Abstract
Description
Technical Field
[0001] This invention relates to the field of luggage manufacturing technology, and in particular to an adaptive lock structure for luggage and its usage method. Background Technology
[0002] In the luggage industry, locks, as common switches, play a crucial role. Luggage is a delicate daily necessity, and the user experience of the lock directly impacts the overall user experience. However, in the current luggage industry, most lock structures are not designed to account for potential misalignment between the upper and lower shells or frames during use. Consequently, the fault tolerance of most current luggage lock structures is very low. When misalignment or large gaps occur between the upper and lower shells or frames, the lock may become stiff, jammed, or even unable to open or close, affecting both the lock structure and the normal use of the luggage. This can lead to a poor user experience and ultimately impact the market competitiveness of luggage products. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adaptive lock structure for bags. The lock structure has a simple principle, but can adaptively adjust the misalignment or gap between the upper and lower shells or the upper and lower frames of the bag. The lock structure has a high fault tolerance rate and can effectively improve the user experience of bag products.
[0004] Another object of the present invention is to provide a method of using the above-mentioned adaptive lock structure for bags.
[0005] The technical solution of the present invention is as follows: an adaptive lock structure for bags, comprising a first lock part and a second lock part that cooperate with each other. A first frame and a second frame are respectively provided on the two sides of the bag shell. The first lock part is provided on the first frame, and the second lock part is provided on the second frame. The first lock part is provided with a buckle plate, a connecting rod, and a sliding buckle. The middle part of the buckle plate is connected to one end of the sliding buckle through the connecting rod. A special-shaped spring is provided on one side of the connecting rod. The other end of the sliding buckle is a hook-shaped hook. A hook is provided on one side of the buckle plate. The hook has a lock hole and the hook is located below the hook. The second lock part is provided with a lock tongue that cooperates with the lock hole on the hook. A fastening part that cooperates with the hook is provided below the lock tongue. In this lock structure, a connecting rod and a sliding buckle are set in the first lock part, and a corresponding fastening part is set in the second lock part. During the locking process, the connecting rod drives the slider to gradually tighten and return the second lock part to its original position, thereby achieving an adaptive adjustment function. This solves the problem of stiffness and jamming caused by misalignment or gaps between the first and second lock parts and the upper and lower shells or frames of the bag. The goal is to improve the fault tolerance of the lock structure and improve the user experience.
[0006] One end of the connecting rod is hinged to the latch plate via a first rivet rod, and the other end of the connecting rod is connected to the sliding buckle via a second rivet rod. A shaped spring is sleeved between the first and second rivet rods. One end of the connecting rod can swing relative to the latch plate, and the other end can swing relative to the sliding buckle. Under the action of the shaped spring, the latch plate and the sliding buckle engage in an opening and closing motion. When locked, the latch plate and the sliding buckle are relatively closed, the shaped spring is compressed, and the latch plate and the sliding buckle cooperate with the second locking part to form a locked state. When unlocked, after the latch plate and the sliding buckle disengage from the second locking part, under the elastic force of the shaped spring, the latch plate and the sliding buckle open relative to each other, forming an unlocked state.
[0007] The first lock part also includes a first lock shell, a first lock base plate, and a first return spring. One side of the strike plate is hinged to the upper part of the first lock shell. The connecting rod and sliding buckle are located within the first lock shell. The bottom of the first lock shell is locked to the first lock base plate by screws. The first lock base plate and the strike plate are connected by the first return spring. The first lock base plate provides the mounting foundation for the entire first lock part and also forms a fixed mounting structure with the first frame (its specific installation method can be the same as a traditional lock structure). The first lock shell provides mounting space for the strike plate, connecting rod, and sliding buckle, allowing the entire first lock part to form a complete structure. Simultaneously, the strike plate is hinged to the top surface of the first lock shell, and the top and side surfaces of the first lock shell provide movement space for the strike plate and sliding buckle, respectively. The first return spring connects the strike plate and the first lock base plate, further providing spring force for the strike plate to return during the unlocking process, enabling rapid unlocking.
[0008] The top surface of the first lock base plate has two protrusions, each with a first return spring. The other end of the first return spring is connected to the bottom surface of the lock plate. The protrusions help to better fix the first return springs. The two first return springs are respectively located on the outside of the connecting rod and the sliding buckle to avoid interfering with the movement of the connecting rod and the sliding buckle.
[0009] The first lock housing is a frame-like structure with an opening on one side. The lock hook on the strike plate and the latch on the sliding buckle are exposed on the open side of the first lock housing. The open side faces the second lock part, and the lock hook on the strike plate and the latch on the sliding buckle extend from the open side to engage with the second lock part.
[0010] The locking tongue is a pair, including a first locking tongue and a second locking tongue arranged in a split configuration. The outer ends of the first and second locking tongues are each equipped with a second return spring. The first and second locking tongues can slide relative to each other, forming an open or closed state. During locking, under the push of the hook on the strike plate, the first and second locking tongues first open relative to each other. When the hook of the strike plate enters between the first and second locking tongues, the first and second locking tongues quickly close under the action of the second return springs at their two outer ends. The first and second locking tongues are then inserted into the lock holes on the hook, forming a locking structure.
[0011] A button is provided on the outer side of the latch, and the contact surface between the latch and the button is a wedge-shaped surface. The button is mainly used by the user to operate when unlocking. When unlocking is required, the user presses the button, and the button slides towards the latch inside the second lock part. Under the action of the wedge-shaped surface, the end of the button pushes the first and second latches to slide in the opening direction, thereby disengaging from the keyhole. After the lock hook on the strike plate disengages from the latch, it quickly opens upward under the action of the first return spring and the irregular spring. Subsequently, the sliding buckle also quickly disengages from the latching part under the action of the irregular spring and the connecting rod, thus forming the unlocked state.
[0012] The second lock part also includes a second lock shell and a second lock base plate. The bottom of the second lock shell is locked to the second lock base plate by screws. The bolt and button are installed in the space between the second lock shell and the second lock base plate. The bolt is slidably installed on the second lock base plate, and its two outer ends are connected to the inner wall of the second lock shell by second return springs. The button is also slidably installed on the second lock base plate, and the sliding direction of the button is perpendicular to the sliding direction of the bolt. One side of the button is exposed on the outside of the second lock shell. The second lock base plate provides the mounting base for the entire second lock part and also forms a fixed mounting structure with the second frame (its specific installation method can be the same as that of a traditional lock structure). The second lock shell provides mounting space for the bolt and button, allowing the entire second lock part to form a complete structure. Furthermore, when the entire lock structure uses a combination lock, the combination lock is also installed in the space between the second lock shell and the second lock base plate (the specific installation and operation method of the combination lock is the same as that of a traditional combination lock).
[0013] On the second lock base plate, a first through hole is provided below the bolt, and the outer edge of the first through hole forms a fastening part. In the second lock housing, a second through hole is provided above the bolt, and a notch is provided on the side wall of the second lock housing below the outer side of the second through hole, corresponding to the outer side of the fastening part. When locked, the lock hook on the strike plate enters the second lock housing through the second through hole, gradually contacts the bolt, and forms a locking state with the bolt. The sliding buckle enters the second lock housing through the notch on the side wall of the second lock housing until it engages with the fastening part, completing its self-adjusting process.
[0014] The usage method of the above-mentioned adaptive lock structure for bags is as follows:
[0015] When locking is required, press down the strike plate. The strike plate drives the sliding buckle to retract toward the second locking part via a connecting rod. During the retraction process, the hook at the end of the sliding buckle gradually engages with the engaging part, thereby causing the second locking part to gradually tighten toward the first locking part. The second locking part gradually returns to its original position, realizing the adaptive adjustment of misalignment or gap between the first frame and the second frame. Continue pressing down the strike plate, and the hook at one end of the strike plate gradually contacts the bolt in the second locking part. After the bolt gradually slides to make way for the hook, it enters the lock hole of the hook to form a locking structure, and locking is completed at this time.
[0016] When unlocking is required, press the button in the second locking part to drive the bolt to slide open. The hook of the strike plate first disengages from the bolt, and then, under the action of the irregular spring, the sliding buckle extends outward and disengages from the strike plate, thus completing the unlocking process.
[0017] The principle of the aforementioned adaptive lock structure for bags and its usage is as follows: the first lock part and the second lock part are respectively installed at corresponding positions on the first frame and the second frame. By setting a connecting rod and a sliding buckle on the locking plate of the first lock part, and setting a matching fastening part in the second lock part, the second lock part can be gradually tightened and returned to its original position by driving the slider through the connecting rod during the locking process, thereby achieving the function of adaptive adjustment. This solves the problem of stiffness and jamming caused by possible misalignment or gaps between the first lock part and the second lock part and the upper and lower frames, thereby improving the fault tolerance of the lock structure and improving the user experience. During the use of the lock structure, when locking is required, the user presses down the strike plate. The strike plate, via a connecting rod, drives the sliding buckle to retract towards the second locking part. During the retraction, the hook at the end of the sliding buckle gradually engages with the locking part, thereby causing the second locking part to gradually tighten towards the first locking part, allowing the second locking part to gradually return to its original position (i.e., the second locking part gradually returns to the position corresponding to the first locking part), achieving adaptive adjustment of the misalignment or gap between the first and second frames. If the user continues to press down the strike plate, the hook at one end of the strike plate gradually contacts the bolt in the second locking part. Under the push of the hook, the first and second bolts open relative to each other first, and then the hook of the strike plate enters the first and second bolts... When the latches are closed, the first and second latches close rapidly under the action of the second return springs at their outer ends. The first and second latches are inserted into the keyholes on the lock hook, forming a locking structure, thus completing the locking. When unlocking is required, the user presses the button, which slides towards the latch inside the second lock part. Under the action of the wedge-shaped surface, the end of the button pushes the first and second latches to slide in the opening direction, thereby disengaging from the keyhole. This causes the lock hook on the strike plate to first disengage from the latch's restriction and then quickly open upwards under the action of the first return spring and the shaped spring. Subsequently, the sliding buckle also quickly disengages from the latching part under the action of the shaped spring and the connecting rod, thus forming the unlocked state, thus completing the unlocking.
[0018] Compared with the prior art, the present invention has the following advantages:
[0019] The adaptive lock structure and its operation method used in this bag are achieved by setting a connecting rod and a sliding buckle on the locking plate of the first lock part, and setting a matching fastening part in the second lock part. During the locking process, the connecting rod drives the slider to gradually tighten and return the second lock part to its original position, thereby achieving an adaptive adjustment function. This solves the problem of stiffness and jamming caused by misalignment or gaps between the first and second lock parts and the upper and lower frames, thereby improving the fault tolerance of the lock structure and improving the user experience.
[0020] The adaptive lock structure used in this bag is simple in principle, easy to operate, and flexible in use. Applying it to bags provides users with a good user experience and can help improve the market competitiveness of bag products. Attached Figure Description

Detailed Implementation
[0038] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.
[0039] Example
[0040] This embodiment describes an adaptive lock structure for bags, such as... Figure 1 As shown, the case includes a first locking part 1 and a second locking part 2 that cooperate with each other. A first frame 4 and a second frame 5 are respectively provided on the two sides of the case shell 3. The first locking part is located on the first frame, and the second locking part is located on the second frame. Figure 12 As shown, the first locking part mates with the first inner pad 6 and is secured to the first frame by screws 8. The second locking part mates with the second inner pad 7 and is secured to the second frame by screws 8 (the installation method is the same as that of a traditional lock). After installation, when the first and second locking parts are engaged and locked, the state and structure of the bag are as follows. Figure 13 or Figure 14 As shown.
[0041] The specific structures of the first locking part and the second locking part are as follows:
[0042] like Figures 2 to 4 As shown, the first lock part includes a strike plate 9, a connecting rod 10, and a sliding buckle 11. The middle of the strike plate is connected to one end of the sliding buckle via the connecting rod. A shaped spring 12 is provided on one side of the connecting rod. The other end of the sliding buckle is a hook-shaped hook 11-1. A hook 9-1 is provided on one side of the strike plate, and the hook has a lock hole 9-2. The hook is located below the hook (e.g., ...). Figure 2 (as shown); as Figure 5 or Figure 6As shown, the second lock part is provided with a latch (including a first latch 13 and a second latch 14) that mates with the lock hole on the lock hook. Below the latch is a latching part 15 that mates with the hook. In this lock structure, by setting a connecting rod and a sliding buckle in the first lock part and setting a matching latching part in the second lock part, the second lock part can be gradually tightened and returned to its original position by driving the slider through the connecting rod during the locking process. This achieves an adaptive adjustment function, solving the problem of stiffness and jamming caused by misalignment or gaps between the first and second lock parts due to the upper and lower shells or upper and lower frames of the bag. This improves the fault tolerance of the lock structure and enhances the user experience. One end of the connecting rod is hinged to the lock plate through a first rivet rod 16, and the other end of the connecting rod is connected to the sliding buckle through a second rivet rod 17. A special-shaped spring is sleeved between the first rivet rod and the second rivet rod. The linkage has one end that can swing relative to the strike plate and the other end that can swing relative to the sliding buckle. Under the action of a shaped spring, the strike plate and the sliding buckle open and close. When locked, the strike plate and the sliding buckle are relatively closed, the shaped spring is compressed, and the strike plate and the sliding buckle cooperate with the second locking part to form a locked state. When unlocked, after the strike plate and the sliding buckle disengage from the second locking part, under the elastic force of the shaped spring, the strike plate and the sliding buckle open relative to each other, forming an unlocked state. The first locking part also includes a first lock housing 18, a first lock base plate 19, and a first return spring 20. One side of the strike plate is hinged to the upper part of the first lock housing. The linkage and the sliding buckle are located in the first lock housing. The bottom of the first lock housing is locked to the first lock base plate by screws. The first lock base plate and the strike plate are connected by the first return spring. The first lock base plate provides the mounting foundation for the entire first lock assembly and also forms a fixed mounting structure with the first frame (its specific installation method can be the same as that of a traditional lock structure). The first lock shell provides mounting space for the strike plate, connecting rod, and sliding buckle, allowing the entire first lock assembly to form a complete structure. Simultaneously, the strike plate is hinged to the top surface of the first lock shell, and the top and side surfaces of the first lock shell provide movement space for the strike plate and sliding buckle, respectively. The first return spring connects between the strike plate and the first lock base plate, further providing spring force for the strike plate to return during unlocking, achieving rapid unlocking. The top surface of the first lock base plate has two protrusions 19-1, each with a first return spring. The other end of the first return spring is connected to the bottom surface of the strike plate. The protrusions facilitate better fixation of the first return springs. The two first return springs are respectively located on the outside of the connecting rod and the sliding buckle, avoiding interference with their movement. Figure 3 As shown, the first lock housing is a frame-like structure with an opening on one side. The lock hook on the strike plate and the latch on the sliding buckle are exposed on the open side of the first lock housing (e.g., Figure 2 (As shown). The opening side faces the second locking part, and the locking hook on the locking plate and the buckle on the sliding buckle extend from the opening side to cooperate with the second locking part.
[0043] like Figures 5 to 7 As shown, there is a pair of latches, including a first latch 13 and a second latch 14 arranged in a split configuration. The outer ends of the first and second latches are each provided with a second return spring 21. The first and second latches can slide relative to each other, forming an open or closed state. During locking, under the push of the latch hook on the strike plate, the first and second latches first open relative to each other. When the latch hook of the strike plate enters between the first and second latches, the first and second latches quickly close under the action of the second return springs at their two outer ends, inserting into the lock holes on the latch hook to form a locking structure. A button 22 is provided on the outer side of the latch, and the contact surface between the latch and the button is a wedge-shaped surface 23 (e.g., ...). Figure 7 As shown, the button is mainly used by the user to unlock the lock. When unlocking is needed, the user presses the button, which slides towards the bolt inside the second lock part. Under the action of the wedge-shaped surface, the end of the button pushes the first and second bolts to slide in the opening direction, thereby disengaging from the keyhole. After the lock hook on the strike plate disengages from the bolt, it quickly opens upwards under the action of the first return spring and the irregular spring. Subsequently, the sliding latch also quickly disengages from the latching part under the action of the irregular spring and the connecting rod, thus forming the unlocked state. The second lock part also includes a second lock shell 24 and a second lock base plate 25. The bottom of the second lock shell is locked to the second lock base plate by screws. The bolt and the button are installed in the space between the second lock shell and the second lock base plate. The bolt is slidably installed on the second lock base plate. The two outer ends of the bolt are connected to the inner wall of the second lock shell through the second return spring. The button is also slidably installed on the second lock base plate. The sliding direction of the button is perpendicular to the sliding direction of the bolt, and one side of the button is exposed on the outside of the second lock shell. The second lock base plate provides the mounting foundation for the entire second lock assembly and also forms a fixed mounting structure with the second frame (its specific installation method is the same as that of a traditional lock structure); the second lock shell provides mounting space for the bolt and pushbutton, allowing the entire second lock assembly to form a complete structure; furthermore, when the entire lock structure adopts a combination lock method, the combination lock is also installed in the space between the second lock shell and the second lock base plate (the specific installation and operation methods of the combination lock are the same as those of a traditional combination lock). Figure 5 or Figure 6 As shown, on the second lock base plate, a first through hole 26 is provided below the bolt, and a fastening part 15 is formed on the outer edge of the first through hole; in the second lock housing, a second through hole 27 is provided above the bolt, and a notch 28 is provided on the side wall of the second lock housing below the outer side of the second through hole, corresponding to the outer side of the fastening part. When locked, the lock hook on the lock plate enters the second lock housing through the second through hole, gradually contacts the bolt, and forms a locking state with the bolt. The sliding buckle enters the second lock housing through the notch on the side wall of the second lock housing until it engages with the fastening part, completing its adaptive adjustment process.
[0044] The usage method of the above-mentioned adaptive lock structure for bags is as follows:
[0045] When locking is required, press down the strike plate. The strike plate drives the sliding buckle to retract toward the second locking part via a connecting rod. During the retraction process, the hook at the end of the sliding buckle gradually engages with the engaging part, thereby causing the second locking part to gradually tighten toward the first locking part. The second locking part gradually returns to its original position, realizing the adaptive adjustment of misalignment or gap between the first frame and the second frame. Continue pressing down the strike plate, and the hook at one end of the strike plate gradually contacts the bolt in the second locking part. After the bolt gradually slides to make way for the hook, it enters the lock hole of the hook to form a locking structure, and locking is completed at this time.
[0046] When unlocking is required, press the button in the second locking part to drive the bolt to slide open. The hook of the strike plate first disengages from the bolt, and then, under the action of the irregular spring, the sliding buckle extends outward and disengages from the strike plate, thus completing the unlocking process.
[0047] The principle of the aforementioned adaptive lock structure for bags and its usage is as follows: the first lock part and the second lock part are respectively installed at corresponding positions on the first frame and the second frame. By setting a connecting rod and a sliding buckle on the locking plate of the first lock part, and setting a matching fastening part in the second lock part, the second lock part can be gradually tightened and returned to its original position by driving the slider through the connecting rod during the locking process, thereby achieving the function of adaptive adjustment. This solves the problem of stiffness and jamming caused by possible misalignment or gaps between the first lock part and the second lock part and the upper and lower frames, thereby improving the fault tolerance of the lock structure and improving the user experience. During the use of the lock structure, when locking is required, the user presses down the strike plate. The strike plate, via a connecting rod, drives the sliding buckle to retract towards the second locking part. During the retraction, the hook at the end of the sliding buckle gradually engages with the locking part, thereby causing the second locking part to gradually tighten towards the first locking part, allowing the second locking part to gradually return to its original position (i.e., the second locking part gradually returns to the position corresponding to the first locking part), achieving adaptive adjustment of the misalignment or gap between the first and second frames. If the user continues to press down the strike plate, the hook at one end of the strike plate gradually contacts the bolt in the second locking part. Under the push of the hook, the first and second bolts open relative to each other first, and then the hook of the strike plate enters the first and second bolts... When the latches are closed, the first and second latches close rapidly under the action of the second return springs at their outer ends. The first and second latches are inserted into the keyholes on the lock hook, forming a locking structure, thus completing the locking. When unlocking is required, the user presses the button, which slides towards the latch inside the second lock part. Under the action of the wedge-shaped surface, the end of the button pushes the first and second latches to slide in the opening direction, thereby disengaging from the keyhole. This causes the lock hook on the strike plate to first disengage from the latch's restriction and then quickly open upwards under the action of the first return spring and the shaped spring. Subsequently, the sliding buckle also quickly disengages from the latching part under the action of the shaped spring and the connecting rod, thus forming the unlocked state, thus completing the unlocking.
[0048] As described above, the present invention can be well implemented. The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention; that is, all equivalent changes and modifications made in accordance with the content of the present invention are covered by the scope of protection claimed in the claims of the present invention.

The strike plate drives the sliding buckle to retract toward the second locking part via a connecting rod. During the retraction process, the hook at the end of the sliding buckle gradually engages with the engaging part, thereby causing the second locking part to gradually tighten toward the first locking part. The second locking part gradually returns to its original position, realizing the adaptive adjustment of misalignment or gap between the first frame and the second frame. Continue pressing down the strike plate, and the hook at one end of the strike plate gradually contacts the bolt in the second locking part. After the bolt gradually slides to make way for the hook, it enters the lock hole of the hook to form a locking structure, and locking is completed at this time. When unlocking is required, press the button in the second locking part to drive the bolt to slide open. The hook of the strike plate first disengages from the bolt, and then, under the action of the irregular spring, the sliding buckle extends outward and disengages from the strike plate, thus completing the unlocking process.
