Description

Technical Field

[0001] This utility model relates to the field of infant and toddler products technology, and in particular to a sliding quick-release device. Background Technology

[0002] Baby carriers are childcare tools specifically designed for young infants. Their ergonomic design distributes the weight of the parent, offering a combination of front-hold and hip-seat configurations. Made of breathable material, they feature an adjustable support structure to meet the neck protection needs of even very young infants, making them suitable for everyday outings, housework, and other situations where hands-free activities are required.

[0003] Existing baby carrier technology, such as the technical solution disclosed in Chinese Patent CN217118002U, includes a baby hip seat, a protective panel detachably connected to the hip seat, and shoulder straps connected to the protective panel. The protective panel includes a central front protective panel and side protective panels on both sides of the central protective panel. The central protective panel and either side protective panel have an opening and closing structure, suitable for placing the baby on the baby hip seat through this connection point. An adjustable anti-slip strip is connected between the shoulder straps to prevent them from slipping off the shoulders. The opening and closing structure is a zipper, which is easy for caregivers to open and close with one hand, making operation convenient.

[0004] Existing baby carriers typically consist of two parts: the carrier strap and the hip seat. These two parts are connected by a zipper. However, zippers require aligning both sides to close or open, which takes a long time. Furthermore, when the hip seat is used alone, the toothed structure of the zipper can easily chafe a baby's delicate skin, or even cause the zipper to get stuck on the skin, posing a danger. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a sliding quick-release device for baby carriers that allows for easy unlocking and fastening with a simple pull, ensuring a quick and secure connection without the risk of jamming. To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sliding quick-release device for connecting the carrying strap and waist belt of a baby carrier, the quick-release device comprising: An external buckle, fixed to the lower part of the shoulder strap, is equipped with a first magnetic element; The inner seat is fixed to the upper part of the belt and is provided with a second magnetic element. When the inner seat is fastened with the outer buckle, the first magnetic element and the second magnetic element attract each other. The unlocking component is movably disposed within the enclosed space of the inner seat and the outer buckle. The outer end of the unlocking component extends out of the enclosed space of the inner seat and the outer buckle. Pulling the outer end of the unlocking component forms a pressing force on the outer buckle, causing the outer buckle to slide relative to the inner seat and separating the outer buckle from the inner seat.

[0006] Based on the above technical solution, the present invention may also adopt the following further technical solutions: The outer buckle has a top pressing platform on its back, and a first fixing groove is formed on the top pressing platform. The first magnetic component is fixed in the first fixing groove. The inner seat has a second fixing groove on its back, and the second magnetic component is fixed in the second fixing groove. The upper end face of the top pressing platform has a locking block. The front part of the inner seat has a positioning cavity, and the upper surface of the positioning cavity has a locking groove.

[0007] The lower end face of the top pressing platform is an inclined first guide slope, and a first pressing cavity is formed on the first guide slope. The lower surface of the positioning cavity is an inclined second guide slope, and the lower part of the inner seat is provided with a second pressing cavity that extends from the lower surface of the inner seat to the upper surface of the second guide slope.

[0008] The lower part of the unlocking component is provided with a lifting part, which is exposed outside the enclosed space of the outer buckle and the inner seat. The upper part of the unlocking component is provided with a locking part, which passes through the second pressing cavity and is surrounded by the first pressing cavity. The end of the locking part is provided with an inclined third guide slope. When the outer buckle and the inner seat are fastened together, the third guide slope of the locking part presses against the first pressing cavity, and the locking block of the outer buckle is engaged in the locking groove of the inner seat.

[0009] The unlocking component also has a reset through hole, the upper part of which is engaged with an elastic element. The elastic element has an arc-shaped structure, and the lower part of the elastic element is fixed to the lower opening of the second pressure cavity of the inner seat.

[0010] The unlocking component has a deformation cavity, and a limiting rod that passes through the deformation cavity is provided on the side wall of the deformation cavity.

[0011] The side of the top pressing platform is provided with a first top pressing cavity, and the side of the inner seat is provided with a second top pressing cavity. One end of the unlocking member is provided with a locking part, and the other end of the unlocking member is provided with a lifting part. The lifting part is exposed outside the enclosed space of the outer buckle and the inner seat. The locking part passes through the second top pressing cavity and is surrounded by the first top pressing cavity. The end of the locking part is provided with an inclined third guide slope. When the outer buckle and the inner seat are fastened together, the third guide slope of the locking part presses against the first top pressing cavity, and the buckle's locking block is engaged in the inner seat's locking groove.

[0012] The inner seat also has a reset cavity, which has a circular protrusion and a reset component. The reset component has a positioning hole and is movably sleeved on the protrusion at the positioning hole.

[0013] The upper end of the reset component is provided with a pressing part, the reset cavity is provided with a pressing hole that penetrates the positioning cavity, the pressing part of the reset component extends out from the pressing hole and the end of the pressing part is exposed in the positioning cavity, and the end of the pressing part is provided with an inclined fourth guide slope.

[0014] The lower end of the reset component is provided with a limiting block, and the unlocking component is provided with a limiting groove. The limiting block of the reset component is limited to the limiting groove of the unlocking component. When the unlocking component is stretched outward, the limiting block is driven by the limiting groove to offset, so that the reset component rotates around the protrusion as an axis and the top pressing part of the reset component presses against the outer pressing platform.

[0015] Compared with the prior art, the beneficial effects that this utility model can achieve are: This invention utilizes a magnetic component to quickly and easily achieve the magnetic locking of the outer buckle and inner seat. When separation is required, simply pulling the unlocking component outward generates a displacement force on the outer buckle, causing it to slide relative to the inner seat, thus unlocking it quickly and easily. This quick-release device completely revolutionizes the traditional zipper connection method, effectively solving the problems associated with zippers and offering convenient operation and rapid assembly / disassembly.

Detailed Implementation

[0038] Combined with appendix Figure 1-21 This invention provides a further description of a sliding quick-release device. The invention includes three specific embodiments, with the specific solution of Embodiment 1 corresponding to the attached diagram. Figure 1-8 The structure shown corresponds to the specific scheme of Embodiment 2. Figure 9-15 The structure shown corresponds to the specific scheme in Embodiment 3. Figure 16-21 The structure shown.

[0039] Example 1: A sliding quick-release device for connecting the baby carrier strap 11 and waist belt 12, including an outer buckle 2, an inner seat 3 and an unlocking component 4.

[0040] Specifically, the outer buckle 2 is fixed to the lower part of the shoulder strap 11, and a first magnetic element 51 is provided inside it.

[0041] Furthermore, the inner seat 3 is fixed to the upper part of the waist belt 12, and a second magnetic element 52 is provided inside it. When the inner seat 3 is fastened with the outer buckle 2, the first magnetic element 51 and the second magnetic element 52 attract each other.

[0042] Furthermore, the unlocking component 4 is movably disposed within the enclosed space of the inner seat 3 and the outer buckle 2. The outer end of the unlocking component 4 extends out of the enclosed space of the inner seat 3 and the outer buckle 2. Pulling the outer end of the unlocking component 4 forms a pressing force on the outer buckle 2, thereby causing the outer buckle 2 to slide relative to the inner seat 3 and separating the outer buckle 2 from the inner seat 3.

[0043] Furthermore, the back of the outer buckle 2 is provided with a top pressing platform 21, on which a first fixing groove 22 is opened, and the first magnetic component 51 is fixed in the first fixing groove 22. The upper end face of the top pressing platform 21 is provided with a locking block 23, and the lower end face of the top pressing platform 21 is an inclined first guide slope 24, on which a first pressing cavity 25 is opened.

[0044] Furthermore, a second fixing groove 31 is provided on the back of the inner seat 3, and the second magnetic element 52 is fixed in the second fixing groove 31. A positioning cavity 32 is provided at the front of the inner seat 3. A slot 33 is provided on the upper surface of the positioning cavity 32. The lower surface of the positioning cavity 32 is an inclined second guide slope 34. A second pressing cavity 35 is provided at the lower part of the inner seat 3, extending from the lower surface of the inner seat 3 to the upper surface of the second guide slope 34.

[0045] Furthermore, the lower part of the unlocking component 4 is provided with a lifting part 41, which is exposed outside the enclosed space of the outer buckle 2 and the inner seat 3. The upper part of the unlocking component 4 is provided with a locking part 42, which passes through the second pressing cavity 35 and is surrounded by the first pressing cavity 25. The end of the locking part 42 is provided with an inclined third guide slope 43. When the outer buckle 2 and the inner seat 3 are fastened together, the third guide slope 43 of the locking part 42 presses against the first pressing cavity 25, and at the same time, the locking block 23 of the outer buckle 2 is engaged in the locking groove 33 of the inner seat 3.

[0046] Furthermore, the unlocking component 4 also has a reset through hole 44, the upper part of which is engaged with an elastic component 6, which has an arc-shaped structure, and the lower part of which is fixed to the lower opening of the second pressure cavity 35 of the inner seat 2.

[0047] Specifically, in this embodiment, the quick-release device is fixed to the baby waist stool, and the specific connection position of the quick-release device is as follows: the upper part of the outer buckle 2 is fixed to the lower part of the carrier 11, and the lower part of the inner seat 3 is fixed to the upper part of the waist stool 12.

[0048] The quick-release device is fastened as follows: Simply bring the outer buckle 2 close to the inner seat 3 and align the top pressure plate 21 of the outer buckle 2 with the positioning cavity 32 of the inner seat 3. This will fasten the outer buckle 2 to the inner seat 3. At this time, the first magnetic component 51 and the second magnetic component 52 attract each other, causing the outer buckle 2 and the inner seat 3 to be tightly fastened, thus ensuring a close connection between the shoulder strap 11 and the waist stool 12. Simultaneously, combined with the design of the locking block 23 and the locking slot 33, a locking mechanism can be added to the magnetic fixation, achieving multiple fixations between the outer buckle 2 and the inner seat 3, thereby increasing the firmness of the fixation between the shoulder strap 11 and the waist stool 12.

[0049] The quick-release device is separated as follows: pinch the lifting part 41 of the unlocking part 4 and pull the unlocking part 4 downward. As the unlocking part 4 pulls down, it generates an outward pressure on the outer buckle 2, causing the outer buckle 2 to slide obliquely relative to the inner seat 3, thereby reducing the attraction force between the first magnetic part 51 and the second magnetic part 52. Combined with the interaction of the first guide slope 24 and the second guide slope 34, the outer buckle 2 and the inner seat 3 are separated. At this time, the outer buckle 2 and the inner seat 3 can be separated by simply applying external force with the other hand, further separating the shoulder strap 11 and the waist stool 12.

[0050] Example 2: A sliding quick-release device for connecting the baby carrier strap 11 and waist belt 12, including an outer buckle 2, an inner seat 3 and an unlocking component 4.

[0051] Specifically, the outer buckle 2 is fixed to the lower part of the shoulder strap 11, and a first magnetic element 51 is provided inside it.

[0052] Furthermore, the inner seat 3 is fixed to the upper part of the waist belt 12, and a second magnetic element 52 is provided inside it. When the inner seat 3 is fastened with the outer buckle 2, the first magnetic element 51 and the second magnetic element 52 attract each other.

[0053] Furthermore, the unlocking component 4 is movably disposed within the enclosed space of the inner seat 3 and the outer buckle 2. The outer end of the unlocking component 4 extends out of the enclosed space of the inner seat 3 and the outer buckle 2. Pulling the outer end of the unlocking component 4 forms a pressing force on the outer buckle 2, thereby causing the outer buckle 2 to slide relative to the inner seat 3 and separating the outer buckle 2 from the inner seat 3.

[0054] Furthermore, the back of the outer buckle 2 is provided with a top pressing platform 21, on which a first fixing groove 22 is opened, and the first magnetic component 51 is fixed in the first fixing groove 22. The upper end face of the top pressing platform 21 is provided with a locking block 23, and the lower end face of the top pressing platform 21 is an inclined first guide slope 24, on which a first pressing cavity 25 is opened.

[0055] Furthermore, a second fixing groove 31 is provided on the back of the inner seat 3, and the second magnetic element 52 is fixed in the second fixing groove 31. A positioning cavity 32 is provided at the front of the inner seat 3. A slot 33 is provided on the upper surface of the positioning cavity 32. The lower surface of the positioning cavity 32 is an inclined second guide slope 34. A second pressing cavity 35 is provided at the lower part of the inner seat 3, extending from the lower surface of the inner seat 3 to the upper surface of the second guide slope 34.

[0056] Furthermore, the lower part of the unlocking component 4 is provided with a lifting part 41, which is exposed outside the enclosed space of the outer buckle 2 and the inner seat 3. The upper part of the unlocking component 4 is provided with a locking part 42, which passes through the second pressing cavity 35 and is surrounded by the first pressing cavity 25. The end of the locking part 42 is provided with an inclined third guide slope 43. When the outer buckle 2 and the inner seat 3 are fastened together, the third guide slope 43 of the locking part 42 presses against the first pressing cavity 25, and at the same time, the locking block 23 of the outer buckle 2 is engaged in the locking groove 33 of the inner seat 3.

[0057] Furthermore, the unlocking component 4 has a deformation cavity 45, and a limiting rod 46 is provided on the side wall of the deformation cavity 45, which passes through the deformation cavity 45.

[0058] Furthermore, there are two unlocking components 4 and two pressing platforms 21. The two pressing platforms 21 are respectively located on both sides of the outer buckle 2, and the two pressing platforms 21 have a mirror symmetrical structure.

[0059] Specifically, in this embodiment, the quick-release device is fixed to the baby waist stool, and the specific connection position of the quick-release device is as follows: the upper part of the outer buckle 2 is fixed to the lower part of the carrier 11, and the lower part of the inner seat 3 is fixed to the upper part of the waist stool 12.

[0060] The quick-release device is fastened as follows: The outer buckle 2 is brought close to the inner seat 3, and the two pressure plates 21 of the outer buckle 2 are aligned with the two positioning cavities 32 of the inner seat 3, thus fastening the outer buckle 2 to the inner seat 3. At this time, the two sets of first magnetic elements 51 and second magnetic elements 52 on both sides of the outer buckle 2 and the inner seat 3 attract each other, making the outer buckle 2 and the inner seat 3 tightly fastened, so that the shoulder strap 11 and the waist stool 12 are tightly joined together. Simultaneously, combined with the design of the locking block 23 and the locking slot 33, a locking fixation can be added on top of the magnetic fixation, achieving multiple fixations for the outer buckle 2 and the inner seat 3, thereby increasing the firmness of the fixation between the shoulder strap 11 and the waist stool 12.

[0061] The quick-release device is separated as follows: Pinch the lifting parts 41 of the two unlocking parts 4 on both sides and pull the unlocking parts 4 downwards. The downward pull of the unlocking parts 4 generates an outward pressure on the outer buckle 2, causing the outer buckle 2 to slide obliquely relative to the inner seat 3. This reduces the attraction force between the two sets of first magnetic parts 51 and second magnetic parts 52. Combined with the action of the two first guide slopes 24 and their corresponding two second guide slopes 34, the outer buckle 2 and the inner seat 3 are separated. At this point, the outer buckle 2 and the inner seat 3 can be separated simply by applying external force, further separating the shoulder strap 11 and the waist stool 12. In this embodiment, the unlocking part 4 is equipped with a return structure, meaning that after the external force applied to the unlocking part 4 is released, the unlocking part 4 can automatically reset through the deformation cavity and its structural design.

[0062] Example 3: A sliding quick-release device for connecting the baby carrier strap 11 and waist belt 12, including an outer buckle 2, an inner seat 3 and an unlocking component 4.

[0063] Specifically, the outer buckle 2 is fixed to the lower part of the shoulder strap 11, and a first magnetic element 51 is provided inside it.

[0064] Furthermore, the inner seat 3 is fixed to the upper part of the waist belt 12, and a second magnetic element 52 is provided inside it. When the inner seat 3 is fastened with the outer buckle 2, the first magnetic element 51 and the second magnetic element 52 attract each other.

[0065] Furthermore, the unlocking component 4 is movably disposed within the enclosed space of the inner seat 3 and the outer buckle 2. The outer end of the unlocking component 4 extends out of the enclosed space of the inner seat 3 and the outer buckle 2. Pulling the outer end of the unlocking component 4 forms a pressing force on the outer buckle 2, thereby causing the outer buckle 2 to slide relative to the inner seat 3 and separating the outer buckle 2 from the inner seat 3.

[0066] Furthermore, the back of the outer buckle 2 is provided with a pressing platform 21, on which a first fixing groove 22 is formed, and a first magnetic element 51 is fixed in the first fixing groove 22. The back of the inner seat 3 is provided with a second fixing groove 31, and a second magnetic element 52 is fixed in the second fixing groove 31. The upper end face of the pressing platform 21 is provided with a locking block 23, and the front part of the inner seat 3 is provided with a positioning cavity 32, on which a locking groove 33 is formed on the upper surface.

[0067] Furthermore, the side of the top pressing platform 21 is provided with a first top pressing cavity 25, the side of the inner seat 3 is provided with a second top pressing cavity 35, one end of the unlocking member 4 is provided with a locking part 42, and the other end of the unlocking member 4 is provided with a lifting part 41, which is exposed outside the enclosed space of the outer buckle 2 and the inner seat 3.

[0068] Furthermore, the locking part 42 passes through the second pressing cavity 35 and is surrounded by the first pressing cavity 25. The end of the locking part 42 is provided with an inclined third guide slope 43. When the outer buckle 2 and the inner seat 3 are fastened together, the third guide slope 43 of the locking part 42 presses against the first pressing cavity 25, and at the same time, the locking block 23 of the outer buckle 2 is engaged in the locking groove 33 of the inner seat 3.

[0069] Furthermore, the inner seat 3 is also provided with a reset cavity 36, which has a circular protrusion 37 and a reset member 7. The reset member 7 has a positioning hole 71 and is movably sleeved on the protrusion 37 at the positioning hole 71.

[0070] Furthermore, the upper end of the reset member 7 is provided with a pressing part 72, and the reset cavity 36 is provided with a pressing hole 38 that passes through the positioning cavity 32. The pressing part 72 of the reset member 7 extends out from the pressing hole 38, and the end of the pressing part 72 is exposed in the positioning cavity 32.

[0071] Furthermore, the end of the pressing part 72 is provided with an inclined fourth guide slope 73.

[0072] Furthermore, the lower end of the reset member 7 is provided with a limiting block 74, and the unlocking member 4 is provided with a limiting groove 47. The limiting block 74 of the reset member 7 is limited within the limiting groove 47 of the unlocking member 4. When the unlocking member 4 is stretched outward, the limiting block 74 is driven by the limiting groove 47 to shift, thereby causing the reset member 7 to rotate about the protrusion 37 as an axis. This further causes the top pressing part 72 of the reset member 7 to press against the top pressing platform 21 of the outer buckle 2, thereby generating a top pressure on the outer buckle 2. Combined with the design of each guide slope, the outer buckle 2 and the inner seat 3 can be separated from each other.

[0073] Furthermore, there are two unlocking components 4 and two pressing platforms 21. The two pressing platforms 21 are respectively located on both sides of the outer buckle 2, and the two pressing platforms 21 have a mirror symmetrical structure.

[0074] Specifically, in this embodiment, the quick-release device is fixed to the baby waist stool, and the specific connection position of the quick-release device is as follows: the upper part of the outer buckle 2 is fixed to the lower part of the carrier 11, and the lower part of the inner seat 3 is fixed to the upper part of the waist stool 12.

[0075] In particular, in this embodiment, a reset member 7 is provided in the inner seat 3, so that the unlocking member 4 can be automatically reset after the outer buckle 2 is separated from the inner seat 3, further reducing the time spent on disassembly and assembly.

[0076] The quick-release device engages by bringing the outer buckle 2 close to the inner seat 3 and aligning the two pressure plates 21 of the outer buckle 2 with the two positioning cavities 32 of the inner seat 3. This engages the outer buckle 2 with the inner seat 3. At this time, the two sets of first magnetic elements 51 and second magnetic elements 52 on both sides of the outer buckle 2 and the inner seat 3 attract each other, ensuring a tight fit between the outer buckle 2 and the inner seat 3, thus tightly connecting the shoulder strap 11 and the waist stool 12. Furthermore, the design incorporates locking blocks 23 and slots 33, adding locking mechanisms to the magnetic fixation, achieving multiple layers of fixation between the outer buckle 2 and the inner seat 3, thereby increasing the strength of the fixation between the shoulder strap 11 and the waist stool 12.

[0077] The quick-release device is separated as follows: Pinch the lifting part 41 of the two unlocking parts 4 on both sides and pull the unlocking parts 4 downward. As the unlocking parts 4 pull down, they generate an outward pressure on the outer buckle 2, causing the outer buckle 2 to slide obliquely relative to the inner seat 3. This reduces the attraction force between the two sets of first magnetic parts 51 and second magnetic parts 52. Combined with the action of the two first guide slopes 24 and the two corresponding second guide slopes 34, the outer buckle 2 and the inner seat 3 are separated. At this time, the outer buckle 2 and the inner seat 3 can be separated by simply applying external force, further separating the shoulder strap 11 and the waist stool 12.

[0078] The automatic reset process of the unlocking component 4 is as follows: After the external force applied to the unlocking component 4 is released, the unlocking component 4 can be stretched outward by the action of the reset component 7 pressing against it within the limiting groove 47. When the unlocking component 4 is stretched outward, the limiting block 74 is driven to shift by the limiting groove 47, thereby causing the reset component 7 to rotate about the protrusion 37 as an axis. When the external force disappears, the rotation of the reset component 7 causes the unlocking component 4 to return to its initial position, thus achieving the automatic reset of the unlocking component 4.

[0079] This utility model has been illustrated and described with reference to preferred embodiments; however, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
