Technical Field
[0001] This utility model patent relates to the field of baby cotton pants technology, and in particular to a baby cotton pants with a three-dimensional space in the crotch area. Background Technology
[0002] Winter cotton pants for babies, due to their thick fabric, reduce the space for movement in the crotch area of regular pants. Diapers can easily squeeze and rub against the baby's delicate skin, causing redness and swelling. Open-crotch pants, on the other hand, lack restraint in the crotch area and do not meet the need for warmth in winter. Especially when there is a lot of urine, the diaper sags due to gravity and is exposed in the crotch area, interfering with the baby's crawling, stepping, and other walking activities.

The fixed part completely covers the back crotch and the bottom of the crotch. The extension part is located below the fixed part to partially cover the front crotch. The edge of the extension part is provided with a middle binding strip.
[0005] The left piece is sewn together to form a single, connected left crotch and left leg. The left crotch encloses the left half of the body, with left front and left back pieces respectively on the front and back of the body. The left front piece is detachably connected to the center binding strip, and the left back piece is spliced to the left side of the fixed part. The right piece is sewn together to form a single, connected right crotch and right leg. The right crotch encloses the right half of the body, with right front and right back pieces respectively on the front and back of the body. The right back piece is spliced to the right side of the fixed part, and the right front piece is detachably connected to the center binding strip.
[0006] The left and right front panels overlap in the front part to form a covered area, and the left and right ends of the waist panel are detachably connected by Velcro.
[0007] Preferably, the overlapping area coincides with the center line of the pants body, and the right front piece overlaps the outside of the left front piece, so that the pants body forms a front opening; the waist surface at the left end of the waist piece is provided with a fleece surface, and the waist lining at the right end of the waist piece is provided with an injection hook that is attached and matched to the fleece surface.
[0008] Preferably, the left end of the waist piece is connected to the left front piece, and the right end of the waist piece is connected to the right front piece; the waist surface of the left end of the waist piece is also provided with a baffle for covering the exposed fur surface, the upper edge of the baffle is connected to the waist piece, and the lower edge and the right side of the baffle are not connected to the waist piece.
[0009] Preferably, the left front piece has a left binding strip sewn along its edge, and the right front piece has a right binding strip sewn along its edge. Both the left and right binding strips are detachably connected to the center binding strip via snap fasteners.
[0010] Preferably, the crotch insert is a tongue-shaped insert that is wider at the top and narrower at the bottom.
[0011] Preferably, both the left and right pant legs have ribbed seams at the hem.
[0012] The beneficial effects of this utility model are: by widening the crotch space through the back crotch insert, the squeezing sensation between the diaper and the baby's buttocks is reduced; by detachably connecting the left and right front pieces and the middle edge strip, a front opening is formed that facilitates diaper changes and convenient adjustment of the waist size; the back crotch insert reduces the mutual pulling effect between the left and right pant legs, while also restricting the space of the diaper to avoid interfering with the baby's walking movements.
