Abstract
Description
Technical Field
[0001] This utility model relates to the field of luggage accessories technology, specifically to a luggage lock. Background Technology
[0002] In the luggage industry, locking systems play a crucial role in ensuring the safety of items inside and facilitating easy opening and closing. Early luggage locks were mostly simple hook-type or snap-on structures. Hook-type locks close by inserting a hook into a corresponding loop. While this method is simple, the hook can easily detach from the loop under external force, resulting in poor security and failing to effectively prevent accidental opening of the luggage. This is especially true during bumpy transport or in crowded environments, where items can easily be lost due to the lock coming loose. While snap-on locks offer some stability, they are cumbersome to operate, requiring manual tightening and loosening, which is extremely inconvenient when quick access to items is needed.
[0003] With increasing demands for both security and ease of use in luggage and bags, some relatively complex mechanical locks have emerged. For example, some mechanical locks use a key to open, where the key turns the lock cylinder, causing the bolt to move and controlling the lock's position. However, keys are easily lost or stolen, compromising the security of the luggage and bags. Furthermore, over long-term use, the lock cylinder of these locks is prone to rusting and jamming due to dust and moisture, affecting unlocking smoothness and resulting in high repair costs. Utility Model Content
[0004] The purpose of this invention is to provide a simple, practical, and highly stable bag lock to address the above problems.
[0005] To achieve the above objectives, this utility model discloses a bag lock, including a lock box. Its structural features include a locking rod passing through the upper part of the lock box, with a locking block and a control button block respectively located at both ends of the locking rod. A positioning plate coaxially rotating with the locking rod is provided on the locking rod inside the lock box. A locking block that moves up and down along the lock box is provided in the lock box below the locking rod. The positioning plate has a positioning slot that mates with the upper end plate of the locking block. A reset mechanism mates with the locking plate is provided in the lock box below the locking block. A control opening is provided on the outer wall of the middle part of the lock box, allowing the locking block to partially protrude.
[0006] With the above structure, the locking block and control button are connected by a locking rod. Combined with a positioning plate, locking block, and reset mechanism, a flexible and stable locking function is achieved. The positioning slot on the positioning plate, in conjunction with the locking block, provides reliable positioning when the lock is locked, preventing the locking rod from rotating arbitrarily and ensuring the security of the bag. The reset mechanism allows the locking block to automatically reset after operation, facilitating locking of the locking rod and improving operational convenience. The control opening provides users with a direct way to control the movement of the locking block, facilitating unlocking and other operations.
[0007] A type of luggage includes a left compartment and a right compartment, with the aforementioned luggage buckle installed on the left compartment. Its structural feature is that the right compartment has a locking slot that matches the locking block. By installing the buckle on the left compartment and providing a matching locking slot on the right compartment, this design concentrates the opening and closing control of the luggage on one side, making it convenient for the user. The left and right compartments, through the precisely matched buckle and locking slot, can close tightly, effectively preventing accidental opening during handling and ensuring the safety of the contents. At the same time, this single-sided buckle installation method also contributes to the simplicity and symmetry of the luggage's overall appearance.
[0008] Preferably, the lock box is a strip-shaped shell structure with an open bottom, and the front and rear side walls of the lower part of the lock box body are provided with locking slots. The reset mechanism is locked at the lower end of the lock box. A positioning chamber is provided in the upper part of the lock box body at the position of the locking rod. The side of the positioning chamber near the locking block has a positioning opening that matches the end of the locking block. By designing the lock box as a strip-shaped shell structure with an open bottom, the installation and maintenance of internal parts are facilitated. The locking slot design allows the reset mechanism to be easily locked at the lower end of the lock box, ensuring a firm and stable installation. At the same time, the positioning chamber and positioning opening provide precise guidance and positioning space for the movement of the locking block, further improving the stability and reliability of the lock during operation and reducing the probability of failure caused by the shaking or displacement of parts.
[0009] Preferably, the locking rod passes through the lock case body and extends from the front and rear side walls of the lock case at both ends. The control button is fixed to the locking rod body located on the front side of the lock case. The lock block is a strip-shaped stop and is vertically fixed to the end face of the locking rod away from the control button at its center. The control button rotates coaxially with the locking rod and the lock block. Because the locking rod passes through the lock case and extends to both ends, and the control button rotates coaxially with the lock block, the user can easily rotate the lock block by operating the control button, thus opening and closing the lock. This structural design is simple and intuitive to operate, conforms to ergonomic principles, greatly reduces the difficulty of operation for users, and improves the user experience. At the same time, the strip-shaped stop of the lock block provides a larger contact area when engaging with the lock, providing stronger locking force and enhancing the anti-theft performance of the bag.
[0010] Preferably, the positioning plate is a circular baffle with a mounting hole in its center that matches the diameter of the locking rod. The locking rod passes through the mounting hole and is fixedly connected to the positioning plate. Two positioning slots are symmetrically arranged radially on the positioning plate, extending from the side edge of the positioning plate towards the center of the plate. This circular baffle-shaped positioning plate provides a simple and stable structure. Its fixed connection to the locking rod through the mounting hole ensures synchronous rotation between the positioning plate and the locking rod. The two radially symmetrical positioning slots allow for bidirectional positioning with the locking block, ensuring timely positioning and locking regardless of the direction of rotation of the locking rod, thus improving the adaptability and reliability of the locking system.
[0011] Preferably, the locking block includes a limiting slider located within the lock housing and sliding vertically along the lock housing. The upper end of the limiting slider has a locking block that engages with a positioning slot, and the lower end of the limiting slider has a connecting post that engages with a reset mechanism. The limiting slider has a control groove corresponding to the position of the control opening. By employing a combination design of the limiting slider, locking block, and connecting post, the locking block ensures that it can only slide vertically along the lock housing, with a precise movement trajectory, preventing deviations or other abnormalities. The locking block's engagement with the positioning slot provides the locking function, and the connecting post connects to the reset mechanism for easy reset operation. The control groove corresponds to the control opening, allowing users to control the locking block using external tools or their fingers, making operation flexible and convenient.
[0012] Preferably, the reset mechanism includes a connecting base and two elastic claws disposed on the connecting base and engaged within the lock housing. A mounting seat is located in the middle of the connecting base, and a reset spring is mounted on the mounting seat. The reset spring is vertically oriented, with its upper end mounted on a connecting post at the lower end of the locking block. The reset mechanism utilizes a combination of the connecting base, elastic claws, and reset springs. The elastic claws engage with the lock housing's mounting opening, facilitating easy installation and quickly securing the connecting base to the bottom of the lock housing. The vertically oriented reset springs precisely provide a reset force to the locking block, ensuring it quickly returns to its initial locked position after unlocking, guaranteeing efficient operation of the locking system and improving its usability.
[0013] Preferably, the elastic claw is an L-shaped baffle. The bottom of the vertical plate of the L-shaped baffle is fixed to the connecting base, and the horizontal plate of the L-shaped baffle is engaged with the locking slot of the lock box. The L-shaped elastic claw allows for quick and accurate installation, and it is not prone to loosening or falling off during long-term use, ensuring the stability of the connection between the reset mechanism and the lock box, thereby guaranteeing the reliability of the entire locking system.
[0014] Preferably, the control opening is a rectangular opening and communicates with the interior of the lock box, and the size of the control opening is larger than the size of the control recess. The rectangular control opening, communicating with the interior of the lock box and being larger than the control recess, provides sufficient space for user operation. Users can easily operate the control recess of the locking block through the control opening, whether by pressing with their fingers or with the aid of some auxiliary tools, thus improving the flexibility and convenience of operation.
[0015] Preferably, the locking block has a first through hole in its control groove, and a second through hole corresponding to the first through hole is provided on the rear side wall of the lock box. The position of the second through hole corresponds to the position of the first through hole when the locking block is locked. By having the first through hole in the locking block's control groove correspond to the second through hole on the rear side wall of the lock box, and their positions correspond when locked, this design allows for additional locking or unlocking operations of the locking block when needed, by inserting a specific tool through the two through holes. This adds a backup operation method, improves the adaptability and operability of the locking system in special circumstances, and provides users with more security and operational options.
[0016] In summary, the beneficial effects of this utility model are as follows: This utility model has a simple structure and is easy to operate. By connecting the locking block and control button block with a locking rod, and in conjunction with a positioning plate, locking block, and reset mechanism, it achieves a flexible and stable locking function. The positioning slot on the positioning plate cooperates with the locking block to provide reliable positioning when the lock is in the locked state, preventing the locking rod from rotating arbitrarily and ensuring the safety of the bag. The reset mechanism allows the locking block to automatically reset after operation, facilitating locking of the locking rod and improving operational convenience. Furthermore, the control opening provides users with a direct way to control the movement of the locking block, facilitating unlocking and other operations. Attached Figure Description

[0027] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.
[0028] like Figure 1 - Figure 3As shown, this utility model includes a lock box 1, with a lock rod 2 passing through the upper part of the lock box 1. A reset mechanism 8 that cooperates with the lock plate is provided inside the lock box 1 at the lower end of the locking block 6. Locking blocks 3 and control buttons 4 are respectively provided at both ends of the lock rod 2. A positioning plate 5 that rotates coaxially with the lock rod 2 is also provided on the lock rod 2 inside the lock box 1. A locking block 6 that moves up and down along the lock box 1 is provided inside the lock box 1 at the lower part of the lock rod 2. At the same time, a positioning slot 7 that cooperates with the upper plate of the locking block 6 is provided on the positioning plate 5. In the design, the lock rod 2 passes through the body of the lock box 1 and extends out of the front and rear side walls of the lock box 1 at both ends. The control button 4 is fixed to the body of the lock rod 2 located on the front side of the lock box 1. The lock block 3 is a strip-shaped stop block and is vertically fixed to the end face of the lock rod 2 away from the control button 4. The control button 4 rotates coaxially with the lock rod 2 and the lock block 3. With the locking rod 2 passing through the lock box 1 and extending to both ends, the control button 4 and the locking block 3 rotate coaxially. The user can easily drive the locking block 3 to rotate by operating the control button 4, thus opening and closing the lock. This structural design is simple and intuitive to operate, conforms to ergonomic principles, greatly reduces the difficulty of operation for users, and improves the user experience. At the same time, the locking block 3, in the form of a strip-shaped stop, has a larger contact area when it cooperates with the lock opening 12, which can provide stronger locking force and enhance the anti-theft performance of the bag.
[0029] like Figure 1 - Figure 4As shown, the lock box 1 is a strip-shaped shell structure with an open bottom. The front and rear side walls of the lower part of the lock box 1 are provided with mounting holes 13, which are rectangular. The reset mechanism 8 is mounted at the lower end of the lock box 1. A positioning chamber 14 is provided in the upper part of the lock box 1 at the position of the lock rod 2. The positioning chamber 14 is usually a circular chamber and is adapted to the shape and size of the positioning plate 5. Usually, a circular opening is provided on the rear end face of the lock box 1 to facilitate the installation of the positioning plate 5. The circular opening corresponds to the position of the positioning chamber 14. In the design, the positioning plate 5 is a circular baffle and the middle of the positioning plate 5 is provided with a mounting hole that matches the diameter of the lock rod 2. The lock rod 2 passes through the mounting hole and is fixedly connected to the positioning plate 5. Two positioning slots 7 are provided radially symmetrically on the positioning plate 5. The two positioning slots 7 extend from the side edge of the positioning plate 5 towards the middle of the plate body. The circular baffle-shaped positioning plate 5 has a simple and stable structure. It is fixedly connected to the locking rod 2 through mounting holes, ensuring synchronous rotation between the positioning plate 5 and the locking rod 2. The two radially symmetrical positioning slots 7 can achieve bidirectional positioning with the locking block 17 of the locking block 6. Regardless of the direction of rotation of the locking rod 2, it can be positioned and locked in a timely manner, improving the adaptability and reliability of the locking system. During manufacturing, the positioning chamber 14 near the locking block 6 also has a positioning opening 15 adapted to the end of the locking block 6. The positioning chamber 14 and the positioning opening 15 provide precise guidance and positioning space for the movement of the locking block 6, further improving the stability and reliability of the locking system during operation and reducing the probability of malfunctions caused by component shaking or displacement.
[0030] like Figure 1 , Figure 3 as well as Figure 4As shown, the locking block 6 includes a limiting slider 16 located inside the lock box 1 and sliding along the vertical direction of the lock box 1. A locking block 17 is provided at the upper end of the limiting slider 16, passing through the positioning opening 15 on the positioning chamber 14. The locking block 17 passes through the positioning opening 15 and cooperates with the positioning slot 7 on the positioning plate 5. The lower end of the limiting slider 16 is provided with a connecting post 18 that cooperates with the reset mechanism 8. In this way, by adopting the combination design of the limiting slider 16, the locking block 17 and the connecting post 18, the limiting slider 16 ensures that the locking block 6 can only slide along the vertical direction of the lock box 1, with a precise movement trajectory, preventing abnormal situations such as deviation. The cooperation between the locking block 17 and the positioning slot 7 realizes the locking function. The connecting post 18 is connected to the reset mechanism 8, which facilitates the reset operation. In the design, a control opening 9 is provided on the outer wall of the middle part of the lock box 1, allowing the locking block 6 to be partially exposed. A control groove 19 corresponding to the control opening 9 is provided on the limiting slider 16. This alignment of the control groove 19 with the control opening 9 allows the user to easily control the locking block 6 using external tools or fingers, making operation flexible and convenient. During manufacturing, the control opening 9 is typically rectangular and connected to the interior of the lock box 1, and its size is larger than the control groove 19. This rectangular control opening 9, connected to the interior of the lock box 1 and larger than the control groove 19, provides sufficient space for user operation. Users can easily operate the control groove 19 of the locking block 6 through the control opening 9, whether using fingers or auxiliary tools, thus improving operational flexibility and convenience.
[0031] like Figure 1 and Figure 2 As shown, the control groove 19 of the locking block 6 also has a first through hole 23, and a second through hole 24 corresponding to the first through hole 23 is provided on the rear side wall of the lock box 1. The position of the second through hole 24 corresponds to the position of the first through hole 23 when the locking block 6 is locked. In this way, the first through hole 23 in the control groove 19 of the locking block 6 corresponds to the second through hole 24 on the rear side wall of the lock box 1, and the positions correspond in the locked state. This design allows for additional locking or unlocking operations of the locking block 6 by inserting a specific tool through the two through holes when needed, adding a backup operation method, improving the adaptability and operability of the locking system in special situations, and providing users with more security and operational options.
[0032] like Figure 3 and Figure 4As shown, the reset mechanism 8 includes a connecting base and two elastic claws 20 disposed on the connecting base and fitted inside the lock box 1. A mounting base 21 is provided in the middle of the connecting base, and a reset spring 22 is provided on the mounting base 21. The reset spring 22 is arranged vertically, and its upper end is mounted on the connecting post 18 at the lower end of the locking block 6. The connecting post 18 and the connecting post 22 are located on the same axis. Thus, the reset mechanism 8 adopts a combination of connecting base, elastic claws 20 and reset spring 22. The elastic claws 20 are fitted onto the locking slot 13 of the lock box 1, which is convenient for installation and can quickly fix the connecting base to the bottom of the lock box 1. The reset spring 22 is arranged vertically, which can accurately provide a reset force to the locking block 6, so that the locking block 6 can quickly return to the initial locked position after the unlocking operation, ensuring the efficient operation of the locking system and improving the efficiency of use. In the design, the aforementioned elastic claw 20 is an L-shaped baffle. The bottom of the vertical plate of the L-shaped baffle is fixed on the connecting base, and the horizontal plate of the L-shaped baffle is fitted into the mounting opening 13 of the lock box 1. Usually, the horizontal plates of the two elastic claws 20 face opposite directions, which makes it easier to fit them into the mounting openings 13 on the front and rear side walls of the lock box 1 respectively. The L-shaped elastic claw 20 can be installed quickly and accurately, and it is not easy to loosen or fall off during long-term use, thus ensuring the stability of the connection between the reset mechanism 8 and the lock box 1, and thus ensuring the reliability of the entire locking system.
[0033] like Figure 5 and Figure 6 As shown, a bag includes a left compartment 10 and a right compartment 11. The bag's buckle is bolted to the left compartment 10, while the right compartment 11 has a locking slot 12 that matches the locking block 3. By installing the buckle on the left compartment 10 and the right compartment 11 with the matching locking slot 12, this design concentrates the opening and closing control of the bag on one side, making it convenient for the user to operate. In use, the two compartments are joined together, allowing the locking block 3 to extend into the locking slot 12. By rotating the control knob 4, the locking block 3 and the locking slot 12 are misaligned, causing the two compartments to lock together. At the same time, the locking block 17 at the upper end of the locking block 6 engages with the positioning slot 7 of the positioning plate 5, thereby locking the buckle. In this way, the left and right compartments 11 can be tightly closed by the precisely matched buckle and locking slot 12, effectively preventing the bag from being accidentally opened during handling and ensuring the safety of the contents. At the same time, this single-sided buckle installation method also contributes to the simplicity and symmetry of the bag's overall appearance.
[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
