Technical Field
[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a magnetic quick-release device. Background Technology
[0002] Newborn babies cannot walk independently and usually need to be carried by family members when going out. However, mothers' hands may find it difficult to hold their babies for extended periods. To free up mothers' hands, baby carriers have been invented. Baby carriers typically consist of a waist belt and a carrying strap worn by the mother, as well as a cloth sling for the baby to sit in. One end of the sling is connected to the carrying strap, and the other end usually has a buckle that connects to the waist belt. A seat can also be attached to the sling for the baby to sit on.
[0003] When a baby is placed in or removed from a baby carrier, the cloth bag needs to be frequently fastened and disassembled. Therefore, a detachable connection structure between the cloth bag and the waist belt is essential. Existing baby carriers use several snaps or buckles for fastening, which is cumbersome to lock and unlock, and the locking strength is generally weak, making it easy for the bag to come loose.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-5As shown, a magnetic quick-release device, typically used for installation on baby carriers, includes an upper connector 1 for mounting on a cloth bag and a lower connector 2 for mounting on a waist belt. The two ends of the lower connector 2 and the upper connector 1 can be fastened together. A fastening part 5 is provided between the upper connector 1 and the lower connector 2, and a pin 6 is also included for partially inserting into the fastening part 5. The upper connector 1 and the lower connector 2 are fastened together by the fastening part 5 and locked by the pin 6. The fastening part 5 includes two protruding locking blocks 7 at the lower end of the upper connector 1 and a locking groove 8 on the lower connector 2 that adapts to the locking blocks 7. A limiting part 25 is provided between the locking blocks 7 and the locking groove 8. When the upper connector 1 and the lower connector 2 are fastened together, the locking blocks 7 are embedded in the locking groove 8, and the limiting part 25 forms a limit to increase the stability after fastening. The upper connector 1 is equipped with a first magnet 9, the lower connector 2 is equipped with a second magnet 10, and the pin 6 is equipped with a third magnet 11. The upper connector 1 and the lower connector 2 are magnetically attracted to each other, which can enhance the connection strength after the connection is made and can also guide the connection process. There is no need to find the precise position, which makes it convenient for users to use in daily life.
[0025] The fastening part 5 includes a locked state and an unlocked state: In the locked state, the card block 7 is placed into the card slot 8 from top to bottom. The first magnet 9 and the second magnet 10 guide the card block 7 to push the pin 6 to move away from the card slot 8, so that the card block 7 can be fully fastened into the card slot 8. The limiting part 25 forms a limit, and the upper connecting member 1 and the lower connecting member 2 are fastened. Then, the second magnet 10 and the third magnet 11 guide the pin 6 to move and reset the locking of the card block 7 by magnetic attraction. The fastening part 5 is locked, and the upper connecting member 1 and the lower connecting member 2 are locked and cannot be separated. In the unlocked state, the pin 6 is moved, and the limit between the pin 6 and the card block 7 is released. At the same time, the pin 6 drives the upper connecting member 1 to move and release the limiting state of the limiting part 25. The lock of the fastening part 5 is released, and the upper connecting member 1 and the lower connecting member 2 are separated from each other. The upper connector 1 and the lower connector 2 can be unlocked simply by using the movable pin 6. When it is necessary to fasten, simply place the upper connector 1 on the lower connector 2, and it will be easily fastened and locked by magnetic attraction. It is convenient to use and easy to fasten and unlock.
[0026] The limiting part 25 includes a limiting groove 14 recessed in the upper side wall of the slot 8 and a limiting block 13 protruding in the side wall of the block 7. When the block 7 is fully embedded in the slot 8, the limiting block 13 is also embedded in the limiting groove 14, increasing the stability after fastening and making it less prone to shaking. The top surface of the pin 6 is provided with a protruding wedge-shaped block 19, and the bottom surface of the upper connector 1 is provided with a wedge-shaped groove 20 that matches the wedge-shaped block 19. The wedge-shaped block 19 and the wedge-shaped groove 20 have mutually matching inclined surfaces. The lateral movement of the pin 6 drives the wedge-shaped block 19 to move synchronously. The wedge-shaped block 19 moves laterally along the inclined surface of the wedge-shaped groove 20, causing the entire upper connector 1 to move downward, so that the limiting block 13 disengages from the limiting groove 14, thereby unlocking the limiting part 25.
[0027] The lower connector 2 is provided with a pin groove 12, and the pin 6 is installed in the pin groove 12 in a horizontally movable manner. A first locking part 3 and a second locking part 4 are provided between the pin 6 and the locking block 7. The first locking part 3 and the second locking part 4 are located on the left and right sides respectively. After the locking block 7 is engaged with the locking groove 8, the pin 6 is locked with the locking block 7 through the first locking part 3 and the second locking part 4, so that the locking block 7 cannot be disengaged from the locking groove 8.
[0028] The first locking part 3 includes a first groove 16 recessed in the side wall of the locking block 7 and a first locking block 15 at one end of the pin 6. The second locking part 4 includes a second groove 18 recessed in the side wall of the locking block 7 and a second locking block 17 at the other end of the pin 6. The first locking block 15 and the second locking block 17 extend out of the pin groove 12 and are longitudinally locked to the first groove 16 and the second groove 18 on the locking block 7, respectively. This design uses the limiting part 25, the first locking part 3, and the second locking part 4 for multiple limiting, which greatly increases the connection strength between the upper connecting part 1 and the lower connecting part 2, ensures good product quality, and prevents the upper connecting part 1 from separating from the lower connecting part 2 during use, thus preventing a poor user experience.
[0029] When unlocking is required, pulling the pin 6 causes it to move laterally to one side, causing the first locking block 15 and the second locking block 17 to disengage from the first groove 16 and the second groove 18 respectively, thus releasing the locks of the first locking part 3 and the second locking part 4. At the same time, when the pin 6 moves laterally, it moves along the inclined surface of the wedge groove 20 through the wedge block 19, thereby realizing the pin 6's linkage with the entire upper connecting part 1 to move longitudinally and release the limiting state of the limiting part 25.
[0030] The first locking block 15 and the second locking block 17 are provided with guide surfaces 26, which are inclined surfaces. When the upper connecting member 1 and the lower connecting member 2 are engaged, the locking block 7 moves downward along the guide surface 26, pushing the first locking block 15 and the second locking block 17, which are in the slot 8, open to facilitate the engagement of the locking block 7. The design of the guide surface 26 helps the locking block 7 to push the first locking block 15 and the second locking block 17 open more easily, and makes the engagement smoother.
[0031] Guide grooves 21 are provided on the side walls on both sides of the pin groove 12, and guide blocks 22 are provided on both sides of the pin 6. When the pin 6 moves laterally, the guide blocks 22 move in the guide grooves 21. The size of the guide grooves 21 is the maximum distance that the pin 6 can move. When the pin 6 is pulled out to the maximum distance, the guide blocks 22 abut against the end of the guide grooves 21 and cannot be pulled out further. This is used to control the movement distance of the pin 6 and also to prevent the entire pin 6 from being pulled out due to excessive force.
[0032] One end of the pin 6 is provided with a handle position 23, which allows the user to grasp the handle position 23 and slide the pin 6, facilitating the movement of the pin 6.
[0033] The lower connector 2 is provided with a hollow part 24, which is located between the two connecting blocks 3. The hollow design in the center of the lower connector 2 reduces material consumption and lowers production costs.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
