Description

Technical Field

[0001] This invention relates to the field of lock technology, and more specifically to a user-friendly bag lock. Background Technology

[0002] Bag locks on the market can be unlocked with keys or digital passwords. To further facilitate users in opening the locks, some bag locks have also added electronic unlocking functions.

[0003] See patent document CN2020209636738, which discloses a combination lock including a pin tumbler lock, an electronic lock, and a combination lock. Each lock is linked to the latch via a movable plate assembly. The user controls the locking or unlocking of each lock, thereby controlling the release or locking of the latch. When the latch is locked, all locks are in a locked state. To release the latch, the user can unlock any one of the pin tumbler lock, electronic lock, or combination lock. This lock can be unlocked using a key, digital password, or electrical signal control. However, regardless of the unlocking method, it requires pushing and shoving to unlock, which is laborious and inconvenient. Furthermore, when using an electronic module for unlocking, it cannot unlock automatically, resulting in a low level of automation. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient bag lock with three unlocking methods, which can solve the problem of cumbersome unlocking in the past.

[0005] The objective of this invention is achieved through the following technical solution: This application provides a convenient bag lock, including a lock housing, a latch rotatably installed within the lock housing, and a lock block for abutting against the latch to achieve locking. The lock block is rotatably installed within the lock housing. The lock housing also includes a movable component and a button that can move vertically and drive the movable component to slide along the length of the lock housing. The movable component abuts against the lock block so that the movable component can drive the lock block to rotate. The lock housing also includes a locking mechanism for limiting the sliding of the movable component. The locking mechanism includes a lock cylinder assembly for unlocking, a combination wheel assembly, and a motor assembly.

[0006] The movable component includes a movable part and a movable block. The movable part extends into a slot toward the movable block, and the movable block extends into a protrusion toward the slot. The protrusion is inserted into the slot.

[0007] The movable part has a trapezoidal groove, one end of the locking block extends into the trapezoidal groove to form a rotating part, and the other end of the locking block abuts against the latch. The lock housing has a return spring that drives the locking block to rotate in the upward locking direction. In the assembled state, the rotating part is inserted into the trapezoidal groove.

[0008] The movable block is located below the button, and the movable block extends a first wedge-shaped portion toward the button, while the button extends a second wedge-shaped portion toward the movable block that is complementary to the first wedge-shaped portion.

[0009] The combination wheel assembly is located on one side of the movable block. The combination wheel assembly includes a reciprocating axle, and a groove is provided at the end of the axle facing the movable block. A clutch block is provided in the groove and abuts against the movable block. The clutch block can slide in the groove along the width direction of the lock case. When the combination is incorrect, the axle abuts against the clutch block to restrict the movable block from sliding in the unlocking direction. When the combination is correct, the axle can extend and retract, releasing the restriction on the movable block sliding in the unlocking direction.

[0010] The lock cylinder assembly is located between the combination wheel assembly and the movable block. The lock cylinder assembly includes a rotatable lock cylinder body, with an actuating part extending from the lock cylinder body toward the clutch block. The clutch block has a guide groove for the actuating part to be inserted into, and the actuating part is inserted into the guide groove and can slide along the guide groove. When unlocking, the lock cylinder body rotates, causing the clutch block to slide along the width direction of the lock shell. The clutch block and the movable block are misaligned to release the restriction on the movable block sliding in the unlocking direction.

[0011] The motor assembly includes a motor body, which has a rotating shaft arranged along the width of the lock housing. A rotating disk is fixed to the rotating shaft, and a rotating arm extends from the rotating disk toward the movable block. A groove is provided on the side of the movable block facing the rotating arm for the rotating arm to be inserted. When locked, the rotating arm is placed in the groove to restrict the movable block from sliding in the unlocking direction. When unlocked, the motor body drives the rotating arm to rotate, and the rotating arm pushes the movable block to slide in the unlocking direction to achieve unlocking.

[0012] The motor assembly also includes a PCB board and a battery. The PCB board is electrically connected to the motor body, and the battery is placed inside the lock housing and electrically connected to the PCB board.

[0013] It also includes a lock hook, and the side of the lock case facing the lock hook has a lock hole for the lock hook to be inserted. After the lock hook is inserted into the lock hole, it is engaged with the lock buckle.

[0014] The bag lock of the present invention has the following beneficial effects:

[0015] (1) The overall structure is simple and compact, and the layout is reasonable. The luggage lock can be unlocked by three unlocking methods: key, password and electric control, making unlocking more convenient and faster, and improving the convenience of the luggage lock.

[0016] (2) The push button is used for unlocking, which is more labor-saving and easier to unlock than the traditional horizontal push unlocking method. It solves the problem of the previous unlocking trouble, saves the complex design of the lock cylinder component combined with the unlocking component, and is easier to manufacture and lower in cost.

[0017] (3) In other embodiments, when electric control is used for unlocking, there is no need to press a button. The motor assembly automatically unlocks the lock, which is more automated, more convenient to use, and improves the consumer experience. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0027] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] An embodiment of the present invention, a convenient bag lock, is as follows: Figures 1 to 2 As shown, the bag lock includes a lock housing, which comprises a cover plate and a faceplate 11. The cover plate and faceplate 11 are detachably connected, specifically by snap-fit ​​or screw thread connection. Two lock holes 13 are provided on the side of the faceplate 11. A latch 8, rotatably mounted in the cover plate, is located within each lock hole 13. A hook 2 is provided on the outside of each lock hole 13. The lock holes 13 are for inserting the hook 2, which engages with the latch 8 after insertion, thus locking the bag. Figure 3 Specifically, the lock hook 2 has a hook portion 21, and the latch 8 has an upper locking groove 81 at one end facing the lock hook 2. The other end of the latch 8 extends into an unlocking portion 82. The latch 8 is rotatably mounted in the lock case via a pivot. To facilitate opening, the latch 8 is also provided with a torsion spring that drives the latch 8 to rotate in the unlocking direction (taking the right latch 8 as an example, clockwise rotation is the unlocking direction). To achieve the anti-theft function, the lock case is provided with a lock block 9 for abutting against the unlocking portion 82 of the latch 8 to achieve locking.

[0030] In this embodiment, the locking block 9 is rotatably mounted inside the lock housing. Specifically, the locking block 9, like the latch 8, is rotatably mounted inside the lock housing via a pivot. The lock housing also includes a movable component and a button 3 that can move vertically and drives the movable component to slide along the length of the lock housing. The movable component abuts against the locking block 9 so that the movable component can drive the locking block 9 to rotate.

[0031] Combination Figure 4The movable component includes a movable part 71 and a movable block 72. The movable part 71 extends into a slot 711 toward the movable block 72, and the movable block 72 extends into a protrusion 721 toward the slot 711. The protrusion 721 is inserted into the slot 711. Thus, when the movable block 72 is pushed, the movable block 72 will simultaneously drive the movable part 71 to slide. Both sides of the movable part 71 are provided with trapezoidal grooves 712. One end of the locking block 9 extends a rotating part 91 towards the trapezoidal groove 712, and the other end of the locking block 9 extends a T-shaped block 92 that abuts against the unlocking part 82 of the latch 8. The lock housing is provided with a return spring 90 that drives the locking block 9 to rotate in the locking direction (taking the right locking block 9 as an example, counterclockwise). In the assembled state, the rotating part 91 is inserted into the trapezoidal groove 712. The trapezoidal groove 712 has two symmetrical inclined surfaces. When the movable part 71 slides to the left or to the right, the groove wall of the trapezoidal groove 712 will abut against the rotating part 91 of the locking block 9, thereby driving the locking block 9 to rotate around the pivot.

[0032] In the locked state, the return spring 90 provides pressure to the locking block 9, forcing the T-shaped block 92 of the locking block 9 to abut against the end of the latch 8, thereby restricting the rotation of the latch 8 and achieving locking. During unlocking, the movable member 71 is pushed, and with the cooperation of the trapezoidal groove 712 and the rotating part 91 of the locking block 9, the movable member 71 pushes the locking block 9 to rotate in the unlocking direction, thereby releasing the locking block 9 from abutting the latch 8 and achieving unlocking.

[0033] Combination Figure 3 and Figure 4 The movable block 72 is located below the button 3, which can slide vertically. The movable block 72 extends a first wedge-shaped portion 31 towards the button 3, and the button 3 extends a second wedge-shaped portion 722 towards the movable block 72, complementary to the first wedge-shaped portion 31. When unlocking, a downward pressure is applied to the button 3. As the button 3 slides vertically, the second wedge-shaped portion 722 abuts against the first wedge-shaped portion 31 of the movable block 72, thus converting the vertical sliding of the button 3 into sliding of the movable block 72 along the length of the lock case. This pressing unlocking method is more convenient and less strenuous than the traditional pushing unlocking method. It should be noted that, to facilitate the automatic return of the button 3 after pressing, a spring is provided between the button 3 and the inner bottom surface of the lock case to drive the button 3 to slide upwards.

[0034] In this embodiment of the luggage lock, when unlocking, button 3 pushes the movable block 72 and the movable component 71 to slide. The sliding of the movable component 71 drives the lock block 9 to rotate in the unlocking direction, thereby releasing the movement restriction of the lock block 9 on the latch 8. Therefore, to achieve locking and anti-theft, a locking mechanism is needed to restrict the sliding of the movable block 72. In this embodiment, the lock case also has a locking mechanism for restricting the sliding of the movable components. The locking mechanism includes a lock cylinder assembly 5 for unlocking, a combination wheel assembly 4, and a motor assembly 6.

[0035] Please seeFigure 5 The combination wheel assembly 4 and the lock cylinder assembly 5 are both located on the left side of the movable block 72, with the lock cylinder assembly 5 located between the movable block 72 and the combination wheel assembly 4, while the motor assembly 6 is installed on the right side of the movable block 72. The combination wheel assembly 4 and the lock cylinder assembly 5 are used to restrict the movable block 72 from sliding to the left, while the motor assembly 6 is used to restrict the movable block 72 from sliding to the right.

[0036] Combination Figure 6 The combination wheel assembly 4 includes a reciprocating axle 41, similar to a conventional combination wheel assembly 4. When the combination is correct, the axle 41 reciprocates; when the combination is incorrect, the axle 41 is locked and cannot reciprocate. A groove 43 is provided at the end of the axle 41 facing the movable block 72. A clutch block 42, which abuts against the movable block 72, is provided within the groove 43. The clutch block 42 can slide within the groove 43 along the width of the lock housing. The clutch block 42 is designed to prevent interference with the lock cylinder assembly 5 during unlocking. The clutch block 42 is L-shaped.

[0037] The process of unlocking or locking using a digital password is as follows: Figure 5 Taking the password as an example, when the password is incorrect, the axle 41 abuts against the clutch block 42, and the clutch block 42 abuts against the movable block 72, thus restricting the movable block 72 from sliding to the left. When the password is correct, the axle 41 can extend and retract, releasing the restriction on the movable block 72 sliding to the left. Finally, pressing button 3 will drive the movable block 72 and the movable part 71 to slide to the left to unlock the device.

[0038] Please see Figure 6 The lock cylinder assembly 5 includes a rotatable lock cylinder body 51. The lock cylinder body 51 extends a toggle part 52 toward the clutch block 42. The clutch block 42 has a guide groove 421 for the toggle part 52 to be inserted. The toggle part 52 is inserted into the guide groove 421 and can slide along the guide groove 421.

[0039] When inserting the key to unlock, see [link / reference]. Figure 5 and Figure 6 The lock cylinder body 51 rotates, causing the actuating part 52 to make a circular motion. Since the actuating part 52 is inserted into the guide groove 421 of the clutch block 42, the actuating part 52 will push the clutch block 42 to slide along the width direction of the lock shell during the process. The actuating part 52 slides in the guide groove 421, thereby causing the clutch block 42 to be misaligned with the movable block 72. Even if the combination wheel assembly 4 is in the locked state, it can still release the restriction on the movable block 72 to slide to the left. Finally, by pressing the button 3, the movable block 72 and the movable part 71 can be driven to slide to the left to unlock.

[0040] Combination Figure 5The motor assembly 6 includes a motor body 61. The motor body 61 is provided with a rotating shaft arranged along the width direction of the lock housing. A rotating disk 62 is fixedly connected to the rotating shaft. A rotating arm 63 extends from the rotating disk 62 toward the movable block 72. A groove 723 for the rotating arm 63 to be inserted is provided on the side of the movable block 72 facing the rotating arm 63.

[0041] When the motor assembly 6 is locked, the rotating arm 63 is placed in the groove 723 to restrict the movable block 72 from sliding to the right. When the motor assembly 6 is unlocked, the motor body 61 receives an external electrical signal and operates. The output shaft of the motor body 61 rotates, which drives the rotating arm 63 to rotate via the rotating disk 62. During the rotation of the rotating arm 63, it pushes the movable block 72 to slide to the right, thereby unlocking the motor assembly 6. After receiving the unlocking electrical signal, the motor body 61 automatically drags the movable block 72 to unlock the motor assembly 6, eliminating the need to press the button 3. This method is more convenient and faster than the traditional method that requires pushing or pressing the unlocking part 82.

[0042] Combination Figure 6 In this embodiment, the motor assembly 6 further includes a PCB board 64 and a battery 65. The PCB board 64 is electrically connected to the motor body 61, and the battery 65 is placed inside the lock housing and electrically connected to the PCB board 64. It should be noted that the PCB board 64 can integrate functional modules such as a remote module, a Bluetooth module, and a fingerprint recognition module, as long as it can provide electrical signals to the motor body 61.

[0043] The working process of the bag lock in this embodiment is as follows: In the locked state, such as Figure 5 Figure 3 Figure 5 As shown, the motor body 61 stops rotating, and the motor body 61 abuts against the movable block 72 through the rotating arm 63, thereby restricting the movable block 72 from sliding to the right. The wheel axle 41 is in a non-extending state. The lock cylinder body 51 drives the clutch block 42 to rotate to the locked position. The non-moving clutch block 42 abuts against the movable block 72, thereby restricting the movable block 72 from sliding to the left. Since the movement of the movable block 72 is restricted, the movable part 71 cannot slide either. Therefore, the movable part 71 cannot drive the lock block 9 to rotate. The lock block 9 always abuts against the latch 8, thereby achieving locking.

[0044] When unlocking, any one of the following methods can be used: combination wheel assembly 4, lock cylinder assembly 5, or motor assembly 6. Motor assembly 6 can be unlocked automatically after unlocking, while combination wheel assembly 4 and lock cylinder assembly 5 can be unlocked by pressing button 3.

[0045] The luggage lock in this embodiment features a simple and compact overall structure with a reasonable layout. It can be unlocked via key, combination, and electric control, making unlocking more convenient and faster, thus improving the lock's usability. The push-button unlocking method (3) requires less effort and is more convenient than the traditional horizontal push method, solving the previous cumbersome unlocking issues. It also eliminates the complex design of integrating the lock cylinder assembly (5) with the 82-piece unlocking unit, making manufacturing easier and lower in cost. When using electric control unlocking, there is no need to press button (3); the motor assembly (6) automatically unlocks the lock, resulting in a higher degree of automation, greater ease of use, and improved user experience.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
