Method for making trouser waist adjustment buckle and trouser waist structure.
A trouser waist adjusting buckle and a trouser waist structure relate to a size-adjustable trouser waist. Suit factories generally design trouser waist sizes based on the standard human body. But in fact, the human body shape is complex and waist sizes vary, so standard pants may not necessarily be suitable for people with corresponding body shapes. In order to solve this problem, Chinese patent application No. 90208398.8 disclosed a "movable waistband".
It includes a trouser body and a trouser waist, and is characterized by being symmetrically equipped with movable rollers, auxiliary strips, nylon tracks, and fixing pins at the front and rear joints of the trouser waistband. The movable roller includes a head surface, a base, and a track fixing pin. When the movable roller head surface and base are opened, the movable roller can move freely on the nylon track to adjust the waistline. After the waist circumference is adjusted, the movable roll is closed, and the track fixing pin is embedded in the nylon track.
The waist size can be fixed. However, since the waistband of the trousers adopts the structure of a fixed pin and the head and face, on the one hand, it is necessary to lock or open the trouser waist through the flipping of the head and face, which is inconvenient to use; on the other hand, flipping back and forth of the head and face can easily cause damage to the movable strap, and the slip buckle may appear during use. Phenomenon; third, since the waistband can only be adjusted by turning the head and face, the movement is exposed.
It is extremely inconsistent with the pants. The purpose of this utility model is to provide a trousers waist adjusting buckle and a trousers waist structure, so that the user can conveniently adjust the trousers waist circumference. According to the above purpose, the present utility model adopts such a technical solution that the adjusting buckle includes a base and a toothed belt. The spring leaf is fixed on the base, and both sides of the base are bent toward the other side to form a wrapping shape, thereby wrapping the toothed belt.
One end of the cover is upturned and the other end is bent down. There are through holes on both sides. The protrusions on the side of the base extend into the through holes. At the same time, the side of the cover is pressed against the elastic piece. When in use, the two sides of the base are wrapped with the toothed belt, and the lower bend of the press cover is stuck on the rack. Position the rack and press the upturned end of the press cover. When the press cover is bent downward, the rack can be moved. The waistband structure includes a front waistband and a back waistband.
And the separation between the front and rear waistbands is above the trouser pockets. A gap is opened in the trouser pocket, and the base of the adjusting buckle is fixed on the inner side of the front waistband, and the cover is mounted on the base; the toothed belt passes between the base and the cover, and both ends are fixed on the back waistband.
Since this utility model adopts the structure of the press cover and the spring leaf, it has a simple structure, flexible use and is not easily damaged. Installed on the waistband, all components are not exposed. To adjust the waistband, just press the cover lightly. At the same time, there are gaps in the waistband to allow the front waistband to move freely. The utility model will be further described below in conjunction with the accompanying drawings and examples.
