Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a lock for bags and luggage. Background Technology

[0002] In the field of locks for products such as bags and cabinets, push-type unlocking structures are widely used due to their operational characteristics. For example, the combination lock structure for bags disclosed in patent number CN214740564U has certain shortcomings in terms of hook plate locking and push-block operation. Regarding hook plate locking, it requires the synchronous rotation of the combination wheel and inner wheel, the alignment of the inner wheel notch with the protrusion I on the push plate, and the contact between the locking member's support leg I and the hook plate to achieve locking. The combination wheel lock mechanism of this structure relies on the complex linkage of multiple components to lock the hook plate, which is prone to jamming or mis-locking due to component misalignment, affecting the stability of the lock. Regarding push-block operation, the pushing direction of the push block is in the same straight line as the sliding direction of the hook plate. When unlocking, the push block directly applies a pushing force along the sliding direction of the hook plate, requiring a large external force and making the operation relatively laborious. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a lock for bags and luggage, which uses a bolt to directly lock the lock plate, resulting in a simple locking structure; and the button unlocking operation is convenient and effortless.

[0004] The technical solution of this utility model is as follows: A bag lock includes a lock body that cooperates with a lock hook. The lock body has a shell and a lock plate, a combination wheel assembly, and a button disposed on the shell. The lock plate has a latch, and the lock plate can slide horizontally to lock or unlock the lock hook. The combination wheel assembly allows the lock plate to slide when the combination is correct and locks the lock plate when the combination is incorrect. The combination wheel assembly includes a rotatable inner wheel group and a combination wheel group, a slidable bolt, and a main reset member that can reset the bolt. The bolt and the lock plate slide synchronously in the horizontal direction. The button is exposed on the upper surface of the housing and slides vertically. The button and the bolt form an inclined surface fit. When the password is correct, press the button down. Through the engagement with the inclined surface of the bolt, the bolt is pushed to move the lock plate in the unlocking direction, so that the bolt tongue disengages from the lock hook. After releasing the button, the main reset component drives the bolt to move the lock plate in the locking direction to reset, so that the bolt tongue locks the lock hook.

[0005] Using the above technical solution, the bolt and the locking plate slide synchronously in the horizontal direction, forming a transmission link of "the bolt directly drives the locking plate". This eliminates the need for intermediate transmission components such as multi-stage levers or gears in traditional structures, reducing force transmission loss and avoiding action delays caused by deformation or gaps in intermediate components. At the same time, the button slides vertically and forms an inclined surface with the bolt. When pressed down, the vertical pressing force can be converted into the horizontal driving force of the bolt. The inclined surface characteristic enables force-saving transmission, making the operation more ergonomic. After releasing the button, the main reset component directly drives the bolt to reset the locking plate, ensuring that the bolt accurately locks back into the locking hook.

[0006] A further feature of this invention is that the outer shell is provided with a password reset key, and each password wheel and the corresponding inner wheel are axially sliding and circumferentially linked through a snap-fit ​​structure. The password reset key can push the inner wheel to slide relative to the password wheel.

[0007] With the above further settings, when the password needs to be reset, press the password reset button. The password reset button pushes the inner wheel to slide relative to the password wheel. At this time, the password wheel can be freely rotated to set a new password.

[0008] A further feature of this invention is as follows: the password reset key and button are distributed at both ends of the password wheel assembly. The password reset key is exposed on the upper surface of the outer shell and slides vertically. The password reset key and the inner wheel push seat at one end of the inner wheel assembly form an inclined surface engagement. The bolt is provided with an end seat. The main reset component is a spring, which is sleeved on the bolt and abuts against the other end of the inner wheel assembly and the end seat. When the password reset key is pressed down, it pushes the inner wheel push seat to slide through the inclined surface engagement with the inner wheel push seat, causing the locking structure to disengage and release the circumferential linkage between the password wheel and the inner wheel. When the password reset key is released, the main reset component drives the inner wheel assembly to slide back to its original position, causing the locking structure to engage and restore the circumferential linkage between the password wheel and the inner wheel.

[0009] By adopting the above-mentioned further configuration, the main reset component (spring) is integrated between the bolt and the inner wheel assembly, serving as both the power source for bolt reset and the function of resetting the inner wheel assembly (restore password linkage), thus achieving "one spring for two purposes"; at the same time, the password reset key and button are located at opposite ends to avoid mutual interference during operation.

[0010] When the password reset button is pressed, the inclined design of the button and the inner wheel push seat ensures that the inner wheel can slide smoothly and steadily, thereby allowing the locking structure to disengage smoothly, releasing the circumferential linkage between the password wheel and the inner wheel, and realizing the password reset function. When the user releases the password reset button, the elastic force of the main reset component will drive the inner wheel assembly to slide and reset quickly, the locking structure will re-engage, and the circumferential linkage between the password wheel and the inner wheel will be restored, ensuring the normal use of the lock.

[0011] A further feature of this invention is that a locking structure is provided between the password reset key and the inner wheel push seat. After the password reset key is pressed down, the locking structure enables the password reset key to be positioned and engaged with the inner wheel push seat, so as to maintain the pressed state of the password reset key.

[0012] By adopting the above-mentioned further settings, the password reset button is locked in a snap-fit ​​structure to ensure that the inner wheel group remains unlocked (without rebounding) during the password reset process. Users can adjust the password wheel at their leisure, which solves the problem of having to hold down the reset button during traditional resets and the risk of reset failure due to slippage, thus improving the stability of password modification.

[0013] A further feature of this invention is as follows: the password reset key has a first inclined surface and a first locking surface at its upper end, and the inner wheel push seat has a second inclined surface and a second locking surface at its lower end. The first inclined surface and the second inclined surface form an inclined surface fit, and the first locking surface and the second locking surface form a locking structure. The locking surface is an inclined surface. When the password reset key is pressed down, the first inclined surface contacts the second inclined surface, causing the inner wheel push seat to drive the inner wheel to slide until the first locking surface and the second locking surface abut against each other, thus positioning the pressed password reset key.

[0014] With the above-mentioned further settings, when the password reset key is pressed, the first inclined surface and the second inclined surface first form a sliding engagement. When the sliding reaches the preset position, the first locking surface moves below the second locking surface. The main reset component can cause the first locking surface and the second locking surface to form a top contact, completing the positioning and ensuring the stability of the structure. The inclined surfaces of the first and second locking surfaces facilitate separation to release the engagement. At this time, the password reset key can spring back to reset, and the main reset component drives the inner wheel assembly and the inner wheel push seat to slide horizontally to reset.

[0015] A further feature of this invention is that the outer shell includes a receiving chamber formed by the cooperation of a base and a top cover. The top cover is provided with a password cavity, the password wheel assembly is installed in the password cavity, a bottom cover is provided at the bottom of the password cavity, and the locking plate is slidably disposed below the bottom cover.

[0016] With the above-mentioned further configuration, the combination wheel assembly is independently placed in the combination cavity of the upper cover, and the locking plate is hidden under the bottom cover, forming a partitioned layout of "upper operating area + lower transmission area", which facilitates modular assembly of each component (such as replacing the combination wheel assembly separately).

[0017] A further feature of this invention is that the button can be vertically slidably mounted in the password cavity, and a button reset component is provided between the button and the bottom cover below, the button reset component being used to reset the button upwards.

[0018] With the above-mentioned further modifications, a button reset component is added between the button and the bottom cover to ensure that the button automatically springs back to its initial position after being pressed to unlock.

[0019] A further feature of this invention is that the outer circumference of the combination wheel is provided with multiple circumferential slots, and the bottom cover is provided with elastic paddles corresponding to the positions of each combination wheel. One end of the elastic paddle is integrally connected to the bottom cover, and the other end is elastically pressed against the outer circumference of the combination wheel. When the combination wheel is rotated, the end of the elastic paddle alternately engages or disengages from each slot.

[0020] With the above-mentioned further design, the gear slot on the outer periphery of the combination wheel cooperates with the elastic paddle on the bottom cover. When rotated, the paddle alternately engages and disengages from the slot, producing a clear "click" tactile and audible feedback. Users can perceive whether the combination is in place without visual inspection, solving the problem of easy errors in combination input during blind operation, and is especially suitable for low-light scenarios.

[0021] A further feature of this invention is that the locking plate includes a first locking plate and a second locking plate that are slidably disposed in the accommodating chamber, the two locking plates being linked together, and each locking plate being provided with a locking tongue.

[0022] The above-mentioned further design incorporates a double-locking plate (first and second locking plates) linkage design, with locking tongues on both plates, which can simultaneously lock both hooks of the bag. Compared with a single locking tongue structure, it has stronger impact resistance (avoiding breakage due to excessive force on a single locking tongue) and improves the anti-theft performance of the bag.

[0023] A further feature of this invention is that both the first locking plate and the second locking plate are provided with a first locking hole, the bolt is provided with a locking rod, the locking rod extends out of the bottom cover and is inserted into the first locking hole on both locking plates, the first locking plate is provided with a locking block, the second locking plate is provided with a second locking hole, and the locking block is inserted into the second locking hole.

[0024] By adopting the above-mentioned further configuration, the bolt and the double locking plate are connected through "block + first locking hole"; "block + second locking hole" ensures that the double locking plates move synchronously, ensuring that the movement distance of the two locking plates is consistent and the extension and retraction of the bolt are synchronized, avoiding the fault of "one side unlocked and the other side still locked" caused by the offset of a single locking plate, thus improving the stability of the double locking plate structure.

Detailed Implementation

[0026] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-12 As shown, this utility model discloses a bag lock, including a lock body 2 that cooperates with a lock hook 1. The lock body 2 has a housing 21 and a lock plate 22, a combination wheel assembly 23, and a button 24 disposed on the housing. The lock plate 22 is provided with a latch 221, and the lock plate 22 can slide horizontally to lock or unlock the lock hook 1. The combination wheel assembly 23 allows the lock plate 22 to slide when the combination is correct, and locks the lock plate 22 when the combination is incorrect. The combination wheel assembly 23 includes a rotatable inner wheel assembly 231 and a combination wheel assembly 232, a slidable bolt 233, and a main reset member 234 capable of resetting the bolt. The bolt 233 and the lock plate 22 slide synchronously in the horizontal direction. The button 24 is exposed on the upper surface of the outer shell 21 and is slidably arranged in the vertical direction. The button 24 and the bolt 233 form an inclined surface fit. The inner wheel assembly 231 is provided with multiple inner wheels, and the combination wheel assembly 232 is provided with multiple combination wheels. The combination wheels are exposed on the upper surface of the outer shell 21. When the password is correct, press button 24. Through the engagement with the inclined surface of bolt 233, push bolt 233 to move lock plate 22 in the unlocking direction so that bolt 221 disengages from lock hook 1. After releasing button 24, the main reset component 234 drives bolt 233 to move lock plate 22 in the locking direction to reset so that bolt 221 locks lock hook 1.

[0028] Specifically, the outer casing 21 is equipped with a password reset button 25. Each password wheel 2321 and its corresponding inner wheel 2311 are axially sliding and circumferentially linked through a snap-fit ​​structure. The password reset button 25 can push the inner wheel 2311 to slide relative to the password wheel 2321. The snap-fit ​​structure is a conventional setting for password wheel lock structures, usually achieved by the cooperation of an axially set groove and a block. When the block on the inner wheel slides into the groove of the password wheel, the two are circumferentially linked; when the inner wheel slides axially, the block slides out of the groove, and the circumferential linkage between the inner wheel and the password wheel is released. The password reset key 25 and button 24 are distributed at both ends of the password wheel assembly 232. The password reset key 25 is exposed on the upper surface of the outer shell 21 and slides vertically. The password reset key 25 forms an inclined surface engagement with the inner wheel push seat 2312 at one end of the inner wheel assembly 231. The bolt 233 is provided with an end seat 2331. The main reset component 234 is a spring, which is sleeved on the bolt 233 and abuts against the other end of the inner wheel assembly 231 and the end seat 2331. When the password reset key 25 is pressed down, it pushes the inner wheel push seat to slide the inner wheel 2311 through the inclined surface engagement with the inner wheel push seat, so that the locking structure is disengaged to release the circumferential linkage between the password wheel 2321 and the inner wheel 2311. When the password reset key 25 is released, the main reset component 234 drives the inner wheel assembly 231 to slide back to its original position, so that the locking structure is engaged to restore the circumferential linkage between the password wheel 2321 and the inner wheel 2311. A locking structure is provided between the password reset key 25 and the inner wheel push seat 2312. After the password reset key 25 is pressed down, the locking structure makes the password reset key 25 and the inner wheel push seat 2312 position and cooperate to maintain the pressed state of the password reset key 25. The password reset key 25 is provided with a first inclined surface 251 and a first locking surface 252 located at its upper end. The inner wheel push seat 2312 is provided with a second inclined surface 23121 and a second locking surface 23122 located at its lower end. The first inclined surface 251 and the second inclined surface 23121 form an inclined surface fit. The first locking surface 252 and the second locking surface 23122 form a locking structure. The locking surface is inclined. When the password reset key 25 is pressed down, the first inclined surface 251 and the second inclined surface 23121 come into contact, causing the inner wheel push seat 2312 to drive the inner wheel 2311 to slide until the first locking surface 252 and the second locking surface 23122 abut against each other, thus positioning the pressed password reset key 25. The end seat 2331 is fixed or integrally set with the bolt 233. The button 24 is provided with a third inclined surface 241 and the end seat 2331 is provided with a fourth inclined surface 2333. The third inclined surface 241 and the fourth inclined surface 2333 contact each other to form an inclined surface fit.

[0029] Specifically, the outer casing 21 includes a receiving chamber 213 formed by the cooperation of a base 211 and a top cover 212. The base 211 and the top cover 212 are connected by snaps or screws. The top cover 212 has a password cavity 2121, and the password wheel assembly 23 is installed inside the password cavity 2121. A bottom cover 2122 is provided at the bottom of the password cavity 2121, and the bottom cover 2122 is connected to the top cover 212 by snaps or screws. The locking plate 22 is slidably located below the bottom cover 2122. The button 24 and the password reset key are vertically slidably installed in the password cavity 2121, and a button reset component 28 is provided between the button 24 and the bottom cover 2122 below. The button reset component 28 is used to reset the button 24 upwards, and the password reset key 25 can also be driven upwards by a spring. The combination wheel 2321 has multiple circumferentially spaced slots 23211. The bottom cover 2122 has elastic levers 21221 corresponding to the positions of each combination wheel 2321. One end of each elastic lever 21221 is integrally connected to the bottom cover 2122, and the other end elastically presses against the outer circumference of the combination wheel 2321. When the combination wheel 2321 is rotated, the end of the elastic lever 21221 alternately engages or disengages from each slot 23211. The locking plate 22 includes a first locking plate 222 and a second locking plate 223 that are slidably disposed in the receiving chamber. The two locking plates are linked together, and each locking plate has a locking tongue 221. The first locking plate 222 and the second locking plate 223 are each provided with a first locking hole 224. The bolt 233 is provided with a locking rod 2332. The locking rod 2332 extends out of the bottom cover 2122 and is inserted into the first locking hole 224 on the two locking plates. The first locking plate 222 is provided with a locking block 2221, and the second locking plate 223 is provided with a second locking hole 2231. The locking block 2221 is inserted into the second locking hole 2231.

[0030] The lock body and lock hook of this invention are respectively installed on both sides of the bag, and work together to achieve locking and unlocking functions. The lock hook can also be a zipper.

[0031] The specific working principle is as follows: Password unlocking process When the correct password is entered, the inner wheel 2311 no longer obstructs the bolt 233. Pressing down on button 24 causes the third inclined surface 241 of button 24 to press against the fourth inclined surface 2333 of bolt 233, converting the vertical force into a horizontal force. This forces bolt 233 to compress the main reset component 234 and causes the lock plate 22 to slide in the unlocking direction, causing the bolt 221 to retract and disengage from the lock hook 1, thus completing the unlocking process. When button 24 is released, button reset component 28 pushes the button back, and the main reset component 234 drives bolt 233 and lock plate 22 to reset. The bolt 221 can then re-engage with the lock hook 1, restoring the lock.

[0032] When the password is incorrect, the inner wheel 2311 prevents the bolt 233 from sliding, the lock plate 22 cannot move and remains locked, and the bolt can lock the hook.

[0033] 2. Password reset process Press down the password reset button 25. The first inclined surface 251 of the password reset button 25 presses against the second inclined surface 23121 of the inner wheel push seat 2312, pushing the inner wheel assembly 231 to slide. The locking structure between the inner wheel 2311 and the password wheel 2321 is disengaged (circumferential linkage is released). After the first locking surface moves to below the second locking surface, the main reset component can cause the first locking surface and the second locking surface to form a top contact, completing the positioning. Keep the reset button in the down state. At this time, rotate the password wheel 2321: Since the inner wheel 2311 and the password wheel 2321 have been disengaged, a new password can be freely set (the elastic paddle 21221 and the gear slot 23211 cooperate to provide gear feedback). Then press the password reset button 25 again. The password reset button will be driven upward by the spring to reset, so that the password reset button 25 disengages from the locking structure of the inner wheel pusher. The main reset component 234 pushes the inner wheel assembly 231 and the inner wheel pusher to slide horizontally and reset. The inner wheel 2311 and the password wheel 2321 are then linked circumferentially again through the locking structure, and the new password takes effect. Of course, the locking structure is not required. During operation, the password reset button is pressed and held. After the password is reset, the password reset button can be released.

[0034] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0035] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
