Description

Technical Field

[0001] The utility model relates to the technical field of backpack straps of bags, and particularly relates to a magnetic snap fastener. Background Art

[0002] In the prior art, the commonly used snap fasteners generally adopt a male snap and a female snap. The snap and the snap sleeve are respectively arranged on the male snap and the female snap. When fastening, the male snap is inserted into the female snap, and the deformation of the hook of the male snap is used to be stuck in the notches on both sides of the female snap; when opening, the hook of the male snap stuck in the notches on both sides of the female snap is pressed inward to open the snap fastener.

[0003] For the existing mechanical snap fastener structure, there are many connecting parts in the mechanical snap fastener structure. When the user inserts the two snap fasteners together, the operation steps are more cumbersome. And because the connecting parts are connected to each other, if there is a mistake in one step during the operation process, the snap fasteners cannot be inserted in place, which affects the work efficiency. Secondly, after the snap fasteners are assembled, they should be in a locked state. Some snap fasteners are prone to looseness after being assembled, and the fixation between the two workpieces is not firm. At the same time, the existing snap fasteners generally have a certain hardness, and the clearance between the plug and the snap fastener is small. During the use process, the adjustment in the force direction cannot be carried out, which is easy to cause damage to itself and the connected objects.

[0004] Magnetic snap fastener products are a common type of clothing accessories and are widely used in clothing. Magnetic snap fasteners are mostly made of plastic or metal materials and are often used with webbing on clothing to play a role in adjusting and fixing the webbing. Magnetic snap fasteners are based on connecting clothes for tightening adjustment. Now they have gradually developed to be more artistic and decorative in addition to maintaining their original functions. Quick-release rotary snap fasteners are mostly used for luggage and connecting backpack straps and need to be frequently detached. However, the existing magnetic snap fasteners usually use linear sliding out as the guiding direction, and other directions such as the side are not applicable for detachment, resulting in that the magnetically attracted magnetic snap fasteners can only be detached in a fixed direction, making it difficult to detach the magnetic snap fasteners and inconvenient for daily use.

[0005] Therefore, how to provide a magnetic snap fastener that can solve the problem of inconvenient detachment of the magnetically attracted magnetic snap fastener to improve the user experience is a technical problem that those skilled in the art need to solve at present.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0042] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the following will further describe the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0043] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0044] The purpose of the present utility model is to provide a magnetic suction plug buckle, which can solve the problem that it is inconvenient to remove the magnetic buckle after magnetic suction, so as to improve the user experience.

[0045] Please refer to Figure 1 、 Figure 2 and Figure 3 To achieve the above object, the present utility model provides a magnetic suction plug buckle, which includes a plug member 100 and a socket member 200.

[0046] The plug member 100 includes a plug body 110, a clamping member 120 provided with a clamping shoulder 121 and a first magnet 122, two limiting portions provided on the plug body 110, and a conical guiding surface 130 located between the two limiting portions.

[0047] The socket member 200 includes a socket body 210 provided with a card slot 211, and a locking portion 220 connected to the socket body 210 and covering part of the card slot 211. The socket body 210 is provided with a second magnet 212 that can be magnetically attracted to the first magnet 122, so that the clamping member 120 moves into the card slot 211, and part of the clamping shoulder 121 is in clamping fit with the locking portion 220. The socket member 200 and the plug member 100 can rotate relative to the axis of the clamping member 120 and form a rotation range between the two limiting portions.

[0048] The socket member 200 has a first end, and the first end faces the conical guiding surface 130. The socket member 200 can slide in the rotation range in the direction towards the first end and is guided by the conical guiding surface 130, so that the socket member 200 disengages from the plug member 100. The first end of the socket member 200 is located at one end of the socket member 200 away from its own webbing stop 112.

[0049] The card component 120 includes a shaft body and a locking shoulder 121 provided on the outer periphery of the shaft body. Preferably, the shaft body is of a columnar structure. In order to more effectively form the locked state between the locking shoulder 121 and the locking portion 220, the locking shoulder 121 is formed in a circular ring shape. The locking shoulder 121 can also be in a polygonal shape other than the circular ring shape, etc. The locking portion 220 forms an inner peripheral edge different from the outer periphery of the above-mentioned locking shoulder 121, so that the condition that the locking shoulder 121 and the locking portion 220 are in a locked state along the axis direction of the shaft body can be satisfied when the jack component 200 and the plug component 100 are combined.

[0050] Please refer to Figure 5 、 Figure 6 and Figure 7 When the jack component 200 rotates clockwise relative to the plug component 100 around the axis of the card component 120 by a certain angle, the jack component 200 rotates to abut against a limiting portion, which is the first limit state of the rotation of the jack component 200 relative to the plug component 100; when the jack component 200 rotates counterclockwise relative to the plug component 100 around the axis of the card component 120 by a certain angle, the jack component 200 rotates to abut against another limiting portion, which is the second limit state of the rotation of the jack component 200 relative to the plug component 100. Whether it is the first limit state, the second limit state, or the intermediate state between the first limit state and the second limit state, the first end portion can slide along the conical guide surface 130 in the direction of its own orientation.

[0051] Wherein, a side surface 213 is formed at the edge of the jack component 200 to achieve the abutment between the jack component 200 and the limiting portion. The side surface 213 has a card position point for abutting against the limiting portion. In the first limit state, the card position point of one side surface 213 has a first tangent line parallel to the following bottom surface 111. In the second limit state, the card position point of the other side surface 213 has a second tangent line parallel to the following bottom surface 111. The included angle α between the two tangent lines is the included angle corresponding to the rotation range. Preferably, the size of the included angle α is 120°±5°, so as to preferably achieve the insertion of the plug component 100 into the jack component 200 in multiple selectable directions and the extraction of the jack component 200 in multiple selectable directions.

[0052] The magnetic attraction of the first magnet 122 and the second magnet 212 causes the card member 120 to move into the card slot 211, and part of the card stop shoulder 121 is clamped and fitted with the card fixing portion 220 to limit the separation of the card member 120 and the card slot 211 in the axial direction of the card member 120. At the same time, the socket member 200 and the plug member 100 can rotate relative to the axis of the card member 120 and form a rotation range between the two limiting portions. The socket member 200 has a first end facing the conical guide surface 130. When the socket member 200 and the plug member 100 need to be separated, the socket member 200 can slide in the rotation range in the direction of the first end and is guided by the conical guide surface 130. By squeezing the socket member 200 and the plug member 100 towards the axis position of the card member 120, the socket member 200 can be quickly separated in multiple directions along the conical guide surface 130, which can solve the problem that the magnetic buckle released by magnetic attraction is inconvenient, so as to improve the user experience.

[0053] In some embodiments, the conical guide surface 130 and the card member 120 can be concentrically arranged, so that the distance between any point in the same cross-section perpendicular to the axial direction of the card member 120 and the card member 120 is equal, which is convenient for the socket member 200 to rotate to any position within the rotation range and slide the same distance to be released, so that when the user uses the socket member 200 and the plug member 100, the hand feeling is consistent.

[0054] Please refer to Figure 4 , in this embodiment, an upper magnet groove 214 for accommodating the second magnet 212 is provided in the socket body 210, and a lower magnet groove 123 for fixing the first magnet 122 is provided on the card member 120, and the lower magnet groove 123 is located in the middle of the card member 120.

[0055] The magnetic attraction between the second magnet 212 in the upper magnet groove 214 and the first magnet 122 in the lower magnet groove 123 makes the axes of the upper magnet groove 214 of the socket member 200 and the lower magnet groove 123 of the plug member 100 the same after magnetic attraction.

[0056] The card fixing portion 220 includes an annular portion 221 concentrically arranged with the upper magnet groove 214 and two extending portions 222 extending from the inner circle of the annular portion 221 towards the axis of the upper magnet groove 214. The annular portion 221 is a semi-circular ring to increase the space for the card member 120 to enter the card slot 211, and the two extending portions 222 can be attached to one side of the card stop shoulder 121 close to the plug body 110.

[0057] It can be understood that when the second magnet 212 is magnetically attracted to the first magnet 122, the locking shoulder 121 will partially cooperate with the extension portion 222 in the locking portion 220 to limit the axial separation of the socket component 200 and the plug component 100. Considering that the socket component 200 can rotate clockwise and counterclockwise relative to the plug component 100, the two extension portions 222 should adopt a symmetrical structure to simultaneously limit both sides of the locking shoulder 121.

[0058] The side of the extension portion 222 that is away from the outer periphery of the annular portion 221 is preferably a planar structure. By setting the extension portion 222 smaller, it limits the separation of the socket component 200 and the plug component 100 from each other, and facilitates the snap-fitting of the shoulder 121 and the extension portion 222 during the rapid magnetic attraction between the second magnet 212 and the first magnet 122.

[0059] Preferably, the adjacent ends of the two extension portions 222 are connected by a connecting portion 223, and the connecting portion 223 has a smooth inner circumference. Through the contact between the inner circumference and the outer circumference of the shaft, the connecting portion 223 can rotate and abut against the shaft of the clamping member 120, so as to facilitate the relative rotation of the socket member 200 and the plug member 100, and can solve the problem of the wire belt folding caused by the inability of the socket member 200 and the plug member 100 to rotate relative to each other in the prior art.

[0060] It can be understood that the plug body 110 includes a bottom surface 111, the clamping member 120 is vertically arranged on the bottom surface 111, and the locking shoulder 121 is located at the end of the clamping member 120 away from the bottom surface 111, the conical guide surface 130 includes a lower arc line with a smaller diameter and an upper arc line with a larger diameter, and the lower arc line is located inside the bottom surface 111, the locking shoulder 121 is a tapered structure with an inclined surface or a curved surface, and the distance between the smaller end of the locking shoulder 121 and the bottom surface 111 is greater than the distance between the larger end of the locking shoulder 121 and the bottom surface 111, so as to facilitate the magnetic attraction process of the second magnet 212 and the first magnet 122.

[0061] See also Figure 10 In this embodiment, the socket body 210 also includes an abutment portion 215 connected to the outer edge of the annular portion 221, and the abutment portion 215 is concentrically arranged with the upper magnet groove 214. The abutment portion 215 has the same taper as the conical guide surface 130, so that the abutment portion 215 slides along the conical guide surface 130.

[0062] The contact portion 215 defines an opening that communicates with the slot 211 , so as to facilitate cleaning of foreign matter in the slot 211 .

[0063] See also Figure 8 and Figure 9, the centers of the projections of the conical guide surface 130, the abutting portion 215, and the locking shoulder 121 on the bottom surface 111 are the same. The staff squeezes the plug member 100 and the socket member 200 towards the axial position of the locking shoulder 121. The abutting portion 215 contacts the conical guide surface 130 and climbs along the conical guide surface 130. Within the defined angular range, the socket member 200 can be rotated to any angle and can be withdrawn along a straight line.

[0064] In this embodiment, at least one of the plug body 110 and the socket body 210 is provided with a webbing stop 112 for connecting the webbing, and the closed-loop connection of the webbing is realized through the plug body 110 and the socket body 210.

[0065] Please refer to Figures 11 to 14 , in some embodiments, the plug body 110 is configured as a disk-shaped structure having a buckle point 150 and / or a sewing edge 140. The fixing of the plug body 110 is realized through a binder 160 and a fixing plate provided on one side of the binder 160. Specifically, the fixing plate is provided with a buckle groove 180 for snap-fitting with the buckle point 150, so as to realize the snap-fitting process of the buckle point 150 of the disk-shaped structure passing through the binder 160 and the fixing plate. In addition, the fixing plate is further provided with a pressing point 170 facing the binder 160, and the pressing point 170 is used to abut against the binder 160 to achieve no gap after the plug body 110 and the fixing plate are buckled.

[0066] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0067] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
