Description

Technical Field

[0001] This invention relates to the field of fasteners, and more specifically to a magnetic fastener. Background Technology

[0002] US Patent No. 2615227 combines magnets with necklace clasps, using magnetic attraction to guide the two ends of the clasp to automatically snap together, forming the basic configuration of a magnetic clasp. For nearly eighty years, magnetic clasps have been associated with luxury, maintaining a unique sense of superiority over ordinary clasps. In recent years, people have begun to provide different solutions for how to separate the automatically engaging male and female clasps in magnetic clasps. CN109662399B discloses an invention patent entitled "Magnetic Hook and Loop," which uses "opposite pressing parts, with the unlocking part moving towards the part where the latch and hook and loop assembly are combined, thus separating the part where the latch and hook and loop assembly are combined, reducing the attraction between the first and second magnets, and facilitating the separation of the hook and loop assembly." This solution draws on the most primitive human concept of "using a wedge to extract stone," inserting a wedge into the engagement point of the male and female clasps of the magnetic clasp to separate the magnetic clasp. CN223183052U discloses a five-point magnetic reverse push safety buckle that conceptually integrates magnetic attraction and reverse push. However, this solution uses a single-sided push method to unlock. During operation, the thumb or index finger is used to push the unlocking plate, and two other fingers are also required to hold the buckle, which is inconvenient to operate.

[0003] To address the aforementioned shortcomings, this invention provides a reverse-push magnetic buckle that combines rapid magnetic alignment, dual locking via magnetic attraction and mechanical locking, convenient unlocking, and high security. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a reverse magnetic buckle. This buckle automatically aligns with magnetic attraction, locks upon insertion, unlocks with a single push, operates smoothly, and is securely assembled.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reverse-push magnetic buckle includes a reverse-push female buckle and a magnetic male buckle, wherein the reverse-push female buckle and the magnetic male buckle are detachably connected by magnetic attraction. The reverse push female buckle includes a female buckle seat, a female buckle cover, a reverse push magnetic suction plate, and a locking tongue slide plate. The reverse push magnetic suction plate and the locking tongue slide plate are installed inside the space formed by the female buckle seat and the female buckle cover.

The female buckle seat has a female buckle cavity inside; a locking tongue hole is provided at the center of the female buckle cavity, and reversing gears are provided on both sides of the locking tongue hole; a reverse push plate sliding cavity is provided on the left side of the female buckle cavity, and a locking tongue sliding cavity is provided on the right side of the female buckle cavity; The reverse magnetic suction plate can slide within the reverse sliding cavity on the left side of the female buckle cavity; the rear end of the reverse magnetic suction plate is provided with a reverse pressing part; the reverse pressing part extends forward to provide a magnet fixing plate, the magnet fixing plate is provided with a reverse magnet fixing hole near the reverse pressing part, and a reverse magnet is fixed in the reverse magnet fixing hole; the magnet fixing plate is provided with an attraction magnet fixing hole away from the reverse pressing part, and an attraction magnet is fixed in the attraction magnet fixing hole; the magnet fixing plate slides inside the latch hole under the drive of the reverse pressing part, and when the reverse pressing part is not driven by pressing force, the attraction magnet is aligned with the latch hole; When the reverse push pressing part is pressed from left to right, the magnet fixing plate slides from left to right until the reverse push magnet is aligned with the latch hole; the magnet fixing plate passes forward through the latch hole and has a connecting block in the latch sliding cavity; a latch slider is provided below the connecting block, a reverse push plate latch is provided on the left side of the latch slider, and a male buckle guide slope is provided below the reverse push plate latch; the latch slider can slide in the latch sliding cavity on the right side of the female buckle cavity; the magnet fixing plate extends outward and downward on both sides to form a latch slide receiving groove, and a reverse push plate rack is provided on both sides of the latch slide receiving groove, with the rack direction facing the inside of the female buckle cavity; The locking tongue slide is located in the locking tongue slide receiving groove below the magnet fixing plate and can slide in the reverse push plate sliding cavity; the rear end of the locking tongue slide is provided with a slide base; the center of the slide base has a slide locking tongue protruding forward; the two sides of the slide base extend forward with slide racks, the racks facing the outside of the female buckle cavity; The reverse push plate rack meshes with the outer side of the reversing gear, and the slide plate rack meshes with the inner side of the reversing gear; through the meshing of the three, the reverse push magnetic suction plate and the locking tongue slide plate are reversed; the reverse push magnetic suction plate moves towards the inner side of the female buckle cavity, the reverse push plate rack drives the reversing gear to rotate, and thus drives the locking tongue slide plate to move outward from the locking tongue hole. The magnetic male buckle includes a male buckle plate and a male buckle protruding from the male buckle plate; the top of the male buckle is a lock head, and a locking ring is provided at the bottom of the lock head. A male buckle magnet is embedded inside the lock head; under the attraction of the male buckle magnet and the attracting magnet, the lock head passes into the bolt hole, and the push plate bolt located in the right bolt sliding cavity of the female buckle cavity and the slide plate bolt located in the left push plate sliding cavity of the female buckle cavity slide out into the bolt hole. The locking ring can accommodate the extended push plate bolt and slide plate bolt to achieve engagement; a pressing force is applied to the push pressing part in the direction of the inner side of the female buckle cavity to push... The magnet fixing plate slides towards the inside of the push plate sliding cavity, and the latch slider moves towards the outside of the latch sliding cavity, causing the push plate latch to retract from the latch hole. Simultaneously, due to the meshing relationship between the push plate rack, the reversing gear, and the slide rack, the latch slide moves from the latch hole towards the push plate sliding cavity, driving the slide latch to exit from the latch hole. Both the push plate latch and the slide latch exit the locking ring. Furthermore, under the lateral push from left to right by the push pressing part, the push magnet aligns with the latch hole, generating a repulsive force on the male latch magnet, and smoothly ejects the lock head from the latch hole.

[0006] Furthermore, each side of the female buckle cavity is provided with a mounting buckle hole, and a fastening spring is provided in the mounting buckle hole. The fastening spring is provided with a guide slope on its side. Each side of the female buckle cover is provided with a fastening tenon at the position corresponding to the mounting buckle hole. The lower end of the fastening tenon is provided with a fastening hook that fastens with the fastening spring in the mounting buckle hole.

[0007] Furthermore, the female buckle seat has a first webbing groove on its outer side; the male buckle plate has a second webbing groove on its side.

[0008] Furthermore, a counter-push plate spring slot is provided on the outer side of the center of the locking tongue sliding cavity; a counter-push plate spring is provided, one end of which is locked in the counter-push plate spring slot, and the other end abuts against the surface of the locking tongue slider of the counter-push magnetic suction plate facing the outer side of the female buckle cavity. Under the elastic prestress of the counter-push plate spring, the counter-push pressing part abuts against the counter-push plate sliding cavity away from the center end.

[0009] Furthermore, a reverse push limiting block is provided at the connection between the reverse push pressing part and the magnet fixing plate; a reverse push reset limiting baffle is provided on the outside of the reverse push plate sliding cavity; the reverse push reset limiting baffle and the reverse push limiting block cooperate with each other to limit the outward reset stroke of the reverse push magnetic suction plate.

[0010] Furthermore, a reverse push limiting block is provided at the connection between the reverse push pressing part and the magnet fixing plate; a reverse push pressing limiting baffle is provided on the inner side of the reverse push plate sliding cavity; the reverse push pressing limiting baffle and the reverse push limiting block cooperate with each other to limit the inward pressing stroke of the reverse push magnetic suction plate.

[0011] Furthermore, the magnet fixing plate is provided with limiting rib receiving grooves on both sides; a reverse push plate limiting rib is provided between the locking tongue hole and the reversing gear, and the reverse push plate limiting rib can slide in the limiting rib receiving groove to limit the longitudinal position of the magnet fixing plate in the reverse push plate sliding cavity.

[0012] Furthermore, a locking tongue slide plate limiting groove is provided between the push plate limiting rib and the reversing gear to limit the longitudinal position of the locking tongue slide plate in the push plate sliding cavity; the rack of the slide plate gear meshes with the reversing gear in the locking tongue slide plate limiting groove on the outside of the female buckle cavity.

[0013] Furthermore, a sliding plate limiting pressure plate is provided below the magnet fixing plate. The limiting pressure plate abuts against the upper surface of the locking tongue sliding plate, limiting the vertical position of the locking tongue sliding plate in the sliding cavity of the reverse push plate.

[0014] Furthermore, the edge of the lock head is a lock head guide slope, the lower side of the push plate lock tongue is provided with a push plate lock tongue guide slope, and the lower side of the slide plate lock tongue is provided with a slide plate lock tongue guide slope. The lock head guide slope, the push plate lock tongue guide slope, and the slide plate lock tongue guide slope form a guide to guide the lock head into the lock tongue hole.

[0015] Furthermore, the male buckle plate can be divided into a first male buckle plate and a second male buckle plate according to connection requirements, and the first male buckle plate can be combined with the second male buckle plate.

[0016] The assembly and use process of this invention is as follows: When assembling the female buckle cover and the female buckle seat, align the four tenons at the four corners of the female buckle cover with the four mounting holes at the four corners of the female buckle cavity, press the female buckle cover down, and the tenons will fully enter the mounting holes along the guide slope. Finally, the hooks on the tenons will engage with the snap-fit ​​springs in the mounting holes to form a stable snap-fit ​​structure, connecting the female buckle cover and the female buckle seat together.

[0017] During locking, the magnetic male latch approaches the reverse female latch. Under the magnetic attraction of the magnetic magnet and the male latch magnet, the lock head and the latch hole automatically align and engage. At this time, the lock head guide ramp pushes the reverse latch guide ramp of the reverse push plate latch and the sliding plate latch guide ramp of the sliding plate latch. The magnet fixing plate slides towards the inside of the reverse push plate sliding cavity, and the latch slider slides towards the outside of the latch sliding cavity, causing the reverse push plate latch of the latch slider to retract from the latch hole. Simultaneously, due to the meshing relationship between the reverse push plate rack, the reversing gear, and the sliding plate rack, the latch sliding plate slides towards the outside of the reverse push plate sliding cavity, driving the sliding plate latch to retract from the latch hole, allowing the lock head to smoothly enter the latch hole. After the lock head is fully engaged, the reverse push magnetic plate resets under the action of the reverse push plate spring, the magnet fixing plate slides towards the outside of the reverse push plate sliding cavity, and the latch slider slides towards the inside of the latch sliding cavity. The locking tongue slides into the sliding cavity of the reverse push plate, causing the reverse push plate locking tongue and the sliding plate locking tongue to re-enter the locking tongue hole; the reverse push reset limit baffle and the reverse push limit block cooperate with each other to limit the outward reset stroke of the reverse push magnetic suction plate; the reverse push plate locking tongue and the sliding plate locking tongue engage with the locking ring to complete the automatic locking.

[0018] During unlocking, pressing the reverse push button causes the magnet fixing plate to slide inwards towards the reverse push plate sliding cavity, while the latch slider slides outwards towards the latch sliding cavity. The latch slide plate slides inwards towards the reverse push plate sliding cavity; the reverse push press limit baffle and the reverse push limit block cooperate to restrict the inward pressing stroke of the reverse push magnetic plate; this causes the reverse push plate latch and the slide plate latch to retract from the latch hole, disengaging them from the locking ring and releasing the locking structure between the reverse push plate latch, the slide plate latch, and the locking ring. Simultaneously, the magnet fixing plate is pushed to move within the latch hole, causing the attracting magnet to misalign with the male snap magnet in the lock head, and the reverse push magnet to align with the male snap magnet in the lock head. The magnetic force changes from attraction to repulsion, smoothly pushing the lock head out of the latch hole, completing the unlocking process.

[0019] After unlocking, release the reverse push pressing part. The reverse push reset limit baffle and the reverse push limit block cooperate with each other to limit the outward reset stroke of the reverse push magnetic plate; the reverse push magnetic plate resets and waits for the next latching.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] like Figures 1-10 As shown, the present invention provides a reverse magnetic buckle, including a reverse female buckle 1 and a magnetic male buckle 2, wherein the reverse female buckle 1 and the magnetic male buckle 2 are detachably connected by magnetic attraction.

[0025] The reverse push female buckle 1 includes a female buckle seat 11, a female buckle cover 12, a reverse push magnetic suction plate 13, and a locking tongue slide plate 14. The reverse push magnetic suction plate 13 and the locking tongue slide plate 14 are assembled in the internal space formed by the female buckle seat 11 and the female buckle cover 12. The reverse push magnetic suction plate 13 and the locking tongue slide plate 14 can slide relative to each other, thereby realizing the unlocking and separation between the reverse push female buckle 1 and the magnetic male buckle 2.

[0026] The female buckle seat 11 is internally formed into a female buckle cavity 111; a locking tongue hole 1111 is opened in the center of the female buckle cavity 111, and a reversing gear 11112 is installed on both the left and right sides of the locking tongue hole 1111; a reverse push plate sliding cavity 1112 is provided on the left side of the female buckle cavity 111, and a locking tongue sliding cavity 1113 is provided on the right side of the female buckle cavity 111.

[0027] The reverse magnetic suction plate 13 is installed inside the reverse sliding cavity 1112 on the left side of the female buckle cavity 111 and can slide laterally along the cavity. The rear end of the reverse magnetic suction plate 13 is integrally formed with a reverse pressing part 131. A magnet fixing plate 132 is provided extending forward from the reverse pressing part 131. A reverse magnet fixing hole 1322 is opened on the magnet fixing plate 132 near the reverse pressing part 131, and a reverse magnet 13220 is fixedly installed in the reverse magnet fixing hole 1322. An attraction magnet fixing hole 1321 is opened on the magnet fixing plate 132 away from the reverse pressing part 131, and an attraction magnet 13210 is fixedly installed in the attraction magnet fixing hole 1321. When the push-back pressing part 131 is not subjected to external pressing force, the magnet fixing plate 132 remains in the initial position, and the magnet 13210 is directly opposite the latch hole 1111. When a pressing force from left to right is applied to the push-back pressing part 131, the magnet fixing plate 132 slides to the right until the push-back magnet 13220 is aligned with the latch hole 1111. The magnet fixing plate 132 passes forward through the latch hole 1111, and a connecting block 134 is provided in the latch sliding cavity 1113. The latch slider 1341 is integrally formed below the connecting block 134. A push-back plate latch 13411 is provided on the left side of the latch slider 13411. A male buckle guide slope 2221 is provided on the lower side of the push-back plate latch 13411. The latch slider 1341 can slide in the latch sliding cavity 1113 on the right side of the female buckle cavity 111. The magnet fixing plate 132 extends outward on both sides, and a locking tongue slide receiving groove 1323 is formed below it; the locking tongue slide receiving groove 1323 is provided on both sides of the locking tongue slide receiving groove 1323, and the teeth of the locking tongue slide 1325 face the inside of the female buckle cavity 111.

[0028] The locking tongue slide plate 14 is arranged in the locking tongue slide plate receiving groove 1323 below the magnet fixing plate 132, and the locking tongue slide plate 14 can slide inside the reverse push plate sliding cavity 1112; the rear end of the locking tongue slide plate 14 is the slide plate base 141; the center of the slide plate base 141 protrudes forward to form the slide plate locking tongue 1412; the left and right sides of the slide plate base 141 extend forward to provide slide plate racks 1411, and the teeth of the slide plate racks 1411 face the outside of the female buckle cavity 111.

[0029] The push plate rack 1325 meshes with the outer side of the reversing gear 11112, and the slide plate rack 1411 meshes with the inner side of the reversing gear 11112. Relying on the transmission of the reversing gear 11112, the push magnetic suction plate 13 and the locking tongue slide plate 14 achieve reverse linkage sliding: when the push magnetic suction plate 13 moves towards the inner side of the center of the female buckle cavity 111, the push plate rack 1325 drives the reversing gear 11112 to rotate, and the reversing gear 11112 further drives the locking tongue slide plate 14 to move away from the locking tongue hole 1111.

[0030] The magnetic male buckle 2 includes a male buckle plate 21 and a male buckle 22 protruding from the male buckle plate 21. The top of the male buckle 22 is a lock head 222, and the lower part of the lock head 222 is formed with a locking ring 221. The lock head 222 is fitted with a male buckle magnet 223. When engaged, under the magnetic attraction between the male buckle magnet 223 and the attracting magnet 13210, the lock head 222 is inserted into the bolt hole 1111. The push plate bolt 13411 located in the bolt sliding cavity 1113 and the slide plate bolt 1412 located in the push plate sliding cavity 1112 extend together toward the center of the bolt hole 1111 and into the locking ring 221, completing the mechanical locking engagement.

[0031] Unlocking process: Press the reverse push pressing part 131 inside the female buckle cavity 111, which drives the magnet fixing plate 132 to slide inside the reverse push plate sliding cavity 1112. The locking tongue slider 1341 moves to the outside of the locking tongue sliding cavity 1113, and the reverse push plate locking tongue 13411 retracts from the locking tongue hole 1111. At the same time, through the gear transmission of the reverse push plate rack 1325, the reversing gear 11112, and the sliding plate rack 1411, the locking tongue sliding plate 14 slides to the outside of the reverse push plate sliding cavity 1112, and the sliding plate locking tongue 1412 simultaneously exits the locking tongue hole 1111. Both the reverse push plate locking tongue 13411 and the sliding plate locking tongue 1412 are completely disengaged from the locking ring 221, and the mechanical lock is released. After being pressed into place, the reverse magnet 13220 is aligned with the bolt hole 1111. The reverse magnet 13220 generates a magnetic repulsion force on the male latch magnet 223, which smoothly ejects the lock head 222 outward from the bolt hole 1111, achieving complete separation of the male and female latches.

[0032] Furthermore, each side of the female buckle cavity 111 is provided with a mounting buckle hole 1114, and a fastening spring piece 11141 is provided in the mounting buckle hole 1114. A guide slope 111411 is provided on the side of the fastening spring piece 11141. Each side of the female buckle cover 12 is provided with a fastening tenon 121 corresponding to the mounting buckle hole 1114. A hook 1211 is provided at the lower end of the fastening tenon 121. The hook 1211 and the fastening spring piece 11141 inside the mounting buckle hole 1114 engage with each other to achieve quick assembly of the female buckle seat 11 and the female buckle cover 12.

[0033] Furthermore, a first webbing groove 112 is provided on the outer side of the female buckle seat 11; a second webbing groove 23 is provided on the side of the male buckle plate 21. The webbing can be inserted into the first webbing groove 112 and the second webbing groove 23 to sew and fix the magnetic buckle to the strap of a backpack, seat belt, etc.

[0034] Furthermore, a counter-push plate spring slot 11131 is provided near the center of the outer side of the locking tongue sliding cavity 1113; a counter-push plate spring 11132 is configured, with one end of the counter-push plate spring 11132 engaging in the counter-push plate spring slot 11131, and the other end abutting against the surface of the locking tongue slider 1341 of the counter-push magnetic suction plate 13 facing the outer side of the female buckle cavity 111. Relying on the pre-tightening elastic force of the counter-push plate spring 11132, in the absence of external pressure, the counter-push pressing part 131 remains against the end of the counter-push plate sliding cavity 1112 away from the center of the cavity, which is the initial position of engagement.

[0035] Furthermore, a push-back limiting block 133 is provided at the position where the push-back pressing part 131 connects to the magnet fixing plate 132; a push-back reset limiting baffle 11121 is provided on the outer side of the push-back plate sliding cavity 1112, and the push-back reset limiting baffle 11121 cooperates with the push-back limiting block 133 to limit the maximum stroke of the push-back magnetic suction plate 13 to reset outward, preventing the push-back magnetic suction plate 13 from dislodging from the cavity. A push-back pressing limiting baffle 11122 is also provided on the inner side of the push-back plate sliding cavity 1112, and the push-back pressing limiting baffle 11122 also cooperates with the push-back limiting block 133 to limit the maximum displacement when pressing inward, avoiding excessive pressing and damage to the internal gears and magnet assembly.

[0036] Furthermore, limiting rib receiving grooves 13231 are provided on both sides of the magnet fixing plate 132; a push plate limiting rib 11111 is provided between the locking tongue hole 1111 and the reversing gear 11112. The push plate limiting rib 11111 can slide inside the limiting rib receiving groove 13231 to limit the vertical longitudinal displacement of the magnet fixing plate 132 in the push plate sliding cavity 1112, so as to ensure smooth sliding without deviation.

[0037] Furthermore, a locking tongue slide plate limiting groove 11113 is provided between the thrust plate limiting rib 11111 and the reversing gear 11112. The locking tongue slide plate limiting groove 11113 constrains the longitudinal position of the locking tongue slide plate 14 in the thrust plate sliding cavity 1112. The teeth of the slide plate rack 1411 face the outside of the female buckle cavity 111 and mesh with the reversing gear 11112 in the locking tongue slide plate limiting groove 11113.

[0038] Furthermore, an integrally formed sliding plate limiting pressure plate 1324 is formed below the magnet fixing plate 132. The lower surface of the sliding plate limiting pressure plate 1324 is in contact with the upper surface of the locking tongue sliding plate 14 to restrict the locking tongue sliding plate 14 from moving up and down.

[0039] Furthermore, a lock head guide slope is provided on the edge of the lock head 222, a push-pull lock tongue guide slope 134111 is provided on the lower side of the push plate lock tongue 134111, and a slide lock tongue guide slope 14121 is provided on the lower side of the slide lock tongue 1412. The lock head guide slope, the push-pull lock tongue guide slope 134111, and the slide lock tongue guide slope 14121 cooperate with each other to form an inlet slope. When the male buckle 22 is pressed down, it pushes the lock tongue to move to both sides, so that the lock head 222 can smoothly enter the lock tongue hole 1111 to complete the engagement.

[0040] Furthermore, the male buckle plate 21 can be split into a first male buckle plate 211 and a second male buckle plate 212 according to usage requirements. The first male buckle plate 211 and the second male buckle plate 212 can be spliced ​​and combined to adapt to different webbing connection structures.
