A detachable winter coat for boys Technical Field
[0001] This utility model specifically relates to a detachable winter coat for boys, belonging to the field of clothing technology. Background Technology
[0002] Detachable thermal tops are a type of thermal clothing that combines functionality and flexibility. Using zippers, snaps, and other connections, the outer windproof and waterproof fabric and the inner thermal lining are designed as a detachable and combinable structure. This design allows the wearer to freely disassemble or combine different parts according to temperature changes and usage scenarios. It provides all-around warmth in freezing weather and allows for easy disassembly and wearing when temperatures rise. Furthermore, each part can be independently disassembled and washed, extending the garment's lifespan. Combining practicality and convenience, it meets diverse warmth needs in different environments.
[0003] Currently, existing detachable winter jackets for boys on the market suffer from the following shortcomings: their warmth retention is insufficient, especially in extremely cold weather, failing to provide adequate insulation. Furthermore, their designs often overlook the active nature of boys, lacking sufficient freedom of movement and limiting comfort and flexibility when worn. Therefore, we propose a detachable winter jacket for boys. Summary of the Invention
[0004] To overcome the technical defects of existing technologies, this utility model provides a detachable boys' winter coat, comprising:
[0005] The garment body has a collar fixedly installed at the top, sleeves fixedly installed on both the left and right sides, two sleeves fixedly installed symmetrically on the front side of the garment body, an extended sleeve fixedly installed at one end of each sleeve, a thermal layer provided inside the extended sleeve, and pockets fixedly installed symmetrically on the front side of the garment body.
[0006] Two fixing rings are respectively fitted onto the two sleeves;
[0007] Two fixing rings are respectively fitted onto the two extended sleeves, and a sealing gasket is provided between the fixing ring and the fixing ring.
[0008] Two sets of fixing components are located on the two sleeves respectively and are used to fix the first fixing ring and the second fixing ring.
[0009] Through the coordination of the main body of the garment, collar, sleeves, extended sleeves, thermal layer, fixing ring one and fixing ring two, and fixing components, the overall device ensures sufficient warmth even in extremely cold weather conditions.

[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] As shown in the figure, this embodiment provides a detachable winter coat for boys, including:
[0027] The main body of the garment 1 has a collar 15 fixedly installed on the top of the main body of the garment 1, sleeves 3 fixedly installed on both the left and right sides of the main body of the garment 1, two sleeves 3 fixedly installed symmetrically on the front side of the main body of the garment 1, an extended sleeve 6 fixedly installed at one end of each of the two sleeves 3, a thermal insulation layer 7 is provided inside the extended sleeve 6, and pockets 2 are fixedly installed symmetrically on the front side of the main body of the garment 1.
[0028] Two fixing rings 4 are respectively fitted onto the two sleeves 3;
[0029] Two fixing rings 5 are respectively fitted onto two extended sleeves 6, and a sealing gasket 14 is provided between fixing ring 4 and fixing ring 5.
[0030] Two sets of fixing components are located on the two sleeves 3 respectively, and are used to fix the fixing ring 4 and the fixing ring 5.
[0031] The overall device, through the cooperation of the main body 1, collar 15, sleeves 3, extended sleeves 6, insulating layer 7, fixing ring 1 4 and fixing ring 2 5, and fixing components, ensures sufficient warmth even in extremely cold weather conditions. In terms of freedom of movement, it allows boys to move freely without restriction while wearing the garment, improving comfort and satisfying the active nature of boys.
[0032] In this embodiment, the fixing component includes:
[0033] Two fixing blocks 2 9 are fixedly installed on the left and right sides of fixing ring 1 4 respectively, and iron rings 10 are provided on the two fixing blocks 2 9;
[0034] Two fixing blocks 1 8 are fixedly installed on the left and right sides of the fixing ring 2 5 respectively. A cloth strip 12 is fixedly installed on the two fixing blocks 1 8. One side of the cloth strip 12 is provided with a hook and loop surface 11 and a hook and loop barbed surface 13, and the hook and loop surface 11 and the hook and loop barbed surface 13 are far apart from each other.
[0035] In this arrangement, the second fixing ring 5 can be aligned with the first fixing ring 4. Simultaneously, the sealing gasket 14 on the second fixing ring 5 will enter the first fixing ring 4, filling the gap between the first fixing ring 4 and the second fixing ring 5. This prevents cold air from entering the ring from the outside. Then, one end of the fabric tape 12 is pulled to pass through the iron ring 10. Next, the fabric tape 12 is pulled in the opposite direction, causing it to wrap around the iron ring 10 and tightly adhere the hook and loop fastener 13 to the hook and loop fastener 11, thus ensuring the hook and loop fastener... Under the combined action of the outer surface 13 and the hook and loop fastener 11, the metal ring 10 is pulled by the fabric strap 12, which fixes the first fixing ring 4 and the second fixing ring 5. At the same time, the extended sleeve 6 has strong heat insulation, ensuring that the hands will not get cold in cold weather. When the boy needs to play, the cuff is too long. Pull one end of the fabric strap 12 to separate the hook and loop fastener 13 from the hook and loop fastener 11. Then, pull the other end of the fabric strap 12 to pull one end of the fabric strap 12 out of the metal ring 10. Repeat the above operation to remove the extended sleeve 6.
[0036] In this embodiment, the fixing block 2 9 is rotatably connected to the iron ring 10.
[0037] Among them, it is ensured that the iron ring 10 can rotate normally in the fixed block 2 9.
[0038] In this embodiment, the fabric tape 12 is tightly sewn together with the hook and loop fastener surface 11 and the hook and loop fastener barbed surface 13.
[0039] This ensures the structural stability of the fabric tape 12, the hook and loop fastener 11, and the hook and loop fastener barbed fastener 13.
[0040] In this embodiment, the extended sleeve 6 is tightly sewn to the thermal insulation layer 7.
[0041] Among these measures, it is essential to ensure the structural stability of the extended sleeve 6 and the insulation layer 7.

[0043] Among them, it is necessary to ensure the structural stability of the fixing ring 4 and the sleeve 3.
[0044] In this embodiment, the fixing ring 2 5 is tightly sewn to the extended sleeve 6, and the sealing gasket 14 is tightly sewn to the fixing ring 2 5.
[0045] This ensures the structural stability of the fixing ring 2 5 and the extended sleeve 6, and guarantees the structural stability of the sealing gasket 14 and the fixing ring 2 5.
[0046] Working principle: When the weather is cold, the second fixing ring 5 can be aligned with the first fixing ring 4. At the same time, the sealing gasket 14 on the second fixing ring 5 will enter the first fixing ring 4, filling the gap between the first fixing ring 4 and the second fixing ring 5. This prevents cold air from entering the interior through the gap between the first fixing ring 4 and the second fixing ring 5. Then, pull one end of the fabric tape 12 to pass through the iron ring 10. Then, pull the fabric tape 12 in the opposite direction to wrap around the iron ring 10 and tightly attach the hook and loop fastener 13 and hook and loop fastener 11 on the fabric tape 12. Under the action of the hook and loop fastener 13 and hook and loop fastener 11, the fabric tape 12 pulls the iron ring 10, thus fixing the first fixing ring 4 and the second fixing ring 5. At the same time, the extended sleeve 6 has strong heat preservation, ensuring that the hands will not freeze in cold weather.
[0047] When the boy needs to play, the cuffs are too long. Pull one end of the fabric strap 12 to separate the Velcro hook side 13 from the Velcro loop side 11. Then, pull the other end of the fabric strap 12 to pull one end of the fabric strap 12 out of the metal ring 10. Repeat the above operation to remove the extended sleeve 6. The whole device ensures that it can provide sufficient warmth even in extremely cold weather conditions. In terms of freedom of movement, it allows the boy to move freely without restriction when wearing it, which improves the comfort of wearing it and also satisfies the boy's lively and active nature.
