Description

Technical Field

[0001] The utility model belongs to the technical field of buckles, and in particular relates to a buckle. Background Art

[0002] Buckles are locking components used on luggage, closures, clothing, and other items that require adjustment when opening or closing. Clothing such as jackets, hats, shoes, or backpacks all require buckling. This closure device is used to fasten two components together, such as suitcases, bags, clothing, shoes, or helmets.

[0003] In the prior art, a buckle connects two corresponding components and can be locked or unlocked as needed. However, when using a luggage buckle, for example, the existing buckle requires one hand to stabilize the bag and the other to open the buckle, making it impossible to unlock it with one hand, which is inconvenient. Furthermore, due to the lack of a corresponding alignment structure, the buckle in the prior art cannot achieve automatic alignment and fixation, requiring manual alignment and insertion, making the convenience of use need to be improved. In addition, during use, when the buckle of the luggage buckle touches other objects, there is the problem of accidental unlocking. After the accidental unlocking, the luggage will be in the open state, and there is a risk of items inside the luggage falling out. Therefore, it is necessary to develop a buckle. Utility Model Content

[0004] The object of the present utility model is to provide a buckle to solve the above-mentioned technical problems, wherein the moving part contacts the fastening part to control whether the fastening part moves, and when the moving part and the fastening part are in a non-interference state, the internal space of the fastening part limits the fastener, thereby completing the locked state; when the fastening part moves, its moving path is perpendicular to the moving direction of the moving part, and the moving part contacts and squeezes the fastening part, so that the fastening part is stretched and moved to complete the unlocked state; after completing the unlocked state, when the fastener needs to be locked again, the moving part is pressed again to put the fastening part in the unlocked state, and the fastener is inserted accordingly. After releasing the moving part, the fastening part returns to the state of limiting the fastener. The overall space required is small, and the implementation method of this operation is simple and easy to implement, and the user can operate it with one hand.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows:

[0006] A buckle comprises a shell, a buckle portion arranged in the shell, and a movable member for controlling whether the buckle portion moves or not, wherein the moving path extension direction of the movable member is perpendicular to the moving path extension direction of the buckle portion. The buckle portion is controlled to move by the movable member contacting the buckle portion, and when the movable member and the buckle portion are in a non-contacting state, the internal space of the buckle portion limits the buckle, thereby completing a locked state; when the buckle portion moves, its moving path is perpendicular to the moving direction of the movable member, and the movable member contacts and squeezes the buckle portion, so that the buckle portion is stretched and moved, completing an unlocked state; after completing the unlocked state and needing to re-lock the buckle, the movable member is pressed again to put the buckle portion in the unlocked state, and the buckle is correspondingly inserted. After releasing the movable member, the buckle portion returns to the state of limiting the buckle. The overall space required is small, and the implementation method of this operation is simple and easy to implement, and the user can operate it with one hand.

[0007] Preferably, the buckling portion includes an elastic portion having one end connected to the shell and a buckle body connected to an end of the elastic portion away from the shell. When the locking mechanism is in operation, the locking mechanism is in an initial state when the movable member is not under the force of the movable member, which is also a locked state. When unlocking is required, the movable member contacts the buckle body, causing the buckle body to overcome the elastic force of the elastic member and thus move in a direction perpendicular to the moving direction of the movable member. After the buckle body moves, the limited space inside the buckle body is away from the buckle, thereby completing the unlocking operation. The buckle parts are arranged in groups, and the two buckle bodies move in opposite directions, thereby increasing the space between the buckle bodies to the point where the buckle cannot be restricted from coming out by means of interference, thereby completing the unlocking operation. This unlocking method is simple and can be operated with one hand. When the locking operation is required, the movable member is pressed and the corresponding buckle is engaged, and then the pressing on the movable member is released. The buckle body is extended and stopped at the end by the elastic action of the elastic member. The buckle parts are arranged in groups, and the end faces of the two buckle bodies contact each other, forming a space inside the buckle body to limit the buckle, thereby preventing the buckle from coming out of the shell. This locking method is simple and can meet the requirements of single-handed operation.

[0008] Preferably, the buckle body includes a buckle body connected to the elastic part, and an abutment block provided on the buckle body and arranged opposite to the moving part;

The moving path of the extrusion block overlaps with the interference block in the initial state. One end of the buckle body is connected to the elastic part; the interference block is arranged on the buckle body and does not overlap with the end of the buckle body, so that there is a gap between the interference block and the end of the buckle body. The locking mechanism is simple and can be operated with one hand only. When the locking mechanism is in a state of being locked, the locking mechanism is unlocked and the latch is unlocked, so that the locking mechanism is unlocked and the latch is unlocked. When the locking mechanism is unlocked, the locking mechanism is unlocked and the latch is unlocked. When the locking mechanism is unlocked, the locking mechanism is unlocked and the latch is unlocked. When the locking mechanism is unlocked, the locking mechanism is unlocked and the latch is unlocked. When the locking mechanism is unlocked, the locking mechanism is unlocked and the latch is unlocked. When the locking mechanism is unlocked, the locking mechanism is unlocked and the latch is unlocked. When the locking mechanism is unlocked, the locking mechanism is unlocked and the latch is unlocked.

[0010] Preferably, the width of the extrusion block gradually increases from the end closest to the interference block to the end farther from the interference block. The end surface of the extrusion block gradually expands, causing the interference block to be gradually compressed and overcoming the force of the elastic portion to move to a certain distance. This increases the space between the buckle bodies to a state where the fastener cannot be restrained from being released by interference or to a state where the fastener is in a state before being inserted, thereby completing the buckle body movement operation before unlocking or locking. This unlocking and locking method is simple and can be completed with one hand.

[0011] Preferably, the friction block is provided with a first fitting surface on one side facing the extrusion block; the extrusion block is provided with second fitting surfaces on both sides perpendicular to its moving direction, and the first fitting surface and the second fitting surface are provided facing each other. A first fitting surface and a second fitting surface are provided that can fit together to complete the unlocking action, and in the unlocked state, the first fitting surface and the second fitting surface fit together; when the moving part is pressed, the second fitting surface moves toward the location where the first fitting surface is provided, and as the moving part is pressed and moved deeper into the shell, the second fitting surface fits with the first fitting surface and causes the first fitting surface to slide along the direction where the second fitting surface is provided, so that the buckle body overcomes the action of the spring and moves a certain distance, thereby increasing the space between the buckles to a state where the fastener cannot be restricted from being dislodged by means of friction or is in a state before the fastener to be locked is inserted, thereby completing the buckle body movement operation before unlocking or locking. This unlocking and locking method is simple and can be completed with one hand; the friction block is specifically provided on the arc surface of the buckle body.

[0012] Preferably, the buckle body is provided with a spacer surface between the abutment block and the end of the buckle body, and the extrusion block is provided with a third abutment surface at one end facing the spacer surface. The cross-sections of the spacer surface and the third abutment surface are both arc-shaped. When unlocked, the spacer surface and the third abutment surface abut each other. The fastening portion and the moving part are arranged in a group, wherein the width of the third fitting surface is set to be smaller than the maximum width of the line connecting the first fitting surfaces on the same side and larger than the width of the line connecting the ends of the spacing surfaces on the same side in the unlocked state, so that the third fitting surface can enter between the first fitting surfaces in the initial state, so that the second fitting surface performs a fitting and resistance operation on the first fitting surface, and at the same time, the third fitting surface performs a fitting and resistance operation on the spacing surface, thereby completing the unlocking operation or completing the operation before the fastener to be locked is inserted, the third fitting surface is fitted with the spacing surface, and the limit block and the resistance block are resisted, and multiple positions are resisted, while preventing the extrusion block from extending into the moving path of the buckle body, thereby improving the stability of the unlocked state and the state stability before the fastener to be locked is inserted; the maximum width of the second fitting surface corresponds to the space formed after the movement between the two buckle bodies for the fastener to pass through; the extrusion block is set to a length The length of the friction block is less than or equal to the length set along the moving direction of the moving part; a spacing surface is set so that there is a certain space under the friction block for the extrusion block to enter, and space is provided for the extrusion block to interfere and squeeze the friction block, and after the extrusion block moves to a certain distance, the third fitting surface conflicts with the spacing surface, so that the extrusion block will not extend into the moving path of the buckle body and affect the unlocking operation of the fastener or the operation of accommodating the fastener to be locked; when in the unlocked state, the third fitting surface conflicts with the spacing surface, thereby improving the stability of the unlocked state and facilitating one-handed operation. At the same time, the first fitting surface and the second fitting surface can be fit together by one-handed operation, so that a space for the fastener to enter is formed between the buckle bodies. After the fastener enters and releases the pressure on the moving part, the buckle bodies in groups move toward each other, thereby locking the fastener. This operation method can be operated with one hand.

[0013] Preferably, the housing includes a housing body and a through hole provided on the housing body for the moving member body to move, and the moving member body partially extends out of the housing through the through hole;

[0014] The moving member further includes a limit block provided on the moving member body and inside the housing, wherein the limit block is provided to abut against one end of the extrusion block;

[0015] Along the setting direction of the moving path of the moving part, the projection of the edge setting position of the through hole and the projection of the maximum stroke position of the interference block both fall within the projection range of the limit block.

[0016] On the one hand, it can prevent the entire moving part from escaping from the outside of the shell through the through hole. On the other hand, the limit block can interfere with the interference block when in the unlocked state or in the state before the fastener to be locked is inserted, thereby preventing the extrusion block from extending into the buckle body and affecting the insertion operation of the fastener. In the unlocked state, the limit block interferes with the end face of the interference block, and the third fitting surface fits with the spacing surface, thereby preventing the extrusion block from extending into the moving path of the buckle body and affecting the unlocking operation of the buckle body or the state before the fastener to be locked is inserted. The position where the limit block is set corresponds to the maximum width setting of the second fitting surface. The limit block is set to interfere with one end of the extrusion block away from the interference block. The main body of the moving part extends out of the shell through the through hole, which is convenient for the user to press the moving part to complete the unlocking operation or complete the operation before the fastener to be locked is inserted.

[0017] Preferably, the snap-fitting part and the movable part are arranged in groups, and the line connecting the installation positions of the snap-fitting part and the line connecting the installation positions of the movable part are perpendicular to each other. The through holes are arranged in groups accordingly. The snap-fitting part and the movable part arranged in groups, when in the unlocked state, the extrusion block squeezes the inner end faces of the two interference blocks on the same side, so that the two buckle bodies move in opposite directions, and the space formed between the two buckle bodies after movement is not enough to interfere with and limit the fastener, thereby completing the unlocking operation; when it is necessary to restore to the locked state again, press the movable part 3 and place the fastener between the two buckle bodies, and after the force on the movable part is released, the two buckle bodies move toward each other due to the force of the elastic part, so that the space between the two buckle bodies is gradually reduced, thereby interfering with and limiting the fastener, completing the locking operation; at the same time, the first fitting surface squeezes the second fitting surface, so that the movable part moves and partially extends out of the shell through the through hole. This unlocking and locking method can be operated with one hand. Due to the provision of the elastic part and the corresponding arrangement, the buckle body can move toward or in the opposite direction, and has the effect of automatic alignment and positioning when locking is required, and can be operated with one hand.

[0018] Preferably, the buckle body is provided with a boss, and the buckle body is provided with a groove body above the boss; the groove body is provided with a first magnet on the side away from the boss. When the buckling parts are provided in groups, the buckle body and the first magnet are provided in groups accordingly. The first magnets provided in groups enable the buckle bodies provided in groups to be magnetically attracted to each other, thereby achieving the effect of automatic alignment when the moving parts are released, and the buckle bodies provided in groups move toward each other under the action of the elastic part and the limitation of the first convex point and the first limiting groove, thereby achieving automatic alignment between the buckle bodies in groups and completing the buckling and locking operation of the bead head. The boss and the groove body are provided to surround the outer periphery of the fastener to limit the fastener, and the fastener is provided with structures corresponding to the boss and the groove body, so that the limiting connection between the buckle body and the fastener is more stable. The provision of the first magnet is conducive to magnetic attraction with the second magnet provided inside the bead head, which can realize automatic alignment of the bead head and facilitate the placement of the bead head between the buckle body. At the same time, due to the mutual attraction between the first magnet and the second magnet, the groups of buckle bodies are in conflict with each other and continue to limit the fastener, avoiding the bead head from falling out of the buckle body due to accidental unlocking due to external force.

[0019] Preferably, the fastening portion is provided with a fastener corresponding to the fastening portion, the fastener comprising a fastener body, a bead head disposed on the fastener body and positioned within the slot body when connected to the fastening portion, a second magnet disposed within the bead head that is magnetically attracted to the first magnet. A magnet slot for mounting the second magnet is disposed within the bead head; in the limited position, the surface of the bead head is in contact with the surface of the boss and the surface of the slot body, with the top of the bead head in contact with the first magnet. The cross-section of the fastener is circular; a bead head protrusion that engages with the slot body is disposed at the upper end of the bead head, the bead head protrusion being disposed above the bead head slot body; a boss and a slot body are disposed within the buckle body, the boss being engaged with the lower end of the bead head, and the upper end of the bead head being engaged with the slot body; the fastener can be confined within the buckle body, completing the locking operation, and the first and second magnets attract each other, making the connection between the bead head and the buckle body more stable; when unlocking, the buckle body moves so that the internal space is insufficient to limit the bead head, thereby allowing the bead head to be pulled out, completing the unlocking operation. A first magnet and a second magnet are provided simultaneously. When the lock is restored to the unlocked state, the movable part is kept pressed. Due to the mutual magnetic attraction between the first and second magnets, the bead head can be automatically positioned between the buckle body. After the movable part is released, the elastic part applies force to the buckle body, reducing the space between the buckle bodies until the end faces of the two buckle bodies abut against each other, thereby causing the buckle body to contact and limit the fastener, completing the locking operation. The provision of the first magnet facilitates magnetic attraction with the second magnet provided inside the bead head, enabling automatic alignment of the bead head. At the same time, due to the mutual attraction between the first and second magnets, the bead head is prevented from being accidentally released from the buckle body due to the unlocking caused by external forces.

[0020] Preferably, a first gasket is provided on one side of the shell, and the first gasket is provided with a gasket opening for the passage of the fastener. The first gasket opening is provided coaxially with the buckle body. A first connecting column is provided inside the shell to be engaged with the first gasket; a gasket opening is provided so that the bead head can pass through the gasket opening and move to the end of the moving path of the buckle body, thereby being locked. Specifically, by pressing the moving part, the buckle body overcomes the force of the spring and moves, so that the space between the relative buckle bodies is increased, and the bead head moves to between the relative buckle body connection lines, and the moving part is released. The relatively arranged buckle bodies are respectively restored to their initial positions under the action of the corresponding elastic parts, so that the boss and the groove body inside the buckle body correspondingly limit the movement of the bead head, thereby completing the locking operation; if an unlocking operation is required, after pressing the moving part, the bead head is manually moved to the outside through the gasket opening, thereby completing the unlocking operation.

[0021] Preferably, a connecting buckle is provided on the surface of the housing, which can be connected to a webbing, wherein the webbing can be connected to a bag, a shoe buckle, a waist or a placket of clothing, so as to correspond to the position of the buckle.

[0022] Preferably, a first limiting groove and a second limiting groove are provided inside the housing, and the first limiting groove and the second limiting groove are provided perpendicular to each other;

[0023] The upper end of the buckle body is provided with a first protrusion that matches the first limiting groove; the upper end of the movable part body is provided with a second protrusion that matches the second limiting groove. The moving path of the first protrusion is limited by the first limiting groove, thereby limiting the moving path of the buckle body; at the same time, the moving path of the second protrusion is limited by the second limiting groove, thereby limiting the moving path of the movable part body, so that the extension direction of the moving path of the buckle body is set perpendicular to the extension direction of the moving path of the movable part body, so that the buckle body is moved in a perpendicular manner through the movement of the movable part body; the moving direction of the extrusion block is limited by the second limiting groove, and the interference block is squeezed so that the buckle body moves along the setting direction of the first limiting groove to overcome the action of the elastic part, so that The extension direction of the moving path of the moving part is perpendicular to the extension direction of the moving path of the buckle body. This structure requires less space and has a compact overall structure, which is conducive to one-handed operation. At the same time, when the re-locking operation is required, pressing the moving part causes the buckle body to move along a limited path, so that there is space between the buckle bodies to insert the fastener. After the fastener is inserted, the pressure on the moving part is released, and the moving part moves along the limited path to return to its original state. At the same time, the buckle body moves toward each other along the limited path to re-lock the fastener. This operation can be performed with one hand, and with the alignment of the first magnet and the second magnet, it is convenient to perform the buckling and locking operation.

[0024] Preferably, a fitting block is provided below the fastener body, a second connecting post is provided below the fitting block, and the second connecting post is engaged with a second gasket. Fabric is fitted between the fitting block and the second gasket; the fabric can be used for bags, shoe buckles, waists, and plackets of clothing.

[0025] This application has achieved beneficial technical effects:

[0026] The utility model controls whether the fastening part moves by the moving part contacting the fastening part. When the moving part and the fastening part are in a non-contacting state, the internal space of the fastening part limits the fastener, thereby completing the locked state; when the fastening part moves, its moving path is perpendicular to the moving direction of the moving part, and the moving part contacts and squeezes the fastening part, so that the fastening part is stretched and moves to complete the unlocked state; after completing the unlocked state, when the fastener needs to be locked again, the moving part is pressed again to put the fastening part in the unlocked state, and the fastener is inserted accordingly.

DETAILED DESCRIPTION

[0039] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0040] The technical solutions of the present application will be described in detail below with specific embodiments.

[0041] Referring to Figures 1 to 10 As shown in the drawings, a buckle includes a shell 1, a buckle 2 arranged in the shell 1, and a moving part 3 for controlling whether the buckle 2 moves or not. The moving direction of the moving path of the moving part 3 is perpendicular to the moving direction of the moving path of the buckle 2. The buckle 2 is controlled by the moving part 3 to move or not. When the moving part 3 and the buckle 2 are not in contact, the internal space of the buckle 2 limits the buckle, thereby completing the locking state. When the buckle 2 moves, the moving path is perpendicular to the moving direction of the moving part 3. The moving part 3 is in contact with and extrudes the buckle 2, so that the buckle 2 is opened and moves, thereby completing the unlocking state. When the buckle needs to be relocked after completing the unlocking state, the moving part 3 is pressed again to make the buckle in the unlocking state, and the buckle is inserted. When the moving part 3 is released, the buckle 2 returns to the state of limiting the buckle. The overall required space is small, and the implementation of this operation is simple and easy to implement. The user can operate with one hand.

[0042] The buckle part 2 includes an elastic part 21 connected to the housing 1 at one end, and a buckle body 22 connected to the end of the elastic part 21 away from the housing 1. The elastic part 21 is provided, and the buckle part 2 is in an initial state when it is not subjected to the force of the moving part 3, which is also a locked state. When unlocking is required, the moving part 3 resists the buckle body 22, so that the buckle body 22 overcomes the elastic force of the elastic part 21 and moves in a direction perpendicular to the moving direction of the moving part. After the buckle body 22 moves, the limited space inside the buckle body 22 is away from the buckle, thereby completing the unlocking operation. The buckle part 2 is arranged in groups, and the two buckle bodies 22 move in opposite directions, so that the space between the buckle bodies 22 is increased to the point where they cannot be interfered with. The buckle 22 is extended and stopped at the end by the elastic action of the elastic part 21. The buckling part 2 is arranged in a group, and the end faces of the two buckle bodies 22 contact each other, and a space is formed inside to limit the buckle, thereby preventing the buckle from falling out of the shell 1. This locking method is simple and can be operated with one hand.

[0043] The buckle body 22 includes a buckle body 221 connected to the elastic portion 21, and a resisting block 222 disposed on the buckle body 221 and opposite to the moving member 3;

[0044] The moving part 3 includes a moving part body 31, an extrusion block 32 arranged at the end of the moving part body 31 and opposite to the interference block 222. Specifically, the elastic part 21 is a spring, the shell 1 is provided with a first card point 211 connected to one end of the spring 22, and the surface of the buckle body 221 is provided with a second card point 220 connected to the other end of the spring. The moving path of the extrusion block 32 overlaps with the interference block 222 in the initial state. One end of the buckle body 221 is connected to the elastic part 21; the interference block 222 is provided on the buckle body 22 and does not overlap with the end of the buckle body 22, so that there is a gap between the interference block 222 and the end of the buckle body 22. The locking mechanism 221 is simple and can be used to unlock the latch 222 and unlock the latch 221 so that the latch 222 can be unlocked easily.

[0045] The width of the extrusion block 32 gradually increases from the end closest to the interference block 222 to the end farther from the interference block 222. The end surface of the extrusion block 32 gradually expands, causing the interference block 222 to be gradually compressed and pressed, overcoming the force of the elastic portion 21 and moving to a certain distance. This increases the space between the buckle bodies 22 to a state where the buckle cannot be restrained from being dislodged or to a state where the buckle is in a state before the fastener is inserted, thereby completing the movement of the buckle body 221 before unlocking or locking. This unlocking and locking method is simple and can be completed with one hand.

[0046] The first contact surface 2221 is provided on the side of the resisting block 222 facing the extruding block 32 . The second contact surfaces 321 are provided on both sides of the extruding block 32 perpendicular to its moving direction. The first contact surface 2221 and the second contact surface 321 are provided facing each other. When the locking cam 321 is in the unlocked position, the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position, and the second locking cam 321 is in the unlocked position,

[0047] The buckle body 221 has a spacing surface 2211 between the abutment block 222 and the end of the buckle body 221. The extrusion block 32 has a third contact surface 322 on one end facing the spacing surface 2211. Both the spacing surface 2211 and the third contact surface 322 have arcuate cross-sections. When unlocked, the spacing surface 2211 and the third contact surface 322 contact each other. When the cam 221 is in the unlocked position, the third engaging surface 322 can enter between the first engaging surface 2221 in the initial state, so that the second engaging surface 321 can fit in and contact with the first engaging surface 2221, and at the same time, the third engaging surface 322 can fit in and contact with the spacing surface, thereby completing the unlocking operation or completing the operation before the fastener is placed in the locked state. The third engaging surface 322 fits in and contacts with the spacing surface 2211, and the limit block and the interference block interfere with each other at multiple positions, and at the same time, prevent the squeezing block 32 from extending into the moving path of the buckle body 221, thereby improving the stability of the unlocked state and the state stability before the fastener is placed in the locked state; the maximum width of the second engaging surface 321 corresponds to the space formed between the two buckle bodies 221 after movement, which is suitable for the fastener to pass through; the squeezing block 32 is provided with a length The third contact surface 322 is less than or equal to the length of the interference block 222 set along the moving direction of the moving part 3; the spacing surface 2211 is set so that there is a certain space under the interference block 222 for the extrusion block 32 to enter, and the extrusion block 32 is provided with a space for the interference and extrusion of the interference block 222. After the extrusion block 332 moves to a certain distance, the third contact surface 322 conflicts with the spacing surface 2211, so that the extrusion block 32 will not extend into the moving path of the buckle body 221 and affect the unlocking operation of the buckle or affect the accommodation of the buckle. The operation of inserting the locking fastener; when in the unlocked state, the third fitting surface 322 conflicts with the spacing surface 2211, which improves the stability of the unlocked state and facilitates one-handed operation. At the same time, the first fitting surface 2221 and the second fitting surface 321 can be fitted together by one-handed operation, so that a space for the fastener to enter is formed between the buckle body 221. After the fastener enters and the pressure on the moving part 3 is released, the buckle body bodies in groups move toward each other, thereby locking the fastener. This operation method can be operated with one hand.

[0048] The housing 1 includes a housing body 10 and a through hole 11 provided on the housing body 10 for the moving member body 10 to move. The moving member body 31 partially extends out of the housing 1 through the through hole 11.

[0049] The moving member 3 further includes a limit block 33 disposed on the moving member body 31 and inside the housing 1 , wherein the limit block 33 is disposed in contact with one end of the extrusion block 32 ;

[0050] The projection of the edge of the through hole 11 and the projection of the maximum stroke of the abutting block 222 are both within the projection range of the limiting block 33 in the direction of the moving path of the moving member 3.

[0051] On one hand, the whole moving member 3 is prevented from being pulled out of the shell 1, and on the other hand, the limiting block 33 abuts against the abutting block 222 in the unlocked state or in the state before the locking buckle is placed, thereby preventing the extrusion block 32 from extending into the buckle body 221 and affecting the insertion operation of the buckle. In the unlocked state, the limiting block 33 abuts against the end surface of the abutting block 222, and the third abutting surface 322 abuts against the spacing surface 2211, thereby preventing the extrusion block 32 from extending into the moving path of the buckle body 221 and affecting the unlocking operation of the buckle 22 or affecting the state before the locking buckle is placed. The limiting block 33 is arranged at a position corresponding to the maximum width of the second abutting surface 321. The limiting block 33 abuts against the end of the extrusion block 32 away from the abutting block. The moving member body 31 extends out of the shell 1 through the through hole 11, thereby facilitating the user to press the moving member 3 and complete the unlocking operation or the operation before the locking buckle is placed;

[0052] The buckling parts 2 and the moving members 3 are arranged in groups, and the connecting lines of the installation positions of the buckling parts 2 and the connecting lines of the installation positions of the moving members 3 are perpendicular to each other. The through holes are arranged in groups. In the unlocked state, the extrusion block 32 extrudes the inner end surfaces of the two abutting blocks 222 on the same side, thereby moving the two buckle bodies 221 in opposite directions, and the space formed between the two buckle bodies 221 after moving is insufficient to abut against and limit the buckle, thereby completing the unlocking operation. When it is needed to return to the locked state again, the buckle is placed between the two buckle bodies 22 by pressing the moving member 3, and the space between the two buckle bodies 221 gradually decreases due to the action of the elastic part 21 after the force on the moving member 3 is removed, thereby abutting against and limiting the buckle 22, and completing the locking operation. At the same time, the first abutting surface 2221 extrudes the second abutting surface 321, thereby moving the moving member 3 and extending out of the shell 1 through the through hole 11. This unlocking and locking method can be operated by one hand. Due to the arrangement of the elastic part 21 and the corresponding arrangement, the buckle bodies 221 can move towards each other or move in opposite directions, and the automatic alignment positioning effect is achieved when locking is needed, thereby enabling one-handed operation.

[0053] The buckle body 221 is provided with a boss 2212, and the buckle body 221 is provided with a groove 2213 above the boss 2212; the groove 2213 is provided with a first magnet 2214 on the side away from the boss. When the buckle parts 2 are arranged in groups, the buckle bodies 221 and the first magnets 2214 are arranged in groups accordingly. The first magnets 2214 arranged in groups enable the buckle bodies 221 arranged in groups to be magnetically attracted to each other, achieving the effect of automatic alignment when the moving part 3 is released, and through the force of the elastic part 21 and the first protrusion and the first limiting groove, they move toward each other, achieving automatic alignment between the buckle bodies 221 in groups, completing the buckle locking operation of the bead head. The boss 2212 and the groove 2213 are provided to surround the outer periphery of the fastener to limit the fastener. At the same time, the fastener is provided with structures corresponding to the boss 2212 and the groove 2213, so that the limiting connection between the buckle body 22 and the fastener is more stable. The provision of the first magnet 2214 is conducive to magnetic attraction with the second magnet provided inside the bead head, which can realize automatic alignment of the bead head and facilitate the placement of the bead head between the buckle body 221. At the same time, due to the mutual attraction between the first magnet 2214 and the second magnet, the grouped buckle body 221 is in conflict with each other and continuously limits the fastener, avoiding the bead head from falling out of the buckle body due to accidental unlocking due to external force.

[0054] The fastening portion 2 is correspondingly fastened with a fastener 4. The fastener 4 includes a fastener body 41, a bead head 42 disposed on the fastener body 41 and positioned within the groove 2213 when connected to the fastening portion 2. A second magnet 43 is disposed within the bead head 42, which is magnetically attracted to the first magnet 2214. A magnet slot 421 is disposed within the bead head 42 for receiving the second magnet 43. In the restricted position, the surface of the bead head 42 is in contact with the surface of the boss 2212 and the surface of the groove 2213, and the top of the bead head 42 contacts the first magnet 2214. The cross-section of the fastener 4 is circular; the upper end of the bead head 42 is provided with a bead head protrusion that is engaged with the groove body, and the bead head protrusion is provided above the bead head groove body; a boss 2212 and a groove body 2213 are provided inside the buckle body 221, and the boss 2212 is engaged with the lower end part of the bead head 42, and the upper end of the bead head 42 is engaged with the groove body 2213; so that the fastener can be limited inside the buckle body 221 to complete the locking operation, and the first magnet 2214 and the second magnet 43 attract each other, so that the connection between the bead head 42 and the buckle body 221 is more stable; when unlocking, the buckle body 221 moves so that its internal space is not enough to limit the bead head 42, so that the bead head 42 can be pulled out to complete the unlocking operation. The first magnet 2214 and the second magnet 43 are provided at the same time. When the lock is in the unlocked state and needs to be restored to the locked state, the movable part is kept pressed. Since the first magnet 2214 and the second magnet 43 have a mutual magnetic attraction, the bead head 42 can be automatically positioned between the buckle body 221. After the movable part 3 is released, the elastic part applies force to the buckle body 221, causing the space between the buckle body 221 to decrease until the end faces of the two buckle body 221 abut against each other, so that the buckle body 221 abuts against the buckle, completing the locking operation. The provision of the first magnet 2214 is conducive to magnetic attraction with the second magnet 43 provided inside the bead head 42, which can realize automatic alignment of the bead head. At the same time, since the first magnet 2214 and the second magnet 43 are in a state of mutual attraction, the bead head is prevented from being accidentally unlocked due to external force and falling out of the buckle body 221.

[0055] A first gasket 12 is provided on one side of the housing 1 , and a gasket opening 121 is provided on the first gasket 12 for a fastener to pass through. The gasket opening 121 is coaxially arranged with the buckle body 22 . A first connecting column 13 is provided inside the shell 1 to be embedded and connected to the first gasket 12; the first connecting column 13 is embedded with the connecting hole provided on the first gasket 12 and then machine-bound together; a gasket opening 121 is provided so that the bead head 42 can pass through the gasket opening 121 and move to the end of the moving path of the buckle body 221, so that it can be locked. Specifically, by pressing the moving part 3, the buckle body 221 overcomes the force of the spring and moves, so that the space between the relative buckle bodies 22 is increased, and the bead head 42 moves to between the connecting lines of the relative buckle bodies 22, and the moving part 3 is released. The relatively arranged buckle body 221 is respectively restored to the initial position under the action of the corresponding elastic part 21, so that the boss 2212 and the groove body 2213 inside the buckle body 221 correspondingly limit the movement of the bead head 42, thereby completing the locking operation; if an unlocking operation is required, after pressing the moving part 3, the bead head 42 is manually moved to the outside through the gasket opening 121, thereby completing the unlocking operation.

[0056] The surface of the housing 1 is provided with a connecting buckle 14. The connecting buckle 14 can be connected to a webbing 15, wherein the webbing 15 can be connected to a bag, a shoe buckle, a waist and a placket of clothing, so as to correspond to the position of the buckle.

[0057] A first limiting groove 16 and a second limiting groove 17 are provided inside the housing 1 , and the first limiting groove 16 and the second limiting groove 17 are provided perpendicular to each other;

[0058] The upper end of the buckle body 221 is provided with a first protrusion 2215 that cooperates with the first limiting groove 16; the upper end of the movable part body 31 is provided with a second protrusion 34 that cooperates with the second limiting groove 17. The moving path of the first protrusion 2215 is limited by the first limiting groove 16, thereby limiting the moving path of the buckle body 221; at the same time, the moving path of the second protrusion 34 is limited by the second limiting groove 17, thereby limiting the moving path of the movable part body 31, so that the extension direction of the moving path of the buckle body 221 is set perpendicular to the extension direction of the moving path of the movable part body 31, so that the buckle body 221 is moved in a perpendicular manner through the movement of the movable part body 31; the moving direction of the extrusion block 32 is limited by the second limiting groove 17, and the interference block 222 is squeezed so that the buckle body 221 overcomes the elastic part 21 along the setting direction of the first limiting groove 16. The movable part 3 is moved by the force of the action of the buckle body 22, so that the extension direction of the moving path of the movable part 3 and the extension direction of the moving path of the buckle body 22 are perpendicular to each other. The space required for this structure is small, and the overall structure is compact, which is conducive to one-handed operation. At the same time, when the re-locking operation is required, pressing the movable part 3 causes the buckle body 221 to move along a limited path, so that there is space between the buckle body 221 for inserting the fastener. After the fastener is inserted, the pressure on the movable part 3 is released, and the movable part moves along the limited path to restore to its original state. At the same time, the buckle body 221 moves toward each other along the limited path to re-lock the fastener. This operation can be performed with one hand, and with the alignment of the first magnet 2214 and the second magnet 43, it is convenient to perform the buckling and locking operation.

[0059] A fitting block 44 is provided below the fastener body 41, and a second connecting post 45 is provided below the fitting block 44. The second connecting post 45 engages with a second gasket 46. The second connecting post 45 engages with the connecting holes provided in the second gasket 46 and is then machine-stitched together. A fabric 5 is fitted between the fitting block 44 and the second gasket. The fabric can be used for bags, shoe buckles, waistbands, and plackets of clothing.

[0060] The cross-section of a single buckle body along the vertical direction of the axis is semicircular, the interference block is vertically arranged on the arc surface of the buckle body, wherein the spacing surface is arranged on the arc surface, the cross-section of the interference block is square, wherein the first fitting surface is arranged on the side of the interference block close to the axis of the buckle body;

[0061] This technical solution aims to solve the problem that the adjustment buckle is inconvenient to use on clothing buckles, and is specifically applied to clothing items such as jackets, hats, shoes, backpacks, suitcases, and helmets that require buckling and locking.

[0062] And this technical solution can achieve the following technical effects: 1. The moving part protrudes from the outside of the shell, which is easy to press, and unlocking and locking can be operated with one hand; 2. There is a magnetic structure inside, so that the product can be automatically aligned, which is easy to use; 3. The press keys are located on both sides of the product, and there is a magnetic attraction inside for mutual adsorption, which is not easily affected by external force and caused by accidental touch to open the luggage, so that the tolerance rate of the product being separated by external force is increased; 4. It can be used on different types of clothing such as luggage, shoe buckles, waist and placket of clothing.

[0063] The bag is fastened and locked with one hand. Pressing the raised top portion (the moving part) activates the internal mechanism to unlock the buckle. The internal magnetic structure then automatically aligns the two components, securing the buckle. Because the buttons are located on both sides of the product and the internal magnetic attraction acts as a mutual attraction, it's less susceptible to accidental opening due to external forces.
