Description

Technical Field

[0001] The present invention belongs to the technical field of single-shoulder bags, and particularly relates to a modular intelligent anti-theft single-shoulder bag and its usage method. Background Art

[0002] A single-shoulder bag is a portable bag that bears force on one side of the shoulder. It is divided into a single-shoulder sling bag and a cross-body bag, and is suspended on one side of the body through an adjustable shoulder strap, combining portability and practicality. Its materials are diverse, including canvas, cotton and linen, nylon, and leather, etc. Among them, the leather style has an elegant texture and is suitable for business scenarios, the nylon style is light and waterproof and suitable for travel, and the canvas style is wear-resistant and casual and suitable for daily use. In terms of design, it focuses on layered storage. The main bag can accommodate large items such as books and electronic devices, and the front bag and inner bag are convenient for classifying and storing small items such as keys and mobile phones. The styles cover simple, sporty, business and other styles, such as chain bags, diamond-checked bags, tote bags, etc., meeting the needs of multiple scenarios such as commuting, business trips, and shopping.

[0003] Conventional single-shoulder bags have limited capacity. Generally, the opening methods are the upward-flipping type or the zipper type. For the zipper type of opening method, in order to achieve anti-theft, a locking method is used to achieve anti-theft, but this method is complex to open and the key is easy to lose, making it inconvenient to use. The upward-flipping single-shoulder bag is limited by its structural form and generally uses a simple buckle type or a built-in lock core method to achieve anti-theft. The former has limited anti-theft ability, the latter has a relatively complex structure, and the opening is complex, and modular installation cannot be achieved, that is, when anti-theft is not required, it can be used as an ordinary single-shoulder bag, and improvement is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a modular intelligent anti-theft single-shoulder bag and its usage method to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A modular intelligent anti-theft single-shoulder bag, including a leather bag body, a leather bag cover connected to the top end of the leather bag body by stitching, and shoulder straps installed at both ends of the leather bag body through buckles. U-shaped magnets are fixedly installed at the overlapping parts of the leather bag body and the leather bag cover. Card slots are opened on both the left and right sides of the U-shaped magnet. A module frame is arranged on the outer side surface of the U-shaped magnet. Fixedly installed on both the left and right sides of the inner side surface of the module frame are clamping blocks. The module frame is movably clamped between the clamping blocks and the card slots. The module frame moves up and down relative to the U-shaped magnet. Transverse guide rails are installed on both the left and right sides near the top end of the module frame. A longitudinal guide rail is fixedly installed in the middle of the bottom end of the module frame. An anti-theft component is movably clamped inside the longitudinal guide rail. The left and right sides of the top end of the anti-theft component are movably clamped with the two transverse guide rails.

[0006] When in normal use, this single-shoulder bag can be used as a normal single-shoulder bag, and modular installation is only carried out when anti-theft is required.

[0007] As a further technical solution of the present invention, when the two U-shaped magnets are adsorbed and connected to each other, the module holder is movably clamped between the two U-shaped magnets. When the two U-shaped magnets are not adsorbed to each other, the module holder is not movably clamped between the two U-shaped magnets.

[0008] When the single-shoulder bag is in normal use, the opening and closing of the single-shoulder bag can be realized through the adsorption connection of the two U-shaped magnets, and it is used as a normal single-shoulder bag. Only when anti-theft is required, the device can be kept in a closed state, that is, when the two U-shaped magnets are in an adsorbed state with each other, a module holder is installed at the bottom end of the U-shaped magnet to achieve anti-theft.

[0009] As a further technical solution of the present invention, the anti-theft component includes a movable frame. The movable frame is located below the module holder. A limiting rod is fixedly installed in the middle of the top end of the movable frame. A limiting hole is opened at the bottom end of the longitudinal guide rail. The limiting rod passes through the limiting hole and is movably sleeved with the limiting hole. A longitudinal guide block is movably clamped inside the longitudinal guide rail. The bottom end of the longitudinal guide block is connected to the top end of the limiting rod.

[0010] As a further technical solution of the present invention, a push rod is fixedly installed in the middle of the bottom end of the movable frame. First fixing seats are fixedly installed on the left and right sides of the top end of the movable frame. One end of each first fixing seat away from the movable frame is movably connected to a connecting rod through a rotating shaft.

[0011] As a further technical solution of the present invention, one end of each connecting rod away from the first fixing seat is movably connected to a second fixing seat through a rotating shaft. The anti-theft component further includes a transverse guide block. The transverse guide block is movably clamped with the transverse guide rail. The transverse guide block moves left and right relative to the transverse guide rail. The bottom end of the transverse guide block is connected to the top end of the second fixing seat.

[0012] As a further technical solution of the present invention, a limiting spring is fixedly installed at one end of the inner cavity of the transverse guide rail. The other end of the limiting spring is connected to one end of the transverse guide block. A limiting frame is fixedly installed at the top end of each transverse guide block. Guide balls are fixedly installed at one end of the two limiting frames close to each other.

[0013] When anti-theft is required, the module frame can be aligned with the bottom end of the U-shaped magnet, and the module frame can be pushed into the module frame from the bottom end of the U-shaped magnet. At this time, the module frame moves upward, and the left and right ends of the U-shaped magnet exert force on the guide balls. At this time, the two guide balls are subjected to thrust, that is, the two guide balls are driven to move relatively apart. At this time, the limit spring can be compressed, and the two lateral guide blocks are relatively apart, and at the same time, the two connecting rods at the bottom are driven to deflect in the direction away from each other, and an upward thrust is applied to the movable frame at the bottom until the module frame is completely engaged with the U-shaped magnet. At this time, the guide ball moves to the top and is no longer subjected to the force from the U-shaped magnet. The limit spring automatically resets, and at the same time, the two guide balls are driven to move relatively close together until the guide balls are completely located above the module frame, completing the modular installation process. At this time, the two U-shaped magnets are restricted by the module frame, and the two U-shaped magnets cannot be separated, thus completing the locking process.

[0014] By utilizing the cooperation between the card slot and the module frame on the traditional magnetic installation method, and by the cooperation between the module frame and the anti-theft component, the device can quickly complete modular installation. At the same time, after the installation is completed, the two U-shaped magnets cannot be separated, completing the anti-theft opening, and cannot be unlocked by normal means. The modular installation ensures that the anti-theft function of the shoulder bag is activated only when needed, which will not affect normal use and improve practicality.

[0015] As a further technical solution of the present invention, when the limit spring is in the initial state, the distance between the two guide balls is at the minimum value, and the longitudinal guide block is at the lowest point. At this time, the distance between the two guide balls is smaller than the width of the U-shaped magnet.

[0016] As a further technical solution of the present invention, when the module frame and the U-shaped magnet are fully installed, the limit spring is in an initial state, and the two limit frames are both located at the top position between the two U-shaped magnets.

[0017] When unlocking is required, the push rod can be pressed upward to move the movable frame and the longitudinal guide block upward. At this time, the first fixed seat moves upward accordingly, and drives the two connecting rods to deflect in the direction away from each other, and applies pulling force to the two lateral guide blocks at the top. At this time, the two lateral guide blocks move away from each other, and drive the two guide balls away from each other, releasing the limiting process on the top of the U-shaped magnet. At this time, the guide balls no longer limit the U-shaped magnet. After maintaining the current state, pull out the module frame downward until the module frame is completely separated from the U-shaped magnet, and the unlocking process is completed.

[0018] By utilizing simple upward and downward pulling movements and the cooperation between the anti-theft component, the module frame and the U-shaped magnet, the device can be quickly unlocked. The entire unlocking process does not require the use of complex unlocking methods such as keys required by traditional devices. At the same time, it can prevent the shoulder bag from being opened by criminals, achieve anti-theft while simplifying the opening method, and improve safety and convenience.

[0019] By reusing the unlocking process, that is, after the shoulder bag is unlocked, the module frame and the U-shaped magnet can be separated. At this time, the shoulder bag is in a normal state and can be opened and closed normally by adsorption through the U-shaped magnet. After disassembly, the module frame can be put into the inside of the U-shaped magnet and used as a normal shoulder bag. No complicated anti-theft structure is set on the shoulder bag, so that the shoulder bag can be switched between the anti-theft state and the normal state, further improving its applicable scenarios.

[0020] A method for using a modular intelligent anti-theft shoulder bag comprises the following steps:

[0021] S1: When anti-theft is required, the bag cover needs to be closed to keep the two U-shaped magnets in the adsorption state. At this time, the module frame is pushed in from the bottom to complete the engagement between the card block and the card slot. When the module frame is pushed upward, the guide ball is then acted upon by the module frame, and the two guide balls are relatively separated.

[0022] S2: At this time, the limit spring can be compressed and drive the two lateral guide blocks to move away from each other until the two connecting rods deflect in the direction away from each other and exert tension on the movable frame, and the movable frame rises accordingly until the module frame and the U-shaped magnet are completely installed, and the guide ball is no longer subjected to the lateral thrust of the module frame;

[0023] S3: The limit spring automatically resets and drives the two guide balls to approach each other, thus completing the clamping between the module frame and the anti-theft component and completing the fixing process. At this time, the module frame prevents the two U-shaped magnets from separating from each other, thus completing the anti-theft process.

[0024] S4: When unlocking, the push rod is pushed upward to drive the movable frame to move upward. At this time, the limit spring is compressed and drives the two guide balls to move away from each other. After the limit process between the U-shaped magnet is released, the module frame can be pulled out downward to release the connection between the module frame and the U-shaped magnet, completing the unlocking.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) The present invention utilizes the cooperation between the card slot and the module holder in the traditional magnetic attraction installation method, and through the cooperation between the module holder and the anti-theft component, enabling the device to complete modular installation quickly. After installation, the two U-shaped magnets cannot be separated, completing the anti-theft activation and cannot be unlocked through normal means. The modular installation enables the shoulder bag to activate the anti-theft function only when needed, without affecting normal use, thus improving practicality.

[0027] (2) The present invention enables the device to complete unlocking quickly by utilizing simple upward and downward pulling actions and the cooperation between the anti-theft component, the module holder, and the U-shaped magnets. The entire unlocking process does not require complex unlocking methods such as using keys in traditional devices. At the same time, it can prevent the shoulder bag from being opened by lawbreakers, simplifying the opening method while achieving anti-theft, thereby improving safety and convenience.

[0028] (3) The present invention re-utilizes the unlocking process. That is, after the shoulder bag is unlocked, the module holder and the U-shaped magnets can be separated. At this time, the shoulder bag is in a normal state and can be opened and closed normally by magnetic attraction of the U-shaped magnets. After disassembly, the module holder can be placed inside the U-shaped magnets and used as an ordinary shoulder bag. Without setting complex anti-theft structures in the shoulder bag, the shoulder bag can be switched between anti-theft and normal states, further expanding its applicable scenarios.

Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0040] As Figures 1 to 9 shown, in the embodiment of the present invention, a modular intelligent anti-theft single-shoulder bag includes a leather bag body 1 and a leather bag cover 2 connected to the top of the leather bag body 1 by stitches, and shoulder straps 3 installed at both ends of the leather bag body 1 through buckles. U-shaped magnets 4 are fixedly installed at the overlapping joints of the leather bag body 1 and the leather bag cover 2. Card slots 5 are provided on both the left and right sides of the U-shaped magnet 4. A module holder 6 is provided on the outer side of the U-shaped magnet 4. Card blocks 7 are fixedly installed on both the left and right sides of the inner side of the module holder 6. The module holder 6 is movably clamped between the card block 7 and the card slot 5, and the module holder 6 is displaced up and down relative to the U-shaped magnet 4. Horizontal guide rails 8 are installed on both the left and right sides of the module holder 6 near the top. A vertical guide rail 9 is fixedly installed in the middle of the bottom end of the module holder 6. An anti-theft component 12 is movably clamped inside the vertical guide rail 9. The left and right sides of the top end of the anti-theft component 12 are movably clamped with the two horizontal guide rails 8.

[0041] During normal use, this single-shoulder bag can be used as a normal single-shoulder bag, and modular installation is only carried out when anti-theft is required.

[0042] As Figure 3 and Figure 4 as well as Figure 5 shown, when the two U-shaped magnets 4 are adsorbed and connected to each other, the module holder 6 is movably clamped between the two U-shaped magnets 4. When the two U-shaped magnets 4 are not adsorbed to each other, the module holder 6 is not movably clamped between the two U-shaped magnets 4.

[0043] When the single-shoulder bag is in normal use, the opening and closing of the single-shoulder bag can be realized through the adsorption connection of two U-shaped magnets 4, and it can be used as a normal single-shoulder bag. Only when anti-theft is required, the device can be kept in the closed state, that is, when the two U-shaped magnets 4 are in the state of mutual adsorption, a module holder 6 is installed at the bottom end of the U-shaped magnet 4 for realizing anti-theft.

[0044] As Figure 6 and Figure 7 as well as Figure 8 and Figure 9 shown, the anti-theft component 12 includes a movable frame 121. The movable frame 121 is located below the module holder 6. A limiting rod 123 is fixedly installed in the middle of the top end of the movable frame 121. A limiting hole 11 is opened at the bottom end of the longitudinal guide rail 9. The limiting rod 123 passes through the limiting hole 11 and is movably sleeved with the limiting hole 11. A longitudinal guiding block 124 is movably clamped inside the longitudinal guide rail 9. The bottom end of the longitudinal guiding block 124 is connected to the top end of the limiting rod 123. A push rod 122 is fixedly installed in the middle of the bottom end of the movable frame 121. First fixing seats 125 are fixedly installed on both the left and right sides of the top end of the movable frame 121. One end of each first fixing seat 125 away from the movable frame 121 is movably connected to a connecting rod 1210 through a rotating shaft. One end of each connecting rod 1210 away from the first fixing seat 125 is movably connected to a second fixing seat 126 through a rotating shaft. The anti-theft component 12 further includes a transverse guiding block 127. The transverse guiding block 127 is movably clamped with the transverse guide rail 8. The transverse guiding block 127 moves left and right relative to the transverse guide rail 8. The bottom end of the transverse guiding block 127 is connected to the top end of the second fixing seat 126. Limiting springs 10 are fixedly installed at one end of the inner cavity of the transverse guide rail 8. The other end of each limiting spring 10 is connected to one end of the transverse guiding block 127. Limiting frames 128 are fixedly installed at the top ends of the transverse guiding blocks 127. Guide balls 129 are fixedly installed at one end of each two limiting frames 128 close to each other.

[0045] Embodiment: When anti-theft is required, the module frame 6 can be aligned with the bottom end of the U-shaped magnet 4, and the module frame 6 can be pushed into the module frame 6 from the bottom end of the U-shaped magnet 4. At this time, the module frame 6 moves upward, and the left and right ends of the U-shaped magnet 4 apply force to the guide ball 129. At this time, the two guide balls 129 are then subjected to the thrust, that is, the two guide balls 129 are driven to move relatively away from each other. At this time, the limit spring 10 can be compressed, and the two lateral guide blocks 127 are relatively away from each other, and at the same time, the two connecting rods 1210 at the bottom are driven to move in a direction away from each other. The module frame 6 is deflected and an upward thrust is applied to the movable frame 121 at the bottom until the module frame 6 is completely engaged with the U-shaped magnet 4. At this time, the guide ball 129 moves to the top and is no longer subjected to the force from the U-shaped magnet 4. The limit spring 10 automatically resets and drives the two guide balls 129 to be relatively close until the guide balls 129 are completely located above the module frame 6. The modular installation process is completed. At this time, the two U-shaped magnets 4 are restricted by the module frame 6 and cannot be separated. The locking process is completed.

[0046] By utilizing the cooperation between the card slot 5 and the module frame 6 in the traditional magnetic installation method, and by the cooperation between the module frame 6 and the anti-theft component 12, the device can quickly complete the modular installation. At the same time, after the installation is completed, the two U-shaped magnets 4 cannot be separated, the anti-theft opening is completed, and it cannot be unlocked by normal means. The modular installation allows the shoulder bag to activate the anti-theft function only when needed, which will not affect normal use and improve practicality.

[0047] like Figure 3 and Figure 6 as well as Figure 9 As shown, when the limit spring 10 is in the initial state, the distance between the two guide balls 129 is at the minimum value, and the longitudinal guide block 124 is at the lowest point. At this time, the distance between the two guide balls 129 is smaller than the width of the U-shaped magnet 4. When the module frame 6 and the U-shaped magnet 4 are fully installed, the limit spring 10 is in the initial state, and the two limit frames 128 are both located at the top position between the two U-shaped magnets 4.

[0048] Embodiment: When unlocking is required, the push rod 122 can be pressed upward to move the movable frame 121 and the longitudinal guide block 124 upward. At this time, the first fixed seat 125 is moved upward accordingly, and drives the two connecting rods 1210 to deflect in the direction away from each other, and applies pulling force to the two lateral guide blocks 127 at the top. At this time, the two lateral guide blocks 127 are relatively away from each other, and drive the two guide balls 129 to move away from each other, releasing the limiting process on the top of the U-shaped magnet 4. At this time, the guide balls 129 no longer limit the U-shaped magnet 4. After maintaining the current state, the module frame 6 is pulled out downward until the module frame 6 is completely separated from the U-shaped magnet 4, and the unlocking process is completed.

[0049] By utilizing simple upward and downward pulling movements and utilizing the cooperation between the anti-theft component 12, the module frame 6, and the U-shaped magnet 4, the device can quickly complete unlocking. The entire unlocking process does not require the use of complex unlocking methods such as keys required by traditional devices. At the same time, it can prevent the shoulder bag from being opened by criminals, achieve anti-theft while simplifying the opening method, and improve safety and convenience.

[0050] By reusing the unlocking process, that is, after the shoulder bag is unlocked, the module frame 6 and the U-shaped magnet 4 can be separated. At this time, the shoulder bag is in a normal state and can be opened and closed normally by adsorption through the U-shaped magnet 4. After disassembly, the module frame 6 can be put into the inside of the U-shaped magnet 4 and used as a normal shoulder bag. No complicated anti-theft structure is set on the shoulder bag, so that the shoulder bag can be switched between the anti-theft state and the normal state, further improving its applicable scenarios.

[0051] A method for using a modular intelligent anti-theft shoulder bag comprises the following steps:

[0052] S1: When anti-theft is required, the bag cover 2 needs to be closed to keep the two U-shaped magnets 4 in an adsorbed state, and at this time, the module frame 6 is pushed in from the bottom to complete the engagement between the card block 7 and the card slot 5. When the module frame 6 is pushed upward, the guide ball 129 is then acted upon by the module frame 6, and the two guide balls 129 are then relatively separated;

[0053] S2: At this time, the limit spring 10 can be compressed and drive the two lateral guide blocks 127 to move away from each other until the two connecting rods 1210 deflect in the direction away from each other and exert a pulling force on the movable frame 121, and the movable frame 121 rises accordingly until the module frame 6 and the U-shaped magnet 4 are completely installed, and the guide ball 129 is no longer subjected to the lateral thrust of the module frame 6;

[0054] S3: The limit spring 10 automatically resets, and at the same time drives the two guide balls 129 to approach each other, so that the module frame 6 and the anti-theft component 12 are connected and the fixing process is completed. At this time, the module frame 6 prevents the two U-shaped magnets 4 from separating from each other, and the anti-theft process is completed;

[0055] S4: When unlocking, by pushing the push rod 122 upward, the movable frame 121 is driven to move upward. At this time, the limit spring 10 is compressed and drives the two guide balls 129 to move away from each other. After the limit process between the U-shaped magnet 4 is released, the module frame 6 is pulled out downward to release the clamping connection between the module frame 6 and the U-shaped magnet 4, and the unlocking is completed.

[0056] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

The usage method of a modular intelligent anti-theft single-shoulder bag according to claim 8, characterized in that: The following steps are involved: S1: When anti-theft is required, the bag cover (2) needs to be closed to keep the two U-shaped magnets (4) in an adsorbed state, and at this time, the module frame (6) is pushed in from the bottom, so that the card block (7) and the card slot (5) are connected, and when the module frame (6) is pushed upward, the guide ball (129) is then subjected to the force of the module frame (6), and the two guide balls (129) are relatively separated; S2: At this time, the limit spring (10) can be compressed and drive the two lateral guide blocks (127) to move away from each other until the two connecting rods (1210) deflect in the direction away from each other and exert a pulling force on the movable frame (121), and the movable frame (121) rises accordingly until the module frame (6) and the U-shaped magnet (4) are completely installed, and the guide ball (129) is no longer subjected to the lateral thrust of the module frame (6); S3: The limit spring (10) automatically resets, and at the same time drives the two guide balls (129) to approach each other, thereby completing the clamping connection between the module frame (6) and the anti-theft component (12), and completing the fixing process. At this time, the module frame (6) prevents the two U-shaped magnets (4) from separating from each other, and the anti-theft process is completed; S4: When unlocking, the push rod (122) is pushed upward to drive the movable frame (121) to move upward. At this time, the limit spring (10) is compressed and drives the two guide balls (129) to move away from each other. After the limit process between the U-shaped magnet (4) is released, the module frame (6) can be pulled out downward to release the clamping connection between the module frame (6) and the U-shaped magnet (4), thereby completing the unlocking.
