Description

Technical Field

[0001] This utility model relates to the field of customs lock technology, and in particular to a latch-type customs lock. Background Technology

[0002] Customs locks are used to ensure that luggage can be opened and inspected by customs officers without damage during transportation, while preventing unauthorized personnel from opening them. There are two ways to open a customs lock: one is a password set by the user, and the other is a customs-specific key. In current technology, most customs locks use a design that locks the zipper pull, for example, by using a buckle or pin mechanism to lock the zipper pull of the bag. This type of customs lock is only suitable for bags that close with zippers. However, for bags without zippers (such as hard-shell suitcases), traditional customs locks cannot complete the locking function, making it very inconvenient for bags without zippers to pass through customs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lockable customs lock that can lock bags without zippers and can be unlocked by a custom password or a customs key.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a latch-type customs lock, including a lock body and a latch. The lock body includes a shell and a base plate. The base plate is provided with a combination lock assembly, a key lock assembly, a lock block and at least one button. The latch is engaged with the base plate and hooks the button. The combination lock assembly and the key lock assembly can each independently drive the lock block to move. When the lock block is opposite to the button, the button cannot be pressed and the customs lock is in a locked state. When the lock block is misaligned with the button, pressing the button will unlock the combination lock.

[0005] Furthermore, the lock block is integrally provided with an inclined sliding groove, a mounting groove, and at least one stop bar. The combination lock assembly moves within the inclined sliding groove, and the lock block moves up and down as the combination lock assembly moves left and right. The key lock assembly abuts against the edge of the mounting groove. The key lock assembly rotates, causing the lock block to move up and down. A second spring is fixed between the lock block and the outer shell. The second spring is used to reset the lock block after it moves with the key lock assembly. The stop bar is used to prevent the button from being pressed.

[0006] Furthermore, the combination lock assembly includes a movable plate, multiple combination wheels, and multiple adjustment wheels. The combination wheels and the adjustment wheels are coaxially connected in a one-to-one correspondence via a concave-convex structure. An integral mounting post is provided inside the housing, passing through the combination wheels and the adjustment wheels. A combination groove is provided on the housing, with the combination wheels located within the groove. The adjustment wheels have grooves. A first slider is integrally provided on the movable plate, sliding within a slanted groove. A first spring is installed between the first slider and the lock block. Multiple adjustment holes are integrally provided on the movable plate, the number of which is the same as the number of adjustment wheels. A protrusion is integrally provided on the edge of each adjustment hole. When the adjustment wheel rotates until the protrusion aligns with the groove, the protrusion engages with the groove under the elastic force of the first spring. The first slider slides towards the opening of the slanted groove, and the lock block moves upward. When the adjustment wheel rotates to displace the protrusion from the groove, the first slider slides towards the rear end of the slanted groove, and the lock block moves downward.

[0007] Furthermore, the key lock assembly includes a lock cylinder, with a mating platform integrally formed at the bottom of the lock cylinder. The mating platform abuts against the edge of the mounting groove. A second slider is integrally formed on the outer edge of the mating platform. An arc-shaped sliding groove is formed on the base plate. The second slider slides within the arc-shaped sliding groove. The rotation of the lock cylinder causes the second slider to slide within the arc-shaped sliding groove, causing the lock block to move. A lock cylinder hole is formed on the outer shell, and the upper end of the lock cylinder protrudes through the lock cylinder hole.

[0008] Furthermore, there are two buttons symmetrically arranged on both sides of the base plate, and two stop levers corresponding to the buttons one by one. A third spring is fixed between the button and the housing, and the third spring is used to reset the button after it is pressed.

[0009] Furthermore, the stop lever is integrally provided with a protrusion, and the button is integrally provided with a recess. When the stop lever and the button are aligned, the protrusion is engaged with the recess, and the button cannot be pressed.

[0010] Furthermore, the latch is integrally provided with at least one locking hook, and the base plate is provided with at least one locking hook groove, and the locking hook passes through the locking hook groove to hook the corresponding button.

[0011] Compared with existing technologies, the advantages of this utility model are that by hooking the button into the bottom plate with the latch, it eliminates the reliance on the zipper when the bag is closed, enabling the customs lock to achieve the locking function on zipperless bags; at the same time, the combination lock component and the key lock component can be unlocked independently, allowing users to unlock themselves to protect their privacy, while customs officers can quickly and non-destructively inspect the bag with a special key, avoiding damage to the bag and customs clearance delays caused by forced lock breaking, and improving the security and cross-border passage efficiency of zipperless bags.

Detailed Implementation

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figures 1-6As shown, a lock-type customs lock includes a lock body 1 and a lock 2. The lock body 1 and lock 2 are fixed to the two sides of the bag, with the lock body 1 and lock 2 positioned opposite each other. The lock body 1 includes a shell 11 and a base plate 12. The base plate 12 is provided with a combination lock assembly 3, a key lock assembly 4, a lock block 5, and two buttons 6. A third spring 7 is fixed between the buttons 6 and the shell 11. The lock 2 is integrally provided with two lock hooks 21. The base plate 12 has two lock hook grooves 121. The lock hooks 21 pass through the lock hook grooves 121 and hook onto the corresponding buttons 6. The lock block 5 is integrally provided with a slanted sliding groove 51, a mounting groove 52, and two stops 53. The combination lock assembly 3 moves within the slanted sliding groove 51. The inclined plane of 51 is higher on the left and lower on the right. The locking block 5 moves up and down as the combination lock assembly 3 moves left and right. The key lock assembly 4 abuts against the edge of the mounting groove 52. The rotation of the key lock assembly 4 drives the locking block 5 to move up and down. A second spring 54 is fixed between the locking block 5 and the outer shell 11. The second spring 54 is used to reset the locking block 5 after it moves with the key lock assembly 4. The stop bar 53 corresponds to the button 6. The stop bar 53 is used to prevent the button 6 from being pressed. The stop bar 53 is integrally provided with a protrusion 531, and the button 6 is integrally provided with a notch 61. When the stop bar 53 and the button 6 are aligned, the protrusion 531 is engaged with the notch 61, and the button 6 cannot be pressed. The combination lock assembly 3 and the key lock assembly 4 can be operated independently. When the locking block 5 moves and is aligned with the button 6, the button 6 cannot be pressed, and the customs lock is in a locked state. When the locking block 5 and the button 6 are misaligned, pressing the button 6 unlocks the customs lock. The combination lock assembly 3 includes a movable plate 31, multiple combination wheels 32, and multiple adjustment wheels 33. The combination wheels 32 and adjustment wheels 33 are coaxially connected in a one-to-one correspondence through a concave-convex structure. An integral mounting post 111 is provided inside the outer shell 11, passing through the combination wheels 32 and adjustment wheels 33. A combination groove 112 is provided on the outer shell 11, and the combination wheels 32 are located in the combination groove 112. A groove 331 is provided on the adjustment wheel 33. A first slider 311 is integrally provided on the movable plate 31. A slider 311 slides within the inclined slide groove 51. A first spring 34 is installed between the first slider 311 and the locking block 5. Multiple adjustment holes 312 are integrally provided on the movable plate 31. The number of adjustment holes 312 is the same as the number of adjustment wheels 33. A protrusion 313 is integrally provided on the edge of the adjustment hole 311. When the adjustment wheel 33 rotates until the protrusion 313 corresponds to the groove 331, the protrusion 313 is engaged in the groove 331 under the elastic force of the first spring 34. The first slider 311 slides to the left end of the inclined slide groove 51, and the locking block 5 moves upward. When the adjustment wheel 33 rotates and the protrusion 313 is misaligned with the groove 331, the first slider 311 slides to the right end of the inclined slide groove 51, and the locking block 5 moves downward.The key lock assembly 4 includes a lock cylinder 41. A mating platform 42 is integrally formed at the bottom of the lock cylinder 41, abutting against the edge of the mounting groove 52. A second slider 43 is integrally formed on the outer edge of the mating platform 42. An arc-shaped sliding groove 122 is formed on the base plate 12, and the second slider 43 slides within the arc-shaped sliding groove 122. Rotation of the lock cylinder 41 causes the second slider 43 to slide within the arc-shaped sliding groove 122, thus moving the lock block 5. A lock cylinder hole 113 is formed on the outer casing 11, and the upper end of the lock cylinder 41 extends through the lock cylinder hole 113.

[0015] Unlocking by key: Customs officers insert a special key into the lock cylinder 41 through the lock cylinder hole 113 and rotate the key counterclockwise. This causes the mating platform 42 at the bottom of the lock cylinder 41 to rotate synchronously. At this time, the edge of the mating platform 42 abuts against the side wall of the mounting groove 52, pushing the lock block 5 to move upward against the resistance of the second spring 54. The upward movement of the lock block 5 causes the stop bar 53 to disengage from the button 6 area. The protrusions 531 of the two stop bars 53 exit from the recess 61 of the button 6. The lock block 5 and the button 6 are misaligned, releasing the obstruction to the button 6. Pressing the button 6 unlocks the lock. After customs inspection, the key is rotated in the opposite direction. The lock cylinder 41 returns to its initial position. The second spring 54 pushes the lock block 5 downward to reset. The protrusions 531 of the stop bars 53 re-engage into the recess 61 of the button 6, and the customs lock returns to the locked state.

[0016] Unlocking via password: The user rotates the password wheel 32 to the preset correct password, causing the coaxially connected code wheel 33 to rotate. When the groove 331 of the code wheel 33 aligns with the protrusion 313 of the movable plate 31, the first spring 34 releases its elastic force, pushing the movable plate 31 to the left. The first slider 311 of the movable plate 31 slides upward and to the left along the inclined slide groove 51, driving the lock block 5 to move upward, causing the protrusion 531 of the stop bar 53 to disengage from the recess 61 of the button 6. At this time, the lock block 5 and the button 6 are misaligned, and the second spring is compressed 54. Pressing the buttons 6 on both sides simultaneously with both hands causes the buttons 6 to retract inward against the resistance of the third spring 7. The lock hook 21 disengages from the button 6, the lock buckle 2 separates from the lock body 1, and the bag is opened. After releasing the button 6, the third spring 7 pushes the button 6 out and resets it. Rotating the password wheel 32 causes the groove 331 of the code wheel 33 to misalign with the protrusion 313, the movable plate 31 moves to the right, and the lock block 5 moves downward under the force of the second spring 54. The stop bar 53 realigns with the button 6, completing the locking.
