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 counter-push plate bolt retracts from the bolt hole and exits the locking ring; at the same time, under the lateral push of the counter-push pressing part from left to right, the counter-push magnet is aligned with the bolt hole and generates a repulsive force against the male buckle magnet, smoothly ejecting the lock head out of the bolt 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.

[0012] Furthermore, a reverse-push limiting insert is provided between the limiting baffle receiving groove and the limiting rib receiving groove, and a reverse-push limiting groove is provided between the reverse-push plate limiting rib and the reverse-push pressing limiting baffle; the reverse-push limiting groove is used to slidably engage the reverse-push limiting insert.

[0013] Furthermore, the edge of the lock head is a lock head guide slope, and the lower side of the push plate latch is provided with a male buckle guide slope, with the lock head guide slope and the male buckle guide slope guiding each other.

[0014] 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.

[0015] 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.

[0016] 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 bolt hole automatically align and engage. At this time, the lock head guide ramp pushes the male latch guide ramp of the bolt slider, the magnet fixing plate slides inside the reverse plate sliding cavity, and the bolt slider slides outside the bolt sliding cavity. This causes the reverse plate bolt of the bolt slider to retract from the bolt hole, allowing the lock head to smoothly enter the bolt hole. After the lock head is fully engaged, the reverse magnetic latch is reset under the action of the reverse plate spring, the magnet fixing plate slides outside the reverse plate sliding cavity, and the bolt slider slides inside the bolt sliding cavity. This causes the reverse plate bolt of the bolt slider to re-enter the bolt hole. The reverse reset limit baffle and the reverse limit block cooperate to limit the outward reset stroke of the reverse magnetic latch. The reverse plate bolt engages with the locking ring, completing the automatic locking.

[0017] When unlocking, press the reverse push press part, the magnet fixing plate slides to the inside of the reverse push plate sliding cavity, and the lock tongue sliding block slides to the outside of the lock tongue sliding cavity; the reverse push press limiting baffle and the reverse push limiting block cooperate with each other to limit the pressing stroke of the reverse push magnet suction plate inward; the reverse push plate lock tongue of the lock tongue sliding block is retracted from the lock tongue cavity, the reverse push plate lock tongue is separated from the locking ring, and the locking structure between the reverse push plate lock tongue and the locking ring is released. At the same time, the magnet fixing plate is pushed to move in the lock tongue hole, so that the suction magnet and the male buckle magnet in the lock head are mutually misaligned, the reverse push magnet and the male buckle magnet in the lock head are aligned, the magnetic force direction is changed from suction force to repulsion force, the lock head is smoothly pushed out of the lock tongue hole, and unlocking is completed.

[0018] After unlocking is completed, the reverse push press part is released, the reverse push reset limiting baffle and the reverse push limiting block cooperate with each other to limit the reset stroke of the reverse push magnet suction plate outward; the reverse push magnet suction plate is reset, and waits for the next buckling.

The reverse magnetic suction plate 13 can slide within the reverse sliding cavity 1112 on the left side of the female buckle cavity 111; the rear end of the reverse magnetic suction plate 13 is provided with a reverse pressing part 131; the reverse pressing part 131 extends forward to provide a magnet fixing plate 132, the magnet fixing plate 132 is provided with a reverse magnet embedding hole 1322 near the reverse pressing part 131, and a reverse magnet 13220 is embedded in the reverse magnet embedding hole 1322; the magnet fixing plate 132 is located away from the reverse pressing part 131. A magnet retaining hole 1321 is provided, and a magnet 13210 is embedded in the magnet retaining hole 1321. The magnet fixing plate 132 slides inside the latch hole 1111 under the drive of the push-press part 131. When the push-press part 131 is not driven by the pressing force, the magnet 13210 is aligned with the latch hole 1111. After the push-press part 131 is pressed from left to right, the magnet fixing plate 132 slides from left to right until the push-press magnet 13220 is aligned with the latch hole 1111. The fixing plate passes forward through the latch hole 1111 and is provided with a connecting part 135 in the latch sliding cavity 1113; a latch slider 136 is provided below the connecting part 135; a counter-push plate latch 1361 is provided on the left side of the latch slider 136; a male buckle guide slope 13611 is provided below the counter-push plate latch 1361; the latch slider 136 can slide in the latch sliding cavity 1113 on the right side of the female buckle cavity 111; 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 provided with a locking ring 221. A male buckle magnet 223 is embedded inside the lock head 222. Under the attraction of the male buckle magnet 223 and the attracting magnet 13210, the lock head 222 passes into the bolt hole 1111. The bolt slider 136 located in the bolt sliding cavity 1113 on the right side of the female buckle cavity 111 slides into the bolt hole 1111 and extends its push plate bolt 1361. The locking ring 221 can accommodate the extended push plate bolt 1361 to achieve the locking effect.

[0030] Furthermore, a reverse-push limiting insert 1323 is provided between the limiting baffle receiving groove 1324 and the limiting rib receiving groove 1325, and a reverse-push limiting groove 11112 is provided between the reverse-push plate limiting rib 11111 and the reverse-push pressing limiting baffle 11124; the reverse-push limiting groove 11112 is used to slidably engage the reverse-push limiting insert 1323.

[0031] Furthermore, the edge of the lock head 222 is a lock head guide slope 2221, and the lower side of the push plate latch 1361 is provided with a male buckle guide slope 13611, with the lock head guide slope 2221 and the male buckle guide slope 13611 guiding each other.

[0032] Furthermore, the male buckle plate 21 can be divided into a first male buckle plate 211 and a second male buckle plate 212 according to connection requirements. The first male buckle plate 211 can be combined with the second male buckle plate 212.

[0033] The assembly and use process of this invention is as follows: When assembling the female buckle cover 12 and the female buckle seat 11, align the four tenons 121 at the four corners of the female buckle cover 12 with the four mounting holes 1114 at the four corners of the female buckle cavity 111, press the female buckle cover 12 down, and the tenons 121 will fully enter the mounting holes 1114 along the guide slope 111411. Finally, the hooks 1211 on the tenons 121 and the snapping springs 11141 in the mounting holes 1114 will snap together to form a stable snapping structure, so that the female buckle cover 12 and the female buckle seat 11 are connected together.

[0034] When locked, the magnetic male latch 2 approaches the reverse female latch 1. Under the magnetic attraction of the magnetic magnet 13210 and the male latch magnet 223, the lock head 222 automatically aligns and engages with the latch hole 1111. At this time, the lock head guide slope 2221 pushes the male latch guide slope 13611 of the latch slider 136, the magnet fixing plate 132 slides inside the reverse push plate sliding cavity 1112, and the latch slider 136 slides outside the latch sliding cavity 1113. This causes the reverse push plate latch 1361 of the latch slider 136 to retract from the latch hole 1111, allowing the lock head 222 to smoothly enter the latch hole 1111. 111; After the lock head 222 is fully inserted, the reverse magnetic suction plate 13 is reset under the action of the reverse plate spring 11122, the magnet fixing plate 132 slides to the outside of the reverse plate sliding cavity 1112, and the lock tongue slider 136 slides to the inside of the lock tongue sliding cavity 1113; so that the reverse plate lock tongue 1361 of the lock tongue slider 136 re-enters the lock tongue hole 1111; the reverse reset limit baffle 11123 and the reverse limit block 133 cooperate with each other to limit the outward reset stroke of the reverse magnetic suction plate 13; the reverse plate lock tongue 1361 is engaged with the locking ring 221, and the automatic locking is completed.

[0035] When unlocking, pressing the reverse push pressing part 131 causes the magnet fixing plate 132 to slide inside the reverse push plate sliding cavity 1112, and the locking tongue slider 136 to slide outside the locking tongue sliding cavity 1113. The reverse push pressing limit baffle 11124 and the reverse push limit block 133 cooperate with each other to limit the inward pressing stroke of the reverse push magnetic suction plate 13. This causes the reverse push plate locking tongue 1361 of the locking tongue slider 136 to retract from the locking tongue hole 1111, and the reverse push plate locking tongue 1361 to disengage from the locking ring 221, thus releasing the locking structure between the reverse push plate locking tongue 1361 and the locking ring 221. At the same time, the magnet fixing plate 132 is pushed to move in the bolt hole 1111, causing the attracting magnet 13210 and the male snap magnet 223 in the lock head 222 to be misaligned, and the reverse magnet 13220 and the male snap magnet 223 in the lock head 222 to be aligned. The direction of the magnetic force changes from attraction to repulsion, and the lock head 222 is smoothly pushed out of the bolt hole 1111, completing the unlocking.

[0036] After unlocking, release the reverse push pressing part 131. The reverse push reset limit baffle 11123 and the reverse push limit block 133 cooperate with each other to limit the outward reset stroke of the reverse push magnetic suction plate 13; the reverse push magnetic suction plate 13 resets and waits for the next engagement.
