[0054] Embodiment 1

[0055] This embodiment provides a down trousers leg, such as Figures 1 to 5 As shown, it can not only prevent the trouser legs from moving up and exposing the ankles, thus preventing the ankles from getting frozen, but also prevent rain and snow from seeping in, thus improving the warmth retention effect.

[0056] like Figures 1 to 5As shown, the down pants legs include thermal underwear 1, a stitching structure, waterproof outer pants 3 and a connecting structure. The thermal underwear 1 includes a first fabric trouser layer 11, a second fabric trouser layer 12, a filler 14 and a first elastic member 13. The second fabric trouser layer 12 is arranged outside the first fabric trouser layer 11, and the second fabric trouser layer 12 and the first fabric trouser layer 11 are arranged to form a filling chamber. The filling chamber is filled with a filler 14, and the filler 14 can be used for heat preservation. The first elastic member 13 is arranged at one end of the first fabric trouser layer 11 close to the second fabric trouser layer 12, and is located at the lower end of the first fabric trouser layer 11. The first fabric trouser layer 11 and the first elastic member 13 are fixedly connected by the stitching structure to form an elastic closure 2, and the elastic closure 2 is configured to be used for tightening the ankle. When the user wears the down pants, the ankles extend out of the elastic cuffs 2, so that the elastic cuffs 2 can tightly bind the ankles, preventing the trouser legs from moving up due to the user's large-scale movements, and preventing the ankles from being exposed and frozen.

[0057] The waterproof outer pants 3 are sleeved outside the second fabric trouser layer 12, and the waterproof outer pants 3 include a first outer pants section 31, a second outer pants section 32 and a third outer pants section 33 which are connected in sequence. An adhesive 34 is provided at the junction of the first outer pants section 31 and the second outer pants section 32, and the adhesive 34 is used to connect part of the waterproof outer pants 3 and the second fabric trouser layer 12. By providing the adhesive 34, the waterproof outer pants 3 can be connected and fixed to the thermal underwear 1 to avoid misalignment between the two, thereby ensuring the comfort of the user. At least one fixing member 4 is provided, and the fixing member 4 is provided on the side of the third outer pants section 33 facing the second fabric trouser layer 12. A first through hole 41 is provided on the fixing member 4, and the first through hole 41 is configured to be used for threading shoelaces.

[0058] When wearing the down pants, the user's legs are inserted into the inner cavity of the thermal underwear 1, and the ankles are extended by the elastic cuffs 2. At this time, the elastic cuffs 2 can tightly bind the user's ankles. Then, the trouser legs of the thermal underwear 1 can be tucked into the inside of the shoes, and the waterproof outer pants 3 are folded upward to expose the fixing members 4 of the connecting structure. The shoelaces of the shoes are passed through the first through holes 41 of the fixing members 4, and then the waterproof outer pants 3 are folded downward to be flat, so that the waterproof outer pants 3 are wrapped around the outside of the shoes, and the shoelaces are tightened and tied to fix them.

[0059] By setting the elastic closing 2, the thermal underwear 1 can be tightly wrapped around the ankles, which can prevent cold wind from entering the inner cavity of the thermal underwear 1 and keep the user's legs warm, and can also prevent the thermal underwear 1 from moving up due to large-scale movements, prevent the user's ankles from being exposed and frozen, and ensure the warming effect; the waterproof outer pants 3 are wrapped on the outside of the shoes, and the shoelaces are passed through the first through holes 41 of the connecting and fixing parts 4, so that the waterproof outer pants 3 can be fixed, so that the waterproof outer pants 3 are always wrapped on the outside of the shoes, and the trouser legs of the waterproof outer pants 3 are prevented from twisting and shifting, and rain and snow are prevented from penetrating through the gap between the shoes and the trouser legs of the thermal underwear 1, thereby improving the warming effect.

[0060] Exemplarily, the filling material 14 includes down, and the first elastic member 13 includes an elastic band.

[0061] In this embodiment, two fixing members 4 are provided. When the user wears the down pants, the two ends of the shoelaces can be passed through the first through holes 41 of the two fixing members 4 respectively, and then tied and fixed. In other embodiments, one fixing member 4 can be provided according to actual needs. In this case, any end of the shoelace can be passed through the first through hole 41 of the fixing member 4 and tied and fixed, or more than two fixing members 4 can be provided, and the shoelaces can be passed through multiple fixing members 4 in sequence and tied and fixed. By increasing the number of fixing members 4, the connection strength between the shoes and the waterproof outer pants 3 can be improved, so that the waterproof outer pants 3 can be stably wrapped on the outside of the shoes, preventing rain and snow from penetrating through the gap, and ensuring the warmth effect.

[0062] Alternatively, if Figure 1 and Figure 2 As shown, the down pants leg also includes an anti-skid piece 5. The anti-skid piece 5 is arranged on the side of the third outer pants section 33 facing the second fabric pants layer 12, and the anti-skid piece 5 is configured to be frictionally attached to the shoe surface. When the user wears the down pants, the ankle is extended from the elastic band 2 and tied inside the shoe, the waterproof outer pants 3 are folded upward to expose the fixing piece 4, the shoelaces are passed through the first through hole 41 of the fixing piece 4, and then the waterproof outer pants 3 are folded downward to wrap the waterproof outer pants 3 on the outside of the shoe. At this time, the waterproof outer pants 3 are in friction contact with the surface of the shoe through the anti-skid piece 5, and finally the shoelaces are tightened and tied to fix the waterproof outer pants 3. By arranging the anti-skid piece 5, the friction between the waterproof outer pants 3 and the shoe can be increased, so that the inner side of the waterproof outer pants 3 can be attached to the shoe surface, preventing the waterproof outer pants 3 from everting due to large-scale movement, avoiding debris from scratching the warm liner, and further strengthening the fixing effect of the waterproof outer pants 3.

[0063] Alternatively, if Figure 1 and Figure 2 As shown, the down pants leg also includes an elastic adjustment device 6. The elastic adjustment device 6 includes a clamping member 61 and a second elastic member 62. An end of the third outer pants section 33 away from the second outer pants section 32 is provided with a mutually connected penetration channel and a second through hole 321 along the circumferential direction. Both ends of the second elastic member 62 penetrate the clamping member 61 and penetrate in the penetration channel through the second through hole 321, and both ends of the second elastic member 62 are fixedly connected to the third outer pants section 33. The clamping member 61 has a locking state for clamping the second elastic member 62 and an unlocking state for releasing the second elastic member 62. In the unlocking state, the second elastic member 62 can move along the clamping member 61.

[0064] When the user wears the down pants and ties and fixes the shoelaces, the clamping member 61 can be controlled to release the second elastic member 62, at which time the clamping member 61 is in an unlocked state, and then the second elastic member 62 is pulled out of the second through hole 321 to be drawn out of the passage, thereby reducing the length of the second elastic member 62 in the passage, thereby driving the end of the third outer trousers section 33 away from the second outer trousers section 32 to be tightened, that is, the trouser opening of the waterproof outer trousers 3 is tightened, and when the waterproof outer trousers 3 are tightly wrapped around the outside of the shoes, the second elastic member 62 is stopped from being pulled, and the clamping member 61 is controlled to clamp the second elastic member 62, at which time the clamping member 61 is in a locked state. By setting the tension adjustment device 6, the size of the trouser opening can be flexibly adjusted according to the foot size of different users, so that the trouser opening of the waterproof outer trousers 3 can be tightly wrapped around the outside of the shoes, further improving the waterproof outer trousers 3's defense effect against rain and snow, and improving the warmth retention performance.

[0065] Alternatively, if Figure 1 and Figure 2 As shown, the tension adjustment device 6 also includes a lifting member 63, a first fixing belt 64 and a second fixing belt 65. The lifting member 63 is sleeved on the second elastic member 62. When pulling the second elastic member 62, the user can directly pull the lifting member 63, which is convenient and quick. The two ends of the first fixing belt 64 are fixedly connected to the third outer trousers section 33. The first fixing belt 64 is surrounded to form a threading loop, and the second elastic member 62 passes through the threading loop. The second fixing belt 65 passes through the clamping member 61 and is fixed to the third outer trousers section 33. By setting the first fixing belt 64 and the second fixing belt 65, the second elastic member 62 and the clamping member 61 are fixed to the third outer trousers section 33 to prevent them from hanging and dragging on the ground, to prevent the user from tripping after stepping on them, and to improve the overall neatness.

[0066] Exemplarily, the second elastic member 62 comprises an elastic cord, and the clamping member 61 comprises a spring buckle.

[0067] Alternatively, if Figure 1 and Figure 2 As shown, the down pants leg also includes a sealing member 7. The sealing member 7 is provided at the junction of the second outer pants section 32 and the third outer pants section 33, and the sealing member 7 can seal the connection gap between the second outer pants section 32 and the third outer pants section 33. When the waterproof outer pants 3 are manufactured, the sealing member 7 can be provided at the junction of the second outer pants section 32 and the third outer pants section 33, so that the sealing member 7 seals the connection gap between the second outer pants section 32 and the third outer pants section 33, which can prevent rain and snow from penetrating into the down pants leg through the connection gap, improve the sealing performance, and enhance the waterproof effect.

[0068] Exemplarily, the sealing member 7 comprises a waterproof rubber strip.

[0069] It should be noted that the fixing member 4 is arranged at one end of the third outer trousers section 33 close to the second outer trousers section 32 , and the sealing member 7 can simultaneously seal the connection gap between the fixing member 4 and the third outer trousers section 33 .

[0070] Optionally, the waterproof outer pants 3 are provided with a first dart-collecting structure. The first dart-collecting structure is provided at the junction of the first outer pants section 31 and the second outer pants section 32, so that the waterproof outer pants 3 form an arc-shaped bulge. The first fabric trouser layer 11 and the second fabric trouser layer 12 are both provided with a second dart-collecting structure. The first fabric trouser layer 11 and the second fabric trouser layer 12 both include a first fabric trouser layer section 111 and a second fabric trouser layer section 112 connected to each other. The second dart-collecting structure is provided at the junction of the first fabric trouser layer section 111 and the second fabric trouser layer section 112, so that the first fabric trouser layer 11 and the second fabric trouser layer 12 both form an arc-shaped bulge. By providing the first dart-collecting structure and the second dart-collecting structure, the thermal underwear 1 and the waterproof outer pants 3 both form an arc-shaped bulge, thereby providing a space for the bending of the knees. When the user bends the knees, the arc-shaped bulge can just fit the bent knees, which is convenient for the user to exercise.

[0071] Alternatively, if Figure 1 and Figure 5 As shown, the thermal underwear 1 also includes a plurality of dividing strips 8. The plurality of dividing strips 8 are arranged between the first fabric trouser layer 11 and the second fabric trouser layer 12 to divide the filling chamber into a plurality of sub-chambers 15. A third through hole is provided on the dividing strip 8, and any two adjacent sub-chambers 15 are connected through the third through hole. Each sub-chamber 15 is filled with a filling material 14. By arranging the dividing strips 8, a three-dimensional space is formed between the first fabric trouser layer 11 and the second fabric trouser layer 12, and the plurality of dividing strips 8 divide the three-dimensional space into a plurality of sub-chambers 15, which can increase the density of the three-dimensional space, so that the filling materials 14 in the plurality of sub-chambers 15 are evenly dispersed, thereby improving the warming effect.
