Description

Technical Field

[0001] This utility model belongs to the field of lock and buckle technology, specifically relating to a lock and buckle and a bag. Background Technology

[0002] From a practical standpoint, clasps primarily function to open and close bag openings, ensuring the safety of items inside. The market offers a wide variety of clasps with diverse structures, including rotating, push-lock, and nowadays, single magnetic clasps. In terms of aesthetics, different clasps complement different bag designs, enhancing the product's visual appeal. However, existing clasps have the following shortcomings: Magnetic clasps rely solely on the magnet's locking function, making them easily opened and insufficiently effective at preventing theft; push-lock clasps sometimes feel too tight, making them inconvenient to use and causing hand pain after prolonged use; and conventional non-magnetic clasps leave the bag opening completely open when not engaged, offering no anti-theft function, and requiring two separate operations to close the clasp after opening. To address at least one of these technical problems, it is necessary to develop a new type of clasp and bag design. Utility Model Content

[0003] The purpose of this utility model is to provide a lock and bag to solve the aforementioned technical problems. By rotating a mechanism and moving its end to a position that interferes with the movement of the buckle body, the buckle body is limited, thus maintaining it in a locked state. When unlocking is required, the rotating mechanism rotates to a state that does not interfere with the movement of the buckle body. This operation method is simple, can be operated with one hand, and has a large operable rotation range, avoiding the inconvenience of pressing to control the locking or unlocking state in existing technologies. Simultaneously, the rotation paths are perpendicular, making the rotation plane of the rotating mechanism parallel to the plane of the connecting body and the buckle body, thus requiring less space in the vertical direction relative to the connecting body, facilitating operation. An elastic mechanism keeps the rotating block tightly against the connecting body, increasing the friction between them, thereby making it easier to maintain the position after the rotating block has rotated to the desired location.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A latch includes a connecting body and a latch body that can be engaged with the connecting body. The connecting body is movably connected to a rotating mechanism. The rotation path of the rotating mechanism is perpendicular to the movement path of the latch body that allows it to disengage from the connecting body. The rotating mechanism can be adjusted to restrict the latch body from disengaging from the connecting body. By rotating the rotating mechanism and moving its end to a position that interferes with the movement of the latch body, the latch body is limited, thus maintaining a locked state. When unlocking is required, the rotating mechanism is rotated to a state that does not interfere with the movement of the latch body. This operation method is simple, can be operated with one hand, and has a large operable rotation range, avoiding the problem of inconvenience caused by pressing to control the locked or unlocked state in existing technologies. At the same time, the rotation paths are perpendicular to each other, making the rotation plane of the rotating mechanism parallel to the plane of the connecting body and the latch body, thus requiring less space in the vertical direction relative to the connecting body, thereby facilitating operation.

[0006] Preferably, the connecting body is provided with a first through hole, and the rotating mechanism includes a rotating shaft rotatably connected to the first through hole and a rotating block disposed on the rotating shaft to restrict the release of the buckle. The rotating shaft can slide axially to move the rotating block, and the rotating shaft is also provided with an elastic mechanism. The elastic force of the elastic mechanism causes the rotating block to fit tightly against the connecting body. The first through hole is a circular hole. The extension direction of the rotating block is perpendicular to the axial direction of the rotating shaft. The rotating block rotates around the rotating shaft as its rotation center. The rotation of the rotating block is achieved through the movable connection of the first through hole, allowing the end of the rotating block away from the rotation center to rotate to a position that interferes with the movement of the buckle or does not interfere with the movement of the buckle, thus achieving a locked or unlocked state. This operation method is simple, and the rotating block with a certain extension stroke allows for a large operable rotational position, avoiding the problem of inconvenient operation caused by pressing to control the locked or unlocked state in the prior art. Simultaneously, the rotation paths are perpendicular to each other, making the rotation plane of the rotating block parallel to the plane of the connecting body and the buckle, thus requiring less space in the vertical direction relative to the connecting body, thereby facilitating operation. The function of the elastic mechanism is to prevent the rotating block from becoming unstable in long-term use when the shaft and hole are only fitted together, as the gap at the joint may increase. The elastic mechanism keeps the rotating block in close contact with the connecting body, increasing the friction between them, and thus making it easier to maintain the position after the rotating block has rotated to the required position.

[0007] Preferably, the connecting body is further provided with a limiting structure to limit the rotation of the block. The limiting structure allows the rotating block to maintain its position after rotation, such as a position that interferes with the movement path of the buckle, thereby maintaining the stability of the locked state; or a position that does not interfere with the movement path of the buckle, thereby maintaining the state of the rotating block being unlocked from the buckle.

[0008] Preferably, the limiting structure includes a locking point and a slot that engages with the locking point, wherein multiple slots are circumferentially distributed around the axis of the rotation shaft so that the locking point can switch between slots; one of the locking point and the slot is disposed on the rotating block and the other is disposed on the connecting body. Along the axial projection direction of the rotation axis, the rotation path of the locking point furthest from the center of the rotation axis falls into the circle formed by the line connecting the position of the locking slot and the center of the first through hole as the radius. This allows the interlocking locking points and slots to restrict the rotation of the rotating block, thereby maintaining the rotating block in a non-rotating state when locking the buckle, thus improving the stability of the locked state. When the rotating block unlocks the buckle, the interlocking action of the locking points and slots prevents the rotating block from spontaneously rotating to the position where it locks the buckle, thus maintaining the unlocked state. Simultaneously, when the locking points and slots are set corresponding to the position where the rotating block locks the buckle, the user can operate without observing the rotating block. The user also receives feedback during operation when the slot and locking point are interlocked, thus improving operational convenience.

[0009] Preferably, the locking points are located on the rotating block, and there may be one locking point or multiple locking points arranged around the axis of rotation. The locking points are arranged at equal or unequal intervals around the axis of rotation. In this technical solution, four locking points are arranged at equal intervals. The line connecting every two locking points to the center of the rotating axis corresponds to a 90-degree rotation angle on the surface of the rotating axis. The multiple locking points allow for multiple engagement positions under the influence of the rotating axis, facilitating the locking or unlocking of the rotating block onto the buckle.

[0010] Preferably, the slots are disposed on the connecting body, and all slots communicate with the first through hole. One slot may be provided, or multiple slots may be arranged around the first through hole as the center. In this technical solution, four slots are arranged at equal or unequal intervals around the first through hole. The line connecting every two slots to the center of the first through hole corresponds to a 90-degree rotation angle on the rotating shaft surface. This corresponds to one locking position and three unlocking positions. The slot at the locking position falls on the centerline projection of the rotating block when locking the buckle. With multiple slots, the locking point has multiple engaging positions under the drive of the rotating shaft, facilitating the locking or unlocking of the rotating block on the buckle.

[0011] Preferably, the locking point is tapered towards the bottom of the slot to form a guide surface that guides the locking point and the slot to disengage. This tapering design forms a guide surface; when an external force is applied to the rotating block, causing it to rotate, the guide surface helps the rotating block overcome the elastic force of the elastic mechanism, moving it away from the connecting body and thus separating the locking point from the slot. As the rotating block continues to rotate, when the locking point moves to another slot, it is embedded in that slot under the elastic force of the elastic mechanism, forming a positioning point.

[0012] Preferably, the cross-section of the locking point is one of a sector, a square, or a trapezoid. In this technical solution, the cross-section of the locking point is sector-shaped; the shape of the locking point only needs to satisfy the requirement of fitting into the locking slot.

[0013] Preferably, the cross-section of the slot is one of a fan shape, a square shape, or a trapezoidal shape. The cross-sectional shape of the slot matches the cross-sectional shape of the locking point; in this technical solution, the cross-sectional shape of the slot is fan-shaped. The shape of the slot only needs to be able to fit snugly into the locking point.

[0014] Preferably, the elastic mechanism includes a spring with one end abutting against the inner surface of the connecting body along the axial direction of the rotation axis, and the other end of the spring in the axial direction connected to the end of the rotation axis away from the first through hole. Specifically, one end of the spring abuts against the inner surface of the connecting body near the location of the first through hole, corresponding to a contact surface, which is located between the outer diameter of the first through hole and the inner diameter of the first through groove; wherein the contact position is located at the outer edge of the first through hole; the rotating shaft is connected to the spring by striking it with its end; so that in the initial state, the rotating shaft, under the elastic force of the spring, keeps the locking point falling into the slot or the locking point having a force toward the slot, thereby keeping the rotating block in the locked or unlocked position after rotation; at the same time, under the action of the spring, when the locking point and the slot are set in a position corresponding to the locking position of the rotating block on the fastener, the user can operate without observing the rotating block, and the user has feedback on the engagement process when the slot and the locking point are engaged during operation, thereby improving the convenience of operation.

[0015] Preferably, the connecting body further comprises a first through groove that is coaxially connected to and communicates with the first through hole, wherein the inner diameter of the first through groove is larger than the inner diameter of the first through hole.

[0016] The rotating shaft, spring, and first through slot are arranged coaxially from the inside out. The first through slot is provided to facilitate support on the radial side of the spring, thus preventing any impact on the stability of the spring during operation.

[0017] Preferably, a first contact block is coaxially disposed at one end of the rotating shaft near the rotating block, and the upper end of the locking point along the axial direction of the rotating shaft abuts against the first contact block.

[0018] Projected along the axial direction of the rotation axis, the outer diameter of the first bonding block is greater than the distance between the end of the locking point and the center of the rotation axis, and the outer diameter of the first bonding block is greater than the diameter of the first through hole;

[0019] The first bonding block is abutted against the upper surface of the connector. Specifically, the first bonding block is abutted against the outer periphery of the connector where the first through hole is located. The abutting of the first bonding block against the upper surface of the connector prevents the locking point from moving below the slot, thus preventing the locking point and the slot from maintaining a mutually engaged state.

[0020] Preferably, the connector is provided with a first frame to accommodate the buckle;

[0021] Along the axial direction of the rotation axis, the first frame is positioned below the rotating surface of the rotating block. This ensures that when the buckle is in the limited position, it is positioned between the rotating block and the connecting body; the overall volume is relatively small.

[0022] Preferably, the buckle body is provided with a first fitting groove; the first frame body is provided with a first fitting block that can fit into the first fitting groove. When the buckle body is connected to the connecting body, the first fitting groove and the first fitting block are in a mutually fitted state, preventing the buckle body in the locked state from disengaging from the connecting body in the radial direction of the rotation axis. Together with the rotating block, the buckle body is limited, so that the buckle body in the locked state is limited in both the axial and radial planes, improving the connection stability. When unlocking, the rotating block is rotated to avoid interfering with the movement path of the buckle body in the axial direction, thereby allowing the buckle body to disengage in the axial direction and unlock.

[0023] Preferably, along the axial projection of the rotation axis, one or more first magnetic suction parts are provided inside the connector at the outer periphery of the first fitting block location;

[0024] Inside the buckle body, one or more second magnetic attracting parts are provided on the outer periphery of the first fitting groove, which can magnetically attract the first magnetic attracting part to position the first fitting groove and the first fitting block. The number of first magnetic attracting parts corresponds to the number of second magnetic attracting parts. Projected axially along the rotation axis, the first magnetic attracting parts are symmetrically arranged on both sides of the first fitting block; the second magnetic attracting parts are symmetrically arranged on both sides of the first fitting groove.

[0025] Specifically, both the first and second magnetic attraction parts are magnets. By providing these two magnetic attraction parts, when the buckle body moves to the first frame, the first and second magnetic attraction parts attract each other. Since the first and second magnetic attraction parts are respectively located on both sides of the axial projection of the first fitting block and on both sides of the axial projection of the first fitting groove, the magnetic attraction keeps the first fitting block and the first fitting groove mutually engaged. Even when the buckle body is not restricted by the rotating block, the first fitting block and the first fitting groove remain mutually engaged under the magnetic attraction of the first and second magnetic attraction parts. This design prevents the bag from being left open, thus providing anti-theft functionality. The double protection provided by the magnet and the interlocking of the first and second magnetic parts ensures the magnet won't slip. When the bag needs to be opened, force is applied to separate the first and second magnetic parts. When closing the bag, the magnet's attraction causes the buckle to automatically close when it comes close to the first frame. Furthermore, a rotating block locks the buckle, providing multiple layers of locking while it's magnetically attracted to both the first and second magnetic parts. This solves the problem of a single magnet's locking function being easily opened and having insufficient anti-theft effectiveness.

[0026] Preferably, the connector has a first mounting groove inside for mounting the first magnetic part. Adhesive is applied into the first mounting groove to fix the first magnetic part in place.

[0027] Preferably, the buckle body has a second mounting groove for mounting the second magnetic part. Adhesive is applied into the first mounting groove to fix the first magnetic part.

[0028] Preferably, the connector includes a base and a first gasket connected to each other to clamp the fabric, wherein a first through hole is provided on the base. A first through groove and a first mounting groove are both provided inside the base; a first frame is provided on one side of the base; a connecting hole is provided on the base, and a first fitting block is threadedly connected to a screw passing through the connecting hole, thereby fixing the first fitting block on the first frame; wherein the base is provided with a plurality of first screw holes, the first gasket is provided with a plurality of first eyelets, and the first screw is connected to the first screw holes through the first eyelets, thereby connecting the base and the first gasket, thereby clamping the fabric;

[0029] Preferably, the fastener includes a first connector and a second washer connected to each other to clamp the fabric. A second mounting groove is provided on the plane of the first connector facing the second washer, and on the side of the washer facing the first connector. Both the fabric and the second washer have through holes communicating with the first fitting groove, facilitating the first fitting block to fit into the first fitting groove through the through holes. The through holes are the same size as the first fitting groove and have a certain fitting depth, improving connection stability. When the connector and the fastener are connected, the bottom of the second washer is in contact with the upper plane of the first frame. The first connector has multiple second screw holes, and the second washer has multiple second eyelets. Second screws connect to the second screw holes through the second eyelets, thereby connecting the first connector and the second washer to clamp the fabric.

[0030] Preferably, with the direction from the first connector to the second gasket as the axial direction, a baffle extending toward the direction in which the second gasket is disposed is provided on one side of the first connector;

[0031] The radial side of the baffle is positioned opposite to the radial side of the second gasket. This protects the fabric from rubbing against the connector or from being scraped by external objects when the fabric is disconnected from the connector.

[0032] A bag or luggage bag, provided with the aforementioned clasp.

[0033] This application has achieved beneficial technical effects:

[0034] This invention uses a rotating mechanism to rotate and move its end to a position that interferes with the movement of the buckle, thus limiting the buckle's movement and maintaining it in a locked state. When unlocking is needed, the rotating mechanism rotates to a state that does not interfere with the buckle's movement. This operation is simple, can be operated with one hand, and allows for a large range of rotation, avoiding the inconvenience of pressing to control the locking or unlocking state in existing technologies. Simultaneously, the rotation paths are perpendicular, making the rotation plane of the rotating mechanism parallel to the plane of the connecting body and the buckle, thus requiring less space in the vertical direction relative to the connecting body, facilitating operation. An elastic mechanism keeps the rotating block tightly against the connecting body, increasing friction between them, making it easier to maintain the position after the rotating block has rotated to the desired location.

Detailed Implementation

[0053] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0054] The technical solution of this utility model will be described in detail below with specific embodiments.

[0055] Reference Figures 1 to 16 As shown, a latch includes a connecting body 1 and a latch 2 that can be engaged with the connecting body 1. The connecting body 1 is movably connected to a rotating mechanism 3. The rotation path of the rotating mechanism 3 is perpendicular to the movement path of the latch 2 that allows it to disengage from the connecting body 1. The rotating mechanism 3 can be adjusted to restrict the latch 2 from disengaging from the connecting body 1. By rotating the rotating mechanism 3 and moving its end to a position that interferes with the movement of the latch 2, the latch 2 is limited, thus maintaining the latch 2 in a locked state. When unlocking is required, the rotating mechanism 3 is rotated to a state that does not interfere with the movement of the latch 2. This operation method is simple, can be operated with one hand, and has a large operable rotation range, avoiding the problem of needing to press to control the locked or unlocked state in the prior art, which is inconvenient to operate. At the same time, the rotation paths are perpendicular to each other, making the rotation plane of the rotating mechanism 3 parallel to the plane where the connecting body 1 and the latch 2 are located, thus requiring less space in the vertical direction relative to the connecting body 1, thereby facilitating operation.

[0056] The connecting body 1 is provided with a first through hole 11. The rotating mechanism 3 includes a rotating shaft 32 rotatably connected to the first through hole 11 and a rotating block 31 disposed on the rotating shaft 32 to restrict the buckle 2 from disengaging. The rotating shaft 32 can slide axially to drive the rotating block 31 to move. The rotating shaft 32 is also provided with an elastic mechanism. The elastic force of the elastic mechanism makes the rotating block 31 fit tightly against the connecting body 1. The first through hole 11 is a circular hole. The extension direction of the rotating block 31 is perpendicular to the axial direction of the rotating shaft 32. The rotating block 31 rotates around the rotating shaft 32 as the rotation center. The rotation of the rotating block 31 is realized through the movable connection of the first through hole 11, so that the end of the rotating block 31 away from the rotation center rotates to a position that interferes with the movement of the buckle 2 or a position that does not interfere with the movement of the buckle 2, realizing the locking or unlocking state. This operation method is simple, and the rotating block 31 with a certain extension stroke is provided, so that the operable rotation position is large, avoiding the problem of the prior art that requires pressing to control the locking or unlocking state, which is inconvenient to operate. Meanwhile, the rotation paths are perpendicular to each other, making the rotation plane of the rotating block 31 parallel to the planes of the connecting body 1 and the fastener 2. This reduces the space required in the vertical direction relative to the connecting body 1, thus facilitating operation. The function of the elastic mechanism is to prevent the rotating block 31 from becoming unstable due to increased gaps at the rotational fit point caused by relying solely on the fit between the shaft and the hole during long-term use. The elastic mechanism keeps the rotating block 31 in close contact with the connecting body, increasing the friction between them, thus making it easier to maintain the position of the rotating block 31 after it has rotated to the required position.

[0057] The connecting body 1 is also provided with a limiting structure to limit the rotation block 31. The limiting structure allows the rotation block to maintain its position after rotation, such as a position that interferes with the movement path of the buckle 2, thereby maintaining the stability of the locked state, or a position that does not interfere with the movement path of the buckle 2, thereby maintaining the state of the rotation block 31 unlocked from the buckle 2.

[0058] The limiting structure includes a locking point 41 and a locking groove 42 that fits into the locking point 41. Multiple locking grooves 42 are circumferentially distributed around the axis of the rotating shaft 32 so that the locking point 41 can switch between each locking groove 42. One of the locking point 41 and the locking groove 42 is provided on the rotating block 31, and the other is provided on the connecting body 1. Along the axial projection direction of the rotation axis 32, the rotation path of the locking point 41, which is furthest from the center of the rotation axis 32, falls into the annulus formed by the line connecting the position of the slot 42 and the center of the first through hole 11 as the radius. The interlocking locking point 41 and slot 42 can restrict the rotation of the rotating block 31, thereby keeping the rotating block 31 in a non-rotating state when locking the buckle 2, thus improving the stability of the locked state. When the rotating block 31 unlocks the buckle 2, the interlocking action of the locking point 41 and slot 42 prevents the rotating block 31 from spontaneously rotating to the position where it locks the buckle 2, thus maintaining the unlocked state. At the same time, when the locking point 41 and slot 42 are set corresponding to the position where the rotating block 31 locks the buckle 2, the user can operate without observing the rotating block. The user also receives feedback on the interlocking process when the slot 42 is interlocked with the locking point 41 during operation, thereby improving the convenience of operation.

[0059] The locking point 41 is disposed on the rotating block 31. One locking point 41 may be provided, or multiple locking points 41 may be arranged around the axis of the rotating shaft 32. Multiple locking points 41 may be arranged at equal or unequal intervals around the axis of the rotating shaft 32. The locking points 41 can be directly fixed to the lower end face of the rotating block 31. Alternatively, the locking points 41 can be fixed to the outer peripheral wall of the rotating shaft 32, indirectly disposed on the rotating block 31 through the rotating shaft 32. Specifically, in this technical solution, four locking points 41 are arranged at equal intervals. The line connecting every two locking points 41 to the center of the rotating shaft 32 corresponds to a 90-degree rotation angle on the surface of the rotating shaft 32. By providing multiple locking points 41, under the drive of the rotating shaft 32, the locking points 41 have multiple engaging positions, thus facilitating the locking or unlocking of the rotating block 31 onto the buckle 2.

[0060] The slot 42 is disposed on the connecting body 1, and all slots 42 communicate with the first through hole 11. One slot 42 may be provided, or multiple slots 42 may be arranged around the first through hole 11 as the center. Multiple slots 42 may be arranged at equal or unequal intervals around the first through hole 11. In this technical solution, four slots 42 are arranged at equal intervals. The line connecting every two slots 42 to the center of the first through hole 11 corresponds to a 90-degree rotation angle on the surface of the rotation axis 32. This corresponds to one locking position and three unlocking positions. For example... Figure 16As shown, the rotating block 31 rotates to the unlocked position, and the angle α between this position and the locking position of the buckle is 90 degrees. The slot 42 provided in the locking position falls on the centerline projection of the rotating block 31 when the buckle is locked. Multiple slots 42 are provided, so that the locking point 41 has multiple positions that can be engaged under the drive of the rotating shaft, thereby facilitating the locking or unlocking of the buckle 2 by the rotating block 31.

[0061] The locking point 41 is tapered towards the bottom of the slot 42 to form a guide surface that guides the locking point 41 and the slot 42 to disengage. This tapering design forms a guide surface. When an external force is applied to the rotating block 31, causing it to rotate, the guide surface helps the rotating block overcome the elastic force of the elastic mechanism, allowing it to move away from the connecting body 1 and thus disengage the locking point 41 from the slot 42. As the rotating block 31 continues to rotate, the locking point 41 moves to another slot 42, where it is embedded in the slot 42 under the elastic force of the elastic mechanism, forming a positioning point.

[0062] Preferably, the cross-section of the locking point 41 is one of a fan shape, a square shape, or a trapezoidal shape. In this technical solution, the cross-section of the locking point 41 is fan-shaped; wherein the shape of the locking point is sufficient to fit into the locking slot.

[0063] Preferably, the cross-section of the slot 42 is one of a fan shape, a square shape, or a trapezoidal shape. The cross-sectional shape of the slot 42 is adapted to the cross-sectional shape of the locking point 41; in this technical solution, the cross-sectional shape of the slot 42 is fan-shaped. The shape of the slot 42 only needs to be able to fit into the locking point.

[0064] The elastic mechanism includes a spring 5, one end of which abuts against the inner surface of the connecting body along the axial direction of the rotating shaft 32. The other end of the spring 5 along the axial direction is connected to the end of the rotating shaft 32 away from the first through hole 11. Specifically, the end of the rotating shaft 32 away from the first through hole 11 is riveted outwards to form a limiting part, thereby connecting the spring 5. One end of the spring 5 abuts against the inner surface of the connecting body 1 near the location of the first through hole 11, corresponding to a contact surface 10. This contact surface 10 is located between the outer diameter of the first through hole 11 and the inner diameter of the first through groove 111; the contact position is located at the outer edge of the first through hole 11. The rotating shaft 32 is connected to the spring 5 by striking the end of the rotating shaft 32, so that the rotating shaft 32, in its initial state, is held in place by the elastic force of the spring 5. When the holding point 41 falls into the card slot 42 or the holding point 41 has a force toward the card slot 42, it keeps the rotating block 31 in the locked or unlocked position of the buckle 2 after rotation. At the same time, under the action of the spring 5, when the holding point 41 and the card slot 42 are set in the corresponding position of the rotating block 31 locking the buckle 2, the user can operate without observing the rotating block 31. The user can also receive feedback on the engagement process when the card slot 42 and the holding point 42 are engaged during operation, thereby improving the convenience of operation.

[0065] The connecting body 1 is further provided with a first through groove 111 that is coaxially connected to and communicates with the first through hole 11. The inner diameter of the first through groove 111 is larger than the inner diameter of the first through hole 11.

[0066] The rotating shaft 32, spring 5, and first through groove 111 are arranged coaxially from the inside out. The first through groove 111 is provided to facilitate support of the radial side of spring 5 and avoid affecting the stability of spring 5 during operation.

[0067] The first fitting block 321 is coaxially disposed at one end of the rotating shaft 32 near the rotating block 31, and the upper end of the locking point 41 along the axial direction of the rotating shaft 32 abuts against the first fitting block 321.

[0068] Projected along the axial direction of the rotation axis 32, the outer diameter of the first bonding block 321 is greater than the distance between the end of the locking point 41 and the center of the rotation axis 32, and the outer diameter of the first bonding block 321 is greater than the diameter of the first through hole 11.

[0069] The first fitting block 321 is fitted to the upper surface of the connector 1. Specifically, the first fitting block 321 is fitted to the outer periphery of the connector 1 where the first through hole 11 is located. The first fitting block 321 is fitted to the upper surface of the connector 1 to prevent the locking point 41 from moving below the locking groove 42, thus preventing the locking point 41 and the locking groove 42 from maintaining a mutually engaged state.

[0070] The connector 1 is provided with a first frame 12 to accommodate the buckle 2;

[0071] Along the axial direction of the rotation axis 32, the first frame 12 is positioned below the rotating surface of the rotating block 31. This ensures that when the buckle 2 is in the limited position, it is positioned between the rotating block 31 and the connecting body; the overall volume is relatively small.

[0072] The buckle 2 is provided with a first fitting groove 21; the first frame 12 is provided with a first fitting block 13 that can fit into the first fitting groove 21. When the buckle 2 is connected to the connecting body 1, the first fitting groove 21 and the first fitting block 13 are in a mutually fitted state, preventing the buckle 2 in the locked state from coming out of the connecting body 1 radially from the rotating shaft 32, thus limiting the movement and release path of the buckle 2 to the axial direction. Together with the rotating block 31, the buckle 2 is limited, so that the buckle 2 in the locked state is limited in both the axial and radial planes, improving the connection stability. When unlocking, the rotating block 31 is rotated to avoid interfering with the movement path of the buckle 2 in the axial direction, thereby allowing the buckle 2 to come out in the axial direction and unlock.

[0073] Projected along the axial direction of the rotation axis 32, one or more first magnetic suction parts 14 are provided on the outer periphery of the first fitting block 13 inside the connecting body 1;

[0074] Inside the buckle body 2, one or more second magnetic suction parts 22 are provided on the outer periphery of the first fitting groove 21, which can magnetically attract the first magnetic suction part 14 to position the first fitting groove 21 and the first fitting block 13. The number of first magnetic suction parts 14 corresponds to the number of second magnetic suction parts 22. Projected axially along the rotation axis 32, the first magnetic suction parts 14 are symmetrically arranged on both sides of the first fitting block 13; the second magnetic suction parts 22 are symmetrically arranged on both sides of the first fitting groove 21.

[0075] Specifically, both the first magnetic attraction part 14 and the second magnetic attraction part 22 are magnets. By providing the first magnetic attraction part 14 and the second magnetic attraction part 22, when the buckle 2 moves to the first frame 12, the first magnetic attraction part 14 and the second magnetic attraction part 22 are magnetically attracted to each other. Since the first magnetic attraction part 14 and the second magnetic attraction part 22 are respectively located on both sides of the axial projection of the first fitting block 13 and on both sides of the axial projection of the first fitting groove 21, the first fitting block 13 and the first fitting groove 21 can be kept mutually engaged by magnetic attraction. This ensures that the buckle 2 is not limited by the rotating block 31, and the first fitting block 13 and the first fitting groove 21 are magnetically attracted by the first magnetic attraction part 14 and the second magnetic attraction part 22. Under the action of the magnet, the two parts are kept in a mutually interlocking state, thus preventing the bag from being left open and providing anti-theft function. With the double protection of the magnet and the first interlocking block and the first interlocking groove, the magnet can be prevented from sliding sideways. When the bag needs to be opened, force is applied to separate the first magnetic part 14 and the second magnetic part 22. When the bag is closed, the attraction of the magnet will automatically close the buckle 3 when it comes close to the first frame 12. In addition, a rotating block 31 is set to lock the buckle 2. In the state of being magnetically attracted with the first magnetic part 14 and the second magnetic part 22, the buckle 2 is locked in multiple ways, which solves the problem that the buckle function of a single magnet is easy to open the bag and the anti-theft effect is not good.

[0076] The connector 1 has a first mounting groove 15 inside for mounting the first magnetic part 14. Glue is applied into the first mounting groove to fix the first magnetic part.

[0077] The buckle body 2 has a second mounting groove 23 for mounting the second magnetic part 22. Adhesive is applied to the first mounting groove to fix the first magnetic part.

[0078] The connector 1 includes a base 16 and a first gasket 17 connected to each other to clamp the fabric. A first through hole 11 is provided on the base 16. A first through groove 111 and a first mounting groove 15 are both provided inside the base 16. A first frame 12 is provided on one side of the base 16. A connecting hole 160 is provided on the base 16. A first fitting block 13 is threadedly connected to a screw passing through the connecting hole 160, thereby fixing the first fitting block 13 on the first frame 12. The base 16 is provided with a plurality of first screw holes 161, and the first gasket 17 is provided with a plurality of first eyelets 171. A first screw 172 is connected to the first screw holes 161 through the first eyelets 171, thereby connecting the base 16 and the first gasket 17 to clamp the fabric 6.

[0079] The fastener 2 includes a first connector 24 and a second gasket 25 that are connected to each other to clamp the fabric. A first fitting groove 21 is provided on the plane of the first connector 24 facing the second gasket 25, and a second mounting groove 23 is provided on the side of the second gasket 25 facing the first connector 24. Both the fabric and the second gasket 25 have through holes 26 that communicate with the first fitting groove 21, facilitating the first fitting block 13 to fit into the first fitting groove 21 through the through holes 26. The through holes 26 have the same size as the first fitting groove 21 and a certain fitting depth, improving connection stability. When the connector 1 and the fastener 2 are connected, the bottom of the second gasket 25 is in contact with the upper plane of the first frame 12. The first connector 24 is provided with a plurality of second screw holes 241, the second washer 25 is provided with a plurality of second holes 251, and the second screw 252 is connected to the second screw holes 241 through the second holes 251, thereby connecting the first connector 24 and the second washer 25 to clamp the fabric 6.

[0080] With the direction from the first connector 24 to the second gasket 25 as the axial direction, a baffle 27 extending toward the second gasket 25 is provided on one side of the first connector 24;

[0081] The radial side of the baffle 27 is positioned opposite to the radial side of the second gasket 25. This protects the fabric from rubbing against the connector 1 on its radial side or from being rubbed by external objects when the fabric is disconnected from the connector 1.

[0082] A bag or luggage bag, provided with the aforementioned clasp.

[0083] This technical solution combines magnets and latches, locking and unlocking the latch by rotating the rotating block, and combining it with the magnetic attraction function for better opening and closing, thus playing a role in theft prevention; it realizes the multi-functional use of the product and meets various usage scenarios in people's daily lives.

[0084] Rotate the block, and it will open the assembled connector at a 90-degree angle. The rotation direction can be either left or right. Place the buckle near the top of the first frame and use the attraction between the positive and negative magnets to find the right position. The first fitting slot and the first fitting block will then fit together securely. Finally, rotate the block back to the top of the buckle. This completes the opening and closing process.

[0085] The rotating shaft has four protruding locking points, each spaced exactly 90 degrees apart. The first through hole has four recessed points, or locking grooves, that correspond to these locking points. After assembly by striking the end of the rotating shaft against the spring, a rotating component is formed and fixed to the connector. In use, the spring's elasticity causes the locking points to rotate within a range of four points, each 90 degrees. To open or close, simply rotate the component 90 degrees.

[0086] Another innovation of this technical solution is the combination of magnets and a concave-convex interlocking structure. Due to the inclusion of a first magnetic attraction part and a second magnetic attraction part, the buckle and the connector can automatically attract each other during use. Furthermore, the first fitting groove and the first fitting block interlock with each other, which helps the magnet's attraction force to play an anti-slip role, equivalent to a locking point.

[0087] Compared to the original rotating lock, when the rotating block is opened, the clasp will not cause the bag flap to pop up due to the attraction of the magnet, providing an additional layer of security.

[0088] The magnet, along with the first fitting groove and the first fitting block, provides two double-layer protections to prevent the magnet from slipping. It can be opened when in use and automatically closed when the two parts are close together due to the attraction of the magnet when not in use.

[0089] The rotating block can be rotated to lock or unlock the buckle, and can be operated with one hand, which is simple and convenient.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
