheels 83. Each dialing wheel 83 has a clearance groove 831 on its outer side. When each combination wheel 82 rotates to the correct combination, each clearance protrusion 811 aligns and embeds into the clearance groove 831 of the corresponding dialing wheel 83, thereby causing the support 81 to move the second drive unit 63, which in turn drives the stop button 6 to rotate and unlock.
[0051] Specifically, a code-changing seat 84 is slidably provided below the support 81, and a code-changing groove 841 is provided on the top of the code-changing seat 84. When an external force pushes the code-changing seat 84 until the code-changing groove 841 aligns with the code-changing wheel 83, the code-changing wheel 83 can disengage from the code wheel 82 and fall into the code-changing groove 841. At this time, the code wheel 82 can be rotated to change to other codes. After the code-changing seat 84 is reset, the code-changing wheel 83 resumes to cooperate with the code wheel 82, thus completing the code adjustment.
[0052] Specifically, a limit seat 85 is provided at the support 81. In the case of an incorrect password, the limit seat 85 abuts against and aligns to prevent the code-changing seat 84 from moving, thus avoiding password changes when the password is incorrect. In the case of a correct password, the limit seat 85 disengages and releases the restriction on the code-changing seat 84.
