Description

Technical Field

[0001] The present invention relates to the technical field of connection fasteners, and particularly to magnetic buckles.

Background Art

[0002] Some members such as backpacks, baby carriers, child safety belts, and child seats usually need to achieve connection or maintain a specific state through buckles, and it is also necessary to be able to quickly and easily remove the buckles. For example, baby carriers or child safety belts usually need to be connected and disconnected during use, and this can be achieved by using buckles. Commonly seen buckles usually include male buckles and female buckles, and the male buckle and the female buckle are magnetically adsorbed and locked to achieve connection.

[0003] In conventional magnetic buckles, magnets are respectively provided on the male buckle and the female buckle, and they are adsorbed by the mutual magnetic attraction force of the two magnets. However, the adsorption force of the two magnets may be insufficient, and they may come off during use. During the locking and use process, the male buckle and the female buckle may shake or shift, resulting in unstable locking, and the product quality is relatively common.

[0015] Compared to conventional technology, the beneficial effects that this invention can achieve are as follows:

[0016] The female buckle of this invention includes a base, a cover, a magnetic adsorption member mounted in the cavity of the base, a locking member, and a push button. The locking member is linked to the push button, and pressing the push button drives the locking member to move in order to release the lock relationship with the male buckle. The push button and the locking member move and return to their original positions due to their own repulsive force. In this design, the locking member connects the two locking parts using a spring plate, and utilizes the physical structure of the spring plate to movably unlock or lock. When the male and female buckles are assembled, there is no need to press the push buttons on both sides, and the movable unlock of the locking member can be pushed by magnetic adsorption and guidance alone. The locked locking member returns to its original position due to its own repulsive force, making it easy to operate and easy for the user to use.

[0017] The mounting cavity is covered by the outer contour of the locking member, and the locking member always moves along the inner contour of the mounting cavity, allowing it to move only horizontally along a set pressing trajectory. If it attempts to swing vertically, it is restrained by the mounting cavity, significantly improving the stability of movement, making it less prone to shaking, and ensuring superior product quality.

[0018] The attachment of the male and female buckles is relatively stable, and by assembling the mounting cavity of the female buckle and the central hole of the male buckle as the first lateral position limit, and assembling the second convex ring of the male buckle and the first convex ring of the female buckle as the second lateral position limit, the stability of the locked female and male buckles is greatly improved, making them less prone to shaking.

Mode for Carrying Out the Invention

[0020] Hereinafter, referring to the drawings in the embodiments of the present invention, the technical means in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present invention.

[0021] As shown in FIGS. 1 to 9, the magnetic buckle includes a female buckle 1 and a male buckle 2 that are attracted and locked to each other. The male buckle 2 is attached to a backpack, a baby carrier, a child seat, etc., and is locked and fixed vertically with the female buckle 1 by a magnetic adsorption method. The female buckle 1 includes a base 3 and a cover 4 connected to the base 3. A cavity 7 for attaching and locking the male buckle is provided in the base 3. The cover 4 covers the cavity 7. A push button 5, a locking member 8, and a magnetic adsorption member 6 are provided in the cavity 7 of the base. The push button 5 is interlocked with the locking member 8, and the locking member 8 is pressed and moved by the push button 5 to release the locking relationship with the male buckle 2. The locking member 8 partially penetrates the cavity 7 and locks with the male buckle 2 on the back of the base 3. The push button 5 includes a protruding pin 13 that is interlocked with the locking member 8, and the locking member 8 is provided with a contact surface that engages with the protruding pin. When the female buckle 1 and male buckle 2 are locked, the protruding pin 13 moves away from the contact surface, and when the female buckle 1 and male buckle 2 are unlocked, the protruding pin 13 moves close to the contact surface. The push button 5 is provided with a push block 14 that pushes the male buckle 2 away from the female buckle 1. The push block 14 moves together with the push button 5 and contacts the top surface 15 of the male buckle, pushing the male buckle 2 away from the female buckle 1. While the push button 5 is stationary, the male buckle 2 approaches the female buckle 1, and the female buckle 1 is guided by the magnetic adsorption member 6 to lock the male buckle 2 and the locking member 8. The push button 5 is moved inward by the force it receives, and the locking member 8, which is linked to the push button, contracts inward as its ejector pin contacts the contact surface, moving away from the male buckle. During the movement of the push button, the push block moves with the push button, contacts the male buckle, and changes the positions of the male buckle and the female buckle.

[0022] An enclosing groove 16 is provided on the outside of the locking member 8, surrounding the inner end of the ejector pin 13. The inner end of the ejector pin 13 moves together with the push button 5, moving away from the inner wall of the enclosing groove 16 or coming into contact with the inner wall of the enclosing groove 16.

[0023] The contact surface on the locking member 8 includes a first contact surface 17 located on the inner wall of the surrounding groove 16, and the ejector pin 13 is provided with a second contact surface 18 and a third contact surface 19 distributed along the direction of movement of the push button. In the locked state, the second contact surface 18 and the third contact surface 19 are separated from the first contact surface 17, and in the unlocked state, the second contact surface 18 and the third contact surface 19 are close to the first contact surface 17.

[0024] A sliding groove 20 is provided along the front-rear direction on the inner wall of the enclosed groove 16, and a position limiting column 21 is provided on the inner surface of the cover 4, and the position limiting column 21 fits into the sliding groove 20 when the cover 4 and the base 3 are attached.

[0025] The locking member 8 includes two symmetrical locking parts 22 and a spring plate 23 connecting them. Specifically, the two locking parts 22 are connected using two vertically parallel V-shaped spring plates. The surrounding groove 16 is provided on the outside of the locking parts 22. The ejector pin 13 of the push button 5 moves to drive the two locking parts 22 by the spring plate to move closer to or away from the center, thereby unlocking or locking with the male buckle 2. A space for movement is formed between the two locking parts 22. A mounting cavity 32 is provided within the cavity 7, protruding toward the back of the base 3. The magnetic adsorption member 6 is provided at the bottom of the mounting cavity 32, and the movement of the two locking parts 22 is restricted by the inner wall of the mounting cavity 32. The mounting cavity 32 covers the outer circumference of the locking member 8, and the locking member 8 always moves within the mounting cavity 32 and is restrained by the mounting cavity 32, so that it can move only along the set pressing trajectory, which greatly improves the stability of the movement of the locking member 8, making it less prone to shaking and ensuring product quality.

[0026] The width and thickness of the spring plate 23 are smaller than those of the locking portion 22, allowing movement between the two locking portions 22 with only a small external force. The locking portions 22 and the spring plate 23 are integrally molded and do not require assembly, making the use and installation of the entire magnetic buckle easier. A space for movement is formed between the two locking portions 22, and when the push button 5 is pressed, the ejector pin 13 of the push button 5 pushes the two locking portions 22 together, gradually drawing them closer. After releasing the hand, the spring plate 23's repulsive force returns the two locking portions 22 to their original position, causing them to tightly adhere again to both ends of the inner wall of the mounting cavity 32.

[0027] First through-holes 39 are provided on both sides of the mounting cavity 32. The latch bolts 38 located outside the two locking parts 22 pass through the first through-holes on each side, then engage with the male buckle 2 to lock, pressing against the two locking parts 22 and driving the latch bolts 38 to move inward and enter the mounting cavity 32, thereby releasing the lock. Two first through-holes 39 corresponding to the two latch bolts 38 are provided on the left and right sides, respectively. If they are provided symmetrically, stability is enhanced.

[0028] A first convex ring 28 is provided on the back of the base 3, the male buckle 2 is annular, and a second convex ring 29 is provided on the side adjacent to the female buckle, an annular barb 30 that engages with the locking member 8 is provided on the inside of the second convex ring 29, the top surface 15 of the male buckle on the outside of the second convex ring 29 is in movable contact with the push block 14, the mounting cavity 32 passes through the central hole 37 of the second convex ring, a step 34 is provided on the inner wall of the central hole away from the female buckle, the chassis to which the suction member 36 is attached is fitted into the annular structure and contacts the step 34, and when the female buckle 1 and the male buckle 2 are assembled, the second convex ring 29 is fitted into the first convex ring 28. The latch bolt 38 of the locking member inside the female buckle 1 can hook onto the annular barb 30 of the male buckle at any position to achieve locking, thus solving the problem of being able to lock only at a specific angle and not at a different angle. Furthermore, the design of the convex ring allows the female buckle 1 and male buckle 2 to be quickly assembled at any angle.

[0029] An inclined guide portion 9 is provided on the outside of the latch bolt 38. The guide portion 9 is an inclined slope, and during the locking process between the male buckle 2 and the female buckle 1, the male buckle 2 can more easily push open the latch bolt 38 along the guide portion 9, thereby enabling assembly with the female buckle 1 and making assembly easier for the user.

[0030] The suction member 36 includes a metal member, a magnet, etc., and when the male buckle 2 and the female buckle 1 are locked together, the magnetic suction member 6 and the suction member 36 are attracted to each other.

[0031] Push button cavities 12 are symmetrically provided on both sides of the base 3, and the push buttons 5 are provided in the push button cavities 12, with their outer ends exposed to the outside of the push button cavities 12 and pressed by the user, and the upper and lower ends of the two push buttons 5 are connected by an elastic member 33, the ejector pins 13 and push blocks 14 are located inside the push buttons 5 and distributed along the front-to-back direction, the locking member 8 is provided in the area enclosed by the elastic member 33 and the push buttons 5, and a second through hole 41 is provided in the push button cavity 12 for the push block 14 to pass through and contact the top surface 15 of the male buckle. The elastic member 33 uses an arc-shaped structure that is arched outward, the elastic member 33 is integrally molded with the two push buttons 5 and returns to its original position due to the repulsive force of the elastic member 33 after the two push buttons 5 are pressed.

[0032] Positioning grooves 40 are provided on the upper and lower sides of the push button cavity 12 to limit the sliding stroke, and stoppers 31 are provided on both the upper and lower sides of the push button 5. When the push button 5 is pressed, the stoppers 31 slide within the positioning grooves 40. When moving, the two push buttons 5 can only move within the push button cavity 12, and when pressed inward to a certain extent, the stoppers 31 move inward to the inner end of the positioning grooves 40, limiting the maximum inward pressing distance of the two push buttons 5 and preventing damage due to overpressure. If either side of the push button 5 is accidentally touched and pressed, only the latch bolt 38 on one side will move, and the lock between the male buckle 2 and the female buckle 1 cannot be completely released. The lock can only be released by pressing both push buttons 5 simultaneously, preventing accidental detachment during daily use by the user, ensuring product stability, and providing the user with a good user experience.

[0033] Multiple position-restricting blocks 24 are provided within the cavity 7, and the locking member 8 moves either closer to the inside of some of the position-restricting blocks or away from the inside of some of the position-restricting blocks, forming a position-restricting groove 25 between two adjacent position-restricting blocks distributed along the vertical direction, and the ejector pin 13 moves left and right along the position-restricting groove 25. Pressing the push button 5 drives the ejector pin 13 to move toward the center along the position-restricting groove 25, causing the elastic member 33 to deform and drive the two locking parts 22 on the locking member to move toward the center, the first contact surface gradually coming into contact with the second and third contact surfaces, the latch bolt on the male buckle disengaging from the annular barb, and releasing the locked state between the female buckle and the male buckle.

[0034] One end of the base 3 is provided with a mounting position 26 for passing webbing through, and a cover plate 27 is provided at the mounting position 26. The cover plate is rotatably connected to the base 3 by a pivoting method, and after passing the webbing through, the cover plate 27 can be rotated to close and clamp the webbing, preventing the webbing from loosening.

[0035] This magnetic buckle is used in the following manner:

[0036] 1) The attachment of female buckle 1 and male buckle 2 is as follows: The first convex ring 28 on the back of the female buckle 1 and the second convex ring 29 on the front of the male buckle 2 are brought close to each other, and due to the mutual attractive force between the magnetic adsorption member 6 and the adsorption member 36, they come into close contact, causing the second convex ring 29 to fit onto the first convex ring 28. The inside of the second convex ring 29 is pushed inward, pushing open the latch bolt 38 on the back of the female buckle. The latch bolt 38 is pressed and pulled into the mounting cavity 32, and then protrudes and returns from the mounting cavity 32 until it contacts the annular barb 30 on the second convex ring 29, and is locked onto the annular barb 30.

[0037] 2) The process for unlocking the female buckle 1 and the male buckle 2 is as follows: When the left and right push buttons 5 on the female buckle 1 are pressed, the ejector pins 13 and push blocks 14 on the push buttons 5 push the locking portion 22 of the locking member 8 and the top surface 15 of the male buckle toward the center, and the second contact surface 18 and third contact surface 19 of the upper ejector pin 13 are gradually pushed toward the first contact surface 17, pushing the two locking portions 22 toward the center, driving the latch bolt 38 to be pulled into the mounting cavity 32, thereby unlocking the latch bolt 38 of the female buckle 1 and the annular barb 30 of the male buckle 2. At the same time, the lower push block 14 passes through the second through hole 41 of the mounting cavity 32 and contacts the top surface 15 of the male buckle on the back of the base, pushing the male buckle 2 toward the female buckle 1, completing the separation and unlocking of the female buckle 1 and the male buckle 2.
