Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a bag lock with a reasonable layout. Background Technology

[0002] With the continuous development of society and the continuous progress of science, the use of combination locks has become increasingly widespread, and they are now widely used in the luggage industry.

[0003] For front cover locks of bags, Chinese patent document CN218029615U discloses a double-hook combination lock for the front cover of a bag with USB function. It includes a lock body, a locking assembly, and a latch, as well as a USB assembly mounted on the lock body. The lock body includes a push button, which is linked to the locking assembly. The locking assembly includes two or more locking groups, and the latch has a latch groove adapted to the locking groups. When the bag lock is locked, the two or more locking groups engage with the latch groove, thereby limiting and locking the front cover of the bag. The locking assembly is also limited and locked by the push button. When the bag lock is unlocked, the two or more locking groups disengage from the latch groove, thereby unlocking the front cover of the bag. The push button is unlocked, and moving the push button can unlock the two or more locking groups and the latch groove. Using two or more locking mechanisms to lock the bag can effectively prevent the bag from being pried open from both sides. It also has a charging function, making it highly practical.

[0004] For example, Chinese patent document CN222976610U discloses a double-button multi-layer luggage lock, including a front cover lock body and a main lock body. The front cover lock body includes a support shell, a secondary lock latch, and a linkage rod. The support shell is provided with a secondary lock hole; the top of the support shell is provided with a placement groove. The main lock body includes a lock shell, a locking assembly, and a main lock latch. A first transmission rod and a second transmission rod are slidably provided inside the lock shell. The lock shell is also provided with a first button and a second button. Pressing the first button externally can drive the first transmission rod in a perpendicular direction to cause the main lock latch to unlock; pressing the second button externally can drive the second transmission rod and the linkage rod in a perpendicular direction to cause the secondary lock latch to unlock. By controlling the main lock latch and the secondary lock latch with the first and second buttons, the user only needs a small amount of force to press and unlock, improving the user experience. Furthermore, the charging module and the main lock body are integrated into the placement groove, making the entire lock body more compact and aesthetically pleasing.

[0005] Existing technology for locks on the front cover of bags uses a combination module where the central rod passes through multiple digital wheels. Therefore, the push button or button is arranged separately from the combination module, and there is a certain distance between the two, which can further improve the operation. Utility Model Content

[0006] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a bag lock with a reasonable layout.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A bag lock with a reasonable layout is provided, including a lock case, a combination module, lock hooks, and a transmission rod. The long, narrow lock case has front locking holes at both ends. Movable lock hooks are provided inside the lock case corresponding to the two front locking holes to engage with the lock of the bag's front cover when inserted into the front locking holes. The transmission rod is slidably installed inside the lock case and is linked to the two sets of lock hooks. Its characteristic is:

[0009] The password module includes an unlocking plate, a code adjustment plate, multiple number wheels, and multiple inner sleeves. Each number wheel is arranged in a straight line along the length of the lock case, and its center line is arranged along the width of the lock case and parallel to each other. Multiple inner sleeves are corresponding to each other and coaxially embedded in the sides of multiple number wheels, and the inner sleeves and the corresponding number wheels are circumferentially locked and rotate together on the same axis.

[0010] The lock case is also equipped with a button that is installed in a longitudinally elastic sliding manner. The number wheel, inner sleeve, unlocking plate, dialing plate and button are arranged in sequence along the width of the lock case. The flat plate-shaped unlocking plate and dialing plate are arranged vertically.

[0011] The unlocking plate and the switching plate can slide along the length of the lock case; in the locked state, the inner sleeve abuts against the unlocking plate to limit its movement; the lock case is equipped with a spring that applies force to the unlocking plate to keep the unlocking plate sliding.

[0012] A baffle is slidably provided at the bottom of the button. In the locked state, the baffle faces upward to block the button and prevent it from being pressed.

[0013] The button has a lock core inside. When locked, the lock core is fixed to the button. When unlocking with a key, inserting the correct key into the lock core and turning it can drive the baffle to slide. When unlocking with a combination, after multiple numbers are rotated to the correct combination, the inner sleeve makes room for the unlocking plate to slide. The unlocking plate slides automatically under the drive of the spring, causing the baffle to slide.

[0014] The sliding of the baffle releases the restriction on the button. When the button is pressed by external force, the transmission rod slides vertically, causing the lock hook to switch to the unlocking position.

[0015] 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 slots, allowing the unlocking plate to slide.

[0016] Specifically, the code-switching plate has multiple receiving slots on the side facing the unlocking plate. When the digital wheel and inner sleeve are turned to the correct password state, external force can push the code-switching plate to slide, which can move the inner sleeve to the receiving slot and disengage it from the digital wheel. After the code-switching plate is reset, the inner sleeve resets and engages with the digital wheel.

[0017] The lock case is slidably equipped with a positioning pin, and the unlocking plate has a guide groove; the code-changing plate has an L-shaped directional groove, which includes a clearance section arranged along the sliding direction of the code-changing plate and a positioning section perpendicular to the sliding direction of the code-changing plate; the positioning pin passes through the guide groove and the directional groove. When the password is incorrect, the positioning pin is inserted into the positioning section, preventing the code-changing plate from sliding; when the password is correct, the unlocking plate drives the positioning pin to slide through the guide groove, so that it is embedded in the clearance section, releasing the constraint on the code-changing plate.

[0018] Specifically, the top of the baffle has a long strip-shaped first stop, and the bottom of the button has a long strip-shaped second stop. In the locked state, the first stop aligns with and abuts against the second stop, preventing the button from being pressed; in the unlocked state, the baffle slides to a position where the first stop is offset from the second stop.

[0019] Specifically, the lock case includes an inner shell and an outer shell, both of which are elongated strips. Two sets of lock hooks are located at the two ends of the outer shell, and a button is installed in the middle of the outer shell. The two ends of the transmission rod are connected to the button and the lock hook, respectively. The inner shell is embedded in the groove with the opening facing upward in the middle of the outer shell, and the password component is installed in the inner shell.

[0020] Specifically, the bottom of the unlocking plate is connected to a U-shaped transition block, and the baffle has a shift groove. The transition block crosses the code plate and embeds into the shift groove. When the inner shell is assembled to the outer shell, the transition block matches the shift groove. The inner shell has a spring that applies force to the baffle. In the locked state, the transition block abuts against the baffle to restrict its sliding. When unlocking with a combination, the transition block slides with the unlocking plate to make room for the baffle to slide. When unlocking with a key, the lock cylinder overcomes the spring force at the baffle and drives the baffle to slide. When unlocking with a key and unlocking with a combination, the sliding direction of the baffle is opposite.

[0021] The baffle is equipped with a spring arm, the spring arm has a locking protrusion, and the inner shell has a stop protrusion. When the key unlocks, during the sliding process of the baffle, the stop protrusion squeezes the locking protrusion, causing the spring arm to deform and the locking protrusion to pass over the stop protrusion and be locked, thereby keeping the baffle in the unlocked position and allowing the lock cylinder to independently reset and remove the key.

[0022] The top of the baffle is also provided with a wedge-shaped protrusion, and the bottom of the button is provided with a reset drive post. When the key is unlocked and the button is pressed down, the reset drive post abuts against the wedge-shaped protrusion, overcoming the limit between the locking protrusion and the stop protrusion and forcing the baffle to reset.

[0023] Specifically, the outer casing has an upward-facing assembly groove at both ends, and the lock hook is rotatably installed in the assembly groove. A swing block is provided in the assembly groove, and the middle part of the swing block is rotatably installed in the assembly groove. In the locked state, one end of the swing block abuts against the lock hook to restrict its rotation. When unlocking, the transmission rod abuts against the swing block to rotate and release the constraint on the lock hook. The top of the assembly groove is detachably provided with a cover.

[0024] Specifically, the inner shell includes a fixed base shell and side plates. The base shell is provided with multiple horizontally placed support shafts. Multiple digital wheels and multiple inner sleeves are rotatably fitted on the multiple support shafts. The inner shell is provided with multiple clutch protrusions arranged in a ring trajectory on the inner wall corresponding to the digital wheels. The end face of the digital wheels is provided with multiple clutch grooves arranged in a ring trajectory. The clutch protrusions are embedded in the clutch grooves.

[0025] Specifically, the button has shafts on both sides facing each other, and the transmission rod includes a first rod and a second rod. The ends of the first rod and the second rod are respectively provided with inclined grooves for the shafts to be inserted, so that when the button is pressed down, the first rod and the second rod slide in a vertical direction.

[0026] Specifically, the first rod and the second rod are in the shape of sheet, with the first rod vertically embedded between the button and the unlocking plate.

[0027] The beneficial effects of this utility model are:

[0028] This utility model presents a bag lock with a reasonable layout. Compared with the prior art, the number wheel, inner sleeve, unlocking plate, code adjustment plate and button are arranged in sequence along the width of the lock shell, resulting in a more compact structure. The button can be placed closer to the number wheel, making it easier for the user to press the button after entering the password, thus improving the user experience. Attached Figure Description

[0049] 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.

[0050] This embodiment presents a reasonably arranged bag lock, such as... Figures 1 to 11 As shown, the lock includes a lock housing 1, a combination module 2, lock hooks 4, and a transmission rod 3. The long lock housing 1 has front lock holes 122 on the front sides of both ends. Inside the lock housing 1, there are movable lock hooks 4 corresponding to the two front lock holes 122, which are used to lock the buckle 6 of the front cover of the bag that is inserted into the front lock hole 122. The transmission rod 3 is slidably installed inside the lock housing 1 and is linked with the two sets of lock hooks 4. When the transmission rod 3 slides, it can drive the lock hooks 4 to switch to the unlocked state and release the buckle 6.

[0051] The password module 2 includes an unlocking plate 21, a code switching plate 22, multiple number wheels 23, and multiple inner sleeves 24. Each number wheel 23 is arranged sequentially in a straight line along the length of the lock case 1, and its center line is arranged parallel to the width of the lock case 1. The multiple inner sleeves 24 are corresponding to each other and coaxially embedded in the sides of the multiple number wheels 23, and the inner sleeves 24 and the corresponding number wheels 23 are circumferentially engaged and rotate together.

[0052] The lock housing 1 also features a button 7 that is longitudinally and elastically slidably mounted. A spring (not shown) is located below the button 7 to keep it facing upwards and returning to its original position. The number wheel 23, inner sleeve 24, unlocking plate 21, dialing plate 22, and button 7 are arranged sequentially along the width of the lock housing 1. The flat, plate-shaped unlocking plate 21 and dialing plate 22 are vertically arranged, occupying a small volume. The button 7 is aligned with the central position of the number wheel 23.

[0053] The unlocking plate 21 and the switching plate 22 can slide along the length of the lock case 1; in the locked state, the inner sleeve 24 abuts against the unlocking plate 21, and the unlocking plate 21 cannot slide. The lock case 1 is provided with a spring that applies force to the unlocking plate 21 so that the unlocking plate 21 maintains a sliding tendency. When the inner sleeve 24 gives way to the movement space of the unlocking plate 21, the unlocking plate 21 slides automatically.

[0054] A baffle 8 is slidably provided at the bottom of button 7, and the sliding direction of baffle 8 is the same as the sliding direction of unlocking plate 21. In the locked state, baffle 8 faces upward to block button 7 and prevent it from being pressed.

[0055] Button 7 contains a locking core 9, which is fixed to button 7 when locked. When unlocking with a key, inserting the correct key into locking core 9 and rotating it causes the baffle 8 to slide; specifically, the baffle 8 is moved by a lever at the bottom of locking core 9. When the combination is incorrect, unlocking plate 21 is constrained by inner sleeve 24 and cannot move, but it maintains a tendency to slide in the unlocking direction under spring force. When unlocking with a combination, after multiple number wheels 23 rotate to the correct combination, inner sleeve 24 creates space for unlocking plate 21 to slide, and unlocking plate 21 automatically slides under spring drive, causing baffle 8 to slide.

[0056] After the baffle 8 slides, it releases the restriction on the button 7. The external force presses the button 7 and drives the transmission rod 3 to slide in the vertical direction, causing the lock hook 4 to switch to the unlocking posture.

[0057] Specifically, the outer sides of the multiple inner sleeves 24 are respectively provided with unlocking slots 241, and the unlocking plate 21 is provided with multiple unlocking protrusions 211 corresponding to each unlocking slot 241. When the number wheel 23 turns to the correct password, all the unlocking protrusions 211 are aligned and embedded into the corresponding unlocking slots 241, thus making room for the unlocking plate 21 to slide.

[0058] Specifically, the code-changing plate 22 has multiple receiving slots 221 on its side facing the unlocking plate 21. When the digital wheel 23 and the inner sleeve 24 are rotated to the correct password state, an external force pushes the code-changing plate 22 to slide, which can move the inner sleeve 24 to the receiving slot 221 and disengage it from the digital wheel 23. At this time, the inner sleeve 24 does not rotate with the digital wheel 23. After rotating the digital wheel 23 to the new password, the code-changing plate 22 is reset, and the inner sleeve 24 is reset to cooperate with the digital wheel 23 to realize the code change.

[0059] The lock housing 1 is slidably provided with a positioning pin 10, and the unlocking plate 21 has a guide groove 212; the code-changing plate 22 has an L-shaped directional groove 222, which includes a clearance section 223 arranged along the sliding direction of the code-changing plate 22 and a positioning section 224 perpendicular to the sliding direction of the code-changing plate 22; the positioning pin 10 passes through the guide groove 212 and the directional groove 222. In the case of an incorrect password, the positioning pin 10 is inserted into the positioning section 224, preventing the code-changing plate 22 from sliding and avoiding code changes when the password is incorrect. When the password is correct, the unlocking plate 21 drives the positioning pin 10 to slide via the guide groove 212, causing it to engage with the clearance section 223, thus releasing the constraint on the code-changing plate 22.

[0060] Specifically, the top of the baffle 8 is provided with a long strip-shaped first stop bar 81, and the bottom of the button 7 is provided with a long strip-shaped second stop bar 71. In the locked state, the first stop bar 81 is aligned with and abuts against the second stop bar 71, thus preventing the button 7 from being pressed; in the unlocked state, the baffle 8 slides to a position where the first stop bar 81 is offset from the second stop bar 71.

[0061] Specifically, the lock case 1 includes an inner shell 11 and an outer shell 12, both of which are elongated strips. Two sets of lock hooks 4 are located at the two ends of the outer shell 12, and a button 7 is installed in the middle of the outer shell 12. The two ends of the transmission rod 3 are connected to the button 7 and the lock hooks 4, respectively. The inner shell 11 is embedded in the groove with the opening facing upward in the middle of the outer shell 12, and the password component is installed in the inner shell 11.

[0062] Specifically, the bottom of the unlocking plate 21 is connected to a U-shaped transition block 25, and the baffle 8 has a long strip-shaped shift groove 82. The transition block 25 spans the code plate 22 and embeds into the shift groove 82. When the inner shell 11 is assembled to the outer shell 12, the transition block 25 corresponds to and matches the shift groove 82. The inner shell 11 has a spring that applies force to the baffle 8. When unlocking with a combination, the spring unfolds and automatically drives the baffle to slide and unlock. When unlocking with a key, the lock core 9 overcomes the force of the spring and unlocks. In the locked state, the transition block 25 abuts against the baffle 8 to restrict its sliding. When unlocking with a combination, the transition block 25 slides with the unlocking plate 21 to make room for the baffle 8 to slide. When unlocking with a key, the lock core 9 overcomes the elasticity at the baffle 8 and drives the baffle 8 to slide. As can be seen from the above, when unlocking with a key and unlocking with a combination, the sliding direction of the baffle 8 is opposite. The principle is to make the first stop bar 81 offset from the second stop bar 71.

[0063] The baffle 8 is provided with a spring arm 83, and the spring arm is provided with a locking protrusion 831. The inner shell 11 is provided with a stop protrusion 115. When the key is unlocked, during the sliding process of the baffle 8, the stop protrusion 115 squeezes the locking protrusion 831, causing the spring arm 83 to bend and deform, so that the locking protrusion 831 passes over the stop protrusion 115 and reaches the other side to be locked, thereby keeping the baffle 8 in the unlocked position and allowing the lock core 9 to be independently reset and the key to be removed.

[0064] The top of the baffle 8 is also provided with a wedge-shaped protrusion 84, and the bottom of the button 7 is provided with a reset drive post. In this embodiment, the second stop bar 71 also serves as a reset drive post. When the key is unlocked and the button 7 is pressed down, the reset drive post abuts against the inclined surface of the wedge-shaped protrusion 84, overcomes the limitation between the locking protrusion 831 and the stop protrusion 115, and forces the baffle 9 to reset in the perpendicular direction.

[0065] Specifically, the outer casing 12 has an upward-facing assembly groove 121 at both ends. The locking hook 4 is rotatably installed in the assembly groove 121. The assembly groove 121 has a swing block 5. The middle part of the swing block 5 is rotatably installed in the assembly groove 121. In the locked state, one end of the swing block 5 abuts against the locking hook 4 to restrict its rotation. When unlocking, the transmission rod 3 abuts against the swing block 5 to rotate and release the constraint on the locking hook 4. The top of the assembly groove 121 is detachably provided with a cover 13.

[0066] Specifically, the inner shell 11 includes a fixed base shell 111 and a side plate 114. The base shell 111 is provided with multiple horizontally placed support shafts 112. Multiple digital wheels 23 and multiple inner sleeves 24 are rotatably fitted around the multiple support shafts 112. The inner shell 11 is provided with multiple clutch protrusions 113 arranged in a ring track on the inner wall corresponding to the digital wheels 23. The end face of the digital wheels 23 is provided with multiple clutch grooves 231 arranged in a ring track. The clutch protrusions 113 are embedded in the clutch grooves 231.

[0067] Specifically, the button 7 has shafts on both sides facing each other, and the transmission rod 3 includes a first rod 31 and a second rod 32. The ends of the first rod 31 and the second rod 32 are respectively provided with inclined grooves for the shafts to be inserted, so that when the button 7 is pressed down, the first rod 31 and the second rod 32 will slide in the vertical direction.

[0068] Specifically, the first rod 31 and the second rod are in the shape of a sheet, with the first rod 31 vertically embedded between the button 7 and the unlocking plate 21.

The bag lock with a reasonable layout according to claim 1, characterized in that: The outer sides of the multiple inner sleeves (24) are respectively provided with unlocking slots (241), and the unlocking plate (21) is provided with multiple unlocking protrusions (211) corresponding to each unlocking slot (241). When the number wheel (23) turns to the correct password, all the unlocking protrusions (211) are aligned and embedded into the corresponding unlocking slots (241), allowing the unlocking plate (21) to slide.

3. The bag lock with a reasonable layout according to claim 1, characterized in that: The code-switching plate (22) has multiple receiving slots (221) on its side facing the unlocking plate (21). When the digital wheel (23) and the inner sleeve (24) are turned to the correct password state, the external force moves the code-switching plate (22) to slide, which can move the inner sleeve (24) to the receiving slot (221) and disengage it from the digital wheel (23). After the code-switching plate (22) is reset, the inner sleeve (24) is reset and engages with the digital wheel (23). The lock case (1) is slidably provided with a positioning pin (10), and the unlocking plate (21) has a guide groove (212); the code plate (22) has an L-shaped directional groove (222), which includes a clearance section (223) arranged along the sliding direction of the code plate (22) and a positioning section (224) perpendicular to the sliding direction of the code plate (22); the positioning pin (10) passes through the guide groove (212) and the directional groove (222). In the case of incorrect password, the positioning pin (10) is inserted into the positioning section (224) to prevent the code plate (22) from sliding; when the password is correct, the unlocking plate (21) drives the positioning pin (10) to slide through the guide groove (212) so that it is embedded in the clearance section (223) and releases the constraint on the code plate (22).

4. The bag lock with a reasonable layout according to claim 1, characterized in that: The top of the baffle (8) is provided with a long strip first baffle (81), and the bottom of the button (7) is provided with a long strip second baffle (71). In the locked state, the first baffle (81) is aligned with and abuts against the second baffle (71) to prevent the button (7) from being pressed. In the unlocked state, the baffle (8) slides to the position where the first baffle (81) is offset from the second baffle (71).

5. A bag lock with a reasonable layout according to claim 1, characterized in that: The lock case (1) includes an inner shell (11) and an outer shell (12), both of which are long strips. Two sets of lock hooks (4) are located at the two ends of the outer shell (12). A button (7) is installed in the middle of the outer shell (12). The two ends of the transmission rod (3) are connected to the button (7) and the lock hook (4) respectively. The inner shell (11) is embedded in the groove with the opening facing upward in the middle of the outer shell (12). The password component is installed in the inner shell (11).

6. A bag lock with a reasonable layout according to claim 5, characterized in that: The bottom of the unlocking plate (21) is connected to a U-shaped transition block (25). The baffle (8) is provided with a shift groove (82). The transition block (25) crosses the code plate (22) and is embedded in the shift groove (82). When the inner shell (11) is assembled to the outer shell (12), the transition block (25) matches the shift groove (82). The inner shell (11) is provided with a spring that applies force to the baffle (8). In the locked state, the transition block (25) abuts against the baffle (8) to restrict its sliding. When unlocking with a password, the transition block (25) slides with the unlocking plate (21) to make room for the sliding of the baffle (8). When unlocking with a key, the lock core (9) overcomes the elastic force at the baffle (8) and drives the baffle (8) to slide. When unlocking with a key and unlocking with a password, the sliding direction of the baffle (8) is opposite. The baffle (8) is provided with a spring arm (83), the spring arm (83) is provided with a locking protrusion (831), and the inner shell (11) is provided with a stop protrusion (115). When the key unlocks, during the sliding process of the baffle (8), the stop protrusion (115) squeezes the locking protrusion (831) to deform the spring arm (83), so that the locking protrusion (831) passes over the stop protrusion (115) and is locked, thereby keeping the baffle (8) in the unlocked position and allowing the lock core (9) to be independently reset and the key to be removed. The top of the baffle (8) is also provided with a wedge-shaped protrusion (84), and the bottom of the button (7) is provided with a reset drive post. When the key is unlocked and the button (7) is pressed down, the reset drive post abuts against the wedge-shaped protrusion (84), overcoming the limit between the locking protrusion (831) and the stop protrusion (115) and forcing the baffle (8) to reset.

7. A bag lock with a reasonable layout according to claim 5, characterized in that: The outer casing (12) has an upward-facing assembly groove (121) at both ends. The lock hook (4) is rotatably installed in the assembly groove (121). The assembly groove (121) has a swing block (5). The middle part of the swing block (5) is rotatably installed in the assembly groove (121). In the locked state, one end of the swing block (5) abuts against the lock hook (4) to restrict its rotation. When unlocking, the transmission rod (3) abuts against the swing block (5) to rotate and release the constraint on the lock hook (4). The top of the assembly groove (121) is detachably provided with a cover (13).

8. A bag lock with a reasonable layout according to claim 5, characterized in that: The inner shell (11) includes a fixed base shell (111) and a side plate (114). The base shell (111) is provided with multiple horizontally placed support shafts (112). Multiple digital wheels (23) and multiple inner sleeves (24) are rotatably fitted around the multiple support shafts (112). The inner shell (11) is provided with multiple clutch protrusions (113) arranged in a ring track on the inner wall corresponding to the digital wheels (23). The end face of the digital wheels (23) is provided with multiple clutch grooves (231) arranged in a ring track. The clutch protrusions (113) are embedded in the clutch grooves (231).
