Description

Technical Field

[0001] This invention relates to safety buckles, and more particularly to a magnetic buckle. Background Technology

[0002] A safety buckle typically includes a female buckle 20 and a male buckle 10. The male buckle 10 has a locking part 11, and the female buckle 20 has a lock hole 21. The locking part 11 is inserted into the lock hole 21 to lock the male buckle 10 and the female buckle 20 together. By operating the unlocking mechanism, the male buckle 10 and the female buckle 20 can be separated from each other.

[0003] Typically, the locking structure on the female buckle 20 consists of a keyhole 21 and a locking part 231 whose position can change. When the locking part 231 extends into the keyhole 21, it acts as a lock, locking the mating part 11 within the keyhole 21, thereby connecting the male buckle 10 and the female buckle 20. When the locking part 231 exits the keyhole 21, the mating part 11 can freely enter and exit the keyhole 21 and exit from it, thus separating the male buckle 10 from the female buckle 20.

[0004] When the male buckle 10 and female buckle 20 are inserted, the locking part 11 usually presses against the locking part 231. The locking part 231 can only move forward after being pressed by the locking part 11, allowing it to continue. When the locking part 11 is fully inserted into the lock hole 21, the locking part 231 needs to automatically return to its original position to lock itself, thus achieving the locking connection between the male buckle 10 and female buckle 20. Therefore, during the insertion of the locking part 11 into the lock hole 21, the locking part 231, after being passively moved away, needs to automatically return to its original position to lock. Therefore, in existing safety buckles, the female buckle 20 must be equipped with an elastic part 254. The elasticity of the elastic part 254 provides an opportunity for the locking part 231 to move, allowing it to be pushed by the locking part 11, and the elasticity of the elastic part 254 enables the locking part 231 to lock automatically. For example, ZL201910147794.7. Summary of the Invention

[0005] The present invention aims to solve the above problems and provides a magnetic fastener that uses the magnetic force of a magnet to move and lock the locking part, thereby saving installation space.

[0006] To address the above problems, the present invention provides a magnetic fastener, comprising:

[0007] The female buckle has a locking hole, a locking part, and a second magnet.

[0008] The male buckle is provided with a locking part and a first magnet. The locking part can enter the lock hole and engage with the locking part. The first magnet and the second magnet attract each other to assist the male buckle and the female buckle in engaging along the connection direction.

[0009] The feature is that the female buckle is provided with a locking component and a linkage unlocking component, the locking component is provided with the locking part, and a third magnet is provided on the locking component; the linkage unlocking component is linked to the locking component.

[0010] When the locking part enters the lock hole, the third magnet interacts with the first magnet to drive the locking member to move, thereby engaging the locking part with the locking part. When the linkage unlocking member is operated, the linkage unlocking member drives the locking member to move, thereby disengaging the locking part from the locking part.

[0011] Furthermore, the linkage unlocking component includes:

[0012] The pusher part can cooperate with the locking member to push the locking member;

[0013] The force transmission part is offset to one side of the pushing part and connected to the pushing part;

[0014] The release operation part is connected to the force transmission part and is partially exposed outside the female buckle;

[0015] When the release operation part is operated in the first direction, the force transmission part drives the push part to move in the second direction, thereby pushing the locking member to move in the third direction, so that the locking member disengages from the locking part.

[0016] Wherein, the first direction, the second direction, and the third direction are perpendicular to the connection direction, and the second direction is transverse to the first direction and the third direction.

[0017] Furthermore, the force transmission part includes a first transmission part and a second transmission part, the first transmission part being inclined relative to the first direction and the second direction, and the second transmission part extending along the second direction.

[0018] Furthermore, the first transmission part is in the shape of a long rod, with its first end rotatably connected to the release operation part, the second end of the first transmission part rotatably connected to the first end of the second transmission part, and the second end of the second transmission part integrally formed or fixedly connected to the push part.

[0019] Furthermore, a first connecting hole is provided on the release operation part, and a second connecting hole is provided at the first end of the second transmission part. The first connecting hole and the second connecting hole are respectively provided with openings. The first end of the first transmission part is rotatably connected to the first connecting hole, and the second end of the first transmission part is rotatably connected to the second connecting hole.

[0020] Furthermore, the linkage unlocking component also includes an elastic part, which is connected between the release operation part and the push part or the release operation part and the force transmission part, and is used to drive the release operation part to reset.

[0021] Furthermore, the elastic part is integrally formed or fixedly connected with the release operation part and the push part.

[0022] Furthermore, the pushing part includes a first pushing part arranged in parallel intervals, the first pushing part extending along a second direction, and the end of the first pushing part away from the locking member is connected by a connecting part, the connecting part being connected to the force transmission part.

[0023] Furthermore, a first pushing slope is provided at the free end of the first pushing part, and a pushed slope is provided on the locking member. The first pushing slope and the pushed slope are inclined in the second direction and the third direction, respectively.

[0024] Furthermore, the pushing part also includes a second pushing part, which is disposed between the first pushing parts and parallel to and spaced apart from the first pushing parts, and one end of the second pushing part is connected to the connecting part;

[0025] A second pushing slope is provided on the free end of the second pushing part. The second pushing slope is inclined to the connection direction and the second direction. The second pushing part can be squeezed into the part where the locking part and the locking part are engaged, thereby increasing the distance between the male buckle and the female buckle.

[0026] Furthermore, the female buckle is provided with a limiting groove, the first limiting groove extends along a third direction, and the locking member is movably disposed in the limiting groove and can move along the third direction.

[0027] Furthermore, the linkage unlocking component includes a release operation part, two force transmission parts and two pushing parts, with the force transmission parts and pushing parts symmetrically arranged on both sides of the release operation part.

[0028] The beneficial contribution of this invention lies in its effective solution to the aforementioned problems. The magnetic fastener of this invention replaces the elastic component in the prior art with a third magnet. The interaction between the third magnet and the first magnet in the latch actuates the locking part, thereby simplifying the structure of the locking component, facilitating miniaturization, and expanding its application range. Furthermore, the linkage unlocking component of this invention features a novel structure, allowing for simultaneous unlocking of multiple locking parts. It is convenient to operate, functionally practical, and highly applicable, making it worthy of widespread promotion. Attached Figure Description

[0041] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0042] like Figures 1 to 8 As shown, the magnetic fastener of the present invention includes a male fastener 10 and a female fastener 20.

[0043] The shape of the female buckle 20 is not limited, but it has a lock hole 21, a locking part 231, and a second magnet 22. The shape of the male buckle 10 is not limited, but it has a locking part 11 and a first magnet 12. The locking part 11 can enter the lock hole 21 and engage with the locking part 231. When the locking part 11 engages with the locking part 231, the male buckle 10 and the female buckle 20 are connected together. When the locking part 11 disengages from the locking part 231, the locking part 11 can be withdrawn from the lock hole 21, at which point the male buckle 10 and the female buckle 20 can be separated. Through the cooperation of the locking part 23 and the locking part 11, the detachable connection of the male buckle 10 and the female buckle 20 can be achieved.

[0044] The first magnet 12 and the second magnet 22 attract each other. When the locking part 11 approaches the lock hole 21, the first magnet 12 and the second magnet 22 attract each other, allowing the locking part 11 to quickly enter the engagement position and engage with the locking part 231. The locking part 231 can be moved by operation, thereby disengaging it from the locking part 11 to separate the male buckle 10 and the female buckle 20. During the separation of the male buckle 10 and the female buckle 20, the first magnet 12 and the second magnet 22 attract each other, hindering the separation.

[0045] To drive the locking part 231 to move and engage with the matching locking part 11, a locking member 23 is provided in the female buckle 20, and the locking member 23 has the locking part 231. Furthermore, a third magnet 24 is provided on the locking member 23. The third magnet 24 moves together with the locking member 23.

[0046] Under the magnetic force of the second magnet 22 and the third magnet 24, the locking member 23 is in a first position. This first position can be an engaged position, an unlocked position, or a position between the engaged and unlocked positions. The first position is related to the magnitude of the magnetic force between the second magnet 22 and the third magnet 24.

[0047] Preferably, the first position is the engagement position, that is, the locking member 23 is in the position of engaging with the locking part 11 by default. When the locking part 11 enters the lock hole 21, the locking member 23 needs to be moved away from the first position first, and then moved back to the first position to engage with the locking part 11.

[0048] When the locking part 11 enters the lock hole 21, the third magnet 24 interacts with the first magnet 12, causing the locking member 23 to move and engage the locking part 231 with the locking part 11. Specifically, the third magnet 24 and the first magnet 12 initially repel each other magnetically, causing the locking part 231 to move away from the first position and away from the lock hole 21, thus facilitating the insertion of the locking part 11; as the locking part 11 is inserted, the position between the third magnet 24 and the first magnet 12 changes, and the magnetic repulsion between them changes into magnetic attraction, thereby attracting the locking part 231 back to the first position and engaging with the locking part 11.

[0049] To facilitate unlocking, the female latch 20 is movably equipped with a linkage unlocking component 25. The linkage unlocking component 25 is linked with the locking component 23. When the linkage unlocking component 25 is operated, it drives the locking component 23 to move, causing the locking part 231 to disengage from the locking part 11.

[0050] The locking part 11 is axial and protrudes from the male buckle 10. The cross-sectional shape of the locking part 11 is not limited; it can be cylindrical or non-cylindrical. A locking groove 111 is provided on the locking part 11 for engaging the locking part 231. The locking groove 111 is formed by a recess in the outer wall of the locking part 11. In some embodiments, the locking groove 111 is an annular groove, arranged circumferentially around the locking part 11. In this embodiment, the locking groove 111 is formed on a partial surface of the locking part 11, allowing the locking part 231 to enter.

[0051] When the locking part 231 enters the locking groove 111 in a direction transverse to the axial direction of the locking part 11, the locking part 231 engages with the locking part 11, at which time the locking part 11 cannot move along its axial direction. When the locking part 231 exits the locking groove 111 in a direction transverse to the axial direction of the locking part 11, the locking part 231 disengages from the locking part 11, and the locking part 11 can move along its axial direction, causing the male buckle 10 to separate from the female buckle 20.

[0052] Furthermore, to facilitate the insertion of the locking part 11 into the lock hole 21, a third pushing inclined surface 112 is provided at the end of the locking part 11. The third pushing inclined surface 112 is inclined relative to the axial direction of the locking part 11.

[0053] The locking element 23 is movably disposed within the female buckle 20. In this embodiment, the locking element 23 is a rigid structure that can move along a third direction X2. To enable the locking element 23 to move along the third direction X2, a limiting groove 26 is provided in the female buckle 20, extending along the third direction X2. The locking element 23 is movably disposed within the limiting groove 26 and can be limited to move along the third direction X2.

[0054] The number of locking elements 23 can be set as needed; there can be one or more. In this embodiment, two locking elements 23 are provided at each lock hole 21, and the two locking elements 23 are symmetrically arranged on both sides of the lock hole 21, and both can move along a third direction X2.

[0055] The linkage unlocking component 25 includes a pushing part 251, a force transmission part 252, and a release operation part 253. The pushing part 251 cooperates with the locking component 23 to push the locking component 23. The force transmission part 252 transmits the force from the release operation part 253 to the pushing part 251, causing the pushing part 251 to move. The force transmission part 252 is offset to one side of the pushing part 251 and connected to it. The release operation part 253 is operated by the user, is movably disposed within the female buckle 20, and partially protrudes outside the female buckle 20. The release operation part 253 is connected to the force transmission part 252. When the release operation part 253 is operated along the first direction X1, the push part 251 can be driven to move along the second direction Y by the force transmission part 252, thereby pushing the locking member 23 to move along the third direction X2, so that the locking member 23 disengages from the locking part 11.

[0056] Wherein, the first direction X1, the second direction Y, and the third direction X2 are perpendicular to the connection direction Z that connects the male buckle 10 and the female buckle 20. Furthermore, the second direction Y is transverse to the first direction X1 and the third direction X2, and preferably perpendicular to them. The first direction X1 and the third direction X2 are parallel or approximately parallel.

[0057] Furthermore, the force transmission unit 252 includes a first transmission unit 2521 and a second transmission unit 2522. The first transmission unit 2521 is inclined relative to the first direction X1 and the second direction Y, and the second transmission unit 2522 extends along the second direction Y.

[0058] In some embodiments, the first transmission part 2521, the second transmission part 2522, the release operation part 253, and the push part 251 are integrally formed or fixedly connected.

[0059] In this embodiment, the second transmission part 2522, the release operation part 253, and the pushing part 251 are integrally formed or fixedly connected, and are separately provided from the first transmission part 2521. In other words, the first transmission part 2521 is a separate component. The first transmission part 2521 is in the shape of a long rod, with its first end rotatably connected to the release operation part 253, and its second end rotatably connected to the first end of the second transmission part 2522. The second end of the second transmission part 2522 is integrally formed or fixedly connected to the pushing part 251. Thus, when the release operation unit 253 moves along the first direction X1, the position of the first end of the first transmission unit 2521 changes, and the distance between it and the second transmission unit 2522 will decrease, thereby pushing the second transmission unit 2522 to move in a direction away, that is, pushing the second transmission unit 2522 to move along the second direction Y toward the pusher 251, thereby pushing the pusher 251 to move along the second direction Y and get closer to the locking part 231, thereby pushing the locking part 231 to move and disengage from the locking part 11.

[0060] Furthermore, to achieve the rotational connection of the first transmission part 2521, a first connecting hole 2531 is provided on the unlocking operation part 253, and a second connecting hole 25221 is provided at the first end of the second transmission part 2522. The first connecting hole 2531 and the second connecting hole 25221 can be blind holes or through holes, and are circular holes. The axial directions of the first connecting hole 2531 and the second connecting hole 25221 are parallel to the connection direction Z.

[0061] To facilitate the installation of the first transmission part 2521, openings are provided on the first connecting hole 2531 and the second connecting hole 25221 respectively, so that the first transmission part 2521 can pass through.

[0062] Correspondingly, the first transmission part 2521 is in the shape of a long rod, which includes a long rod body part 25211 and columnar parts 25212 at both ends. The columnar parts 25212 at both ends of the first transmission part 2521 are respectively installed in the first connecting hole 2531 and the second connecting hole 25221, and can rotate.

[0063] The size of the opening should be greater than the lateral dimension of the main body 25211 within the opening, so that the first transmission part 2521 has a certain degree of freedom of movement.

[0064] Thus, when the release operation unit 253 moves along the first direction X1, the first transmission unit 2521 can be rotated to adapt to the angle between the first transmission unit 2521 and the first direction X1 and the second direction Y, thereby making the operation smoother.

[0065] To drive the release operation part 253 to reset, the linkage unlocking member 25 further includes an elastic part 254. The elastic part 254 is connected between the release operation part 253 and the pushing part 251, or between the release operation part 253 and the second transmission part 2522. When the release operation part 253 moves along the first direction X1, the elastic part 254 elastically deforms and always has a tendency to drive the release operation part 253 to reset.

[0066] The elastic part 254 is integrally formed or fixedly connected to the release operation part 253, the pushing part 251 or the second transmission part 2522. Preferably, the elastic part 254 is integrally formed with the release operation part 253 and the pushing part 251.

[0067] The elastic part 254 and the force transmission part 252 are both offset to one side of the pushing part 251.

[0068] Furthermore, the pushing portion 251 includes first pushing portions 2511 arranged in parallel intervals. The first pushing portions 2511 extend along the second direction Y and are rod-shaped or block-shaped.

[0069] The end of the first pushing part 2511 away from the locking member 23 is connected as a whole by the connecting part 2512, which is at least connected to the force transmission part 252. In this embodiment, the end of the connecting part 2512 is connected to the force transmission part 252, and the non-end is connected to the elastic part 254.

[0070] The free end of the first pushing part 2511 faces the locking member 23. A first pushing inclined surface 25111 is provided on the free end of the first pushing part 2511. Correspondingly, a pushed inclined surface 232 is provided on the locking member 23. The first pushing inclined surface 25111 and the pushed inclined surface 232 are inclined in the second direction Y and the third direction X2, and parallel to the connection direction Z. When the pushing part 251 moves along the second direction Y toward the locking member 23, the movement in the second direction Y can be converted into movement in the third direction X2 through the cooperation of the first pushing inclined surface 25111 and the pushed inclined surface 232, so that the locking member 23 moves away from the lock hole 21 along the third direction X2, thereby disengaging the locking part 231 from the locking part 11.

[0071] Furthermore, the pushing portion 251 further includes a second pushing portion 2513. The second pushing portion 2513 is disposed between the first pushing portions 2511 and is parallel and spaced apart from the first pushing portions 2511. The end of the second pushing portion 2513 away from the locking member 23 is connected to the connecting portion 2512. A second pushing inclined surface 25131 is provided on the free end of the second pushing portion 2513. The second pushing inclined surface 25131 is inclined to the connecting direction Z and the second direction Y, and parallel to the third direction X2. The second pushing inclined surface 25131 can cooperate with the third pushing inclined surface 112. When the pushing part 251 moves along the second direction Y toward the locking part 23, the second pushing inclined surface 25131 can be squeezed into the part where the locking part 11 and the locking part 231 are engaged. Specifically, it can cooperate with the third pushing inclined surface 112 to gradually increase the distance between the male buckle 10 and the female buckle 20, so as to separate the first magnet 12 and the second magnet 22, weaken the magnetic attraction between the first magnet 12 and the second magnet 22, so as to facilitate the separation of the male buckle 10 and the female buckle 20.

[0072] In some embodiments, the linkage unlocking member 25 includes a release operation part 253, a force transmission part 252, an elastic part 254, and a pushing part 251. Correspondingly, the female buckle 20 is provided with a locking hole 21, and one or more locking members 23 are provided at the locking hole 21 for engaging with the locking part 11 of a male buckle 10. In this embodiment, the release operation part 253 can be moved along a first direction X1 by pulling.

[0073] In some embodiments, the linkage unlocking member 25 includes a release operation part 253, two force transmission parts 252, two elastic parts 254, and two pushing parts 251. The force transmission parts 252, elastic parts 254, and pushing parts 251 are symmetrically arranged on both sides of the release operation part 253. Correspondingly, the female buckle 20 is symmetrically provided with two locking holes 21, and one or more locking members 23 are provided at each of the two locking holes 21, which can be used to engage with the two matching locking parts 11. The two matching locking parts 11 can be provided on one male buckle 10 or on two relatively independent male buckles 10. In this embodiment, the release operation part 253 can be moved along the first direction X1 by pulling.

[0074] In some embodiments, the linkage unlocking member 25 includes two release operation parts 253, four force transmission parts 252, four elastic parts 254, and four pushing parts 251. The release operation parts 253 are symmetrically arranged along a first direction X1. The release operation parts 253, force transmission parts 252, and pushing parts 251 are symmetrical in the first direction X1 and in the second direction Y. Correspondingly, the female buckle 20 is symmetrically provided with four locking holes 21, and one or more locking elements 23 are provided at each of the four locking holes 21, which can be used to engage with the four locking parts 11 simultaneously. When the release operation parts 253 are pulled outward simultaneously, the four pushing parts 251 simultaneously push the locking elements 23 to move and disengage from the four locking parts 11.

[0075] Furthermore, in order to constrain the second transmission part 2522 to move linearly along the second direction Y, a first limiting part 27 is provided in the female buckle 20. The first limiting part 27 is provided along the second direction Y, and the second transmission part 2522 abuts against the first limiting part 27. When the unlocking operation part 253 moves along the first direction X1, the second transmission part 2522 moves linearly along the first limiting part 27 along the second direction Y.

[0076] Furthermore, a second limiting part 28 is provided in the female buckle 20. The second limiting part 28 is spaced apart from the first limiting part 27, and a groove is formed between them for the force transmission part 252 and the elastic part 254 to move. The elastic part 254 abuts against the second limiting part 28.

[0077] Furthermore, the linkage unlocking component 25 and the locking component 23 are provided for activating the mechanism, and the female buckle 20 includes a housing 210 that is connected to it. Both the linkage unlocking component 25 and the locking component 23 are movably disposed within the housing 210. The lock hole 21 is fixedly provided on the housing 210.

[0078] Furthermore, to constrain the pushing part 251 to move linearly and to facilitate the placement of the second magnet 22, a magnet frame 29 is provided in the female buckle 20. The position of the magnet frame 29 corresponds to the position of the lock hole 21. The magnet frame 29 is fixedly connected to or integrally formed with the housing 210, and protrudes into the interior of the housing 210. A magnet groove 291 is provided on the side of the magnet frame 29 away from the lock hole 21, and the second magnet 22 is fixedly embedded in the magnet groove 291. An insertion hole 292 communicating with the lock hole 21 is provided on the side of the magnet frame 29, and the free ends of the first pushing part 2511 and the second pushing part 2513 can enter and exit the insertion hole 292. By providing constraint through the sidewall of the insertion hole 292, the pushing part 251 can be ensured to move linearly.

[0079] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
