Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to a connecting buckle and a nursing bra. Background Technology

[0002] Nursing bras are functional bras specifically designed for breastfeeding women. Traditional nursing bras typically feature an openable cup design, allowing breastfeeding by opening one cup when needed without removing the entire bra. Current technology generally uses a nursing clasp with hooks and loops between the upper part of the cup and the shoulder strap. This clasp usually consists of a hook with a semi-circular notch and an inverted U-shaped buckle that interlocks, requiring manual unhooking with both hands. This is inconvenient for pregnant women holding a baby. Utility Model Content

[0012] In some embodiments, the end of the first sliding channel is provided with a blocking element; and / or, the end of the second sliding channel is provided with a blocking element.

[0013] In some embodiments, the width of the first sliding channel is equal to or greater than the sum of the width of the first protrusion and the depth of the slot; when the first buckle and the second buckle are connected, the slot located on the side wall of the first sliding channel is in an interference fit with the hook under the action of magnetic force, and a gap is formed between the other side wall of the first sliding channel and the end of the first protrusion; under the action of external force, the first protrusion can be displaced into the gap to separate the slot from the hook.

[0014] In some embodiments, the end of the second buckle body near the first protrusion is a rotating end, and the side of the rotating end away from the first buckle body is a first inclined surface.

[0015] In some embodiments, the first protrusion is located on one side of the second sliding channel, and the other side of the second sliding channel is provided with a first connecting end; the first sliding channel is located on one side of the second protrusion, and the other side of the second protrusion is provided with a second connecting end; the first connecting end and the second connecting end are located on the same side, and an angle space is formed between them; in the state where the hook and the slot are separated, the first connecting end can rotate within the angle space and fit against the second connecting end to restore the unhooked state.

[0034] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0036] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0037] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0038] It should be noted that the connecting buckle 100 in this embodiment of the present invention can be used to connect two parts to be connected into one unit. For example, it can be applied to a nursing bra to connect the bra body and the shoulder strap into one unit. Of course, it can also be used to connect other devices that need to be connected into one unit, and no special limitation is made here.

[0039] This utility model provides a connecting buckle 100, such as... Figures 1 to 7 As shown, the connecting buckle 100 includes a first buckle body 1 and a second buckle body 2; the first buckle body 1 is in a connected state or an unbuckled state relative to the second buckle body 2;

[0040] The first fastener 1 is provided with a first magnetic element 111, and the second fastener 2 is provided with a second magnetic element 211. The first fastener 1 is connected to the second fastener 2 through the magnetic attraction of the first magnetic element 111 and the second magnetic element 211. It can be understood that the first fastener 1 and the second fastener 2, through the magnetic attraction of the two magnetic elements, can quickly form a connected state in a static attracted position or a disengaged state that can be separated from each other. That is, the first fastener 1 and the second fastener 2 are attracted and fixed by the magnetic force, and can be disengaged by overcoming the magnetic force under the action of external force, making the operation simple and convenient.

[0041] The first buckle body 1 has a first sliding channel 12, and the second buckle body 2 has a sliding part. When the second buckle body 2 is in a connected state relative to the first buckle body 1, the sliding part is confined within the first sliding channel 12. When the second buckle body 2 is in an unfastened state relative to the first buckle body 1, the sliding part slides relative to the first buckle body 1 along the first sliding channel 12 to the outside of the first sliding channel 12. It can be understood that when the first buckle body 1 and the second buckle body 2 are in a connected state, the first magnetic element 111 and the second magnetic element 211 are in a stationary attracted position, and at this time, the sliding part of the second buckle body 2 is confined within the first sliding channel 12. The first sliding channel 12 limits the sliding part of the second buckle body 2 to form an auxiliary positioning, effectively preventing the second buckle body 2 from disengaging from the first buckle body 1. This ensures that only by applying force directionally to the second buckle body 2 along the direction of the first sliding channel 12 can the second buckle body 2 disengage from the first buckle body 1 to achieve the unfastened state. It should be noted that when the connecting buckle 100 is used in a nursing bra to connect the bra body and shoulder straps together, the bra body includes conventional structures such as the underband, bra band, side panels, and underband. The first buckle 1 is located at the end of the shoulder strap, and the second buckle 2 is located on the upper side of the bra body. The bra body is connected to the shoulder strap through the connection between the second buckle 2 and the first buckle 1. When wearing the nursing bra, a downward pulling force is naturally generated on the second buckle 2, thereby providing support to the bra body through the shoulder strap. Therefore, in this embodiment, the first direction is different from the direction of the force exerted on the second buckle 2 when wearing the nursing bra, to prevent the second buckle 2 from disengaging from the first sliding channel 12 and unfastening from the first buckle 1 when worn. The sliding part can be inserted from the beginning of the first sliding channel 12 and can slide along the first sliding channel 12 to a stationary engaging position under the guidance of magnetic force, so that the first buckle 1 and the second buckle 2 are connected.

[0042] The specific method for untying the knot is as follows:

[0043] When the second buckle 2 is in the connected state, under the action of an external force applied by one finger of a single hand, the second buckle 2 moves against the magnetic force relative to the first buckle 1 along one side of the first sliding channel 12.

[0044] When the first buckle 1 is in the connected state, under the external force applied by the other finger of the hand, the first buckle 1 moves against the magnetic force relative to the second buckle 2 along the other side of the first sliding channel 12.

[0045] When the second buckle 2 moves out of the first sliding channel 12 of the first buckle 1, the second buckle 2 returns to the unbuckled state relative to the first buckle 1 from the connected state.

[0046] In summary, the first buckle body 1 and the second buckle body 2 of the connecting buckle 100 can quickly form a connected or unbuckled state through the magnetic attraction of two magnetic components. The first buckle body 1 is provided with a first sliding channel 12, and the second buckle body 2 is provided with a sliding part. The first buckle body 1 and the second buckle body 2 are limited and fixed within the first sliding channel 12 by the sliding part, which effectively improves the firmness of the first buckle body 1 and the second buckle body 2 in the connected state. When it is necessary to unbuckle, the second buckle body 2 can be oriented to detach along the direction of the first sliding channel 12 by applying force with one hand, thereby unbuckled. This allows for sliding unbuckle according to the usage habits of pregnant women, improving the convenience of operation.

[0047] In some embodiments, a slot 112 is provided on the side wall of the first sliding channel 12; the sliding part is a first protrusion 21 disposed on the second buckle body 2 and slidingly engaged with the first sliding channel 12, and a hook 214 matching the slot 112 is provided on one side of the first protrusion 21; when the first buckle body 1 and the second buckle body 2 are connected, the first protrusion 21 is located in the first sliding channel 12 and abuts against the inner wall of the first sliding channel 12, the first magnetic element 111 and the second magnetic element 211 are in a static attracted position, and the hook 214 is engaged in the slot 112 to form an engaged state. Understandably, the first protrusion 21 can be inserted from the beginning of the first sliding channel 12 and can slide along the first sliding channel 12 to a stationary engaging position under the guidance of magnetic force, forming a locking state. At this time, the first buckle body 1 and the second buckle body 2 are in a connected state. Under the limitation of the slot 112 and the inner wall of the first sliding channel 12, the first protrusion 21 can only move in the opposite direction along the first sliding channel 12 to restore the unlocking state under the action of external force.

[0048] In some embodiments, the second buckle body 2 is provided with a second sliding channel 23 adjacent to the first protrusion 21, and the first buckle body 1 is provided with a second protrusion 11 adjacent to the first sliding channel 12, which slides and engages with the second sliding channel 23. When the first buckle body 1 and the second buckle body 2 are connected, the second protrusion 11 is located within the second sliding channel 23. It can be understood that the first sliding channel 12 and the second protrusion 11 engage to form a concave-convex structure on the surface of the first buckle body 1, and the second sliding channel 23 and the first protrusion 21 engage to form a concave-convex structure on the surface of the second buckle body 2. The first protrusion 21 slides in the first sliding channel 12, and the second protrusion 11 slides in the second sliding channel 23, thereby forming a double-channel sliding structure, which improves the accuracy and safety of sliding and effectively prevents slippage.

[0049] In some embodiments, the first protrusion 21 and the second protrusion 11 are provided with cavities, and the second magnetic element 211 is disposed in the cavity of the first protrusion 21, and the first magnetic element 111 is disposed in the cavity of the second protrusion 11. By embedding magnetic elements inside the first protrusion 21 and the second protrusion 11, the magnetic elements can be effectively prevented from falling off, and the aesthetics are improved. Furthermore, the first magnetic element 111 and the second magnetic element 211 are respectively located inside the second protrusion 11 and the first protrusion 21, so that the first magnetic element 111 and the second magnetic element 211 are not stacked together, but form an interlocking, side-attracting structure. The first buckle body 1 and the second buckle body 2 interlock vertically, with the second buckle body 2 located on the outer side. This ensures that when the first buckle body 1 and the second buckle body 2 are connected, the two magnetic elements are on the same plane, thereby ensuring the magnetic connection effect while reducing the overall thickness of the connecting buckle 100, effectively improving wearing comfort.

[0050] In some embodiments, the first magnetic element 111 and the second magnetic element 211 are magnetically attracted to each other on the side where the second protrusion 11 contacts the first protrusion 21, and the first magnetic element 111 corresponding to the top of the second protrusion 11 and the second magnetic element 211 corresponding to the top of the first protrusion 21 are magnetically repelled. Understandably, by using a structure where the two magnetic elements repel each other on their front sides and attract each other on their sides, the second protrusion 11 can slide along the first sliding channel 12 to a locked state under the guidance of magnetic force when placed at the beginning of the first sliding channel 12. Furthermore, the magnetic force on the side where the two magnetic elements contact each other is greater than the magnetic force on the other side (the other side has a weaker magnetic force, requiring less force to open), thus avoiding misalignment and ensuring a secure lock and effortless opening and closing.

[0051] In some implementations, such as Figure 1 and Figure 2As shown, the width of the first sliding channel 12 is equal to or greater than the sum of the width of the first protrusion 21 and the depth of the slot 112; when the first buckle 1 and the second buckle 2 are connected, the slot 112 located on the side wall of the first sliding channel 12 is press-fitted with the hook 214 under the action of magnetic force, and a gap is formed between the other side wall of the first sliding channel 12 and the end of the first protrusion 21; under the action of external force, the first protrusion 21 can be displaced into the gap so that the slot 112 and the hook 214 are separated. Understandably, the width of the first sliding channel 12 is equal to or greater than the sum of the width of the first protrusion 21 and the depth of the slot 112. In this embodiment, the width of the first sliding channel 12 is the sum of the width of the first protrusion 21 and the depth of the slot 112, so that the first protrusion 21 can move along the direction of the gap to separate the slot 112 from the hook 214. Then, an external force is applied to the second buckle 2 to make it lift up relative to the first buckle 1. That is, one end of the second buckle 2 is the fulcrum. An external force is applied to the second buckle 2, so that the second buckle 2 is pried open away from the first buckle 1 with the fulcrum as the fixed point to form an open state. That is, the second buckle 2 can be unfastened by lifting or sliding. Therefore, different unfastening methods can be selected according to the pregnant woman's usage habits or hand position, improving the convenience of operation.

[0052] In some implementations, such as Figure 6 As shown, the end of the second buckle 2 near the first protrusion 21 is a rotating end 212. The side of the rotating end 212 away from the first buckle 1 is a first inclined surface 2121. The side of the rotating end 212 away from the first buckle 1 is the top surface of the rotating end 212, that is, the top surface of the rotating end 212 has an inclined surface structure, that is, the top surface of the rotating end 212 is inclined downward towards its own end to form the inclined surface. When unfastening by flipping, the end of the second buckle 2 near the first protrusion 21 is used as a fulcrum. By applying external force to the second buckle 2, the second buckle 2 is pried open away from the first buckle 1 with the fulcrum as a fixed point to form a flipped state. Therefore, by making the top surface of the end of the second buckle 2 near the first protrusion 21 an inclined surface structure, when the second buckle 2 is flipped open relative to the first buckle 1 by one hand, the rotating end 212 of the second buckle 2 can be effectively prevented from hindering the flipping process.

[0053] In some implementations, such as Figure 7As shown, the first protrusion 21 is located on one side of the second sliding channel 23, and the other side of the second sliding channel 23 is provided with a first connecting end 213 with a through hole; the first sliding channel 12 is located on one side of the second protrusion 11, and the other side of the second protrusion 11 is provided with a second connecting end 16 with a through hole; the first connecting end 213 and the second connecting end 16 are located on the same side, and an angled space is formed between them; when the hook 214 is separated from the slot 112, the first connecting end 213 can rotate within the angled space and fit against the second connecting end 16 to return to the unfastened state. Specifically, in this embodiment, the side of the first connecting end 213 facing the second connecting end 16 is a second inclined surface 2131, and when the first buckle body 1 and the second buckle body 2 are connected, the angled space is formed between the second inclined surface 2131 of the first connecting end 213 and the second connecting end 16. In addition, a third inclined surface can also be formed at the position corresponding to the second connecting end 16 and the second inclined surface 2131, so that an outwardly opening triangular groove is formed between the second inclined surface 2131 of the first connecting end 213 and the third inclined surface of the first buckle body 1. The inclined structure of the first connecting end 213 allows external force to be applied to the second buckle 2, causing it to rotate away from the first buckle 1 and open. This means the second buckle 2 can be opened in two ways: one is by applying external force to the rotating end 212, causing it to pry open away from the first buckle 1; the other is by applying external force to the first connecting end 213, causing it to rotate away from the first buckle 1 and open. Therefore, different unfastening methods can be chosen based on the pregnant woman's usage habits or hand position, further improving ease of operation.

[0054] In some embodiments, a step 24 is provided on the side of the second sliding channel 23 near the first connecting end 213. When the first buckle body 1 and the second buckle body 2 are connected, a gap is formed between the end of the second protrusion 11 and the step 24, and the gap is consistent with the depth of the slot 112. This allows the step 24 to prevent the second buckle body 2 from moving further out when the hook 214 is separated from the slot 112, making it easier for the pregnant woman to unfasten the buckle at this time.

[0055] In some implementations, such as Figure 5As shown, a blocking member 14 is provided at the end of the first sliding channel 12; and / or, a blocking member 14 is provided at the end of the second sliding channel 23. It should be noted that when the connecting buckle 100 is installed on a nursing bra, the end of the first sliding channel 12 corresponds to the inner side of the first sliding channel 12 near the pregnant woman's breast, and the outer side corresponds to the side near the armpit. Therefore, by providing the blocking member 14 at the end of the first sliding channel 12, the second buckle 2 can be restricted from further sliding when it moves to the end and abuts against the blocking member 14. With a blocking member 14 at the end of the first sliding channel 12, the first protrusion 21 slides along the first sliding channel 12 to a stationary engaging position under the guidance of magnetic force. At the same time, the first protrusion 21 abuts against the blocking member 14, and the blocking member 14 prevents the first protrusion 21 from sliding out from one end. During the process of returning to the unlocked state under the action of external force, the first sliding channel 12 becomes a one-sided channel due to the further limitation of the blocking member 14. The first protrusion 21 can only return along the original path of the first sliding channel 12 under the action of external force to return to the unlocked state.

[0056] With the blocking member 14 at the end of the second sliding channel 23, the second protrusion 11 slides along the second sliding channel 23 to a stationary engaging position under the guidance of magnetic force. At the same time, the second protrusion 11 abuts against the blocking member 14, and the blocking member 14 prevents the second protrusion 11 from sliding out from one end. Specifically, to return to the unlocked state under the action of external force, the second sliding channel 23 becomes a one-sided channel under the further limitation of the blocking member 14, and the second protrusion 11 can only return along the original path of the second sliding channel 23 under the action of external force, returning to the unlocked state.

[0057] In some implementations, such as Figure 8 As shown, the first sliding channel 12 is inclined downwards, with its starting position higher than its ending position. The shape of the sliding part is adapted to the shape of the first sliding channel 12. Specifically, the sliding extension direction of the first sliding channel 12 forms an angle with the horizontal direction, and the first sliding channel 12 is inclined downwards from the outside to the inside, so that the first sliding channel 12 forms a parallelogram groove shape. The sliding part also adapts to the shape of the first sliding channel 12, forming a parallelogram protrusion. This allows the second buckle 2 to have a higher center of gravity than when it is in a static engaging position when it is at the starting position of the first sliding channel 12. The second buckle 2 can automatically slide downwards to the engaging state under the action of magnetic force and chest gravity, improving the stability of the engaging state. When it is necessary to unfasten, an external force needs to be applied to push the second buckle 2 upwards to unfasten it, which can effectively avoid the problem of accidental unfastening and improve the stability of the connection state.

[0058] This utility model also provides a nursing bra, which includes a bra body, a left shoulder strap, a right shoulder strap, and a connecting buckle 100 as described above. The first buckle 1 is disposed on the shoulder strap, and the second buckle 2 is disposed on the bra body. The bra body is connected to the shoulder strap via the connection between the second buckle 2 and the first buckle 1. The first buckles 1 on the left and right shoulder straps are symmetrical. The entrance to the first sliding channel 12 of the first buckle 1 on the left shoulder strap is located on the left outer side, and the entrance to the first sliding channel 12 of the first buckle 1 on the right shoulder strap is located on the right outer side. Specifically, one end of each first buckle 1 is provided with a first ring buckle 15, and the second buckle 2 is provided with a second ring buckle 22. Therefore, when the connecting buckle 100 is applied to the nursing bra, one end of the first buckle 1 is connected to the shoulder strap via the first ring buckle 15, and the second ring buckle 22 of the second buckle 2 is connected to the bra body, thereby forming a stable connection. In this design, by placing the entrance of the first sliding channel 12 of the first buckle body 1 on the outside, the second buckle body 2 is always engaged with the first buckle body 1 under the action of magnetic force and chest gravity when in the connected state, thereby improving the stability of the connected state. When unfastening, the second buckle body 2 must overcome the magnetic force and the pulling force of falling gravity to move upward.

[0059] This utility model embodiment also provides a one-handed unhooking method for the connecting buckle 100, including a first unhooking method;

[0060] The first unfastening method includes the following steps:

[0061] When the second buckle 2 is in the connected state, under the action of an external force applied by one finger of a single hand, the second buckle 2 moves against the magnetic force relative to the first buckle 1 along one side of the first sliding channel 12.

[0062] When the first buckle 1 is in the connected state, under the external force applied by the other finger of the hand, the first buckle 1 moves against the magnetic force relative to the second buckle 2 along the other side of the first sliding channel 12.

[0063] When the second buckle 2 moves out of the first sliding channel 12 of the first buckle 1, the second buckle 2 returns to the unbuckled state relative to the first buckle 1 from the connected state.

[0064] In some implementations, a second unfastening method is also included:

[0065] The second unfastening method includes the following steps:

[0066] When the second buckle 2 is in the connected state, under the external force applied by one finger of a single hand, the second buckle 2 overcomes the magnetic force and moves to the gap between the first buckle 1 and the second buckle 2, so that the hook 214 of the second buckle 2 is separated from the slot 112 of the first buckle 1.

[0067] When the finger presses against another finger of the hand, the first connecting end 213 of the second buckle body 2 rotates within the included angle space between the second connecting end 16 of the first buckle body 1 and the second connecting end 16 of the second buckle body 2, and rotates to fit against the second connecting end 16. When the second buckle body 2 rotates until the first protrusion 21 moves out of the first sliding channel 12, it returns to the unbuckled state.

[0068] In some embodiments, the step of overcoming magnetic force movement in the first and / or second unfastening methods specifically includes: a pulling movement that overcomes both magnetic force and the downward force of gravity. Specifically, when the pregnant woman is wearing the garment, the downward force of her breasts automatically pushes the sliding part of the second fastener 2 towards its end relative to the first sliding channel 12. This guides the second fastener 2 to self-lock relative to the first fastener 1 during the wearing state, further improving the stability of the fastening state. Unfastening is achieved by pushing the second fastener 2 outwards against both magnetic force and downward force using an external force.

[0069] The above embodiments are not an exhaustive list based on this utility model, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of this utility model are within the protection scope of this utility model.
