[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1 A down jacket with windproof and warm sleeves comprises: a down jacket body 1, sleeves 2 are arranged on the down jacket body 1, and cuffs 3 are arranged on the ends of the sleeves 2.

[0023] See also Figure 1 and Figure 3 , the cuff 3 includes an inner cuff and an outer cuff, and the outer cuff is located outside the inner cuff;

[0024] Among them, see Figure 3 The inner cuff includes a fixing belt 34 and a first airbag 35. The first airbag 35 is annular and is arranged on the inner side of the fixing belt 34. The outer cuff includes an outer layer 31 (the material of the outer layer 31 is consistent with the outer fabric material of the down jacket body 1) and a second airbag 37. The second airbag 37 is annular and is arranged on the inner side of the outer layer 31. The second airbag 37 is wrapped on the outer side of the fixing belt 34. The second airbag 37 is connected to the first airbag 35 through a conduit 36 ​​(such as a hose). The interiors of the first airbag 35 and the second airbag 37 are filled with gas (such as air).

[0025] It should be noted that when the outer cuff is on the outside of the inner cuff, the second airbag 37 is in contact with the fixing belt 34, and the two are squeezed against each other, so that the fixing belt 34 presses the first airbag 35 tightly, so that the first airbag 35 is in close contact with the user's wrist to prevent external wind from blowing in, thereby achieving a windproof and warm-keeping effect. At the same time, the second airbag 37 and the fixing belt 34 are squeezed against each other, and part of the gas inside the second airbag 37 enters the first airbag 35 through the conduit 36, causing the first airbag 35 to expand, thereby increasing the tightness of the fit between the first airbag 35 and the user's wrist and improving the windproof and warm-keeping ability of the cuff 3.

[0026] In this embodiment, as a further optimized solution, please refer to Figure 3 The length of the outer cuff is greater than that of the inner cuff; the outer cuff can wrap the inner cuff to tighten the inner cuff so that the inner cuff fits closely to the wrist of the user, thereby increasing the windproof and warmth-keeping capabilities of the cuff 3 .

[0027] In this embodiment, as a further optimized solution, please refer to Figure 2 The outer layer 31 is composed of two layers (dividing the outer layer 31 into two parts), and a second zipper assembly 33 is provided at both ends of the two layers (the second zipper assembly 33 includes two chain teeth and a slider), and the two chain teeth are respectively arranged on the ends of the two layers. By moving the slider, the two chain teeth are connected to connect the ends of the two layers together (the matching method of the chain teeth and the slider belongs to the prior art and is not described in detail here); the second air bag 37 includes two arc-shaped air bags, and the two arc-shaped air bags are respectively installed on the side walls of the two layers close to each other; after the connection between the ends of the two layers by the second zipper assembly 33 is released, the layers are folded and folded onto the outer wall of the sleeve 2, and the arc-shaped air bags are folded, that is, the inner cuff is exposed to the outside, so that the inner cuff is relaxed, so that when the person is hot, the outer cuff can be folded up to relax the inner cuff for ventilation.

[0028] In this implementation, as a further optimization solution, please refer to Figure 1 and Figure 2 Two first zipper assemblies 32 are provided on the outer side walls at both ends of the two layers (the first zipper assembly 32 has the same structure as the second zipper assembly 33), and the spacing between the first zipper assemblies 32 on the two layers gradually increases along the extension direction of the cuff 3; after the first zipper assembly 32 is pulled to close, the outer cuff is tightened again, and the end of the outer cuff close to the palm is tightened to a greater extent, so that the entrance of the cuff 3 is tightened, so that the acting force between the second air bag 37 and the fixing belt 34 is increased, so that the first air bag 35 fits the wrist more closely, and the windproof and warmth-keeping ability of the cuff 3 is increased.

[0029] In this embodiment, as a further optimized solution, please refer to Figure 1 and Figure 2 The layer and the sleeve 2 are both provided with Velcro 4 (the Velcro 4 includes a male Velcro and a female Velcro, which are respectively provided on the outer side walls of the layer and the sleeve 2); when the layer is folded onto the outer wall of the sleeve 2, the male Velcro and the female Velcro will contact each other, so as to fix the folded layer.

[0030] In this embodiment, as a further optimized solution, please refer to Figure 4The fixing belt 34 includes two elastic belts 341 (elastic belts) and two connecting belts 342 (such as cloth belts). The two connecting belts 342 are respectively arranged between the two elastic belts 341, and the two connecting belts 342 and the two elastic belts 341 form a ring member.

[0031] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 5 , the two connecting belts 342 are each provided with a storage box 344 inside, and two magnetic blocks 345 are slidably provided inside the two storage boxes 344. The magnetic poles of the two magnetic blocks 345 that are close to each other are opposite, and suction will be generated between the two; the two elastic belts 341 are each provided with a flexible connector 343 (elastic rope), and the two ends of the flexible connector 343 extend into the two storage boxes 344 respectively and are connected to one of the magnetic blocks 345, and a flexible pulling member 346 (the flexible pulling member 346 can be a rope) is provided between the magnetic block 345 and the second airbag 37; when the outer layer is folded, the flexible pulling member 343 will be pulled 46, so that the two magnetic blocks 345 in the same storage box 344 are moved away from each other, and the flexible connecting piece 343 is moved to loosen the elastic band 341, so that the fixing band 34 can be further loosened, so that the air permeability of the inner cuff is increased; when the outer layer is flipped in the opposite direction so that the outer cuff is on the outside of the inner cuff, the pulling force of the flexible pulling piece 346 on the magnetic block 345 disappears, and the two magnetic blocks 345 in the same storage box 344 are attracted to each other under the action of magnetic force, which will pull the flexible connecting piece 343 and tighten the elastic band 341, exerting pressure on the first airbag 35 to make it fit closely to the wrist of the user.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
