Description

Technical Field

[0001] This invention relates to the field of fastener technology, and more specifically to a magnetic fastener for use on webbing, clothing, bags or protective equipment. Background Technology

[0002] Currently, most conventional fasteners on the market are purely mechanical snap-fit ​​structures, which have problems such as difficulty in fastening, inaccurate alignment, inconvenience in one-handed operation, and easy loosening. Some magnetic fasteners rely solely on magnetic attraction and lack a mechanical locking structure, resulting in insufficient connection strength. They are prone to accidental opening under stress or vibration, leading to poor safety and stability.

[0003] For example, patent document CN114027592A discloses a pull-to-unlock fastener device, including a lockable first connecting module and a second connecting module. The first connecting module has a protruding latch, and the second connecting module has a fixing hole for the latch to freely enter and exit, as well as an unlocking element and a locking part. The locking principle of this fastener device is that when the first and second connecting modules are close together, they attract each other through a magnetic device, allowing the latch to quickly insert into the keyhole, after which the locking part locks the latch. This fastener device has a relatively simple locking method, relying solely on the locking part to restrict the movement of the latch, which may lead to insufficient connection strength and easy accidental opening. During unlocking, pulling the unlocking element outward causes the locking part to move along the pulling direction, releasing the latch and separating the first and second connecting modules. This unlocking method is simple, but it is prone to misinterpretation, resulting in insufficient security. The elastic part on the unlocking component can assist in locking and unlocking the first and second connecting modules. However, the elastic part mainly relies on elastic contraction, and long-term use can easily cause elastic decay, affecting the locking and unlocking effect and resulting in insufficient safety performance.

[0004] To address the aforementioned shortcomings, this invention provides a magnetic connector that combines the functions of rapid magnetic alignment and mechanical locking. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a magnetic connector buckle that is structurally stable, quick to snap on, reliable to lock, and easy to unlock, achieving quick snap-on with one hand, strong magnetic positioning, mechanical locking to prevent detachment, and dual unlocking by pressing / pulling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: the present invention provides a magnetic connector buckle, including a magnetic base and a magnetic snap fastener, wherein the magnetic base and the magnetic snap fastener are detachably connected by magnetic attraction.

[0007] The magnetic base has a snap-fit ​​base plate at its bottom, with a snap-fit ​​boss in the middle. A base magnet groove is recessed at the front end of the snap-fit ​​boss, and a base magnet is embedded in the groove. A locking seat protrudes from the rear end of the snap-fit ​​boss. A locking hole is located on the lower front side of the locking seat, with an inclined locking guide surface above the hole. An opening / closing ramp is located on the upper rear side of the locking seat, and a snap-fit ​​reinforcing surface is located on the lower rear side. A first webbing groove is located at the rear end of the snap-fit ​​base plate for connecting webbing. Base reinforcing ribs are provided on the sides of the first webbing groove and the snap-fit ​​base plate to enhance the structural strength of the base. A snap-fit ​​groove is also located in the middle of the magnetic base, between the snap-fit ​​boss and the first webbing groove.

[0008] The magnetic hook and loop fastener includes a fastener base and a locking plate that can slide within the fastener base. The fastener base has a locking cavity inside, and a fastening ring corresponding to the position of the fastening boss is located at the lower part of the locking cavity, engaging with the fastening boss. A locking limiting rib is provided on the side of the locking cavity to restrict the movement of the locking plate. A second webbing groove is provided at the rear end of the fastener base, and a webbing adjusting rod is provided in the middle of the second webbing groove. Fastener reinforcing ribs are provided on both sides of the second webbing groove and the fastening ring, and a fastening reinforcing plate is provided at the front end of the fastening ring, which cooperates with the fastening reinforcing surface to ensure connection strength and structural stability. The locking plate is equipped with an unlocking drive mechanism for unlocking. The unlocking drive mechanism can be a traction hole at the rear end of the locking plate or a pressing plate at the front end of the locking plate, used for traction unlocking and pressing unlocking respectively. A latch magnet groove is opened in the middle of the locking plate, and a latch magnet is embedded in the latch magnet groove to form an attraction with the base magnet in the magnetic base. A locking hole is provided at the front of the locking plate, and a latch tongue protrudes from the rear side of the locking hole. A latching guide surface is provided on the lower side of the latch tongue. A guide rib is provided below the front side of the locking hole. Assembly guide surfaces are provided on both sides of the rear end of the locking plate. A locking limiting groove corresponding to the locking limiting rib on the buckle seat is provided at the front of the assembly guide surface to limit the locking plate to slide smoothly along a set trajectory.

[0009] Work process: When assembling the magnetic hook and loop fastener, align the assembly guide surface at the rear end of the locking plate with the front sides of the locking cavity, and insert it into the locking cavity under the guidance of the assembly guide surface until the locking limit rib is engaged in the locking limit groove.

[0010] During engagement, the magnetic base and magnetic latch are brought close together, and automatically aligned under magnetic force. The latch ring engages with the latching boss, and the front end of the magnetic latch engages into the latching groove. The latching reinforcement plate at the front end of the latch ring abuts against the latching reinforcement surface on the rear side of the locking seat to ensure the strength of the engagement structure. During engagement, the latching guide surface on the lower side of the latch tongue and the guide rib below the front side of the locking hole correspond to the locking guide surface on the front side of the locking seat and the opening and closing slope on the rear side of the locking seat to form a guiding fit, guiding the latch tongue into the locking hole. In particular, during the engagement process, under the mutual attraction of the base magnet and the latch magnet, before the two magnets are attracted, the latching guide surface moves the latch tongue longitudinally along the locking guide surface to below the locking guide surface, and then guides the latch tongue laterally until the latch tongue is engaged into the locking hole. At the same time, the two magnets are fully attracted, completing the locking.

[0011] During unlocking, press the pressing plate or pull the traction hole. The locking plate slides laterally backward within the locking cavity, causing the latch to retract from the locking engagement hole. The guide rib below the front of the locking hole slides obliquely upward along the opening and closing slope on the rear side of the locking seat, driving the front end of the locking plate upward. This overcomes the mutual attraction between the base magnet and the latch magnet, separating the locking plate from the latching boss. Simultaneously, it causes the latch ring at the bottom of the latch seat to disengage from the latching boss, thus releasing the lock and separating the magnetic latch from the magnetic base. During unlocking, the lateral sliding range of the locking plate within the locking cavity is limited by the sliding range of the locking limiting rib within the locking limiting groove.

[0012] The beneficial effects of this invention are as follows: 1. The magnetic attraction formed by the base magnet and the snap magnet allows for quick alignment and automatic snapping without the need for precise alignment, and can be completed with one hand; 2. The magnetic lock formed by the base magnet and the buckle magnet, combined with the mechanical lock formed by the locking seat and the locking tongue, provides a double lock, which has high connection strength and is not easy to accidentally loosen; 3. The fastening reinforcement surface and fastening reinforcement plate are set to enhance the fastening strength, and the magnetic base and magnetic fastener are both equipped with reinforcement ribs for high durability; 4. Flexible unlocking methods, supporting both pressing the pressure plate and using the traction hole for unlocking, making it suitable for a wider range of scenarios; 5. The guide structure is well-designed, with the opening and closing ramp, locking guide surface, snap-fit ​​guide surface, and guide ribs working together to make snap-fitting and unlocking smoother.

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] like Figure 1-6 As shown, the present invention provides a magnetic connector buckle, including a magnetic base 1 and a magnetic snap fastener 2, wherein the magnetic base 1 and the magnetic snap fastener 2 are detachably connected by magnetic attraction.

[0017] The magnetic base 1 has a snap-fit ​​base plate 11 at its bottom, with a snap-fit ​​boss 12 in the middle of the snap-fit ​​base plate 11. A base magnet groove 121 is recessed at the front end of the snap-fit ​​boss 12, and a base magnet 1210 is embedded in the base magnet groove 121. A locking seat 122 protrudes from the rear end of the snap-fit ​​boss 12. A locking insertion hole 1221 is provided on the lower front side of the locking seat 122, and an inclined locking guide surface 1223 is provided above the locking insertion hole 1221. An opening and closing inclined surface 1222 is provided on the upper rear side of the locking seat 122, and a snap-fit ​​reinforcing surface 1224 is provided on the lower rear side. A first webbing groove 13 is provided at the rear end of the snap-fit ​​base plate 11 for connecting webbing. Base reinforcing ribs 14 are provided on the sides of the first webbing groove 13 and the snap-fit ​​base plate 11 to enhance the structural strength of the base. A snap-fit ​​groove 15 is also provided in the middle of the magnetic base 1, located between the snap-fit ​​boss 12 and the first webbing groove 13.

[0018] The magnetic hook and loop fastener 2 includes a fastener base 21 and a locking plate 22 that can slide within the fastener base 21. The fastener base 21 has a locking cavity 211 inside, and a fastening ring 212 corresponding to the position of the fastening boss 12 is provided at the lower part of the locking cavity 211 to fasten with the fastening boss 12. A locking limiting rib 2111 is provided on the side of the locking cavity 211 to limit the movement stroke of the locking plate 22. A second webbing groove 213 is provided at the rear end of the fastener base 21, and a webbing adjusting rod 2131 is provided in the middle of the second webbing groove 213. Fastener reinforcing ribs 214 are provided on both sides of the second webbing groove 213 and the fastening ring 212, and a fastening reinforcing plate 215 is provided at the front end of the fastening ring 212, which cooperates with the fastening reinforcing surface 1224 to ensure connection strength and structural stability. The locking plate 22 is provided with an unlocking drive mechanism for unlocking. The unlocking drive mechanism can be a traction hole 221 at the rear end of the locking plate 22 or a pressing plate 222 at the front end of the locking plate 22, which are used for traction unlocking and pressing unlocking respectively. A latch magnet groove 223 is opened in the middle of the locking plate 22, and a latch magnet 2230 is embedded in the latch magnet groove 223 to form an attraction with the base magnet 1210 in the magnetic base 1. The locking plate 22 has a locking hole 224 at the front, and a locking tongue 2241 protrudes from the rear side of the locking hole 224. A latching guide surface 22411 is provided on the lower side of the locking tongue 2241. A guide rib 2242 is provided below the front side of the locking hole 224. Assembly guide surfaces 225 are provided on both sides of the rear end of the locking plate 22. A locking limiting groove 226 corresponding to the locking limiting rib 2111 on the buckle seat 21 is provided at the front of the assembly guide surface 225 to limit the locking plate 22 to slide smoothly along a set trajectory.

[0019] Work process: When assembling the magnetic hook and loop fastener 2, align the assembly guide surface 225 at the rear end of the locking plate 22 with the front ends of the locking cavity 211 on both sides, and insert it into the locking cavity 211 under the guidance of the assembly guide surface 225 until the locking limit rib 2111 is engaged in the locking limit slide groove 226.

[0020] When fastening, the magnetic base 1 and the magnetic hook 2 are brought close together and automatically attracted and aligned under the action of magnetic force. The buckle 212 and the fastening boss 12 are fastened together, and the front end of the magnetic hook 2 is inserted into the fastening groove 15. The fastening reinforcement plate 215 at the front end of the buckle 212 and the fastening reinforcement surface 1224 on the rear side of the locking seat 122 abut against each other to ensure the strength of the fastening structure. During the fastening process, the fastening guide surface 22411 on the lower side of the latch 2241 and the guide rib 2242 on the lower front side of the locking hole 224 correspond to the locking guide surface 1223 on the front side of the locking seat 122 and the opening and closing rib 1222 on the rear side of the locking seat 122 to form a guiding fit, guiding the latch 2241 to be inserted into the locking hole 1221. In particular, during the fastening process, under the mutual attraction of the base magnet 1210 and the latch magnet 2230, before the two magnets are attracted, the fastening guide surface 22411 drives the latch 2241 to move longitudinally along the locking guide surface 1223 to below the locking guide surface 1223, and then guides the latch 2241 to move laterally until the latch 2241 is inserted into the locking hole 1221. At the same time, the two magnets are fully attracted, completing the locking.

[0021] During unlocking, pressing the pressing plate 222 or pulling the traction hole 221 causes the locking plate 22 to slide laterally backward within the locking cavity 211. The locking tongue 2241 retracts from the locking engagement hole 1221. The guide rib 2242 on the lower front side of the locking hole 224 slides obliquely upward along the opening and closing slope 1222 on the rear side of the locking seat 122, driving the front end of the locking plate 22 to move upward. This overcomes the mutual attraction between the base magnet 1210 and the latch magnet 2230, causing the locking plate 22 to separate from the latching boss 12. Simultaneously, it causes the latch ring 212 at the lower part of the latch seat 21 to leave the latching boss 12, thereby releasing the lock and separating the magnetic latch 2 from the magnetic base 1. During the unlocking process, the lateral sliding range of the locking plate 22 within the locking cavity 211 is limited by the sliding range of the locking limiting rib 2111 within the locking limiting groove 226.

[0022] The beneficial effects of this invention are as follows: 1. The magnetic attraction formed by the base magnet 1210 and the snap magnet 2230 allows for quick alignment and automatic engagement without the need for precise alignment, enabling one-handed engagement. 2. The magnetic lock formed by the base magnet 1210 and the latch magnet 2230, combined with the mechanical lock formed by the locking seat 122 and the locking tongue 2241, provides a double lock with high connection strength and is not easy to accidentally loosen; 3. The fastening reinforcement surface 1224 and the fastening reinforcement plate 215 are set to enhance the fastening strength. Both the magnetic base 1 and the magnetic fastener 2 are equipped with reinforcing ribs (14, 214), which enhances the durability. 4. Flexible unlocking methods, supporting unlocking by pressing the press plate 222 and unlocking by pulling the traction hole 221, making it applicable to a wider range of scenarios; 5. The guide structure is well-designed. The opening and closing inclined surface 1222, the locking guide surface 1223, the fastening guide surface 22411, and the guide rib 2242 work together to make fastening and unlocking smoother.
