Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a bag lock with a horizontally arranged wheel assembly. 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] Existing technologies typically place the push mechanism next to the combination wheel, and incorporate the lock core within the push mechanism. However, the overall compactness of the structure needs improvement. Summary of the Invention

[0004] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a bag lock with a horizontally arranged wheel set.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bag lock with a horizontally mounted wheel assembly is provided, including a lock housing, a combination module, a key module, a lock hook, and a transmission rod. The lock hook is movably installed inside the lock housing, and the transmission rod is slidably installed inside the lock housing and linked with the lock hook.

[0007] The password module includes an unlocking plate, multiple circular number wheels, and multiple circular inner sleeves. The multiple number wheels are horizontally and rotatably mounted on the lock housing, and the multiple inner sleeves are installed one-to-one on the bottom of the multiple number wheels, and they are circumferentially engaged with each other and rotate together.

[0008] One of the digital wheels has a button inside, and a stop is slidably located below the button. In the locked state, the stop prevents the button from moving. When unlocking, the stop is driven to release the constraint on the button. External force pressing the button can cause the transmission rod to slide and unlock the lock hook.

[0009] The unlocking plate is slidably arranged at the bottom of the inner sleeve; after multiple number wheels rotate to the correct password, the unlocking plate can slide and drive the stop to release the constraint on the button;

[0010] The key module includes a lock core located within another digital wheel. When the correct key is inserted into the lock core and the rotation is performed, it can cause a stop to release the button from its restraint.

[0011] Specifically, each of the inner sleeves has an unlocking slot on its outer side, and the unlocking plate has multiple unlocking protrusions that correspond to each unlocking slot. When the number wheel is turned to the correct password, all the unlocking protrusions align and embed into the corresponding unlocking slot.

[0012] Specifically, the password module also includes a code adjustment plate that is slidably arranged at the bottom of the unlocking plate. The top of the code adjustment plate is provided with multiple receiving slots. When the number wheel and the inner sleeve are turned to the correct password state, external force can push the code adjustment plate to slide, which can cause the inner sleeve to fall into the receiving slot and disengage from the number wheel. After the code adjustment plate is reset, the inner sleeve is reset and cooperates with the number wheel.

[0013] A retaining element that can slide longitudinally elastically is provided at the stop component. When the password is incorrect, the retaining element abuts against and obstructs the sliding of the code-changing plate; when the password is correct, the stop component moves the retaining element downward via the inclined surface to release the restriction on the code-changing plate.

[0014] Specifically, the lock case has multiple mounting cylinders, multiple number wheels and multiple inner sleeves rotatably fitted onto the multiple mounting cylinders, and the lock core and button are assembled inside different mounting cylinders.

[0015] Specifically, the button includes a fixed pressing head and a linkage block. The pressing head is partially exposed outside the lock housing. The linkage block is provided with a pin, and the transmission rod is provided with an inclined groove. The pin passes through the inclined groove so that when the button is pressed, it drives the transmission rod to slide in the vertical direction.

[0016] Specifically, the linkage block is provided with a blocking part, and the stop member is provided with a stop protrusion. In the locked state, the stop protrusion aligns with and abuts against the blocking part, and the limit button is pressed; in the unlocked state, the stop member slides to the position where the stop protrusion is offset from the blocking part.

[0017] Specifically, the top of the stop part is provided with a dial part, and the unlocking plate extends with a drive protrusion. When the password is used to unlock, the drive protrusion abuts against the dial part.

[0018] Specifically, the key assembly includes a connecting block fixed to the bottom of the lock cylinder, with a connecting protrusion at the bottom of the connecting block; a stop member has a clearance groove, and the connecting protrusion is embedded in the clearance groove. When the key unlocks, the connecting protrusion abuts against the groove wall of the clearance groove, driving the stop member to slide; when the lock cylinder is locked, there is a distance between the connecting protrusion and the inner wall of the clearance groove so that the stop member can slide when unlocking with a combination.

[0019] Specifically, the lock case includes an inner shell and an outer shell, both of which are elongated strips. The bottom and sides of the outer shell are enclosed while the top is open. The inner shell is inserted into the outer shell through the open. The combination key and the stop are installed in the inner shell. Two sets of lock hooks are located at the two ends of the outer shell respectively. The transmission rod is located on the bottom outside of the inner shell, and the bottom of the inner shell has a hole for the button to pass through and engage with the transmission rod.

[0020] Specifically, the inner shell is installed in the middle of the outer shell, and assembly boxes are provided at both ends of the outer shell, with locking hooks installed inside the assembly boxes.

[0021] The beneficial effects of this utility model are:

[0022] This utility model discloses a bag lock with a horizontally arranged wheel assembly. Compared with the prior art, the button and lock core are arranged inside the digital wheel, resulting in a compact structure. Attached Figure Description

[0040] 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.

[0041] This embodiment describes a bag lock with horizontally positioned wheels, such as... Figures 1 to 8 As shown, it includes a lock housing 1, a combination module 2, a key module 3, a lock hook 4, and a transmission rod 5. The lock hook 4 is movably installed inside the lock housing 1 and engages with an external latch. The transmission rod 5 is slidably installed inside the lock housing 1 and is linked with the lock hook 4. Sliding the transmission rod 5 can drive the lock hook 4 to switch to the unlocked state. This is existing technology and will not be described in detail.

[0042] The password module 2 includes an unlocking plate 21, multiple annular number wheels 22, and multiple annular inner sleeves 23. The number wheels 22 are horizontally and rotatably mounted on the lock housing 1. The inner sleeves 23 are correspondingly mounted on the bottom of the number wheels 22 and are circumferentially engaged with each other for rotation. One of the number wheels 22 has a button 6 inside. A stop 7 is slidably located below the button 6. In the locked state, the stop 7 prevents the button 6 from moving and cannot be pressed. When unlocking, driving the stop 7 releases the constraint on the button 6. External force pressing the button 6 causes the transmission rod 5 to slide, thereby unlocking the lock hook 4. How the stop 7 is driven will be described in detail later.

[0043] The unlocking plate 21 is slidably arranged at the bottom of the inner sleeve 23. The outer sides of the multiple inner sleeves 23 are respectively provided with unlocking slots 231. The unlocking plate 21 is provided with multiple unlocking protrusions 211 corresponding to each unlocking slot 231. When the multiple number wheels 22 turn to the correct password, all the unlocking protrusions 211 are aligned and embedded into the corresponding unlocking slots 231, and the unlocking plate 21 can slide to drive the stop member 7 to release the constraint on the button 6.

[0044] Specifically, the password module 2 also includes a code-changing plate 24 slidably arranged at the bottom of the unlocking plate 21. The top of the code-changing plate 24 has multiple receiving slots 241. When the number wheel 22 and the inner sleeve 23 are in the correct password state, external force pushes the code-changing plate 24 to slide, allowing the inner sleeve 23 to align with the receiving slots 241. The inner sleeve 23 falls into the receiving slots 241 and disengages from the number wheel 22. At this time, rotating the number wheel 22 changes the password. After the code-changing plate 24 is reset, the inner sleeve 23 resets and engages with the number wheel 22. A retaining member 25 that can elastically slide longitudinally is provided at the stop member 7. In the case of an incorrect password, the retaining member 25 abuts against and obstructs the sliding of the code-changing plate 24, preventing password changes when the password is incorrect. In the case of a correct password, the stop member 7, via an inclined surface, moves the retaining member 25 downwards, releasing the restriction on the code-changing plate 24.

[0045] The key module 3 includes a lock core 31 located within another digital wheel 22. When the correct key is inserted into the lock core 31 and it is turned, it can cause the stop member 7 to release the constraint on the button 6.

[0046] In this embodiment, the lock housing 1 is provided with multiple assembly cylinders 11, multiple digital wheels 22 and multiple inner sleeves 23 are rotatably fitted on the multiple assembly cylinders 11, and the lock core 31 and the button 6 are assembled in different assembly cylinders 11.

[0047] Specifically, button 6 includes a fixed pressing head 61 and a linkage block 62. The pressing head 61 is partially exposed outside the lock housing 1. The linkage block 62 is provided with a pin 63. The transmission rod 5 is provided with a groove 51. The pin 63 passes through the groove 51 so that when button 6 is pressed, it drives the transmission rod 5 to slide in the vertical direction.

[0048] Specifically, the linkage block 62 is provided with a blocking part 64, and the stop member 7 is provided with a stop protrusion 71. In the locked state, the stop protrusion 71 aligns with and abuts against the blocking part 64, and the restriction button 6 is pressed. In the unlocked state, the stop member 7 slides to the position where the stop protrusion 71 is offset from the blocking part 64.

[0049] Specifically, the top of the stop member 7 is provided with a dialing part 72, and the unlocking plate 21 extends with a driving protrusion 212. When unlocking with a password, the driving protrusion 212 abuts against the dialing part 72. It can be seen that the stop member 7 moves in one direction, whether unlocking with a password or a key, it moves in the same direction.

[0050] Specifically, the key assembly includes a connecting block 32 fixed to the bottom of the lock core 31, and a connecting protrusion 33 is provided at the bottom of the connecting block 32; the stop member 7 has a clearance groove 73, and the connecting protrusion 33 is embedded in the clearance groove 73. When the key unlocks, the connecting protrusion 33 abuts against the groove wall of the clearance groove 73 and drives the stop member 7 to slide; when the lock core 31 is locked, there is a distance between the connecting protrusion 33 and the inner wall of the clearance groove 73 so that the stop member 7 can slide when unlocking with a password.

[0051] Specifically, the lock case 1 includes an inner shell 12 and an outer shell 13, both of which are elongated. The bottom and sides of the outer shell 13 are enclosed while the top is open. The inner shell 12 is inserted into the outer shell 13 through the open. The assembly cylinder 11 is integrally formed on the inner shell 12. The combination lock assembly and the stop member 7 are installed on the inner shell 12. Two sets of lock hooks 4 are located at the two ends of the outer shell 13 respectively. The transmission rod 5 is located on the bottom outside of the inner shell 12. The bottom of the inner shell 12 has a hole for the button 6 to pass through and cooperate with the transmission rod 5.

[0052] Specifically, the inner shell 12 is installed in the middle of the outer shell 13, and the two ends of the outer shell 13 are provided with assembly boxes 14. The locking hook 4 is installed in the assembly box 14, that is, the assembly box 14 and the locking hook 4 form a module, which is then fixed to the outer shell 13 as a whole.
