Description

Technical Field

[0001] This utility model relates to the field of down comforter core production technology, specifically a wearable down comforter core. Background Technology

[0002] In cold environments, down products are widely used due to their excellent warmth retention. Traditional down comforters are mainly used for sleeping as static warmth retention tools. Their design focuses on large-area coverage to achieve the warmth retention effect, but they have obvious limitations in dynamic scenarios that require human movement. Traditional down comforters lack a structure adapted to human movement. When users need to walk, work, or engage in other physical activities, the comforter tends to slip off and restrict the limbs, making it difficult to balance warmth and freedom of movement. Especially in the neck area, traditional down comforters often use a fixed collar design, which cannot be adjusted according to the neck circumference of different people. This can lead to discomfort due to being too tight or air leakage due to being too loose, resulting in reduced warmth efficiency in the core area. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wearable down comforter core, which solves the problems of traditional down comforters easily slipping off in dynamic scenarios, restricting movement, and having poor warmth fit in the neck and arm areas.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wearable down comforter core, comprising: a comforter body, wherein a movable ring is fixedly connected to the inner wall of the comforter body, the movable ring being located at the neck position of the human body; Velcro is symmetrically fixedly connected to the outer wall of the comforter body, the Velcro being located in the arm area of ​​the human body; a drawstring is slidably connected to the inner wall of the movable ring, and a limit tube is slidably connected to the outer wall of the drawstring; the comforter body has a movable ring at the neck position, which, together with the drawstring, allows for flexible adjustment of the neckline tightness. This not only reduces heat loss from the neck gap by tightening the movable ring, but also adapts to the neck circumference of different people, avoiding the problems of being too tight or too loose and leaking air caused by traditional fixed neckline designs.

[0005] Preferably, the inner wall of the limiting cylinder is slidably connected with a sliding rod.

[0006] Preferably, the inner wall of the slide bar is slidably connected to the outer wall of the pull rope.

[0007] Preferably, a compression spring is fixedly connected to the end face of the slide rod, and the end of the compression spring away from the slide rod is fixedly connected to the limiting cylinder. The limiting cylinder outside the pull rope, together with the slide rod and the compression spring, forms a stable adjustment mechanism. The elastic force of the compression spring can continuously limit the pull rope, preventing loosening caused by movement after pulling. The sliding connection between the slide rod and the limiting cylinder makes the pull operation smoother, reduces wear on the pull rope, and extends the product's service life.

[0008] Preferably, a cover cloth is attached to the end of the quilt body away from the limiting cylinder via Velcro. The cover cloth can be used to close the movable ring. The cover cloth is connected to the quilt body via Velcro, and the movable ring can be closed as needed. In extreme low temperature environments, it further enhances the neck sealing and warmth. When it is not necessary to close it, the convenient removal of Velcro will not affect the normal wearing of the product, thus improving the product's adaptability and flexibility in different temperature scenarios. Beneficial effects

[0009] This invention provides a wearable down comforter core. It has the following beneficial effects: This utility model, through the coordinated design of its components, features a movable ring and a pull-out cord that allow for flexible adjustment of the neckline tightness. Tightening the movable ring reduces heat loss through the neck gaps, while also adapting to different neck circumferences, avoiding the problems of excessive tightness or excessive looseness that can occur with traditional fixed neckline designs. The Velcro allows for adjustment of the fit to the arm area according to arm movement needs. When warmth is required, the Velcro is used to secure the garment, minimizing gaps during arm movement; when more freedom of movement is needed, the Velcro can be loosened to prevent restriction of the limbs. The elastic force of the compression spring provides continuous restraint to the pull-out cord, preventing loosening due to movement after pulling. The sliding connection between the slider and the limiting cylinder makes the pulling operation smoother, reducing wear on the pull-out cord and extending the product's lifespan.

[0012] 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. Example

[0013] Please see Figure 1-3 This utility model provides a technical solution: a wearable down comforter core, comprising: The quilt body 1 has a movable ring 2 fixedly connected to its inner wall, which is located at the neck position. The outer wall of the quilt body 1 is symmetrically fixedly connected with Velcro 8, which is located in the arm area. The quilt body 1 serves as the core carrier and is filled with down to provide basic warmth. The Velcro 8 symmetrically fixed to the outer wall of the quilt body 1 can flexibly adjust the fit to meet the movement needs of the arm area. When it is necessary to enhance warmth, the quilt body 1 is tightly fixed to the arm through the Velcro 8 to reduce the gap for movement. When flexible movement is required, the Velcro 8 can be torn off to release the restraint, achieving a seamless switch between static and dynamic scenes. A pull cord 3 is slidably connected to the inner wall of the movable ring 2. A limit cylinder 4 is slidably connected to the outer wall of the pull cord 3. A slide rod 5 is slidably connected to the inner wall of the limit cylinder 4. The inner wall of the slide rod 5 is slidably connected to the outer wall of the pull cord 3. A compression spring 6 is fixedly connected to the end face of the slide rod 5. The end of the compression spring 6 away from the slide rod 5 is fixedly connected to the limit cylinder 4. The movable ring 2, located at the neck position, can be adjusted for tension via the pull cord 3 slidably connected to its inner wall. The pull cord 3 can slide along the inner side of the movable ring 2. When the pull cord 3 is pulled outward, The movable ring 2 narrows in diameter due to the tightening of the rope, fitting snugly around the neck to reduce heat loss. When the pull rope 3 is released, the movable ring 2 returns to its natural state, avoiding excessive tightness. To ensure stable tightness after pulling, the limiting cylinder 4 sleeved on the outer wall of the pull rope 3 and the sliding rod 5 slidably connected to the inner wall form an adjustment mechanism. The sliding rod 5 generates elastic pressure through the compression spring 6 fixed at the end face, tightly pressing against the pull rope 3 to prevent it from loosening on its own during the activity. This ensures both ease of operation and improved structural durability. The end of the quilt body 1 away from the limiting cylinder 4 is attached to a cover cloth 7 via Velcro 8. The cover cloth 7 can be used to close the movable ring 2. The cover cloth 7 connected to the end of the quilt body 1 away from the limiting cylinder 4 via Velcro 8 can close the movable ring 2 as needed. In extreme low temperature environments, the cover cloth 7 is fixed by Velcro 8 to further seal the neck area and enhance the warmth retention effect. When it is not necessary to close it, the cover cloth 7 can be removed to restore the adjustment function of the movable ring 2, thereby improving the adaptability of the product in different temperature scenarios.

[0014] When in use, the quilt body 1 serves as the core carrier, and is filled with down to provide basic warmth; The movable ring 2 located at the neck position is adjusted for tightness via a pull cord 3 that slides along the inner wall. The pull cord 3 can slide along the inner side of the movable ring 2. When the pull cord 3 is pulled outward, the movable ring 2 shrinks in diameter due to the tightening of the cord, fitting snugly against the neck to reduce heat loss. When the pull cord 3 is released, the movable ring 2 returns to its natural state, avoiding excessive tightness. To ensure stable tightness after pulling, a limiting cylinder 4 fitted on the outer wall of the pull cord 3 and a sliding rod 5 that slides along the inner wall form an adjustment mechanism. The sliding rod 5 generates elastic pressure through a compression spring 6 fixed at its end face, tightly pressing against the pull cord 3 to prevent it from loosening during operation. This ensures both ease of operation and improved structural durability. To accommodate the movement needs of the arm area, the Velcro 8, which is symmetrically fixed to the outer wall of the body 1, can be flexibly adjusted to adjust the fit. When it is necessary to enhance warmth, the Velcro 8 can be used to tightly fix the body 1 to the arm, reducing gaps in movement. When flexible movement is required, the Velcro 8 can be torn off to release the restraint, achieving a seamless switch between static and dynamic scenarios.

[0015] In addition, the cover cloth 7, which is connected to the end of the body 1 away from the limiting cylinder 4 by Velcro 8, can close the movable ring 2 as needed. In extreme low temperature environments, the cover cloth 7 is fixed by Velcro 8 to further seal the neck area and enhance the warmth retention effect. When it is not necessary to close it, the adjustable function of the movable ring 2 can be restored by removing the cover cloth 7, which improves the adaptability of the product in different temperature scenarios.
